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.

●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 the commodity tracked by the Market Measure.

●The price of the Market Measure may change unpredictably, affecting the value of your notes in unforeseeable ways. Trading in commodities is speculative and can be extremely volatile. The Market Measure may decrease to zero or a negative price, which would adversely affect the value of your notes.

●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 notes are subject to risks associated with copper.

●The notes are subject to risks associated with the LME.
