A U.S. Holder should not be required to recognize taxable income over the term of the Buffered PLUS prior to settlement, other than pursuant to a sale or exchange.

§

Upon sale, exchange or settlement of the Buffered PLUS, a U.S. Holder should recognize gain or loss equal to the difference between the amount realized and the U.S. Holder’s tax basis in the Buffered PLUS. Subject to the discussion below concerning the potential application of the “constructive ownership” rule, such gain or loss should be long-term capital gain or loss if the investor has held the Buffered PLUS for more than one year, and short-term capital gain or loss otherwise.

Because the Buffered PLUS are linked to shares of an exchange-traded fund, although the matter is not clear, there is a substantial risk that an investment in the Buffered PLUS will be treated as a “constructive ownership transaction” under Section 1260 of the Internal Revenue Code of 1986, as amended (the “Code”). If this treatment applies, all or a portion of any long-term capital gain of the U.S. Holder in respect of the Buffered PLUS could be recharacterized as ordinary income (in which case an interest charge will be imposed). Due to the lack of governing authority, our counsel is unable to opine as to whether or how Section 1260 of the Code applies to the Buffered PLUS. U.S. investors should read the section entitled “United States Federal Taxation—Tax Consequences to U.S. Holders—Possible Application of Section 1260 of the Code” in the accompanying product supplement for PLUS for additional information and consult their tax advisers regarding the potential application of the “constructive ownership” rule.

In 2007, the U.S. Treasury Department and the Internal Revenue Service (the “IRS”) released a notice requesting comments on the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments.  The notice focuses in particular on whether to require holders of these instruments to accrue income over the term of their investment.  It also asks for comments on a number of related topics, including the character of income or loss with respect to these instruments; whether short-term instruments should be subject to any such accrual regime; the relevance of factors such as the exchange-traded status of the instruments and the nature of the underlying property to which the instruments are linked; the degree, if any, to which income (including any mandated accruals) realized by non-U.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” rule, as discussed above.  While the notice requests comments on appropriate transition rules and effective dates, any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the Buffered PLUS, possibly with retroactive effect.

As discussed in the accompanying product supplement for PLUS, Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% (or a lower applicable treaty rate) withholding tax on dividend equivalents paid or deemed paid to Non-U.S. Holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities (each, an “Underlying Security”).  Subject to certain exceptions, Section 871(m) generally applies to securities that substantially replicate the economic performance of one or more Underlying Securities, as determined based on tests set forth in the

applicable Treasury regulations (a “Specified Security”).  However, pursuant to an IRS notice, Section 871(m) will not apply to securities issued before January 1, 2021 that do not have a delta of one with respect to any Underlying Security.  Based on our determination that the Buffered PLUS do not have a delta of one with respect to any Underlying Security, our counsel is of the opinion that the Buffered PLUS should not be Specified Securities and, therefore, should not be subject to Section 871(m).

Our determination is not binding on the IRS, and the IRS may disagree with this determination.  Section 871(m) is complex and its application may depend on your particular circumstances, including whether you enter into other transactions with respect to an Underlying Security.  If withholding is required, we will not be required to pay any additional amounts with respect to the amounts so withheld.  You should consult your tax adviser regarding the potential application of Section 871(m) to the Buffered PLUS.

Both U.S. and non-U.S. investors considering an investment in the Buffered PLUS should read the discussion under “Risk Factors” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for PLUS and consult their tax advisers regarding all aspects of the U.S. federal income tax consequences of an investment in the Buffered PLUS, including possible alternative treatments, the potential application of the constructive ownership rule, the issues presented by the aforementioned notice and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.  

The discussion in the preceding paragraphs under “Tax considerations” and the discussion contained in the section entitled “United States Federal Taxation” in the accompanying product supplement for PLUS, insofar as they purport to describe provisions of U.S. federal income tax laws or legal conclusions with respect thereto, constitute the full opinion of Davis Polk & Wardwell LLP regarding the material U.S. federal tax consequences of an investment in the Buffered PLUS.

The proceeds from the sale of the Buffered PLUS will be used by us for general corporate purposes.  We will receive, in aggregate, $1,000 per Buffered PLUS issued, because, when we enter into hedging transactions in order to meet our obligations under the Buffered PLUS, our hedging counterparty will reimburse the cost of the agent’s commissions.  The costs of the Buffered PLUS borne by you and described on page 2 above comprise the agent’s commissions and the cost of issuing, structuring and hedging the Buffered PLUS.

On or prior to the pricing date, we will hedge our anticipated exposure in connection with the Buffered PLUS, by entering into hedging transactions with our affiliates and/or third party dealers.  We expect our hedging counterparties to take positions in underlying shares, futures and options contracts on the underlying shares, and any component stocks of the share underlying index listed on major securities markets or positions in any other available securities or instruments that they may wish to use in connection with such hedging.  Such purchase activity could potentially increase the price of the underlying shares on the pricing date, and, therefore, could increase the price at or above which the underlying shares must close on the valuation date so that investors do not suffer a loss on their initial investment in the Buffered PLUS.  In addition, through our affiliates, we are likely to modify our hedge position throughout the term of the Buffered PLUS, including on the valuation date, by purchasing and selling the underlying shares, futures or options contracts on the underlying shares or component stocks of the share underlying index listed on major securities markets or positions in any other available securities or instruments that we may wish to use in connection with such hedging activities.  As a result, these entities may be unwinding or adjusting hedge positions during the term of the Buffered PLUS, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the valuation date approaches.  We cannot give any assurance that our hedging activities will not affect the value of the underlying shares, and, therefore, adversely affect the value of the Buffered PLUS or the payment you will receive at maturity, if any.  For further information on our use of proceeds and hedging, see “Use of Proceeds and Hedging” in the accompanying product supplement for PLUS.

Each fiduciary of a pension, profit-sharing or other employee benefit plan subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) (a “Plan”), should consider the fiduciary standards of ERISA in the context of the Plan’s particular circumstances before authorizing an investment in the Buffered PLUS.  Accordingly, among other factors, the fiduciary should consider whether the investment would satisfy the prudence and diversification requirements of ERISA and would be consistent with the documents and instruments governing

the Plan.

In addition, we and certain of our affiliates, including MS & Co., may each be considered a “party in interest” within the meaning of ERISA, or a “disqualified person” within the meaning of the Internal Revenue Code of 1986, as amended (the “Code”), with respect to many Plans, as well as many individual retirement accounts and Keogh plans (such accounts and plans, together with other plans, accounts and arrangements subject to Section 4975 of the Code, also “Plans”).  ERISA Section 406 and Section 4975 of the Code generally prohibit transactions between Plans and parties in interest or disqualified persons.  Prohibited transactions within the meaning of ERISA or the Code would likely arise, for example, if the Buffered PLUS are acquired by or with the assets of a Plan with respect to which MS & Co. or any of its affiliates is a service provider or other party in interest, unless the Buffered PLUS are acquired pursuant to an exemption from the “prohibited transaction” rules.  A violation of these “prohibited transaction” rules could result in an excise tax or other liabilities under ERISA and/or Section 4975 of the Code for those persons, unless exemptive relief is available under an applicable statutory or administrative exemption.

The U.S. Department of Labor has issued five prohibited transaction class exemptions (“PTCEs”) that may provide exemptive relief for direct or indirect prohibited transactions resulting from the purchase or holding of the Buffered PLUS.  Those class exemptions are PTCE 96-23 (for certain transactions determined by in-house asset managers), PTCE 95-60 (for certain transactions involving insurance company general accounts), PTCE 91-38 (for certain transactions involving bank collective investment funds), PTCE 90-1 (for certain transactions involving insurance company separate accounts) and PTCE 84-14 (for certain transactions determined by independent qualified professional asset managers).  In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code provide an exemption for the purchase and sale of securities and the related lending transactions, provided that neither the issuer of the securities nor any of its affiliates has or exercises any discretionary authority or control or renders any investment advice with respect to the assets of the Plan involved in the transaction and provided further that the Plan pays no more, and receives no less, than “adequate consideration” in connection with the transaction (the so-called “service provider” exemption).  There can be no assurance that any of these class or statutory exemptions will be available with respect to transactions involving the Buffered PLUS.

Because we may be considered a party in interest with respect to many Plans, the Buffered PLUS may not be purchased, held or disposed of by any Plan, any entity whose underlying assets include “plan assets” by reason of any Plan’s investment in the entity (a “Plan Asset Entity”) or any person investing “plan assets” of any Plan, unless such purchase, holding or disposition is eligible for exemptive relief, including relief available under PTCEs 96-23, 95-60, 91-38, 90-1, 84-14 or the service provider exemption or such purchase, holding or disposition is otherwise not prohibited.  Any purchaser, including any fiduciary purchasing on behalf of a Plan, transferee or holder of the Buffered PLUS will be deemed to have represented, in its corporate and its fiduciary capacity, by its purchase and holding of the Buffered PLUS that either (a) it is not a Plan or a Plan Asset Entity and is not purchasing such Buffered PLUS on behalf of or with “plan assets” of any Plan or with any assets of a governmental, non-U.S. or church plan that is subject to any federal, state, local or non-U.S. law that is substantially similar to the provisions of Section 406 of ERISA or Section 4975 of the Code (“Similar Law”) or (b) its purchase, holding and disposition of these Buffered PLUS will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code or violate any Similar Law.

Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that fiduciaries or other persons considering purchasing the Buffered PLUS on behalf of or with “plan assets” of any Plan consult with their counsel regarding the availability of exemptive relief.

The Buffered PLUS are contractual financial instruments.  The financial exposure provided by the Buffered PLUS is not a substitute or proxy for, and is not intended as a substitute or proxy for, individualized investment management or advice for the benefit of any purchaser or holder of the Buffered PLUS.  The Buffered PLUS have not been designed and will not be administered in a manner intended to reflect the individualized needs and objectives of any purchaser or holder of the Buffered PLUS.

Each purchaser or holder of any Buffered PLUS acknowledges and agrees that:

(i)       

the purchaser or holder or its fiduciary has made and shall make all investment decisions for the purchaser or holder and the purchaser or holder has not relied and shall not rely in any way upon us or our affiliates to act as a fiduciary or adviser of the purchaser or holder with respect to (A) the design and terms of the Buffered PLUS, (B) the purchaser or holder’s investment in the Buffered PLUS, or (C) the exercise of or failure to exercise any rights we have under or with respect to the Buffered PLUS;

(ii)       

we and our affiliates have acted and will act solely for our own account in connection with (A) all transactions relating to the Buffered PLUS and (B) all hedging transactions in connection with our obligations under the Buffered PLUS;

(iii)       

any and all assets and positions relating to hedging transactions by us or our affiliates are assets and positions of those entities and are not assets and positions held for the benefit of the purchaser or holder;

(iv)       

our interests are adverse to the interests of the purchaser or holder; and

(v)       

neither we nor any of our affiliates is a fiduciary or adviser of the purchaser or holder in connection with any such assets, positions or transactions, and any information that we or any of our affiliates may provide is not intended to be impartial investment advice.

Each purchaser and holder of the Buffered PLUS has exclusive responsibility for ensuring that its purchase, holding and disposition of the Buffered PLUS do not violate the prohibited transaction rules of ERISA or the Code or any Similar Law.  The sale of any Buffered PLUS to any Plan or plan subject to Similar Law is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by plans generally or any particular plan, or that such an investment is appropriate for plans generally or any particular plan. In this regard, neither this discussion nor anything provided in this document is or is intended to be investment advice directed at any potential Plan purchaser or at Plan purchasers generally and such purchasers of the Buffered PLUS should consult and rely on their own counsel and advisers as to whether an investment in the Buffered PLUS is suitable.

However, individual retirement accounts, individual retirement annuities and Keogh plans, as well as employee benefit plans that permit participants to direct the investment of their accounts, will not be permitted to purchase or hold the Buffered PLUS if the account, plan or annuity is for the benefit of an employee of Morgan Stanley or Morgan Stanley Wealth Management or a family member and the employee receives any compensation (such as, for example, an addition to bonus) based on the purchase of the Buffered PLUS by the account, plan or annuity.

Selected dealers, which may include our affiliates, and their financial advisors will collectively receive from the agent, MS & Co., a fixed sales commission of $     for each Buffered PLUS they sell.
