This pricing supplement, which is not complete and may be changed, relates to an effective Registration Statement under the Securities Act of 1933. This pricing supplement and the accompanying product supplement, prospectus supplement and prospectus are not an offer to sell these notes in any country or jurisdiction where such an offer would not be permitted.

Linked to the Least Performing of the Common Stock of Advanced Micro Devices, Inc., the Common Stock of Target Corporation and the Common Stock of Tesla, Inc.

The initial estimated value of the Notes as of the pricing date is expected to be between $890.00 and $950.00 per $1,000 in principal amount of Notes, which is less than the public offering price listed below. The actual value of your Notes at any time will reflect many factors and cannot be predicted with accuracy. See “Risk Factors” beginning on page PS-9 of this pricing supplement and “Structuring the Notes” on page PS-17 of this pricing supplement for additional information.

There are important differences between the Notes and a conventional debt security. Potential purchasers of the Notes should consider the information in “Risk Factors” beginning on page PS-9 of this pricing supplement, page PS-5 of the accompanying product supplement, page S-6 of the accompanying prospectus supplement, and page 7 of the accompanying prospectus.

None of the Securities and Exchange Commission (the “SEC”), any state securities commission, or any other regulatory body has approved or disapproved of these securities or determined if this pricing supplement and the accompanying product supplement, prospectus supplement and prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

Terms of the Notes

Provided that the Notes have not previously been automatically called, the Notes provide a monthly Fixed Coupon Payment of at least $7.75 per $1,000 in principal amount of Notes on the applicable Fixed Payment Date. The actual Fixed Coupon Payment will be determined on the pricing date.

Beginning in July 2024, if the Observation Value of each Underlying Stock is greater than or equal to its Call Value on any Observation Date, the Notes will be automatically called, in whole but not in part, at 100% of the principal amount, together with a Fixed Coupon Payment. No further amounts will be payable following an Automatic Call. If the Notes are not automatically called prior to maturity and (i) each Underlying Stock declines from its Starting Value and (ii) the Least Performing Underlying Stock declines by more than 40% from its Starting Value, there is full exposure to declines in the Least Performing Underlying Stock, and you will lose a significant portion or all of your investment in the Notes. Otherwise, at maturity you will receive the principal amount. At maturity you will also receive the final Fixed Coupon Payment regardless of the performance of the Least Performing Underlying Stock. It is possible that you may lose a significant portion or all of your investment in the Notes at maturity. Any payments on the Notes will be calculated based on $1,000 in principal amount of Notes and will depend on the performance of the Underlying Stocks, subject to our and BAC’s credit risk.

Amount:
Redemption Amount:	If the Notes have not been automatically called prior to maturity, the Redemption Amount per $1,000 in principal amount of Notes will be:
	a)          If either (i) the Ending Value of any Underlying Stock is greater than or equal to its Starting Value or (ii) the Ending Value of the Least Performing Underlying Stock is greater than or equal to its Threshold Value:
	$1,000; or
	b)          If both (i) the Ending Value of each Underlying Stock is less than its Starting Value and (ii) the Ending Value of the Least Performing Underlying Stock is less than its Threshold Value:
	In this case, the Redemption Amount (excluding the final Fixed Coupon Payment) will be less than 60% of the principal amount and could be zero.
	The Redemption Amount will also include the final Fixed Coupon Payment regardless of the performance of the Least Performing Underlying Stock.

FIXED INCOME AUTO-CALLABLE YIELD NOTES  |  PS-4

Any payments on the Notes depend on the credit risk of BofA Finance, as Issuer, and BAC, as Guarantor, and on the performance of the Underlying Stocks. The economic terms of the Notes are based on BAC’s internal funding rate, which is the rate it would pay to borrow funds through the issuance of market-linked notes, and the economic terms of certain related hedging arrangements BAC’s affiliates enter into. BAC’s internal funding rate is typically lower than the rate it would pay when it issues conventional fixed or floating rate debt securities. This difference in funding rate, as well as the underwriting discount, if any, and the hedging related charges described below (see “Risk Factors” beginning on page PS-9), will reduce the economic terms of the Notes to you and the initial estimated value of the Notes. 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 as of the pricing date.

The initial estimated value range of the Notes is set forth on the cover page of this pricing supplement. The final pricing supplement will set forth the initial estimated value of the Notes as of the pricing date.

Hypothetical Payout Profile and Examples of Payments at Maturity

Fixed Income Auto-Callable Yield Notes Table

The following table is for purposes of illustration only. It assumes the Notes have not been automatically called prior to maturity and is based on hypothetical values and shows hypothetical returns on the Notes. The table illustrates the calculation of the Redemption Amount and the return on the Notes based on a hypothetical Starting Value of 100 for the Least Performing Underlying Stock, a hypothetical Threshold Value of 60 for the Least Performing Underlying Stock, the Fixed Coupon Payment of $7.75 per $1,000 in principal amount of Notes and a range of hypothetical Ending Values of the Least Performing Underlying Stock. The actual amount you receive and the resulting return will depend on the actual Starting Values, Threshold Values and Ending Values of the Underlying Stocks, whether the Notes are automatically called prior to maturity, 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 values of the Underlying Stocks, see “The Underlying Stocks” section below. The Ending Value of each Underlying Stock will not include any income generated by dividends or other distributions paid with respect to shares of that Underlying Stock. In addition, all payments on the Notes are subject to Issuer and Guarantor credit risk.

Risk Factors

Your investment in the Notes entails significant risks, many of which differ from those of a conventional debt security. Your decision to purchase the Notes should be made only after carefully considering the risks of an investment in the Notes, including those discussed below, with your advisors in light of your particular circumstances. The Notes are not an appropriate investment for you if you are not knowledgeable about significant elements of the Notes or financial matters in general. You should carefully review the more detailed explanation of risks relating to the Notes in the “Risk Factors” sections beginning on page PS-5 of the accompanying product supplement, page S-6 of the accompanying prospectus supplement and page 7 of the accompanying prospectus, each as identified on page PS-22 below.

the Guarantor become unable to meet our respective financial obligations as they become due, you may not receive the amount(s) payable under the terms of the Notes.

In addition, our credit ratings and the credit ratings of the Guarantor are assessments by ratings agencies of our respective abilities to pay our obligations. Consequently, our or the Guarantor’s perceived creditworthiness and actual or anticipated decreases in our or the Guarantor’s credit ratings or increases in the spread between the yield on our respective securities and the yield on U.S. Treasury securities (the “credit spread”) prior to the Maturity Date may adversely affect the market value of the Notes. However, because your return on the Notes depends upon factors in addition to our ability and the ability of the Guarantor to pay our respective obligations, such as the prices of the Underlying Stocks, an improvement in our or the Guarantor’s credit ratings will not reduce the other investment risks related to the Notes.

The Underlying Stocks

We have derived the following information on each Underlying Stock and each company issuing an Underlying Stock (each, an “Underlying Company” and, together, the “Underlying Companies”) from publicly available documents. Because each Underlying Stock is registered under the Securities Exchange Act of 1934, the Underlying Companies are required to file periodically certain financial and other information specified by the SEC. Information provided to or filed with the SEC by the Underlying Companies can be located through the SEC’s web site at sec.gov by reference to the applicable CIK number set forth below.

This document relates only to the offering of the Notes and does not relate to any offering of Underlying Stock or any other securities of the Underlying Companies. None of us, the Guarantor, BofAS or any of our other affiliates has made any due diligence inquiry with respect to the Underlying Companies in connection with the offering of the Notes. None of us, the Guarantor, BofAS or any of our other affiliates has independently verified the accuracy or completeness of the publicly available documents or any other publicly available information regarding the Underlying Companies and hence makes no representation regarding the same. Furthermore, there can be no assurance that all events occurring prior to the date of this document, including events that would affect the accuracy or completeness of these publicly available documents that could affect the trading price of the Underlying Stocks, have been or will be publicly disclosed. Subsequent disclosure of any events or the disclosure of or failure to disclose material future events concerning an Underlying Company could affect the price of the applicable Underlying Stock and therefore could affect your return on the Notes. The selection of the Underlying Stocks is not a recommendation to buy or sell the Underlying Stocks.

Supplement to the Plan of Distribution; Role of BofAS and Conflicts of Interest

BofAS, a broker-dealer affiliate of ours, is a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”) and will participate as selling agent in the distribution of the Notes. Accordingly, the offering of the Notes will conform to the requirements of FINRA Rule 5121. BofAS may not make sales in this offering to any of its discretionary accounts without the prior written approval of the account holder.

We expect to 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.

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 pricing supplement, less the indicated underwriting discount, if any. BofAS will sell the Notes to other broker-dealers that will participate in the offering and that are not affiliated with us, at an agreed discount to the principal amount. Each of those broker-dealers may sell the Notes to one or more additional broker-dealers. BofAS has informed us that these discounts may vary from dealer to dealer and that not all dealers will purchase or repurchase the Notes at the same discount. Certain dealers who purchase the Notes for sale to certain fee-based advisory accounts may forgo some or all of their selling concessions, fees or commissions. The public offering price for investors purchasing the Notes in these fee-based advisory accounts may be as low as $965.00 per $1,000 in principal amount of Notes.

BofAS and any of our other broker-dealer affiliates may use this pricing supplement and the accompanying product supplement, prospectus supplement and prospectus for offers and sales in secondary market transactions and market-making transactions in the Notes. However, they are not obligated to engage in such secondary market transactions and/or market-making transactions. These broker-dealer affiliates may act as principal or agent in these transactions, and any such sales will be made at prices related to prevailing market conditions at the time of the sale.

At BofAS’s discretion, for a short, undetermined initial period after the issuance of the Notes, 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 BofAS for the Notes will be based on then-prevailing market conditions and other considerations, including the performance of the Underlying Stocks and the remaining term of the Notes. However, none of us, the Guarantor, BofAS or any of our other affiliates is obligated to purchase your Notes at any price or at any time, and we cannot assure you that any party will purchase your Notes at a price that equals or exceeds the initial estimated value of the Notes.

Any price that BofAS may pay to repurchase the Notes will depend upon then prevailing market conditions, the creditworthiness of us and the Guarantor, and transaction costs. At certain times, this price may be higher than or lower than the initial estimated value of the Notes.

European Economic Area and United Kingdom

None of this pricing supplement, the accompanying product supplement, the accompanying prospectus or the accompanying prospectus supplement is a prospectus for the purposes of the Prospectus Regulation (as defined below). This pricing supplement, the accompanying product supplement, the accompanying prospectus and the accompanying prospectus supplement have been prepared on the basis that any offer of Notes in any Member State of the European Economic Area (the “EEA”) or in the United Kingdom (each, a “Relevant State”) will only be made to a legal entity which is a qualified investor under the Prospectus Regulation (“Qualified Investors”). Accordingly any person making or intending to make an offer in that Relevant State of Notes which are the subject of the offering contemplated in this pricing supplement, the accompanying product supplement, the accompanying prospectus and the accompanying prospectus supplement may only do so with respect to Qualified Investors. Neither BofA Finance nor BAC has authorized, nor does it authorize, the making of any offer of Notes other than to Qualified Investors. The expression “Prospectus Regulation” means Regulation (EU) 2017/1129.

PROHIBITION OF SALES TO EEA AND UNITED KINGDOM RETAIL INVESTORS – The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA or in the United Kingdom. For these purposes: (a) a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended (“MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (the Insurance Distribution Directive) where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation; and (b) the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the Notes to be offered so as to enable an investor to decide to purchase or subscribe for the Notes. Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the “PRIIPs Regulation”) for offering or selling the Notes or otherwise making them available to retail investors in the EEA or in the United Kingdom has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA or in the United Kingdom may be unlawful under the PRIIPs Regulation.

Accordingly, such documents and/or materials are not being distributed to, and must not be passed on to, the general public in the United Kingdom. The communication of such documents and/or materials as a financial promotion is only being made to those persons in the United Kingdom who have professional experience in matters relating to investments and who fall within the definition of investment professionals (as defined in Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005, as amended (the “Financial Promotion Order”)), or who fall within Article 49(2)(a) to (d) of the Financial Promotion Order, or who are any other persons to whom it may otherwise lawfully be made under the Financial Promotion Order (all such persons together being referred to as “relevant persons”).

All applicable provisions of the FSMA must be complied with in respect to anything done by any person in relation to the Notes in, from or otherwise involving the United Kingdom.

Structuring the Notes

The Notes are our debt securities, the return on which is linked to the performance of the Underlying Stocks. The related guarantee is BAC’s obligation. As is the case for all of our and BAC’s respective debt securities, including our market-linked notes, the economic terms of the Notes reflect our and BAC’s actual or perceived creditworthiness at the time of pricing. In addition, because market-linked notes result in increased operational, funding and liability management costs to us and BAC, BAC typically borrows the funds under these types of notes at a rate, which we refer to in this pricing supplement as BAC’s internal funding rate, that is more favorable to BAC than the rate that it might pay for a conventional fixed or floating rate debt security. 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.

In order to meet our payment obligations on the Notes, 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 our other affiliates. The terms of these hedging arrangements are determined based upon terms provided by BofAS and its affiliates, and take into account a number of factors, including our and BAC’s creditworthiness, interest rate movements, the volatility of the Underlying Stocks, the tenor of the Notes and 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 hedging related charges, reflecting the costs associated with, and our affiliates’ profit earned from, these hedging arrangements. Since hedging entails risk and may be influenced by unpredictable market forces, actual profits or losses from these hedging transactions may be more or less than any expected amounts.

U.S. Federal Income Tax Summary

The following summary of the material U.S. federal income and estate tax considerations of the acquisition, ownership, and disposition of the Notes supplements, and to the extent inconsistent supersedes, the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus and is not exhaustive of all possible tax considerations. This summary is based upon the Internal Revenue Code of 1986, as amended (the “Code”), regulations promulgated under the Code by the U.S. Treasury Department (“Treasury”) (including proposed and temporary regulations), rulings, current administrative interpretations and official pronouncements of the IRS, and judicial decisions, all as currently in effect and all of which are subject to differing interpretations or to change, possibly with retroactive effect. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences described below. This summary does not include any description of the tax laws of any state or local governments, or of any foreign government, that may be applicable to a particular holder.

Although the Notes are issued by us, they will be treated as if they were issued by BAC for U.S. federal income tax purposes. Accordingly throughout this tax discussion, references to “we,” “our” or “us” are generally to BAC unless the context requires otherwise.

This summary is directed solely to U.S. Holders and Non-U.S. Holders that, except as otherwise specifically noted, will purchase the Notes upon original issuance and will hold the Notes as capital assets within the meaning of Section 1221 of the Code, which generally means property held for investment, and that are not excluded from the discussion under “U.S. Federal Income Tax Considerations” in the accompanying prospectus.

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.

General

There is no statutory, judicial, or administrative authority directly addressing the characterization of the Notes or instruments substantially similar to the Notes. We intend to treat the Notes for all tax purposes as a unit (a “Unit”) consisting of the following:

Based on the treatment of each Note as a Unit consisting of the Put Option and the Deposit, it would be reasonable to allocate each Fixed Coupon Payment between the Deposit and the Put Option and treat % of each Fixed Coupon Payment as Deposit Interest and % of each Fixed Coupon Payment as Put Option premium. Under this approach, it would be reasonable to allocate 100% of the issue price of a Note to the Deposit and none to the Put Option.

No statutory, judicial or administrative authority directly addresses the proper treatment of the Notes or instruments substantially similar to the Notes for U.S. federal income tax purposes, and no ruling is being requested from the IRS with respect to the Notes. Significant aspects of the U.S. federal income tax consequences of an investment in the Notes are uncertain, and no assurance can be given that the IRS or a court will agree with the tax treatment described herein. In the opinion of our counsel, Sidley Austin LLP, the treatment of the Notes described above is reasonable under current law; however, our counsel has advised us that it is unable to conclude affirmatively that this treatment is more likely than not to be upheld, and that alternative treatments are possible. Accordingly, you should consult your tax advisor regarding the U.S. federal income tax consequences of an investment in the Notes (including alternative treatments of the notes). Unless otherwise expressly stated, the remainder of this discussion is based upon, and assumes, the treatment of each Note as a Unit consisting of the Put Option and the Deposit, as well as the allocation of the Fixed Coupon Payments and issue price of the Note described above.

Unless otherwise stated, the following discussion is based on the characterization described above. The discussion in this section assumes that there is a significant possibility of a significant loss of principal on an investment in the Notes.

We will not attempt to ascertain whether the issuer of any Underlying Stock would be treated as a “passive foreign investment company” (“PFIC”), within the meaning of Section 1297 of the Code, or a United States real property holding corporation, within the meaning of Section 897(c) of the Code. If the issuer of any Underlying Stock were so treated, certain adverse U.S. federal income tax consequences could possibly apply to a holder of the Notes. You should refer to information filed with the SEC by the issuers of the Underlying Stocks and consult your tax advisor regarding the possible consequences to you, if any, if the issuer of any Underlying Stock is or becomes a PFIC or is or becomes a United States real property holding corporation.

U.S. Holders

FIXED INCOME AUTO-CALLABLE YIELD NOTES  |  PS-18

The Deposit Interest payments will be included in the income of a U.S. Holder as interest at the time that such interest is accrued or received in accordance with such U.S. Holder’s regular method of tax accounting. The Put Option premium will not be included in the income of a U.S. Holder until the sale, exchange, redemption or maturity of the Notes. Accordingly, all of the Put Option premium payments on the Notes (except for the last Put Option premium payment) generally will not be included in the income of a U.S. Holder when they are received.

If at maturity the U.S. Holder receives cash equal to the full principal amount plus the last Deposit Interest payment and the last Put Option premium payment, then such U.S. Holder (i) would include the last Deposit Interest payment in income as interest in the manner described above and (ii) would recognize short-term capital gain equal to the entire amount of Put Option premium, which amount is equal to the sum of all of the Put Option premium payments received.

If at maturity the U.S. Holder receives an amount of cash that is less than the full principal amount and receives the last Deposit Interest payment and the last Put Option premium payment, then such U.S. Holder (i) will include the last Deposit Interest payment in income as interest in the manner described above and (ii) will recognize long-term capital gain or loss with respect to the remaining cash received at maturity (other than the last Put Option premium payment) in an amount equal to the difference between (1) the sum of all of the Put Option premiums received (including the last Put Option premium payment) and (2) the excess of the principal amount of the Note over the amount of such cash received.

Upon a redemption of the Notes prior to maturity, a U.S. Holder (i) would include the last Deposit Interest payment in income as interest in the manner described above and (ii) would recognize short-term capital gain equal to the sum of all the Put Option premium payments received.

Upon a sale or exchange of a Note prior to maturity (except upon redemption of the Notes prior to maturity, which is described above), a U.S. Holder will generally recognize short-term or long-term capital gain or loss with respect to the Deposit (depending upon the U.S. Holder’s holding period for the Notes). The U.S. Holder will also generally recognize short-term capital gain or loss with respect to the Put Option. For purposes of determining the amount of such gain or loss, a U.S. Holder should apportion the amount realized on the sale or exchange (other than amounts attributable to accrued but unpaid Deposit Interest payments, which would be taxed as described above) between the Deposit and the Put Option based upon their respective fair market values on the date of such sale or exchange. In general, the amount of capital gain or loss on the Deposit will equal the amount realized that is attributable to the Deposit, less the U.S. Holder’s adjusted tax basis in the Deposit. The amount realized that is attributable to the Put Option plus the total Put Option premiums previously received by the U.S. Holder should be treated as short-term capital gain. Notwithstanding the foregoing, if the fair market value of the Deposit on the date of such sale or exchange exceeds the total amount realized on the sale or exchange (other than amounts attributable to accrued but unpaid Deposit Interest payments), the U.S. Holder should be treated as having (i) sold or exchanged the Deposit for an amount equal to its fair market value on such date and (ii) made a payment (the “Put Option Assumption Payment”) equal to the amount of such excess in exchange for the purchaser’s assumption of the U.S. Holder’s rights and obligations under the Put Option. In such event, the U.S. Holder should recognize short-term capital gain or loss in respect of the Put Option in an amount equal to the difference between the total Put Option premiums previously received by the U.S. Holder and the Put Option Assumption Payment.

Alternative Tax Treatments. Due to the absence of authorities that directly address the proper tax treatment of the Notes, prospective investors are urged to consult their tax advisors regarding all possible alternative tax treatments of an investment in the Notes. In particular, the IRS could seek to subject the Notes to the Treasury regulations governing contingent payment debt instruments. If the IRS were successful in that regard, the timing and character of income on the Notes would be affected significantly. Among other things, a U.S. Holder would be required to accrue original issue discount every year at a “comparable yield” determined at the time of issuance. In addition, any gain realized by a U.S. Holder at maturity or upon a sale, exchange, or redemption of the Notes generally would be treated as ordinary income, and any loss realized at maturity or upon a sale, exchange, or redemption of the Notes generally would be treated as ordinary loss to the extent of the U.S. Holder’s prior accruals of original issue discount, and as capital loss thereafter. Alternatively, under an alternative characterization of the Notes as income-bearing single financial contracts, the entire Fixed Coupon Payments could be required to be included in income as ordinary income by a U.S. holder at the time received accrued. Other alternative characterizations are possible and prospective investors should consult with their tax advisors regarding all aspects of the U.S. federal income tax consequences of an investment in the Notes.

The IRS released Notice 2008-2 (the “Notice”), which sought comments from the public on the taxation of financial instruments currently taxed as “prepaid forward contracts.” This Notice addresses instruments such as the Notes. According to the Notice, the IRS and Treasury are considering whether a holder of an instrument such as the Notes should be required to accrue ordinary income on a current basis, regardless of whether any payments are made prior to maturity. It is not possible to determine what guidance the IRS and Treasury will ultimately issue, if any. Any such future guidance may affect the amount, timing and character of income, gain, or loss in respect of the Notes, possibly with retroactive effect.

The IRS and Treasury are also considering additional issues, including whether additional gain or loss from such instruments should be treated as ordinary or capital, whether foreign holders of such instruments should be subject to withholding tax on any deemed income accruals, whether Section 1260 of the Code, concerning certain “constructive ownership transactions,” generally applies or should generally apply to such instruments, and whether any of these determinations depend on the nature of the underlying asset.

In addition, proposed Treasury regulations require the accrual of income on a current basis for contingent payments made under certain notional principal contracts. The preamble to the regulations states that the “wait and see” method of accounting does not properly reflect the economic accrual of income on those contracts, and requires current accrual of income for some contracts already in existence. While the proposed regulations do not

apply to prepaid forward contracts, the preamble to the proposed regulations expresses the view that similar timing issues exist in the case of prepaid forward contracts. If the IRS or Treasury publishes future guidance requiring current economic accrual for contingent payments on prepaid forward contracts, it is possible that you could be required to accrue income over the term of the Notes.

Because of the absence of authority regarding the appropriate tax characterization of the Notes, it is also possible that the IRS could seek to characterize the Notes in a manner that results in tax consequences that are different from those described above. For example, the IRS could possibly assert that any gain or loss that a holder may recognize at maturity or upon the sale, exchange, or redemption of the Notes should be treated as ordinary gain or loss.

Non-U.S. Holders

Assuming the treatment of the Notes as set forth above is respected and subject to the discussions below regarding the potential application of Section 871(m) of the Code and the discussions in the accompanying prospectus regarding FATCA, Fixed Coupon Payments with respect to a Note, and gain realized on the sale, exchange or redemption of such Note, should not be subject to U.S. federal income or withholding tax under current law, provided that:

Certification Requirement. The certification requirement referred to in the preceding paragraph will be fulfilled if the beneficial owner of a Note (or a financial institution holding a Note on behalf of the beneficial owner) furnishes to the applicable withholding agent an IRS Form W-8BEN (or other appropriate form), on which the beneficial owner certifies under penalties of perjury that it is not a U.S. person.

Alternative Tax Treatments. As described above under “— U.S. Holders — Alternative Tax Treatments,” the IRS may seek to apply a different characterization and tax treatment from the treatment described herein. While the U.S. federal income and withholding tax consequences to a Non-U.S. Holder of ownership and disposition of a Note under current law should generally be the same as those described immediately above, it is possible that a Non-U.S. Holder could be subject to withholding tax under certain recharacterizations of the Notes.

Moreover, among the issues addressed in the Notice described in “— U.S. Holders — Alternative Tax Treatments” is the degree, if any, to which income realized by Non-U.S. Holders should be subject to withholding tax. It is possible that any Treasury regulations or other guidance issued after consideration of this issue could materially and adversely affect the withholding tax consequences of ownership and disposition of the Notes, possibly with retroactive effect. Accordingly, prospective investors should consult their tax advisors regarding all aspects of the U.S. federal income tax consequences of an investment in the Notes, including the possible implications of the Notice discussed above. Prospective investors should note that we currently do not intend to withhold on any of the payments made with respect to the Notes to Non-U.S. Holders (subject to compliance by such holders with the certification requirement described above and to the discussion regarding FATCA in the accompanying prospectus). However, in the event of a change of law or any formal or informal guidance by the IRS, the Treasury or Congress, we (or the applicable paying agent) may decide to withhold on payments made with respect to the Notes to Non-U.S. Holders and we will not be required to pay any additional amounts with respect to amounts withheld.

Notwithstanding the foregoing, gain from the sale, exchange, or redemption of the Notes or their settlement at maturity may be subject to U.S. federal income tax if that Non-U.S. Holder is a non-resident alien individual and is present in the U.S. for 183 days or more during the taxable year of the sale, exchange, redemption, or settlement and certain other conditions are satisfied.

If a Non-U.S. Holder of the Notes is engaged in the conduct of a trade or business within the U.S. and if any Fixed Coupon Payment and gain realized on the settlement at maturity, or upon sale, exchange, or redemption of the Notes, is effectively connected with the conduct of such trade or business (and, if certain tax treaties apply, is attributable to a permanent establishment maintained by the Non-U.S. Holder in the U.S.), the Non-U.S. Holder, although exempt from U.S. federal withholding tax, generally will be subject to U.S. federal income tax on such Fixed Coupon Payment and gain on a net income basis in the same manner as if it were a U.S. Holder. Such Non-U.S. Holders should read the material under the heading “—U.S. Holders,” for a description of the U.S. federal income tax consequences of acquiring, owning, and disposing of the Notes. In addition, if such Non-U.S. Holder is a foreign corporation, it may also be subject to a branch profits tax equal to 30% (or such lower rate provided by any applicable tax treaty) of a portion of its earnings and profits for the taxable year that are effectively connected with its conduct of a trade or business in the U.S., subject to certain adjustments.

A “dividend equivalent” payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a Non-U.S. Holder. Under Treasury regulations, payments (including deemed payments) with respect to equity-linked instruments (“ELIs”) that are “specified ELIs” may be treated as dividend equivalents if such specified ELIs reference an interest in an “underlying security,” which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, IRS guidance 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. Based on our determination that the Notes are not delta-one instruments, Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the Notes. However, it is possible that the Notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Underlying Stocks or the Notes, and following such occurrence the Notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. Holders that enter, or have entered, into other transactions in respect of the Underlying Stocks or the Notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the Notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

As discussed above, alternative characterizations of the Notes for U.S. federal income tax purposes are possible. Should an alternative characterization, by reason of change or clarification of the law, by regulation or otherwise, cause payments as to the Notes to become subject to withholding tax in addition to the withholding tax described above, tax will be withheld at the applicable statutory rate. Prospective Non-U.S. Holders should consult their own tax advisors regarding the tax consequences of such alternative characterizations.

U.S. Federal Estate Tax. Under current law, while the matter is not entirely clear, individual Non-U.S. Holders, and entities whose property is potentially includible in those individuals’ gross estates for U.S. federal estate tax purposes (for example, a trust funded by such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, a Note is likely to be treated as U.S. situs property, subject to U.S. federal estate tax. These individuals and entities should consult their own tax advisors regarding the U.S. federal estate tax consequences of investing in a Note.

Backup Withholding and Information Reporting

Please see the discussion under “U.S. Federal Income Tax Considerations — General — Backup Withholding and Information Reporting” in the accompanying prospectus for a description of the applicability of the backup withholding and information reporting rules to payments made on the Notes.
