**Equity Index Underlying Supplement**

(To Prospectus Supplement dated June 4, 2026 and

Prospectus dated June 4, 2026)

**Canadian Imperial Bank of Commerce** 

**Notes Linked to One or More Equity Indices**

Canadian Imperial Bank of Commerce ("**CIBC**") from time to time may offer and sell certain senior unsecured debt obligations (the "**notes**") linked to the performance of an underlying "**Reference Asset**," which will be an index that tracks the performance of equity securities (the "**Index**"). The Reference Asset may also consist of a "**Basket**" of two or more Indices (the "**Basket Components**"). The notes may also be linked to the worst performing of two or more Indices. The applicable free writing prospectus or pricing supplement (the "**pricing supplement**") will specify the Reference Asset to which your notes are linked, as well as specific terms of the notes.

Notwithstanding anything to the contrary set forth in the accompanying prospectus supplement for senior global medium-term notes dated June 4, 2026 (the "**prospectus supplement**") and the accompanying prospectus for senior debt securities dated June 4, 2026 (the "**prospectus**"), this underlying supplement describes additional terms of the notes, certain risks related to the notes and the Reference Asset, and some of the Indices to which the return on the notes may be linked.

You should read the applicable pricing supplement, this underlying supplement and the accompanying prospectus supplement and prospectus carefully before you invest in a particular issuance of the notes. If the terms described in the applicable pricing supplement are different from or inconsistent with those described herein, the terms described in the applicable pricing supplement will govern the applicable notes.

The descriptions of indices in this underlying supplement only apply to selected equity indices to which the notes may be linked. We do not guarantee that we will offer the notes linked to any of the indices described herein. In addition, we may offer the notes linked to one or more equity indices that are not described herein. In such an event, we will describe such additional equity index or indices in the applicable pricing supplement, or in another underlying supplement.

The notes are unsecured obligations of CIBC and are not savings accounts or insured deposits of a bank. The notes are not insured by the U.S. Federal Deposit Insurance Corporation, the Canada Deposit Insurance Corporation, or any other government agency or instrumentality of the United States, Canada or any other jurisdiction.

Potential purchasers of the notes should consider the information in "Risk Factors" beginning on page S-1 of this underlying supplement, page S-1 of the accompanying prospectus supplement and page 1 of the accompanying prospectus. **You may lose some or all of the principal amount of your notes.** Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of CIBC.

Neither the Securities and Exchange Commission (the "**SEC**") nor any state securities commission has approved or disapproved of these notes or determined if this document, the accompanying prospectus supplement or prospectus, or any pricing supplement is truthful or complete. Any representation to the contrary is a criminal offense.

Unless otherwise specified in the applicable pricing supplement, the notes will not be listed on a securities exchange.

In making your investment decision, you should rely only on the information contained or incorporated by reference in the applicable pricing supplement, this underlying supplement, any related underlying supplement and the accompanying prospectus supplement and prospectus. The information in the applicable pricing supplement and any related underlying supplement, including this underlying supplement, may only be accurate as of the dates of each of such documents. Certain capitalized terms used and not defined in this underlying supplement have the meanings ascribed to them in the accompanying prospectus supplement and prospectus.

The notes described in the applicable pricing supplement and this underlying supplement are not appropriate for all investors, and involve important legal and tax consequences and investment risks, which should be discussed with your professional advisers. The applicable pricing supplement, any related underlying supplement including this underlying supplement and the accompanying prospectus supplement and prospectus do not constitute an offer to sell or a solicitation of an offer to buy the notes in any circumstances in which such offer or solicitation is unlawful.

In this underlying supplement, the "Bank," "CIBC," "we," "us" and "our" refer to Canadian Imperial Bank of Commerce, unless the context requires otherwise.

None of CIBC, the agents, or any of our respective affiliates accepts any responsibility for the calculation, maintenance or publication of the Indices described herein or any Successor Indices (as defined herein).

**RISK FACTORS**

Your investment in the notes will involve certain risks, many of which differ from those of a conventional debt security. We urge you to read the section "Risk Factors" beginning on page S-1 of the accompanying prospectus supplement and page 1 of the accompanying prospectus, in any related underlying supplement, and in the applicable pricing supplement in addition to the following risk factors relevant to your notes. Investing in the notes is not equivalent to investing directly in the securities included in an Index. You should understand the risks of investing in the notes and should reach an investment decision only after careful consideration, with your advisers, of the suitability of the notes in light of your particular financial circumstances and the information set forth in this underlying supplement, any related underlying supplement, the applicable pricing supplement, and the accompanying prospectus supplement and prospectus. You should not purchase the notes unless you understand and can bear these investment risks.

***Structure Risks***

**Your investment in the notes may result in a loss.**

Unless otherwise specified in the applicable pricing supplement, you may lose your entire investment in the notes, and there can be no assurance of the receipt of any amount at maturity.

**The payment on the notes will not reflect changes in the value of the Reference Asset at any time other than the relevant Valuation Date.**

Changes in the value of the Reference Asset during the term of notes other than on the relevant Valuation Date (as defined below) will not be reflected in the calculation of the payment on the notes. The payment on the notes will be based on the value of the Reference Asset on the relevant Valuation Date (subject to adjustments as described herein, including those described under "Certain Terms of the Notes—Valuation Dates" below). As a result, even if the value of the Reference Asset has increased at certain times during the term of the notes, the payment on the notes may be significantly less than it would otherwise have been had the payment been linked to the value of the Reference Asset other than on the relevant Valuation Date.

**A payment date, including the maturity date, may be postponed if the relevant Valuation Date is postponed.**

A Valuation Date is subject to postponement for non-Trading Days and Market Disruption Events. If such a postponement occurs with respect to a Valuation Date, then the related payment date will be postponed. See "Certain Terms of the Notes—Valuation Dates" below.

**The notes may not bear interest, and your return on the notes may be less than the return on a conventional debt security of comparable maturity.**

Unless otherwise specified in the applicable pricing supplement, your notes do not bear interest. The return on your notes, which could be negative, may be less than the return you could earn on other investments. Even if your notes bear interest and the return on the notes is positive, your return may be less than the return you would earn if you bought a conventional senior interest bearing debt security of the Bank with the same maturity date. Your investment in the notes may not reflect the full opportunity cost to you when you take into account factors that affect the time value of money, such as inflation.

***Credit Risks***

**Payments on the notes are** **subject to our credit risk** **, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes** **.**

The notes are our senior unsecured debt obligations and are not, either directly or indirectly, an obligation of any third party. As further described in the accompanying prospectus supplement and prospectus, the notes will rank on par with all of our other unsecured and unsubordinated debt obligations, except such obligations as may be preferred by operation of law. Any payment to be made on the notes depends on our ability to pay all amounts as they come due. As a result, our actual and perceived creditworthiness may affect the market value of the notes and, in the event we were to default on our obligations, you may not receive the amounts owed to you under the terms of the notes. If we default on our obligations under the notes, your investment would be at risk and you could lose some or all of your investment. See "Description of Senior Debt Securities—Events of Default" in the accompanying prospectus.

------

**The notes are not insured by any third parties.**

The notes will be solely our obligations. Neither the notes nor your investment in the notes are insured by the U.S. Federal Deposit Insurance Corporation, the Canada Deposit Insurance Corporation, or any other government agency or instrumentality of the United States, Canada or any other jurisdiction.

***Market Valuation Risks*** 

**The Bank's initial estimated value of the notes will be lower than the initial issue price (price to public) of the notes.**

The initial issue price of the notes will exceed the Bank's initial estimated value because costs associated with selling and structuring the notes, as well as hedging the notes, are included in the initial issue price of the notes.

**The Bank's initial estimated value does not represent future values of the notes and may differ from others' estimates.** 

The Bank's initial estimated value of the notes is only an estimate, which will be determined by reference to the Bank's internal pricing models when the terms of the notes are set. This estimated value will be based on market conditions and other relevant factors existing at that time, the Bank's internal funding rate on the pricing date and the Bank's assumptions about market parameters, which can include volatility, dividend rates, interest rates and other factors. Different pricing models and assumptions could provide valuations for the notes that are greater or less than the Bank's initial estimated value. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the market value of the notes could change significantly based on, among other things, changes in market conditions, including the value of the Reference Asset, the Bank's creditworthiness, interest rate movements and other relevant factors, which may impact the price at which the agent or any other party would be willing to buy the notes from you in any secondary market transactions. The Bank's initial estimated value does not represent a minimum price at which the agent or any other party would be willing to buy the notes in any secondary market (if any exists) at any time.

**The Bank's initial estimated value of the notes will not be determined by reference to credit spreads for our conventional fixed-rate debt.** 

The internal funding rate to be used in the determination of the Bank's initial estimated value of the notes generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. If the Bank were to use the interest rate implied by our conventional fixed-rate debt, we would expect the economic terms of the notes to be more favorable to you. Consequently, our use of an internal funding rate for market-linked notes would have an adverse effect on the economic terms of the notes, the initial estimated value of the notes on the pricing date, and any secondary market prices of the notes.

**If the value of the Reference Asset changes, the market value of your notes may not change in the same manner.** 

Your notes may trade quite differently from the performance of the Reference Asset. Changes in the value of the Reference Asset may not result in a comparable change in the market value of your notes. See "—The market value of the notes will be affected by various factors that interrelate in complex ways, and their market value may be less than the principal amount" below.

**The market value of the notes will be affected by various factors that interrelate in complex ways, and their market value may be less than the principal amount.** 

The notes are not designed to be short-term trading instruments. Unless otherwise specified in the applicable pricing supplement, you will have no right to have your notes redeemed at your option prior to maturity. If you wish to liquidate your investment in notes prior to maturity, your only option would be to sell them. At that time, there may be an illiquid market for your notes or no market at all. Even if you were able to sell your notes, the price at which the notes may be sold prior to maturity will depend on a number of factors. Some of these factors include, but are not limited to: (i) actual or anticipated changes in the level of an Index over the term of the notes, (ii) volatility of the level of an Index and the market's perception of future volatility of the level of an Index, (iii) economic and other conditions generally, (iv) changes in interest rates generally, (v) dividend yields on securities included in an Index, (vi) correlation among the Indices if the notes are linked to multiple Indices; (vii) currency exchange rates if the notes are linked to

------

an Index that includes securities quoted in one or more foreign currencies; (viii) any actual or anticipated changes in our credit ratings or credit spreads, and (ix) time remaining to maturity.

***Liquidity Risks***

**The notes will not be listed on any securities exchange and we do not expect a trading market for the notes to develop.**

The notes will not be listed on any securities exchange. Although the agents and/or our or their affiliates may purchase the notes from holders, they are not obligated to do so and are not required to make a market for the notes. There can be no assurance that a secondary market will develop for the notes. Because we do not expect that any market makers will participate in a secondary market for the notes, the price at which you may be able to sell your notes is likely to depend on the price, if any, at which the agents and/or our or their affiliates are willing to buy your notes.

If a secondary market does exist, it may be limited. Accordingly, there may be a limited number of buyers if you decide to sell your notes prior to maturity or early redemption, if applicable. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the notes to maturity or early redemption, if applicable.

***Conflicts of Interest***

**Certain business, trading and hedging activities of us, the agents, and our respective affiliates may create conflicts with your interests and could potentially adversely affect the value of the notes.** 

We, the agents, and our respective affiliates may engage in trading and other business activities related to an Index or any securities included in an Index that are not for your account or on your behalf. We, the agents, and our respective affiliates also may issue or underwrite other financial instruments with returns based upon an Index. These activities may present a conflict of interest between your interest in the notes and the interests that we, the agents, and our respective affiliates may have in our or their proprietary accounts, in facilitating transactions, including block trades, for our or their other customers, and in accounts under our or their management. These trading and other business activities, if they adversely affect the value of the Reference Asset or secondary trading in your notes, could be adverse to your interests as a beneficial owner of the notes.

Moreover, we and our affiliates play a variety of roles in connection with the issuance of the notes, including hedging our obligations under the notes and making the assumptions and inputs used to determine the pricing of the notes and the initial estimated value of the notes when the terms of the notes are set. We expect to hedge our obligations under the notes through the agents, one of our or their affiliates, and/or another unaffiliated counterparty, which may include any dealer from which you purchase the notes. Any of these hedging activities may adversely affect the value of the Reference Asset and therefore the market value of the notes and the amount you will receive, if any, on the notes. In connection with such activities, the economic interests of us, the agents, and our respective affiliates may be adverse to your interests as an investor in the notes. Any of these activities may adversely affect the value of the notes. In addition, because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging activity may result in a profit that is more or less than expected, or it may result in a loss. We, the agents, or one or more of our respective affiliates or any unaffiliated counterparty will retain any profits realized in hedging our obligations under the notes even if investors do not receive a favorable investment return under the terms of the notes or in any secondary market transaction. Any profit in connection with such hedging activities will be in addition to any other compensation that we, the agents, our respective affiliates or any unaffiliated counterparty receive for the sale of the notes, which creates an additional incentive to sell the notes to you. We, the agents, our respective affiliates or any unaffiliated counterparty will have no obligation to take, refrain from taking or cease taking any action with respect to these transactions based on the potential effect on an investor in the notes.

**There are potential conflicts of interest between you and the calculation agent.**

The calculation agent will determine, among other things, the amount of your payment on the notes. Unless otherwise specified in the applicable pricing supplement, we will serve as the calculation agent. We may change the calculation agent after the original issue date without notice to you. The calculation agent will exercise its judgment when performing its functions. For example, the calculation agent will determine whether a Market Disruption Event (as defined below) affecting an Index has occurred, and make a good faith estimate in its sole discretion of the Closing Level (as defined below) for an affected Index if the relevant Valuation Date is postponed to the last possible day. See "Certain Terms of the Notes—Valuation Dates" below. This determination may, in turn, depend on the calculation agent's judgment as to whether the event has materially interfered with our ability or the ability of one of our affiliates to unwind our hedge positions. The calculation agent will be required to carry out its duties in good faith and use its

------

reasonable judgment. However, because we are expected to be the calculation agent, potential conflicts of interest could arise. Neither we nor any of our affiliates will have any obligation to consider your interests as a holder of the notes in taking any action that might affect the value of your notes.

**The calculation agent can postpone the determination of the Closing Level of an Index if a Market Disruption Event occurs.**

If the calculation agent determines that a Market Disruption Event has occurred or is continuing on any scheduled Valuation Date with respect to an Index, the applicable Valuation Date for that Index will be postponed. See "Certain Terms of the Notes—Valuation Dates" below. If the scheduled Final Valuation Date (as defined below) is postponed because a Market Disruption Event occurs or is continuing on that day with respect to an Index, the maturity date for the notes will also be postponed. No interest will accrue as a result of a delayed payment.

***General Risks for an Index***

**You must rely on your own evaluation of the merits of an investment linked to the Reference Asset.**

We, the agents, and our respective affiliates, at the time of any offering of the notes or in the future, may engage in business with any company whose securities are included in an Index, including making loans to, equity investments in, or providing investment banking, asset management, or other services to those companies, their affiliates, and their competitors. In connection with these activities, we, the agents, and our respective affiliates may receive information about those companies that we will not divulge to you or other third parties.

In addition, we, the agents, or our respective affiliates have published, and in the future may publish, research reports on one or more of these companies. This research is modified from time to time without notice and may express opinions or provide recommendations that are inconsistent with your interest as a holder of the notes. Any of these activities may adversely affect the market value of the notes. Any prospective purchaser of the notes should undertake an independent investigation of the Reference Asset as in its judgment is appropriate to make an informed decision regarding an investment in the notes. The selection of an Index as the Reference Asset does not reflect any investment recommendations from us.

**As a holder of the notes, you will not have any ownership interest or rights in any securities included in an Index.**

The notes are our debt securities. They are not equity instruments, shares of stock, or securities of any other issuer. Unless otherwise specified in the applicable pricing supplement, your notes will be paid in cash and you have no right to receive any securities included in an Index. As a holder of the notes, you will not have any ownership interest or rights in any securities included in an Index, such as voting rights or rights to receive dividends or other distributions. As a result, the return on your notes may not reflect the return you would realize if you actually owned any securities included in an Index and received the dividends paid or other distributions made in connection with them, and the return on your notes may be less than a comparable investment directly in those securities.

**We** **, the agents, and** **our respective affiliates cannot control actions by any of the unaffiliated companies whose securities are included in an Index.**

Unless otherwise set forth in the pricing supplement, we, the agents, and our respective affiliates do not control any company whose securities are included in an Index and have not verified any disclosure made by any other company. We, the agents, or our respective affiliates may from time to time own securities of companies included in an Index. However, none of us, the agents, or any of our respective affiliates has the ability to control the actions of any of these companies or has undertaken any independent review of, or made any due diligence inquiry with respect to, any of these companies, unless (and only to the extent that) the securities of us, the agents, or our respective affiliates are represented by that Index. These companies will not be involved in the offering of the notes and will have no obligations with respect to the notes, including any obligation to take our or your interests into consideration for any reason. These companies will not receive any of the proceeds of the offering of the notes and will not be responsible for, and will not have participated in, the determination of the timing of, prices for, or quantities of, the notes to be issued. These companies will not be involved with the administration, marketing or trading of the notes and will have no obligations with respect to the payment to be paid to you on the notes. In addition, none of these companies will have any obligation to consider your interests as a holder of the notes in taking any action that might affect the return on the notes.

------

**An Index Sponsor may adjust the relevant Index in a way that affects its level, and it has no obligation to consider your interests.**

Unless otherwise specified in the applicable pricing supplement, we, the agents, and our respective affiliates are not affiliated with a sponsor of any Index (each, an "**Index Sponsor**"). Consequently, we have no control of the actions of any Index Sponsor. An Index Sponsor can add, delete, or substitute the components included in the relevant Index or make other methodological changes that could change its level. A new security included in an Index may perform significantly better or worse than the replaced security, and the performance will impact the level of the Index. Additionally, an Index Sponsor may alter, discontinue, or suspend calculation or dissemination of an Index. Any of these actions could adversely affect the return on your notes. An Index Sponsor will have no obligation to consider your interests in calculating or revising an Index.

**Governmental regulatory actions could negatively affect your return on the notes.**

Governmental regulatory actions, including, but not limited to, sanctions-related actions by the U.S. or foreign governments, could cause the delisting of a stock included in a Reference Asset, depending on the nature of such governmental regulatory actions and the affected stock. If any governmental regulatory action results in the delisting of a stock included in a Reference Asset or even any uncertainty relating to a possible delisting, the value of the notes could be adversely affected, and transactions in, or holdings of, the notes may be prohibited under U.S. and/or foreign law. You may suffer significant losses if you are forced to divest the notes when the level of an Index declines.

**The historical performance of an Index should not be taken as an indication of its future performance.**

The level of an Index will determine the amount to be paid on the notes. The historical performance of an Index does not necessarily give an indication of its future performance. As a result, it is impossible to predict whether the level of an Index will rise or fall during the term of the notes. The level of an Index will be influenced by complex and interrelated political, economic, financial and other factors.

***Risks for Notes Linked to a Basket of Indices***

**The Indices comprising the Reference Asset may not move in tandem, and an increase in the level of one Basket Component may be offset by lower performance of one or more of the other Basket Components.**

Changes in the levels of one or more of the Basket Components may not correlate with changes in the levels of one or more of the other Basket Components. The levels of one or more Basket Components may increase, while the levels of one or more of the other Basket Components may decrease or not increase as much. Therefore, in calculating the value of the Basket at any time, increases in the level of one Basket Component may be moderated or wholly offset by decreases or lesser increases in the levels of one or more of the other Basket Components. If the weightings of the applicable Basket Components are not equal, adverse changes in the levels of the Basket Components which are more heavily weighted could have a greater impact upon your notes.

***Risks for Notes Linked to the Worst Performing of Multiple Indices***

**The notes are subject to the full risks of the worst performing Index and will be negatively affected if any Index performs poorly, even if the other Indices perform favorably.**

You are subject to the full risks of the worst performing Index. If the worst performing Index performs poorly, you will be negatively affected, even if the other Indices perform favorably. The notes are not linked to a basket composed of the Indices, where the better performance of one Index could offset the poor performance of the others. Instead, you are subject to the full risks of the worst performing Index on each Valuation Date. As a result, the notes are riskier than an alternative investment linked to only one of the Indices or linked to a basket composed of the Indices. You should not invest in the notes unless you understand and are willing to accept the full downside risks of the worst performing Index.

**You will be subject to risks resulting from the relationship between the Indices.**

It is preferable from your perspective for the Indices to be correlated with each other so that their levels will tend to increase or decrease at similar times and by similar magnitudes. By investing in the notes, you assume the risk that the Indices will not exhibit this relationship. The less correlated the Indices, the more likely it is that any one of the Indices will be performing poorly at any time over the term of the notes. All that is necessary for the notes to perform poorly is for one of the Indices to perform poorly; the performance of the better performing Indices is not relevant to your return on the notes. It is impossible to predict what the relationship between the Indices will be over the term of

------

the notes. Each Index may represent a different equity market, and the different equity markets may not perform similarly over the term of the notes.

***Risks for Notes Linked to the Russell 2000<sup>®</sup> Index, the S&P MidCap 400<sup>®</sup> Index or Any Other Index That Tracks Securities Related to Small and Mid-Capitalization Companies***

**The notes will be subject to risks associated with small-capitalization or mid-capitalization companies.**

The relevant Index will track companies that may be considered small-capitalization or mid-capitalization companies. These companies often have greater stock price volatility, lower trading volume and less liquidity than large-capitalization companies and therefore the level of the relevant Index may be more volatile than an investment in stocks issued by larger companies. Stock prices of small-capitalization or mid-capitalization companies may also be more vulnerable than those of larger companies to adverse business and economic developments, and the stocks of small-capitalization or mid-capitalization companies may be thinly traded, making it difficult for the relevant Index to track them. In addition, small-capitalization or mid-capitalization companies are often less stable financially than large-capitalization companies and may depend on a small number of key personnel, making them more vulnerable to loss of personnel. Small-capitalization or mid-capitalization companies are often subject to less analyst coverage and may be in early, and less predictable, periods of their corporate existences. These companies tend to have smaller revenues, less diverse product lines, smaller shares of their product or service markets, fewer financial resources and competitive strengths than large-capitalization companies, and are more susceptible to adverse developments related to their products.

***Risks for Notes Linked to the EURO STOXX 50<sup>®</sup> Index, the EURO STOXX<sup>®</sup> Banks Index, the FTSE<sup>®</sup> 100 Index, the Hang Seng Index, the MSCI Brazil Index, the MSCI EAFE<sup>®</sup> Index, the MSCI Emerging Markets Index, the MSCI Europe Index, the Nasdaq-100 Index<sup>®</sup>, the Nikkei Stock Average Index, the Swiss Market Index<sup>®</sup>, the TOPIX<sup>®</sup> Index, or Any Other Index That Tracks Foreign Securities***

**The notes will be subject to risks associated with non-U.S. companies.**

An investment in securities linked to the level of an Index that tracks the common stocks of non-U.S. companies involves risks associated with the home countries of such non-U.S. companies. The prices of such non-U.S. companies' common stocks may be affected by political, economic, financial and social factors in the home country of each such non-U.S. company, including changes in such country's government, economic and fiscal policies, currency exchange laws or other laws or restrictions, which could adversely affect the value of the notes.

The foreign securities tracked by such an Index may have less liquidity and could be more volatile than the securities traded in U.S. or other longer-established securities markets. Direct or indirect government intervention to stabilize the relevant foreign securities markets, as well as cross shareholdings in foreign companies, may adversely affect trading levels or prices and volumes in those markets. The other special risks associated with foreign securities may include, but are not limited to: less liquidity and smaller market capitalizations; less rigorous regulation of securities markets; different accounting and disclosure standards; governmental interference; currency fluctuations; higher inflation; and social, economic and political uncertainties. These factors may adversely affect the performance of the Index and, as a result, the value of the notes.

**Time differences between the domestic and foreign markets and New York City may create discrepancies between the prices of the securities included in an Index and the value of the notes.**

Time differences between the domestic and foreign markets may result in discrepancies between the prices of the securities included in an Index and the value of the notes. To the extent that U.S. markets are closed while markets for the securities included in an Index remain open, significant price or rate movements of these securities may take place that will not be reflected immediately in the value of the notes. In addition, there may be periods when the relevant foreign markets are closed for trading, causing the level of the Index to remain unchanged for multiple Trading Days (as defined below) in New York City.

------

***Risks for Notes Linked to the EURO STOXX 50<sup>®</sup> Index, the EURO STOXX<sup>®</sup> Banks Index, the FTSE<sup>®</sup> 100 Index, the Hang Seng Index, the MSCI Brazil Index, the MSCI Europe Index, the Nikkei Stock Average Index, the Swiss Market Index<sup>®</sup>, the TOPIX<sup>®</sup> Index, or Any Other Index That Tracks Foreign Securities And That Is Not Adjusted for Exchange Rate Changes.***

**The notes will not be adjusted for changes in exchange rates.**

Although the equity securities that are included in the relevant Index are traded in the foreign currencies, and your notes are denominated in U.S. dollars, such Index and the amount payable on the notes will not be adjusted for changes in the exchange rates between the U.S. dollar and the foreign currencies. Changes in exchange rates, however, may also reflect changes in the foreign economies that in turn may affect the level of such Index, and therefore the return on your notes. The amount we will pay in respect of your notes will be determined solely in accordance with the procedures described in the applicable pricing supplement.

***Risks for Notes Linked to the MSCI EAFE<sup>®</sup> Index, the MSCI Emerging Markets Index, or Any Other Index That Tracks Foreign Securities And That Is Adjusted for Exchange Rate Changes.***

**The notes will be subject to currency exchange risk.**

The prices of the securities included in the relevant Index will be converted into U.S. dollars for purposes of calculating the level of such Index. As a result, your notes will be exposed to currency exchange rate risk with respect to each of the currencies in which the equity securities included in such Index trade. Your net exposure will depend on the extent to which such currencies strengthen or weaken against the U.S. dollar and the relative weight of the equity securities included in such Index denominated in each such currency. If, taking into account such weighting, the U.S. dollar strengthens against such currencies, the level of such Index will be adversely affected and, depending on the terms of your notes, the return on the notes may be reduced.

Of particular importance to potential currency exchange risk are:

&nbsp;&nbsp;&nbsp;&nbsp;•the volatility of the exchange rate between the U.S. dollar and relevant currencies in which the stocks or other securities that make up the relevant Index are denominated;

&nbsp;&nbsp;&nbsp;&nbsp;•existing and expected rates of inflation;

&nbsp;&nbsp;&nbsp;&nbsp;•existing and expected interest rate levels;

&nbsp;&nbsp;&nbsp;&nbsp;•the balance of payments in the relative countries and between each country and its major trading partners; and

&nbsp;&nbsp;&nbsp;&nbsp;•the extent of governmental surpluses or deficits in the component countries and the United States.

All of these factors are in turn sensitive to the monetary, fiscal and trade policies pursued by the governments of various component countries and the United States and other countries important to international trade and finance.

**Regulators are investigating potential manipulation of published currency exchange rates.**

It has been reported that the U.K. Financial Conduct Authority and regulators from other countries are in the process of investigating the potential manipulation of published currency exchange rates. If such manipulation has occurred or is continuing, certain published exchange rates may have been, or may be in the future, artificially lower (or higher) than they would otherwise have been. Any such manipulation could have an adverse impact on the return on your notes and the trading market for your notes. In addition, we cannot predict whether any changes or reforms affecting the determination or publication of exchange rates or the supervision of currency trading will be implemented in connection with these investigations. Any such changes or reforms could also adversely impact the return on your notes.

***Risks for Notes Linked to the Hang Seng Index, the MSCI Emerging Markets Index, or Any Other Index That Tracks Foreign Securities In Emerging Markets.***

**There are risks associated with emerging markets.**

An investment in the notes will involve risks that are associated with investments that are linked to the equity securities of issuers from emerging markets. Many of the issuers included in the relevant Index are based in nations that are undergoing rapid institutional change, including the restructuring of economic, political, financial and legal systems. The regulatory and tax environments in these nations may be subject to change without review or appeal

------

and many emerging markets suffer from underdevelopment of their capital markets and their tax systems. In addition, in some of these nations, issuers of the relevant securities face the threat of expropriation of their assets and/or nationalization of their businesses. It may be more difficult for an investor in these markets to monitor investments in these companies, because these companies may be subject to fewer disclosure requirements than companies in developed markets, and economic and financial data about some of these countries may be unreliable.

***Other Risk Factors for an Index***

The applicable pricing supplement may set forth additional risk factors as to a specific Index that you should review prior to purchasing the notes.

------

**USE OF PROCEEDS AND HEDGING**

The net proceeds from the sale of the notes will be used as described under "Use of Proceeds" in the accompanying prospectus supplement and prospectus and to hedge market risks of the Bank associated with its obligation to make any payments on the notes.

We may hedge our obligations under the notes by, among other things, purchasing securities, futures, options or other derivative instruments with returns linked or related to changes in the value of the Reference Asset, and we may adjust these hedges by, among other things, purchasing or selling securities, futures, options or other derivative instruments at any time. Our cost of hedging will include the projected profit that our counterparty expects to realize in consideration for assuming the risks inherent in hedging our obligations under the notes. Because hedging our obligations entails risk and may be influenced by market forces beyond our or our counterparty's control, such hedging may result in a profit that is more or less than expected, or could result in a loss. It is possible that we could receive substantial returns from these hedging activities while the value of the notes decreases.

We expect to hedge our obligations under the notes through one of our affiliates and/or another unaffiliated counterparty.

We have no obligation to engage in any manner of hedging activity and we will do so solely at our discretion and for our own account. No holder of the notes will have any rights or interest in our hedging activity or any positions we or any unaffiliated counterparty may take in connection with our hedging activity. The hedging activity discussed above may adversely affect the value of the notes from time to time. See "Risk Factors—The Bank's initial estimated value of the notes will be lower than the initial issue price (price to public) of the notes" and "—Certain business, trading and hedging activities of us, the agents, and our respective affiliates may create conflicts with your interests and could potentially adversely affect the value of the notes" above.

**The Dow Jones Industrial Average<sup>®</sup>**

The Dow Jones Industrial Average<sup>®</sup> (the "**INDU**") is a price-weighted index of 30 U.S. blue-chip companies. The INDU covers all industries except transportation and utilities. The INDU was launched on May 26, 1896 with a base date of May 26, 1896. The INDU is published by S&P Dow Jones Indices LLC ("**SPDJI**") and is reported by Bloomberg L.P. ("**Bloomberg**") under the ticker symbol "INDU."

*Index Construction and Maintenance*

The INDU is maintained by the "Averages Committee," which is composed of three representatives of SPDJI and two representatives of *The Wall Street Journal*. The Averages Committee meets regularly to review pending corporate actions that may affect index constituents, statistics comparing the composition of the INDU to the market, companies that are being considered as candidates for addition to the INDU and any significant market events. In addition, the Averages Committee may revise index policy covering rules for selecting companies, treatment of dividends, share counts or other matters.

The index universe for the INDU consists of securities in the S&P 500<sup>®</sup> Index excluding stocks classified under Global Industry Classification Standard ("**GICS<sup>®</sup>**") code 2030 (Transportation) and 55 (Utilities). While stock selection is not governed by quantitative rules, a stock typically is added only if the company has an excellent reputation, demonstrates sustained growth and is of interest to a large number of investors. Companies should be incorporated and headquartered in the United States. In addition, a plurality of revenues should be derived from the United States. Maintaining adequate sector representation within the index is also a consideration in the selection process for the INDU.

Changes to the INDU 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. Constituent changes are typically announced one to five days before they are scheduled to be implemented.

***Index Computation***

The INDU is a price-weighted index rather than a market capitalization-weighted index and therefore INDU constituent weights are determined solely by the prices of the constituent stocks in the INDU.

The formula to calculate the INDU is:

*Index level* = ![](image_002.jpg)

where,

P = the price of each constituent stock in the index

Shares outstanding are set to a uniform number throughout the INDU and the index divisor is adjusted for any price impacting corporate action on one of its member stocks; this includes price adjustments, special dividends, stock splits and rights offerings. The index divisor will also adjust in the event of an addition to or deletion from the index. The INDU is calculated without adjustments for regular cash dividends.

Corporate actions (such as stock splits, stock dividends, and rights offerings) are applied after the close of trading on the day prior to the ex-date. Any potential impact of a spin-off on constituents of the INDU is evaluated by the Averages Committee on a case-by-case basis.

**The EURO STOXX 50<sup>®</sup> Index**

***Index Composition and Maintenance***

The stocks in the represented Eurozone countries are ranked in terms of 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 EURO STOXX TMI, which covers 95% of the free-float market capitalization of the represented Eurozone countries. If the next highest-ranked stock brings the coverage closer to 60% in absolute terms, then it is also added to the selection list. All current stocks in the SX5E are added to the selection list. All of the stocks on the selection list are then ranked in terms of free-float market capitalization to produce the final index selection list. The largest 40 stocks on the selection list are selected; the remaining 10 stocks are selected from the largest remaining current stocks ranked between 41 and 60; if the number of stocks selected is still below 50, then the largest remaining stocks are selected until there are 50 stocks. The minimum liquidity criteria of the EURO STOXX TMI also applies to the selection of index components.

The index components are subject to a capped maximum index weight of 10%, which is applied on a quarterly basis.

The composition of the SX5E is reviewed annually in September. The review cut-off date is the last Trading Day of August.

The free-float factors for each component stock used to calculate the SX5E, as described below, are reviewed, calculated, and implemented on a quarterly basis and are fixed until the next quarterly review.

The SX5E is subject to a "fast exit rule." The index components are monitored for any changes based on the monthly selection list ranking (i.e., on an ongoing monthly basis). A component is deleted from the SX5E if: (a) it ranks 75 or below on the monthly selection list and (b) it ranked 75 or below on the selection list of the previous month. The highest-ranked stock that is not an index component will replace it. Changes will be implemented on the close of the fifth Trading Day of the month, and are effective the next Trading Day.

The SX5E is also reviewed on an ongoing basis. Corporate actions (including IPOs, mergers and takeovers, spin-offs, delistings, and bankruptcy) that affect the index composition are immediately reviewed. Any changes are announced, implemented, and effective in line with the type of corporate action and the magnitude of the effect.

A deleted stock is replaced immediately to maintain the fixed number of 50 component stocks. If a stock is deleted in between regular review dates but is still a component of the EURO STOXX TMI, then the stock will remain in the SX5E until the next regular review.

***Index Calculation***

The SX5E is calculated with the "**Laspeyres formula**," which measures the aggregate price changes in the component stocks against a fixed base quantity weight. The formula for calculating the index level can be expressed as follows:

Index = <u> Free float market capitalization of the index </u> <br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Divisor of the index

The "free float market capitalization of the index" is equal to the sum of the product of the price, number of shares outstanding, free float factor, weighting cap factor and exchange rate from local currency to index currency, for each component stock as of the time the SX5E is being calculated.

------

The SX5E is also subject to a divisor, which is adjusted to maintain the continuity of the index levels across changes due to corporate actions, such as the deletion and addition of stocks, the substitution of stocks, stock dividends, and stock splits.

Neither we nor any of our affiliates, including the selling agent, accepts any responsibility for the calculation, maintenance, or publication of, or for any error, omission, or disruption in, the SX5E or any successor to the SX5E. STOXX does not guarantee the accuracy or the completeness of the SX5E or any data included in the SX5E. STOXX assumes no liability for any errors, omissions, or disruption in the calculation and dissemination of the SX5E. STOXX disclaims all responsibility for any errors or omissions in the calculation and dissemination of the SX5E or the manner in which the SX5E is applied in determining the amount payable on the notes at maturity.

***License Agreement***

We have entered into an agreement with STOXX providing us and certain of our affiliates or subsidiaries identified in that agreement with a non-exclusive license and, for a fee, with the right to use the SX5E, which is owned and published by STOXX, in connection with certain securities, including the notes.

**The EURO STOXX<sup>®</sup> Banks Index**

***Index Composition and Maintenance***

The SX7E is one of the 20 EURO STOXX<sup>®</sup> Supersector indices that compose the STOXX<sup>®</sup> Europe 600 Index. The STOXX<sup>®</sup> Europe 600 Index contains the 600 largest stocks traded on the major exchanges of 17 European countries and is organized into the following 20 supersectors: technology, telecommunications, health care, banks, financial services, insurance, real estate, automobiles and parts, consumer products and services, media, retail, travel and leisure, food, beverage and tobacco, personal care, drug and grocery stores, construction and materials, industrial goods and services, basic resources, chemicals, energy, and utilities. The SX7E includes companies in the banks supersector, which tracks companies providing a broad range of financial services, including retail banking, loans and money transmissions.

The SX7E is weighted by free float market capitalization. All components are subject to a 30% capping for the largest company and a 15% capping for the second-largest company. Free float weights are reviewed quarterly.

The composition of each of the EURO STOXX<sup>®</sup> Supersector indices is reviewed quarterly. Changes to the component stocks are implemented on the third Friday in each of March, June, September and December and are effective the following trading day. All index components will be adjusted for corporate actions.

***Index Calculation***

The SX7E is calculated with the Laspeyres formula. The formula for calculating the index value can be expressed as follows:

Index = <u>Free float market capitalization of the SX7E</u> <br> Divisor of the SX7E

The "free float market capitalization of the SX7E" is equal to the sum of the product of the price, number of shares, free float factor and weighting cap factor for each component stock as of the time the SX7E is being calculated.

The SX7E is also subject to a divisor, which is adjusted to maintain the continuity of SX7E values despite changes due to corporate actions.

***License Agreement***

We have entered into an agreement with STOXX providing us and certain of our affiliates or subsidiaries identified in that agreement with a non-exclusive license and, for a fee, with the right to use the SX7E, which is owned and published by STOXX, in connection with certain securities, including the notes.

STOXX and its Licensors have no relationship to us, other than the licensing of the SX7E and the related trademarks for use in connection with the notes.

STOXX and its Licensors do not sponsor, endorse, sell or promote the notes; recommend that any person invest in the notes; have any responsibility or liability for or make any decisions about the timing, amount or pricing of the notes; have any responsibility or liability for the administration, management or marketing of the notes; or consider the needs of the notes or the owners of the notes in determining, composing or calculating the SX7E or have any obligation to do so.

STOXX and its Licensors will not have any liability in connection with the notes. Specifically, STOXX and its Licensors do not make any warranty, express or implied and disclaim any and all warranty about: the results to be obtained by the notes, the owners of the notes or any other person in connection with the use of the SX7E and the data included in the SX7E; the accuracy or completeness of the SX7E and its data; and the merchantability and the fitness for a particular purpose or use of the SX7E and its data. STOXX and its Licensors will have no liability for any errors, omissions or interruptions in the SX7E or its data. Under no circumstances will STOXX or its Licensors be liable for any lost profits or indirect, punitive, special or consequential damages or losses, even if STOXX or its Licensors knows that they might occur.

**The FTSE<sup>®</sup> 100 Index**

The FTSE<sup>®</sup> 100 Index (the "**UKX**") is a market-capitalization weighted index calculated, published and disseminated by FTSE Russell. The UKX is designed to measure the composite performance of the 100 largest UKlisted blue-chip companies that pass screening for size and liquidity traded on the London Stock Exchange Group plc (the "**LSE**"). The UKX was launched on January 3, 1984 and has a base date of December 30, 1983. The UKX is reported by Bloomberg under the ticker symbol "UKX."

***Index Composition***

Only equity shares listed on the Equity Shares (commercial companies) or Closed-ended investment fund categories, as defined by the Financial Conduct Authority in its Listing Rules Sourcebook, which have been admitted to trading on the London Stock Exchange with a sterling, euro or U.S. dollar denominated trading price on Stock Exchange Electronic Trading Service are eligible for inclusion in the UKX. All securities in the index universe are assigned a nationality. Only companies assigned U.K. nationality are eligible for inclusion in the UKX.

Eligible securities are required to pass the following screens before being added to the UKX:

&nbsp;&nbsp;&nbsp;&nbsp;●*Price*: there must be an accurate and reliable price for the purposes of determining the market value of a company.

&nbsp;&nbsp;&nbsp;&nbsp;●*Minimum voting rights*: companies are required to have greater than 5% of the company's voting rights in the hands of unrestricted shareholders.

&nbsp;&nbsp;&nbsp;&nbsp;●*Investability weightings*: constituents of the UKX are adjusted for free float and foreign ownership limits (where applicable to U.K. investors). Free float is calculated using available published information rounded to 12 decimal places. Companies with a free float of 5% or below are excluded from the UKX. To be eligible for inclusion in UKX, a security must have a minimum free float of 10% if the issuing company is U.K. incorporated and 25% if it is non-U.K. incorporated. However, a new company may be initially included in the UKX with a free float below the above parameters (provided it is above 5%) where the free float calculation has restricted shares solely because they are subject to a lock-in clause of 12 months or less from the company's first day of trading, but that would in all other respects be considered part of a company's free float. New companies with an initial free float of 5% or below are not eligible for inclusion in the UKX.

&nbsp;&nbsp;&nbsp;&nbsp;●*Liquidity*: each security will be tested for liquidity annually in June by calculation of its monthly median of daily trading volume. For the annual test, liquidity will be calculated from the first business day in May of the previous year to the last business day of April in the current year. For each month, the daily volume for each security is calculated as a percentage of the shares in issue for that day adjusted by the free float at the end of the month. These daily values are then ranked in descending order and the median is taken by selecting the value for the middle ranking day if there is an odd number of days and the mean of the middle two if there is an even number of days:

oSecurities which do not turnover at least 0.025% of their shares in issue (after the application of any investability weightings) based on their monthly median for at least ten of the twelve months prior to the annual index review, will not be eligible for inclusion in the UKX until the next annual review.

oAn existing constituent which does not turnover at least 0.015% of its shares in issue (after the application of any investability weightings) based on its monthly median per month for at least eight of the twelve months prior to the annual index review will be removed and will not be eligible for inclusion in the UKX until the next annual review.

oNew issues which do not have a twelve month trading record must have a minimum 20 day trading record when reviewed. They must turnover at least 0.025% of their shares in issue (after the application of any investability weightings) based on their monthly median each month, on a pro-rata basis since premium listing or U.K. Nationality allocation date if non-U.K. incorporated

***Index Calculation***

The UKX is an arithmetic weighted index where the weights are the market capitalization of each company. The UKX is calculated as the summation of the free float adjusted market values (or capitalizations) of all companies within the UKX divided by the divisor. On the base date, the divisor was calculated as the sum of the market capitalizations of the UKX constituents divided by the initial index value of 1,000. The divisor is subsequently adjusted for any capital changes in the UKX constituents. In order to prevent discontinuities in the UKX in the event of a corporate action or change in constituents it is necessary to make an adjustment to the prices used to calculate the UKX to ensure that the change in the UKX between two consecutive dates reflects only market movements rather than including changes due to the impact of corporate actions or constituent changes. This ensures that the index values remain comparable over

------

time and that changes in the level of the UKX properly reflect the change in value of a portfolio of UKX constituents with weights the same as in the UKX. The adjustment used by FTSE Russell is based on the Paasche formula (also known as the current-weighted formula) which adjusts the divisor for the UKX for the day before a corporate action and calculates the change from that adjusted index to the index for the following day in which the corporate action occurs.

***Index Maintenance***

The UKX is reviewed on a quarterly basis in March, June, September and December based on data from the close of business on the Tuesday before the first Friday of the review month. Securities eligible for inclusion in the UKX will comprise the Monitored List. At the periodic review, all securities including in the Monitored List will be ranked by full market capitalization (i.e., before the application of investability weightings) from largest to smallest. A security will be inserted if it rises to 90<sup>th</sup> or above on the Monitored List, and a security will be deleted if it falls to 111<sup>th</sup> or below on the Monitored List. Where a greater number of companies qualify to be inserted in the UKX than those qualifying to be deleted, the lowest ranking constituents presently included in the UKX 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 UKX will be inserted to match the number of companies being deleted at the periodic review.

Where a UKX constituent is scheduled to be deleted after the periodic review changes have been announced but before they have been implemented, the highest ranking constituent of the FTSE All-Share (which is not currently a member of the UKX) is selected as the replacement company. However, if that replacement company is already scheduled to be added as part of the index review, then the next highest-ranking company is selected as the replacement. Where a company being deleted is already due to be replaced in the UKX as part of the periodic review, it will be replaced by the largest company previously announced as a review addition to the index. In other words, the review addition will be brought forward and implemented concurrent with the intra-quarter deletion.

A new security (IPO) will be added to the UKX outside a quarterly review if it satisfies the eligibility criteria and the screens other than the liquidity screen and its full market capitalization (i.e. before the application of any investability weighting) using the closing price on the first day of official non-conditional trading is greater than the Fast Entry Level. Fast Entry Level means the company full market capitalization (i.e., before the application of individual constituent investability weightings) must rank at position 90<sup>th</sup> or above in the monitored list; and the security investable market capitalization (i.e., after the application of any investability weighting) must amount to or be greater than GBP 1 billion. The security which is the lowest ranking constituent of the UKX will be selected for removal.

***License Agreement***

CIBC or one of its affiliates has entered into a non-exclusive license agreement with FTSE, whereby CIBC and its affiliates and subsidiary companies and certain of their affiliates, in exchange for a fee, will be permitted to use the UKX, which is owned and published by FTSE, in connection with certain products, including the notes.

Neither FTSE nor the LSE makes any representation or warranty, express or implied, to the owners of the notes or any member of the public regarding the advisability of investing in structured products generally or in the notes particularly, or the ability of the UKX to track general stock market performance. FTSE and the LSE's only relationship with CIBC is the licensing of certain trademarks and trade names of FTSE, respectively, without regard to us or the notes. FTSE and the LSE have no obligation to take the needs of us or the holders of the notes into consideration in determining, composing or calculating the UKX. Neither FTSE nor the LSE is responsible for and has not participated in the determination of the timing, price or quantity of the notes to be issued or in the determination or calculation of the amount due at maturity of the notes. Neither FTSE nor the LSE has any obligation or liability in connection with the administration, marketing or trading of the notes.

The notes are not in any way sponsored, endorsed, sold or promoted by FTSE or the LSE, and neither FTSE nor the LSE makes any warranty or representation whatsoever, expressly or impliedly, either as to the results to be obtained from the use of the UKX and/or the figure at which the said component stands at any particular time on any particular day or otherwise. The UKX is compiled and calculated by FTSE. However, neither FTSE nor the LSE shall be liable (whether in negligence or otherwise) to any person for any error in the UKX and neither FTSE nor the LSE shall be under any obligation to advise any person of any error therein.

Constituents of the Hang Seng Composite LargeCap & MidCap Index as of index review data cut-off date are eligible as constituents of the HSI. If a company has multiple classes of listed shares that are with different stock codes, each class of shares will be considered separately. The HSI excludes stapled securities, secondary-listed foreign companies, biotech companies with stock names with the marker "B" and investment companies listed under chapter 21 of the listing rules of HKEX. In addition, to be eligible for selection, a company must meet the following eligibility criteria:

&nbsp;&nbsp;&nbsp;&nbsp;●Listing History Requirements: At least 3 months (counting up to the index review meeting date); and

&nbsp;&nbsp;&nbsp;&nbsp;●Turnover Requirements: minimum velocity of 0.1% on monthly basis.

For each security, its turnover velocity in each of the past 12 months is calculated using the following formula:

![](image_003.jpg)

For the denominator used in velocity calculation, free float-adjusted issued shares at the end of each month is used.

From the many eligible candidates, final selections are based on the following principles: (1) the market capitalization of the companies; (2) the turnover rankings of the companies; (3) the representation of the sub-sectors within the HSI directly reflecting that of the market; and (4) the financial performance of the companies, including profitability.

***Index Calculation***

The calculation methodology of the HSI is a free float-adjusted market capitalization weighting with a specified cap-level on individual constituents. The initial weightings of the constituents are derived in accordance with the free float-adjusted market value and are capped at 8%.

The formula for the index calculation is as follows:

&nbsp;&nbsp; ![](image_004.jpg)<br>

Where *P<sub>t</sub>* is the current price at day *t; P<sub>t-1</sub>* is the closing price at day *(t-1); IS* is the number of issued shares*; FAF is* the free-float-adjusted factor, which is between 0 and 1; *CF* is the capping factor, which is between 0 and 1; and *AF* is the adjustment factor*.*

The HSI is a price index without adjustments for cash dividends or warrant bonuses.

***Index Maintenance***

HSIL undertakes regular quarterly reviews of HSI constituents with data cut-off dates of the end of March, June, September and December each year. A quarterly review is normally completed within eight weeks after the end of each calendar quarter. In each review, there may or may not be constituent additions or deletions. Constituents failing to meet the market value requirement or turnover requirement may be considered for removal from the HSI. Even if they fulfil all the eligibility requirements, the smallest constituents and the constituents with lowest liquidity may be considered for removal from the HSI subject to the availability of appropriate replacement candidates. Quarterly data cut-off dates of constituent changes are the end of March, June, September and December. Constituent review results will be announced within eight weeks of data cut-off dates. Constituent changes will be effective according to index rebalancing schedule.

**The JPX-Nikkei Index 400**

The JPX-Nikkei Index 400 (the "**JPNK400**") is calculated, maintained and published by JPX Market Innovation & Research, Inc. ("**JPXI**") and Nikkei Inc. ("**Nikkei**") (collectively, for purposes of this section, the "**index sponsor**"). The JPNK400 is reported by Bloomberg under the ticker symbol "JPNK400."

The JPNK400 is composed of common stocks whose main market is the Tokyo Stock Exchange Prime Market, Standard Market or Growth Market (in principle). Stocks included in the JPNK400 are selected based on market capitalization, trading value, return on equity ("**ROE**"), and other factors, as described in more detail below. The JPNK400 was first calculated and published on January 6, 2014. The inception value of the JPNK400 was 10,000 on August 30, 2013.

***Index Composition and Maintenance***

The index components are selected based on the selection criteria applied as of the final business day of June (the "**base selection date**"). The calculation of the JPNK400 using the new constituents will begin at the final business day of August. The selection process and criteria are as follows:

(1) 1,000 stocks are selected from 1,200 stocks based on their trading value over the past three years and their market value on the base selection date. Stocks are excluded from selection if they fall under any of the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;●the stock has been listed for less than three years (excluding technical listings);

&nbsp;&nbsp;&nbsp;&nbsp;●the company fails to disclose its latest earnings report or internal control report, except in cases that the index sponsor deems this to be unavoidable;

&nbsp;&nbsp;&nbsp;&nbsp;●the company's liabilities have been in excess of its assets during any of the past three fiscal years;

&nbsp;&nbsp;&nbsp;&nbsp;●the company has had an operating loss in each of the past three fiscal years;

&nbsp;&nbsp;&nbsp;&nbsp;●the company has had a net loss in each of the past three fiscal years;

&nbsp;&nbsp;&nbsp;&nbsp;●the company's financials have disclosed doubt regarding its ability to continue as a going concern;

&nbsp;&nbsp;&nbsp;&nbsp;●there has been disclosure of insufficient financial controls or that it is not possible to release appraisal of internal controls in the internal control report pertaining to the most recent earnings period;

&nbsp;&nbsp;&nbsp;&nbsp;●the stock has been designated as a security to be delisted or security on special alert; or

&nbsp;&nbsp;&nbsp;&nbsp;●certain listing violations have occurred over the past year.

(2) Each stock is scored by (a) three-year average ROE (weighted 40%), (b) three-year cumulative operating profit (weighted 40%) and (c) market capitalization on the base selection date (weighted 20%).

For companies using Japanese general accounting standards, the 3-year average ROE shall be calculated as follows:

![](image_005.jpg)

Three-year cumulative operating profit is the sum of reported operating profit over the past three years.

The market capitalization of a stock is calculated based on the number of listed shares multiplied by its closing share price as of the annual base selection date.

(3) 400 stocks are selected by the final ranking with the scores calculated above in (2) and qualitative factors from the perspectives of corporate governance and disclosure. The final score for each stock equals the sum of the score calculated above in (2) plus the score from the qualitative factors. Stocks are ranked from highest to lowest based on their final scores, with the exception that stocks whose three-year average ROE or most recent ROE is negative or whose three-year cumulative operating profit is negative are moved to the bottom of the ranking. In the event of a tie in final scores, the stock with the higher market capitalization is ranked higher.

*Periodic Review.* Periodic review of constituents occurs annually in August with data on the base selection date. The top 440 issues are selected according to the rankings specified above from the eligible stocks as of the base selection date. If the number of constituents selected according to the rankings specified above does not reach 400, the top ranking stocks that meet the two conditions indicated below are selected until the number of constituents reaches 400.

------

-Either 3-year average ROE or latest ROE surpasses the median ranking; or

-Ranking is at or within the top ranking 400 stocks specified above.

If the number of selected stocks still does not reach 400, then the non-selected top ranking 400 stocks based on their final scores are selected according to the rankings of 3-year average ROE until the number of constituents reaches 400.

*Removal and inclusion of constituents in addition to periodic review.* If constituents are delisted, designated as securities to be delisted, or designated as securities on special alert outside of the periodic review, they are removed from the JPNK400. No supplementary inclusions are made to meet the intended number of constituents. If a constituent is delisted due to corporate events, such as consolidation, merger, acquisition or spin-offs, the resulting entity may be included as a constituent under certain conditions.

***Index Calculation***

The JPNK400 is calculated using free-float adjusted market value weighting and is calculated to two decimal places. The level of the JPNK400 equals the current total free-float adjusted market value divided by the base market value, and multiplied by the base point of 10,000. The market value is the sum of the number of shares of each constituent stock multiplied by its stock price. The base market value is adjusted to maintain continuity in the JPNK400 when the market value of constituents changes for non-market reasons. The weight of each index component is capped at 1.5% of the JPNK400, and if any component exceeds that weight, it is adjusted downwards at the time of the annual review. In case of delisting of the components due to a merger, bankruptcy, or other corporate event, new stocks are not added until the next annual review.

The free-float adjustment market value is determined by excluding the estimated number of listed shares that are deemed not to be available for trading in the market, using publicly available documents. Shares that are not treated as available are, among others, shares held by specified types of major shareholders, and shares held by board members and other representatives. The free-float weights are reviewed annually for each index component, with the announcement and effective date for each index component occurring on a quarterly basis, depending upon the relevant company's earnings release schedule. In addition to this annual review, the index sponsors may also adjust a company's free-float weight to reflect extraordinary events.

***License Agreement*** 

We expect to enter into an agreement with the index sponsor providing us with a non-exclusive license with the right to use the JPNK400 in exchange for a fee. The JPNK400 is the intellectual property of the index sponsor.

The index sponsor shall not be obligated to continuously publish the JPNK400 and shall not be liable for any errors, delays, or suspensions of the publication of the JPNK400. The index sponsor shall have the right to change the composition of the stocks included in the JPNK400, the calculation methodology of the JPNK400 or any other details of the JPNK400 and shall have the right to discontinue the publication of the JPNK400 at any time.

The U.S. dollar price return version of the MSCI Brazil Index is reported by Bloomberg under the ticker symbol "MXBR."

**The MSCI EAFE<sup>®</sup> Index** 

The MSCI EAFE<sup>®</sup> Index ("**MXEA**") is designed to measure equity market performance in developed market countries, excluding the United States and Canada. The MXEA is a free float-adjusted market capitalization equity index. The MXEA covers approximately 85% of the free float-adjusted market capitalization in each country. The MXEA is part of the MSCI Market Cap Weighted Indexes series and is an MSCI Global Investable Market Index. The MXEA is reported by Bloomberg under the ticker symbol "MXEA."

**The MSCI Emerging Markets Index** 

The MSCI Emerging Markets Index ("**MXEF**") is a free float-adjusted, capitalization-weighted index that is designed to measure the performance of the large- and mid-cap segments of emerging markets. The MXEF covers approximately 85% of the free float-adjusted market capitalization in each country. The MXEF is part of the MSCI Market Cap Weighted Indexes series and is an MSCI Global Investable Market Index. The MXEF is reported by Bloomberg under the ticker symbol "MXEF."

**The MSCI Europe Index** 

The MSCI Europe Index is a free float-adjusted, capitalization-weighted index that is designed to measure the performance of the large- and mid-cap segments of the developed markets in Europe. The MSCI Europe Index covers approximately 85% of the free float-adjusted market capitalization across the European developed markets equity universe. The U.S. dollar price return version of the MSCI Europe Index is reported by Bloomberg under ticker symbol "MXEU."

***General – MSCI Indices***

MSCI provides global equity indices that are designed to measure equity performance in international markets. In constructing these indices, MSCI applies its index construction and maintenance methodology across developed, emerging and frontier markets.

MSCI enhanced the methodology used in its international equity indices. The MSCI Standard and MSCI Small Cap Indices, along with the other MSCI equity indices based on them, transitioned to the Global Investable Market Indexes methodology described below. The transition was completed at the end of May 2008. The MSCI Standard Indices are composed of the MSCI Large Cap and Mid Cap Indices. The MSCI Global Small Cap Index transitioned to the MSCI Small Cap Index resulting from the Global Investable Market Indices methodology and contains no overlap with constituents of the transitioned MSCI Standard Indices. Together, the relevant MSCI Large Cap, Mid Cap, and Small Cap Indices make up the MSCI investable market index for each country, composite, sector, and style index that MSCI offers.

***Constructing the MSCI Global Investable Market Indices***

The MSCI Global Investable Market Indices are constructed and maintained at an individual market level. MSCI undertakes an index construction process for the MSCI Global Investable Market Indexes, which involves:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●defining the equity universe;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●determining the market investable equity universe for each market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●determining market capitalization size-segments for each market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●applying index continuity rules for the MSCI Standard Index; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●classifying securities under the GICS<sup>®</sup>.

*Defining the Equity Universe.* The equity universe is defined by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Identifying Eligible Equity Securities: all listed equity securities, including Real Estate Investment Trusts ("**REITs**") and certain income trusts listed in Canada are eligible for inclusion in the equity universe. Limited partnerships, limited liability companies, and business trusts, which are listed in the United States and are not structured to be taxed as limited partnerships, are likewise eligible for inclusion in the equity universe. Conversely, mutual funds, ETFs, equity derivatives, and most investment trusts are not eligible for inclusion in the equity universe.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Classifying Eligible Securities into the Appropriate Country: each company and its securities (i.e., share classes) are classified in only one country. Countries will be classified as Developed Markets ("**DM**"), Emerging Markets ("**EM**") or Frontier Markets ("**FM**").

*Determining the Market Investable Equity Universes.* A market investable equity universe for a market is derived by identifying eligible listings for each security in the equity universe and applying investability screens to individual companies and securities in the equity universe that are classified in that market. A market is equivalent to a single country, except in DM Europe, where all DM countries in Europe are aggregated into a single market for index construction purposes. Subsequently, individual DM Europe country indices within the MSCI Europe Index are derived from the constituents of the MSCI Europe Index under the Global Investable Market Indexes methodology.

In identifying eligible listings, a security may have a listing in the country where it is classified (i.e. "**local listing**") and/or in a different country (i.e. "**foreign listing**"). Securities may be represented by either a local listing or a foreign listing (including a depositary receipt) in the equity universe. A security may be represented by a foreign listing only if the following conditions are met:

&nbsp;&nbsp;&nbsp;&nbsp;●The security is classified in a country that meets the Foreign Listing Materiality Requirement, and

&nbsp;&nbsp;&nbsp;&nbsp;●The security's foreign listing is traded on an eligible stock exchange of: (a) a DM country if the security is classified in a DM country; (b) a DM or an EM country if the security is classified in an EM country; or (c) a DM, EM or FM country if the security is classified in an FM country.

The investability screens used to determine the investable equity universe in each market are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;●Equity Universe Minimum Size Requirement: this investability screen is applied at the company level. In order to be included in a market investable equity universe, a company must have the required minimum full market capitalization.

&nbsp;&nbsp;&nbsp;&nbsp;●Equity Universe Minimum Free Float-Adjusted Market Capitalization Requirement: this investability screen is applied at the individual security level. To be eligible for inclusion in a market investable equity universe, a security must have a free float-adjusted market capitalization equal to or higher than 50% of the equity universe minimum size requirement.

&nbsp;&nbsp;&nbsp;&nbsp;●DM and EM Minimum Liquidity Requirement: this investability screen is applied at the individual security level. To be eligible for inclusion in a market investable equity universe, a security must have adequate liquidity. The twelve-month and three-month Annual Traded Value Ratio, a measure that screens out extreme daily trading volumes and takes into account the free float-adjusted market capitalization of securities, together with the three-month frequency of trading are used to measure liquidity. Only one listing per security may be included in the market investable equity universe. In instances when a security has two or more eligible listings that meet the above liquidity requirements, then the following priority rules are used to determine which listing will be used for potential inclusion of the security in the market investable equity universe: (i) local listing; (ii) foreign listing in the same geographical region; and (iii) foreign listing in a different geographical region.

&nbsp;&nbsp;&nbsp;&nbsp;●Global Minimum Foreign Inclusion Factor Requirement: this investability screen is applied at the individual security level. To be eligible for inclusion in a market investable equity universe, a security's Foreign Inclusion Factor ("**FIF**") must reach a certain threshold. The FIF of a security is defined as the proportion of shares outstanding that is available for purchase in the public equity markets by international investors. This proportion accounts for the available free float of and/or the foreign ownership limits applicable to a specific

------

security (or company). In general, a security must have an FIF equal to or larger than 0.15 to be eligible for inclusion in a market investable equity universe.

&nbsp;&nbsp;&nbsp;&nbsp;●Minimum Length of Trading Requirement: this investability screen is applied at the individual security level. For an IPO to be eligible for inclusion in a market investable equity universe, the new issue must have started trading at least three months before the implementation of a semi-annual index review. This requirement is applicable to small new issues in all markets. Large IPOs are not subject to the minimum length of trading requirement and may be included in a market investable equity universe and the MSCI Standard Index outside of a quarterly or semi-annual index review (as described below).

&nbsp;&nbsp;&nbsp;&nbsp;●Minimum Foreign Room Requirement: this investability screen is applied at the individual security level. For a security that is subject to a Foreign Ownership Limit to be eligible for inclusion in a market investable equity universe, the proportion of shares still available to foreign investors relative to the maximum allowed (referred to as "**foreign room**") must be at least 15%.

&nbsp;&nbsp;&nbsp;&nbsp;●Financial Reporting Requirement: for any companies classified as belonging to the United States, the company must file a Form 10-K/10-Q to be eligible for inclusion in the U.S. investable equity universe.

*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, with the following free float-adjusted market capitalization market coverage target ranges:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Investable Market Index (Large + Mid + Small): 99%+1% or -0.5%

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Standard Index (Large + Mid): 85% ± 5%

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Large Cap Index: 70% ± 5%

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Mid Cap Index: The Mid Cap Index market coverage in each market is derived as the difference between the market coverage of the Standard Index and the Large Cap Index in that market.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Small Cap Index: The Small Cap Index market coverage in each market is derived as the difference between the free float-adjusted market capitalization coverage of the Investable Market Index and the Standard Index in that market.

*Index Continuity Rules for the Standard Indices.* In order to achieve index continuity, as well as to provide some basic level of diversification within a market index, and notwithstanding the effect of other index construction rules described in this section, a minimum number of five constituents will be maintained for a DM Standard Index and a minimum number of three constituents will be maintained for an EM Standard Index.

*Classifying 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, the GICS<sup>®</sup>. Under the GICS<sup>®</sup>, each company is assigned to one sub-industry according to its principal business activity. Therefore, a company can belong to only one industry grouping at each of the four levels of the GICS<sup>®</sup>.

***Maintenance of the MSCI Global Investable Market Indices***

The MSCI Global Investable Market Indexes are maintained with the objective of reflecting the evolution of the underlying equity markets and segments on a timely basis, while seeking to achieve index continuity, continuous investability of constituents and replicability of the indices, index stability and low index turnover. In particular, index maintenance involves:

(i) Quarterly Index Reviews ("**QIRs**") in February, May, August and November, which include:

&nbsp;&nbsp;&nbsp;&nbsp;●Updating the indices on the basis of a fully refreshed equity universe;

&nbsp;&nbsp;&nbsp;&nbsp;●Taking buffer rules into consideration for migration of securities across size and style segments; and

&nbsp;&nbsp;&nbsp;&nbsp;●Updating FIFs and number of shares.

The objective of the QIRs is to systematically reassess the various dimensions of the equity universe for all markets on a fixed quarterly timetable. During each QIR, 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:

&nbsp;&nbsp;&nbsp;&nbsp;●Updating the market investable equity universe;

&nbsp;&nbsp;&nbsp;&nbsp;●Recalculating the global minimum size references and global minimum size ranges;

&nbsp;&nbsp;&nbsp;&nbsp;●Reassessing the segment number of companies and the market size-segment cutoff;

&nbsp;&nbsp;&nbsp;&nbsp;●Assigning companies to the size-segments taking into account buffer zones; and

&nbsp;&nbsp;&nbsp;&nbsp;●Assessing conformity with final size-segment investability requirements.

(ii) 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.

***Calculation of the MSCI Global Investable Market Indices***

The MSCI Indices are calculated using the Laspeyres formula. As a general principle, today's index level is obtained by applying the change in the market performance to the previous period index level.

**The Nasdaq100 Index<sup>®</sup>**

The Nasdaq-100 Index<sup>®</sup> (the "**NDX**") is calculated and maintained by Nasdaq, Inc. ("**Nasdaq**"). The NDX includes 100 of the largest domestic and international non-financial companies listed on The Nasdaq Stock Market based on market capitalization. The NDX reflects companies across major industry groups including computer hardware and software, telecommunications, retail/wholesale trade and biotechnology. It does not contain securities of financial companies including investment companies. The NDX is reported by Bloomberg under the ticker symbol "NDX."

Launched in January 1985, the NDX represents the largest non-financial domestic and international securities listed on The Nasdaq Stock Market based on market capitalization. The NDX is calculated under a modified market capitalization-weighted methodology. The methodology is expected to retain in general the economic attributes of capitalization-weighting while providing enhanced diversification. To accomplish this, Nasdaq reviews the composition of the NDX on a quarterly basis and adjusts the weightings of NDX components using a proprietary algorithm, if certain pre-established weight distribution requirements are not met.

***Eligibility Criteria***

To be eligible for initial inclusion in the NDX, a security must meet the following criteria:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Eligible security types*. Eligible security types generally include American Depositary Receipts, common stocks, ordinary shares, and tracking stocks. Securities of REITs and special purpose acquisition companies are not eligible for index inclusion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Multiple classes of securities*. If an issuer has multiple security classes listed, all security classes are eligible.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Eligible exchanges*. The securities must be primarily listed on a U.S. Nasdaq-affiliated exchange.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Industry or sector eligibility*. The security must be classified as a non-financial company (any industry other than financials) according to the Industry Classification Benchmark, a product of FTSE International Limited that is used under license.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Market capitalization eligibility*. There is no market capitalization eligibility criterion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Liquidity eligibility*. Each security must have a minimum average daily traded value of at least $5 million (measured over the last three calendar months).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Seasoning eligibility.* The security must have traded for at least three full calendar months, not including the month of initial listing, on any U.S. Nasdaq-affiliated exchange, New York Stock Exchange (the "**NYSE**"), NYSE American or CBOE BZX. Eligibility is determined as of the constituent selection reference date, and includes that month. A security that was added to the index as the result of a spin-off event will be exempt from the seasoning requirement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Float eligibility criteria. There is no float eligibility criterion, although the modified market capitalization used for weighting purposes imposes a limitation on the weight of low-float securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●*Other eligibility criteria*. The issuer of the security generally may not currently be in bankruptcy proceedings. The issuer of the security generally may not have entered into a definitive agreement or other arrangement that would make it ineligible for index inclusion and where the transaction is imminent as determined by the index management committee.

***Index Constituent Selection***

A reconstitution is conducted on an annual basis, at which time all eligible issuers, ranked by market capitalization, are considered for index inclusion based on the following order of criteria.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.The top 75 ranked issuers will be selected for inclusion in the index.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Any other issuers that were already members of the index as of the reconstitution reference date and are ranked within the top 100 are also selected for inclusion in the index.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.In the event that fewer than 100 issuers pass the first two criteria, the remaining positions will first be filled, in rank order, by issuers currently in the index ranked in positions 101-125, as long as they were: (a) ranked in the top 100 at the previous reconstitution or replacement, (b) replacement issuers added since the previous reconstitution, or (c) spin-off issuers added since the previous reconstitution. In the event that fewer than

------

100 issuers pass the first three criteria, the remaining positions will be filled, in rank order, by any issuers ranked in the top 100 that were not already members of the index as of the reconstitution reference date.

***Index Calculation***

The NDX is a modified market capitalization-weighted index. The value of the NDX equals the aggregate value of the weights of each of the component securities multiplied by each such security's last sale price, and divided by the divisor of the NDX. The divisor serves the purpose of scaling such aggregate value to a lower order of magnitude, which is more desirable for reporting purposes. If trading in an index security is halted on its primary listing market, the most recent last sale price for that security is used for all index computations until trading on such market resumes. Likewise, the most recent last sale price is used if trading in a component security is halted on its primary listing market before the market is open.

***Index Maintenance***

*Deletion policy.* If, at any time other than an index reconstitution, Nasdaq determines that a component security is ineligible for index inclusion, that component security is removed as soon as practicable.

*Replacement policy.* Securities may be added to the NDX outside of the index reconstitution when there is a deletion. The component security (or all component securities under the same issuer, if appropriate) is replaced as soon as practicable if the issuer in its entirety is being deleted from the NDX. The issuer with the largest market capitalization that is not in the NDX and that meets all eligibility criteria as of the prior month end will replace the deleted issuer. Issuers that are added as a result of a spin-off are not replaced until after they have been included in a reconstitution.

For pending deletions set to occur soon after an index reconstitution and/or index rebalance effective date, Nasdaq may decide to remove a component security from the index in conjunction with the index reconstitution and/or index rebalance effective date.

*Corporate actions.* In the periods between scheduled index reconstitution and rebalancing events, individual component securities may be the subject to a variety of corporate actions and events that require maintenance and adjustments to the index.

***Index Rebalancing***

Under the methodology employed, on a quarterly basis coinciding with Nasdaq's quarterly scheduled weight adjustment procedures, the component securities are categorized as either "Large Stocks" or "Small Stocks" depending on whether their current percentage weights (after taking into account scheduled weight adjustments due to stock repurchases, secondary offerings or other corporate actions) are greater than, or less than or equal to, the average percentage weight in the NDX (i.e., as a 100-stock index, the average percentage weight in the NDX is 1%).

This quarterly examination will result in an index rebalancing if it is determined that: (1) the current weight of the single largest market capitalization component security is greater than 24% or (2) the "collective weight" of those component securities, the individual current weights of which are in excess of 4.5%, when added together, exceed 48%. In addition, Nasdaq may conduct a special rebalancing at any time if it is determined to be necessary to maintain the integrity of the NDX.

If either one or both of these weight distribution requirements are met upon quarterly review, or Nasdaq determines that a special rebalancing is required, a weight rebalancing will be performed. First, relating to weight distribution requirement (1) above, if the current weight of the single largest component security exceeds 24%, then the weights of all Large Stocks will be scaled down proportionately towards 1% by a sufficient amount for the adjusted weight of the single largest component security to be set to 20%. Second, relating to weight distribution requirement (2) above, for those component securities whose individual current weights or adjusted weights in accordance with the preceding step are in excess of 4.5%, if their "collective weight" exceeds 48%, then the weights of all Large Stocks will be scaled down proportionately towards 1% by a sufficient amount for the "collective weight," so adjusted, to be set to 40%.

**The Nikkei Stock Average Index**

The Nikkei Stock Average Index (the "**NKY**"), also known as the Nikkei, the Nikkei Index, or the Nikkei 225, is calculated, maintained and published by Nikkei. The NKY is reported by Bloomberg under the ticker symbol "NKY."

The NKY is an adjusted price weight index that measures the composite price performance of certain Japanese stocks. The NKY currently is based on 225 underlying stocks trading on the Tokyo Stock Exchange, Inc. ("**TSE**") representing a broad cross-section of Japanese industries. ETFs, REITs, preferred stocks, preferred securities and tracking stocks are excluded. All 225 components of the NKY are listed on the TSE Prime Market. Stocks listed on the TSE Prime Market are among the most actively traded stocks on the TSE. The index rules require that the 75 most liquid issues (one-third of the components of the NKY) be included in the NKY.

***Index Composition and Maintenance***

The NKY is reviewed twice a year with a base date at the end of January and July, and the result becomes effective in the beginning of April and October respectively. The maximum number of constituents reshuffled is 3. However, constituent changes due to corporate reorganizations near the time of periodic review are not subject to such limit. Stocks with high market liquidity are added and those with low liquidity are deleted. At the same time, to take into account changes in industry structure, the index sponsor examines the balance of the sectors, in terms of the number of constituents. Liquidity of a stock is assessed by the two measures: "trading value" and "magnitude of price fluctuation by volume," which is calculated as (High price/Low price) / Volume. Among stocks on the TSE Prime Market, the top 450 stocks in terms of liquidity are selected to form the "high liquidity group". Those constituents not in the high liquidity group are deleted. Those non-constituent stocks which are in the top 75 of the high liquidity group are added. After the liquidity deletions and additions, constituents are deleted and added to balance the number of constituents among sectors, and to make the total number of the constituents equal 225.

The 225 companies included in the NKY are divided into six sector categories: Technology, Financials, Consumer Goods, Materials, Capital Goods/Others and Transportation and Utilities. The six sector categories are divided into 36 industrial classifications as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Technology — Pharmaceuticals, Electric Machinery, Automobiles and Auto Parts, Precision Instruments, Communications;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Financials — Banking, Other Financial Services, Securities, Insurance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Consumer Goods — Fishery, Foods, Retail, Services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Materials — Mining, Textiles and Apparel, Paper and Pulp, Chemicals, Petroleum, Rubber, Glass and Ceramics, Steel, Nonferrous Metals, Trading Companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Capital Goods/Others — Construction, Machinery, Shipbuilding, Transportation Equipment, Other Manufacturing, Real Estate; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●Transportation and Utilities — Railway and Bus, Land Transport, Marine Transport, Air Transport, Warehousing, Electric Power, Gas.

Among the 450 "high liquidity" stocks, half of those that belong to any sector are designated as the "appropriate number of stocks" for that sector. The actual number of constituents in a sector is then compared with its "appropriate number," and if the actual number is larger or smaller than the "appropriate number," then components are deleted or added, as necessary. Stocks to be deleted are selected from stocks with lower liquidity and stocks to be added are selected from stocks with higher liquidity. Stocks selected according to the foregoing procedures are candidates for addition or deletion, as applicable, and the final determinations will be made by the index sponsor.

The NKY is also reviewed on an ongoing basis in response to extraordinary developments, such as bankruptcies or mergers. Any stock removed from the TSE Prime Market due to any of the following reasons will be removed from the NKY: (i) designated to be "securities to be delisted" or "securities on alert"; (ii) delisted due to corporate restructuring such as merger, share exchange or share transfer; or (iii) transfer to a market other than the Prime Market. In addition, component stocks designated as "securities under supervision" remain to be constituents at the time of designation. However, Nikkei may replace such a constituent with a pre-announcement when it is highly inappropriate to keep such stock as a constituent. Upon deletion of a stock from the NKY, the index sponsor will generally select as a replacement the most liquid stock that is both in the "high liquidity group" and in the same sector as the deleted

------

stock. When deletions are known in advance, replacements may be selected as part of the periodic review process or by using similar procedures.

***Index Calculation***

The NKY is an adjusted price-weighted index (i.e., a stock's weight in the NKY is based on its price per share rather than the total market capitalization of the issuer) where the sum of the constituent stock prices, adjusted by the presumed par value, is divided by a divisor.

The NKY is calculated as a weighted price average where the sum of the constituent stock prices adjusted by the price adjustment factor is divided by the divisor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●adjusted stock price = stock price ![](image_006.jpg) price adjustment factor

&nbsp;&nbsp;&nbsp;&nbsp;●The level of the NKY = sum of adjusted stock price / divisor

For a constituent to which a capping ratio is applied, price adjustment factor will be replaced by capped price adjustment factor.

In order to maintain continuity in the NKY in the event of certain changes due to non-market events, the divisor is changed. The non-market factors affecting the component stocks, such as the addition or deletion of stocks, substitution of stocks, stock splits or distributions of assets to stockholders, the divisor used in calculating the NKY is adjusted in a manner designed to prevent any instantaneous change or discontinuity in the level of the NKY. Thereafter, the divisor remains at the new value until a further adjustment is necessary as the result of another change. As a result of such change affecting any component stock, the divisor is adjusted in such a way that the sum of all share prices immediately after such change multiplied by the applicable weight factor and divided by the new divisor (i.e., the level of the NKY immediately after such change) will equal the level of the NKY immediately prior to the change. The price adjustment factor may also be changed for large scale splits and reverse splits to keep its continuity. The divisor is not changed so long as the adjusted price is unchanged before and after such split.

***License Agreement***

We will enter into an agreement with Nikkei providing us with a non-exclusive license with the right to use the NKY in exchange for a fee. The NKY is the intellectual property of Nikkei. "Nikkei," "Nikkei 225," "Nikkei Stock Average" and "Nikkei Average" are the service marks of Nikkei. Nikkei reserves all the rights, including copyright, to the NKY.

Nikkei does not make any warranty or representation whatsoever, express or implied, either as to the results to be obtained as to the use of the NKY or the figure at which the NKY stands at any particular day or otherwise. The NKY is compiled and calculated solely by Nikkei. However, Nikkei shall not be liable to any person for any error in the NKY and Nikkei shall not be under any obligation to advise any person, including a purchaser or seller of the notes, of any error therein. Nikkei shall be entitled to change the details of the NKY and to suspend the announcement thereof. In addition, Nikkei gives no assurance regarding any modification or change in any methodology used in calculating the NKY and is under no obligation to continue the calculation, publication and dissemination of the NKY.

**The Russell Indices**

Each of the Russell 1000<sup>®</sup> Index, the Russell 2000<sup>®</sup> Index and the Russell 3000<sup>®</sup> Index (each, a "**Russell U.S. index**" and collectively, the "**Russell U.S. indices**") is calculated, maintained and published by FTSE Russell, which is wholly owned by London Stock Exchange Group.

**The Russell 1000<sup>®</sup> Index** 

The Russell 1000<sup>®</sup> Index measures the performance of the large-cap segment of the U.S. equity market. It is a subset of the Russell 3000<sup>®</sup> Index and includes approximately 1,000 of the largest securities in the U.S. equity market. The Russell 1000<sup>®</sup> Index is reported by Bloomberg under the ticker symbol "RIY."

**The Russell 2000<sup>®</sup> Index** 

The Russell 2000<sup>®</sup> Index measures the performance of the small-cap segment of the U.S. equity market. It is a subset of the Russell 3000<sup>®</sup> Index and includes approximately 2,000 of the smallest securities in the U.S. equity market. The Russell 2000<sup>®</sup> Index is reported by Bloomberg under the ticker symbol "RTY."

**The Russell 3000<sup>®</sup> Index** 

The Russell 3000<sup>®</sup> Index measures the performance of the largest 3,000 U.S. companies representing approximately 98% of the investable U.S. equity market, as of the most recent reconstitution. The Russell 3000<sup>®</sup> Index is constructed to provide a comprehensive, unbiased and stable barometer of the broad market and is completely reconstituted annually to ensure new and growing equities are included. The Russell 3000<sup>®</sup> Index is reported by Bloomberg under the ticker symbol "RAY."

***Defining Eligible Securities***

All companies that are determined to be part of the U.S. equity market under FTSE Russell's country-assignment methodology are included in the Russell U.S. indices. If a company is incorporated in, has a stated headquarters location in, and also trades in the same country (American Depositary Receipts and American Depositary Shares are not eligible), the company is assigned to the equity market of its country of incorporation. If any of the three do not match, FTSE Russell then defines three Home Country Indicators ("**HCI**"): country of incorporation, country of headquarters, and country of the most liquid exchange as defined by two-year average daily dollar trading volume from all exchanges within a country. Using the HCIs, FTSE Russell cross-compares the primary location of the company's assets with the three HCIs. If the primary location of the company's assets matches any of the HCIs, then the company is assigned to its primary asset location. If there is insufficient information to determine the country in which the company's assets are primarily located, FTSE Russell will use the primary location of the company's revenues for the same cross-comparison and will assign the company to the appropriate country in a similar fashion. FTSE Russell uses an average of two years of assets or revenue data for analysis to reduce potential turnover. If conclusive country details cannot be derived from assets or revenue, FTSE Russell assigns the company to the country where its headquarters are located unless the country is a Benefit Driven Incorporation country; in which case, the company will be assigned to the country of its most liquid stock exchange. For any companies incorporated or headquartered in a U.S. territory, including countries such as Puerto Rico, Guam, and U.S. Virgin Islands, a U.S. HCI is assigned. If a company is designated as a Chinese "N Share," it will not be considered for inclusion within the Russell U.S. indices. An "N Share" is a company incorporated outside of mainland China that trades on the NYSE, the Nasdaq exchange or the NYSE American. An N Share will have a headquarter or principle executive office or its establishment in mainland China, with a majority of its revenues or assets derived from the People's Republic of China.

All securities eligible for inclusion in Russell U.S. indices must trade on an eligible U.S. exchange. The eligible U.S. exchanges are: CBOE, NYSE, NYSE American, Nasdaq, ARCA. Securities traded on pink-sheets and any other over-the-counter ("**OTC**") markets are not eligible for inclusion, including securities for which prices are displayed on the FINRA ADF.

Preferred and convertible preferred stock, redeemable shares, participating preferred stock, warrants, rights, depositary receipts, installment receipts and trust receipts are not eligible for inclusion in the Russell U.S. indices. Royalty trusts, U.S. limited liability companies, closed-end investment companies, blank-check companies, special-purpose acquisition companies, and limited partnerships are also not eligible for inclusion in the Russell U.S. indices. Business development companies, exchange traded funds and mutual funds are also excluded.

------

If an eligible company trades under multiple share classes, FTSE Russell will review each share class independently for U.S. index inclusion. Stocks must trade at or above $1.00 (on its primary exchange) on the rank day of each year to be eligible for inclusion during annual reconstitution. However, in order to reduce unnecessary turnover, if an existing index member's closing price is less than $1.00 on the rank day, it will be considered eligible if the average of the daily closing prices (from its primary exchange) during the 30 days prior to the rank day is equal to or greater than $1.00. If an existing index member does not trade on the rank day , it must price at $1.00 or above on another eligible U.S. exchange to remain eligible. A stock added during the quarterly IPO process is considered a new index addition and therefore must have a closing price on its primary exchange at or above $1.00 on the last day of the IPO eligibility period in order to qualify for index inclusion. Companies with a total market capitalization of less than $30 million are not eligible for inclusion in the Russell U.S. indices. Similarly, companies with only 5% or less of their shares available in the marketplace are not eligible for the Russell U.S. indices.

***Semi-annual Reconstitution***

Reconstitution is the process by which all Russell indices are completely rebuilt. Reconstitution is a vital part of the creation of a benchmark which accurately represents a particular market segment. Companies may get bigger or smaller over time, or periodically undergo changes in their style characteristics. Reconstitution ensures that the companies continue to be correctly represented in the appropriate Russell indices.

On the rank day, all eligible securities are ranked by their total market capitalization. The largest 4,000 become the Russell 3000E Index, and the other Russell U.S. indices are determined from that set of securities. If there are not 4,000 eligible securities in the U.S. market, the entire eligible set is included.

Reconstitution occurs on the fourth Friday in June and the second Friday in December. A full calendar for reconstitution is published each spring.

Eligible IPOs are added to the Russell U.S. indices quarterly to ensure that new additions to the institutional investing opportunity set are reflected in the representative indices. FTSE Russell focuses on IPOs each quarter because it is important to reflect market additions between reconstitution periods. Companies filing an IPO registration statement (or the local equivalent when outside the United States) and listing with the same quarter on an eligible U.S. exchange are reviewed for eligibility regardless of previous trading activity (exceptional or unique events may induce extraordinary treatment which will be communicated appropriately). Companies currently trading on foreign exchanges or OTC markets will be reviewed for eligibility if: (1) the company files an IPO statement for an eligible U.S. exchange; and (2) the offering is announced to the market and confirmed by FTSE Russell's vendors as an IPO.

***Capitalization Adjustments***

After membership is determined, a security's shares are adjusted to include only those shares available to the public, which is often referred to as "free float." The purpose of this adjustment is to exclude from market calculations the capitalization that is not available for purchase and is not part of the investable opportunity set. Stocks in the Russell U.S. indices are weighted by their available (also called "**float-adjusted**") market capitalization, which is calculated by multiplying the primary closing price by the available shares. Adjustments to shares are reviewed at reconstitution, during quarterly update cycles and for corporate actions such as mergers.

Certain types of shares are considered restricted and removed from total market capitalization to arrive at free float or available market capitalization, such as shares directly owned by state, regional, municipal and local governments (excluding shares held by independently managed pension schemes for governments), shares held by directors, senior executives and managers of the company, and by their family and direct relations, and by companies with which they are affiliated, and shares with high shareholding concentration, etc.

***Corporate Action-Driven Changes***

FTSE Russell defines a corporate action as an action on shareholders with a prescribed ex-date (e.g., rights issue, special dividend, stock split). The share price and indices in which the company is included will be subject to an adjustment on the ex-date. This is a mandatory event. FTSE Russell defines a corporate event as a reaction to company news (event) that might impact the index depending on the index rules. FTSE Russell applies corporate actions and events to its indices on a daily basis. Depending upon the time an action is determined to be final, FTSE Russell will either (1) apply the action before the open on the ex-date, or (2) apply the action providing appropriate notice, referred to as "delayed action."

------

For merger and spin-off transactions that are effective between the rank day and the business day immediately before the index lock down takes effect prior to the reconstitution, the market capitalizations of the impacted securities are recalculated and membership is reevaluated as of the effective date of the corporate action. For corporate events that occur during the reconstitution lock down period (which take effect from the open on the first day of the lock-down period onwards), market capitalizations and memberships will not be reevaluated. Non-index members that have been considered ineligible as of the rank day will not be reevaluated in the event of a subsequent corporate action that occurs between the rank day and the reconstitution effective date.

If a company distributes shares of an additional share class to its existing shareholders through a mandatory corporate action, FTSE Russell evaluates the additional share class for separate index membership. The new share class will be deemed eligible if the market capitalization of the distributed shares meets the minimum size requirement (above the minimum market capitalization breakpoint defined as the smallest member of the Russell 3000E Index from the previous rebalance, adjusted for performance to date.) Index membership of additional share classes that are added due to corporate actions will mirror that of the pricing vehicle, as will style and stability probabilities. If the distributed shares of an additional share class do not meet eligibility requirements, they will not be added to the index (the distributed shares may be added to the index temporarily until they are settled and listed to enable index replication).

"No Replacement" Rule: Securities that leave a Russell U.S. index for any reason (e.g., mergers, acquisitions or other similar corporate activities) are not replaced. Thus, the number of securities in a Russell U.S. index over the year will fluctuate according to corporate activity.

To maintain representativeness and maximize the available investment opportunity for index managers, the Russell U.S. indices are reviewed quarterly for updates to shares outstanding and to free floats used within the index calculation. The changes are implemented quarterly in March, June, September and December.

***License Agreement***

We and FTSE Russell have entered into a non-exclusive license agreement providing for the license to us, in exchange for a fee, of the right to use certain Russell U.S. indices in connection with the notes.

**The S&P<sup>®</sup>/ASX 200 Index**

The S&P<sup>®</sup>/ASX 200 Index (the "**AS51**") is designed to measure the performance of the 200 largest index-eligible stocks listed on the Australian Securities Exchange (the "**ASX**") by float-adjusted market capitalization. The AS51 was first launched in 1979 by the ASX and was acquired and re-launched by its current index sponsor on April 3, 2000. The AS51 is sponsored, calculated, published and disseminated by SPDJI. The AS51 is reported by Bloomberg under the ticker symbol "AS51."

***Index Composition***

The AS51 weights companies according to the GICS<sup>®</sup>, which creates uniform ground rules for replicable, custom-tailored, industry-focused portfolios. It also enables meaningful comparisons of sectors and industries across regions.

***Standards for Listing and Maintenance***

The S&P<sup>®</sup>/ASX Equity Indices Committee (for purposes of this section, the "**Index Committee**") aims to design a highly liquid and tradable index whose total market capitalization is large enough to approximate the market segment it is capturing while keeping the number of stocks at a minimum. Both market capitalization and liquidity are assessed using the previous six months' worth of data. Quarterly review changes take effect the third Friday of March, June, September and December.

The criteria for index additions include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;●*Listing*. Only securities listed on the ASX are considered for inclusion in the AS51;

&nbsp;&nbsp;&nbsp;&nbsp;●*Market Capitalization*. The market capitalization criterion for stock inclusion is based upon the daily average market capitalization of a security over the last three months. The stock price history (last three months, adjusted for price-adjusting corporate actions), latest available shares on issue, and the investable weight factor ("**IWF**") are the relevant variables for the calculation. The IWF is a variable that is primarily used to determine the available float of a security for ASX listed securities; and

&nbsp;&nbsp;&nbsp;&nbsp;●*Liquidity*. Only securities that are regularly traded are eligible for inclusion in the AS51. A stock's liquidity is measured relative to its peers. Relative Liquidity is calculated as follows:

<u> Relative Liquidity =</u> <u> Stock Median Liquidity </u> <br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Market Liquidity

Where:

oStock Median Liquidity is the median daily value traded for each stock divided by the average float/index weight-adjusted market capitalization for the previous three months; and

oMarket Liquidity is determined using the market capitalization weighted average of the stock median liquidities of the 500 companies in the All Ordinaries index, an index that includes nearly all ordinary shares listed on the ASX.

Stocks must have a minimum Relative Liquidity of 50% to be included in the AS51 and higher hierarchical indices. If any stock's Relative Liquidity drops below half of the 50% threshold, it becomes ineligible and is removed at the next rebalancing.

&nbsp;&nbsp;&nbsp;&nbsp;●*Eligible Securities.* Common and equity preferred stocks (which are not of a fixed income nature) must be classified by GICS. Hybrid stocks, such as convertible stock, bonds, warrants and preferred stock that provide a guaranteed fixed return, are not eligible. Listed investment companies (LICs) and listed investment trusts (LITs) that invest in a portfolio of securities are not eligible for index inclusion. Equity and mortgage REITs are eligible for inclusion.

& acquisitions activity are removed from the AS51 at the cash offer price for cash-only offers. Otherwise, the best available price in the market is used.

*Rebalancing.* Rebalancing of the AS51 series occurs on a regular basis. Both market capitalization and liquidity are assessed using the previous six months' worth of data to determine index eligibility. Shares and IWFs updates are also applied regularly. Rebalancing announcements are made on the first Friday of March, June, and December; therefore, a two-week notice period is provided before the rebalancing takes effect at these reviews. For the September rebalancing, the reference date used for the six months' worth of trading data is the second to last Friday of the month prior to the rebalancing.

The Index Committee may change the date of a given rebalancing for reasons including market holidays occurring on the scheduled rebalancing date. Any such change will be announced with proper advance notice where possible.

*Selection Buffers.* In order to limit the level of index turnover, the index applies selection buffers by rank for both additions and deletions. If a non-constituent ranks higher than the buffer for a specific index at a given review, the non-constituent is added to the index in place of the existing constituent. Similarly, if an index constituent falls outside the buffer rule, the constituent is removed from the index. Potential index inclusions and exclusions need to satisfy a buffer requirement in terms of the rank of the stock relative to the AS51. The following buffer aims to limit the level of index turnover that may take place at each quarterly rebalancing, maximizing the efficiency and limiting the cost associated with holding the index portfolio.

The Rank Buffer for addition to the AS51 is 179<sup>th</sup> or higher, and for deletion, 221<sup>st</sup> or lower.

This float-adjusted market capitalization rank buffer serves as the guideline used by the Index Committee to arrive at any potential constituent changes to the AS51. However, the Index Committee has complete discretion to by-pass these rules when circumstances warrant.

*Frequency.* The AS51 constituents are rebalanced quarterly to ensure adequate market capitalization and liquidity. Quarterly rebalancing changes take effect after the market close on the third Friday of March, June, September, and December.

*Share Updates.* The share count for all index constituents are updated quarterly and are rounded to the nearest thousand ('000). Share updates for foreign-domiciled securities will take place at each quarterly rebalancing. The update to the number of shares outstanding will only take place when the three-month average of CHESS Depository Interests or the Total Securities held in the Australian branch of issuer sponsored register (where supplied) and in the Clearing House Electronic Subregister System ("**CHESS**"), on the rebalancing reference date, differs from the current number of shares used by 5% or more.

***Index Calculation***

The AS51 is calculated using a base-weighted aggregate methodology so that the level of the AS51 reflects the total market value of all the component stocks relative to a particular base period. The total market value of a company is determined by multiplying the price of its stock by the number of shares available after float (IWF) adjustment. An indexed number is used to represent the result of this calculation in order to make the value easier to work with and track over time.

A stock's weight in the AS51 is determined by the float-adjusted market capitalization of the stock. The number of shares outstanding is reduced to exclude closely held shares from the index calculation because such shares are not available to investors. The AS51 calculates an IWF, which is the percentage of total shares outstanding that are included in the index. All constituents in the AS51 are assigned an IWF. A company must have a minimum IWF of 0.15 to be eligible for index inclusion, however an IWF at or above that level is not necessary for ongoing index membership.

On any given day, the index value is the quotient of the total available market capitalization of its constituents and its divisor. Continuity in the index value is maintained by adjusting the divisor for all changes in the constituents' share capital after the base date. This includes additions and deletions to the AS51, rights issues, share buybacks and issuances, spin-offs, and adjustments in availability. The divisor's time series is, in effect, a chronological summary of all changes affecting the base capital of the index. The divisor is adjusted such that the index value at an instant just prior to a change in base capital equals the index value at an instant immediately following that change. The divisor will be adjusted to account for new addition to or deletion from the AS51 and certain corporate actions, such as special cash dividend, certain stock dividend, rights offering, new share issuance, reduction of capital and merger.

------

***Index Governance***

The AS51 is maintained by the Index Committee. SPDJI chairs the Index Committee, which comprises five voting members representing both SPDJI and the ASX.

Decisions made by the Index Committee include all matters relating to index construction and maintenance. The Index Committee meets regularly to review market developments and convenes as needed to address major corporate actions. It is the sole responsibility of the Index Committee to decide on all matters relating to methodology, maintenance, constituent selection and index procedures. The Index Committee makes decisions based on all publicly available information and discussions are kept confidential to avoid any unnecessary impact on market trading.

***Index Eligibility***

For purposes of membership in the Select Industry Indices, SPDJI applies the inclusion and exclusion criteria separately. Membership is based on a company's GICS<sup>®</sup> classification, as well as liquidity and market cap requirements.

<u>Index Inclusion Criteria</u> 

To be eligible for inclusion in the Select Industry Indices, companies must be in the S&P TM Index, must be included in the relevant GICS<sup>®</sup> sub-industry (*e.g.* homebuilding) and must satisfy one of the two following combined size and liquidity criteria:

&nbsp;&nbsp;&nbsp;&nbsp;●have a float-adjusted market capitalization (as defined below) above U.S. $500 million and float-adjusted liquidity ratio (as defined below) above 90%; or

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;●have a float-adjusted market capitalization above U.S. $400 million and float-adjusted liquidity ratio above 150%.

Notwithstanding the foregoing, to be eligible for inclusion in the SPSIBK, a company's float-adjusted market capitalization must be above $2 billion and its float-adjusted liquidity ratio must be above 100%.

Some companies may have more than one share class line in the S&P TM Index. In the S&P Select Industry Indices, each company is represented once by the "Designated Listing", which is generally the share class with both the highest one-year trading liquidity and largest float-adjusted market capitalization.

All stocks satisfying the above requirements are included in a Select Industry Index. At each rebalancing, at least 35 stocks are selected for each Select Industry Index. In the event that fewer than 35 stocks are selected for each Select Industry Index using the eligible primary sub-industries (primary stocks), certain indices will select stocks for inclusion from a supplementary list of highly correlated sub-industries (supplementary stocks) based on process established by SPDJI. Additionally, minimum market capitalization requirements may be relaxed for all Select Industry Indices to ensure that there are at least 22 stocks in each Select Industry Index as of each rebalancing effective date.

<u>Index Exclusion Criteria</u> 

Existing index constituents are removed at the quarterly rebalancing effective date if either their float-adjusted market capitalization falls below U.S. $300 million or their float-adjusted liquidity ratio falls below 50%.

Notwithstanding the foregoing, existing index constituents of the SPSIBK are removed at the quarterly rebalancing date if either their float-adjusted market capitalization falls below $1 billion or their float-adjusted liquidity ratio falls below 50%.

<u>Eligibility Factors</u> 

*Market Capitalization.* The market capitalization measurement used is float-adjusted market capitalization. Under float adjustment, the share counts used in calculating the indices reflect only those shares available to investors rather than all of a company's outstanding shares. Float adjustment excludes shares that are closely held by control groups, other publicly traded companies, government agencies, or other long-term strategic shareholders.

*Liquidity.* The liquidity measurement used is a float-adjusted liquidity ratio, defined as the dollar value traded over the previous 12-months divided by the float-adjusted market capitalization as of the rebalancing reference date. The length of time to evaluate liquidity is reduced to the available trading period for IPOs or spin-offs that do not have 12 months of trading history. In these cases, the dollar value traded available as of the rebalancing reference date is annualized.

*Takeover Restrictions.* At the discretion of SPDJI, constituents with shareholder ownership restrictions defined in company bylaws may be deemed ineligible for inclusion in a Select Industry Index. Ownership restrictions preventing entities from replicating the index weight of a stock may be excluded from the eligible universe or removed from the applicable Select Industry Index. SPDJI will provide up to five days advance notification of a deletion between rebalancing due to ownership restrictions.

*Turnover.* SPDJI believes turnover in index membership should be avoided when possible. At times a stock may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to a Select Industry Index, not for continued membership. As a result, an index constituent that appears to violate criteria for addition to a Select Industry Index will not be deleted unless ongoing conditions warrant a change in the composition of the applicable Select Industry Index.

*Sector Classification.* A Select Industry Index includes companies in the applicable GICS<sup>®</sup> sub-industries set forth above.

***Select Sector Index Capping Methodology***

For reweighting purposes, the Select Sector Indices are rebalanced quarterly after the close of business on the third Friday of March, June, September and December using the following procedures:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.The rebalancing reference date is the second Friday of March, June, September and December. Closing prices as of the Wednesday prior to the second Friday of the rebalancing month are used for setting capped index weights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.With prices reflected on the rebalancing reference date, adjusted for any applicable corporate actions, and membership, shares outstanding and IWFs as of the rebalancing effective date, each company is weighted by float-adjusted market capitalization.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.If any company has a float-adjusted market capitalization weight greater than 24%, the company's weight is capped at 23%, which allows for a 2% buffer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.The sum of the companies with weights greater than 4.8% cannot exceed 50% of the total index weight. These caps are set to allow for a buffer below the 5% limit.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.If the rule in Step 4 is breached, set the weight of companies greater than 4.8% equal to:

𝑊𝑖<sup>𝐶𝑎𝑝𝑝𝑒𝑑</sup> = max <u>45% ×</u> <u>𝑊<sub>𝑖</sub></u> , 4.5%

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;∑<sup>𝑁</sup><sub>𝑖</sub> 𝑊<sub>𝑖</sub>

where:

N = total number of companies with index weights over 4.8%, after checking the single company cap

Wi = index weight of the N companies with individual company weights over 4.8%, after checking the single company cap

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.Proportionally redistribute the excess weight from Steps 3 to 5 to companies with an initial weight less than 4.8%, setting a 4.5% upper bound on the companies' index weight.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.Assign index share amounts to each constituent to arrive at the weights calculated above. Since index shares are assigned based on prices one week prior to rebalancing, the actual weight of each constituent at the rebalancing differs somewhat from these weights due to market movements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.If, on the second to last business day of March, June, September or December, a company has a weight greater than 24% or the sum of the companies with weights greater than 4.8% exceeds 50%, a secondary reweighting will be triggered with the effective date being after the close of the last business day of the

------

month. This secondary reweighting will use the closing prices as of the second to last business day of March, June, September or December, utilizing the current additional weight factors and membership, shares outstanding, and IWFs as of the rebalancing effective date.

When companies represented in the Select Sector Indices are represented by multiple share classes, maximum weight capping is based on company float-adjusted market capitalization, with the weight of multiple-class companies allocated proportionally to each share class based on its float-adjusted market capitalization as of the rebalancing reference date. If no capping is required, both share classes remain in the relevant Select Sector Index at their natural float-adjusted market capitalization.

***Index Calculation, Maintenance and Governance***

The Select Sector Indices are calculated, maintained and governed using the same methodology as the S&P 500<sup>®</sup> Index, subject to the capping methodology described above. For additional information about the calculation, maintenance and governance of the S&P 500<sup>®</sup> Index, see "—The S&P U.S. Indices" below.

The S&P 500<sup>®</sup> Index consists of stocks of 500 companies selected to provide a performance benchmark for the U.S. equity markets. The S&P 500<sup>®</sup> Index is reported by Bloomberg under the ticker symbol "SPX."

**The S&P MidCap 400<sup>®</sup> Index**

The S&P MidCap 400<sup>®</sup> Index consists of stocks of 400 companies selected to provide a performance benchmark for the medium market capitalization segment of the U.S. equity markets. The S&P MidCap 400<sup>®</sup> Index is reported by Bloomberg under the ticker symbol "MID."

**The S&P SmallCap 600<sup>®</sup> Index** 

The S&P SmallCap 600<sup>®</sup> Index consists of stocks of 600 companies selected to provide a performance benchmark for the small market capitalization segment in the U.S. equity markets. The S&P SmallCap 600<sup>®</sup> Index is reported by Bloomberg under the ticker symbol "SML."

***Composition of the S&P U.S. Indices***

Securities must meet the following eligibility factors to be considered eligible for inclusion in the S&P U.S. Indices. Constituent selection is at the discretion of the SPDJI's U.S. index committee (for purposes of this section, the "**Index Committee**") and is based on the eligibility criteria.

Changes to the S&P U.S. Indices are made as needed, with no scheduled reconstitution. Rather, changes in response to corporate actions and market developments can be made at any time. Constituent changes are typically announced two to five days before they are scheduled to be implemented.

Additions to the S&P U.S. Indices are evaluated based on the following eligibility criteria:

&nbsp;&nbsp;&nbsp;&nbsp;●*Domicile*. Only common stocks of U.S. companies are eligible. For index purposes, a U.S. company has the following characteristics:

■satisfies the periodic reporting obligations imposed by the U.S. Securities Exchange Act of 1934 by filing forms for domestic issuers, such as, but not limited to, Form 10-K annual reports, Form 10-Q quarterly reports, and Form 8-K current reports;

■the U.S. portion of fixed assets and revenues constitutes a plurality of the total, but need not exceed 50%. When these factors are in conflict, fixed assets determine plurality. Revenue determines plurality when there is incomplete asset information. Geographic information for revenue and fixed asset allocations are determined by the company as reported in its annual filings. If this criteria is not met or is ambiguous, SPDJI may still deem the company to be a U.S. company for index purposes if its primary listing, headquarters and incorporation are all in the United States and/or "a domicile of convenience" (Bermuda, Channel Islands, Gibraltar, islands in the Caribbean, Isle of Man, Luxembourg, Liberia or Panama); and

■the primary listing is on an eligible U.S. exchange.

In situations where the only factor suggesting that a company is not a U.S. company is its tax registration in a "domicile of convenience" or another location chosen for tax-related reasons, SPDJI normally determines that the company is still a U.S. company. The final determination of domicile eligibility is made by the Index Committee, which can

------

consider other factors including, but not limited to, operational headquarters location, ownership information, location of officers, directors and employees, investor perception and other factors deemed to be relevant.

&nbsp;&nbsp;&nbsp;&nbsp;●*Exchange Listing*. A primary listing on one of the following U.S. exchanges is required: NYSE, NYSE Arca, NYSE American, Nasdaq Global Select Market, Nasdaq Global Market, Nasdaq Capital Market, Cboe BZX, Cboe BYX, Cboe EDGA or Cboe EDGX exchanges.

&nbsp;&nbsp;&nbsp;&nbsp;●*Organizational Structure and Share Type*. Eligible organizational structures and share types are corporations (including equity and mortgage REITS) and common stock (i.e., shares). Ineligible organizational structures and share types include business development companies, limited partnerships, master limited partnerships, limited liability companies, closed-end funds, exchange-traded funds, exchange-traded notes, royalty trusts, special purpose acquisition companies, preferred and convertible preferred stock, unit trusts, equity warrants, convertible bonds, investment trusts, rights, American Depositary Receipts and tracking stocks. As of April 17, 2023, all companies with multiple share class structures are considered eligible candidates for the S&P Composite 1500 Indices.

&nbsp;&nbsp;&nbsp;&nbsp;●*Market Capitalization*. The unadjusted company market capitalization should be within a specified range. Such ranges are reviewed quarterly and updated as needed to ensure they reflect current market conditions. For spin-offs, S&P U.S. Index membership eligibility is determined using when-issued prices, if available.

&nbsp;&nbsp;&nbsp;&nbsp;●*Liquidity*. Using composite pricing and volume, the ratio of annual dollar value traded (defined as average closing price over the period multiplied by historical volume over the last 365 calendar days) to float-adjusted market capitalization should be at least 0.10, and the stock should trade a minimum of 250,000 shares in each of the six months leading up to the evaluation date.

&nbsp;&nbsp;&nbsp;&nbsp;●*IWF*. The IWF for each company represents the portion of the total shares outstanding that are considered part of the public float for purposes of the S&P U.S. Indices. An IWF of at least 0.10 is required.

&nbsp;&nbsp;&nbsp;&nbsp;●*Financial Viability.* The sum of the most recent four consecutive quarters' Generally Accepted Accounting Principles (GAAP) earnings (net income excluding discontinued operations) should be positive as should the most recent quarter. For REITs, financial viability is based on GAAP earnings and/or Funds From Operations, if reported.

&nbsp;&nbsp;&nbsp;&nbsp;●*Treatment of IPOs.* Initial public offerings should be traded on an eligible exchange for at least 12 months before being considered for addition to an S&P U.S. Index. Spin-offs or in-specie distributions from existing constituents do not need to be seasoned for 12 months prior to their inclusion in an S&P U.S. Index.

&nbsp;&nbsp;&nbsp;&nbsp;●*Sector Balance.* A company is evaluated for its contribution to sector balance maintenance, as measured by a comparison of each GICS<sup>®</sup> sector's weight in an index with its weight in the S&P U.S. Total Market Index, in the relevant market capitalization range. The S&P TM Index is a float-adjusted, market-capitalization weighted index designed to track the broad U.S. equity market, including large-, mid-, small- and micro-cap stocks.

SPDJI believes turnover in membership in the S&P U.S. Indices should be avoided when possible. At times a stock may appear to temporarily violate one or more of the addition criteria. However, the addition criteria are for addition to the S&P U.S. Indices, not for continued membership. As a result, a constituent of the S&P U.S. Indices that appears to violate criteria for addition to the S&P U.S. Indices is not deleted unless ongoing conditions warrant an index change.

***Calculation of the S&P U.S. Indices***

The S&P U.S. Indices are float-adjusted market capitalization-weighted indices. On any given day, the index value of each S&P U.S. Index is the total float-adjusted market capitalization of that S&P U.S. Index's constituents divided by its divisor. The float-adjusted market capitalization reflects the price of each stock in the relevant S&P U.S. Index multiplied by the number of shares used in the index value calculation.

*Float Adjustment.* Float adjustment means that the number of shares outstanding is reduced to exclude closely held shares from the calculation of the index value because such shares are not available to investors. The goal of float adjustment is to distinguish between strategic (control) shareholders, whose holdings depend on concerns such as maintaining control rather than shorter term economic fortunes of the company, and those holders whose investments depend on the stock's price and their evaluation of a company's future prospects. Generally, these "control holders"

------

include officers and directors, private equity, venture capital & special equity firms, asset managers and insurance companies with board of director representation, other publicly traded companies that hold shares for control, holders of restricted shares, company-sponsored employee share plans/trusts, defined contribution plans/savings and investment plans, foundations or family trusts associated with the company, holders of unlisted share classes of stock or government entities at all levels (other than government retirement/pension funds), sovereign wealth funds and any individual person who controls a 5% or greater stake in a company as reported in regulatory filings. Shares that are not considered outstanding are also not included in the available float. These generally include treasury stock, stock options, equity participation units, warrants, preferred stock, convertible stock and rights.

For each component, SPDJI calculates an IWF, which represents the portion of the total shares outstanding that are considered part of the public float for purposes of the relevant S&P U.S. Index.

*Divisor*. Continuity in the value of each S&P U.S. Index is maintained by adjusting its divisor for all changes in its constituents' share capital after its base date. This includes additions and deletions to the relevant S&P U.S. Index, rights issues, share buybacks and issuances and non-zero price spin-offs. The value of each S&P U.S. Index's divisor over time is, in effect, a chronological summary of all changes affecting the base capital of that S&P U.S. Index. The divisor of each S&P U.S. Index is adjusted such that the index value of that S&P U.S. Index at an instant just prior to a change in base capital equals the index value of that S&P U.S. Index at an instant immediately following that change.

The following types of corporate actions would require a divisor adjustment: company added/deleted, change in shares outstanding, change in IWF, special dividend and rights offering. Stock splits and stock dividends do not affect the divisor, because following a split or dividend, both the stock price and number of shares outstanding are adjusted by SPDJI so that there is no change in the market value of the relevant component. All stock split and dividend adjustments are made after the close of trading on the day before the ex-date.

***Maintenance of the S&P U.S. Indices***

Changes in response to corporate actions and market developments can be made at any time. Constituent changes are typically implemented with at least three business days advance notice.

*Removals.* Removals from the S&P U.S. Indices are evaluated based as follows:

&nbsp;&nbsp;&nbsp;&nbsp;●A company involved in a merger, acquisition or significant restructuring such that it no longer meets the eligibility criteria is deleted from the S&P U.S. Indices at a time announced by SPDJI, normally at the close of the last day of trading or expiration of a tender offer. Constituents that are halted from trading may be kept in the index until trading resumes, at the discretion of the Index Committee. If a stock is moved to pink sheets or any other OTC markets, the stock is removed.

&nbsp;&nbsp;&nbsp;&nbsp;●A company that substantially violates one or more of the eligibility criteria may be deleted at the Index Committee's discretion.

Any company that is removed from the S&P U.S. Indices must wait a minimum of one year from its index removal date before being reconsidered as a replacement candidate.

*Share Updates*. When total shares outstanding increase by at least 5%, but the new share issuance is to a strategic or major shareholder, it implies that there is no change in float-adjusted shares. However, in such instances, SPDJI will apply the share change and resulting IWF change regardless of whether the float change is greater than or equal to 5%. For companies with multiple share class lines, the 5% share change threshold is based on each individual multiple share class line rather than total company shares. Changes to share counts that are less than 5% of total shares are accumulated and made quarterly on the third Friday of March, June, September and December.

*IWF Updates*. Accelerated implementation for events less than $1 billion will include an adjustment to the company's IWF only to the extent that such an IWF change helps the new float share total mimic the shares available in the offering. To minimize unnecessary turnover, these IWF changes do not need to meet any minimum threshold requirement for implementation. Any IWF change resulting in an IWF of 0.96 or greater is rounded up to 1.00 at the next annual IWF review.

IWF changes will only be made at the quarterly review if the change represents at least 5% of total current shares outstanding and is related to a single corporate action that did not qualify for the accelerated implementation rule.

------

Quarterly share change events resulting from the conversion of derivative securities, acquisitions of private companies, or acquisitions of non-index companies that do not trade on a major exchange are considered to be available to investors unless there is explicit information stating that the new owner is a strategic holder.

Other than the situations described above, IWF changes are only made at the annual IWF review.

*Share/IWF Freezes*. A share/IWF freeze period is implemented during each quarterly rebalancing. The freeze period begins after the market close on the Tuesday preceding the second Friday of each rebalancing month (i.e. March, June, September and December) and ends after the market close on the third Friday of a rebalancing month. Pro-forma files are normally released after the market close on the second Friday, one week prior to the rebalancing effective date. In September, preliminary share and float data are released on the first Friday of the month. However, the share freeze period for September follows the same schedule as the other three quarterly share freeze periods. For illustration purposes, if rebalancing pro-forma files are scheduled to be released on Friday, March 5, the share/IWF freeze period will begin after the close of trading on Tuesday, March 9 and will end after the close of trading the following Friday, March 19 (i.e. the third Friday of the rebalancing month).

During the share/IWF freeze period, shares and IWFs are not changed except for certain corporate action events (such as merger activity, stock splits, and rights offerings), and the accelerated implementation rule is suspended. The suspension includes all changes that qualify for accelerated implementation and would typically be announced or effective during the share/IWF freeze period. At the end of the freeze period, all suspended changes will be announced on the third Friday of the rebalancing month and implemented five business days after the quarterly rebalancing effective date.

In general, companies that are the target of a cash M&A event that is expected to close by quarter end according to publicly available guidance may have their share count frozen at their current level for rebalancing purposes.

*Corporate Actions*. As specified in "—Calculation of the S&P U.S. Indices—Divisor" above, the divisor will be adjusted for certain corporate actions. Corporate actions (such as stock splits, stock dividends, non-zero price spin-offs and rights offerings) are applied after the close of trading on the day prior to the ex-date.

*Other Adjustments*. In cases where there is no achievable market price for a stock being deleted, it can be removed at a zero or minimal price at the Index Committee's discretion, in recognition of the constraints faced by investors in trading bankrupt or suspended stocks.

**The Swiss Market Index<sup>®</sup>**

The Swiss Market Index (the "**SMI**") is a price return float-adjusted market capitalization-weighted index of the 20 largest stocks traded on the SIX Swiss Exchange (the "**SSE**"). The SMI was first launched with a base level of 1,500 as of June 30, 1988. It is calculated, published and maintained by SIX Group Ltd., certain of its subsidiaries, and the management committee of the SSE (the "**Management Committee**") (collectively, for purposes of this section, the "**index sponsor**"). The SMI is reported by Bloomberg under the ticker symbol "SMI."

The Management Committee of the SSE is supported by an advisory board (the "**Index Commission**") in all index-related matters, notably in connection with changes to the index rules and adjustments, additions and exclusions outside of the established review and acceptance period. The Index Commission meets at least twice annually.

***Index Composition and Selection Criteria***

The SMI is designed to measure the performance of the blue-chip securities in the SSE. The 20 largest and most liquid equity securities traded at the SSE are selected as index components, which are weighted by their free float market capitalization. The weighting of each index component is capped at 18%.

Each year on the third Friday of September, the index composition is updated in the ordinary index review based on the selection list. With the cut-off dates on March 31, September 30 and December 31, a provisional selection list is created. It is the basis for the adjustment of extraordinary corporate actions.

*Component Selection Rules.* The index universe of the index is the Swiss Performance Index ("**SPI**"), which serves as a benchmark for the overall Swiss equity market. The component selection of the index is shown in the following table:

Index Number of Components Direct Selection Buffer <br> SMI 20 Rank 1-18 Rank 19-22

The 20 components of the index are selected from the selection list. To reduce fluctuations in the index, a buffer is applied for candidates ranked 19 to 22. The first 18 candidates are selected directly into the index. Out of the candidates ranked 19 to 22, current components are selected with priority over the other candidates. New components out of the buffer are selected until 20 components have been reached. Securities that are primary listed at more than one stock exchange and generate less than 50% of their total turnover at the SSE need to fulfill additional liquidity criteria in order to be selectable for the index. For this purpose, all the components of the SPI are ranked based on their cumulated on order book turnover over the past 12 months relative to the total turnover of the index universe. For this list, only turnovers of stock exchanges are considered where a security is primary listed. A security with several primary listings must rank amongst the first 18 components of the on order book turnover list in order to be selectable for the index. A security is excluded from the index once it ranks 23 or lower.

***Index Maintenance***

*Constituent Changes*. In the case of major market changes as a result of corporate action, the Management Committee of the SSE can decide at the request of the Index Commission that a security should be admitted to the index outside the ordinary index review period as long as it clearly fulfills the index selection rules. For the same reasons, a component can be excluded if the requirements for admission to the index are no longer fulfilled. As a general rule, extraordinary acceptances into the index take place after a three-month period on a quarterly basis after the close of trading on the third Friday of March, June, September and December (for example, a security listed on or before the fifth Trading Day prior to the end of November cannot be included until the following March). In case of a planned delisting, the exclusion of an index component is made, if possible, on the next ordinary index review date at the third Friday of March, June, September or December. However, if the delisting would be effective before the ordinary index review, the component is excluded from the index on the effective date of the delisting. If the index component no longer meets the criteria for remaining in the index due to a pending acquisition, it may be removed ahead of time. If a component is excluded from the index outside of the ordinary index review, it will be replaced by the best ranked candidate on the selection list which is not yet part of the index in order to maintain 20 components.

*Number of Shares and Free Float*. The reviewed number of shares and free float factors are communicated to the market with a review list. It presents the number of shares and the free float factor for each index component. It serves as the basis to calculate the free float market capitalization of an index component. The free float factor is a relative fraction multiplied with the number of shares in order to ensure that only share that are available for trading are considered in the index calculation. The free float factor is only calculated for shares with voting rights. Large stakes that reach or exceed the threshold of 5% and are held in firm hands are subtracted from the total market capitalization.

------

The following stakes are deemed to be held in firm hands:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●shareholding that have been acquired by one person or a group of persons who are subject to a shareholder or lockup agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●shareholding that have been acquired by one person or a group of persons who according to publicly known facts, have a long-term interest in a company.

Independent from the above, the stakes held by institutions of the following kinds are deemed free-floating:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●administrators

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●trustees

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●investment fund companies

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●pension funds

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;●investment companies

The SSE classifies at its own discretion persons and groups of persons who cannot be clearly assigned because of their area of activity or the absence of important information. Where an issuer has different categories of shares listed, these are considered separately for the free float calculation.

***Index Calculation***

The index sponsor calculates the SMI using the "Laspeyres formula," with a weighted arithmetic mean of a defined number of securities issues. The formula for calculating the index value can be expressed as follows:

<u> Index =</u> <u> Free Float Market Capitalization of the Index </u> <br> Divisor

The "free float market capitalization of the index" is equal to the sum of the product of the last-paid price, the number of shares, the free-float factor and, if a foreign stock is included, the current CHF exchange rate of all component stocks as of the time the index value is being calculated. The index value is calculated in real time and is updated whenever a trade is made in a component stock. Where any index component stock price is unavailable on any trading day, the index sponsor will use the last reported price for such component stock. Only prices from the SSE's electronic order book are used in calculating the SMI.

The divisor is a technical number used to calculate the SMI and is adjusted to reflect changes in market capitalization due to corporate events, and is adjusted by the index sponsor to reflect corporate events, as described in the index rules.

***License Agreement***

CIBC has entered into a non-exclusive license agreement providing for the license to it, in exchange for a fee, of the right to use indices owned and published by the index sponsor in connection with some products, including the notes.

SSE and its licensors (the "**Licensors**") have no relationship to us, other than the licensing of the SMI and the related trademarks for use in connection with the notes.

SSE and its Licensors do not sponsor, endorse, sell or promote the notes; recommend that any person invest in the notes; have any responsibility or liability for or make any decisions about the timing, amount or pricing of the notes; have any responsibility or liability for the administration, management or marketing of the notes; or consider the needs of the notes or the owners of the notes in determining, composing or calculating the SMI or have any obligation to do so.

SSE and its Licensors will not have any liability in connection with the notes. Specifically, SSE and its Licensors do not make any warranty, express or implied and disclaim any and all warranty about: the results to be obtained by the notes, the owners of the notes or any other person in connection with the use of the SMI and the data included in the SMI; the accuracy or completeness of the SMI and its data; and the merchantability and the fitness for a particular purpose or use of the SMI and its data. SSE and its Licensors will have no liability for any errors, omissions or interruptions in the SMI or its data. Under no circumstances will SSE or its Licensors be liable for any lost profits or indirect, punitive, special or consequential damages or losses, even if SSE or its Licensors knows that they might occur. The licensing agreement between us and SSE will be solely for our benefit and the benefit of SSE and not for the benefit of the owners of the notes or any other third parties.

**The TOPIX<sup>®</sup> Index** 

The Tokyo Stock Price Index (the "**TPX**"), also known as the TOPIX<sup>®</sup> Index, is a capitalization-weighted index of all companies listed on the TSE Prime Market. The TPX is developed, calculated, published and maintained by the JPXI. Publication of the TPX began on July 1, 1969, based on an initial index value of 100 at January 4, 1968. The TPX is reported by Bloomberg under the ticker symbol "TPX."

**Index Composition and Maintenance** 

The component stocks of the TPX consist of all Japanese common stocks listed on the TSE Prime Market. The TPX measures changes in the aggregate market value of these stocks. Japanese stocks admitted to the TSE are assigned to one of the Prime Market, the Standard Market or Growth Market (in principle). Stocks listed on the TSE Prime Market are limited to companies which have appropriate levels of market capitalization (liquidity) to be investment instruments for many institutional investors, maintain a higher quality of corporate governance, and commit to sustainable growth and improvement of medium- to long-term corporate value, putting constructive dialogue with investors at the center. Stocks listed on the Standard Market are typically companies which have appropriate levels of market capitalization (liquidity) to be investment instruments in the open market, maintain a basic level of corporate governance expected of listed companies, and commit to sustainable growth and improvement of medium- to long-term corporate value. The Growth Market is limited to companies which have a certain level of market value by disclosing business plans for realizing high growth potential and their progress towards these appropriately and in a timely manner, but at the same time pose a relatively high investment risk from the perspective of business track record.

The TPX is a free-float adjusted market capitalization-weighted index, with the market price of each component stock multiplied by the number of shares listed (as adjusted by multiplying the free-float weight ("**FFW**") to take into account only the listed shares deemed to be available for trading in the market). The JPXI is responsible for calculating and maintaining the TPX, and can add, delete or substitute the stocks underlying the TPX or make other methodological changes that could change the value of the TPX. The underlying stocks may be removed, if necessary, in accordance with deletion/addition rules which provide generally for the deletion of a stock from the TPX if such stock ceases to meet the criteria for inclusion. Stocks listed on the Standard Market or Growth Market of the TSE may be transferred to the Prime Market if they satisfy applicable criteria. Such criteria include numerical minimum values for number of shares listed, number of shareholders and average monthly trading volume, among others. Similarly, when a Prime Market stock falls within the coverage of TSE rules prescribing reassignment thereof to the Standard Market, such stock will be removed from the Prime Market.

Additions to the component stocks can occur (1) through the initial listing of a company (directly or via another stock exchange), with such changes taking effect on the last business day of the month after such initial listing; (2) as a result of changes in listing from the Standard Market or from the Growth Market to the Prime Market, with such changes taking effect on the transfer date, as applicable; or (3) through the initial listing of a new company resulting from a corporate consolidation, with such changes taking effect on the new listing date.

Deletions of constituents are conducted due to (1) de-listing, resulting from a corporate consolidation, when the surviving company re-lists with the TSE, with such changes taking effect on the initial listing date of the new company (normally two business days after the delisting date); (2) de-listing of a company for reasons other than those stated above, with such changes taking effect on the de-listing date; (3) designation of stocks to be de-listed, with such changes taking effect four business days after such designation; or (4) changes in listing from the Prime Market to the Standard Market, with such changes taking effect on the date of such change.

**Index Calculation** 

The TPX is not expressed in Japanese yen, but is presented in terms of points (as a decimal figure), rounded to the nearest one-hundredth. The TPX is calculated by multiplying 100 by the figure obtained by dividing the current free-float adjusted market value (the current market price per share at the time of the index calculation multiplied by the number of free-float adjusted common shares listed on the Prime Market at the same instance) (as adjusted by multiplying the FFW) (the "**Current Market Value**") by the base market value (*i.e.*, the Current Market Value on the base date) (the "**Base Market Value**").

------

The calculation of the TPX can be represented by the following formula:

Index = <u>Current Market Value</u> × 100 <br> &nbsp;&nbsp;&nbsp;&nbsp;Base Market Value

In order to maintain continuity, the Base Market Value is adjusted from time to time to ensure that it reflects only price movements resulting from auction market activity, and to eliminate the effects of other factors and prevent any instantaneous change or discontinuity in the level of the TPX. Such factors include, without limitation: new listings, delistings, new share issues either through public offerings or through rights offerings to shareholders (limited to cases where the allotted subscription warrant securities are listed), issuance of shares as a consequence of exercise of convertible bonds or warrants, and transfer of listed securities from the Prime Market to the Standard Market of the TSE.

The formula for the adjustment is as follows:

---

| | | |
|:---|:---|:---|
| Free-float adjusted Market Value on business day before adjustment date | = | (Free-float adjusted Market Value on business day before adjustment date ± Adjustment Amount) |
| Base Market Value before adjustment |  | Base Market Value after adjustment |

---

Where Adjustment Amount is equal to the changes in the number of shares included in the calculation of the TPX *multiplied* by the price of those shares used for the purposes of the adjustment.

Therefore,

---

| | | |
|:---|:---|:---|
| New Base Market Value | = | Old Base Market Value × (Free-float adjusted Market Value on business day before adjustment date ± Adjustment Amount) |
| New Base Market Value | = | Free-float adjusted Market Value on business day before adjustment date |

---

The Base Market Value remains at the new value until a further adjustment is necessary as a result of another change. As a result of such change affecting the Current Market Value or any stock underlying the TPX, the Base Market Value is adjusted in such a way that the new value of the TPX will equal the level of the TPX immediately prior to such change.

No adjustment is made to the Base Market Value, however, in the case of events such as stock splits or decreases in capital without compensation, which theoretically do not affect market capitalization.

**License Agreement**

CIBC will enter into an agreement with TSE or its affiliates as necessary to provide us and certain of our affiliates or subsidiaries, in exchange for a fee, a non-exclusive license to use TPX, which is sponsored, calculated and published by TSE, in connection with certain securities, including the notes.

TPX Value and TPX Marks are subject to the proprietary rights owned by TSE and TSE owns all rights and know-how relating to the TPX such as calculation, publication and use of TPX Value and relating to TPX Marks. TSE shall reserve the rights to change the methods of calculation or publication, to cease the calculation or publication of TPX Value or to change TPX Marks or cease the use thereof. TSE makes no warranty or representation whatsoever, either as to the results stemmed from the use of TPX Value and TPX Marks or as to the figure at which TPX Value stands on any particular day. TSE gives no assurance regarding accuracy or completeness of TPX Value and data contained therein. Further, TSE shall not be liable for the miscalculation, incorrect publication, delayed or interrupted publication of TPX Value. No notes are in any way sponsored, endorsed or promoted by the TSE. TSE shall not bear any obligation to give an explanation of the notes or any advice on investments to any purchaser of the notes or to the public. TSE neither selects specific stocks or groups thereof nor takes into account any needs of the issuing company or any purchaser of the notes, for calculation of TPX Value. Including but not limited to the foregoing, the TSE shall not be responsible for any damage resulting from the issue and sale of the notes.

**CERTAIN TERMS OF THE NOTES**

**General**

Each issue of the notes will be part of a series of medium-term notes entitled "Senior Global Medium-Term Notes" that will be issued under the indenture, as amended and supplemented from time to time. The indenture is described more fully in the accompanying prospectus supplement and prospectus. The following description of the notes supplements and, to the extent it is inconsistent with, supersedes the description of the general terms and provisions of the notes and debt securities set forth under the headings "Description of the Notes We May Offer" in the accompanying prospectus supplement and "Description of Senior Debt Securities" in the accompanying prospectus. These documents should be read in connection with this document and the applicable pricing supplement.

The notes will be payable only in U.S. dollars. The notes are not subject to any sinking fund. The notes are not subject to the defeasance provisions described under "Description of Senior Debt Securities—Defeasance" in the accompanying prospectus.

We will issue the notes in the form of a fully registered global note registered in the name of the nominee of The Depository Trust Company ("**DTC**"). Beneficial interests in the notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Except in the limited circumstances described in the accompanying prospectus supplement, owners of beneficial interests in the notes will not be entitled to have the notes registered in their names, will not receive or be entitled to receive the notes in definitive form and will not be considered holders of the notes under the indenture.

**Interest Payment Dates, Coupon Payment Dates, Call Payment Dates and Maturity Date**

If (1) a day on which a fixed or floating interest payment is scheduled to be made (an "**Interest Payment Date**"), (2) a day on which a contingent coupon payment is scheduled to be made (a "**Coupon Payment Date**"), (3) a day on which payment is to be made if the notes are called (a "**Call Payment Date**"), or (4) the maturity date stated in the applicable pricing supplement, in each case, is not a Business Day (as defined below), the amounts payable will be paid on the next following Business Day and no interest will be paid in respect of such postponement. The calculation agent may postpone (i) a scheduled date on which the coupon due is determined (a "**Coupon Determination Date**"), and therefore the related Coupon Payment Date; (ii) a scheduled date on which it is determined if the notes will be called (a "**Call Observation Date**"), and therefore the related Call Payment Date; or (iii) the scheduled Final Valuation Date, and therefore the maturity date, in each case if any such date is not a Trading Day or a Market Disruption Event occurs or is continuing on such date. We describe the effect of Market Disruption Events under "—Valuation Dates" and "—Market Disruption Events" below.

**Observation Periods**

***For Notes Where the Reference Asset Is a Single Index:***

If any date during a period in which the Index is observed either continuously or at market close for the occurrence of a knock-out or other event (an "**Observation Period**") is not a Trading Day, such date will be excluded from the Observation Period. If a Market Disruption Event exists on any date during an Observation Period (other than a Valuation Date), then such date will be excluded from the Observation Period, unless a Market Disruption Event exists or continues for five or more consecutive scheduled Trading Days during an Observation Period, in which case such fifth consecutive day and each following day in the Observation Period until the occurrence of a Trading Day without a Market Disruption Event will nonetheless be part of the Observation Period and the calculation agent will determine, in its discretion, the index level by means of the formula for and method of calculating the Index which applied just prior to the Market Disruption Event, using the traded or quoted price on the primary exchange or market of each security included in the Index (or if an event giving rise to a Market Disruption Event has occurred with respect to a security included in the Index and is continuing on that fifth or later scheduled Trading Day, the calculation agent's good faith estimate of the price for that security). If a Valuation Date that is part of an originally scheduled Observation Period is postponed, then the Observation Period will be extended to include such Valuation Date as postponed.

***For Notes Where the Reference Asset Consists of Multiple Indices:***

If any date during an Observation Period is not a Trading Day for any Index, such date will be excluded from the Observation Period for that Index. If a Market Disruption Event exists on any date during an Observation Period (other than a Valuation Date) for an Index, then such date will be excluded from the Observation Period for such Index, unless a Market Disruption Event exists or continues for five or more consecutive scheduled Trading Days during an

------

Observation Period, in which case such fifth consecutive day and each following day in the Observation Period until the occurrence of a Trading Day without a Market Disruption Event will nonetheless be part of the Observation Period for that Index and the calculation agent will determine, in its discretion, the index level by means of the formula for and method of calculating the Index which applied just prior to the Market Disruption Event, using the traded or quoted price on the primary exchange or market of each security included in the Index (or if an event giving rise to a Market Disruption Event has occurred with respect to a security included in the Index and is continuing on that fifth or later scheduled Trading Day, the calculation agent's good faith estimate of the price for that security). For each Index that makes up the Reference Asset, the calculation agent will determine whether a Market Disruption Event exists with respect to each Index independent from other Indices. Therefore, a Market Disruption Event may exist for certain Indices and not exist for other Indices. If a Valuation Date that is part of an originally scheduled Observation Period is postponed for an Index, then the Observation Period for such Index will be extended to include such Valuation Date as postponed. If no Market Disruption Event exists with respect to an Index on the originally scheduled Valuation Date, the Observation Period for such Index will not be extended, irrespective of the existence of a Market Disruption Event with respect to any other Indices on the originally scheduled Valuation Date.

**Valuation Dates**

Unless otherwise specified in the applicable pricing supplement, the payment on the notes is calculated based on the value of the Reference Asset on the Coupon Determination Dates, Call Observation Dates, or one or more other dates during the term of the notes (each such date a "Valuation Date," and the last of such dates, or if there is only one such date, the "**Final Valuation Date**").

***For Notes Where the Reference Asset Is a Single Index:***

If a Valuation Date as set forth in the applicable pricing supplement is not a Trading Day, then such Valuation Date will be the next succeeding day that is a Trading Day. If a Market Disruption Event exists on a Valuation Date, then such Valuation Date will be the next Trading Day on which there is no Market Disruption Event. If a Market Disruption Event exists or continues for five consecutive scheduled Trading Days, then such fifth scheduled Trading Day will nonetheless be the Valuation Date, and the calculation agent will determine, in its discretion, the index level by means of the formula for and method of calculating the Index which applied just prior to the Market Disruption Event, using the traded or quoted price on the primary exchange or market of each security included in the Index (or if an event giving rise to a Market Disruption Event has occurred with respect to a security included in the Index and is continuing on that fifth scheduled Trading Day, the calculation agent's good faith estimate of the price for that security).

Unless otherwise specified in the applicable pricing supplement, if the payment on the notes is calculated based on the Closing Levels of an Index on certain consecutive scheduled Trading Days (a "**Valuation Period**"), and if (i) a Market Disruption Event occurs on a scheduled Valuation Date or (ii) any scheduled Valuation Date is determined by the calculation agent not to be a Trading Day (any such day in either (i) or (ii) being a "**non-Valuation Date**"), the Closing Level of the Index for the applicable non-Valuation Date will be the Closing Level of the Index on the next Valuation Date that occurs during the Valuation Period. For example, if the first and second scheduled Valuation Dates during the Valuation Period are non-Valuation Dates, then the Closing Level of the Index on the third scheduled Valuation Date will also be the Closing Level of the Index on the first and second scheduled Valuation Dates during the Valuation Period. If no further Valuation Dates occur after a non-Valuation Date, or if every scheduled Valuation Date after that non-Valuation Date is also a non-Valuation Date, then the Closing Level of the Index for that non-Valuation Date and each following non-Valuation Date, if any (or for all the scheduled Valuation Dates during the Valuation Period, if applicable), will be determined by the calculation agent, in its discretion, by means of the formula for and method of calculating the Index which applied just prior to the Market Disruption Event, using the traded or quoted price on the primary exchange or market of each security included in the Index (or if an event giving rise to a Market Disruption Event has occurred with respect to a security included in the Index on any such date, the calculation agent's good faith estimate of the price for that security).

For the avoidance of doubt, if Valuation Dates are scheduled to be within certain consecutive scheduled Trading Days, a Market Disruption Event on the first such scheduled Valuation Date could cause a Market Disruption Event to occur on one or more Valuation Dates simultaneously. If a Coupon Determination Date, Call Observation Date or Final Valuation Date is postponed, then the related Coupon Payment Date, Call Payment Date or maturity date will also be postponed by the same number of Business Days and no interest will be paid in respect of such postponement.

------

***For Notes Where the Reference Asset Consists of Multiple Indices:***

If a Valuation Date as set forth in the applicable pricing supplement is not a Trading Day for an Index, then such Valuation Date for such Index will be the next succeeding day that is a Trading Day for such Index. If a Market Disruption Event exists on a Valuation Date for an Index, then such Valuation Date for such Index will be the next Trading Day on which there is no Market Disruption Event for that Index. If a Market Disruption Event exists or continues for five consecutive scheduled Trading Days, then that fifth scheduled Trading Day will nonetheless be the Valuation Date for such Index, and the calculation agent will determine, in its discretion, the index level of such Index by means of the formula for and method of calculating such Index which applied just prior to the Market Disruption Event, using the traded or quoted price on the primary exchange or market of each security included in such Index (or if an event giving rise to a Market Disruption Event has occurred with respect to a security included in such Index and is continuing on that fifth scheduled Trading Day, the calculation agent's good faith estimate of the price for that security).

If the payment on the notes is calculated based on the Closing Levels of the Indices during a Valuation Period, the Closing Level of each Index will be determined as described in the second paragraph of "—Valuation Dates—For Notes Where the Reference Asset Is a Single Index" above.

For each Index that makes up the Reference Asset, the calculation agent will determine whether a Market Disruption Event exists on a Valuation Date with respect to each Index independent from other Indices. Therefore, a Market Disruption Event may exist for certain Indices and not exist for other Indices. If no Market Disruption Event exists with respect to an Index on an originally scheduled Valuation Date, the Closing Level of such Index as of that Valuation Date will be its Closing Level on that Valuation Date, irrespective of the existence of a Market Disruption Event with respect to any other Indices on that Valuation Date.

If a Coupon Determination Date, Call Observation Date or Final Valuation Date is postponed, then the related Coupon Payment Date, Call Payment Date or maturity date will also be postponed by the same number of Business Days and no interest will be paid in respect of such postponement.

**Market Disruption Events**

As to any Index, unless otherwise specified in the applicable pricing supplement, a "**Market Disruption Event**" means any of the following events, as determined by the calculation agent in its sole discretion:

(A)the suspension of or material limitation on trading, in each case, for more than two consecutive hours of trading, or during the one-half hour period preceding the close of trading, on the primary exchange where the securities included in an Index trade (without taking into account any extended or after-hours trading session), in 20% or more of the securities which then compose the Index or any Successor Index;

(B)the suspension of or material limitation on trading, in each case, for more than two consecutive hours of trading, or during the one-half hour period preceding the close of trading, on the primary exchange that trades options contracts or futures contracts related to the Index (without taking into account any extended or after-hours trading session), whether by reason of movements in price otherwise exceeding levels permitted by the relevant exchange or otherwise, in options contracts or futures contracts related to the Index, or any Successor Index; and

(C)in any other event, if the calculation agent determines that the event materially interferes with our ability or the ability of any of our affiliates to maintain or unwind all or a material portion of a hedge with respect to the notes that we or our affiliates have effected or may effect as described under "Use of Proceeds and Hedging" above.

For the purpose of determining whether a Market Disruption Event has occurred:

(1)a limitation on the hours in a Trading Day and/or number of days of trading will not constitute a Market Disruption Event if it results from an announced change in the regular business hours of the relevant exchange;

(2)a decision to permanently discontinue trading in the relevant futures or options contracts related to the Index, or any Successor Index, will not constitute a Market Disruption Event;

(3)a suspension in trading in a futures or options contract on the Index, or any Successor Index, by a major securities market by reason of (a) a price change violating limits set by that securities market, (b) an

------

imbalance of orders relating to those contracts, or (c) a disparity in bid and ask quotes relating to those contracts will constitute a suspension of or material limitation on trading in futures or options contracts related to the Index;

(4)a suspension of or material limitation on trading on the relevant exchange will not include any time when that exchange is closed for trading under ordinary circumstances; and

(5)if applicable to indices with component securities listed on the NYSE, for the purpose of clause (A) above, any limitations on trading during significant market fluctuations under NYSE Rule 80B, or any applicable rule or regulation enacted or promulgated by the NYSE or any other self-regulatory organization or the SEC of similar scope as determined by the calculation agent, will be considered "material."

**Adjustments to an Index**

If at any time an Index Sponsor makes a material change in the formula for or the method of calculating the relevant Index, or in any other way materially modifies the Index (other than a modification prescribed in that formula or method to maintain the Index in the event of changes in constituent stock and capitalization and other routine events), then, from and after that time, the calculation agent will, at the close of business in New York, New York, on each date that the level of the Index is to be calculated, calculate a substitute level of the Index in accordance with the formula for and method of calculating the Index last in effect prior to the change, but using only those securities that comprised the Index immediately prior to that change. Accordingly, if the method of calculating the Index is modified so that the level of the Index is a fraction or a multiple of what it would have been if it had not been modified, then the calculation agent will adjust the Index in order to arrive at a level of the Index as if it had not been modified.

Notwithstanding the above, the material modification of an Index may adversely affect the level of the Index and consequently, the return on the notes.

**Discontinuance of an Index**

If an Index Sponsor discontinues publication of the relevant Index, and the Index Sponsor or another entity publishes a successor or substitute equity index that the calculation agent determines, in its sole discretion, to be comparable to the Index (a "**Successor Index**"), then, upon the calculation agent's notification of that determination to the trustee and the Bank, that Successor Index will be deemed to be that Index for all purposes relating to the notes, including for purposes of determining whether a Market Disruption Event exists. Upon any selection by the calculation agent of a Successor Index, the Bank will cause notice to be given to the holders of the notes.

In the event that the Index Sponsor discontinues publication of an Index prior to maturity, and the calculation agent determines that no Successor Index is available, then, from and after that time, the calculation agent will, at the close of business in New York, New York, on each date that the level of the Index is to be calculated, calculate a substitute level of the Index in accordance with the formula for and method of calculating the Index last in effect prior to the discontinuance, but using only those securities that comprised the Index immediately prior to the discontinuance. If the calculation agent calculates a level as a substitute for the Index, the Index will still be the Reference Asset for all purposes, including the purpose of determining whether a Market Disruption Event exists, but all determinations should be made based on those securities that comprised the Index immediately prior to the discontinuance.

If on any date that the level of an Index is to be calculated, the Index Sponsor fails to calculate and announce the level of the Index, the calculation agent will calculate a substitute Closing Level of the Index in accordance with the formula for and method of calculating the Index last in effect prior to the failure, but using only those securities that comprised the Index immediately prior to that failure; *provided* that, if a Market Disruption Event occurs or is continuing on such day, then the provisions set forth herein under "—Market Disruption Events," "—Observation Periods" and "—Valuation Dates" shall apply in lieu of the foregoing.

Notwithstanding these alternative arrangements, discontinuance of the publication of, or the failure by the Index Sponsor to calculate and announce the level of, an Index may adversely affect the level of the Index and consequently, the return on the notes.

**Certain Definitions**

***Business Day***

A "Business Day" means a Monday, Tuesday, Wednesday, Thursday or Friday that is neither a legal holiday nor a day on which banking institutions are authorized or required by law or regulation to close in New York, New York.

------

***Closing Level***

The Closing Level of an Index (or a Successor Index) on any Trading Day will be its closing level on such Trading Day, as determined by the calculation agent based upon the level displayed on the applicable Bloomberg page, as specified in the applicable pricing supplement, or on any successor page on the Bloomberg or any successor service, as applicable.

***Record Date***

Any interest or coupon will be payable to the persons in whose names the notes are registered at the close of business on the Business Day immediately preceding the related Interest Payment Date or Coupon Payment Date (the "**Regular Record Date**"), and the final interest or coupon payable at maturity or upon an early redemption, as applicable, will be payable to the persons in whose names the notes are registered on the maturity date or the Call Payment Date, as applicable. For the purpose of determining the holder at the close of business on a Regular Record Date when business is not being conducted, the close of business will mean 5:00 P.M., New York City time, on that day.

***Trading Day***

Unless otherwise set forth in the applicable pricing supplement, a Trading Day with respect to an Index other than the MSCI EAFE<sup>®</sup> Index, the MSCI Emerging Markets Index or the EURO STOXX 50<sup>®</sup> Index means a day on which (i) the respective primary exchanges or markets for all of the securities included in the Index are open for trading, and (ii) the Index is calculated and published by its Index Sponsor. Although an Index Sponsor may publish a level with respect to the applicable Index on a day when one or more of the primary exchanges or markets for those constituent securities are closed, that day would not be a Trading Day for purposes of the applicable Index.

A Trading Day with respect to the MSCI EAFE<sup>®</sup> Index, the MSCI Emerging Markets Index or the EURO STOXX 50<sup>®</sup> Index means a day on which the relevant Index is calculated and published by its Index Sponsor, unless otherwise set forth in the applicable pricing supplement. Therefore, in the case of any such Index, a day would be a Trading Day with respect to that Index regardless of whether one or more of the primary exchanges or markets for the securities included in that Index is closed on that day, if the Index Sponsor publishes the level of that Index on that day.

**Role of the Calculation Agent**

The calculation agent has the sole discretion to make all determinations regarding the notes as described in this underlying supplement. Absent manifest error, all determinations of the calculation agent will be conclusive for all purposes and final and binding on you and us, without any liability on the part of the calculation agent.

We are expected to act as the calculation agent for each issue of the notes. However, we may change the calculation agent at any time without notifying you. The identity of the calculation agent will be set forth in the applicable pricing supplement.

**Same-Day Settlement and Payment**

The notes will be delivered in book-entry form only through DTC against payment by purchasers of the notes in immediately available funds. We will pay the payments on the notes in immediately available funds so long as the notes are maintained in book-entry form.

**Events of Default and Acceleration**

If the notes have become immediately due and payable following an Event of Default (as defined under "Description of Senior Debt Securities—Events of Default" in the accompanying prospectus) with respect to the notes, the default amount payable will be equal to the payment at maturity described in the applicable pricing supplement, calculated as though the date of acceleration were the maturity date and the Final Valuation Date were the fifth scheduled Trading Day prior to the maturity date, as accelerated. In addition, if the notes pay interest, you will receive interest accrued on the notes until the date that the required amount is paid.

If the notes have become immediately due and payable following an Event of Default, you will not be entitled to any additional payments with respect to the notes. For more information, see "Description of Senior Debt Securities—Events of Default" in the accompanying prospectus.

------

**Defeasance**

The defeasance described under "Description of Senior Debt Securities—Defeasance" in the accompanying prospectus will not be applicable to the notes offered hereby.

**Listing**

Unless otherwise specified in the applicable pricing supplement, the notes will not be listed on a securities exchange.

------

**THE BANK'S ESTIMATED VALUE OF THE NOTES**

The Bank's initial estimated value of the notes that will be set forth on the cover of the applicable pricing supplement will be equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the notes, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the notes. The Bank's initial estimated value does not represent a minimum price at which an agent or any other person would be willing to buy your notes in any secondary market (if any exists) at any time. The internal funding rate used in the determination of the Bank's initial estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. For additional information, see "Risk Factors—The Bank's initial estimated value of the notes will not be determined by reference to credit spreads for our conventional fixed-rate debt" above. The value of the derivative or derivatives underlying the economic terms of the notes is derived from the Bank's or a third party hedge provider's internal pricing models. These models are dependent on inputs such as the traded market prices of comparable derivative instruments and on various other inputs, some of which are market-observable, and which can include volatility, dividend rates, interest rates and other factors, as well as assumptions about future market events and/or environments. Accordingly, the Bank's initial estimated value of the notes will be determined when the terms of the notes are set based on market conditions and other relevant factors and assumptions existing at that time. See "Risk Factors—The Bank's initial estimated value does not represent future values of the notes and may differ from others' estimates" above.

The Bank's initial estimated value of the notes will be lower than the initial issue price of the notes because costs associated with selling, structuring and hedging the notes are included in the initial issue price of the notes. These costs include the selling commissions paid to the agents and other affiliated or unaffiliated dealers, the projected profits that our hedge counterparties, which may include our affiliates, expect to realize for assuming risks inherent in hedging our obligations under the notes and the estimated cost of hedging our obligations under the notes. Because hedging our obligations entails risk and may be influenced by market forces beyond our control, this hedging may result in a profit that is more or less than expected, or it may result in a loss. We or one or more of our affiliates will retain any profits realized in hedging our obligations under the notes. See "Risk Factors—The Bank's initial estimated value of the notes will be lower than the initial issue price (price to public) of the notes" above.

**MATERIAL CANADIAN FEDERAL INCOME TAX CONSEQUENCES**

An investor should read carefully the description of material Canadian federal income tax considerations relevant to a Non-Resident Holder (as defined therein) owning debt securities under "Material Income Tax Consequences—Canadian Taxation" in the accompanying prospectus. Canadian federal income tax considerations applicable to the notes may be described particularly when such notes are offered in the applicable pricing supplement related thereto and, in that event, the disclosure in the accompanying prospectus will be superseded by the disclosure in such pricing supplement to the extent indicated therein.

**MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES**

The following summary of the material U.S. federal income tax considerations of the acquisition, ownership, and disposition of the notes is based upon the Internal Revenue Code of 1986, as amended (the "Code"), regulations promulgated under the Code by the U.S. Treasury Department ("Treasury") (including proposed and temporary regulations), rulings, current administrative interpretations and official pronouncements of the IRS, and judicial decisions, all as currently in effect and all of which are subject to differing interpretations or to change, possibly with retroactive effect. The following discussion supplements, and to the extent inconsistent supersedes, the discussion under "Material Income Tax Consequences—United States Taxation" in the accompanying prospectus and is not exhaustive of all possible tax considerations. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences described below. This summary does not include any description of the tax laws of any state or local governments, or of any foreign government, that may be applicable to a particular holder. If the tax consequences associated with the notes are different than those described below, they will be described in the applicable pricing supplement.

The following disclosure has been prepared without regard to any particular note that holders may purchase in the future and, therefore, is provided solely as a matter of general information. Holders should not rely upon the following disclosure, or the disclosure under " Material Income Tax Consequences—United States Taxation" in the prospectus, with regard to an investment in any particular note because it does not take into account the terms of any particular note or the tax consequences of investing in or holding any particular note unless the pricing supplement applicable to the notes indicates that holders may rely on the following disclosure. Any note that holders purchase may have terms that would result in a tax treatment that is significantly different from the treatment described below. Consequently, any tax disclosure relevant to any note holders may purchase will be set forth only in the pricing supplement relating to the notes, and, unless the pricing supplement indicates otherwise, holders should not rely on the tax disclosure below or in the prospectus supplement or prospectus in deciding whether to invest in any note. In addition, this tax disclosure assumes the following for all notes issued pursuant to this underlying supplement: (i) any Reference Asset that is an equity security or shares of an exchange traded fund will be traded on a public exchange and is not an interest in a "United States real property holding corporation" (as such term is defined in the Code); (ii) any interest or coupon will be paid or payable at least annually and at equal intervals; (iii) in the case of notes paying fixed interest, the Interest Rate (as defined in the relevant pricing supplement) will not be below the market rate for non-contingent debt with terms similar to the notes; (iv) there is a significant possibility of a significant loss of principal on an investment in the notes; (v) initial purchasers will acquire the notes for an amount equal to their principal amount; and (vi) there is a reasonable likelihood that the value of the Reference Asset on the Final Valuation Date will be greater than or equal to the Initial Price.

This summary is directed solely to U.S. Holders and Non-U.S. Holders (each as defined in the prospectus) that, except as otherwise specifically noted, will purchase the notes upon original issuance and will hold the notes as capital assets within the meaning of Section 1221 of the Code, which generally means property held for investment, and that are not excluded from the discussion under "Material Income Tax Consequences—United States Taxation" in the accompanying prospectus.

Holders should consult their own tax advisors concerning the U.S. federal income tax consequences of acquiring, owning, and disposing of the notes, as well as any tax consequences arising under the laws of any state, local, foreign, or other tax jurisdiction and the possible effects of changes in U.S. federal or other tax laws.

 **General**

No statutory, judicial, or administrative authority directly addresses the characterization of the notes or any similar instruments for U.S. federal income tax purposes, and no ruling is being requested from the IRS with respect to their

------

proper characterization and treatment. Due to the absence of authorities on point, significant aspects of the U.S. federal income tax consequences of an investment in the notes are not certain, and no assurance can be given that the IRS or any court will agree with the characterization and tax treatment described in this underlying supplement. Accordingly, holders are urged to consult their tax advisors regarding all aspects of the U.S. federal income tax consequences of an investment in the notes, including possible alternative characterizations.

We will not attempt to ascertain whether the issuer of any component stocks included in the Reference Asset would be treated as a "passive foreign investment company" ("PFIC"), within the meaning of Section 1297 of the Code, or a United States real property holding corporation, within the meaning of Section 897(c) of the Code. If the issuer of one or more stocks included in the Reference Asset were so treated, certain adverse U.S. federal income tax consequences could possibly apply to a holder of the notes. Holders should refer to information filed with the SEC by the issuers of the component stocks included in the Reference Asset and consult their tax advisors regarding the possible consequences, if any, if any issuer of a component stock included in the Reference Asset is or becomes a PFIC or is or becomes a United States real property holding corporation.

**Notes Treated as Prepaid Derivative Contracts**

We may treat certain notes as prepaid derivative contracts for U.S. federal income tax purposes. The applicable pricing supplement will indicate whether we intend to treat a particular note as a prepaid derivative contract for U.S. federal income tax purposes. This section describes the principal U.S. federal income tax consequences of the purchase, beneficial ownership and disposition of a note that we intend to treat as a prepaid derivative contract for U.S. federal income tax purposes.

Although there is no statutory, judicial, or administrative authority directly addressing the characterization of the notes, we intend to treat notes described in this section for all U.S. federal income tax purposes as prepaid derivative contracts with respect to the Reference Asset and under the terms of the notes, we and every investor in the notes agree, in the absence of an administrative determination or judicial ruling to the contrary, to treat the notes in accordance with such characterization. This discussion assumes that the notes described in this section constitute prepaid derivative contracts with respect to the Reference Asset for U.S. federal income tax purposes. If the notes described in this section did not constitute prepaid derivative contracts, the tax consequences described below would be materially different.

Upon receipt of a cash payment at maturity or upon a sale, exchange or redemption of the notes prior to maturity, a U.S. Holder generally will recognize capital gain or loss equal to the difference between the amount realized (excluding amounts attributable to accrued but unpaid interest or coupons) and the U.S. Holder's tax basis in the notes. A U.S. Holder's tax basis in the notes will equal the amount paid by that holder to acquire them. This capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder held the notes for more than one year. The deductibility of capital losses is subject to limitations.

Although the tax treatment of any interest or coupon payments is unclear, we intend to treat any such payments, including on the Maturity Date, as ordinary income includible in income by U.S. Holders at the time it accrues or is received in accordance with such holder's normal method of accounting for U.S. federal income tax purposes.

**Notes Treated as Investment Units Consisting of a Debt Instrument and a Put Option**

We may treat certain notes as investment units consisting of a non-contingent debt instrument issued by CIBC to the holder (the "Debt Portion") and a put option written by the holder (the "Put Option"). The applicable pricing supplement will indicate whether we intend to treat a note as an investment unit for U.S. federal income tax purposes. This section describes the principal U.S. federal income tax consequences of the purchase, beneficial ownership and disposition of a note that we intend to treat as an investment unit for U.S. federal income tax purposes.

Although there is no statutory, judicial, or administrative authority directly addressing the characterization of the notes, we intend to treat notes described in this section for all U.S. federal income tax purposes as investment units and under the terms of the notes, we and every investor in the notes agree, in the absence of an administrative determination or judicial ruling to the contrary, to treat the notes in accordance with such characterization. This discussion assumes that the notes described in this section constitute investment units for U.S. federal income tax purposes. If the notes described in this section did not constitute investment units, the tax consequences described below would be materially different.

If the notes are properly treated as an investment unit consisting of a Debt Portion and Put Option, it is likely that the Debt Portion of the notes would be treated as having been issued for the principal amount of the notes and that interest payments on the notes would be treated in part as payments of interest and in part as payments for the Put Option. If

------

the notes have a term that exceeds one year, amounts treated as interest would be included in income in accordance with the holder's regular method of accounting for interest for U.S. federal income tax purposes. If the notes have a term of one year or less, amounts treated as interest would be subject to the rules governing short-term debt instruments (as described under "United States Taxation—Tax Consequences to U.S. Holders—Short-Term Securities" in the accompanying prospectus). Amounts treated as payment for the Put Option would be deferred and accounted for upon the sale, exchange, redemption or maturity of the notes, as discussed below.

If a holder were to receive a cash payment of the full principal amount of the notes upon the redemption or maturity of the notes (excluding cash received as interest), such payment would likely be treated as (i) payment in full of the principal amount of the Debt Portion and (ii) the lapse of the Put Option which would likely result in the recognition of short-term capital gain in an amount equal to the amount paid for the Put Option and deferred as described above. If a holder were to receive a cash payment upon the redemption or maturity of the notes (excluding cash received as interest) of less than the full principal amount of the notes, such payment would likely be treated as (i) payment in full of the principal amount of the Debt Portion (which would not result in the recognition of gain or loss if the holder is an initial purchaser of the notes) and (ii) the cash settlement of the Put Option pursuant to which the holder paid to us an amount equal to the excess of the principal amount of the notes over the amount received upon the maturity of the notes (excluding cash received as interest) in order to settle the Put Option. If the aggregate amount paid to a holder for the Put Option and deferred as described above is greater than the amount deemed to have been paid to us to settle the Put Option, a U.S. Holder will likely recognize short-term capital gain in an amount that is equal to such excess. Conversely, if the amount paid for the Put Option and deferred as described above is less than the amount deemed to have been paid to us to settle the Put Option, a U.S. Holder will likely recognize short-term capital loss in an amount that is equal to such difference. The deductibility of capital losses is subject to limitations.

If, instead of making a cash payment, we were to exchange the notes for shares of a Reference Asset of equivalent value, the receipt of such stock upon the maturity of the notes would likely be treated as (i) payment in full of the principal amount of the Debt Portion and (ii) the exercise by CIBC of the Put Option and the purchase of the shares of stock received for an amount equal to the principal amount of the notes. The U.S. federal income tax basis of the shares of stock received with respect to each note would equal the principal amount of the note less the amount of payments received for the Put Option and deferred as described above. The holding period in the shares of stock received would begin the day after a holder beneficially receives such shares of stock. If a holder receives cash in lieu of a fractional share of stock, such holder will be treated as having received such fractional share and then having received cash in exchange for such fractional share. U.S. Holders generally will recognize short-term capital gain or loss based on the difference between the amount of cash received in lieu of the fractional share and the U.S. federal income tax basis allocated to such fractional share. The deductibility of capital losses is subject to limitations.

Upon the sale or exchange of the notes, a U.S. Holder would be required to apportion the value of the amount received between the Debt Portion and Put Option on the basis of the values thereof on the date of the sale or exchange. A U.S. Holder would recognize gain or loss with respect to the Debt Portion in an amount equal to the difference between (i) the amount apportioned to the Debt Portion and (ii) such holder's adjusted U.S. federal income tax basis in the Debt Portion (which would generally be equal to the principal amount of the notes with respect to an initial purchaser of the notes). Except to the extent attributable to accrued but unpaid interest with respect to the Debt Portion, such gain or loss would be long-term capital gain or loss if a holder's holding period is greater than one year. The amount of cash received that is apportioned to the Put Option (together with any amount of premium received in respect thereof and deferred as described above) would be treated as short-term capital gain. If the value of the Debt Portion on the date of the sale or exchange of the notes is in excess of the amount received upon such sale or exchange, a holder would likely be treated as having made a payment (to the purchaser in the case of a sale or exchange) equal to the amount of such excess in order to extinguish the holder's rights and obligations under the Put Option. In such a case, a U.S. Holder would likely recognize short-term capital gain or loss in an amount equal to the difference between the premium previously received in respect of the Put Option and the amount of the deemed payment made by the holder to extinguish the Put Option.

**Alternative Tax Treatments**

Due to the absence of authorities that directly address the proper tax treatment of the notes, prospective investors are urged to consult their tax advisors regarding all possible alternative tax treatments of an investment in the notes. In particular, if the notes have a term that exceeds one year, the IRS could seek to subject the notes to the Treasury regulations governing contingent payment debt instruments. If the IRS were successful in that regard, the timing and character of income on the notes would be affected significantly. If the notes have a term in excess of one year, among other things, a U.S. Holder would be required to accrue original issue discount every year at a "comparable yield"

determined at the time of issuance. In addition, any gain realized by a U.S. Holder at maturity, or upon a sale, exchange or redemption of the notes generally would be treated as ordinary income, and any loss realized at maturity or upon a sale or exchange of the notes generally would be treated as ordinary loss to the extent of the U.S. Holder's prior accruals of original issue discount, and as capital loss thereafter. If the notes have a term of one year or less, the IRS could seek to subject the notes to the Treasury regulations governing short-term debt instruments. Although there is no authority that specifically addresses the tax treatment of short-term debt instruments subject to contingent payments, it is likely that, if the notes were so treated, a U.S. Holder should not recognize any income prior to the sale, exchange or redemption of the notes (except for any coupon payments on the notes, which will likely be taxable as ordinary income). Additionally, a U.S. Holder who uses the accrual method of accounting generally should be required to accrue any original issue discount on the notes on a straight-line basis. At maturity or upon a sale, exchange or redemption, a U.S. Holder using either a cash or accrual method of accounting generally should recognize taxable gain (all or a portion of which may be treated as ordinary income) or loss in an amount equal to the difference between the amount realized and such holder's tax basis in the notes.

If the notes are treated as described in the section "Notes Treated as Investment Units Consisting of a Debt Instrument and a Put Option," the IRS might assert that a U.S. Holder should be required to include the entire interest payment in income when received.

The IRS released Notice 2008-2 ("Notice") which sought comments from the public on the taxation of financial instruments currently taxed as "prepaid forward contracts." This Notice addresses instruments such as the notes. According to the Notice, the IRS and Treasury are considering whether a holder of an instrument such as the notes should be required to accrue ordinary income on a current basis, regardless of whether any payments are made prior to maturity. It is not possible to determine what guidance the IRS and Treasury will ultimately issue, if any. Any such future guidance may affect the amount, timing and character of income, gain, or loss in respect of the notes, possibly with retroactive effect.

The IRS and Treasury are also considering additional issues, including whether additional gain or loss from such instruments should be treated as ordinary or capital, whether foreign holders of such instruments should be subject to withholding tax on any deemed income accruals, whether Section 1260 of the Code, concerning certain "constructive ownership transactions," generally applies or should generally apply to such instruments, and whether any of these determinations depend on the nature of the underlying asset.

In addition, proposed Treasury regulations require the accrual of income on a current basis for contingent payments made under certain notional principal contracts. The preamble to the regulations states that the "wait and see" method of accounting does not properly reflect the economic accrual of income on those contracts, and requires current accrual of income for some contracts already in existence. While the proposed regulations do not apply to prepaid forward contracts, the preamble to the proposed regulations expresses the view that similar timing issues exist in the case of prepaid forward contracts. If the IRS or Treasury publishes future guidance requiring current economic accrual for contingent payments on prepaid forward contracts, it is possible that a U.S. Holder could be required to accrue income over the term of the notes.

Because of the absence of authority regarding the appropriate tax characterization of the notes, it is also possible that the IRS could seek to characterize the notes in a manner that results in tax consequences that are different from those described above. For example, the IRS could possibly assert that any gain or loss that a holder may recognize at maturity or upon the sale, exchange or redemption of the notes should be treated as ordinary gain or loss.

It is possible that the IRS could assert that a U.S. Holder's holding period in respect of the notes should end on the first calculation date during the Valuation Period, even though such holder will not receive any amounts in respect of the notes prior to the redemption or maturity of the notes. In such case, if the first calculation date during the Valuation Period is not in excess of one year from the original issue date, a U.S. Holder may be treated as having a holding period in respect of the notes equal to one year or less, in which case any gain or loss such holder recognizes at such time would be treated as short-term capital gain or loss.

If a Reference Asset is or includes an index that periodically rebalances, it is possible that the notes could be treated as a series of prepaid derivative contracts, each of which matures on the next rebalancing date. If the notes were properly characterized in such a manner, a U.S. Holder would be treated as disposing of the notes on each rebalancing date in return for new notes that mature on the next rebalancing date, and a U.S. Holder would accordingly likely recognize capital gain or loss on each rebalancing date equal to the difference between the holder's tax basis in the notes (which would be adjusted to take into account any prior recognition of gain or loss) and the fair market value of the notes on such date.

**Non-U.S. Holders**

Except as provided below, we do not intend to treat amounts paid to a Non-U.S. Holder in respect of the notes as subject to U.S. federal income or withholding tax, provided that the Non-U.S. Holder complies with applicable certification requirements and that the payment is not effectively connected with the conduct by the Non-U.S. Holder of a U.S. trade or business. Notwithstanding the foregoing, payments on the notes may be subject to U.S. federal income tax if that Non-U.S. Holder is a non-resident alien individual and is present in the U.S. for 183 days or more during the taxable year of the settlement at maturity, sale, exchange or redemption and certain other conditions are satisfied.

If a Non-U.S. Holder of the note is engaged in the conduct of a trade or business within the U.S. and payments in respect of the notes are effectively connected with the conduct of such trade or business (and, if certain tax treaties apply, is attributable to a permanent establishment maintained by the Non-U.S. Holder in the U.S.), the Non-U.S. Holder generally will be subject to U.S. federal income tax on payments in respect of payments on the notes on a net income basis in the same manner as if it were a U.S. Holder. Such Non-U.S. Holders should read the material under the heading "—U.S. Holders," for a description of the U.S. federal income tax consequences of acquiring, owning, and disposing of the notes. In addition, if such Non-U.S. Holder is a foreign corporation, it may also be subject to a branch profits tax equal to 30% (or such lower rate provided by any applicable tax treaty) of a portion of its earnings and profits for the taxable year that are effectively connected with its conduct of a trade or business in the U.S., subject to certain adjustments.

A "dividend equivalent" payment is treated as a dividend from sources within the United States and such payments generally would be subject to a 30% U.S. withholding tax if paid to a Non-U.S. Holder. Under Treasury regulations, payments (including deemed payments) with respect to equity-linked instruments ("ELIs") that are "specified ELIs" may be treated as dividend equivalents if such specified ELIs reference an interest in an "underlying security," which is generally any interest in an entity taxable as a corporation for U.S. federal income tax purposes if a payment with respect to such interest could give rise to a U.S. source dividend. However, Internal Revenue Service guidance provides that withholding on dividend equivalent payments will not apply to specified ELIs that are not delta-one instruments and that are issued before January 1, 2027. Except as otherwise set forth in any applicable pricing supplement, we expect that the delta of notes issued pursuant to this underlying supplement with respect to the Reference Asset will not be one, and therefore, we expect that Non-U.S. Holder should not be subject to withholding on dividend equivalent payments, if any, under the notes. However, it is possible that the notes could be treated as deemed reissued for U.S. federal income tax purposes upon the occurrence of certain events affecting the Reference Asset or the notes, and following such occurrence the notes could be treated as subject to withholding on dividend equivalent payments. Non-U.S. Holders that enter, or have entered, into other transactions in respect of the Reference Asset or the notes should consult their tax advisors as to the application of the dividend equivalent withholding tax in the context of the notes and their other transactions. If any payments are treated as dividend equivalents subject to withholding, we (or the applicable paying agent) would be entitled to withhold taxes without being required to pay any additional amounts with respect to amounts so withheld.

As discussed above, alternative characterizations of the notes for U.S. federal income tax purposes are possible. Should an alternative characterization, by reason of change or clarification of the law, by regulation or otherwise, cause payments as to the notes to become subject to withholding tax or, if we determine that there is a material risk that we are required to withhold on any payments on the notes, tax will be withheld at the applicable statutory rate. As discussed above, the IRS has indicated in the Notice that it is considering whether income in respect of instruments such as the notes should be subject to withholding tax. Prospective Non-U.S. Holders of the notes should consult their own tax advisors in this regard.

**U.S. Backup Withholding and Information Reporting**

Please see the discussions under "Material Income Tax Consequences—United States Taxation—Tax Consequences to U.S. Holders —U.S. Backup Withholding and Information Reporting" and "Material Income Tax Consequences—United States Taxation—Tax Consequences to Non-U.S. Holders—Backup Withholding and Information Reporting for Non-U.S. Holders" in the accompanying prospectus for a description of the applicability of the backup withholding and information reporting rules to payments made on the notes.
