Principal at Risk Securities
This document provides a summary of the terms of the securities. Investors must carefully review the accompanying preliminary pricing supplement referenced below, product supplement, prospectus supplement and prospectus, and the “Risk Considerations” on the following page, prior to making an investment decision.
The securities do not guarantee the repayment of principal and do not provide for the regular payment of interest. Investors will not participate in any appreciation of the S&P 500® Index. The securities are for investors who seek an opportunity to earn contingent quarterly coupon payments at a potentially above-market rate in exchange for the risk of losing their principal and the risk of receiving no contingent quarterly coupon when the S&P 500® Index on the related observation date closes below the coupon barrier level, and the risk of an early redemption of the securities at our discretion. The securities are our senior debt securities. Any payments on the securities are fully and unconditionally guaranteed by Bank of America Corporation (“BAC”). The securities are issued as part of BofA Finance LLC’s (“BofA Finance”) “Medium-Term Notes, Series A” program.

Risk Considerations
The risks set forth below are discussed in more detail in the “Risk Factors” section in the accompanying preliminary pricing supplement. Please review those risk factors carefully prior to making an investment decision.
Structure-related Risks
■   
Your investment may result in a loss; there is no guaranteed return of principal.
■   
Your return on the securities is limited to the return represented by the contingent quarterly coupons, if any, over the term of the securities.
■   
The securities are subject to early redemption, which would limit your ability to receive the contingent quarterly coupons over the full term of the securities
■   
You may not receive any contingent quarterly coupons.
■   
Your return on the securities may be less than the yield on a conventional debt security of comparable maturity.
■   
The contingent quarterly coupon, redemption payment or payment at maturity, as applicable, will not reflect changes in the level of the underlying index other than on the observation dates.
■   
Any payments on the securities are subject to our credit risk and the credit risk of the guarantor, and any actual or perceived changes in our or the guarantor’s creditworthiness are expected to affect the value of the securities.
■   
We are a finance subsidiary and, as such, have no independent assets, operations, or revenues.
Valuation- and Market-related Risks
■   
The price to public 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 we, BAC, BofAS or any of our other affiliates would be willing to purchase your securities in any secondary market (if any exists) at any time.
■   
We cannot assure you that a trading market for your securities will ever develop or be maintained.
Conflict-related Risks
■   
Trading and hedging activities by us, the guarantor and any of our other affiliates, including BofAS, may create conflicts of interest with you and may 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.
Underlying Index-related Risks
■   
The publisher of the underlying index may adjust the underlying index in a way that affects its levels, and the publisher has no obligation to consider your interests.
Tax-related Risks
■   
The U.S. federal income tax consequences of an investment in the securities are uncertain, and may be adverse to a holder of the securities.
Tax Considerations
You should review carefully the discussion in the accompanying preliminary pricing supplement under the caption “Additional Information About the Securities—Tax considerations” concerning the U.S. federal income tax consequences of an investment in the securities, and you should consult your tax adviser.
