Summary

The Capped Market Index Target-Term Securities^® Linked to the Dow Jones Industrial Average^®, due October  , 2028 (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 with 100% participation in increases in the Market Measure, which is the Dow Jones Industrial Average^® (the “Index”), subject to a cap. If the Index is flat or decreases, you will only receive 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 Index, 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 described below, will reduce 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 will be greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value range for the notes. This initial estimated value range was determined based on our pricing models. The initial estimated value as of the pricing date will be 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-12.

Investor Considerations

You may wish to consider an investment in the notes if:
	§	You anticipate that the Index will increase moderately from the Starting Value to the Ending Value.
	§	You accept that the return on the notes will be zero if the Index does not increase from the Starting Value to the Ending Value.

	§	You are willing to forgo dividends or other benefits of owning the stocks included in the Index.
	§	You are willing to accept a limited or no market for sales prior to maturity, and understand that the market prices for the notes, if any, will be affected by various factors, including our actual and perceived creditworthiness, our internal funding rate and fees and charges on the notes.
	§	You are willing to assume our credit risk, as issuer of the notes, for all payments under the notes, including the Redemption Amount.

The notes may not be an appropriate investment for you if:
	§	You believe that the Index will decrease from the Starting Value to the Ending Value or that it will not increase sufficiently over the term of the notes to provide you with your desired return.
	§	You seek a guaranteed return beyond the Minimum Redemption Amount.
	§	You seek an uncapped return on your investment.
	§	You seek interest payments or other current income on your investment.
	§	You want to receive dividends or other distributions paid on the stocks included in the Index.
	§	You seek an investment for which there will be a liquid secondary market.
	§	You are unwilling or are unable to take market risk on the notes or to take our credit risk as issuer of the notes.

Hypothetical Payout Profile and Examples of Payments at Maturity

The graph below is based on hypothetical numbers and values.

Capped Market Index Target-Term Securities^®   This graph reflects the returns on the notes, based on the Participation Rate of 100%, the Minimum Redemption Amount of $10.00 per unit, and a Capped Value of $15.50 per unit (the midpoint of the Capped Value range of [$15.00 to $16.00]). The blue line reflects the returns on the notes, while the dotted gray line reflects the returns of a direct investment in the stocks included in the Index, excluding dividends.   This graph has been prepared for purposes of illustration only.

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, the Participation Rate of 100%, the Minimum Redemption Amount of $10.00 per unit, a hypothetical Capped Value of $15.50 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, Ending Value and Capped 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 levels of the Market Measure, see “The Index” section below. The Index is a price return index and as such the Ending Value will not include any income generated by dividends paid on the stocks included in the Index, which you would otherwise be entitled to receive if you invested in those stocks directly. In addition, all payments on the notes are subject to issuer credit risk.

Ending Value	Percentage Change from the Starting Value to the Ending Value	Redemption Amount per Unit	Total Rate of Return on the Notes

155.00	55.00%	$15.50(3)	55.00%
180.00	80.00%	$15.50	55.00%

(1) The Redemption Amount per unit will not be less than the Minimum Redemption Amount.

(2) The hypothetical Starting Value of 100.00 used in these examples has been chosen for illustrative purposes only, and does not represent a likely actual Starting Value for the Market Measure.

(3) The Redemption Amount per unit cannot exceed the hypothetical Capped Value.

Redemption Amount Calculation Examples

Example 1
The Ending Value is 90.00, or 90.00% of the Starting Value:
Starting Value:	100.00
Ending Value:	90.00
		= $9.00, however, because the Redemption Amount for the notes cannot be less than the Minimum Redemption Amount, the Redemption Amount will be $10.00 per unit.

Example 2
The Ending Value is 130.00, or 130.00% of the Starting Value:
Starting Value:	100.00
Ending Value:	130.00
		= $13.00 Redemption Amount per unit

Example 3
The Ending Value is 180.00, or 180.00% of the Starting Value:
Starting Value:	100.00
Ending Value:	180.00
		= $18.00, however, because the Redemption Amount for the notes cannot exceed the hypothetical Capped Value, the Redemption Amount will be $15.50 per unit.

Risk Factors

There are important differences between the notes and a conventional debt security. An investment in the notes involves significant risks, including those listed below. You should carefully review the more detailed explanation of risks relating to the notes in the “Risk Factors” sections beginning on page PS-6 of product supplement EQUITY INDICES MITTS-1, page S-1 of the prospectus supplement, and page 1 of the prospectus identified above. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Structure-related Risks

§ Depending on the performance of the Index as measured shortly before the maturity date, you may not receive a positive return on your investment.

§ Your investment return is limited to the return represented by the Capped Value and may be less than a comparable investment directly in the stocks included in the Index.

§ Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

§ Payments on the notes are subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes. If we become insolvent or are unable to pay our obligations, you may lose your entire investment.

Valuation- and Market-related Risks

§ Our initial estimated value of the notes will be lower than the public offering price of the notes. The public offering price of the notes will exceed our initial estimated value because costs associated with selling and structuring the notes, as well as hedging the notes, all as further described in “Structuring the Notes” on page TS-12, are included in the public offering price of the notes.

§ Our initial estimated value does not represent future values of the notes and may differ from others’ estimates. Our initial estimated value is only an estimate, which will be determined by reference to our internal pricing models when the terms of the notes are set. This estimated value will be based on market conditions and other relevant factors existing at that time, our internal funding rate on the pricing date and our assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors. Different pricing models and assumptions could provide valuations for the notes that are greater or less than our initial estimated value. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the market value of the notes could change significantly based on, among other things, changes in market conditions, including the level of the Index, our creditworthiness, interest rate movements and other relevant factors, which may impact the price at which MLPF&S, BofAS or any other party would be willing to buy notes from you in any secondary market transactions. Our estimated value does not represent a minimum price at which MLPF&S, BofAS or any other party would be willing to buy your notes in any secondary market (if any exists) at any time.

§ Our initial estimated value of the notes will not be determined by reference to credit spreads for our conventional fixed-rate debt. The internal funding rate to be used in the determination of our initial estimated value of the notes generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount 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. If we were to use the interest rate implied by our conventional fixed-rate debt, we would expect the economic terms of the notes to be more favorable to you. Consequently, our use of an internal funding rate for market-linked notes would have an adverse effect on the economic terms of the notes, the initial estimated value of the notes on the pricing date, and any secondary market prices of the notes.

§ A trading market is not expected to develop for the notes. None of us, MLPF&S or BofAS is obligated to make a market for, or to repurchase, the notes. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market.

Conflict-related Risks

§ Our business, hedging and trading activities, and those of MLPF&S, BofAS and our respective affiliates (including trades in shares of companies included in the Index), and any hedging and trading activities we, MLPF&S, BofAS or our respective affiliates engage in for our clients’ accounts, may affect the market value and return of the notes and may create conflicts of interest with you.

§ There may be potential conflicts of interest involving the calculation agent, which is BofAS. We have the right to appoint and remove the calculation agent.

Market Measure-related Risks

§ The Index sponsor may adjust the Index in a way that affects its level, and has no obligation to consider your interests.

§ You will have no rights of a holder of the securities represented by the Index, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

§ While we, MLPF&S, BofAS or our respective affiliates may from time to time own securities of companies included in the Index, we, MLPF&S, BofAS and our respective affiliates do not control any company included in the Index, and have not verified any disclosure made by any other company.

Tax-related Risks

§ The U.S. federal income tax consequences of the notes are uncertain, and may be adverse to a holder of the notes. See “Summary of U.S. Federal Income Tax Consequences” below and “U.S. Federal Income Tax Summary” beginning on page PS-25 of product supplement EQUITY INDICES MITTS-1. For a discussion of the Canadian federal income tax consequences of investing in the notes, see “Material Income Tax Consequences—Canadian Taxation” in the prospectus, as supplemented by the discussion under “Summary of Canadian Federal Income Tax Considerations” herein.

The Index

All disclosures contained in this term sheet regarding the Index, including, without limitation, its make-up, method of calculation and changes in its 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, S&P Dow Jones Indices LLC (“SPDJI” or the “Index sponsor”). The Index sponsor, which licenses the copyright and all other rights to the Index, has no obligation to continue to publish, and may discontinue publication of, the Index. The consequences of the Index sponsor discontinuing publication of the Index are discussed in the section entitled “Description of MITTS—Discontinuance of an Index” beginning on page PS-18 of product supplement EQUITY INDICES MITTS-1. None of us, the calculation agent, MLPF&S or BofAS accepts any responsibility for the calculation, maintenance or publication of the Index or any successor index.

The Index is a price-weighted index of 30 U.S. blue-chip stocks, which represent all economic industries except transportation and utilities. The Index was launched on May 26, 1896 with a base date of May 26, 1896. The Index is published by SPDJI and is reported by Bloomberg under the ticker symbol “INDU.”

Index Construction and Maintenance

The Index is maintained by the “Averages Committee,” which is composed of three representatives of SPDJI and two representatives of The Wall Street Journal. The Averages Committee meets regularly to review pending corporate actions that may affect index constituents, statistics comparing the composition of the Index to the market, companies that are being considered as candidates for addition to the Index and any significant market events.

The index universe for the Index consists of securities in the S&P 500^® Index excluding stocks classified under Global Industry Classification Standard (“GICS”) code 2030 (Transportation) and 55 (Utilities). While stock selection is not governed by quantitative rules, a stock typically is added only if the company has an excellent reputation, demonstrates sustained growth and is of interest to a large number of investors. Companies should be incorporated and headquartered in the United States. In addition, a plurality of revenues should be derived from the United States. Maintaining adequate sector representation within the index is also a consideration in the selection process for the Index.

Changes to the Index are made on an as-needed basis. There is no annual or semi-annual reconstitution. Rather, changes in response to corporate actions and market developments can be made at any time. Constituent changes are typically announced one to five days before they are scheduled to be implemented.

Index Computation

The Index is a price-weighted index rather than a market capitalization-weighted index and therefore Index constituent weights are determined solely by the prices of the constituent stocks in the Index.

The formula to calculate the Index is:

where,

P = the price of each constituent stock in the index

Shares outstanding are set to a uniform number throughout the Index and the index divisor is adjusted for any price impacting corporate action on one of its member stocks; this includes price adjustments, special dividends, stock splits and rights offerings. The index divisor will also adjust in the event of an addition to or deletion from the index. The Index is calculated without adjustments for regular cash dividends.

Corporate actions (such as stock splits, stock dividends, and rights offerings) are applied after the close of trading on the day prior to the ex-date. Any potential impact of a spin-off on constituents of the Index is evaluated by the Averages Committee on a case-by-case basis.

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 may 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, if the initial settlement of the notes occurs more than two business days from the pricing date, 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 Index 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.

An investor’s household, as referenced on the cover of this term sheet, will generally include accounts held by any of the following, as determined by MLPF&S in its discretion and acting in good faith based upon information then available to MLPF&S:

• the investor’s spouse (including a domestic partner), siblings, parents, grandparents, spouse’s parents, children and grandchildren, but excluding accounts held by aunts, uncles, cousins, nieces, nephews or any other family relationship not directly above or below the individual investor;

• a family investment vehicle, including foundations, limited partnerships and personal holding companies, but only if the beneficial owners of the vehicle consist solely of the investor or members of the investor’s household as described above; and

• a trust where the grantors and/or beneficiaries of the trust consist solely of the investor or members of the investor’s household as described above; provided that, purchases of the notes by a trust generally cannot be aggregated together with any purchases made by a trustee’s personal account.

Purchases in retirement accounts will not be considered part of the same household as an individual investor’s personal or other non-retirement account, except for individual retirement accounts (“IRAs”), simplified employee pension plans (“SEPs”), savings incentive match plan for employees (“SIMPLEs”), and single-participant or owners only accounts (i.e., retirement accounts held by self-employed individuals, business owners or partners with no employees other than their spouses).

Please contact your Merrill financial advisor if you have any questions about the application of these provisions to your specific circumstances or think you are eligible.

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Index. 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, typically results 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 Index 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 Index, 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 is a “specified entity” for purposes of the Hybrid Mismatch Proposals, as defined below (a “Non-Resident Holder”). For these purposes, a “specified shareholder” generally includes a person who (either alone or together with persons with whom that person is not dealing at arm’s length for the purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own 25% or more of CIBC’s shares determined on a votes or fair market value basis, and an entity in respect of which CIBC is a “specified entity” generally includes (i) an entity that is a specified shareholder of CIBC (as defined above), (ii) an entity in which CIBC (either alone or together with entities with whom CIBC is not dealing at arm’s length for purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own a 25% or greater equity interest, and (iii) an entity in which an entity described in (i) (either alone or together with entities with whom such entity is not dealing at arm’s length for purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own a 25% or greater equity interest . Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

For greater certainty, this summary takes into account all specific proposals to amend the Canadian Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof, including the proposals released on April 29, 2022 with respect to “hybrid mismatch arrangements” (the “Hybrid Mismatch Proposals”). 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 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

You should consider the U.S. federal income tax consequences of an investment in the notes, including the following:

· There is no statutory, judicial, or administrative authority directly addressing the characterization of the notes.

· We intend to take the position that the notes will be treated as “contingent payment debt instruments” for U.S. federal income tax purposes, subject to taxation under the “noncontingent bond method.” No assurance can be given that the Internal Revenue Service or any court will agree with this characterization and tax treatment.

· Under this characterization and tax treatment of the notes, a U.S. holder will be required to report original issue discount (“OID”) or interest income based on a “comparable yield” and a “projected payment schedule” with respect to a note without regard to cash, if any, received on the notes.

· The following table is based upon a hypothetical projected payment schedule (including a hypothetical Redemption Amount) and a hypothetical comparable yield equal to 5.2090% per annum (compounded annually). The hypothetical comparable yield is our current estimate of the comparable yield based upon market conditions as of the date of this term sheet. It has been determined by us for purposes of illustrating the application of the Code and the Treasury regulations to the notes as if the notes had been issued on November 3, 2022 and were scheduled to mature October 27, 2028. This tax accrual table is based upon a hypothetical projected payment schedule per $10 principal amount of the notes, which would consist of a single payment of $13.5506 at maturity. The following table is for illustrative purposes only, and we make no representations or predictions as to what the actual Redemption Amount will be. The actual “projected payment schedule” will be completed on the pricing date, and included in the final term sheet.

Accrual Period	Interest Deemed to Accrue on the Notes During Accrual Period per Unit	Total Interest Deemed to Have Accrued on the Notes as of End of Accrual Period per Unit
November 3, 2022 through December 31, 2022	0.2113	0.2113
January 1, 2023 through December 31, 2023	0.5319	0.7432
January 1, 2024 through December 31, 2024	0.5596	1.3028
January 1, 2025 through December 31, 2025	0.5888	1.8915
January 1, 2026 through December 31, 2026	0.6194	2.5110
January 1, 2027 through December 31, 2027	0.6517	3.1627
January 1, 2028 through October 27, 2028	0.3880	3.5506

Hypothetical Projected Redemption Amount = $13.5506 per unit of the notes.

· Upon a sale, exchange, or retirement of a note prior to maturity, a U.S. holder generally will recognize taxable gain or loss equal to the difference between the amount realized on the sale, exchange, or retirement and the holder’s tax basis in the notes. A U.S. holder generally will treat any gain as ordinary interest income, and any loss as ordinary up to the amount of previously accrued OID and then as capital loss. At maturity, (i) if the actual Redemption Amount exceeds the projected Redemption Amount, a U.S. holder must include such excess as interest income, or (ii) if the projected Redemption Amount exceeds the actual Redemption Amount, a U.S. holder will generally treat such excess first as an offset to previously accrued OID for the taxable year, then as an ordinary loss to the extent of all prior OID inclusions, and thereafter as a capital loss.

With respect to the discussion in the product supplement regarding “dividend equivalent” payments, the IRS has issued a notice that provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2025.

You should consult your own tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the notes, as well as any tax consequences arising under the laws of any state, local, foreign, or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws. You should review carefully the discussion under the section entitled “U.S. Federal Income Tax Summary” beginning on page PS-25 of product supplement EQUITY INDICES MITTS-1.
