Dual Directional Buffered PLUS Based on the Value of the Worst Performing of the Dow Jones Industrial AverageSM, the NASDAQ100 Index® and the Russell 2000® Index due May 9, 2024
Buffered Performance Leveraged Upside SecuritiesSM
Fully and Unconditionally Guaranteed by Morgan Stanley
Principal at Risk Securities
The Dual Directional Buffered PLUS, or “Buffered PLUS,” are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. The Buffered PLUS will pay no interest, provide a minimum payment at maturity of only 15% of the stated principal amount and have the terms described in the accompanying product supplement for PLUS, index supplement and prospectus, as supplemented or modified by this document. The payment at maturity on the Buffered PLUS will be based on the value of the worst performing of the Dow Jones Industrial AverageSM, the NASDAQ100 Index® and the Russell 2000® Index. At maturity, if the final index value of each underlying index is greater than its respective initial index value, investors will receive the stated principal amount of their investment plus leveraged upside performance of the worst performing underlying index. If the final index value of any underlying index is less than or equal to its respective initial index value, but the final index value of each underlying index is greater than or equal to 85% of its respective initial index value, meaning that no underlying index has decreased from its initial index value by an amount greater than the buffer amount of 15%, investors will receive the stated principal amount of their investment plus an unleveraged positive return based on the absolute value of the performance of the worst performing underlying index, which will be inherently limited to a maximum return of 15%. However, if the final index value of any underlying index is less than 85% of its respective initial index value, meaning that any underlying index has decreased from its respective initial index value by an amount greater than the buffer amount of 15%, the absolute return feature will no longer be available and instead investors will lose 1% for every 1% decline in the worst performing underlying index beyond the specified buffer amount, subject to the minimum payment at maturity of 15% of the stated principal amount. Investors may lose up to 85% of the stated principal amount of the Buffered PLUS. Because the payment at maturity of the Buffered PLUS is based on the worst performing of the underlying indices, a decline in any underlying index beyond the buffer amount will result in a loss, and potentially a significant loss, of your investment even if the other underlying indices have appreciated or have not declined as much. The Buffered PLUS are for investors who seek an equity indexbased return and who are willing to risk their principal, risk exposure to the worst performing of three underlying indices and forgo current income in exchange for the leverage, buffer and absolute return features that in each case apply to a limited range of performance of the worst performing underlying index. The Buffered PLUS are notes issued as part of MSFL’s Series A Global MediumTerm Notes program.
The Buffered PLUS differ from the PLUS described in the accompanying product supplement for PLUS in that the Buffered PLUS offer the potential for a positive return at maturity if the worst performing underlying index depreciates by no more than 15%.
All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment. These Buffered PLUS are not secured obligations and you will not have any security interest in, or otherwise have any access to, any underlying reference asset or assets.

Investment Summary
Buffered Performance Leveraged Upside Securities
Principal at Risk Securities
The Dual Directional Buffered PLUS Based on the Value of the Worst Performing of the Dow Jones Industrial AverageSM, the NASDAQ100 Index® and the Russell 2000® Index due May 9, 2024 (the “Buffered PLUS”) can be used:
￭To gain exposure to the worst performing of three U.S. equity indices
￭To potentially outperform the worst performing of the Dow Jones Industrial AverageSM, the NASDAQ100 Index® and the Russell 2000® Index by taking advantage of the leverage factor
￭To obtain an unleveraged positive return for a limited range of negative performance in the worst performing underlying index
If the final index value of any underlying index is less than 85% of its respective initial index value, investors will be negatively exposed to the decline in the worst performing underlying index beyond the buffer amount and will lose some or a substantial portion of their investment.
Maturity: 
Approximately 3 years 
Leverage factor: 
At least 114%. The actual leverage factor will be determined on the pricing date. 
Minimum payment at maturity: 
$150 per Buffered PLUS (15% of the stated principal amount). Investors may lose up to 85% of the stated principal amount of the Buffered PLUS. 
Buffer amount: 
15%, with 1to1 downside exposure to the worst performing underlying index below the buffer 
Coupon: 
None 
Listing: 
The Buffered PLUS will not be listed on any securities exchange 
The original issue price of each Buffered PLUS is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the Buffered PLUS, which are borne by you, and, consequently, the estimated value of the Buffered PLUS on the pricing date will be less than $1,000. We estimate that the value of each Buffered PLUS on the pricing date will be approximately $965.70, or within $30.00 of that estimate. Our estimate of the value of the Buffered PLUS as determined on the pricing date will be set forth in the final pricing supplement.
What goes into the estimated value on the pricing date?
In valuing the Buffered PLUS on the pricing date, we take into account that the Buffered PLUS comprise both a debt component and a performancebased component linked to the underlying indices. The estimated value of the Buffered PLUS is determined using our own pricing and valuation models, market inputs and assumptions relating to the underlying indices, instruments based on the underlying indices, volatility and other factors including current and expected interest rates, as well as an interest rate related to our secondary market credit spread, which is the implied interest rate at which our conventional fixed rate debt trades in the secondary market.
What determines the economic terms of the Buffered PLUS?
In determining the economic terms of the Buffered PLUS, including the leverage factor, the buffer amount and the minimum payment at maturity, we use an internal funding rate, which is likely to be lower than our secondary market credit spreads and therefore advantageous to us. If the issuing, selling, structuring and hedging costs borne by you were lower or if the internal funding rate were higher, one or more of the economic terms of the Buffered PLUS would be more favorable to you.
What is the relationship between the estimated value on the pricing date and the secondary market price of the Buffered PLUS?
The price at which MS & Co. purchases the Buffered PLUS in the secondary market, absent changes in market conditions, including those related to the underlying indices, may vary from, and be lower than, the estimated value on the pricing date, because the secondary market price takes into account our secondary market credit spread as well as the bidoffer spread that MS & Co. would charge in a secondary market transaction of this type and other factors. However, because the costs associated with issuing, selling, structuring and hedging the Buffered PLUS are not fully deducted upon issuance, for a period of up to 6 months following the issue date, to the extent that MS & Co. may buy or sell the Buffered PLUS in the secondary market, absent changes in market conditions, including those related to the underlying indices, and to our secondary market credit spreads, it would do so based on values higher than the estimated value. We expect that those higher values will also be reflected in your brokerage account statements.
MS & Co. may, but is not obligated to, make a market in the Buffered PLUS, and, if it once chooses to make a market, may cease doing so at any time.

Principal at Risk Securities
Key Investment Rationale
The Buffered PLUS offer the potential for a positive return at maturity based on the absolute value of a limited range of percentage changes of the worst performing underlying index. At maturity, if the final index value of each underlying index is greater than its respective initial index value, investors will receive the stated principal amount of their investment plus leveraged upside performance of the worst performing underlying index. If the final index value of any underlying index is less than or equal to its respective initial index value but the final index value of each underlying index is greater than or equal to 85% of its respective initial index value, investors will receive the stated principal amount of their investment plus an unleveraged positive return based on the absolute value of the performance of the worst performing underlying index. However, if the final index value of any underlying index is less than 85% of its respective initial index value, the absolute return feature will no longer be available and instead investors will lose 1% for every 1% decline in the worst performing underlying index beyond the specified buffer amount, subject to the minimum payment at maturity. Investors may lose up to 85% of the stated principal amount of the Buffered PLUS. All payments on the Buffered PLUS are subject to our credit risk.
Because the payment at maturity of the Buffered PLUS is based on the worst performing of the underlying indices, a decline in any underlying index to less than 85% of its respective initial index value will result in a loss, and potentially a significant loss, of your investment, even if the other underlying indices have appreciated or have not declined as much.

Hypothetical Examples
The following hypothetical examples illustrate how to calculate the payment at maturity on the Buffered PLUS. The following examples are for illustrative purposes only. The actual initial index value for each underlying index will be determined on the pricing date. Any payment at maturity on the Buffered PLUS is subject to our credit risk. The below examples are based on the following terms:
Stated principal amount: 
$1,000 per Buffered PLUS 
Hypothetical leverage factor: 
114%. The actual leverage factor will be determined on the pricing date. 
Hypothetical initial index value: 
With respect to the INDU Index: 25,000 With respect to the NDX Index: 13,000 With respect to the RTY Index: 2,200 
Minimum payment at maturity: 
$150 per Buffered PLUS (15% of the stated principal amount) 
Buffer amount: 
15% 
EXAMPLE 1: The final index value of each underlying index is greater than its respective initial index value.
Final index value 

INDU Index: 37,500 



NDX Index: 20,800 



RTY Index: 3,080 

Index percent change 

INDU Index: (37,500 – 25,000) / 25,000 = 50% NDX Index: (20,800 – 13,000) / 13,000 = 60% RTY Index: (3,080 – 2,200) / 2,200 = 40% 

Payment at maturity 
= 
$1,000 + ($1,000 × leverage factor × index percent change of the worst performing underlying index) 


= 
$1,000 + ($1,000 × 114% × 40%) 


= 
$1,456 
In example 1, the final index value of each of the INDU Index, the NDX Index and the RTY Index is greater than its respective initial index value. The INDU Index has appreciated by 50%, the NDX Index has appreciated by 60% and the RTY Index has appreciated by 40%. Therefore, investors receive at maturity the stated principal amount plus 114% of the appreciation of the worst performing underlying index, which is the RTY Index in this example. Investors receive $1,456 per Buffered PLUS at maturity (assuming a hypothetical leverage factor of 114%). The actual leverage factor will be determined on the pricing date.
EXAMPLE 2: The final index value of one underlying index is greater than its respective initial index value while the final index values of the other two underlying indices are less than their respective initial index values, but no underlying index has decreased from its respective initial index value by an amount greater than the buffer amount of 15%.
Final index value 

INDU Index: 35,000 



NDX Index: 12,350 



RTY Index: 1,980 

Index percent change 

INDU Index: (35,000 – 25,000) / 25,000 = 40% NDX Index: (12,350 – 13,000) / 13,000 = 5% RTY Index: (1,980 – 2,200) / 2,200 = 10% 

Payment at maturity 
= 
$1,000 + ($1,000 × absolute index return of the worst performing underlying index) 


= 
$1,000 + ($1,000 × 10%) 


= 
$1,100

In example 2, the final index value of the INDU Index is greater than its respective initial index value, while the final index values of the NDX Index and the RTY Index are less than their respective initial index values. The INDU Index has appreciated by 40%, the NDX Index has declined by 5% and the RTY Index has declined by 10%, but no underlying index has decreased from its respective initial index value by an amount greater than the buffer amount of 15%. Therefore, investors receive at maturity the stated principal amount plus 100% of the absolute value of the performance of the worst performing underlying index, which is the RTY Index in this example. Investors receive $1,100 per Buffered PLUS at maturity. In this example, investors receive a positive return even though two of the underlying indices have declined in value, due to the absolute return feature of the Buffered PLUS and because no underlying index has declined to below 85% of its respective initial index value.
EXAMPLE 3: The final index value of one underlying index is greater than its respective initial index value while the final index values of the other two underlying indices are less than 85% of their respective initial index values.
Final index value 

INDU Index: 27,500 



NDX Index: 5,200 



RTY Index: 1,100 

Index percent change 

INDU Index: (27,500 – 25,000) / 25,000 = 10% NDX Index: (5,200 – 13,000) / 13,000 = 60% RTY Index: (1,100 – 2,200) / 2,200 = 50% 

Index performance factor 

INDU Index: 27,500 / 25,000 = 110% NDX Index: 5,200 / 13,000 = 40% RTY Index: 1,100 / 2,200 = 50% 

Payment at maturity 
= 
($1,000 × index performance factor of the worst performing underlying index) + $150 


= 
($1,000 × 40%) + $150 


= 
$550 
In example 3, the final index value of the INDU Index is greater than its respective initial index value, while the final index values of the NDX Index and the RTY Index are less than 85% of their respective initial index values. While the INDU Index has appreciated by 10%, the NDX Index has declined by 60% and the RTY Index has declined by 50%. Therefore, investors are exposed to the negative performance of the NDX Index, which is the worst performing underlying index in this example, beyond the buffer amount of 15%, and receive a payment at maturity of $550 per Buffered PLUS. In this example, investors lose the benefit of the absolute return feature and are exposed to the negative performance of the worst performing underlying index even though one of the underlying indices has appreciated in value by 10% because the final index value of each index is not greater than or equal to 85% of its respective initial index value.
EXAMPLE 4: The final index value of each underlying index is less than its respective initial index value, but no underlying index has decreased from its respective initial index value by an amount greater than the buffer amount of 15%.
Final index value 

INDU Index: 22,500 



NDX Index: 12,350 



RTY Index: 1,936 

Index percent change 

INDU Index: (22,500 – 25,000) / 25,000 = 10% NDX Index: (12,350 – 13,000) / 13,000 = 5% RTY Index: (1,936 – 2,200) / 2,200 = 12% 

Payment at maturity 
= 
$1,000 + ($1,000 × absolute index return of the worst performing underlying index) 


= 
$1,000 + ($1,000 × 12%) 


= 
$1,120 
In example 4, the final index value of each underlying index is less than its respective initial index value, but no underlying index has decreased from its respective initial index value by an amount greater than the buffer amount of 15%. The INDU Index has declined by 10%, the NDX Index has declined by 5% and the RTY Index has declined by 12%. Therefore, investors receive at maturity the stated principal amount plus 100% of the absolute value of the performance of the worst performing underlying index, which is the RTY Index in this example. Investors receive $1,120 per Buffered PLUS at maturity.

Final index value 

INDU Index: 7,500 



NDX Index: 6,500 



RTY Index: 880

INDU Index: (7,500 – 25,000) / 25,000 = 70% NDX Index: (6,500 – 13,000) / 13,000 = 50% RTY Index: (880 – 2,200) / 2,200 = 60% 

Index performance factor 

INDU Index: 7,500 / 25,000 = 30% NDX Index: 6,500 / 13,000 = 50% RTY Index: 880 / 2,200 = 40% 

Payment at maturity 
= 
($1,000 × index performance factor of the worst performing underlying index) + $150 


= 
($1,000 × 30%) + $150 


= 
$450 
In example 5, the final index value of each underlying index is less than its respective initial index value by an amount greater than the buffer amount of 15%. The INDU Index has declined by 70%, the NDX Index has declined by 50% and the RTY Index has declined by 60%. Therefore, investors are exposed to the negative performance of the INDU Index, which is the worst performing underlying index in this example, beyond the buffer amount of 15%, and receive a payment at maturity of $450 per Buffered PLUS.
Because the payment at maturity of the Buffered PLUS is based on the worst performing of the underlying indices, a decline in any underlying index by an amount greater than the buffer amount of 15% will result in a loss, and potentially a significant loss, of your investment, even if the other underlying indices have appreciated or have not declined as much.

Risk Factors
This section describes the material risks relating to the Buffered PLUS. For further discussion of these and other risks, you should read the section entitled “Risk Factors” in the accompanying product supplement for PLUS, index supplement and prospectus. We also urge you to consult your investment, legal, tax, accounting and other advisers in connection with your investment in the Buffered PLUS.
Risks Relating to an Investment in the Buffered PLUS
￭The Buffered PLUS do not pay interest and provide a minimum payment at maturity of only 15% of the stated principal amount. The terms of the Buffered PLUS differ from those of ordinary debt securities in that the Buffered PLUS do not pay interest and provide a minimum payment at maturity of only 15% of the stated principal amount of the Buffered PLUS. If the final index value of any underlying index is less than 85% of its initial index value, the absolute return feature will no longer be available and you will instead receive for each Buffered PLUS that you hold a payment at maturity that is less than the stated principal amount of each Buffered PLUS by an amount proportionate to the decline in the value of the worst performing underlying index from its initial index value, plus $150 per Buffered PLUS. Accordingly, investors may lose up to 85% of the stated principal amount of the Buffered PLUS.
￭The market price of the Buffered PLUS will be influenced by many unpredictable factors. Several factors will influence the value of the Buffered PLUS in the secondary market and the price at which MS & Co. may be willing to purchase or sell the Buffered PLUS in the secondary market, including the value, volatility and dividend yield of the underlying indices, interest and yield rates in the market, time remaining until the Buffered PLUS mature, geopolitical conditions and economic, financial, political, regulatory or judicial events and any actual or anticipated changes in our credit ratings or credit spreads. Generally, the longer the time remaining to maturity, the more the market price of the Buffered PLUS will be affected by the other factors described above. The levels of the underlying indices may be, and have recently been, volatile, and we can give you no assurance that the volatility will lessen. See “Dow Jones Industrial AverageSM Overview,” “NASDAQ100 Index® Overview” and “Russell 2000® Index Overview” below. You may receive less, and possibly significantly less, than the stated principal amount per Buffered PLUS if you try to sell your Buffered PLUS prior to maturity.
￭The Buffered 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 Buffered PLUS. You are dependent on our ability to pay all amounts due on the Buffered PLUS at maturity and therefore you are subject to our credit risk. If we default on our obligations under the Buffered PLUS, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the Buffered PLUS prior to maturity will be affected by changes in the market’s view of our creditworthiness. Any actual or anticipated decline in our credit ratings or increase in the credit spreads charged by the market for taking our credit risk is likely to adversely affect the market value of the Buffered PLUS.
￭As a finance subsidiary, MSFL has no independent operations and will have no independent assets. As a finance subsidiary, MSFL has no independent operations beyond the issuance and administration of its securities and will have no independent assets available for distributions to holders of MSFL securities if they make claims in respect of such securities in a bankruptcy, resolution or similar proceeding. Accordingly, any recoveries by such holders will be limited to those available under the related guarantee by Morgan Stanley and that guarantee will rank pari passu with all other unsecured, unsubordinated obligations of Morgan Stanley. Holders will have recourse only to a single claim against Morgan Stanley and its assets under the guarantee. Holders of securities issued by MSFL should accordingly assume that in any such proceedings they would not have any priority over and should be treated pari passu with the claims of other unsecured, unsubordinated creditors of Morgan Stanley, including holders of Morgan Stanleyissued securities.
￭The amount payable on the Buffered PLUS is not linked to the values of the underlying indices at any time other than the valuation date. The final index value of each underlying index will be based on the index closing value of such index on the valuation date, subject to postponement for nonindex business days and certain market disruption events. Even if each underlying index appreciates prior to the valuation date but the value of any underlying index drops by the valuation date to less than 85% of its initial index value, the payment at maturity will be less than it would have been had the payment at maturity been linked to the values of the underlying indices prior to such drop. Although the actual values of the underlying indices on the stated maturity date or at other times during the term of the Buffered PLUS may be higher than their respective final index values, the payment at maturity will be based solely on the index closing values on the valuation date.
￭Investing in the Buffered PLUS is not equivalent to investing in any underlying index. Investing in the Buffered PLUS is not equivalent to investing in any underlying index or the component stocks of any underlying index. As an investor in the

Buffered PLUS, you will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to stocks that constitute the underlying indices.
￭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 Buffered PLUS in the original issue price reduce the economic terms of the Buffered PLUS, cause the estimated value of the Buffered PLUS to be less than the original issue price and will adversely affect secondary market prices. Assuming no change in market conditions or any other relevant factors, the prices, if any, at which dealers, including MS & Co., may be willing to purchase the Buffered PLUS in secondary market transactions will likely be significantly lower than the original issue price, because secondary market prices will exclude the issuing, selling, structuring and hedgingrelated costs that are included in the original issue price and borne by you and because the secondary market prices will reflect our secondary market credit spreads and the bidoffer spread that any dealer would charge in a secondary market transaction of this type as well as other factors.
The inclusion of the costs of issuing, selling, structuring and hedging the Buffered PLUS in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the Buffered PLUS less favorable to you than they otherwise would be.
However, because the costs associated with issuing, selling, structuring and hedging the Buffered PLUS are not fully deducted upon issuance, for a period of up to 6 months following the issue date, to the extent that MS & Co. may buy or sell the Buffered PLUS in the secondary market, absent changes in market conditions, including those related to the underlying indices, and to our secondary market credit spreads, it would do so based on values higher than the estimated value, and we expect that those higher values will also be reflected in your brokerage account statements.
￭The estimated value of the Buffered PLUS 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. These pricing and valuation models are proprietary and rely in part on subjective views of certain market inputs and certain assumptions about future events, which may prove to be incorrect. As a result, because there is no marketstandard way to value these types of securities, our models may yield a higher estimated value of the Buffered PLUS than those generated by others, including other dealers in the market, if they attempted to value the Buffered PLUS. In addition, the estimated value on the pricing date does not represent a minimum or maximum price at which dealers, including MS & Co., would be willing to purchase your Buffered PLUS in the secondary market (if any exists) at any time. The value of your Buffered PLUS at any time after the date of this document will vary based on many factors that cannot be predicted with accuracy, including our creditworthiness and changes in market conditions. See also “The market price of the Buffered PLUS will be influenced by many unpredictable factors” above.
￭The Buffered PLUS will not be listed on any securities exchange and secondary trading may be limited. The Buffered PLUS will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the Buffered PLUS. MS & Co. may, but is not obligated to, make a market in the Buffered PLUS and, if it once chooses to make a market, may cease doing so at any time. When it does make a market, it will generally do so for transactions of routine secondary market size at prices based on its estimate of the current value of the Buffered PLUS, taking into account its bid/offer spread, our credit spreads, market volatility, the notional size of the proposed sale, the cost of unwinding any related hedging positions, the time remaining to maturity and the likelihood that it will be able to resell the Buffered PLUS. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Buffered PLUS easily. Since other brokerdealers may not participate significantly in the secondary market for the Buffered PLUS, the price at which you may be able to trade your Buffered PLUS is likely to depend on the price, if any, at which MS & Co. is willing to transact. If, at any time, MS & Co. were to cease making a market in the Buffered PLUS, it is likely that there would be no secondary market for the Buffered PLUS. Accordingly, you should be willing to hold your Buffered PLUS to maturity.
￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the Buffered PLUS. One or more of our affiliates and/or thirdparty dealers expect to carry out hedging activities related to the Buffered PLUS (and possibly to other instruments linked to the underlying indices or their component stocks), including trading in the stocks that constitute the underlying indices as well as in other instruments related to the underlying indices. 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. Some of our affiliates also trade the stocks that constitute the underlying indices and other financial instruments related to the underlying indices on a regular basis as part of their general brokerdealer and other businesses. Any of these hedging or trading activities on or prior to the pricing date could potentially affect the initial index value of an underlying index, and, therefore, could increase the value at or above which such underlying index must close on the valuation date so that investors do not suffer a loss on their initial investment in

the Buffered PLUS (depending also on the performance of the other underlying indices). Additionally, such hedging or trading activities during the term of the Buffered PLUS, including on the valuation date, could adversely affect the closing value of an underlying index on the valuation date, and, accordingly, the amount of cash an investor will receive at maturity (depending also on the performance of the other underlying indices).
￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the Buffered PLUS. As calculation agent, MS & Co. will determine the initial index values and the final index values, including whether any underlying index has decreased to below 85% of its respective initial index value, and will calculate the amount of cash you receive at maturity. Moreover, certain determinations made by MS & Co., in its capacity as calculation agent, may require it to exercise discretion and make subjective judgments, such as with respect to the occurrence or nonoccurrence of market disruption events and the selection of a successor index or calculation of the final index value in the event of a market disruption event or discontinuance of an underlying index. These potentially subjective determinations may adversely affect the payout to you at maturity. For further information regarding these types of determinations, see “Description of PLUS—Postponement of Valuation Date(s),” “—Alternate Exchange Calculation in case of an Event of Default” and “—Calculation Agent and Calculations” and related definitions in the accompanying product supplement. In addition, MS & Co. has determined the estimated value of the Buffered PLUS on the pricing date.
￭The U.S. federal income tax consequences of an investment in the Buffered PLUS are uncertain. Please read the discussion under “Additional Information—Tax considerations” in this document and the discussion under “United States Federal Taxation” in the accompanying product supplement for PLUS (together, the “Tax Disclosure Sections”) concerning the U.S. federal income tax consequences of an investment in the Buffered PLUS. If the Internal Revenue Service (the “IRS”) were successful in asserting an alternative treatment, the timing and character of income on the Buffered PLUS might differ significantly from the tax treatment described in the Tax Disclosure Sections. For example, under one possible treatment, the IRS could seek to recharacterize the Buffered PLUS as debt instruments. In that event, U.S. Holders would be required to accrue into income original issue discount on the Buffered PLUS every year at a “comparable yield” determined at the time of issuance and recognize all income and gain in respect of the Buffered PLUS as ordinary income. The risk that financial instruments providing for buffers, triggers or similar downside protection features, such as the Buffered PLUS, would be recharacterized as debt is greater than the risk of recharacterization for comparable financial instruments that do not have such features. We do not plan to request a ruling from the IRS regarding the tax treatment of the Buffered PLUS, and the IRS or a court may not agree with the tax treatment described in the Tax Disclosure Sections.
In 2007, the U.S. Treasury Department and 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 shortterm instruments should be subject to any such accrual regime; the relevance of factors such as the exchangetraded 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 nonU.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” rule, which very generally can operate to recharacterize certain longterm capital gain as ordinary income and impose an interest charge. 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. Both U.S. and NonU.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the Buffered PLUS, including possible alternative treatments, the issues presented by this notice and any tax consequences arising under the laws of any state, local or nonU.S. taxing jurisdiction.
Risks Relating to the Underlying Indices
￭You are exposed to the price risk of each underlying index. Your return on the Buffered PLUS is not linked to a basket consisting of each underlying index. Rather, it will be based upon the independent performance of each underlying index. Unlike an instrument with a return linked to a basket of underlying assets, in which risk is mitigated and diversified among all the components of the basket, you will be exposed to the risks related to each underlying index. Poor performance by any underlying index over the term of the Buffered PLUS will negatively affect your return and will not be offset or mitigated by any positive performance by the other underlying indices. If any underlying index declines to below 85% of its respective initial index value as of the valuation date, you will lose some or a substantial portion of your investment, even if the other underlying indices have appreciated or have not declined as much. Accordingly, your investment is subject to the price risk of each underlying index.

￭Because the Buffered PLUS are linked to the performance of the worst performing underlying index, you are exposed to greater risk of sustaining a loss on your investment than if the Buffered PLUS were linked to just one underlying index. The risk that you will suffer a loss on your investment is greater if you invest in the Buffered PLUS as opposed to substantially similar securities that are linked to the performance of just one underlying index. With three underlying indices, it is more likely that any underlying index will decline to below 85% of its initial index value as of the valuation date than if the Buffered PLUS were linked to only one underlying index. Therefore it is more likely that you will suffer a loss on your investment.
￭The Buffered PLUS are linked to the Russell 2000® Index and are subject to risks associated with smallcapitalization companies. As the Russell 2000® Index is one of the underlying indices, and the Russell 2000® Index consists of stocks issued by companies with relatively small market capitalization, the Buffered PLUS are linked to the value of smallcapitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than largecapitalization companies and therefore the Russell 2000® Index may be more volatile than indices that consist of stocks issued by largecapitalization companies. Stock prices of smallcapitalization companies are also more vulnerable than those of largecapitalization companies to adverse business and economic developments, and the stocks of smallcapitalization companies may be thinly traded. In addition, small capitalization companies are typically less wellestablished and less stable financially than largecapitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Such companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and less competitive strengths than largecapitalization companies and are more susceptible to adverse developments related to their products.
￭Adjustments to the underlying indices could adversely affect the value of the Buffered PLUS. The publisher of each underlying index may add, delete or substitute the stocks constituting such underlying index or make other methodological changes that could change the value of such underlying index. The publisher of each underlying index may discontinue or suspend calculation or publication of such underlying index at any time. In these circumstances, the calculation agent will have the sole discretion to substitute a successor index that is comparable to the discontinued underlying index and will be permitted to consider indices that are calculated and published by the calculation agent or any of its affiliates.

Additional Information About the Buffered PLUS
Additional Information: 

Minimum ticketing size: 
$1,000 / 1 Buffered PLUS 
Tax considerations: 
Although there is uncertainty regarding the U.S. federal income tax consequences of an investment in the Buffered PLUS due to the lack of governing authority, in the opinion of our counsel, Davis Polk & Wardwell LLP, under current law, and based on current market conditions, a Buffered PLUS should be treated as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. However, because our counsel’s opinion is based in part on market conditions as of the date of this document, it is subject to confirmation on the pricing date.
Assuming this treatment of the Buffered PLUS is respected and subject to the discussion in “United States Federal Taxation” in the accompanying product supplement for PLUS, the following U.S. federal income tax consequences should result based on current law: ￭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. Such gain or loss should be longterm capital gain or loss if the investor has held the Buffered PLUS for more than one year, and shortterm capital gain or loss otherwise. 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 shortterm instruments should be subject to any such accrual regime; the relevance of factors such as the exchangetraded 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 nonU.S. investors should be subject to withholding tax; and whether these instruments are or should be subject to the “constructive ownership” rule, which very generally can operate to recharacterize certain longterm capital gain as ordinary income and impose an interest charge. 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 Internal Revenue Code of 1986, as amended, 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 NonU.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, 2023 that do not have a delta of one with respect to any Underlying Security. Based on the terms of the Buffered PLUS and current market conditions, we expect that the Buffered PLUS will not have a delta of one with respect to any Underlying Security on the pricing date. However, we will provide an updated determination in the final pricing supplement. Assuming 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.
