Summary

The Capped Leveraged Index Return Notes^® Linked to the Invesco S&P 500^® Equal Weight ETF, due September 26, 2025 (the “notes”) are our senior unsecured debt securities. The notes are not guaranteed or insured by the Canada Deposit Insurance Corporation, the U.S. Federal Deposit Insurance Corporation or any other governmental agency of the United States, Canada or any other jurisdiction or secured by collateral. The notes are not bail-inable debt securities (as defined on page 6 of the prospectus). The notes will rank equally with all of our other unsecured and unsubordinated debt. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of CIBC. The notes provide you a leveraged return, subject to a cap, if the Ending Value of the Market Measure, which is the Invesco S&P 500^® Equal Weight ETF (the “Underlying Fund”), is greater than the Starting Value. If the Ending Value is equal to or less than the Starting Value but greater than or equal to the Threshold Value, you will receive the principal amount of your notes. If the Ending Value is less than the Threshold Value, you will lose a portion, which could be significant, of the principal amount of your notes. Any payments on the notes will be calculated based on the $10 principal amount per unit and will depend on the performance of the Underlying Fund, subject to our credit risk. See “Terms of the Notes” below.

The economic terms of the notes (including the Capped Value) are based on our internal funding rate, which is the rate we would pay to borrow funds through the issuance of market-linked notes, and the economic terms of certain related hedging arrangements. Our internal funding rate is typically lower than the rate we would pay when we issue conventional fixed rate debt securities. This difference in funding rate, as well as the underwriting discount and the hedging-related charge and certain service fee described below, reduced the economic terms of the notes to you and the initial estimated value of the notes on the pricing date. Due to these factors, the public offering price you pay to purchase the notes is greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value for the notes. This initial estimated value was determined based on our pricing models, and was based on our internal funding rate on the pricing date, market conditions and other relevant factors existing at that time, and our assumptions about market parameters. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-14.

Investor Considerations

We urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Hypothetical Payout Profile and Examples of Payments at Maturity

The following table and examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes. They illustrate the calculation of the Redemption Amount and total rate of return based on a hypothetical Starting Value of 100.00, a hypothetical Threshold Value of 90.00, the Participation Rate of 200%, the Capped Value of $12.486 per unit and a range of hypothetical Ending Values. The actual amount you receive and the resulting total rate of return will depend on the actual Starting Value, Threshold Value and Ending Value, and whether you hold the notes to maturity. The following examples do not take into account any tax consequences from investing in the notes.

For recent actual prices of the Underlying Fund, see “The Underlying Fund” section below. All payments on the notes are subject to issuer credit risk.

Redemption Amount Calculation Examples

Example 1
The Ending Value is 50.00, or 50.00% of the Starting Value:
Starting Value: 100.00
Threshold Value: 90.00
Ending Value: 50.00
	= $6.000 Redemption Amount per unit
Example 2
The Ending Value is 97.00, or 97.00% of the Starting Value:
Starting Value: 100.00
Threshold Value: 90.00
Ending Value: 97.00
Redemption Amount (per unit) = $10.000, the principal amount, since the Ending Value is less than the Starting Value but equal to or greater than the Threshold Value.
Example 3
The Ending Value is 102.00, or 102.00% of the Starting Value:
Starting Value: 100.00
Ending Value: 102.00
	= $10.400 Redemption Amount per unit
Example 4
The Ending Value is 130.00, or 130.00% of the Starting Value:
Starting Value: 100.00
Ending Value: 130.00
	= $16.000, however, because the Redemption Amount for the notes cannot exceed the Capped Value, the Redemption Amount will be $12.486 per unit

Risk Factors

The Underlying Fund

All disclosures contained in this term sheet regarding the Underlying Fund and the Underlying Index, including, without limitation, their make-up, method of their calculation, and changes in their components, have been derived from publicly available sources which we have not independently verified. The information reflects the policies of, and is subject to change by, Invesco Capital Management LLC, which is the investment advisor of the Underlying Fund. The consequences of any discontinuance of the Underlying Fund or the Underlying Index are discussed in the section entitled “Description of LIRNs—Anti-Dilution and Discontinuance Adjustments Relating to Underlying Funds—Discontinuance of or Material Change to an Underlying Fund” beginning on page PS-30 of product supplement EQUITY LIRN-1. None of us, the calculation agent, MLPF&S or BofAS accepts any responsibility for the calculation, maintenance, or publication of the Underlying Fund, the Underlying Index, or any successor fund or index.

The Invesco S&P 500^® Equal Weight ETF

The shares of the Underlying Fund are issued by Invesco Exchange-Traded Fund Trust (the “Invesco Trust”), a registered investment company. The Underlying Fund seeks investment results that correspond generally to the performance, before fees and expenses, of the of the S&P 500^® Equal Weight Index (the “Underlying Index”). The Underlying Index is an equal-weighted version of the S&P 500^® Index (“SPX”). The Underlying Fund is the successor to the investment performance of the Guggenheim S&P 500^® Equal Weight ETF (the “Predecessor Fund”) as a result of the reorganization of the Predecessor Fund into the Underlying Fund, which was consummated after the close of business on April 6, 2018. The Underlying Fund trades on the NYSE Arca under the ticker symbol “RSP.”

Information provided to or filed with the SEC by the Invesco Trust pursuant to the Securities Act of 1933 and the Investment Company Act of 1940 can be located by reference to SEC file numbers 333-102228 and 811-21265, respectively, through the SEC’s website at http://www.sec.gov.

Investment Approach

The Underlying Fund uses an “indexing” investment approach to seek to track the investment results, before fees and expenses, of the Underlying Index. The Underlying Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that it generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. The Underlying Fund will generally invest at least 90% of its total assets in the securities that comprise the Underlying Index. However, under various circumstances, it may not be possible or practicable to purchase all of those securities in those same weightings. In those circumstances, the Underlying Fund may purchase a sample of securities in the Underlying Index. A “sampling” methodology means that Invesco uses quantitative analysis to select securities from the Underlying Index universe to obtain a representative sample of securities that have, in the aggregate, investment characteristics similar to the Underlying Index in terms of key risk factors, performance attributes and other characteristics. These include industry weightings, market capitalization, return variability, earnings valuation, yield and other financial characteristics of securities. When employing a sampling methodology, Invesco bases the quantity of holdings in the Underlying Fund on a number of factors, including asset size of the Underlying Fund, and generally expects the Underlying Fund to hold less than the total number of securities in the Underlying Index.

The Underlying Fund’s return may not match the return of the Underlying Index for a number of reasons. For example, the Underlying Fund incurs operating expenses not applicable to the Underlying Index and incurs costs in buying and selling securities, especially when rebalancing the Underlying Fund’s securities holdings to reflect changes in the composition of the Underlying Index. In addition, the performance of the Underlying Fund and the Underlying Index may vary due to asset valuation differences and differences between the Underlying Fund’s portfolio and the Underlying Index resulting from legal restrictions, cost or liquidity constraints.

The S&P 500^® Equal Weight Index

The Underlying Index is the equal weight version of the SPX. The composition of the Underlying Index is the same as the SPX. Constituent changes are incorporated in the Underlying Index as and when they are made in the SPX. When a company is added to the Underlying Index in the middle of the quarter, it takes the weight of the company that it replaced. The one exception is when a company is removed from the Underlying Index at a price of $0.00. In that case, the company’s replacement is added to the Underlying Index at the weight using the previous day’s closing value, or the most immediate prior business day that the deleted company was not valued at $0.00.

The Underlying Index is calculated and maintained in the same manner as the SPX, except that the constituents of the Underlying Index are equally weighted. To calculate an equal-weighted index, the market capitalization for each stock used in the calculation of the index is redefined so that each index constituent has an equal weight in the index at each rebalancing date. In addition to being the product of the stock price, the stock’s shares outstanding and the stock’s investible weight factor (“IWF”), an additional weight factor (“AWF”) is also introduced in the market capitalization calculation to establish equal weighting. The AWF of a stock is the adjustment factor of that stock assigned at each index rebalancing date that makes all index constituents’ modified market capitalization equal (and, therefore, equal weight), while maintaining the total market value of the overall index.

The S&P 500^® Index

The SPX consists of stocks of 500 companies selected to provide a performance benchmark for the U.S. equity markets. The SPX is one of the multiple indices published by SPDJI (the “the S&P U.S. Indices”). The SPX is reported by Bloomberg L.P. under the ticker symbol “SPX.”

Composition of the S&P U.S. Indices

Securities must meet the following eligibility factors to be considered eligible for inclusion in the S&P U.S. Indices. Constituent selection is at the discretion of the SPDJI’s U.S. index committee (the “Index Committee”) and is based on the eligibility criteria.

Changes to the S&P U.S. Indices are made as needed, with no scheduled reconstitution. Rather, changes in response to corporate actions and market developments can be made at any time. Constituent changes are typically announced two to five days before they are scheduled to be implemented.

Additions to the S&P U.S. Indices are evaluated based on the following eligibility criteria:

In situations where the only factor suggesting that a company is not a U.S. company is its tax registration in a “domicile of convenience” or another location chosen for tax-related reasons, SPDJI normally determines that the company is still a U.S. company. The final determination of domicile eligibility is made by the Index Committee, which can consider other factors including, but not limited to, operational headquarters location, ownership information, location of officers, directors and employees, investor perception and other factors deemed to be relevant.

SPDJI believes turnover in membership in the S&P U.S. Indices should be avoided when possible. At times a stock may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to the S&P U.S. Indices, not for continued membership. As a result, a constituent of the S&P U.S. Indices that appears to violate criteria for addition to the S&P U.S. Indices is not deleted unless ongoing conditions warrant an index change.

Calculation of the S&P U.S. Indices

The S&P U.S. Indices are float-adjusted market capitalization-weighted indices. On any given day, the index value of each S&P U.S. Index is the total float-adjusted market capitalization of that S&P U.S. Index’s constituents divided by its divisor. The float-adjusted market capitalization reflects the price of each stock in the relevant S&P U.S. Index multiplied by the number of shares used in the index value calculation.

Float Adjustment. Float adjustment means that the number of shares outstanding is reduced to exclude closely held shares from the calculation of the index value because such shares are not available to investors. The goal of float adjustment is to distinguish between strategic (control) shareholders, whose holdings depend on concerns such as maintaining control rather than shorter term economic fortunes of the company, and those holders whose investments depend on the stock’s price and their evaluation of a company’s future prospects. Generally, these “control holders” include officers and directors, private equity, venture capital & special equity firms, asset managers and insurance companies with board of director representation, other publicly traded companies that hold shares for control, holders of restricted shares, company-sponsored employee share plans/trusts, defined contribution plans/savings and investment plans, foundations or family trusts associated with the company, holders of unlisted share classes of stock or government entities at all levels (other than government retirement/pension funds), sovereign wealth funds and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. Shares that are not considered outstanding are also not included in the available float. These generally include treasury stock, stock options, equity participation units, warrants, preferred stock, convertible stock and rights.

For each component, SPDJI calculates an IWF, which represents the portion of the total shares outstanding that are considered part of the public float for purposes of the relevant S&P U.S. Index.

Divisor. Continuity in the value of each S&P U.S. Index is maintained by adjusting its divisor for all changes in its constituents’ share capital after its base date. This includes additions and deletions to the relevant S&P U.S. Index, rights issues, share buybacks and issuances and non-zero price spin-offs. The value of each S&P U.S. Index’s divisor over time is, in effect, a chronological summary of all changes affecting the base capital of that S&P U.S. Index. The divisor of each S&P U.S. Index is adjusted such that the index value of that S&P U.S. Index at an instant just prior to a change in base capital equals the index value of that S&P U.S. Index at an instant immediately following that change.

The following types of corporate actions would require a divisor adjustment: company added/deleted, change in shares outstanding, change in IWF, special dividend and rights offering. Stock splits and stock dividends do not affect the divisor, because following a split or dividend, both the stock price and number of shares outstanding are adjusted by SPDJI so that there is no change in the market value of the relevant component. All stock split and dividend adjustments are made after the close of trading on the day before the ex-date.

Maintenance of the S&P U.S. Indices

Changes in response to corporate actions and market developments can be made at any time. Constituent changes are typically implemented with at least three business days advance notice.

Removals. Removals from the S&P U.S. Indices are evaluated based as follows:

Any company that is removed from the S&P U.S. Indices must wait a minimum of one year from its index removal date before being reconsidered as a replacement candidate.

Share Updates. When total shares outstanding increase by at least 5%, but the new share issuance is to a strategic or major shareholder, it implies that there is no change in float- adjusted shares. However, in such instances, SPDJI will apply the share change

and resulting IWF change regardless of whether the float change is greater than or equal to 5%. For companies with multiple share class lines, the 5% share change threshold is based on each individual multiple share class line rather than total company shares. Changes to share counts that is less than 5% of total shares are accumulated and made quarterly on the third Friday of March, June, September and December.

IWF Updates. Accelerated implementation for events less than $1 billion will include an adjustment to the company’s IWF only to the extent that such an IWF change helps the new float share total mimic the shares available in the offering. To minimize unnecessary turnover, these IWF changes do not need to meet any minimum threshold requirement for implementation. Any IWF change resulting in an IWF of 0.96 or greater is rounded up to 1.00 at the next annual IWF review.

IWF changes will only be made at the quarterly review if the change represents at least 5% of total current shares outstanding and is related to a single corporate action that did not qualify for the accelerated implementation rule.

Quarterly share change events resulting from the conversion of derivative securities, acquisitions of private companies, or acquisitions of non-index companies that do not trade on a major exchange are considered to be available to investors unless there is explicit information stating that the new owner is a strategic holder.

Other than the situations described above, IWF changes are only made at the annual IWF review.

Share/IWF Freezes. A share/IWF freeze period is implemented during each quarterly rebalancing. The freeze period begins after the market close on the Tuesday preceding the second Friday of each rebalancing month (i.e. March, June, September and December) and ends after the market close on the third Friday of a rebalancing month. Pro-forma files are normally released after the market close on the second Friday, one week prior to the rebalancing effective date. In September, preliminary share and float data are released on the first Friday of the month. However, the share freeze period for September follows the same schedule as the other three quarterly share freeze periods. For illustration purposes, if rebalancing pro-forma files are scheduled to be released on Friday, March 5, the share/IWF freeze period will begin after the close of trading on Tuesday, March 9 and will end after the close of trading the following Friday, March 19 (i.e. the third Friday of the rebalancing month).

During the share/IWF freeze period, shares and IWFs are not changed except for certain corporate action events (such as merger activity, stock splits, and rights offerings), and the accelerated implementation rule is suspended. The suspension includes all changes that qualify for accelerated implementation and would typically be announced or effective during the share/IWF freeze period. At the end of the freeze period, all suspended changes will be announced on the third Friday of the rebalancing month and implemented five business days after the quarterly rebalancing effective date.

In general, companies that are the target of a cash M&A event that is expected to close by quarter end according to publicly available guidance may have their share count frozen at their current level for rebalancing purposes.

Corporate Actions. As specified in “—Calculation of the S&P U.S. Indices—Divisor” above, the divisor will be adjusted for certain corporation actions. Corporate actions (such as stock splits, stock dividends, non-zero price spin-offs and rights offerings) are applied after the close of trading on the day prior to the ex-date.

Other Adjustments. In cases where there is no achievable market price for a stock being deleted, it can be removed at a zero or minimal price at the Index Committee’s discretion, in recognition of the constraints faced by investors in trading bankrupt or suspended stocks.

The following graph shows the daily historical performance of the Underlying Fund on its primary exchange in the period from January 1, 2013 through September 28, 2023. We obtained this historical data from Bloomberg L.P. We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. On the pricing date, the Closing Market Price of the Underlying Fund was $142.07. The graph below may have been adjusted to reflect certain corporate actions such as stock splits and reverse stock splits.

Historical Performance of the Underlying Fund

This historical data on the Underlying Fund is not necessarily indicative of the future performance of the Underlying Fund or what the value of the notes may be. Any historical upward or downward trend in the price per share of the Underlying Fund during any period set forth above is not an indication that the price per share of the Underlying Fund is more or less likely to increase or decrease at any time over the term of the notes.

Before investing in the notes, you should consult publicly available sources for the prices and trading pattern of the Underlying Fund.

Supplement to the Plan of Distribution

Under our distribution agreement with BofAS, BofAS will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount. MLPF&S will in turn purchase the notes from BofAS for resale, and it will receive a selling concession in connection with the sale of the notes in an amount up to the full amount of the underwriting discount set forth on the cover of this term sheet.

We will pay a fee to a broker dealer in which an affiliate of BofAS has an ownership interest for providing certain services with respect to this offering, which will reduce the economic terms of the notes to you.

We will deliver the notes against payment therefor in New York, New York on a date that is greater than two business days following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes more than two business days prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The notes will not be listed on any securities exchange. In the original offering of the notes, the notes will be sold in minimum investment amounts of 100 units. If you place an order to purchase the notes, you are consenting to MLPF&S and/or one of its affiliates acting as a principal in effecting the transaction for your account.

MLPF&S and BofAS may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices, and these prices will include MLPF&S’s and BofAS’s trading commissions and mark-ups or mark-downs. MLPF&S and BofAS may act as principal or agent in these market-making transactions; however, neither is obligated to engage in any such transactions. At their discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S and BofAS may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes. Any price offered by MLPF&S or BofAS for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Underlying Fund and the remaining term of the notes. However, none of us, MLPF&S, BofAS or any of our respective affiliates is obligated to purchase your notes at any price or at any time, and we cannot assure you that we, MLPF&S, BofAS or any of our respective affiliates will purchase your notes at a price that equals or exceeds the initial estimated value of the notes.

The value of the notes shown on your account statement will be based on BofAS’s estimate of the value of the notes if BofAS or another of its affiliates were to make a market in the notes, which it is not obligated to do. That estimate will be based upon the price that BofAS may pay for the notes in light of then-prevailing market conditions, and other considerations, as mentioned above, and will include transaction costs. At certain times, this price may be higher than or lower than the initial estimated value of the notes.

The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding CIBC or for any purpose other than that described in the immediately preceding sentence.

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Underlying Fund. As is the case for all of our debt securities, including our market-linked notes, the economic terms of the notes reflect our actual or perceived creditworthiness at the time of pricing. The internal funding rate we use in pricing the market-linked notes is typically lower than the rate we would pay when we issue conventional fixed-rate debt securities of comparable maturity. This difference is based on, among other things, our view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. This generally relatively lower internal funding rate, which is reflected in the economic terms of the notes, along with the fees and charges associated with market-linked notes, resulted in the initial estimated value of the notes on the pricing date being less than their public offering price.

At maturity, we are required to pay the Redemption Amount to holders of the notes, which will be calculated based on the performance of the Underlying Fund and the $10 per unit principal amount. In order to meet these payment obligations, at the time we issue the notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with BofAS or one of its affiliates. The terms of these hedging arrangements are determined by seeking bids from market participants, including BofAS and its affiliates, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Underlying Fund , the tenor of the notes and the tenor of the hedging arrangements. The economic terms of the notes and their initial estimated value depend in part on the terms of these hedging arrangements.

BofAS has advised us that the hedging arrangements will include a hedging-related charge of approximately $0.075 per unit, reflecting an estimated profit to be credited to BofAS from these transactions. Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by BofAS or any third party hedge providers.

Summary of Canadian Federal Income Tax Considerations

In the opinion of Blake, Cassels & Graydon LLP, our Canadian tax counsel, the following summary describes the principal Canadian federal income tax considerations under the Income Tax Act (Canada) and the regulations thereto (the “Canadian Tax Act”) generally applicable at the date hereof to a purchaser who acquires beneficial ownership of a note pursuant to this term sheet and who for the purposes of the Canadian Tax Act and at all relevant times: (a) is neither resident nor deemed to be resident in Canada; (b) deals at arm’s length with CIBC and any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of the note; (c) does not use or hold and is not deemed to use or hold the note in, or in the course of, carrying on a business in Canada; (d) is entitled to receive all payments (including any interest and principal) made on the note; (e) is not a, and deals at arm’s length with any, “specified shareholder” of CIBC for purposes of the thin capitalization rules in the Canadian Tax Act; and (f) is not an entity in respect of which CIBC or any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of, loans or otherwise transfers the note is a “specified entity”, and is not a “specified entity” in respect of such a transferee, in each case, for purposes of the Hybrid Mismatch Proposals, as defined below (a “Non-Resident Holder”). Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

This summary assumes that no amount paid or payable to a holder described herein will be the deduction component of a “hybrid mismatch arrangement” under which the payment arises within the meaning of proposed paragraph 18.4(3)(b) of the Canadian Tax Act contained in the proposals to amend the Canadian Tax Act released by the Minister of Finance (Canada) on April 29, 2022 with respect to “hybrid mismatch arrangements” (the “Hybrid Mismatch Proposals”). Investors should note that the Hybrid Mismatch Proposals are in consultation form, are highly complex, and there remains significant uncertainty as to their interpretation and application. There can be no assurance that the Hybrid Mismatch Proposals will be enacted in their current form, or at all.

This summary is supplemental to and should be read together with the description of material Canadian federal income tax considerations relevant to a Non-Resident Holder owning notes under “Material Income Tax Consequences—Canadian Taxation” in the accompanying prospectus and a Non-Resident Holder should carefully read that description as well.

This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Non-Resident Holder. Non-Resident Holders are advised to consult with their own tax advisors with respect to their particular circumstances.

Based on Canadian tax counsel’s understanding of the Canada Revenue Agency’s administrative policies and having regard to the terms of the notes, interest payable on the notes should not be considered to be “participating debt interest” as defined in the Canadian Tax Act and accordingly, a Non-Resident Holder should not be subject to Canadian non-resident withholding tax in respect of amounts paid or credited or deemed to have been paid or credited by CIBC on a note as, on account of or in lieu of payment of, or in satisfaction of, interest.

Non-Resident Holders should consult their own advisors regarding the consequences to them of a disposition of the notes to a person with whom they are not dealing at arm’s length for purposes of the Canadian Tax Act.

Summary of U.S. Federal Income Tax Consequences

The following discussion is a brief summary of the material U.S. federal income tax considerations relating to an investment in the notes. The following summary is not complete and is both qualified and supplemented by, or in some cases supplements, the discussion entitled “U.S. Federal Income Tax Summary” in product supplement EQUITY LIRN-1, which you should carefully review prior to investing in the notes.

The U.S. federal income tax considerations of your investment in the notes are uncertain. No statutory, judicial or administrative authority directly discusses how the notes should be treated for U.S. federal income tax purposes. In the opinion of our tax counsel, Mayer Brown LLP, it would generally be reasonable to treat the notes as prepaid cash-settled derivative contracts. Pursuant to the terms of the notes, you agree to treat the notes in this manner for all U.S. federal income tax purposes. If this treatment is respected, subject to the discussion in the product supplement concerning the potential application of the “constructive ownership” rules under Section 1260 of the Code, you should generally recognize capital gain or loss upon the sale, exchange, redemption or payment on maturity in an amount equal to the difference between the amount you receive at such time and the amount that you paid for your notes. Such gain or loss should generally be long-term capital gain or loss if you have held your notes for more than one year. Non-U.S. holders should consult the section entitled “U.S. Federal Income Tax Summary—Non-U.S. Holders” in product supplement EQUITY LIRN-1.

The expected characterization of the notes is not binding on the U.S. Internal Revenue Service (the “IRS”) or the courts. Thus, it is possible that the IRS would seek to characterize your notes in a manner that results in tax consequences to you that are different from those described above or in the accompanying product supplement. Such alternate treatments could include a requirement that a holder accrue ordinary income over the life of the notes or treat all gain or loss at maturity as ordinary gain or loss. For a more detailed discussion of certain alternative characterizations with respect to your notes and certain other considerations with respect to your investment in the notes, you should consider the discussion set forth in “U.S. Federal Income Tax Summary” of the product supplement. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the notes for U.S. federal income tax or other tax purposes.

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of the notes for U.S. federal income tax purposes. You should also consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the notes in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.
