Tax considerations

See preliminary pricing supplement

Any return on the notes will be limited to the sum of your coupon payments. You will not participate in any appreciation of any underlying stock.

The principal amount of each note is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the notes, which are borne by you, and, consequently, the estimated value of the notes on the pricing date will be less than $1,000 per note. We estimate that the value of each note on the pricing date will be approximately $942.00, or within $40.00 of that estimate. Our estimate of the value of the notes as determined on the pricing date will be set forth in the final pricing supplement. See “Investment Summary” and “Risk Factors” in the accompanying preliminary pricing supplement for further information.

This document provides a summary of the terms of the notes. Investors should carefully review the accompanying preliminary pricing supplement, product supplement, tax supplement and prospectus before making a decision to invest in the notes.

The notes have complex features and investing in the notes involves risks not associated with an investment in ordinary debt securities. See “Risk Factors” in the accompanying preliminary pricing supplement and tax supplement. All payments on the notes are subject to our credit risk.

This introductory term sheet does not provide all of the information that an investor should consider prior to making an investment decision.

The notes are not deposits or savings accounts and are not insured by the Federal Deposit Insurance Corporation or any other governmental agency or instrumentality, nor are they obligations of, or guaranteed by, a bank.


Selected risk considerations

The risks set forth below are discussed in more detail in the “Risk Factors” section in the accompanying preliminary pricing supplement, product supplement, tax supplement and prospectus. Please review those risk factors carefully.

Risks Relating to an Investment in the Notes

You may receive a positive return of only the lower coupon amount on the notes.

The coupon amount payable is based on the stock closing price of each underlying stock on only the related monthly calculation day 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 notes 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 notes.

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

Investing in the notes is not equivalent to investing in the underlying stocks.

Reinvestment risk.

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 notes in the principal amount reduce the economic terms of the notes, cause the estimated value of the notes to be less than the principal amount and will adversely affect secondary market prices.

The estimated value of the notes 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 notes 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 notes.

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

The maturity date may be postponed if the final calculation day is postponed.

Potentially inconsistent research, opinions or recommendations by Morgan Stanley, MSFL, WFS or our or their respective affiliates.

You may be required to recognize taxable income on the securities offered by the accompanying preliminary pricing supplement prior to maturity.

 

Risks Relating to the Underlying Stocks

You are exposed to the price risk of each underlying stock with respect to the coupon payments.

Because the notes are linked to the performance of the lowest performing underlying stock, you are exposed to greater risks of receiving only the lower coupon amount than if the notes were linked to just one underlying stock.

No affiliation with Alphabet Inc., Broadcom Inc., Microsoft Corporation or NVIDIA Corporation.

We may engage in business with or involving Alphabet Inc., Broadcom Inc., Microsoft Corporation or NVIDIA 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.

Historical closing prices of the underlying stocks should not be taken as an indication of the future performance of the underlying stocks during the term of the notes.

For more information about the underlying stocks, including historical performance information, see the accompanying preliminary pricing supplement.
