INVESTMENT DESCRIPTION

The Principal at Risk Securities Linked to the S&P 500® Index due January 3, 2019 (the “securities”) are senior unsecured debt securities of Canadian Imperial Bank of Commerce that do not pay interest at a specified rate or repay a fixed amount of principal at maturity. Instead, the securities provide for a payment at maturity that may be greater than, equal to or less than the principal amount of the securities depending on the performance of the S&P 500®  Index (the “Index”) from its starting level on the pricing date to its ending level on the calculation date. The securities provide:

(i)                                     the possibility of a 200% leveraged return at maturity if the level of the Index increases from its starting level to its ending level, provided that the total return at maturity of the securities will not exceed the maximum total return of 8.1% of the principal amount;

(ii)                                  repayment of principal if, and only if, the ending level of the Index is not less than the starting level by more than 7.5%; and

(iii)                               1-to-1 downside exposure to decreases in the level of the Index if and to the extent the ending level is less than the starting level by more than 7.5%.

If the ending level is less than the starting level by more than 7.5%, you will receive at maturity less, and up to 92.5% less, than the principal amount of your securities. All payments on the securities are subject to the credit risk of Canadian Imperial Bank of Commerce.

The Index is an equity index that is intended to provide an indication of the pattern of common stock price movement in the large capitalization segment of the United States equity market.

The S&P 500® Index is a product of S&P Dow Jones Indices LLC (“SPDJI”), and has been licensed for use by us.

INVESTOR CONSIDERATIONS

We have designed the securities for investors who:

·                  seek 200% leveraged exposure to any upside performance of the Index if the ending level is greater than the starting level, subject to the maximum total return at maturity of  8.1% of the principal amount;

·                  desire to limit downside exposure to the Index through the 7.5% buffer;

·                  understand that if the ending level is less than the starting level by more than 7.5%, they will receive at maturity less, and up to 92.5% less, than the principal amount per security;

·                  are willing to forgo periodic interest payments on the securities and dividends on securities included in the Index; and

·                  are willing to hold the securities until maturity.

The securities are not designed for, and may not be a suitable investment for, investors who:

·                  seek a liquid investment or are unable or unwilling to hold the securities to maturity;

·                  are unwilling to accept the risk that the ending level of the Index may decrease by more than 7.5% from the starting level;

·                  seek uncapped exposure to the upside performance of the Index;

·                  seek full return at maturity of the principal amount of the securities;

·                  are unwilling to purchase securities with an estimated value as of the pricing date that is lower than the principal amount;

·                  seek current income (including income in the form of periodic interest payments);

·                  are unwilling to accept the risk of exposure to the large capitalization segment of the United States equity market;

·                  seek exposure to the Index but are unwilling to accept the risk/return trade-offs inherent in the payment at stated maturity for the securities;

·                  are unwilling to accept the credit risk of Canadian Imperial Bank of Commerce to obtain exposure to the Index generally, or to the exposure to the Index that the securities provide specifically; or

·                  prefer the lower risk of fixed income investments with comparable maturities issued by companies with comparable credit ratings.

TERMS OF THE SECURITIES

The information in this “Terms of the Securities” section is only a summary and is qualified by the more detailed information set forth in this pricing supplement, the prospectus supplement dated March 28, 2017 and the prospectus dated March 28, 2017, each filed with the SEC. See “About This Pricing Supplement” in this pricing supplement.

DETERMINING PAYMENT AT MATURITY

On the stated maturity date, you will receive a cash payment per security (the redemption amount) calculated as follows:

PRS-8

HYPOTHETICAL PAYOUT PROFILE

The following profile is based on a capped value of 108.1% or $1,081 per security, a participation rate of 200% and a threshold level equal to 92.5% of the starting level. This graph has been prepared for purposes of illustration only. Your actual return will depend on the actual ending level and whether you hold your securities to maturity.

PRS-9

RISK FACTORS

The securities have complex features and investing in the securities will involve risks not associated with an investment in conventional debt securities or in the Index. You should carefully consider the risk factors set forth below as well as the other information contained in this pricing supplement and the accompanying prospectus supplement and prospectus, including the documents they incorporate by reference. As described in more detail below, the value of the securities may vary considerably before the stated maturity date due to events that are difficult to predict and are beyond our control. You should reach an investment decision only after you have carefully considered with your advisors the suitability of an investment in the securities in light of your particular circumstances.

If The Ending Level Is Less Than The Threshold Level, You Will Receive At Maturity Less, And Up To 92.5% Less, Than The Principal Amount Of Your Securities.

We will not repay you a fixed amount on the securities on the stated maturity date. The redemption amount will depend on the direction of and percentage change in the ending level of the Index relative to the starting level and the other terms of the securities. Because the level of the Index will be subject to market fluctuations, the redemption amount you receive may be more or less, and possibly significantly less, than the principal amount of your securities.

If the ending level is less than the threshold level, the redemption amount that you receive at stated maturity will be reduced by an amount equal to the decline in the level of the Index to the extent it is below the threshold level (expressed as a percentage of the starting level). The threshold level is 92.5% of the starting level. As a result, you may receive less, and up to 92.5% less, than the principal amount per security at maturity even if the level of the Index is greater than or equal to the starting level or the threshold level at certain times during the term of the securities.

Even if the ending level is greater than the starting level, the amount you receive at stated maturity may only be slightly greater than the principal amount, and your yield on the securities may be less than the yield you would earn if you bought a traditional interest-bearing debt security of Canadian Imperial Bank of Commerce or another issuer with a similar credit rating with the same stated maturity date.

Your Return Will Be Limited By The Capped Value And May Be Lower Than The Return On A Direct Investment In The Index.

The opportunity to participate in the possible increases in the level of the Index through an investment in the securities will be limited because the redemption amount will not exceed the capped value. Furthermore, the effect of the participation rate will be progressively reduced for all ending levels exceeding the ending level at which the capped value is reached.

Your Return On The Securities Could Be Less Than If You Owned Securities Included In The Index.

Your return on the securities will not reflect the return you would realize if you actually owned the securities included in the Index and  received the dividends and other payments paid on those securities. This is in part because the redemption amount payable at stated maturity will be determined by reference to the ending level of the Index, which will be calculated by reference to the prices of the securities in the Index without taking into consideration the value of dividends and other payments paid on those securities. In addition, the redemption amount will not be greater than the capped value.

No Periodic Interest Will Be Paid On The Securities.

No periodic interest will be paid on the securities. However, because it is possible that the securities may be classified for U.S. federal income tax purposes as contingent payment debt instruments rather than prepaid forward contracts, you may be required to accrue interest income over the term of your securities. See “Certain United States Federal Income Tax Considerations” in this pricing supplement.

PRS-10

The Securities Are Subject To The Credit Risk Of Canadian Imperial Bank of Commerce.

The securities are our obligations exclusively and are not, either directly or indirectly, an obligation of any third party. Any amounts payable under the securities are subject to our creditworthiness, and you will have no ability to pursue any securities included in the Index for payment. As a result, our actual and perceived creditworthiness and actual or anticipated decreases in our credit ratings may affect the value of the securities and, in the event we were to default on our obligations, you may not receive any amounts owed to you under the terms of the securities.

The Estimated Value Of The Securities Is Not An Indication Of The Price, If Any, At Which Wells Fargo Securities Or Any Other Person May Be Willing To Buy The Securities From You In The Secondary Market.

The price, if any, at which Wells Fargo Securities or any of its affiliates may purchase the securities in the secondary market will be based on Wells Fargo Securities’ proprietary pricing models and will fluctuate over the term of the securities as a result of changes in the market and other factors described in the next risk factor. Any such secondary market price for the securities will also be reduced by a bid-offer spread, which may vary depending on the aggregate principal amount of the securities to be purchased in the secondary market transaction, and the expected cost of unwinding any related hedging transactions. Unless the factors described in the next risk factor change significantly in your favor, any such secondary market price for the securities will likely be less than the principal amount.

If Wells Fargo Securities or any of its affiliates makes a secondary market in the securities at any time up to the issue date or during the three-month period following the issue date, the secondary market price offered by Wells Fargo Securities or any of its affiliates will be increased by an amount reflecting a portion of the costs associated with selling, structuring, hedging and issuing the securities that are included in the principal amount. Because this portion of the costs is not fully deducted upon issuance, any secondary market price offered by Wells Fargo Securities or any of its affiliates during this period will be higher than it would be if it were based solely on Wells Fargo Securities’ proprietary pricing models less the bid-offer spread and hedging unwind costs described above. The amount of this increase in the secondary market price will decline steadily to zero over this three-month period. If you hold the securities through an account at Wells Fargo Securities or one of its affiliates, we expect that this increase will also be reflected in the value indicated for the securities on your brokerage account statement. If you hold your securities through an account at a broker-dealer other than Wells Fargo Securities or any of its affiliates, the value of the securities on your brokerage account statement may be different than if you held your securities at Wells Fargo Securities or any of its affiliates.

The Value Of The Securities Prior To Stated Maturity Will Be Affected By Numerous Factors, Some Of Which Are Related In Complex Ways.

The value of the securities prior to stated maturity will be affected by the level of the Index at that time, interest rates at that time and a number of other factors, some of which are interrelated in complex ways. The effect of any one factor may be offset or magnified by the effect of another factor. The following factors, among others, are expected to affect the value of the securities. When we refer to the “value” of your security, we mean the value you could receive for your security if you are able to sell it in the open market before the stated maturity date.

·        Index Performance. The value of the securities prior to maturity will depend substantially on the level of the Index. The price at which you may be able to sell the securities before stated maturity may be at a discount, which could be substantial, from their principal amount, if the level of the Index at such time is less than, equal to or not sufficiently above its starting level.

·        Capped Value. We anticipate that the value of the securities will always be at a discount to the capped value.

·        Interest Rates. The value of the securities may be affected by changes in the interest rates in the U.S. markets.

PRS-11

·        Volatility Of The Index. Volatility is the term used to describe the size and frequency of market fluctuations. The value of the securities may be affected if the volatility of the Index changes.

·        Time Remaining To Maturity. The value of the securities at any given time prior to maturity will likely be different from that which would be expected based on the then-current level of the Index. This difference will most likely reflect a discount due to expectations and uncertainty concerning the level of the Index during the period of time still remaining to the maturity date. In general, as the time remaining to maturity decreases, the value of the securities will approach the amount that could be payable at maturity based on the then-current level of the Index.

·        Dividend Yields On Securities Included In The Index. The value of the securities may be affected by the dividend yields on securities included in the Index.

·        Events Involving Companies Included In The Index. General economic conditions and earnings results of the companies whose stocks are included in the Index and real or anticipated changes in those conditions or results may affect the value of the securities. Additionally, as a result of a merger or acquisition, one or more of the stocks in the Index may be replaced with a surviving or acquiring entity’s securities. The surviving or acquiring entity’s securities may not have the same characteristics as the stock originally included in the Index.

·        Our Credit Ratings, Financial Condition And Results Of Operation. Actual or anticipated changes in our credit ratings, financial condition or results of operation may affect the value of the securities. However, because the return on the securities is dependent upon factors in addition to our ability to pay our obligations under the securities, such as the level of the Index, an improvement in our credit ratings, financial condition or results of operation will not reduce the other investment risks related to the securities.

You should understand that the impact of one of the factors specified above, such as a change in interest rates, may offset some or all of any change in the value of the securities attributable to another factor, such as a change in the level of the Index.

Our Estimated Value Of The Securities Is Lower Than The Principal Amount Of The Securities.

Our estimated value is only an estimate using several factors. The principal amount of the securities exceeds our estimated value because costs associated with selling and structuring the securities, as well as hedging the securities, are included in the principal amount of the securities. See “The Estimated Value of the Securities” in this pricing supplement.

Our Estimated Value Does Not Represent Future Values Of The Securities And May Differ From Others’ Estimates.

Our estimated value of the securities was determined by reference to our internal pricing models when the terms of the securities were set. This estimated value was based on market conditions and other relevant factors existing at that time and our 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 securities that are greater than or less than our 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 value of the securities could change significantly based on, among other things, changes in market conditions, our creditworthiness, interest rate movements and other relevant factors, which may impact the price, if any, at which Wells Fargo Securities or any other person would be willing to buy securities from you in secondary market transactions. See “The Estimated Value of the Securities” in this pricing supplement.

Our Estimated Value Was Not Determined By Reference To Credit Spreads For Our Conventional Fixed-Rate Debt.

The internal funding rate used in the determination of our estimated value generally represents a discount from the credit spreads for our conventional fixed-rate debt. If we were to have used the interest rate implied by our conventional fixed-rate credit spreads, we would expect the economic terms of the securities to be more favorable to you. Consequently, our use of an internal funding rate had an adverse effect on the terms of the securities and could have an adverse effect on any secondary market prices of the securities. See “The Estimated Value of the Securities” in this pricing supplement.

PRS-12

The Securities Will Not Be Listed On Any Securities Exchange And We Do Not Expect A Trading Market For The Securities To Develop.

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

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 securities prior to stated maturity. This may affect the price you receive upon such sale. Consequently, you should be willing to hold the securities to stated maturity.

Historical Levels Of The Index Should Not Be Taken As An Indication Of The Future Performance Of The Index During The Term Of The Securities.

The trading prices of the securities included in the Index will determine the redemption amount payable at maturity to you. As a result, it is impossible to predict whether the ending level of the Index will fall or rise compared to its starting level. Trading prices of the securities included in the Index will be influenced by complex and interrelated political, economic, financial and other factors that can affect the markets in which those securities are traded and the values of those securities themselves. Accordingly, any historical levels of the Index do not provide an indication of the future performance of the Index.

Changes That Affect The Index May Adversely Affect The Value Of The Securities And The Amount You Will Receive At Stated Maturity.

The policies of the Index sponsor concerning the calculation of the Index and the addition, deletion or substitution of securities comprising the Index and the manner in which the Index sponsor takes account of certain changes affecting such securities may affect the level of the Index and, therefore, may affect the value of the securities and the redemption amount payable at maturity. The Index sponsor may discontinue or suspend calculation or dissemination of the Index or materially alter the methodology by which it calculates the Index. Any such actions could adversely affect the value of the securities.

We Cannot Control Actions By Any Of The Unaffiliated Companies Whose Securities Are Included In The Index.

Actions by any company whose securities are included in the Index may have an adverse effect on the price of its security, the ending level and the value of the securities. Wells Fargo & Company, an affiliate of Wells Fargo Securities, is currently one of the companies included in the Index, but we are not affiliated with any of the companies included in the Index.  These companies will not be involved in the offering of the securities and will have no obligations with respect to the securities, 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 securities and will not be responsible for, and will not have participated in, the determination of the timing of, prices for, or quantities of, the securities to be issued. These companies will not be involved with the administration, marketing or trading of the securities and will have no obligations with respect to the redemption amount to be paid to you at maturity.

We, Wells Fargo Securities, And Our Respective Affiliates Have No Affiliation With The Index Sponsor And Have Not Independently Verified Its Public Disclosure Of Information.

We, Wells Fargo Securities, and our respective affiliates are not affiliated in any way with the Index sponsor and have no ability to control or predict its actions, including any errors in or discontinuation of disclosure regarding the methods or policies relating to the calculation of the Index. We have derived the information about the Index sponsor and the Index contained herein from publicly available information, without independent verification. You, as an investor in the securities, should make your own investigation into the Index and the Index sponsor. The Index sponsor is not involved in the offering of the securities made hereby in any way and has no obligation to consider your interest as an owner of securities in taking any actions that might affect the value of the securities.

PRS-13

The Stated Maturity Date May Be Postponed In Certain Circumstances.

The determination of the ending level will be postponed if the originally scheduled calculation date  is not a trading day or if the calculation agent determines that a market disruption event has occurred or is continuing on that day. If such a postponement occurs, the stated maturity date will be postponed until the later of (i) three business days after the ending level is determined and (ii) the initial stated maturity date.

We Or One Of Our Affiliates Will Be The Calculation Agent And, As A Result, Potential Conflicts Of Interest Could Arise.

We or one of our affiliates will be the calculation agent for purposes of determining, among other things, the starting level and the ending level, calculating the redemption amount, determining whether adjustments should be made to the ending level, determining whether a market disruption event has occurred and, if publication of the Index is discontinued, selecting a successor or, if no successor is available, determining the closing level. Although the calculation agent will exercise its judgment in good faith when performing its functions, potential conflicts of interest may exist between the calculation agent and you.

Our Economic Interests And Those Of Any Dealer Participating In The Offering Of Securities Will Potentially Be Adverse To Your Interests.

You should be aware of the following ways in which our economic interests and those of any dealer participating in the distribution of the securities, which we refer to as a “participating dealer,” will potentially be adverse to your interests as an investor in the securities. In engaging in certain of the activities described below, our affiliates or any participating dealer or its affiliates may take actions that may adversely affect the value of and your return on the securities, and in so doing they will have no obligation to consider your interests as an investor in the securities. Our affiliates or any participating dealer or its affiliates may realize a profit from these activities even if investors do not receive a favorable investment return on the securities.

·        Research reports by our affiliates or any participating dealer or its affiliates may be inconsistent with an investment in the securities and may adversely affect the level of the Index. Our affiliates or any dealer participating in the offering of the securities or its affiliates may, at present or in the future, publish research reports on the Index or the companies whose securities are included in the Index. This research will be modified from time to time without notice and may, at present or in the future, express opinions or provide recommendations that are inconsistent with purchasing or holding the securities. Any research reports on the Index or the companies whose securities are included in the Index could adversely affect the level of the Index and, therefore, adversely affect the value of and your return on the securities. You are encouraged to derive information concerning the Index from multiple sources and should not rely on the views expressed by us or our affiliates or any participating dealer or its affiliates. In addition, any research reports on the Index or the companies whose securities are included in the Index published on or prior to the pricing date could result in an increase in the level of the Index on the pricing date, which would adversely affect investors in the securities by increasing the level at which the Index must close on the calculation date in order for investors in the securities to receive a favorable return.

·        Business activities of our affiliates or any participating dealer or its affiliates with the companies whose securities are included in the Index may adversely affect the level of the Index. Our affiliates or any participating dealer or its affiliates may, at present or in the future, engage in business with the companies whose securities are included in the Index, including making loans to those companies (including exercising creditors’ remedies with respect to such loans), making equity investments in those companies or providing investment banking, asset management or other advisory services to those companies. These business activities could adversely affect the level of the Index and, therefore, adversely affect the value of and your return on the securities. In addition, in the course of these business activities, our affiliates or any participating dealer or its affiliates may acquire non-public information about one or more of the companies whose securities are included in the Index. If our affiliates or any participating dealer or its affiliates do acquire such non-public information, we and they are not obligated to disclose such non-public information to you.

·        Hedging activities by our affiliates or any participating dealer or its affiliates may adversely affect the level of the Index. We expect to hedge our obligations under the securities through one or more hedge counterparties, which may include our affiliates or any participating dealer or its affiliates. Pursuant to such hedging activities, our hedge counterparty may acquire securities included in the Index or listed or over-the-counter derivative or synthetic instruments

PRS-14

related to the Index or such securities. Depending on, among other things, future market conditions, the aggregate amount and the composition of such positions are likely to vary over time. To the extent that our hedge counterparty has a long hedge position in any of the securities included in the Index, or derivative or synthetic instruments related to the Index or such securities, they may liquidate a portion of such holdings at or about the time of the calculation date or at or about the time of a change in the securities included in the Index. These hedging activities could potentially adversely affect the level of the Index and, therefore, adversely affect the value of and your return on the securities.

·        Trading activities by our affiliates or any participating dealer or its affiliates may adversely affect the level of the Index. Our affiliates or any participating dealer or its affiliates may engage in trading in the securities included in the Index and other instruments relating to the Index or such securities on a regular basis as part of their general broker-dealer and other businesses. Any of these trading activities could potentially adversely affect the prices of the securities included in the Index and, therefore, adversely affect the value of and your return on the securities.

·        A participating dealer or its affiliates may realize hedging profits projected by its proprietary pricing models in addition to any selling concession or any distribution expense fee, creating a further incentive for the participating dealer to sell the securities to you. If any participating dealer or any of its affiliates conducts hedging activities for us in connection with the securities, that participating dealer or its affiliates will expect to realize a projected profit from such hedging activities, and this projected profit will be in addition to any concession or distribution expense fee that the participating dealer receives for the sale of the securities to you. This additional projected profit may create a further incentive for the participating dealer to sell the securities to you.

The U.S. Federal Tax Consequences Of An Investment In The Securities Are Unclear.

There is no direct legal authority regarding the proper U.S. federal tax treatment of the securities, and we do not plan to request a ruling from the Internal Revenue Service. Consequently, significant aspects of the tax treatment of the securities are uncertain, and the Internal Revenue Service or a court might not agree with the treatment of the securities as pre-paid cash-settled derivative contracts. If the Internal Revenue Service were successful in asserting an alternative treatment of the securities, the tax consequences of the ownership and disposition of the securities might be materially and adversely affected. As described below under “Certain United States Federal Income Tax Considerations,” the U.S. Treasury Department and the Internal Revenue Service released a notice requesting comments on various issues regarding the U.S. federal income tax treatment of “prepaid forward contracts” and similar instruments. Any Treasury regulations or other guidance promulgated after consideration of these issues could materially and adversely affect the tax consequences of an investment in the securities, including the character and timing of income or loss and the degree, if any, to which income realized by non-U.S. persons should be subject to withholding tax, possibly with retroactive effect.

Furthermore, Section 871(m) of the Internal Revenue Code and Treasury regulations promulgated thereunder (“Section 871(m)”)  impose a withholding tax of up to 30% on dividend equivalents paid to non-U.S. investors in respect of certain financial instruments linked to U.S. equities. An IRS notice provides a general exemption for non-delta-one financial instruments issued prior to 2019. In addition, Section 871(m) does not apply to derivatives that reference qualified indices. Based on these rules, the securities should not be subject to withholding under Section 871(m). However, the IRS could challenge this conclusion.

Both U.S. and non-U.S. persons considering an investment in the securities should review carefully the section of this pricing supplement entitled “Certain United States Federal Income Tax Considerations” and consult their tax advisers regarding the U.S. federal tax consequences of an investment in the securities (including possible alternative treatments and the issues presented by the notice), as well as tax consequences arising under the laws of any state, local or non-U.S. taxing jurisdiction.

There Can Be No Assurance That The Canadian Federal Income Tax Consequences Of An Investment In The Securities Will Not Change In The Future.

There can be no assurance that Canadian federal income tax laws, the judicial interpretation thereof, or the administrative policies and assessing practices of the Canada Revenue Agency will not be changed in a manner that adversely affects investors. For a discussion of the Canadian federal income tax consequences of investing in the securities, please read the section entitled “Certain Canadian Federal Income Tax Considerations” in this pricing supplement as well as the section entitled “Material Income Tax Consequences—Canadian Taxation” in the accompanying prospectus dated March 28, 2017. You should consult your tax advisor with respect to your own particular situation.

HYPOTHETICAL PAYMENTS AT STATED MATURITY

Set forth below are four examples of payment at stated maturity calculations (rounded to two decimal places), reflecting a capped value of 108.1% or $1,081 per security, a starting level of  2673.61, a participation rate of 200%, and a threshold level of 92.5% of the starting level, and assuming hypothetical ending levels as indicated in the examples.

Example 1. Redemption amount is greater than the principal amount but less than the capped value:

Starting level: 2673.61

Hypothetical ending level: 2753.82

Since the hypothetical ending level is greater than the starting level, the redemption amount would equal:

On the stated maturity date you would receive $1,060.00  per security.

Example 2. Redemption amount is equal to the capped value:

Starting level: 2673.61

Hypothetical ending level: 3475.69

The redemption amount would be equal to the capped value since the capped value is less than:

On the stated maturity date you would receive $1,081.00 per security.

In addition to limiting your return on the securities, the capped value limits the positive effect of the participation rate. If the ending level is greater than the starting level, you will participate in the performance of the Index at a rate of 200% up to a certain point. However, the effect of the participation rate will be progressively reduced for ending levels that are greater than approximately 104.05% of the starting level since your return on the securities for any ending level greater than approximately 104.05% of the starting level will be limited to the capped value.

PRS-17

Example 3. Redemption amount is equal to the principal amount:

Starting level: 2673.61

Hypothetical ending level: 2539.93

Threshold level: 2473.08925, which is 92.5% of the starting level

Since the hypothetical ending level is less than the starting level, but not by more than 7.5%, you would not lose any of the principal amount of your securities.

On the stated maturity date you would receive $1,000.00 per security.

Example 4. Redemption amount is less than the principal amount:

Starting level: 2673.61

Hypothetical ending level: 1336.81

Threshold level: 2473.08925, which is 92.5% of the starting level

Since the hypothetical ending level is less than the starting level by more than 7.5%, you would lose a portion of the principal amount of your securities and receive the redemption amount equal to:

On the stated maturity date you would receive $575.00 per security.

To the extent that the actual ending level differs from the values assumed above, the results indicated above would be different.

ADDITIONAL TERMS OF THE SECURITIES

CIBC will issue the securities as part of a series of senior unsecured debt securities entitled “Senior Global Medium-Term Notes (Structured Notes),” which is more fully described in the accompanying prospectus supplement and prospectus. Information included in this pricing supplement supersedes information in the prospectus supplement and prospectus to the extent that it is different from that information.

Payment of Redemption Amount

In the event that the stated maturity date is not a business day, then the redemption amount will be paid on the next business day.

Market Disruption Events

A “market disruption event” means any of the following events as determined by the calculation agent in its sole discretion:

(A)       The occurrence or existence of a material suspension of or limitation imposed on trading by the relevant stock exchanges or otherwise relating to securities which then comprise 20% or more of the level of the Index or any successor equity index at any time during the one-hour period that ends at the close of trading on that day, whether by reason of movements in price exceeding limits permitted by those relevant stock exchanges or otherwise.

(B)       The occurrence or existence of a material suspension of or limitation imposed on trading by any related futures or options exchange or otherwise in futures or options contracts relating to the Index or any successor equity index on any related futures or options exchange at any time during the one-hour period that ends at the close of trading on that day, whether by reason of movements in price exceeding limits permitted by the related futures or options exchange or otherwise.

(C)       The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market values for, securities that then comprise 20% or more of the level of the Index or any successor equity index on their relevant stock exchanges at any time during the one-hour period that ends at the close of trading on that day.

(D)       The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the ability of market participants in general to effect transactions in, or obtain market values for, futures or options contracts relating to the Index or any successor equity index on any related futures or options exchange at any time during the one-hour period that ends at the close of trading on that day.

(E)        The closure on any exchange business day of the relevant stock exchanges on which securities that then comprise 20% or more of the level of the Index or any successor equity index are traded or any related futures or options exchange prior to its scheduled closing time unless the earlier closing time is announced by the relevant stock exchange or related futures or options exchange, as applicable, at least one hour prior to the earlier of (1) the actual closing time for the regular trading session on such relevant stock exchange or related  futures or options exchange, as applicable, and (2) the submission deadline for orders to be entered into the relevant stock exchange or related futures or options exchange, as applicable, system for execution at such actual closing time on that day.

(F)         The relevant stock exchange for any security underlying the Index or successor equity index or any related futures or options exchange fails to open for trading during its regular trading session.

For purposes of determining whether a market disruption event has occurred:

(1)         the relevant percentage contribution of a security to the level of the Index or any successor equity index will be based on a comparison of (x) the portion of the level of such index attributable to that security and (y) the overall level of the Index or successor equity index, in each case immediately before the occurrence of the market disruption event;

(2)         the “close of trading” on any trading day for the Index or any successor equity index means the scheduled closing time of the relevant stock exchanges with respect to the securities underlying the Index or successor equity index on such trading day; provided that, if the actual closing time of the regular trading session of any such relevant stock exchange is earlier than its scheduled closing time on such trading day, then (x) for purposes of clauses (A) and (C) of the definition of “market disruption event” above, with respect to any security underlying the Index or successor equity index for which such relevant stock exchange is its relevant stock exchange, the “close of trading” means such actual closing time and (y) for purposes of clauses (B) and (D) of the definition of “market disruption event” above, with respect to any futures or options contract relating to the Index or successor equity index, the “close of trading” means the latest actual closing time of the

PRS-19

regular trading session of any of the relevant stock exchanges, but in no event later than the scheduled closing time of the relevant stock exchanges;

(3)         the “scheduled closing time” of any relevant stock exchange or related futures or options exchange on any trading day for the Index or any successor equity index means the scheduled weekday closing time of such relevant stock exchange or related futures or options exchange on such trading day, without regard to after hours or any other trading outside the regular trading session hours; and

(4)         an “exchange business day” means any trading day for the Index or any successor equity index on which each relevant stock exchange for the securities underlying the Index or any successor equity index and each related futures or options exchange are open for trading during their respective regular trading sessions, notwithstanding any such relevant stock exchange or related futures or options exchange closing prior to its scheduled closing time.

If a market disruption event occurs or is continuing on the calculation date, then the calculation date will be postponed to the first succeeding trading day on which a market disruption event has not occurred and is not continuing; however, if such first succeeding trading day has not occurred as of the eighth trading day after the originally scheduled calculation date, that eighth trading day shall be deemed to be the calculation date. If the calculation date has been postponed eight trading days after the originally scheduled calculation date and a market disruption event occurs or is continuing on such eighth trading day, the calculation agent will determine the closing level of the Index on such eighth trading day in accordance with the formula for and method of calculating the closing level of the Index last in effect prior to commencement of the market disruption event, using the closing price (or, with respect to any relevant security, if a market disruption event has occurred with respect to such security, its good faith estimate of the value of such security at the scheduled closing time of the relevant stock exchange for such security or, if earlier, the actual closing time of the regular trading session of such relevant stock exchange) on such date of each security included in the Index. As used herein, “closing price” means, with respect to any security on any date, the relevant stock exchange traded or quoted price of such security as of the scheduled closing time of the relevant stock exchange for such security or, if earlier, the actual closing time of the regular trading session of such relevant stock exchange.

Adjustments to the Index

If at any time a sponsor or publisher of the Index (the “Index sponsor”) makes a material change in the formula for or the method of calculating the 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 closing level of the Index is to be calculated, 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 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.

Discontinuance of the Index

If the Index sponsor discontinues publication of the Index, and such 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 equity index”), then, upon the calculation agent’s notification of that determination to the trustee and Canadian Imperial Bank of Commerce, the calculation agent will substitute the successor equity index as calculated by the relevant Index sponsor or any other entity and calculate the ending level as described above. Upon any selection by the calculation agent of a successor equity index, Canadian Imperial Bank of Commerce will cause notice to be given to holders of the securities.

In the event that the Index sponsor discontinues publication of the Index prior to, and the discontinuance is continuing on, the calculation date and the calculation agent determines that no successor equity index is available at such time, the calculation agent will calculate a substitute closing level for 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 that discontinuance. If a successor equity index is selected or the calculation agent calculates a level as a substitute for the Index, the successor equity index or level will be used as a substitute for the Index for all purposes, including the purpose of determining whether a market disruption event exists.

PRS-20

If on the calculation date 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 above under “—Market Disruption Events” 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, the Index may adversely affect the value of the securities.

Calculation Agent

We or one of our affiliates will act as calculation agent for the securities and may appoint agents to assist it in the performance of its duties. See “Risk Factors—We Or One Of Our Affiliates Will Be The Calculation Agent And, As A Result, Potential Conflicts Of Interest Could Arise” in this pricing supplement. We may appoint a different calculation agent without your consent and without notifying you.

The calculation agent will determine the redemption amount you receive at stated maturity. In addition, the calculation agent will, among other things:

·                  determine whether a market disruption event has occurred;

·                  determine if adjustments are required to the closing level of the Index under various circumstances; and

·                  if publication of the Index is discontinued, select a successor equity index or, if no successor equity index is available, determine the closing level of the Index.

All determinations made by the calculation agent will be at the sole discretion of the calculation agent and, in the absence of manifest error, will be conclusive for all purposes and binding on us and you. All percentages and other amounts resulting from any calculation with respect to the securities will be rounded at the calculation agent’s discretion. The calculation agent will have no liability for its determinations.

Appointment of Independent Calculation Experts

If a calculation or valuation described above under “—Market Disruption Events” or “—Discontinuance of the Index” contemplated to be made by the calculation agent involves the application of material discretion and is not based on information or calculation methodologies compiled or utilized by, or derived from, independent third party sources, we will appoint one or more calculation experts to confirm such calculation or valuation. Such calculation experts will be independent from us and active participants in the financial markets in the relevant jurisdiction in which futures or options contracts on the Index are traded. Calculation experts will not assume any obligation or duty to, or any relationship of agency or trust for or with, the holders of the securities or us. Holders of the securities will be entitled to rely on any valuation or calculations made by such calculation experts and such valuations or calculations will (except in the case of manifest error) be final and binding on us, the calculation agent and the holders of the securities. Calculation experts will not be responsible for good faith errors or omissions in the making of any such valuations or calculations. Calculation experts may, with the consent of us, delegate any of their obligations and functions to a third party as they deem appropriate, but acting honestly and reasonably at all times. The valuations and calculations of calculation experts will be made available to the holders of the securities upon request.

Events of Default and Acceleration

If the securities have become immediately due and payable following an event of default (as defined in the section “Description of Senior Debt Securities — Events of Default” in the accompanying prospectus) with respect to the securities, the amount payable on the securities will be equal to the redemption amount, calculated as though the date of acceleration were the calculation date.

If the securities have become immediately due and payable following an event of default, you will not be entitled to any payments with respect to the securities in addition to the redemption amount, calculated as set forth in the preceding paragraph. For more information, see “Description of Senior Debt Securities—Events of Default” beginning on page 7 of the accompanying prospectus.

PRS-21

Withholding

We or the applicable paying agent will deduct or withhold from a payment on a security any present or future tax, duty, assessment or other governmental charge that we determine is required by law or the interpretation or administration thereof to be deducted or withheld. Payments on a security will not be increased by any amount to offset such deduction or withholding.

THE S&P 500® INDEX

We obtained all information contained in this pricing supplement regarding the S&P 500® Index, including, without limitation, its make-up, method of calculation and changes in its components, from publicly available information. That information reflects the policies of, and is subject to change by, S&P Dow Jones Indices LLC (“S&P Dow Jones Indices” or “S&P”), the Index sponsor. S&P has no obligation to continue to publish, and may discontinue publication of, the S&P 500® Index at any time. Neither we nor the agent has independently verified the accuracy or completeness of any information with respect to the S&P 500® Index in connection with the offer and sale of the securities.

According to publicly available information, on July 2, 2012, The McGraw-Hill Companies, Inc., which owned the S&P Indices business, and CME Group, Inc., which is a 90% owner of the joint venture that owned the Dow Jones Indexes business, announced the launch of a new joint venture, S&P Dow Jones Indices. S&P Dow Jones Indices owns the S&P Indices business, including the S&P 500® Index, and the Dow Jones Indexes business.

General

The S&P 500® Index is published by S&P and is intended to provide an indication of the pattern of common stock price movement in the large capitalization segment of the United States equity market. The S&P 500® Index covers approximately 75% of the United States equity market by market capitalization.

The calculation of the value of the S&P 500® Index (discussed below in further detail) is based on the relative value of the aggregate Market Value (as defined below) of the common stocks of 500 companies as of a particular time compared to the aggregate average Market Value of the common stocks of 500 similar companies during the base period of the years 1941 through 1943. Historically, the “Market Value” of any S&P component stock was calculated as the product of the market price per share and the number of the then-outstanding shares of such S&P component stock. As discussed below, during March 2005, S&P began to use a new methodology to calculate the Market Value of the S&P component stocks and S&P completed its transition to the new calculation methodology during September 2005.

S&P chooses companies for inclusion in the S&P 500® Index with the aim of achieving a distribution by broad industry groupings that approximates the distribution of these groupings in the common stock population of the Standard & Poor’s Stock Guide Database, which S&P uses as an assumed model for the composition of the total market. Relevant criteria employed by S&P include the financial viability of the particular company, the market capitalization of that company ($4 billion or greater), the contribution of that company to the index’s sector balance, and the market value and trading activity of the common stock of that company. Continued index membership is not necessarily subject to these guidelines. S&P aims to minimize unnecessary turnover and each removal is determined on a case-by-case basis. Companies that substantially violate one or more of criteria for index inclusion and companies that no longer meet the inclusion criteria as a result of a merger, acquisition or significant restructuring will be considered for removal.

The S&P 500® Index does not reflect the payment of dividends on the stocks underlying it.

Computation of the S&P 500® Index

Prior to March 2005, the Market Value of a component stock was calculated as the product of the market price per share and the total number of outstanding shares of the component stock. In March 2004, S&P announced that it would transition the S&P 500® Index to float-adjusted market capitalization weights. The transition began in March 2005 and was completed in September 2005. S&P’s criteria for selecting stock for the S&P 500® Index was not changed by the shift to float adjustment. However, the adjustment affects each company’s weight in the S&P 500® Index (i.e., its Market Value). Currently, S&P calculates the S&P 500® Index based on the total float-adjusted market capitalization of each component stock, where each stock’s weight in the S&P 500® Index is proportional to its float-adjusted market value. Under float adjustment, the share counts used in calculating the S&P 500® Index reflect only those

PRS-22

shares that are available to investors, not all of a company’s outstanding shares. S&P defines three groups of shareholders whose holdings are subject to float adjustment:

·                  holdings by other publicly traded corporations, venture capital firms, private equity firms, strategic partners, or leveraged buyout groups;

·                  holdings by government entities, including all levels of government in the United States or foreign countries; and

·                  holdings by current or former officers and directors of the company, founders of the company, or family trusts of officers, directors, or founders, as well as holdings of trusts, foundations, pension funds, employee stock ownership plans, or other investment vehicles associated with and controlled by the company.

Where holdings in one of these groups exceed 10% of the outstanding shares of a company, the holdings of that group are excluded from the float-adjusted count of shares to be used in the index calculation. Treasury stock, stock options, restricted shares, equity participation units, warrants, preferred stock, convertible stock and rights are also not part of the float.

Mutual funds, investment advisory firms, pension funds, or foundations not associated with the company and investment funds in insurance companies are part of the float. Also included in the float are shares held in a trust to allow investors in countries outside the country of domicile, shares that trust beneficiaries may buy or sell without difficulty or significant additional expense beyond typical brokerage fees, and, if a company has multiple classes of stock outstanding, shares in an unlisted or non-traded class that can be converted by shareholders to a listed class without undue delay and cost.

For each stock, an investable weight factor (“IWF”) is calculated by dividing the available float shares, defined as the total shares outstanding less shares held in one or more of the three groups listed above where the group holdings exceed 10% of the outstanding shares, by the total shares outstanding. The float-adjusted index is then calculated by: dividing the sum of the IWF multiplied by both the price and the total shares outstanding for each stock by the index divisor. For companies with multiple classes of stock, S&P calculates the weighted average IWF for each stock using the proportion of the total company market capitalization of each share class as weights. In these cases, the stock price is based on one class, usually the most liquid class, and the share count is based on the total shares outstanding.

The S&P 500® Index is calculated using a base-weighted aggregate methodology: the level of the S&P 500® Index reflects the total Market Value of all the component stocks relative to the S&P 500®  base period of 1941-43. The daily calculation of the S&P 500® Index is computed by dividing the Market Value of the S&P 500®  component stocks by the index divisor.

The S&P 500® Index maintenance includes monitoring and completing the adjustments for company additions and deletions, share changes, stock splits, stock dividends and stock price adjustments due to company restructurings or spin-offs. Continuity in index values is maintained by adjusting the index divisor for all changes in the S&P 500®  constituents’ share capital after the base period of 1941-43 with the index value as of the base period set at 10. Some corporate actions, such as stock splits and stock dividends do not require index divisor adjustments because following a stock split or stock dividend, both the stock price and number of shares outstanding are adjusted by S&P so that there is no change in the Market Value of the component stock. Corporate actions (such as stock splits, stock dividends, spin-offs and rights offerings) are applied after the close of trading on the day before the ex-date. Share changes resulting from exchange offers are applied on the ex-date.

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

PRS-23

The table below summarizes the types of index maintenance adjustments and indicates whether or not an index divisor adjustment is required.

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

A large part of the S&P 500® Index maintenance process involves tracking the changes in the number of shares outstanding of each of the S&P 500® Index companies. Four times a year, on a Friday close to the end of each calendar quarter, the share totals of companies in the S&P 500® Index are updated as required by any changes in the number of shares outstanding and then the index divisor is adjusted accordingly. Changes in a company’s shares outstanding of 5.00% or more due to public offerings are made as soon as reasonably possible. Share changes due to mergers or acquisitions of publicly held companies that trade on a major exchange are implemented when the transaction occurs, even if both of the companies are not in the same headline index, and regardless of the size of the change.  All other changes of 5.00% or more (due to, for example, tender offers, Dutch auctions, voluntary exchange offers, company stock repurchases, private placements, acquisitions of private companies or non-index companies that do not trade on a major exchange, redemptions, exercise of options, warrants, conversion of preferred stock, notes, debt, equity participations, at-the-market stock offerings or other recapitalizations) are made weekly, and are announced on Fridays for implementation after the close of trading on the following Friday. Changes of less than 5.00% are accumulated and made quarterly on the third Friday of March, June, September, and December, and are usually announced two to five days prior. If a change in a company’s shares outstanding of 5.00%

PRS-24

or more causes a company’s IWF to change by five percentage points or more, the IWF is updated at the same time as the share change. IWF changes resulting from partial tender offers are considered on a case-by-case basis.

USE OF PROCEEDS AND HEDGING

The net proceeds from the sale of the securities will be used as described under “Use of Proceeds” in the accompanying prospectus supplement and the prospectus and to hedge our market risks associated with our obligation to pay at maturity the redemption amount of the securities.

We may hedge our obligations under the securities by, among other things, purchasing securities, futures, options or other derivative instruments with returns linked or related to changes in the value of the Index and/or securities underlying the Index, 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 securities. 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 securities declines.

We expect to hedge our obligations under the securities 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 securities 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 securities from time to time. See “Risk Factors—The Estimated Value of the Securities Is Not An Indication Of The Price, If Any, At Which Wells Fargo Securities Or Any Other Person May Be Willing To Buy The Securities From You In The Secondary Market” and “—Our Economic Interests And Those of Any Dealer Participating In The Offering Of Securities Will Potentially Be Adverse To Your Interests” in this pricing supplement for a discussion of these adverse effects.

PRS-28

THE ESTIMATED VALUE OF THE SECURITIES

The estimated value of the securities set forth on the cover of this pricing supplement is equal to the sum of the values of the following hypothetical components: (1) a fixed-income debt component with the same maturity as the securities, valued using our internal funding rate for structured debt described below, and (2) the derivative or derivatives underlying the economic terms of the securities. The estimated value does not represent a minimum price at which Wells Fargo Securities or any other person would be willing to buy your securities in any secondary market (if any exists) at any time. The internal funding rate used in the determination of the Bank’s 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 securities as well as the higher issuance, operational and ongoing liability management costs of the securities in comparison to those costs for our conventional fixed-rate debt. For additional information, see “Risk Factors—Our Estimated Value Was Not Determined By Reference To Credit Spreads For Our Conventional Fixed-Rate Debt” in this pricing supplement. The value of the derivative or derivatives underlying the economic terms of the securities 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 estimated value of the securities was determined when the terms of the securities were set based on market conditions and other relevant factors and assumptions existing at that time. See “Risk Factors—Our Estimated Value Does Not Represent Future Values Of The Securities And May Differ From Others’ Estimates” in this pricing supplement.

The Bank’s estimated value of the securities is lower than the principal amount of the securities because costs associated with selling, structuring and hedging the securities are included in the principal amount of the securities. These costs include the selling commissions paid to 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 securities and the estimated cost of hedging our obligations under the securities. 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 securities. See “Risk Factors—Our Estimated Value of the Securities Is Lower Than The Principal Amount Of The Securities” in this pricing supplement.

PRS-29

SUPPLEMENTAL PLAN OF DISTRIBUTION

The securities are being purchased by Wells Fargo Securities as principal, pursuant to a distribution agreement between Wells Fargo Securities and us. We have agreed to pay certain of Wells Fargo Securities’ expenses in connection with the offering of the securities.

From time to time, Wells Fargo Securities and its affiliates have engaged, and in the future may engage, in transactions with and performance of services for us for which they have been, and may be, paid customary fees. In particular, Wells Fargo Securities or one of its affiliates may be our swap counterparty for a hedge relating to our obligations under the securities.

In the future, Wells Fargo Securities and its affiliates may repurchase and resell the offered securities in market-making transactions, with resales being made at prices related to prevailing market prices at the time of resale or otherwise. Unless you are informed otherwise in the confirmation of sale, this pricing supplement and the accompanying prospectus supplement and prospectus are being used in connection with the initial distribution of the securities and not in a market-making transaction.

Wells Fargo Securities has committed to purchase all of these securities in the initial public offering of the securities if any are purchased.

Wells Fargo Securities proposes to offer the securities to certain securities dealers, including securities dealers acting as custodians, at the principal amount of the securities less a concession not in excess of $1.40 per security. Such securities dealers may include WFA (the trade name of the retail brokerage business of Wells Fargo Clearing Services, LLC and Wells Fargo Advisors Financial Network, LLC, each an affiliate of Wells Fargo Securities).

The principal amount of the securities includes the underwriting discount received by Wells Fargo Securities and the projected profit that our hedge counterparties expect to realize in consideration for assuming the risks inherent in hedging our obligations under the securities. We expect to hedge our obligations through an affiliate of Wells Fargo Securities, one of our affiliates and/or another unaffiliated counterparty. Because hedging our obligations entails risks and may be influenced by market forces beyond the counterparties’ control, such hedging may result in a profit that is more or less than expected, or could result in a loss. The underwriting discount and projected profit of our hedge counterparties reduce the economic terms of the securities. In addition, the fact that the principal amount includes these items is expected to adversely affect the secondary market prices of the securities. These secondary market prices are also likely to be reduced by the cost of unwinding the related hedging transaction. See “Use of Proceeds and Hedging” in this pricing supplement.

The securities are a new issue of securities with no established trading market. The securities will not be listed on a national securities exchange. Wells Fargo Securities may make a market for the securities, as applicable laws and regulations permit, but is not obligated to do so and may discontinue making a market at any time without notice. No assurance can be given as to the liquidity of any trading market for the securities.

We will deliver the securities against payment therefor in New York, New York on January 5, 2018, which is the fourth scheduled business day following the date of this pricing supplement and of the pricing of the securities. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade securities on any date prior to two business days before delivery will be required, by virtue of the fact that the securities are expected to settle in four business days (T + 4), to specify alternative settlement arrangements to prevent a failed settlement.

Settlement for the securities will be made in immediately available funds. The securities will be in the Same Day Funds Settlement System at DTC and, to the extent any secondary market trading in the securities is effected through the facilities of such depositary, such trades will be settled in immediately available funds.

Canadian Imperial Bank of Commerce has agreed to indemnify Wells Fargo Securities against certain liabilities, including liabilities under the Securities Act of 1933.

No action has been or will be taken by Canadian Imperial Bank of Commerce, Wells Fargo Securities or any broker-dealer affiliates of either Canadian Imperial Bank of Commerce or Wells Fargo Securities that would permit a public offering of the securities or possession or distribution of this pricing supplement or the accompanying prospectus and prospectus supplement in any jurisdiction, other than the United States, where action for that purpose is required. No offers, sales or deliveries of the securities, or distribution of

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following discussion supplements the discussion in the section called “Material Income Tax Consequences—United States Taxation” in the accompanying prospectus, and is subject to the limitations and exceptions set forth therein. Capitalized terms used in this section without definition shall have the respective meanings given such terms in the accompanying prospectus.

The following summary describes certain U.S. federal income tax consequences relevant to the purchase, ownership, and disposition of the securities. This summary applies only to holders that acquire their securities in this offering for a price equal to the principal amount, which we understand will be at par, and hold such securities as capital assets, within the meaning of Section 1221 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). This summary does not apply to any holder that is subject to special rules, such as:

·                  a dealer in securities,

·                  a trader in securities that elects to use a mark-to-market method of accounting for your securities holdings,

·                  a bank,

·                  a life insurance company,

·                  a tax-exempt organization,

·                  a person that owns the securities as part of a straddle or a hedging or conversion transaction for tax purposes,

·                  a person that purchases or sells the securities as part of a wash sale for tax purposes,

·                  a regulated investment company or real estate investment trust,

·                  a U.S. holder (as defined in the accompanying prospectus) whose functional currency for tax purposes is not the U.S. dollar,

·                  a U.S. holder subject to the alternative minimum tax, or

·                  U.S. expatriates.

This discussion is based upon current provisions of the Code, existing and proposed Treasury Regulations thereunder, current administrative rulings, judicial decisions and other applicable authorities. All of the foregoing are subject to change, which change may apply retroactively and could affect the continued validity of this summary. This summary does not describe any tax consequences arising under the laws of any state, locality or taxing jurisdiction other than the U.S. federal government. This discussion also does not purport to be a complete analysis of all tax considerations relating to the securities.

You should consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the securities in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.

If a partnership holds the securities, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the tax treatment of the partnership. You should consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the securities if you are a partner in a partnership holding the securities.

PRS-33

General

We will not attempt to ascertain whether any of the issuers of the shares that constitute the underlying Index (the shares hereafter referred to as “Underlying Shares”) should be treated as a passive foreign investment company within the meaning of section 1297 of the Code (a “PFIC”). If any of the issuers of Underlying Shares were so treated, certain adverse U.S. federal income tax consequences might apply to a U.S. holder (as defined below) upon the sale, exchange or retirement of the securities. Potential investors considering an investment in the securities should refer to information filed with the SEC or another governmental authority by the issuers of Underlying Shares and consult their tax advisers regarding the possible consequences to them if any issuer of Underlying Shares is or becomes a PFIC.

As the law applicable to the U.S. federal taxation of instruments such as the securities is technical and complex, the discussion below necessarily represents only a general summary. The U.S. federal income tax consequences of your investment in the securities are uncertain. No statutory, judicial or administrative authority directly discusses how the securities should be treated for U.S. federal income tax purposes.

In the opinion of our counsel, Mayer Brown LLP, it would be generally reasonable to treat the securities as pre-paid cash-settled derivative contracts. The terms of the securities will provide that you agree to treat the securities in this manner for all U.S. federal income tax purposes.

Unless otherwise stated, the following discussion is based on the characterization described above. The discussion in this section reflects the opinion of Mayer Brown that there is a significant possibility of a significant loss of principal on an investment in the securities.

Tax Consequences to U.S. Holders

Subject to the discussion below of Section 1260 of the Code, if you are a U.S. holder, you should generally recognize capital gain or loss upon the sale, exchange or payment on maturity in an amount equal to the difference between the amount you receive at such time and your tax basis in the securities. In general, your tax basis in the securities will be equal to the price you paid for them. Such gain or loss should generally be short-term capital gain or loss. Capital gain recognized by an individual U.S. holder is generally taxed at preferential rates where the property is held for more than one year. The deductibility of capital losses is subject to limitations.

The constructive ownership rules of Section 1260 of the Code could possibly apply to securities that have a term in excess of one year and reference a “pass-thru entity” (as defined in Section 1260(c)(2) of the Code). Examples of “pass-thru entities” include (but are not limited to) regulated investment companies (e.g., most exchange-traded funds), real estate investment trusts, passive foreign investment companies and partnerships. It is not entirely clear how Section 1260 applies to an Index that is wholly or partially comprised of “pass-thru entities.” We generally do not intend to make an inquiry as to whether the Index contains any “pass-thru entities”, and it is possible that securities for which the Index contains a “pass-thru entity” could be wholly or partially subject to Section 1260 of the Code. If the securities were subject to Section 1260 of the Code, then, among other consequences, all or a portion of any long-term capital gain that you realize upon the sale, redemption or stated maturity of the securities would be recharacterized as ordinary income (and you would be subject to an interest charge on deferred tax liability with respect to such recharacterized amount) to the extent that such capital gain exceeds the amount of long-term capital gain that you would have realized had you purchased the actual number of interests in the Index on the date that you purchased the securities and sold those interests on the date of the sale, redemption or stated maturity of the securities. Accordingly, if the Index contains a “pass-thru entity,” you should consult your tax advisor about the potential application of Section 1260 of the Code to the securities.

Possible Alternative Tax Treatments of an Investment in the Securities

As noted above, there is no judicial or administrative authority discussing how the securities should be treated for U.S. federal income tax purposes. Therefore, other treatments would also be reasonable and the Internal Revenue Service might assert that treatment other than that described above is more appropriate.

In 2008, U.S. Treasury Department and the Internal Revenue Service released a notice that may affect the taxation of holders of the securities. According to the notice, the Internal Revenue Service and the U.S. Treasury are actively considering whether the holder of an instrument such as the securities should be required to accrue ordinary income on a current basis, and they are seeking taxpayer

PRS-34

comments on the subject. The notice also states that the Internal Revenue Service and the Treasury Department are also considering other relevant issues, including whether gain or loss from such instruments should be treated as ordinary or capital and whether the special “constructive ownership rules” of Section 1260 of the Code might be applied to such instruments. Similarly, the Internal Revenue Service and the Treasury Department have current projects open with regard to the tax treatment of pre-paid forward contracts and contingent notional principal contracts. While it is not clear whether the securities would be viewed as similar to instruments discussed in such notice, it is possible that any future guidance could materially and adversely affect the tax consequences of an investment in the securities, possibly with retroactive effect.

Similarly, the Internal Revenue Service might assert, and a possible alternative treatment with respect to the securities would be, to treat the securities as a single debt instrument. Such a debt instrument may be subject to the special tax rules governing contingent payment debt instruments.

If the securities are subject to such special rules applicable to contingent payment debt instruments, the amount of interest U.S. holders are required to take into account for each accrual period will be determined by constructing a projected payment schedule for the securities and applying rules similar to those for accruing “original issue discount” or OID on a hypothetical noncontingent debt instrument with that projected payment schedule. In addition to accruing interest income in accordance with the comparable yield, a U.S. holder will be required to make adjustments if the actual amounts that a holder receives in any taxable year differs from the projected payment schedule. These rules could possibly have the effect of requiring U.S. holders to include amounts in income in respect of the securities prior to receipt of cash attributable to that income.

U.S. holders will recognize gain or loss on the sale, redemption or maturity of securities treated as contingent payment debt instruments in an amount equal to the difference, if any, between the amount of cash received at that time and their adjusted basis in the securities. In general, a U.S. holder’s adjusted basis in such securities will equal the amount the holder paid for the securities, increased by the amount of interest that was previously accrued with respect to the securities. Any such gain will generally be ordinary income and any such loss that will generally be ordinary loss to the extent the interest included as income in the current or previous taxable years, and thereafter will be capital loss.

Information Reporting and Backup Withholding

The proceeds received from a sale, exchange or retirement of the securities may be subject to information reporting and, if the holder fails to provide certain identifying information (such as an accurate taxpayer identification number in the case of a U.S. holder) or meet certain other conditions, may also be subject to backup withholding at the rate specified in the Code. A non-U.S. holder (or financial institution holding the securities on behalf of the non-U.S. holder) that provides the applicable withholding agent with the appropriate Internal Revenue Service Form W-8 will generally establish an exemption from backup withholding. Amounts withheld under the backup withholding rules are not additional taxes and may be refunded or credited against the holder’s U.S. federal income tax liability, provided the relevant information is timely furnished to the Internal Revenue Service.

You are urged to consult your tax advisors concerning the significance, and the potential impact, of the above considerations.

Additional Information for U.S. Holders.

For information regarding backup withholding and information reporting considerations with respect to the securities, please see the discussion under “Material Income Tax Consequences—United States Taxation—U.S. Backup Withholding and Information Reporting” in the accompanying prospectus.

Tax Consequences to Non-U.S. Holders

For purposes of this discussion, the term “non-U.S. holder” means a beneficial owner of a security that is not a partnership or other entity treated as a partnership and is not a U.S. holder. If you are a non-U.S. holder, you generally will not be subject to U.S. federal income or withholding tax for amounts paid in respect of the securities, provided that the payment is not effectively connected with your conduct of a U.S. trade or business. Notwithstanding the foregoing, gain from the sale or exchange of the securities or their settlement at maturity may be subject to U.S. federal income tax if you are a nonresident alien individual and are present in the U.S. for 183 days or more during the taxable year of the settlement at maturity, sale or exchange and certain other conditions are satisfied.

PRS-35

If you are engaged in the conduct of a trade or business within the U.S. and if gain realized on the settlement at maturity, sale or exchange of the securities, is 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.), you generally will be subject to U.S. federal income tax on such gain on a net income basis in the same manner as if you were a U.S. holder as described under the heading “Tax Consequences to U.S. Holders,” above. In addition, non-U.S. holders that are foreign corporations, 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 their earnings and profits that are withdrawn from the U.S. for the taxable year that are effectively connected with their conduct of a trade or business in the U.S., subject to certain adjustments.

Notwithstanding the above, if we determine that there is a material risk that we will be required to withhold on any payments on the securities, we may withhold on any such payment to a non-U.S. holder at a 30% rate, unless such non-U.S. holder has provided to us (i) a valid Internal Revenue Service Form W-8ECI or (ii) a valid Internal Revenue Service Form W-8BEN or Internal Revenue Service Form W-8BEN-E claiming tax treaty benefits that reduce or eliminate withholding. If we elect to withhold and such non-U.S. holder has provided us with a valid Internal Revenue Service Form W-8BEN or Internal Revenue Service Form W-8BEN-E claiming tax treaty benefits that reduce or eliminate withholding, we may nevertheless withhold up to 30% on any payments if there is any possible characterization of the payments that would not be exempt from withholding under the treaty.

Section 871(m) of the Code and Treasury regulations promulgated thereunder (“Section 871(m)”) generally impose a 30% withholding tax on dividend equivalents paid or deemed paid to non-U.S. holders with respect to certain financial instruments linked to U.S. equities or indices that include U.S. equities (such equities and indices, “U.S. Underlying Equities”) other than qualified indices. Section 871(m) generally applies to instruments that substantially replicate the economic performance of one or more U.S. Underlying Equities, as determined upon issuance, based on tests set forth in the applicable Treasury regulations (a “Specified Security”). Specifically, and subject to the pre-2019 exemption described in the next paragraph, Section 871(m) will apply if, at issuance, a financial instrument either meets (i) a “delta” test, if it is a “simple” contract, or (ii) a “substantial equivalence” test, if it is a “complex” contract. Section 871(m) provides certain exceptions to this withholding regime, in particular for instruments linked to certain broad-based indices that meet requirements set forth in the applicable Treasury regulations as well as securities that track such indices.

The U.S. Treasury Department has issued regulations under Section 871(m) that exempt financial instruments issued prior to 2019 that are not “delta-one.” Based on the terms of the securities and representations provided by us, our counsel is of the opinion that the securities should not be Specified Securities subject to withholding tax under Section 871(m).

A determination that the securities are not subject to Section 871(m) is not binding on the IRS, and the IRS may disagree with this treatment. Moreover, Section 871(m) is complex and its application may depend on your particular circumstances. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities.

As discussed above, alternative characterizations of the securities 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 securities to become subject to withholding tax, we will withhold tax at the applicable statutory rate. Additionally, as discussed above, the Internal Revenue Service has indicated that it is considering whether income in respect of instruments such as the securities should be subject to withholding tax. Prospective non-U.S. holders of the securities should consult their own tax advisors in this regard.

The gross estate of a non-U.S. holder domiciled outside the United States includes only property situated in the United States. A security may be subject to U.S. federal estate tax if an individual non-U.S. holder holds the security at the time of his or her death. Individual non-U.S. holders should consult their tax advisors regarding the U.S. federal estate tax consequences of holding the securities at death.

Additional Information for Investors

For information regarding the applicability of FATCA to the securities, please see the discussion under “Material Income Tax Consequences—United States Taxation—FATCA Withholding” in the accompanying prospectus. FATCA may impose a 30% withholding tax on payments of gross proceeds from the sale, exchange or redemption of property that gives rise to U.S.-source dividends or interest. The Internal Revenue Service recently announced in published guidance its intent to amend the regulations to extend the effective date of withholding on gross proceeds to 1 January 2019. Similarly, the Internal Revenue Service announced its intention to delay the effective date of withholding tax on “foreign passthru payments” to the later of 1 January 2019 or the date of publication of final U.S. Treasury regulations defining such term.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

In the opinion of Blake, Cassels & Graydon LLP, our Canadian tax counsel, the following summary describes the principal Canadian federal income tax considerations under the Income Tax Act (Canada) (the “Canadian Tax Act”) generally applicable at the date hereof to an investor who acquires beneficial ownership of a security pursuant to this pricing supplement and who for the purposes of the Canadian Tax Act and at all relevant times: (a) is neither resident nor deemed to be resident in Canada; (b) deals at arm’s length with the Issuer and any transferee resident (or deemed to be resident) in Canada to whom the investor disposes of the security; (c) does not use or hold the security in, or in the course of, carrying on a business in Canada; (d) is entitled to receive all payments (including any interest and principal) made on the security, and (e) is not a, and deals at arm’s length with any, “specified shareholder” of the Issuer for purposes of the thin capitalization rules in the Canadian Tax Act (a “Non-Resident Holder”). A “specified shareholder” for these purposes generally includes a person who (either alone or together with persons with whom that person is not dealing at arm’s length for the purposes of the Canadian Tax Act) owns or has the right to acquire or control or is otherwise deemed to own 25% or more of the Issuer’s shares determined on a votes or fair market value basis. Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

This summary is supplemental to and should be read together with the description of material Canadian federal income tax considerations relevant to a Non-Resident Holder owning securities under “Material Income Tax Consequences—Canadian Taxation” in the accompanying prospectus and a Non-Resident Holder should carefully read that description as well.

This summary is of a general nature only and is not intended to be, nor should it be construed to be, legal or tax advice to any particular Non-Resident Holder. Non-Resident Holders are advised to consult with their own tax advisors with respect to their particular circumstances.

Based on Canadian tax counsel’s understanding of the Canada Revenue Agency’s administrative policies, and having regard to the terms of the securities, interest payable on the securities should not be considered to be “participating debt interest” as defined in the Canadian Tax Act and accordingly, a Non-Resident Holder should not be subject to Canadian non-resident withholding tax in respect of amounts paid or credited or deemed to have been paid or credited by the Issuer on a security as, on account of or in lieu of payment of, or in satisfaction of, interest.

Non-Resident Holders should consult their own tax advisors regarding the consequences to them of a disposition of the securities to a person with whom they are not dealing at arm’s length for purposes of the Canadian Tax Act.

VALIDITY OF THE SECURITIES

In the opinion of Blake, Cassels & Graydon LLP, as Canadian counsel to the Bank, the issue and sale of the securities has been duly authorized by all necessary corporate action of the Bank in conformity with the indenture, and when the securities have been duly executed, authenticated and issued in accordance with the indenture, the securities will be validly issued and, to the extent validity of the securities is a matter governed by the laws of the Province of Ontario or the federal laws of Canada applicable therein, will be valid obligations of the Bank, subject to applicable bankruptcy, insolvency and other laws of general application affecting creditors’ rights, equitable principles, and subject to limitations as to the currency in which judgments in Canada may be rendered, as prescribed by the Currency Act (Canada), and subject to any bail-in conversion requirements under the Canada Deposit Insurance Corporation Act (Canada). This opinion is given as of the date hereof and is limited to the laws of the Province of Ontario and the federal laws of Canada applicable therein. In addition, this opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the indenture and the genuineness of signature, and to such counsel’s reliance on the Bank and other sources as to certain factual matters, all as stated in the opinion letter of such counsel dated February 27, 2017, which has been filed as Exhibit 5.2 to the Bank’s Registration Statement on Form F-3 filed with the SEC on February 27, 2017.

In the opinion of Mayer Brown LLP, when the securities have been duly completed in accordance with the indenture and issued and sold as contemplated by the prospectus supplement and the prospectus, the securities will constitute valid and binding obligations of the Bank, entitled to the benefits of the indenture, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. This opinion is given as of the date hereof and is limited to the laws of the State of New York. This opinion is subject to customary assumptions about the trustee’s authorization, execution and delivery of the indenture and such counsel’s reliance on the Bank and other sources as to certain factual matters, all as stated in the legal opinion dated February 27, 2017, which has been filed as Exhibit 5.1 to the Bank’s Registration Statement on Form F-3 filed with the SEC on February 27, 2017.
