The securities are our senior debt securities. Any payments on the securities are fully and unconditionally guaranteed by Bank of America Corporation (“BAC”).

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 significant loss; there is no guaranteed return of principal.

Any positive investment return on the securities is limited.

The securities do not bear interest.

The securities are subject to potential early redemption, 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.

The early redemption payment or payment at maturity, as applicable, will not reflect changes in the price of the underlying stock other than on the related determination dates or the final determination date, as applicable.

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 Stock-related Risks

The Underlying Company will have no obligations relating to the securities.

The business activities of us, the Guarantor and any of our other affiliates, including BofAS, relating to the Underlying Company may create conflicts of interest with you.

The terms of the securities will not be adjusted for all corporate events that could affect the Underlying Company.

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.
