&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ■ Linked to the S&P 500<sup>®</sup> Index (the "Underlying") <br> ■ 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 level of the Underlying on the applicable Call Date <br> ■ **Automatic Call.** If the closing level of the Underlying on any Call Date is greater than or equal to the Starting 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 8.50% per annum (to be determined on the Pricing Date) <br> \| Call Date \| Call Premium\* \|<br> \|:---\|:---\|<br> \| April 4, 2024 \| At least 8.500% of the principal amount \|<br> \| July 5, 2024 \| At least 10.625% of the principal amount \|<br> \| October 4, 2024 \| At least 12.750% of the principal amount \|<br> \| January 6, 2025 \| At least 14.875% of the principal amount \|<br> \| April 4, 2025 \| At least 17.000% of the principal amount \|<br> \| July 7, 2025 \| At least 19.125% of the principal amount \|<br> \| October 6, 2025 \| At least 21.250% of the principal amount \|<br> \| January 5, 2026 \| At least 23.375% of the principal amount \|<br> \| April 6, 2026 \| At least 25.500% of the principal amount \|<br> \| July 6, 2026 \| At least 27.625% of the principal amount \|<br> \| October 5, 2026 \| At least 29.750% of the principal amount \|<br> \| January 4, 2027 \| At least 31.875% of the principal amount \|<br> \| April 5, 2027 \| At least 34.000% of the principal amount \|<br> \| July 6, 2027 \| At least 36.125% of the principal amount \|<br> \| October 4, 2027 \| At least 38.250% of the principal amount \|<br> \| January 4, 2028 \| At least 40.375% of the principal amount \|<br> \| March 28, 2028 (the "Final Calculation Day") \| At least 42.500% of the principal amount \| \* The actual Call Premium applicable to each Call Date will be determined on the Pricing Date <br> ■ **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 level of the Underlying on the Final Calculation Day as follows: <br> ■ <br> If the closing level of the Underlying on the Final Calculation Day is less than the Starting Value, but not by more than the buffer amount of 10.00%, you will receive the principal amount of your Securities <br>■ <br> If the closing level of the Underlying on the Final Calculation Day is less than the Starting Value by more than the buffer amount, you will receive less than the principal amount and have 1-to-1 downside exposure to the decrease in the level of the Underlying in excess of the buffer amount <br>■ Investors may lose up to 90.00% of the principal amount <br> ■ Any positive return on the Securities will be limited to the applicable Call Premium, even if the closing level of the Underlying on the applicable Call Date significantly exceeds the Starting Value. You will not participate in any appreciation of the Underlying beyond the applicable fixed Call Premium <br> ■ 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 <br> ■ Securities will not be listed on any securities exchange <br> ■ No periodic interest payments <br>

**The initial estimated value of the Securities as of the Pricing Date is expected to be between $900 and $950 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-8 of this pricing supplement and "Structuring the Securities" on page PS-19 of this pricing supplement for additional information. <br>**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-8 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.** <br>**None of the Securities and Exchange Commission (the "SEC"), any state securities commission, or any other regulatory body has approved or disapproved of these Securities or determined if this pricing supplement and the accompanying product supplement, prospectus supplement and prospectus is truthful or complete.

| &nbsp;&nbsp; **Maturity Payment Amount:**  | &nbsp;&nbsp; If the Securities are not automatically called, then on the Maturity Date, you will be entitled to receive a cash payment per Security in U.S. dollars equal to the Maturity Payment Amount. The "<u>Maturity Payment Amount</u>" per Security will be calculated as follows: <br>&nbsp;&nbsp;&nbsp;&nbsp;• if the Ending Value is less than the Starting Value but greater than or equal to the Threshold Value: $1,000; or <br>&nbsp;&nbsp;&nbsp;&nbsp;• if the Ending Value is less than the Threshold Value: $1,000 *minus*: <br> ![](image_001.jpg) <br> **If the Securities are not automatically called and the Ending Value is less than the Threshold Value, you will receive less, and possibly 90.00% less, than the principal amount of your Securities at maturity.**  |

| &nbsp;&nbsp; **Starting Value:**  | &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;, which is the closing level of the Underlying on the Pricing Date.  |

| &nbsp;&nbsp; **Threshold Value:**  | &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;, which is equal to 90.00% of the Starting Value.  |
| &nbsp;&nbsp; **Market Disruption Events and Postponement Provisions:**  | &nbsp;&nbsp; Each Call Date (including the Final Calculation Day) is subject to postponement due to non-trading days and the occurrence of a market disruption event. 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" in the accompanying product supplement.  |

| &nbsp;&nbsp; **Selling Agents:**  | &nbsp;&nbsp; <br>In addition, in respect of certain Securities sold in this offering, BofAS or its affiliates may pay a fee of up to $5.00 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. <br>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 five-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 five-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. <br>|
| &nbsp;&nbsp;&nbsp; **Events of Default** <br> **and Acceleration:**  | &nbsp;&nbsp; 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 level of the Underlying on the date of acceleration is equal to or greater than the Starting 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.  |
| &nbsp;&nbsp;&nbsp; **Material Tax** <br> **Consequences:**  | &nbsp;&nbsp; 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."  |

**Market Linked Securities—Auto-Callable with Fixed Percentage Buffered Downside** <br> **Principal at Risk Securities Linked to the S&P 500**<sup>®</sup> **Index due April 4, 2028** <br>

**Investor Considerations** <br>

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

■ believe that the closing level of the Underlying will be greater than or equal to the Starting Value on one of the Call Dates;

■ seek the potential for a fixed return if the Underlying has appreciated at all as of any of the Call Dates in lieu of full participation in any potential appreciation of the Underlying;

■ are willing to accept the risk that, if the closing level of the Underlying is less than the Starting 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 the Underlying on the Final Calculation Day is less than the Starting Value by more than the buffer amount of 10.00%, they will receive less, and possibly 90.00% less, than 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;

■ are willing to forgo interest payments on the Securities and dividends on securities included in the Underlying; 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 level of the Underlying will be less than the Starting Value on each Call Date;

■ seek a security with a fixed term;

■ are unwilling to accept the risk that, if the closing level of the Underlying is less than the Starting 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 level of the Underlying may decrease by more than the buffer amount of 10.00% from the Starting Value to the 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 Underlying;

■ seek exposure to the upside performance of the 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 Underlying generally, or to obtain exposure to the Underlying 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.

**Selected Risk Considerations** <br>

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.

**<u>Structure-related Risks</u>**

**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 Underlying is less than the Threshold Value, at maturity, you will lose 1% of the principal amount for each 1% that the Ending Value of the Underlying is less than the Threshold Value. In that case, you will lose some or a significant portion of your investment in the Securities.

**Any positive investment return on the Securities is limited.** You will not participate in any increase in the level of the Underlying. Any positive investment return is limited to the applicable Call Premium, if any, regardless of the extent to which the closing level of the Underlying on any Call Date exceeds the Starting Value. In contrast, a direct investment in the securities included in the Underlying 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 securities included in or held by the Underlying. 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 level of the Underlying exceeds the Starting Value or Threshold Value on any Call Date.

**The Call Premium or Maturity Payment Amount, as applicable, will not reflect the level of the Underlying other than on the Call Dates.** The levels of the Underlying 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 Underlying while holding the Securities, as the performance of the Underlying may influence the market value of the Securities. The calculation agent will determine whether the Securities will be automatically called, and will calculate the Call Premium or the Maturity Payment Amount, as applicable, by comparing only the Starting Value or Threshold Value, as applicable, to the closing level of the Underlying on the applicable Call Date. No other levels of the Underlying will be taken into account. As a result, if the Securities are not automatically called, and the Ending Value of the Underlying is less than the Threshold Value, you will receive less than the principal amount at maturity even if the level of the Underlying was always above the 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 level of the Underlying is greater than or equal to the Starting 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.

**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 the Underlying will be postponed if the applicable originally scheduled Call Date is not a trading day with respect to the Underlying or if the calculation agent determines that a market disruption event has occurred or is continuing with respect to the Underlying on that Call Date. If such a postponement occurs with respect to a 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 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 level of the Underlying as compared to the

------

**Market Linked Securities—Auto-Callable with Fixed Percentage Buffered Downside** <br> **Principal at Risk Securities Linked to the S&P 500**<sup>®</sup> **Index due April 4, 2028** <br>

Starting 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 level of the Underlying, 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.

**<u>Valuation- and Market-related Risks</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br>**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 level of the Underlying, 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 Underlying, 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.

**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: level of the Underlying at such time; volatility of the Underlying; 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.

**<u>Conflict-related Risks</u>**

**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 the securities held by or included in the Underlying, or futures or options contracts on the Underlying or those securities, or other listed or over-the-counter derivative instruments linked to the Underlying 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 securities represented by the Underlying, except to the extent that BAC's or Wells Fargo & Company's (the parent company of WFS) common stock may be included in the Underlying, as applicable, we, the Guarantor and our other affiliates, including BofAS, and WFS and its affiliates, do not control any company included in the Underlying, 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 level of the Underlying 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 level of the Underlying. Consequently, the level of the Underlying may change subsequent to the Pricing Date, which may adversely affect the market value of the Securities.

**Market Linked Securities—Auto-Callable with Fixed Percentage Buffered Downside** <br> **Principal at Risk Securities Linked to the S&P 500**<sup>®</sup> **Index due April 4, 2028** <br>

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 level of the Underlying 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 level of the Underlying, 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.

**<u>Underlying-related Risks</u>** <br>

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

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

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

**<u>Tax-related Risks</u>** <br>

**The U.S. federal income and estate tax consequences of the Securities are uncertain, and may be adverse to a holder of the Securities.** See "U.S. Federal Income Tax Summary" below and "U.S. Federal Income Tax Summary" beginning on page PS-36 of the accompanying product supplement.

**Hypothetical Examples and Returns** <br>

The payout profile, hypothetical returns and examples below illustrate hypothetical payments upon an automatic call or at maturity for a $1,000 principal amount security on a hypothetical offering of securities under various scenarios, with the assumptions set forth in the table below. The terms used for purposes of these hypothetical examples do not represent the actual Starting Value or Threshold Value of the Underlying. The hypothetical Starting Value of 100.00 for the Underlying has been chosen for illustrative purposes only and does not represent the actual Starting Value of the Underlying. The actual Starting Value and Threshold Value for the Underlying will be determined on the Pricing Date and will be set forth under "Terms of the Securities" above. For historical data regarding the actual closing levels of the Underlying, see the historical information set forth herein. The payout profile, return table and examples below assume that an investor purchases the Securities for $1,000 per Security. These examples are for purposes of illustration only and the values used in the examples may have been rounded for ease of analysis. The actual amount you receive at stated maturity or upon automatic call and the resulting pre-tax total rate of return will depend on the actual terms of the Securities.

**Hypothetical Examples Of Payment Upon An Automatic Call Or At Maturity**

**Example 1. The closing level of the Underlying on the first Call Date is greater than the Starting Value, and the Securities are automatically called on the first Call Date:**

---

| | |
|:---|:---|
|  | **S&P 500<sup>®</sup> Index**  |
| &nbsp;&nbsp; **Hypothetical Starting Value:**  | 100.00  |
| &nbsp;&nbsp; **Hypothetical closing level on first Call Date:**  | 125.00  |

---

Because the hypothetical closing level of the Underlying on the first Call Date is greater than the hypothetical Starting 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 8.50% of the principal amount. Even though the Underlying appreciated by 25.00% from the Starting Value to its closing level on the first Call Date in this example, your return is limited to the Call Premium of 8.50% that is applicable to such Call Date.

On the Call Settlement Date, you would receive $1,085.00 per Security.

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

| &nbsp;&nbsp; **Hypothetical closing level on Final Calculation Day:**  | 120.00  |

---

Because the hypothetical closing level of the Underlying on each Call Date prior to the last Call Date (which is the Final Calculation Day) is less than the hypothetical Starting Value, the Securities are not called prior to the Final Calculation Day. Because the hypothetical closing level of the Underlying on the Final Calculation Day is greater than the hypothetical Starting Value, the Securities are automatically called 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 42.50% of the principal amount.

On the Call Settlement Date (which is the Maturity Date), you would receive $1,425.00 per Security

**Hypothetical Payments at Stated Maturity (Continued)** <br>

**Example 3. The Securities are not automatically called. The Ending Value is less than the Starting Value but greater than the Threshold Value and the Maturity Payment Amount is equal to the principal amount:** 

---

| | |
|:---|:---|
|  | **S&P 500<sup>®</sup> Index**  |
| &nbsp;&nbsp; **Hypothetical Starting Value:**  | 100.00  |
| &nbsp;&nbsp; **Hypothetical closing levels on Call Dates prior to the Final Calculation Day:**  | Various (all **below** Starting Value)  |
| &nbsp;&nbsp; **Hypothetical Ending Value:**  | 95.00  |
| &nbsp;&nbsp; **Hypothetical Threshold Value:**  | 90.00, which is 90.00% of the hypothetical Starting Value  |

---

Because the hypothetical closing level of the Underlying on each Call Date (including the Final Calculation Day) is less than the hypothetical Starting Value, the Securities are not automatically called. Because the hypothetical Ending Value is less than the hypothetical Starting Value, but not by more than the buffer amount of 10.00%, 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 is less than the Threshold Value and the Maturity Payment Amount is less than the principal amount:**

| &nbsp;&nbsp; **Hypothetical Ending Value:**  | 50.00  |
| &nbsp;&nbsp; **Hypothetical Threshold Value:**  | 90.00, which is 90.00% of the hypothetical Starting Value  |

---

Because the hypothetical closing level of the Underlying on each Call Date (including the Final Calculation Day) is less than the hypothetical Starting Value, the Securities are not automatically called. Because the hypothetical Ending Value is less than the hypothetical Starting Value by more than the buffer amount of 10.00%, you would lose a portion of the principal amount of your Securities and would be paid a Maturity Payment Amount equal to:

On the Maturity Date, you would receive $600.00 per Security, resulting in a loss of 40.00%.

All disclosures contained in this pricing supplement regarding the Underlying, 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, S&P Dow Jones Indices LLC ("SPDJI"), the sponsor of the Underlying. We refer to SPDJI as the "Underlying sponsor." The Underlying sponsor, which licenses the copyright and all other rights to the Underlying, has no obligation to continue to publish, and may discontinue publication of, the Underlying. The consequences of the Underlying sponsor discontinuing publication of the Underlying are discussed in "General Terms of the Securities—Discontinuance of the Index" in the accompanying product supplement. None of us, the Guarantor, the calculation agent, or BofAS accepts any responsibility for the calculation, maintenance or publication of the Underlying or any successor index. None of us, the Guarantor, BofAS or any of our other affiliates makes any representation to you as to the future performance of the Underlying. You should make your own investigation into the Underlying.

**The S&P 500<sup>®</sup> Index**

The SPX includes a representative sample of 500 companies in leading industries of the U.S. economy. The SPX is intended to provide an indication of the pattern of common stock price movement. The calculation of the level of the SPX is based on the relative value of the aggregate market value of the common stocks of 500 companies as of a particular time compared to the aggregate average market value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943.

The SPX includes companies from eleven main groups: Communication Services; Consumer Discretionary; Consumer Staples; Energy; Financials; Health Care; Industrials; Information Technology; Real Estate; Materials; and Utilities. SPDJI may from time to time, in its sole discretion, add companies to, or delete companies from, the SPX to achieve the objectives stated above.

Company additions to the SPX must have an unadjusted company market capitalization of $14.6 billion or more (an increase from the previous requirement of an unadjusted company market capitalization of $13.1 billion or more).

SPDJI calculates the SPX by reference to the prices of the constituent stocks of the SPX without taking account of the value of dividends paid on those stocks. As a result, the return on the Securities will not reflect the return you would realize if you actually owned the SPX constituent stocks and received the dividends paid on those stocks.

***Computation of the SPX***

While SPDJI currently employs the following methodology to calculate the SPX, no assurance can be given that SPDJI will not modify or change this methodology in a manner that may affect the payments on the Securities.

Historically, the market value of any component stock of the SPX was calculated as the product of the market price per share and the number of then outstanding shares of such component stock. In March 2005, SPDJI began shifting the SPX halfway from a market capitalization weighted formula to a float-adjusted formula, before moving the SPX to full float adjustment on September 16, 2005. SPDJI's criteria for selecting stocks for the SPX did not change with the shift to float adjustment. However, the adjustment affects each company's weight in the SPX.

Under float adjustment, the share counts used in calculating the SPX reflect only those shares that are available to investors, not all of a company's outstanding shares. Float adjustment excludes shares that are closely held by control groups, other publicly traded companies or government agencies.

In September 2012, all shareholdings representing more than 5% of a stock's outstanding shares, other than holdings by "block owners," were removed from the float for purposes of calculating the SPX. Generally, these "control holders" will include officers and directors, private equity, venture capital and special equity firms, other publicly traded companies that hold shares for control, strategic partners, holders of restricted shares, ESOPs, employee and family trusts, foundations associated with the company, holders of unlisted share classes of stock, government entities at all levels (other than government retirement/pension funds) and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. However, holdings by block owners, such as depositary banks, pension funds, mutual funds and ETF providers, 401(k) plans of the company, government retirement/pension funds, investment funds of insurance companies, asset managers and investment funds, independent foundations and savings and investment plans, will ordinarily be considered part of the float.

Treasury stock, stock options, restricted shares, equity participation units, warrants, preferred stock, convertible stock, and rights are not part of the float. Shares held in a trust to allow investors in countries outside the country of domicile, such as depositary shares and Canadian exchangeable shares are normally part of the float unless those shares form a control block. If a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class are treated as a control block.

For each stock, an investable weight factor ("IWF") is calculated by dividing the available float shares by the total shares outstanding. Available float shares are defined as the total shares outstanding less shares held by control holders. This calculation is subject to a 5% minimum threshold for control blocks. For example, if a company's officers and directors hold 3% of the company's shares, and no other control group holds 5% of the company's shares, SPDJI would assign that company an IWF of 1.00, as no control group meets the 5% threshold. However, if a company's officers and directors hold 3% of the company's shares and another control group holds 20% of the company's shares, SPDJI would assign an IWF of 0.77, reflecting the fact that 23% of the company's outstanding shares are considered

to be held for control. As of July 31, 2017, companies with multiple share class lines are no longer eligible for inclusion in the SPX. Constituents of the SPX prior to July 31, 2017 with multiple share class lines will be grandfathered in and continue to be included in the SPX. If a constituent company of the SPX reorganizes into a multiple share class line structure, that company will remain in the SPX at the discretion of the S&P Index Committee in order to minimize turnover.

The SPX is calculated using a base-weighted aggregate methodology. The level of the SPX reflects the total market value of all component stocks relative to the base period of the years 1941 through 1943. An indexed number is used to represent the results of this calculation in order to make the level easier to work with and track over time. The actual total market value of the component stocks during the base period of the years 1941 through 1943 has been set to an indexed level of 10. This is often indicated by the notation 1941- 43 = 10. In practice, the daily calculation of the SPX is computed by dividing the total market value of the component stocks by the "index divisor." By itself, the index divisor is an arbitrary number. However, in the context of the calculation of the SPX, it serves as a link to the original base period level of the SPX. The index divisor keeps the SPX comparable over time and is the manipulation point for all adjustments to the SPX, which is index maintenance.

***Index Maintenance***

Index maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to company restructuring or spinoffs. Some corporate actions, such as stock splits and stock dividends, require changes in the common shares outstanding and the stock prices of the companies in the SPX, and do not require index divisor adjustments.

To prevent the level of the SPX from changing due to corporate actions, corporate actions which affect the total market value of the SPX require an index divisor adjustment. By adjusting the index divisor for the change in market value, the level of the SPX remains constant and does not reflect the corporate actions of individual companies in the SPX. Index divisor adjustments are made after the close of trading and after the calculation of the SPX closing level.

Changes in a company's shares outstanding of 5.00% or more due to mergers, acquisitions, public offerings, tender offers, Dutch auctions, or exchange offers are made as soon as reasonably possible. Share changes due to mergers or acquisitions of publicly held companies that trade on a major exchange are implemented when the transaction occurs, even if both of the companies are not in the same headline index, and regardless of the size of the change. All other changes of 5.00% or more (due to, for example, company stock repurchases, private placements, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participation units, at-the-market offerings, or other recapitalizations) are made weekly and are announced on Fridays for implementation after the close of trading on the following Friday. Changes of less than 5.00% are accumulated and made quarterly on the third Friday of March, June, September, and December, and are usually announced two to five days prior.

If a change in a company's shares outstanding of 5.00% or more causes a company's IWF to change by five percentage points or more, the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case by case basis.

**Structuring the Securities** <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br>The Securities are our debt securities, the return on which is linked to the performance of the Underlying. 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 Underlying. 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.

**U.S. Federal Income Tax Summary** <br>

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● There is no statutory, judicial, or administrative authority directly addressing the characterization of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● 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 Underlying. 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. 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Under this characterization and tax treatment of the Securities, a U.S. Holder (as defined beginning 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. 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● No assurance can be given that the Internal Revenue Service ("<u>IRS</u>") or any court will agree with this characterization and tax treatment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● 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. 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● 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.**
