U.S. Indices
Dow Jones Industrial Average^® Index

The Dow Jones Industrial Average (the “DJIA Index”) is a benchmark of performance for leading companies in the U.S. stock market. The DJIA Index consists of 30 “blue-chip” U.S. stocks, although this has not always been the case. The number of stocks in the DJIA Index was 12 in 1896, rose to 20 in 1916, then to 30 in 1928, and has been at that level ever since.

The DJIA Index is calculated by adding up the prices of the 30 constituent stocks and dividing the total by a divisor. The divisor is now a number that reflects adjustments over time resulting from spin-offs, stock splits, stock dividends and other corporate actions, as well as additions and deletions to the DJIA Index. The adjustments to the divisor also allow the DJIA Index calculation to remain comparable over time.

According to Dow Jones, the DJIA Index is maintained and reviewed by the editors of The Wall Street Journal. While there are no rules for component selection, a stock typically is added only if it has an excellent reputation, demonstrates sustained growth, is of interest to a large number of investors and accurately represents the sector(s) covered by the average. The DJIA Index is not limited to traditionally defined industrial stocks. Instead, the DJIA Index serves as a measure of the entire US market, covering such diverse industries as financial services, technology, retail, entertainment and consumer goods.

For the sake of continuity, changes to the composition of the DJIA Index are rare, and generally occur only after corporate acquisitions or other dramatic shifts in a component’s core business. When such an event necessitates that one component be replaced, the entire DJIA Index is reviewed by the editors of The Wall Street Journal. As a result, multiple component changes are often implemented simultaneously.

We have derived all information regarding the DJIA Index contained in this index supplement from publicly available information. Such information reflects the policies of, and is subject to change by, Dow Jones & Company, Inc. (“Dow Jones”). Dow Jones owns the copyright and all other rights to the DJIA Index. Dow Jones has no obligation to continue to publish, and may discontinue publication of, the DJIA Index. We do not assume any responsibility for the accuracy or completeness of such information. Historical performance of the DJIA Index is not an indication of future performance. Future performance of the DJIA Index may differ significantly from historical performance, either positively or negatively.

NASDAQ-100^® Index

The Nasdaq-100^® (the “Nasdaq Index”) Index includes 100 of the largest domestic and international non-financial securities listed on the Nasdaq Stock Market^® based on market capitalization. The Nasdaq Index reflects companies across major industry groups including computer hardware and software, telecommunications, retail and wholesale trade, and biotechnology. It does not contain securities of financial companies, including investment companies. The Nasdaq Index was first published in January 1985. Current information regarding the market level of the Nasdaq Index is available from The Nasdaq OMX Group, Inc. and its affiliates (collectively referred to herein as the “Corporations”) and from numerous market information services. The level of the Nasdaq Index is determined, comprised and calculated by the Corporations without regard to any Securities linked to the Nasdaq Index.

The Nasdaq Index is calculated under a modified capitalization-weighted methodology. The methodology is expected to retain in general the economic attributes of capitalization-weighting while providing enhanced diversification. To accomplish this, the Corporations will review the composition of the Nasdaq Index on a quarterly basis and adjust the weightings of Index components using a proprietary algorithm, if certain pre-established weight distribution requirements are not met.

To be eligible for initial inclusion in the Nasdaq Index, a security must be listed on the Nasdaq Stock Market^® and meet the following criteria:

(a) the security’s U.S. listing must be exclusively on the Nasdaq National Market^® (unless the security was dually listed on another U.S. market prior to January 1, 2004 and has continuously maintained such listing);

(b) the security must be of a non-financial company;

(c) the security may not be issued by an issuer currently in bankruptcy proceedings;

(d) the security must have average daily trading volume of at least 200,000 shares;

(e) if the issuer of the security is organized under the laws of a jurisdiction outside the U.S., then such security must have listed options on a recognized options market in the U.S. or be eligible for listed-options trading on a recognized options market in the U.S.;

(f) only one class of security per issuer is allowed;

(g) the issuer of the security may not have entered into a definitive agreement or other arrangement which would likely result in the security no longer being Nasdaq Index eligible;

(h) the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn;

(i) the issuer of the security must have “seasoned” on Nasdaq National Market^® or another recognized market (generally, a company is considered to be seasoned if it has been listed on a market for at least two years); and

(j) if the security would otherwise qualify to be in the top 25% of the securities included in the Nasdaq Index by market capitalization for the six prior consecutive month-ends, then a one-year “seasoning” criterion would apply.

To be eligible for continued inclusion in the Nasdaq Index, besides meeting the criteria (a), (b), (c), (d), (e), (h) above, the security must have an adjusted market capitalization equal to or exceeding 0.10% of the aggregate adjusted market capitalization of the Nasdaq Index at each month-end. In the event a company does not meet this criterion for two consecutive month-ends, it will be removed from the Nasdaq Index effective after the close of trading on the third Friday of the following month.

IS-4

NASDAQ-100^® Index

Except under extraordinary circumstances that may result in an interim evaluation, Nasdaq Index composition is reviewed on an annual basis (“Ranking Review”). Securities listed on The Nasdaq Stock Market^® which meet the applicable eligibility criteria are ranked by market value. Index-eligible securities which are already in the Nasdaq Index and which are ranked in the top 100 eligible securities (based on market value) are retained in the Nasdaq Index. A security that is ranked 101 to 125 is also retained, provided that such security was ranked in the top 100 eligible securities as of the previous Ranking Review. Securities not meeting such criteria are replaced. The replacement securities chosen are those Nasdaq Index-eligible securities not currently in the Nasdaq Index that have the largest market capitalization. Generally, the list of annual additions and deletions is publicly announced via a press release in the early part of December. Replacements are made effective after the close of trading on the third Friday in December.

In addition to the Ranking Review, the securities in the Nasdaq Index are monitored every day by the Corporations with respect to changes in total shares outstanding arising from secondary offerings, stock repurchases, conversions, or other corporate actions. The Corporations have adopted the following weight adjustment procedures with respect to such changes. Changes in total shares outstanding arising from stock splits, stock dividends or spin-offs are generally made to the Nasdaq Index on the evening prior to the effective date of such corporate action. If the change in total shares outstanding arising from other corporate actions is greater than or equal to 5.0%, the change will be made as soon as practicable, normally within 10 days of such action. Otherwise, if the change in total shares outstanding is less than 5%, then all such changes are accumulated and made effective at one time on a quarterly basis after the close of trading on the third Friday in each of March, June, September, and December. In either case, the Nasdaq Index share weights for such securities are adjusted by the same percentage amount by which the total shares outstanding have changed in such securities.

Such information reflects the policies of, and is subject to change by the Corporations. The Corporations own the copyright and all other rights to the Nasdaq Index.

Russell 2000^® Index

The Russell 2000^® Index (the “Russell Index”) is an index calculated, published, and disseminated real-time by the Frank Russell Company (the “Russell Index Sponsor”), and measures the composite price performance of stocks of approximately 2,000 companies, each of which is (1) either (i) incorporated in the United States or one of its territories or (ii) incorporated in Anguilla, Antigua, Bahamas, Barbados, Belize, Bermuda, British Virgin Islands, Cayman Islands, Channel Islands, Cook Islands, Faroe Islands, Gibraltar, Isle of Man, Liberia, Marshall Islands, Netherlands Antilles, Panama and Turks and Caicos Islands (each, a “benefit-driven incorporation country” or “BDI Country”), and (2) either (i) its primary headquarters is in the United States or (ii) its primary headquarters is in a BDI Country and the exchange with the most trading volume of local shares is in the United States (the companies meeting the requirements of (1) and (2), “U.S.-Based Companies”). All 2,000 stocks form a part of the Russell 3000^® Index and represent approximately 8% of its total market capitalization. The Russell 3000^® Index is composed of the 3,000 largest U.S.-Based Companies as determined by market capitalization and represents approximately 98.00% of the U.S. equity market. The Russell Index consists of the smallest 2,000 companies included in the Russell 3000^® Index. The Russell Index is designed to track the performance of the small capitalization segment of the U.S. equity market. Both the Russell Index and the Russell 3000^® Index are subsets of the Russell 3000E^® Index, which is composed of the 4,000 largest U.S. Based Companies as determined by market capitalization and represents approximately 99.00% of the U.S. equity market.

Stocks Included in the Russell 2000^® Index

Only common stocks of U.S.-Based Companies are eligible for inclusion in the Russell 3000^® Index and the Russell Index. Preferred and convertible preferred stock, redeemable shares, participating preferred stock, warrants and rights, and trust receipts also are excluded from the Russell Index. In addition, companies structured as royalty trusts, limited liability companies, closed-end investment companies, blank check companies, special purpose acquisition vehicles (SPACs), and limited partnerships also are ineligible for inclusion in the Russell Index. Business development companies, however, are eligible for inclusion. As a special exception, Berkshire Hathaway is also excluded from the companies eligible for inclusion in the Russell Index, due to its similarity to a mutual fund and its lack of liquidity.

In general, only one class of securities of a company is allowed in the Russell Index, although exceptions to this general rule have been made where the Russell Index Sponsor has determined that each class of securities acts independently of the other. American Depository Receipts are excluded from the Russell Index. Eligible stocks must trade on a major U.S. exchange. Bulletin board, pink sheets and over-the-counter (OTC) traded stocks are excluded from the Russell Index. Stocks must trade at or above $1.00 on their primary exchange on May 31 of each year to be eligible for inclusion in the Russell Index. However, if the price of a stock falls below $1.00 intra-year, it will not be removed until the next reconstitution if it is still trading below $1.00. In addition, companies with only a small portion of their shares available in the market place (5% or less float for small capitalization companies) are ineligible for inclusion in the Russell Index.

From the cost of eligible securities, the primary criterion used to select securities for inclusion in the Russell 3000^® Index is total market capitalization, which is defined as the price of a company's shares times the total number of available shares, as described below. Based on closing values on May 31 of each year, the Russell Index Sponsor reconstitutes the composition of the Russell 3000^® Index using the then existing market capitalizations of eligible companies. As of the last Friday in June of each year (except when the last Friday in June is the 28th, 29th or 30th, in which case reconstitution will occur on the second to last Friday in June), the Russell Index is adjusted to reflect the reconstitution of the Russell 3000^® Index for that year.

IS-7

Russell 2000^® Index

Computation of the Russell 2000^® Index

As a capitalization-weighted index, the Russell Index reflects changes in the capitalization, or market value, of the component stocks relative to the capitalization on a base date. The current Russell Index value is calculated by adding the market values of the Russell Index's component stocks, which are derived by multiplying the price of each stock by the number of available shares, to arrive at the total market capitalization of the 2,000 stocks. The total market capitalization is then divided by a divisor, which represents the “adjusted” capitalization of the Russell Index on the base date of December 31, 1986. To calculate the Russell Index, last sale prices will be used for stocks. If a component stock is not open for trading, the most recently traded price for that stock will be used in calculating the Russell Index. In order to provide continuity for the Russell Index’s value, the divisor is adjusted periodically to reflect certain events, including changes in the number of common shares outstanding for component stocks, company additions or deletions, corporate restructurings, and other capitalization changes.

Available shares are assumed to be shares available for trading. Adjustments to a company’s total outstanding shares to determine available shares or “free float” are made based on information recorded in SEC filings. Other sources are used in cases of missing or questionable data.

The following types of shares are considered unavailable for the purposes of capitalization determinations:

Ø ESOP or LESOP shares — shares of Employee Stock Ownership Plans that comprise 10.00% or more of the shares outstanding are adjusted;

Ø Corporate cross-owned shares — when shares of a company in the index are held by another company also in the index, this is considered corporate cross-ownership, and such shares will be adjusted regardless of the percentage held;

Ø Large private and corporate shares — when an individual, a group of individuals acting together, or a corporation not in the index owns shares representing 10.00% or more of the shares outstanding such shares will be adjusted, although institutional holdings (i.e., holdings of investment companies, partnerships, insurance companies, mutual funds, banks, or venture capital companies) are not included in this adjustment;

Ø Unlisted share classes — classes of common stock that are not traded on a U.S. exchange;

Ø IPO lock ups — shares locked up during an initial public offering (IPO) are not available to the public and will be excluded from the market value at the time the company enters the Russell Index; and

Ø Government holdings — holdings held directly by government (listed as “government of”) are considered unavailable and will be removed entirely form available shares, and shares held indirectly by government investment boards and/or investment arms will be treated similar to large private holdings and removed if the holding is greater than 10.00%, although any holding by a government pension plan is considered an institutional holding and will not be removed from available shares.

The following summarizes the types of Russell Index maintenance adjustments and indicates whether or not an index adjustment is required.

Ø General rule for corporate action-driven changes — In general, adjustments for corporate action-driven changes are made by the Russell Index Sponsor when an action is final (determined by the Russell Index Sponsor with reference to a variety of public sources) and, depending on the time an action is determined to be final, the Russell Index Sponsor will either apply the action after the

IS-8

Russell 2000^® Index

close of the current market day (t) or after the close of the following market day (t+1). Stocks removed after the close of the current market day are typically removed at the last traded price.

Ø “No replacement” rule — Securities that leave the Russell Index, between reconstitution dates, for any reason (e.g., mergers, acquisitions, or other similar corporate activity) are not replaced. Thus, the number of securities in the Russell Index over a year will fluctuate according to corporate activity.

Ø Mergers and acquisitions — When mergers or acquisitions take place between members of the Russell Index, the acquired company is deleted and its market capitalization moves to the acquiring company’s stock; as a result, mergers between members have no effect on the total capitalization of the Russell Index. Special procedures apply to acquisitions or mergers between a member of the Russell Index and a non-member, and adjustments are made based on a variety of factors, including whether the member is the acquiring or acquired company and, if the acquired company, on whether the transaction results in a publicly traded company that meets all requirements for inclusion in the Russell Index.

Ø Reincorporations — Members of the Russell Index that are reincorporated in a country other than the United States and its territories or a BDI Country are deleted from the Russell Index. Members of the Russell Global Index reincorporating in the United States or its territories or a BDI country will be added to the Russell 3000E^® Index and may be included in the Russell Index if its market capitalization warrants such inclusion.

Ø Reclassifications of share classes — The class of securities of a company included in the Russell Index is typically re-examined by the Russell Index Sponsor at reconstitution, at the time of a major corporate action event, or with the issuance of a new share class. In general, adjustments are made at such times based on an equal weighted matrix of relative trading volume, price and float-adjusted shares. For changes outside of reconstitution, a determination is made one day prior to implementation of the change.

Ø Rights offerings — Rights offered to shareholders are reflected in the Russell Index on the date the offer expires for non-transferable rights and on the ex-date for transferable rights. In both cases, the price is adjusted to account for the value of the right, and shares are increased according to the terms of the offering on that day. Rights issued in anticipation of a takeover event or “poison pill” rights are excluded from this treatment and no price adjustment is made for their issuance or redemption.

Ø Changes to shares outstanding — Changes to shares outstanding due to buybacks (including Dutch auctions), secondary offerings, merger activity with a non-Russell Index member and other potential changes are updated at the end of the month in which the change is reflected in vendor-supplied updates and are verified by Russell Index Sponsor via SEC filings. For a change in shares to occur, the cumulative change available to the shares must be greater than 5.00%.

Ø Spin-offs — Spin-off companies are added to the parent company’s index and capitalization tier of membership, if the spin off is large enough. To be eligible, the spun-off company's total market capitalization must be greater than the market-adjusted total market capitalization of the smallest security in the Russell 3000E^® Index at the latest reconstitution. If the spun-off company is not large enough to be added to the Russell Index and is not trading on a “when-issued” basis, the Russell Index will recognize the performance of the spin-off during its first day of trading through a synthetic price/performance of the parent company.

Ø Tender offers — A company acquired as the result of a tender offer is removed only when the offer has fully expired and when it is determined by the Russell Index Sponsor that the company will finalize the process with a short-form merger. Because this information is typically not available until

IS-9

Russell 2000^® Index

after the close, the company will be removed at t+1 at the last traded market price, and shares of the acquiring company, if a Russell Index member, will be increased simultaneously at t+1, if applicable.

Ø Delisting — Only companies listed on U.S. exchanges are included in the Russell Index. Therefore, when a company is delisted from a U.S. exchange, the company is removed from the Russell Index.

Ø Bankruptcy and voluntary liquidations — Companies filing for Chapter 7 liquidation bankruptcy or that file any other liquidation plan will be removed from the Russell Index at the time of filing. Companies filing for Chapter 11 reorganization bankruptcy will remain members of the Russell Index, unless the companies are delisted from their primary exchange, in which case normal delisting rules as described above will apply.

Ø Stock distributions — Stock distributions can take two forms: (1) a stated amount of stock on the ex-date, or (2) an undetermined amount of stock based on earning and profits to be distributed at a future date. In both cases, a price adjustment is done on the ex-date of the distribution. Shares are increased on the ex-date for category (1) and on the pay-date for category (2).

Ø Dividends — Gross dividends are included in the daily total return calculation of the Russell Index based on their ex-dates. The ex-date is used rather than the pay-date, because the marketplace price adjustment for the dividend occurs on the ex-date. Monthly, quarterly and annual total returns are calculated by compounding the reinvestment of dividends daily. The reinvestment and compounding is at the total index level, not at the security level. Special cash dividends are treated the same as regular cash dividends unless the special cash dividend exceeds 10.00% of the share price of the underlying security. In that case, the price of the stock is adjusted to deduct the dividend amount on the ex-date.

Ø Halted securities — Securities that are not presently trading on their primary exchange are not removed from the Russell Index until the time they are actually delisted from the primary exchange. If a security is halted, it remains in the Russell Index at the last trade price from the primary exchange until the time the security resumes trading or is officially delisted. Special rules apply to securities on the New York Stock Exchange halted due to their being priced at less than $1.05.

Ø Quarterly IPO Additions — Eligible companies that have recently completed an initial public offering are added to the Russell Index at the end of each calendar quarter based on total market capitalization ranking within the market-adjusted capitalization breaks established during the most recent reconstitution. Market adjustments will be made using the returns of the Russell 3000E^® Index. In order to be added in a quarter outside of reconstitution, the IPO company must meet all Russell U.S. Index eligibility requirements. Additionally, the IPO company must meet the following criteria on the final trading day of the month prior to quarter-end: (1) price/trade; (2) rank larger in total market capitalization than the market-adjusted smallest company in the Russell 3000E^® Index as of the latest reconstitution; and (3) meet criteria (1) and (2) during an initial offering period.

S&P 500^® Index

The S&P 500^® Index (the “S&P Index”) is maintained by the S&P Index Committee (the “S&P Index Committee”), a team of S&P’s economists and index analysts who meet on a regular basis. The calculation of the value of the S&P Index, discussed below in further detail, is based on the relative value of the aggregate market value of specified classes of common stock of 500 companies (the “S&P Index Constituent Stocks”) as of a particular time 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 “Base Period”). The S&P Index Constituent Stocks do not represent the common stocks of the 500 largest companies listed on the New York Stock Exchange and not all 500 companies whose common stock are included in the S&P Index are listed on the New York Stock Exchange. Stocks are chosen for inclusion in the S&P Index by the S&P Index Committee with the goal of ensuring that the S&P Index is a leading indicator of United States equities (as determined below), reflecting the risk and return characteristics of the broader large cap universe on an ongoing basis.

Standard & Poor’s, a division of The McGraw-Hill Companies, Inc. (“S&P”), calculates the S&P Index by reference to the prices of the S&P Index Constituent Stocks without taking account of the value of dividends paid on such stocks. As a result, the return on the Securities will not reflect the return you would realize if you actually owned the stocks that compose the S&P Index and received the dividends paid on such stocks.

Stocks Included in the S&P Index

Only common stock of operating companies, real estate investment trusts (excluding mortgage REITs) and business development companies are eligible for inclusion in the S&P Index. The common stock of closed-end funds, holding companies, partnerships, investment vehicles and royalty trusts are not eligible for inclusion in the S&P Index. Further, for the common stock of a company to be eligible for inclusion in the S&P Index it must meet all of the following additional criteria, as determined by the S&P Index Committee in its sole discretion:

Ø Market Capitalization — Unadjusted market capitalization of US $3 billion or more. The ranges are reviewed from time to time by the S&P Index Committee to assure consistency with market conditions.

Ø Liquidity — Annual dollar value trade to market capitalization should be 0.3 or greater.

Ø Public Float — Public float of at least 50% of the common stock.

Ø Sector Classification — Contribution to the sector balance maintenance of the S&P Index.

Ø Financial Viability — Financial viability as generally measured for four consecutive quarters of positive as-reported earnings. Another measure of financial viability is a company’s balance sheet leverage, which should be operationally justifiable in the context of both its industry peers and its business model.

Ø Treatment of Initial Public Offerings — Initial public offerings should be seasoned for at least six to twelve months.

Ø United States Company — The company should be a United States company by either (i) meeting the following criteria: (A) incorporated in the United States, (B) financial reporting should be in U.S. GAAP, in U.S. dollars, and the company should not be considered a foreign entity by the United States Securities and Exchange Commission, (C) a corporate governance structure consistent with U.S. practice, (D) principal executive presence in the United States, (E) the United States portion of revenues, operations, fixed assets and employees should be a significant portion of the total, but not exceed 50%, (F) the common stock should be listed on the New York Stock Exchange, the American

IS-12

S&P 500^® Index

Stock Exchange, NASDAQ or NYSE Arca and (G) the company should generally be considered a United States company by analysts and investors, or (ii) meeting all but one of the criteria in subsection (i)(A)-(G) and there is no other major market beside the United States to which the company would logically be assigned.

Generally, only one class of common stock of any company is included in the S&P Index. The stock price and total shares outstanding of common stock of a company included in the S&P Index with more than one class of common stock outstanding is based on the most liquid class of common stock of that company as determined by S&P Index Committee in its sole discretion.

Criteria for Removal from the S&P Index

The common stock of a company may be removed from the S&P Index when the S&P Index Committee determines, in its sole discretion, that one of the following criteria is met:

Ø A company involved in a merger, acquisition or significant restructuring no longer meets the inclusion criteria, or

Ø A company substantially violates one more of the criteria for inclusion in the S&P Index, as described above.

Computation of the S&P Index

The calculation of the value of the S&P 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 approximately 500 companies as of a particular time as compared to the aggregate Market Value of the common stocks of approximately 500 similar companies during the Base Period. The “Market Value” of any S&P Index Constituent Stock is the product of the market price per share times the number of the then outstanding shares of such S&P Index Constituent Stock times an investable weight factor (“IWF”). An IWF is calculated for each S&P Index Constituent Stock so that the number of shares outstanding is reduced to exclude certain closely held shares from the determination of the level of the S&P Index.

The level of the S&P Index is calculated using a base-weighted aggregate methodology: the level of the S&P Index reflects the total Market Value of all the S&P Index Constituent Stocks relative to the Base Period. An indexed number is used to represent the results of this calculation in order make the value easier to work with and track over time. The actual total Market Value of the S&P Index Constituent Stocks in the S&P Index 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 Index is computed by dividing the total Market Value of the level of S&P Index Constituent Stocks by a number called the “S&P Divisor”. By itself, the S&P Divisor is an arbitrary number. However, in the context of the calculation of the level of the S&P Index, it is the only link to the original Base Period value of the S&P Index. Continuity in the S&P Index value is maintained by adjusting the S&P Divisor for certain events as described below.

Changes to the S&P Index are made on an as-needed basis. There is no annual or semi-annual reconstitution. Rather changes in response to corporate actions and market developments can be made at any time.

An adjustment to the S&P Divisor is required when any change to any S&P Index Constituent Stocks alters the total market value of the S&P Index while holding stock prices constant. S&P Divisor adjustments are made “after the close” meaning that after the close of trading the closing prices are used to calculate the new S&P Divisor based on whatever changes are being made. The table below summarizes the types of maintenance adjustments which require a divisor adjustment:

IS-13

S&P 500^® Index

Type of Corporate Action	Adjustment Factor
Company added / deleted	Net change in market value determines the S&P Divisor adjustment.
Spin-Off (Only if spun-off company added to S&P Index and another company deleted from S&P Index)	S&P Divisor adjustment reflects deletion of company from S&P Index.
Special Dividend	When a company pays a special dividend the share price is assumed to drop by the amount of the dividend.
Rights Offering	Increase in market capitalization measured as the shares issued multiplied by the price paid.

Each of the corporate actions in the table above has the effect of altering the market value of an S&P Index Constituent Stock and consequently the aggregate market value of the S&P Index Constituent Stocks. In order that the level of the S&P Index prior to such corporate action, not be affected by the change in market value of the S&P Index Constituent Stocks, a new S&P Divisor is derived as follows:

Ø Market value of the S&P Index Constituent Stocks after the corporate action / New S&P Divisor = Market Value of the S&P Index Constituent Stocks prior to the corporate action.

Ø New S&P Divisor = Market value of the S&P Index Constituent Stocks after the corporate action / Market Value of the S&P Index Constituent Stocks prior to the corporate action.

In cases where there is no achievable market price for a stock being deleted, such stock may be removed from the S&P Index at zero or minimal price at the discretion of the S&P Index Committee, in recognition of the constraints faced by investors in trading bankrupt or suspended stocks.

A large part of the maintenance of the S&P Index involves adjustments in response to changes in a company’s shares outstanding. The S&P Index Committee follows a 5% rule. Generally, changes in a company’s shares outstanding of 5% or more due to mergers, acquisitions, public offerings, private placements, tender offers, Dutch auctions or exchange offers are made as soon as reasonably possible. Other changes of 5% or more are made weekly. Changes of less than 5% of a company’s shares outstanding are accumulated and made quarterly on the third Friday of March, June, September and December, with the exception of an acquisition of another company in the S&P Index which are made as reasonably as possible. In the case of certain rights issuances, in which the number of rights issued and/or terms of their exercise are deemed substantial by the S&P Index Committee, a price adjustment and/or share increase may be implemented immediately.

The information in this description has been taken from (i) publicly available sources and (ii) a summary of the Dow Jones-AIG Commodity Index Handbook (a document that is considered proprietary to Dow Jones and AIG Financial Products Corp. (as successor in interest to AIG International Inc.) (“AIG-FP”) and is available to those persons who enter into a license agreement available at http://www.djindexes.com/aig/index.cfm?go=handbook). Such information reflects the policies of, and is subject to change by, Dow Jones & Company, Inc. (“Dow Jones”), AIG International Inc. (“AIGI”) and AIG-FP. UBS has not independently verified this information. You, as an investor in the Securities, should make your own investigation into the Indices, AIG-FP and Dow Jones. Dow Jones, AIG-FP and AIGI are not involved in the offer of the Securities in any way and have no obligation to consider your interests as a holder of the Securities. Dow Jones, AIG-FP and AIGI have no obligation to continue to publish the Indices, and may discontinue publication of either DJ-AIG Commodity Index at any time in their sole discretion.

Overview

The DJ-AIG Commodity Index was introduced in July 1998 to provide unique, diversified, economically rational and liquid benchmarks for commodities as an asset class. The DJ-AIG Commodity Index currently is composed of the prices of nineteen exchange-traded futures contracts on physical commodities. An exchange-traded futures contract is a bilateral agreement providing for the purchase and sale of a specified type and quantity of a commodity or financial instrument during a stated delivery month for a fixed price. For a general description of the commodity future markets, see “The Commodity Futures Markets” on page IS-22. The commodities included in the DJ-AIG Commodity Index for 2008 are as follows: aluminum, coffee, copper, corn, cotton, crude oil, gold, heating oil, lean hogs, live cattle, natural gas, nickel, silver, soybeans, soybean oil, sugar, unleaded gas (RBOB), wheat and zinc.

The DJ-AIG Commodity Index is a proprietary index that Dow Jones and AIGI developed and that Dow Jones, in conjunction with AIG-FP (as successor in interest to AIGI), calculates. The methodology for determining the composition and weighting of the DJ-AIG Commodity Index and for calculating its value is subject to modification by Dow Jones and AIG-FP at any time.

AIG-FP and its affiliates actively trade futures contracts and options on futures contracts on the commodities that underlie the DJ-AIG Commodity Index, as well as commodities, including commodities included in the DJ-AIG Commodity Index. AIG-FP and its affiliates also actively enter into or trade and market securities, swaps, options, derivatives and related instruments which are linked to the performance of commodities or are linked to the performance of the DJ-AIG Commodity Index. Certain of AIG-FP's affiliates may underwrite or issue other securities or financial instruments indexed to the DJ-AIG Commodity Index and related indices, and AIG-FP and Dow Jones and their affiliates may license the DJ-AIG Commodity Index for publication or for use by unaffiliated third parties. These activities could present conflicts of interest and could affect the level of the DJ-AIG Commodity Index. For instance, a market maker in a financial instrument linked to the performance of the DJ-AIG Commodity Index may expect to hedge some or all of its position in that financial instrument. Purchase (or selling) activity in the underlying DJ-AIG Commodity Index components in order to hedge the market maker's position in the financial instrument may affect the market price of the futures contracts included in the DJ-AIG Commodity Index, which in turn may affect the value of the DJ-AIG Commodity Index. With respect to any of the activities described above, none of AIG-FP, Dow Jones or their respective affiliates has any obligation to take the needs of any buyers, sellers or holders of the Securities into consideration at any time.

The Dow Jones-AIG Commodity Index Supervisory and Advisory Committees

Dow Jones and AIG-FP have established the Dow Jones-AIG Commodity Index Supervisory and Advisory Committees to assist them in connection with the operation of the commodity indices published by Dow Jones and AIG-FP, including the DJ-AIG Commodity Index. The Dow Jones-AIG Commodity Index Supervisory and Advisory Committees include prominent members of the financial, academic and legal communities selected by AIG-FP and Dow Jones and meet annually to consider any changes to be made to the indices for the coming year. The committees may also meet at such other times as may be necessary. The Supervisory Committee will make all final decisions relating to the Index, given any advice and recommendations of the Advisory Committee.

As described in more detail below, the DJ-AIG Commodity Index is reweighted and rebalanced each year in January on a price-percentage basis. The annual weightings for the DJ-AIG Commodity Index are determined each year in June or July by AIG-FP under the supervision of the Dow Jones-AIG Commodity Index Supervisory Committee. Following the Dow Jones-AIG Commodity Index Supervisory and Advisory Committees’ annual meetings in June or July, the annual weightings are publicly announced in July and take effect in January immediately following the announcement.

The Supervisory Committee has a significant degree of discretion in making determinations relating to the Index. The Supervisory Committee may exercise this discretion as it determines to be most appropriate.

Four Main Principles Guiding the Creation of the Dow Jones-AIG Commodity Index

The DJ-AIG Commodity Index was created using the following four main principles:

Ø Economic significance. A commodity index should fairly represent the importance of a diversified group of commodities to the world economy. To achieve a fair representation, the DJ-AIG Commodity Index uses both liquidity data and dollar-weighted production data in determining the relative quantities of included commodities.

The DJ-AIG Commodity Index primarily relies on liquidity data, or the relative amount of trading activity of a particular commodity, as an important indicator of the value placed on that commodity by financial and physical market participants. The DJ-AIG Commodity Index also relies on production data as a useful measure of the importance of a commodity to the world economy. Production data alone, however, may underestimate the economic significance of storable commodities (e.g., gold) relative to non-storable commodities (e.g., live cattle). Production data alone also may underestimate the investment value that financial market participants place on certain commodities, and/or the amount of commercial activity that is centered around various commodities. Additionally, production statistics alone do not necessarily provide as accurate a blueprint of economic importance as the pronouncements of the markets themselves. The DJ-AIG Commodity Index thus relies on data that is both endogenous to the futures market (liquidity) and exogenous to the futures market (production) in determining relative weightings.

Ø Diversification. A second major goal of the DJ-AIG Commodity Index is to provide diversified exposure to commodities as an asset class. Disproportionate weightings of any particular commodity or sector increase volatility and negate the concept of a broad-based commodity index. Instead of diversified commodities exposure, the investor is unduly subjected to micro-economic shocks in one commodity or sector. As described further below, diversification rules have been established and are applied annually. Additionally, the DJ-AIG Commodity Index is re-balanced annually on a price-percentage basis in order to maintain diversified commodities exposure over time.

Ø Continuity. The third goal of the DJ-AIG Commodity Index is to be responsive to the changing nature of commodity markets in a manner that does not completely reshape the character of the Index from year to year. The DJ-AIG Commodity Index is intended to provide a stable benchmark,

IS-17

Commodity Indices
Dow Jones-AIG Commodity Index^SM

so that end-users may be reasonably confident that historical performance data (including such diverse measures as correlation, spot yield, roll yield and volatility) is based on a structure that bears some resemblance to both the current and future composition of the DJ-AIG Commodity Index.

Ø Liquidity. Another goal of the DJ-AIG Commodity Index is to be highly liquid. The explicit inclusion of liquidity as a weighting factor helps to ensure that the indices can accommodate substantial investment flows. The liquidity of an index affects transaction costs associated with current investments. It also may affect the reliability of historical price performance data.

These principles represent goals of the DJ-AIG Commodity Index and its creators, and there can be no assurance that these goals will be reached by either Dow Jones or AIG-FP.

Composition of the DJ-AIG Commodity Index

Commodities Available for Inclusion in the DJ-AIG Commodity Index

The commodities that have been selected for possible inclusion in the DJ-AIG Commodity Index are believed by Dow Jones and AIG-FP to be sufficiently significant to the world economy to merit consideration for inclusion in the Indices, and each such commodity is the subject of a qualifying related futures contract (a “Designated Contract”).

With the exception of several London Metal Exchange (“LME”) contracts, where AIG-FP believes that there exists more than one futures contract with sufficient liquidity to be chosen as a Designated Contract for a commodity, AIG-FP selects the futures contract that is traded in North America and denominated in dollars. If more than one such contract exists, AIG-FP selects the most actively traded contract. This process is reviewed by the Supervisory and Advisory Committees. Data concerning this Designated Contract will be used to calculate the DJ-AIG Commodity Index. The termination or replacement of a futures contract on an established exchange occurs infrequently; if a Designated Contract were to be terminated or replaced, a comparable futures contract would be selected, if available, to replace that Designated Contract.

The 23 potential commodities that may be included in the DJ-AIG Commodity Index in a given year currently are aluminum, cocoa, coffee, copper, corn, cotton, crude oil, gold, heating oil, lead, cattle, hogs, natural gas, nickel, platinum, silver, soybeans, soybean oil, sugar, tin, unleaded gasoline, wheat and zinc.

Commodity Groups

For purposes of applying the diversification rules discussed above and below, the commodities available for inclusion in the DJ-AIG Commodity Index are assigned to Commodity Groups. The Commodity Groups currently include Energy, Precious Metals, Industrial Metals, Livestock, Grains and Softs.

Determination of Relative Weightings

The relative weightings of the component commodities included in the DJ-AIG Commodity Index are determined annually according to both liquidity and dollar-adjusted production data in -2/3 and -1/3 shares, respectively. Each June, for each commodity designated for potential inclusion in the DJ-AIG Commodity Index, liquidity is measured by the Commodity Liquidity Percentage (“CLP”) and production by the Commodity Production Percentage (“CPP”). The CLP for each commodity is determined by taking a five-year average of the product of trading volume and the historic dollar value of the Designated Contract for that commodity, and dividing the result by the sum of such products for all commodities which were designated for potential inclusion in the applicable index. The CPP is determined for each commodity by taking a five-year average of annual world production figures, adjusted by the historic dollar value of the Designated Contract, and dividing the result by the sum of such production figures for all the commodities which were designated for potential inclusion in the applicable index. The CLP and the CPP are then combined (using a ratio of 2:1) to establish the Commodity Index Percentage (“CIP”)

IS-18

Commodity Indices
Dow Jones-AIG Commodity Index^SM

for each commodity. This CIP is then adjusted in accordance with certain diversification rules in order to determine the commodities which will be included in each index (the “Index Commodities”) and their respective percentage weights.

Diversification Rules

The DJ-AIG Commodity Index is designed to provide diversified exposure to commodities as an asset class. To ensure that no single commodity or commodity sector dominates the DJ-AIG Commodity Index, the following diversification rules are applied to the annual reweighting and rebalancing of the DJ-AIG Commodity Index as of January of the applicable year:

Ø No related group of commodities designated as a Commodity Group may constitute more than 33% of the DJ-AIG Commodity Index.

Ø No single commodity may constitute more than 15% of the DJ-AIG Commodity Index.

Ø No single commodity, together with its derivatives (e.g., crude oil, together with heating oil and unleaded gasoline), may constitute more than 25% of the DJ-AIG Commodity Index.

Ø No single commodity that is in the DJ-AIG Commodity Index may constitute less than 2% of the DJ-AIG Commodity Index.

Following the annual reweighting and rebalancing of the DJ-AIG Commodity Index in January, the percentage of any single commodity or group of commodities at any time prior to the next reweighting or rebalancing will fluctuate and may exceed or be less than the percentages set forth above.

Commodity Index Multipliers

Following application of the diversification rules discussed above, CIPs are incorporated into the DJ-AIG Commodity Index by calculating the new unit weights for each DJ-AIG Commodity Index Commodity. Near the beginning of each new calendar year (the “CIM Determination Date”), the CIPs, along with the settlement prices on that date for Designated Contracts included in the DJ-AIG Commodity Index, are used to determine a Commodity Index Multiplier (“CIM”) for each DJ-AIG Commodity Index Commodity. This CIM is used to achieve the percentage weightings of the commodities included in the DJ-AIG Commodity Index, in dollar terms, indicated by their respective CIPs. After the CIMs are calculated, they remain fixed throughout the year. As a result, the observed price percentage of each DJ-AIG Commodity Index Commodity will float throughout the year, until the CIMs are reset the following year based on new CIPs.

Calculations

The DJ-AIG Commodity Index is calculated by Dow Jones, in conjunction with AIG-FP, by applying the impact of the changes to the futures prices of commodities included in the DJ-AIG Commodity Index (based on their relative weightings). Once the CIMs are determined as discussed above, the calculation of the Indices is a mathematical process whereby the CIMs for the commodities included in the DJ-AIG Commodity Index are multiplied by the prices in US dollars for the applicable Designated Contracts. These products are then summed. The percentage change in this sum is then applied to the prior DJ-AIG Commodity Index level to calculate the current DJ-AIG Commodity Index level. Dow Jones disseminates the DJ-AIG Commodity Index level approximately every fifteen seconds (assuming the DJ-AIG Commodity Index level has changed within such fifteen-second interval) from 8:00 a.m. to 3:00 p.m. (New York time), and publishes a daily DJ-AIG Commodity Index level at approximately 4:00 p.m. (New York time) on each DJ-AIG Business Day on Reuters page AIGCI1. DJ-AIG Commodity Index levels can also be obtained from the official websites of both Dow Jones and AIG-FP and are also published in The Wall Street Journal.

The DJ-AIG Commodity Index is a Rolling Index

The DJ-AIG Commodity Index is composed of futures contracts on physical commodities. Unlike equities, which typically entitle the holder to a continuing stake in a corporation, commodity futures contracts normally specify a certain date for the delivery of the underlying physical commodity. In order to avoid delivering the underlying physical commodities and to maintain exposure to the underlying physical commodities, periodically futures contracts on physical commodities specifying delivery on a nearby date must be sold and futures contracts on physical commodities that have not yet reached the delivery period must be purchased. The rollover for each contract occurs over a period of five DJ-AIG Business Days each month according to a pre-determined schedule. This process is known as “rolling” a futures position. The DJ-AIG Commodity Index is a “rolling index.”

DJ-AIG Commodity Index Calculation Disruption Events

From time to time, disruptions can occur in trading futures contracts on various commodity exchanges. The daily calculation of an index will be adjusted in the event that AIG-FP determines that any of the following index calculation disruption events exists:

(a) the termination or suspension of, or material limitation or disruption in the trading of any futures contract used in the calculation of the index on that day,

(b) the settlement price of any futures contract used in the calculation of the index reflects the maximum permitted price change from the previous day's settlement price,

(c) the failure of an exchange to publish official settlement prices for any futures contract used in the calculation of the index, or

(d) with respect to any futures contract used in the calculation of the DJ-AIG Commodity Index that trades on the LME, a business day on which the LME is not open for trading.

The Commodity Futures Markets

Contracts on physical commodities are traded on regulated futures exchanges, in the over-the-counter market and on various types of physical and electronic trading facilities and markets. At present, all of the contracts included in the DJ-AIG Commodity Index are exchange-traded futures contracts. An exchange-traded futures contract is a bilateral agreement providing for the purchase and sale of a specified type and quantity of a commodity or financial instrument during a stated delivery month for a fixed price. A futures contract on an index of commodities typically provides for the payment and receipt of a cash settlement based on the value of such commodities. A futures contract provides for a specified settlement month in which the commodity or financial instrument is to be delivered by the seller (whose position is described as “short”) and acquired by the purchaser (whose position is described as “long”) or in which the cash settlement amount is to be made.

There is no purchase price 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 may be as low as 5% or less of the value of the contract. This margin deposit provides collateral for the obligations of the parties to the futures contract.

By depositing margin in the most advantageous form (which may vary depending on the exchange, clearing house or broker involved), a market participant may be able to earn interest on its margin funds, thereby increasing the potential total return that may be realized from an investment in futures contracts. The market participant normally makes to, and receives from, the broker subsequent payments on a daily basis as the price of the futures contract fluctuates. These payments are called “variation margin” and make the existing positions in the futures contract more or less valuable, a process known as “marking to market.”

Futures contracts are traded on organized exchanges, known as “contract markets” in the United States, through the facilities of a centralized clearing house and a brokerage firm which is a member of the clearing house. The clearing house guarantees the performance of each clearing member which is a party to the futures contract by, in effect, taking the opposite side of the transaction. At any time prior to the expiration of a futures contract, subject to the availability of a liquid secondary market, a trader may elect to close out its position by taking an opposite position on the exchange on which the trade obtained the position. This operates to terminate the position and fix the trader's profit or loss.

U.S. contract markets, as well as brokers and market participants, are subject to regulation by the Commodity Futures Trading Commission. Futures markets outside the United States are generally subject to regulation by comparable regulatory authorities. However, the structure and nature of trading on non-U.S. exchanges may differ from the foregoing description. From its inception to the present, the DJ-AIG Commodity Index has been comprised exclusively of futures contracts traded on regulated exchanges.

We accept responsibility as to the correct reproduction of the information described in (ii) above. UBS has not independently verified information from publicly available sources, described above in clause (i). You, as an investor in the Securities, should make your own investigation into the CMCI Index.

However, employees of UBS AG, the issuer of the Securities, are members of the CMCI Index Committees and its affiliates are involved in the public offering and sale of the Securities and may be engaged in secondary market making transactions in the Securities.

Bloomberg L.P. and Reuters Group PLC (“Reuters”) have no obligation to continue to publish the CMCI Index, and may discontinue publication of the CMCI Index at any time in their sole discretion.

Overview of the CMCI and the CMCI Index

The CMCI Index was introduced in January 2007 to provide an innovative alternative to traditional commodity indices. The CMCI Index is based on the same methodology and contains the same components as the CMCI, which was also introduced in January 2007. Where the CMCI has weightings across commodities, the CMCI Index is weighted across both commodities and maturities. The CMCI Index represents a basket of 26 commodity futures contracts with a series of up to five different investment maturities for each individual commodity using the calculation methodology of constant maturity forwards. Traditional commodity indices tend to focus on front-month contracts with short tenors (time to maturity) whereas the CMCI Index is based on commodity futures contracts with tenors ranging from three months to three years. The CMCI Index also offers continuous roll mechanisms for each constant maturity with respect to each commodity futures contract, which, in contrast to rolling of front-month contracts offered in traditional commodity indices, offers the potential to mitigate negative roll yield. Roll yield arises from the differential between the price levels of the contracts that an index rolls out of and those it rolls into. The commodities represented in the CMCI Index currently include agricultural products, energy products, metals and minerals. The exchanges include the New York Mercantile Exchange (including the COMEX division), Chicago Board of Trade, London Metal Exchange, New York Board of Trade, Chicago Mercantile Exchange, ICE Futures and Euronext.Liffe.

The CMCI Index was developed by UBS and Bloomberg. The CMCI Index is calculated and disseminated by UBS approximately every fifteen seconds (assuming the level of the CMCI Index has changed within such fifteen-second interval) from 8:00 a.m. to 3:00 p.m., New York City time, and a daily index level for the CMCI Index is published between 4:00 p.m. and 6:00 p.m., New York City time on each trading day. CMCI Index information is available under the symbol “CMCIER” from Bloomberg on pages CUBS + GO, CMCN or CMCX and from Reuters on page UBSCMCI.

The CMCI Index Committees

All decisions related to the CMCI Index are made by the CMCI Governance Committee, which is comprised of eight people: four appointed by each CMCI Index Sponsor. Each CMCI Index Sponsor, in

IS-23

The UBS Bloomberg Constant Maturity Commodity Index (CMCI)

turn, appoints a chairman from the members of the CMCI Governance Committee who serves for a period of six months. Each representative on the CMCI Governance Committee has one vote, with the chairman having an additional vote in the event of a tie. The CMCI Governance Committee holds ordinary meetings bi-annually around the second Friday of May and November.

The CMCI Governance Committee is advised by the CMCI Advisory Committee, which is comprised of experts including trading, research and structuring representatives, a secretary and a legal advisor. The CMCI Advisory Committee provides relevant market data and recommends appropriate changes to the CMCI Index. The CMCI Advisory Committee may also request special meetings of the CMCI Governance Committee in the case of market emergencies or where the CMCI Advisory Committee feels a special meeting is necessary. Ultimately, the decisions of the CMCI Governance Committee must be reviewed and, if approved, implemented by the CMCI Index Sponsors themselves. In this regard, the CMCI Index Sponsors will each be represented by an appointee who is a board member (or Managing Director) of the relevant CMCI Index Sponsor.

CMCI Index Composition

The Selection Process

In order to be eligible for inclusion in the CMCI Index, a commodity future contract must satisfy certain requirements as described below. Changes in the CMCI Index’s composition, as described herein, are entirely a function of those made to the CMCI by the CMCI Governance Committee. No decision can be made to add or withdraw a CMCI Index component or affect the weight of such component independently from those made with respect to the CMCI.

Generally, when a contract becomes eligible for inclusion in the CMCI Index, and the CMCI Governance Committee believes that such inclusion is appropriate in light of the CMCI Index procedures and objectives, changes in the CMCI Index composition would be reviewed in May and/or November by the CMCI Governance Committee, with changes effected during the following maintenance period of July and/or January.

The CMCI Index’s composition is modified only in rare occasions, in order to maintain liquidity and stability of the CMCI Index, and the composition of the CMCI Index generally will not be changed unless “extraordinary circumstances” in fact occur. Such extraordinary circumstances may include (but are not limited to):

Ø declining or rising trading volumes, instrument delisting or creation (when declining trading volumes are posing a threat to the CMCI stability and tradability),

Ø critical changes in commodity production or consumption patterns,

Ø changes in foreign exchange regimes,

Ø general macroeconomic or political events, and

Ø all types of legal changes, tax rulings and official decisions presenting a threat to CMCI investors and/or CMCI Index Sponsors.

In some special situations likely to affect the CMCI Index adversely and reflect negatively on investors and/or members of the CMCI Governance Committee, the CMCI Governance Committee, in consultation with the CMCI Advisory Committee, can also declare “force majeure” and can change any parameter of the CMCI Index with immediate effect. The CMCI Index Sponsors also reserve the right to alter the procedures and methodology related to selecting the underlying futures contracts.

IS-24

The UBS Bloomberg Constant Maturity Commodity Index (CMCI)

Component Selection and Target Weights

For a commodity contract to be included in the CMCI Index, the following primary and secondary requirements have to be satisfied:

Ø The “primary requirements” are related to the nature of the instrument as well as some technical characteristics including country of origin, trading characteristics, foreign exchange controls and availability and accuracy of contract, price and volume data.

Ø The “secondary requirements” involve satisfying a series of pure financial thresholds based on liquidity, including, among other things, open interest and market volume. Open interest, which reflects positions in contracts that remain open on an overnight or multi-day basis, is used to assess past and future liquidity. Market volume, which reflects the number of contracts traded in a given period of time, indicates immediate interest, and over a period of time provides a usable measure of liquidity.

CMCI Index Weightings

Initial Weightings

The weighting process for the CMCI Index is designed to reflect the economic significance and market liquidity of each commodity. The CMCI Index Sponsors use a two step approach to determining target weights of the futures contracts in the CMCI Index. First, the CMCI Index Sponsors use regional Consumer Price Indexes (CPI), Producer Price Indexes (PPI) and Gross Domestic Product (GDP) data to produce the Economic Weight (EW) of each of the five sectors of the CMCI Index — the five sectors of the CMCI Index are currently agriculture, livestock, energy, precious metals and industrial metals. Second, the market value of the amount of each commodity that is consumed is used to calculate the individual instrument weight of each commodity, based on such market value as a percentage of the total market value of the consumption of all commodities included in the relevant sector.

Changes in the Weights and/or CMCI Index Composition

As noted above, the CMCI Governance Committee (in consultation with the CMCI Advisory Committee) reviews the selection and weightings of the futures contracts in the CMCI Index bi-annually, in November and May, or at any special meeting called by the CMCI Advisory Committee. Thus, weights are potentially reassigned whenever a regular or special meeting of the CMCI Governance Committee is held, subject to ratification by the CMCI Index Sponsors.

Continuous Rolling of Contracts

The CMCI Index represents a weighted average of all available CMCI constant maturities (ranging from three months to three years). The distribution of weightings to available tenors (time to maturity) is a function of relative liquidity of the underlying futures contracts. As with most asset classes, the liquidity of commodity futures contracts tends to reduce as time to maturity increases. Therefore, the continuous rolling (constant maturity) of the CMCI Index limits the dilution of liquidity of the underlying commodity futures contracts. In this way, the CMCI Index reflects the most liquid contracts.

Rebalancing of the CMCI Index Components

Because of price movements, the weight of each commodity in the CMCI Index will move away from its target weight over time. The weight of each CMCI Index component is therefore rebalanced over the final three business days of each month in order to bring each commodity back to its target weight. The process is automatic and is implemented via a pre-defined algorithm.

In addition, twice annually in January and July there is a maintenance period at which time the target weights themselves are adjusted according to decisions of the CMCI Governance Committee.

IS-25

The UBS Bloomberg Constant Maturity Commodity Index (CMCI)

Market Disruption

As noted above, the CMCI Advisory Committee will request extraordinary meetings with the CMCI Governance Committee in the event of actual or potential “market emergency” or “force majeure” events (as discussed below), or any other situations the CMCI Advisory Committee deems, in its own discretion, to require an extraordinary meeting. The purpose of such meetings will be to determine what, if any, changes to make to the CMCI Index.

Market Emergency and Force Majeure

In some extraordinary circumstances, the CMCI Governance Committee, in consultation with the CMCI Advisory Committee, can deem an event a “market emergency and force majeure” event. Such extraordinary circumstances include:

Ø the imposition of a currency control mechanism,

Ø the adoption or issuance of tax-related rules, regulations, orders or other actions,

Ø an announcement or other public action regarding scientific discoveries or events relating to the commodities markets,

Ø a governmental, regulatory or other public announcement that is reasonably likely to affect the commodity markets generally,

Ø any climate or weather related emergencies,

Ø a war,

Ø a terrorist event,

Ø any event other than those specifically identified herein, making the calculation of the CMCI Index impossible or infeasible either on a technical basis or otherwise, or that makes the CMCI Index non representative of market prices or undermines the realization of the objectives of the Index, and

Ø any event creating a situation of unfair advantage or disadvantage for any market participant, group of market participants or the CMCI Index Sponsors.

Whenever a “market emergency and force majeure” event has been identified, the CMCI Governance Committee, in consultation with the CMCI Advisory Committee, can take any action it deems appropriate, including, but not limited to:

Ø the replacement of a daily component nearby price when there is a manifest error in the officially settled price or when a market abuse is likely to have taken place,

Ø the temporary or final revoking of the membership of a component in the CMCI Index,

Ø the immediate change of a CMCI Index parameter,

Ø the suspension of the calculation of the CMCI Index, a sub CMCI Index, a standard constant maturity series, or a currency series, or

Ø in general, any action necessary to preserve the reputation of the CMCI Index as a fair and tradable commodity benchmark.

Adjustments for “Market Disruption Event Day”

When an exchange fails to publish a settlement price for components involved in any of the CMCI Index maintenance procedures (rebalancing or re-weighting), the CMCI Index business day is deemed a “market disruption event day.” The components involved are not rolled or rebalanced on that day. For those contracts or components, the roll periods remain identical to the value they had on the CMCI Index business day immediately preceding the “market disruption event day” in such a way that the

IS-26

The UBS Bloomberg Constant Maturity Commodity Index (CMCI)

maintenance period is extended for as long as no settlement price is made available by the affected exchange. If, after a period of five standard business days, no settlement price has been made available by the exchange or trading platform, the CMCI Index Sponsors will determine, in good faith, taking into account the objectives of the CMCI Index and the interests of market participants, the one or more exchange settlement or official closing prices necessary for the maintenance of the component and the calculation of the CMCI Index.

Adjustments for “FX Market Disruption Event Day”

In the event of a reference price source failing to publish a valid fixing rate for a referenced currency exchange rate, the CMCI Index business day is deemed an “FX market disruption event day.” If no fixing price has been made available by the affected price source, the one or more foreign exchange currency rate fixing prices necessary for the calculation of the CMCI Index will be obtained by the CMCI Index Sponsors from commercially reasonable sources in the market, or determined in good faith, bearing in mind both the interest of investors and market participants, and with the aim of maintaining and enhancing the CMCI Index as a tradable commodity investment benchmark. A commercially reasonable method would be, for example, the averaging of three foreign exchange broker-dealer quotes at the approximate time when the fixing would have been determined by the price source. In the event that the rate source becomes permanently deficient, the CMCI Governance Committee, in consultation with the CMCI Advisory Committee, may characterize the event as a “force majeure” event and decide to replace it by a new source effective immediately thereafter.

CMCI Index information is available on the Bloomberg website: http://www.bloomberg.com (Select “COMMODITIES” from the drop-down menu entitled “Market Data”). For further information on CMCI, investors can go to http://www.ubs.com/cmci. Index values can also be found at http://www.ubs.com/keyinvest, choose “United States” and then click on the “Commodities” tab.

Excess Return vs. Total Return

The CMCI Index reflects the returns that are potentially available through an uncollateralized investment in the CMCI basket. The term “Excess Return” in the title of the CMCI Index is not intended to suggest that the performance of the CMCI Index at any time or the return on your Securities will be positive or that the CMCI Index is designed to exceed a particular benchmark.

Overview

The Rogers Index was developed by Rogers and launched on July 31, 1998. The Rogers Index is a composite U.S. dollar-based commodity futures index that is designed to serve as a diversified benchmark for the price movements of commodities consumed in the global economy. The Rogers Index is composed of futures contracts on 36 physical commodities traded on ten exchanges in five countries and quoted in four different currencies. The commodities represented in the Rogers Index range from agricultural products to energy and metals products. The commodities futures contracts are quoted in U.S. dollars, Canadian dollars, Japanese yen and Australian dollars.

The Rogers Index aims to be an effective measure of the price action of raw materials not just in the United States but also around the world. The Rogers Index's weightings attempt to balance consumption patterns worldwide (in developed and developing countries) and specific contract liquidity.

The Index Committee

The Rogers Index Committee (the “Index Committee”) formulates and enacts all business assessments and decisions regarding the calculation, composition and management of the Rogers Index. Rogers, as the founder of the Rogers Index, chairs the Index Committee. In addition to Rogers, representatives of the following institutions are members of the Index Committee: (1) Diapason, (2) Daiwa Asset Management America, (3) Beeland Management Company, (4) UBS, (5) ABN AMRO and (6) Merrill Lynch. Exclusively Rogers, as chairman of the committee, is authorized to designate new members of the committee, if necessary.

The Index Committee usually meets each December to consider changes in the components and weightings of the Rogers Index for the following calendar year; however, such changes can be made at any time if severe circumstances (as defined below) occur.

IS-28

Rogers International Commodity Index^® Excess Return^SM

Rogers Index Composition

The Process

The contracts chosen for the basket of commodities that constitute the Rogers Index are required to fulfill various conditions described below. Generally, the selection and weighting of the items in the Rogers Index are reviewed annually by the Index Committee, and weights for the next year are assigned every December.

The Rogers Index's composition is modified in order to maintain liquidity and stability, and the composition of the Rogers Index generally will not be changed unless severe circumstances occur. Such “severe circumstances” may include (but are not restricted to):

Ø continuous adverse trading conditions for a single contract (e.g., trading volume collapses), or

Ø critical changes in the global consumption pattern (e.g., scientific breakthroughs that fundamentally alter consumption of a commodity).

Exchanges and Non-Traded Items

All commodities included in the Rogers Index must be publicly traded on recognized exchanges in order to ensure ease of tracking and verification. The 15 international exchanges recognized by the Index Committee are:

1. Chicago Mercantile Exchange (U.S.)	8. Sydney Futures Exchange (Australia)
2. Chicago Board of Trade (U.S.)	9. Fukuoka Futures Exchange (Japan)
3. New York Board of Trade (U.S.)	10. Central Japan Commodity Exchange (Japan)
4. New York Mercantile Exchange (U.S.)	11. Osaka Mercantile Exchange (Japan)
5. Winnipeg Commodity Exchange (Canada)	12. The Tokyo Commodity Exchange (Japan)
6. International Petroleum Exchange (UK)	13. Tokyo Grain Exchange (Japan)
7. London Metal Exchange (UK)	14. Yokohama Commodity Exchange (Japan).
	15. Intercontinental Exchange (UK)

General Contract Eligibility

A commodity may be considered suitable for inclusion in the Rogers Index if it plays a significant role in worldwide (developed and developing economies) consumption. “Worldwide consumption” is measured by tracking international import and export patterns, and domestic consumption environments of the world's prime commodity consumers. Only raw materials that reflect the current state of international trade and commerce are eligible to become Rogers Index commodities. Commodities that are merely linked to national consumption patterns will not be considered. The Rogers Index is not related to any commodities production data.

Commodity Screening Process

Data of private and governmental providers concerning the world's top consumed commodities is actively monitored and analyzed by the members of the Index Committee throughout the year. In order to obtain the most accurate picture of international commodities consumption, a wide range of sources on commodities demand and supply is consulted. The findings of this research are then condensed into the different commodities contracts weightings of the Rogers Index. Sources on global commodity consumption data include:

Ø Industrial Commodity Statistics Yearbook, United Nations (New York, NY, United States)

Ø Commodity Trade Statistics Database, United Nations Statistic Division (New York, NY, United States)

Ø Copper Bulletin Yearbook, International Copper Study Group (Lisbon, Portugal)

Ø Manufactured Fiber Review, Fiber Economics Bureau, Inc. (Arlington, VA, United States)

Ø Monthly Bulletin, International Lead and Zinc Study Group (London, England)

Ø Quarterly Bulletin of Cocoa Statistics, International Cocoa Organization (London, England)

Ø Rubber Statistical Bulletin, International Rubber Study Group (London, England)

Ø Statistical Bulletin Volumes, Arab Gulf Cooperation Council (Riyadh, Saudi Arabia)

Ø Sugar Yearbook, International Sugar Organization (ISO) (London, England)

Ø World Commodity Forecasts, Economist Intelligence Unit (London, England)

Ø World Cotton Statistics, International Cotton Advisory Committee (Washington, D.C., United States)

Ø World Metals Statistics, World Bureau of Metal Statistics (London, England)

Contract Characteristics

In order to decide whether a specific commodity contract is actually investable, the Index Committee screens the volume and liquidity data of international exchanges, published on a regular basis by the Futures Industry Association (Washington, D.C., United States). Additionally, individual exchange data on contracts may also be included in the process.

If a commodity contract trades on more than one exchange, the most liquid contract globally, in terms of volume and open interest combined, is then selected for inclusion in the Rogers Index, taking legal considerations into account. Beyond liquidity, the Index Committee seeks to include the contract representing the highest quality grade of a specific commodity.

Rogers Index Weightings

As of the date of this index supplement, the Rogers Index components have the initial weightings listed in the following chart (the “Initial Weightings”). The Initial Weightings may be amended from time to time, as described below.

Commodity	Allocation

Changes in Weights and/or Rogers Index Composition

The Index Committee reviews the selection and weighting of the futures contracts in the Rogers Index annually. Thus, weights are potentially reassigned during each month of December for the following year, if the Index Committee so determines in its sole discretion.

Monthly Rolling of Contracts

The Rogers Index utilizes a three-day roll period generally beginning on the day prior to the last business day of each month and ending on the first business day of each following month. Generally, if the next calendar month of a futures contract includes a first notice day, a delivery day or historical evidence that liquidity migrates to a next contract month during this period, then the next contract month is intended to be applied to calculate the Rogers Index, taking legal constraints into account. For example, on the close of the last business day of November, the January crude oil contract is replaced by the February crude oil contract. If the exchange on which one of the Rogers Index components is closed the last business day of the month, the roll of this specific contract takes place the next business day for that exchange.

Rebalancing of the Rogers Index Components

On the close of the last business day of each month, the current weight of each Rogers Index component is rebalanced in order to be set at its Initial Weighting. If the exchange on which one of the Rogers Index components is traded is closed on the last business day of the month, the reference price for the

IS-31

Rogers International Commodity Index^® Excess Return^SM

calculation of the weighting of this specific component is the closing price of the next business day. This rule is also valid if there is more than one component that cannot be traded on the last business day of the month.

Data Source

The Rogers Index calculation is based on the official commodity exchanges' prices of the futures contracts used.

Market Disruption

If, for any reason, one of the Rogers Index components ceases to exist or its liquidity collapses to unacceptable levels, or any other similar event occurs with similar consequences, as determined at the discretion of the Index Committee, the Index Committee will call an exceptional meeting to assess the situation and decide on a replacement for this component or on a change in the weighting. For example, following a currency board on the Malaysian ringgit in 1998, the liquidity of the palm oil futures contract on the Kuala Lumpur Commodity Exchange collapsed to a point where it became impossible to trade it. In that case, the Index Committee, calling an exceptional meeting, decided to replace the palm oil futures contract with the soybean oil contract that trades on the Chicago Board of Trade.

Reference Rates

The foreign exchange rates used to translate the value of the futures contracts denominated in a foreign currency into U.S. dollars are obtained from Bloomberg. This is the “close” value for each currency taken at 5:00 p.m. New York time.

Calculation of the Rogers Index

Diapason is responsible for calculating the Rogers Index and disseminating quotes of the Rogers Index continuously from 8:30 a.m. to 8:30 p.m. Central European Time on the Rogers Index business days.

Excess Return vs. Total Return

The Rogers Index reflects the returns that are potentially available through an unleveraged investment in the futures contracts on physical commodities composing the Rogers Index. The Rogers International Commodity Index^® (Total Return), a “total return” index, reflects those returns as well as any interest that could be earned on cash collateral invested in 3-month treasury bills. The term “Excess Return” in the title of the Rogers Index is not intended to suggest that the performance of the Rogers Index at any time or the return on your Securities will be positive or that the Rogers Index is designed to exceed a particular benchmark.

AMEX Hong Kong 30 Index

The AMEX Hong Kong 30 Index (the “HK Index”), a service mark of the HK Index Sponsor, is a capitalization-weighted stock index designed, developed, maintained and operated by the American Stock Exchange, Inc. (“the HK Index Sponsor”) that measures the market value performance (share price times the number of shares outstanding) of selected stocks listed on The Stock Exchange of Hong Kong Ltd. (the “HKSE”). The HK Index is reported by Bloomberg Financial Markets under the ticker symbol “HKX”. The HK Index currently is based on the capitalization of 30 stocks actively traded on the HKSE and is designed to represent a substantial segment of the Hong Kong stock market. As of January 6, 2009, the two largest stocks underlying the HK Index, China Mobil and HSBC Holdings, together account for over 53% of the HK Index’s weight. The primary trading market for all of these stocks is either Hong Kong or London. Business sector representation of the stocks comprising the HK Index as of January 6, 2009 consists primarily of finance, energy, property development, utilities and conglomerates, and also includes hotel/leisure, property investment, airlines, transportation and retail. The HK Index was established on June 25, 1993.

The HK Index is maintained by the HK Index Sponsor and will contain at least 30 stocks at all times. In addition, the stocks must meet certain listing and maintenance standards as discussed below. The HK Index Sponsor may change the composition of the HK Index at any time in order to more accurately reflect the composition and track the movement of the Hong Kong stock market. Any replacement stock must also meet the stock listing and maintenance standards as discussed below. Further, the HK Index Sponsor may replace stocks in the event of certain corporate events, such as takeovers or mergers, that change the nature of the security. The HK Index Sponsor selects stocks comprising the HK Index on the basis of their market weight, trading liquidity and representation of the business industries reflected on the HKSE. The HK Index Sponsor requires that each stock be one issued by an entity with major business interests in Hong Kong, be listed for trading on the HKSE and have its primary trading market located in a country with which the HK Index Sponsor has an effective surveillance sharing agreement. The HK Index Sponsor will remove any stock failing to meet the above listing and maintenance criteria within 30 days after such failure occurs. In order to ensure that the HK Index does not contain a large number of thinly capitalized, low-priced securities with small public floats and low trading volumes, the HK Index Sponsor has also established additional qualification criteria for the inclusion and maintenance of stocks, based on the following standards: all stocks selected for inclusion in the HK Index must have, and thereafter maintain, (1) an average daily capitalization, as calculated by the total number of shares outstanding times the latest price per share (in Hong Kong dollars), measured over the prior 6-month period, of at least H.K.$3,000,000,000; (2) an average daily closing price, measured over the prior 6-month period, not lower than H.K.$2.50; (3) an average daily trading volume, measured over the prior 6-month period, of more than 1,000,000 shares per day, although up to, but no more than, three stocks may have an average daily trading volume, measured over the prior 6-month period, of less than 1,000,000 shares per day, but in no event less than 500,000 shares per day; and (4) a minimum “free float” value (total freely tradable outstanding shares minus insider holdings), based on a monthly average measured over the prior 3-month period, of U.S.$238,000,000, although up to, but no more than, three stocks may have a free float value of less than U.S.$238,000,000 but in no event less than U.S.$150,000,000, measured over the same period.

The HK Index Sponsor reviews and applies the above qualification criteria relating to the stocks comprising the HK Index on a quarterly basis, conducted on the last business day in January, April, July and October. Any stock failing to meet the above listing and maintenance criteria will be reviewed on the second Friday of the second month following the quarterly review to again determine compliance with the above criteria. Any stock failing this second review will be replaced by a “qualified” stock effectiveupon the close of business on the following Friday, provided, however, that if such Friday is not a

IS-35

Non-U.S. Indices
AMEX Hong Kong 30 Index

New York business day, the replacement will be effective at the close of business on the first preceding New York business day. The HK Index Sponsor will notify its membership immediately after it determines to replace a stock.

The annual reports and prospectuses of the companies listed on the HKSE are available for investors’ inspection in the City Hall Library (a public library in Hong Kong, Central). A company whose stock is included in the HK Index is not required to be incorporated under the laws of Hong Kong.

The HK Index is a capitalization-weighted index. A company's market capitalization is calculated by multiplying the number of shares outstanding by the company's current share price (in Hong Kong dollars). For valuation purposes, one HK Index unit is assigned a fixed value of one U.S. dollar. The HK Index measures the average changes in price of the stocks comprising the HK Index, weighted according to the respective market capitalizations, so that the effect of a percentage price change in a stock will be greater the larger the stock's market capitalization. The HK Index was established by the HK Index Sponsor on June 25, 1993, on which date the HK Index value was set at 350.00. The daily calculation and public dissemination by the HK Index Sponsor of the HK Index value commenced on September 1, 1993. The data relating to the HK Index was back-calculated by the HK Index Sponsor from January 2, 1989 to August 31, 1993.

The HK Index is calculated by (i) aggregating the market capitalization of each stock comprising the HK Index and (ii) dividing such sum by an adjusted base market capitalization or divisor. On June 25, 1993, the market value of the Underlying Stocks was approximately H.K.$1,152,829,149,500 and the divisor used to calculate the HK Index was 3,293,797,570. The HK Index Sponsor selected that particular divisor number in order, among other things, to ensure that the HK Index was set at a general price level consistent with other well recognized stock market indices. The divisor is subject to periodic adjustments as set forth below. The HK Index is calculated once each day by the HK Index Sponsor based on the most recent official closing prices of each of the stocks comprising the HK Index reported by the HKSE. Pricing of the HK Index is disseminated before the opening of trading via the Consolidated Tape Authority Network-B and continuously during each New York business day. The dissemination value, however, will remain the same throughout the trading day because the trading hours of the HKSE do not overlap with New York trading hours. Accordingly, updated price information will be unavailable.

In order to maintain continuity in the level of the HK Index in the event of certain changes due to nonmarket factors affecting the stocks comprising the HK Index, such as the addition or deletion of stocks, substitution of stocks, stock dividends, stock splits, distributions of assets to stockholders or other capitalization events, the divisor used in calculating the HK Index is adjusted in a manner designed to prevent any instantaneous change or discontinuity in the level of the HK Index and in order that the value of the HK Index immediately after such change will equal the level of the HK Index immediately prior to the change. Thereafter, the divisor remains at the new value until a further adjustment is necessary as the result of another change. Nevertheless, changes in the identities and characteristics of the stocks comprising the HK Index may significantly affect the behavior of the HK Index over time.

Unless otherwise stated, all information contained herein on the HK Index is derived from publicly available sources. Such information reflects the policies of the HK Index Sponsor as stated in such sources and such policies are subject to change by the HK Index Sponsor. The HK Index Sponsor has no obligation to continue to publish, and may discontinue publication of, the HK Index at any time. We do not assume any responsibility for the accuracy or completeness of such information. Future performance of the HK Index may differ significantly from historical performance, either positively or negatively.

The Stock Exchange of Hong Kong Ltd (“HKSE”).

The HKSE is a wholly-owned subsidiary of Hong Kong Exchanges and Clearing Limited. Trading on the HKSE is fully electronic through an Automatic Order Matching and Execution System, which was

IS-36

Non-U.S. Indices
AMEX Hong Kong 30 Index

introduced in November 1983. The system is an electronic order book in which orders are matched and executed instantaneously if there are matching orders in the book, and on the basis of time/price priority. On-line real-time order entry and execution have eliminated the previous limitations of telephone-based trading. Trading takes place through trading terminals on the trading floor or through the off-floor trading devices at HKSE participants’ offices. Trading is conducted from 10:00 a.m. to 4:00 p.m. (Hong Kong time) every Hong Kong day except Saturdays, Sundays and other days on which the HKSE is closed. Hong Kong time is 12 hours ahead of Eastern Daylight Savings Time and 13 hours ahead of Eastern Standard Time. Settlement of trade is required within 48 hours and is conducted by electronic book-entry delivery through the Central Clearing and Settlement System.

Due to the time differences between New York City and Hong Kong, on any normal trading day, trading on the HKSE currently will cease at 3:00 a.m. or 4:00 a.m., New York City time. Using the last reported closing prices of the stocks underlying the HK Index on the HKSE, the closing level of the HK Index on any such trading day generally will be calculated, published and disseminated by the HK Index Sponsor in the United States shortly before the opening of trading on the American Stock Exchange in New York on the same calendar day.

The HKSE has adopted certain measures intended to prevent any extreme short-term price fluctuations resulting from order imbalances or market volatility. Where the HKSE considers it necessary for the protection of the investor or the maintenance of an orderly market, it may at any time suspend dealings in any securities or cancel the listing of any securities in such circumstances and subject to such conditions as it thinks fit, whether requested by the listed issuer or not. The HKSE may also do so where: (1) an issuer fails, in a manner which the HKSE considers material, to comply with the HKSE Listing Rules or its Listing Agreements; (2) the HKSE considers there are insufficient securities in the hands of the public; (3) the HKSE considers that the listed issuer does not have a sufficient level of operations or sufficient assets to warrant the continued listing of the issuer's securities; or (4) the HKSE considers that the issuer or its business is no longer suitable for listing. Investors should also be aware that the HKSE may suspend the trading of individual stocks in certain limited and extraordinary circumstances, until certain price-sensitive information has been disclosed to the public. Trading will not be resumed until a formal announcement has been made. Trading of a company's shares may also be suspended if there is unusual trading activity in such shares.

An issuer may apply for suspension of its own accord. A suspension request will normally only be acceded to in the following circumstances: (1) where, for a reason acceptable to the HKSE, price-sensitive information cannot at that time be disclosed; (2) where the issuer is subject to an offer, but only where terms have been agreed in principle and require discussion with, and agreement by, one or more major shareholders (suspensions will only normally be appropriate where no previous announcement has been made); (3) to maintain an orderly market; (4) where there is an occurrence of certain levels of notifiable transactions, such as substantial changes in the nature, control or structure of the issuer, where publication of full details is necessary to permit a realistic valuation to be made of the securities concerned, or the approval of shareholders is required; (5) where the issuer is no longer suitable for listing, or becomes a “cash” company; or (6) for issuers going into receivership or liquidation. As a result of the foregoing, variations in the HK Index may be limited by suspension of trading of individual stocks which comprise the HK Index which may, in turn, adversely affect the value of the Securities.

Dow Jones EURO STOXX 50^® Index

The Dow Jones EURO STOXX 50^® Index (the “EURO STOXX 50 Index”) seeks to provide exposure to large capitalization equity securities in the Eurozone. The EURO STOXX 50 Index is maintained and published by STOXX Limited (the “EURO STOXX 50 Index Sponsor”). The EURO STOXX 50 Index covers 50 stocks of market sector leaders mainly from 12 Eurozone countries: Austria, Belgium, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, the Netherlands, Portugal and Spain. The EURO STOXX 50 Index captures approximately 60% of the free float market capitalization of the Dow Jones EURO STOXX Total Market Index (TMI) (the “Dow Jones STOXX TMI”), which in turn covers approximately 95% of the free float market capitalization of the stocks traded on the major exchanges of the 12 Eurozone countries. The EURO STOXX 50 Index universe is defined as all components of the 19 Dow Jones EURO STOXX Supersector indices. The Dow Jones EURO STOXX Supersector indices represent the Eurozone portion of the Dow Jones STOXX 600 Supersector indices, which indices contain the 600 largest stocks traded on the major exchanges of 18 European counties.

For each of the 19 Dow Jones EURO STOXX Supersector indices, the component stocks are ranked by free-float market capitalization. The largest stocks are added to the selection list until the coverage is close to, but still less than, 60% of the free-float market capitalization of the corresponding Dow Jones STOXX TMI Supersector index. If the next-ranked stock brings the coverage closer to 60% in absolute terms, then it is also added to the selection list.

Any remaining stocks that are currently components of the EURO STOXX 50 Index are added to the selection list. The stocks on the selection list are ranked by free-float market capitalization. In exceptional cases, the EURO STOXX 50 Index Sponsor’s Supervisory Board may make additions and deletions to the selection list.

The 40 largest stocks on the selection list are chosen as components. Any remaining current components of the EURO STOXX 50 Index ranked between 41 and 60 are added as EURO STOXX 50 Index components. If the component number is still below 50, then the largest stocks on the selection list are added until the EURO STOXX 50 Index contains 50 stocks. The EURO STOXX 50 Index composition is reviewed annually in September and is subject to change.

The EURO STOXX 50 Index is weighted by free-float market capitalization. Each component’s weight is capped at 10% of the EURO STOXX 50 Index’s total free-float market capitalization. Weights are reviewed quarterly and are also subject to change in response to specific events affecting the EURO STOXX 50 Index component stocks, including initial public offerings, mergers and takeovers, spin-offs, de-listings and bankruptcy. The EURO STOXX 50 Index is calculated with the Laspeyres formula, which measures price changes against a fixed base quantity weight. The EURO STOXX 50 Index is also subject to a divisor, which is adjusted to maintain the continuity of the EURO STOXX 50 Index’s values across changes due to certain corporate actions.

The EURO STOXX 50 Index is denominated in Euros. The EURO STOXX 50 Index return will be calculated based on the closing levels of the EURO STOXX 50 Index, as reported by Bloomberg L.P. under ticker symbol “SX5E.”

The FTSE^TM 100 Index

The FTSE 100 Index (the “FTSE 100 Index”) was developed with a base value of 1,000 as of January 3, 1984. The FTSE 100 Index is a market capitalization-weighted index and consists of the 100 most highly capitalized UK-domiciled companies traded on the SETS trading system of the London Stock Exchange (the “Exchange”). To qualify, companies must have a full listing on the Exchange with a Sterling or Euro denominated price on the Exchange’s SETS trading system, subject to eligibility screens. The FTSE Europe/Middle East/Africa Regional (“EMEA”) Committee meets quarterly, on the Wednesday after the first Friday in March, June, September and December, to review the constituents of the FTSE 100 Index.

A security will be inserted in the FTSE 100 Index at the periodic review if it rises to or above the 90^th position when the eligible securities are ranked by market value. Consequently, a security will be deleted from the FTSE 100 Index at the periodic review if it falls to or below the 111^th position. A constant number of constituents are maintained for the FTSE 100 Index. Where a greater number of companies qualify to be inserted in the FTSE 100 Index than those qualifying to be deleted, the lowest ranking constituents presently included in the FTSE 100 Index will be deleted to ensure that an equal number of companies are inserted and deleted at the periodic review. Likewise, where a greater number of companies qualify to be deleted than those qualifying to be inserted, the securities of the highest ranking companies which are presently not included in the FTSE 100 Index will be inserted to match the number of companies being deleted at the periodic review.

For the purposes of computing the FTSE 100 Index, the number of shares in issue for each constituent security is expressed to the nearest share and, to prevent a large number of insignificant weighting changes, the number of shares in issue for each constituent security is amended only when the total shares in issue held within the index system changes by more than 1% on a cumulative basis. Changes are made quarterly after the close of business on the third Friday of March, June, September and December. However, if a corporate action is applied to a FTSE 100 Index constituent which involves a change in the number of shares in issue, the change in shares will be applied simultaneously with the corporate action, and if accumulated changes in the number of shares in issue add up to 10% or more, or when an accumulated share change represents U.S.$2 billion of a company’s total market capitalization, such changes are implemented between quarters. A minimum of four days’ notice is given to users of the FTSE 100 Index. WM/Reuters Spot Rates are used to convert the market capitalization into U.S. dollars. The U.S.$2 billion threshold may be adjusted annually in December by the FTSE Policy Group, and such adjustment would be applied for the first time at the next review in March of the following year.

The FTSE 100 Index is calculated in real-time and published every 15 seconds during the FTSE 100 Index opening hours between 08.00 a.m and 04.30 p.m GMT using real time prices. The FTSE 100 Index Return is calculated based on the closing levels of the FTSE 100 Index on the Exchange, as reported by Bloomberg L.P. under ticker symbol “UKX.”

The FTSE 100 Index is calculated using the free float index calculation methodology of FTSE. The FTSE 100 Index is calculated using the following formula:

i	=		1,2,3.............., n
n	=		The number of securities in the FTSE 100 Index.
P	=	Price	The latest trade price of the component security (or the price at the close of the FTSE 100 Index on the previous day)

e	=	Exchange Rate	The exchange rate required to convert the security’s home currency into the index’s base currency.
s	=	Shares in Issue	The number of shares in issue used by FTSE for the security, as defined in the Ground Rules.
f	=	Free Float Factor	The factor to be applied to each secuity to allow amendments to its weighting, expressed as a number between 0 and 1, where 1 represents a 100% free float. The free float factor for each security is published by FTSE.
d	=	Divisor	A figure that represents the total issued share capital of the FTSE 100 Index at the base date. The divisor can be adjusted to allow changes in the issued share capital of individual securities to be made without distorting the FTSE 100 Index.

Under this methodology, FTSE International Limited (“FTSE”, also the “FTSE 100 Index Sponsor”) excludes from free floating shares trade investments in a FTSE 100 Index constituent company by another FTSE 100 Index constituent company, significant long-term holdings by founders, directors and/or their families, employee share schemes (if restricted), government holdings, and portfolio investments subject to lock-in clauses (for the duration of the clause). Free float restrictions are calculated using available published information. The initial weighting of a FTSE 100 Index Constituent Stock is applied in bands, as follows:

Free float less than or equal to 15%	Ineligible for inclusion in the FTSE 100 Index, unless free float is also greater than 5% and the full capitalization is greater than U.S.$5 billion, in which case actual free float is used.
Free float greater than 15% but less than or equal to 20%	20%
Free float greater than 20% but less than or equal to 30%	30%
Free float greater than 30% but less than or equal to 40%	40%
Free float greater than 40% but less than or equal to 50%	50%
Free float greater than 50% but less than or equal to 75%	75%
Free float greater than 75%	100%

These bands are narrow at the lower end, to ensure that there is sufficient sensitivity in order to maintain accurate representation, and broader at the higher end, in order to ensure that the weightings of larger companies do not fluctuate absent a significant corporate event. Following the application of an initial free float restriction, a constituent’s free float will only be changed if its actual free float moves to more than 5 percentage points above the minimum or 5 percentage points below the maximum of an adjacent new band. This 5 percentage points threshold does not apply if the change is greater than one band; therefore a movement of 10 percentage points for the bands between 20% and 50% and 25 percentage points for the bands between 50% and 100% will not be subject to the 5 percentage point threshold. The 15% limit will also not be subject to the 5 percentage point threshold.

The FTSE^TM 100 Index

Stocks must be sufficiently liquid to be traded. The following criteria will be used to ensure that illiquid securities are excluded:

Price.  The EMEA Committee must be satisfied that an accurate and reliable price for the purposes of determining the market value of a company exists. The EMEA Committee may exclude a security from the FTSE 100 Index should it consider that an 'accurate and reliable' price is not available.

Liquidity.  Each security will be tested for liquidity by calculation of its median daily trading per month. The median trade is calculated by ranking each daily trade total and selecting the middle ranking day. Daily totals with zero trades are included in the ranking, therefore a security that fails to trade for more than half of the days in a month will have a zero median trade.

New issues.  New issues, must have a minimum trading record of at least 20 trading days prior to the date of the review and turnover of a minimum of 0.5% of their shares in issue, after the application of any free float restrictions, per month in each month.

FTSE/Xinhua China 25 Index^TM

The FTSE/Xinhua China 25 Index^TM (the “China 25 Index”) is designed to represent the performance of the mainland Chinese market that is available to international investors. The China 25 Index is a real-time index consisting of 25 of the largest and most liquid Chinese stocks (each, a “China 25 Index Constituent Stock”) listed and trading on the Stock Exchange of Hong Kong Ltd. (HKSE). The shares comprised by the China 25 Index are classified as “H Shares” or “Red Chip Shares.” H Shares are securities of companies incorporated in the People's Republic of China and nominated by the Chinese government for listing and trading on the HKSE. H Shares are quoted and traded in Hong Kong dollars (HKD). Like other securities trading on the HKSE, there are no restrictions on who can trade H Shares. Red Chip Shares are securities of companies incorporated outside the People’s Repubic of China that trade on the HKSE. These securities are quoted and traded in HKD. Red Chip Shares are shares of companies that are substantially owned directly or indirectly by the Chinese Government and have a majority of their business interests in mainland China. Individual constituent weights are capped at 10% to avoid over concentration in any one stock. The weights of all lower ranking constituents are increased correspondingly. The China 25 Index has a base value of 5000, which was the value of the index on March 16, 2001, the base date. The China 25 Index is published every 15 seconds between 10:00 a.m. and 4:15 p.m., Hong Kong time, using last trade prices. End of day data is as of 4:30 p.m. The China 25 Index is not calculated on Hong Kong public holidays.

The China 25 Index is calculated using the free float index calculation methodology of FTSE International Limited. The index is calculated using the following formula:

n = 1,2,3............., n

n	=	Number	The number of securities in the China 25 Index.
p	=	Price	The latest trade price of the component security (or the price at the close of the China 25 Index on the previous day)
e	=	Exchange Rate	The exchange rate required to convert the security’s home currency into the index’s base currency.
s	=	Shares in Issue	The number of shares in issue used by FTSE Xinhua for the security, as defined in the Ground Rules.
f	=	Free Float Factor	The factor to be applied to each security to allow amendments to its weighting, expressed as a number between 0 and 1, where 1 represents a 100% free float. The free float factor for each security is published by FTSE Xinhua.
c	=	Capping Factor	The factor applied to each security to allow its weight within the China 25 Index to be capped, expressed as a number between 0 and 1 where 1 represents 100%, i.e. no cap. The capping factor is published by FTSE Xinhua.
d	=	Divisor	A figure that represents the total issued share capital of the China 25 Index at the base date. The divisor can be adjusted to allow changes in the issued share capital of individual securities to be made without distorting the China 25 Index.

IS-44

FTSE/Xinhua China 25 Index^TM

The China 25 Index uses actual trade prices for securities with local stock exchange quotations and Reuters real-time spot currency rates for its calculations.

Under this methodology, the FTSE Xinhua Index Committee excludes from free floating shares trade investments in a China 25 Index constituent company by another China 25 Index constituent company, significant long-term holdings by founders, directors and/or their families, employee share schemes (if restricted), government holdings, foreign ownership limits, and portfolio investments subject to lock-in clauses (for the duration of the clause). Free float restrictions are calculated using available published information. The initial weighting of a China 25 Index Constituent Stock is applied in bands, as follows:

Free float less than or equal to 15%	Ineligible for inclusion in the China 25 Index, unless free float is also greater than 5% and the full capitalization is greater than U.S.$2.5 billion (or local currency equivalent), in which case actual free float is used.
Free float greater than 15% but less than or equal to 20%	20%
Free float greater than 20% but less than or equal to 30%	30%
Free float greater than 30% but less than or equal to 40%	40%
Free float greater than 40% but less than or equal to 50%	50%
Free float greater than 50% but less than or equal to 75%	75%
Free float greater than 75%	100%

These bands are narrow at the lower end, to ensure that there is sufficient sensitivity in order to maintain accurate representation, and broader at the higher end, in order to ensure that the weightings of larger companies do not fluctuate absent a significant corporate event. Following the application of an initial free float restriction, a China 25 Index Constituent Stock's free float will only be changed if its actual free float is more than 5 percentage points above the minimum or 5 percentage points below the maximum of an adjacent band. This 5 percentage points threshold does not apply if the initial free float is less than 15%. Foreign ownership limits, if any, are applied after calculating the actual free float restriction, but before applying the bands shown above. If the foreign ownership limit is more restrictive than the free float restriction, the precise foreign ownership limit is applied. If the foreign ownership limit is less restrictive or equal to the free float restriction, the free float restriction is applied, subject to the bands shown above.

As of December 2005, the China 25 Index adopted a new classification system, the Industry Classification Benchmark (“ICB”). The ICB replaced the FTSE Global Classification System formerly used by the China 25 Index and covers over 65,000 securities worldwide. The new structure is a merger of FTSE Group and Dow Jones Indexes' industry classification systems, creating a single, definitive structure for the market.

The China 25 Index is periodically reviewed for changes in free float. These reviews coincide with the quarterly reviews undertaken of the China 25 Index by the FTSE Xinhua Index Committee. Implementation of any changes takes place after the close of the index calculation on the third Friday in January, April, July and October. A stock's free float is also reviewed and adjusted if necessary following certain corporate events. If the corporate event includes a corporate action which affects the China 25

IS-45

FTSE/Xinhua China 25 Index^TM

Index, any change in free float is implemented at the same time as the corporate action. If there is no corporate action, the change in free float is applied as soon as practicable after the corporate event.

A company will be inserted into the China 25 Index at the periodic review if it rises to 15th position or above when the eligible companies are ranked by full market capitalization (before the application of any investability weightings). In determining the full market capitalisation of a company for this purpose, all share classes are included, while only the eligible share classes are included in the index weighting.

A company in the China 25 Index will be deleted at the periodic review if it falls to 36th position or below when the eligible companies are ranked by full market value (before the application of any investability weightings). In determining the full market capitalization of a company for this purpose, all share classes are included, while only the eligible share classes are included in the index weighting.

Stocks must be sufficiently liquid to be traded. The following criteria, among others, are used to ensure that illiquid stocks are excluded:

Ø Price. The FTSE Xinhua Index Committee must be satisfied that an accurate and reliable price exists for the purposes of determining the market value of a company. The FTSE Xinhua Index Committee may exclude a stock from the China 25 Index if it considers that an “accurate and reliable” price is not available. The China 25 Index uses the last trade prices from the HKSE, when available.

Ø Liquidity. Stocks in the China 25 Index will be reviewed annually for liquidity. Stocks that do not turn over at least 2% of their shares in issue, after the application of any free float restrictions, per month for ten of the twelve months prior to the quarterly review by the FTSE Xinhua Index Committee will not be eligible for inclusion in the China 25 Index. An existing constituent failing to trade at least 2.0% of its shares in issue, after the application of any free float restrictions, per month for more than four of the twelve months prior to the quarterly review will be removed after close of the index calculation on the next trading day following the third Friday in January, April, July and October. Any period when a share is suspended will be excluded from the calculation.

Ø New issues. New issues must have a minimum trading record of at least 20 trading days prior to the date of the review and turnover of a minimum of 2% of their shares in issue, after the application of any free float restrictions, per month each month, except in certain circumstances.

For the purposes of computing the China 25 Index and to prevent a large number of insignificant weighting changes, the number of shares in issue for each constituent security is amended only when the total shares in issue held within the index system changes by more than 1 on a cumulative basis. If a corporate action is applied to a constituent of the index which involves a change in the number of shares in issue, the change in shares will be applied simultaneously with the corporate action. Changes of shares in issue not arising from corporate actions, amounting to less than 10 of the number of shares in issue but more than 1 will be made quarterly after the close of business on the third Friday of March, June, September and December. If accumulated changes in the number of shares in issue add up to 10 or more, they are implemented between quarters. A minimum of four days’ notice will be given to users of the index.

The China 25 Index, like other indices of the China 25 Index Sponsor, is governed by an independent advisory committee (the “FTSE Xinhua Index Committee”) that ensures that the index is operated in accordance with its published ground rules, and that the rules remain relevant to the China 25 Index.

The Stock Exchange of Hong Kong Ltd.

Trading on the HKSE is fully electronic through an Automatic Order Matching and Execution System, which was introduced in November 1983. The system is an electronic order book in which orders are matched and executed instantaneously if there are matching orders in the book, and on the basis of time/price priority. Online real-time order entry and execution have eliminated the previous limitations of telephone-based trading. Trading takes place through trading terminals on the trading floor. There are no market-makers on the HKSE, but exchange dealers may act as dual capacity broker-dealers. Trading is undertaken from 10:00 a.m. to 4:00 p.m. (Hong Kong time) every Hong Kong day except Saturdays, Sundays and other days on which the HKSE is closed. Hong Kong time is 12 hours ahead of Eastern Daylight Savings Time and 13 hours ahead of Eastern Standard Time. Settlement of trade is required within 48 hours and is conducted by electronic book-entry delivery through the Central Clearing and Settlement System.

Due to the time differences between New York City and Hong Kong, on any normal trading day, trading on the HKSE currently will cease at 3:00 a.m. or 4:00 a.m., New York City time. Therefore, the closing level of the China 25 Index will generally be available in the United States by the opening of business on that business day.

The HKSE has adopted certain measures intended to prevent any extreme short-term price fluctuations resulting from order imbalances or market volatility. Where the HKSE considers it necessary for the protection of the investor or the maintenance of an orderly market, it may at any time suspend dealings in any securities or cancel the listing of any securities in such circumstances and subject to such conditions as it thinks fit, whether requested by the listed issuer or not. The HKSE may also do so where: (1) an issuer fails, in a manner which the HKSE considers material, to comply with the HKSE Listing Rules or its Listing Agreements; (2) the HKSE considers there are insufficient securities in the hands of the public; (3) the HKSE considers that the listed issuer does not have a sufficient level of operations or sufficient assets to warrant the continued listing of the issuer's securities; or (4) the HKSE considers that the issuer or its business is no longer suitable for listing. Investors should also be aware that the HKSE may suspend the trading of individual stocks in certain limited and extraordinary circumstances, until certain price-sensitive information has been disclosed to the public. Trading will not be resumed until aformal announcement has been made. Trading of a company's shares may also be suspended if there is unusual trading activity in such shares.

An issuer may apply for suspension of its own accord. A suspension request will normally only be acceded to in the following circumstances: (1) where, for a reason acceptable to the HKSE, price-sensitive information cannot at that time be disclosed; (2) where the issuer is subject to an offer, but only where terms have been agreed in principle and require discussion with, and agreement by, one or more major shareholders (suspensions will only normally be appropriate where no previous announcement has been made); (3) to maintain an orderly market; (4) where there is an occurrence of certain levels of notifiable transactions, such as substantial changes in the nature, control or structure of the issuer, where publication of full details is necessary to permit a realistic valuation to be made of the securities concerned, or the approval of shareholders is required; (5) where the issuer is no longer suitable for listing, or becomes a “cash” company; or (6) for issuers going into receivership or liquidation. As a result

of the foregoing, variations in the China 25 Index may be limited by suspension of trading of individual stocks which comprise the China 25 Index which may, in turn, adversely affect the value of the Securities.

Hang Seng China Enterprises Index

Hang Seng China Enterprises Index Composition and Maintenance

The Hang Seng China Enterprises Index the (“HSCE Index”) is compiled, published and managed by HSI Services Limited (“HSI”), a wholly-owned subsidiary of the Hang Seng Bank. The HSCE Index is a free float-adjusted market capitalization weighted index. Launched on August 8, 1994, the HSCE Index is comprised of H-shares, which are Hong Kong listed shares, of Chinese enterprises (“H-share companies”). The HSCE Index had a base value of 1,000 at launch, but was rebased as of January 3, 2000 with a value of 2,000 to align with the Hang Seng Composite Index Series, which launched on October 3, 2001. The HSCE Index is reviewed semi-annually, at the same time as the Hang Seng Composite Index (the “HSCI”), and the HSCE Index is comprised of only those H-share companies that are included in the HSCI. The H-share companies that join or leave the HSCI are automatically included in or excluded from the HSCE Index. As of January 5, 2009, the HSCE Index consisted of forty-three (43) companies.

To be included in the HSCI, and, thus, be eligible for inclusion in the HSCE Index, a component stock must have a primary listing on the Main Board of the Stock Exchange of Hong Kong (the “SEHK”). Ineligible from the HSCI are those companies with a secondary listing on the Main Board of the SEHK, stocks listed on the Growth Enterprises Market, and preference shares, debt securities or other derivatives.

A component stock is selected or removed from the HSCI semi-annually based on the following selection criteria and process:

Ø Constituent stocks must not have more than twenty (20) trading days without turnover in the past twelve (12) months, excluding the days when the stock is suspended from trading (“Turnover Screening”); and

Ø After the Turnover Screening, the top 200 stocks in terms of average market capitalization in the past twelve (12) months are selected as constituents. Stocks with less than one year listing history are counted on a pro-rata basis.

HSCI, which aims to cover 90% of the market capitalization of stocks listed on the Main Board of the SEHK, consists of 200 constituents.

Calculation Methodology

The HSCE Index is calculated using the following formula:

Current Index =                             × Yesterday’s Closing Index

Where P _t is the current price at day t, P _t-1 is the closing price at day (t-1), IS is the issued H-shares, FAF is the free float adjusted factor, and CF is the Cap Factor. The FAF, which is adjusted every six months, represents the proportion of shares that are free floated as a percentage of the issued H-shares. The FAF is between 0 and 1 and is rounded up to the nearest multiple of 5% for index calculation. The CF is also adjusted every six months and is calculated so that no constituent stock has a weighting that exceeds 15%.

The following shareholdings are viewed as strategic in nature and are excluded from the HSCE Index calculation:

Ø Strategic holdings: shares held by strategic shareholder(s) who individually or collectively control more than 30% of the shareholdings;

Ø Directors' holdings: shares held by director(s) who individually control more than 5% of the shareholdings;

IS-49

Hang Seng China Enterprises Index

Ø Cross-holdings: shares held by a Hong Kong-listed company which controls more than 5% of the shareholdings as investments; and

Ø Lock-up shares: shares held by shareholder(s) who individually or collectively represent more than 5% of the shareholdings in the company and have a publicly disclosed lock-up arrangement.

We have derived all information contained in this index description regarding the HSCE Index, including, without limitation, its composition, method of calculation and changes in its components, from publicly available information. Such information reflects the policies of HSI, and is subject to change at the discretion of HSI. We make no representation or warranty as to the accuracy or completeness of such information. HSI is under no obligation to continue to publish, and may discontinue or suspend the publication of, the Hang Seng China Enterprises Index at any time. We do not assume any responsibility for the accuracy or computeness of such information. Historical performance of the HSCE Index is not an indication of future performance. Future performance of the HSCE Index may differ significantly from historical performance, either positively or negatively.

KOSPI 200 Index

The Korea Composite Stock Price 200 Index (the “KOSPI 200 Index”), which is the underlying index for stock index futures and options, is composed of 200 Korean stocks, which make up 93% of the total market value of the Korea Exchange - Stock Market Division (the “KRX — Stock Market”). The constituent stocks are selected on a basis of the market value of the individual stocks, liquidity and their relative positions in the industry groups to which they belong. The KOSPI 200 Index has been calculated and published since June 15, 1994. The base date for the index is January 3, 1990 and the base index is 100.

The Korea KRX - Stock Market Exchange

The KRX - Stock Market's predecessor, the Daehan Stock Exchange, was established in 1956. The KRX - Stock Market is a typical order-driven market, where buy and sell orders compete for best prices. The KRX - Stock Market seeks to maintain a fair and orderly market for trading and regulates and supervises its member firms.

Throughout the trading hours, orders are matched at a price satisfactory to both buy and sell sides, according to price and time priorities. The opening and closing prices, however, are determined by call auctions: at the market opening and closing, orders received for a certain period of time are pooled and matched at the price at which the most number of shares can be executed. The KRX - Stock Market uses electronic trading procedures, from order placement to trade confirmation. The KRX - Stock Market is open from 9:00 a.m. to 3:00 p.m., Korean time, during weekdays. Investors can submit their orders from 8:00 a.m., one hour before the market opening. Orders delivered to the market during the period from 8:00 a.m. to 9:00 a.m. are queued in the order book and matched by call auction method at 9:00 a.m. to determine opening prices. After opening prices are determined, the trades are conducted by continuous auctions until 2:50 p.m. (10 minutes before the market closing). Besides the regular session, the KRX - Stock Market conducts pre-hours and after-hours sessions for block trading and basket trading.

The KRX - Stock Market introduced the random end system to prevent the price distortion caused by deceptive quotations and to enhance the market transparency and identification of fair market prices. The random end system is a system that delays the determination of the opening or closing price when the opening or closing price deviates substantially from the expected price published immediately before the single price auction. The random end system is also applied to the off-hours single price auction. In cases where the highest or lowest indicative price of a stock set during the last 5 minutes before the closing time of the opening (or closing) call session, 8:55 – 9:00 a.m. (or 2:55 – 3:00 p.m.), deviates from the provisional opening (or closing) price by five percent or more, the KRX - Stock Market delays the determination of the opening (or closing) price of the stock up to five minutes and the price is determined randomly within that five minutes. The official opening (or closing) price of such stock is determined at a randomly chosen time within five minutes after the regular opening (or closing) time. The KRX - Stock Market makes public the indicative prices during the opening (or closing) call trading sessions. Pooling together all bids and offers placed during the order receiving hours for the opening (or closing) session, 8:10 – 9:00 a.m. (or 2:50 – 3:00 p.m.), the indicative opening (or closing) prices of all stocks are released to the public on a real-time basis. The KRX - Stock Market tightened the condition for applying the random end system on October 30, 2006. That is, the random end system is not applied unless the provisional opening (closing) price rises or falls more than 1% from the most recent market price.

The KRX - Stock Market sets a limit on the range that the price of individual stocks can change during a day. In addition, when the price and/or trading activities of a stock are expected to show an abnormal movement in response to an unidentified rumor or news, or when an abnormal movement is observed in the market, the KRX - Stock Market may halt the trading of the stock. In such cases, the KRX - Stock Market requests the company concerned to make a disclosure regarding the matter. Once the company

IS-52

KOSPI 200 Index

makes an official announcement regarding the matter, trading can resume within an hour; however, if the KRX - Stock Market deems that the situation was not fully resolved by the disclosure, trading resumption may be delayed.

The KRX - Stock Market introduced circuit breakers in December 1998. The trading in the equity markets is halted for 20 minutes when the KOSPI 200 Index falls by 10 percent or more from the previous day's closing and the situation lasts for one minute or longer. The trading resumes 20 minutes after the circuit breakers take effect. The first price shall be formed as a single price for 10 minutes from the resumption and then a periodic call auction method shall be applied.

As a result of the foregoing, variations in the KOSPI 200 Index may be limited by suspension of trading of the KOSPI 200 Index constituent stocks, individually or in the aggregate, which may in turn adversely affect the value of the Securities.

MSCI Indices

We may offer a Security linked to one or more indices that are part of the “MSCI Global Investable Market Indices” sponsored by MSCI Barra (“MSCI”), including the MSCI-EAFE^® Index (Europe, Asia, Australia and the Far East, the “MSCI-EAFE Index”), and the MSCI Emerging Markets Index^SM (the “MSCI-EM index” and, together with the MSCI-EAFE Index, the “MSCI Indices”).

We have derived all information regarding the MSCI Indices contained in this Index supplement, including, without limitation, the make-up, method of calculation and changes in the components of each such MSCI Index, from publicly available information. Such information reflects the policies of, and is subject to change by MSCI. We do not assume any responsibility for the accuracy or completeness of such information. MSCI has no obligation to continue to publish any such index, and may discontinue publication of the any MSCI Index. Historical performance of the MSCI Indices is not an indication of future performance. Future performance of the MSCI Indices may differ significantly from historical performance, either positively or negatively.

Each MSCI Index is constructed and maintained in the manner described below.

MSCI-EAFE^® Index

The MSCI-EAFE Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance in Europe, Asia, Australia and the Far East, excluding the United States and Canada.

MSCI^® Emerging Markets Index^SM

We have derived all information regarding the MSCI-EM Index contained in this index supplement, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. Such information reflects the policies of, and is subject to change by MSCI. We do not assume any responsibility for the accuracy or completeness of such information. MSCI has no obligation to continue to publish the MSCI-EM Index, and may discontinue publication of the MSCI-EM Index.

The MSCI-EM Index is a free float-adjusted market capitalization index designed to measure equity market performance in the global emerging markets.

Constructing the MSCI Global Investable Market Indices

MSCI undertakes an index construction process which involves:

Ø Defining the Equity Universe.

Ø Determining the market investable Equity Universes.

Ø Defining market capitalization size segments for each market.

Ø Applying index continuity rules for the Standard Indices.

Ø Creating style indices within each size segment.

Ø Classifying the universe of securities under the Global Industry Classification Standard.

Ø Creating size segment indices.

Defining the Equity Universe

The Equity Universe is defined by identifying eligible equity securities and classifying these eligible equity securities into the appropriate country.

IS-55

MSCI Indices

The Equity Universe initially looks at securities listed in any of the countries in the MSCI Global Index Series. All listed equity securities, or listed securities that exhibit characteristics of equity securities, except mutual funds, ETFs, equity derivatives, limited partnerships, and most investment trusts are eligible for inclusion in the Equity Universe. Real Estate Investment Trusts (REITs) in some countries and certain income trusts in Canada are also eligible for inclusion. Each company and its securities (i.e., share classes) is classified in one and only one country, which allows for a distinctive sorting of each company by its respective country.

Determining the Market Investable Equity Universes

A Market Investable Equity Universe for a market is derived by applying investability screens to individual companies and securities in the Equity Universe that are classified in that market. Generally, a market is equivalent to a single country. The Global Investable Equity Universe is the aggregation of all Market Investable Equity Universes.

Some of the investability requirements referred to above are applied at the individual security level and some at the overall company level, represented by the aggregation of individual securities of the company. As such, the inclusion or exclusion of one security does not imply the automatic inclusion or exclusion of other securities of the same company.

Defining Market Capitalization Size Segments for Each Market

Once a Market Investable Equity Universe is defined, it is segmented into the following size-based indices:

Ø Investable Market Index (Large + Mid + Small)

Ø Standard Index (Large + Mid)

Ø Large Cap Index

Ø Mid Cap Index

Ø Small Cap Index

The Investable Market Index, the Standard Index and the Large Cap Index are created first, while the Mid Cap Index is derived as the difference between the Standard Index and the Large Cap Index and the Small Cap Index is derived as the difference between the Investable Market Index and the Standard Index.

In order to create size segments that can be meaningfully aggregated into composites, the individual Market Size Segments are balanced according to the following two objectives:

Ø Achieving Global Size Integrity by ensuring that, within a given size segment of a composite index, only companies of comparable and relevant sizes are included across all markets. This can be measured by looking at a size segment cutoff relative to a free float-adjusted market capitalization coverage target based on the Global Investable Equity Universe.

Ø Achieving Consistent Market Coverage by ensuring that each market’s size segment is represented in its proportional weight in the composite universe. This can be measured by looking at a size segment cutoff relative to a consistent and comparable target size segment coverage within each market.

It is not possible to achieve both of these objectives consistently and simultaneously across all markets. Therefore, to balance these objectives, the methodology sets a minimum size cutoff for each size segment in each market using:

Ø A size range for all markets derived from a free float-adjusted target market capitalization of the Global Investable Equity Universe, together with

IS-56

MSCI Indices

Ø A target free float-adjusted coverage range set within each individual Market Investable Equity Universe. The intersection of these ranges specifies a Size and Coverage Target Area. This is done for each of the three size segment indices, namely the Investable Market Index, the Standard Index, and the Large Cap Indices.

Applying Index Continuity Rules for the Standard Indices

In order to achieve index continuity, as well as provide some basic level of diversification within a market index, notwithstanding the effect of other index construction rules applied by MSCI, a minimum number of five constituents will be maintained for a Developed Market Standard Index and a minimum number of three constituents will be maintained for an Emerging Market Standard Index. The application of this requirement involves the following steps.

Ø If after the application of the index construction methodology, a Standard Index contains fewer than five securities in a Developed Market or three securities in an Emerging Market, then the largest securities by free float-adjusted market capitalization are added to the Standard Index in order to reach five constituents in that Developed Market or three in that Emerging Market.

Ø At subsequent Index Reviews, if the free float-adjusted market capitalization of a non-index constituent is at least 1.50 times the free float-adjusted market capitalization of the smallest existing constituent after rebalancing, the larger free float-adjusted market capitalization security replaces the smaller one.

When the Index Continuity Rule is in effect, the Market Size-Segment Cutoff is set at 0.5 times the Global Minimum Size Reference for the Standard Index rather than the full market capitalization of the smallest company in that market’s Standard Index.

Creating Style Indices Within Each Size Segment

All securities in the investable Equity Universe are classified into Value or Growth segments using the MSCI Global Value and Growth methodology.

Classifying the Universe of Securities Under the Global Industry Classification Standard

All securities in the Global Investable Equity Universe are assigned to the industry that best describes their business activities. To this end, MSCI has designed, in conjunction with Standard & Poor’s, a division of The McGraw-Hill Companies, Inc., the Global Industry Classification Standard (“GICS”).

The GICS currently consists of 10 sectors, 24 industry groups, 68 industries, and 154 sub-industries. Under the GICS, each company is assigned uniquely to one sub-industry according to its principal business activity. Therefore, a company can only belong to one industry grouping at each of the four levels of the GICS.

The GICS guidelines used to determine the appropriate industry classification are as follows:

Ø A security is classified in a sub-industry according to the business activities that generate approximately 60% or more of the company’s revenues.

Ø A company engaged in two or more substantially different business activities, none of which contributes 60% or more of revenues, is classified in the sub-industry that provides the majority of both the company’s revenues and earnings.

Ø Where the above guidelines cannot be applied, or are considered inappropriate, further analysis is conducted, and other factors are analyzed to determine an appropriate classification.

Creating Size Segment Indices

Generally, MSCI will determine the market size-segment cutoffs for each segment and assign companies to the various size segments.

IS-57

MSCI Indices

Maintaining the MSCI Global Investable Market Indices

Index maintenance involves:

Ø Semi-Annual Index Reviews in May and November of the Size Segment and Global Value and Growth Indices which include:

Ø Updating the indices on the basis of a fully refreshed Equity Universe.

Ø Taking buffer rules into consideration for migration of securities across size and style segments.

Ø Updating Foreign Inclusion Factors (“FIFs”) and Number of Shares (“NOS”).

Ø Quarterly Index Reviews in February and August of the Size Segment Indices aimed at:

Ø Including significant new eligible securities (such as IPOs which were not eligible for earlier inclusion) in the index.

Ø Allowing for significant moves of companies within the Size Segment Indices, using wider buffers than in the semi-annual index reviews.

Ø Reflecting the impact of significant market events on FIFs and updating NOS.

Ø Ongoing event-related changes. Changes of this type are generally implemented in the indices as they occur. Significantly large IPOs are included in the indices after the close of the company’s tenth day of trading.

Semi-Annual Index Reviews in May and November

The objective of the semi-annual index reviews is to systematically reassess the various dimensions of the Equity Universe for all markets on a fixed semi-annual timetable. A semi-annual index review involves a comprehensive review of the Size Segment and Global Value and Growth Indices.

During each semi-annual index review, the Equity Universe is updated and the Global Minimum Size Range is recalculated for each size segment. Then, the following index maintenance activities are undertaken for each market:

Ø Updating the Market Investable Equity Universe.

Ø Reassessing the Segment Number of Companies and the Market Size-Segment Cutoffs.

Ø Assigning companies to the size segments taking into account buffer zones.

Ø Assessing conformity with Final Size-Segment Investability Requirements.

Quarterly Index Reviews in February and August

Quarterly index reviews are designed to ensure that the indices continue to be an accurate reflection of the evolving equity marketplace. This is achieved by a timely reflection of significant market driven changes that were not captured in the index at the time of their actual occurrence but are significant enough to be reflected before the next semi-annual index review. Quarterly index reviews may result in additions or deletions due to migration to another Size Segment Index, and changes in FIFs and in NOS. Only additions of significant new investable companies are considered, and only for the Standard Index. The buffer zones used to manage the migration of companies from one segment to another are wider than those used in the semi-annual index reviews. The style classification is reviewed only for companies that are reassigned to a different size segment.

Ongoing Event-Related Changes

Ongoing event-related changes to the indices are the result of mergers, acquisitions, spin-offs, bankruptcies, reorganizations and other similar corporate events. They can also result from capital

IS-58

MSCI Indices

reorganizations in the form of rights issues, bonus issues, public placements and other similar corporate actions that take place on a continuing basis. These changes generally are reflected in the indices at the time of the event.

These events can affect many aspects of an index and its constituents, including inclusion or deletion of companies outside of the Index Reviews, weight changes due to changes in foreign ownership limits, foreign inclusion factors, number of shares, etc., and changes in size, style and/or industry classification.

Announcement Policy

The results of the semi-annual index review are announced at least two weeks in advance of their effective implementation dates as of the close of the last business day of May and November.

The results of the quarterly index review are announced at least two weeks in advance of their effective implementation dates as of the close of the last business day of February and August.

All changes resulting from corporate events are announced prior to their implementation in the MSCI Global Investable Market Indices.

The changes are typically announced at least ten business days prior to the changes becoming effective in the indices as an “expected” announcement, or as an “undetermined” announcement, when the effective dates are not known yet or when aspects of the event are uncertain. MSCI sends “confirmed” announcements at least two business days prior to events becoming effective in the indices, provided that all necessary public information concerning the event is available.

In exceptional cases, events are announced during market hours for same or next day implementation. Announcements made by MSCI during market hours are usually linked to late company disclosure of corporate events or unexpected changes to previously announced corporate events.

In the case of secondary offerings representing more than 5% of a security’s number of shares for existing constituents, these changes will be announced prior to the end of the subscription period when possible and a subsequent announcement confirming the details of the event (including the date of implementation) will be made as soon as the results are available.

Both primary equity offerings and secondary offerings for US securities, representing at least 5% of the security’s number of shares, will be confirmed through an announcement during market hours for next day or shortly after implementation, as the completion of the events cannot be confirmed prior to the notification of the pricing.

Early deletions of constituents due to bankruptcy or other significant cases are announced as soon as practicable prior to their implementation in the MSCI indices.

Early inclusions of large IPOs in the MSCI Standard Index Series are announced no earlier than the first day of trading and no later than before the opening of the third day of trading in the market where the company has its primary listing.

Early inclusions of already listed securities following large secondary offerings of new and/or existing shares are announced no earlier than shortly after the end of the offer period.

Nikkei^® 225 Index

The Nikkei^® 225 Index (the “Nikkei Index”) is a stock index calculated, published and disseminated by Nihon Keizai Shimbun, Inc. (including its affiliates, the “Nikkei Index Sponsor”) that measures the composite price performance of selected Japanese stocks. The Nikkei Index is currently based on 225 underlying stocks trading on the Tokyo Stock Exchange (the “TSE”), and represents a broad cross-section of Japanese industry. All stocks included in the Nikkei Index trade on the TSE in Japanese yen. All 225 Nikkei Index stocks are listed in the First Section of the TSE. Domestic stocks admitted to the TSE are assigned either to the First Section, Second Section or Mothers Section. Stocks listed in the First Section are among the most actively traded stocks on the TSE. At the end of each business year, the TSE examines each First Section stock to determine whether it continues to meet the criteria for inclusion in the First Section and each Second Section stock to determine whether it may qualify for inclusion in the First Section. Futures and options contracts on the Nikkei Index are traded on the Singapore Exchange Ltd., the Osaka Securities Exchange Co., Ltd. and the Chicago Mercantile
Exchange Inc.

The Nikkei Index is a modified, price-weighted index. Each stock's weight in the Nikkei Index is based on its price per share rather than the total market capitalization of the issuer. The Nikkei Index Sponsor calculates the Nikkei Index by multiplying the per-share price of each stock in the Nikkei Index by the corresponding weighting factor for such stock, calculating the sum of all these products and dividing that sum by a divisor. The weighting factor for each stock in the Nikkei Index is computed by dividing 50 Japanese yen by the par value of that stock, so that the share price of each such stock when multiplied by its weighting factor corresponds to a share price based on a uniform par value of 50 Japanese yen. Each weighting factor represents the number of shares of the related Nikkei Index stock that are included in one trading unit of the Nikkei Index. The stock prices used in the calculation of the Nikkei Index are those reported by a primary market for the stocks in the Nikkei Index, which is currently the TSE. The level of the Nikkei Index is calculated once per minute during TSE trading hours.

In order to maintain continuity in the level of the Nikkei Index in the event of certain changes affecting the stocks included in the Nikkei Index, such as the addition or deletion of stocks, substitution of stocks, stock dividends, stock splits or distributions of assets to stockholders, the divisor used in calculating the Nikkei Index is adjusted in a manner designed to prevent any change or discontinuity in the level of the Nikkei Index. The divisor remains at the new value until a further adjustment is necessary as the result of another change. As a result of each change affecting any stock in the Nikkei Index, the divisor is adjusted in such a way that the sum of all share prices immediately after the change multiplied by the applicable weighting factor and divided by the new divisor, the level of the Nikkei Index immediately after the change, will equal the level of the Nikkei Index immediately prior to the change.

Stocks included in the Nikkei Index may be deleted or added by the Nikkei Index Sponsor. However, to maintain continuity in the Nikkei Index, the policy of the Nikkei Index Sponsor is generally not to alter the composition of the Nikkei Index stocks except when a stock is deleted in accordance with the following criteria.

Any stock in the Nikkei Index becoming ineligible for listing in the First Section of the TSE due to any of the following reasons will be deleted from the Nikkei Index: bankruptcy of the issuer; merger of the issuer into, or acquisition of the issuer by, another company; delisting of the stock because of excess debt of the issuer or because of any other reason; transfer of the stock to the “Kanri Post” (Post for stocks under supervision); transfer of the stock to the “Seiri Post” (the Liquidation Post); or transfer of the stock to the Second Section of the TSE. In addition, any stock in the Nikkei Index with relatively low liquidity, based on trading volume and price fluctuation over the past five years, may be deleted by the Nikkei Index Sponsor. Upon deletion of a stock from the Nikkei Index, the Nikkei Index Sponsor will select, in

IS-61

Nikkei^® 225 Index

accordance with certain criteria established by it, a replacement for the deleted stock. Until such replacement, the Nikkei Index will be calculated with the remaining stocks included in the Nikkei Index less the deleted stocks.

A list of the issuers of the stocks included in the Nikkei Index is available from the NKS Economic Electronic Databank System and the Nikkei Index Sponsor directly. The Nikkei Index Sponsor may delete, add or substitute any stock underlying the Nikkei Index.

The Tokyo Stock Exchange

The TSE is one of the world's largest securities exchanges in terms of market capitalization. Due to time zone differences, on any normal trading day, the TSE will close before the opening of business in New York City on the same calendar day. Therefore, the closing level of the Nikkei Index on any particular business day will generally be available in the United States by the opening of business on that business day.

The TSE has adopted certain measures, including daily price floors and ceilings on individual stocks, intended to prevent any extreme short-term price fluctuations resulting from order imbalances. In general, any stock listed on the TSE cannot be traded at a price lower than the applicable price floor or higher than the applicable price ceiling. These price floors and ceilings are expressed in absolute Japanese yen, rather than percentage limits based on the closing price of the stock on the previous trading day. In addition, when there is a major order imbalance in a listed stock, the TSE posts a “special bid quote” or a “special offer quote” for that stock at a specified higher or lower price level than the stock's last sale price in order to solicit counter-orders and balance supply and demand for the stock. Prospective investors should also be aware that the TSE may suspend the trading of individual stocks in certain limited and extraordinary circumstances, including, for example, unusual trading activity in that stock. As a result, changes in the Nikkei Index may be limited by price limitations, special quotes or by suspension of trading on stocks in the Nikkei Index, and these limitations may, in turn, adversely affect the value of the Securities.

The S&P/ASX 200^® Index

The S&P/ASX 200^® Index (the “S&P/ASX 200 Index”) was introduced in April 2000 and is maintained by the S&P Australian Index Committee (the “ASX Committee”), a team of five representatives from both S&P (as defined below) and the Australian Securities Exchange.

The S&P/ASX 200 Index is composed of the S&P/ASX 100 stocks plus an additional 100 stocks selected by the ASX Committee. The S&P/ASX 200 Index essentially covers large-cap and mid-cap stocks evaluated for liquidity and size.

The S&P/ASX 200 Index weights companies according to the Global Industry Classification Standard (“GICS”), which creates uniform ground rules for replicable, custom-tailored, industry-focused portfolios. It also enables meaningful comparisons of sectors and industries across regions. Sector indices are available for the S&P/ASX 200 Index.

The ASX Committee reviews constituents quarterly to ensure adequate market capitalization and liquidity. Both market capitalization and liquidity are assessed using the previous six months worth of data. Quarterly review changes take effect on the third Friday of December, March, June and September. The weighting of constituents in the S&P/ASX 200 Index is determined by the free float assigned to each stock by the ASX Committee. Each index constituent’s free float is reviewed as part of the March quarterly review.

Only stocks listed on the Australian Stock Exchange (the “ASX”) are considered for inclusion in the S&P/ASX 200 Index. Stocks are assessed based on the average of their previous six-month day-end free float adjusted market capitalization. Only stocks that are actively and regularly traded are considered for inclusion in the S&P/ASX 200 Index. A stock’s liquidity is measured relative to its size peers. A minimum free float threshold of 30% exists for a stock to warrant inclusion in the S&P/ASX 200 Index. Stocks must not necessarily comply strictly with these guidelines in order to maintain confirmed index membership. The ASX Committee seeks to minimize unnecessary charges in index composition. Each stock considered for removal from the S&P/ASX 200 Index is evaluated on a case-by-case basis.

The S&P/ASX 200 Index has a base value of 3000. Calculation for the S&P/ASX 200 Index is based on stock prices taken from the ASX. The official daily index closing values for price and accumulation indices are calculated after the market closes and are based on the last traded price for each constituent.

You may find information about the S&P/ASX 200^® Index on the S&P website at www2.standardandpoors.com.

We have derived all information regarding the S&P/ASX 200 Index contained in this index supplement from publicly available information without independent verification.

Swiss Market Index (SMI)^®

The Swiss Market Index (SMI)^® (the “SMI Index”) was introduced on June 30, 1988 at a baseline value of 1500 points and is maintained by the SIX Swiss Exchange (the “SMI Index Sponsor”). Its composition is examined once a year.

The SMI Index contains approximately 85% of the entire free float market capitalization of the Swiss equity market and is made up of 20 of the largest and most liquid stocks from the SPI (as described below). The SMI Index is primarily available as a non-dividend-corrected index (price index), but is also published under the designation SMIC^® (SMI^® cum dividend) as a performance index. Your Securities will be linked to the SMI Index, not the SMIC^® index.

The basic universe for admission to the SMI Index is the Swiss Performance Index (“SPI”). In order to be admitted and remain in the SPI universe a given security must meet a minimum free float rate of 20%. If a stock falls below this limit and does not reach or exceed it again within three months, it is excluded. Stocks, which are not admitted to the SPI universe on free float grounds, are admitted if the minimum free float rate of 20% has been met continuously over a period of three months.

In order to limit fluctuations in the index basket, the selection list features a tolerance zone which inhibits securities' addition to and exclusion from the SMI Index. All securities in the SPI stock universe are ranked annually based on a combination of market capitalization and the percentage of sales at the market value of each individual security. A security is admitted to the SMI Index if it ranks 18 or better in the annual rankings. A security newly ranked 19 or 20 is admitted only if a security that was already included in the SMI Index meets the exclusion criteria directly (i.e., ranks in position 23 or lower) and no security that either meets the admission criteria directly (i.e., ranks in position 18 or higher) or is rated higher has moved up in its place. A security is excluded from the SMI Index if it ranked 23 or lower in the annual rankings. A security that was already included in the SMI Index which newly ranks 21 or 22 is excluded only if a security that was not already included in the SMI Index meets the admission criteria directly (i.e., ranks in position 18 or higher) and no security that either meets the exclusion criteria directly (position 23 or lower) or is rated lower has been excluded in its place.

The SMI Index Return will be calculated based on the closing levels of the SMI Index, as reported by Bloomberg L.P. under ticker symbol “SMI.” Calculation takes place in real-time: as soon as a new transaction occurs in a security contained in the SMI Index, an updated index level is calculated and displayed.

Structured Product Characterization

To help investors identify appropriate investment products (“structured products”), UBS organizes its structured products, including the Securities, into four categories: Protection Strategies, Optimization Strategies, Performance Strategies and Leverage Strategies. The description below is intended to describe generally the four categories of structured products and the types of protection that may be offered on those products. This description should not be relied upon as a description of any particular structured product.

Ø Protection Strategies are structured to provide investors with a high degree of principal protection at maturity, periodic coupons or a return at maturity with the potential to outperform traditional fixed income instruments. These structured products are designed for investors with low to moderate risk tolerances.

Ø Optimization Strategies are structured to optimize returns or yield within a specified range. These structured products are designed for investors with moderate to high risk tolerances. Optimization Strategies may be structured to provide no principal protection, partial protection or contingent protection.

Ø Performance Strategies are structured to be strategic alternatives to index funds or exchange traded funds or to allow efficient access to new markets. These structured products are designed for investors with moderate to high risk tolerances. Performance Strategies may be structured to provide no principal protection, partial protection or contingent protection.

Ø Leverage Strategies are structured to provide leveraged exposure to the performance of an underlying asset. These structured products are designed for investors with high risk tolerances.

“Partial protection”, if applicable, provides principal protection against a decline in the price or level of the underlying asset down to a specified threshold; investors will lose 1% of principal for every 1% decline in the price or level of the underlying asset below the specified threshold. “Contingent protection”, if applicable, provides principal protection at maturity as long as the price or level of the underlying asset does not trade below a specified threshold; if the price or level of the asset declines below the specified threshold at any time during the term of the notes, all principal protection is lost and the investor will have full downside exposure to the price or level of the underlying asset. In order to benefit from any type of principal protection, investors must hold the security to maturity.

Classification of structured products into categories is not intended to guarantee particular results or performance.
