and the applicable series of senior debt securities, including definitions of certain terms used in the indenture and the applicable series of senior debt securities. In this summary, we describe the meaning of only some of the more important terms. You must look to the indenture or the applicable series of senior debt securities for the most complete description of what we describe in summary form in this prospectus.

We may issue the senior debt securities as original issue discount securities, which will be offered and sold at a substantial discount below their stated principal amount. An applicable prospectus supplement relating to the original issue discount securities will describe U.S. federal, Canadian federal and other relevant income tax considerations and other special considerations applicable to them. The senior debt securities may also be issued as indexed securities or securities denominated in foreign currencies or currency units, as described in more detail in an applicable prospectus supplement relating to any of the particular senior debt securities. An applicable prospectus supplement relating to specific senior debt securities will also describe any special considerations and any material U.S. federal and Canadian federal tax considerations applicable to such senior debt securities, including whether and under what circumstances we will pay additional amounts on or for any tax, assessment or governmental charge withheld or deducted and, if so, whether we will have the option to redeem the senior debt securities rather than pay the additional amounts.

When we refer to a series of senior debt securities, we mean a series issued under the indenture pursuant to which the senior debt securities will be issued. Each series of senior debt securities is a single distinct series under the indenture pursuant to which they will be issued and we may issue senior debt securities of each series in such amounts, at such times and on such terms as we wish. The senior debt securities of each series may differ from one another, and from any other series, in their terms, but all senior debt securities of a series together will constitute a single series for all purposes under the indenture pursuant to which they will be issued.

We may issue senior debt securities up to an aggregate principal amount as we may authorize from time to time. The applicable prospectus supplements will describe the terms of any series of senior debt securities being offered, including:

·                                           the title of the series of senior debt securities;

·                                           any limit on the aggregate principal amount of the series of senior debt securities;

·                                           the person to whom interest on a senior debt security is payable, if other than the holder on the regular record date;

·                                           the date or dates on which the series of senior debt securities will mature;

·                                           the rate or rates (which may be fixed or variable) per annum, at which the series of senior debt securities will bear interest, if any, and the date or dates from which that interest, if any, will accrue;

·                                           the dates on which such interest, if any, will be payable and the regular record dates for such interest payment dates;

·                                           the place or places where the principal of, premium, if any, and interest on the senior debt securities is payable;

·                                           any mandatory or optional sinking funds or similar provisions;

·                                           if applicable, the date after which, the price at which, the periods within which and the terms and conditions upon which the senior debt securities may, pursuant to any optional or mandatory redemption provisions, be redeemed and other detailed terms and provisions of those optional or mandatory redemption provisions or provisions for redemption at our option or the option of the holder, if any;

·                                           if applicable, the terms and conditions upon which the senior debt securities may be repayable prior to final maturity at the option of the holder thereof (which option may be conditional);

·                                           the portion of the principal amount of the senior debt securities, if other than the entire principal amount thereof, payable upon acceleration of maturity thereof;

·                                           any other special feature of the series of senior debt securities.

Market-Making Transactions

One or more of our subsidiaries may purchase and resell senior debt securities in market-making transactions after their initial issuance. We may also, subject to applicable law and any required regulatory approvals, purchase senior debt securities in the open market or in private transactions to be held by us or cancelled.

Covenants

Except as otherwise provided in an applicable prospectus supplement with respect to any series of senior debt securities, we are not restricted by the indenture from incurring, assuming or becoming liable for any type of debt or other obligations, from paying dividends or making distributions on our capital stock or purchasing or redeeming our capital stock. The indenture does not require the maintenance of any financial ratios or specified levels of net worth or liquidity, nor does it contain any covenants or other provisions that would limit our or our subsidiaries’ right to incur additional indebtedness, enter into any sale and leaseback transaction or grant liens on our or our subsidiaries’ assets. The indenture does not contain any provisions that would require us to repurchase or redeem or otherwise modify the terms of any of the senior debt securities upon a change in control or other events that may adversely affect the creditworthiness of the senior debt securities, for example, a highly leveraged transaction, except as otherwise specified in this prospectus or any applicable prospectus supplement.

Mergers and Similar Events

The indenture provides that we are permitted to merge, amalgamate, consolidate or otherwise combine with another entity, or to sell or lease substantially all of our assets to another entity, as long as the following conditions are met:

·                                           When we merge, amalgamate, consolidate or otherwise are combined with another entity, or sell or lease substantially all of our assets, the surviving, resulting or acquiring entity is a duly organized entity and is legally responsible for and assumes, either by agreement, operation of law or otherwise, our obligations under such indenture and the senior debt securities issued thereunder.

4

Table of Contents

·                                           The merger, amalgamation, consolidation, other combination, or sale or lease of assets, must not result in an event of default under such indenture. A default for this purpose would include any event that would become an event of default if the requirements for giving us default notice or our default having to exist for a specified period of time were both disregarded.

·                                           We have delivered to the Trustee an officer’s certificate and opinion of counsel stating that the transaction (and any accompanying supplemental indenture) complies with the indenture and all conditions precedent have been complied with.

If the conditions described above are satisfied, we will not need to obtain the consent of the holders of the senior debt securities in order to merge, amalgamate, consolidate or otherwise combine with another entity or to sell or lease substantially all of our assets.

We will not need to satisfy the conditions described above if we enter into other types of transactions, including:

·                                           any transaction in which we acquire the stock or assets of another entity but in which we do not merge, amalgamate, consolidate or otherwise combine;

·                                           any transaction that involves a change of control but in which we do not merge, amalgamate, consolidate or otherwise combine; and

·                                           any transaction in which we sell less than substantially all of our assets.

It is possible that this type of transaction may result in a reduction in our credit rating, may reduce our operating results or may impair our financial condition. Holders of senior debt securities, however, will have no approval right with respect to any transaction of this type.

Modification and Waiver of the Senior Debt Securities

There are three types of changes we can make to the indenture and the senior debt securities issued under that indenture.

Changes Requiring Consent of Each Holder . First, there are changes that cannot be made to the indenture or the senior debt securities without the consent of each holder of a series of senior debt securities affected by the change under the indenture. The following is a list of those types of changes:

·                                           change the stated maturity of the principal or reduce the interest on a senior debt security;

·                                           reduce any amounts due on a senior debt security;

·                                           reduce the amount of principal payable upon acceleration of the maturity of a senior debt security (including the amount payable on an original issue discount security) following a default;

·                                           change the currency of payment on a senior debt security;

·                                           change the place of payment for a senior debt security;

·                                           reduce the percentage of holders of senior debt securities whose consent is needed to modify or amend the indenture;

·                                           reduce the percentage of holders of senior debt securities whose consent is needed to waive compliance with certain provisions of the indenture or to waive certain defaults; or

·                                           modify any other aspect of the provisions dealing with modification and waiver of the indenture.

Changes Requiring a Majority Consent . The second type of change to the indenture and the senior debt securities is the kind that requires the consent of holders of senior debt securities owning not less than a majority of the principal amount of the particular series affected. Most changes fall into this category, except for clarifying changes and certain other changes that would not adversely affect in any material respect holders of the senior debt

securities. We may also obtain a waiver of a past default from the holders of senior debt securities owning a majority of the principal amount of the particular series affected. However, we cannot obtain a waiver of a payment default or any other aspect of the indenture or the senior debt securities described above under “— Changes Requiring Consent of Each Holder” unless we obtain the individual consent of each holder of senior debt securities of the affected series to the waiver.

Changes Not Requiring Consent . The third type of change to the indenture and the senior debt securities does not require the consent by holders of senior debt securities. This type of change is limited to the issuance of new series of senior debt securities under the indenture, clarifications and certain other changes that would not adversely affect in any material respect the interests of the holders of the senior debt securities of any series.

Further Details Concerning Voting . When seeking consent, we will use the following rules to decide the principal amount to attribute to a senior debt security:

·                                           For original issue discount securities, we will use the principal amount that would be due and payable on the voting date if the maturity of the senior debt securities were accelerated to that date because of a default.

·                                           For senior debt securities whose principal amount is not known, we will use a special rule for that senior debt security described in the applicable prospectus supplement.

·                                           For senior debt securities denominated in one or more non-U.S. currencies or currency units, we will use the U.S. dollar equivalent.

Senior debt securities will not be considered outstanding, and therefore not eligible to vote or take other action under the applicable indenture, if we have given a notice of redemption and deposited or set aside in trust for the holders money for the payment or redemption of those senior debt securities. Senior debt securities will also not be considered outstanding, and therefore not eligible to vote or take other action under the applicable indenture, if they have been fully defeased as described below under “— Defeasance — Full Defeasance” or if we or one of our affiliates is the beneficial owner of the senior debt securities.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of outstanding senior debt securities that are entitled to vote or take other action under the applicable indenture. In certain limited circumstances, the trustee will be entitled to set a record date for action by holders. If the trustee or we set a record date for a vote or other action to be taken by holders of a particular series, that vote or action may be taken only by persons who are holders of outstanding senior debt securities of that series on the record date. We or the trustee as applicable, may shorten or lengthen this period from time to time. This period, however, may not extend beyond the 180th day after the record date for the action.

Book-entry and other indirect holders should consult their banks, brokers or other financial institutions for information on how approval may be granted or denied if we seek to change the indenture or the senior debt securities or request a waiver.

Defeasance

The following discussion of full defeasance and covenant defeasance will be applicable to each series of senior debt securities that is denominated in U.S. dollars and has a fixed rate of interest and will apply to other series of senior debt securities if we so specify in the applicable prospectus supplements.

Full Defeasance . If there is a change in U.S. federal income tax law, as described below, we can legally release ourselves from any payment or other obligations on the senior debt securities of a series, called full defeasance, if we put in place the following other arrangements for holders to be repaid:

·                                           We must deposit in trust for the benefit of all holders of the senior debt securities of that series a combination of money and notes or bonds of (i) the U.S. government or (ii) a U.S. government agency or U.S. government-sponsored entity, the obligations of which, in each case, are backed by the full faith and credit of the U.S. government, that will generate enough cash to make interest, principal and any other payments on the senior debt securities of that series on their various due dates sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay and discharge the amounts owned.

6

Table of Contents

·                                           There must be a change in current U.S. federal income tax law or a ruling by the United States Internal Revenue Service that lets us make the above deposit without causing the holders to be taxed on the senior debt securities of that series any differently than if we did not make the deposit and just repaid the senior debt securities of that series ourselves. (Under current U.S. federal income tax law, the deposit and our legal release from the obligations pursuant to the senior debt securities would be treated as though we took back your senior debt securities and gave you your share of the cash and notes or bonds deposited in trust. In that event, you could recognize gain or loss on the senior debt securities you give back to us.)

·                                           We must deliver to the trustee a legal opinion of our counsel confirming the tax law change described above and that the holders of the senior debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would be the case if such deposit, defeasance and discharge had not occurred.

If we ever did accomplish full defeasance, as described above, you would have to rely solely on the trust deposit for repayment on the senior debt securities. You could not look to us for repayment in the event of any shortfall.

Covenant Defeasance . Even without a change in current U.S. federal income tax law, we can make the same type of deposit as described above, and we will be released from the restrictive covenants under the senior debt securities of a series that may be described in the applicable prospectus supplements. This is called covenant defeasance. In that event, you would lose the protection of these covenants but would gain the protection of having money and U.S. government, U.S. government agency or U.S. government-sponsored entity notes or bonds set aside in trust to repay the senior debt securities. In order to achieve covenant defeasance, we must do the following:

·                                           Deposit in trust for the benefit of all holders of the senior debt securities of that series a combination of money and notes or bonds of (i) the U.S. government or (ii) a U.S. government agency or U.S. government-sponsored entity, the obligations of which, in each case, are backed by the full faith and credit of the U.S. government, that will generate enough cash to make interest, principal and any other payments on the senior debt securities of that series on their various due dates sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay and discharge the amounts owned.

·                                           Deliver to the trustee a legal opinion of our counsel confirming that the holders of the senior debt securities of that series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit and covenant defeasance and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would be the case if such deposit and covenant defeasance had not occurred.

If we accomplish covenant defeasance, certain provisions of the indenture and the senior debt securities would no longer apply:

·                                           Covenants applicable to the series of senior debt securities and described in the applicable prospectus supplements.

·                                           Any events of default relating to breach of those covenants.

If we accomplish covenant defeasance, you can still look to us for repayment of the senior debt securities if there were a shortfall in the trust deposit. In fact, if one of the remaining events of default occurs (such as a bankruptcy) and the senior debt securities become immediately due and payable, there may be such a shortfall.

Events of Default

You will have special rights if an “event of default” occurs and is not cured, as described later in this subsection.

7

Table of Contents

What is an Event of Default?

Under the indenture, the term “event of default” means in respect of any series of senior debt securities any of the following:

·                                           We do not pay the principal of or any premium on a senior debt security of that series within five days of its due date.

·                                           We do not pay interest on a senior debt security of that series for more than 30 days after its due date.

·                                           We file for bankruptcy or certain other events of bankruptcy, insolvency or reorganization occur.

·                                           Any other event of default described in an applicable prospectus supplement occurs.

Remedies If an Event of Default Occurs . If an event of default occurs, the trustee will have special duties. In that situation, the trustee will be obligated to use those of its rights and powers under the applicable indenture, and to use the same degree of care and skill in doing so, that a prudent person would use in that situation in conducting his or her own affairs. If an event of default has occurred and has not been cured, the trustee or the holders of at least 25% in principal amount of the outstanding senior debt securities of the affected series may declare the entire principal amount of (or, in the case of original issue discount securities, the portion of the principal amount that is specified in the terms of the affected senior debt security) and interest on all of the senior debt securities of that series to be due and immediately payable. This is called a “declaration of acceleration”. The declaration of acceleration is not, however, an automatic right upon the occurrence of an event of default, and for such acceleration to be effective, the trustee must take the aforementioned action or the holders must direct the trustee to act as described in this section below. Furthermore, a declaration of acceleration may be cancelled in certain circumstances, but only before a judgment or decree based on the acceleration has been obtained, by the holders of at least a majority in principal amount of the senior debt securities of the affected series. If any provisions of applicable Canadian banking law prohibit the payment of any amounts due under the senior debt securities before a specified time, then the obligation to make such payment shall be subject to such prohibition.

You should read carefully the applicable prospectus supplements relating to any series of senior debt securities which are original issue discount securities for the particular provisions relating to acceleration of the maturity of a portion of the principal amount of original issue discount securities upon the occurrence of an event of default and its continuation.

Except in cases of default in which the trustee has the special duties described above, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee protection from expenses and liability called an indemnity satisfactory to the trustee. If such an indemnity is provided, the holders of a majority in principal amount of the outstanding senior debt securities of the relevant series may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. These majority holders may also direct the trustee in performing any other action under the applicable indenture with respect to the senior debt securities of that series.

Before you bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the senior debt securities the following must occur:

·                                           the holder of the senior debt security must give the trustee written notice that an event of default has occurred and remains uncured;

·                                           the holders of not less than 25% in principal amount of all outstanding senior debt securities of the relevant series must make a written request that the trustee take action because of such event of default;

·                                           such holder or holders must offer indemnity satisfactory to the trustee against the cost and other liabilities of taking that action;

·                                           the trustee must have not taken action for 90 days after receipt of the above notice and offer of indemnity; and

8

Table of Contents

·                                           the trustee has not received any direction from a majority in principal amount of all outstanding senior debt securities of the relevant series that is inconsistent with such written request during such 90-day period.

However, you are entitled at any time to bring a lawsuit for the payment of money due on your senior debt security on or after its due date.

BOOK-ENTRY AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS, BROKERS OR OTHER FINANCIAL INSTITUTIONS FOR INFORMATION ON HOW TO GIVE NOTICE OR DIRECTION TO OR MAKE A REQUEST OF THE TRUSTEE AND TO MAKE OR CANCEL A DECLARATION OF ACCELERATION.

We will give to the trustee every year a written statement of certain of our officers certifying that to their knowledge we are in compliance with the applicable indenture and the senior debt securities issued under it, or else specifying any default.

Form, Exchange and Transfer

Unless we specify otherwise in an applicable prospectus supplement, the senior debt securities will be issued:

·                                           only in fully-registered form;

·                                           without interest coupons; and

·                                           in denominations of US$2,000 and integral multiples of US$1,000 in excess thereof.

If a senior debt security is issued as a registered global senior debt security, only the depositary will be entitled to transfer and exchange the senior debt security as described in this subsection because the depositary will be the sole registered holder of the senior debt security and is referred to below as the “holder.” Those who own beneficial interests in a global senior debt security do so through participants in the depositary’s securities clearance system, and the rights of these indirect owners will be governed by the applicable procedures of the depositary and its participants. We describe book-entry procedures below under “Legal Ownership and Book-Entry Issuance.”

Holders of senior debt securities issued in fully-registered form may have their senior debt securities broken into more senior debt securities of smaller denominations of not less than US$2,000, or combined into fewer senior debt securities of larger denominations, as long as the total principal amount is not changed. This is called an exchange.

Holders may exchange or register the transfer of senior debt securities at the office of the trustee. Senior debt securities may be transferred by endorsement. Holders may also replace lost, stolen or mutilated senior debt securities at that office. The trustee acts as our agent for registering senior debt securities in the names of holders and registering the transfer of senior debt securities. We may change this appointment to another entity or perform it ourselves. The entity performing the role of maintaining the list of registered holders is called the security registrar. It will also record transfers. The trustee may require an indemnity before replacing any senior debt securities.

Holders will not be required to pay a service charge to register the transfer or exchange of senior debt securities, but holders may be required to pay for any tax or other governmental charge associated with the exchange or transfer. The registration of a transfer or exchange will only be made if the security registrar is satisfied with your proof of ownership.

If we designate additional agents, they will be named in the applicable prospectus supplements. We may cancel the designation of any particular agent. We may also approve a change in the office through which any agent acts.

If the senior debt securities are redeemable and we redeem less than all of the senior debt securities of a particular series, we may block the registration of transfer or exchange of senior debt securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders entitled to receive the mailing. We may also refuse to register transfers or exchanges of senior debt securities selected for redemption, except that we will continue to permit registration of transfers and exchanges of the unredeemed portion of any senior debt security being partially redeemed.

The Trustee

The trustee makes no representation or warranty, whether express or implied, with respect to CIBC or the senior debt securities and other matters described in this prospectus. The trustee has not prepared or reviewed any of the information included in this prospectus, except the trustee has consented to the use of its name. Such approval does not constitute a representation or approval by the trustee of the accuracy or sufficiency of any information contained in this prospectus.

Payment and Paying Agents

We will pay interest to the person listed in the trustee’s records at the close of business on a particular day in advance of each due date for interest, even if that person no longer owns the senior debt security on the interest due date. That particular day, usually about two weeks in advance of the interest due date, is called the regular record date and will be stated in an applicable prospectus supplement. Holders buying and selling senior debt securities must work out between them how to compensate for the fact that we will pay all the interest for an interest period to the one who is the registered holder on the regular record date. The most common manner is to adjust the sale price of the senior debt securities to prorate interest fairly between buyer and seller. This prorated interest amount is called accrued interest.

We will pay interest, principal and any other money due on the senior debt securities at the office of the paying agent or such other office as may be agreed upon. Holders must make arrangements to have their payments picked up at or wired from that office or such other office as may be agreed upon. We may also choose to pay interest by mailing checks.

BOOK-ENTRY AND OTHER INDIRECT HOLDERS SHOULD CONSULT THEIR BANKS, BROKERS OR OTHER FINANCIAL INSTITUTIONS FOR INFORMATION ON HOW THEY WILL RECEIVE PAYMENTS.

We may also arrange for additional payment offices and may cancel or change these offices, including our use of the trustee’s corporate trust offices. These offices are called paying agents. We may also choose to act as our own paying agent or choose one of our subsidiaries to do so. We must notify holders of changes in the paying agents for any particular series of senior debt securities.

Conversion or Exchange of Senior Debt Securities

If and to the extent mentioned in the applicable prospectus supplement, any series of senior debt securities may be optionally or mandatorily convertible or exchangeable for stock or other securities of CIBC or another entity or entities, into the cash value therefor or into any combination of the above. The specific terms on which any senior debt securities series may be so converted or exchanged (as well as any material U.S. and Canadian federal income tax considerations) will be described in the applicable prospectus supplement. These terms may include provisions for conversion or exchange, either mandatory, at the holder’s option or at our option, in which case the amount or number of securities the senior debt securities holders would receive would be calculated at the time and manner described in the applicable prospectus supplement.

Notices

We and the trustee will send notices regarding the senior debt securities only to registered holders, using the address as listed in the trustee’s records. With respect to who is a registered “holder” for this purpose, see “Legal Ownership and Book-Entry Issuance.”

Regardless of who acts as paying agent, all money paid by us to a paying agent that remains unclaimed at the end of two years after the amount is due to holders will be repaid to us. After that two-year period, holders may look to us for payment and not to the trustee or any other paying agent.

Governing Law

The indenture and the senior debt securities will be governed by New York law, except that, pursuant to the indenture, the ranking of the senior debt securities will be governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein.

Table of Contents

Legal Ownership and Book-Entry Issuance

In this section, we describe special considerations that will apply to registered senior debt securities issued in global i.e., book-entry, form. First we describe the difference between registered ownership and indirect ownership of registered senior debt securities. Then we describe special provisions that apply to global senior debt securities.

Who is the Legal Owner of a Registered Security?

Each senior debt security will be represented either by a certificate issued in definitive form to a particular investor or by one or more global senior debt securities representing senior debt securities. We refer to those who have senior debt securities registered in their own names, on the books that we or the trustee maintains for this purpose, as the “registered holders” of those senior debt securities. Subject to limited exceptions, we and the trustee are entitled to treat the registered holder of a senior debt security as the person exclusively entitled to vote, to receive notices, to receive any interest or other payment in respect of the senior debt security and to exercise all the rights and power as an owner of the senior debt security. We refer to those who own beneficial interests in senior debt securities that are not registered in their own names as indirect owners of those senior debt securities. As we discuss below, indirect owners are not registered holders, and investors in senior debt securities issued in book-entry form or in street name will be indirect owners.

Book-Entry Owners . Unless otherwise noted in an applicable prospectus supplement, we will issue each senior debt security in book-entry form only. This means senior debt securities will be represented by one or more global senior debt securities registered in the name of a financial institution that holds them as depositary on behalf of other financial institutions that participate in the depositary’s book-entry system. These participating institutions, in turn, hold beneficial interests in the senior debt securities on behalf of themselves or their customers.

Under the indenture, subject to limited exceptions and applicable law, only the person in whose name a senior debt security is registered is recognized as the holder of that senior debt security. Consequently, for senior debt securities issued in global form, we will recognize only the depositary as the holder of the senior debt securities and we will make all payments on the senior debt securities, including deliveries of any property other than cash, to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the senior debt securities.

As a result, investors will not own senior debt securities directly. Instead, they will own beneficial interests in a global senior debt security, through a bank, broker or other financial institution that participates in the depositary’s book-entry system or holds an interest through a participant. As long as the senior debt securities are issued in global form, investors will be indirect owners, and not registered holders, of the senior debt securities.

Street Name Owners . We may issue senior debt securities initially in non-global form or we may terminate an existing global senior debt security, as described below under “— Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated.” In these cases, investors may choose to hold their senior debt securities in their own names or in street name. Senior debt securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial interest in those senior debt securities through an account he or she maintains at that institution.

For senior debt securities held in street name, we will, subject to limited exceptions and applicable law, recognize only the intermediary banks, brokers and other financial institutions in whose names the senior debt securities are registered as the holders of those senior debt securities, and we will make all payments on those senior debt securities, including deliveries of any property other than cash, to them. These institutions pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold senior debt securities in street name will be indirect owners, not registered holders, of those senior debt securities.

Registered Holders . Subject to limited exceptions, our obligations, as well as the obligations of the trustee under any indenture and the obligations, if any, of any other third parties employed by us, run only to the registered holders of the senior debt securities. We do not have obligations to investors who hold beneficial interests in global senior debt securities, in street name or by any other indirect means. This will be the case whether an investor

11

Table of Contents

chooses to be an indirect owner of a senior debt security or has no choice because we are issuing the senior debt securities only in global form.

For example, once we make a payment or give a notice to the registered holder, we have no further responsibility for that payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect owners but does not do so. Similarly, if we want to obtain the approval of the holders for any purpose — for example, to amend the indenture for a series of senior debt securities or to relieve us of the consequences of a default or of our obligation to comply with a particular provision of an indenture — we would seek the approval only from the registered holders, and not the indirect owners, of the relevant senior debt securities. Whether and how the registered holders contact the indirect owners is up to the registered holders.

When we refer to “you” in this prospectus, we mean all purchasers of the senior debt securities being offered by this prospectus and the applicable prospectus supplements, whether they are the registered holders or only indirect owners of those senior debt securities. When we refer to “your senior debt securities” in this prospectus, we mean the senior debt securities in which you will hold a direct or indirect interest.

Special Considerations for Indirect Owners . If you hold senior debt securities through a bank, broker or other financial institution, either in book-entry form or in street name, you should check with your own institution to find out:

·                                           how it handles securities payments and notices;

·                                           how it would exercise rights under the senior debt securities if there were a default or other event triggering the need for holders to act to protect their interests; and

·                                           if the senior debt securities are in book-entry form, how the depositary’s rules and procedures will affect these matters.

What is a Global Security?

Unless otherwise noted in the applicable prospectus supplement, we will issue each senior debt security in book-entry form only. Each senior debt security issued in book-entry form will be represented by a global senior debt security that we deposit with and register in the name of one or more financial institutions or clearing systems, or their nominees, which we select. A financial institution or clearing system that we select for any senior debt security for this purpose is called the “depositary” for that senior debt security. A senior debt security will usually have only one depositary but it may have more. Each series of senior debt securities will have one or more of the following as the depositaries:

·                                           The Depository Trust Company, New York, New York (“DTC”);

·                                           Euroclear Bank SA/NV (“Euroclear”);

·                                           Clearstream Banking, S.A. (“Clearstream”); or

·                                           any other clearing system or financial institution named in the applicable prospectus supplements.

The depositaries named above may also be participants in one another’s systems. Thus, for example, if DTC is the depositary for a global senior debt security, investors may hold beneficial interests in that senior debt security through Euroclear or Clearstream, as DTC participants. The depositary or depositaries for your senior debt securities will be named in the applicable prospectus supplements; if none is named, the depositary will be DTC.

A global senior debt security may represent one or any other number of individual senior debt securities. Generally, all senior debt securities represented by the same global senior debt security will have the same terms. We may, however, issue a global senior debt security that represents multiple senior debt securities of the same kind, such as senior debt securities that have different terms and are issued at different times. We call this kind of global senior debt security a master global senior debt security. The applicable prospectus supplements will not indicate whether your senior debt securities are represented by a master global senior debt security.

12

Table of Contents

A global senior debt security may not be transferred to or registered in the name of anyone other than the depositary or its nominee, unless special termination situations arise. We describe those situations below under “— Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated.” As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all senior debt securities represented by a global senior debt security, and investors will be permitted to own only indirect interests in a global senior debt security. Indirect interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose senior debt security is represented by a global senior debt security will not be a holder of the senior debt security, but only an indirect owner of an interest in the global senior debt security.

If an applicable prospectus supplement for a particular senior debt security indicates that the senior debt security will be issued in global form only, then the senior debt security will be represented by a global senior debt security at all times unless and until the global senior debt security is terminated. We describe the situations in which this can occur below under “— Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated.” If termination occurs, we may issue the senior debt securities through another book-entry clearing system or decide that the senior debt securities may no longer be held through any book-entry clearing system.

Special Considerations for Global Securities . As an indirect owner, an investor’s rights relating to a global senior debt security will be governed by the account rules of the depositary and those of the investor’s bank, broker, financial institution or other intermediary through which it holds its interest (such as Euroclear or Clearstream, if DTC is the depositary), as well as general laws relating to securities transfers. We do not recognize this type of investor or any intermediary as a holder of senior debt securities and instead deal only with the depositary that holds the global senior debt security.

If senior debt securities are issued only in the form of a global senior debt security, an investor should be aware of the following:

·                                           an investor cannot cause the senior debt securities to be registered in his or her own name, and cannot obtain non-global certificates for his or her interest in the senior debt securities, except in the special situations we describe below;

·                                           an investor will be an indirect holder and must look to his or her own bank, broker or other financial institution for payments on the senior debt securities and protection of his or her legal rights relating to the senior debt securities, as we describe above under “— Who is the Legal Owner of a Registered Security?”;

·                                           an investor may not be able to sell interests in the senior debt securities to some insurance companies and other institutions that are required by law to own their senior debt securities in non-book-entry form;

·                                           an investor may not be able to pledge his or her interest in a global senior debt security in circumstances in which certificates representing the senior debt securities must be delivered to the lender or other beneficiary of the pledge in order for the pledge to be effective;

·                                           the depositary’s policies will govern payments, deliveries, transfers, exchanges, notices and other matters relating to an investor’s interest in a global senior debt security, and those policies may change from time to time. We and the trustee will have no responsibility for any aspect of the depositary’s policies, actions or records of ownership interests in a global senior debt security. We and the trustee also do not supervise the depositary in any way;

·                                           the depositary may require that those who purchase and sell interests in a global senior debt security within its book-entry system use immediately available funds and your bank, broker or other financial institution may require you to do so as well; and

·                                           financial institutions that participate in the depositary’s book-entry system and through which an investor holds its interest in the global senior debt securities, directly or indirectly, may also have their own policies affecting payments, deliveries, transfers, exchanges, notices and other matters relating to the senior debt securities, and those policies may change from time to time. For example, if you hold an interest in a global senior debt security through Euroclear or Clearstream,

13

Table of Contents

when DTC is the depositary, Euroclear or Clearstream, as applicable, may require those who purchase and sell interests in that senior debt security through them to use immediately available funds and comply with other policies and procedures, including deadlines for giving instructions as to transactions that are to be effected on a particular day. There may be more than one financial intermediary in the chain of ownership for an investor. We and the trustee do not monitor and are not responsible for the policies or actions or records of ownership interests of any of those intermediaries.

Holder’s Option to Obtain a Non-Global Security; Special Situations When a Global Security Will Be Terminated . If we issue any series of senior debt securities in book-entry form but we choose to give the beneficial owners of that series the right to obtain non-global senior debt securities, any beneficial owner entitled to obtain non-global senior debt securities may do so by following the applicable procedures of the depositary, any transfer agent or registrar for that series and that owner’s bank, broker or other financial institution through which that owner holds its beneficial interest in the senior debt securities. If you are entitled to request a non-global certificate and wish to do so, you will need to allow sufficient lead time to enable us or our agent to prepare the requested certificate.

In addition, in a few special situations described below, a global senior debt security will be terminated and interests in it will be exchanged for certificates in non-global form representing the senior debt securities it represented. After that exchange, the choice of whether to hold the senior debt securities directly or in street name will be up to the investor. Investors must consult their own banks, brokers or other financial institutions, to find out how to have their interests in a global senior debt security transferred on termination to their own names, so that they will be holders. We have described the rights of holders and street name investors above under “— Who is the Legal Owner of a Registered Security?”.

The special situations for termination of a global senior debt security are as follows:

·                                           the depositary notifies us that it is unwilling, unable or no longer permitted under applicable law to continue as depositary for that global senior debt security and we do not appoint another institution to act as depositary within 60 days;

·                                           we notify the trustee that we wish to terminate that global senior debt security; or

·                                           an event of default has occurred with regard to these senior debt securities and has not been cured or waived.

If a global senior debt security is terminated, only the depositary, and neither we nor the trustee for any senior debt securities, is responsible for deciding the names of the institutions in whose names the senior debt securities represented by the global senior debt security will be registered and, therefore, who will be the registered holders of those senior debt securities.

Considerations Relating to DTC

DTC has informed us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that DTC participants deposit with DTC. DTC also facilitates the settlement among DTC participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in DTC participants’ accounts, thereby eliminating the need for physical movement of certificates. DTC participants include securities brokers and dealers, banks, trust companies and clearing corporations, and may include other organizations. The Depositary Trust & Clearing Corporation (“DTCC”) is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system also is available to others such as banks, brokers, dealers, trust companies and clearing corporations that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The rules applicable to DTC and DTC participants are on file with the SEC.

Purchases of senior debt securities within the DTC system must be made by or through DTC participants, who will receive a credit for the senior debt securities on DTC’s records. Transfers of ownership interests in the

14

Table of Contents

senior debt securities are accomplished by entries made on the books of participants acting on behalf of beneficial owners.

Redemption notices will be sent to DTC’s nominee, Cede & Co., as the registered holder of the senior debt securities. If less than all of the senior debt securities are being redeemed, DTC will determine the amount of the interest of each direct participant to be redeemed in accordance with its then-current procedures.

In instances in which a vote is required, neither DTC nor Cede & Co. will itself consent or vote with respect to the senior debt securities. Under its usual procedures, DTC would mail an omnibus proxy to the relevant trustee as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts such senior debt securities are credited on the record date (identified in a listing attached to the omnibus proxy).

Distribution payments on the senior debt securities will be made by the relevant trustee to DTC. DTC’s usual practice is to credit direct participants’ accounts on the relevant payment date in accordance with their respective holdings shown on DTC’s records unless DTC has reason to believe that it will not receive payments on such payment date. Payments by participants to beneficial owners will be governed by standing instructions and customary practices and will be the responsibility of such participants and not of DTC, the relevant trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of distributions to DTC is the responsibility of the relevant trustee, and disbursements of such payments to the beneficial owners are the responsibility of direct and indirect participants.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be accurate, but we assume no responsibility for the accuracy thereof. We do not have any responsibility for the performance by DTC or its participants of their respective obligations as described herein or under the rules and procedures governing their respective operations.

Considerations Relating to Clearstream and Euroclear

Clearstream and Euroclear are securities clearance systems in Europe. Clearstream and Euroclear have respectively informed us that Clearstream and Euroclear each hold securities for their customers and facilitate the clearance and settlement of securities transactions by electronic book-entry transfer between their respective account holders. Clearstream and Euroclear provide various services including safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream and Euroclear also deal with domestic securities markets in several countries through established depositary and custodial relationships. Clearstream and Euroclear have established an electronic bridge between their two systems across which their respective participants may settle trades with each other. Clearstream and Euroclear customers are world-wide financial institutions including underwriters, securities brokers and dealers, banks, trust companies and clearing corporations. Indirect access to Clearstream and Euroclear is available to other institutions that clear through or maintain a custodial relationship with an account holder of either system.

Euroclear and Clearstream may be depositaries for a global senior debt security. In addition, if DTC is the depositary for a global senior debt security, Euroclear and Clearstream may hold interests in the global senior debt security as participants in DTC.

As long as any global senior debt security is held by Euroclear or Clearstream, as depositary, you may hold an interest in the global senior debt security only through an organization that participates, directly or indirectly, in Euroclear or Clearstream. If Euroclear or Clearstream is the depositary for a global senior debt security and there is no depositary in the United States, you will not be able to hold interests in that global senior debt security through any securities clearance system in the United States.

Payments, deliveries, transfers, exchanges, notices and other matters relating to the senior debt securities made through Euroclear or Clearstream must comply with the rules and procedures of those systems. Those systems could change their rules and procedures at any time. We have no control over those systems or their participants and we take no responsibility for their activities. Transactions between participants in Euroclear or Clearstream, on one hand, and participants in DTC, on the other hand, when DTC is the depositary, would also be subject to DTC’s rules and procedures.

Special Timing Considerations Relating to Transactions in Euroclear and Clearstream . Investors will be able to make and receive through Euroclear and Clearstream payments, deliveries, transfers, exchanges, notices and other transactions involving any senior debt securities held through those systems only on days when those systems

15

Table of Contents

are open for business. Those systems may not be open for business on days when banks, brokers and other financial institutions are open for business in the United States.

In addition, because of time-zone differences, U.S. investors who hold their interests in the senior debt securities through these systems and wish to transfer their interests, or to receive or make a payment or delivery or exercise any other right with respect to their interests, on a particular day may find that the transaction will not be effected until the next business day in Luxembourg or Brussels, as applicable. Thus, investors who wish to exercise rights that expire on a particular day may need to act before the expiration date. In addition, investors who hold their interests through both DTC and Euroclear or Clearstream may need to make special arrangements to finance any purchases or sales of their interests between the U.S. and European clearing systems, and those transactions may settle later than would be the case for transactions within one clearing system.

obligation was outstanding which adjustment is determined by reference to a change in the purchasing power of money.

In the event that a senior debt security is redeemed, cancelled, repurchased or purchased, as the case may be, by CIBC or any other resident or deemed resident of Canada (a “Canadian Transferee”) from a Non-Resident Holder, or is otherwise assigned or transferred by a Non-Resident Holder, to a Canadian Transferee for an amount which exceeds, generally, the issue price thereof, all or a portion of such excess may be deemed to be interest and may be subject to Canadian non-resident withholding tax if: (i) all or a portion of such interest is participating debt interest and (ii) in certain circumstances, the senior debt security is not considered to be an “excluded obligation” for the purposes of the Canadian Tax Act. A senior debt security which is not an indexed debt obligation, that was issued for an amount not less than 97% of the principal amount (as defined for the purposes of the Canadian Tax Act) of the senior debt security, and the yield from which, expressed in terms of an annual rate (determined in accordance with the Canadian Tax Act) on the amount for which the senior debt security was issued does not exceed 4/3 of the interest stipulated to be payable on the senior debt security, expressed in terms of an annual rate on the outstanding principal amount from time to time, will be an excluded obligation for this purpose.

If applicable, the normal rate of Canadian non-resident withholding tax is 25% but such rate may be reduced under the terms of an applicable income tax treaty.

Generally, there are no other Canadian federal income taxes that would be payable by a Non-Resident Holder as a result of holding or disposing of a senior debt security (including for greater certainty, any gain realized by a Non-Resident Holder on a disposition of a senior debt security).

United States Taxation

The following is a summary of the material U.S. federal income tax consequences that could be applicable to the acquisition, ownership and disposition of the senior debt securities by a U.S. Holder (as defined below) thereof. This section is the opinion of Mayer Brown LLP, our U.S. federal income tax counsel.  This description only applies to senior debt securities held as capital assets within the meaning of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) and issued by us (or through one of our non-U.S. branches).

This summary does not address, except as set forth below, aspects of U.S. federal income taxation that may be applicable to U.S. Holders that are subject to special tax rules, such as:

·                   financial institutions;

·                   insurance companies;

·                   real estate investment trusts;

·                   regulated investment companies;

·                   grantor trusts;

·                   tax-exempt organizations;

·                   persons that will own senior debt securities through partnerships or other pass-through entities;

·                   dealers or traders in securities or currencies;

·                   certain former citizens or long-term residents of the United States;

·                   holders that will hold a senior debt security as part of a position in a straddle or as part of a hedging, conversion or integrated transaction for U.S. federal income tax purposes; or

·                   holders that have a functional currency other than the U.S. dollar.

This summary does not address the U.S. federal estate and gift tax, alternative minimum tax, or Medicare unearned income tax consequences of the acquisition, ownership or disposition of the senior debt securities.  This summary only addresses the U.S. federal income tax treatment

18

Table of Contents

of holders that acquire the senior debt securities as part of the initial distribution at their issue price (as defined below).

Each prospective purchaser should consult its tax advisor with respect to the U.S. federal, state, local and non-U.S. tax consequences of acquiring, owning and disposing of the senior debt securities and any consequences arising on account of the purchaser’s particular circumstances.

This summary is based on the Code, existing and proposed U.S. Treasury Regulations, administrative pronouncements and judicial decisions, as well as on the income tax treaty between the United States of America and Canada, each as available and as of the date hereof. All of the foregoing are subject to change, possibly with retroactive effect, or differing interpretations which could affect the tax consequences described herein.

For purposes of this summary, a “U.S. Holder” is a beneficial owner of senior debt securities who for U.S. federal income tax purposes is any of the following:

·                   an individual citizen or resident of the United States;

·                   a corporation (or any other entity that is treated as a corporation for U.S. federal income tax purposes) organized in or under the laws of the United States or any state thereof, including the District of Columbia;

·                   an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

·                   a trust (1) that validly elects to be treated as a U.S. person for U.S. federal income tax purposes or (2)(a) the administration over which a U.S. court can exercise primary supervision and (b) all of the substantial decisions of which one or more U.S. persons have the authority to control.

If a partnership (or any other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the senior debt securities, the tax treatment of the partnership and a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. Such partner or partnership should consult its own tax advisor regarding the U.S. federal income tax consequences of the purchase, ownership and disposition of the senior debt securities.

Payments Designated as Interest

We will report interest paid to a U.S. Holder on a senior debt security as includible in the U.S. Holder’s gross income as ordinary income in accordance with its usual method of tax accounting, regardless of whether the senior debt security is treated as indebtedness for U.S. federal income tax purposes. In addition, interest on the senior debt securities will be treated as foreign source income for U.S. federal income tax purposes. Subject to certain conditions and limitations, non-U.S. taxes, if any, withheld on interest payments may be treated as non-U.S. taxes eligible for credit against a U.S. Holder’s U.S. federal income tax liability. The limitation on non-U.S. taxes eligible for the U.S. foreign tax credit is calculated separately with respect to

19

Table of Contents

specific “baskets” of income. Interest on the senior debt securities generally will constitute “passive category income,” or, in the case of certain U.S. Holders, “general category income.” As an alternative to the tax credit, a U.S. Holder may elect to deduct such taxes (the election would then apply to all non-U.S. income taxes such U.S. Holder paid in that taxable year). The rules governing the U.S. foreign tax credit are complex. U.S. Holders are urged to consult their tax advisor regarding the availability of the U.S. foreign tax credit under their particular circumstances.

Sale, Exchange, Retirement or Other Disposition of Senior Debt Securities Treated as Debt

Upon the sale, exchange, retirement or other disposition of a senior debt security, a U.S. Holder will recognize taxable gain or loss equal to the difference, if any, between the amount realized on the sale, exchange, retirement or other disposition, other than accrued but unpaid interest which will be taxable as interest, and such U.S. Holder’s adjusted tax basis in the senior debt security. A U.S. Holder’s adjusted tax basis in a senior debt security generally will equal the cost of the senior debt security to such U.S. Holder, and any such gain or loss will generally be capital gain or loss. For a non-corporate U.S. Holder, under current law, the maximum marginal U.S. federal income tax rate applicable to the gain will be generally lower than the maximum marginal U.S. federal income tax rate applicable to ordinary income if the U.S. Holder’s holding period for the senior debt securities exceeds one year ( i.e. , such gain is long-term capital gain). Any gain or loss realized on the sale, exchange, retirement or other disposition of a senior debt security generally will be treated as U.S. source gain or loss, as the case may be. Consequently, a U.S. Holder may not be able to claim a credit for any non-U.S. tax imposed upon a disposition of a senior debt security. The deductibility of capital losses is subject to limitations.

Senior Debt Securities Treated as Derivatives

Certain senior debt securities will not be treated as indebtedness for federal income tax purposes, but will be treated as prepaid cash-settled derivative contracts.  In this case, holders 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 they receive at such time and their tax basis in the securities. In general, their tax basis in the securities will be equal to the price you paid for them. Such gain or loss should generally be long-term capital gain or loss if they have held their securities for more than one year. 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 and is generally taxed at ordinary income rates where the property is held for one year or less. The deductibility of capital losses is subject to limitations. The holding period for securities of a U.S. holder who acquires the securities upon issuance will generally begin on the date after the issue date (i.e., the settlement date) of the securities. If the securities are held by the same U.S. holder until maturity, that holder’s holding period will generally include the maturity date.

The U.S. Treasury Department and the Internal Revenue Service released a 2008 notice that may affect the taxation of holders of securities taxed as prepaid derivatives. According to the notice, the Internal Revenue Service and the U.S. Treasury are 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 comments on the subject. The notice also states that the

20

Table of Contents

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 any 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.

Senior Debt Securities Treated as Contingent Payment Debt Instruments

Certain senior debt securities may be treated as a single debt instrument subject to the special tax rules governing contingent payment debt instruments. If the senior debt 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 senior debt 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 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 senior debt 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 senior debt 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 senior debt securities. In general, a U.S. holder’s adjusted basis in such senior debt securities will equal the amount the holder paid for the senior debt securities, increased by the amount of interest that was previously accrued with respect to the senior debt 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.

Other Variations

To the extent we issue floating rate senior debt securities, index linked senior debt securities, original issue discount senior debt securities, equity linked senior debt securities, credit linked senior debt securities, commodity linked senior debt securities, non-U.S. currency senior debt securities, dual currency senior debt securities or any other senior debt securities where the above summary is not applicable or does not contain a summary of all of the material U.S. federal income tax consequences that could be applicable to the acquisition, ownership and disposition of any such senior debt securities by a U.S. Holder, the applicable prospectus supplement, product supplement or pricing supplement will contain additional or modified disclosure concerning the material U.S. federal income tax consequences relevant to such type of senior debt security as appropriate.

Medicare Tax

A U.S. holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, is subject to a 3.8% tax on the lesser of (1) the U.S. holder’s “net investment income” (or “undistributed net investment income” in the case of an estate or trust) for the relevant taxable year and (2) the excess of the U.S. holder’s modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals is between $125,000 and $250,000, depending on the individual’s circumstances). A holder’s net investment income generally includes its interest income and its net gains from the disposition of securities, unless such interest income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). If you are a U.S. holder that is an individual, estate or trust, you are urged to consult your tax advisors regarding the applicability of the Medicare tax to your income and gains in respect of your investment in the debt securities.

U.S. Backup Withholding and Information Reporting

Backup withholding and information reporting requirements apply to certain payments of principal of, and interest on, an obligation and to proceeds of the sale or redemption of an obligation, to certain non-corporate holders of senior debt securities that are U.S. persons. Information reporting generally will apply to payments of principal of, and interest on, senior debt securities, and to proceeds from the sale or redemption of, senior debt securities within the United States, or by a U.S. payor or U.S. middleman, to a holder of senior debt securities that is a U.S. person (other than an exempt recipient, including a corporation, and certain other persons). The payor will be required to backup withhold on payments made within the United States, or by a U.S. payor or U.S. middleman, on a senior debt security to a holder of a senior debt security that is a U.S. person, other than an exempt recipient, such as a corporation, if the holder fails to furnish its correct taxpayer identification number or otherwise fails to comply with, or establish an exemption from, the backup withholding requirements.

Backup withholding is not an additional tax. You generally will be entitled to credit any amounts withheld under the backup withholding rules against your U.S. federal income tax liability provided the required information is furnished to the United States Internal Revenue Service (“IRS”) in a timely manner.

Additionally, U.S. Holders that are individuals (and, to the extent provided in future regulations, certain entities) may be required to disclose information about their senior debt securities on Form 8938—Statement of Specified Foreign Financial Assets—if the aggregate value of their senior debt securities and their “specified financial assets” exceeds $50,000 (or other thresholds depending on the individual’s exact circumstances). Significant penalties can apply if a U.S. Holder fails to disclose its specified foreign financial assets. U.S. Holders should consult their own tax advisors regarding the possible implications of this legislation in their particular circumstances.

FATCA Withholding

The Foreign Account Tax Compliance provisions of the Code (“FATCA”) assist the IRS in enforcing U.S. taxpayer compliance. FATCA may impose a 30% withholding tax on payments of U.S. source income and on payments of gross proceeds from the sale, exchange or redemption of property that gives rise to U.S. source dividends or interest (as of 1 January 2019), in each case to (i) certain non-U.S. financial institutions that do not enter into and comply with an agreement to provide the IRS information about their accountholders (as defined for purposes of FATCA), comply with certain rules or law implementing an intergovernmental agreement between the United States and the non-U.S. financial institution’s jurisdiction implementing FATCA with respect to such jurisdiction or otherwise qualify for an exemption from, or are deemed to comply with, FATCA (an institution meeting such requirements, a “Compliant FFI”) and (ii) certain other non-U.S. entities that do not provide payors information about their substantial U.S. holders or establish that they have no substantial U.S. holders.

Starting on the later of 1 January 2019 or the date of publication of final U.S. Treasury regulations defining the term “foreign passthru payments” (the “Publication Date”), FATCA may also impose withholding tax on such “foreign passthru payments” relating to obligations issued (or deemed re-issued) after the date that is six months after the Publication Date. Thus, the Issuer may in certain circumstances be required under FATCA to withhold U.S. tax at a rate of 30% on all or a portion of payments of principal and interest which are treated as “foreign passthru payments” made to (i) non-U.S. financial institutions (whether holding the senior debt securities as a beneficial owner or intermediary) unless the payee is a Compliant FFI or (ii) any holders that do not provide information sufficient to determine whether the payee is a U.S. person (“Recalcitrant Holders”). Whether or not FATCA withholding tax could apply to “foreign passthru payments” on the senior debt securities may depend upon an applicable intergovernmental agreement (“IGA”) relating to FATCA between the United States and the jurisdiction of the Issuer, Guarantor or the applicable Issuer Branch of Account.

Specifically, the United States and a number of other jurisdictions have entered into IGAs to facilitate the implementation of FATCA. Pursuant to FATCA and the “Model 1” IGA, an FFI in an IGA signatory country could be treated as a Reporting Financial Institution (“Reporting FI”) not subject to withholding under FATCA on any payments it receives. Further, an FFI in a Model 1 IGA jurisdiction would not be required to withhold under FATCA or an IGA (or any law implementing an IGA) from payments it makes unless it has agreed to do so under the U.S. “qualified intermediary,” “withholding foreign partnership,” or “withholding foreign trust” regimes. Under the Model 1 IGA, a Reporting FI would still be required to report certain information in respect of its account holders and investors to its home government or to the IRS. The United States and Canada have entered into an agreement (the “US-Canada IGA”) based largely on the Model 1 IGA.

We are a Reporting FI pursuant to the US-Canada IGA. However, the FATCA rules, and in particular the rules governing foreign passthru payments, have not yet been fully developed, so the future application of FATCA to the Issuer and the holders of senior debt securities is uncertain. Senior debt securityholders may be required to provide certain information to us or other payors in order (i) for holders to avoid FATCA withholding from payments on the senior debt securities, (ii) for us to avoid the imposition of a FATCA withholding tax on payments to it or (iii) for the Issuer to comply with the rules under FATCA (including laws implementing an IGA thereunder). If a holder (including an intermediary) fails to provide us, or any paying agent

23

Table of Contents

with any correct, complete and accurate information that may be required for the Issuer to comply with FATCA and/or to prevent the imposition of FATCA withholding tax, the Issuer may withhold amounts otherwise distributable to the holder.

The requirements of the US-Canada IGA have been implemented through amendments to the Canadian Income Tax Act and the enactment of the Canada-United States Enhanced Tax Information Exchange Agreement Implementation Act (the “US-Canada IGA Implementation Act”). Under the provisions of the US-Canada IGA Implementation Act, we are required to determine whether financial accounts are held by U.S. persons and must report information on certain accounts owned or controlled by U.S. taxpayers, directly to the Canada Revenue Agency (the “CRA”). We may be required to collect information from holders of senior debt securities (other than senior debt securities that are regularly traded on an established securities market for purposes of the IGA), including such holders’ status as a “Specified U.S. Persons” (as defined in the IGA) and report information regarding such holders’ investment in the senior debt securities to the CRA.

No additional amounts will be paid in respect of any U.S. tax withheld under the FATCA rules from payments on the senior debt securities. Potential investors should consult their tax advisers regarding the implications of the FATCA rules for their investment in senior debt securities, including the implications resulting from the status under these rules of each financial intermediary through which they hold senior debt securities.

While the senior debt securities are in global form and held within a clearing system, it is expected that FATCA will not affect the amount of any payments made under, or in respect of, the senior debt securities by us, any paying agent or the depositary, given that each of the entities in the payment chain beginning with the Issuer and ending with the relevant clearing system is a major financial institution whose business is dependent on compliance with FATCA and that any alternative approach introduced under an intergovernmental agreement will be unlikely to affect the securities. However, FATCA may affect payments made to custodians or intermediaries in the subsequent payment chain leading to the ultimate investor if any such custodian or intermediary generally is unable to receive payments free of FATCA withholding. It also may affect payment to any ultimate investor that is a financial institution that is not entitled to receive payments free of withholding under FATCA, or an ultimate investor that fails to provide its broker (or other custodian or intermediary from which it receives payment) with any information, forms, other documentation or consents that may be necessary for the payments to be made free of FATCA withholding.

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

24

Table of Contents

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.

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”). 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 2017 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.  Regulations under Section 871(m) exempt financial instruments issued in 2017 that are not “delta-one.”

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. For example, if you enter into other transactions relating to U.S. underlying securities, you could be subject to withholding tax or income tax liability under Section 871(m) even if the securities are not Specified Securities

25

subject to Section 871(m) as a general matter. You should consult your tax adviser regarding the potential application of Section 871(m) to the securities.

This prospectus may be delivered by underwriters and dealers in connection with short sales undertaken to hedge exposures under commitments to acquire our securities to be issued on a delayed or contingent basis.

Underwriters, dealers and agents that participate in the distribution of the securities may be underwriters as defined in the Securities Act. Any discounts or commissions that we pay them and any profit they receive when they resell the securities may be treated as underwriting discounts and commissions under that Act. We may have agreements with underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act, to contribute with respect to payments which they may be required to make in respect of such liabilities and to reimburse them for certain expenses.

Underwriters, dealers and agents, and their affiliates or associates, may engage in transactions with us or perform services for us in the ordinary course of business and receive compensation from us.

Each series of offered securities will be a new issue of securities and will have no established trading market. Securities may or may not be listed on a national or foreign securities exchange or automated quotation system. Any underwriters or agents to whom securities are sold for public offering or sale may make, but are not required to make, a market in the securities, and the underwriters or agents may discontinue making a market in the securities at any time without notice. No assurance can be given as to the liquidity or the existence of trading markets for any securities.

Any underwriters utilized may engage in stabilizing transactions and syndicate covering transactions in accordance with Rule 104 of Regulation M under the Exchange Act. Stabilizing transactions permit bids to purchase the offered securities or any underlying security so long as the stabilizing bids do not exceed a specified maximum. Syndicate covering transactions involve purchases of securities in the open market after the distribution has been completed in order to cover syndicate short positions. Such stabilizing transactions and syndicate covering transactions may cause the price of the offered securities to be higher than would be the case in the absence of such transactions.

Selling Restrictions Outside the United States

Except as described in an applicable prospectus supplement, we have taken no action that would permit a public offering of the securities or possession or distribution of this prospectus or any other offering material in any jurisdiction outside the United States where action for that purpose is required. Accordingly, each underwriter will be required to comply with all applicable laws and regulations in force in any jurisdiction in which it purchases, offers or sells securities or possesses or distributes this prospectus or any other offering material and will obtain any consent, approval or permission required by it for the purchase, offer or sale by it of securities under the laws and regulations in force in any jurisdiction to which it is subject or in which it makes such purchases, offers or sales and we shall have no responsibility in relation to this.

With regard to each security, the relevant purchaser will be required to comply with those restrictions that we and the relevant purchaser shall agree and as shall be set out in an applicable supplement.

Market-Making Resales By Affiliates

This prospectus may be used by CIBC World Markets Corp. in connection with offers and sales of the securities in market-making transactions. In a market-making transaction, CIBC World Markets Corp. may resell a security it acquires from other holders, after the original offering and sale of the security. Resales of this kind may occur in the open market or may be privately negotiated, at prevailing market prices at the time of resale or at related or negotiated prices. In these transactions, CIBC World Markets Corp. may act as principal or agent, including as agent for the counterparty in a transaction in which CIBC World Markets Corp. acts as principal, or as agent for both counterparties in a transaction in which CIBC World Markets Corp. does not act as principal. CIBC World Markets Corp. may receive compensation in the form of discounts and commissions, including from both counterparties in some cases.

The securities to be sold in market-making transactions include securities to be issued after the date of this prospectus, as well as securities previously issued.

We do not expect to receive any proceeds from market-making transactions. We do not expect that CIBC World Markets Corp. or any other affiliate that engages in these transactions will pay any proceeds from its market-making resales to us.

In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code provide statutory exemptive relief for certain arm’s-length transactions with a person that is a party in interest or disqualified person solely by reason of providing services to a benefit plan investor or being an affiliate of such a service provider.  Under these provisions, the purchase and sale of the senior debt securities will not constitute a prohibited transaction under ERISA or Section 4975 of the Code, provided that neither the issuer of the senior debt securities nor any of its affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any benefit plan investor involved in the transaction, and provided further that the benefit plan investor pays no more and receives no less than “adequate consideration” in connection with the transaction.  Even if the conditions specified in one or more of these exemptions are met, the scope of the relief provided by these exemptions might or might not cover all acts which might be construed as prohibited transactions.  There can be no assurance that any of these, or any other exemption, will be available with respect to any particular transaction involving the senior debt securities, and prospective acquirers that are benefit plan investors should consult with their legal advisors regarding the applicability of any such exemption.

By acquiring a senior debt security (or interest therein), each purchaser and transferee (and if the purchaser or transferee is a plan, its fiduciary) is deemed to represent, warrant and covenant that either (i) it is not acquiring the senior debt securities (or interest therein) with the assets of a plan; or (ii) the acquisition and holding of the senior debt securities (or interest therein) will not give rise to a nonexempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code because such purchaser or transferee relied on an available prohibited transaction exemption, all of the conditions of which are satisfied, or a violation of similar law.

The foregoing discussion is general in nature and is not intended to be all inclusive.  Due to the complexity of these rules and the penalties that may be imposed upon persons involved in nonexempt prohibited transactions, it is particularly important that fiduciaries, or other persons considering purchasing the senior debt securities on behalf of, or with the assets of, any plan, consult with their counsel regarding the potential applicability of ERISA, Section 4975 of the Code and any similar law to such investment and whether an exemption would be applicable to the purchase and holding of the senior debt securities.

Each purchaser and holder of the senior debt securities has exclusive responsibility for ensuring that its purchase and holding of the senior debt securities does not violate the fiduciary or prohibited transaction rules of ERISA, the Code or any similar laws.  The sale of any senior debt securities to any plan is in no respect a representation by us or any of our affiliates or representatives that such an investment meets all relevant legal requirements with respect to investments by plans generally or any particular plan, or that such an investment is appropriate for plans generally or any particular plan.

LIMITATIONS ON ENFORCEMENT OF U.S. LAWS AGAINST CIBC, ITS MANAGEMENT AND OTHERS

CIBC is a Canadian chartered bank. Many of its directors and executive officers, including many of the persons who signed the registration statement on Form F-3, of which this prospectus is a part, and some of the experts named in this document, are resident outside of the United States, and a substantial portion of CIBC’s assets and all or a substantial portion of the assets of such persons are located outside of the United States. As a result, it may be difficult for United States investors to effect service of process within the United States upon such persons to enforce against them judgments of the courts of the United States predicated upon, among other things, the civil liability provisions of the federal securities laws of the United States. In addition, it may be difficult for United States investors to enforce, in original actions brought in courts in jurisdictions located outside of the United States, among other things, civil liabilities predicated upon such securities laws.

Table of Contents

CIBC has been advised by Blake, Cassels & Graydon LLP, its Canadian counsel, that a judgment of a United States court may be enforceable in Canada if: (a) there is a real and substantial connection between the events, persons and circumstances and the forum in which the United States proceedings occur such that the United States court properly assumed jurisdiction; (b) the United States judgment is final and conclusive and for a sum certain; (c) the defendant was properly served with originating process from the United States court; and (d) the United States law that led to the judgment is not contrary to Canadian public policy, as that term would be applied by a Canadian court. CIBC has been advised that in normal circumstances, only civil judgments and not other rights arising from United States securities legislation (for example, penal or similar awards made by a court in a regulatory prosecution or proceeding) are enforceable in Canada. The enforceability of a United States judgment in Canada will be subject to the requirements that: (i) an action to enforce the United States judgment must be commenced in the Canadian court within any applicable limitation period; (ii) the Canadian court has discretion to stay or decline to hear an action on the United States judgment if the United States judgment is under appeal or there is another subsisting judgment in any jurisdiction relating to the same cause of action; (iii) the Canadian court will render judgment only in Canadian dollars; and (iv) an action in the Canadian court on the United States judgment may be affected by bankruptcy, insolvency or other laws of general application limiting the enforcement of creditors’ rights generally. The enforceability of a United States judgment in Canada will be subject to the following defenses: (i) the United States judgment was obtained by fraud or in a manner contrary to the principles of natural justice; (ii) the United States judgment is for a claim which under the law of the applicable Canadian province would be characterized as based on a foreign revenue, expropriatory, penal or other public law; (iii) the United States judgment is contrary to the public policy of the applicable Canadian province or to an order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act (Canada) or by the Competition Tribunal under the Competition Act (Canada) in respect of certain judgments referred to in these statutes; and (iv)  the United States judgment has been satisfied or is void or voidable under United States law.

(6) That, for the purpose of determining liability of the Registrant under the Securities Act to any purchaser in the initial distribution of the securities, in a primary offering of securities of the Registrant pursuant to this Registration Statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)              Any preliminary prospectus or prospectus of the Registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)           Any free writing prospectus relating to the offering prepared by or on behalf of the Registrant or used or referred to by the Registrant;

(iii)        The portion of any other free writing prospectus relating to the offering containing material information about the Registrant or its securities provided by or on behalf of the Registrant; and

(iv)       Any other communication that is an offer in the offering made by the Registrant to the purchaser.

(7) That, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(8) The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of section 310 of the Trust Indenture Act of 1939, as amended (“Act”) in accordance with the rules and regulations prescribed by the Commission under section 305(b)(2) of the Act.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions set forth in Item 8 above, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
