Risk Considerations

The risks set forth below are discussed in more detail in the “Risk Factors” section in the accompanying preliminary terms. Please review those risk factors carefully prior to making an investment decision.

· The securities do not guarantee the return of any principal.

· The securities do not provide for the regular payment of interest and may pay no interest over the entire term of the securities.

· You are exposed to the price risk of all of the underlying stocks, with respect to both the contingent quarterly coupons, if any, and the payment at maturity, if any.

· The contingent coupon, if any, is based only on the determination closing prices of the underlying stocks on the related quarterly coupon observation date at the end of the related interest period.

· Investors will not participate in any appreciation in the price of any underlying stock.

· The market price will be influenced by many unpredictable factors.

· The securities are subject to our credit risk, and any actual or anticipated changes to our credit ratings or credit spreads may adversely affect the market value of the securities.

· The estimated value of the securities is approximately $943.40 per security, or within $30.00 of that estimate, and is determined by reference to our pricing and valuation models, which may differ from those of other dealers and is not a maximum or minimum secondary market price.

· As a finance subsidiary, MSFL has no independent operations and will have no independent assets.

· Reinvestment risk.

· Investing in the securities is not equivalent to investing in the common stock of Apple Inc., the common stock of Amazon.com, Inc. or the common stock of Microsoft Corporation.

· No affiliation with Apple Inc., Amazon.com, Inc. or Microsoft Corporation.

· We may engage in business with or involving Apple Inc., Amazon.com, Inc. or Microsoft Corporation without regard to your interests.

· The antidilution adjustments the calculation agent is required to make do not cover every corporate event that could affect the underlying stocks.

· The securities will not be listed on any securities exchange and secondary trading may be limited, and accordingly, you should be willing to hold your securities for the entire 3-year term of the securities.

· The rate we are willing to pay for securities of this type, maturity and issuance size is likely to be lower than the rate implied by our secondary market credit spreads and advantageous to us. Both the lower rate and the inclusion of costs associated with issuing, selling, structuring and hedging the securities in the original issue price reduce the economic terms of the securities, cause the estimated value of the securities to be less than the original issue price and will adversely affect secondary market prices.

· Hedging and trading activity by our affiliates could potentially affect the value of the securities.

· The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the securities.

· The U.S. federal income tax consequences of an investment in the securities are uncertain.

Tax Considerations

You should review carefully the discussion in the accompanying preliminary terms 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.
