You should read the relevant Preliminary Offering Documents before you invest. 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.  ●    Your potential for a positive return based on the depreciation of the Market Measure is limited. The absolute value return feature applies only if the Ending Value is less than the Starting Value but greater than or equal to the Threshold Value. Because the Threshold Value is 85.00% of the Starting Value, any positive return due to the depreciation of the Market Measure is limited to 15.00%. Any decline in the Ending Value from the Starting Value by more than 15.00% will result in a loss, rather than a positive return, on the notes. ●    Your investment return based on any increase of the Market Measure is limited to the return represented by the Capped Value ●    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. ●    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. ●    Ownership of the notes will not entitle you to any rights with respect to any commodities or futures contracts represented by or included in the Market Measure. ●    An investment linked to commodity futures contracts is not equivalent to an investment linked to the spot prices of physical commodities.  ●    Suspensions or disruptions of trading in the Market Measureor any related futures contracts may adversely affect the value of the notes. ●    Legal and regulatory changes could adversely affect the return on and value of your notes. ●    Changes in the exchange methodology related to the Market Measure may adversely affect the value of the notes prior to maturity. ●    The notes will not be regulated by the U.S. Commodity Futures Trading Commission. ●    Single commodity prices tend to be more volatile than, and may not correlate with, the prices of commodities generally. ●    The price movements in the Market Measure may not correlate with changes in WTI crude oil’s spot price. ●    The market value of the notes may be affected by price movements in distant-delivery futures contracts associated with the Market Measure. ●    Crude oil prices can be volatile as a result of various factors that we cannot control, and this volatility may reduce the market value of the notes. Final terms will be set on the pricing date within the given range for the specified Market-Linked Investment.
