Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

The securities offered are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. The securities have the terms described in the accompanying product supplement, index supplement and prospectus, as supplemented or modified by this document. The securities do not guarantee the repayment of principal and do not provide for the regular payment of interest. Instead, the securities will pay a contingent quarterly coupon but only if the index closing value of each of the Russell 2000® Index, the Dow Jones Industrial AverageSM and the NASDAQ-100 Index® is at or above its coupon barrier level of 70% of its respective initial index value on the related observation date. If, however, the index closing value of any underlying index is less than its coupon barrier level on any observation date, we will pay no interest for the related quarterly period. In addition, the securities will be automatically redeemed if the index closing value of each underlying index is greater than or equal to its respective initial index value on any of the quarterly redemption determination dates for the early redemption payment equal to the sum of the stated principal amount plus the related contingent quarterly coupon. At maturity, if the securities have not previously been redeemed and the index closing value of each underlying index has remained greater than or equal to 70% of the respective initial index value, which we refer to as the downside threshold level, on each index business day during the term of the securities, the payment at maturity will be the stated principal amount and the related contingent quarterly coupon. If, however, the index closing value of any underlying index is less than its respective downside threshold level on any index business day during the term of the securities, a trigger event will have occurred and investors will be fully exposed to the decline in the worst performing underlying index on a 1-to-1 basis and, if the final index value of any underlying index is less than its initial index value, investors will receive a payment at maturity that is less than the stated principal amount of the securities and could be zero. Accordingly, investors in the securities must be willing to accept the risk of losing their entire initial investment and also the risk of not receiving any contingent quarterly coupons throughout the 1.5-year term of the securities. Because all payments on the securities are based on the worst performing of the underlying indices, a decline beyond the respective coupon barrier level or respective downside threshold level, as applicable, of any underlying index will result in few or no contingent coupon payments and a potentially significant loss of your investment, even if one or both of the other underlying indices have appreciated or have not declined as much. The securities are for investors who are willing to risk their principal and seek an opportunity to earn interest at a potentially above-market rate in exchange for the risk of receiving no quarterly coupons over the entire 1.5-year term. Investors will not participate in any appreciation of any underlying index. The securities are notes issued as part of MSFL’s Series A Global Medium-Term Notes program.

All payments are subject to our credit risk. If we default on our obligations, you could lose some or all of your investment. These securities 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.

Contingent Income Auto-Callable Securities due July 31, 2023 All Payments on the Securities Based on the Worst Performing of the Russell 2000® Index, Dow Jones Industrial AverageSM and the NASDAQ-100 Index® (the “securities”) do not provide for the regular payment of interest. Instead, the securities will pay a contingent quarterly coupon but only if the index closing value of each underlying index is at or above 70% of its initial index value, which we refer to as the respective coupon barrier level, on the related observation date. If the index closing value of any underlying index is less than the respective coupon barrier level on any observation date, we will pay no coupon for the related quarterly period. It is possible that the index closing value of any underlying index could remain below the respective coupon barrier level for extended periods of time or even throughout the entire 1.5-year term of the securities so that you will receive few or no contingent quarterly coupons during the term of the securities. We refer to these coupons as contingent, because there is no guarantee that you will receive a coupon payment on any coupon payment date. Even if all underlying indices were to be at or above their respective coupon barrier levels on some quarterly observation dates, one or more underlying indices may fluctuate below the respective coupon barrier level(s) on others. In addition, if the securities have not been automatically called prior to maturity and the index closing value of any underlying index is less than 70% of the respective initial index value, which we refer to as the downside threshold level, on any index business day during the term of the securities, a trigger event will have occurred and investors will be fully exposed to the decline in the worst performing underlying index on a 1-to-1 basis and, if the final index value of any underlying index is less than its initial index value, investors will receive a payment at maturity that is less than the stated principal amount of the securities and could be zero. Investors will not participate in any appreciation of any underlying index. Accordingly, investors in the securities must be willing to accept the risk of losing their entire initial investment and also the risk of not receiving any contingent quarterly coupons throughout the entire 1.5-year term of the securities.

Principal at Risk Securities

The original issue price of each security is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the securities, which are borne by you, and, consequently, the estimated value of the securities on the pricing date will be less than $1,000. We estimate that the value of each security on the pricing date will be approximately $962.20, or within $25.00 of that estimate. Our estimate of the value of the securities 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 securities on the pricing date, we take into account that the securities comprise both a debt component and a performance-based component linked to the underlying indices. The estimated value of the securities 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 securities?

In determining the economic terms of the securities, including the contingent quarterly coupon rate, the coupon barrier levels and the downside threshold levels, 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 securities 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 securities?

The price at which MS & Co. purchases the securities 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 bid-offer 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 securities are not fully deducted upon issuance, for a period of up to 4 months following the issue date, to the extent that MS & Co. may buy or sell the securities 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 securities and, if it once chooses to make a market, may cease doing so at any time.

Key Investment Rationale

The securities do not provide for the regular payment of interest. Instead, the securities will pay a contingent quarterly coupon but only if the index closing value of each underlying index is at or above its respective coupon barrier level on the related observation date. The securities have been designed for investors who are willing to forgo market floating interest rates and accept the risk of receiving no coupon payments for the entire 1.5-year term of the securities in exchange for an opportunity to earn interest at a potentially above market rate if each underlying index closes at or above its respective coupon barrier level on each quarterly observation date until the securities are redeemed early or reach maturity. The following scenarios are for illustrative purposes only to demonstrate how the coupon and the payment at maturity (if the securities have not previously been redeemed) are calculated, and do not attempt to demonstrate every situation that may occur. Accordingly, the securities may or may not be redeemed, the contingent coupon may be payable in none of, or some but not all of, the quarterly periods during the 1.5-year term of the securities and the payment at maturity may be less than the stated principal amount of the securities and may be zero.

Hypothetical Examples

The following hypothetical examples illustrate how to determine whether a contingent quarterly coupon is paid with respect to an observation date and how to calculate the payment at maturity if the securities have not been automatically redeemed early. The following examples are for illustrative purposes only. Whether you receive a contingent quarterly coupon will be determined by reference to the index closing value of each underlying index on each quarterly observation date, and the amount you will receive at maturity, if any, will be determined by reference to the index closing value of each underlying index throughout the term of the securities. The actual initial index value, coupon barrier level and downside threshold level for each underlying index will be determined on the pricing date. All payments on the securities, if any, are subject to our credit risk. The numbers in the hypothetical examples below may have been rounded for the ease of analysis. The below examples are based on the following terms:

* The actual contingent quarterly coupon will be an amount determined by the calculation agent based on the actual contingent quarterly coupon rate and the number of days in the applicable payment period, calculated on a 30/360 day-count basis. The hypothetical contingent quarterly coupon of $21.875 is used in these examples for ease of analysis.

Principal at Risk Securities

How to determine whether a contingent quarterly coupon is payable with respect to an observation date:

On hypothetical observation date 1, the RTY Index, the INDU Index and the NDX Index all close at or above their respective coupon barrier levels. Therefore a contingent quarterly coupon of $21.875 is paid on the relevant coupon payment date.

On each of the hypothetical observation dates 2 and 3, two underlying indices close at or above their respective coupon barrier levels, but the other underlying index closes below its coupon barrier level. Therefore, no contingent quarterly coupon is paid on the relevant coupon payment date.

On hypothetical observation date 4, each underlying index closes below its respective coupon barrier level, and, accordingly, no contingent quarterly coupon is paid on the relevant coupon payment date.

You will not receive a contingent quarterly coupon on any coupon payment date if the closing level of any underlying index is below its respective coupon barrier level on the related observation date.

How to calculate the payment at maturity (if the securities have not been automatically redeemed early):

Example 1: A trigger event HAS NOT occurred.

In example 1, the index closing values of the RTY Index, the INDU Index and the NDX Index are all at or above their respective downside threshold levels on each index business day during the term of the securities. Therefore, a trigger event has not occurred and investors receive at maturity the stated principal amount of the securities and the contingent quarterly coupon with respect to the final observation date. However, investors do not participate in any appreciation of any underlying index.

Example 2: A trigger event HAS occurred.

Contingent Income Auto-Callable Securities due July 31, 2023

All Payments on the Securities Based on the Worst Performing of the Russell 2000® Index, the Dow Jones Industrial AverageSM and the NASDAQ-100 Index®

Principal at Risk Securities

In example 2, the index closing values of two underlying indices are at or above their respective downside threshold levels on each index business day during the term of the securities, but the index closing value of the other underlying index is below its downside threshold level on one or more index business days during the term of the securities. The final index values of the RTY Index, the INDU Index and the NDX Index are at or above the respective coupon barrier levels on the final observation date. However, because a trigger event has occurred, investors are exposed to the downside performance of the worst performing underlying index at maturity, even though two of the underlying indices have appreciated. Because the final index value of each underlying index is greater than its respective coupon barrier level, investors receive the contingent quarterly coupon with respect to the final observation date. The payment at maturity is an amount equal to the contingent quarterly coupon with respect to the final observation date plus (i) the stated principal amount times (ii) the index performance factor of the worst performing underlying index.

Example 3: A trigger event HAS occurred.

In example 3, the index closing values of the RTY Index, the INDU Index and the NDX Index are all below the respective downside threshold levels on one or more index business days during the term of the securities. Therefore, a trigger event has occurred, and investors are exposed to the downside performance of the worst performing underlying index at maturity. Because the final index value of one or more of the underlying indices are below the respective coupon barrier levels, investors do not receive the contingent quarterly coupon with respect to the final observation date. The payment at maturity is an amount equal to the stated principal amount times the index performance factor of the worst performing underlying index.

If a trigger event occurs on any index business day during the term of the securities, investors will have full downside exposure to the worst performing underlying index at maturity. Under these circumstances, if the final index value of any underlying index is less than its respective initial index value, investors will lose some or all of their investment in the securities.

Risk Factors

This section describes the material risks relating to the securities. For further discussion of these and other risks, you should read the section entitled “Risk Factors” in the accompanying product supplement, index supplement and prospectus. We also urge you to consult with your investment, legal, tax, accounting and other advisers in connection with your investment in the securities.

Risks Relating to an Investment in the Securities

￭The securities do not guarantee the return of any principal. The terms of the securities differ from those of ordinary debt securities in that they do not guarantee the repayment of any principal. If the securities have not been automatically redeemed prior to maturity and the index closing value of any underlying index is less than its respective downside threshold level on any index business day during the term of the securities, a trigger event will have occurred and you will be exposed to the decline in the closing value of the worst performing underlying index, as compared to its initial index value, on a 1-to-1 basis at maturity. If a trigger event occurs on any index business day during the term of the securities, investors will have full downside exposure to the worst performing underlying index at maturity. Under these circumstances, if the final index value of any underlying index is less than its respective initial index value, investors will lose some or all of their investment in the securities. In this case, you will receive for each security that you hold at maturity an amount equal to the stated principal amount times the index performance factor of the worst performing underlying index, subject to a maximum payment at maturity of the stated principal amount. In this case, the payment at maturity will be less than the stated principal amount and could be zero.

￭The securities do not provide for the regular payment of interest. The terms of the securities differ from those of ordinary debt securities in that they do not provide for the regular payment of interest. Instead, the securities will pay a contingent quarterly coupon but only if the index closing value of each underlying index is at or above 70% of its respective initial index value, which we refer to as the coupon barrier level, on the related observation date. If, on the other hand, the index closing value of any underlying index is lower than the coupon barrier level for such underlying index on the relevant observation date for any interest period, we will pay no coupon on the applicable coupon payment date. Moreover, in such a case, a trigger event will necessarily have occurred, and you will have full downside exposure to the worst performing underlying index at maturity. It is possible that the index closing value of one or more underlying indices will remain below the respective coupon barrier level(s) for extended periods of time or even throughout the entire 1.5-year term of the securities so that you will receive few or no contingent quarterly coupons. If you do not earn sufficient contingent quarterly coupons over the term of the securities, the overall return on the securities may be less than the amount that would be paid on a conventional debt security of ours of comparable maturity.

￭The contingent quarterly coupon, if any, is based on the value of each underlying index on only the related quarterly observation date at the end of the related interest period. Whether the contingent quarterly coupon will be paid on any coupon payment date will be determined at the end of the relevant interest period based on the closing value of each underlying index on the relevant quarterly observation date. As a result, you will not know whether you will receive the contingent quarterly coupon on any coupon payment date until near the end of the relevant interest period. Moreover, because the contingent quarterly coupon is based solely on the value of each underlying index on quarterly observation dates, if the closing value of any underlying index on any observation date is below the coupon barrier level for such index, you will receive no coupon for the related interest period, even if the level of such underlying index was at or above its respective coupon barrier level on other days during that interest period and even if the closing value of the other underlying indices are at or above the coupon barrier levels for such indices.

￭Investors will not participate in any appreciation in any underlying index. Regardless of whether or not a trigger event occurs, investors will not participate in any appreciation in any underlying index from the initial index value for such index, and the return on the securities will be limited to the contingent quarterly coupons, if any, that are paid with respect to each observation date on which the index closing value of each underlying index is greater than or equal to its respective coupon barrier level.

￭The market price will be influenced by many unpredictable factors. Several factors, many of which are beyond our control, will influence the value of the securities in the secondary market and the price at which MS & Co. may be willing to purchase or sell the securities in the secondary market. We expect that generally the level of interest rates available

Principal at Risk Securities

in the market and the value of each underlying index on any index business day, including in relation to its respective coupon barrier level and downside threshold level, will affect the value of the securities more than any other factors. Other factors that may influence the value of the securities include:

othe volatility (frequency and magnitude of changes in value) of the underlying indices,

owhether a trigger event has occurred on any index business day during the term of the securities,

owhether the index closing value of any underlying index has been below its respective coupon barrier level on any observation date,

ogeopolitical conditions and economic, financial, political, regulatory or judicial events that affect the component stocks of the underlying indices or securities markets generally and which may affect the value of each underlying index,

odividend rates on the securities underlying the underlying indices,

othe time remaining until the securities mature,

ointerest and yield rates in the market,

othe availability of comparable instruments,

othe composition of the underlying indices and changes in the constituent stocks of such indices, and

oany actual or anticipated changes in our credit ratings or credit spreads.

Some or all of these factors will influence the price that you will receive if you sell your securities prior to maturity. In particular, if any underlying index has closed near or below its coupon barrier level and downside threshold level, the market value of the securities is expected to decrease substantially, and you may have to sell your securities at a substantial discount from the stated principal amount of $1,000 per security.

You cannot predict the future performance of any underlying index based on its historical performance. The value of any underlying index may decrease and be below the coupon barrier level for such index on each observation date so that you will receive no return on your investment, and one or more underlying indices may close below the respective downside threshold level(s) on any index business day during the term of the securities so that you are exposed to the negative performance of the worst performing underlying index at maturity. There can be no assurance that the index closing value of each underlying index will be at or above the respective coupon barrier level on any observation date so that you will receive a coupon payment on the securities for the applicable interest period, or that it will be at or above its respective downside threshold level on each index business day during the term of the securities so that you do not suffer a loss on your initial investment in the securities. See “Russell 2000® Index Overview,” “Dow Jones Industrial AverageSM Overview” and “NASDAQ-100 Index® Overview” below.

￭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. You are dependent on our ability to pay all amounts due on the securities at maturity, upon early redemption or on any coupon payment date, and therefore you are subject to our credit risk. The securities are not guaranteed by any other entity. If we default on our obligations under the securities, your investment would be at risk and you could lose some or all of your investment. As a result, the market value of the securities 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 securities.

￭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

Principal at Risk Securities

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 Stanley-issued securities.

￭Not equivalent to investing in the underlying indices. Investing in the securities is not equivalent to investing in any underlying index or the component stocks of any underlying index. Investors in the securities will not participate in any positive performance of any underlying index, and will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to stocks that constitute any underlying index.

￭Reinvestment risk. The term of your investment in the securities may be shortened due to the automatic early redemption feature of the securities. If the securities are redeemed prior to maturity, you will receive no more contingent quarterly coupons and may be forced to invest in a lower interest rate environment and may not be able to reinvest at comparable terms or returns.

￭The securities will not be listed on any securities exchange and secondary trading may be limited. Accordingly, you should be willing to hold your securities for the entire 1.5-year term of the securities. The securities will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the securities. MS & Co. may, but is not obligated to, make a market in the securities 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 securities, 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 securities. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the securities easily. Since other broker-dealers may not participate significantly in the secondary market for the securities, the price at which you may be able to trade your securities 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 securities, it is likely that there would be no secondary market for the securities. Accordingly, you should be willing to hold your securities to maturity.

￭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. 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 securities 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 hedging-related 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 bid-offer 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 securities in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the securities less favorable to you than they otherwise would be.

However, because the costs associated with issuing, selling, structuring and hedging the securities are not fully deducted upon issuance, for a period of up to 4 months following the issue date, to the extent that MS & Co. may buy or sell the securities 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 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. 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 market-standard way to value these types of securities, our models may yield a higher estimated value of the securities than those

generated by others, including other dealers in the market, if they attempted to value the securities. 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 securities in the secondary market (if any exists) at any time. The value of your securities 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.

￭Hedging and trading activity by our affiliates could potentially affect the value of the securities. One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the securities (and 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 securities, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the final observation 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 broker-dealer and other businesses. Any of these hedging or trading activities on or prior to the pricing date could potentially increase the initial index value of an underlying index, and, therefore, could increase (i) the value at or above which such underlying index must close on the redemption determination dates so that the securities are redeemed prior to maturity for the early redemption payment (depending also on the performance of the other underlying indices), (ii) the coupon barrier level for such underlying index, which is the value at or above which such underlying index must close on the observation dates in order for you to earn a contingent quarterly coupon (depending also on the performance of the other underlying indices) and (iii) the downside threshold level for such underlying index, which is the value at or above which such underlying index must close on each index business day during the term of the securities so that you are not exposed to the negative performance of the worst performing underlying index at maturity (depending also on the performance of the other underlying indices). Additionally, such hedging or trading activities during the term of the securities could affect the value of an underlying index throughout the term of the securities, and, accordingly, whether we redeem the securities prior to maturity, whether we pay a contingent quarterly coupon on the securities and the amount of cash you receive at maturity, if any (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 securities. As calculation agent, MS & Co. will determine the initial index value, the coupon barrier level and the downside threshold level for each underlying index, whether you receive a contingent quarterly coupon on each coupon payment date and/or at maturity, whether the securities will be redeemed on any early redemption date, whether a trigger event has occurred and the payment at maturity, if any. 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 non-occurrence of market disruption events and the selection of a successor index or calculation of the index closing 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, if any. For further information regarding these types of determinations, see "Description of Auto-Callable Securities—Postponement of Determination Dates," "—Alternate Exchange Calculation in Case of an Event of Default,” "—Discontinuance of Any Underlying Index; Alteration of Method of Calculation” and "—Calculation Agent and Calculations" in the accompanying product supplement. In addition, MS & Co. has determined the estimated value of the securities on the pricing date.

￭The U.S. federal income tax consequences of an investment in the securities are uncertain. There is no direct legal authority as to the proper treatment of the securities for U.S. federal income tax purposes, and, therefore, significant aspects of the tax treatment of the securities are uncertain.

Please read the discussion under “Additional Information—Tax considerations” in this document concerning the U.S. federal income tax consequences of an investment in the securities. We intend to treat a security for U.S. federal income tax purposes as a single financial contract that provides for a coupon that will be treated as gross income to you at the time received or accrued, in accordance with your regular method of tax accounting. Under this treatment, the ordinary income treatment of the coupon payments, in conjunction with the capital loss treatment of any loss recognized upon the sale, exchange or settlement of the securities, could result in adverse tax consequences to holders of the

securities because the deductibility of capital losses is subject to limitations. We do not plan to request a ruling from the Internal Revenue Service (the “IRS”) regarding the tax treatment of the securities, and the IRS or a court may not agree with the tax treatment described herein. If the IRS were successful in asserting an alternative treatment for the securities, the timing and character of income or loss on the securities might differ significantly from the tax treatment described herein. For example, under one possible treatment, the IRS could seek to recharacterize the securities as debt instruments. In that event, U.S. Holders (as defined below) would be required to accrue into income original issue discount on the securities every year at a “comparable yield” determined at the time of issuance (as adjusted based on the difference, if any, between the actual and the projected amount of any contingent payments on the securities) and recognize all income and gain in respect of the securities as ordinary income. The risk that financial instruments providing for buffers, triggers or similar downside protection features, such as the securities, would be recharacterized as debt is greater than the risk of recharacterization for comparable financial instruments that do not have such features.

Non-U.S. Holders (as defined below) should note that we currently intend to withhold on any coupon paid to Non-U.S. Holders generally at a rate of 30%, or at a reduced rate specified by an applicable income tax treaty under an “other income” or similar provision, and will not be required to pay any additional amounts with respect to amounts withheld.

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. While it is not clear whether the securities would be viewed as similar to the prepaid forward contracts described in the notice, it is possible that 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 securities, possibly with retroactive effect. The notice focuses on a number of issues, the most relevant of which for holders of the securities are the character and timing of income or loss and the degree, if any, to which income realized by non-U.S. investors should be subject to withholding tax. Both U.S. and Non-U.S. Holders should consult their tax advisers regarding the U.S. federal income tax consequences of an investment in the securities, including possible alternative treatments, the issues presented by this notice and any tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

Risks Relating to the Underlying Indices

￭You are exposed to the price risk of all three underlying indices, with respect to both the contingent quarterly coupons, if any, and the payment at maturity, if any. Your return on the securities is not linked to a basket consisting of all three underlying indices. Rather, it will be contingent 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 all three underlying indices. Poor performance by any underlying index over the term of the securities will negatively affect your return and will not be offset or mitigated by any positive performance by the other underlying indices. To receive any contingent quarterly coupons, each underlying index must close at or above its respective coupon barrier level on the applicable observation date. In addition, if the securities have not been automatically redeemed early and the index closing value of any underlying index is less than its respective downside threshold level on any index business day during the term of the securities, a trigger event will have occurred and you will be fully exposed to the decline in the worst performing underlying index over the term of the securities on a 1-to-1 basis, even if the other underlying indices have appreciated or have not declined as much, and even if the worst performing underlying index is not the underlying index that originally caused the occurrence of the trigger event. Under this scenario, the value of any such payment will be less than the stated principal amount and could be zero. Accordingly, your investment is subject to the price risk of all three underlying indices.

￭Because the securities are linked to the performance of the worst performing underlying index, you are exposed to greater risks of receiving no contingent quarterly coupons and sustaining a significant loss on your investment than if the securities were linked to just one index. The risk that you will not receive any contingent quarterly coupons, or that you will suffer a loss on your investment, is greater if you invest in the securities 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 close below its coupon barrier level on any observation date, or

below its downside threshold level on any index business day during the term of the securities, which would constitute a trigger event, than if the securities were linked to only one underlying index. Therefore, it is more likely that you will not receive any contingent quarterly coupons and that you will suffer a loss on your investment. In addition, because each underlying index must close above its initial index value on a quarterly determination date in order for the securities to be called prior to maturity, the securities are less likely to be called on any redemption determination date than if the securities were linked to just one underlying index.

￭The securities are linked to the Russell 2000® Index and are subject to risks associated with small-capitalization 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 securities are linked to the value of small-capitalization companies.  These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the Russell 2000® Index may be more volatile than indices that consist of stocks issued by large-capitalization companies.  Stock prices of small-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business and economic developments, and the stocks of small-capitalization companies may be thinly traded.  In addition, small capitalization companies are typically less well-established and less stable financially than large-capitalization 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 large-capitalization companies and are more susceptible to adverse developments related to their products.

￭Adjustments to the underlying indices could adversely affect the value of the securities. The publisher of each underlying index may add, delete or substitute the component stocks of such underlying index or make other methodological changes that could change the value of such underlying index. Any of these actions could adversely affect the value of the securities. The publisher of each underlying index may also discontinue or suspend calculation or publication of such underlying index at any time. In these circumstances, MS & Co., as the calculation agent, will have the sole discretion to substitute a successor index that is comparable to the discontinued index. MS & Co. could have an economic interest that is different than that of investors in the securities insofar as, for example, MS & Co. is permitted to consider indices that are calculated and published by MS & Co. or any of its affiliates. If MS & Co. determines that there is no appropriate successor index on any relevant date of calculation, the determination of whether a contingent quarterly coupon will be payable on the securities on the applicable coupon payment date, and/or the amount payable at maturity, will be based on the value of such underlying index, based on the closing prices of the stocks constituting such underlying index at the time of such discontinuance, without rebalancing or substitution, computed by MS & Co. as calculation agent in accordance with the formula for calculating such underlying index last in effect prior to such discontinuance, as compared to the coupon barrier level or downside threshold level, as applicable (depending also on the performance of the other underlying indices).
