SPDR SERIES TRUST

Fund Summary

SPDR^® ICE Preferred Securities ETF

(formerly, SPDR Wells Fargo Preferred Stock ETF)

Investment Objective

The SPDR ICE Preferred Securities ETF (the “Fund”) seeks to provide investment results that, before fees and expenses, correspond generally to the total return performance of an index based upon Preferred Securities (as defined below).

Fees and Expenses of the Fund

The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment):

Management fees	[0.45]%
Distribution and service (12b-1) fees	None
Other expenses	[0.00]%
Total annual Fund operating expenses	[0.45]%

Example:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then sell all of your Fund Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Year 1	Year 3	Year 5	Year 10
$[46]	$[144]	$[252]	$[567]

Portfolio Turnover:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was [ ]% of the average value of its portfolio.

The Fund's Principal Investment Strategy

In seeking to track the performance of the ICE Exchange-Listed Fixed & Adjustable Rate Preferred Securities Index (the “Index”), the Fund employs a sampling strategy, which means that the Fund is not required to purchase all of the securities represented in the Index. Instead, the Fund may purchase a subset of the securities in the Index in an effort to hold a portfolio of securities with generally the same risk and return characteristics of the Index. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. Based on its analysis of these factors, SSGA Funds Management, Inc. (“SSGA FM” or the “Adviser”), the investment adviser to the Fund, either may invest the Fund's assets in a subset of securities in the Index or may invest the Fund's assets in substantially all of the securities represented in the Index in approximately the same proportions as the Index, as determined by the Adviser to be in the best interest of the Fund in pursuing its objective. The Fund is classified as “diversified” under the Investment Company Act of 1940, as amended; however, the Fund may become “non-diversified” solely as a result of tracking the Index (e.g., changes in weightings of one or more component securities). When the Fund is non-diversified, it may invest a relatively high percentage of its assets in a limited number of issuers.

Table of Contents

Under normal market conditions, the Fund generally invests substantially all, but at least 80%, of its total assets in the securities comprising the Index. In addition, in seeking to track the Index, the Fund may invest in securities that are not included in the Index, cash and cash equivalents or money market instruments, such as repurchase agreements and money market funds (including money market funds advised by the Adviser). In seeking to track the Index, the Fund's assets may be concentrated in an industry or group of industries, but only to the extent that the Index concentrates in a particular industry or group of industries. Futures contracts (a type of derivative instrument) may be used by the Fund in seeking performance that corresponds to the Index and in managing cash flows.

The Index is designed to measure the performance of non-convertible preferred stock and securities that are functionally equivalent to preferred stock, including, but not limited to, senior and subordinated debt (collectively, “Preferred Securities”). Preferred Securities generally pay fixed rate distributions (but may pay distributions based on adjustable rates) and typically have “preference” over common stock in the payment of distributions and the liquidation of a company's assets — preference means that a company must pay distributions on its Preferred Securities before paying dividends on its common stock, and the claims of Preferred Securities holders are ahead of common stockholders' claims on assets in a corporate liquidation. The Index includes Preferred Securities that meet the following criteria: (i) are non-convertible; (ii) have a par amount of $25; (iii) are primarily listed on the NYSE or NASDAQ exchanges, (iv) have a minimum amount outstanding of $250 million; (v) are U.S. dollar denominated; (vi) are rated investment grade by one of Moody's Investors Service, Inc. or Standard & Poor's Financial Services, LLC ratings services; (vii) are publicly registered or exempt from registration under the Securities Act of 1933; (viii) have a fixed or floating rate coupon or dividend schedule; (ix) have a minimum average monthly trading volume of at least 250,000 trading units during the preceding six months; and (x) have at least 18 months to final maturity at time of issuance and a minimum remaining term to final maturity of at least one day. The Index does not include auction rate preferred securities, convertible preferred shares, securities with a sinking fund, shares in closed-end funds, purchase units, purchase contracts, corporate pay-in-kind securities and derivative instruments.

The Index is market capitalization weighted. The aggregate weight of securities of an individual issuer is limited to 5%, and any weight exceeding this limit will be redistributed on a pro-rata basis to securities of issuers that do not exceed the 5% limit. In the event the Index includes securities of fewer than 20 issuers, the aggregate weight of each issuer's securities will be equally weighted and the issuer's individual securities will be weighted on a pro-rata basis. The Index is rebalanced on the last calendar day of each month based on information available up to and including the third business day before the last business day of the month. As of July 31, 2021, a significant portion of the Index comprised companies in the [financial and utilities sectors], although this may change from time to time. As of July 31, 2021, the Index comprised [ ] Preferred Securities.

The Index is sponsored by ICE Data Indices, LLC (the “Index Provider”), which is not affiliated with the Fund or the Adviser. The Index Provider determines the composition of the Index, relative weightings of the securities in the Index and publishes information regarding the market value of the Index.

Principal Risks of Investing in the Fund

As with all investments, there are certain risks of investing in the Fund. Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Market Risk: The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in the actual or perceived creditworthiness of issuers, and general market liquidity. The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments.

Equity Investing Risk: The market prices of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer and also may decline due to general industry or market conditions that are not specifically related to a particular company. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Preferred Securities Risk: Generally, Preferred Security holders have no or limited voting rights with respect to the issuing company. In addition, Preferred Securities are generally senior to common stock, but subordinated to bonds and other debt instruments in a company's capital structure and therefore will be subject to greater credit

Table of Contents

risk than those debt instruments. In the event an issuer of Preferred Securities experiences economic difficulties, the issuer's Preferred Securities may lose substantial value due to the increased likelihood of deferred interest or dividend payments and the fact that the Preferred Security may be subordinated to other securities of the same issuer. Further, because many Preferred Securities pay interest or dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds — that is, as interest rates rise, the value of the Preferred Securities held by the Fund are likely to decline. In addition, to the extent Preferred Securities allow holders to convert the Preferred Securities into common stock of the issuer, their market price can be sensitive to changes in the value of the issuer's common stock and, therefore, declining common stock values may also cause the value of the Fund's investments to decline. Preferred securities often have call features which allow the issuer to redeem the security at its discretion. The redemption of a Preferred Security having a higher than average yield may cause a decrease in the Fund's yield.

Fluctuation of Net Asset Value, Share Premiums and Discounts Risk: As with all exchange-traded funds, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund's daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). This risk is heightened in times of market volatility or periods of steep market declines.

Counterparty Risk: The Fund will be subject to credit risk with respect to the counterparties with which the Fund enters into derivatives contracts, repurchase agreements, reverse repurchase agreements, and other transactions. If a counterparty fails to meet its contractual obligations, the Fund may be unable to terminate or realize any gain on the investment or transaction, or to recover collateral posted to the counterparty, resulting in a loss to the Fund. If the Fund holds collateral posted by its counterparty, it may be delayed or prevented from realizing on the collateral in the event of a bankruptcy or insolvency proceeding relating to the counterparty.

Debt Securities Risk: The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets; the risk of low rates of return due to reinvestment of securities during periods of falling interest rates or repayment by issuers with higher coupon or interest rates; and/or the risk of low income due to falling interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. The current historically low interest rate environment heightens the risks associated with rising interest rates. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities.

Depositary Receipts Risk: Investments in depositary receipts may be less liquid and more volatile than the underlying securities in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based. To the extent the Fund invests in depositary receipts based on securities included in the Index, such differences in prices may increase index tracking risk.

Derivatives Risk: Derivative transactions can create investment leverage and may have significant volatility. It is possible that a derivative transaction will result in a much greater loss than the principal amount invested, and the Fund may not be able to close out a derivative transaction at a favorable time or price. The counterparty to a derivatives contract may be unable or unwilling to make timely settlement payments, return the Fund's margin, or otherwise honor its obligations. A derivatives transaction may not behave in the manner anticipated by the Adviser or may not have the effect on the Fund anticipated by the Adviser.

Table of Contents

Financial Sector Risk: Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.

Indexing Strategy/Index Tracking Risk: The Fund is managed with an indexing investment strategy, attempting to track the performance of an unmanaged index of securities, regardless of the current or projected performance of the Index or of the actual securities comprising the Index. This differs from an actively-managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund's performance may be less favorable than that of a portfolio managed using an active investment strategy. The structure and composition of the Index will affect the performance, volatility, and risk of the Index and, consequently, the performance, volatility, and risk of the Fund. When there are changes made to the component securities of the Index and the Fund in turn makes similar changes to its portfolio, any transaction costs and market exposure arising from such portfolio changes will be borne directly by the Fund and its shareholders. The Fund may recognize gains as a result of rebalancing or reconstituting its securities holdings to reflect changes in the securities included in the Index. The Fund also may be required to distribute any such gains to its shareholders to avoid adverse federal income tax consequences. While the Adviser seeks to track the performance of the Index (i.e., achieve a high degree of correlation with the Index), the Fund's return may not match the return of the Index. The Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities. In addition, the Fund may not be fully invested at times, generally as a result of cash flows into or out of the Fund or reserves of cash held by the Fund to meet redemptions. The Adviser may attempt to track the Index return by investing in fewer than all of the securities in the Index, or in some securities not included in the Index, potentially increasing the risk of divergence between the Fund's return and that of the Index.

Liquidity Risk: Lack of a ready market or restrictions on resale may limit the ability of the Fund to sell a security at an advantageous time or price or at all. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. Illiquidity of the Fund's holdings may limit the ability of the Fund to obtain cash to meet redemptions on a timely basis. In addition, the Fund, due to limitations on investments in any illiquid securities and/or the difficulty in purchasing and selling such investments, may be unable to achieve its desired level of exposure to a certain market or sector.

Non-Diversification Risk: To the extent the Fund becomes “non-diversified,” the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of Fund Shares may be more volatile than the values of shares of more diversified funds. The Fund may become non-diversified for periods of time solely as a result of tracking the Index (e.g., changes in weightings of one or more component securities).

Non-U.S. Securities Risk: Non-U.S. securities (including depositary receipts) are subject to political, regulatory, and economic risks not present in domestic investments. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, legal and financial report standards comparable to those in the United States. Further, such entities and/or their securities may be subject to risks associated with currency controls; expropriation; changes in tax policy; greater market volatility; differing securities market structures; higher transaction costs; and various administrative difficulties, such as delays in clearing and settling portfolio transactions or in receiving payment of dividends. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could

Table of Contents

result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Securities traded on foreign markets may be less liquid (harder to sell) than securities traded domestically. Foreign governments may impose restrictions on the repatriation of capital to the U.S. In addition, to the extent that the Fund buys securities denominated in a foreign currency, there are special risks such as changes in currency exchange rates and the risk that a foreign government could regulate foreign exchange transactions. In addition, to the extent investments are made in a limited number of countries, events in those countries will have a more significant impact on the Fund. Investments in depositary receipts may be less liquid and more volatile than the underlying shares in their primary trading market.

Unconstrained Sector Risk: The Fund may invest a substantial portion of its assets within one or more economic sectors or industries, which may change from time to time. Greater investment focus on one or more sectors or industries increases the potential for volatility and the risk that events negatively affecting such sectors or industries could reduce returns, potentially causing the value of the Fund's Shares to decrease, perhaps significantly.

Utilities Sector Risk: Utility companies are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, and rate caps or rate changes. Although rate changes of a utility usually fluctuate in approximate correlation with financing costs, due to political and regulatory factors rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company's earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility debt securities (and, to a lesser extent, equity securities) may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company's equipment unusable or obsolete and negatively impact profitability.

Among the risks that may affect utility companies are the following: risks of increases in fuel and other operating costs; the high cost of borrowing to finance capital construction during inflationary periods; restrictions on operations and increased costs and delays associated with compliance with environmental and nuclear safety regulations; and the difficulties involved in obtaining natural gas for resale or fuel for generating electricity at reasonable prices. Other risks include those related to the construction and operation of nuclear power plants, the effects of energy conservation and the effects of regulatory changes.

Fund Performance

The following bar chart and table provide an indication of the risks of investing in the Fund by showing changes in the Fund's performance from year to year and by showing how the Fund's average annual returns for certain time periods compare with the average annual returns of the Index and of a relevant broad-based securities index. The Fund's past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by calling 1-866-787-2257 or visiting our website at https://www.ssga.com/spdrs.

Annual Total Returns (years ended 12/31)*

Average Annual Total Returns (for periods ended 12/31/20)

The after-tax returns presented in the table below are calculated using highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Your actual after-tax returns will depend on your specific tax situation and may differ from those shown below. After-tax returns are not relevant to investors who hold Fund Shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts. The returns after taxes can exceed the returns before taxes due to an assumed tax benefit for a shareholder from realizing a capital loss on a sale of Fund Shares. Effective May 1, 2021 (the “Benchmark Index Change Date”), the Fund's benchmark index changed from the Wells Fargo Hybrid and Preferred Securities Aggregate Index (the “Previous

Table of Contents

Benchmark Index”) to the ICE Exchange-Listed Fixed & Adjustable Rate Preferred Securities Index, consistent with a change in the Fund's principal investment strategy to track the performance of the current index. Performance of the Fund prior to the Benchmark Index Change Date is therefore based on the Fund's investment strategy to track the Previous Benchmark Index.

Portfolio Management

Investment Adviser

SSGA FM serves as the investment adviser to the Fund.

Portfolio Managers

The professionals primarily responsible for the day-to-day management of the Fund are Michael Feehily, Karl Schneider and Amy Scofield.

Michael Feehily, CFA, is a Senior Managing Director of the Adviser and the Head of Global Equity Beta Solutions in the Americas. He worked at the Adviser from 1997 to 2006 and rejoined in 2010.

Karl Schneider, CAIA, is a Managing Director of the Adviser and Deputy Head of Global Equity Beta Solutions in the Americas. He joined the Adviser in 1997.

Amy Scofield is a Principal of the Adviser and a Portfolio Manager in the Global Equity Beta Solutions Group. She joined the Adviser in 2010.

Purchase and Sale Information

The Fund will issue (or redeem) Fund Shares to certain institutional investors (typically market makers or other broker-dealers) only in large blocks of Fund Shares known as “Creation Units.” Creation Unit transactions are conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities and/or cash.

Individual Fund Shares may only be purchased and sold on the NYSE Arca, Inc., other national securities exchanges, electronic crossing networks and other alternative trading systems through your broker-dealer at market prices. Because Fund Shares trade at market prices rather than at net asset value (“NAV”), Fund Shares may trade at a price greater than NAV (premium) or less than NAV (discount). When buying or selling Fund Shares in the secondary market, you may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Fund Shares (bid) and the lowest price a seller is willing to accept for Fund Shares (ask) (the “bid-ask spread”). Recent information regarding the Fund's NAV, market price, premiums and discounts, and bid-ask spreads is available at https://www.ssga.com/spdrs.

Tax Information

The Fund's distributions are expected to be taxed as ordinary income, qualified dividend income and/or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or individual retirement account. Any withdrawals made from such tax-advantaged arrangement may be taxable to you.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase Fund Shares through a broker-dealer or other financial intermediary (such as a bank), the Adviser or its affiliates may pay the financial intermediary for certain activities related to the Fund, including educational training programs, conferences, the development of technology platforms and reporting systems, or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.

Additional Strategies Information

Principal Strategies

General. Please see “The Fund's Principal Investment Strategy” section under “Fund Summary” above for a complete discussion of the Fund's principal investment strategy. The Fund may invest in various types of securities and engage in various investment techniques which are not the principal focus of the Fund and therefore are not described in this Prospectus. These securities, techniques and practices, together with their risks, are described in the Statement of Additional Information (the “SAI”), which you may obtain free of charge by contacting shareholder services (see the back cover of this Prospectus for the address and phone number).

The Adviser seeks to track the performance of the Fund's Index as closely as possible (i.e., obtain a high degree of correlation with the Index). A number of factors may affect the Fund's ability to achieve a high degree of correlation with its Index, and there can be no guarantee that the Fund will achieve a high degree of correlation. For example, the Fund may not be able to achieve a high degree of correlation with its Index when there are practical difficulties or substantial costs involved in compiling a portfolio of securities to follow the Index, when a security in the Index becomes temporarily illiquid, unavailable or less liquid, or legal restrictions exist that prohibit the Fund from investing in a security in the Index.

The Adviser will utilize a sampling strategy in managing the Fund. Sampling means that the Adviser uses quantitative analysis to select securities, including securities in the Index, outside of the Index and derivatives that have a similar investment profile as the Index in terms of key risk factors, performance attributes and other economic characteristics. These include industry weightings, market capitalization, and other financial characteristics of securities. The quantity of holdings in the Fund will be based on a number of factors, including asset size of the Fund. In addition, from time to time, securities are added to or removed from the Index. The Adviser may sell securities that are represented in the Index, or purchase securities that are not yet represented in the Index, in anticipation of their removal from or addition to the Index. Further, the Adviser may choose to overweight securities in the Index, purchase or sell securities not in the Index, or utilize various combinations of other available techniques, in seeking to track the Index.

The Fund has adopted a non-fundamental investment policy to invest at least 80% of its net assets, plus the amount of borrowings for investment purposes, in investments suggested by its name, measured at the time of investment. The Fund will provide shareholders with at least 60 days' notice prior to any change in this non-fundamental 80% investment policy. The Board of Trustees of the Trust (the “Board”) may change the Fund's investment strategy, Index and other policies without shareholder approval, except as otherwise indicated in this Prospectus or in the SAI. The Board may also change the Fund's investment objective without shareholder approval.

Non-Principal Strategies

Certain Other Investments. The Fund may invest in structured notes (notes on which the amount of principal repayment and interest payments are based on the movement of one or more specified factors such as the movement of a particular security or index), swaps, options and futures contracts. Swaps, options and futures contracts and structured notes may be used by the Fund in seeking performance that corresponds to its Index and in managing cash flows.

Temporary Defensive Positions. In certain situations or market conditions, the Fund may temporarily depart from its normal investment policies and strategies, provided that the alternative is consistent with the Fund's investment objective and is in the best interest of the Fund. For example, the Fund may make larger than normal investments in derivatives to maintain exposure to its Index if it is unable to invest directly in a component security.

Borrowing Money. The Fund may borrow money from a bank as permitted by the Investment Company Act of 1940, as amended (“1940 Act”), or other governing statute, by the Rules thereunder, or by the U.S. Securities and Exchange Commission (“SEC”) or other regulatory agency with authority over the Fund, but only for temporary or emergency purposes. The Fund may also invest in reverse repurchase agreements, which are considered borrowings under the 1940 Act. Although the 1940 Act presently allows the Fund to borrow from any bank (including pledging, mortgaging or hypothecating assets) in an amount up to 33¹/₃% of its total assets (not including temporary borrowings not in excess of 5% of its total assets), and there is no percentage limit on Fund assets that can be used in connection with reverse repurchase agreements, under normal circumstances any borrowings by the Fund will not exceed 10% of the Fund's total assets.

Table of Contents

Lending of Securities. The Fund may lend its portfolio securities in an amount not to exceed 40% of the value of its net assets via a securities lending program through its securities lending agent, State Street Bank and Trust Company (“State Street” or the “Lending Agent”), to brokers, dealers and other financial institutions desiring to borrow securities to complete transactions and for other purposes. A securities lending program allows the Fund to receive a portion of the income generated by lending its securities and investing the respective collateral. The Fund will receive collateral for each loaned security which is at least equal to the market value of that security, marked to market each trading day. In the securities lending program, the borrower generally has the right to vote the loaned securities; however, the Fund may call loans to vote proxies if a material issue affecting the Fund's economic interest in the investment is to be voted upon. Security loans may be terminated at any time by the Fund.

Additional Risk Information

The following section provides information regarding the principal risks identified under “Principal Risks of Investing in the Fund” in the Fund Summary along with additional risk information.

Principal Risks

Counterparty Risk. The Fund will be subject to credit risk with respect to the counterparties with which the Fund enters into derivatives contracts and other transactions such as repurchase agreements or reverse repurchase agreements. The Fund's ability to profit from these types of investments and transactions will depend on the willingness and ability of its counterparty to perform its obligations. If a counterparty fails to meet its contractual obligations, the Fund may be unable to terminate or realize any gain on the investment or transaction, resulting in a loss to the Fund. The Fund may experience significant delays in obtaining any recovery in an insolvency, bankruptcy, or other reorganization proceeding involving its counterparty (including recovery of any collateral posted by it) and may obtain only a limited recovery or may obtain no recovery in such circumstances. If the Fund holds collateral posted by its counterparty, it may be delayed or prevented from realizing on the collateral in the event of a bankruptcy or insolvency proceeding relating to the counterparty. Under applicable law or contractual provisions, including if the Fund enters into an investment or transaction with a financial institution and such financial institution (or an affiliate of the financial institution) experiences financial difficulties, then the Fund may in certain situations be prevented or delayed from exercising its rights to terminate the investment or transaction, or to realize on any collateral and may result in the suspension of payment and delivery obligations of the parties under such investment or transactions or in another institution being substituted for that financial institution without the consent of the Fund. Further, the Fund may be subject to “bail-in” risk under applicable law whereby, if required by the financial institution's authority, the financial institution's liabilities could be written down, eliminated or converted into equity or an alternative instrument of ownership. A bail-in of a financial institution may result in a reduction in value of some or all of its securities and, if the Fund holds such securities or has entered into a transaction with such a financial security when a bail-in occurs, the Fund may also be similarly impacted.

Debt Securities Risk. The values of debt securities may increase or decrease as a result of the following: market fluctuations, changes in interest rates, actual or perceived inability or unwillingness of issuers, guarantors or liquidity providers to make scheduled principal or interest payments or illiquidity in debt securities markets; the risk of low rates of return due to reinvestment of securities during periods of falling interest rates or repayment by issuers with higher coupon or interest rates; and/or the risk of low income due to falling interest rates. To the extent that interest rates rise, certain underlying obligations may be paid off substantially slower than originally anticipated and the value of those securities may fall sharply. A rising interest rate environment may cause the value of the Fund's fixed income securities to decrease,a decline in the Fund's income and yield, an adverse impact on the liquidity of the Fund's fixed income securities, and increased volatility of the fixed income markets. The current historically low interest rate environment heightens the risks associated with rising interest rates. During periods when interest rates are at low levels, the Fund's yield can be low, and the Fund may have a negative yield (i.e., it may lose money on an operating basis). If the principal on a debt obligation is prepaid before expected, the prepayments of principal may have to be reinvested in obligations paying interest at lower rates. During periods of falling interest rates, the income received by the Fund may decline. Changes in interest rates will likely have a greater effect on the values of debt securities of longer durations. Returns on investments in debt securities could trail the returns on other investment options, including investments in equity securities.

Table of Contents

Depositary Receipts Risk. American Depositary Receipts (“ADRs”) are typically trust receipts issued by a U.S. bank or trust company that evidence an indirect interest in underlying securities issued by a foreign entity. Global Depositary Receipts (“GDRs”), European Depositary Receipts (“EDRs”), and other types of depositary receipts are typically issued by non-U.S. banks or financial institutions to evidence an interest in underlying securities issued by either a U.S. or a non-U.S. entity. Investments in non-U.S. issuers through ADRs, GDRs, EDRs, and other types of depositary receipts generally involve risks applicable to other types of investments in non-U.S. issuers. Investments in depositary receipts may be less liquid and more volatile than the underlying securities in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. There may be less publicly available information regarding the issuer of the securities underlying a depositary receipt than if those securities were traded directly in U.S. securities markets. Depositary receipts may or may not be sponsored by the issuers of the underlying securities, and information regarding issuers of securities underlying unsponsored depositary receipts may be more limited than for sponsored depositary receipts. The values of depositary receipts may decline for a number of reasons relating to the issuers or sponsors of the depositary receipts, including, but not limited to, insolvency of the issuer or sponsor. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based. To the extent the Fund invests in depositary receipts based on securities included in its Index, such differences in prices may increase index tracking risk.

Derivatives Risk. A derivative is a financial contract the value of which depends on, or is derived from, the value of an underlying asset, interest rate, or index. Derivative transactions typically involve leverage and may have significant volatility. It is possible that a derivative transaction will result in a loss greater than the principal amount invested, and the Fund may not be able to close out a derivative transaction at a favorable time or price. Risks associated with derivative instruments include potential changes in value in response to interest rate changes or other market developments or as a result of the counterparty's credit quality; the potential for the derivative transaction not to have the effect the Adviser anticipated or a different or less favorable effect than the Adviser anticipated; the failure of the counterparty to the derivative transaction to perform its obligations under the transaction or to settle a trade; possible mispricing or improper valuation of the derivative instrument; imperfect correlation in the value of a derivative with the asset, rate, or index underlying the derivative; the risk that the Fund may be required to post collateral or margin with its counterparty, and will not be able to recover the collateral or margin in the event of the counterparty's insolvency or bankruptcy; the risk that the Fund will experience losses on its derivatives investments and on its other portfolio investments, even when the derivatives investments may be intended in part or entirely to hedge those portfolio investments; the risks specific to the asset underlying the derivative instrument; lack of liquidity for the derivative instrument, including without limitation absence of a secondary trading market; the potential for reduced returns to the Fund due to losses on the transaction and an increase in volatility; the potential for the derivative transaction to have the effect of accelerating the recognition of gain; and legal risks arising from the documentation relating to the derivative transaction.

Futures Contract Risk; Other Exchange-Traded Derivatives Risk. The risk of loss relating to the use of futures contracts and other exchange-traded derivatives is potentially unlimited. The ability to establish and close out positions in futures contracts and other exchange-traded derivatives will be subject to the development and maintenance of a liquid secondary market. There is no assurance that a liquid secondary market on an exchange will exist for any particular futures contract or other exchange-traded derivative or at any particular time. In the event no such market exists for a particular derivative, it might not be possible to effect closing transactions, and the Fund will be unable to terminate the derivative. In using futures contracts and other exchange-traded derivatives, the Fund will be reliant on the ability of the Adviser to predict market and price movements correctly; the skills needed to use such derivatives successfully are different from those needed for traditional portfolio management. If the Fund uses futures contracts or other exchange-traded derivatives for hedging purposes, there is a risk of imperfect correlation between movements in the prices of the derivatives and movements in the securities or index underlying the derivatives or movements in the prices of the Fund's investments that are the subject of such hedge. The prices of futures and other exchange-traded derivatives, for a number of reasons, may not correlate perfectly with movements in the securities or index underlying them. For example, participants in the futures markets and in markets for other exchange-traded derivatives are subject to margin deposit requirements. Such requirements may cause investors to take actions with respect to their derivatives positions that they would not otherwise take. The margin requirements in the derivatives markets may be less onerous than margin

Table of Contents

requirements in the securities markets in general, and as a result those markets may attract more speculators than the securities markets do. Increased participation by speculators in those markets may cause temporary price distortions. Due to the possibility of price distortion, even a correct forecast of general market trends by the Adviser still may not result in a successful derivatives activity over a very short time period. The risk of a position in a futures contract or other exchange-traded derivative may be very large compared to the relatively low level of margin the Fund is required to deposit. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The Fund will incur brokerage fees in connection with its exchange-traded derivatives transactions. The Fund will typically be required to post margin with its futures commission merchant in connection with its transactions in futures contracts and other exchange-traded derivatives. In the event of an insolvency of the futures commission merchant or a clearing house, the Fund may not be able to recover all (or any) of the margin it has posted with the futures commission merchant, or to realize the value of any increase in the price of its positions, or it may experience a significant delay in doing so. The Fund also may be delayed or prevented from recovering margin or other amounts deposited with a futures commission merchant or futures clearinghouse. The Commodity Futures Trading Commission (the “CFTC”) and the various exchanges have established limits referred to as “speculative position limits” on the maximum net long or net short positions that any person and certain affiliated entities may hold or control in a particular futures contract. Trading limits are imposed on the number of contracts that any person may trade on a particular trading day. An exchange may order the liquidation of positions found to be in violation of these limits and it may impose sanctions or restrictions. In addition, the Dodd-Frank Act requires the CFTC to establish speculative position limits on certain commodity futures contracts and their economically equivalent futures, options and swaps. Regulatory action taken by the CFTC to establish these additional position limits may adversely affect the market liquidity of the futures, options and economically equivalent derivatives in which the Fund may invest. It is possible that, as a result of such limits, the Fund's Adviser will be precluded from taking positions in certain futures contracts or over-the-counter derivatives as a result of positions held by other clients of the Adviser or by the Adviser or its affiliates themselves.

Futures contracts and other exchange-traded derivatives traded on markets outside the U.S. are not generally subject to the same level of regulation by the CFTC or other U.S. regulatory entities as contracts traded in the U.S., including without limitation as to the execution, delivery, and clearing of transactions. U.S. regulators neither regulate the activities of a foreign exchange, nor have the power to compel enforcement of the rules of the foreign exchange or the laws of the foreign country in question. Margin and other payments made by the Fund may not be afforded the same protections as are afforded those payments in the U.S., including in connection with the insolvency of an executing or clearing broker or a clearinghouse or exchange. Certain foreign futures contracts and other exchange-traded derivatives may be less liquid and more volatile than U.S. contracts.

Equity Investing Risk. The market prices of equity securities owned by the Fund may go up or down, sometimes rapidly or unpredictably. The value of a security may decline for a number of reasons that may directly relate to the issuer, such as management performance, financial leverage, non-compliance with regulatory requirements, and reduced demand for the issuer's goods or services. The values of equity securities also may decline due to general industry or market conditions that are not specifically related to a particular company, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates, or adverse investor sentiment generally. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

Financial Sector Risk. Financial services companies are subject to extensive governmental regulation which may limit both the amounts and types of loans and other financial commitments they can make, the interest rates and fees they can charge, the scope of their activities, the prices they can charge and the amount of capital they must maintain. Profitability is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change or due to increased competition. In addition, deterioration of the credit markets generally may cause an adverse impact in a broad range of markets, including U.S. and international credit and interbank money markets generally, thereby affecting a wide range of financial institutions and markets. Certain events in the financial sector may cause an unusually high degree of volatility in the financial markets, both domestic and foreign, and cause certain financial services companies to incur large losses. Securities of financial services companies may experience a dramatic decline in value when such companies experience substantial declines in the valuations of their assets, take action to raise capital (such as the issuance of debt or equity securities), or cease operations. Credit losses

Table of Contents

resulting from financial difficulties of borrowers and financial losses associated with investment activities can negatively impact the sector. Insurance companies may be subject to severe price competition. Adverse economic, business or political developments could adversely affect financial institutions engaged in mortgage finance or other lending or investing activities directly or indirectly connected to the value of real estate.

Fluctuation of Net Asset Value, Share Premiums and Discounts Risk. The net asset value of Fund Shares will generally fluctuate with changes in the market value of the Fund's securities holdings. The market prices of Fund Shares will generally fluctuate in accordance with changes in the Fund's net asset value and supply and demand of Fund Shares on the Exchange. It cannot be predicted whether Fund Shares will trade below, at or above their net asset value. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Fund Shares will be closely related to, but not identical to, the same forces influencing the prices of the securities of the Index trading individually or in the aggregate at any point in time. The market prices of Fund Shares may deviate significantly from the net asset value of Fund Shares during periods of market volatility. However, given that Fund Shares can be created and redeemed in Creation Units (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their net asset value), the Adviser believes that large discounts or premiums to the net asset value of Fund Shares should not be sustained over long periods. While the creation/redemption feature is designed to make it likely that Fund Shares normally will trade close to the Fund's net asset value, disruptions to creations and redemptions or market volatility may result in trading prices that differ significantly from the Fund's net asset value. If an investor purchases Fund Shares at a time when the market price is at a premium to the net asset value of Fund Shares or sells at a time when the market price is at a discount to the net asset value of Fund Shares, then the investor may sustain losses.

Indexing Strategy/Index Tracking Risk. The Fund is managed with an indexing investment strategy, attempting to track the performance of an unmanaged index of securities. The Fund will seek to replicate Index returns, regardless of the current or projected performance of the Index or of the actual securities comprising the Index. This differs from an actively-managed fund, which typically seeks to outperform a benchmark index. The Fund generally will buy and will not sell a security included in the Index as long as the security is part of the Index regardless of any sudden or material decline in value or foreseeable material decline in value of the security, even though the Adviser may make a different investment decision for other actively managed accounts or portfolios that hold the security. As a result, the Fund's performance may be less favorable than that of a portfolio managed using an active investment strategy. The structure and composition of the Index will affect the performance, volatility, and risk of the Index (in absolute terms and by comparison with other indices) and, consequently, the performance, volatility, and risk of the Fund. Errors in index data, index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the Fund and its shareholders. While the Adviser seeks to track the performance of the Index (i.e., achieve a high degree of correlation with the Index), the Fund's return may not match the return of the Index for a number of reasons. For example, the return on the sample of securities purchased by the Fund (or the return on securities not included in the Index) to replicate the performance of the Index may not correlate precisely with the return of the Index. The Fund incurs a number of operating expenses not applicable to the Index, and incurs costs in buying and selling securities. In addition, the Fund may not be fully invested at times, either as a result of cash flows into or out of the Fund or reserves of cash held by the Fund to meet redemptions. The Adviser may attempt to track the Index return by investing in fewer than all of the securities in the Index, or in some securities not included in the Index, potentially increasing the risk of divergence between the Fund's return and that of the Index. Changes in the composition of the Index and regulatory requirements also may impact the Fund's ability to match the return of the Index. The Adviser may apply one or more “screens” or investment techniques to refine or limit the number or types of issuers included in the Index in which the Fund may invest. Application of such screens or techniques may result in investment performance below that of the Index and may not produce results expected by the Adviser. Index tracking risk may be heightened during times of increased market volatility or other unusual market conditions.

Pursuant to the Index methodology, a security may be removed from the Index in the event that it does not comply with the eligibility requirements of the Index. As a result, the Fund may be forced to sell securities at inopportune times and/or unfavorable prices due to these changes in the Index components. When there are changes made to the component securities of the Index and the Fund in turn makes similar changes to its portfolio to attempt to increase the correlation between the Fund's portfolio and the Index, any transaction costs and market exposure arising from such portfolio changes will be borne directly by the Fund and its shareholders. Unscheduled changes to the Index may

Table of Contents

expose the Fund to additional tracking error risk. The Fund may recognize gains as a result of rebalancing or reconstituting its securities holdings to reflect changes in the securities included in the Index. The Fund also may be required to distribute any such gains to its shareholders to avoid adverse federal income tax consequences.

Leveraging Risk. Borrowing transactions, reverse repurchase agreements, certain derivatives transactions, securities lending transactions and other investment transactions such as when-issued, delayed-delivery, or forward commitment transactions may create investment leverage. If the Fund engages in transactions that have a leveraging effect on the Fund's investment portfolio, the value of the Fund will be potentially more volatile and all other risks will tend to be compounded. This is because leverage generally creates investment risk with respect to a larger base of assets than the Fund would otherwise have and so magnifies the effect of any increase or decrease in the value of the Fund's underlying assets. The use of leverage is considered to be a speculative investment practice and may result in losses to the Fund. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. The use of leverage may cause the Fund to liquidate positions when it may not be advantageous to do so to satisfy repayment, interest payment, or margin obligations or to meet asset segregation or coverage requirements.

Liquidity Risk. Liquidity risk is the risk that the Fund may not be able to dispose of securities or close out derivatives transactions readily at a favorable time or prices (or at all) or at prices approximating those at which the Fund currently values them. For example, certain investments may be subject to restrictions on resale, may trade in the over-the-counter market or in limited volume, or may not have an active trading market. Illiquid securities may trade at a discount from comparable, more liquid investments and may be subject to wide fluctuations in market value. It may be difficult for the Fund to value illiquid securities accurately. The market for certain investments may become illiquid under adverse market or economic conditions independent of any specific adverse changes in the conditions of a particular issuer. Disposal of illiquid securities may entail registration expenses and other transaction costs that are higher than those for liquid securities. The Fund may seek to borrow money to meet its obligations (including among other things redemption obligations) if it is unable to dispose of illiquid investments, resulting in borrowing expenses and possible leveraging of the Fund.

Market Risk. Market prices of investments held by the Fund will go up or down, sometimes rapidly or unpredictably. The Fund's investments are subject to changes in general economic conditions, general market fluctuations and the risks inherent in investment in securities markets. Investment markets can be volatile, and prices of investments can change substantially due to various factors including, but not limited to, economic growth or recession, changes in interest rates, changes in actual or perceived creditworthiness of issuers and general market liquidity. Even if general economic conditions do not change, the value of an investment in the Fund could decline if the particular industries, sectors or companies in which the Fund invests do not perform well or are adversely affected by events. Further, legal, political, regulatory and tax changes also may cause fluctuations in markets and securities prices. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, or other events could have a significant impact on the Fund and its investments.

An outbreak of a respiratory disease caused by a novel coronavirus (known as COVID-19) first detected in China in December 2019 has resulted in a global pandemic and major disruptions to economies and markets around the world, including the United States. Financial markets experienced and may continue to experience extreme volatility and severe losses, and trading in many instruments was and may continue to be disrupted as a result. Liquidity for many instruments was and may continue to be greatly reduced for periods of time. Some interest rates are very low and in some cases yields are negative. Governments and central banks, including the Federal Reserve in the United States, have taken extraordinary and unprecedented actions to support local and global economies and the financial markets. The impact of these measures, and whether they will be effective to mitigate the economic and market disruption, will not be known for some time. In addition, the outbreak of COVID-19, and measures taken to mitigate its effects, could result in disruptions to the services provided to the Fund by its service providers.

Non-Diversification Risk. To the extent the Fund becomes “non-diversified,” the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of Fund Shares may be more volatile than the values of shares of more diversified funds. The Fund may become non-diversified for periods of time solely as a result of tracking its Index (e.g., changes in weightings of one or more component securities).

Table of Contents

Non-U.S. Securities Risk. Investments in securities of non-U.S. issuers (including depositary receipts) entail risks not typically associated with investing in securities of U.S. issuers. Similar risks may apply to securities traded on a U.S. securities exchange that are issued by entities with significant exposure to non-U.S. countries. In certain countries, legal remedies available to investors may be more limited than those available with regard to U.S. investments. Because non-U.S. securities are typically denominated and traded in currencies other than the U.S. dollar, the value of the Fund's assets, to the extent they are non-U.S. dollar denominated, may be affected favorably or unfavorably by currency exchange rates, exchange control regulations, and restrictions or prohibitions on the repatriation of non-U.S. currencies. To the extent underlying securities held by the Fund trade on foreign exchanges that are closed when the exchange on which the Fund's shares trade is open, there may be deviations between the current price of an underlying security and the last quoted price for the underlying security on the closed foreign market. These deviations could result in the Fund experiencing premiums or discounts greater than those of ETFs that invest in domestic securities. Income and gains with respect to investments in certain countries may be subject to withholding and other taxes. There may be less information publicly available about a non-U.S. entity than about a U.S. entity, and many non-U.S. entities are not subject to accounting, auditing, and financial reporting standards, regulatory framework and practices comparable to those in the United States. The securities of some non-U.S. entities are less liquid and at times more volatile than securities of comparable U.S. entities, and could become subject to sanctions or embargoes that adversely affect the Fund's investment. Non-U.S. transaction costs, such as brokerage commissions and custody costs may be higher than in the U.S. In addition, there may be a possibility of nationalization or expropriation of assets, imposition of currency exchange controls, confiscatory taxation, and diplomatic developments that could adversely affect the values of the Fund's investments in certain non-U.S. countries. Investments in securities of non-U.S. issuers also are subject to foreign political and economic risk not associated with U.S. investments, meaning that political events (civil unrest, national elections, changes in political conditions and foreign relations, imposition of exchange controls and repatriation restrictions), social and economic events (labor strikes, rising inflation) and natural disasters occurring in a country where the Fund invests could cause the Fund's investments in that country to experience gains or losses.

Preferred Securities Risk. Generally, preferred security holders have no or limited voting rights with respect to the issuing company. In addition, preferred securities are generally senior to common stock, but subordinated to bonds and other debt instruments in a company's capital structure and therefore will be subject to greater credit risk than those debt instruments. In the event an issuer of preferred securities experiences economic difficulties, the issuer's preferred securities may lose substantial value due to the increased likelihood of deferred interest or dividend payments and the fact that the preferred security may be subordinated to other securities of the same issuer. Further, because many preferred securities pay interest or dividends at a fixed rate, their market price can be sensitive to changes in interest rates in a manner similar to bonds - that is, as interest rates rise, the value of the preferred securities held by the Fund are likely to decline. Therefore, to the extent that the Fund invests a substantial portion of its assets in fixed rate preferred securities, rising interest rates may cause the value of the Fund's investments to decline significantly. In addition, to the extent preferred securities allow holders to convert the preferred securities into common stock of the issuer, their market price can be sensitive to changes in the value of the issuer's common stock and, therefore, declining common stock values may also cause the value of the Fund's investments to decline. Preferred securities often have call features which allow the issuer to redeem the security at its discretion. The redemption of a preferred security having a higher than average yield may cause a decrease in the Fund's yield.

Settlement Risk. Markets in different countries have different clearance and settlement procedures and in certain markets there have been times when settlements have been unable to keep pace with the volume of transactions. Delays in settlement may increase credit risk to the Fund, limit the ability of the Fund to reinvest the proceeds of a sale of securities, hinder the ability of the Fund to lend its portfolio securities, and potentially subject the Fund to penalties for its failure to deliver to on-purchasers of securities whose delivery to the Fund was delayed. Delays in the settlement of securities purchased by the Fund may limit the ability of the Fund to sell those securities at times and prices it considers desirable, and may subject the Fund to losses and costs due to its own inability to settle with subsequent purchasers of the securities from it. The Fund may be required to borrow monies it had otherwise expected to receive in connection with the settlement of securities sold by it, in order to meet its obligations to others. Limits on the ability of the Fund to purchase or sell securities due to settlement delays could increase any variance between the Fund's performance and that of its benchmark index.

Table of Contents

Unconstrained Sector Risk. The Fund may invest a substantial portion of its assets within one or more economic sectors or industries, which may change from time to time. When the Fund focuses its investments in a particular industry or sector, financial, economic, business, and other developments affecting issuers in that industry, market, or economic sector will have a greater effect on the Fund than if it had not focused its assets in that industry, market, or economic sector, which may increase the volatility of the Fund.

Utilities Sector Risk. Utility companies are affected by supply and demand, operating costs, government regulation, environmental factors, liabilities for environmental damage and general civil liabilities, and rate caps or rate changes. Although rate changes of a utility usually fluctuate in approximate correlation with financing costs, due to political and regulatory factors, rate changes ordinarily occur only following a delay after the changes in financing costs. This factor will tend to favorably affect a regulated utility company's earnings and dividends in times of decreasing costs, but conversely, will tend to adversely affect earnings and dividends when costs are rising. The value of regulated utility debt securities (and, to a lesser extent, equity securities) may tend to have an inverse relationship to the movement of interest rates. Certain utility companies have experienced full or partial deregulation in recent years. These utility companies are frequently more similar to industrial companies in that they are subject to greater competition and have been permitted by regulators to diversify outside of their original geographic regions and their traditional lines of business. These opportunities may permit certain utility companies to earn more than their traditional regulated rates of return. Some companies, however, may be forced to defend their core business and may be less profitable. In addition, natural disasters, terrorist attacks, government intervention or other factors may render a utility company's equipment unusable or obsolete and negatively impact profitability.

Non-Principal Risks

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”), which are responsible for the creation and redemption activity for the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Transaction Risk. To the extent the Fund sells portfolio securities to meet some or all of a redemption request with cash, the Fund may incur taxable gains or losses that it might not have incurred had it made redemptions entirely in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Concentration Risk. The Fund's assets will generally be concentrated in an industry or group of industries to the extent that the Fund's underlying Index concentrates in a particular industry or group of industries. When the Fund focuses its investments in a particular industry or sector, financial, economic, business, and other developments affecting issuers in that industry, market, or economic sector will have a greater effect on the Fund than if it had not focused its assets in that industry, market, or economic sector, which may increase the volatility of the Fund.

Conflicts of Interest Risk. An investment in the Fund will be subject to a number of actual or potential conflicts of interest. For example, the Adviser or its affiliates may provide services to the Fund, such as securities lending agency services, custodial, administrative, bookkeeping, and accounting services, transfer agency and shareholder servicing, securities brokerage services, and other services for which the Fund would compensate the Adviser and/or such affiliates. The Fund may invest in other pooled investment vehicles sponsored, managed, or otherwise affiliated with the Adviser. There is no assurance that the rates at which the Fund pays fees or expenses to the Adviser or its affiliates, or the terms on which it enters into transactions with the Adviser or its affiliates will be the most favorable available in the market generally or as favorable as the rates the Adviser or its affiliates make available to other clients.

Table of Contents

Because of its financial interest, the Adviser will have an incentive to enter into transactions or arrangements on behalf of the Fund with itself or its affiliates in circumstances where it might not have done so in the absence of that interest, provided that the Adviser will comply with applicable regulatory requirements.

The Adviser and its affiliates serve as investment adviser to other clients and may make investment decisions that may be different from those that will be made by the Adviser on behalf of the Fund. For example, the Adviser may provide asset allocation advice to some clients that may include a recommendation to invest in or redeem from particular issuers while not providing that same recommendation to all clients invested in the same or similar issuers. The Adviser may (subject to applicable law) be simultaneously seeking to purchase (or sell) investments for the Fund and to sell (or purchase) the same investment for accounts, funds, or structured products for which it serves as asset manager, or for other clients or affiliates. The Adviser and its affiliates may invest for clients in various securities that are senior, pari passu or junior to, or have interests different from or adverse to, the securities that are owned by the Fund. The Adviser or its affiliates, in connection with its other business activities, may acquire material nonpublic confidential information that may restrict the Adviser from purchasing securities or selling securities for itself or its clients (including the Fund) or otherwise using such information for the benefit of its clients or itself.

The foregoing does not purport to be a comprehensive list or complete explanation of all potential conflicts of interests which may affect the Fund. The Fund may encounter circumstances, or enter into transactions, in which conflicts of interest that are not listed or discussed above may arise.

Costs of Buying and Selling Shares. Investors buying or selling Fund Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Fund Shares. In addition, secondary market investors will also incur the cost of the difference between the price that an investor is willing to pay for Fund Shares (the “bid” price) and the price at which an investor is willing to sell Fund Shares (the “ask” price). This difference in bid and ask prices is often referred to as the “spread” or “bid/ask spread.” The bid/ask spread varies over time for Fund Shares based on trading volume and market liquidity, and is generally lower if Fund Shares have more trading volume and market liquidity and higher if Fund Shares have little trading volume and market liquidity. Further, increased market volatility may cause increased bid/ask spreads. Due to the costs of buying or selling Fund Shares, including bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments.

Cybersecurity Risk. With the increased use of technologies such as the Internet and the dependence on computer systems to perform business and operational functions, funds (such as the Fund) and their service providers (including the Adviser) may be prone to operational and information security risks resulting from cyber-attacks and/or technological malfunctions. In general, cyber-attacks are deliberate, but unintentional events may have similar effects. Cyber-attacks include, among others, stealing or corrupting data maintained online or digitally, preventing legitimate users from accessing information or services on a website, releasing confidential information without authorization, and causing operational disruption. Successful cyber-attacks against, or security breakdowns of, the Fund, the Adviser or a custodian, transfer agent, or other affiliated or third-party service provider may adversely affect the Fund or its shareholders. For instance, cyber-attacks or technical malfunctions may interfere with the processing of shareholder or other transactions, affect the Fund's ability to calculate its NAV, cause the release of private shareholder information or confidential Fund information, impede trading, cause reputational damage, and subject the Fund to regulatory fines, penalties or financial losses, reimbursement or other compensation costs, and additional compliance costs. Cyber-attacks or technical malfunctions may render records of Fund assets and transactions, shareholder ownership of Fund Shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. The Fund may also incur substantial costs for cybersecurity risk management in order to prevent cyber incidents in the future. The Fund and its shareholders could be negatively impacted as a result. While the Adviser has established a business continuity plan and systems designed to minimize the risk of cyber-attacks through the use of technology, processes and controls, there are inherent limitations in such plan and systems, including the possibility that certain risks have not been identified, given the evolving nature of this threat. The Fund relies on third-party service providers for many of its day-to-day operations, and will be subject to the risk that the protections and protocols implemented by those service providers will be ineffective to protect the Fund from cyber-attack. The Adviser does not control the cybersecurity plans and systems put in place by third-party service providers, and such third-party service providers

Table of Contents

may have limited indemnification obligations to the Adviser or the Fund. Similar types of cybersecurity risks or technical malfunctions also are present for issuers of securities in which the Fund invests, which could result in material adverse consequences for such issuers, and may cause the Fund's investment in such securities to lose value.

Index Construction Risk. A security included in the Index may not exhibit the characteristic or provide the specific exposure for which it was selected and consequently the Fund's holdings may not exhibit returns consistent with that characteristic or exposure.

Index Licensing Risk. It is possible that the license under which the Adviser or the Fund is permitted to replicate or otherwise use the Index will be terminated or may be disputed, impaired or cease to remain in effect. In such a case, the Adviser may be required to replace the Index with another index which it considers to be appropriate in light of the investment strategy of the Fund. The use of any such substitute index may have an adverse impact on the Fund's performance. In the event that the Adviser is unable to identify a suitable replacement for the Index, it may determine to terminate the Fund.

Money Market Risk. An investment in a money market fund is not a deposit of any bank and is not insured or guaranteed by the FDIC or any other government agency. Certain money market funds seek to preserve the value of their shares at $1.00 per share, although there can be no assurance that they will do so, and it is possible to lose money by investing in such a money market fund. A major or unexpected change in interest rates or a decline in the credit quality of an issuer or entity providing credit support, an inactive trading market for money market instruments, or adverse market, economic, industry, political, regulatory, geopolitical, and other conditions could cause the share price of such a money market fund to fall below $1.00. It is possible that such a money market fund will issue and redeem shares at $1.00 per share at times when the fair value of the money market fund's portfolio per share is more or less than $1.00. None of State Street Corporation, State Street, State Street Global Advisors (“SSGA”), SSGA FM or their affiliates (“State Street Entities”) guarantee the value of an investment in a money market fund at $1.00 per share. Investors should have no expectation of capital support to a money market fund from State Street Entities. Other money market funds price and transact at a “floating” NAV that will fluctuate along with changes in the market-based value of fund assets. Shares sold utilizing a floating NAV may be worth more or less than their original purchase price. Recent changes in the regulation of money market funds may affect the operations and structures of money market funds. A money market fund may be permitted or required to impose redemption fees or to impose limitations on redemptions during periods of high illiquidity in the markets for the investments held by it.

Portfolio Turnover Risk. The Fund may engage in frequent trading of its portfolio securities. Fund turnover generally involves a number of direct and indirect costs and expenses to the Fund, including, for example, brokerage commissions, dealer mark-ups and bid/asked spreads, and transaction costs on the sale of securities and reinvestment in other securities. The costs related to increased portfolio turnover may have the effect of reducing the Fund's investment return, and the sale of securities by the Fund may result in the realization of taxable capital gains, including short-term capital gains. The Fund may engage in significant trading of its portfolio securities in connection with Index rebalancing. Frequent or significant trading may cause the Fund to incur additional transaction costs and experience different tax consequences in comparison to an ETF that does not engage in frequent trading.

Securities Lending Risk. The Fund may lend portfolio securities in an amount not to exceed 40% of the value of its net assets. For these purposes, net assets shall exclude the value of all assets received as collateral for the loan. Such loans may be terminated at any time. Any such loans must be continuously secured by collateral maintained on a current basis in an amount at least equal to the market value of the securities loaned by the Fund, marked to market each trading day. In a loan transaction, as compensation for lending its securities, the Fund will receive a portion of the dividends or interest accrued on the securities held as collateral or, in the case of cash collateral, a portion of the income from the investment of such cash. In addition, the Fund will receive the amount of all dividends, interest and other distributions on the loaned securities. However, the borrower has the right to vote the loaned securities. The Fund will call loans to vote proxies if a material issue affecting the investment is to be voted upon. Efforts to recall such securities promptly may be unsuccessful, especially for foreign securities or thinly traded securities, and may involve expenses to the Fund. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. Should the borrower of the securities fail financially, the Fund may experience delays in recovering the securities or exercising its rights in the collateral. Loans are made only to borrowers that are deemed by the securities lending agent to be of good financial standing. In a loan

Table of Contents

transaction, the Fund will also bear the risk of any decline in value of securities provided as collateral or acquired with cash collateral. The Fund will attempt to minimize this risk by limiting the investment of cash collateral to high quality instruments of short maturity either directly on behalf of the lending Fund or through one or more joint accounts or funds, which may include those managed by the Adviser. To the extent the collateral provided or investments made with cash collateral differ from securities included in the Index, such collateral or investments may have a greater risk of loss than the securities included in the Index. In addition, the Fund will be subject to the risk that any income generated by lending its securities or reinvesting cash collateral is lower than any fees the Fund has agreed to pay a borrower. The Adviser will take into account the tax impact to shareholders of substitute payments for dividends when overseeing the Fund's securities lending activity.

Trading Issues. Although Fund Shares are listed for trading on the Exchange and may be listed or traded on U.S. and non-U.S. stock exchanges other than the Exchange, there can be no assurance that an active trading market for the Fund Shares will develop or be maintained. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to Exchange “circuit breaker” rules. Similar to the shares of operating companies listed on a stock exchange, Fund Shares may be sold short and are therefore subject to the risk of increased volatility in the trading price of the Fund's shares. While the Fund expects that the ability of Authorized Participants to create and redeem Fund Shares at net asset value should be effective in reducing any such volatility, there is no guarantee that it will eliminate the volatility associated with such short sales. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged or that Fund Shares will trade with any volume, or at all, on any stock exchange.

Management

Investment Adviser

SSGA FM serves as the investment adviser to the Fund and, subject to the oversight of the Board, is responsible for the investment management of the Fund. The Adviser provides an investment management program for the Fund and manages the investment of the Fund's assets. The Adviser is a wholly-owned subsidiary of State Street Global Advisors, Inc., which itself is a wholly-owned subsidiary of State Street Corporation. The Adviser is registered with the SEC under the Investment Advisers Act of 1940, as amended. The Adviser and certain other affiliates of State Street Corporation make up SSGA. SSGA is one of the world's largest institutional money managers and the investment management arm of State Street Corporation. As of June 30, 2021, the Adviser managed approximately $[ ] billion in assets and SSGA managed approximately $[ ] trillion in assets. The Adviser's principal business address is One Iron Street, Boston, Massachusetts 02210.

For the services provided to the Fund under the Investment Advisory Agreement, for the fiscal year ended June 30, 2021, the Fund paid the Adviser the annual fees based on a percentage of the Fund's average daily net assets as set forth below:

SPDR ICE Preferred Securities ETF

[0.45]%

From time to time, the Adviser may waive all or a portion of its management fee. [The Adviser has contractually agreed to waive a portion of its management fee and/or reimburse expenses in an amount equal to any acquired fund fees and expenses (excluding holdings in acquired funds for cash management purposes, if any) for the Fund until October 31, 2022. This waiver and/or reimbursement does not provide for the recoupment by the Adviser of any amounts waived or reimbursed. This waiver and/or reimbursement may not be terminated prior to October 31, 2022 except with the approval of the Board.] The Adviser pays all expenses of the Fund other than the management fee, brokerage expenses, taxes, interest, fees and expenses of the Independent Trustees (including any Trustee's counsel fees), litigation expenses, acquired fund fees and expenses and other extraordinary expenses.

A discussion regarding the Board's consideration of the Investment Advisory Agreement is provided in the Fund's Annual Report to Shareholders for the period ended June 30, 2021.

SSGA FM, as the investment adviser for the Fund, may hire one or more sub-advisers to oversee the day-to-day investment activities of the Fund. The sub-advisers are subject to oversight by the Adviser. The Adviser and SPDR Series Trust (the “Trust”) have received an exemptive order from the SEC that permits the Adviser, with the approval of

Table of Contents

the Independent Trustees of the Trust, to retain and amend existing sub-advisory agreements with unaffiliated investment sub-advisers for the Fund without submitting the sub-advisory agreement to a vote of the Fund's shareholders. The Trust will notify shareholders in the event of any change in the identity of such sub-adviser or sub-advisers. The Adviser has ultimate responsibility for the investment performance of the Fund due to its responsibility to oversee each sub-adviser and recommend their hiring, termination and replacement. The Adviser is not required to disclose fees paid to any unaffiliated sub-adviser retained pursuant to the order. Approval by Fund shareholders is required before any authority granted under the exemptive order may be exercised.

Portfolio Managers.
The Adviser manages the Fund using a team of investment professionals. The team approach is used to create an environment that encourages the flow of investment ideas. The portfolio managers within the team work together in a cohesive manner to develop and enhance techniques that drive the investment process for the investment strategy. This approach requires portfolio managers to share a variety of responsibilities including investment strategy and analysis while retaining responsibility for the implementation of the strategy within any particular portfolio. The approach also enables the team to draw upon the resources of other groups within SSGA. The portfolio management team is overseen by the SSGA Investment Committee.

The professionals primarily responsible for the day-to-day management of the Fund are Michael Feehily, Karl Schneider and Amy Scofield.

Additional Purchase and Sale Information

Fund Shares are listed for secondary trading on the Exchange and individual Fund Shares may only be purchased and sold in the secondary market through a broker-dealer. The secondary markets are closed on weekends and also are generally closed on the following holidays: New Year's Day, Dr. Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day (observed), Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Exchange may close early on the business day before certain holidays and on the day after Thanksgiving Day. Exchange holiday schedules are subject to change without notice. If you buy or sell Fund Shares in the secondary market, you will pay the secondary market price for Fund Shares. In addition, you may incur customary brokerage commissions and charges and may pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction.

The trading prices of Fund Shares will fluctuate continuously throughout trading hours based on market supply and demand rather than the Fund's net asset value, which is calculated at the end of each business day. Fund Shares will trade on the Exchange at prices that may be above (i.e., at a premium) or below (i.e., at a discount), to varying degrees, the daily net asset value of Fund Shares. The trading prices of Fund Shares may deviate significantly from the Fund's net asset value during periods of market volatility. Given, however, that Fund Shares can be issued and redeemed daily in Creation Units, the Adviser believes that large discounts and premiums to net asset value should not be sustained over long periods.

The Exchange will disseminate, every fifteen seconds during the regular trading day, an indicative optimized portfolio value (“IOPV”) relating to the Fund. The IOPV calculations are estimates of the value of the Fund's net asset value per Fund Share. Premiums and discounts between the IOPV and the market price may occur. This should not be viewed as a “real-time” update of the net asset value per Fund Share. The IOPV is based on the current market value of the published basket of portfolio securities and/or cash required to be deposited in exchange for a Creation Unit and does not necessarily reflect the precise composition of the Fund's actual portfolio at a particular point in time. Moreover, the IOPV is generally determined by using current market quotations and/or price quotations obtained from broker-dealers and other market intermediaries and valuations based on current market rates. The IOPV may not be calculated in the same manner as the NAV, which (i) is computed only once a day, (ii) unlike the calculation of the IOPV, takes into account Fund expenses, and (iii) may be subject, in accordance with the requirements of the 1940 Act, to fair valuation at different prices than those used in the calculations of the IOPV. The IOPV price is based on quotes and closing prices from the securities' local market converted into U.S. dollars at the current currency rates and may not reflect events that occur subsequent to the local market's close. Therefore, the IOPV may not reflect the best possible valuation of the Fund's current portfolio. Neither the Fund nor the Adviser or any of their affiliates are involved in, or responsible for, the calculation or dissemination of such IOPVs and make no warranty as to their accuracy.

The Fund does not impose any restrictions on the frequency of purchases and redemptions; however, the Fund reserves the right to reject or limit purchases at any time as described in the SAI. When considering that no restriction or policy was necessary, the Board evaluated the risks posed by market timing activities, such as whether frequent purchases and redemptions would interfere with the efficient implementation of the Fund's investment strategy, or whether they would cause the Fund to experience increased transaction costs. The Board considered that, unlike traditional mutual funds, Fund Shares are issued and redeemed only in large quantities of shares known as Creation Units, available only from the Fund directly, and that most trading in the Fund occurs on the Exchange at prevailing market prices and does not involve the Fund directly. Given this structure, the Board determined that it is unlikely that (a) market timing would be attempted by the Fund's shareholders or (b) any attempts to market time the Fund by shareholders would result in negative impact to the Fund or its shareholders.

Distributions

Dividends and Capital Gains. As a Fund shareholder, you are entitled to your share of the Fund's income and net realized gains on its investments. The Fund pays out substantially all of its net earnings to its shareholders as “distributions.”

The Fund may earn income dividends from stocks, interest from debt securities and, if participating, securities lending income. These amounts, net of expenses and taxes (if applicable), are passed along to Fund shareholders as “income dividend distributions.” The Fund will generally realize short-term capital gains or losses whenever it sells or exchanges assets held for one year or less. Net short-term capital gains will generally be treated as ordinary income when distributed to shareholders. The Fund will generally realize long-term capital gains or losses whenever it sells or exchanges assets held for more than one year. Net capital gains (the excess of the Fund's net long-term capital gains over its net short-term capital losses) are distributed to shareholders as “capital gain distributions.”

Income dividend distributions, if any, for the Fund are generally distributed to shareholders semi-annually, but may vary significantly from period to period.

Net capital gains for the Fund are distributed at least annually. Dividends may be declared and paid more frequently or at any other time to improve Index tracking or to comply with the distribution requirements of the Code. The Fund intends to distribute at least annually amounts representing the full dividend yield net of expenses on the underlying investment securities as if the Fund owned the underlying investment securities for the entire dividend period. As a result, some portion of each distribution may result in a return of capital. You will be notified regarding the portion of the distribution which represents a return of capital.

Distributions in cash may be reinvested automatically in additional whole Fund Shares only if the broker through whom you purchased Fund Shares makes such option available. Distributions which are reinvested will nevertheless be taxable to the same extent as if such distributions had not been reinvested.

Portfolio Holdings Disclosure

The Fund's portfolio holdings disclosure policy is described in the SAI. In addition, the identities and quantities of the securities held by the Fund are disclosed on the Fund's website.

Additional Tax Information

The following discussion is a summary of some important U.S. federal income tax considerations generally applicable to an investment in the Fund. Your investment in the Fund may have other tax implications. Please consult your tax advisor about federal, state, local, foreign or other tax laws applicable to you. Investors, including non-U.S. investors, may wish to consult the SAI tax section for additional disclosure.

Taxes on Distributions. In general, your distributions are subject to federal income tax when they are paid, whether you take them in cash or reinvest them in the Fund. The income dividends and short-term capital gains distributions you receive from the Fund will be taxed as either ordinary income or qualified dividend income. Subject to certain limitations, dividends that are reported by the Fund as qualified dividend income are taxable to noncorporate shareholders at rates of up to 20%. Any distributions of the Fund's net capital gains are taxable as long-term capital gain regardless of how long you have owned Fund Shares. Long-term capital gains are generally taxed to noncorporate shareholders at rates of up to 20%. Distributions in excess of the Fund's current and accumulated earnings and profits are treated as a tax-free return of capital to the extent of your basis in the Fund's shares, and, in general, as capital gain thereafter.

In general, dividends may be reported by the Fund as qualified dividend income if they are attributable to qualified dividend income received by the Fund, which, in general, includes dividend income from taxable U.S. corporations and certain foreign corporations (i.e., certain foreign corporations incorporated in a possession of the United States or in certain countries with a comprehensive tax treaty with the United States, and certain other foreign corporations if the stock with respect to which the dividend is paid is readily tradable on an established securities market in the United States), provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. A dividend generally will not be treated as qualified dividend income if the dividend is received with respect to any share of stock held by the Fund for fewer than 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share

Table of Contents

becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, for fewer than 91 days during the 181-day period beginning 90 days before such date. These holding period requirements will also apply to your ownership of Fund Shares. Holding periods may be suspended for these purposes for stock that is hedged. Additionally, income derived in connection with the Fund's securities lending activities will not be treated as qualified dividend income.

U.S. individuals with income exceeding specified thresholds are subject to a 3.8% Medicare contribution tax on all or a portion of their “net investment income,” which includes taxable interest, dividends and certain capital gains (generally including capital gain distributions and capital gains realized upon the sale of Fund Shares). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts.

Certain tax-exempt educational institutions will be subject to a 1.4% tax on net investment income. For these purposes, certain dividends and capital gain distributions, and certain gains from the disposition of Fund Shares (among other categories of income), are generally taken into account in computing a shareholder's net investment income.

If you lend your Fund Shares pursuant to securities lending arrangements you may lose the ability to treat Fund dividends (paid while the Fund Shares are held by the borrower) as qualified dividend income. You should consult your financial intermediary or tax advisor to discuss your particular circumstances.

Distributions paid in January, but declared by the Fund in October, November or December of the previous year, payable to shareholders of record in such a month, may be taxable to you in the calendar year in which they were declared. The Fund will inform you of the amount of your ordinary income dividends, qualified dividend income and capital gain distributions shortly after the close of each calendar year.

A distribution will reduce the Fund's net asset value per Fund Share and may be taxable to you as ordinary income or capital gain even though, from an investment standpoint, the distribution may constitute a return of capital.

Derivatives and Other Complex Securities. The Fund may invest in complex securities. These investments may be subject to numerous special and complex rules. These rules could affect whether gains and losses recognized by the Fund are treated as ordinary income or capital gain, accelerate the recognition of income to the Fund and/or defer the Fund's ability to recognize losses. In turn, these rules may affect the amount, timing or character of the income distributed to you by the Fund. You should consult your personal tax advisor regarding the application of these rules.

Foreign Currency Transactions. The Fund's transactions in foreign currencies, foreign currency denominated debt obligations and certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the extent such income or loss results from fluctuations in the value of the foreign currency concerned.

Foreign Income Taxes. Investment income received by the Fund from sources within foreign countries may be subject to foreign income taxes withheld at the source. The United States has entered into tax treaties with many foreign countries which may entitle the Fund to a reduced rate of such taxes or exemption from taxes on such income. It is impossible to determine the effective rate of foreign tax for the Fund in advance since the amount of the assets to be invested within various countries is not known. If more than 50% of the total assets of the Fund at the close of its taxable year consist of certain foreign stocks or securities, the Fund may elect to “pass through” to you certain foreign income taxes (including withholding taxes) paid by the Fund. If the Fund in which you hold Fund Shares makes such an election, you will be considered to have received as an additional dividend your share of such foreign taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your federal income tax. No deduction for such taxes will be permitted to individuals in computing their alternative minimum tax liability. If the Fund does not so elect, the Fund will be entitled to claim a deduction for certain foreign taxes incurred by the Fund. Under certain circumstances, if the Fund receives a refund of foreign taxes paid in respect of a prior year, the value of Fund Shares could be affected or any foreign tax credits or deductions passed through to shareholders in respect of the Fund's foreign taxes for the current year could be reduced.

Real Estate Investments. Non-U.S. persons are generally subject to U.S. tax on a disposition of a “United States real property interest” (a “USRPI”). Gain on such a disposition is generally referred to as “FIRPTA gain.” The Code provides a look-through rule for distributions of so-called FIRPTA gain by the Fund if certain requirements are met. If the look-through rule applies, certain distributions attributable to income received by the Fund, e.g., from U.S. REITs,

Table of Contents

may be treated as gain from the disposition of a USRPI, causing distributions to be subject to U.S. withholding tax at rates of up to 21%, and requiring non-U.S. investors to file nonresident U.S. income tax returns. Also, gain may be subject to a 30% branch profits tax in the hands of a foreign stockholder that is treated as a corporation for federal income tax purposes. Under certain circumstances, Shares may qualify as USRPIs, which could result in 15% withholding on certain distributions and gross redemption proceeds paid to certain non-U.S. shareholders.

For tax years beginning after December 31, 2017 and before January 1, 2026, a noncorporate taxpayer is generally eligible for a deduction of up to 20% of the taxpayer's “qualified REIT dividends.” If the Fund receives dividends (other than capital gain dividends) in respect of REIT shares, the Fund may report its own dividends as eligible for the 20% deduction, to the extent the Fund's income is derived from such qualified REIT dividends, as reduced by allocable Fund expenses. In order for the Fund's dividends to be eligible for this deduction when received by a noncorporate shareholder, the Fund must meet certain holding period requirements with respect to the REIT shares on which the Fund received the eligible dividends, and the noncorporate shareholder must meet certain holding period requirements with respect to the Fund Shares.

Taxes on Exchange-Listed Share Sales. Any capital gain or loss realized upon a sale of Fund Shares is generally treated as long-term capital gain or loss if Fund Shares have been held for more than one year and as short-term capital gain or loss if Fund Shares have been held for one year or less, except that any capital loss on the sale of Fund Shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to the Fund Shares.

Taxes on Creations and Redemptions of Creation Units. A person who exchanges securities for Creation Units generally will recognize a gain or loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and the exchanger's aggregate basis in the securities surrendered plus any cash paid for the Creation Units. A person who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanger's basis in the Creation Units and the aggregate market value of the securities and the amount of cash received. The Internal Revenue Service (the “IRS”), however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position. Persons exchanging securities should consult their own tax advisor with respect to whether wash sale rules apply and when a loss might be deductible.

Under current federal tax laws, any capital gain or loss realized upon a redemption (or creation) of Creation Units is generally treated as long-term capital gain or loss if the Fund Shares (or securities surrendered) have been held for more than one year and as a short-term capital gain or loss if the Fund Shares (or securities surrendered) have been held for one year or less.

If you create or redeem Creation Units, you will be sent a confirmation statement showing how many Fund Shares you purchased or sold and at what price.

The Trust on behalf of the Fund has the right to reject an order for Creation Units if the purchaser (or a group of purchasers) would, upon obtaining the Fund Shares so ordered, own 80% or more of the outstanding shares of the Fund and if, pursuant to Section 351 of the Code, the Fund would have a basis in the securities different from the market value of the securities on the date of deposit. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination. If the Trust does issue Creation Units to a purchaser (or a group of purchasers) that would, upon obtaining the Fund Shares so ordered, own 80% or more of the outstanding shares of the Fund, the purchaser (or group of purchasers) will not recognize gain or loss upon the exchange of securities for Creation Units.

If the Fund redeems Creation Units in cash, it may bear additional costs and recognize more capital gains than it would if it redeems Creation Units in-kind.

Certain Tax-Exempt Investors. The Fund, if investing in certain limited real estate investments and other publicly traded partnerships, may be required to pass through certain “excess inclusion income” and other income as “unrelated business taxable income” (“UBTI”). Prior to investing in the Fund, tax-exempt investors sensitive to UBTI should consult their tax advisors regarding this issue and IRS pronouncements addressing the treatment of such income in the hands of such investors.

Table of Contents

Investments In Certain Foreign Corporations. The Fund may invest in foreign entities classified as passive foreign investment companies or “PFICs” or controlled foreign corporations or “CFCs” under the Code. PFIC and CFC investments are subject to complex rules that may under certain circumstances adversely affect the Fund. Accordingly, investors should consult their own tax advisors and carefully consider the tax consequences of PFIC and CFC investments by the Fund before making an investment in the Fund. Fund dividends attributable to dividends received from PFICs generally will not be treated as qualified dividend income. Additional information pertaining to the potential tax consequences to the Fund, and to the shareholders, from the Fund's potential investment in PFICs and CFCs can be found in the SAI.

Non-U.S. Investors. Ordinary income dividends paid by the Fund to shareholders who are non-resident aliens or foreign entities will generally be subject to a 30% U.S. withholding tax (other than distributions reported by the Fund as interest-related dividends and short-term capital gain dividends), unless a lower treaty rate applies or unless such income is effectively connected with a U.S. trade or business. In general, the Fund may report interest-related dividends to the extent of its net income derived from U.S.-source interest, and the Fund may report short-term capital gain dividends to the extent its net short-term capital gain for the taxable year exceeds its net long-term capital loss. Gains on the sale of Fund Shares and dividends that are, in each case, effectively connected with the conduct of a trade or business within the U.S. will generally be subject to U.S. federal net income taxation at regular income tax rates. Non-U.S. shareholders that own, directly or indirectly, more than 5% of the Fund's shares are urged to consult their own tax advisors concerning special tax rules that may apply to their investment.

Unless certain non-U.S. entities that hold Fund Shares comply with IRS requirements that will generally require them to report information regarding U.S. persons investing in, or holding accounts with, such entities, a 30% withholding tax may apply to distributions payable to such entities. A non-U.S. shareholder may be exempt from the withholding described in this paragraph under an applicable intergovernmental agreement between the U.S. and a foreign government, provided that the shareholder and the applicable foreign government comply with the terms of such agreement.

Backup Withholding. The Fund will be required in certain cases to withhold (as “backup withholding”) on amounts payable to any shareholder who (1) has provided the Fund either an incorrect tax identification number or no number at all, (2) is subject to backup withholding by the IRS for failure to properly report payments of interest or dividends, (3) has failed to certify to the Fund that such shareholder is not subject to backup withholding, or (4) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). The backup withholding rate is currently 24%. Backup withholding will not be applied to payments that have been subject to the 30% withholding tax on shareholders who are neither citizens nor permanent residents of the United States.

Other Tax Issues. The Fund may be subject to tax in certain states where the Fund does business (or is treated as doing business as a result of its investments). Furthermore, in those states which have income tax laws, the tax treatment of the Fund and of Fund shareholders with respect to distributions by the Fund may differ from federal tax treatment.

The foregoing discussion summarizes some of the consequences under current federal income tax law of an investment in the Fund. It is not a substitute for personal tax advice. Consult your personal tax advisor about the potential tax consequences of an investment in the Fund under all applicable tax laws.

General Information

The Trust was organized as a Massachusetts business trust on June 12, 1998. If shareholders of any Fund are required to vote on any matters, shareholders are entitled to one vote for each Fund Share they own. Annual meetings of shareholders will not be held except as required by the 1940 Act and other applicable law. See the SAI for more information concerning the Trust's form of organization.

Management and Organization

The Fund is a separate series of the Trust, which is an open-end registered management investment company.

For purposes of the 1940 Act, Fund Shares are issued by the respective series of the Trust and the acquisition of Fund Shares by investment companies is subject to the restrictions of Section 12(d)(1) of the 1940 Act.

Table of Contents

The Trust has received exemptive relief from Section 12(d)(1) to allow registered investment companies to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions as set forth in an SEC exemptive order issued to the Trust, including that such investment companies enter into an agreement with the Trust. This order will be rescinded by the SEC on January 19, 2022. However, effective January 19, 2021, new Rule 12d1-4 permits other investment companies to invest in the Fund beyond the limits in Section 12(d)(1), subject to similar conditions.

From time to time, the Fund may advertise yield and total return figures. Yield is a historical measure of dividend income, and total return is a measure of past dividend income (assuming that it has been reinvested) plus capital appreciation. Neither yield nor total return should be used to predict the future performance of the Fund.

Morgan, Lewis & Bockius LLP serves as counsel to the Trust, including the Fund. [ ] serves as the independent registered public accounting firm and will audit the Fund's financial statements annually.

Financial Highlights

These financial highlight tables are intended to help you understand the Fund's financial performance for the past five fiscal years. Certain information reflects the performance results for a single Fund Share. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). This information has been audited by [ ], the Trust's independent registered public accounting firm, whose report, along with the Fund's financial highlights and financial statements, is included in the annual report to shareholders, which is available upon request. Any references to Notes in these financial highlight tables refer to the “Notes to Financial Statements” section of the Fund's financial statements, and the financial information included in these tables should be read in conjunction with the financial statements incorporated by reference in the SAI.

The Trust is an open-end management investment company, registered under the Investment Company Act of 1940, as amended (the “1940 Act”), consisting of multiple investment series, including the Equity ETFs and Fixed Income ETFs (each, a “Fund” and, collectively, the “Funds”). The Trust was organized as a Massachusetts business trust on June 12, 1998. The offering of each Fund’s shares (“Shares”) is registered under the Securities Act of 1933, as amended (the “Securities Act”). The investment objective of each Fund is to provide investment results that, before fees and expenses, correspond generally to the total return (or in the case of the Fixed Income ETFs, the price and yield performance) of a specified market index (each an “Index” and together the “Indexes”). SSGA Funds Management, Inc. serves as the investment adviser for each Fund (“SSGA FM” or the “Adviser”) and certain funds are sub-advised by a sub-adviser as further described herein (each, a “Sub-Adviser”). To the extent that a reference in this SAI refers to the “Adviser,” such reference should also be read to refer to the Sub-Adviser where the context requires.

Each Fund offers and issues Shares at their net asset value (sometimes referred to herein as “NAV”) only in aggregations of a specified number of Shares (each, a “Creation Unit”). Each Fund generally offers and issues Shares either in exchange for (i) a basket of securities designated by the Fund (“Deposit Securities”) together with the deposit of a specified cash payment (“Cash Component”) or (ii) a cash payment equal in value to the Deposit Securities (“Deposit Cash”) together with the Cash Component. The primary consideration accepted by a Fund (i.e., Deposit Securities or Deposit Cash) is set forth under “Purchase and Redemption of Creation Units” later in this SAI. The Trust reserves the right to permit or require the substitution of a “cash in lieu” amount to be added to the Cash Component to replace any Deposit Security and reserves the right to permit or require the substitution of Deposit Securities in lieu of Deposit Cash (subject to applicable legal requirements). The Shares have been approved for listing and secondary trading on a national securities exchange (the “Exchange”). The Shares will trade on the Exchange at market prices. These prices may differ from the Shares’ net asset values. The Shares are also redeemable only in Creation Unit aggregations, and generally in exchange either for (i) portfolio securities and a specified cash payment or (ii) cash (subject to applicable legal requirements).

Shares may be issued in advance of receipt of Deposit Securities subject to various conditions including a requirement to maintain on deposit with the Trust cash at least equal to a specified percentage of the market value of the missing Deposit Securities as set forth in the Participant Agreement (as defined below). See “Purchase and Redemption of Creation Units.” The Trust may impose a transaction fee for each creation or redemption. In all cases, such fees will be limited in accordance with the requirements of the U.S. Securities and Exchange Commission (“SEC”) applicable to management investment companies offering redeemable securities. In addition to the fixed creation or redemption transaction fee, an additional transaction fee of up to three times the fixed creation or redemption transaction fee and/or an additional variable charge may apply.

Each Fund may invest in the following types of investments, consistent with its investment strategies and objective. Please see a Fund’s Prospectus for additional information regarding its principal investment strategies.

Each Fund (except the SPDR Portfolio S&P 500 Growth ETF, SPDR S&P 1500 Momentum Tilt ETF, SPDR S&P 1500 Value Tilt ETF, SPDR S&P Kensho Clean Power ETF, SPDR S&P Kensho Final Frontiers ETF, SPDR S&P Kensho Future Security ETF, SPDR S&P Kensho Intelligent Structures ETF, SPDR S&P Kensho New Economies Composite ETF, SPDR S&P Kensho Smart Mobility ETF, SPDR S&P Metals & Mining ETF, and SPDR Bloomberg Barclays Emerging Markets USD Bond ETF) is classified as a “diversified” investment company under the 1940 Act. Under the 1940 Act, a diversified investment company, as to 75% of its total assets, may not purchase securities of any issuer (other than securities issued or guaranteed by the U.S. government, its agents or instrumentalities or securities of other investment companies) if, as a result, more than 5% of its total assets would be invested in the securities of such issuer, or more than 10% of the issuer’s outstanding voting securities would be held by the investment company. A “non-diversified” classification means that a Fund is not limited by the 1940 Act with regard to the percentage of its assets that may be invested in the securities of a single issuer. This means that a Fund may invest a greater portion of its assets in the securities of a single issuer than a diversified fund. The securities of a particular issuer may constitute a greater portion of an Index of a Fund and, therefore, the securities may constitute a greater portion of the Fund’s portfolio. This may have an adverse effect on the Fund’s performance or subject the Fund’s Shares to greater price volatility than more diversified investment companies.

Each Fund seeks to track the performance of its respective Index. The composition of each Index may fluctuate between non-diversified and diversified solely due to changes in weightings of one or more Index components. As a result, a Fund’s diversification status also may fluctuate between non-diversified and diversified depending on the composition of, and to approximately the same extent as, its respective Index. To the extent a diversified equity Fund becomes non-diversified due solely to changes in the composition of its Index, it will not seek shareholder approval if and when the Fund shifts from diversified to non-diversified.

Each Fund (whether diversified or non-diversified for purposes of the 1940 Act) intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a “regulated investment company” (“RIC”) for purposes of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and to relieve the Fund of any liability for federal income tax to the extent that its earnings are distributed to shareholders. Compliance with the diversification requirements of the Internal Revenue Code may severely limit the investment flexibility of a Fund and may make it less likely that the Fund will meet its investment objective.

Asset-backed securities are securities backed by installment contracts, credit-card receivables or other assets. Commercial mortgage-backed securities are securities backed by commercial real estate properties. Both asset-backed and commercial mortgage-backed securities represent interests in “pools” of assets in which payments of both interest and principal on the securities are made on a regular basis. The payments are, in effect, “passed through” to the holder of the securities (net of any fees paid to the issuer or guarantor of the securities). The average life of asset-backed and commercial mortgage-backed securities varies with the maturities of the underlying instruments and, as a result of prepayments, can often be less than the original maturity of the assets underlying the securities. For this and other reasons, an asset-backed and commercial mortgage-backed security’s stated maturity may be shortened, and the security’s total return may be difficult to predict precisely.

A bond is an interest-bearing security issued by a company, governmental unit or, in some cases, a non-U.S. entity. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond’s face value) periodically or on a specified maturity date; provided, however, a zero coupon bond pays no interest to its holder during its life. The value of a zero coupon bond to a Fund consists of the difference between such bond’s face value at the time of maturity and the price for which it was acquired, which may be an amount significantly less than its face value (sometimes referred to as a “deep discount” price).

An issuer may have the right to redeem or “call” a bond before maturity, in which case the investor may have to reinvest the proceeds at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed rate bond’s yield (income as a percent of the bond’s current value) may differ from its coupon rate as its value rises or falls. Fixed rate bonds generally are also subject to inflation risk, which is the risk that the value of the bond or income from the bond will be worth less in the future as inflation decreases the value of money. This could mean that, as inflation increases, the “real” value of the assets of a Fund holding fixed rate bonds can decline, as can the value of the Fund’s distributions. Other types of bonds bear income at an interest rate that is adjusted periodically. Because of their adjustable interest rates, the value of “floating-rate” or “variable-rate” bonds fluctuates much less in response to market interest rate movements than the value of fixed rate bonds. A Fund may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on a corporation’s earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (also backed by specified collateral).

The investment return of corporate bonds reflects interest on the bond and changes in the market value of the bond. The market value of a corporate bond may be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the market place. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by such a security.

Commercial paper consists of short-term, promissory notes issued by banks, corporations and other entities to finance short-term credit needs. These securities generally are discounted but sometimes may be interest bearing.

Risks inherent in investing in equity securities include the risk that the financial condition of issuers may become impaired or that the general condition of the stock market may deteriorate (either of which may cause a decrease in the value of a Fund’s portfolio securities and therefore a decrease in the value of Shares of the Fund). Common stock is susceptible to general stock market fluctuation and to volatile increases and decreases in value as market confidence and perceptions change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic or banking crises.

Holders of common stock incur more risk than holders of preferred stock and debt obligations because common stockholders, as owners of the issuer, have generally inferior rights to receive payments from the issuer in comparison with the rights of creditors of, or holders of debt obligations or preferred stock issued by, the issuer. Further, unlike debt securities which typically have a stated principal amount payable at maturity (whose value, however, will be subject to market fluctuations prior thereto), or preferred stock which typically has a liquidation preference and which may have stated optional or mandatory redemption provisions, common stock has neither a fixed principal amount nor a maturity. Common stock values are subject to market fluctuations as long as the common stock remains outstanding.

Each Fund will concentrate its investments in securities of issuers in the same industry as may be necessary to approximate the composition of the Fund’s underlying Index. The securities of issuers in particular industries may dominate the benchmark Index of a Fund and consequently a Fund’s investment portfolio. This may adversely affect a Fund’s performance or subject its Shares to greater price volatility than that experienced by less concentrated investment companies. The Trust’s general policy is to exclude securities of the U.S. government and its agencies or instrumentalities when measuring industry concentration.

In pursuing its objective, each Fund may hold the securities of a single issuer in an amount exceeding 10% of the market value of the outstanding securities of the issuer, subject to restrictions imposed by the Internal Revenue Code. In particular, as a Fund’s size grows and its assets increase, it will be more likely to hold more than 10% of the securities of a single issuer if the issuer has a relatively small public float as compared to other components in its benchmark Index.

CONSIDERATIONS REGARDING INVESTMENT IN MUNICIPAL SECURITIES ISSUED BY PUERTO RICO

Each Fund may invest in the Commonwealth of Puerto Rico (“Puerto Rico”) municipal bonds and, therefore, may be impacted by political, economic, or regulatory developments that affect issuers in Puerto Rico and their ability to pay principal and interest on their obligations. Puerto Rico, the fourth largest of the Caribbean islands, is located approximately 1,000 miles southeast of Miami, Florida. Puerto Rico’s constitutional status is that of a territory of the United States, and, pursuant to the territorial clause of the U.S. Constitution, the ultimate source of power over Puerto Rico is the U.S. Congress. Residents of Puerto Rico are citizens of the United States but do not vote in national elections.

Puerto Rico’s economy, historically dominated by government and manufacturing employment, has been in recession since 2006, and since 2008 has seen its Gross National Product (GNP) decline by 20%. High unemployment, weak job growth and natural disasters (discussed below) have contributed to historic outmigration of Puerto Rican residents. At its peak, Puerto Rico had a population of more than 3.8 million. Since then, more than 632,000 Puerto Ricans have left the country. In 2018 alone, the country experienced a 3.9% decline in population. It is expected that by 2025, the population will drop below 3 million.

Protracted economic decline and population losses have directly impacted Puerto Rico’s tax base and operating budget. Puerto Rico’s operating budget became structurally unbalanced during the 2008 recession and, as a result, the government began relying on deficit financing for annual operations. This borrowing led to a tremendous debt burden, which is very high in comparison to that of most states. Further, Puerto Rico issues debt under many different securities, but many of the security pledges are ultimately dependent on the island’s general fund, creating interdependency between credits.

In 2014, Puerto Rico’s then-Governor declared that Puerto Rico’s “debt is not payable” and Puerto Rico would no longer borrow to address annual budget deficits. Puerto Rico experienced its first debt default in 2015. On June 30, 2016, the Puerto Rico Oversight, Management and Economic Stability Act (“PROMESA”) was signed into law, aimed at helping Puerto Rico restructure its debt. Among other things, PROMESA established the Financial and Oversight Management Board (“FOMB”) to oversee Puerto Rico’s financial operations and provide a legal framework for debt restructuring. As required by PROMESA, Puerto Rico must submit fiscal plans to the FOMB. The fiscal plans are required to provide estimates of revenues and expenditures, ensure funding for essential public services, provide adequate funding pensions, eliminate any structural deficits, provide for a sustainable debt burden, and improve fiscal governance, accountability and internal controls. The fiscal plans must also include a debt sustainability analysis and provide for capital investments necessary to promote economic growth.

The first fiscal plan for Puerto Rico was certified by the FOMB in March 2017. By May 2017, the board had initiated a Title III, bankruptcy-like process for the general government, general obligation debt, the Puerto Rico Sales Tax Financing Corporation (COFINA), the Highways and Transportation Authority (HTA), and the Employee Retirement System (ERS). Implementation of the fiscal plan and the Title III court process were both underway when Puerto Rico was hit by a devastating natural disaster.

In September 2017, two successive hurricanes – Irma and Maria – caused severe damage to Puerto Rico. Hurricane Maria alone is estimated to have caused more than $100 billion in damage and caused a decline in GNP in the years following the storms. In June 2019, President Trump signed a $19 billion disaster relief bill, of which approximately $1 billion would be allocated to Puerto Rico. In addition, while Puerto Rico’s population has declined every year since 2013, the trend accelerated after the damage caused by Hurricanes Irma and Maria displaced residents. The damage caused by Hurricanes Irma and Maria has had, and is expected to continue to have, substantially adverse effects on Puerto Rico’s economy. In addition to diverting funds to relief and recovery efforts, Puerto Rico has experienced significant revenue loss as a result of decreased tourism and general business operations. Puerto Rico continues to recover and rebuild from the damage and it is not currently possible to predict the extent of the impact that Hurricanes Irma and Maria will have on Puerto Rico’s economy. The impact of the 2017 hurricanes, coupled with political upheaval and significant damage caused by earthquakes in 2019, significantly hampered the government and FOMB’s timeline and efforts to restructure Puerto Rico’s debt.

In February 2020, the FOMB announced a new consensual agreement with roughly 50% of Puerto Rico’s General Obligation (GO) and Public Building Authority (PBA) bondholders. The agreement significantly reduces debt service by cutting $35 billion of liabilities to just $10.7 billion. Pursuant to the agreement, GO and PBA bondholders would receive recoveries ranging from 65% to 75% based on a consideration of $10.1 billion in new bonds and $3.4 billion in cash.

The COVID-19 pandemic has significantly impacted Puerto Rico’s economy and delayed the bankruptcy process. The FOMB estimates $6.6 billion in damages over the next two years resulting from economic shrinkage of 11% in both fiscal years 2020 and 2021. The FOMB also estimates that Puerto Rico will receive a total of 350,000 unemployment claims (including claims from self-employed residents) related to the pandemic. The long-term effects the COVID-19 pandemic will have on Puerto Rico are currently unpredictable.

Convertible securities are bonds, debentures, notes, preferred stock or other securities that may be converted or exchanged (by the holder or by the issuer) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio. A convertible security may also be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. If a convertible security held by a Fund is called for redemption or conversion, the Fund could be required to tender it for redemption, convert it into the underlying common stock, or sell it to a third party.

Convertible securities generally have less potential for gain or loss than common stock. Convertible securities generally provide yields higher than the underlying common stock, but generally lower than comparable non-convertible securities. Because of this higher yield, convertible securities generally sell at a price above their “conversion value,” which is the current market value of the stock to be received upon conversion. The difference between this conversion value and the price of convertible securities will vary over time depending on changes in the value of the underlying common stock and interest rates. When the underlying common stock declines in value, convertible securities will tend not to decline to the same extent because of the interest or dividend payments and the repayment of principal at maturity for certain types of convertible securities. However, securities that are convertible other than at the option of the holder generally do not limit the potential for loss to the same extent as securities convertible at the option of the holder. When the underlying common stock rises in value, the value of convertible securities may also be expected to increase. At the same time, however, the difference between the market value of convertible securities and their conversion value will narrow, which means that the value of convertible securities will generally not increase to the same extent as the value of the underlying common stock. Because convertible securities may also be interest-rate sensitive, their value may increase as interest rates fall and decrease as interest rates rise. Convertible securities are also subject to credit risk, and are often lower-quality securities.

Each Fund may invest in other exchange-traded funds (“ETFs”, including ETFs managed by the Adviser). ETFs may be structured as investment companies that are registered under the 1940 Act, typically as open-end funds or unit investment trusts. These ETFs are generally based on specific domestic and foreign market securities indices. An “index-based ETF” seeks to provide investment results that match the performance of an index by holding in its portfolio either the contents of the index or a representative sample of the securities in the index. An “actively-managed ETF” invests in securities based on an adviser’s investment strategy. An “enhanced ETF” seeks to provide investment results that match a positive or negative multiple of the performance of an underlying index. In seeking to provide such results, an ETF and, in particular, an enhanced ETF, may engage in short sales of securities included in the underlying index and may invest in derivatives instruments, such as equity index swaps, futures contracts, and options on securities, futures contracts, and stock indices. Alternatively, ETFs may be structured as grantor trusts or other forms of pooled investment vehicles that are not registered or regulated under the 1940 Act. These ETFs typically hold commodities, precious metals, currency or other non-securities investments. ETFs, like mutual funds, have expenses associated with their operation, such as advisory and custody fees. When a Fund invests in an ETF, in addition to directly bearing expenses associated with its own operations, including

the brokerage costs associated with the purchase and sale of shares of the ETF, the Fund will bear a pro rata portion of the ETF’s expenses. In addition, it may be more costly to own an ETF than to directly own the securities or other investments held by the ETF because of ETF expenses. The risks of owning shares of an ETF generally reflect the risks of owning the underlying securities or other investments held by the ETF, although lack of liquidity in the market for the shares of an ETF could result in the ETF’s value being more volatile than the underlying securities or other investments.

Each Fund may conduct foreign currency transactions on a spot (i.e., cash) or forward basis (i.e., by entering into forward contracts to purchase or sell foreign currencies). Although foreign exchange dealers generally do not charge a fee for such conversions, they do realize a profit based on the difference between the prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency at one rate, while offering a lesser rate of exchange should the counterparty desire to resell that currency to the dealer. Forward contracts are customized transactions that generally require a specific amount of a currency to be delivered at a specific exchange rate on a specific date or range of dates in the future, although the Funds may also enter into non-deliverable currency forward contracts (“NDFs”) that contractually require the netting of the parties’ liabilities. Forwards, including NDFs, can have substantial price volatility. While foreign currency transactions on a spot and forward basis are exempt from the definition of “swap” under the Commodity Exchange Act (“CEA”), NDFs are not, and, thus, are subject to the jurisdiction of the Commodity Futures Trading Commission (“CFTC”). Forward contracts are generally traded in an interbank market directly between currency traders (usually large commercial banks) and their customers. The parties to a forward contract may agree to offset or terminate the contract before its maturity, or may hold the contract to maturity and complete the contemplated currency exchange. In the event that the parties to a forward contract agree to offset or terminate the contract before its maturity, the contract is no longer exempt from the definition of “swap” under the CEA and shall be treated as a swap. At the discretion of the Adviser, the Funds may enter into forward currency exchange contracts for hedging purposes to help reduce the risks and volatility caused by changes in foreign currency exchange rates, or to gain exposure to certain currencies in an effort to track the composition of the applicable Index. When used for hedging purposes, they tend to limit any potential gain that may be realized if the value of the Fund’s foreign holdings increases because of currency fluctuations.

Each Fund may invest up to 20% of its assets in derivatives, including exchange-traded futures on indices, exchange-traded futures on Treasuries or Eurodollars, U.S. exchange-traded or OTC put and call options contracts and exchange-traded or OTC swap transactions (including NDFs, interest rate swaps, total return swaps, excess return swaps, and credit default swaps). A Fund will segregate cash and/or appropriate liquid assets if required to do so by SEC or CFTC regulation or interpretation.

Futures and Options on Futures. Futures contracts generally provide for the future sale by one party and purchase by another party of a specified commodity or security at a specified future time and at a specified price. Index futures contracts are settled daily with a payment by one party to the other of a cash amount based on the difference between the level of the index specified in the contract from one day to the next. A futures contract on an index is an agreement pursuant to which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the index at the close of the last trading day of the contract and the price at which the index contract originally was written. Although the value of an index might be a function of the value of certain specified securities, physical delivery of these securities is not always made. A public market exists in futures contracts covering a number of indexes, as well as financial instruments, including, without limitation: U.S. Treasury bonds; U.S. Treasury notes; GNMA Certificates; three-month U.S. Treasury bills; 90-day commercial paper; bank certificates of deposit; Eurodollar certificates of deposit; the Australian Dollar; the Canadian Dollar; the British Pound; the Japanese Yen; the Swiss Franc; the Mexican Peso; and certain multinational currencies, such as the Euro. It is expected that other futures contracts will be developed and traded in the future. Futures contracts are standardized as to maturity date and underlying instrument and are traded on futures exchanges.

The Funds may purchase and write (sell) call and put options on futures. Options on futures give the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price upon expiration of, or at any time during the period of, the option. Upon exercise of a call option, the holder acquires a long position in the futures contract and the writer is assigned the opposite short position. In the case of a put option, the opposite is true.

A Fund is required to make a good faith margin deposit in cash or U.S. government securities (or other eligible collateral) with a broker or custodian to initiate and maintain open positions in futures contracts. A margin deposit is intended to assure completion of the contract (delivery or acceptance of the underlying commodity or payment of the cash settlement amount) if it is not terminated prior to the specified delivery date. Brokers may establish deposit requirements which are higher than the exchange minimums. Futures contracts are customarily purchased and sold on margin deposits which may range upward from less than 5% of the value of the contract being traded.

After a futures contract position is opened, the value of the contract is marked to market daily. If the futures contract price changes to the extent that the margin on deposit does not satisfy price changes, additional payments will be required. Conversely, change in the contract value may reduce the required margin, resulting in a repayment of excess margin to the contract holder. Variation margin payments are made to and from the futures broker for as long as the contract remains open. In such case, a Fund would expect to earn interest income on its margin deposits. Although some futures contracts call for making or taking delivery of the underlying commodity, generally these obligations are closed out prior to delivery by offsetting purchases or sales of matching futures contracts (involving the same exchange, underlying security or index and delivery month). If an offsetting purchase price is less than the original sale price, the Fund realizes a capital gain, or if it is more, the Fund realizes a capital loss. Conversely, if an offsetting sale price is more than the original purchase price, the Fund realizes a capital gain, or if it is less, the Fund realizes a capital loss. The transaction costs also must be included in these calculations.

Options. A Fund may purchase and sell put and call options. Such options may relate to particular securities and may or may not be listed on a national securities exchange and issued by the Options Clearing Corporation. Options trading is a highly specialized activity that entails greater than ordinary investment risk. Options on particular securities may be more volatile than the underlying securities, and therefore, on a percentage basis, an investment in options may be subject to greater fluctuation than an investment in the underlying securities themselves.

Short Sales “Against the Box.” The Funds may engage in short sales “against the box.” In a short sale against the box, a Fund agrees to sell at a future date a security that it either contemporaneously owns or has the right to acquire at no extra cost. If the price of the security has declined at the time the Fund is required to deliver the security, the Fund will benefit from the difference in the price. If the price of the security has increased, the Fund will be required to pay the difference.

Swap Transactions. Each Fund may enter into swap transactions, including interest rate swap, credit default swap, NDF, and total return swap transactions. Swap transactions are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make payments to the first party based on the return of a different specified rate, index or asset. Swap transactions will usually be done on a net basis, i.e., where the two parties make net payments with a Fund receiving or paying, as the case may be, only the net amount of the two payments. The net amount of the excess, if any, of a Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis and an amount of cash or equivalents having an aggregate value at least equal to the accrued excess is maintained by the Fund. Swaps may be used in conjunction with other instruments to offset interest rate, currency or other underlying risks. For example, interest rate swaps may be offset with “caps,” “floors” or “collars.” A “cap” is essentially a call option which places a limit on the amount of floating rate interest that must be paid on a certain principal amount. A “floor” is essentially a put option which places a limit on the minimum amount that would be paid on a certain principal amount. A “collar” is essentially a combination of a long cap and a short floor where the limits are set at different levels.

The use of swap transactions by a Fund entails certain risks, which may be different from, or possibly greater than, the risks associated with investing directly in the securities and other investments that are the referenced asset for the swap agreement. Swaps are highly specialized instruments that require investment techniques, risk analyses, and tax planning different from those associated with stocks, bonds, and other traditional investments. The use of a swap requires an understanding not only of the referenced asset, reference rate, or index, but also of the swap itself, without the benefit of observing the performance of the swap under all the possible market conditions. Because some swap transactions have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the swap itself. Certain swaps have the potential for unlimited loss, regardless of the size of the initial investment.

Bilateral OTC transactions differ from exchange-traded or cleared derivatives transactions in several respects. Bilateral OTC transactions are transacted directly with dealers and not with a clearing corporation. Without the availability of a clearing corporation, bilateral OTC transaction pricing is normally done by reference to information from market makers and/or available index data, which information is carefully monitored by the Adviser and verified in appropriate cases. As bilateral OTC transactions are entered into directly with a dealer, there is a risk of nonperformance by the dealer as a result of its insolvency or otherwise. Under recently-adopted regulations by the CFTC and federal banking regulators (“Margin Rules”), a Fund is required to post collateral (known as variation margin) to cover the mark-to-market exposure in respect of its uncleared swaps. The Margin Rules also mandate that collateral in the form of initial margin be posted to cover potential future exposure attributable to uncleared swap transactions. In the event a Fund is required to post collateral in the form of initial margin or variation margin in respect of its uncleared swap transactions, all such collateral will be posted with a third party custodian pursuant to a triparty custody agreement between the Fund, its dealer counterparty and an unaffiliated custodian.

The requirement to execute certain OTC derivatives contracts on SEFs may offer certain advantages over traditional bilateral OTC trading, such as ease of execution, price transparency, increased liquidity and/or favorable pricing. However, SEF trading may make it more difficult and costly for a Fund to enter into highly tailored or customized transactions and may result in additional costs and risks. Market participants such as the Funds that execute derivatives contracts through a SEF, whether directly or through a broker intermediary, are required to submit to the jurisdiction of the SEF and comply with SEF and CFTC rules and regulations which impose, among other things disclosure and recordkeeping obligations. In addition, a Fund will generally incur SEF or broker intermediary fees when it trades on a SEF. A Fund may also be required to indemnify the SEF or broker intermediary for any losses or costs that may result from the Fund’s transactions on the SEF.

Total Return Swaps. A Fund may enter into total return swap transactions for investment purposes. Total return swaps are transactions in which one party agrees to make periodic payments based on the change in market value of the underlying assets, which may include a specified security, basket of securities or security indexes during the specified period, in return for periodic payments based on a fixed or variable interest rate of the total return from other underlying assets. Total return swaps may be used to obtain exposure to a security or market without owning or taking physical custody of such security or market, including in cases in which there may be disadvantages associated with direct ownership of a particular security. In a typical total return equity swap, payments made by a Fund or the counterparty are based on the total return of a particular reference asset or assets (such as an equity security, a combination of such securities, or an index). That is, one party agrees to pay another party the return on a stock, basket of stocks, or stock index in return for a specified interest rate. By entering into an equity index swap, for example, the index receiver can gain exposure to stocks making up the index of securities without actually purchasing those stocks. Total return swaps involve not only the risk associated with the investment in the underlying securities, but also the risk of the counterparty not fulfilling its obligations under the agreement.

Credit Default Swaps. A Fund may enter into credit default swap transactions for investment purposes. A credit default swap transaction may have as reference obligations one or more securities that are not currently held by the Fund. A Fund may be either the protection buyer or protection seller in the transaction. Credit default swaps may also be structured based on the debt of a basket of issuers, rather than a single issuer, and may be customized with respect to the default event that triggers purchase or other factors. As a protection seller, a Fund would generally receive an upfront payment or a fixed rate of income throughout the term of the swap, which typically is between six months and three years, provided that there is no credit event. If a credit event occurs, generally the protection seller must pay the protection buyer the full face amount of the reference obligations that may have little or no value. The notional value of the credit default swap will be used to segregate liquid assets for selling protection on credit default swaps. If a Fund were a protection buyer and no credit event occurred during the term of the swap, the Fund would recover nothing if the swap were held through its termination date. However, if a credit event occurred, the protection buyer may elect to receive the full notional value of the swap in exchange for an equal face amount of the reference obligation that may have little or no value. Where a Fund is the protection buyer, credit default swaps involve the risk that the seller may fail to satisfy its payment obligations to the Fund in the event of a default. The purchase of credit default swaps involves costs, which will reduce a Fund’s return. When a Fund buys credit default swaps it will segregate an amount at least equal to the amount of any accrued premium payment obligations including amounts for early terminations.

Currency Swaps. A Fund may enter into currency swap transactions for investment purposes. Currency swaps are similar to interest rate swaps, except that they involve multiple currencies. A Fund may enter into a currency swap when it has exposure to one currency and desires exposure to a different currency. Typically, the interest rates that determine the currency swap payments are fixed, although occasionally one or both parties may pay a floating rate of interest. Unlike an interest rate swap, however, the principal amounts are exchanged at the beginning of the contract and returned at the end of the contract. In addition to paying and receiving amounts at the beginning and end of the transaction, both sides will have to pay in full on a periodic basis based upon the currency they have borrowed. Change in foreign exchange rates and changes in interest rates, as described above, may negatively affect currency swaps.

Interest Rate Swaps. A Fund may enter into an interest rate swap in an effort to protect against declines in the value of fixed income securities held by the Fund. In such an instance, the Fund may agree to pay a fixed rate (multiplied by a notional amount) while a counterparty agrees to pay a floating rate (multiplied by the same notional amount). If interest rates rise, resulting in a diminution in the value of the Fund’s portfolio, the Fund would receive payments under the swap that would offset, in whole or in part, such diminution in value.

Options on Swaps. An option on a swap agreement, or a “swaption,” is a contract that gives a counterparty the right (but not the obligation) to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. In return, the purchaser pays a “premium” to the seller of the contract. The seller of the contract receives the premium and bears the risk of unfavorable changes on the underlying swap. A Fund may write (sell) and purchase put and call swaptions. A Fund may also enter into swaptions on either an asset-based or liability-based basis, depending on whether the Fund is hedging its assets or its liabilities. A Fund may write (sell) and purchase put and call swaptions to the same extent it may make use of standard options on securities or other instruments. A Fund may enter into these transactions primarily to preserve a return or spread on a particular investment or portion of its holdings, as a duration management technique, to protect against an increase in the price of securities the Fund anticipates purchasing at a later date, or for any other purposes, such as for speculation to increase returns. Swaptions are generally subject to the same risks involved in a Fund’s use of options.

Depending on the terms of the particular option agreement, a Fund will generally incur a greater degree of risk when it writes a swaption than it will incur when it purchases a swaption. When a Fund purchases a swaption, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when a Fund writes a swaption, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement.

Government Regulation. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) that was signed into law on July 21, 2010 created a new statutory framework that comprehensively regulated the over-the-counter (“OTC”) derivatives markets for the first time. Prior to the Dodd-Frank Act, the OTC derivatives markets were traditionally traded on a bilateral basis (so-called “bilateral OTC transactions”). Under the Dodd-Frank Act, certain OTC derivatives transactions are now required to be centrally cleared and traded on exchanges or electronic trading platforms called swap execution facilities (“SEFs”).

On October 28, 2020, the SEC adopted Rule 18f-4 (the “Derivatives Rule”) under the 1940 Act which, following an implementation period, will replace existing SEC and staff guidance with an updated, comprehensive framework for registered funds’ use of derivatives. Among other changes, the Derivatives Rule will require the Funds to trade derivatives and certain other instruments that create future payment or delivery obligations subject to a value-at-risk (“VaR”) leverage limit, develop and implement a derivatives risk management program and new testing requirements, and comply with new requirements related to board and SEC reporting. These new requirements will apply unless a Fund qualifies as a “limited derivatives user,” as defined in the Derivatives Rule. To the extent a Fund uses derivatives, complying with the Derivatives Rule may increase the cost of a Fund’s investments and cost of doing business, which could adversely affect investors. Other new regulations could adversely affect the value, availability and performance of certain derivative instruments, may make them more costly, and may limit or restrict their use by the Funds.

Regulation Under the Commodity Exchange Act. Each Fund intends to use commodity interests, such as futures, swaps and options on futures in accordance with Rule 4.5 of the CEA. A Fund may use exchange-traded futures and options on futures, together with positions in cash and money market instruments, to simulate full investment in its underlying Index. Exchange-traded futures and options on futures contracts may not be currently available for an Index. Under such circumstances, the Adviser may seek to utilize other instruments that it believes to be correlated to the applicable Index components or a subset of the components. An exclusion from the definition of the term “commodity pool operator” has been claimed with respect to each series of the Trust in accordance with Rule 4.5 such that registration or regulation as a commodity pool operator under the CEA is not necessary.

Restrictions on Trading in Commodity Interests. Each Fund reserves the right to engage in transactions involving futures, options thereon and swaps to the extent allowed by the CFTC regulations in effect from time to time and in accordance with a Fund’s policies. Each Fund would take steps to prevent its futures positions from “leveraging” its securities holdings. When it has a long futures position, it will maintain with its custodian bank assets substantially identical to those underlying the contract or cash and equivalents (or a combination of the foregoing) having a value equal to the net obligation of the Fund under the contract (less the value of any margin deposits in connection with the position). When it has a short futures position, it will maintain with its custodian bank assets substantially identical to those underlying the contract or cash and equivalents (or a combination of the foregoing) having a value equal to the net obligation of the Fund under the contract (less the value of any margin deposits in connection with the position).

Derivatives Risk. Under recently adopted rules by the CFTC, transactions in some types of interest rate swaps and index credit default swaps on North American and European indices are required to be cleared. In addition, the CFTC may promulgate additional regulations that require clearing of other classes of swaps. In a cleared derivatives transaction (which includes commodities futures and cleared swaps transactions), a Fund’s counterparty is a clearing house (such as CME, ICE Clear Credit or LCH.Clearnet), rather than a bank or broker. Since each Fund is not a member of a clearing house and only members of a clearing house can participate directly in the clearing house, a Fund holds cleared derivatives through accounts at clearing members, who are futures commission merchants that are members of the clearing houses and who have the appropriate regulatory approvals to engage in cleared swap transactions. A Fund makes and receives payments owed under cleared derivatives transactions (including margin payments) through its accounts at clearing members. Clearing members guarantee performance of their clients’ obligations to the clearing house. In contrast to bilateral OTC transactions, clearing members generally can require termination of existing cleared derivatives transactions at any time and increases in margin above the margin that it required at the beginning of a transaction. Clearing houses also have broad rights to increase margin requirements for existing transactions and to terminate transactions. Any such increase or termination could interfere with the ability of a Fund to pursue its investment strategy. Also, a Fund is subject to execution risk if it enters into a derivatives transaction that is required to be cleared (or that the Advisor expects to be cleared), and no clearing member is willing or able to clear the transaction on the Fund’s behalf. While the documentation in place between a Fund and their clearing members generally provides that the clearing members will accept for clearing all transactions submitted for clearing that are within credit limits specified by the clearing members in advance, the Fund could be subject to this execution risk if the Fund submits for clearing transactions that exceed such credit limits, if the clearing house does not accept the transactions for clearing, or if the clearing members do not comply with their agreement to clear such transactions. In that case, the transaction might have to be terminated, and the Fund could lose some or all of the benefit of any increase in the value of the transaction after the time of the transaction. In addition, new regulations could, among other things, restrict a Fund’s ability to engage in, or increase the cost to the Fund of, derivatives transactions, for example, by making some types of derivatives no longer available to the Fund or increasing margin or capital requirements. If a Fund is not able to enter into a particular derivatives transaction, the Fund’s investment performance and risk profile could be adversely affected as a result.

Counterparty Risk. Counterparty risk with respect to OTC derivatives may be affected by new regulations promulgated by the CFTC and SEC affecting the derivatives market. As described under “Derivatives Risk” above, some derivatives transactions are required to be cleared, and a party to a cleared derivatives transaction is subject to the credit risk of the clearing house and the clearing member through which it holds its cleared derivatives position, rather than the credit risk of its original counterparty to the derivative transaction. Clearing members are required to segregate all funds received from customers with respect to cleared derivatives transactions from the clearing member’s proprietary assets. However, all funds and other property received by a clearing broker from its customers are generally held by the clearing broker on a commingled basis in an omnibus account, which may also invest those funds in certain instruments permitted under the applicable regulations. Also, the clearing member transfers to the clearing house the amount of margin required by the clearing house for cleared derivatives transactions, which amounts are generally held in the relevant omnibus account at the clearing house for all customers of the clearing member.

For commodities futures positions, the clearing house may use all of the collateral held in the clearing member’s omnibus account to meet a loss in that account, without regard to which customer in fact supplied that collateral. Accordingly, in addition to bearing the credit risk of its clearing member, each customer to a futures transaction also bears “fellow customer” risk from other customers of the clearing member. However, with respect to cleared swaps positions, recent regulations promulgated by the CFTC require that the clearing member notify the clearing house of the amount of initial margin provided by the clearing member to the clearing house that is attributable to each customer. Because margin in respect of cleared swaps must be earmarked for specific clearing member customers, the clearing house may not use the collateral of one customer to cover the obligations of another customer. However, if the clearing member does not provide accurate reporting, a Fund is subject to the risk that a clearing house will use the Fund’s assets held in an omnibus account at the clearing house to satisfy payment obligations of a defaulting customer of the clearing member to the clearing house. In addition, clearing members may generally choose to provide to the clearing house the net amount of variation margin required for cleared swaps for all of its customers in the aggregate, rather than the gross amount for each customer.

A Fund may take advantage of opportunities in the area of options and futures contracts, options on futures contracts, warrants, swaps and any other investments which are not presently contemplated for use by the Fund or which are not currently available but which may be developed, to the extent such opportunities are both consistent with the Fund’s investment objective and legally permissible for the Fund. Before entering into such transactions or making any such investment, a Fund will provide appropriate disclosure.

Investment in high yield securities (commonly known as “junk” bonds) generally provides greater income and increased opportunity for capital appreciation than investments in higher quality securities, but they also typically entail greater price volatility and credit risk. These high yield securities are regarded as predominantly speculative with respect to the issuer’s continuing ability to meet principal and interest payments. Analysis of the creditworthiness of issuers of debt securities that are high yield may be more complex than for issuers of higher quality debt securities. In addition, high yield securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) firms, but can also be issued by governments. Such issuers are generally less able than more financially stable issuers to make scheduled payments of interest and principal. The risks posed by securities issued under such circumstances are substantial.

Investing in high yield debt securities involves risks that are greater than the risks of investing in higher quality debt securities. These risks include: (i) changes in credit status, including weaker overall credit conditions of issuers and risks of default; (ii) industry, market and economic risk; and (iii) greater price variability and credit risks of certain high yield securities such as zero coupon and payment-in-kind securities. While these risks provide the opportunity for maximizing return over time, they may result in greater volatility of the value of the Fund than a fund that invests in higher-rated securities.

Furthermore, the value of high yield securities may be more susceptible to real or perceived adverse economic, company or industry conditions than is the case for higher quality securities. The market values of certain of these lower-rated and unrated debt securities tend to reflect individual issuer developments to a greater extent than do higher-rated securities which react primarily to fluctuations in the general level of interest rates, and tend to be more sensitive to economic conditions than are higher-rated securities. Adverse market, credit or economic conditions could make it difficult at certain times to sell certain high yield securities held by the Fund.

The secondary market on which high yield securities are traded may be less liquid than the market for higher grade securities. Less liquidity in the secondary trading market could adversely affect the price at which a Fund could sell a high yield security, and could adversely affect the daily net asset value per share of a Fund. When secondary markets for high yield securities are less liquid than the market for higher grade securities, it may be more difficult to value the securities because there is less reliable, objective data available.

The use of credit ratings as a principal method of selecting high yield securities can involve certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield securities. Also, credit rating agencies may fail to change credit ratings in a timely fashion to reflect events since the security was last rated.

Each Fund may invest in illiquid securities. A Fund may not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of its net assets in illiquid securities. An illiquid security means any security that a Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. If illiquid securities exceed 15% of a Fund’s net assets, certain remedial actions will be taken as required by Rule 22e-4 under the 1940 Act and the Funds’ policies and procedures.

Each Fund may invest in inflation-protected public obligations, commonly known as “TIPS,” of the U.S. Treasury, as well as TIPS of major governments and emerging market countries, excluding the United States. TIPS are a type of security issued by a government that are designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation—a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, such as the Consumer Price Index. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises or falls, both the principal value and the interest payments will increase or decrease. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

Each Fund may invest in the securities of other investment companies, including affiliated funds and money market funds, subject to applicable limitations under Section 12(d)(1) of the 1940 Act. Pursuant to Section 12(d)(1), a Fund may invest in the securities of another investment company (the “acquired company”) provided that the Fund, immediately after such purchase or acquisition, does not own in the aggregate: (i) more than 3% of the total outstanding voting stock of the acquired company; (ii) securities issued by the acquired company having an aggregate value in excess of 5% of the value of the total assets of the Fund; or (iii) securities issued by the acquired company and all other investment companies (other than Treasury stock of the Fund) having an aggregate value in excess of 10% of the value of the total assets of the Fund. To the extent allowed by law, regulation, a Fund’s investment restrictions and the Trust’s exemptive relief, a Fund may invest its assets in securities of investment companies that are affiliated funds and/or money market funds in excess of the limits discussed above.

If a Fund invests in and, thus, is a shareholder of, another investment company, the Fund’s shareholders will indirectly bear the Fund’s proportionate share of the fees and expenses paid by such other investment company, including advisory fees, in addition to both the management fees payable directly by the Fund to the Fund’s own investment adviser and the other expenses that the Fund bears directly in connection with the Fund’s own operations.

Each Fund may lend portfolio securities to certain creditworthy borrowers in U.S. and non-U.S. markets in an amount not to exceed 40% of the value of its net assets. The borrowers provide collateral that is marked to market daily in an amount at least equal to the current market value of the securities loaned. A Fund may terminate a loan at any time and obtain the securities loaned. A Fund receives the value of any interest or cash or non-cash distributions paid on the loaned securities. A Fund cannot vote proxies for securities on loan, but may recall loans to vote proxies if a material issue affecting the Fund’s economic interest in the investment is to be voted upon. Efforts to recall such securities promptly may be unsuccessful, especially for foreign securities or thinly traded securities, and may involve expenses to a Fund. Distributions received on loaned securities in lieu of dividend payments (i.e., substitute payments) would not be considered qualified dividend income.

With respect to loans that are collateralized by cash, the borrower will be entitled to receive a fee based on the amount of cash collateral. A Fund is compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, a Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain high quality short-term instruments either directly on behalf of the lending Fund or through one or more joint accounts or funds, which may include those managed by the Adviser. A Fund could lose money due to a decline in the value of collateral provided for loaned securities or any investments made with cash collateral. Certain non-cash collateral or investments made with cash collateral may have a greater risk of loss than other non-cash collateral or investments.

A Fund may pay a portion of the interest or fees earned from securities lending to a borrower as described above, and to one or more securities lending agents approved by the Board of Trustees of the Trust (the “Board”) who administer the lending program for the Funds in accordance with guidelines approved by the Board. In such capacity, the lending agent provides the following services to the Funds in connection with the Funds’ securities lending activities: (i) locating borrowers among an approved list of prospective borrowers; (ii) causing the delivery of loaned securities from a Fund to borrowers; (iii) monitoring the value of loaned securities, the value of collateral received, and other lending parameters; (iv) seeking additional collateral, as necessary, from borrowers; (v) receiving and holding collateral from borrowers, and facilitating the investment and reinvestment of all or substantially all cash collateral in an investment vehicle designated by the Funds; (vi) returning collateral to borrowers; (vii) facilitating substitute dividend, interest, and other distribution payments to the Funds from borrowers; (viii) negotiating the terms of each loan of securities, including but not limited to the amount of any loan premium, and monitoring the terms of securities loan agreements with prospective borrowers for consistency with the requirements of the Funds’ Securities Lending Authorization Agreement; (ix) selecting securities, including amounts (percentages), to be loaned; (x) recordkeeping and accounting servicing; and (xi) arranging for return of loaned securities to the Fund in accordance with the terms of the Securities Lending Authorization Agreement. State Street Bank and Trust Company (“State Street”), an affiliate of the Trust, has been approved by the Board to serve as securities lending agent for a Fund and the Trust has entered into an agreement with State Street for such services. Among other matters, the Trust has agreed to indemnify State Street for certain liabilities. State Street has received an order of exemption from the SEC under Sections 17(a) and 12(d)(1) under the 1940 Act to serve as the lending agent for affiliated investment companies such as the Trust and to invest the cash collateral received from loan transactions to be invested in an affiliated cash collateral fund.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process especially so in certain international markets such as Taiwan), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees a Fund has agreed to pay a borrower), risk of loss of collateral, credit, legal, counterparty and market risk. If a securities lending counterparty were to default, a Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return a Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. Although State Street has agreed to provide a Fund with indemnification in the event of a borrower default, a Fund is still exposed to the risk of losses in the event a borrower does not return a Fund’s securities as agreed. For example, delays in recovery of lent securities may cause a Fund to lose the opportunity to sell the securities at a desirable price.

While the Funds do not anticipate doing so, a Fund may borrow money in an amount greater than 5% of the value of the Fund’s total assets. However, under normal circumstances, a Fund will not borrow money from a bank in an amount greater than 10% of the value of the Fund’s total assets. Borrowing for investment purposes is one form of leverage. Leveraging investments, by purchasing securities with borrowed money, is a speculative technique that increases investment risk, but also increases investment opportunity. Because substantially all of a Fund’s assets will fluctuate in value, whereas the interest obligations on borrowings may be fixed, the NAV of a Fund will increase more when such Fund’s portfolio assets increase in value and decrease more when the Fund’s portfolio assets decrease in value than would otherwise be the case. Moreover, interest costs on borrowings may fluctuate with changing market rates of interest and may partially offset or exceed the returns on the borrowed funds.

The term “U.S. agency mortgage pass-through security” refers to a category of pass-through securities backed by pools of mortgages and issued by one of several U.S. government-sponsored enterprises: the Ginnie Mae, Fannie Mae or FHLMC. In the basic mortgage pass-through structure, mortgages with similar issuer, term and coupon characteristics are collected and aggregated into a “pool” consisting of multiple mortgage loans. The pool is assigned a CUSIP number and undivided interests in the pool are traded and sold as pass-through securities. The holder of the security is entitled to a pro rata share of principal and interest payments (including unscheduled prepayments) from the pool of mortgage loans.

An investment in a specific pool of pass-through securities requires an analysis of the specific prepayment risk of mortgages within the covered pool (since mortgagors typically have the option to prepay their loans). The level of prepayments on a pool of mortgage securities is difficult to predict and can impact the subsequent cash flows and value of the mortgage pool. In addition, when trading specific mortgage pools, precise execution, delivery and settlement arrangements must be negotiated for each transaction. These factors combine to make trading in mortgage pools somewhat cumbersome.

For the foregoing and other reasons, the SPDR Portfolio Aggregate Bond ETF and SPDR Portfolio Mortgage Backed Bond ETF seek to obtain exposure to U.S. agency mortgage pass-through securities primarily through the use of “to-be-announced” or “TBA transactions.” “TBA” refers to a commonly used mechanism for the forward settlement of U.S. agency mortgage pass-through securities, and not to a separate type of mortgage-backed security. Most transactions in mortgage pass-through securities occur through the use of TBA transactions. TBA transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA transaction, the buyer and seller decide on general trade parameters, such as agency, settlement date, par amount, and price. The actual pools delivered generally are determined two days prior to settlement date. Each Fund intends to use TBA transactions in several ways. For example, each Fund expects that it will regularly enter into TBA agreements and “roll over” such agreements prior to the settlement date stipulated in such agreements. This type of TBA transaction is sometimes known as a “TBA roll.” In a “TBA roll” a Fund generally will sell the obligation to purchase the pools stipulated in the TBA agreement prior to the stipulated settlement date and will enter into a new TBA agreement for future delivery of pools of mortgage pass-through securities. In addition, a Fund may enter into TBA agreements and settle such transactions on the stipulated settlement date by accepting actual receipt or delivery of the pools of mortgage pass-through securities stipulated in the TBA agreement.

Default by or bankruptcy of a counterparty to a TBA transaction would expose a Fund to possible loss because of adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA transaction. To minimize this risk, a Fund will enter into TBA transactions only with established counterparties (such as major broker-dealers) and the Adviser will monitor the creditworthiness of such counterparties. In addition, a Fund may accept assignments of TBA transactions from Authorized Participants (as defined below) from time to time. A Fund’s use of “TBA rolls” may cause the Fund to experience higher portfolio turnover, higher transaction costs and to pay higher capital gain distributions to shareholders (which may be taxable) than the other Funds described herein.

The SPDR Portfolio Aggregate Bond ETF and SPDR Portfolio Mortgage Backed Bond ETF intend to invest cash pending settlement of any TBA transactions in money market instruments, repurchase agreements, commercial paper (including asset-backed commercial paper) or other high-quality, liquid short-term instruments, which may include money market funds affiliated with the Adviser.

Municipal securities are securities issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies or authorities. Municipal securities share the attributes of debt/fixed income securities in general, but are generally issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies or authorities. The municipal securities which the Funds may purchase include general obligation bonds and limited obligation bonds (or revenue bonds), including industrial development bonds issued pursuant to former federal tax law. General obligation bonds are obligations involving the credit of an issuer possessing taxing power and are payable from such issuer’s general revenues and not from any particular source. Limited obligation bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other specific revenue source. Tax-exempt industrial development bonds generally are also revenue bonds and thus are not payable from the issuer’s general revenues. The credit and quality of industrial development bonds are usually related to the credit of the corporate user of the facilities. Payment of interest on and repayment of principal of such bonds is the responsibility of the corporate user (and/or any guarantor).

Some longer-term municipal securities give the investor the right to “put” or sell the security at par (face value) within a specified number of days following the investor’s request—usually one to seven days. This demand feature enhances a security’s liquidity by shortening its effective maturity and enables it to trade at a price equal to or very close to par. If a demand feature terminates prior to being exercised, a Fund would hold the longer-term security, which could experience substantially more volatility. The market for municipal bonds may be less liquid than for taxable bonds. This means that it may be harder to buy and sell municipal securities, especially on short notice, than non-municipal securities. There may also be less information available on the financial condition of issuers of municipal securities than for public corporations. This means that it may be harder to buy and sell municipal securities, especially on short notice, and municipal securities may be more difficult for the Funds to value accurately than securities of public corporations. A Fund that invests a significant portion of its portfolio in municipal securities, such as the SPDR Nuveen Bloomberg Barclays Municipal Bond ETF, SPDR Nuveen Bloomberg Barclays Short Term Municipal Bond ETF and SPDR Nuveen Bloomberg Barclays High Yield Municipal Bond ETF (the “Municipal Bond ETFs”), may have greater exposure to liquidity risk than a fund that invests in non-municipal securities. In addition, the municipal securities market is generally characterized as a buy and hold investment strategy. As a result, the accessibility of municipal securities in the market is generally greater closer to the original date of issue of the securities and lessens as the securities move further away from such issuance date.

Municipal securities are subject to credit and market risk. Generally, prices of higher quality issues tend to fluctuate more with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues.

Prices and yields on municipal securities are dependent on a variety of factors, including general money-market conditions, the financial condition of the issuer, general conditions of the municipal security market, the size of a particular offering, the maturity of the obligation and the rating of the issue. A number of these factors, including the ratings of particular issues, are subject to change from time to time. Information about the financial condition of an issuer of municipal securities may not be as extensive as that which is made available by corporations whose securities are publicly traded. As a result, municipal securities may be more difficult to value than securities of public corporations.

Obligations of issuers of municipal securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors. Congress or state legislatures may seek to extend the time for payment of principal or interest, or both, or to impose other constraints upon enforcement of such obligations. In addition, municipal securities are subject to the risk that their tax treatment could be changed by Congress or state legislatures, thereby affecting the value of outstanding municipal securities. There is also the possibility that as a result of litigation or other conditions, the power or ability of issuers to meet their obligations for the payment of interest and principal on their municipal securities may be materially affected or their obligations may be found to be invalid or unenforceable. Such litigation or conditions may from time to time have the effect of introducing uncertainties in the market for municipal securities or certain segments thereof, or of materially affecting the credit risk with respect to particular bonds. Adverse economic, business, legal or political developments might affect all or a substantial portion of a Fund’s municipal securities in the same manner.

Municipal Leases and Certificates of Participation. Also included within the general category of municipal securities described in the Municipal Bond ETFs’ Prospectus are municipal leases, certificates of participation in such lease obligations or installment purchase contract obligations (hereinafter collectively called “Municipal Lease Obligations”) of municipal authorities or entities. Although a Municipal Lease Obligation does not constitute a general obligation of the municipality for which the municipality’s taxing power is pledged, a Municipal Lease Obligation is ordinarily backed by the municipality’s covenant to budget for, appropriate and make the payments due under the Municipal Lease Obligation. However, certain Municipal Lease Obligations contain “non-appropriation” clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. In the case of a “non-appropriation” lease, a Fund’s ability to recover under the lease in the event of non-appropriation or default will be limited solely to the repossession of the leased property, without recourse to the general credit of the lessee, and disposition or releasing of the property might prove difficult.

Municipal Insurance. A municipal security may be covered by insurance that guarantees the bond’s scheduled payment of interest and repayment of principal. This type of insurance may be obtained by either (i) the issuer at the time the bond is issued (primary market insurance), or (ii) another party after the bond has been issued (secondary market insurance).

Both primary and secondary market insurance guarantee timely and scheduled repayment of all principal and payment of all interest on a municipal security in the event of default by the issuer, and cover a municipal security to its maturity, enhancing its credit quality and value.

Municipal security insurance does not insure against market fluctuations or fluctuations in a Fund’s share price. In addition, a municipal security insurance policy will not cover: (i) repayment of a municipal security before maturity (redemption), (ii) prepayment or payment of an acceleration premium (except for a mandatory sinking fund redemption) or any other provision of a bond indenture that advances the maturity of the bond, or (iii) nonpayment of principal or interest caused by negligence or bankruptcy of the paying agent. A mandatory sinking fund redemption may be a provision of a municipal security issue whereby part of the municipal security issue may be retired before maturity.

Because a significant portion of the municipal securities issued and outstanding is insured by a small number of insurance companies, an event involving one or more of these insurance companies could have a significant adverse effect on the value of the securities insured by that insurance company and on the municipal markets as a whole.

Municipal Market Disruption Risk. The value of municipal securities may be affected by uncertainties in the municipal market related to legislation or litigation involving the taxation of municipal securities or the rights of municipal securities holders in the event of a bankruptcy. Proposals to restrict or eliminate the federal income tax exemption for interest on municipal securities are introduced before Congress from time to time. Proposals also may be introduced before state legislatures that would affect the state tax treatment of a municipal fund’s distributions. If such proposals were enacted, the availability of municipal securities and the value of a municipal fund’s holdings would be affected, and the Trustees would reevaluate a Municipal Bond ETF’s investment objectives and policies. Municipal bankruptcies are relatively rare, and certain provisions of the U.S. Bankruptcy Code governing such bankruptcies are unclear and remain untested. Further, the application of state law to municipal issuers could produce varying results among the states or among municipal securities issuers within a state. These legal uncertainties could affect the municipal securities market generally, certain specific segments of the market, or the relative credit quality of particular securities. Any of these effects could have a significant impact on the prices of some or all of the municipal securities held by a Fund.

Each Fund may invest in short-term instruments, including money market instruments, (including money market funds advised by the Adviser), cash and cash equivalents, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include but are not limited to: (i) shares of money market funds (including those advised by the Adviser); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed time deposits and other obligations of U.S. and foreign banks (including foreign branches) and similar institutions; (iv) commercial paper rated at the date of purchase “Prime-1” by Moody’s Investors Service (“Moody’s”) or “A-1” by Standard & Poor’s (“S&P”), or if unrated, of comparable quality as determined by the Adviser; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that present minimal credit risk; and (vi) short-term U.S. dollar-denominated obligations of foreign banks (including U.S. branches) that, in the opinion of the Adviser, are of comparable quality to obligations of U.S. banks which may be purchased by a Fund. Any of these instruments may be purchased on a current or a forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions. Money market instruments also include shares of money market funds. The SEC and other government agencies continue to review the regulation of money market funds. The SEC has adopted changes to the rules that govern money market funds, and compliance with many of these amendments was required in October 2016. Legislative developments may also affect money market funds. These changes and developments may affect the investment strategies, performance, yield, operating expenses and continued viability of a money market fund.

Preferred securities pay fixed or adjustable rate interest or dividends to investors, and are generally senior to common stock, but subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. There is no assurance that interest payments, dividends or distributions on the preferred securities in which a Fund invests will be declared or otherwise made payable. In the case of preferred stock, in order to be payable, distributions on preferred securities must be declared by the issuer’s board of directors. The market value of preferred securities may be affected by favorable and unfavorable changes impacting companies in the utilities and financial services sectors, which are prominent issuers of preferred securities, and by actual and anticipated changes in tax laws.

Because the claim on an issuer’s earnings represented by preferred securities may become onerous when interest rates fall below the rate payable on such securities, the issuer may redeem the securities. Thus, in declining interest rate environments in particular, a Fund’s holdings of higher rate-paying fixed rate preferred securities may be reduced and the Fund would be unable to acquire securities paying comparable rates with the redemption proceeds.

Each Fund may invest in securities that are purchased in private placements and, accordingly, are subject to restrictions on resale as a matter of contract or under federal securities laws. While such private placements may offer attractive opportunities for investment not otherwise available on the open market, the securities so purchased are often “restricted securities,” i.e., securities which cannot be sold to the public without registration under the Securities Act or the availability of an exemption from registration (such as Rules 144 or 144A), or which are not readily marketable because they are subject to other legal or contractual delays in or restrictions on resale. Generally speaking, restricted securities may be sold only to qualified institutional buyers, or in a privately negotiated transaction to a limited number of purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met pursuant to an exemption from registration, or in a public offering for which a registration statement is in effect under the Securities Act.

Because there may be relatively few potential purchasers for such investments, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, a Fund could find it more difficult to sell such securities when the Adviser believes it advisable to do so or may be able to sell such securities only at prices lower than if such securities were more widely held. Market quotations for such securities are generally less readily available than for publicly traded securities. The absence of a trading market can make it difficult to ascertain a market value for such securities for purposes of computing a Fund’s net asset value, and the judgment of the Adviser may at times play a greater role in valuing these securities than in the case of publicly traded securities. Disposing of such securities, which may be illiquid investments, can involve time-consuming negotiation and legal expenses, and it may be difficult or impossible for a Fund to sell them promptly at an acceptable price. A Fund may have to bear the extra expense of registering such securities for resale and the risk of substantial delay in effecting such registration.

A Fund may be deemed to be an “underwriter” for purposes of the Securities Act when selling restricted securities to the public, and in such event the Fund may be liable to purchasers of such securities if the registration statement prepared by the issuer, or the prospectus forming a part of it, is materially inaccurate or misleading.

An investment grade rating means the security or issuer is rated investment grade by Moody’s, S&P, Fitch, Inc. (“Fitch”), Dominion Bond Rating Service Limited, or another credit rating agency designated as a nationally recognized statistical rating organization by the SEC, or is unrated but considered to be of equivalent quality by the Adviser or applicable Sub-Adviser.

Subsequent to purchase by a Fund, a rated security may cease to be rated or its investment grade rating may be reduced below an investment grade rating. Bonds rated lower than Baa3 by Moody’s or BBB- by S&P or Fitch are below investment grade quality and are obligations of issuers that are considered predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Such securities (“lower rated securities”) are commonly referred to as “junk bonds” and are subject to a substantial degree of credit risk. Lower rated securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) firms, which are generally less able than more financially stable firms to make scheduled payments of interest and principal. The risks posed by securities issued under such circumstances are substantial. Bonds rated below investment grade tend to be less marketable than higher-quality bonds because the market for them is less broad. The market for unrated bonds is even narrower. See “HIGH YIELD SECURITIES” above for more information relating to the risks associated with investing in lower rated securities, or Appendix D for more information on the ratings of debt instruments.

REITs pool investors’ funds for investment primarily in income producing real estate or real estate loans or interests. A REIT is not taxed on income distributed to shareholders if it complies with several requirements relating to its organization, ownership, assets, and income and a requirement that it distribute to its shareholders at least 90% of its taxable income (other than net capital gains) for each taxable year. REITs can generally be classified as Equity REITs, Mortgage REITs and Hybrid REITs. Equity REITs, which invest the majority of their assets directly in real property, derive their income primarily from rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs, which invest the majority of their assets in real estate mortgages, derive their income primarily from interest payments. Hybrid REITs combine the characteristics of both Equity REITs and Mortgage REITs. The Funds will not invest in real estate directly, but only in securities issued by real estate companies. However, the Funds may be subject to risks similar to those associated with the direct ownership of real estate (in addition to securities markets risks) to the extent they invest in the securities of companies in the real estate industry. These include declines in the value of real estate, risks related to general and local economic conditions, dependency on management skill, heavy cash flow dependency, possible lack of availability of mortgage funds, overbuilding, extended vacancies of properties, increased competition, increases in property taxes and operating expenses, changes in zoning laws, losses due to costs resulting from the clean-up of environmental problems, liability to third parties for damages resulting from environmental problems, casualty or condemnation losses, limitations on rents, changes in neighborhood values, the appeal of properties to tenants and changes in interest rates. Investments in REITs may subject Fund shareholders to duplicate management and administrative fees.

In addition to these risks, Equity REITs may be affected by changes in the value of the underlying property owned by the trusts, while Mortgage REITs may be affected by the quality of any credit extended. Further, Equity and Mortgage REITs are dependent upon management skills and generally may not be diversified. Equity and Mortgage REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, Equity and Mortgage REITs could possibly fail to qualify for the beneficial tax treatment available to REITs under the Internal Revenue Code, or to maintain their exemptions from registration under the 1940 Act. The above factors may also adversely affect a borrower’s or a lessee’s ability to meet its obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

Each Fund may invest in repurchase agreements with commercial banks, brokers or dealers to generate income from its excess cash balances and to invest securities lending cash collateral. A repurchase agreement is an agreement under which a Fund acquires a financial instrument (e.g., a security issued by the U.S. government or an agency thereof, a banker’s acceptance or a certificate of deposit) from a seller, subject to resale to the seller at an agreed upon price and date (normally, the next Business Day—as defined below). A repurchase agreement may be considered a loan collateralized by securities. The resale price reflects an agreed upon interest rate effective for the period the instrument is held by a Fund and is unrelated to the interest rate on the underlying instrument.

In these repurchase agreement transactions, the securities acquired by a Fund (including accrued interest earned thereon) must have a total value in excess of the value of the repurchase agreement and are held by the Custodian until repurchased. No more than an aggregate of 15% of a Fund’s net assets will be invested in illiquid securities, including repurchase agreements having maturities longer than seven days and securities subject to legal or contractual restrictions on resale, or for which there are no readily available market quotations.

The use of repurchase agreements involves certain risks. For example, if the other party to the agreement defaults on its obligation to repurchase the underlying security at a time when the value of the security has declined, a Fund may incur a loss upon disposition of the security. If the other party to the agreement becomes insolvent and subject to liquidation or reorganization under the U.S. Bankruptcy Code or other laws, a court may determine that the underlying security is collateral for a loan by a Fund not within the control of the Fund and, therefore, the Fund may not be able to substantiate its interest in the underlying security and may be deemed an unsecured creditor of the other party to the agreement.

Each Fund may enter into reverse repurchase agreements, which involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. The securities purchased with the funds obtained from the agreement and securities collateralizing the agreement will have maturity dates no later than the repayment date. Generally the effect of such transactions is that a Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases a Fund is able to keep some of the interest income associated with those securities. Such transactions are only advantageous if a Fund has an opportunity to earn a greater rate of interest on the cash derived from these transactions than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available and a Fund intends to use the reverse repurchase technique only when the Adviser believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any interim increase or decrease in the value of a Fund’s assets. A Fund’s exposure to reverse repurchase agreements will be covered by securities having a value equal to or greater than such commitments. Under the 1940 Act, reverse repurchase agreements are considered borrowings. Although there is no percentage limit on Fund assets that can be used in connection with reverse repurchase agreements, the Funds do not expect to engage, under normal circumstances, in reverse repurchase agreements with respect to more than 10% of their respective total assets.

Sovereign debt obligations are issued or guaranteed by foreign governments or their agencies. Sovereign debt may be in the form of conventional securities or other types of debt instruments such as loans or loan participations. Governmental entities responsible for repayment of the debt may be unable or unwilling to repay principal and pay interest when due, and may require renegotiation or reschedule of debt payments. In addition, prospects for repayment of principal and payment of interest may depend on political as well as economic factors. Although some sovereign debt, such as Brady Bonds, is collateralized by U.S. Government securities, repayment of principal and payment of interest is not guaranteed by the U.S. Government.

U.S. Government obligations are a type of bond. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities.

One type of U.S. Government obligation, U.S. Treasury obligations, are backed by the full faith and credit of the U.S. Treasury and differ only in their interest rates, maturities, and times of issuance. U.S. Treasury bills have initial maturities of one-year or less; U.S. Treasury notes have initial maturities of one to ten years; and U.S. Treasury bonds generally have initial maturities of greater than ten years.

Other U.S. Government obligations are issued or guaranteed by agencies or instrumentalities of the U.S. Government including, but not limited to, Federal National Mortgage Association (“Fannie Mae”), the Government National Mortgage Association (“Ginnie Mae”), the Small Business Administration, the Federal Farm Credit Administration, the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal Home Loan Banks (“FHLB”), Banks for Cooperatives (including the Central Bank for Cooperatives), the Federal Land Banks, the Federal Intermediate Credit Banks, the Tennessee Valley Authority, the Export-Import Bank of the United States, the Commodity Credit Corporation, the Federal Financing Bank, the Student Loan Marketing Association, the National Credit Union Administration and the Federal Agricultural Mortgage Corporation (Farmer Mac). Some obligations issued or guaranteed by U.S. Government agencies and instrumentalities, including, for example, Ginnie Mae pass-through certificates, are supported by the full faith and credit of the U.S. Treasury. Other obligations issued by or guaranteed by federal agencies, such as those securities issued by Fannie Mae, are supported by the discretionary authority of the U.S. Government to purchase certain obligations of the federal agency, while other obligations issued by or guaranteed by federal agencies, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the U.S. Treasury. While the U.S. Government provides financial support to such U.S. Government-sponsored federal agencies, no assurance can be given that the U.S. Government will always do so, since the U.S. Government is not so obligated by law.

In September 2008, the U.S. Treasury announced a federal takeover of Fannie Mae and Freddie Mac, placing the two federal instrumentalities in conservatorship. Under the terms of the takeover, the U.S. Treasury agreed to acquire $1 billion of senior preferred stock of each instrumentality and obtained warrants for the purchase of common stock of each instrumentality. Under these Senior Preferred Stock Purchase Agreements (“SPAs”), the U.S. Treasury has pledged to provide a limited amount of capital per instrumentality as needed, including the contribution of cash capital to the instrumentalities in the event their liabilities exceed their assets. In May 2009, the U.S. Treasury increased its maximum commitment to each instrumentality under the SPAs from $100 billion to $200 billion per instrumentality. In December 2009, the U.S. Treasury amended the SPAs to provide Fannie Mae and Freddie Mac with some additional flexibility to meet the requirement to reduce their mortgage portfolios. Also in December 2009, the U.S. Treasury further amended the SPAs to allow the cap on the U.S. Treasury’s funding commitment to increase as necessary to accommodate any cumulative reduction in Fannie Mae’s and Freddie Mac’s net worth through the end of 2012. On August 17, 2012, the U.S. Treasury announced that it was again amending the SPAs to terminate the requirement that Fannie Mae and Freddie Mac each pay a 10% dividend annually on all amounts received under the funding commitment. Instead, they were required to transfer to the U.S. Treasury on a quarterly basis all profits earned during a quarter that exceeded a capital reserve amount of $3 billion. On September 30, 2019, the U.S. Treasury announced amendments to the SPAs permitting Fannie Mae and Freddie Mac to maintain capital reserves of $25 billion and $20 billion, respectively. It is believed that the amendment puts Fannie Mae and Freddie Mac in a better position to service their debt because the companies no longer have to borrow from the U.S. Treasury to make fixed dividend payments.

Fannie Mae and Freddie Mac are the subject of several continuing class action lawsuits and investigations by federal regulators over certain accounting, disclosure or corporate governance matters, which (along with any resulting financial restatements) may adversely affect the guaranteeing entities. Importantly, the future of the entities is in serious question as the U.S. government reportedly is considering multiple options, ranging from nationalization, privatization, consolidation, or abolishment of the entities.

Investing in U.S. registered, dollar-denominated, securities issued by non-U.S. issuers involves some risks and considerations not typically associated with investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries, and potential restrictions of the flow of international capital. Foreign companies may be subject to less governmental regulation than U.S. issuers. Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

A Fund’s investment in common stock of foreign corporations may also be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively “Depositary Receipts”). Depositary Receipts are receipts, typically issued by a bank or trust company, which evidence ownership of underlying securities issued by a foreign corporation. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a foreign issuer. For other Depositary Receipts, the depository may be a foreign or a U.S. entity, and the underlying securities may have a foreign or a U.S. issuer. Depositary Receipts will not necessarily be denominated in the same currency as their underlying securities. Generally, ADRs, in registered form, are designed for use in the U.S. securities markets, and EDRs, in bearer form, are designated for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world. A Fund may invest in unsponsored Depositary Receipts. The issuers of unsponsored Depositary Receipts are not obligated to disclose material information in the United States, and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the Depositary Receipts.

Variable rate securities are instruments issued or guaranteed by entities such as (1) US Government, or an agency or instrumentality thereof, (2) states, municipalities and other political subdivisions, agencies, authorities and instrumentalities or states and multi-state agencies or authorities (3) corporations, (4) financial institutions, (5) insurance companies or (6) trusts that have a rate of interest subject to adjustment at regular intervals but less frequently than annually. A variable rate security provides for the automatic establishment of a new interest rate on set dates. Variable rate obligations whose interest is readjusted no less frequently than annually will be deemed to have a maturity equal to the period remaining until the next readjustment of the interest rate. The Funds may also purchase floating rate securities. A floating rate security provides for the automatic adjustment of its interest rate whenever a specified interest rate changes. Interest rates on these securities are ordinarily tied to, and are a percentage of, a widely recognized interest rate, such as the yield on 90-day US Treasury bills or the prime rate of a specified bank. These rates may change as often as twice daily. Generally, changes in interest rates will have a smaller effect on the market value of variable and fixed rate floating rate securities than on the market value of comparable fixed rate fixed income obligations. Thus, investing in variable and fixed rate floating rate securities generally allows less opportunity for capital appreciation and depreciation than investing in comparable fixed rate fixed income securities.

Variable rate demand obligations (“VRDOs”) are short-term tax-exempt fixed income instruments whose yield is reset on a periodic basis. VRDO securities tend to be issued with long maturities of up to 30 or 40 years; however, they are considered short-term instruments because they include a put feature which coincides with the periodic yield reset. For example, a VRDO whose yield resets weekly will have a put feature that is exercisable upon seven days’ notice. VRDOs are put back to a bank or other entity that serves as a liquidity provider, who then tries to resell the VRDOs or, if unable to resell, holds them in its own inventory. VRDOs are generally supported by either a Letter of Credit or a Stand-by Bond Purchase Agreement to provide credit enhancement.

A Fund may purchase securities on a when-issued basis. Delivery of and payment for these securities may take place as long as a month or more after the date of the purchase commitment. The value of these securities is subject to market fluctuation during this period, and no income accrues to the Fund until settlement takes place. When entering into a when-issued transaction, a Fund will rely on the other party to consummate the transaction; if the other party fails to do so, the Fund may be disadvantaged.

Securities purchased on a when-issued basis and held by a Fund are subject to changes in market value based upon actual or perceived changes in the level of interest rates. Generally, the value of such securities will fluctuate inversely to changes in interest rates — i.e., they will appreciate in value when interest rates decline and decrease in value when interest rates rise. Therefore, if a Fund purchases securities on a when-issued basis, there may be a greater possibility of fluctuation in the Fund’s NAV.

A discussion of the risks associated with an investment in each Fund is contained in the Prospectus. The discussion below supplements, and should be read in conjunction with, the Prospectus.

Investment in a Fund should be made with an understanding that the value of a Fund’s portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of securities generally and other factors.

An investment in a Fund should also be made with an understanding of the risks inherent in an investment in securities, including the risk that the financial condition of issuers may become impaired or that the general condition of the securities markets may deteriorate (either of which may cause a decrease in the value of the portfolio securities and thus in the value of Shares). Securities are susceptible to general market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic and banking crises. Securities of issuers traded on exchanges may be suspended on certain exchanges by the issuers themselves, by an exchange or by government authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and instruments that reference the securities, such as participatory notes (or “P-notes”) or other derivative instruments, may be halted.

The principal trading market for some of the securities in an Index may be in the over-the-counter market. The existence of a liquid trading market for certain securities may depend on whether dealers will make a market in such securities. There can be no assurance that a market will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of a Fund’s Shares will be adversely affected if trading markets for a Fund’s portfolio securities are limited or absent or if bid/ask spreads are wide.

The SPDR Bloomberg Barclays Emerging Markets USD Bond ETF may invest in renminbi (“RMB”) denominated fixed income securities of Chinese issuers (“China bonds”). To the extent the Fund’s underlying Index includes China bonds, the Fund’s ability to achieve its investment objective is dependent on its continued access to such bonds. The Fund may invest in China bonds (i) through direct access to the China Interbank Bond Market (“CIBM”), (ii) through certain foreign institutional investors that have obtained a license from the Chinese regulators, and (iii) through Bond Connect, a program that provides foreign investors with access to China’s onshore bond market.

CIBM Direct Access Program Risks. The CIBM is an OTC market established in 1997, and accounts for more than 95% of outstanding bond values of the total trading volume in the People’s Republic of China (the “PRC”). On CIBM, domestic institutional investors and certain foreign institutional investors can trade, on a one-to-one quote-driven basis, sovereign bonds, government bonds, corporate bonds, bond repo, bond lending, bills issued by the People’s Bank of China (“PBOC”) and other financial debt instruments. Pursuant to the Announcement (2016) No. 3 issued by the PBOC on February 24, 2016, eligible foreign institutional investors can conduct trading on the CIBM under a program established by the PBOC (“CIBM Direct Access Program”) subject to other rules and regulations as promulgated by the PRC authorities. There is no trading quota limitation.

CIBM is regulated and supervised by the PBOC. The PBOC is responsible for, among others, promulgating the applicable CIBM listing, trading and operating rules, and supervising the market operators of CIBM. Bonds and bond-related derivatives are traded in the CIBM primarily through (i) independent bilateral negotiation on a transaction by transaction basis or (ii) through the “click-and-deal” trading model, whereby a party offers a quote in the market that can then be accepted by a counterparty (thus, “clicking” the “deal”). A “click-and-deal” quote may also be automatically matched with a price limit order. In addition, recently an “anonymous click” trading model has been implemented for certain bonds and bond-related derivatives whereby anonymous quotes offered in the market are automatically matched with counterparties based on timing and price. Once a transaction is agreed upon, the parties will, in accordance with the terms of the transaction, promptly send instructions for the delivery of bonds and funds. Parties are required to have sufficient bonds and funds for delivery on the agreed upon delivery date. China Central Depository & Clearing Co., Ltd (“CCDC”) or Shanghai Clearing House (“SHCH”) will deliver bonds according to the instructions sent by the parties. Fund clearing banks will handle the transfer and settlement of the payments of the bonds on behalf of the parties. The China Foreign Exchange Trading System is the unified trading platform for CIBM.

The Fund’s investments in China bonds through the CIBM Direct Access Program will be subject to a number of additional risks and restrictions that may affect the Fund’s investments and returns. Certain of these risks are discussed below.

The CIBM Direct Access Program is relatively new. Laws, rules, regulations, policies, notices, circulars or guidelines relating to the CIBM Direct Access Program as published or applied by the PBOC and other PRC authorities are relatively untested and are subject to change from time to time. There can be no assurance that the CIBM Direct Access Program will not be restricted, suspended or abolished. If such event occurs, the Fund’s ability to invest in the CIBM through the CIBM Direct Access Program will be adversely affected, and if the Fund is unable to adequately access the CIBM through other means, the Fund’s ability to achieve its investment objective will be adversely affected.

Under the prevailing PRC regulations, eligible foreign institutional investors who wish to invest directly in CIBM through the CIBM Direct Access Program may do so through an onshore settlement agent, who would be responsible for making the relevant filings and account opening with the relevant authorities. The Fund is therefore subject to the risk of default or errors on the part of such agent.

RQFII Investment Risk. Investment companies, such as the Fund, are not currently within the types of entities that are eligible for a Renminbi Qualified Foreign Institutional Investor (“RQFII”) or Qualified Foreign Institutional Investor (“QFII”) license. Rather, the Fund may utilize the Adviser’s RQFII license granted under RQFII regulations to invest in China bonds.

It is possible that the Adviser’s RQFII status could be suspended or revoked. Pursuant to PRC and RQFII regulations, the State Administration of Foreign Exchange (“SAFE”) and the China Securities Regulatory Commission (“CSRC”) are vested with the power to impose regulatory sanctions if the Adviser, in its capacity as RQFII, or the PRC custodian violates any provision of the RQFII regulations. Any such violations could result in the revocation of the Adviser’s RQFII license or other regulatory sanctions and may adversely affect the ability of the Fund to invest in China bonds. The Adviser is also subject to regulation by certain Hong Kong regulatory authorities, including the Hong Kong Securities and Futures Commission. Regulatory matters arising from such regulation could also adversely affect the Adviser’s RQFII license and ability to provide advisory services, generally.

There can be no assurance that the Adviser will continue to maintain its RQFII status. In the event the Adviser is unable to maintain its RQFII status, it may be necessary for the Fund to limit or suspend creations of Creation Units. In such event it is possible that the trading price of the Fund’s Shares on its Exchange will be at a significant premium to the NAV (which may also increase tracking error of the Fund). In extreme circumstances, the Fund may incur significant loss due to limited investment capabilities, or may not be able fully to implement or pursue its investment objectives or strategies, due to RQFII investment restrictions, illiquidity of the PRC securities markets, and delay or disruption in execution of trades or in settlement of trades.

The regulations which regulate investments by RQFIIs in the PRC and the repatriation of capital from RQFII investments are relatively new. The application and interpretation of such investment regulations are therefore relatively untested and there is no certainty as to how they will be applied as the PRC authorities and regulators have been given wide discretion in such investment regulations and there is no precedent or certainty as to how such discretion may be exercised now or in the future. Existing RQFII regulations may change over time and new RQFII regulations may be promulgated in the future and no assurance can be given that any such changes will not adversely affect the Fund or its ability to achieve its investment objective.

Bond Connect Risks. The “Mutual Bond Market Access between Mainland China and Hong Kong” (“Bond Connect”) program is a new initiative established by PBOC, China Foreign Exchange Trade System & National Interbank Funding Centre (“CFETS”), CCDC, SHCH, and Hong Kong Exchanges and Clearing Limited (“HKEx”) and Central Moneymarkets Unit (“CMU”) of the Hong Kong Monetary Authority (“HKMA”) to facilitate investor’s investments between the Mainland China and Hong Kong bond markets through connection between the Mainland China and Hong Kong financial institutions.

Under the prevailing PRC regulations, eligible foreign investors are allowed to invest in the bonds available on the CIBM through the northbound trading of Bond Connect (“Northbound Trading Link”). There is currently no investment quota for the Northbound Trading Link. The Northbound Trading Link refers to the trading platform that is located outside of Mainland China and is connected to CFETS for eligible foreign investors to submit their trade requests for bonds circulated in the CIBM through Bond Connect. HKEx and CFETS work together with offshore electronic bond trading platforms to provide electronic trading services and platforms to allow direct trading between eligible foreign investors and approved onshore dealers in Mainland China through CFETS. Under the Northbound Trading Link, eligible foreign investors are required to appoint the CFETS or other institutions recognized by the PBOC as registration agents to apply for registration with the PBOC.

Pursuant to the prevailing regulations in Mainland China, the CMU, the offshore custody agent recognized by the HKMA, opens omnibus nominee accounts with the onshore custody agent recognized by the PBOC (i.e., the CCDC and SHCH). All bonds traded by eligible foreign investors will be registered in the name of the CMU, which will hold such bonds as a nominee owner.

Bond Connect is relatively new. Laws, rules, regulations, policies, notices, circulars or guidelines relating to Bond Connect as published or applied by any of the Bond Connect Authorities (as defined below) are relatively untested and are subject to change. “Bond Connect Authorities” refers to the exchanges, trading systems, settlement systems, governmental, regulatory or tax bodies which provide services and/or regulate Bond Connect and activities relating to Bond Connect, including, without limitation, the PBOC, the HKMA, the HKEx, the CFETS, the CMU, the CCDC and the SHCH and any other regulator, agency or authority with jurisdiction, authority or responsibility in respect of Bond Connect. There can be no assurance that Bond Connect will not be restricted, suspended or abolished. If such event occurs, the Fund’s ability to invest in the CIBM through Bond Connect may be adversely affected, and if the Fund is unable to adequately access the CIBM through other means, the Fund’s ability to achieve its investment objective may be adversely affected.

Under the prevailing Bond Connect regulations, eligible foreign investors who wish to participate in Bond Connect may do so through an offshore custody agent, registration agent or other third parties (as the case may be), who would be responsible for making the relevant filings and account opening with the relevant authorities. The Fund is therefore subject to the risk of default or errors on the part of such agents.

Trading through Bond Connect is performed through newly developed trading platforms and operational systems. There is no assurance that such systems will function properly (in particular, under extreme market conditions) or will continue to be adapted to changes and developments in the market. In the event that the relevant systems fail to function properly, trading through Bond Connect may be disrupted. The Fund’s ability to trade through Bond Connect (and hence to pursue its investment strategy) may therefore be adversely affected. In addition, where the Fund invests in the CIBM through Bond Connect, it may be subject to risks of delays inherent in the order placing and/or settlement.

The CMU is the “nominee holder” of the bonds acquired by the Fund through Bond Connect. While Bond Connect Authorities have expressly stated that investors will enjoy the rights and interests of the bonds acquired through Bond Connect similar to investors in bond interests acquired through more traditional means in accordance with applicable laws, the exercise and the enforcement of beneficial ownership rights in such bonds in the Chinese courts has yet to be tested. As a result, for example, though the HKMA has stated otherwise in its Frequently Asked Questions relating to Bond Connect, it is possible that in the event that the nominee holder becomes insolvent, such bonds may be deemed to form part of the pool of assets of the nominee holder available for distribution to its creditors thereby subjugating the rights of the Fund.

Chinese Credit Rating Risks. China bonds will generally be rated by Chinese ratings agencies (and not by U.S. nationally recognized statistical ratings organizations (“NRSROs”)). The rating criteria and methodology used by Chinese rating agencies may be different from those adopted by NRSROs and international credit rating agencies. Therefore, such rating systems may not provide an equivalent standard for comparison with securities rated by NRSROs and international credit rating agencies.

Market Risks. The Fund investing in the CIBM will be subject to liquidity and volatility risks. Market volatility and potential lack of liquidity due to possible low trading volume of certain bonds in the CIBM may result in prices of certain bonds traded in the CIBM fluctuating significantly. The bid and offer spreads of the prices of such bonds may be large, and the Fund may therefore incur significant trading and realization costs and may even suffer losses when selling such investments. To the extent that the Fund transacts in the CIBM, the Fund may also be exposed to risks associated with settlement procedures and default of counterparties. The counterparty which has entered into a transaction with the Fund may default in its obligation to settle the transaction by failure to deliver relevant securities or to make payment.

Economic, Political and Social Risks of the PRC. The economy of China, which has been in a state of transition from a planned economy to a more market oriented economy, differs from the economies of most developed countries in many respects, including the level of government involvement, its state of development, its growth rate, control of foreign exchange, protection of intellectual property rights and allocation of resources.

Although the majority of productive assets in China are still owned by the PRC government at various levels, in recent years, the PRC government has implemented economic reform measures emphasizing utilization of market forces in the development of the economy of China and a high level of management autonomy. The economy of China has experienced significant growth in the past several decades, but growth has been uneven both geographically and among various sectors of the economy, and no assurance can be given that such growth will continue. Economic growth has also been accompanied by periods of high inflation. The PRC government has implemented various measures from time to time to control inflation and restrain the rate of economic growth.

There can, however, be no assurance that the PRC government will continue to pursue such economic policies or, if it does, that those policies will continue to be successful. Any such adjustment and modification of those economic policies may have an adverse impact on the securities markets in the PRC as well as the portfolio securities of the Fund. Further, the PRC government may from time to time adopt corrective measures to control the growth of the PRC economy, which may also have an adverse impact on the capital growth and performance of the Fund. Political changes, social instability and adverse diplomatic developments in the PRC could result in the imposition of additional government restrictions, including expropriation of assets, confiscatory taxes, limits on repatriation, or nationalization of some or all of the property held by the underlying issuers of the Fund’s portfolio securities.

PRC Laws and Regulations Risk. The regulatory and legal framework for capital markets and companies in the PRC may not be as well developed as those of developed countries. PRC laws and regulations affecting securities markets are relatively new and evolving, and because of the limited volume of published cases and judicial interpretation and their non-binding nature, interpretation and enforcement of these regulations involve significant uncertainties. In addition, as the PRC legal system develops, no assurance can be given that changes in such laws and regulations or new laws, regulations or practices relating to transactions in Chinese securities will be promulgated, or that their interpretation or enforcement will not have a material adverse effect on the Fund’s portfolio securities.

PRC Tax Risk. Uncertainties in PRC tax rules governing taxation of income and gains from investments in China bonds could result in unexpected tax liabilities for the Fund. The Fund’s investments in China bonds may cause the Fund to become subject to withholding and other taxes imposed by the PRC. The Ministry of Finance of the PRC and the State Administration of Taxation of the PRC issued Caishui No. 108 on November 7, 2018, which states that bond interests derived from investment in the China bond market (including through CIBM, a RQFII/QFII license or Bond Connect) by foreign investors will be temporarily exempt from withholding income tax and value added tax. The temporary exemption will remain in effect until November 6, 2021. If, in the future, China begins applying tax rules regarding the taxation of investment in China bonds by foreign investors, and/or begins collecting withholding and other taxes on interest derived by such investment, the Fund’s return might be adversely affected.

An investment in a Fund may be subject to a number of actual or potential conflicts of interest. For example, the Adviser or its affiliates may provide services to a Fund, such as securities lending agency services, custodial, administrative, bookkeeping, and accounting services, transfer agency and shareholder servicing, securities brokerage services, and other services for which the Fund would compensate the Adviser and/or such affiliates. A Fund may invest in other pooled investment vehicles sponsored, managed, or

otherwise affiliated with the Adviser. There is no assurance that the rates at which a Fund pays fees or expenses to the Adviser or its affiliates, or the terms on which it enters into transactions with the Adviser or its affiliates, will be the most favorable available in the market generally or as favorable as the rates the Adviser makes available to other clients. Because of its financial interest, the Adviser may have an incentive to enter into transactions or arrangements on behalf of a Fund with itself or its affiliates in circumstances where it might not have done so in the absence of that interest.

The method by which Creation Units of Shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of Shares are issued and sold by the Trust on an ongoing basis, at any point a “distribution,” as such term is used in the Securities Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent Shares, and sells such Shares directly to customers, or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for Shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in Shares, whether or not participating in the distribution of Shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(a)(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus-delivery obligation with respect to Shares of a Fund are reminded that under Securities Act Rule 153, a prospectus-delivery obligation under Section 5(b)(2) of the Securities Act owed to an exchange member in connection with a sale on the Exchange is satisfied by the fact that a Fund’s Prospectus is available at the Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is only available with respect to transactions on an exchange.

SSGA or its affiliates (the “Selling Shareholder”) may purchase Creation Units through a broker-dealer to “seed” (in whole or in part) Funds as they are launched, or may purchase shares from broker-dealers or other investors that have previously provided “seed” for Funds when they were launched or otherwise in secondary market transactions, and because the Selling Shareholder may be deemed an affiliate of such Funds, the Shares are being registered to permit the resale of these shares from time to time after purchase. The Funds will not receive any of the proceeds from the resale by the Selling Shareholders of these Shares.

The Selling Shareholder intends to sell all or a portion of the Shares owned by it and offered hereby from time to time directly or through one or more broker-dealers, and may also hedge such positions. The Shares may be sold on any national securities exchange on which the Shares may be listed or quoted at the time of sale, in the over-the-counter market or in transactions other than on these exchanges or systems at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in transactions, which may involve cross or block transactions.

The Selling Shareholder may also loan or pledge Shares to broker-dealers that in turn may sell such Shares, to the extent permitted by applicable law. The Selling Shareholder may also enter into options or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of Shares, which Shares such broker-dealer or other financial institution may resell.

The Selling Shareholder and any broker-dealer or agents participating in the distribution of Shares may be deemed to be “underwriters” within the meaning of Section 2(11) of the Securities Act in connection with such sales. In such event, any commissions paid to any such broker-dealer or agent and any profit on the resale of the Shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The Selling Shareholder who may be deemed an “underwriter” within the meaning of Section 2(11) of the Securities Act will be subject to the applicable prospectus delivery requirements of the Securities Act.

Counterparty risk with respect to derivatives has been and may continue to be affected by new rules and regulations affecting the derivatives market. Some derivatives transactions are required to be centrally cleared, and a party to a cleared derivatives transaction is subject to the credit risk of the clearing house and the clearing member through which it holds its cleared position, rather than the credit risk of its original counterparty to the derivatives transaction. Credit risk of market participants with respect to derivatives that are centrally cleared is concentrated in a few clearing houses, and it is not clear how an insolvency proceeding of a clearing house would be conducted, what effect the insolvency proceeding would have on any recovery by a Fund, and what impact an insolvency of a clearing house would have on the financial system more generally.

There can be no assurance that a liquid secondary market will exist for any particular futures contract or option at any specific time. Thus, it may not be possible to close a futures or options position. In the event of adverse price movements, a Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if a Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, a Fund may be required to make delivery of the instruments underlying futures contracts it has sold.

Each Fund will minimize the risk that it will be unable to close out a futures or options contract by only entering into futures and options for which there appears to be a liquid secondary market.

The risk of loss in trading futures contracts or uncovered call options in some strategies (e.g., selling uncovered index futures contracts) is potentially unlimited. The Funds do not plan to use futures and options contracts, when available, in this manner. The risk of a futures position may still be large as traditionally measured due to the low margin deposits required. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. A Fund, however, may utilize futures and options contracts in a manner designed to limit its risk exposure to that which is comparable to what it would have incurred through direct investment in securities.

Utilization of futures transactions by a Fund involves the risk of imperfect or even negative correlation to its benchmark Index if the index underlying the futures contracts differs from the benchmark Index or if the futures contracts do not track the benchmark Index as expected. There is also the risk of loss by a Fund of margin deposits in the event of bankruptcy of a broker with whom a Fund has an open position in the futures contract or option.

Certain financial futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. The daily limit governs only price movement during a particular trading day and therefore does not limit potential losses, because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.

Swap agreements are subject to the risk that the swap counterparty will default on its obligations. If such a default occurs, a Fund will have contractual remedies pursuant to the agreements related to the transaction, but such remedies may be subject to bankruptcy and insolvency laws which could affect the Fund’s rights as a creditor.

The use of interest-rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. The use of a swap requires an understanding not only of the referenced asset, reference rate or index but also of the swap itself, without the benefit of observing the performance of the swap under all possible market conditions. These transactions generally do not involve the delivery of securities or other underlying assets or principal.

The absence of a regulated execution facility or contract market and lack of liquidity for swap transactions has led, in some instances, to difficulties in trading and valuation, especially in the event of market disruptions. Under recently adopted rules and regulations, transactions in some types of swaps are required to be centrally cleared. In a cleared derivatives transaction, a Fund’s counterparty to the transaction is a central derivatives clearing organization, or clearing house, rather than a bank or broker. Because each Fund is not a member of a clearing house, and only members of a clearing house can participate directly in the clearing house, the Fund holds cleared derivatives through accounts at clearing members. In cleared derivatives transactions, a Fund will make payments (including margin payments) to and receive payments from a clearing house through its accounts at clearing members. Clearing members guarantee performance of their clients’ obligations to the clearing house. Centrally cleared derivative arrangements may be less favorable to a Fund than bilateral (non-cleared) arrangements. For example, a Fund may be required to provide greater amounts of margin for cleared derivatives transactions than for bilateral derivatives transactions. Also, in contrast to bilateral derivatives transactions, in some cases following a period of notice to a Fund, a clearing member generally can require termination of existing cleared derivatives transactions at any time or an increase in margin requirements above the margin that the clearing member required at the beginning of a transaction. Clearing houses also have broad rights to increase margin requirements for existing transactions or to terminate transactions at any time. A Fund is subject to risk if it enters into a derivatives transaction that is required to be cleared (or which SSGA FM expects to be cleared), and no clearing member is willing or able to clear the transaction on the Fund’s behalf. In that case, the transaction might have to be terminated, and the Fund could lose some or all of the benefit of the transaction, including loss of an increase in the value of the transaction and loss of hedging protection. In addition, the documentation governing the relationship between a Fund and clearing members is drafted by the clearing members and generally is less favorable to the Fund than typical bilateral derivatives documentation.

These clearing rules and other new rules and regulations could, among other things, restrict a Fund’s ability to engage in, or increase the cost to the Fund of, derivatives transactions, for example, by making some types of derivatives no longer available to the Fund, increasing margin or capital requirements, or otherwise limiting liquidity or increasing transaction costs. These regulations are new and evolving, so their potential impact on a Fund and the financial system are not yet known.

Because they are two party contracts that may be subject to contractual restrictions on transferability and termination and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid and subject to a Fund’s limitation on investments in illiquid securities. To the extent that a swap is not liquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses. Like most other investments, swap agreements are subject to the risk that the market value of the instrument will change in a way detrimental to a Fund’s interest.

If a Fund uses a swap as a hedge against, or as a substitute for, a portfolio investment, the Fund will be exposed to the risk that the swap will have or will develop imperfect or no correlation with the portfolio investment. This could cause substantial losses for the Fund. While hedging strategies involving swap instruments can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other Fund investments. Many swaps are complex and often valued subjectively.

A number of countries in Europe, including Greece, Spain, Ireland, Italy, and Portugal, have experienced rising government debt levels. The concern over these debt levels has led to volatility in the European financial markets, which has adversely affected the exchange rate of the euro and may continue to significantly affect every country in Europe. For some countries, the ability to repay sovereign debt is in question, and default is possible, which could affect their ability to borrow in the future. Several countries have agreed to multi-year bailout loans from the European Central Bank, the IMF, and other institutions. A default or debt restructuring by any European country can adversely impact holders of that country’s debt and can affect exposures to other EU countries and their financial companies as well. These financial difficulties may continue, worsen or spread within or outside Europe. Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not work, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences.

Uncertainties regarding the viability of the EU have impacted and may continue to impact markets in the United States and around the world. On January 31, 2020, the United Kingdom formally withdrew from the EU (commonly referred to as “Brexit”) and entered an 11-month transition period during which the United Kingdom remained part of the EU single market and customs union, the laws of which governed the economic, trade, and security relations between the United Kingdom and EU. The transition period concluded on December 31, 2020, and the United Kingdom left the EU single market and customs union under the terms of a new trade agreement. The agreement governs the new relationship between the United Kingdom and EU with respect to trading goods and services, but critical aspects of the relationship remain unresolved and subject to further negotiation and agreement. The full scope and nature of the consequences of the exit are not at this time known and are unlikely to be known for a significant period of time. It is also unknown whether the United Kingdom’s exit will increase the likelihood of other countries also departing the EU. Any additional exits from the EU, or the possibility of such exits, may have a significant impact on the United Kingdom, Europe, and global economies, which may result in increased volatility and illiquidity, new legal and regulatory uncertainties and potentially lower economic growth for such economies that could potentially have an adverse effect on the value of the Fund’s investments.

On July 27, 2017, the United Kingdom’s Financial Conduct Authority (FCA), which regulates LIBOR, announced that after 2021, it will cease its active encouragement of banks to provide quotations needed to sustain the LIBOR rate. On March 5, 2021, the administrator of LIBOR announced a delay in the phase out of the majority of the USD LIBOR publications until June 30, 2023, with the remainder of LIBOR publications to still end on December 31, 2021.

Various financial industry groups have begun planning for that transition, however, there remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement rate. The replacement or abandonment of, or modification to, LIBOR could have adverse impacts on newly issued financial instruments and existing financial instruments which reference LIBOR. While some instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate setting methodology, not all instruments may have such provisions and there are significant uncertainty regarding the effectiveness of any such alternative methodologies. Abandonment of or modifications to LIBOR could lead to significant short-term and long-term uncertainty and market instability and the extent to which that may impact a Fund may vary depending on various factors, which include, but are not limited to: (i) existing fallback or termination provisions in individual contracts and (ii) whether, how, and when industry participants develop and adopt new successor reference rates and/or fallbacks for both legacy and new instruments. In addition, the transition to a successor rate could potentially cause (i) increased volatility or illiquidity in markets for instruments that currently rely on LIBOR, (ii) a reduction in the value of certain instruments held by a Fund, or (iii) reduced effectiveness of related Fund transactions, such as

hedging. It remains uncertain how such changes would be implemented and the effects such changes would have on a Fund, issuers of instruments in which a Fund invests and financial markets generally. Instruments in which the Fund invests may pay interest at floating or adjusting rates based on LIBOR or may be subject to interest caps or floors. There remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement rate. The unavailability or replacement of LIBOR may affect the value, liquidity or return on certain Fund investments and may result in costs incurred in connection with closing out positions and entering into new trades. Any pricing adjustments to a Fund’s investments resulting from a substitute reference rate may also adversely affect the Fund’s performance and/or NAV. Such successor or substitute reference rate and any adjustments selected may negatively impact a Fund’s investments, performance or financial condition, and may expose the Fund to additional tax, accounting and regulatory risks, Additionally, if LIBOR ceases to exist, a Fund may need to renegotiate the credit agreements extending beyond the LIBOR phase out date with the Fund’s obligors that utilize LIBOR as a factor in determining the interest rate and certain of the Fund’s existing credit facilities to replace LIBOR with the new standard that is established. Any pricing adjustments to a Fund’s investments resulting from a substitute reference rate may also adversely affect the Fund’s performance and/or NAV. Such successor or substitute reference rate and any adjustments selected may negatively impact a Fund’s investments, performance or financial condition, and may expose the Fund to additional tax, accounting and regulatory risks.

The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, a steering committee comprised of large U.S. financial institutions, intends to replace the U.S. dollar LIBOR with the Secured Overnight Financing Rate (SOFR), a new index calculated by short-term repurchase agreements, backed by Treasury securities. Abandonment of or modifications to LIBOR could have adverse impacts on newly issued financial instruments and existing financial instruments which reference LIBOR. While some instruments may contemplate a scenario where LIBOR is no longer available by providing for an alternative rate setting methodology, not all instruments may have such provisions and there are significant uncertainty regarding the effectiveness of any such alternative methodologies.

In 2012, regulators in the United States and the United Kingdom alleged that some of the member banks surveyed by the British Bankers Association engaged in manipulative acts in connection with the calculation of LIBOR. Several financial institutions have reached settlements with the CFTC, the U.S. Department of Justice Fraud Section and FCA in connection with investigations by such authorities into submissions made by such financial institutions to the bodies that set LIBOR and other interbank offered rates. Additional investigations remain ongoing with respect to other major banks. Despite increased regulation and other corrective actions since that time, concerns have arisen regarding LIBOR’s viability as a benchmark, due to decreased confidence of the market in LIBOR and lead market participants looking for alternative, non-LIBOR based types of financing, such as fixed rate loans or bonds or floating rate loans based on non-LIBOR indices.

An outbreak of a respiratory disease caused by a novel coronavirus first detected in China in December 2019 has spread globally in a short period of time. In an organized attempt to contain and mitigate the effects of the spread of the coronavirus known as COVID-19, governments and businesses world-wide have taken aggressive measures, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines of large populations. COVID-19 has resulted in the disruption of and delays in the delivery of healthcare services and processes, the cancellation of organized events and educational institutions, the disruption of production and supply chains, a decline in consumer demand for certain goods and services, and general concern and uncertainty, all of which have contributed to increased volatility in global markets. The effects of COVID-19 will likely affect certain sectors and industries more dramatically than others, which may adversely affect the value of a Fund’s investments in those sectors or industries. COVID-19, and other epidemics and pandemics that may arise in the future, could adversely affect the economies of many nations, the global economy, individual companies and capital markets in ways that cannot be foreseen at the present time. In addition, the impact of infectious diseases in developing or emerging market countries may be greater due to limited health care resources. Political, economic and social stresses caused by COVID-19 also may exacerbate other pre-existing political, social and economic risks in certain countries. The duration of COVID-19 and its effects cannot be determined at this time, but the effects could be present for an extended period of time.

As with any investment, you should consider how your investment in Shares of a Fund will be taxed. The tax information in the Prospectus and this SAI is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares of a Fund.

Unless your investment in Shares is made through a tax-exempt entity or tax-advantaged retirement account, such as an individual retirement account, you need to be aware of the possible tax consequences when a Fund makes distributions or you sell Shares.

The S&P Kensho New Economies Composite Index is comprised of U.S.-listed equity securities (including depositary receipts) of companies domiciled across developed and emerging markets worldwide. The Index is designed to capture companies whose products and services are driving innovation and transforming the global economy through the use of existing and emerging technologies, and

rapid developments in robotics, automation, artificial intelligence, connectedness and processing power (“New Economies companies”). In particular, the Index comprises the components included in the New Economy Subsector Indexes (each, an “Underlying Index”) developed by Kensho Technologies, Inc. Each Underlying Index is comprised of securities of New Economies companies in a specific sector. As of the date of this SAI, the Underlying Indexes include S&P Kensho Advanced Transport Systems Index, S&P Kensho Wearables Index, S&P Kensho Robotics Index, S&P Kensho Autonomous Vehicles Index, S&P Kensho Cleantech Index, S&P Kensho Cyber Security Index, S&P Kensho 3D Printing Index, S&P Kensho Smart Borders Index, S&P Kensho Genetic Engineering Index, S&P Kensho Drones Index, S&P Kensho Clean Energy Index, S&P Kensho Smart Grids Index, S&P Kensho Smart Buildings Index, S&P Kensho Space Index, S&P Kensho Nanotechnology Index, S&P Kensho Virtual Reality Index, S&P Kensho Future Payments Index, S&P Kensho Enterprise Collaboration Index, S&P Kensho Electric Vehicles Index, S&P Kensho Alternative Finance Index, S&P Kensho Digital Communities Index, and S&P Kensho Distributed Ledger Index.

The Trust has adopted the following investment restrictions as fundamental policies with respect to each Fund. These restrictions cannot be changed without the approval of the holders of a majority of a Fund’s outstanding voting securities. For purposes of the 1940 Act, a majority of the outstanding voting securities of a Fund means the vote, at an annual or a special meeting of the security holders of the Trust, of the lesser of (1) 67% or more of the voting securities of the Fund present at such meeting, if the holders of more than 50% of the outstanding voting securities of the Fund are present or represented by proxy, or (2) more than 50% of the outstanding voting securities of the Fund. Except with the approval of a majority of the outstanding voting securities, each Fund may not:

In addition to the investment restrictions adopted as fundamental policies as set forth above, each Fund observes the following restrictions, which may be changed by the Board without a shareholder vote. Each Fund will not:

The Funds define the foregoing terms in accordance with the definition of such terms per the applicable Index. If a percentage limitation is adhered to at the time of investment or contract, a later increase or decrease in percentage resulting from any change in value or total or net assets will not result in a violation of such restriction, except that the percentage limitations with respect to the borrowing of money will be observed continuously. With respect to the limitation on borrowing, in the event that a subsequent change in net assets or other circumstances cause a Fund to exceed its limitation, the Fund will take steps to bring the aggregate amount of borrowing back within the limitations within three days thereafter (not including Sundays and holidays).

The 1940 Act currently permits each Fund to loan up to 33 1/3% of its total assets. With respect to borrowing, the 1940 Act presently allows each Fund to: (1) borrow from any bank (including pledging, mortgaging or hypothecating assets) in an amount up to 33 1/3% of its total assets, (2) borrow money for temporary purposes in an amount not exceeding 5% of the value of the Fund’s total assets at the time of the loan, and (3) enter into reverse repurchase agreements. However, under normal circumstances any borrowings by a Fund will not exceed 10% of the Fund’s total assets. The 1940 Act generally prohibits funds from issuing senior securities, although it does not treat certain transactions as senior securities, such as certain borrowings, short sales, reverse repurchase agreements, firm commitment agreements and standby commitments, with appropriate earmarking or segregation of assets to cover such obligation. With respect to investments in commodities, the 1940 Act presently permits the Funds to invest in commodities in accordance with investment policies contained in its prospectus and SAI. Any such investment shall also comply with the CEA and the rules and regulations thereunder. The 1940 Act does not directly restrict an investment company’s ability to invest in real estate, but does require that every investment company have the fundamental investment policy governing such investments. The Funds will not purchase or sell real estate, except that a Fund may invest in companies that deal in real estate (including REITs) or in instruments that are backed or secured by real estate.

A discussion of exchange listing and trading matters associated with an investment in a Fund is contained in the Prospectus under “PURCHASE AND SALE INFORMATION” and “ADDITIONAL PURCHASE AND SALE INFORMATION.” The discussion below supplements, and should be read in conjunction with, such sections of the Prospectus.

The Shares of each Fund are approved for listing and trading on the Exchange, subject to notice of issuance. Shares trade on the Exchange at prices that may differ to some degree from their net asset value. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of Shares of a Fund will continue to be met.

The Exchange may consider the suspension of trading in, and may initiate delisting proceedings of, the Shares of a Fund under any of the following circumstances: (i) if the Exchange becomes aware that the Fund is no longer eligible to operate in reliance on Rule 6c-11 under the 1940 Act; (ii) if the Fund no longer complies with the applicable listing requirements set forth in the Exchange’s rules;

(iii) if, following the initial twelve-month period after commencement of trading on the Exchange of the Fund, there are fewer than 50 beneficial holders of the Fund; or (iv) if such other event shall occur or condition exists which, in the opinion of the Exchange, makes further dealings on the Exchange inadvisable. The Exchange will remove the Shares from listing and trading upon termination of a Fund.

The Trust reserves the right to adjust the Share price of a Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund or an investor’s equity interest in the Fund.

As in the case of other publicly traded securities, brokers’ commissions on transactions will be based on negotiated commission rates at customary levels.

The base and trading currencies of each Fund is the U.S. dollar. The base currency is the currency in which a Fund’s net asset value per Share is calculated and the trading currency is the currency in which Shares of a Fund are listed and traded on the Exchange.

The following information supplements and should be read in conjunction with the section in the Prospectus entitled “MANAGEMENT.”

Board Responsibilities. The management and affairs of the Trust and its series, including the Funds described in this SAI, are overseen by the Trustees. The Board has approved contracts, as described in this SAI, under which certain companies provide essential management services to the Trust.

Like most mutual funds, the day-to-day business of the Trust, including the management of risk, is performed by third party service providers, such as the Adviser, Sub-Advisers, Distributor, Administrator, and Sub-Administrator. The Trustees are responsible for overseeing the Trust’s service providers and, thus, have oversight responsibility with respect to risk management performed by those service providers. Risk management seeks to identify and address risks, i.e., events or circumstances that could have material adverse effects on the business, operations, shareholder services, investment performance or reputation of the Funds. The Funds and their service providers employ a variety of processes, procedures and controls to identify various of those possible events or circumstances, to lessen the probability of their occurrence and/or to mitigate the effects of such events or circumstances if they do occur. Each service provider is responsible for one or more discrete aspects of the Trust’s business (e.g., a Sub-Adviser is responsible for the day-to-day management of a Fund’s portfolio investments) and, consequently, for managing the risks associated with that business. The Board has emphasized to the Funds’ service providers the importance of maintaining vigorous risk management.

The Trustees’ role in risk oversight begins before the inception of a Fund, at which time the Fund’s Adviser and, if applicable, Sub-Adviser presents the Board with information concerning the investment objectives, strategies and risks of the Fund, as well as proposed investment limitations for the Fund. Additionally, the Fund’s Adviser and Sub-Adviser provide the Board with an overview of, among other things, their investment philosophies, brokerage practices and compliance infrastructures. Thereafter, the Board continues its oversight function as various personnel, including the Trust’s Chief Compliance Officer, as well as personnel of the Adviser and other service providers, such as the Fund’s independent accountants, make periodic reports to the Audit Committee or to the Board with respect to various aspects of risk management. The Board and the Audit Committee oversee efforts by management and service providers to manage risks to which a Fund may be exposed.

The Board is responsible for overseeing the nature, extent and quality of the services provided to the Funds by the Adviser and Sub-Adviser and receives information about those services at its regular meetings. In addition, on an annual basis, in connection with its consideration of whether to renew the Investment Advisory Agreement and Sub-Advisory Agreement with the Adviser and Sub-Adviser, respectively, the Board meets with the Adviser and Sub-Adviser to review such services. Among other things, the Board regularly considers the Adviser’s and Sub-Adviser’s adherence to the Fund’s investment restrictions and compliance with various Fund policies and procedures and with applicable securities regulations. The Board also reviews information about each Fund’s investments.

The Trust’s Chief Compliance Officer reports regularly to the Board to review and discuss compliance issues. At least annually, the Trust’s Chief Compliance Officer provides the Board with a report reviewing the adequacy and effectiveness of the Trust’s policies and procedures and those of its service providers, including the Adviser and any Sub-Adviser. The report addresses the operation of the policies and procedures of the Trust and each service provider since the date of the last report; any material changes to the policies and procedures since the date of the last report; any recommendations for material changes to the policies and procedures; and any material compliance matters since the date of the last report.

The Board receives reports from the Funds’ service providers regarding operational risks and risks related to the valuation and liquidity of portfolio securities. Regular reports are made to the Board concerning investments for which market quotations are not readily available. Annually, the independent registered public accounting firm reviews with the Audit Committee its audit of each Fund’s financial statements, focusing on major areas of risk encountered by the Funds and noting any significant deficiencies or material weaknesses in the Fund’s internal controls. Additionally, in connection with its oversight function, the Board oversees Fund management’s implementation of disclosure controls and procedures, which are designed to ensure that information required to be disclosed by the Trust in its periodic reports with the SEC are recorded, processed, summarized, and reported within the required time periods. The Board also oversees the Trust’s internal controls over financial reporting, which comprise policies and procedures designed to provide reasonable assurance regarding the reliability of the Trust’s financial reporting and the preparation of the Trust’s financial statements.

From their review of these reports and discussions with the Adviser and Sub-Adviser, the Chief Compliance Officer, the independent registered public accounting firm and other service providers, the Board and the Audit Committee learn in detail about the material risks of the Funds, thereby facilitating a dialogue about how management and service providers identify and mitigate those risks.

The Board recognizes that not all risks that may affect a Fund can be identified and/or quantified, that it may not be practical or cost-effective to eliminate or mitigate certain risks, that it may be necessary to bear certain risks (such as investment-related risks) to achieve a Fund’s goals, and that the processes, procedures and controls employed to address certain risks may be limited in their effectiveness. Moreover, reports received by the Trustees as to risk management matters are typically summaries of the relevant information. Most of the Funds’ investment management and business affairs are carried out by or through a Fund’s Adviser, Sub-Adviser and other service providers, each of which has an independent interest in risk management but whose policies and the methods by which one or more risk management functions are carried out may differ from the Funds’ and each other’s in the setting of priorities, the resources available or the effectiveness of relevant controls. As a result of the foregoing and other factors, the Board’s ability to monitor and manage risk, as a practical matter, is subject to limitations.

Trustees and Officers. There are five members of the Board of Trustees, four of whom are not interested persons of the Trust, as that term is defined in the 1940 Act (“Independent Trustees”). Carl Verboncoeur, an Independent Trustee, serves as Chairman of the Board. The Board has determined its leadership structure is appropriate given the specific characteristics and circumstances of the Trust. The Board made this determination in consideration of, among other things, the fact that the Independent Trustees constitute a super-majority (greater than 75%) of the Board, the fact that the chairperson of each Committee of the Board is an Independent Trustee, the amount of assets under management in the Trust, and the number of funds (and classes of shares) overseen by the Board. The Board also believes that its leadership structure facilitates the orderly and efficient flow of information to the Independent Trustees from fund management.

The Board of Trustees has two standing committees: the Audit Committee and Trustee Committee. The Audit Committee and Trustee Committee are each chaired by an Independent Trustee and composed of all of the Independent Trustees.

Set forth below are the names, year of birth, position with the Trust, length of term of office, and the principal occupations during the last five years and other directorships held of each of the persons currently serving as a Trustee or Officer of the Trust.

The Board has concluded that each of the Trustees should serve on the Board because of his or her ability to review and understand information about the Funds provided to him or her by management, to identify and request other information he or she may deem relevant to the performance of his or her duties, to question management and other service providers regarding material factors bearing on the management and administration of the Funds, and to exercise his or her business judgment in a manner that serves the best interests of each Fund’s shareholders. The Board has concluded that each of the Trustees should serve as a Trustee based on his or her own experience, qualifications, attributes and skills as described below.

The Board has concluded that Mr. Verboncoeur should serve as Trustee because of the experience he gained serving as the Chief Executive Officer of a large financial services and investment management company, his knowledge of the financial services industry and his experience serving on the boards of other investment companies. Mr. Verboncoeur was elected to serve as Trustee of the Trust in April 2010.

The Board has concluded that Mr. Churchill should serve as Trustee because of the experience he gained serving as the Head of the Fixed Income Division of one of the nation’s leading mutual fund companies and provider of financial services and his knowledge of the financial services industry. Mr. Churchill was elected to serve as Trustee of the Trust in April 2010.

The Board has concluded that Ms. Richer should serve as Trustee because of the experience she gained serving as the Chief Financial Officer of a large financial services and investment management company, her knowledge of the financial services industry and her experience serving on the board of a major educational institution. Ms. Richer was appointed to serve as Trustee of the Trust in July 2018.

The Board has concluded that Ms. Sponem should serve as Trustee because of the experience she gained serving as the Chief Financial Officer of a large financial services company, her knowledge of the financial services industry and her experience serving on the boards of other investment companies. Ms. Sponem was appointed to serve as Trustee of the Trust in July 2018.

The Board has concluded that Mr. Ross should serve as Trustee because of the experience he has gained in his various roles with the Adviser, his knowledge of the financial services industry, and the experience he has gained serving as Trustee of the Trust since 2005 (Mr. Ross did not serve as Trustee from December 2009 until April 2010).

In its periodic assessment of the effectiveness of the Board, the Board considers the complementary individual skills and experience of the individual Trustees primarily in the broader context of the Board’s overall composition so that the Board, as a body, possesses the appropriate (and appropriately diverse) skills and experience to oversee the business of the Funds.

No officer, director or employee of the Adviser, its parent or subsidiaries receives any compensation from the Trust for serving as an officer or Trustee of the Trust. The Trust, SSGA Active Trust and SPDR Index Shares Funds (together with the Trust, the “Trusts”) pay, in the aggregate, each Trustee an annual fee of $270,000 (prior to January 1, 2021, $245,000) plus $10,000 per in-person meeting attended and $1,250 for each telephonic or video conference meeting attended. The Chairman of the Board receives an additional annual fee of $75,000 (prior to January 1, 2021, $60,000) and the Chairman of the Audit Committee receives an additional annual fee of $30,000. The Trusts also reimburse each Trustee for travel and other out-of-pocket expenses incurred by him/her in connection with attending such meetings and in connection with attending industry seminars and meetings. Trustee fees are allocated between the Trusts and each of their respective series in such a manner as deemed equitable, taking into consideration the relative net assets of the series.

The table below shows the compensation that the Trustees received during the Funds’ fiscal year ended June 30, 2021.

Audit Committee. The Board has an Audit Committee consisting of all Independent Trustees. Mr. Churchill serves as Chairman. The Audit Committee meets with the Trust’s independent auditors to review and approve the scope and results of their professional services; to review the procedures for evaluating the adequacy of the Trust’s accounting controls; to consider the range of audit fees; and to make recommendations to the Board regarding the engagement of the Trust’s independent auditors. The Audit Committee met [four (4) times] during the fiscal year ended June 30, 2021.

Trustee Committee. The Board has established a Trustee Committee consisting of all Independent Trustees. Mr. Verboncoeur serves as Chairman. The responsibilities of the Trustee Committee are to: 1) nominate Independent Trustees; 2) review on a periodic basis the governance structures and procedures of the Funds; 3) review proposed resolutions and conflicts of interest that may arise in the business of the Funds and may have an impact on the investors of the Funds; 4) select any independent counsel of the independent trustees as well as make determinations as to that counsel’s independence; 5) review matters that are referred to the Committee by the Chief Legal Officer or other counsel to the Trust; and 6) provide general oversight of the Funds on behalf of the investors of the Funds. The Trustee Committee does not have specific procedures in place with respect to the consideration of nominees recommended by security holders, but may consider such nominees in the event that one is recommended. The Trustee Committee met [four (4) times] during the fiscal year ended June 30, 2021.

As of December 31, 2020, neither the Independent Trustees nor their immediate family members owned beneficially or of record any securities in the Adviser, Sub-Advisers, Principal Underwriter or any person directly or indirectly controlling, controlled by, or under common control with the Adviser, Sub-Adviser or Principal Underwriter.

The following table shows, as of December 31, 2020, the amount of equity securities beneficially owned by the Trustees in the Trust.

The Trust, the Adviser (which includes applicable reporting personnel of the Distributor) and the Sub-Advisers each have adopted a Code of Ethics pursuant to Rule 17j-1 of the 1940 Act, which is designed to prevent affiliated persons of the Trust, the Adviser, the Sub-Advisers and the Distributor from engaging in deceptive, manipulative or fraudulent activities in connection with securities held or to be acquired by the Funds (which may also be held by persons subject to the Codes of Ethics). Each Code of Ethics permits personnel, subject to that Code of Ethics, to invest in securities for their personal investment accounts, subject to certain limitations, including securities that may be purchased or held by the Funds.

There can be no assurance that the Codes of Ethics will be effective in preventing such activities. Each Code of Ethics, filed as exhibits to this registration statement, may be examined at the office of the SEC in Washington, D.C. or on the Internet at the SEC’s website at https://www.sec.gov.

The Board believes that the voting of proxies on securities held by each Fund is an important element of the overall investment process. As such, the Board has delegated the responsibility to vote such proxies to the Adviser for all Funds, other than the Municipal Bond ETFs, for which proxy voting (to the extent applicable) has been delegated to the sub-adviser Nuveen Asset Management, LLC (“Nuveen Asset Management”). Each of the Trust’s and the Adviser’s proxy voting policy is attached at the end of this SAI. Information regarding how a Fund voted proxies relating to its portfolio securities during the most recent twelve-month period ended June 30 is available: (1) without charge by calling 1-866-787-2257; (2) on the Funds’ website at https://www.ssga.com/spdrs; and (3) on the SEC’s website at https://www.sec.gov.

The Municipal Bond ETFs invest their assets primarily in municipal bonds and cash management securities, which typically do not issue proxies. On rare occasions a Fund may acquire, directly or through a special purpose vehicle, securities of a municipal bond issuer whose bonds the Fund already owns when such bonds have deteriorated or are expected shortly to deteriorate significantly in credit quality. The purpose of acquiring equity securities generally will be to seek to maximize the value of the existing holdings, prevent the credit deterioration or facilitate the liquidation or other workout of the distressed issuer’s credit problem. In the course of these activities, Nuveen Asset Management may pursue the Fund’s interests in a variety of ways, which may entail negotiating and executing consents, agreements and other arrangements, and otherwise influencing the management of the issuer. Nuveen Asset Management does not consider such activities proxy voting for purposes of Rule 206(4)-6 under the Investment Advisers Act of 1940, as amended.

In the rare event that a municipal issuer were to issue a proxy or that a Fund were to receive a proxy issued by a cash management security, Nuveen Asset Management would either engage an independent third party to determine how the proxy should be voted or vote the proxy with the consent, or based on the instructions, of the Fund’s Board or its representative. A member of Nuveen Asset Management’s legal department would oversee the administration of the voting, and ensure that records were maintained in accordance with Rule 206(4)-6, reports were filed with the SEC on Form N-PX, and the results provided to the Fund’s Board and made available to shareholders as required by applicable rules.

The Trust has adopted a policy regarding the disclosure of information about the Trust’s portfolio holdings. The Board must approve all material amendments to this policy. The Funds’ portfolio holdings are publicly disseminated each day a Fund is open for business through financial reporting and news services including publicly accessible Internet web sites. In addition, a basket composition file, which includes the security names and share quantities to deliver in exchange for Shares, together with estimates and actual cash components, is publicly disseminated daily prior to the opening of the Exchange via the National Securities Clearing Corporation (“NSCC”). The basket represents one Creation Unit of a Fund. The Trust, the Adviser, the Sub-Advisers or State Street will not disseminate non-public information concerning the Trust, except information may be made available prior to its public availability: (i) to a party for a legitimate business purpose related to the day-to-day operations of the Funds including (a) a service provider, (b) the stock exchanges upon which an ETF is listed, (c) the NSCC, (d) the Depository Trust Company, and (e) financial data/research companies such as Morningstar, Bloomberg L.P., and Reuters, or (ii) to any other party for a legitimate business or regulatory purpose, upon waiver or exception, with the consent of an applicable Trust officer.

SSGA FM acts as investment adviser to the Trust and, subject to the oversight of the Board, is responsible for the investment management of each Fund. As of June 30, 2021, the Adviser managed approximately $[ ] billion in assets. The Adviser’s principal address is One Iron Street, Boston, Massachusetts 02210. The Adviser, a Massachusetts corporation, is a wholly-owned subsidiary of State Street Global Advisors, Inc., which is itself a wholly-owned subsidiary of State Street Corporation, a publicly held financial holding company. State Street Global Advisors (“SSGA”), consisting of the Adviser and other investment advisory affiliates of State Street Corporation, is the investment management arm of State Street Corporation.

The Adviser serves as investment adviser to each Fund pursuant to an investment advisory agreement (“Investment Advisory Agreement”) between the Trust and the Adviser. The Investment Advisory Agreement, with respect to each Fund, continues in effect for two years from its effective date, and thereafter is subject to annual approval by (1) the Board or (2) vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund, provided that in either event such continuance also is approved by a majority of the Board who are not interested persons (as defined in the 1940 Act) of the Trust by a vote cast in person at a meeting called for the purpose of voting on such approval. The Investment Advisory Agreement with respect to each Fund is terminable without penalty, on 60 days’ notice, by the Board or by a vote of the holders of a majority (as defined in the 1940 Act) of a Fund’s outstanding voting securities. The Investment Advisory Agreement is also terminable upon 60 days’ notice by the Adviser and will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Under the Investment Advisory Agreement, the Adviser, subject to the oversight of the Board and in conformity with the stated investment policies of each Fund, manages the investment of each Fund’s assets. The Adviser is responsible for placing purchase and sale orders and providing continuous supervision of the investment portfolio of each Fund. Pursuant to the Investment Advisory Agreement, the Adviser is not liable for certain liabilities, including certain liabilities arising under the federal securities laws, unless such loss or liability results from willful misfeasance, bad faith or gross negligence in the performance of its duties or the reckless disregard of its obligations and duties.

Under the Advisory Agreement, the Adviser performs certain oversight and supervisory functions with respect to Nuveen Asset Management as sub-adviser to the Municipal Bond ETFs, including: (i) conduct periodic analysis and review of the performance by Nuveen Asset Management of its obligations to the Municipal Bond ETFs and provide periodic reports to the Board regarding such performance; (ii) review any changes to Nuveen Asset Management’s ownership, management, or personnel responsible for performing its obligations to the Municipal Bond ETFs; and make appropriate reports to the Board (iii) perform periodic due diligence meetings with representatives of Nuveen Asset Management; and (iv) assist the Board and management of the Trust, as applicable, concerning the initial approval, continued retention or replacement of Nuveen Asset Management as sub-adviser to the Municipal Bond ETFs.

A discussion regarding the basis for the Board’s approval of the continuation of the Investment Advisory Agreement regarding the Funds is available in the Trust’s Annual Report to Shareholders for the period ended June 30, 2021.

For the services provided to the Funds under the Investment Advisory Agreement, each Fund pays the Adviser monthly fees based on a percentage of each Fund’s average daily net assets as set forth in each Fund’s Prospectus. The Adviser pays all expenses of each Fund other than the management fee, brokerage, taxes, interest, fees and expenses of the Independent Trustees (including any Trustee’s counsel fees), acquired fund fees and expenses, litigation expenses and other extraordinary expenses.

For the past three fiscal years ended June 30, the Funds paid the following amounts to the Adviser:

From time to time, the Adviser may waive all or a portion of its fee. [The Adviser has contractually agreed to waive a portion of its management fee and/or reimburse expenses in an amount equal to any acquired fund fees and expenses (excluding holdings in acquired funds for cash management purposes, if any) for each Fund until October 31, 2022. Additionally, for certain Funds the Adviser has contractually agreed to waive a portion of its management fee and/or reimburse certain expenses, until October 31, 2022, so that the net annual Fund operating expenses, before application of any fees and expenses not paid by the Adviser pursuant to the Investment Advisory Agreement, if any, are limited to a percentage of a Fund’s average daily net assets, as indicated in the table below. Each contractual fee waiver and/or reimbursement does not provide for the recoupment by the Adviser of any fees the Adviser previously waived. The Adviser may continue each waiver and/or reimbursement from year to year, but there is no guarantee that the Adviser will do so and each waiver and/or reimbursement may be cancelled or modified at any time after October 31, 2022. Each waiver and/or reimbursement may not be terminated prior to October 31, 2022 except with the approval of the Board.]

Additionally, the Adviser has voluntarily agreed to waive a portion its management fee so that the total annual fund operating expenses of the [SPDR S&P 600 Small Cap ETF] do not exceed [0.05]% of its average daily net assets. The Adviser may, in its sole discretion, discontinue this voluntary waiver at any time without any prior notice.

Pursuant to the Advisory Agreement between the Funds and the Adviser, the Adviser is authorized to engage one or more sub-advisers for the performance of any of the services contemplated to be rendered by the Adviser. The Adviser has engaged the following sub-advisers.

The Adviser has retained Nuveen Asset Management as sub-adviser, to be responsible for the day to day management of the Municipal Bond ETFs’ investments, subject to supervision of the Adviser and oversight by the Board. The Adviser provides administrative, compliance and general management services to the Municipal Bond ETFs. Nuveen Asset Management offers advisory and investment management services to a broad range of mutual fund clients and has extensive experience in managing municipal securities. As of June 30, 2021, Nuveen Asset Management managed approximately $[ ] billion in assets. Nuveen Asset Management’s principal business address is [333 West Wacker Drive, Chicago, Illinois 60606]. Nuveen Asset Management is a subsidiary of Nuveen Fund Advisors, LLC, which is a subsidiary of Nuveen, LLC (“Nuveen”).

Nuveen is the asset management division of Teachers Insurance and Annuity Association of America (“TIAA”). TIAA is a leading financial services provider that provides a wide range of financial solutions, including investing, banking, advice and education, and retirement services. TIAA was originally founded in 1918 by the Carnegie Foundation for the Advancement of Teaching.

In accordance with the Sub-Advisory Agreement between the Adviser and Nuveen Asset Management, the Adviser pays Nuveen Asset Management an annual investment sub-advisory fee equal to 45% of the advisory fees paid by the Municipal Bond ETFs to the Adviser after deducting the payments to fund service providers and fund expenses. For the past three fiscal years ended June 30, the Adviser paid the following amounts to Nuveen Asset Management for its services:

A discussion regarding the basis for the Board’s approval of the Sub-Advisory Agreement is available in the Trust’s Annual Report to Shareholders for the period ending June 30, 2021.

The Adviser manages the Funds and Nuveen Asset Management manages the Municipal Bond ETFs using a team of investment professionals. The professionals primarily responsible for the day-to-day portfolio management of each Fund are:

All ETFs except Municipal Bond ETFs. The following table lists the number and types of accounts managed by each of the key professionals involved in the day-to-day portfolio management for each Fund and assets under management in those accounts. The total number of accounts and assets have been allocated to each respective manager. Therefore, some accounts and assets have been counted twice.

[None of the portfolio managers listed above beneficially owned Shares as of June 30, 2021, except as noted in the table below:]

A portfolio manager that has responsibility for managing more than one account may be subject to potential conflicts of interest because he or she is responsible for other accounts in addition to the Funds. Those conflicts could include preferential treatment of one account over others in terms of: (a) the portfolio manager’s execution of different investment strategies for various accounts; or (b) the allocation of resources or of investment opportunities.

Portfolio managers may manage numerous accounts for multiple clients. These accounts may include registered investment companies, other types of pooled accounts (e.g., collective investment funds), and separate accounts (i.e., accounts managed on behalf of individuals or public or private institutions). Portfolio managers make investment decisions for each account based on the investment objectives and policies and other relevant investment considerations applicable to that portfolio. A potential conflict of interest may arise as a result of the portfolio managers’ responsibility for multiple accounts with similar investment guidelines. Under these circumstances, a potential investment may be suitable for more than one of the portfolio managers’ accounts, but the quantity of the investment available for purchase is less than the aggregate amount the accounts would ideally devote to the opportunity. Similar conflicts may arise when multiple accounts seek to dispose of the same investment. The portfolio managers may also manage accounts whose objectives and policies differ from that of the Funds. These differences may be such that under certain circumstances, trading activity appropriate for one account managed by the portfolio manager may have adverse consequences for another account managed by the portfolio manager. For example, an account may sell a significant position in a security, which could cause the market price of that security to decrease, while a Fund maintained its position in that security.

A potential conflict may arise when the portfolio managers are responsible for accounts that have different advisory fees—the difference in fees could create an incentive for the portfolio manager to favor one account over another, for example, in terms of access to investment opportunities. Another potential conflict may arise when the portfolio manager has an investment in one or more accounts that participate in transactions with other accounts. His or her investment(s) may create an incentive for the portfolio manager to favor one account over another. The Adviser has adopted policies and procedures reasonably designed to address these potential material conflicts. For instance, portfolio managers are normally responsible for all accounts within a certain investment discipline, and do not, absent special circumstances, differentiate among the various accounts when allocating resources. Additionally, the Adviser and its advisory affiliates have processes and procedures for allocating investment opportunities among portfolios that are designed to provide a fair and equitable allocation.

SSGA’s culture is complemented and reinforced by a total rewards strategy that is based on a pay for performance philosophy which seeks to offer a competitive pay mix of base salary, benefits, cash incentives and deferred compensation.

Salary is based on a number of factors, including external benchmarking data and market trends, State Street performance, SSGA performance, and individual overall performance. SSGA’s Global Human Resources department regularly participates in compensation surveys in order to provide SSGA with market-based compensation information that helps support individual pay decisions.

Additionally, subject to State Street and SSGA business results, State Street allocates an incentive pool to SSGA to reward its employees. The size of the incentive pool for most business units is based on the firm’s overall profitability and other factors, including performance against risk-related goals. For most SSGA investment teams, SSGA recognizes and rewards performance by linking annual incentive decisions for investment teams to the firm’s or business unit’s profitability and business unit investment performance over a multi-year period.

Incentive pool funding for most active investment teams is driven in part by the post-tax investment performance of fund(s) managed by the team versus the return levels of the benchmark index(es) of the fund(s) on a one-, three- and, in some cases, five-year basis. For most active investment teams, a material portion of incentive compensation for senior staff is deferred over a four-year period into the SSGA Long-Term Incentive (“SSGA LTI”) program. For these teams, The SSGA LTI program indexes the performance of these deferred awards against the post-tax investment performance of fund(s) managed by the team. This is intended to align our investment team’s compensation with client interests, both through annual incentive compensation awards and through the long-term value of deferred awards in the SSGA LTI program.

For the passive equity investment team, incentive pool funding is driven in part by the post-tax 1 and 3-year tracking error of the funds managed by the team against the benchmark indexes of the funds.

The discretionary allocation of the incentive pool to the business units within SSGA is influenced by market-based compensation data, as well as the overall performance of each business unit. Individual compensation decisions are made by the employee’s manager, in conjunction with the senior management of the employee’s business unit. These decisions are based on the overall performance of the employee and, as mentioned above, on the performance of the firm and business unit. Depending on the job level, a portion of the annual incentive may be awarded in deferred compensation, which may include cash and/or Deferred Stock Awards (State Street stock), which typically vest over a four-year period. This helps to retain staff and further aligns SSGA employees’ interests with SSGA clients’ and shareholders’ long-term interests.

Municipal Bond ETFs. The following table lists the number and types of other accounts managed by each of the key professionals primarily involved in the day-to-day portfolio management for each Municipal Bond ETF and assets under management in those accounts. The total number of accounts and assets have been allocated to each respective manager. Therefore, some accounts and assets have been counted twice.

[The portfolio managers listed above did not beneficially own any interests of any Fund as of June 30, 2021.]

[Compensation. Portfolio managers are compensated through a combination of base salary and variable components consisting of (i) a cash bonus; (ii) a long-term performance award; and (iii) participation in a profits interest plan.

Base salary. A portfolio manager’s base salary is determined based upon an analysis of the portfolio manager’s general performance, experience and market levels of base pay for such position.

Cash bonus. A portfolio manager is eligible to receive an annual cash bonus that is based on three variables: risk-adjusted investment performance relative to benchmark generally measured over the most recent one, three and five year periods (unless the portfolio manager’s tenure is shorter), ranking versus Morningstar peer funds generally measured over the most recent one, three and five year periods (unless the portfolio manager’s tenure is shorter), and management and peer reviews.

Long-term performance award. A portfolio manager is eligible to receive a long-term performance award that vests after three years. The amount of the award when granted is based on the same factors used in determining the cash bonus. The value of the award at the

completion of the three-year vesting period is adjusted based on the risk-adjusted investment performance of fund(s) managed by the portfolio manager during the vesting period and the performance of the TIAA organization as a whole.

Profits interest plan. Portfolio managers are eligible to receive profits interests in Nuveen Asset Management and its affiliate, Teachers Advisors, LLC, which vest over time and entitle their holders to a percentage of the firms’ annual profits. Profits interests are allocated to each portfolio manager based on such person’s overall contribution to the firms.

Material Conflicts of Interest. Actual or apparent conflicts of interest may arise when a portfolio manager has day-to-day management responsibilities with respect to more than one account. More specifically, portfolio managers who manage multiple accounts are presented a number of potential conflicts, including, among others, those discussed below.

The management of multiple accounts may result in a portfolio manager devoting unequal time and attention to the management of each account. Nuveen Asset Management seeks to manage such competing interests for the time and attention of portfolio managers by having portfolio managers focus on a particular investment discipline. Most accounts managed by a portfolio manager in a particular investment strategy are managed using the same investment models.

If a portfolio manager identifies a limited investment opportunity which may be suitable for more than one account, an account may not be able to take full advantage of that opportunity due to an allocation of filled purchase or sale orders across all eligible accounts. To deal with these situations, Nuveen Asset Management has adopted procedures for allocating limited opportunities across multiple accounts.

With respect to many of its clients’ accounts, Nuveen Asset Management determines which broker to use to execute transaction orders, consistent with its duty to seek best execution of the transaction. However, with respect to certain other accounts, Nuveen Asset Management may be limited by the client with respect to the selection of brokers or may be instructed to direct trades through a particular broker. In these cases, Nuveen Asset Management may place separate, non-simultaneous, transactions for a Fund and other accounts which may temporarily affect the market price of the security or the execution of the transaction, or both, to the detriment of the Fund or the other accounts.

Some clients are subject to different regulations. As a consequence of this difference in regulatory requirements, some clients may not be permitted to engage in all the investment techniques or transactions or to engage in these transactions to the same extent as the other accounts managed by the portfolio manager. Finally, the appearance of a conflict of interest may arise where Nuveen Asset Management has an incentive, such as a performance-based management fee, which relates to the management of some accounts, with respect to which a portfolio manager has day-to-day management responsibilities.

Nuveen Asset Management has adopted certain compliance procedures which are designed to address these types of conflicts common among investment managers. However, there is no guarantee that such procedures will detect each and every situation in which a conflict arises.]

Administrator. SSGA FM serves as the administrator to each series of the Trust, pursuant to an Administration Agreement dated June 1, 2015 (the “SSGA Administration Agreement”). Pursuant to the SSGA Administration Agreement, SSGA FM is obligated to continuously provide business management services to the Trust and its series and will generally, subject to the general oversight of the Trustees and except as otherwise provided in the SSGA Administration Agreement, manage all of the business and affairs of the Trust.

State Street serves as the sub-administrator to each series of the Trust, pursuant to a Sub-Administration Agreement dated June 1, 2015 (the “Sub-Administration Agreement”). Under the Sub-Administration Agreement, State Street is obligated to provide certain sub-administrative services to the Trust and its series. State Street is a wholly owned subsidiary of State Street Corporation, a publicly held financial holding company, and is affiliated with the Adviser. State Street’s mailing address is State Street Financial Center, One Lincoln Street, Boston, Massachusetts 02111.

State Street also serves as Custodian for the Trust’s series pursuant to a custodian agreement (“Custodian Agreement”). As Custodian, State Street holds Fund assets, calculates the net asset value of the Shares and calculates net income and realized capital gains or losses. State Street and the Trust will comply with the self-custodian provisions of Rule 17f-2 under the 1940 Act.

State Street also serves as Transfer Agent for each series of the Trust pursuant to a transfer agency agreement (“Transfer Agency Agreement”).

Compensation. As compensation for its services provided under the SSGA Administration agreement, SSGA FM, shall receive fees for the services, calculated based on the average aggregate net assets of the Trust and SIS, which are accrued daily and paid monthly out of its management fee.

As compensation for its services under the Sub-Administration Agreement, Custodian Agreement and Transfer Agency Agreement, State Street shall receive a fee for the services, calculated based on the average aggregate net assets of the Trust and SIS, which are accrued daily and paid monthly by the Adviser from its management fee. For each series of the Trust and SIS, an annual minimum fee applies. In addition, State Street shall receive global safekeeping and transaction fees, which are calculated on a per-country basis, in-kind creation (purchase) and redemption transaction fees (as described below) and revenue on certain cash balances. State Street may be reimbursed for its out-of-pocket expenses. The Investment Advisory Agreement provides that the Adviser will pay certain operating expenses of the Trust, including the fees due to State Street under the Custodian Agreement and the Transfer Agency Agreement.

Additional Sub-Administration Services. Also under the Sub-Administration Agreement, State Street receives an annual per Fund fee for certain services required in the preparation (including certain quarterly portfolio of investments services) and filing of Form N-PORT and Form N-CEN with the SEC (“N-PORT Related Services”). Additionally, State Street receives an annual per Fund fee for services regarding certain liquidity analytics (“Liquidity Risk Measurement Services”) under the Sub-Administration Agreement. N-PORT Related Services and Liquidity Risk Measurement Services fees are paid by the Adviser from its management fee.

The Trust’s Board has approved each Fund’s participation in a securities lending program. Under the securities lending program, each Fund has retained State Street to serve as the securities lending agent.

For the fiscal year ended June 30, 2021, the income earned by each Fund as well as the fees and/or compensation paid by each Fund (in dollars) pursuant to the Master Amended and Restated Securities Lending Authorization Agreement among SPDR Series Trust, SPDR Index Shares Funds and SSGA Active Trust, each on behalf of its respective series, and State Street (the “Securities Lending Authorization Agreement”) were as follows:

For the fiscal year ended June 30, 2021, State Street, acting as agent of the Funds, provided the following services to the Funds in connection with the Funds’ securities lending activities: (i) locating borrowers among an approved list of prospective borrowers; (ii) causing the delivery of loaned securities from a Fund to borrowers; (iii) monitoring the value of loaned securities, the value of collateral received, and other lending parameters; (iv) seeking additional collateral, as necessary, from borrowers; (v) receiving and holding collateral from borrowers, and facilitating the investment and reinvestment of all or substantially all cash collateral in an investment vehicle designated by the Funds; (vi) returning collateral to borrowers; (vii) facilitating substitute dividend, interest, and other distribution payments to the Funds from borrowers; (viii) negotiating the terms of each loan of securities, including but not limited to the amount of any loan premium, and monitoring the terms of securities loan agreements with prospective borrowers for consistency with the requirements of the Funds’ Securities Lending Authorization Agreement; (ix) selecting securities, including amounts (percentages), to be loaned; (x) recordkeeping and accounting services; and (xi) arranging for return of loaned securities to the Funds in accordance with the terms of the Securities Lending Authorization Agreement.

State Street Global Advisors Funds Distributors, LLC is the principal underwriter and Distributor of Shares. Its principal address is One Iron Street, Boston, Massachusetts 02210. Investor information can be obtained by calling 1-866-787-2257. The Distributor has entered into a distribution agreement (“Distribution Agreement”) with the Trust pursuant to which it distributes Shares of each Fund. The Distribution Agreement will continue for two years from its effective date and is renewable annually thereafter. Shares will be continuously offered for sale by the Trust through the Distributor only in Creation Units, as described in the Prospectus and below under “Purchase and Redemption of Creation Units.” Shares in less than Creation Units are not distributed by the Distributor. The Distributor will deliver the Prospectus to persons purchasing Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and a member of the Financial Industry Regulatory Authority (“FINRA”). The Distributor has no role in determining the investment policies of the Trust or which securities are to be purchased or sold by the Trust. An affiliate of the Distributor may assist Authorized Participants (as defined below) in assembling shares to purchase Creation Units or upon redemption, for which it may receive commissions or other fees from such Authorized Participants. An affiliate of the Distributor also receives compensation from State Street for providing on-line creation and redemption functionality to Authorized Participants through its Fund Connect application.

The Adviser or Distributor, or an affiliate of the Adviser or Distributor, may directly or indirectly make cash payments to certain broker-dealers for participating in activities that are designed to make registered representatives and other professionals more knowledgeable about exchange traded products, including the SPDR funds, or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems.

In addition, as of the date of this SAI, the Adviser and/or Distributor had arrangements whereby they may make payments, other than for the educational programs and marketing activities described above, to Pershing LLC (“Pershing”), RBC Capital Markets, LLC (“RBC”), LPL Financial, LLC (“LPL”), and Morgan Stanley Wealth Management, LLC. These amounts, which may be significant, are paid by the Adviser and/or Distributor from their own resources and not from Fund assets. Pursuant to these arrangements, Pershing, RBC and LPL have agreed to offer certain SPDR funds to their customers and not to charge certain of their customers any commissions when those customers purchase or sell shares of certain SPDR funds. Payments to a broker-dealer or intermediary may create potential conflicts of interest between the broker dealer or intermediary and its clients.

In addition, the Adviser or Distributor, or an affiliate of the Adviser or Distributor, as well as an index provider that is not affiliated with the Adviser or Distributor, may also reimburse expenses or make payments from their own assets to other persons in consideration of services or other activities that they believe may benefit the SPDR business or facilitate investment in SPDR funds.

The Distribution Agreement provides that it may be terminated at any time, without the payment of any penalty, as to a Fund: (i) by vote of a majority of the Independent Trustees or (ii) by vote of a majority (as defined in the 1940 Act) of the outstanding voting securities of the Fund, on at least 60 days written notice to the Distributor. The Distribution Agreement is also terminable upon 60 days’ notice by the Distributor and will terminate automatically in the event of its assignment (as defined in the 1940 Act).

The continuation of the Distribution Agreement and any other related agreements is subject to annual approval of the Board, including by a majority of the Independent Trustees, as described above.

The allocation among the Trust’s series of fees and expenses payable under the Distribution Agreement will be made pro rata in accordance with the daily net assets of the respective series.

The Distributor may also enter into agreements with securities dealers (“Soliciting Dealers”) who will solicit purchases of Creation Unit aggregations of Shares. Such Soliciting Dealers may also be Participating Parties (as defined in the “Book Entry Only System” section below) and/or DTC Participants (as defined below).

Pursuant to the Distribution Agreement, the Trust has agreed to indemnify the Distributor, and may indemnify Soliciting Dealers and Authorized Participants (as described below) entering into agreements with the Distributor, for certain liabilities, including certain liabilities arising under the federal securities laws, unless such loss or liability results from willful misfeasance, bad faith or gross negligence in the performance of its duties or the reckless disregard of its obligations and duties under the Distribution Agreement or other agreement, as applicable.

An unaffiliated index provider may make payments from its own assets to other persons in consideration for services provided or other activities that may facilitate investment in SPDR funds.

All portfolio transactions are placed on behalf of the Funds by the Adviser. Purchases and sales of securities on a securities exchange are affected through brokers who charge a commission for their services. Ordinarily commissions are not charged on over the counter orders (e.g., fixed income securities) because the Funds pay a spread which is included in the cost of the security and represents the difference between the dealer’s quoted price at which it is willing to sell the security and the dealer’s quoted price at which it is willing to buy the security. When a Fund executes an over the counter order with an electronic communications network or an alternative trading system, a commission is charged by such electronic communications networks and alternative trading systems as they execute such orders on an agency basis. Securities may be purchased from underwriters at prices that include underwriting fees.

In placing a portfolio transaction, the Adviser seeks to achieve best execution. The Adviser’s duty to seek best execution requires the Adviser to take reasonable steps to obtain for the client as favorable an overall result as possible for Fund portfolio transactions under the circumstances, taking into account various factors that are relevant to the particular transaction.

The Adviser refers to and selects from the list of approved trading counterparties maintained by the Adviser’s Credit Risk Management team. In selecting a trading counterparty for a particular trade, the Adviser seeks to weigh relevant factors including, but not limited to the following:

In selecting a trading counterparty, the price of the transaction and costs related to the execution of the transaction typically merit a high relative importance, depending on the circumstances. The Adviser does not necessarily select a trading counterparty based upon price and costs but may take other relevant factors into account if it believes that these are important in taking reasonable steps to obtain the best possible result for a Fund under the circumstances. Consequently, the Adviser may cause a client to pay a trading counterparty more than another trading counterparty might have charged for the same transaction in recognition of the value and quality of the brokerage services provided. The following matters may influence the relative importance that the Adviser places upon the relevant factors:

(i) The nature and characteristics of the order or transaction. For example, size of order, market impact of order, limits, or other instructions relating to the order;

(ii) The characteristics of the financial instrument(s) or other assets which are the subject of that order. For example, whether the order pertains to an equity, fixed income, derivative or convertible instrument;

(iii) The characteristics of the execution venues to which that order can be directed, if relevant. For example, availability and capabilities of electronic trading systems;

(iv) Whether the transaction is a ‘delivery versus payment’ or ‘over the counter’ transaction. The creditworthiness of the trading counterparty, the amount of existing exposure to a trading counterparty and trading counterparty settlement capabilities may be given a higher relative importance in the case of ‘over the counter’ transactions; and/or

The process by which trading counterparties are selected to effect transactions is designed to exclude consideration of the sales efforts conducted by broker-dealers in relation to the Funds.

The Adviser does not currently use the Funds’ assets in connection with third party soft dollar arrangements. While the Adviser does not currently use “soft” or commission dollars paid by the Funds for the purchase of third party research, the Adviser reserves the right to do so in the future.

Nuveen. Nuveen Asset Management is responsible for decisions to buy and sell securities for certain Funds, the negotiation of the prices to be paid or received for principal trades, and the allocation of its transactions among various dealer firms. Portfolio securities will normally be purchased directly from an underwriter in a new issue offering or in the over-the-counter secondary market from the principal dealers in such securities, unless it appears that a better price or execution may be obtained elsewhere. Portfolio securities will not be purchased from Nuveen Asset Management or its affiliates except in compliance with the 1940 Act.

Nuveen Asset Management expects that substantially all portfolio transactions will be effected on a principal (as opposed to an agency) basis and, accordingly, do not expect to pay significant amounts of brokerage commissions. Brokerage will not be allocated based on the sale of a Fund’s shares. Purchases from underwriters will include a commission or concession paid by the issuer to the underwriter, and purchases from dealers will include the spread between the bid and asked price. It is the policy of Nuveen Asset Management to seek the best execution under the circumstances of each trade. Nuveen Asset Management evaluates price as the primary consideration, with the financial condition, reputation and responsiveness of the dealer considered secondarily in determining best execution. Given the best execution obtainable, it may be Nuveen Asset Management’s practice to select dealers that, in addition, furnish research information (primarily credit analyses of issuers and general economic reports) and statistical and other services to Nuveen Asset Management. It is not possible to place a dollar value on information and statistical and other services received from dealers. Since it is only supplementary to Nuveen Asset Management’s own research efforts, the receipt of research information is not expected to reduce significantly Nuveen Asset Management’s expenses. For certain secondary market transactions where the execution capability of two brokers is judged to be of substantially similar quality, Nuveen Asset Management may randomly select one of them. Nuveen Asset Management may manage other investment companies and investment accounts for other clients that have investment objectives similar to certain Funds. Subject to applicable laws and regulations, Nuveen Asset Management seeks to allocate portfolio transactions equitably whenever concurrent decisions are made to purchase or sell securities by a Fund and another advisory account. In making such allocations the main factors to be considered will be the respective investment objectives, the relative size of the portfolio holdings of the same or comparable securities, the availability of cash for investment or need to raise cash, and the size of investment commitments generally held. While this procedure could have a detrimental effect on the price or amount of the securities (or, in the case of dispositions, the demand for securities) available to a Fund from time to time, Nuveen Asset Management believes that the benefits available will outweigh any disadvantage that may arise from exposure to simultaneous transactions.

The table below shows the aggregate dollar amount of brokerage commissions paid by the [Equity ETFs and the SPDR Bloomberg Barclays Convertible Securities ETF, SPDR Bloomberg Barclays High Yield Bond ETF and SPDR Portfolio Mortgage Backed Bond ETF for the past three fiscal years ended June 30. None of the brokerage commissions paid were paid to affiliated brokers and the Fixed Income ETFs (except the SPDR Bloomberg Barclays Convertible Securities ETF, SPDR Bloomberg Barclays High Yield Bond ETF and SPDR Portfolio Mortgage Backed Bond ETF) did not pay any brokerage commissions.] Brokerage commissions paid by a Fund may be substantially different from year to year for multiple reasons, including market volatility, the demand for a particular Fund, or increases or decreases in trading volume.

Securities of “Regular Broker-Dealers.” The Trust is required to identify any securities of its “regular brokers and dealers” (as such term is defined in the 1940 Act) which it may hold at the close of its most recent fiscal year. “Regular brokers or dealers” of the Trust are the ten brokers or dealers that, during the most recent fiscal year: (i) received the greatest dollar amounts of brokerage commissions from the Trust’s portfolio transactions; (ii) engaged as principal in the largest dollar amounts of portfolio transactions of the Trust; or (iii) sold the largest dollar amounts of the Trust’s shares.

The Trust’s holdings in Securities of Regular Broker-Dealers as of June 30, 2021.

Portfolio Turnover. Portfolio turnover may vary from year to year, as well as within a year. The Funds may experience higher portfolio turnover when migrating to a different benchmark index. High turnover rates are likely to result in comparatively greater brokerage expenses or transaction costs. The overall reasonableness of brokerage commissions and transaction costs is evaluated by the Adviser based upon its knowledge of available information as to the general level of commissions and transaction costs paid by other institutional investors for comparable services.

The following information supplements and should be read in conjunction with the section in the Prospectus entitled “ADDITIONAL PURCHASE AND SALE INFORMATION.”

The Depository Trust Company (“DTC”) acts as securities depositary for the Shares. Shares of each Fund are represented by securities registered in the name of DTC or its nominee, Cede & Co., and deposited with, or on behalf of, DTC. Except in the limited circumstance provided below, certificates will not be issued for Shares.

DTC, a limited-purpose trust company, was created to hold securities of its participants (the “DTC Participants”) and to facilitate the clearance and settlement of securities transactions among the DTC Participants in such securities through electronic book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC. More specifically, DTC is owned by a number of its DTC Participants and by the New York Stock Exchange (“NYSE”) and FINRA. Access to the DTC system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (the “Indirect Participants”).

Beneficial ownership of Shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in Shares (owners of such beneficial interests are referred to herein as “Beneficial Owners”) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase of Shares.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the Shares of each Fund held by each DTC Participant. The Trust, either directly or through a third party service, shall inquire of each such DTC Participant as to the number of Beneficial Owners holding Shares, directly or indirectly, through such DTC Participant. The Trust, either directly or through a third party service, shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant and/or third party service a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all Shares. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in Shares of a Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of Shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

The Trust has no responsibility or liability for any aspects of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such Shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants.

DTC may determine to discontinue providing its service with respect to Shares at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action either to find a replacement for DTC to perform its functions at a comparable cost or, if such a replacement is unavailable, to issue and deliver printed certificates representing ownership of Shares, unless the Trust makes other arrangements with respect thereto satisfactory to the Exchange.

Although the Funds do not have information concerning their beneficial ownership held in the names of DTC Participants, as of [October 2, 2021], the names, addresses and percentage ownership of each DTC Participant that owned of record 5% or more of the outstanding Shares of the Funds were as follows:

An Authorized Participant (as defined below) may hold of record more than 25% of the outstanding Shares of a Fund. From time to time, Authorized Participants may be a beneficial and/or legal owner of a Fund, may be affiliated with an index provider, may be deemed to have control of the applicable Fund and/or may be able to affect the outcome of matters presented for a vote of the shareholders of the Fund. Authorized Participants may execute an irrevocable proxy granting the Distributor or another affiliate of State Street (the “Agent”) power to vote or abstain from voting such Authorized Participant’s beneficially or legally owned Shares of a Fund. In such cases, the Agent shall mirror vote (or abstain from voting) such Shares in the same proportion as all other beneficial owners of the Fund.

As of [October 2, 2021], to the knowledge of the Trust, the following persons held of record or beneficially through one or more accounts 25% or more of the outstanding shares of the Funds.

[The Trustees and Officers of the Trust, as a group, own less than 1% of the Trust’s voting securities as of the date of this SAI.]

Each Fund issues and redeems its Shares on a continuous basis, at net asset value, only in a large specified number of Shares called a “Creation Unit.” The value of each Fund is determined once each business day, except with respect to the SPDR Bloomberg Barclays 1-3 Month T-Bill ETF, the value of which is determined twice each business day, as described under “Determination of Net Asset Value.” The Creation Unit size for a Fund may change. Authorized Participants (as defined below) will be notified of such change.

The principal consideration for creations and redemptions for each Equity ETF is in-kind, although this may be revised at any time without notice. The principal consideration for creations and redemptions for each Fixed Income ETF is set forth in the table below:

PURCHASE (CREATION). The Trust issues and sells Shares of each Fund only: in Creation Units on a continuous basis through the Principal Underwriter, without a sales load (but subject to transaction fees), at their NAV per share next determined after receipt of an order, on any Business Day (as defined below), in proper form pursuant to the terms of the Authorized Participant Agreement (“Participant Agreement”). A “Business Day” with respect to a Fund is, generally, any day on which the NYSE is open for business, although Fixed Income ETFs will also not be open for orders on Veterans Day and Columbus Day.

FUND DEPOSIT. The consideration for purchase of a Creation Unit of a Fund generally consists of either (i) the Deposit Securities and the Cash Component (defined below), computed as described below or (ii) the cash value of the Deposit Securities and the “Cash Component,” computed as described below. When accepting purchases of Creation Units for cash, a Fund may incur additional costs associated with the acquisition of Deposit Securities that would otherwise be provided by an in-kind purchaser.

Together, the Deposit Securities or Deposit Cash, as applicable, and the Cash Component constitute the “Fund Deposit,” which represents the minimum initial and subsequent investment amount for a Creation Unit of a Fund. The “Cash Component,” which may include a Dividend Equivalent Payment, is an amount equal to the difference between the net asset value of the Shares (per Creation Unit) and the market value of the Deposit Securities or Deposit Cash, as applicable. The “Dividend Equivalent Payment” enables a Fund to make a complete distribution of dividends on the day preceding the next dividend payment date, and is an amount equal, on a per Creation Unit basis, to the dividends on all the portfolio securities of the Fund (“Dividend Securities”) with ex-dividend dates within the accumulation period for such distribution (the “Accumulation Period”), net of expenses and liabilities for such period, as if all of the Dividend Securities had been held by the Fund for the entire Accumulation Period. The Accumulation Period begins on the ex-dividend date for each Fund and ends on the day preceding the next ex-dividend date. If the Cash Component is a positive number (i.e., the net asset value per Creation Unit exceeds the market value of the Deposit Securities or Deposit Cash, as applicable), the Cash Component shall be such positive amount. If the Cash Component is a negative number (i.e., the net asset value per Creation Unit is less than the market value of the Deposit Securities or Deposit Cash, as applicable), the Cash Component shall be such negative amount and the creator will be entitled to receive cash in an amount equal to the Cash Component. The Cash Component serves the function of compensating for any differences between the net asset value per Creation Unit and the market value of the Deposit Securities or Deposit Cash, as applicable. Computation of the Cash Component excludes any stamp duty or other similar fees and expenses payable upon transfer of beneficial ownership of the Deposit Securities, if applicable, which shall be the sole responsibility of the Authorized Participant (as defined below).

The Custodian, through NSCC, makes available on each Business Day, prior to the opening of business on the Exchange (currently 9:30 a.m., Eastern time), the list of the names and the required number of shares of each Deposit Security or the required amount of Deposit Cash, as applicable, to be included in the current standard Fund Deposit (based on information at the end of the previous Business Day) for a Fund. Such standard Fund Deposit is subject to any applicable adjustments as described below, in order to effect purchases of Creation Units of a Fund until such time as the next-announced composition of the Deposit Securities or the required amount of Deposit Cash, as applicable, is made available.

The identity and number of shares of the Deposit Securities or the amount of Deposit Cash, as applicable, required for a Fund Deposit for each Fund may be changed from time to time with a view to the investment objective of the Fund. Information regarding the Fund Deposit necessary for the purchase of a Creation Unit is made available to Authorized Participants and other market participants seeking to transact in Creation Unit aggregations.

The Trust intends to require the substitution of an amount of cash (i.e., a “cash in lieu” amount) to replace any Deposit Security that is a TBA transaction. The amount of cash contributed will be equivalent to the price of the TBA transaction listed as a Deposit Security. As noted above, the Trust reserves the right to permit or require the substitution of Deposit Cash to replace any Deposit Security, which shall be added to the Cash Component, including, without limitation, in situations where the Deposit Security: (i) may not be available in sufficient quantity for delivery, (ii) may not be eligible for transfer through the systems of DTC for corporate securities and municipal securities or the Federal Reserve System for U.S. Treasury securities; (iii) may not be eligible for trading by an Authorized Participant (as defined below) or the investor for which it is acting; (iv) would be restricted under the securities laws or where the delivery of the Deposit Security to the Authorized Participant would result in the disposition of the Deposit Security by the Authorized Participant becoming restricted under the securities laws, or (v) in certain other situations (collectively, “non-standard orders”). The Trust also reserves the right to: (i) permit or require the substitution of Deposit Securities in lieu of Deposit Cash; and (ii) include or remove Deposit Securities from the basket in anticipation of portfolio changes. The adjustments described above will reflect changes, known to the Adviser on the date of announcement to be in effect by the time of delivery of the Fund Deposit, in the composition of the subject Index being tracked by the relevant Fund or resulting from certain corporate actions.

PROCEDURES FOR PURCHASE OF CREATION UNITS. To be eligible to place orders with the Principal Underwriter, as facilitated via the Transfer Agent, to purchase a Creation Unit of a Fund, an entity must be (i) a “Participating Party”, i.e., a broker-dealer or other participant in the clearing process through the Continuous Net Settlement System of the NSCC (the “Clearing Process”), a clearing agency that is registered with the SEC; or (ii) a DTC Participant (see “Book Entry Only System”), and, with respect to the Fixed Income ETFs, must have the ability to clear through the Federal Reserve System. In addition, each Participating Party or DTC Participant (each, an “Authorized Participant”) must execute a Participant Agreement that has been agreed to by the Principal Underwriter and the Transfer Agent, and that has been accepted by the Trust, with respect to purchases and redemptions of Creation Units. Each Authorized Participant will agree, pursuant to the terms of a Participant Agreement, on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that it will pay to the Trust, an amount of cash sufficient to pay the Cash Component together with the creation transaction fee (described below) and any other applicable fees, taxes and additional variable charge.

All orders to purchase Shares directly from a Fund, including non-standard orders, must be placed for one or more Creation Units and in the manner and by the time set forth in the Participant Agreement and/or the applicable order form. The date on which an order to purchase Creation Units (or an order to redeem Creation Units, as set forth below) is received and accepted is referred to as the “Order Placement Date.”

An Authorized Participant may require an investor to make certain representations or enter into agreements with respect to the order (e.g., to provide for payments of cash, when required). Investors should be aware that their particular broker may not have executed a Participant Agreement and that, therefore, orders to purchase Shares directly from a Fund in Creation Units have to be placed by the investor’s broker through an Authorized Participant that has executed a Participant Agreement. In such cases there may be additional charges to such investor. At any given time, there may be only a limited number of broker-dealers that have executed a Participant Agreement and only a small number of such Authorized Participants may have international capabilities.

On days when the Exchange or the bond markets close earlier than normal, a Fund may require orders to create Creation Units to be placed earlier in the day. In addition, if a market or markets on which a Fund’s investments are primarily traded is closed, the Fund will also generally not accept orders on such day(s). Orders must be transmitted by an Authorized Participant by telephone or other transmission method acceptable to the Distributor pursuant to procedures set forth in the Participant Agreement and in accordance with the applicable order form. Those placing orders through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order by the cut-off time. Economic or market disruptions or changes, or telephone or other communication failure may impede the ability to reach the Distributor or an Authorized Participant.

Fund Deposits must be delivered by an Authorized Participant through the Federal Reserve System (for cash and U.S. government securities), or through DTC (for corporate securities and municipal securities), through a subcustody agent (for foreign securities) and/or through such other arrangements allowed by the Trust or its agents. With respect to foreign Deposit Securities, the Custodian shall cause the subcustodian of a Fund to maintain an account into which the Authorized Participant shall deliver, on behalf of itself or the party on whose behalf it is acting, such Deposit Securities. Foreign Deposit Securities must be delivered to an account maintained at the applicable local subcustodian. The Fund Deposit transfer must be ordered by the Authorized Participant in a timely fashion so as to ensure the delivery of the requisite number of Deposit Securities or Deposit Cash, as applicable, to the account of a Fund or its agents by no later than the Settlement Date. The “Settlement Date” for a Fund is generally the second Business Day (“T+2”) after the Order Placement Date. The Settlement Date for the SPDR Global Dow ETF is the third Business Day (“T+3”) after the Order Placement Date. The Settlement Date for the SPDR Portfolio TIPS ETF is the first Business Day (“T+1”) after the Order Placement Date. The Settlement Date for the SPDR Bloomberg Barclays 1-3 Month T-Bill ETF is the same day (“T+0”) as the Order Placement Date for orders placed prior to 12:00 p.m. Eastern time; orders placed after 12:00 p.m. Eastern time will have a Settlement Date of the first Business Day (“T+1”) following the Order Placement Date. All questions as to the number of Deposit Securities or Deposit Cash to be delivered, as applicable, and the validity, form and eligibility (including time of receipt) for the deposit of any tendered securities or cash, as applicable, will be determined by the Trust, whose determination shall be final and binding. The amount of cash represented by the Cash Component must be transferred directly to the Custodian through the Federal Reserve Bank wire transfer system in a timely manner so as to be received by the Custodian no later than the Settlement Date. If the Cash Component and the Deposit Securities or Deposit Cash, as applicable, are not received in a timely manner by the Settlement Date, the creation order may be cancelled. Upon written notice to the Distributor, such canceled order may be resubmitted the following Business Day using a Fund Deposit as newly constituted to reflect the then current NAV of the Fund. The delivery of Creation Units so created generally will occur no later than the second Business Day following the day on which the purchase order is deemed received by the Distributor. Delivery of Creation Units will occur no later than the third Business Day following the day on which the purchase order is deemed received by the Distributor for the SPDR Global Dow ETF. Delivery of Creation Units for the SPDR Portfolio TIPS ETF will occur no later than the first Business Day following the day on which the purchase order is deemed received by the Distributor. Delivery of Creation Units for the SPDR Bloomberg Barclays 1-3 Month T-Bill ETF will occur on the same day for orders placed before 12:00 p.m. Eastern time, and the following Business Day for order placed after 12:00 p.m. Eastern time.

The order shall be deemed to be received on the Business Day on which the order is placed provided that the order is placed in proper form prior to the applicable cut-off time and the federal funds in the appropriate amount are deposited by 2:00 p.m. or 3:00 p.m. Eastern time (per applicable instructions), with the Custodian on the Settlement Date. If the order is not placed in proper form as required, or federal funds in the appropriate amount are not received by 2:00 p.m. or 3:00 p.m. Eastern time (per applicable instructions) on the Settlement Date, then the order may be deemed to be rejected and the Authorized Participant shall be liable to the Fund for losses, if any, resulting therefrom. A creation request is considered to be in “proper form” if all procedures set forth in the Participant Agreement, order form and this SAI are properly followed.

ISSUANCE OF A CREATION UNIT. Except as provided herein, Creation Units will not be issued until the transfer of good title to the Trust of the Deposit Securities or payment of Deposit Cash, as applicable, and the payment of the Cash Component have been completed. When the subcustodian has confirmed to the Custodian that the required Deposit Securities (or the cash value thereof) have been delivered to the account of the relevant subcustodian or subcustodians, the Principal Underwriter and the Adviser shall be notified of such delivery, and the Trust will issue and cause the delivery of the Creation Units.

In instances where the Trust accepts Deposit Securities for the purchase of a Creation Unit, the Creation Unit may be purchased in advance of receipt by the Trust of all or a portion of the applicable Deposit Securities as described below. In these circumstances, the initial deposit will have a value greater than the net asset value of the Shares on the date the order is placed in proper form since in addition to available Deposit Securities, cash must be deposited in an amount equal to the sum of (i) the Cash Component, plus (ii) an additional amount of cash equal to a percentage of the market value as set forth in the Participant Agreement, of the undelivered Deposit Securities (the “Additional Cash Deposit”), which shall be maintained in a general non-interest bearing collateral account. An additional amount of cash shall be required to be deposited with the Trust, pending delivery of the missing Deposit Securities to the extent necessary to maintain the Additional Cash Deposit with the Trust in an amount at least equal to the applicable percentage, as set forth in the Participant Agreement, of the daily marked to market value of the missing Deposit Securities. The Trust may use such Additional Cash Deposit to buy the missing Deposit Securities at any time. Authorized Participants will be liable to the Trust for all costs, expenses, dividends, income and taxes associated with missing Deposit Securities, including the costs incurred by the Trust in connection with any such purchases. These costs will be deemed to include the amount by which the actual purchase price of the Deposit Securities exceeds the market value of such Deposit Securities on the day the purchase order was deemed received by the Principal Underwriter plus the brokerage and related transaction costs associated with such purchases. The Trust will return any unused portion of the Additional Cash Deposit once all of the missing Deposit Securities have been properly received by the Custodian or purchased by the Trust and deposited into the Trust. In addition, a transaction fee as set forth below under “Creation Transaction Fees” will be charged in all cases and an additional variable charge may also be applied. The delivery of Creation Units so created generally will occur no later than the Settlement Date.

ACCEPTANCE OF ORDERS OF CREATION UNITS. The Trust reserves the absolute right to reject an order for Creation Units transmitted in respect of a Fund at its discretion, including, without limitation, if (a) the order is not in proper form; (b) the Deposit Securities or Deposit Cash, as applicable, delivered by the Authorized Participant are not as disseminated through the facilities of the NSCC for that date by the Custodian; (c) the investor(s), upon obtaining the Shares ordered, would own 80% or more of the currently outstanding Shares of the Fund; (d) acceptance of the Deposit Securities would have certain adverse tax consequences to the Fund; (e) the acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (f) the acceptance of the Fund Deposit would otherwise, in the discretion of the Trust or the Adviser, have an adverse effect on the Trust or the rights of beneficial owners; (g) the acceptance or receipt of the order for a Creation Unit would, in the opinion of counsel to the Trust, be unlawful; or (h) in the event that circumstances outside the control of the Trust, the Custodian, the Transfer Agent and/or the Adviser make it for all practical purposes not feasible to process orders for Creation Units. Examples of such circumstances include acts of God or public service or utility problems such as fires, floods, extreme weather conditions and power outages resulting in telephone, telecopy and computer failures; market conditions or activities causing trading halts; systems failures involving computer or other information systems affecting the Trust, the Principal Underwriter, the Custodian, the Transfer Agent, DTC, NSCC, Federal Reserve System, or any other participant in the creation process, and other extraordinary events. The Trust or its agents shall communicate to the Authorized Participant its rejection of an order. The Trust, the Transfer Agent, the Custodian and the Principal Underwriter are under no duty, however, to give notification of any defects or irregularities in the delivery of Fund Deposits nor shall either of them incur any liability for the failure to give any such notification. The Trust, the Transfer Agent, the Custodian and the Principal Underwriter shall not be liable for the rejection of any purchase order for Creation Units.

All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by the Trust, and the Trust’s determination shall be final and binding.

REDEMPTION. Shares may be redeemed only in Creation Units at their net asset value next determined after receipt of a redemption request in proper form by a Fund through the Transfer Agent and only on a Business Day. EXCEPT UPON LIQUIDATION OF A FUND, THE TRUST WILL NOT REDEEM SHARES IN AMOUNTS LESS THAN CREATION UNITS. Investors must accumulate enough Shares in the secondary market to constitute a Creation Unit in order to have such Shares redeemed by the Trust. There can be no assurance, however, that there will be sufficient liquidity in the public trading market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of Shares to constitute a redeemable Creation Unit.

With respect to each Fund, the Custodian, through the NSCC, makes available prior to the opening of business on the Exchange (currently 9:30 a.m. Eastern time) on each Business Day, the list of the names and share quantities of securities designated by the Fund that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Redemption Securities”). Redemption Securities received on redemption may not be identical to Deposit Securities. The identity and number of shares of the Redemption Securities or the Cash Redemption Amount (defined below) may be changed from time to time with a view to the investment objective of a Fund.

Redemption proceeds for a Creation Unit are paid either in-kind or in cash or a combination thereof, as determined by the Trust. With respect to in-kind redemptions of a Fund, redemption proceeds for a Creation Unit will consist of Redemption Securities plus cash in an amount equal to the difference between the net asset value of the Shares being redeemed, as next determined after a receipt of a request in proper form, and the value of the Redemption Securities (the “Cash Redemption Amount”), less a fixed redemption transaction fee and any applicable additional variable charge as set forth below. In the event that the Redemption Securities have a value greater than the net asset value of the Shares, a compensating cash payment equal to the differential is required to be made by or through an Authorized Participant by the redeeming shareholder. Notwithstanding the foregoing: (i) the Trust will substitute a cash in lieu amount to replace any Fund Security that is a TBA transaction and the amount of cash paid out in such cases will be equivalent to the value of the TBA transaction listed as a Fund Security and (ii) at the Trust’s discretion, an Authorized Participant may receive the corresponding cash value of the securities in lieu of the in-kind securities value representing one or more Redemption Securities.

PROCEDURES FOR REDEMPTION OF CREATION UNITS. After the Trust has deemed an order for redemption received, the Trust will initiate procedures to transfer the requisite Redemption Securities and the Cash Redemption Amount to the Authorized Participant by the Settlement Date. With respect to in-kind redemptions of a Fund, the calculation of the value of the Redemption Securities and the Cash Redemption Amount to be delivered upon redemption will be made by the Custodian according to the procedures set forth under “Determination of Net Asset Value”, computed on the Business Day on which a redemption order is deemed received by the Trust. Therefore, if a redemption order in proper form is submitted to the Principal Underwriter by a DTC Participant by the specified time on the Order Placement Date, and the requisite number of Shares of a Fund are delivered to the Custodian prior to 2:00 p.m. or 3:00 p.m. Eastern time (per applicable instructions) on the Settlement Date, then the value of the Redemption Securities and the Cash Redemption Amount to be delivered will be determined by the Custodian on such Order Placement Date. If the requisite number of Shares of the Fund are not delivered by 2:00 p.m. or 3:00 p.m. Eastern time (per applicable instructions) on the Settlement Date, the Fund will not release the underlying securities for delivery unless collateral is posted in such percentage amount of missing Shares as set forth in the Participant Agreement (marked to market daily).

With respect to in-kind redemptions of a Fund, in connection with taking delivery of shares of Redemption Securities upon redemption of Creation Units, an Authorized Participant must maintain appropriate custody arrangements with a qualified broker-dealer, bank or other custody providers in each jurisdiction in which any of the Redemption Securities are customarily traded (or such other arrangements as allowed by the Trust or its agents), to which account such Redemption Securities will be delivered. Deliveries of redemption proceeds generally will be made within two Business Days, or in the case of the SPDR Global Dow ETF within three Business Days, of the trade date. Due to the schedule of holidays in certain countries, however, the delivery of in-kind redemption proceeds may take longer than two or three Business Days, as applicable, after the day on which the redemption request is received in proper form. If the Authorized Participant has not made appropriate arrangements to take delivery of the Redemption Securities in the applicable foreign jurisdiction and it is not possible to make other such arrangements, or if it is not possible to effect deliveries of the Redemption Securities in such jurisdiction, the Trust may, in its discretion, exercise its option to redeem such Shares in cash, and the Authorized Participant will be required to receive its redemption proceeds in cash.

If it is not possible to make other such arrangements, or if it is not possible to effect deliveries of the Redemption Securities, the Trust may in its discretion exercise its option to redeem such Shares in cash, and the redeeming investor will be required to receive its redemption proceeds in cash. In addition, an investor may request a redemption in cash that a Fund may, in its sole discretion, permit. In either case, the investor will receive a cash payment equal to the NAV of its Shares based on the NAV of Shares of the relevant Fund next determined after the redemption request is received in proper form (minus a redemption transaction fee and additional charge for requested cash redemptions specified above, to offset the Trust’s brokerage and other transaction costs associated with the disposition of Redemption Securities). A Fund may also, in its sole discretion, upon request of a shareholder, provide such redeemer a portfolio of securities that differs from the exact composition of the Redemption Securities but does not differ in net asset value.

An Authorized Participant submitting a redemption request is deemed to represent to the Trust that, as of the close of the Business Day on which the redemption request was submitted, it (or its client) will own (within the meaning of Rule 200 of Regulation SHO) or has arranged to borrow for delivery to the Trust on or prior to the Settlement Date of the redemption request, the requisite number of Shares of the relevant Fund to be redeemed as a Creation Unit. In either case, the Authorized Participant is deemed to acknowledge

that: (i) it (or its client) has full legal authority and legal right to tender for redemption the requisite number of Shares of the applicable Fund and to receive the entire proceeds of the redemption; and (ii) if such Shares submitted for redemption have been loaned or pledged to another party or are the subject of a repurchase agreement, securities lending agreement or any other arrangement affecting legal or beneficial ownership of such Shares being tendered, there are no restrictions precluding the tender and delivery of such Shares (including borrowed shares, if any) for redemption, free and clear of liens, on the redemption Settlement Date. The Trust reserves the right to verify these representations at its discretion, but will typically require verification with respect to a redemption request from a Fund in connection with higher levels of redemption activity and/or short interest in the Fund. If the Authorized Participant, upon receipt of a verification request, does not provide sufficient verification of its representations as determined by the Trust, the redemption request will not be considered to have been received in proper form and may be rejected by the Trust.

Redemptions of Shares for Redemption Securities will be subject to compliance with applicable federal and state securities laws and each Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that the Trust could not lawfully deliver specific Redemption Securities upon redemptions or could not do so without first registering the Redemption Securities under such laws. An Authorized Participant or an investor for which it is acting subject to a legal restriction with respect to a particular security included in the Redemption Securities applicable to the redemption of Creation Units may be paid an equivalent amount of cash. The Authorized Participant may request the redeeming investor of the Shares to complete an order form or to enter into agreements with respect to such matters as compensating cash payment. Further, an Authorized Participant that is not a “qualified institutional buyer,” (“QIB”) as such term is defined under Rule 144A of the Securities Act, will not be able to receive Redemption Securities that are restricted securities eligible for resale under Rule 144A. An Authorized Participant may be required by the Trust to provide a written confirmation with respect to QIB status in order to receive Redemption Securities.

The right of redemption may be suspended or the date of payment postponed with respect to a Fund (1) for any period during which the Exchange is closed (other than customary weekend and holiday closings); (2) for any period during which trading on the Exchange is suspended or restricted; (3) for any period during which an emergency exists as a result of which disposal of the Shares of the Fund or determination of the NAV of the Shares is not reasonably practicable; or (4) in such other circumstance as is permitted by the SEC.

REQUIRED EARLY ACCEPTANCE OF ORDERS FOR CERTAIN INTERNATIONAL FUNDS. Notwithstanding the foregoing, as described in the Participant Agreement and/or the applicable order form, certain Funds may require orders to be placed prior to the trade date, as described in the Participant Agreement or the applicable order form, in order to receive the trade date’s net asset value. The cut-off time to receive the trade date’s net asset value will not precede the calculation of the net asset value of a Fund’s shares on the prior Business Day. Orders to purchase Shares of such Funds that are submitted on the Business Day immediately preceding a holiday or a day (other than a weekend) that the equity markets in the relevant foreign market are closed may not be accepted. Authorized Participants may be notified that the cut-off time for an order may be earlier on a particular Business Day, as described in the Participant Agreement and the applicable order form.

CREATION AND REDEMPTION TRANSACTION FEES. A transaction fee, as set forth in the table below, is imposed for the transfer and other transaction costs associated with the purchase or redemption of Creation Units, as applicable. Authorized Participants will be required to pay a fixed creation transaction fee and/or a fixed redemption transaction fee, as applicable, on a given day regardless of the number of Creation Units created or redeemed on that day. A Fund may adjust the transaction fee from time to time. An additional charge or a variable charge (discussed below) will be applied to certain creation and redemption transactions, including non-standard orders and whole or partial cash purchases or redemptions. With respect to creation orders, Authorized Participants are responsible for the costs of transferring the securities constituting the Deposit Securities to the account of the Trust and with respect to redemption orders, Authorized Participants are responsible for the costs of transferring the Redemption Securities from the Trust to their account or on their order. Investors who use the services of a broker or other such intermediary may also be charged a fee for such services.

The following information supplements and should be read in conjunction with the sections in the applicable Prospectus entitled “PURCHASE AND SALE INFORMATION” and “ADDITIONAL PURCHASE AND SALE INFORMATION.”

NAV per Share for each Fund is computed by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of Shares outstanding. Expenses and fees, including the management fees, are accrued daily and taken into account for purposes of determining NAV. The NAV of each Fund other than the SPDR Bloomberg Barclays 1-3 Month T-Bill ETF is calculated by State Street and determined once daily as of the close of the regular trading session on the NYSE (ordinarily 4:00 p.m. Eastern time) on each day that such exchange is open. With respect to the SPDR Bloomberg Barclays 1-3 Month T-Bill ETF, the Fund’s NAV is calculated and determined twice daily on each day the NYSE is open at the following times: (i) 12:00 p.m. Eastern time; and (ii) at the close of the regular trading session on the NYSE. Creation/redemption order cut-off times may be earlier on any day that the Securities Industry and Financial Markets Association (or applicable exchange or market on which a Fund’s investments are traded) announces an early closing time. Any assets or liabilities denominated in currencies other than the U.S. dollar are converted into U.S. dollars at market rates on the date of valuation (generally as of 4:00 p.m. London time) as quoted by one or more sources.

In calculating a Fund’s NAV per Share, the Fund’s investments are generally valued using market valuations. A market valuation generally means a valuation (i) obtained from an exchange, a pricing service, or a major market maker (or dealer), (ii) based on a price quotation or other equivalent indication of value supplied by an exchange, a pricing service, or a major market maker (or dealer) or (iii) based on amortized cost. A Fund relies on a third-party service provider for assistance with the daily calculation of the Fund’s NAV. The third-party service provider, in turn, relies on other parties for certain pricing data and other inputs used in the calculation of the Fund’s NAV. Therefore, a Fund is subject to certain operational risks associated with reliance on its service provider and that service provider’s sources of pricing and other data. NAV calculation may be adversely affected by operational risks arising from factors such as errors or failures in systems and technology. Such errors or failures may result in an inaccurately calculated NAV, delays in the calculation of a NAV and/or the inability to calculate a NAV over extended time periods. A Fund may be unable to recover any losses associated with such failures. In the case of shares of other funds that are not traded on an exchange, a market valuation means such fund’s published NAV per share. A price obtained from a pricing service based on such pricing service’s valuation matrix may be considered a market valuation. The Adviser may use various pricing services, or discontinue the use of any

pricing service, as approved by the Board from time to time. Fixed-income assets are generally valued as of the announced closing time for trading in fixed-income instruments in a particular market or exchange, and generally 4:00 p.m. EST for U.S. fixed-income assets (except U.S. fixed-income assets are generally valued as of 12:00 p.m. EST for the SPDR Bloomberg Barclays 1-3 Month T-Bill ETF’s 12:00 p.m. Eastern time NAV calculation). Fixed-income assets are generally valued at the mean of the bid and ask prices for bank loans and inflation protected securities, and at the bid price for all other fixed-income assets.

In the event that current market valuations are not readily available or are deemed unreliable, the Trust’s procedures require the Oversight Committee to determine a security’s fair value if a market price is not readily available. In determining such value the Oversight Committee may consider, among other things, (i) price comparisons among multiple sources, (ii) a review of corporate actions and news events, and (iii) a review of relevant financial indicators (e.g., movement in interest rates, market indices, and prices from each Fund’s Index Provider). In these cases, the Fund’s NAV may reflect certain portfolio securities’ fair values rather than their market prices. The fair value of a portfolio instrument is generally the price which a Fund might reasonably expect to receive upon its current sale in an orderly market between market participants. Ascertaining fair value requires a determination of the amount that an arm’s-length buyer, under the circumstances, would currently pay for the portfolio instrument. Fair value pricing involves subjective judgments and it is possible that the fair value determination for a security is materially different than the value that could be realized upon the sale of the security. In addition, fair value pricing could result in a difference between the prices used to calculate a Fund’s NAV and the prices used by the Fund’s benchmark Index. This may result in a difference between the Fund’s performance and the performance of the applicable Fund’s benchmark Index. With respect to securities that are primarily listed on foreign exchanges, the value of a Fund’s portfolio securities may change on days when you will not be able to purchase or sell your Shares.

The following information supplements and should be read in conjunction with the section in each Prospectus entitled “DISTRIBUTIONS.”

Dividends from net investment income, if any, are generally declared and paid monthly by each Fixed Income ETF and quarterly for each Equity ETF (except SPDR MSCI USA StrategicFactors^SM ETF and SPDR ICE Preferred Securities ETF), but may vary significantly from period to period. Income dividend distributions, if any, for the SPDR MSCI USA StrategicFactors^SM ETF and SPDR ICE Preferred Securities ETF are generally distributed to shareholders semi-annually and monthly, respectively, but may vary significantly from period to period. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for a Fund to improve index tracking or to comply with the distribution requirements of the Internal Revenue Code, in all events in a manner consistent with the provisions of the 1940 Act.

Dividends and other distributions on Shares are distributed, as described below, on a pro rata basis to Beneficial Owners of such Shares. Dividend payments are made through DTC Participants and Indirect Participants to Beneficial Owners then of record with proceeds received from the Trust.

Management of the Trust reserves the right to declare special dividends if, in its reasonable discretion, such action is necessary or advisable to preserve a Fund’s eligibility for treatment as a RIC under the Internal Revenue Code or to avoid imposition of income or excise taxes at the Fund level.

Broker dealers, at their own discretion, may offer a dividend reinvestment service under which Shares are purchased in the secondary market at current market prices. Investors should consult their broker dealer for further information regarding any dividend reinvestment service offered by such broker dealer.

The following is a summary of certain federal income tax considerations generally affecting the Funds and their shareholders that supplements the discussions in the Prospectuses. No attempt is made to present a comprehensive explanation of the federal, state, local or foreign tax treatment of the Funds or their shareholders, and the discussion here and in each Prospectus is not intended to be a substitute for careful tax planning.

The following general discussion of certain federal income tax consequences is based on the Internal Revenue Code and the regulations issued thereunder as in effect on the date of this SAI. New legislation, as well as administrative changes or court decisions, may significantly change the conclusions expressed herein, and may have a retroactive effect with respect to the transactions contemplated herein.

The following information should be read in conjunction with the section in the Prospectuses entitled “ADDITIONAL TAX INFORMATION.”

TAXATION OF THE FUNDS. Each Fund is treated as a separate corporation for federal income tax purposes. A Fund therefore is considered to be a separate entity in determining its treatment under the rules for RICs described herein and in the Prospectuses. Losses in one series of the Trust do not offset gains in any other series of the Trust and the requirements (other than certain organizational requirements) for qualifying for treatment as a RIC are determined at the Fund level rather than at the Trust level. Each Fund has elected or will elect and intends to qualify each year to be treated as a separate RIC under Subchapter M of the Internal Revenue Code. As such, each Fund should not be subject to federal income tax on its net investment income and capital gains, if any, to the extent that it timely distributes such income and capital gains to its shareholders. In order to qualify for treatment as a RIC, a Fund must distribute annually to its shareholders at least the sum of 90% of its taxable net investment income (generally including the excess of net short-term capital gains over net long-term capital losses) and 90% of its net tax-exempt interest income, if any (the “Distribution Requirement”) and also must meet several additional requirements. Among these requirements are the following: (i) at least 90% of a Fund’s gross income each taxable year must be derived from dividends, interest, payments with respect to certain securities loans, gains from the sale or other disposition of stock, securities or foreign currencies, or other income derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly traded partnerships (the “Qualifying Income Requirement”); and (ii) at the end of each quarter of a Fund’s taxable year, its assets must be diversified so that (a) at least 50% of the market value of its total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited, in respect to any one issuer, to an amount not greater in value than 5% of the value of the Fund’s total assets and to not more than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of its total assets is invested in the securities (other than U.S. government securities or securities of other RICs) of any one issuer, the securities (other than securities of other RICs) of two or more issuers that it controls and that are engaged in the same, similar, or related trades or businesses, or the securities of one or more qualified publicly traded partnerships (the “Diversification Requirement”).

If a Fund fails to satisfy the Qualifying Income Requirement or the Diversification Requirement in any taxable year, the Fund may be eligible for relief provisions if the failures are due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the Diversification Requirement where the Fund corrects the failure within a specified period of time. In order to be eligible for the relief provisions with respect to a failure to meet the Diversification Requirement, a Fund may be required to dispose of certain assets. If these relief provisions were not available to a Fund and it were to fail to qualify for treatment as a RIC for a taxable year, all of its taxable income would be subject to tax at the regular corporate rate without any deduction for distributions to shareholders, and its distributions (including capital gains distributions) generally would be taxable as ordinary income dividends to its shareholders, subject to the dividends-received deduction for corporate shareholders and the lower tax rates on qualified dividend income received by noncorporate shareholders. To requalify for treatment as a RIC in a subsequent taxable year, the Fund would be required to satisfy the RIC qualification requirements for that year and to distribute any earnings and profits from any year in which the Fund failed to qualify for tax treatment as a RIC. If a Fund failed to qualify as a RIC for a period greater than two taxable years, it would generally be required to pay a Fund-level tax on certain net built-in gains recognized with respect to certain of its assets upon a disposition of such assets within five years of qualifying as a RIC in a subsequent year. The Board reserves the right not to maintain the qualification of a Fund for treatment as a RIC if it determines such course of action to be beneficial to shareholders.

As discussed more fully below, each Fund intends to distribute substantially all of its net investment income and its capital gains for each taxable year.

If a Fund meets the Distribution Requirement but retains some or all of its income or gains, it will be subject to federal income tax to the extent any such income or gains are not distributed. A Fund may designate certain amounts retained as undistributed net capital gain in a notice to its shareholders, who (i) will be required to include in income for U.S. federal income tax purposes, as long-term capital gain, their proportionate shares of the undistributed amount so designated, (ii) will be entitled to credit their proportionate shares of the income tax paid by the Fund on that undistributed amount against their federal income tax liabilities and to claim refunds to the extent such credits exceed their liabilities and (iii) will be entitled to increase their tax basis, for federal income tax purposes, in their Shares by an amount equal to the excess of the amount of undistributed net capital gain included in their respective income over their respective income tax credits. If a Fund failed to satisfy the Distribution Requirement for any taxable year, it would be taxed as a regular corporation, with consequences generally similar to those described in the preceding paragraph.

Given the concentration of certain of the Indexes in a relatively small number of securities, it may not be possible for certain Funds to fully implement sampling methodologies while satisfying the Diversification Requirement. A Fund’s efforts to satisfy the Diversification Requirement may affect the Fund’s execution of its investment strategy and may cause the Fund’s return to deviate from that of the applicable Index, and the Fund’s efforts to track the applicable Index may cause it inadvertently to fail to satisfy the Diversification Requirement.

A Fund will be subject to a 4% excise tax on certain undistributed income if it does not distribute to its shareholders in each calendar year an amount at least equal to 98% of its ordinary income for the calendar year plus 98.2% of its capital gain net income for the twelve months ended October 31 of such year, subject to an increase for any shortfall in the prior year’s distribution. Each Fund intends to declare and distribute dividends and distributions in the amounts and at the times necessary to avoid the application of this 4% excise tax.

A Fund may elect to treat part or all of any “qualified late year loss” as if it had been incurred in the succeeding taxable year in determining the Fund’s taxable income, net capital gain, net short-term capital gain, and earnings and profits. The effect of this election is to treat any such “qualified late year loss” as if it had been incurred in the succeeding taxable year in characterizing Fund distributions for any calendar year. A “qualified late year loss” generally includes net capital loss, net long-term capital loss, or net short-term capital loss incurred after October 31 of the current taxable year (commonly referred to as “post-October losses”) and certain other late-year losses.

Capital losses in excess of capital gains (“net capital losses”) are not permitted to be deducted against a RIC’s net investment income. Instead, for U.S. federal income tax purposes, potentially subject to certain limitations, a Fund may carry a net capital loss from any taxable year forward indefinitely to offset its capital gains, if any, in years following the year of the loss. To the extent subsequent capital gains are offset by such losses, they will not result in U.S. federal income tax liability to the Fund and may not be distributed as capital gains to its shareholders. Generally, the Funds may not carry forward any losses other than net capital losses.

TAXATION OF SHAREHOLDERS—DISTRIBUTIONS. Each Fund intends to distribute annually to its shareholders substantially all of its investment company taxable income (computed without regard to the deduction for dividends paid), its net tax-exempt income, if any, and any net capital gain (net recognized long-term capital gains in excess of net recognized short-term capital losses, taking into account any capital loss carryforwards). Each Fund will report to shareholders annually the amounts of dividends paid from ordinary income, the amount of distributions of net capital gain, the portion of dividends which may qualify for the dividends-received deduction, the portion of dividends which may qualify for treatment as qualified dividend income, and the amount of exempt-interest dividends, if any.

Subject to certain limitations, dividends reported by a Fund as qualified dividend income will be taxable to noncorporate shareholders at rates of up to 20%. Dividends may be reported by a Fund as qualified dividend income if they are attributable to qualified dividend income received by the Fund. Qualified dividend income includes, in general, subject to certain holding period requirements and other requirements, dividend income from certain U.S. and foreign corporations. Subject to certain limitations, eligible foreign corporations include those incorporated in possessions of the United States, those incorporated in certain countries with comprehensive tax treaties with the United States and other foreign corporations if the stock with respect to which the dividends are paid is tradable on an established securities market in the United States. A dividend generally will not be treated as qualified dividend income to the extent that (i) the shareholder has not held the stock on which the dividend was paid for more than 60 days during the 121-day period that begins on the date that is 60 days before the date on which the stock becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, for more than 90 days during the 181-day period beginning 90 days before such date, (ii) the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property, or (iii) the shareholder elects to treat such dividend as investment income under section 163(d)(4)(B) of the Internal Revenue Code. The holding period requirements described in this paragraph apply to shareholders’ investments in the Funds and to the Funds’ investments in underlying dividend-paying stocks. Dividends treated as received by a Fund from a REIT or another RIC may be treated as qualified dividend income generally only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or RIC. It is expected that dividends received by a Fund from a REIT and distributed from that Fund to a shareholder generally will be taxable to the shareholder as ordinary income. Additionally, income derived in connection with a Fund’s securities lending activities, will, in general, not be treated as qualified dividend income. If 95% or more of a Fund’s gross income (calculated without taking into account net capital gain derived from sales or other dispositions of stock or securities) consists of qualified dividend income, that Fund may report all distributions of such income as qualified dividend income.

Certain dividends received by a Fund from U.S. corporations (generally, dividends received by a Fund in respect of any share of stock (1) with a tax holding period of at least 46 days during the 91-day period beginning on the date that is 45 days before the date on which the stock becomes ex-dividend as to that dividend and (2) that is held in an unleveraged position) when distributed and appropriately so reported by the Fund may be eligible for the 50% dividends-received deduction generally available to corporations under the Internal Revenue Code. Dividends received by a Fund from REITs will not be eligible for that deduction. In order to qualify for the deduction, corporate shareholders must meet the minimum holding period requirement stated above with respect to their Shares, taking into account any holding period reductions from certain hedging or other transactions or positions that diminish their risk of loss with respect to their Shares, and, if they borrow to acquire or otherwise incur debt attributable to Shares, they may be denied a portion of the dividends-received deduction with respect to those Shares. Any corporate shareholder should consult its tax adviser regarding the possibility that its tax basis in its Shares may be reduced, for U.S. federal income tax purposes, by reason of “extraordinary dividends” received with respect to the Shares and, to the extent such basis would be reduced below zero, current recognition of income may be required.

Distributions from a Fund’s net short-term capital gains will generally be taxable to shareholders as ordinary income. Distributions from a Fund’s net capital gain will be taxable to shareholders at long-term capital gains rates, regardless of how long shareholders have held their Shares. Long-term capital gains are generally taxed to noncorporate shareholders at rates of up to 20%. Certain capital gain dividends attributable to dividends a Fund receives from REITs may be taxable to noncorporate shareholders at a rate of 25%.

The Municipal Bond ETFs intend to satisfy certain conditions (including requirements as to the proportion of their assets invested in municipal securities) that will enable them to report distributions from the interest income generated by their investments in municipal securities as exempt-interest dividends. Shareholders receiving exempt-interest dividends will not be subject to regular federal income tax on the amount of such dividends, but (as discussed below) exempt-interest dividends may be taken into account in determining shareholders’ liability under the federal alternative minimum tax. Insurance proceeds received by the Fund under any insurance policies in respect of scheduled interest payments on defaulted municipal securities will generally be correspondingly excludable from federal gross income. In the case of non-appropriation by a political subdivision, however, there can be no assurance that payments made by the insurer representing interest on non-appropriation lease obligations will be excludable from gross income for federal income tax purposes.

Exempt-interest dividends paid by the Municipal Bond ETFs and attributable to interest earned on municipal securities issued by a state or its political subdivisions are generally exempt in the hands of a shareholder from income tax imposed by that state, but exempt-interest dividends attributable to interest on municipal securities issued by another state generally will not be exempt from such income tax.

Distributions by the Municipal Bond ETFs of net interest received from certain taxable temporary investments (such as certificates of deposit, commercial paper and obligations of the U.S. Government, its agencies and instrumentalities) and net short-term capital gains realized by a Municipal Bond ETF, if any, will be taxable to shareholders as ordinary income. If a Municipal Bond ETF purchases a municipal security at a market discount, any gain realized by the Municipal Bond ETF upon sale or redemption of the municipal security will be treated as taxable interest income to the extent of the market discount, and any gain realized in excess of the market discount will be treated as capital gains.

If you lend your Shares in a Municipal Bond ETF pursuant to a securities lending or similar arrangement, you may lose the ability to treat dividends paid by the Municipal Bond ETF while the Shares are held by the borrower as tax-exempt income. Interest on indebtedness incurred by a shareholder to purchase or carry Shares of the Municipal Bond ETFs will not be deductible for U.S. federal income tax purposes. If a shareholder receives exempt-interest dividends with respect to any share of a Municipal Bond ETF and if the share is held by the shareholder for six months or less, then any loss on the sale or exchange of the share may, to the extent of the exempt-interest dividends, be disallowed. In addition, the Internal Revenue Code may require a shareholder in a Municipal Bond ETF that receives exempt-interest dividends to treat as taxable income a portion of certain otherwise non-taxable social security and railroad retirement benefit payments. Furthermore, a portion of any exempt-interest dividend paid by a Municipal Bond ETF that represents income derived from certain revenue or private activity bonds held by a Municipal Bond ETF may not retain its tax-exempt status in the hands of a shareholder who is a “substantial user” of a facility financed by such bonds, or a “related person” thereof. Shareholders should consult their own tax advisers as to whether they are “substantial users” with respect to a facility or “related” to such users within the meaning of the Internal Revenue Code.

Federal tax law imposes an alternative minimum tax with respect to individuals. Interest on certain municipal securities that meet the definition of private activity bonds under the Internal Revenue Code is included as an item of tax preference in determining the amount of a taxpayer’s alternative minimum taxable income. To the extent that a Municipal Bond ETF receives income from private activity bonds, a portion of the dividends paid by it, although otherwise exempt from federal income tax, will be taxable to those shareholders subject to the alternative minimum tax regime. The Municipal Bond ETFs will annually supply shareholders with a report indicating the percentage of their income attributable to municipal securities required to be included in calculating the federal alternative minimum tax.

Although dividends generally will be treated as distributed when paid, any dividend declared by a Fund in October, November or December and payable to shareholders of record in such a month that is paid during the following January will be treated for U.S. federal income tax purposes as received by shareholders on December 31 of the calendar year in which it was declared.

If a Fund’s distributions exceed its earnings and profits, all or a portion of the distributions made in the taxable year may be treated as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when the Shares on which the distribution was received are sold. After a shareholder’s basis in the Shares has been reduced to zero, distributions in excess of earnings and profits will be treated as gain from the sale of the shareholder’s Shares.

Distributions that are reinvested in additional Shares of a Fund through the means of a dividend reinvestment service, if offered by your broker-dealer, will nevertheless be taxable dividends to the same extent as if such dividends had been received in cash.

A 3.8% Medicare contribution tax generally applies to all or a portion of the net investment income of a shareholder who is an individual and not a nonresident alien for federal income tax purposes and who has adjusted gross income (subject to certain adjustments) that exceeds a threshold amount ($250,000 if married filing jointly or if considered a “surviving spouse” for federal income tax purposes, $125,000 if married filing separately, and $200,000 in other cases). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts. For these purposes, interest, dividends and certain capital gains (generally including capital gain distributions and capital gains realized on the sale of Shares) are generally taken into account in computing a shareholder’s net investment income[, but exempt-interest dividends generally are not taken into account].

Distributions of ordinary income and capital gains may also be subject to foreign, state and local taxes depending on a shareholder’s circumstances.

TAXATION OF SHAREHOLDERS—SALE OF SHARES. In general, a sale of Shares results in capital gain or loss, and for individual shareholders, is taxable at a federal rate dependent upon the length of time the Shares were held. A sale of Shares held for a period of one year or less at the time of such sale will, for tax purposes, generally result in short-term capital gains or losses, and a sale of those held for more than one year will generally result in long-term capital gains or losses. Long-term capital gains are generally taxed to noncorporate shareholders at rates of up to 20%.

Gain or loss on the sale of Shares is measured by the difference between the amount received and the adjusted tax basis of the Shares. Shareholders should keep records of investments made (including Shares acquired through reinvestment of dividends and distributions) so they can compute the tax basis of their Shares. It may not be advantageous from a tax perspective for shareholders to sell or redeem Shares of a Municipal Bond ETF after tax-exempt income has accrued but before the record date for the exempt-interest dividend representing the distribution of such income. Because such accrued tax-exempt income is included in the net asset value per share, such a sale or redemption could result in treatment of the portion of the sales or redemption proceeds equal to the accrued tax-exempt interest as taxable gain (to the extent the sale or redemption price exceeds the shareholder’s tax basis in the Municipal Bond ETF Shares disposed of) rather than tax-exempt interest.

A loss realized on a sale of Shares may be disallowed if substantially identical Shares are acquired (whether through the reinvestment of dividends or otherwise) within a sixty-one (61) day period beginning thirty (30) days before and ending thirty (30) days after the date that the Shares are disposed of. In such a case, the basis of the Shares acquired must be adjusted to reflect the disallowed loss. Any loss upon the sale of Shares held for six (6) months or less will be disallowed to the extent of exempt-interest dividends paid on such Shares, and any amount of the loss that exceeds the amount disallowed will be treated as long-term capital loss to the extent of any amounts treated as distributions to the shareholder of long-term capital gain (including any amounts credited to the shareholder as undistributed capital gains).

COST BASIS REPORTING. The cost basis of Shares acquired by purchase will generally be based on the amount paid for the Shares and then may be subsequently adjusted for other applicable transactions as required by the Internal Revenue Code. The difference between the selling price and the cost basis of Shares generally determines the amount of the capital gain or loss realized on the sale or exchange of Shares. Contact the broker through whom you purchased your Shares to obtain information with respect to the available cost basis reporting methods and elections for your account.

TAXATION OF FUND INVESTMENTS. Dividends and interest received by a Fund on foreign securities may give rise to withholding and other taxes imposed by foreign countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If a Fund meets certain requirements, which include a requirement that more than 50% of the value of the Fund’s total assets at the close of its respective taxable year consist of certain foreign securities (generally including foreign government securities), then the Fund should be eligible to file an election with the IRS that may enable its shareholders, in effect, to receive either the benefit of a foreign tax credit, or a tax deduction, with respect to certain foreign and U.S. possessions income taxes paid by the Fund, subject to certain limitations. [If at least 50% of a Fund’s total assets at the close of each quarter of a taxable year consists of interests in other RICs (including money market funds and ETFs that are taxable as RICs), the Fund may make the same election and pass through to its shareholders their pro rata shares of qualified foreign taxes paid by those other RICs and passed through to the Fund for that taxable year.] Pursuant to this election, a Fund would treat the applicable foreign taxes as dividends paid to its shareholders. Each such shareholder would be required to include a proportionate share of those taxes in gross income as income received from a foreign source and must treat the amount so included as if the shareholder had paid the foreign tax directly. The shareholder may then either deduct the taxes deemed paid by him or her in computing his or her taxable income or, alternatively, use the foregoing information in calculating any foreign tax credit the shareholder may be entitled to use against such shareholder’s federal income tax. If a Fund makes this election, the Fund will report annually to its shareholders the respective amounts per share of the Fund’s income from sources within, and taxes paid to, foreign countries and U.S. possessions. No deduction for such taxes will be permitted to individuals in computing their alternative minimum tax liability. If a Fund does not make this election, the Fund will be entitled to claim a deduction for certain foreign taxes incurred by the Fund. In certain instances, the Fund might not elect to apply otherwise allowable U.S. federal income tax deductions for those foreign taxes, whether or not credits or deductions for those foreign taxes could be passed through to its shareholders pursuant to the election described above. If the Fund does not elect to apply these deductions, taxable distributions you receive from the Fund may be larger than they would have been if the Fund had taken deductions for such taxes. Under certain circumstances, if a Fund receives a refund of foreign taxes paid in respect of a prior year, the value of Shares could be affected or any foreign tax credits or deductions passed through to shareholders in respect of the Fund’s foreign taxes for the current year could be reduced.

Certain of the Funds’ investments may be subject to complex provisions of the Internal Revenue Code (including provisions relating to hedging transactions, straddles, integrated transactions, foreign currency contracts, forward foreign currency contracts, and notional principal contracts) that, among other things, may affect the character of gains and losses realized by a Fund (e.g., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also may require a Fund to mark-to-market certain types of positions in its portfolio (i.e., treat them as if they were closed out) which may cause the Fund to recognize income without receiving cash with which to make distributions to its shareholders in amounts necessary to satisfy the RIC distribution requirements for avoiding income and excise taxes. The Funds intend to monitor their transactions, intend to make appropriate tax elections, and intend to make appropriate entries in their books and records in order to mitigate the effect of these rules and preserve the Funds’ qualification for treatment as RICs.

[Certain investments made by a Fund may be treated as equity in passive foreign investment companies or “PFICs” for federal income tax purposes. In general, a passive foreign investment company is a foreign corporation (i) that receives at least 75% of its annual gross income from passive sources (such as interest, dividends, certain rents and royalties, or capital gains) or (ii) where at least 50% of its assets (computed based on average fair market value) either produce or are held for the production of passive income. If a Fund acquires any equity interest (under Treasury regulations that may be promulgated in the future, generally including not only stock but also an option to acquire stock such as is inherent in a convertible bond) in a PFIC, the Fund could be subject to U.S. federal income tax and nondeductible interest charges on “excess distributions” received from such companies or on gain from the sale of stock in such companies, even if all income or gain actually received by the Fund is timely distributed to its shareholders. The Fund would not be able to pass through to its shareholders any credit or deduction for such a tax. A “qualified electing fund” election or a “mark to market” election may be available that would ameliorate these adverse tax consequences, but such elections could require the applicable Fund to recognize taxable income or gain (subject to the distribution requirements applicable to RICs, as described above) without the concurrent receipt of cash. In order to satisfy the distribution requirements and avoid a tax at the Fund level, a Fund may be required to liquidate portfolio securities that it might otherwise have continued to hold, potentially resulting in additional taxable gain or loss to the Fund. Gains from the sale of stock of PFICs may also be treated as ordinary income. In order for a Fund to make a qualified electing fund election with respect to a PFIC, the PFIC would have to agree to provide certain tax information to the Fund on an annual basis, which it might not agree to do. The Funds may limit and/or manage their holdings in PFICs to limit their tax liability or maximize their returns from these investments.

If a sufficient portion of the interests in a foreign issuer are held or deemed held by a Fund, independently or together with certain other U.S. persons, that issuer may be treated as a “controlled foreign corporation” (a “CFC”) with respect to the Fund, in which case the Fund will be required to take into account each year, as ordinary income, its share of certain portions of that issuer’s income, whether or not such amounts are distributed. A Fund may have to dispose of its portfolio securities (potentially resulting in the recognition of taxable gain or loss, and potentially under disadvantageous circumstances) to generate cash, or may have to borrow the cash, to meet its distribution requirements and avoid Fund-level taxes. In addition, some Fund gains on the disposition of interests in such an issuer may be treated as ordinary income. A Fund may limit and/or manage its holdings in issuers that could be treated as CFCs in order to limit its tax liability or maximize its after-tax return from these investments.]

Each Fund is required for federal income tax purposes to mark-to-market and recognize as income for each taxable year its net unrealized gains and losses on certain futures contracts as of the end of the year as well as those actually realized during the year. Gain or loss from futures and options contracts on broad-based indexes required to be marked to market will be 60% long-term and 40% short-term capital gain or loss. Application of this rule may alter the timing and character of distributions to shareholders. A Fund may be required to defer the recognition of losses on futures contracts, options contracts and swaps to the extent of any unrecognized gains on offsetting positions held by the Fund. It is anticipated that certain net gain realized from the closing out of futures or options contracts will be considered gain from the sale of securities and therefore will be qualifying income for purposes of the Qualifying Income Requirement.

Investments by a Fund in zero coupon or other discount securities will result in income to the Fund equal to a portion of the excess face value of the securities over their issue price (the “original issue discount” or “OID”) each year that the securities are held, even though the Fund may receive no cash interest payments or may receive cash interest payments that are less than the income recognized for tax purposes. In other circumstances, whether pursuant to the terms of a security or as a result of other factors outside the control of the Fund, a Fund may recognize income without receiving a commensurate amount of cash. Such income is included in determining the amount of income that a Fund must distribute to maintain its eligibility for treatment as a RIC and to avoid the payment of federal income tax, including the nondeductible 4% excise tax described above.

Any market discount recognized on a market discount bond is taxable as ordinary income. A market discount bond is a bond acquired in the secondary market at a price below redemption value, or below adjusted issue price if issued with original issue discount. Absent an election by a Fund to include the market discount in income as it accrues, gain on the Fund’s disposition of such an obligation will be treated as ordinary income rather than capital gain to the extent of the accrued market discount. If a Municipal Bond ETF purchases a municipal security at a market discount, any gain realized by such Fund upon sale or redemption of the municipal security will be treated as taxable interest income to the extent of the market discount, and any gain realized in excess of the market discount will be treated as capital gains. Where the income required to be recognized as a result of the OID and/or market discount rules is not matched by a corresponding cash receipt by a Fund, the Fund may be required to borrow money or dispose of securities to enable the Fund to make distributions to its shareholders in order to qualify for treatment as a RIC and eliminate taxes at the Fund level.

Special rules apply if a Fund holds inflation-indexed bonds, such as Treasury Inflation-Protected Securities (TIPS). Generally, all stated interest on inflation-indexed bonds is taken into income by a Fund under its regular method of accounting for interest income. The amount of any positive inflation adjustment for a taxable year, which results from an increase in the inflation-adjusted principal amount of the bond, is treated as OID. The amount of a Fund’s OID in a taxable year with respect to a bond will increase a Fund’s taxable income for such year without a corresponding receipt of cash, until the bond matures. As a result, the Fund may need to use other sources of cash to satisfy its distribution requirements for the applicable year. The amount of any negative inflation adjustments, which result from a decrease in the inflation-adjusted principal amount of the bond, first reduces the amount of interest (including stated interest, OID, and market discount, if any) otherwise includable in the Fund’s taxable income with respect to the bond for the taxable year; any remaining negative adjustments will be either treated as ordinary loss or, in certain circumstances, carried forward to reduce the amount of interest income taken into account with respect to the bond in future taxable years.

[For tax years beginning after December 31, 2017 and before January 1, 2026, a noncorporate taxpayer is generally eligible for a deduction of up to 20% of the taxpayer’s “qualified REIT dividends.” If a Fund receives dividends (other than capital gain dividends) in respect of REIT shares, the Fund may report its own dividends as eligible for the 20% deduction, to the extent the Fund’s income is derived from such qualified REIT dividends, as reduced by allocable Fund expenses. In order for a Fund’s dividends to be eligible for this deduction when received by a noncorporate shareholder, the Fund must meet certain holding period requirements with respect to the REIT shares on which the Fund received the eligible dividends, and the noncorporate shareholder must meet certain holding period requirements with respect to the Shares.]

TAX-EXEMPT SHAREHOLDERS. Certain tax-exempt shareholders, including qualified pension plans, individual retirement accounts, salary deferral arrangements, 401(k) plans, and other tax-exempt entities, generally are exempt from federal income taxation except with respect to their unrelated business taxable income (“UBTI”). Under current law, a Fund generally serves to block UBTI from being realized by its tax-exempt shareholders. However, notwithstanding the foregoing, tax-exempt shareholders could realize UBTI by virtue of their investment in a Fund where, for example, (i) the Fund invests in REITs that hold residual interests in real estate mortgage investment conduits (“REMICs”) or (ii) Shares constitute debt-financed property in the hands of the tax-exempt shareholders within the meaning of section 514(b) of the Internal Revenue Code. Charitable remainder trusts are subject to special rules and should consult their tax advisors. [There are no restrictions preventing a Fund from holding investments in REITs that hold residual interests in REMICs, and a Fund may do so.] The IRS has issued guidance with respect to these issues and prospective shareholders, especially charitable remainder trusts, are strongly encouraged to consult with their tax advisors regarding these issues.

Certain tax-exempt educational institutions will be subject to a 1.4% tax on net investment income. For these purposes, certain dividends and capital gain distributions, and certain gains from the disposition of Shares (among other categories of income), are generally taken into account in computing a shareholder’s net investment income.

FOREIGN SHAREHOLDERS. Dividends, other than capital gains dividends and exempt-interest dividends, “short-term capital gain dividends” and “interest-related dividends” (described below), paid by a Fund to shareholders who are nonresident aliens or foreign entities will be subject to a 30% United States withholding tax unless a reduced rate of withholding or a withholding exemption is provided under applicable treaty law to the extent derived from investment income and short-term capital gain or unless such income is effectively connected with a U.S. trade or business carried on through a permanent establishment in the United States. Nonresident shareholders are urged to consult their own tax advisors concerning the applicability of the United States withholding tax and the proper withholding form(s) to be submitted to a Fund. A non-U.S. shareholder who fails to provide an appropriate IRS Form W-8 may be subject to backup withholding at the appropriate rate.

Dividends reported by a Fund as (i) interest-related dividends, to the extent such dividends are derived from the Fund’s “qualified net interest income,” or (ii) short-term capital gain dividends, to the extent such dividends are derived from the Fund’s “qualified short-term gain,” are generally exempt from this 30% withholding tax. “Qualified net interest income” is a Fund’s net income derived from U.S.-source interest and original issue discount, subject to certain exceptions and limitations. “Qualified short-term gain” generally means the excess of a Fund’s net short-term capital gain for the taxable year over its net long-term capital loss, if any. In the case of Shares held through an intermediary, the intermediary may withhold even if the Fund reports the payment as an interest-related dividend or as a short-term capital gain dividend. Non-U.S. shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

Unless certain non-U.S. entities that hold Shares comply with IRS requirements that will generally require them to report information regarding U.S. persons investing in, or holding accounts with, such entities, a 30% withholding tax may apply to Fund distributions (other than exempt-interest dividends) payable to such entities. A non-U.S. shareholder may be exempt from the withholding described in this paragraph under an applicable intergovernmental agreement between the U.S. and a foreign government, provided that the shareholder and the applicable foreign government comply with the terms of such agreement.

Non-U.S. persons are subject to U.S. tax on disposition of a “United States real property interest” (a “USRPI”). Gain on such a disposition is sometimes referred to as “FIRPTA gain.” The Internal Revenue Code provides a look-through rule for distributions of “FIRPTA gain” if certain requirements are met. If the look-through rule applies, certain distributions attributable to income treated as received by a Fund from REITs may be treated as gain from the disposition of a USRPI, causing distributions to be subject to U.S. withholding tax at rates of up to 21%, and requiring non-U.S. investors to file nonresident U.S. income tax returns. Also, FIRPTA gain may be subject to a 30% branch profits tax in the hands of a non-U.S. shareholder that is treated as a corporation for federal income tax purposes. Under certain circumstances, Shares may qualify as USRPIs, which could result in 15% withholding on certain distributions and gross redemption proceeds paid to certain non-U.S. investors.

BACKUP WITHHOLDING. A Fund will be required in certain cases to withhold (as “backup withholding”) on amounts (including exempt-interest dividends) payable to any shareholder who (1) has provided the Fund either an incorrect tax identification number or no number at all, (2) is subject to backup withholding by the IRS for failure to properly report payments of interest or dividends, (3) has failed to certify to the Fund that such shareholder is not subject to backup withholding, or (4) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). The backup withholding rate is currently 24%. Backup withholding will not be applied to payments that have been subject to the 30% withholding tax on shareholders who are neither citizens nor permanent residents of the U.S.

CREATION UNITS. An Authorized Participant who exchanges securities for Creation Units generally will recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and the sum of the exchanger’s aggregate basis in the securities surrendered plus the amount of cash paid for such Creation Units. A person who redeems Creation Units will generally recognize a gain or loss equal to the difference between the exchanger’s basis in the Creation Units and the sum of the aggregate market value of any securities received plus the amount of any cash received for such Creation Units. The IRS, however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position.

Any gain or loss realized upon a creation of Creation Units will be treated as capital gain or loss if the Authorized Participant holds the securities exchanged therefor as capital assets, and otherwise will be ordinary income or loss. Similarly, any gain or loss realized upon a redemption of Creation Units will be treated as capital gain or loss if the Authorized Participant holds the Shares comprising the Creation Units as capital assets, and otherwise will be ordinary income or loss. Any capital gain or loss realized upon the creation of Creation Units will generally be treated as long-term capital gain or loss if the securities exchanged for such Creation Units have been held for more than one year, and otherwise will be short-term capital gain or loss. Any capital gain or loss realized upon the redemption of Creation Units will generally be treated as long-term capital gain or loss if the Shares comprising the Creation Units have been held for more than one year, and otherwise, will generally be short-term capital gain or loss. Any capital loss realized upon a redemption of Creation Units held for six (6) months or less will be disallowed to the extent of exempt-interest dividends paid with respect to the Creation Units, and to the extent not disallowed will be treated as a long-term capital loss to the extent of any amounts treated as distributions to the applicable Authorized Participant of long-term capital gains with respect to the Creation Units (including any amounts credited to the Authorized Participant as undistributed capital gains).

A Fund has the right to reject an order for Creation Units if the purchaser (or a group of purchasers) would, upon obtaining the Shares so ordered, own 80% or more of the outstanding shares of the Fund and if, pursuant to section 351 of the Internal Revenue Code, the Fund would have a basis in any deposit securities different from the market value of such securities on the date of deposit. A Fund also has the right to require information necessary to determine beneficial Share ownership for purposes of the 80% determination. If a Fund does issue Creation Units to a purchaser (or a group of purchasers) that would, upon obtaining the Shares so ordered, own 80% or more of the outstanding shares of the Fund, the purchaser (or a group of purchasers) may not recognize gain or loss upon the exchange of securities for Creation Units.

Persons purchasing or redeeming Creation Units should consult their own tax advisors with respect to the tax treatment of any creation or redemption transaction.

CERTAIN POTENTIAL TAX REPORTING REQUIREMENTS. Under promulgated Treasury regulations, if a shareholder recognizes a loss on disposition of a Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder (or certain greater amounts over a combination of years), the shareholder must file with the IRS a disclosure statement on IRS Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a RIC are not excepted. A shareholder who fails to make the required disclosure to the IRS may be subject to adverse tax consequences, including significant penalties. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisers to determine the applicability of these regulations in light of their individual circumstances.

The foregoing discussion is a summary only and is not intended as a substitute for careful tax planning. Purchasers of Shares should consult their own tax advisors as to the tax consequences of investing in such Shares, including under state, local and other tax laws. Finally, the foregoing discussion is based on applicable provisions of the Internal Revenue Code, regulations, judicial authority and administrative interpretations in effect on the date hereof. Changes in applicable authority could materially affect the conclusions discussed above, and such changes often occur.

STATE TAX MATTERS. The discussion of state and local tax treatment is based on the assumptions that the Funds will qualify for treatment under Subchapter M of the Internal Revenue Code as RICs, that they will satisfy the conditions which will cause distributions to qualify as exempt-interest dividends to shareholders when distributed as intended, and that each Fund will distribute all interest and dividends it receives to its shareholders. The tax discussion summarizes general state and local tax laws which are currently in effect and which are subject to change by legislative, judicial or administrative action; any such changes may be retroactive with respect to the applicable Fund’s transactions. Investors should consult a tax advisor for more detailed information about state and local taxes to which they may be subject.

Many states grant tax-free status to dividends paid to you from interest earned on direct obligations of the U.S. government, subject in some states to minimum investment requirements that must be met by the Fund. Investment in Government National Mortgage Association (“Ginnie Mae”) or Federal National Mortgage Association (“Fannie Mae”) securities, banker’s acceptances, commercial paper, and repurchase agreements collateralized by U.S. government securities do not generally qualify for such tax-free treatment. The rules on exclusion of this income are different for corporate shareholders.

Each Fund issues Shares of beneficial interest, par value $.01 per Share. The Board may designate additional funds.

Each Share issued by the Trust has a pro rata interest in the assets of the corresponding series of the Trust. Shares have no preemptive, exchange, subscription or conversion rights and are freely transferable. Each Share is entitled to participate equally in dividends and distributions declared by the Board with respect to each Fund, and in the net distributable assets of each Fund on liquidation.

Each Share has one vote with respect to matters upon which a shareholder vote is required consistent with the requirements of the 1940 Act and the rules promulgated thereunder. Shares of all series of the Trust (“Funds”) vote together as a single class except that if the matter being voted on affects only a particular fund it will be voted on only by that fund and if a matter affects a particular fund differently from other Funds, that fund will vote separately on such matter. Under Massachusetts law, the Trust is not required to hold an annual meeting of shareholders unless required to do so under the 1940 Act. The policy of the Trust is not to hold an annual meeting of shareholders unless required to do so under the 1940 Act. All Shares of the Trust (regardless of the fund) have noncumulative voting rights for the election of Trustees. Under Massachusetts law, Trustees of the Trust may be removed by vote of the shareholders.

Under Massachusetts law, shareholders of a business trust may, under certain circumstances, be held personally liable as partners for obligations of the Trust. However, the Declaration of Trust contains an express disclaimer of shareholder liability for acts or obligations of the Trust, requires that Trust obligations include such disclaimer, and provides for indemnification and reimbursement of expenses out of the Trust’s property for any shareholder held personally liable for the obligations of the Trust. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Trust itself would be unable to meet its obligations. Given the above limitations on shareholder personal liability, and the nature of each Fund’s assets and operations, the risk to shareholders of personal liability is believed to be remote.

Shareholder inquiries may be made by writing to the Trust, c/o the Distributor, State Street Global Advisors Funds Distributors, LLC at One Iron Street, Boston, Massachusetts 02210.

Morgan, Lewis & Bockius LLP, 1111 Pennsylvania Avenue NW, Washington, DC 20004, serves as counsel to the Trust. [ ], located at [ ], serves as the independent registered public accounting firm for the Trust. [ ] performs annual audits of the Funds’ financial statements and provides other audit, tax and related services.

The Trust generally intends to effect deliveries of portfolio securities on a basis of “T” plus two Business Days (i.e., days on which the NYSE is open), or in the case of the SPDR Global Dow ETF on a basis of “T” plus three Business Days, in the relevant foreign market of a Fund. The ability of the Trust to effect in-kind redemptions within two or three Business Days, as applicable, of receipt of a redemption request is subject, among other things, to the condition that, within the time period from the date of the request to the date of delivery of the securities, there are no days that are local market holidays on the relevant Business Days. For every occurrence of one or more intervening holidays in the local market that are not holidays observed in the United States, the redemption settlement cycle may be extended by the number of such intervening local holidays. In addition to holidays, other unforeseeable closings in a foreign market due to emergencies may also prevent the Trust from delivering securities within two or three Business Days, as applicable.

The securities delivery cycles currently practicable for transferring portfolio securities to redeeming investors, coupled with local market holiday schedules, may require a delivery process longer than the standard settlement period. In certain circumstances during the calendar year, the settlement period may be greater than seven calendar days.

The financial statements and financial highlights of the Funds that were operating during the year ended June 30, 2021, along with the Reports of [ ], the Trust’s Independent Registered Public Accounting Firm, included in the Trust’s Annual Reports to Shareholders on Form N-CSR under the 1940 Act, are incorporated by reference into this Statement of Additional Information.

The Boards of Trustees of the Trusts have adopted the following policy and procedures with respect to voting proxies relating to portfolio securities held by the Trusts’ investment portfolios.

The policy of each Trust is to delegate the responsibility for voting proxies relating to portfolio securities held by the Trusts to SSGA Funds Management, Inc. (the “Adviser”), investment adviser to each series of the Trusts (the “Funds”), subject to the Trustees’ continuing oversight.

The right to vote proxies with respect to portfolio securities held by each Trust is an asset of the Trusts. The Adviser acts as a fiduciary of the Trusts and must vote proxies in a manner consistent with the best interest of the Trusts and the Funds’ shareholders.

The delegation by the Trustees of the authority to vote proxies relating to portfolio securities of the Trusts may be revoked by the Trustees, in whole or in part, at any time.

The Adviser shall provide the required data for each proxy voted with respect to portfolio securities of a Trust to that respective Trust or its designated service provider in a timely manner and in a format acceptable to be filed in the Trust’s annual proxy voting report on Form N-PX for the twelve-month period ended June 30. Form N-PX is required to be filed not later than August 31 of each year.

The Adviser will periodically sample proxy votes to review whether they complied with the Policy. The Adviser shall, at least annually, report to the Board regarding the frequency and results of the sampling performed.

For certain Funds, the Adviser retains investment management firms (“Sub-advisers”) to provide day-to-day investment management services to the Funds pursuant to sub-advisory agreements. It is the policy of the Trust that the Adviser may delegate proxy voting authority with respect to a Fund to a Sub-adviser. Pursuant to such delegation, a Sub-adviser is authorized to vote proxies on behalf of the applicable Fund or Funds for which it serves as sub-adviser, in accordance with the Sub-adviser’s proxy voting policies and procedures.

The Trustees shall review this policy to determine its continued sufficiency as necessary from time to time.

The Board of Trustees of the Trust is the same as the Boards of Trustees of SPDR Index Shares Funds and SSGA Active Trust. In addition, the officers of the Trust are substantially identical to the officers of SPDR Index Shares Funds and SSGA Active Trust. Additionally, the Trust’s investment adviser, SSGA FM, also serves as investment adviser to each series of SPDR Index Shares Funds and SSGA Active Trust. Nonetheless, the Trust takes the position that it is not under common control with other trusts because the power residing in the respective boards and officers arises as the result of an official position with the respective trusts.

Additionally, see the “Control Persons and Principal Holders of Securities” section of the Statement of Additional Information for a list of shareholders who own more than 5% of a specific fund’s outstanding shares and such information is incorporated by reference to this Item.

Pursuant to Section 5.3 of the Registrant’s Amended and Restated Declaration of Trust and under Section 4.9 of the Registrant’s By-Laws, the Trust will indemnify any person who is, or has been, a Trustee, officer, employee or agent of the Trust against all expenses reasonably incurred or paid by him/her in connection with any claim, action, suit or proceeding in which he/she becomes involved as a party or otherwise by virtue of his/her being or having been a Trustee, officer, employee or agent and against amounts paid or incurred by him/her in the settlement thereof, if he/she acted in good faith and in a manner he/she reasonably believed to be in or not opposed to the best interests of the Trust, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his/her conduct was unlawful. In addition, indemnification is permitted only if it is determined that the actions in question did not render him/her liable by reason of willful misfeasance, bad faith or gross negligence in the performance of his/her duties or by reason of reckless disregard of his/her obligations and duties to the Registrant. The Registrant may also advance money for litigation expenses provided that Trustees, officers, employees and/or agents give their undertakings to repay the Registrant unless their conduct is later determined to permit indemnification.

Pursuant to Section 5.2 of the Registrant’s Amended and Restated Declaration of Trust, no Trustee, officer, employee or agent of the Registrant shall be liable for any action or failure to act, except in the case of willful misfeasance, bad faith or gross negligence or reckless disregard of duties to the Registrant. Pursuant to paragraph 9 of the Registrant’s Investment Advisory Agreement, the Adviser shall not be liable for any action or failure to act, except in the case of willful misfeasance, bad faith or gross negligence or reckless disregard of duties to the Registrant.

Insofar as indemnification for liability arising under the Securities Act of 1933 (the “Act”) may be permitted to directors, officers and controlling persons of the Registrant pursuant to the provisions of Rule 484 under the Act, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The Registrant hereby undertakes that it will apply the indemnification provision of its By-Laws in a manner consistent with Release 11330 of the SEC under the Investment Company Act of 1940, as amended (the “1940 Act”), so long as the interpretation of Sections 17(h) and 17(i) thereunder remains in effect.

The Registrant maintains insurance on behalf of any person who is or was a Trustee, officer, employee or agent of the Registrant, or who is or was serving at the request of the Registrant as a trustee, director, officer, employee or agent of another trust or corporation, against any liability asserted against him/her and incurred by him/her or arising out of his/her position. However, in no event will the Registrant maintain insurance to indemnify any such person for any act for which the Registrant itself is not permitted to indemnify him/her.

Any other business, profession, vocation or employment of a substantial nature in which each director or principal officer of each investment adviser is or has been, at any time during the last two fiscal years, engaged for his or her own account or in the capacity of director, officer, employee, partner or trustee are as follows:
