Hypothetical Payout Profile***

*** prepared for purposes of illustration only; assumes a Call Premium equal to the lowest possible Call Premium that may be determined on the Pricing Date.

If the Securities are not automatically called and the Ending Price of the Lowest Performing Underlying Stock on the Final Calculation Day is less than its Threshold Price, you will lose more than 30%, and possibly all, of the principal amount of your Securities on the Maturity Date.

Any positive return on the Securities will be limited to any applicable Call Premium, even if the stock closing price of the Lowest Performing Underlying Stock on the applicable Call Date significantly exceeds its Starting Price. You will not participate in any appreciation of any Underlying Stock beyond any applicable Call Premium.

The initial estimated value of the Securities as of the pricing date is expected to be between $910.00 and $960.00 per Security, which is less than the public offering price. 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-9 of the accompanying preliminary pricing supplement and “Structuring the Securities” on page PS-20 of the accompanying preliminary pricing supplement for additional information.

Selected Risk Considerations

The risks set forth below, as well as additional risks related to this investment, are discussed in detail in the “Selected Risk Considerations” section in the accompanying preliminary pricing supplement.  Please review those risk disclosures carefully.

●    Your investment may result in a loss; there is no guaranteed return of principal. ●    Any positive investment return on the Securities is limited. ●    The Securities do not bear interest. ●    The amount payable upon an automatic call or the Maturity Payment Amount, as applicable, will not reflect the prices of the Underlying Stocks other than on the Call Dates. ●    The Securities are subject to a potential automatic call, which would limit your ability to receive further payment on the Securities. ●    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 Starting Price or Threshold Price. ●    Your return on the Securities may be less than the yield on a conventional debt security of comparable maturity. ●    A Call Settlement Date and the Maturity Date may be postponed if a Call Date is postponed. ●    Any payment on the Securities is subject to the credit risk of BofA Finance, as issuer, and BAC, as Guarantor, and actual or perceived changes in BofA Finance’s or the Guarantor’s creditworthiness are expected to affect the value of the Securities. ●    We are a finance subsidiary and, as such, have no independent assets, operations or revenues. ●    The public offering price you pay for the Securities will exceed their initial estimated value. ●    The initial estimated value does not represent a minimum or maximum price at which BofA Finance, BAC, BofAS or any of our other affiliates or Wells Fargo Securities, LLC (“WFS”) or its affiliates would be willing to purchase your Securities in any secondary market (if any exists) at any time. ●    BofA Finance cannot assure you that a trading market for your Securities will ever develop or be maintained. ●    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.  ●    Trading and hedging activities by BofA Finance, 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. ●    There may be potential conflicts of interest involving the calculation agent, which is an affiliate of ours. ●    Any payments on the Securities and whether the Securities are automatically called will depend upon the performance of the UnderlyingStocks, and therefore the Securities are subject to the following risks, each as discussed in more detail in the accompanying product supplement. o    The Securities may become linked to the common stock of a company other than an original Underlying Stock Issuer. o    We cannot control actions by an Underlying Stock Issuer. o    We and our affiliates have no affiliation with any Underlying Stock Issuer and have not independently verified any public disclosure of information. o    You have limited anti-dilution protection. ●    The U.S. federal income and estate tax consequences of the Securities are uncertain, and may be adverse to a holder of the Securities.
