Market Linked Securities—Leveraged Upside Participation
and Contingent Downside
Principal at Risk Securities Linked to the Lowest Performing of the Common Stock of Apple Inc., the Common Stock of Amazon.com, Inc. and the Class A Common Stock of Alphabet Inc. due December 21, 2026
■   Linked to the lowest performing of the common stock of Apple Inc., the common stock of Amazon.com, Inc. and the class A common stock of Alphabet Inc. (each referred to as an “Underlying Stock”)
■   Unlike ordinary debt securities, the Securities do not pay interest or repay a fixed amount of principal at maturity. Instead, the Securities provide for a Maturity Payment Amount that may be greater than, equal to or less than the principal amount of the Securities, depending on the performance of the Lowest Performing Underlying Stock. The Lowest Performing Underlying Stock is the Underlying Stock that has the lowest Stock Return (i.e., the lowest percentage change from its Starting Price to its Ending Price). The Maturity Payment Amount will reflect the following terms:
■  If the price of the Lowest Performing Underlying Stock increases, you will receive the principal amount plus a positive return equal to at least 203% (to be determined on the Pricing Date) of the percentage increase in the price of the Lowest Performing Underlying Stock from its Starting Price
■  If the price of the Lowest Performing Underlying Stock decreases but the decrease is not more than 25.00%, you will receive the principal amount of your Securities 
■   If the price of the Lowest Performing Underlying Stock decreases by more than 25.00%, you will have full downside exposure to the decrease in the price of the Lowest Performing Underlying Stock from its Starting Price, and you will lose more than 25%, and possibly all, of the principal amount of your Securities
■   Investors may lose a significant portion, and possibly all, of the principal amount 
■  Your return on the Securities will depend solely on the performance of the Lowest Performing Underlying Stock. You will not benefit in any way from the performance of the better performing Underlying Stocks. Therefore, you will be adversely affected if any Underlying Stock performs poorly, even if the other Underlying Stocks perform favorably
■   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 
■   No periodic interest payments or dividends
■   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 $900.00 and $950.00 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-7 of this pricing supplement and “Structuring the Securities” on page PS-17 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-7 herein and “Risk Factors” beginning on page PS-5 of the accompanying product supplement, page S-5 of the accompanying prospectus supplement, and page 7 of the accompanying prospectus. 
None of the Securities and Exchange Commission (the “SEC”), any state securities commission, or any other regulatory body has approved or disapproved of these Securities or determined if this pricing supplement and the accompanying product supplement, prospectus supplement and prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

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 $31.25 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 $22.50 per Security. In addition to the concession allowed to 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 $1.50 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.

Market Linked Securities—Leveraged Upside Participation and Contingent Downside
Principal at Risk Securities Linked to the Lowest Performing of the Common Stock of Apple Inc., the Common Stock of Amazon.com, Inc. and the Class A Common Stock of Alphabet Inc. due December 21, 2026
Investor Considerations
The Securities are not appropriate for all investors. The Securities may be an appropriate investment for investors who:
■   
seek at least 203% (to be determined on the Pricing Date) leveraged exposure to the upside performance of the Lowest Performing Underlying Stock if its Ending Price is greater than its Starting Price; 
■   
desire repayment of the face amount at maturity so long as the Ending Price of the Lowest Performing Underlying Stock is not less than its Starting Price by more than 25%;
■   
are willing to accept the risk that, if the Ending Price of the Lowest Performing Underlying Stock is less than its Starting Price by more than 25%, they will be fully exposed to the decrease in the price of the Lowest Performing Underlying Stock from its Starting Price, and will lose more than 25%, and possibly all, of the face amount at maturity;
■   
understand that the return on the Securities will depend solely on the performance of the Lowest Performing Underlying Stock and that they will not benefit in any way from the performance of the better performing Underlying Stocks;
■   
understand that the Securities are riskier than alternative investments linked to only one of the Underlying Stocks or linked to a basket composed of each Underlying Stock;
■   
understand and are willing to accept the full downside risks of each Underlying Stock;
■   
are willing to forgo interest payments on the Securities and dividends on the Underlying Stocks; 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; 
■   
are unwilling to accept the risk that the Ending Price of the Lowest Performing Underlying Stock may decline by more than 25.00% from its Starting Price; 
■   
require full payment of the principal amount of the Securities at maturity; 
■   
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 Stocks;
■   
seek exposure to a basket composed of each Underlying Stock or a similar investment in which the overall return is based on a blend of the performances of the Underlying Stocks, rather than solely on the Lowest Performing Underlying Stocks; 
■   
seek exposure to the Underlying Stocks but are unwilling to accept the risk/return trade-offs inherent in the Maturity Payment Amount for the Securities; 
■   
are unwilling to accept the credit risk of BofA Finance, as issuer, and BAC, as guarantor, to obtain exposure to the Underlying Stock generally, or to obtain exposure to the Underlying Stock that the Securities provide specifically; or 
■   
prefer the lower risk of 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. For more information about the Underlying Stocks, please see the sections titled “The Common Stock of Apple Inc.,” “The Common Stock of Amazon.com Inc.” and “The Class A Common Stock of Alphabet Inc.” below.

Principal at Risk Securities Linked to the Lowest Performing of the Common Stock of Apple Inc., the Common Stock of Amazon.com, Inc. and the Class A Common Stock of Alphabet Inc. due December 21, 2026
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-5 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. The return on the Securities will be based on the performance of the Lowest Performing Underlying Stock. If the Ending Price of the Lowest Performing Underlying Stock is less than its Threshold Price, you will lose 1% of the principal amount for each 1% that the Ending Price of the Lowest Performing Underlying Stock is less than its Starting Price. In that case, you will lose a significant portion or all of your investment in the Securities.
The Maturity Payment Amount will not reflect changes in the price of the Underlying Stocks other than on the Calculation Day. Changes in the price of the Underlying Stocks during the term of the Securities other than on the Calculation Day will not be reflected in the calculation of the Maturity Payment Amount. No other prices of the Underlying Stocks will be taken into account. As a result, you will receive less than the principal amount at maturity even if the price of any Underlying Stock has increased at certain times during the term of the Securities before any Underlying Stock decreases to a price that is less than its Threshold Price as of the Calculation Day.
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 Ending Price of any Underlying Stock exceeds its Starting Price or Threshold Price. 
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.
The Maturity Date may be postponed if the Calculation Day is postponed.
The Calculation Day with respect to an Underlying Stock will be postponed if the originally scheduled Calculation Day is not a trading day with respect to any Underlying Stock or if the calculation agent determines that a market disruption event has occurred or is continuing with respect to that Underlying Stock on the Calculation Day. If such a postponement occurs, the Maturity Date will be the later of (i) the initial Maturity Date and (ii) three business days after the last Calculation Day as postponed.
Because the Securities are linked to the lowest performing (and not the average performance) of the Underlying Stocks, you may not receive any return on the Securities and may lose a significant portion or all of your principal amount even if the stock closing price of one Underlying Stock is always greater than or equal to its Threshold Price. Your Securities are linked to the lowest performing of the Underlying Stocks, and a change in the price of one Underlying Stock may not correlate with changes in the price of the other Underlying Stock(s). The Securities are not linked to a basket composed of the Underlying Stocks, where the depreciation in the price of one Underlying Stock could be offset to some extent by the appreciation in the price of the other Underlying Stock(s). In the case of the Securities, the individual performance of each Underlying Stock would not be combined, and the depreciation in the price of one Underlying Stock would not be offset by any appreciation in the price of the other Underlying Stock(s). Even if the Ending Price of an Underlying Stock is at or above its Threshold Price, you will lose a significant portion or all of your principal if the Ending Price of the Lowest Performing Underlying Stock is below its Threshold Price.
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 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 Maturity Date, regardless of the stock closing price of the Lowest Performing Underlying Stock as compared to its Starting Price.
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

Market Linked Securities—Leveraged Upside Participation and Contingent Downside
Principal at Risk Securities Linked to the Lowest Performing of the Common Stock of Apple Inc., the Common Stock of Amazon.com, Inc. and the Class A Common Stock of Alphabet Inc. due December 21, 2026
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 prices of the Underlying Stocks, an improvement in our or the Guarantor’s credit ratings will not reduce the other investment risks related to the 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 prices of the Underlying Stocks, 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 Stocks, 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: prices of the Underlying Stocks at such time; volatility of the Underlying Stocks; economic and other conditions generally; interest rates; dividend yields; 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 the Underlying Stocks, or futures or options contracts on the Underlying Stocks, or other listed or over-the-counter derivative instruments linked to the Underlying Stocks. 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 Stocks, we, the Guarantor and our other affiliates, including BofAS, and WFS and its affiliates, do not control any Underlying Stock Issuer, 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 prices of the Underlying Stocks 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 prices of the Underlying Stocks. Consequently, the prices of the Underlying Stocks 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 prices of the Underlying Stocks 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 prices of the Underlying Stocks, 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 will depend upon the performance of the Underlying Stocks, and therefore the Securities are subject to the following risks, each as discussed in more detail in the accompanying product supplement. 
●   
The Securities may become linked to the common stock of a company other than an original Underlying Stock Issuer.
●   
We cannot control actions by an Underlying Stock Issuer.
●   
We and our affiliates have no affiliation with any Underlying Stock Issuer and have not independently verified any public disclosure of information.
●   
You have limited anti-dilution protection.
Tax-related Risks
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.

The payout profile, return table and examples below illustrate the Maturity Payment Amount 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 any actual Starting Price or Threshold Price of any Underlying Stock. The hypothetical Starting Price of $100.00 has been chosen for illustrative purposes only and does not represent the actual Starting Price of any Underlying Stock. The actual Starting Price and Threshold Price of each Underlying Stock 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 Prices of the Underlying Stocks, 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 Maturity Payment Amount and resulting pre-tax total rate of return will depend on the actual terms of the securities. 
Hypothetical Upside Participation Rate: 
203.00% (the lowest possible Upside Participation Rate that may be determined on the Pricing Date)
Hypothetical Starting Price: 
For each Underlying Stock, $100.00
Hypothetical Threshold Price: 
For each Underlying Stock, $75.00 (75% of its hypothetical Starting Price)

Hypothetical Examples 
Example 1. The Ending Price of the Lowest Performing Underlying Stock is greater than its Starting Price and the Maturity Payment Amount is greater than the principal amount of your Securities:
Common Stock of Apple Inc.
Common Stock of Amazon.com, Inc.
Class A Common Stock of Alphabet Inc.
Hypothetical Starting Price: 
$100.00
$100.00
$100.00
Hypothetical Ending Price:
$125.00
$135.00
$140.00
Hypothetical Threshold Price:
$75.00
$75.00
$75.00
Hypothetical Stock Return 
(Ending Price — Starting Price) / Starting Price: 
25.00%
35.00%
40.00%
Step 1: Determine which Underlying Stock is the Lowest Performing Underlying Stock. 
In this example, the common stock of Apple Inc. has the lowest Stock Return and is, therefore, the Lowest Performing Underlying Stock.
Step 2: Determine the Maturity Payment Amount based on the Stock Return of the Lowest Performing Underlying Stock.
Since the hypothetical Ending Price of the Lowest Performing Underlying Stock is greater than its hypothetical Starting Price, the Maturity Payment Amount per Security would be equal to the principal amount of $1,000 plus a positive return equal to:
$1,000 × Stock Return of the Lowest Performing Underlying Stock × Upside Participation Rate
$1,000 × 25.00% × 203.00% = $507.50
On the Maturity Date, you would receive $1,507.50 per Security.

Principal at Risk Securities Linked to the Lowest Performing of the Common Stock of Apple Inc., the Common Stock of Amazon.com, Inc. and the Class A Common Stock of Alphabet Inc. due December 21, 2026
Example 2. The Ending Price of the Lowest Performing Underlying Stock is less than its Starting Value but greater than its Threshold Price and the Maturity Payment Amount is equal to the principal amount of your Securities:
Common Stock of Apple Inc.
Common Stock of Amazon.com, Inc.
Class A Common Stock of Alphabet Inc.
Hypothetical Starting Price: 
$100.00
$100.00
$100.00
Hypothetical Ending Price:

$135.00
$140.00

$75.00
$75.00
Hypothetical Stock Return 
(Ending Price — Starting Price) / Starting Price: 
-5.00%
35.00%
40.00%
Step 1: Determine which Underlying Stock is the Lowest Performing Underlying Stock. 
In this example, the common stock of Apple Inc. has the lowest Stock Return and is, therefore, the Lowest Performing Underlying Stock.
Step 2: Determine the Maturity Payment Amount based on the Stock Return of the Lowest Performing Underlying Stock.
Since the hypothetical Ending Price of the Lowest Performing Underlying Stock is less than its hypothetical Starting Price, but not more than 25% you would be repaid the principal amount of your Securities at maturity.
On the Maturity Date, you would receive $1,000.00 per Security.
Example 3. The Ending Price of the Lowest Performing Underlying Stock is less than its Threshold Price and the Maturity Payment Amount is less than the principal amount of your Securities: 
Common Stock of Apple Inc.
Common Stock of Amazon.com, Inc.
Class A Common Stock of Alphabet Inc.
Hypothetical Starting Price: 
$100.00
$100.00
$100.00
Hypothetical Ending Price:
$50.00
$135.00
$140.00
Hypothetical Threshold Price:
$75.00
$75.00
$75.00
Hypothetical Stock Return 
(Ending Price — Starting Price) / Starting Price: 
-50.00%
35.00%
40.00%
Step 1: Determine which Underlying Stock is the Lowest Performing Underlying Stock. 
In this example, the common stock of Apple Inc. has the lowest Stock Return and is, therefore, the Lowest Performing Underlying Stock.
Step 2: Determine the Maturity Payment Amount based on the Stock Return of the Lowest Performing Underlying Stock.
Since the hypothetical Ending Price of the Lowest Performing Underlying Stock is less than its hypothetical Threshold Price, you would lose a portion of the principal amount of your Securities and receive a Maturity Payment Amount equal to:
$1,000 + ($1,000 × Stock Return of the Lowest Performing Underlying Stock)
$1,000 + ($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 Stock depreciates below its Threshold Price on the Calculation Day, you will incur a loss on the Securities at maturity, even if the other Underlying Stocks have appreciated or have not declined below their respective Threshold Prices.

Structuring the Securities
The Securities are our debt securities, the return on which is linked to the performance of the Underlying Stocks. 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 Stocks. 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 Stocks, 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
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 Underlying Stocks. 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 beginning on page 38 of the accompanying prospectus) generally will recognize capital gain or loss upon maturity or upon a sale or exchange 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.
