Summary

The STEP Income Securities® Linked to the Common Stock of JPMorgan Chase & Co., due November , 2018 (the “notes”) are our senior unsecured debt securities. The notes are not guaranteed or insured by the Canada Deposit Insurance Corporation, the U.S. Federal Deposit Insurance Corporation or any other governmental agency of the United States, Canada or any other jurisdiction or secured by collateral. The notes will rank equally with all of our other unsecured and unsubordinated debt. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of CIBC. The notes provide quarterly interest payments. Additionally, if the Ending Value of the Market Measure, which is the common stock of JPMorgan Chase & Co. (the “Underlying Stock”), is at or above the Step Level, the notes will also provide a payment of [$0.10 to $0.50] per unit at maturity. If the Ending Value is less than the Step Level, the Redemption Amount will not be greater than your principal amount. If the Ending Value is less than the Starting Value, the Redemption Amount will be less than the principal amount of your notes, and may be as low as zero. Any payments on the notes will be calculated based on the $10 principal amount per unit and will depend on the performance of the Underlying Stock, subject to our credit risk. See “Terms of the Notes” below.

The economic terms of the notes (including the Step Payment) are based on our internal funding rate, which is the rate we would pay to borrow funds through the issuance of market-linked notes, and the economic terms of certain related hedging arrangements. Our internal funding rate is typically lower than the rate we would pay when we issue conventional fixed rate debt securities. This difference in funding rate, as well as the underwriting discount and the hedging related charge described below, will reduce the economic terms of the notes to you and the initial estimated value of the notes on the pricing date. Due to these factors, the public offering price you pay to purchase the notes will be greater than the initial estimated value of the notes.

On the cover page of this term sheet, we have provided the initial estimated value range for the notes. This initial estimated value range was determined based on our pricing models. The initial estimated value as of the pricing date will be based on our internal funding rate on the pricing date, market conditions and other relevant factors existing at that time, and our assumptions about market parameters. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-11.

Hypothetical Payments at Maturity

The following examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical payments on the notes. The actual amount you receive and the resulting return will depend on the actual Starting Value, Threshold Value, Ending Value, Step Level, Step Payment, and the term of your investment. The following examples do not take into account any tax consequences from investing in the notes. These examples are based on:

1) a hypothetical Starting Value of 100.00;

2) a hypothetical Threshold Value of 100.00 (100.00% of the hypothetical Starting Value);

3) a hypothetical Step Level of 106.00 (106.00% of the hypothetical Starting Value);

4) a hypothetical Step Payment of $0.30 per unit (the midpoint of the Step Payment range of [$0.10 to $0.50] per unit);

5) an expected term of the notes of approximately one year and one week; and

6) the interest rate of 6.00% per year.

The hypothetical Starting Value of 100.00 used in these examples has been chosen for illustrative purposes only, and does not represent a likely actual Starting Value of the Underlying Stock. For recent actual prices of the Underlying Stock, see “The Underlying Stock” section below. In addition, all payments on the notes are subject to issuer credit risk.

Example 1

The Ending Value is 115.00 (115.00% of the Starting Value)

The Ending Value is greater than the Step Level. Consequently, in addition to the quarterly interest payments, you will receive on the maturity date the principal amount plus the Step Payment of $0.30 per unit. The Redemption Amount will therefore be equal to $10.30 per unit ($10.00 plus the Step Payment of $0.30 per unit).

Example 2

The Ending Value is 105.00 (105.00% of the Starting Value)

The Ending Value is greater than the Starting Value and the Threshold Value but less than the Step Level. Consequently, you will receive the quarterly interest payments, but you will not receive the Step Payment on the maturity date. The Redemption Amount will therefore be equal to the principal amount of $10.00 per unit.

Example 3

The Ending Value is 70.00 (70.00% of the Starting Value)

The Ending Value is less than the Starting Value and the Threshold Value. Consequently, you will receive the quarterly interest payments, but you will not receive the Step Payment on the maturity date, and you will participate on a 1-for-1 basis in the decrease in the price of the Underlying Stock. The Redemption Amount per unit will equal:

On the maturity date, you will receive a Redemption Amount equal to $7.00 per unit.

Risk Factors

There are important differences between the notes and a conventional debt security. An investment in the notes involves significant risks, including those listed below. You should carefully review the more detailed explanation of risks relating to the notes in the “Risk Factors” sections beginning on page PS-6 of product supplement STEPS-1, page S-1 of the prospectus supplement, and page 1 of the prospectus identified above. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

§ Depending on the performance of the Underlying Stock as measured shortly before the maturity date, your investment may result in a loss; there is no guaranteed return of principal.

§ You will not receive a Step Payment at maturity unless the Ending Value is greater than or equal to the Step Level.

§ Your return on the notes may be less than the yield you could earn by owning a conventional fixed or floating rate debt security of comparable maturity.

§ Your investment return is limited to the return represented by the periodic interest payments over the term of the notes and the Step Payment, if any, and may be less than a comparable investment directly in the Underlying Stock.

§ Payments on the notes are subject to our credit risk, and actual or perceived changes in our creditworthiness are expected to affect the value of the notes. If we become insolvent or are unable to pay our obligations, you may lose your entire investment.

§ Our initial estimated value of the notes will be lower than the public offering price of the notes. The public offering price of the notes will exceed our initial estimated value because costs associated with selling and structuring the notes, as well as hedging the notes, all as further described in “Structuring the Notes” on page TS-11, are included in the public offering price of the notes.

§ Our initial estimated value does not represent future values of the notes and may differ from others’ estimates. Our initial estimated value is only an estimate, which will be determined by reference to our internal pricing models when the terms of the notes are set. This estimated value will be based on market conditions and other relevant factors existing at that time, our internal funding rate on the pricing date 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 notes that are greater or less than our initial estimated value. In addition, market conditions and other relevant factors in the future may change, and any assumptions may prove to be incorrect. On future dates, the market value of the notes could change significantly based on, among other things, changes in market conditions, including the value of the Market Measure, our creditworthiness, interest rate movements and other relevant factors, which may impact the price at which MLPF&S or any other party would be willing to buy notes from you in any secondary market transactions. Our estimated value does not represent a minimum price at which MLPF&S or any other party would be willing to buy your notes in any secondary market (if any exists) at any time.

§ Our initial estimated value of the notes will not be determined by reference to credit spreads for our conventional fixed-rate debt. The internal funding rate to be used in the determination of our initial estimated value of the notes generally represents a discount from the credit spreads for our conventional fixed-rate debt. The discount is based on, among other things, our view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. If we were to use the interest rate implied by our conventional fixed-rate debt, we would expect the economic terms of the notes to be more favorable to you. Consequently, our use of an internal funding rate for market-linked notes would have an adverse effect on the economic terms of the notes, the initial estimated value of the notes on the pricing date, and any secondary market prices of the notes.

§ A trading market is not expected to develop for the notes. Neither we nor MLPF&S is obligated to make a market for, or to repurchase, the notes. There is no assurance that any party will be willing to purchase your notes at any price in any secondary market.

§ Our business, hedging and trading activities, and those of MLPF&S and our respective affiliates (including trades in shares of the Underlying Stock) and any hedging and trading activities we, MLPF&S or our respective affiliates engage in for our clients’ accounts, may affect the market value and return of the notes and may create conflicts of interest with you.

§ The Underlying Company will have no obligations relating to the notes, and neither we nor MLPF&S will perform any due diligence procedures with respect to the Underlying Company in connection with this offering.

§ You will have no rights of a holder of the Underlying Stock, and you will not be entitled to receive any shares of the Underlying Stock or dividends or other distributions by the Underlying Company.

§ While we, MLPF&S or our respective affiliates may from time to time own securities of the Underlying Company, we, MLPF&S or our respective affiliates do not control the Underlying Company, and have not verified any disclosure made by the Underlying Company.

§ The Redemption Amount will not be adjusted for all corporate events that could affect the Underlying Stock. See “Description of the Notes—Anti-Dilution Adjustments” beginning on page PS-21 of product supplement STEPS-1.

§ There may be potential conflicts of interest involving the calculation agent, which is MLPF&S. We have the right to appoint and remove the calculation agent.

Supplement to the Plan of Distribution

Under our distribution agreement with MLPF&S, MLPF&S will purchase the notes from us as principal at the public offering price indicated on the cover of this term sheet, less the indicated underwriting discount.

We may deliver the notes against payment therefor in New York, New York on a date that is greater than two business days following the pricing date. 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, if the initial settlement of the notes occurs more than two business days from the pricing date, purchasers who wish to trade the notes more than two business days prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

The notes will not be listed on any securities exchange. In the original offering of the notes, the notes will be sold in minimum investment amounts of 100 units. If you place an order to purchase the notes, you are consenting to MLPF&S acting as a principal in effecting the transaction for your account.

MLPF&S may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices, and these prices will include MLPF&S’s trading commissions and mark-ups. MLPF&S may act as principal or agent in these market-making transactions; however, it is not obligated to engage in any such transactions. At MLPF&S’s discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes. Any price offered by MLPF&S for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Underlying Stock and the remaining term of the notes. However, none of us, MLPF&S, or any of our respective affiliates is obligated to purchase your notes at any price or at any time, and we cannot assure you that we, MLPF&S or any of our respective affiliates will purchase your notes at a price that equals or exceeds the initial estimated value of the notes.

The value of the notes shown on your account statement will be based on MLPF&S’s estimate of the value of the notes if MLPF&S or another of its affiliates were to make a market in the notes, which it is not obligated to do. That estimate will be based upon the price that MLPF&S may pay for the notes in light of then-prevailing market conditions, and other considerations, as mentioned above, and will include transaction costs. At certain times, this price may be higher than or lower than the initial estimated value of the notes.

The distribution of the Note Prospectus in connection with these offers or sales will be solely for the purpose of providing investors with the description of the terms of the notes that was made available to investors in connection with their initial offering. Secondary market investors should not, and will not be authorized to, rely on the Note Prospectus for information regarding CIBC or for any purpose other than that described in the immediately preceding sentence.

An investor’s household, as referenced on the cover of this term sheet, will generally include accounts held by any of the following, as determined by MLPF&S in its discretion and acting in good faith based upon information then available to MLPF&S:

· the investor’s spouse (including a domestic partner), siblings, parents, grandparents, spouse’s parents, children and grandchildren, but excluding accounts held by aunts, uncles, cousins, nieces, nephews or any other family relationship not directly above or below the individual investor;

· a family investment vehicle, including foundations, limited partnerships and personal holding companies, but only if the beneficial owners of the vehicle consist solely of the investor or members of the investor’s household as described above; and

· a trust where the grantors and/or beneficiaries of the trust consist solely of the investor or members of the investor’s household as described above; provided that, purchases of the notes by a trust generally cannot be aggregated together with any purchases made by a trustee’s personal account.

Purchases in retirement accounts will not be considered part of the same household as an individual investor’s personal or other non-retirement account, except for individual retirement accounts (“IRAs”), simplified employee pension plans (“SEPs”), savings incentive match plan for employees (“SIMPLEs”), and single-participant or owners only accounts (i.e., retirement accounts held by self-employed individuals, business owners or partners with no employees other than their spouses).

Please contact your Merrill Lynch financial advisor if you have any questions about the application of these provisions to your specific circumstances or think you are eligible.

Structuring the Notes

The notes are our debt securities, the return on which is linked to the performance of the Underlying Stock. As is the case for all of our debt securities, including our market-linked notes, the economic terms of the notes reflect our actual or perceived creditworthiness at the time of pricing. The internal funding rate we use in pricing the market-linked notes is typically lower than the rate we would pay when we issue conventional fixed-rate debt securities of comparable maturity. This difference is based on, among other things, our view of the funding value of the notes as well as the higher issuance, operational and ongoing liability management costs of the notes in comparison to those costs for our conventional fixed-rate debt. This generally relatively lower internal funding rate, which is reflected in the economic terms of the notes, along with the fees and charges associated with market-linked notes, typically results in the initial estimated value of the notes on the pricing date being less than their public offering price.

Payments on the notes, including the interest payments on the notes and the Redemption Amount, will be calculated based on the $10 principal amount per unit. The Redemption Amount will depend on the performance of the Underlying Stock. We are also required to make the interest payments on the notes. In order to meet these payment obligations, at the time we issue the notes, we may choose to enter into certain hedging arrangements (which may include call options, put options or other derivatives) with MLPF&S or one of its affiliates. The terms of these hedging arrangements are determined by seeking bids from market participants, including MLPF&S and its affiliates, and take into account a number of factors, including our creditworthiness, interest rate movements, the volatility of the Underlying Stock, the tenor of the notes and the tenor of the hedging arrangements. The economic terms of the notes and their initial estimated value depend in part on the terms of these hedging arrangements.

MLPF&S has advised us that the hedging arrangements will include a hedging related charge of approximately $0.075 per unit, reflecting an estimated profit to be credited to MLPF&S from these transactions. Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by MLPF&S or any third party hedge providers.

Summary of 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 a purchaser who acquires beneficial ownership of a note pursuant to this term sheet and who for the purposes of the Canadian Tax Act and the regulations thereto and at all relevant times: (a) is neither resident nor deemed to be resident in Canada; (b) deals at arm’s length with CIBC and any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of the note; (c) does not use or hold and is not deemed to use or hold the note 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 note; and (e) is not a, and deals at arm’s length with any, “specified shareholder” of CIBC 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 CIBC’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 notes under “Material Income Tax Consequences—Canadian Taxation” in the accompanying prospectus and a Non-Resident Holder should carefully read that description as well.

Based on our Canadian tax counsel’s understanding of the Canada Revenue Agency’s administrative policies, and having regard to the terms of the notes, interest payable on the notes 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 CIBC on a note 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 notes to a person with whom they are not dealing at arm’s length for purposes of the Canadian Tax Act.

Summary of U.S. Federal Income Tax Consequences

The following discussion is a brief summary of the material U.S. federal income consequences relating to an investment in the notes. The following summary is not complete and is both qualified and supplemented by, or in some cases supplements, the discussion entitled “U.S. Federal Income Tax Summary” beginning on page PS-34 of product supplement STEPS-1, which you should carefully review prior to investing in the notes.

The U.S. federal income tax consequences of your investment in the notes are uncertain. No statutory, judicial or administrative authority directly discusses how the notes should be treated for U.S. federal income tax purposes. In the opinion of our tax counsel Mayer Brown LLP, it would generally be reasonable to treat the notes as income-bearing single financial contracts. Pursuant to the terms of the notes, you agree to treat the notes in this manner for all U.S. federal income tax purposes. If your notes are so treated, you should generally recognize capital gain or loss upon the sale, exchange, redemption or payment on maturity in an amount equal to the difference between the amount you receive at such time, including any Step Payment, and the amount that you paid for your notes. Such gain or loss should generally be long-term capital gain or loss if you have held your notes for more than one year.

If you are a U.S. person, we will report the periodic interest payments to you as ordinary income.

If you are a non-U.S. person, we do not expect to withhold any U.S. federal income tax from the periodic interest payments. Regarding the discussion in the product supplement STEPS-1 with respect to a dividend equivalent payment made with respect to an equity-linked instrument under the section entitled Non-U.S. Holders, the regulations under Section 871(m) exempt instruments issued prior to 2019 that are not “delta-one.” Since the notes have a delta that is less than one, the notes should be exempt from the withholding tax rules specified for dividend equivalents.

The characterization described above is not binding on the U.S. Internal Revenue Service (the “IRS”) or the courts. Thus, it is possible that the IRS would seek to characterize your notes in a manner that results in tax consequences to you that are different from those described above or in the accompanying product supplement. For a more detailed discussion of certain alternative characterizations with respect to your notes and certain other considerations with respect to your investment in the notes, you should consider the discussion set forth in “U.S. Federal Income Tax Summary” of the product supplement. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the notes for U.S. federal income tax or other tax purposes.

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of the notes for U.S. federal income tax purposes. You should also consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the notes 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.

Market-Linked Investments Classification

MLPF&S classifies certain market-linked investments (the “Market-Linked Investments”) into categories, each with different investment characteristics. The following description is meant solely for informational purposes and is not intended to represent any particular Enhanced Income Market-Linked Investment or guarantee any performance.

Enhanced Income Market-Linked Investments are short- to medium-term market-linked notes that offer you a way to enhance your income stream, either through variable or fixed-interest coupons, an added payout at maturity based on the performance of the linked asset, or both. In exchange for receiving current income, you will generally forfeit upside potential on the linked asset. Even so, the prospect of higher interest payments and/or an additional payout may equate to a higher return potential than you may be able to find through other fixed-income securities. Enhanced Income Market-Linked Investments generally do not include market downside protection. The degree to which your principal is repaid at maturity is generally determined by the performance of the linked asset. Although enhanced income streams may help offset potential declines in the asset, you can still lose part or all of your original investment.
