Additional Provisions

LIBOR Reference Rate

“LIBOR” as defined in the accompanying prospectus in the section called “Description of Debt Securities – Floating Rate Debt Securities” and “– Base Rates” with an index maturity of 6 months and an index currency of US dollars and as displayed on Reuters Page LIBOR01; provided that for the determination of the LIBOR reference rate on any calendar day, the “interest determination date” shall be that calendar day unless that calendar day is not a London banking day, in which case the LIBOR reference rate shall be the LIBOR reference rate on the immediately preceding London banking day; provided further that the LIBOR reference rate for any day from and including the fifth New York banking day prior to the related interest payment date for any interest payment period shall be the LIBOR reference rate as in effect on the London banking day immediately preceding such fifth New York banking day prior to such interest payment date.

New York Banking Day

New York banking day means any day on which commercial banks are open for general business (including dealings in foreign exchange and foreign currency deposits) in New York, New York.

Index: The S&P 500® Index

The S&P 500® Index, which is calculated, maintained and published by Standard & Poor’s, a Division of The McGraw-Hill Companies, Inc., consists of 500 component stocks selected to provide a performance benchmark for the U.S. equity markets. The calculation of the S&P 500 Index is based on the relative value of the float adjusted aggregate market capitalization of the 500 component companies as of a particular time as compared to the aggregate average market capitalization of the 500 similar companies during the base period of the years 1941 through 1943. The S&P 500 Index is described under “Annex A—The S&P 500® Index” in these preliminary terms.

Index Closing Value

For any interest determination date, the index closing value for any calendar day will equal the closing value of the index as published on Bloomberg under ticker symbol “SPX,” or in the case of any successor index, the Bloomberg ticker symbol for any such successor index, at the regular weekday close of trading on that calendar day, as determined by the calculation agent; provided that if a market disruption event with respect to the index occurs on any interest determination date or if any such interest determination date is not an index business day, the closing value of the index for such interest determination date will be the closing value of the index on the immediately preceding index business day on which no market disruption event has occurred; provided further that the index closing value for any day from and including the fifth trading day prior to the related interest payment date for any interest payment period shall be the index closing value in effect on the index business day on which no market disruption event has occurred immediately preceding such fifth trading day prior to such interest payment date. In certain circumstances, the index closing value shall be based on the alternate calculation of the index described under “Discontinuance of the Underlying Index; Alteration of Method of Calculation.”

“Index business day” means a day, as determined by the calculation agent, on which trading is generally conducted on each of the relevant exchange(s) for the index, other than a day on which trading on such exchange(s) is scheduled to close prior to the time of the posting of its regular final weekday closing price.

“Trading day” means a day, as determined by the calculation agent, on which trading is generally conducted on the New York Stock Exchange, The NASDAQ Stock Market LLC, the Chicago Mercantile Exchange, the Chicago Board of Options Exchange and in the over-the-counter market for equity securities in the United States.

“Relevant exchange” means the primary exchange(s) or market(s) of trading for (i) any security then included in the index, or any successor index, and (ii) any futures or options contracts related to the index or to any security then included in the index.

Market Disruption Event

Market disruption event means, with respect to the index, the occurrence or existence of any of the following events, as determined by the calculation agent in its sole discretion: (i)(a) a suspension, absence or material limitation of trading of stocks then constituting 20 percent or more of the value of the index (or the successor index) on the relevant exchanges for such securities for more than two hours of trading or during the one-half hour period preceding the close of the principal trading session on such relevant exchange; or (b) a breakdown or failure in the price and trade reporting systems of any relevant exchange as a result of which the reported trading prices for stocks then constituting 20 percent or more of the value of the index (or the successor index) during the last one-half hour preceding the close of the principal trading session on such relevant exchange are materially inaccurate; or (c) the suspension, material limitation or absence of trading on any major U.S. securities market for trading in futures or options contracts or exchange traded funds related to the index (or the successor index) for more

6-Month USD LIBOR and S&P 500® Index Range Accrual Notes

than two hours of trading or during the one-half hour period preceding the close of the principal trading session on such market; and (ii) a determination by the calculation agent in its sole discretion that any event described in clause (i) above materially interfered with the ability of the issuer or any of its affiliates to unwind or adjust all or a material portion of the hedge position with respect to this issuance of the notes.

For the purpose of determining whether a market disruption event exists at any time, if trading in a security included in the index is materially suspended or materially limited at that time, then the relevant percentage contribution of that security to the value of the index shall be based on a comparison of (x) the portion of the value of the index attributable to that security relative to (y) the overall value of the index, in each case immediately before that suspension or limitation.

For the purpose of determining whether a market disruption event has occurred: (1) a limitation on the hours or number of days of trading shall not constitute a market disruption event if it results from an announced change in the regular business hours of the relevant exchange or market, (2) a decision to permanently discontinue trading in the relevant futures or options contract or exchange traded fund shall not constitute a market disruption event, (3) a suspension of trading in futures or options contracts or exchange traded funds on the index by the primary securities market trading in such contracts or funds by reason of (a) a price change exceeding limits set by such securities exchange or market, (b) an imbalance of orders relating to such contracts or funds, or (c) a disparity in bid and ask quotes relating to such contracts or funds shall constitute a suspension, absence or material limitation of trading in futures or options contracts or exchange traded funds related to the index and (4) a “suspension, absence or material limitation of trading” on any relevant exchange or on the primary market on which futures or options contracts or exchange traded funds related to the index are traded shall not include any time when such securities market is itself closed for trading under ordinary circumstances.

Discontinuance of the Underlying Index; Alteration of Method of Calculation

If S&P discontinues publication of the index and S&P or another entity (including the agent) publishes a successor or substitute index that the calculation agent determines, in its sole discretion, to be comparable to the discontinued index (such index being referred to herein as a “successor index”), then any subsequent index closing value shall be determined by reference to the published value of such successor index at the regular weekday close of trading on any index business day that the index closing value is to be determined.

If the publication of the index is discontinued and such discontinuance is continuing at any time when an index closing value is to be determined and the calculation agent determines, in its sole discretion, that no successor index is available at such time, then the calculation agent will determine the index closing value at such time in accordance with the formula for calculating the index last in effect prior to such discontinuance, without rebalancing or substitution, using the price at such time (or, if trading in the relevant securities has been materially suspended or materially limited, its good faith estimate of the price that would have prevailed but for such suspension or limitation) of each security most recently comprising the index on the relevant exchange.

Notwithstanding these alternative arrangements, discontinuance of the publication of the index may adversely affect the value of the notes.

Upon any selection by the calculation agent of a successor index, the calculation agent will cause written notice thereof to be furnished to the trustee, to the issuer and to The Depository Trust Company ("DTC"), as holder of the notes, within three trading days of such selection. We expect that such notice will be made available to you, as a beneficial owner of the notes, as applicable, in accordance with the standard rules and procedures of DTC and its direct and indirect participants.

If at any time the method of calculating the index or a successor index, or the value thereof, is changed in a material respect, or if the index or a successor index is in any other way modified so that such index does not, in the sole opinion of the calculation agent, fairly represent the value of the index or such successor index had such changes or modifications not been made, then, from and after such time, the calculation agent will, at any time at which the index closing value is to be determined, make such calculations and adjustments as, in the good faith judgment of the calculation agent, may be necessary in order to arrive at a value of an index comparable to the index or a successor index, as the case may be, as if such changes or modifications had not been made, and the calculation agent will determine the index closing value, as adjusted. Accordingly, if the method of calculating the index or a successor index is modified so that the value of such index is a fraction of what it would have been if it had not been modified (e.g., due to a split in the index), then the calculation agent will adjust such index in order to arrive at a value of the index or such successor index as if it had not been modified (i.e., as if such split had not occurred).

Hypothetical Examples

The table below presents examples of the hypothetical quarterly interest rate that would accrue on the notes during the floating interest rate period based on the total number of calendar days in an interest payment period on which the LIBOR reference rate is within the LIBOR reference rate range and the index closing value is greater than or equal to the index reference level. The table assumes that the interest payment period contains 90 calendar days and an interest rate of 10.00% per annum.

The example below is for purposes of illustration only and would provide different results if different assumptions were made. The actual quarterly interest rate and payments will depend on the actual number of calendar days in each interest payment period and the actual index closing value and LIBOR reference rate level on each day. The applicable interest rate for each quarterly interest payment period will be determined on a per-annum basis but will apply only to that interest payment period.

N		Hypothetical Interest Rate
0		0.000%
25		2.778%
50		5.556%
75		8.333%
90		10.000%

Historical Information

LIBOR Reference Rate

The following graph sets forth the LIBOR reference rate for the period from January 1, 1994 to November 30, 2009. The historical performance of the LIBOR reference rate should not be taken as an indication of its future performance. We cannot give you any assurance that the LIBOR reference rate will be within the LIBOR reference rate range on any day of any interest payment period during the floating interest rate period. We obtained the information in the graph below from Bloomberg Financial Markets, without independent verification.

The following table sets forth the published high and low index closing values, as well as end-of-quarter index closing values, for each quarter in the period from January 1, 2004 through November 30, 2009. The graph following the table sets forth the daily closing values of the index for the period from January 1, 1994 through November 30, 2009. The closing value of the index on November 30, 2009 was 1,095.63. We obtained the information in the table below from Bloomberg Financial Markets, without independent verification. The historical values of the S&P 500® index should not be taken as an indication of future performance, and no assurance can be given as to the level of the index on any calendar day during the term of the notes. The graph below does not reflect the return the notes would have had during the periods presented because it does not take into account the LIBOR reference rate or our redemption right.

Risk Factors

The notes involve risks not associated with an investment in ordinary floating rate notes. An investment in the notes entails significant risks not associated with similar investments in a conventional debt security, including, but not limited to, fluctuations in the LIBOR reference rate and the index, and other events that are difficult to predict and beyond the issuer’s control. This section describes the most significant risks relating to the notes. For a complete list of risk factors, please see the accompanying prospectus supplement and the accompanying prospectus. You should carefully consider whether the notes are suited to your particular circumstances before you decide to purchase them. Accordingly, prospective investors should consult their financial and legal advisers as to the risks entailed by an investment in the notes and the suitability of the notes in light of their particular circumstances.

If there are no accrual days in any interest payment period during the floating interest rate period, we will not pay any interest on the notes for that interest payment period and the market value of the notes may decrease. It is also possible that the LIBOR reference rate will not be within the LIBOR reference rate range or that the index closing value will be less than the index reference level for so many days during any quarterly interest payment period during the floating interest rate period, that the interest payment for that quarterly interest payment period will be less than the amount that would be paid on an ordinary debt security and may be zero. To the extent that the LIBOR reference rate is not within the LIBOR reference rate range or that the index closing value is less than the index reference level, during the floating interest rate period, the market value of the notes may decrease and you may receive substantially less than 100% of the issue price if you wish to sell your notes at such time.

The LIBOR reference rate for any day from and including the fifth New York banking day prior to the interest payment date of an interest payment period during the floating interest rate period will be the LIBOR reference rate on the London banking day immediately prior to such fifth day. Because the LIBOR reference rate for any day from and including the fifth New York banking day prior to the interest payment date of an interest payment period during the floating interest rate period will be the LIBOR reference rate on the London banking day immediately prior to such fifth day, if the LIBOR reference rate on that London banking day is not within the LIBOR reference rate range, you will not receive any interest in respect of those three days even if the LIBOR reference rate as actually calculated on any of those days were to be within the LIBOR reference rate range.

Investors are subject to our credit risk, and our credit ratings and credit spreads may adversely affect the market value of the notes. Investors are dependent on our ability to pay all amounts due on the notes on interest payment dates, redemption dates and at maturity and therefore investors are subject to our credit risk and to changes in the market’s view of our creditworthiness. Any 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 notes.

The index closing value for any day from and including the fifth trading day prior to the interest payment date of an interest payment period during the floating interest rate period will be the index closing value on the index business day immediately prior to such fifth day. Because the index closing value for any day from and including the fifth trading day prior to the interest payment date of an interest payment period during the floating interest rate period will be the index closing value on the index business day immediately prior to such fifth day, if the index closing value on that index business day is less than the index reference level, you will not receive any interest in respect of those three days even if the index closing value as actually calculated on any of those days were to be greater than or equal to the index reference level.

Early redemption risk. The issuer retains the option to redeem the notes after the stated period of time, with the stated frequency and prior to the defined notice date(s). It is more likely that the issuer will redeem the notes prior to their stated maturity date to the extent that the LIBOR reference rate and the index closing value during the during the floating interest rate period results in an amount of interest payable that is greater than instruments of a comparable maturity and credit rating trading in the market. If the notes are redeemed prior to their stated maturity date, investors may have to re-invest proceeds in a lower rate environment.

The historical performance of the LIBOR reference rate and the index are not an indication of future performance. Historical performance of the LIBOR reference rate and the index should not be taken as an indications of their future performance during the term of the notes. Changes in the levels of the LIBOR reference rate and the index will affect the trading price of the notes, but it is impossible to predict whether such levels will rise or fall.

December 2009

Senior Floating Rate Notes due 2024

6-Month USD LIBOR and S&P 500® Index Range Accrual Notes

The price at which the notes may be sold prior to maturity will depend on a number of factors and may be substantially less than the amount for which they were originally purchased. Some of these factors include, but are not limited to: (i) changes in the level of the LIBOR reference rate, (ii) changes in the level of the index closing value, (iii) volatility of the LIBOR reference rate, (iv) volatility of the index, (v) changes in interest and yield rates, (vi) geopolitical conditions and economic, financial, political and regulatory or judicial events that affect the securities underlying the index, or equity markets generally, and that may affect the index, (vii) any actual or anticipated changes in our credit ratings or credit spreads, and (viii) time remaining to maturity. Primarily, to the extent that the LIBOR reference rate level remains outside the LIBOR reference rate range or the index closing value is less than the index reference level, during the floating interest rate period, the market value of the notes may decrease and you may receive substantially less than 100% of the issue price if you wish to sell your notes at such time.

The inclusion of commissions and projected profit from hedging in the original issue price is likely to adversely affect secondary market prices. Assuming no change in market conditions or any other relevant factors, the price, if any, at which Morgan Stanley & Co. Incorporated (“MS & Co.”) is willing to purchase notes in secondary market transactions will likely be lower than the original issue price, since the original issue price will include, and secondary market prices are likely to exclude, commissions paid with respect to the notes, as well as the cost of hedging our obligations under the notes. The cost of hedging includes the projected profit that our subsidiaries may realize in consideration for assuming the risks inherent in managing the hedging transactions. In addition, any secondary market prices may differ from values determined by pricing models used by MS & Co., as a result of dealer discounts, mark-ups or other transaction costs.

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

Issuer or its affiliates are market participants. The issuer or one or more of their respective affiliates may, at present or in the future, publish research reports with respect to movements in interests rates generally or the LIBOR reference rate specifically, or with respect to the index. This research is modified from time to time without notice and may express opinions or provide recommendations that are inconsistent with purchasing or holding the notes. Any of these activities may affect the market value of the notes.

Economic interests of the calculation agent may be potentially adverse to the investors. The calculation agent is an affiliate of the issuer. Any determinations made by the calculation agent may adversely affect the payout to investors. Determinations made by the calculation agent, including with respect to the LIBOR reference rate, the index closing value, 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 discontinuance of the index, may adversely affect the payout to you on the notes. See “Additional Provisions—Market Disruption Event” and “—Discontinuance of the Index; Alteration of Method of Calculation.”

S&P 500® Index Specific Risk Factors

Adjustments to the index could adversely affect the value of the notes. The publisher of the index can add, delete or substitute the stocks underlying the index, and can make other methodological changes required by certain events relating to the underlying stocks, such as stock dividends, stock splits, spin-offs, rights offerings and extraordinary dividends, that could change the value of the index. Any of these actions could adversely affect the value of the notes. The publisher of the index may discontinue or suspend calculation or publication of the 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 index. The calculation agent could have an economic interest that is different than that of investors in the notes insofar as, for example, the calculation agent is not precluded from considering indices that are calculated and published by the calculation agent or any of its affiliates. If the calculation agent determines that there is no appropriate successor index, on any day on which the index closing value is to be determined, the index closing value for such day will be based on the stocks underlying the discontinued index at the time of such discontinuance, without rebalancing or substitution, computed by the calculation agent, in accordance with the formula for calculating the index closing value last in effect prior to discontinuance of the index.

§	You have no shareholder rights. As an investor in the notes, you will not have voting rights, rights to receive dividends or other distributions or any other rights with respect to the stocks that underlie the index.

§	Investing in the notes is not equivalent to investing in the index or the stocks underlying the index. Investing in the notes is not equivalent to investing in the index or its component stocks.

Hedging and trading activity by the calculation agent and its affiliates could potentially adversely affect the value of the index. The calculation agent and other of its affiliates will carry out hedging activities related to the notes (and possibly to other instruments linked to the index or its component stocks), including trading in the stocks underlying the index as well as in other instruments related to the index. The calculation agent and some of its other subsidiaries also trade in the stocks underlying the index and other financial instruments related to the index 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 day the notes are priced for initial sale to the public could potentially decrease the index closing value, thus increasing the risk that the index closing value will be less than the index reference level during the term of the notes.

Supplemental Information Concerning Plan of Distribution; Conflicts of Interest

We expect to deliver the notes against payment therefor in New York, New York on December 18, 2009, which will be the scheduled business day following the date of the pricing of the notes. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of pricing or on or prior to the third business day prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The agent may distribute the notes through Morgan Stanley Smith Barney LLC (“MSSB”), as selected dealer, or other dealers, which may include Morgan Stanley & Co. International plc ("MSIP") and Bank Morgan Stanley AG. MSSB, MSIP and Bank Morgan Stanley AG are affiliates of Morgan Stanley.

MS & Co. is our wholly-owned subsidiary. MS & Co. will conduct this offering in compliance with the requirements of NASD Rule 2720 of the Financial Industry Regulatory Authority, Inc., which is commonly referred to as FINRA, regarding a FINRA member firm’s distribution of the securities of an affiliate and related conflicts of interest. In accordance with NASD Rule 2720, MS & Co. or any of our other affiliates may not make sales in this offering to any discretionary account without the prior written approval of the customer.

Tax Considerations

The notes should be treated as “variable rate debt instruments” for U.S. federal income tax purposes, as described in the section of the accompanying prospectus supplement called “United States Federal Taxation ― Tax Consequences to U.S. Holders ― Notes ― Floating Rate Notes.” Both U.S. and non-U.S. holders should read the section of the accompanying prospectus supplement entitled “United States Federal Taxation.”

You should consult your tax advisers regarding all aspects of the U.S. federal tax consequences of an investment in the notes, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

6-Month USD LIBOR and S&P 500® Index Range Accrual Notes

Annex A—The S&P 500® Index

The S&P 500® Index was developed by Standard & Poor’s, a Division of The McGraw-Hill Companies, Inc., which we refer to as S&P, and is calculated, maintained and published by S&P.

The S&P 500® Index is intended to provide a performance benchmark for the U.S. equity markets. The calculation of the value of the S&P 500® Index (discussed below in further detail) is based on the relative value of the aggregate Market Value (as defined below) of the common stocks of 500 companies (the “S&P 500 Component Stocks”) as of a particular time as compared to the aggregate average Market Value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943. The “Market Value” of any S&P 500 Component Stock is the product of the market price per share and the number of the then outstanding shares of such S&P 500 Component Stock. The 500 companies are not the 500 largest companies listed on the New York Stock Exchange and not all 500 companies are listed on such exchange. S&P chooses companies for inclusion in the S&P 500® Index with an aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the U.S. equity market. S&P may from time to time, in its sole discretion, add companies to, or delete companies from, the S&P 500® Index to achieve the objectives stated above. Relevant criteria employed by S&P include the viability of the particular company, the extent to which that company represents the industry group to which it is assigned, the extent to which the company’s common stock is widely-held and the Market Value and trading activity of the common stock of that company.

The S&P 500® Index and S&P’s other U.S. indices moved to a float adjustment methodology in 2005 so that the indices reflect only those shares that are generally available to investors in the market rather than all of a company’s outstanding shares. Float adjustment excludes shares that are closely held by other publicly traded companies, venture capital firms, private equity firms, strategic partners or leveraged buyout groups; government entities; or other control groups, such as a company’s own current or former officers, board members, founders, employee stock ownership plans or other investment vehicles controlled by the company or such other persons.

The S&P 500® Index is calculated using a base-weighted aggregate methodology: the level of the S&P 500® Index reflects the total Market Value of all 500 S&P 500 Component Stocks relative to the S&P 500® Index’s base period of 1941-43 (the “Base Period”). An indexed number is used to represent the results of this calculation in order to make the value easier to work with and track over time. The actual total Market Value of the S&P 500 Component Stocks during the Base Period has been set equal to an indexed value of 10. This is often indicated by the notation 1941-43=10. In practice, the daily calculation of the S&P 500® Index is computed by dividing the total Market Value of the S&P 500 Component Stocks by a number called the “S&P 500 Index Divisor.” By itself, the S&P 500 Index Divisor is an arbitrary number. However, in the context of the calculation of the S&P 500® Index, it is the only link to the original base period value of the S&P 500® Index. The S&P 500 Index Divisor keeps the S&P 500® Index comparable over time and is the manipulation point for all adjustments to the S&P 500® Index (“S&P 500 Index Maintenance”).

S&P 500 Index Maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to company restructurings or spinoffs.

To prevent the value of the S&P 500® Index from changing due to corporate actions, all corporate actions which affect the total Market Value of the S&P 500® Index require a S&P 500 Index Divisor adjustment. By adjusting the S&P 500 Index Divisor for the change in total Market Value, the value of the S&P 500® Index remains constant. This helps maintain the value of the S&P 500® Index as an accurate barometer of stock market performance and ensures that the movement of the S&P 500® Index does not reflect the corporate actions of individual companies in the S&P 500® Index. All S&P 500 Index Divisor adjustments are made after the close of trading and after the calculation of the closing value of the S&P 500® Index. Some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the companies in the S&P 500® Index and do not require S&P 500 Index Divisor adjustments.

The table below summarizes the types of S&P 500 Index maintenance adjustments and indicates whether or not a S&P 500 Index Divisor adjustment is required:

Senior Floating Rate Notes due 2024

6-Month USD LIBOR and S&P 500® Index Range Accrual Notes

Type of Corporate Action	Adjustment Factor	Divisor Adjustment Required
Stock split (e.g., 2-for-1)	Shares Outstanding multiplied by 2; Stock Price divided by 2	No
Share issuance (i.e., change ≥ 5%)	Shares Outstanding plus newly issued Shares	Yes
Share repurchase (i.e., change ≥ 5%)	Shares Outstanding minus Repurchased Shares	Yes
Special cash dividends	Share Price minus Special Dividend	Yes
Company Change	Add new company Market Value minus old company Market Value	Yes
Rights Offering	Price of parent company minus	Yes
	Price of Rights Right Ratio
Spin-Off	Price of parent company minus	Yes
	Price of Spinoff Co. Share Exchange Ratio

Stock splits and stock dividends do not affect the S&P 500 Index Divisor of the S&P 500® Index, because following a split or dividend both the stock price and number of shares outstanding are adjusted by S&P so that there is no change in the Market Value of the S&P 500 Component Stock. All stock split and dividend adjustments are made after the close of trading on the day before the ex-date.

Each of the corporate events exemplified in the table requiring an adjustment to the S&P 500 Index Divisor has the effect of altering the Market Value of the S&P 500 Component Stock and consequently of altering the aggregate Market Value of the S&P 500 Component Stocks (the “Post-Event Aggregate Market Value”). In order that the level of the S&P 500® Index (the “Pre-Event Index Value”) not be affected by the altered Market Value (whether increase or decrease) of the affected S&P 500 Component Stock, a new S&P 500 Index Divisor (“New S&P 500 Divisor”) is derived as follows:

Post-Event Aggregate Market Value

New S&P 500 Divisor

Pre-Event Index Value

New S&P 500 Divisor

Post-Event Aggregate Market Value

Pre-Event Index Value

A large part of the S&P 500 Index maintenance process involves tracking the changes in the number of shares outstanding of each of the S&P 500® Index companies. Four times a year, on a Friday close to the end of each calendar quarter, the share totals of companies in the S&P 500® Index are updated as required by any changes in the number of shares outstanding. After the totals are updated, the S&P 500 Index Divisor is adjusted to compensate for the net change in the total Market Value of the S&P 500® Index. In addition, any changes over 5% in the current common shares outstanding for the S&P 500® Index companies are carefully reviewed on a weekly basis, and when appropriate, an immediate adjustment is made to the S&P 500 Index Divisor.
