HOW IT WORKS

Annual Coupon Payments

The Notes may make annual Coupon Payments on the sixteenth (16th) calendar day of each August (or if such day is not a business day, the next succeeding business day) during the term of the Notes. The Coupon Rate for each Coupon Payment Date is variable and can be no higher than 12.00% and no lower than 0.00%. The determination of the variable Coupon Rates is based on the price performance of a basket of ten (10) large-cap global Stocks. If the variable annual Coupon Rate is 0.00% for any scheduled Coupon Payment Date, then there will be no Coupon Payment on such scheduled Coupon Payment Date.

Variable Coupon Rate

The variable Coupon Rate for each of the Coupon Payment Dates on August 16, 2007 and August 18, 2008 is linked to the price performance of an equally weighted basket of the following ten (10) large-cap global Stocks (the “Stocks”).

The Stocks

NYSE = New York Stock Exchange, NASDAQ = NASDAQ Stock Market, TSX = Toronto Stock Exchange, LSE = London Stock Exchange, TSE = Tokyo Stock Exchange, HEX = Helsinki Stock Exchange, VTX = Zurich virt-x Exchange

The variable Coupon Rate on any Coupon Payment Date may be no higher than 12.00% regardless of how well the Stocks perform. Likewise, the variable Coupon Rate on any Coupon Payment Date may be no lower than 0.00% regardless of how poorly the Stocks perform. The specific mechanics of the determination of the variable Coupon Rates based on the performance of the Stocks is discussed in the section “Calculating The Variable Annual Coupon Rate” on page 4.

The Maturity Date Of The Notes

The Maturity Date of the Notes is the Stated Maturity Date of August 18, 2008.

Payments On The Maturity Date

The Notes are 100% principal protected. On the Maturity Date, we will pay the full principal amount of the Notes and the final Coupon Payment, if any.

HOW IT WORKS

Calculating The Variable Annual Coupon Rate

The variable annual Coupon Rate is determined three (3) Trading Days prior to each Coupon Payment Date. These dates are called the Valuation Dates or the Coupon Determination Dates. The first Coupon Determination Date is August 13, 2007. The second and final Coupon Determination Date is August 13, 2008. The Coupon Determination Dates may be adjusted as set forth in the related Product Supplement No. YGN-1.

The variable annual Coupon Rate for each Coupon Payment, determined on each Coupon Determination Date is equal to the greater of:

(i)             0.00%; and

(ii)          the average, which may be positive or negative, of the Stock Performances of the individual Stocks, equally weighted.

Calculating The Stock Performance For Each Stock

The Stock Performance for each Coupon Payment Date for each Stock is:

(i)             12.00% if the closing price of the Stock on the Coupon Determination Date is greater than the closing price of the Stock on August 11, 2006 (the Initial Stock Price) or

(ii)          0.00% if the closing price of the Stock on the Coupon Determination Date is equal to the Initial Stock Price on August 11, 2006; or

(iii)       the Cumulative Price Return of the Stock on the Coupon Determination Date, which is:

                        if the closing price of the Stock on the Coupon Determination Date is less than the Initial Stock Price on August 11, 2006.

The Stock Performance for each Stock can also be depicted graphically, as shown below. Stock Performance is plotted on the vertical axis while Cumulative Price Return is plotted on the horizontal axis.

- 4 -

HOW IT WORKS

The Variable Annual Coupon Rate and The Stocks

The Stock Performance of each Stock for purposes of calculating the variable annual Coupon Rate on any Coupon Determination Date is 12.00% as long as the Stock’s closing price on the Coupon Determination Date (the Valuation Stock Price) is greater than its closing price on August 11, 2006 (the Initial Stock Price). The Stock Performance is 12.00% regardless of the magnitude of the price increase. Stocks with small or even fractional price increases will have the same 12.00% Stock Performance as Stocks with large price increases.

The variable annual Coupon Rate is the greater of (i) 0.00% and (ii) the average, which may be positive or negative, of the Stock Performances of the individual Stocks, equally weighted. The Stock Performance for each Stock can never be higher than 12.00%. The highest that the annual Coupon Rate can be is therefore 12.00%, which is the Maximum Variable Coupon Rate. The Coupon Rate will be 12.00% if the closing prices of all of the Stocks on a Coupon Determination Date are greater than their Initial Stock Prices (since the Stock Performance for each Stock would be 12.00%, the average of the Stock Performances would be 12.00% as well). The Coupon Rate will be less than 12.00% if the closing price of one or more of the Stocks does not increase between the Pricing Date and the Coupon Determination Date.

The calculation of the Stock Performance for each Stock is designed to result in above-market annual Coupon Rates relative to fixed-income alternatives of comparable credit quality and maturity even with only modest price performance from the Stocks.

The Coupon Determination Date for the first variable annual Coupon Payment is on August 13, 2007. The Stocks have a full year to produce the small or even fractional price gains required to generate a Coupon Rate of up to 12.00% payable on August 16, 2007. Similarly, the Stocks have two full years to produce a small or even fractional price gain for the second and final annual Coupon Payment on August 18, 2008. However, the Valuation Stock Price for each Stock is determined only on each Coupon Determination Date and therefore will reflect the performance of the Stocks only on such date.

Price declines reduce the variable annual Coupon Rate. The Stock Performance of a Stock whose price has declined is the negative percentage decline in that Stock’s price (its Cumulative Price Return). The negative Stock Performance of a Stock is not limited like its positive Stock Performance. Large price increases will not offset large price declines, as is illustrated in Hypothetical Example Two.

A large price decline in just one or two Stocks could cause the variable annual Coupon Rate to be small or even 0.00%. The variable annual Coupon Rate can never be lower than 0.00%.

U.S. Federal Income Tax Considerations

The initial issue price of the Notes will be $1,000. We have determined that the comparable yield for the Notes is 5.55%, compounded semi-annually. If the comparable yield were successfully challenged by the Internal Revenue Service (the “IRS”), the redetermined yield could be materially different from the comparable yield (for U.S. Federal income tax purposes) provided by us, and the projected payment schedule could also differ materially from the schedule provided by us, as set out below. Based on the comparable yield, if you are an initial holder that holds a Note to maturity, and you pay your taxes on a calendar year basis, you would generally have to include as interest income each year the amounts set forth under “OID Accrual” in the chart below (subject to adjustment as described in the discussion under “Supplemental U.S. Federal Income Tax Consequences” in the related Product Supplement No. YGN-1). The “Interest Income” columns in the chart below show the general results of such adjustments to interest income each year.

Notice Pursuant to I.R.S. Circular 230. This discussion is not intended or written by CIBC or by its counsel to be used, and cannot be used, by any person for the purpose of avoiding tax penalties that may be imposed under U.S. tax laws. This discussion is provided to support the promotion and marketing of the Notes by CIBC. Each taxpayer should seek advice based on the taxpayer’s particular circumstances from an independent tax advisor concerning the potential tax consequences of an investment in Notes.

Currency Considerations

A direct investment in any of the foreign Stocks would normally be exposed to changes in the exchange rates between the U.S. dollar and the relevant foreign currency. Generally, the return in U.S. dollar terms earned by U.S. investors on foreign stocks is helped by decreases in the value of the U.S. dollar relative to the foreign currency. Likewise, the return in U.S. dollar terms would be negatively impacted by increases in the U.S. dollar relative to the foreign currency.

The Coupon Payments on the Notes  (if any) are not adjusted for changes in the exchange rate between the U.S. dollar and any foreign currency. The applicable Coupon Rate for each Coupon Payment Date will reflect the closing prices of each Stock on its principal exchange on each Valuation Date (the Valuation Stock Price) through the calculation of the Stock Performance of each Stock on such Valuation Date and, if the average of the Stock Performances is greater than zero, the Coupon Payment will be paid to investors in U.S. dollars.

Please see the discussion of currency risk in the “Risk Factors” section in this Terms and Highlights Summary No. 31 and in the related Product Supplement No. YGN-1.

HOW IT WORKS

Hypothetical Example One – Annual Coupon Rate Calculation

Hypothetical Example One below graphically illustrates the calculation of a hypothetical variable annual Coupon Rate. The closing prices of eight of the ten Stocks in this hypothetical example were higher on the Coupon Determination Date than their Initial Stock Prices, and the closing prices of two of the Stocks were lower. The Stocks whose prices were higher on the Coupon Determination Date contribute to the Coupon Rate by the amount of their Stock Performances, or 12.00%. The Stocks whose closing prices were lower reduce the annual Coupon Rate by the amount of their Stock Performances of -2.00% and -5.00%, respectively.

The calculation of the average of the Stock Performances is shown in the right-most column of the chart. Since the average Stock Performance of 8.90% is greater than 0.00%, the hypothetical variable annual Coupon Rate is 8.90%.

This hypothetical example shows how small or even fractional price increases in the Stocks can result in above market annual Coupon Rates relative to fixed income alternatives of comparable credit quality and maturity.

Hypothetical Example

HOW IT WORKS

Hypothetical Example Two – Annual Coupon Rate Calculation

Hypothetical Example Two below illustrates the calculation of another hypothetical variable annual Coupon Rate. The closing prices of six of the ten Stocks in this hypothetical example were higher on the Coupon Determination Date than their Initial Stock Prices, the closing prices of three of the Stocks were significantly lower, and the closing price of one Stock did not change. The Stocks whose closing prices were higher contribute to the Coupon Rate by the amount of their Stock Performances, or 12.00%. The Stock whose closing price was unchanged contributes nothing to the annual Coupon Rate. The Stocks whose closing prices were lower reduce the annual Coupon Rate by the amount of their Stock Performances of -16.00%, -25.00% and -47.00%, respectively.

The calculation of the average of the Stock Performances is shown in the right-most column of the chart. Since the average Stock Performance of -1.60% is less than 0.00%, the hypothetical variable annual Coupon Rate is 0.00% (the variable annual Coupon Rate can be no lower than 0.00%). Thus, in this hypothetical, there would be no Coupon Payment.

This hypothetical example shows the negative impact that significant price declines in just a few Stocks can have on the variable annual Coupon Rate.

RISK FACTORS

An investment in the Notes involves significant risks. Investing in the Notes is not equivalent to investing directly in the Stocks. These risks are explained in more detail in the “Risk Factors” section of the related Product Supplement No. YGN-1.

You may not receive Coupon Payments on your Notes.

The average of the Stock Performances of the ten individual Stocks must be positive when the Coupon Rate is determined for there to be a Coupon Payment. The Stock Performances will be determined only by the Valuation Stock Prices on each Coupon Determination Date, and thus will not reflect the performance of the Stocks (whether positive or negative) on any other date during the term of the Notes.

Owning the Notes is different from owning the Stocks individually or conventional debt securities.

The return on your Notes will not reflect the return you would realize if you actually owned the Stocks or conventional debt securities and held such investment for a similar period because:

•              Principal Protected. At a minimum, you will receive the full principal amount of your Notes if the Notes are held to maturity.

•              Capped Coupon Rate. The maximum Coupon Rate for any Coupon Payment Date is 12.00%.

•              Weighted Return. Because the Coupon Payments will equal the average return of ten Stocks and no individual Stock can have a performance rate that exceeds 12.00%, negative performance rates of one or more Stock(s) (which are not limited) could offset gains made by other Stocks.

•              Correlation of Performance. Performance among the Stocks may become highly correlated over time, which may minimize the beneficial timing or hedging effect derived from inversely related investments.

•              No Dividend. The method of calculating performance of the Stocks does not take into account dividends paid on those Stocks. Therefore, if a dividend is paid, the performance rate on a Stock will be lower than the actual return a holder of that Stock would realize.

The market value of your Notes before maturity will depend on a number of factors, and may be substantially less than you had originally invested.

We believe that the value of the Notes will be affected by the supply of and demand for the Notes, the value of the Stocks on each Valuation Date, market interest rates and a number of other factors. The key factors we believe will impact the market value of the Notes include the value and volatility of the Stocks, interest rates, our credit rating and our financial condition and general economic conditions.

We are not affiliated with the stock issuers and have not investigated them.

We and our affiliates are not affiliated with any of the stock issuers and have not performed any due diligence investigation or review of any of them. We assume no responsibility for the adequacy of any information concerning these companies contained in this Terms and Highlights Summary No. 31 or publicly available.

There are risks associated with investments in securities indexed to the value of foreign equity securities.

Some of the Stocks are issued by companies in countries outside of the United States.  Investments in securities indexed to the value of foreign equity securities involve risks associated with the securities markets in those countries, including risks of volatility in those markets, governmental intervention as well as political, economic, financial and social factors in those countries, or global regions, including changes in government, economic and fiscal policies and currency exchange laws.

Trading and other transactions by us and our affiliates in the Stocks may impair the value of your Notes.

We, through one or more of our other affiliates, may hedge our obligations under the Notes by purchasing the Stocks. We expect to adjust the hedge by, among other things, purchasing or selling one or more of the Stocks, and perhaps listed or over-the-counter options, futures or other instruments linked to one or more of the Stocks, at any time and from time to time. In addition, our affiliates may engage in trading in one or more of the Stocks, or in instruments whose returns are linked to one or more of those Stocks, for their proprietary accounts, for other accounts under their management or to facilitate transactions, including block transactions, on behalf of customers. Any of these hedging activities may adversely affect the performance rates of the Stocks—directly or indirectly by affecting the market prices of the Stocks—and, therefore, the value of your Notes.

- 10 -

RISK FACTORS

The performances of the Stocks may not be fully protected from dilutive or reorganization events involving the issuers of those Stocks.

As calculation agent for your Notes, we will adjust the Initial Stock Price of each Stock for stock splits, reverse stock splits, stock dividends and similar events that affect the issuer’s capital structure, but only in the situations described in the related Product Supplement No. YGN-1. The calculation agent is not required to make an adjustment for every corporate event that may affect the Stocks, and such other events may adversely affect the market price of a Stock and, therefore, adversely affect the value of your Note.

You will be required to pay taxes on your Notes each year.

For United States federal income tax purposes, the Notes are classified as debt instruments that provide for contingent interest. Under the rules applicable to debt instruments that provide for contingent interest, you generally will be required to include interest income each year you hold the Notes, regardless of whether a Coupon Payment is made on the Notes, including some interest income in 2006 representing interest accruals in advance of the first Coupon Payment in 2007. Additionally, because the Notes will be classified as debt instruments that provide for contingent interest, you generally will be required to recognize ordinary income on the gain, if any, realized on a sale, upon maturity, or other disposition of the Notes. See “U.S. Federal Income Tax Considerations” in this Terms and Highlights Summary No. 31 as well as the discussion under “Supplemental U.S. Federal Income Tax Consequences” in the related Product Supplement No. YGN-1.

Notice Pursuant To I.R.S. Circular 230. This discussion is not intended or written by CIBC or by its counsel to be used, and cannot be used, by any person for the purpose of avoiding tax penalties that may be imposed under U.S. tax laws. This discussion is provided to support the promotion and marketing by CIBC of the Notes. Each taxpayer should seek advice based on the taxpayer’s particular circumstances from an independent tax advisor concerning the potential tax consequences of an investment in Notes.

Historical performance of the Stocks should not be taken as an indication of the future performance of the Stocks during the term of the Notes.

The trading prices of the Stocks on each Valuation Date will determine the Coupon Rates. As a result, it is impossible to predict whether there will be Coupon Payments or the amount of any such Coupon Payment.

Secondary trading may be limited.

The Notes will not be listed on any securities exchange.  There may be little or no secondary market for the Notes.  Even if there is a secondary market, it may not provide enough liquidity to allow you to trade or sell the Notes easily.

There are potential conflicts of interest because we will also act as the calculation agent.

We will initially serve as the calculation agent. We will, among other things, decide the Valuation Stock Price for each Stock on each Valuation Date and the Coupon Rate for each Coupon Payment, make antidilution adjustments and make other relevant determinations regarding the Notes.

We can postpone a Valuation Date for one or more of the Stocks, and therefore postpone a Coupon Payment Date or the Maturity Date, if a market disruption event with respect to one or more of the Stocks occurs on a Valuation Date for such Stock.

In our role as calculation agent, we may postpone a Coupon Payment Date if we determine that on the Valuation Date for a Stock a market disruption event has occurred or is continuing for that Stock. If the determination of the Valuation Stock Price of a Stock is postponed to the last possible day as a result of a market disruption event (as described in more detail in the related Product Supplement No. YGN-1), but a market disruption event with respect to such Stock occurs or is continuing on that day, that day will nevertheless be the date on which the Valuation Stock Price of such Stock will be determined. In such an event, in our role as calculation agent, we will determine the Valuation Stock Price of the affected Stock(s) using the trading or quoted price for such Stock(s) on that date. This determination may involve estimating the Valuation Stock Price of the affected Stock(s). If the final Valuation Date for one or more Stocks is postponed due to a market disruption event, the Maturity Date will be postponed to three business days after the last rescheduled Valuation Date.
