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.

Risks Relating to an Investment in the Trigger PLUS

●The Trigger PLUS do not pay interest or guarantee return of any principal.

●The appreciation potential of the Trigger PLUS is limited by the maximum payment at maturity.

●The market price of the Trigger PLUS will be influenced by many unpredictable factors.

●The Trigger PLUS 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 Trigger PLUS.

●The amount payable on the Trigger PLUS is not linked to the basket closing value at any time other than the valuation date.

●Investing in the Trigger PLUS is not equivalent to investing in the basket components.

●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 Trigger PLUS in the original issue price reduce the economic terms of the Trigger PLUS, cause the estimated value of the Trigger PLUS to be less than the original issue price and will adversely affect secondary market prices.

●The estimated value of the Trigger PLUS is approximately $923.20 per Trigger PLUS, or within $35.00 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.

●The Trigger PLUS will not be listed on any securities exchange and secondary trading may be limited.

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

●Hedging and trading activity by our affiliates could potentially adversely affect the value of the Trigger PLUS.

●The U.S. federal income tax consequences of an investment in the Trigger PLUS are uncertain.

Risks Relating to the Basket Components

●Changes in the values of the basket components may offset each other.

●Basket stock prices can be volatile.

●There are risks associated with investments in securities linked to the value of equity securities issued by a foreign company.

●We are not affiliated with the issuers of the basket stocks.

●We may engage in business with or involving one or more of the issuers of the basket stocks without regard to your interests.

●The share closing prices of the basket stocks may come to be based on the value of the stock of companies other than the issuers of the basket stocks.

●Governmental regulatory actions, such as sanctions, could adversely affect your investment in the Trigger PLUS.

●The adjustments to the adjustment factors the calculation agent is required to make do not cover every corporate event that can affect the basket stocks.
