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 Market Measure or the stocks held by the Market Measure. ●    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 Market Measure or the securities held by the Market Measure, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities. ●    There are liquidity and management risks associated with the Market Measure. ●    All of the securities held by the Market Measure are concentrated in one sector. ●    The performance of the Market Measure may not correlate with the performance of its underlying index as well as the net asset value per share of the Market Measure, especially during periods of market volatility. ●    The sponsor of the Energy Select Sector Index, which is the underlying index of the Market Measure, may adjust the Underlying Index in a way that affects its level, and has no obligation to consider your interests. ●    The stocks of companies in the energy sector are subject to swift price fluctuations. Final terms will be set on the pricing date within the given range for the specified Market-Linked Investment.
