Click on the Preliminary Offering Documents hyperlink above or call your Financial Advisor for a hard copy.* Risk Factors Please see the Preliminary Offering Documents for a description of certain risks related to this investment, including, but not limited to, the following: ● Depending on the performance of the Market Measure as measured shortly before the maturity date, your investment may result in a loss; there is no guaranteed return of principal. ● Payments on the notes are subject to the credit risk of BofA Finance and the credit risk of BAC, and actual or perceived changes in the creditworthiness of BofA Finance or BAC are expected to affect the value of the notes. If BofA Finance and BAC become insolvent or are unable to pay their respective obligations, you may lose your entire investment. ● Your investment return is limited to the return represented by the Capped Value and may be less than a comparable investment directly in the stocks included in the Basket Components. ● Changes in the level of one of the Basket Components may be offset by changes in the level of the other Basket Components. ● The initial estimated value of the notes on the pricing date will be less than their public offering price. ● If you attempt to sell the notes prior to maturity, their market value may be lower than both the public offering price and the initial estimated value of the notes on the pricing date. ● You will have no rights of a holder of the securities included in the Basket Components, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities. ● Your return on the notes may be affected by factors affecting the international securities markets, specifically changes in the countries represented by the Basket Components. In addition, you will not obtain the benefit of any increase in the value of the currencies in which the securities included in the Basket Components trade against the U.S. dollar which you would have received if you had owned the securities in the Basket Components during the term of your notes, although the value of the Basket may be adversely affected by general exchange rate movements in the market. ● An investment in the notes will involve risks associated with investments that are linked to the equity securities of issuers from emerging markets. ● The removal of Russian securities from the MXEF may have a material adverse effect on the notes. Final terms will be set on the pricing date within the given range for the specified Market-Linked Investment.
