Trigger PLUS Based on the Value of the Worst Performing of the S&P 500® Futures Excess Return Index and the S&P MidCap 400® Index due December 23, 2027

Trigger Performance Leveraged Upside SecuritiesSM

Fully and Unconditionally Guaranteed by Morgan Stanley

Principal at Risk Securities

The Trigger PLUS are unsecured obligations of Morgan Stanley Finance LLC (“MSFL”) and are fully and unconditionally guaranteed by Morgan Stanley. The Trigger PLUS will pay no interest, do not guarantee any return of principal at maturity 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 Trigger PLUS will be based on the value of the worst performing of the S&P 500® Futures Excess Return Index and the S&P MidCap 400® Index, which we refer to as the underlying indices. At maturity, if both underlying indices have appreciated in value, investors will receive the stated principal amount of their investment plus leveraged upside performance of the worst performing underlying index. If either of the underlying indices depreciates in value, but the final index value of each underlying index is greater than or equal to 80% of the respective initial index value, which we refer to as the respective trigger level, investors will receive the stated principal amount of their investment. However, if the final index value of either underlying index is less than its respective trigger level, investors will lose a significant portion or all of their investment, resulting in a loss of 1% for every 1% decline in the worst performing underlying index from its initial index value. Investors may lose their entire initial investment in the Trigger PLUS. Because the payment at maturity of the Trigger PLUS is based on the worst performing of the underlying indices, a decline in either underlying index below its respective trigger level will result in a significant loss of your investment, even if the other underlying index has appreciated or has not declined as much. The Trigger PLUS are for investors who seek an equity index-based return and who are willing to risk their principal, risk exposure to the worst performing of two underlying indices and forgo current income in exchange for the upside leverage feature and the limited protection against loss that applies only if the final index value of each underlying index is greater than or equal to the respective trigger level. The Trigger PLUS are notes issued as part of MSFL’s Series A Global Medium-Term Notes program.

The S&P 500® Futures Excess Return Index measures the performance of the nearest maturing quarterly E-mini S&P 500 futures contract (the “futures contract”) trading on the Chicago Mercantile Exchange (the “CME”). The futures contract references the S&P 500® Index (the “reference index”). For more information about the S&P 500® Index, see the accompanying index supplement. For more information about the S&P 500® Futures Excess Return Index, see “Annex A — S&P 500® Futures Excess Return Index” beginning on page 18.

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

(1)The Trigger PLUS will be sold only to investors purchasing the Trigger PLUS in fee-based advisory accounts.

(2)MS & Co. expects to sell all of the Trigger PLUS that it purchases from us to an unaffiliated dealer at a price of $992.50 per Trigger PLUS, for further sale to certain fee-based advisory accounts at the price to public of $1,000 per Trigger PLUS. MS & Co. will not receive a sales commission with respect to the Trigger PLUS.

Investment Summary

Performance Leveraged Upside Securities

The Trigger PLUS Based on the Value of the Worst Performing of the S&P 500® Futures Excess Return Index and the S&P MidCap 400® Index due December 23, 2027 (the “Trigger PLUS”) can be used:

￭As an alternative to direct exposure to the underlying indices that enhances returns for any positive performance of the worst performing underlying index.

￭To potentially outperform the worst performing of the S&P 500® Futures Excess Return Index and the S&P MidCap 400® Index by taking advantage of the leverage factor, with no limitation on the appreciation potential.

￭To provide limited protection against loss of principal in the event of a decline of the underlying indices but only if the respective final index level of the worst performing underlying index is greater than or equal to the respective trigger level.

The original issue price of each Trigger PLUS is $1,000. This price includes costs associated with issuing, selling, structuring and hedging the Trigger PLUS, which are borne by you, and, consequently, the estimated value of the Trigger PLUS on the pricing date is less than $1,000. We estimate that the value of each Trigger PLUS on the pricing date is $972.40.

What goes into the estimated value on the pricing date?

In valuing the Trigger PLUS on the pricing date, we take into account that the Trigger PLUS comprise both a debt component and a performance-based component linked to the underlying indices. The estimated value of the Trigger 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 Trigger PLUS?

In determining the economic terms of the Trigger PLUS, including the leverage factor and the trigger 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 Trigger 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 Trigger PLUS?

The price at which MS & Co. purchases the Trigger 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 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 Trigger 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 Trigger 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 Trigger PLUS, and, if it once chooses to make a market, may cease doing so at any time.

Key Investment Rationale

The Trigger PLUS offer leveraged upside exposure to the worst performing of the S&P 500® Futures Excess Return Index and the S&P MidCap 400® Index. In exchange for the leverage feature, investors are exposed to the risk of loss of a significant portion or all of their investment due to the trigger feature. At maturity, an investor will receive an amount in cash based upon the closing value of the worst performing underlying index on the valuation date. The Trigger PLUS are unsecured obligations of ours, and all payments on the Trigger PLUS are subject to our credit risk. Investors may lose their entire initial investment in the Trigger PLUS.

Hypothetical Examples

The following hypothetical examples illustrate how to calculate the payment at maturity on the Trigger PLUS. The following examples are for illustrative purposes only. The actual initial index value and trigger level for each underlying index are set forth on the cover of this document. The payment at maturity on the Trigger PLUS is subject to our credit risk. The below examples are based on the following terms:

EXAMPLE 1: Both underlying indices appreciate over the term of the Trigger PLUS, and investors receive the stated principal amount plus the leveraged upside payment, calculated based on the index percent change of the worst performing underlying index.

In example 1, the final index values of both the SPXFP Index and the MID Index are greater than their initial index values. The SPXFP Index has appreciated by 10%, while the MID Index has appreciated by 50%. Therefore, investors receive at maturity the stated principal amount plus 212% of the appreciation of the worst performing underlying index, which is the SPXFP Index in this example. Investors receive $1,212 per Trigger PLUS at maturity.

EXAMPLE 2: One underlying index appreciates, while the other declines over the term of the Trigger PLUS but neither index declines below the respective trigger level, and investors receive the stated principal amount.

In example 2, the final index value of the SPXFP Index is greater than its initial index value, while the final index value of the MID Index is less than its initial index value, but is greater than or equal to the respective trigger level. The SPXFP Index has appreciated by 30% while the MID Index has declined by 15%. Investors will receive the stated principal amount of $1,000.

EXAMPLE 3: One underlying index appreciates while the other declines over the term of the Trigger PLUS, and the final index value of the worst performing underlying index is less than the respective trigger level. Investors are therefore exposed to the decline in the worst performing underlying index from its initial index value.

In example 3, the final index value of the SPXFP Index is greater than its initial index value, while the final index value of the MID Index has declined below the trigger level. The SPXFP Index has appreciated by 30% while the MID Index has depreciated by 70%. Because the final index value of the MID Index has declined below the trigger level, investors are exposed to the negative performance of the MID Index, which is the worst performing underlying index in this example. Investors receive a payment at maturity of $300.

EXAMPLE 4: Both underlying indices decline below their respective trigger levels, and investors are therefore exposed to the decline in the worst performing underlying index from its initial index value.

In example 4, the final index values of both the SPXFP Index and the MID Index are less than their respective trigger levels. The SPXFP Index has declined by 70% while the MID Index has declined by 65%. Therefore, investors are exposed to the negative performance of the SPXFP Index, which is the worst performing underlying index in this example. Investors receive a payment at maturity of $300.

Because the payment at maturity of the Trigger PLUS is based on the worst performing of the underlying indices, a decline in either underlying index below its respective trigger level will result in a significant loss of your investment, even if the other underlying index has appreciated or has not declined as much.

Risk Factors

This section describes the material risks relating to the Trigger 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 Trigger PLUS.

Risks Relating to an Investment in the Trigger PLUS

￭The Trigger PLUS do not pay interest or guarantee return of any principal. The terms of the Trigger PLUS differ from those of ordinary debt securities in that the Trigger PLUS do not pay interest or guarantee payment of any principal at maturity. If the final index value of either underlying index is less than the respective trigger level (which is 80% of the respective initial index level), the payout at maturity will be an amount in cash that is at least 20% less than the $1,000 stated principal amount of each Trigger PLUS, and this decrease will be by an amount proportionate to the full decrease in the value of the worst performing underlying index over the term of the Trigger PLUS. There is no minimum payment at maturity on the Trigger PLUS, and you could lose your entire investment.

￭The market price will be influenced by many unpredictable factors. Several factors will influence the value of the Trigger PLUS in the secondary market and the price at which MS & Co. may be willing to purchase or sell the Trigger PLUS in the secondary market, including the value, volatility and dividend yield of the underlying indices or the reference index, interest and yield rates, time remaining to maturity, geopolitical conditions and economic, financial, political, regulatory or judicial events that affect the futures contract included in the SPXFP Index, its reference index, the component stocks of the MID Index or the reference index or securities markets generally and which may affect the value of underlying indices, 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 Trigger PLUS will be affected by the other factors described above. The levels of the underlying indices may be, and have recently been, extremely volatile, and we can give you no assurance that the volatility will lessen.  See “S&P 500® Futures Excess Return Index Overview” and “S&P MidCap 400® Index Overview” below.  You may receive less, and possibly significantly less, than the stated principal amount per Trigger PLUS if you try to sell your Trigger PLUS prior to maturity.

￭The Trigger 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 Trigger PLUS. You are dependent on our ability to pay all amounts due on the Trigger PLUS at maturity and therefore you are subject to our credit risk. If we default on our obligations under the Trigger 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 Trigger 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 Trigger 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 Stanley-issued securities.

￭The amount payable on the Trigger 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 adjustment for non-index business days and certain market disruption events. Even if both underlying indices appreciate prior to the valuation date but the value of either underlying index drops by the valuation date to below its trigger level, the payment at maturity will be significantly 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 Trigger 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 Trigger PLUS is not equivalent to investing in either underlying index. Investing in the Trigger PLUS is not equivalent to investing in either underlying index, the futures contract included in the SPXFP Index or the component stocks of the MID Index or the reference index. Investors in the Trigger PLUS will not have voting rights or rights to receive dividends or other distributions or any other rights with respect to stocks that constitute either underlying index or the component stocks of the reference index. Further, by purchasing the Trigger PLUS, you are taking credit risk to us and not to any counter-party to the

futures contract linked to the SPXFP Index. Your return on the Trigger PLUS will not reflect the return you would realize if you purchased any stocks or futures contracts that are tracked directly or indirectly by 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 Trigger PLUS in the original issue price reduce the economic terms of the Trigger PLUS, cause the estimated value of the Trigger 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 Trigger 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 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 Trigger PLUS in the original issue price and the lower rate we are willing to pay as issuer make the economic terms of the Trigger PLUS less favorable to you than they otherwise would be.

However, because the costs associated with issuing, selling, structuring and hedging the Trigger 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 Trigger 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 Trigger PLUS will not be listed on any securities exchange and secondary trading may be limited. The Trigger PLUS will not be listed on any securities exchange. Therefore, there may be little or no secondary market for the Trigger PLUS. MS & Co. may, but is not obligated to, make a market in the Trigger PLUS. Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Trigger PLUS easily. Because we do not expect that other broker-dealers will participate significantly in the secondary market for the Trigger PLUS, the price at which you may be able to trade your Trigger 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 not to make a market in the Trigger PLUS, it is likely that there would be no secondary market for the Trigger PLUS. Accordingly, you should be willing to hold your Trigger PLUS to maturity.

￭The estimated value of the Trigger 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 market-standard way to value these types of securities, our models may yield a higher estimated value of the Trigger PLUS than those generated by others, including other dealers in the market, if they attempted to value the Trigger 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 Trigger PLUS in the secondary market (if any exists) at any time. The value of your Trigger 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 will be influenced by many unpredictable factors” above.

￭Hedging and trading activity by our affiliates could potentially adversely affect the value of the Trigger PLUS. One or more of our affiliates and/or third-party dealers expect to carry out hedging activities related to the Trigger PLUS (and to other instruments linked to the underlying its indices, the futures contract included in the SPXFP Index or the component stocks of the MID Index or the reference index), including trading in the futures contract included in the SPXFP Index, the stocks that constitute the MID Index and the reference index 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 Trigger PLUS, and the hedging strategy may involve greater and more frequent dynamic adjustments to the hedge as the valuation date approaches. MS & Co. and some of our other affiliates also trade the stocks that constitute the MID Index and the reference index 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 the trigger level for such underlying index, which is the level at or above which such underlying index must close on the valuation date so that investors do not suffer a significant loss on their initial investment in the Trigger PLUS (depending also on the performance of the other underlying index). Additionally, such hedging or trading activities during the term of the Trigger PLUS, including on the valuation date, could potentially affect whether the value of an underlying index on the valuation date is below the respective trigger level, and, therefore, whether an investor would receive significantly less than the stated principal amount of the Trigger PLUS at maturity (depending also on the performance of the other underlying index).

￭The calculation agent, which is a subsidiary of Morgan Stanley and an affiliate of MSFL, will make determinations with respect to the Trigger PLUS. As calculation agent, MS & Co. will determine the initial index values, the trigger levels and the final index values, including whether either underlying index has decreased to below the respective trigger level, and will calculate the amount of cash, if any, you will 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 non-occurrence 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 the underlying indices. 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 PLUS—Postponement of Valuation Date(s)” and “—Calculation Agent and Calculations” and related definitions in the accompanying product supplement. In addition, MS & Co. has determined the estimated value of the Trigger PLUS on the pricing date.

￭The U.S. federal income tax consequences of an investment in the Trigger 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 Trigger PLUS. There is no direct legal authority regarding the proper U.S. federal tax treatment of the Trigger PLUS, and we do not plan to request a ruling from the Internal Revenue Service (the “IRS”). Consequently, significant aspects of the tax treatment of the Trigger PLUS are uncertain, and the IRS or a court might not agree with the tax treatment of a Trigger PLUS as a single financial contract that is an “open transaction” for U.S. federal income tax purposes. If the IRS were successful in asserting an alternative treatment of the Trigger PLUS, the tax consequences of the ownership and disposition of the Trigger PLUS, including the timing and character of income recognized by U.S. Holders and the withholding tax consequences to Non-U.S. Holders, might be materially and adversely affected. Moreover, future legislation, Treasury regulations or IRS guidance could adversely affect the U.S. federal tax treatment of the Trigger PLUS, possibly retroactively.

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 Trigger PLUS, including possible alternative treatments, as well as 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 both underlying indices. Your return on the Trigger PLUS it not linked to a basket consisting of both underlying indices. 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 both underlying indices. Poor performance by either underlying index over the term of the Trigger PLUS will negatively affect your return and will not be offset or mitigated by any positive performance by the other underlying index. If either underlying index declines to below its respective trigger level as of the valuation date, you will be exposed to the negative performance of the worst performing underlying index at maturity, even if the other underlying index has appreciated or has not declined as much, and you will lose a significant portion or all of your investment. Accordingly, your investment is subject to the price risk of both underlying indices.

￭Because the Trigger PLUS are linked to the performance of the worst performing underlying index, you are exposed to greater risk of sustaining a significant loss on your investment than if the Trigger PLUS were linked to just one underlying index. The risk that you will suffer a significant loss on your investment is greater if you invest in the Trigger PLUS as opposed to substantially similar securities that are linked to just the performance of one underlying index. With two underlying indices, it is more likely that either underlying index will decline to below its trigger level as of the valuation date, than if the Trigger PLUS were linked to only one underlying index. Therefore it is more likely that you will suffer a significant loss on your investment.

￭Higher future prices of the futures contract to which the SPXFP Index is linked relative to its current prices may adversely affect the value of the SPXFP Index and the value of the Trigger PLUS. The SPXFP Index is linked to the E-mini S&P 500 futures contract currently listed for trading on the CME. As the relevant futures contract approaches expiration, it is replaced by a contract that has a later expiration. Thus, for example, a contract purchased and held in September may specify a December expiration. As time passes, the contract expiring in December is replaced by a contract for delivery in March. This process is referred to as “rolling.” If the market for these contracts is (putting aside other considerations) in “backwardation,” where the prices are lower in the distant delivery months than in the nearer delivery months, the sale of the December contract would take place at a price that is higher than the price of the March contract, thereby creating a “roll yield.” While many futures contracts have historically exhibited consistent periods of backwardation, backwardation will most likely not exist at all times. It is also possible for the market for these contracts to be in “contango.” Contango markets are those in which the prices of contracts are higher in the distant delivery months than in the nearer delivery months. The presence of contango and absence of backwardation in the market

for these contracts could result in negative “roll yields,” which could adversely affect the value of the SPXFP Index, and, accordingly, the value of the Trigger PLUS.

￭Suspensions or disruptions of market trading in futures markets could adversely affect the price of the Trigger PLUS. Securities markets and futures markets are subject to temporary distortions or other disruptions due to various factors, including the lack of liquidity in the markets, the participation of speculators and government regulation and intervention. In addition, U.S. futures exchanges and some foreign exchanges have regulations that limit the amount of fluctuation in futures contract prices which may occur during a single business day. These limits are generally referred to as “daily price fluctuation limits” and the maximum or minimum price of a contract on any given day as a result of these limits is referred to as a “limit price.” Once the limit price has been reached in a particular contract, no trades may be made at a different price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices. These circumstances could adversely affect the value of the SPXFP Index, and, therefore, the value of the Trigger PLUS.

￭Legal and regulatory changes could adversely affect the return on and value of your Trigger PLUS. Futures contracts and options on futures contracts, including those related to the SPXFP Index, are subject to extensive statutes, regulations, and margin requirements. The Commodity Futures Trading Commission, commonly referred to as the “CFTC,” and the exchanges on which such futures contracts trade, are authorized to take extraordinary actions in the event of a market emergency, including, for example, the retroactive implementation of speculative position limits or higher margin requirements, the establishment of daily limits and the suspension of trading. Furthermore, certain exchanges have regulations that limit the amount of fluctuations in futures contract prices that may occur during a single five-minute trading period. These limits could adversely affect the market prices of relevant futures and options contracts and forward contracts.

￭Adjustments to the underlying indices could adversely affect the value of the Trigger PLUS. The publisher of either 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 either 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 Trigger PLUS

Annex A — S&P 500® Futures Excess Return Index

The S&P 500® Futures Excess Return Index (the “underlying index”) is an equity futures index calculated, maintained and published by S&P® Dow Jones Indices LLC (“S&P®”). S&P® is a joint venture between S&P® Global, Inc. (majority owner) and CME Group Inc. (minority owner), owner of CME Group Index Services LLC. The underlying index is reported by Bloomberg under the ticker symbol “SPXFP.” All information contained in this document regarding the underlying index has been derived from publicly available information, without independent verification.

The underlying index is the excess return version of the S&P 500 Futures Index, which measures the performance of the nearest maturing quarterly E-mini S&P 500 futures contract trading on the Chicago Mercantile Exchange (“CME”). The underlying index includes a provision for the replacement of the E-mini futures contract as the contract approaches maturity (also referred to as “rolling” or “the roll”). This replacement occurs over a one-day rolling period every March, June, September and December, effective after the close of trading five business days preceding the last trading date of the E-mini S&P futures contract.

E-Mini S&P 500 Futures Contract

The underlying index is constructed from the front-month E-mini S&P 500 futures contract (the “futures contract”). Futures contracts are contracts that legally obligate the holder to buy or sell an asset at a predetermined delivery price during a specified future time period. The futures contract is rolled forward once a quarter, with one-third of the contract being rolled forward on each of the fourth, third, and second day prior to expiration.

The E-mini S&P 500 futures (“ES”) contracts are U.S. dollar-denominated futures contracts, based on the S&P 500® Index (the “reference index”), traded on the CME, representing a contract unit of $50 multiplied by the reference index, measured in cents per index point. The ES contracts listed for the nearest nine quarters, for each March, June, September and December, and the nearest three Decembers are available for trading. Trading of the ES contracts terminates at 9:30 A.M. Eastern time on the third Friday of the contract month. The daily settlement prices of the ES contracts are based on trading activity in the relevant contract (and in the case of a lead month also being the expiry month, together with trading activity on lead month-second month spread contracts) on the CME during a specified settlement period. The final settlement price of ES contracts is based on the opening prices of the component stocks in the reference index, determined on the third Friday of the contract month. For more information about the reference index, see “S&P® U.S. Indices—S&P 500® Index” in the accompanying index supplement.

Underlying Index Calculation

The underlying index, calculated from the price change of the futures contract, reflects the excess return of the S&P 500 Futures Index. The level of the underlying index on a trading day is calculated as follows:

IndexERd = IndexERd-1 × (1 + CDRd)

where:

The underlying index is calculated on an excess return basis, meaning that the level of the underlying index is determined by its weighted return reduced by the return that could be earned on a notional cash deposit at the notional interest rate, which is a rate equal to the federal funds rate.

Overview of Futures Markets

Futures contracts are traded on regulated futures exchanges, in the over-the-counter market and on various types of electronic trading facilities and markets. As of the date of this pricing supplement, the futures contract is an exchange-traded futures contract. A futures contract provides for a specified settlement month in which the cash settlement is made by the seller (whose position is therefore described as “short”) and acquired by the purchaser (whose position is therefore described as “long”).

No purchase price is paid or received on the purchase or sale of a futures contract. Instead, an amount of cash or cash equivalents must be deposited with the broker as “initial margin.” This amount varies based on the requirements imposed by the exchange clearing houses, but it may be lower than 5% of the notional value of the contract. This margin deposit provides collateral for the obligations of the parties to the futures contract.

By depositing margin, which may vary in form depending on the exchange, with the clearing house or broker involved, a market participant may be able to earn interest on its margin funds, thereby increasing the total return that it may realize from an investment in futures contracts. However, the underlying index is not a total return index and does not reflect interest that could be earned on funds notionally committed to the trading of futures contracts.

At any time prior to the expiration of a futures contract, a trader may elect to close out its position by taking an opposite position on the exchange on which the trader obtained the position, subject to the availability of a liquid secondary market. This operates to terminate the position and fix the trader’s profit or loss. Futures contracts are cleared through the facilities of a centralized clearing house and a brokerage firm that is a member of the clearing house. Futures exchanges may adopt rules and take other actions that affect trading, including imposing speculative position limits, maximum price fluctuations and trading halts and suspensions and requiring liquidation of contracts in certain circumstances.
