The notes and the related guarantee:

BofA Securities

March , 2026

Summary

The Autocallable Strategic Accelerated Redemption Securities^® Linked to the MSCI Emerging Markets Index, due March , 2029 (the "notes") are our senior unsecured debt securities. Payments on the notes are fully and unconditionally guaranteed by BAC. The notes and the related guarantee are not insured by the Federal Deposit Insurance Corporation or secured by collateral. The notes will rank equally in right of payment with all of BofA Finance's other unsecured and unsubordinated obligations, except obligations that are subject to any priorities or preferences by law, and the related guarantee will rank equally in right of payment with all of BAC's other unsecured and unsubordinated obligations, except obligations that are subject to any priorities or preferences by law, and senior to its subordinated obligations. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of BofA Finance, as issuer, and BAC, as guarantor. The notes will be automatically called if the Observation Value of the Market Measure, which is the MSCI Emerging Markets Index (the "Index"), on any Call Observation Date is equal to or greater than the Call Value. If your notes are called, you will receive the applicable Call Payment on the related Call Payment Date, and no further amounts will be payable on the notes. If your notes are not called, at maturity you will lose a portion, or possibly all, of the principal amount depending on the performance of the Index. 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 and BAC's credit risk. See "Terms of the Notes" below.

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 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 and costs associated with hedging the notes, 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, BAC's and our other affiliates' pricing models, which take into consideration BAC's internal funding rate and the market prices for the hedging arrangements related to the notes. The initial estimated value of the notes calculated on the pricing date will be set forth in the final term sheet made available to investors in the notes. For more information about the initial estimated value and the structuring of the notes, see "Structuring the Notes" on page TS-12.

The terms and risks of the notes are contained in this term sheet and in the following:

Investor Considerations

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

Examples of Hypothetical Payments

The following examples and table 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 Call Payment or the Redemption Amount, as applicable, based on the hypothetical terms set forth below. The actual amount you receive and the resulting return will depend on the actual Starting Value, Call Value and Observation Values of the Index, the actual Call Premiums, whether the notes are automatically called and the term of your investment. The following examples do not take into account any tax consequences from investing in the notes. These examples are based on the following hypothetical terms:

1)a Starting Value of 100.00 for the Index;

2)a Call Value of 100.00 for the Index;

3)an expected term of the notes of approximately three years, if the notes are not called on one of the first two Call Observation Dates;

4)a Call Premium of 14.00% of the principal amount if the notes are called on the first Call Observation Date; 28.00% if called on the second Call Observation Date; and 42.00% if called on the final Call Observation Date (in each case, the midpoint of the applicable Call Premium range); and

5)the Call Observation Dates occurring approximately one, two and three years after the pricing date.

The hypothetical Starting Value of 100.00 for the Index used in these examples has been chosen for illustrative purposes only, and does not represent a likely actual Starting Value of the Index. For recent actual levels of the Index, see "The Index" section below. The Index is a price return index and as such the levels of the Index 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 and guarantor credit risk.

Notes Are Called on a Call Observation Date

The notes will be called at $10.00 plus the applicable Call Premium if the Observation Value of the Index on one of the Call Observation Dates is equal to or greater than the Call Value. After the notes are called, they will no longer remain outstanding and there will not be any further payments on the notes.

Example 1 - The Observation Value of the Index on the first Call Observation Date is 110.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $1.40 = $11.40 per unit.

Example 2 - The Observation Value of the Index on the first Call Observation Date is below the Call Value, but the Observation Value of the Index on the second Call Observation Date is 102.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $2.80 = $12.80 per unit.

Example 3 - The Observation Value of the Index on each of the first two Call Observation Dates is below the Call Value, but the Observation Value of the Index on the third and final Call Observation Date is 110.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $4.20 = $14.20 per unit.

Notes Are Not Called on Any Call Observation Date

Example 4 - The notes are not called on any Call Observation Date. This necessarily means that the Ending Value is less than the Starting Value. The Redemption Amount will be less than the principal amount and could be zero. For example, if the Ending Value of the Index is 50.00, the Redemption Amount per unit will be:

Summary of the Hypothetical Examples

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-4 of the accompanying product supplement, page S-7 of the Series A MTN prospectus supplement, and page 7 of the prospectus identified above. 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. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Structure-related Risks

■There is no fixed principal repayment amount on the notes at maturity. If the notes are not called, you will lose a portion, or possibly all, of the principal amount, depending on the performance of the Market Measure.

■Your investment return is limited to the return represented by the applicable Call Premium and may be less than a comparable investment directly in the stocks included in the Market Measure. If, on a Call Observation Date, the Observation Value is greater than or equal to the Call Value, we will automatically call the notes. If the notes are automatically called, your return will be limited to the applicable Call Premium, regardless of the extent of the increase in the value of the Market Measure.

■Payments on the notes will not reflect changes in the value of the Market Measure other than on the Call Observation Dates. As a result, even if the level of the Market Measure increases during the term of the notes, you will not receive any Call Payment if the Observation Value on each Call Observation Date is less than the Call Value. Similarly, if the notes are not called, you will receive a Redemption Amount that is less than the principal amount if the Ending Value is less than the Starting Value on the Final Calculation Day, even if the level of the Market Measure was greater than the Starting Value prior to such Final Calculation Day.

■If the notes are called, you will be subject to reinvestment risk, and you will lose the opportunity to receive any higher Call Premium that otherwise might have been payable on a later date.

■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 the credit risk of BAC, and any actual or perceived changes in our or BAC's creditworthiness are expected to affect the value of the notes. If we and BAC become insolvent or are unable to pay our respective obligations, you may lose your entire investment.

■We are a finance subsidiary and, as such, have no independent assets, operations or revenues.

■BAC's obligations under its guarantee of the notes will be structurally subordinated to liabilities of its subsidiaries.

■The notes issued by us will not have the benefit of any cross-default or cross-acceleration with other indebtedness of BofA Finance or BAC; events of bankruptcy or insolvency or resolution proceedings relating to BAC and covenant breach by BAC will not constitute an event of default with respect to the notes.

Valuation- and Market-related Risks

■The initial estimated value of the notes considers certain assumptions and variables and relies in part on certain forecasts about future events, which may prove to be incorrect. The initial estimated value of the notes is an estimate only, determined as of a particular point in time by reference to our and our affiliates' pricing models. These pricing models consider certain assumptions and variables, including our credit spreads and those of BAC, BAC's internal funding rate on the pricing date, mid-market terms on hedging transactions, expectations on interest rates and volatility, price-sensitivity analysis, and the expected term of the notes. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect.

■The public offering price you pay for the notes will exceed the initial estimated value. If you attempt to sell the notes prior to maturity, their market value may be lower than the price you paid for them and lower than the initial estimated value. This is due to, among other things, changes in the level of the Index, changes in BAC's internal funding rate, and the inclusion in the public offering price of the underwriting discount and costs associated with hedging the notes, all as further described in "Structuring the Notes" on page TS-12. These factors, together with various credit, market and economic factors over the term of the notes, are expected to reduce the price at which you may be able to sell the notes in any secondary market and will affect the value of the notes in complex and unpredictable ways.

■The initial estimated value does not represent a minimum or maximum price at which we, BAC, MLPF&S, BofAS or any of our other affiliates would be willing to purchase your notes in any secondary market (if any exists) at any time. The value of your notes at any time after issuance will vary based on many factors that cannot be predicted with accuracy, including the performance of the Index, our and BAC's creditworthiness and changes in market conditions.

■A trading market is not expected to develop for the notes. None of us, BAC, 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

■BAC and its affiliates' hedging and trading activities (including trades in shares of companies included in the Index) and any hedging and trading activities BAC or its affiliates engage in that are not for your account or on your behalf, 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 an affiliate of ours. 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 BAC and our other affiliates may from time to time own securities of companies included in the Index, except to the extent that BAC's common stock is included in the Index, we, BAC and our other affiliates do not control any company included in the Index, and have not verified any disclosure made by any other company.

■Your return on the notes and the value of the notes may be affected by exchange rate movements and factors affecting the international securities markets, specifically changes in the countries represented by the Index. In addition, you will not obtain the benefit of any increase in the value of the relevant currencies against the U.S. dollar, which you would have received if you had owned the securities represented by the Index during the term of your notes, although the levels of the Index may be adversely affected by general exchange rate movements in the market.

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 Tax Consequences" below and "U.S. Federal Income Tax Summary" beginning on page PS-48 of the accompanying product supplement.

Additional Risk Factor

There are risks associated with emerging markets.

An investment in the notes will involve risks not generally associated with investments which have no emerging market component. In particular, many emerging nations are undergoing rapid change, involving the restructuring of economic, political, financial and legal systems. Regulatory and tax environments may be subject to change without review or appeal. Many emerging markets suffer from underdevelopment of capital markets and tax regulation. The risk of expropriation and nationalization remains a threat. Guarding against such risks is made more difficult by low levels of corporate disclosure and unreliability of economic and financial data.

The removal of Russian securities from the Index may have a material adverse effect on the notes.

On March 2, 2022, after the conclusion of a consultation on the appropriate treatment of the Russian equity market within its indices, the MSCI Inc. ("MSCI"), the Index sponsor of the MSCI Emerging Markets Index, announced that it would remove Russian securities from the Index, effective after the close on March 9, 2022. We cannot predict the ongoing effects of that removal on the level of the Index. The historical performance of the Index prior to March 9, 2022 reflects the inclusion of Russian securities, while results thereafter do not include Russian securities and may differ materially from how the Index would have performed if Russian securities had not been removed.

Other Terms of the Notes

Market Measure Business Day

The following definition shall supersede and replace the definition of a "Market Measure Business Day" set forth in the accompanying product supplement:

A "Market Measure Business Day" means a day on which:

(A) each of the London Stock Exchange, the Hong Kong Stock Exchange, the São Paulo Stock Exchange, and the Korea Stock Exchange (or any successor to the foregoing exchanges) are open for trading; and

(B) the Index or any successor thereto is calculated and published.

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. The information reflects the policies of, and is subject to change by, MSCI (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 of the accompanying product supplement beginning on page PS-31 entitled "Description of the Notes-Discontinuance of an Index." None of us, BAC, the calculation agent, MLPF&S or BofAS accepts any responsibility for the calculation, maintenance or publication of the Index or any successor index.

The MSCI Emerging Markets Index

The Index is intended to measure equity market performance in the global emerging markets. The Index is a free float-adjusted market capitalization index with a base date of December 31, 1987 and an initial value of 100. The Index is calculated daily in U.S. dollars and published in real time every 60 seconds during market trading hours. The Index consists of the following 24 emerging market country indices: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Kuwait, Malaysia, Mexico, Peru, Philippines, Poland, Qatar, Saudi Arabia, South Africa, Taiwan, Thailand, Turkey and United Arab Emirates. The Index is an "MSCI Index."

The Country Indices

Each country's index included in an MSCI Index is referred to as a "Country Index." Under the MSCI methodology, each Country Index is an "MSCI Global Standard Index." The components of each Country Index used to be selected by the Index sponsor from among the universe of securities eligible for inclusion in the relevant Country Index so as to target an 85% free float-adjusted market representation level within each of a number of industry groups, subject to adjustments to (i) provide for sufficient liquidity, (ii) reflect foreign investment restrictions (only those securities that can be held by non-residents of the country corresponding to the relevant Country Index are included) and (iii) meet certain other investibility criteria. Following a change in the Index sponsor's methodology implemented in May 2008, the 85% target is now measured at the level of the country universe of eligible securities rather than the industry group level-so each Country Index will seek to include the securities that represent 85% of the free float-adjusted market capitalization of all securities eligible for inclusion, but will still be subject to liquidity, foreign investment restrictions and other investibility adjustments. The Index sponsor defines "free float" as total shares excluding shares held by strategic investors such as governments, corporations, controlling shareholders and management, and shares subject to foreign ownership restrictions.

Calculation of the Country Indices

Each Country Index is a free float-adjusted market capitalization index that is designed to measure the market performance, including price performance, of the equity securities in that country. Each Country Index is calculated in the relevant local currency as well as in U.S. dollars, with price, gross and net returns.

Each component is included in the relevant Country Index at a weight that reflects the ratio of its free float-adjusted market capitalization (i.e., free public float multiplied by price) to the free float-adjusted market capitalization of all the components in that Country Index. The Index sponsor defines the free float of a security as the proportion of shares outstanding that is deemed to be available for purchase in the public equity markets by international investors.

Calculation of the MSCI Indices

The performance of a MSCI Index on any given day represents the weighted performance of all of the components included in all of the Country Indices. Each component in a MSCI Index is included at a weight that reflects the ratio of its free float-adjusted market capitalization (i.e., free public float multiplied by price) to the free float-adjusted market capitalization of all the components included in all of the Country Indices.

Maintenance of and Changes to the MSCI Indices

The Index sponsor maintains the MSCI Indices with the objective of reflecting, on a timely basis, the evolution of the underlying equity markets and segments. In maintaining the indices, emphasis is also placed on continuity, continuous investibility of the constituents, replicability, index stability and low turnover in the indices.

As part of the changes to the Index sponsor's methodology which became effective in May 2008, maintenance of the indices falls into three broad categories:

Based on these reviews, additional components may be added, and current components may be removed, at any time. The Index sponsor generally announces all changes resulting from semi-annual reviews, quarterly reviews and ongoing events in advance of their implementation, although in exceptional cases they may be announced during market hours for same or next day implementation.

Neither we, MLPF&S nor BofAS, or any of our respective affiliates, accepts any responsibility for the calculation, maintenance, or publication of, or for any error, omission, or disruption in, the MSCI Indices. The Index sponsor does not guarantee the accuracy or the completeness of the MSCI Indices or any data included in the MSCI Indices. The Index sponsor assumes no liability for any errors, omissions, or disruption in the calculation and dissemination of the MSCI Indices. The Index sponsor disclaims all responsibility for any errors or omissions in the calculation and dissemination of the MSCI Indices or the manner in which the MSCI Indices is applied in determining the amount payable on the notes at maturity.

Prices and Exchange Rates

Prices

The prices used to calculate the MSCI Indices are the official exchange closing prices or those figures accepted as such. The Index sponsor reserves the right to use an alternative pricing source on any given day.

Exchange Rates

The Index sponsor uses the closing spot rates published by WM / Reuters at 4:00 p.m., London time. The Index sponsor uses WM / Reuters rates for all countries for which it provides indices.

In case WM/Reuters does not provide rates for specific markets on given days (for example Christmas Day and New Year's Day), the previous business day's rates are normally used. The Index sponsor independently monitors the exchange rates on all its indices and may, under exceptional circumstances, elect to use an alternative exchange rate if the WM / Reuters rates are not available, or if the Index sponsor determines that the WM / Reuters rates are not reflective of market circumstances for a given currency on a particular day. In such circumstances, an announcement would be sent to clients with the related information. If appropriate, the Index sponsor may conduct a consultation with the investment community to gather feedback on the most relevant exchange rate.

The following graph shows the daily historical performance of the Index in the period from January 1, 2016 through March 4, 2026. 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 March 4, 2026, the closing level of the Index was 1,472.03.

Historical Performance of the Index

This historical data on the Index is not necessarily indicative of the future performance of the Index or what the value of the notes may be. Any historical upward or downward trend in the level of the Index during any period set forth above is not an indication that the level of the Index 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 levels of the Index.

License Agreement

Our affiliate, MLPF&S, has entered into a non-exclusive license agreement with MSCI whereby MLPF&S and certain of its affiliates, in exchange for a fee, are permitted to use the MSCI indices in connection with certain securities, including the notes. We are not affiliated with MSCI; the only relationship between MSCI and us is any licensing of the use of MSCI's indices and trademarks relating to them.

The license agreement provides that the following language must be set forth herein:

THE NOTES ARE NOT SPONSORED, ENDORSED, SOLD, OR PROMOTED BY MSCI, ANY OF ITS AFFILIATES, ANY OF ITS INFORMATION PROVIDERS, OR ANY OTHER THIRD PARTY INVOLVED IN, OR RELATED TO, COMPILING, COMPUTING, OR CREATING THE MXEF INDEX (COLLECTIVELY, THE "MSCI PARTIES"). THE MXEF INDEX IS THE EXCLUSIVE PROPERTY OF

MSCI. MSCI AND THE MXEF INDEX ARE SERVICE MARKS OF MSCI OR ITS AFFILIATES AND HAVE BEEN LICENSED TO US FOR USE FOR CERTAIN PURPOSES. THE NOTES HAVE NOT BEEN PASSED ON BY ANY OF THE MSCI PARTIES AS TO THEIR LEGALITY OR SUITABILITY WITH RESPECT TO ANY PERSON OR ENTITY AND NONE OF THE MSCI PARTIES MAKES ANY WARRANTIES OR BEARS ANY LIABILITY WITH RESPECT TO THE NOTES. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, NONE OF THE MSCI PARTIES MAKES ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, TO US OR OWNERS OF THE NOTES OR ANY OTHER PERSON OR ENTITY REGARDING THE ADVISABILITY OF INVESTING IN ANY SECURITIES GENERALLY OR IN THIS OFFERING PARTICULARLY OR THE ABILITY OF ANY MSCI INDEX TO TRACK CORRESPONDING STOCK MARKET PERFORMANCE. MSCI OR ITS AFFILIATES ARE THE LICENSORS OF CERTAIN TRADEMARKS, SERVICE MARKS, AND TRADE NAMES OF THE MXEF INDEX, WHICH ARE DETERMINED, COMPOSED, AND CALCULATED BY MSCI WITHOUT REGARD TO THE NOTES, TO US, TO THE OWNERS OF THE NOTES, OR TO ANY OTHER PERSON OR ENTITY. NONE OF THE MSCI PARTIES HAS ANY OBLIGATION TO TAKE THE NEEDS OF US OR OWNERS OF THE NOTES OR ANY OTHER PERSON OR ENTITY INTO CONSIDERATION IN DETERMINING, COMPOSING, OR CALCULATING THE MXEF INDEX. NONE OF THE MSCI PARTIES IS RESPONSIBLE FOR OR HAS PARTICIPATED IN THE DETERMINATION OF THE TIMING OF, PRICES AT, OR QUANTITIES OF THE NOTES TO BE ISSUED OR IN THE DETERMINATION OR CALCULATION OF THE AMOUNT THAT MAY BE PAID AT MATURITY ON THE NOTES. NONE OF THE MSCI PARTIES HAS ANY OBLIGATION OR LIABILITY TO US OR TO OWNERS OF THE NOTES OR ANY OTHER PERSON OR ENTITY IN CONNECTION WITH THE ADMINISTRATION, MARKETING OR, OFFERING OF THE NOTES.

No purchaser, seller or holder of the notes, or any other person or entity, should use or refer to any MSCI trade name, trademark or service mark to sponsor, endorse, market or promote the notes without first contacting MSCI to determine whether MSCI's permission is required. Under no circumstances may any person or entity claim any affiliation with MSCI without the prior written permission of MSCI.

Supplement to the Plan of Distribution; Conflicts of Interest

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 purchase the notes from BofAS for resale, and will receive a selling concession in connection with the sale of the notes in an amount up to the full amount of underwriting discount set forth on the cover of this term sheet.

We will pay a fee to LFT Securities, LLC for providing certain electronic platform services with respect to this offering, which will reduce the economic terms of the notes to you. An affiliate of BofAS has an ownership interest in LFT Securities, LLC.

MLPF&S and BofAS, each a broker-dealer subsidiary of BAC, are members of the Financial Industry Regulatory Authority, Inc. ("FINRA") and will participate as selling agent in the case of BofAS, and as dealer, in the case of MLPF&S, in the distribution of the notes. Accordingly, offerings of the notes will conform to the requirements of Rule 5121 applicable to FINRA members. MLPF&S may not make sales in this offering to any of its discretionary accounts without the prior written approval of the account holder.

We may deliver the notes against payment therefor in New York, New York on a date that is greater than one business day 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 one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement of the notes occurs more than one business day from the pricing date, purchasers who wish to trade the notes more than one business day 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 10,000 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 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, neither we nor any of our affiliates is obligated to purchase your notes at any price, or at any time, and we cannot assure you that we or any of our 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 our 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.

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Index. The related guarantees are BAC's obligations. 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 that is more favorable to BAC than the rate that it might pay for a conventional fixed or floating rate debt security. This rate, which we refer to in this term sheet as BAC's internal funding rate, is typically lower than the rate BAC would pay when it issues conventional fixed or floating rate debt securities. 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, if not previously called, 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 our other affiliates. The terms of these hedging arrangements are determined by seeking bids from market participants, including MLPF&S, 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 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. These hedging arrangements are expected to result in a profit to those engaging in the hedging activity, which could be more or less than initially expected, but could also result in a loss.

Summary 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.

■You agree with us (in the absence of an administrative determination, or judicial ruling to the contrary) to characterize and treat the notes for all tax purposes as a callable single financial contract with respect to the Index.

■Under this characterization and tax treatment of the notes, a U.S. Holder (as defined in the prospectus) generally will recognize capital gain or loss upon maturity or upon a sale, exchange or redemption of the notes prior to maturity. This capital gain or loss generally will be long-term capital gain or loss if you held the notes for more than one year.

■No assurance can be given that the Internal Revenue Service ("IRS") or any court will agree with this characterization and tax treatment.

■Under current IRS guidance, withholding on "dividend equivalent" payments (as discussed in the product supplement), if any, will not apply to notes that are issued as of the date of this term sheet unless such notes are "delta-one" instruments.

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-48 of the accompanying product supplement.
