	BofA Finance LLC Medium-Term Notes, Series A *Fully and Unconditionally Guaranteed by Bank of America Corporation*
	Market Linked Securities—Auto-Callable with Contingent Downside Principal at Risk Securities Linked to the Lowest Performing of the Nasdaq-100^® Index, the SPDR^® S&P^® Biotech ETF and the SPDR^® S&P^® Oil & Gas Exploration & Production ETF due September 24, 2029
■ Linked to the Lowest Performing of the Nasdaq-100^® Index, the SPDR^® S&P^® Biotech ETF and the SPDR^® S&P^® Oil & Gas Exploration & Production ETF (each referred to as an “Underlying”) ■ Unlike ordinary debt securities, the Securities do not pay interest, do not repay a fixed amount of principal at maturity and are subject to potential automatic call upon the terms described below. Whether the Securities are automatically called for a fixed call premium or, if not automatically called, the maturity payment amount, will depend, in each case, on the closing value of the Lowest Performing Underlying on the relevant Call Date. The Lowest Performing Underlying on any Call Date is the Underlying that has the lowest closing value on that Call Date as a percentage of its Starting Value ■ Automatic Call. If the closing value of the Lowest Performing Underlying on any Call Date is greater than or equal to its Call Value, the Securities will be automatically called for the principal amount plus the Call Premium applicable to that Call Date. The Call Premium applicable to each Call Date will be a percentage of the principal amount that increases for each Call Date based on a simple (non-compounding) return of at least approximately 12.00% per annum (to be determined on the Pricing Date). The Call Value for each Underlying is 86% of its Starting Value. Please see "Terms of the Securities – Call Dates and Call Premiums" below for the Call Dates and Call Premiums ■ Maturity Payment Amount. If the Securities are not automatically called, you will receive a Maturity Payment Amount that could be equal to or less than the principal amount per Security depending on the closing value of the Lowest Performing Underlying on the Final Calculation Day as follows: ■ If the closing value of the Lowest Performing Underlying on the Final Calculation Day is less than its Call Value, but greater than or equal to its Threshold Value, you will receive the principal amount of your Securities ■ If the closing value of the Lowest Performing Underlying on the Final Calculation Day is less than its Threshold Value, you will have full downside exposure to the decrease in the value of the Lowest Performing Underlying from its Starting Value, and you will lose more than 40%, and possibly all, of the principal amount of your Securities. ■ The Threshold Value for each Underlying is 60% of its Starting Value ■ Investors may lose a significant portion, or all, of the principal amount ■ Your return on the Securities will depend solely on the performance of the Underlying that is the Lowest Performing Underlying on each Call Date. You will not benefit in any way from the performance of the better performing Underlyings. Therefore, you will be adversely affected if any Underlying performs poorly, even if the other Underlyings perform favorably ■ Any positive return on the Securities will be limited to the applicable Call Premium, even if the closing value of the Lowest Performing Underlying on the applicable Call Date significantly exceeds its Starting Value. You will not participate in any appreciation of any Underlying beyond the applicable fixed Call Premium ■ All payments on the Securities are subject to the credit risk of BofA Finance LLC (“BofA Finance”), as issuer of the Securities, and Bank of America Corporation (“BAC” or the “Guarantor”), as guarantor of the Securities ■ Securities will not be listed on any securities exchange

The initial estimated value of the Securities as of the Pricing Date is expected to be between $904.25 and $964.25 per Security, which is less than the public offering price listed below. The actual value of your Securities at any time will reflect many factors and cannot be predicted with accuracy. See “Selected Risk Considerations” beginning on page PS-10 of this pricing supplement and “Structuring the Securities” on page PS-32 of this pricing supplement for additional information.

The Securities have complex features and investing in the Securities involves risks not associated with an investment in conventional debt securities. Potential purchasers of the Securities should consider the information in “Selected Risk Considerations” beginning on page PS-10 herein and “Risk Factors” 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.

In addition, the Maturity Date will be postponed if the Final Calculation Day is postponed and will be adjusted for non-business days. For more information regarding adjustments to the Call Dates and the Maturity Date, see “General Terms of the Securities—Consequences of a Market Disruption Event; Postponement of a Calculation Day—Securities Linked to Multiple Market Measures” and “—Payment Dates” in the accompanying product supplement. For purposes of the accompanying product supplement, each Call Date (including the Final Calculation Day) is a “calculation day” and each Call Settlement Date (including the Maturity Date) is a “payment date.” In addition, for information regarding the circumstances that may result in a market disruption event, see “General Terms of the Securities—Certain Terms for Securities Linked to an Index—Market Disruption Events” and “—Certain Terms for Securities Linked to a Fund —Market Disruption Events” in the accompanying product supplement.

Calculation Agent:

BofA Securities, Inc. (“BofAS”), an affiliate of BofA Finance.

Selling Agents:

BofAS and Wells Fargo Securities, LLC (“WFS”).

Under our distribution agreement with BofAS, BofAS will purchase the Securities from us as principal at the public offering price indicated on the cover of this pricing supplement, less the indicated underwriting discount. BofAS will sell the Securities to WFS at the public offering price of the Securities less a concession of up to $25.75 per Security. WFS may provide dealers, which may include Wells Fargo Advisors (“WFA”) (the trade name of the retail brokerage business of WFS’s affiliates, Wells Fargo Clearing Services, LLC and Wells Fargo Advisors Financial Network, LLC), with a selling concession of up to $20.00 per Security. In addition to the concession allowed to

PS-4

Market Linked Securities—Auto-Callable with Contingent Downside

WFA, WFS may pay up to $0.75 per Security to WFA as a distribution expense fee for each Security sold by WFA.

In addition, in respect of certain Securities sold in this offering, BofAS or its affiliates may pay a fee of up to $3.00 per Security to selected securities dealers in consideration for marketing and other services in connection with the distribution of the Securities to other securities dealers.

WFS has advised us that if it, WFA or any of their affiliates makes a secondary market in the Securities at any time up to the Issue Date or during the four-month period following the Issue Date, the secondary market price offered by it, WFA or any of their affiliates will be increased by an amount reflecting a portion of the costs associated with selling, structuring and hedging the Securities that are included in the public offering price of the Securities. Because this portion of the costs is not fully deducted upon issuance, WFS has advised us that any secondary market price it, WFA or any of their affiliates offers during this period will be higher than it otherwise would be outside of this period, as any secondary market price offered outside of this period will reflect the full deduction of the costs as described above. WFS has advised us that the amount of this increase in the secondary market price will decline steadily to zero over this four-month period. If you hold the Securities through an account at WFS, WFA or any of their affiliates, WFS has advised us that it expects that this increase will also be reflected in the value indicated for the Securities on your brokerage account statement. If you hold your Securities through an account at a broker-dealer other than WFS, WFA or any of their affiliates, the value of the Securities on your brokerage account statement may be different than if you held your Securities at WFS, WFA or any of their affiliates.

Events of Default and Acceleration:

If an Event of Default, as defined in the senior indenture relating to the Securities and in the section entitled “Description of Debt Securities of BofA Finance LLC—Events of Default and Rights of Acceleration; Covenant Breaches” on page 54 of the accompanying prospectus, with respect to the Securities occurs and is continuing, the amount payable to a holder of the Securities upon any acceleration permitted under the senior indenture will be equal to the amount described under the caption “Terms of the Securities—Maturity Payment Amount” above, calculated as though the date of acceleration were the Final Calculation Day of the Securities; provided that if the closing value of the Lowest Performing Underlying on the date of acceleration is equal to or greater than its Call Value, then the Maturity Payment Amount will be calculated using a call premium that is prorated to the date of acceleration. In case of a default in the payment of the Securities, whether at their maturity or upon acceleration, the Securities will not bear a default interest rate.

Material Tax Consequences:

For a discussion of the material U.S. federal income and estate tax consequences of the ownership and disposition of the Securities, see “U.S. Federal Income Tax Summary.”

Investor Considerations

The Securities are not appropriate for all investors. The Securities may be an appropriate investment for investors who:

■ believe that the closing value of the Lowest Performing Underlying will be greater than or equal to its Call Value on one of the Call Dates;

■ seek the potential for a fixed return if the Lowest Performing Underlying has appreciated or depreciated by not more than 14% as of any of the Call Dates in lieu of full participation in any potential appreciation of any or all of the Underlyings;

■ are willing to accept the risk that, if the closing value of the Lowest Performing Underlying is less than its Call Value on each Call Date, they will not receive any positive return on their investment in the Securities;

■ are willing to accept the risk that, if the Securities are not automatically called and the Ending Value of the Lowest Performing Underlying on the Final Calculation Day is less than its Threshold Value, they will be fully exposed to the decline in the Lowest Performing Underlying from its Starting Value and will lose more than 40%, and possibly all, of the principal amount of their Securities at maturity;

■ understand that the term of the Securities may be as short as approximately one year and that they will not receive a higher Call Premium payable with respect to a later Call Date if the Securities are called on an earlier Call Date;

■ understand that the return on the Securities will depend solely on the performance of the Underlying that is the Lowest Performing Underlying on each Call Date and that they will not benefit in any way from the performance of the better performing Underlyings;

■ understand that the Securities are riskier than alternative investments linked to only one of the Underlyings or linked to a basket composed of each Underlying;

■ understand and are willing to accept the full downside risks of each Underlying;

■ are willing to forgo interest payments on the Securities and dividends on the Funds or the securities held by or included in the Underlyings, as applicable; and

■ are willing to hold the Securities until maturity.

The Securities may not be an appropriate investment for investors who:

■ seek a liquid investment or are unable or unwilling to hold the Securities to maturity;

■ require full payment of the principal amount of the Securities at maturity;

■ believe that the closing value of the Lowest Performing Underlying will be less than its Call Value on each Call Date;

■ seek a security with a fixed term;

■ are unwilling to accept the risk that, if the closing value of the Lowest Performing Underlying is less than its Call Value on each Call Date, they will not receive any positive return on their investment in the Securities;

■ are unwilling to accept the risk that the closing value of the Lowest Performing Underlying on the Final Calculation Day may decline by more than 40% from its Starting Value to its Ending Value;

■ are unwilling to purchase securities with an estimated value as of the Pricing Date that is lower than the public offering price and that may be as low as the lower estimated value set forth on the cover page;

■ seek current income;

■ are unwilling to accept the risk of exposure to the Underlyings;

■ seek exposure to a basket composed of each Underlying or a similar investment in which the overall return is based on a blend of the performances of the Underlyings, rather than solely on the Lowest Performing Underlying;

■ seek exposure to the upside performance of any or each Underlying beyond the applicable Call Premiums;

■ are unwilling to accept the credit risk of BofA Finance, as issuer, and BAC, as guarantor, to obtain exposure to the Underlyings generally, or to obtain exposure to the Underlyings that the Securities provide specifically; or

■ prefer the lower risk of conventional fixed income investments with comparable maturities issued by companies with comparable credit ratings.

The considerations identified above are not exhaustive. Whether or not the Securities are an appropriate investment for you will depend on your individual circumstances, and you should reach an investment decision only after you and your investment, legal, tax, accounting and other advisors have carefully considered the appropriateness of an investment in the Securities in light of your particular circumstances. You should also review carefully “Selected Risk Considerations” herein and “Risk Factors” in each of the accompanying product supplement, prospectus supplement and prospectus for risks related to an investment in the Securities.

Determining Timing and Amount of Payment on the Securities

The timing and amount of the payment you will receive will be determined as follows:

PS-9

Market Linked Securities—Auto-Callable with Contingent Downside

Selected Risk Considerations

The Securities have complex features and investing in the Securities will involve risks not associated with an investment in conventional debt securities. Your decision to purchase the Securities should be made only after carefully considering the risks of an investment in the Securities, including those discussed below, with your advisors in light of your particular circumstances. The Securities are not an appropriate investment for you if you are not knowledgeable about significant elements of the Securities or financial matters in general. You should carefully review the more detailed explanation of risks relating to the Securities 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.

Structure-related Risks

Your investment may result in a loss; there is no guaranteed return of principal. There is no fixed principal repayment amount on the Securities at maturity. If the Securities are not automatically called and the Ending Value of the Lowest Performing Underlying is less than its Threshold Value, at maturity, you will lose 1% of the principal amount for each 1% that the Ending Value of the Lowest Performing Underlying is less than its Starting Value. In that case, you will lose a significant portion or all of your investment in the Securities.

Any positive investment return on the Securities is limited. You will not participate in any increase in the values of the Underlyings. Any positive investment return is limited to the applicable Call Premium, if any, regardless of the extent to which the closing value of any Underlying on any Call Date exceeds its Call Value. In contrast, a direct investment in a Fund or in the securities held by or included in the Underlyings, as applicable, would allow you to receive the benefit of any appreciation in their values. Thus, any return on the Securities will not reflect the return you would realize if you actually owned those securities and received the dividends paid or distributions made on them. The return on the Securities may be less than a comparable investment directly in the Funds or in the securities included in or held by the Underlyings, as applicable. There is no guarantee that the Securities will be called for more than the principal amount, and it is possible you will not receive any positive return on the Securities.

The Securities do not bear interest. Unlike a conventional debt security, no interest payments will be paid over the term of the Securities, regardless of the extent to which the closing value of any Underlying exceeds its Starting Value, Call Value or Threshold Value on any Call Date.

The amount payable upon an automatic call or the Maturity Payment Amount, as applicable, will not reflect the values of the Underlyings other than on the Call Dates. The values of the Underlyings during the term of the Securities other than on the Call Dates will not affect payments on the Securities. Notwithstanding the foregoing, investors should generally be aware of the performance of the Underlyings while holding the Securities, as the performance of the Underlyings may influence the market value of the Securities. The calculation agent will determine whether the Securities will be automatically called, and will calculate the amount payable upon an automatic call or the Maturity Payment Amount, as applicable, by comparing only the Call Value or Threshold Value, as applicable, to the closing value of the Lowest Performing Underlying on the applicable Call Date. No other values of the Underlyings will be taken into account. As a result, if the Securities are not automatically called, and the Ending Value of the Lowest Performing Underlying is less than its Threshold Value, you will receive less than the principal amount at maturity even if the value of each Underlying was always above its Threshold Value prior to the Final Calculation Day.

The Securities are subject to a potential automatic call, which would limit your ability to receive further payment on the Securities. The Securities are subject to a potential automatic call. The Securities will be automatically called if, on any Call Date, the closing value of the Lowest Performing Underlying is greater than or equal to its Call Value. If the Securities are automatically called, you will be entitled to receive the principal amount and the applicable Call Premium with respect to the applicable Call Date, and no further amounts will be payable with respect to the Securities. In this case, you will lose the opportunity to receive payment of any higher Call Premium that otherwise would be payable after the date of the automatic call. If the Securities are called, you may be unable to invest in other securities with a similar level of risk that could provide a return that is similar to the Securities.

Because the Securities are linked to the lowest performing (and not the average performance) of the Underlyings, you may not receive any return on the Securities and may lose a significant portion or all of your principal amount even if the closing value of one Underlying is always greater than or equal to its Call Value or Threshold Value. Your Securities are linked to the lowest performing of the Underlyings, and a change in the value of one Underlying may not correlate with changes in the value of the other Underlying(s). The Securities are not linked to a basket composed of the Underlyings, where the depreciation in the value of one Underlying could be offset to some extent by the appreciation in the value of the other Underlying(s). In the case of the Securities, the individual performance of each Underlying would not be combined, and the depreciation in the value of one Underlying would not be offset by any appreciation in the value of the other Underlying(s). Even if the closing value of an Underlying is at or above its Call Value on a Call Date, the Securities will not be automatically called, and you will not receive the Call Premium with respect to that Call Date, if the closing value of another Underlying is below its Call Value on that day. In addition, even if the Ending Value of an Underlying is at or above its Threshold Value, you will lose a significant portion or all of your principal if the Ending Value of the Lowest Performing Underlying is below its Threshold Value.

Market Linked Securities—Auto-Callable with Contingent Downside

Your return on the Securities may be less than the yield on a conventional debt security of comparable maturity. Any return that you receive on the Securities may be less than the return you would earn if you purchased a conventional debt security with the same Maturity Date. As a result, your investment in the Securities may not reflect the full opportunity cost to you when you consider factors, such as inflation, that affect the time value of money.

A Call Settlement Date and the Maturity Date may be postponed if a Call Date is postponed. A Call Date (including the Final Calculation Day) with respect to an Underlying will be postponed if the applicable originally scheduled Call Date is not a trading day with respect to any Underlying or if the calculation agent determines that a market disruption event has occurred or is continuing with respect to that Underlying on that Call Date. If such a postponement occurs with respect to an Call Date other than the Final Calculation Day, then the related Call Settlement Date will be postponed. If such a postponement occurs with respect to the Final Calculation Day, the Maturity Date will be the later of (i) the initial Maturity Date and (ii) three business days after the last Final Calculation Day as postponed.

Any payment on the Securities is subject to our credit risk and the credit risk of the Guarantor, and actual or perceived changes in our or the Guarantor’s creditworthiness are expected to affect the value of the Securities. The Securities are our senior unsecured debt securities. Any payment on the Securities will be fully and unconditionally guaranteed by the Guarantor. The Securities are not guaranteed by any entity other than the Guarantor. As a result, your receipt of the payment on an automatic call or the Maturity Payment Amount at maturity will be dependent upon our ability and the ability of the Guarantor to repay our respective obligations under the Securities on the applicable payment date, regardless of the closing value of the Lowest Performing Underlying as compared to its Call Value or Threshold Value, as applicable. No assurance can be given as to what our financial condition or the financial condition of the Guarantor will be at any time after the Pricing Date of the Securities. If we and 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 Securities.

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 of your Securities may adversely affect the market value of the Securities. However, because your return on the Securities depends upon factors in addition to our ability and the ability of the Guarantor to pay our respective obligations, such as the values of the Underlyings, an improvement in our or the Guarantor’s credit ratings will not reduce the other investment risks related to the Securities.

We are a finance subsidiary and, as such, have no independent assets, operations or revenues. We are a finance subsidiary of the Guarantor, have no operations other than those related to the issuance, administration and repayment of our debt securities that are guaranteed by the Guarantor, and are dependent upon the Guarantor and/or its other subsidiaries to meet our obligations under the Securities in the ordinary course. Therefore, our ability to make payments on the Securities may be limited.

Valuation- and Market-related Risks

The public offering price you pay for the Securities will exceed their initial estimated value. The range of initial estimated values of the Securities that is provided on the cover page of this preliminary pricing supplement, and the initial estimated value as of the Pricing Date that will be provided in the final pricing supplement, are each estimates 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 the Guarantor, the Guarantor’s internal funding rate, mid-market terms on hedging transactions, expectations on interest rates, dividends and volatility, price-sensitivity analysis, and the expected term of the Securities. These pricing models rely in part on certain forecasts about future events, which may prove to be incorrect. If you attempt to sell the Securities prior to maturity, their market value may be lower than the price you paid for them and lower than their initial estimated value. This is due to, among other things, changes in the values of the Underlyings, changes in the Guarantor’s internal funding rate, and the inclusion in the public offering price of the underwriting discount and the hedging related charges, all as further described in "Structuring the Securities" below. These factors, together with various credit, market and economic factors over the term of the Securities, are expected to reduce the price at which you may be able to sell the Securities in any secondary market and will affect the value of the Securities in complex and unpredictable ways.

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

We cannot assure you that a trading market for your Securities will ever develop or be maintained. We will not list the Securities on any securities exchange. We cannot predict how the Securities will trade in any secondary market or whether that market will be liquid or illiquid.

PS-11

Market Linked Securities—Auto-Callable with Contingent Downside

The Securities are not designed to be short-term trading instruments, and if you attempt to sell the Securities prior to maturity, their market value, if any, will be affected by various factors that interrelate in complex ways, and their market value may be less than the principal amount. The following factors are expected to affect the value of the Securities: values of the Underlyings at such time; volatility of the Underlyings; economic and other conditions generally; interest rates; dividend yields; exchange rate movements and volatility; our and the Guarantor’s financial condition and creditworthiness; and time to maturity.

Conflict-related Risks

Trading and hedging activities by us, the Guarantor and any of our other affiliates, including BofAS, and WFS and its affiliates, may create conflicts of interest with you and may affect your return on the Securities and their market value. We, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may buy or sell shares of the Funds or the securities held by or included in any of the Underlyings, as applicable, or futures or options contracts on the Underlyings or those securities, or other listed or over-the-counter derivative instruments linked to the Underlyings or those securities. While we, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may from time to time own shares of the Funds or the securities held by or included in the Underlyings, as applicable, except to the extent that BAC’s or Wells Fargo & Company’s (the parent company of WFS) common stock may be included in the Underlyings, as applicable, we, the Guarantor and our other affiliates, including BofAS, and WFS and its affiliates, do not control any company included in the Underlyings, and have not verified any disclosure made by any other company. We, the Guarantor or one or more of our other affiliates, including BofAS, or WFS and its affiliates, may execute such purchases or sales for our own or their own accounts, for business reasons, or in connection with hedging our obligations under the Securities. These transactions may present a conflict of interest between your interest in the Securities and the interests we, the Guarantor and our other affiliates, including BofAS, and WFS and its affiliates, may have in our or their proprietary accounts, in facilitating transactions, including block trades, for our or their other customers, and in accounts under our or their management. These transactions may adversely affect the values of the Underlyings in a manner that could be adverse to your investment in the Securities. On or before the Pricing Date, any purchases or sales by us, the Guarantor or our other affiliates, including BofAS or others on its behalf, and WFS and its affiliates (including for the purpose of hedging some or all of our anticipated exposure in connection with the Securities), may affect the values of the Underlyings. Consequently, the values of the Underlyings may change subsequent to the Pricing Date, which may adversely affect the market value of the Securities.

We, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, also expect to engage in hedging activities that could affect the values of the Underlyings on the Pricing Date. In addition, these hedging activities, including the unwinding of a hedge, may decrease the market value of your Securities prior to maturity, and may affect the amounts to be paid on the Securities. We, the Guarantor or one or more of our other affiliates, including BofAS, and WFS and its affiliates, may purchase or otherwise acquire a long or short position in the Securities and may hold or resell the Securities. For example, BofAS may enter into these transactions in connection with any market making activities in which it engages. We cannot assure you that these activities will not adversely affect the values of the Underlyings, the market value of your Securities prior to maturity or the amounts payable on the Securities.

If WFS, BofAS or an affiliate of either selling agent participating as a dealer in the distribution of the Securities conducts hedging activities for us in connection with the Securities, such selling agent or participating dealer will expect to realize a projected profit from such hedging activities, and this projected profit will be in addition to any discount, concession or fee received in connection with the sale of the Securities to you. This additional projected profit may create a further incentive for the selling agents or participating dealers to sell the Securities to 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. One of our affiliates will be the calculation agent for the Securities and, as such, will make a variety of determinations relating to the Securities, including the amounts that will be paid on the Securities. Under some circumstances, these duties could result in a conflict of interest between its status as our affiliate and its responsibilities as calculation agent.

Underlying-related Risks

Any payments on the Securities and whether the Securities are automatically called will depend upon the performance of the Underlyings, and therefore the Securities are subject to the following risks, each as discussed in more detail in the accompanying product supplement.

●	Changes that affect the Index may adversely affect the value of the Securities and any payments on the Securities.

●	We cannot control actions by any of the unaffiliated companies whose securities are included in the Index.

●	We and our affiliates have no affiliation with the index sponsor and have not independently verified its public disclosure of information.

PS-12

Market Linked Securities—Auto-Callable with Contingent Downside

●	Risks associated with a fund underlying index, or the underlying assets of a Fund, will affect the value of that Fund and hence the value of the Securities.

●	Changes that affect a Fund or its fund underlying index may adversely affect the value of the Securities and any payments on the Securities.

●	We cannot control actions by any of the unaffiliated companies whose securities are held by or included in a Fund or its fund underlying index.

●	We and our affiliates have no affiliation with any fund sponsor or fund underlying index sponsor and have not independently verified their public disclosure of information.

●	There are risks associated with funds.

The Securities are subject to risks associated with foreign securities markets. The NDX includes certain foreign equity securities. You should be aware that investments in securities linked to the value of foreign equity securities involve particular risks. The foreign securities markets comprising the NDX may have less liquidity and may be more volatile than U.S. or other securities markets and market developments may affect foreign markets differently from U.S. or other securities markets. Direct or indirect government intervention to stabilize these foreign securities markets, as well as cross-shareholdings in foreign companies, may affect trading prices and volumes in these markets. Also, there is generally less publicly available information about foreign companies than about those U.S. companies that are subject to the reporting requirements of the SEC, and foreign companies are subject to accounting, auditing and financial reporting standards and requirements that differ from those applicable to U.S. reporting companies. Prices of securities in foreign countries are subject to political, economic, financial and social factors that apply in those geographical regions. These factors, which could negatively affect those securities markets, include the possibility of recent or future changes in a foreign government’s economic and fiscal policies, the possible imposition of, or changes in, currency exchange laws or other laws or restrictions applicable to foreign companies or investments in foreign equity securities and the possibility of fluctuations in the rate of exchange between currencies, the possibility of outbreaks of hostility and political instability and the possibility of natural disaster or adverse public health developments in the region. Moreover, foreign economies may differ favorably or unfavorably from the U.S. economy in important respects such as growth of gross national product, rate of inflation, capital reinvestment, resources and self-sufficiency.

Adverse conditions in the biotechnology sector may reduce your return on the Securities. All of the stocks held by the XBI are issued by companies whose primary lines of business are directly associated with the biotechnology sector. The profitability of these companies is largely dependent on, among other things, demand for the companies’ products, regulatory influences on the biotechnology market (including healthcare reform and receipt of regulatory approvals and compliance with complex regulatory requirements), pricing and reimbursement from third party payors, continued innovation and successful development of new products, talent attraction and retention, maintaining intellectual property rights and industry competition. Any adverse developments affecting the biotechnology sector could adversely affect the price of the XBI and, in turn, the value of the Securities.

The stocks of companies in the oil and gas sector are subject to swift price fluctuations. The issuers of the stocks held by the XOP develop and produce, among other things, crude oil and natural gas, and provide, among other things, drilling services and other services related to oil and gas production and distribution. Stock prices for these types of companies are affected by supply and demand both for their specific product or service and for oil and gas products in general. The price of oil and gas, exploration and production spending, government regulation, world events and economic conditions will likewise affect the performance of these companies. Correspondingly, the stocks of companies in this sector are subject to swift price fluctuations caused by events relating to international politics, energy conservation, the success of exploration projects and tax and other governmental regulatory policies. Weak demand for the companies’ products or services or for oil and gas products and services in general, as well as negative developments in these other areas, would adversely impact the value of the stocks held by the XOP, the market price of the XOP, and the value of the Securities.

The stocks held by the XOP are concentrated in one sector. The XOP holds securities issued by companies in the oil and gas exploration industry. As a result, some of the stocks that will determine the performance of the Securities are concentrated in one sector. Although an investment in the Securities will not give holders any ownership or other direct interests in the securities held by the XOP, the return on an investment in the Securities will be subject to certain risks associated with a direct equity investment in companies in this sector. Accordingly, by investing in the Securities, you will not benefit from the diversification which could result from an investment linked to companies that operate in multiple sectors.

The stocks held by the XBI are concentrated in one sector. The XBI holds securities issued by companies in the biotechnology sector. As a result, some of the stocks that will determine the performance of the Securities are concentrated in one sector. Although an investment in the Securities will not give holders any ownership or other direct interests in the securities held by the XBI, the return on an investment in the Securities will be subject to certain risks associated with a direct equity investment in companies in this sector.

85.00%	$1,000.00	0.00%

0.00%	$0.00	-100.00%

⁽¹⁾ The Performance Factor of the Lowest Performing Underlying on the Final Calculation Day is equal to its Ending Value divided by its Starting Value (expressed as a percentage).

Hypothetical Examples Of Payment Upon An Automatic Call Or At Maturity

Example 1. The closing value of the Lowest Performing Underlying on the first Call Date is greater than its Call Value, and the Securities are automatically called on the first Call Date:

	Nasdaq-100^® Index		SPDR^® S&P^® Biotech ETF	SPDR^® S&P^® Oil & Gas Exploration & Production ETF
Hypothetical Starting Value:		100.00	$100.00	$100.00
Hypothetical Call Value:		86.00	$86.00	$86.00
Hypothetical closing value on first Call Date:		140.00	$135.00	$130.00
Performance Factor on first Call Date (closing value on first Call Date *divided by* Starting Value):		140.00%	135.00%	130.00%

Step 1: Determine which Underlying is the Lowest Performing Underlying on the first Call Date.

In this example, the SPDR^® S&P^® Oil & Gas Exploration & Production ETF has the lowest Performance Factor on the first Call Date and is, therefore, the Lowest Performing Underlying on the first Call Date.

Step 2: Determine the payment upon automatic call.

Because the hypothetical closing value of the Lowest Performing Underlying on the first Call Date is greater than its hypothetical Call Value, the Securities are automatically called on the first Call Date and you will receive on the related Call Settlement Date the principal amount of your Securities plus a Call Premium of 12.00% of the principal amount. Even though the Lowest Performing Underlying on the first Call Date appreciated by 30.00% from its Starting Value to its closing value on the first Call Date in this example, your return is limited to the Call Premium of 12.00% that is applicable to such Call Date.

On the Call Settlement Date, you would receive $1,120.00 per Security.

Example 2. The Securities are not automatically called prior to the last Call Date (the Final Calculation Day). The closing value of the Lowest Performing Underlying on the Final Calculation Day is greater than its Call Value, and the Securities are automatically called on the Final Calculation Day:

	Nasdaq-100^® Index	SPDR^® S&P^® Biotech ETF	SPDR^® S&P^® Oil & Gas Exploration & Production ETF
Hypothetical Starting Value:	100.00	$100.00	$100.00
Hypothetical Call Value:	86.00	$86.00	$86.00
Hypothetical closing values on Call Dates prior to the Final Calculation Day:	Various (all below Call Value)	Various (all above Call Value)	Various (all below Call Value)
Hypothetical closing value on Final Calculation Day (i.e., the Ending Value):	110.00	107.00	99.00

Market Linked Securities—Auto-Callable with Contingent Downside

	Nasdaq-100^® Index	SPDR^® S&P^® Biotech ETF	SPDR^® S&P^® Oil & Gas Exploration & Production ETF
Performance Factor on Final Calculation Day (Ending Value *divided by* Starting Value):	110.00%	107.00%	99.00%

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Final Calculation Day.

In this example, the SPDR^® S&P^® Oil & Gas Exploration & Production ETF has the lowest Performance Factor on the Final Calculation Day and is, therefore, the Lowest Performing Underlying on the Final Calculation Day.

Step 2: Determine the payment upon automatic call.

Because the hypothetical closing value of the Lowest Performing Underlying on each Call Date prior to the last Call Date (which is the Final Calculation Day) is less than its hypothetical Call Value, the Securities are not called prior to the Final Calculation Day. Because the hypothetical closing value of the Lowest Performing Underlying on the Final Calculation Day is greater than its hypothetical Call Value, the Securities are automatically called on the Final Calculation Day and you will receive on the related Call Settlement Date (which is the Maturity Date) the principal amount of your Securities plus a Call Premium of 48.00% of the principal amount.

On the Call Settlement Date (which is the Maturity Date), you would receive $1,480.00 per Security.

Example 3. The Securities are not automatically called. The Ending Value of the Lowest Performing Underlying on the Final Calculation Day is less than its Call Value but greater than its Threshold Value and the Maturity Payment Amount is equal to the principal amount:

	Nasdaq-100^® Index	SPDR^® S&P^® Biotech ETF	SPDR^® S&P^® Oil & Gas Exploration & Production ETF
Hypothetical Starting Value:	100.00	$100.00	$100.00
Hypothetical Call Value:	86.00	$86.00	$86.00
Hypothetical closing values on Call Dates prior to the Final Calculation Day:	Various (all below Call Value)	Various (all below Call Value)	Various (all below Call Value)
Hypothetical Ending Value:	115.00	$110.00	$85.00
Hypothetical Threshold Value:	60.00	$60.00	$60.00
Performance Factor on Final Calculation Day (Ending Value *divided by* Starting Value):	115.00%	110.00%	85.00%

Step 1: Determine which Underlying is the Lowest Performing Underlying on the Final Calculation Day.

In this example, the SPDR^® S&P^® Oil & Gas Exploration & Production ETF has the lowest Performance Factor and is, therefore, the Lowest Performing Underlying on the Final Calculation Day.

Step 2: Determine the Maturity Payment Amount based on the Ending Value of the Lowest Performing Underlying on the Final Calculation Day.

Because the hypothetical closing value of the Lowest Performing Underlying on each Call Date (including the Final Calculation Day) is less than its hypothetical Call Value, the Securities are not automatically called. Because the hypothetical Ending Value of the Lowest Performing Underlying on the Final Calculation Day is less than its hypothetical Call Value, but greater than its hypothetical Threshold Value, you would receive the principal amount of your Securities at maturity.

On the Maturity Date, you would receive $1,000.00 per Security.

Example 4. The Securities are not automatically called. The Ending Value of the Lowest Performing Underlying on the Final Calculation Day is less than its Threshold Value and the Maturity Payment Amount is less than the principal amount:

	Nasdaq-100^® Index	SPDR^® S&P^® Biotech ETF	SPDR^® S&P^® Oil & Gas Exploration & Production ETF
Hypothetical Starting Value:	100.00	$100.00	$100.00

In this example, the Nasdaq-100^® Index has the lowest Performance Factor and is, therefore, the Lowest Performing Underlying on the Final Calculation Day.

Step 2: Determine the Maturity Payment Amount based on the Ending Value of the Lowest Performing Underlying on the Final Calculation Day.

Because the hypothetical closing value of the Lowest Performing Underlying on each Call Date (including the Final Calculation Day) is less than its hypothetical Call Value, the Securities are not automatically called. Because the hypothetical Ending Value of the Lowest Performing Underlying on the Final Calculation Day is less than its hypothetical Threshold Value, you would lose a portion of the principal amount of your Securities and receive the Maturity Payment Amount equal to:

= $1,000 × Performance Factor of the Lowest Performing Underlying on the Final Calculation Day

= $1,000 × 50.00% = $500.00

On the Maturity Date, you would receive $500.00 per Security, resulting in a loss of 50.00%. As this example illustrates, if any Underlying depreciates below its Threshold Value on the Final Calculation Day, you will incur a loss on the Securities at maturity, even if the other Underlyings have appreciated or have not declined below their respective Threshold Values.

The Nasdaq-100^® Index

The Nasdaq-100^® Index

The NDX is intended to measure the performance of the 100 largest domestic and international non-financial securities listed on The Nasdaq Stock Market (“NASDAQ”) based on market capitalization. The NDX reflects companies across major industry groups including computer hardware and software, telecommunications, retail/wholesale trade and biotechnology. It does not contain securities of financial companies including investment companies.

The NDX began trading on January 31, 1985 at a base value of 125.00. The NDX is calculated and published by Nasdaq, Inc. In administering the NDX, Nasdaq, Inc. will exercise reasonable discretion as it deems appropriate.

Underlying Stock Eligibility Criteria

NDX eligibility is limited to specific security types only. The security types eligible for the NDX include foreign or domestic common stocks, ordinary shares, ADRs and tracking stocks. Security types not included in the NDX are closed-end funds, convertible debt securities, exchange traded funds, limited liability companies, limited partnership interests, preferred stocks, rights, shares or units of beneficial interest, warrants, units, and other derivative securities. The NDX does not contain securities of investment companies. For purposes of the NDX eligibility criteria, if the security is a depositary receipt representing a security of a non-U.S. issuer, then references to the “issuer” are references to the issuer of the underlying security.

Initial Eligibility Criteria

To be eligible for initial inclusion in the NDX, a security must be listed on NASDAQ and meet the following criteria:

●	the security’s U.S. listing must be exclusively on the Nasdaq Global Select Market or the Nasdaq Global Market (unless the security was dually listed on another U.S. market prior to January 1, 2004 and has continuously maintained such listing);

●	the security must be of a non-financial company;

●	the security may not be issued by an issuer currently in bankruptcy proceedings;

●	the security must have a minimum three-month average daily trading volume of at least 200,000 shares;

●	if the issuer of the security is organized under the laws of a jurisdiction outside the U.S., then such security must have listed options on a recognized options market in the U.S. or be eligible for listed-options trading on a recognized options market in the U.S.;

●	the issuer of the security may not have entered into a definitive agreement or other arrangement which would likely result in the security no longer being eligible for inclusion in the NDX;

●	the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn; and

PS-21

Market Linked Securities—Auto-Callable with Contingent Downside

●	the issuer of the security must have “seasoned” on NASDAQ, the New York Stock Exchange or NYSE Amex. Generally, a company is considered to be seasoned if it has been listed on a market for at least three full months (excluding the first month of initial listing).

Continued Eligibility Criteria

In addition, to be eligible for continued inclusion in the NDX, the following criteria apply:

●	the security’s U.S. listing must be exclusively on the Nasdaq Global Select Market or the Nasdaq Global Market;

●	the security must be of a non-financial company;

●	the security may not be issued by an issuer currently in bankruptcy proceedings;

●	the security must have a minimum three-month average daily trading volume of at least 200,000 shares;

●

if the issuer of the security is organized under the laws of a jurisdiction outside the U.S., then such security must have listed options on a recognized options market in the U.S. or be eligible for listed-options trading on a recognized options market in the U.S. (measured annually during the ranking review process);

●

the security must have an adjusted market capitalization equal to or exceeding 0.10% of the aggregate adjusted market capitalization of the NDX at each month-end. In the event a company does not meet this criterion for two consecutive month-ends, it will be removed from the NDX effective after the close of trading on the third Friday of the following month; and

●	the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn.

Computation of the NDX

The value of the NDX equals the aggregate value of the NDX share weights (the “NDX Shares”) of each of the NDX securities multiplied by each such security’s last sale price (last sale price refers to the last sale price on NASDAQ), and divided by the divisor of the NDX. If trading in an NDX security is halted while the market is open, the last traded price for that security is used for all NDX computations until trading resumes. If trading is halted before the market is open, the previous day’s last sale price is used. The formula for determining the NDX value is as follows:

The NDX is ordinarily calculated without regard to cash dividends on NDX securities. The NDX is calculated during the trading day and is disseminated once per second from 09:30:01 to 17:16:00 ET. The closing level of the NDX may change up until 17:15:00 ET due to corrections to the last sale price of the NDX securities. The official closing value of the NDX is ordinarily disseminated at 17:16:00 ET.

NDX Maintenance

Changes to NDX Constituents

Changes to the NDX constituents may be made during the annual ranking review. In addition, if at any time during the year other than the annual review, it is determined that an NDX security issuer no longer meets the criteria for continued inclusion in the NDX, or is otherwise determined to have become ineligible for continued inclusion in the NDX, it is replaced with the largest market capitalization issuer not currently in the NDX that meets the applicable eligibility criteria for initial inclusion in the NDX.

Ordinarily, a security will be removed from the NDX at its last sale price. However, if at the time of its removal the NDX security is halted from trading on its primary listing market and an official closing price cannot readily be determined, the NDX security may, in Nasdaq, Inc.’s discretion, be removed at a price of $0.00000001 (“zero price”). This zero price will be applied to the NDX security after the close of the market but prior to the time the official closing value of the NDX is disseminated.

Divisor Adjustments

PS-22

Market Linked Securities—Auto-Callable with Contingent Downside

The divisor is adjusted to ensure that changes in the NDX constituents either by corporate actions (that adjust either the price or shares of an NDX security) or NDX participation outside of trading hours do not affect the value of the NDX. All divisor changes occur after the close of the applicable index security markets.

Quarterly NDX Rebalancing

The NDX will be rebalanced on a quarterly basis if it is determined that (1) the current weight of the single NDX security with the largest market capitalization is greater than 24.0% of the NDX or (2) the collective weight of those securities whose individual current weights are in excess of 4.5% exceeds 48.0% of the NDX. In addition, a “special rebalancing” of the NDX may be conducted at any time if Nasdaq, Inc. determines it necessary to maintain the integrity and continuity of the NDX. If either one or both of the above weight distribution conditions are met upon quarterly review, or Nasdaq, Inc. determines that a special rebalancing is necessary, a weight rebalancing will be performed.

If the first weight distribution condition is met and the current weight of the single NDX security with the largest market capitalization is greater than 24.0%, then the weights of all securities with current weights greater than 1.0% (“large securities”) will be scaled down proportionately toward 1.0% until the adjusted weight of the single largest NDX security reaches 20.0%.

If the second weight distribution condition is met and the collective weight of those securities whose individual current weights are in excess of 4.5% (or adjusted weights in accordance with the previous step, if applicable) exceeds 48.0% of the NDX, then the weights of all such large securities in that group will be scaled down proportionately toward 1.0% until their collective weight, so adjusted, is equal to 40.0%.

The aggregate weight reduction among the large securities resulting from either or both of the rebalancing steps above will then be redistributed to those securities with weightings of less than 1.0% (“small securities”) in the following manner. In the first iteration, the weight of the largest small security will be scaled upwards by a factor which sets it equal to the average NDX weight of 1.0%. The weights of each of the smaller remaining small securities will be scaled up by the same factor reduced in relation to each security’s relative ranking among the small securities such that the smaller the NDX security in the ranking, the less its weight will be scaled upward. This is intended to reduce the market impact of the weight rebalancing on the smallest component securities in the NDX.

In the second iteration of the small security rebalancing, the weight of the second largest small security, already adjusted in the first iteration, will be scaled upwards by a factor which sets it equal to the average NDX weight of 1.0%. The weights of each of the smaller remaining small securities will be scaled up by this same factor reduced in relation to each security’s relative ranking among the small securities such that, once again, the smaller the security in the ranking, the less its weight will be scaled upward. Additional iterations will be performed until the accumulated increase in weight among the small securities equals the aggregate weight reduction among the large securities that resulted from the rebalancing in accordance with the two weight distribution conditions discussed above.

Finally, to complete the rebalancing process, once the final weighting percentages for each NDX security have been set, the NDX Shares will be determined anew based upon the last sale prices and aggregate capitalization of the NDX at the close of trading on the last calendar day in February, May, August and November. Changes to the NDX Shares will be made effective after the close of trading on the third Friday in March, June, September and December, and an adjustment to the divisor is made to ensure continuity of the NDX. Ordinarily, new rebalanced NDX Shares will be determined by applying the above procedures to the current NDX Shares. However, Nasdaq, Inc. may, from time to time, determine rebalanced weights, if necessary, by applying the above procedure to the actual current market capitalization of the NDX components. In such instances, Nasdaq, Inc. would announce the different basis for rebalancing prior to its implementation.

During the quarterly rebalancing, data is cutoff as of the previous month end and no changes are made to the NDX from that cutoff until the quarterly index share change effective date, except in the case of changes due to corporate actions with an ex-date.

Adjustments for Corporate Actions

Changes in the price and/or NDX Shares driven by corporate events such as stock dividends, splits, and certain spin-offs and rights issuances will be adjusted on the ex-date. If the change in total shares outstanding arising from other corporate actions is greater than or equal to 10.0%, the change will be made as soon as practicable. Otherwise, if the change in total shares outstanding is less than 10.0%, then all such changes are accumulated and made effective at one time on a quarterly basis after the close of trading on the third

PS-23

Market Linked Securities—Auto-Callable with Contingent Downside

Friday in each of March, June, September, and December. The NDX Shares are derived from the security’s total shares outstanding. The NDX Shares are adjusted by the same percentage amount by which the total shares outstanding have changed.

The SPDR^® S&P^® Biotech ETF

The XBI seeks to provide investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P^® Biotechnology Select Industry^® Index (the “underlying index”). The underlying index represents the biotechnology sub-industry portion of the Standard & Poor’s (“S&P”) Total Market Index (“S&P TMI”), an index that measures the performance of the U.S. equity market. The XBI is composed of companies that are in the biotechnology sector. The XBI trades on NYSE Arca under the ticker symbol “XBI.”

The XBI utilizes a “replication” investment approach in attempting to track the performance of its underlying index. The XBI typically invests in substantially all of the securities which comprise the underlying index in approximately the same proportions as the underlying index. The XBI will normally invest at least 80% of its total assets in the common stocks that comprise the underlying index.

The shares of the XBI are registered under the Securities Exchange Act of the 1934, as amended. Accordingly, information filed with the SEC relating to the XBI, including its period financial reports, may be found on the SEC website.

The S&P^® Biotechnology Select Industry^® Index

This underlying index is an equal-weighted index that is designed to measure the performance of the biotechnology sub-industry portion of the S&P TMI. The S&P TMI includes all U.S. common equities listed on the New York Stock Exchange (the “NYSE”) (including NYSE Arca), the NYSE American, the Nasdaq Global Select Market, the Nasdaq Global Market, the Nasdaq Capital Market and CBOE exchanges. Each of the component stocks in the underlying index is a constituent company within the biotechnology sub-industry portion of the S&P TMI.

To be eligible for inclusion in the underlying index, companies must be in the S&P TMI and must be included in the relevant Global Industry Classification Standard (GICS) sub-industry. The GICS was developed to establish a global standard for categorizing companies into sectors and industries. In addition to the above, companies must satisfy one of the two following combined size and liquidity criteria:

●	float-adjusted market capitalization above US$500 million and float-adjusted liquidity ratio above 90%; or

●	float-adjusted market capitalization above US$400 million and float-adjusted liquidity ratio above 150%.

All U.S. companies satisfying these requirements are included in the underlying index. The total number of companies in the underlying index should be at least 35. If there are fewer than 35 stocks, stocks from a supplementary list of highly correlated sub-industries that meet the market capitalization and liquidity thresholds above are included in order of their float-adjusted market capitalization to reach 35 constituents. Minimum market capitalization requirements may be relaxed to ensure there are at least 22 companies in the underlying index as of each rebalancing effective date.

Eligibility factors include:

●	Market Capitalization: Float-adjusted market capitalization should be at least US$400 million for inclusion in the underlying index. Existing index components must have a float-adjusted market capitalization of US$300 million to remain in the underlying index at each rebalancing.

●

Liquidity: The liquidity measurement used is a liquidity ratio, defined as dollar value traded over the previous 12-months divided by the float-adjusted market capitalization as of the underlying index rebalancing reference date. Stocks having a float-adjusted market capitalization above US$500 million must have a liquidity ratio greater than 90% to be eligible for addition to the underlying index. Stocks having a float-adjusted market capitalization between US$400 and US$500 million must have a liquidity ratio greater than 150% to be eligible for addition to the underlying index. Existing index constituents must have a liquidity ratio greater than 50% to remain in the underlying index at the quarterly rebalancing. The length of time to evaluate liquidity is reduced to the available trading period for IPOs or spin-offs that do not have 12 months of trading history.

●

Takeover Restrictions: At the discretion of S&P, constituents with shareholder ownership restrictions defined in company bylaws may be deemed ineligible for inclusion in the underlying index. Ownership restrictions preventing entities from replicating the index weight of a company may be excluded from the eligible universe or removed from the underlying index.

●	Turnover: S&P believes turnover in index membership should be avoided when possible. At times, a company may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to the underlying index,

PS-26

Market Linked Securities—Auto-Callable with Contingent Downside

not for continued membership. As a result, an index constituent that appears to violate the criteria for addition to the underlying index will not be deleted unless ongoing conditions warrant a change in the composition of the underlying index.

Computation of the XBI

The underlying index is calculated as the underlying index market value divided by the divisor. In an equal-weighted index like the underlying index, the market capitalization of each stock used in the calculation of the index market value is redefined so that each stock has an equal weight in the index on each rebalancing date. The adjusted market capitalization for each stock in the index is calculated as the product of the stock price, the number of shares outstanding, the stock’s float factor and the adjustment factor.

A stock’s float factor refers to the number of shares outstanding that are available to investors. S&P indices exclude shares closely held by control groups from the underlying index calculation because such shares are not available to investors. For each stock, S&P calculates an Investable Weight Factor (IWF) which is the percentage of total shares outstanding that are included in the underlying index calculation.

The adjustment factor for each stock is assigned at each rebalancing date and is calculated by dividing a specific constant set for the purpose of deriving the adjustment factor (often referred to as modified index shares) by the number of stocks in the underlying index multiplied by the float adjusted market value of such stock on such rebalancing date.

Adjustments are also made to ensure that no stock in the underlying index will have a weight that exceeds the value that can be traded in a single day for a theoretical portfolio of $2 billion. Theoretical portfolio values are reviewed annually and any updates are made at the discretion of the underlying index committee, as defined below. The maximum Basket liquidity weight for each stock in the underlying index will be calculated using the ratio of its three-month median daily value traded to the theoretical portfolio value of $2 billion. Each stock’s weight in the underlying index is then compared to its maximum Basket liquidity weight and is set to the lesser of (1) its maximum Basket liquidity weight or (2) its initial equal weight. All excess weight is redistributed across the underlying index to the uncapped stocks. If necessary, a final adjustment is made to ensure that no stock in the underlying index has a weight greater than 4.5%. No further adjustments are made if the latter step would force the weight of those stocks limited to their maximum Basket liquidity weight to exceed that weight. If the underlying index contains exactly 22 stocks as of the rebalancing effective date, the underlying index will be equally weighted without Basket liquidity constraints.

If a company has more than one share class line in the S&P Total Market Index, such company will be represented once by the designated listing (generally the share class with both (i) the highest one-year trading liquidity as defined by median daily value traded and (ii) the largest float-adjusted market capitalization). S&P reviews designated listings on an annual basis and any changes are implemented after the close of the third Friday in September. The last trading day in July is used as the reference date for the liquidity and market capitalization data in such determination. Once a listed share class line is added to the underlying index, it may be retained in the underlying index even though it may appear to violate certain constituent addition criteria. For companies that issue a second publicly traded share class to underlying index share class holders, the newly issued share class line will be considered for inclusion if the event is mandatory and the market capitalization of the distributed class is not considered to be de minimis.

The underlying index is calculated by using the divisor methodology used in all S&P equity indices. The initial divisor was set to have a base value of 1,000 on June 20, 2003. The underlying index level is the underlying index market value divided by the Underlying index divisor. In order to maintain underlying index series continuity, it is also necessary to adjust the divisor at each rebalancing. Therefore, the divisor (after rebalancing) equals the underlying index market value (after rebalancing) divided by the underlying index value before rebalancing. The divisor keeps the underlying index comparable over time and is one manipulation point for adjustments to the underlying index, which we refer to as maintenance of the underlying index.

Structuring the Securities

The Securities are our debt securities, the return on which is linked to the performance of the Underlyings. The related guarantee is BAC’s obligation. Any payments on the Securities, including payment of the Maturity Payment Amount, depend on the credit risk of BofA Finance and BAC and on the performance of the Underlyings. As is the case for all of our and BAC’s respective debt securities, including our market-linked securities, the economic terms of the Securities reflect our and BAC’s actual or perceived creditworthiness at the time of pricing. In addition, because market-linked securities result in increased operational, funding and liability management costs to us and BAC, BAC typically borrows the funds under these types of securities 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 Securities, along with the fees and charges associated with market-linked securities, typically results in the initial estimated value of the Securities on the Pricing Date being less than their public offering price.

The initial estimated value range of the Securities is set forth on the cover page of this preliminary pricing supplement. The final pricing supplement will set forth the initial estimated value of the Securities as of the Pricing Date.

In order to meet our payment obligations on the Securities, at the time we issue the Securities, 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, the tenor of the Securities and the hedging arrangements. The economic terms of the Securities 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.

Market Linked Securities—Auto-Callable with Contingent Downside

U.S. Federal Income Tax Summary

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

•	There is no statutory, judicial, or administrative authority directly addressing the characterization of the Securities.

•

You agree with us (in the absence of an administrative determination, or judicial ruling to the contrary) to characterize and treat the Securities for all tax purposes as single financial contracts with respect to the Underlyings. In the opinion of Sidley Austin LLP, our tax counsel, the U.S. federal income tax characterization and treatment of the Securities described herein is a reasonable interpretation of current law.

•

Under this characterization and tax treatment of the Securities, a U.S. Holder (as defined on page 71 of the accompanying prospectus) generally will recognize capital gain or loss upon maturity or upon a sale, exchange or redemption of the Securities. This capital gain or loss generally will be long-term capital gain or loss if you held the Securities 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 accompanying product supplement), if any, will not apply to Securities that are issued as of the date of this pricing supplement unless such Securities are “delta-one” instruments. Based on our determination that the Securities are not delta-one instruments, Non-U.S. Holders should not be subject to withholding on dividend equivalent payments, if any, under the Securities.

•

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, the Securities are 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 the Securities.

You should consult your own tax advisor concerning the U.S. federal income tax consequences to you of acquiring, owning, and disposing of the Securities, 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-36 of the accompanying product supplement.
