●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 price of the Underlying 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.

●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, or any amounts payable on, 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 adversely 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 Underlying, and therefore the Securities are subject to the following risks, each as discussed in more detail in the accompanying product supplement.

oChanges that affect the Underlying or its fund underlying index may adversely affect the value of the Securities and any payments on the Securities.

oWe cannot control actions by any of the unaffiliated companies whose securities are included in the Underlying or its fund underlying index.

oWe and our affiliates have no affiliation with the fund sponsor or fund underlying index sponsor and have not independently verified their public disclosure of information.

oRisks associated with the fund underlying index, or the underlying assets of the Underlying, will affect the value of the Underlying and hence the value of the Securities.

oThere are risks associated with funds.

●Adverse conditions in the information technology sector may reduce your return on the Securities.

●The stocks held by the IGV are concentrated in one sector.

●The anti-dilution adjustments will be limited.

●The performance of the IGV may not correlate with the performance of its fund underlying index as well as the net asset value per share or unit of the IGV, especially during periods of market volatility.

●The U.S. federal income and estate tax consequences of the Securities are uncertain, and may be adverse to a holder of the Securities.
