Risk Considerations

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

Risks Relating to an Investment in the Securities

●The securities do not guarantee the return of any principal and do not pay interest.

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

●The amount payable on the securities is not linked to the values of the underliers at any time other than the observation date.

●The market price of the securities may 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.

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

●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.

●The estimated value of the securities 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 securities will not be listed on any securities exchange and secondary trading may be limited.

●As discussed in more detail in the accompanying product supplement, investing in the securities is not equivalent to investing in the underlier(s).

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

Risks Relating to the Underlier(s)

●Because your return on the securities will depend upon the performance of the underlier(s), the securities are subject to the following risk(s), as discussed in more detail in the accompanying product supplement.

oYou are exposed to the price risk of each underlier.

oBecause the securities are linked to the performance of the worst performing underlier, you are exposed to a greater risk of not receiving a positive return on the securities and/or sustaining a loss on your investment than if the securities were linked to just one underlier.

oAdjustments to an underlying fund or the index tracked by such underlying fund could adversely affect the value of the securities.

oThe performance and market price of an underlying fund, particularly during periods of market volatility, may not correlate with the performance of its share underlying index, the performance of the component securities of its share underlying index or the net asset value per share of such underlying fund.

oInvestments linked to commodities are subject to sharp fluctuations in commodity prices.

oSingle commodity prices tend to be more volatile than, and may not correlate with, the prices of commodities generally.

oThe performance and market price of an underlying fund, particularly during periods of market volatility, may not correlate with the performance of its share underlying commodity or the net asset value per share of such underlying fund.

oThe anti-dilution adjustments the calculation agent is required to make do not cover every event that could affect an underlying fund.

●The securities are subject to risks associated with gold.

●There are risks relating to trading of commodities on the London Bullion Market Association.

●Suspensions or disruptions of market trading in commodity and related futures markets could adversely affect the value of the securities.

●The securities are subject to risks associated with silver.

●There are risks relating to trading of commodities on the London Bullion Market Association.

Risks Relating to Conflicts of Interest

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

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

Tax Considerations

You should review carefully the discussion in the accompanying amended preliminary pricing supplement under the caption "Additional Information About the Securities- United States federal income tax considerations" concerning the U.S. federal income tax consequences of an investment in the securities, and you should consult your tax adviser.
