**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.

· The notes do not pay interest, and any return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

· Any positive return on your investment is limited to the return represented by the Capped Value and may be less than a comparable investment directly in shares of the Market Measure or the securities held by the Market Measure.

· Payments on the notes are subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes.

· The initial estimated value of the notes on the pricing date, based on our proprietary pricing models, will be less than the public offering price because costs associated with offering, structuring and hedging the notes are included in the public offering price, but are not included in the initial estimated value.

· To determine the terms of the notes, we use an internal funding rate that represents a discount from the credit spreads for our conventional fixed-rate debt. As a result, the terms of the notes are less favorable to you than if we had used a higher funding rate.

· The initial estimated value of the notes is not an indication of the price, if any, at which we, BofAS or any of our respective affiliates or any other person may be willing to buy the notes from you in the secondary market (if any).

· A trading market is not expected to develop for the notes.

· Our business, hedging and trading activities, and those of MLPF&S, BofAS and our respective affiliates (including trading in shares of the Market Measure or the securities held by the Market Measure), and any hedging and trading activities we, MLPF&S, BofAS or our respective affiliates engage in for our clients' accounts, may adversely affect the market value of and return on the notes and may create conflicts of interest with you.

· There may be potential conflicts of interest involving the calculation agents, one of which is our affiliate and one of which is BofAS.

· The sponsor and advisor of the Market Measure may adjust the Market Measure in a way that affects its value, and these entities have no obligation to consider your interests.

· The sponsor of the index underlying the Underlying Fund may adjust such index in a way that affects its level, and has no obligation to consider your interests.

· You will have no rights of a holder of shares of the Market Measure or the securities held by the Market Measure, and you will not be entitled to receive securities or dividends or other distributions by the issuers of those securities.

· While we, MLPF&S, BofAS or our respective affiliates may from time to time own shares of the Market Measure or the securities held by the Market Measure, we, MLPF&S, BofAS and our respective affiliates do not control the Market Measure or any company included in the Market Measure, and have not verified any disclosure made by any other company.

· There are liquidity and management risks associated with the Market Measure.

· The performance of the Market Measure may not correlate with the performance of the securities held by the Market Measure as well as the net asset value per share of the Market Measure, especially during periods of market volatility when the liquidity and the market price of shares of the Market Measure and/or the securities held by the Market Measure may be adversely affected, sometimes materially.

· The Redemption Amount will not be adjusted for all corporate events that could affect the Market Measure. See "Description of the ARNs—Anti-Dilution and Discontinuance Adjustments Relating to Underlying Funds" in product supplement EQUITY ARN-1.

· The U.S. federal income tax consequences of an investment in the notes are unclear.

· The equity securities composing the Market Measure are concentrated in the aerospace and defense sector.

· A limited number of securities held by the Market Measure may affect its price, and the securities held by the Market Measure are not necessarily representative of the aerospace and defense sector.

***Final terms will be set on the pricing date within the given range for the specified Market-Linked Investment. Please see the Preliminary Offering Documents for complete product disclosure, including related risks and tax disclosure.***
