ASSET-BACKED AND COMMERCIAL MORTGAGE-BACKED SECURITIES

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.

BONDS

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

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.

COMMON STOCK

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 Fund Shares). Common stocks are susceptible to general stock market fluctuations 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.

CONCENTRATION

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

6

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 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 then total Gross National Product (GNP) Has fallen more than 14%. As of August 2018, the island’s unemployment rate was 9.1%, well above the national average. Unemployment has improved marginally as the rate was over 15% for all of 2010 and 2011, but recent declines are partially attributed to a shrinking labor force, not job creation. High unemployment and weak job growth have contributed to historic outmigration of Puerto Rican residents, with more than 300,000 Puerto Ricans leaving for the U.S. mainland during the last decade. The Puerto Rican government estimates that an additional 14% of the population will leave by 2023, further depleting economic growth prospects.

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 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, Alejandro Garcĺa Padilla declared that Puerto Rico’s “debt is not payable” and Puerto Rico would no longer borrow to address annual budget deficits. Debt restructuring legislation passed in mid-2014 aimed at restructuring public corporations was deemed unconstitutional by a federal court in February 2015 and again on appeal in July 2015. In response to the court ruling, the island’s representative in Washington, D.C. introduced a bill allowing Puerto Rico’s public corporations to be eligible for Chapter 9 bankruptcy filing, which was struck down in federal court and ultimately by the Supreme Court on June 13, 2016.

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. In May 2017, the FOMB commenced a formal restructuring proceeding for Puerto Rico’s general obligation debt, as well as for Puerto Rico Sales Tax Financing Corporation (“COFINA”) bonds secured by a dedicated portion of sales and use taxes. On July 2, 2017, the Puerto Rico Electric Power Authority (“PREPA”) filed for bankruptcy protections under PROMESA for its $9 billion in bond debt and on July 31, 2018 a partial settlement with a portion of the PREPA bondholders was announced outlining a possible restructuring of such debt.

As required by PROMESA, in March 2017 Puerto Rico submitted its first fiscal plan to the FOMB, and has continued to submit numerous updates for the FOMB’s review. 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 numerous revisions to the fiscal plans may demonstrate uncertainty with respect to investments in Puerto Rican bonds. In addition, audited financial statements for the 2016 fiscal year have yet to be released, which leads to difficulty in fully understanding the extent of Puerto Rico’s financial distress.

As of August 2018, Puerto Rico had over $120 billion in outstanding debt and unfunded pension obligations. Securities issued by Puerto Rico and its agencies have been the subject of multiple credit downgrades and each rating agency has continued to maintain a negative outlook on certain Puerto Rico issuers.

In September 2017, Puerto Rico suffered an estimated $80 million damage from Hurricane Maria. This damage is predicted to cause a real decline to GNP of 7.4% in fiscal year 2018, which could further increase outmigration, cause potentially unsustainable operating conditions for the territory’s manufacturers and lead to additional defaults on debt. In February 2018, the U.S. Congress approved a $16 billion aid package as part of a larger budget deal intended to promote Puerto Rico’s recovery, and the latest fiscal plan projects that approximately $86.8 billion of disaster relief funding from public and private sources will be disbursed for the reconstruction effort. The extent to which these expectations are met and the timing for receipt of such assistance will greatly impact Puerto Rico’s projected economic recovery. In 2019, Puerto Rico experienced political protests in response to allegations of misuse of the hurricane relief aid, leading to the resignation of Governor Ricardo Rossello and uncertainty regarding the territory’s future leadership.]

[CONSIDERATIONS REGARDING INVESTMENT IN SECURITIES ISSUED BY GREECE

Recent geopolitical events in the European Union (“EU”), specifically in Greece, may disrupt securities markets and adversely affect global economies and markets. This may lead to increased short-term market volatility and may have adverse long-term effects on world economies and markets generally. Those events as well as other changes in Eurozone economic and political conditions could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of a Fund’s investments. Given the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely affect markets, issuers, and/or foreign exchange rates in other countries.

Such events could possibly lead to default, implementation of capital controls and a potential exit from the Eurozone. Each of these scenarios has potential implications to the markets and a Fund’s investments.

A default or debt restructuring by any European country, including Greece, would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness (which may be located in other countries). These events may have an adverse effect on the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

During its government debt crisis in 2015, Greece’s ability to repay its sovereign debt was in question and the possibility of default was not unlikely. As part of a bailout program implemented by the International Monetary Fund and EU member countries, Greece was required to satisfy certain conditions, including imposition of austerity measures on its population. In August 2016, Greece exited its bailout program and is now on track to finance itself on the international markets, although the austerity measures remain. Although less likely since Greece’s departure from the bailout program, it is still possible that Greece may exit the European Monetary Union, which would result in immediate devaluation of the Greek currency and potential for default. If this were to occur, Greece would face significant risks related to the process of full currency redenomination as well as the resulting instability of Europe in general, which would have a severe adverse effect on the value of securities held by a Fund.

If Greece opts to leave the Eurozone, the economic consequences could be severe for Greece and harmful to its trading partners and banks and others around the world that hold Greek debt. The impact of these actions, especially if they occur in a disorderly fashion, is not clear but could be significant and far-reaching.]

CONVERTIBLE SECURITIES

Convertible securities are bonds, debentures, notes, preferred stocks 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 stocks. Convertible securities generally provide yields higher than the underlying common stocks, 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 stocks and interest rates. When the underlying common stocks decline 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.

8

When the underlying common stocks rise 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 stocks. 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.

FOREIGN CURRENCY TRANSACTIONS

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.

FUTURES CONTRACTS, OPTIONS AND SWAP AGREEMENTS

Each Fund may invest up to 20% of its assets in derivatives, including 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.

Recent legislation calls for new regulation of the derivatives markets. The extent and impact of the regulation is not yet fully known and may not be for some time. 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.

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

9

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.

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. The Trust has filed a notice of eligibility for exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that it is not subject to registration or regulation as a commodity pool operator under the CEA.

Restrictions on Trading in Commodity Interests. With respect to the Funds, the Trust has claimed an exclusion from registration as a commodity pool operator under the CEA pursuant to CFTC Rule 4.5 and, therefore, is not subject to the registration and regulatory requirements of the CEA. 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).

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.

10

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.

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. Key Dodd-Frank Act provisions relating to OTC derivatives require rulemaking by the SEC and the CFTC, not all of which has been proposed or finalized as at the date of this SAI. 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”).

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. However, due to the compliance timeline within the Margin Rules, it is unlikely that the Funds will be required to comply with such initial margin requirements until March 1, 2020. 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

11

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.

Certain additional risk factors related to derivatives are discussed below:

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

12

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.

FUTURE DEVELOPMENTS

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.

HIGH YIELD SECURITIES

Investment in high yield securities 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.

13

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. However, an Index seeks to include primarily high yield securities that the Index provider believes have greater liquidity than the broader high yield securities market as a whole.

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.

ILLIQUID SECURITIES

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 the 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.

INFLATION-PROTECTED OBLIGATIONS

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.

INVESTMENT COMPANIES

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.

LENDING PORTFOLIO SECURITIES

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

14

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.

LEVERAGING

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.

MORTGAGE PASS-THROUGH SECURITIES

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”

15

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 Bloomberg Barclays 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 Bloomberg Barclays 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

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.

16

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.

OTHER SHORT-TERM INSTRUMENTS

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

Preferred securities pay fixed or adjustable rate dividends to investors, and have “preference” over common stock in the payment of dividends and the liquidation of a company’s assets. This means that a company must pay dividends on preferred stock before paying any dividends on its common stock. In order to be payable, distributions on preferred securities must be declared by the issuer’s board of directors. Income payments on typical preferred securities currently outstanding are cumulative, causing dividends and distributions to accrue even if not declared by the board of directors or otherwise made payable. There is no assurance that dividends or distributions on the preferred securities in which a Fund invests will be declared or otherwise made payable.

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.

RATINGS

18

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].

REAL ESTATE INVESTMENT TRUSTS (“REITs”)

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.

REPURCHASE AGREEMENTS

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.

19

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.

RESTRICTED SECURITIES

Restricted securities are securities that are not registered under the Securities Act, but which can be offered and sold to “qualified institutional buyers” under Rule 144A under the Securities Act. Institutional markets for restricted securities have developed as a result of the promulgation of Rule 144A under the Securities Act, which provides a “safe harbor” from Securities Act registration requirements for qualifying sales to institutional investors. When Rule 144A restricted securities present an attractive investment opportunity and meet other selection criteria, a Fund may make such investments whether or not such securities are “illiquid” depending on the market that exists for the particular security. The Board has delegated the responsibility for determining the liquidity of Rule 144A restricted securities that a Fund may invest in to the Adviser. In reaching liquidity decisions, the Adviser may consider the following factors: the frequency of trades and quotes for the security; the number of dealers wishing to purchase or sell the security and the number of other potential purchasers; dealer undertakings to make a market in the security; and the nature of the security and the nature of the marketplace in which it trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer).

REVERSE REPURCHASE AGREEMENTS

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

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

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.

20

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 Agreement 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 will transfer to the U.S. Treasury on a quarterly basis all profits earned during a quarter that exceed a capital reserve amount of $3 billion. 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. As part of the terms, Fannie Mae and Freddie Mac also will be required to reduce their investment portfolios at an annual rate of 15% instead of the previous 10%, which put each of them on track to cut their portfolios to a targeted $250 billion in 2018.

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.

U.S. REGISTERED SECURITIES OF FOREIGN ISSUERS

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.

21

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.

CHINA BOND RISK

Certain Funds may invest in renminbi (“RMB”) denominated fixed income securities of Chinese issuers (“China bonds”). To the extent a 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 Funds 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 and quota 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. Funds 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.

A 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, a 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 Funds are therefore subject to the risk of default or errors on the part of such agent.

RQFII Investment Quota Risk. Investment companies, such as the Funds, 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, each Fund may utilize all or a portion of the Adviser’s RQFII quota granted under RQFII regulations to invest in China bonds.

A Fund’s ability to utilize the Adviser’s RQFII quota may be limited or restricted in several ways and thus, adversely affect the Fund’s ability to achieve its investment objective. For example, the Adviser may allocate its RQFII quota among more than one investor, including the Funds. In such case, the Adviser will determine in its sole discretion the amount to be allocated for use by a Fund, and there can be no assurance that the Adviser will allocate a sufficient portion of its RQFII quota to a Fund to meet that Fund’s

23

investment needs initially or over time. In addition, the RQFII regulations provide that the size of a RQFII’s quota may be reduced or cancelled by the State Administration of Foreign Exchange (“SAFE”) if the RQFII is unable to use its RQFII quota effectively within one year after the quota is granted. Once reduced or cancelled there can be no assurance the Adviser will be able to obtain future increases in its RQFII quota.

It is also possible that the Adviser’s RQFII status could be suspended or revoked. Pursuant to PRC and RQFII regulations, the SAFE is 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 and/or quota or other regulatory sanctions and may adversely affect the portion of the Adviser’s RQFII quota allocated to a Fund. A Fund’s ability to utilize the Adviser’s RQFII quota could be adversely affected in such cases even if the violations arise out of activities unrelated to the Fund or the Fund’s use of a portion of the Adviser’s RQFII quota. 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 or be able to acquire additional RQFII quota. In the event the Adviser is unable to maintain its RQFII status or the RQFII quota allocated to a Fund has become inadequate, 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, a 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.

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, a 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. A Fund is therefore subject to the risk of default or errors on the part of such agents.

24

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. A Fund’s ability to trade through Bond Connect (and hence to pursue its investment strategy) may therefore be adversely affected. In addition, where a 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 a 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 a 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. A 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 a Fund may therefore incur significant trading and realization costs and may even suffer losses when selling such investments. To the extent that a 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 a Fund may default in its obligation to settle the transaction by failure to deliver relevant securities or to make payment.

General PRC-Related Risks

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 a 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 a 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 a 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 a Fund’s portfolio securities.

25

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 a Fund. A 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, a Fund’s return might be adversely affected.

CONFLICTS OF INTEREST RISK

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.

CONTINUOUS OFFERING

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.

Certain affiliates of each Fund and the Adviser may purchase and resell or distribute Fund Shares pursuant to the registration statement of which this SAI is a part.

COUNTERPARTY RISK

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.

26

FUTURES AND OPTIONS TRANSACTIONS

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.

RISKS OF SWAP AGREEMENTS

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

27

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.

TAX RISKS

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.

ADDITIONAL STRATEGY INFORMATION

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 seven members of the Board of Trustees, six of whom are not interested persons of the Trust, as that term is defined in the 1940 Act (“Independent Trustees”). Frank Nesvet, 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.

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.

REMUNERATION OF THE TRUSTEES AND OFFICERS

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 Independent Trustee an annual fee of $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 $60,000 and the Chairman of the Audit Committee receives an additional annual fee of $30,000. The Trust also reimburses each Independent 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 Independent Trustees received during the Trust’s fiscal year ended June 30, 2019.

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.

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.

47

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.

SSGA recognizes and rewards outstanding performance by:

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.

Other Accounts Managed as of June 30, 2019:

The portfolio managers listed above did not beneficially own any interests of any Fund as of June 30, 2019.

Compensation. Portfolio manager compensation at Nuveen Asset Management consists primarily of base pay, an annual cash bonus and long-term incentive payments.

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

The portfolio managers are eligible for an annual cash bonus determined based on the particular portfolio manager’s investment performance, qualitative evaluation and financial performance of Nuveen Asset Management.

A portion of each portfolio manager’s annual cash bonus is based on a fund’s pre-tax investment performance, generally measured over the past one-, three- or five-year periods unless the portfolio manager’s tenure is shorter. Investment performance for each fund generally is determined by evaluating the fund’s performance relative to its benchmark(s) and/or Lipper industry peer group.

A portion of the cash bonus is based on a qualitative evaluation made by each portfolio manager’s supervisor taking into consideration a number of factors, including the portfolio manager’s team collaboration, expense management, support of personnel responsible for asset growth, and his or her compliance with Nuveen Asset Management’s policies and procedures.

The final factor influencing a portfolio manager’s cash bonus is the financial performance of Nuveen Asset Management based on its operating earnings.

48

Certain key employees of Nuveen Asset Management, including certain portfolio managers, have received profits interests in Nuveen Asset Management which entitle their holders to participate in the firm’s growth over time.

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.
