The notes are being issued by Canadian Imperial Bank of Commerce (“CIBC”). There are important differences between the notes and a conventional debt security, including different investment risks and certain additional costs. See “Risk Factors” and “Additional Risk Factors” beginning on page TS-6 of this term sheet and “Risk Factors” beginning on page PS-7 of product supplement EQUITY STR-1.

The initial estimated value of the notes as of the pricing date is expected to be between $8.926 and $9.218 per unit, which is less than the public offering price listed below. See “Summary” on the following page, “Risk Factors” beginning on page TS-6 of this term sheet and “Structuring the Notes” on page TS-14 of this term sheet for additional information. The actual value of your notes at any time will reflect many factors and cannot be predicted with accuracy.

None of the Securities and Exchange Commission (the “SEC”), any state securities commission, or any other regulatory body has approved or disapproved of these securities or determined if this Note Prospectus (as defined below) is truthful or complete.

October    , 2023

Summary

The Autocallable Strategic Accelerated Redemption Securities^® Linked to the MSCI Emerging Markets Index, due October  , 2026 (the “notes”) are our senior unsecured debt securities. The notes are not guaranteed or insured by the Canada Deposit Insurance Corporation, the U.S. Federal Deposit Insurance Corporation or any other governmental agency of the United States, Canada or any other jurisdiction or secured by collateral. The notes are not bail-inable debt securities (as defined on page 6 of the prospectus). The notes will rank equally with all of our other unsecured and unsubordinated debt. Any payments due on the notes, including any repayment of principal, will be subject to the credit risk of CIBC. The notes will be automatically called at the applicable Call Amount if the closing level of the Market Measure, which is the MSCI Emerging Markets Index (the “Index”), on any Observation Date is equal to or greater than the Starting Value. You will not receive any notice from us if the notes are automatically called. If your notes are not called, you will lose all or a portion of the principal amount of your notes. Any payments on the notes will be calculated based on the $10 principal amount per unit and will depend on the performance of the Index, subject to our credit risk. See “Terms of the Notes” below.

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

On the cover page of this term sheet, we have provided the initial estimated value range for the notes. This initial estimated value range was determined based on our pricing models. The initial estimated value as of the pricing date will be based on our internal funding rate on the pricing date, market conditions and other relevant factors existing at that time, and our assumptions about market parameters. For more information about the initial estimated value and the structuring of the notes, see “Structuring the Notes” on page TS-14.

Investor Considerations

We urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Examples of Hypothetical Payments

The following examples are for purposes of illustration only. They are based on hypothetical values and show hypothetical returns on the notes. They illustrate the calculation of the Call Amount or Redemption Amount, as applicable, based on the hypothetical terms set forth below. The actual amount you receive and the resulting return will depend on the actual Starting Value, Threshold Value, Call Level, Observation Levels, Call Premiums, and term of your investment.

The following examples do not take into account any tax consequences from investing in the notes. These examples are based on:

The hypothetical Starting Value of 100.00 used in these examples has been chosen for illustrative purposes only, and does not represent a likely actual Starting Value of the Index.

For recent actual levels of the Index, see “The Index” section below. The Index is a price return index and as such the level of the Index will not include any income generated by dividends paid on the stocks included in the Index, which you would otherwise be entitled to receive if you invested in those stocks directly. In addition, all payments on the notes are subject to issuer credit risk.

Notes Are Called on an Observation Date

The notes will be called at $10.00 plus the applicable Call Premium if the Observation Level on one of the Observation Dates is equal to or greater than the Call Level. After the notes are called, they will no longer remain outstanding and there will not be any further payments on the notes.

Example 1 - The Observation Level on the first Observation Date is 110.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $1.00 = $11.00 per unit.

Example 2 - The Observation Level on the first Observation Date is below the Call Level, but the Observation Level on the second Observation Date is 150.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $2.00 = $12.00 per unit.

Example 3 - The Observation Levels on the first two Observation Dates are below the Call Level, but the Observation Level on the third and final Observation Date is 105.00. Therefore, the notes will be called at $10.00 plus the Call Premium of $3.00 = $13.00 per unit.

Notes Are Not Called on Any Observation Date

Example 4 - The notes are not called on any Observation Date and the Ending Value is less than the Threshold Value. The Redemption Amount will be less, and possibly significantly less, than the principal amount. For example, if the Ending Value is 50.00, the Redemption Amount per unit will be:

Risk Factors

There are important differences between the notes and a conventional debt security. An investment in the notes involves significant risks, including those listed below. You should carefully review the more detailed explanation of risks relating to the notes in the “Risk Factors” sections beginning on page PS-7 of product supplement EQUITY STR-1, page S-1 of the prospectus supplement, and page 1 of the prospectus identified above. We also urge you to consult your investment, legal, tax, accounting, and other advisors before you invest in the notes.

Structure-related Risks

Valuation- and Market-related Risks

Conflict-related Risks

Market Measure-related Risks

Tax-related Risks

Additional Risk Factors

There are risks associated with emerging markets. An investment in the notes will involve risks that are associated with investments that are linked to the equity securities of issuers from emerging markets. Many of the issuers included in the Index are based in nations that are undergoing rapid institutional change, including the restructuring of economic, political, financial and legal systems. The regulatory and tax environments in these nations may be subject to change without review or appeal and many emerging markets suffer from underdevelopment of their capital markets and their tax systems. In addition, in some of these nations, issuers of the relevant securities face the threat of expropriation of their assets and/or nationalization of their businesses. It may be more difficult for an investor in these markets to monitor investments in these companies, because these companies may be subject to fewer disclosure requirements than companies in developed markets, and economic and financial data about some of these countries may be unreliable.

Recent executive orders could adversely affect your investment in the notes. Pursuant to recent executive orders, U.S. persons are prohibited from engaging in transactions in publicly traded securities of certain companies that are determined to be linked to the military, intelligence and security apparatus of the People’s Republic of China. The prohibition also covers any securities that are derivative of, or are designed to provide investment exposure to, such securities. In response to this, the Index sponsor announced that it removed a small number of companies from the Index. If in the future any existing constituent of the Index is designated as such a prohibited company, the value of such constituent may be adversely affected, perhaps significantly, which would adversely affect the performance of the Index. In addition, under these circumstances, the Index sponsor has publicly announced that it intends to remove any such constituent from the Index. Any changes to the composition of the Index in response to the executive orders described above may adversely affect the performance of the Index and the notes.

Other Terms of the Notes

Market Measure Business Day

The following definition shall supersede and replace the definition of a “Market Measure Business Day” set forth in product supplement EQUITY STR -1.

A “Market Measure Business Day” means a day on which:

The Index

All disclosures contained in this term sheet regarding the Index, including, without limitation, its make-up, method of calculation and changes in its components, have been derived from publicly available sources, which we have not independently verified. The information reflects the policies of, and is subject to change by, MSCI Inc. (“MSCI” or the “Index sponsor”). The Index sponsor, which licenses the copyright and all other rights to the Index, has no obligation to continue to publish, and may discontinue publication of, the Index. The consequences of the Index sponsor discontinuing publication of the Index are discussed in the section entitled “Description of the Notes—Discontinuance of an Index” on page PS-27 of product supplement EQUITY STR-1. None of us, the calculation agent, MLPF&S or BofAS accepts any responsibility for the calculation, maintenance or publication of the Index or any successor index.

The Index is a free float-adjusted, capitalization-weighted index that is designed to measure the performance of the large- and mid-cap segments of emerging markets. As of August 31, 2023, the Index consisted of companies from the following developing countries: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Kuwait, Malaysia, Mexico, Peru, Philippines, Poland, Qatar, Saudi Arabia, South Africa, Taiwan, Thailand, Turkey and United Arab Emirates. The Index covers approximately 85% of the free float-adjusted market capitalization in each country. The Index is part of the MSCI Market Cap Weighted Indexes series and is an MSCI Global Investable Market Index. The Index is reported by Bloomberg under the symbol “MXEF.”

The MSCI Indices

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

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

Index Construction

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

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

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

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

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

Defining Market Capitalization Size Segments for Each Market.  Once a market investable equity universe is defined, it is segmented into the following size-based indices, with the following free float-adjusted market capitalization market coverage target ranges:

Index Continuity Rules for the Standard Indices.  In order to achieve index continuity, as well as to provide some basic level of diversification within a market index, and notwithstanding the effect of other index construction rules described in this section, a

minimum number of five constituents will be maintained for a DM Standard Index and a minimum number of three constituents will be maintained for an EM Standard Index.

Classifying Securities under the GICS^®.  All securities in the global investable equity universe are assigned to the industry that best describes their business activities. To this end, MSCI has designed, in conjunction with Standard & Poor’s, the GICS^®. Under the GICS^®, each company is assigned to one sub-industry according to its principal business activity. Therefore, a company can belong to only one industry grouping at each of the four levels of the GICS^®.

Index Maintenance

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

(i)  Semi-Annual Index Reviews (“SAIRs”) in May and November of the Size Segment and Global Value and Growth Indices which include:

(ii)  Quarterly Index Reviews in February and August of the Size Segment Indices aimed at:

(iii)  Ongoing Event-Related Changes: changes of this type are generally implemented in the indices as they occur. Significantly large IPOs are included in the indices after the close of the company’s tenth day of trading.

Index Calculation

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

The following graph shows the daily historical performance of the Index in the period from January 1, 2013 through October 5, 2023. We obtained this historical data from Bloomberg L.P. We have not independently verified the accuracy or completeness of the information obtained from Bloomberg L.P. On October 5, 2023 the closing level of the Index was 930.23.

Historical Performance of the Index

This historical data on the Index is not necessarily indicative of the future performance of the Index or what the value of the notes may be. Any historical upward or downward trend in the level of the Index during any period set forth above is not an indication that the level of the Index is more or less likely to increase or decrease at any time over the term of the notes.

Before investing in the notes, you should consult publicly available sources for the levels of the Index.

License Agreement

CIBC or one of its affiliates has entered into a non-exclusive license agreement with MSCI whereby CIBC and certain of its affiliates, in exchange for a fee, are permitted to use the Index in connection with certain securities, including the notes. We are not affiliated with MSCI, and the only relationship between MSCI and us is any licensing of the use of MSCI’s indices and trademarks relating to them.

NEITHER MSCI, ANY OF ITS AFFILIATES NOR ANY OTHER PARTY INVOLVED IN, OR RELATED TO, THE MAKING OR COMPILING ANY MSCI INDEX HAS ANY OBLIGATION OR LIABILITY TO THE OWNERS OF THE NOTES IN CONNECTION WITH THE ADMINISTRATION, MARKETING OR OFFERING OF THE NOTES.

ALTHOUGH MSCI SHALL OBTAIN INFORMATION FOR INCLUSION IN OR FOR USE IN THE CALCULATION OF THE MSCI INDEXES FROM SOURCES WHICH MSCI CONSIDERS RELIABLE, NEITHER MSCI, ANY OF ITS AFFILIATES NOR ANY OTHER PARTY INVOLVED IN, OR RELATED TO MAKING OR COMPILING ANY MSCI INDEX WARRANTS OR GUARANTEES THE ORIGINALITY, ACCURACY AND/OR THE COMPLETENESS OF ANY MSCI INDEX OR ANY DATA INCLUDED THEREIN.

No purchaser, seller or holder of the notes, or any other person or entity, should use or refer to any MSCI trade name, trademark or service mark to sponsor, endorse, market or promote the notes without first contacting MSCI to determine whether MSCI’s permission is required. Under no circumstances may any person or entity claim any affiliation with MSCI without the prior written permission of MSCI.

Supplement to the Plan of Distribution

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

MLPF&S will in turn purchase the notes from BofAS for resale, and it will receive a selling concession in connection with the sale of the notes in an amount up to the full amount of the underwriting discount set forth on the cover of this term sheet.

We will pay a fee to a broker dealer in which an affiliate of BofAS has an ownership interest for providing certain services with respect to this offering, which will reduce the economic terms of the notes to you.

We may deliver the notes against payment therefor in New York, New York on a date that is greater than two business days following the pricing date. Under Rule 15c6-1 of the Securities Exchange Act of 1934, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, if the initial settlement of the notes occurs more than two business days from the pricing date, purchasers who wish to trade the notes more than two business days prior to the original issue date will be required to specify alternative settlement arrangements to prevent a failed settlement.

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

MLPF&S and BofAS may repurchase and resell the notes, with repurchases and resales being made at prices related to then-prevailing market prices or at negotiated prices, and these prices will include MLPF&S’s and BofAS’s trading commissions and mark-ups or mark-downs. MLPF&S and BofAS may act as principal or agent in these market-making transactions; however, neither is obligated to engage in any such transactions. At their discretion, for a short, undetermined initial period after the issuance of the notes, MLPF&S and BofAS may offer to buy the notes in the secondary market at a price that may exceed the initial estimated value of the notes. Any price offered by MLPF&S or BofAS for the notes will be based on then-prevailing market conditions and other considerations, including the performance of the Index and the remaining term of the notes. However, none of us, MLPF&S, BofAS or any of our respective affiliates is obligated to purchase your notes at any price or at any time, and we cannot assure you that we, MLPF&S, BofAS or any of our respective affiliates will purchase your notes at a price that equals or exceeds the initial estimated value of the notes.

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

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

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

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

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

Structuring the Notes

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

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

BofAS has advised us that the hedging arrangements will include a hedging-related charge of approximately $0.05 per unit, reflecting an estimated profit to be credited to BofAS from these transactions. Since hedging entails risk and may be influenced by unpredictable market forces, additional profits and losses from these hedging arrangements may be realized by BofAS or any third party hedge providers.

Summary of Canadian Federal Income Tax Considerations

In the opinion of Blake, Cassels & Graydon LLP, our Canadian tax counsel, the following summary describes the principal Canadian federal income tax considerations under the Income Tax Act (Canada) and the regulations thereto (the “Canadian Tax Act”) generally applicable at the date hereof to a purchaser who acquires beneficial ownership of a note pursuant to this term sheet and who for the purposes of the Canadian Tax Act and at all relevant times: (a) is neither resident nor deemed to be resident in Canada; (b) deals at arm’s length with CIBC and any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of the note; (c) does not use or hold and is not deemed to use or hold the note in, or in the course of, carrying on a business in Canada; (d) is entitled to receive all payments (including any interest and principal) made on the note; (e) is not a, and deals at arm’s length with any, “specified shareholder” of CIBC for purposes of the thin capitalization rules in the Canadian Tax Act; and (f) is not an entity in respect of which CIBC or any transferee resident (or deemed to be resident) in Canada to whom the purchaser disposes of, loans or otherwise transfers the note is a “specified entity”, and is not a “specified entity” in respect of such a transferee, in each case, for purposes of the Hybrid Mismatch Proposals, as defined below (a “Non-Resident Holder”). Special rules which apply to non-resident insurers carrying on business in Canada and elsewhere are not discussed in this summary.

This summary assumes that no amount paid or payable to a holder described herein will be the deduction component of a “hybrid mismatch arrangement” under which the payment arises within the meaning of proposed paragraph 18.4(3)(b) of the Canadian Tax Act contained in the proposals to amend the Canadian Tax Act released by the Minister of Finance (Canada) on April 29, 2022 with respect to “hybrid mismatch arrangements” (the “Hybrid Mismatch Proposals”). Investors should note that the Hybrid Mismatch Proposals are in consultation form, are highly complex, and there remains significant uncertainty as to their interpretation and application. There can be no assurance that the Hybrid Mismatch Proposals will be enacted in their current form, or at all.

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

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

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

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

Summary of U.S. Federal Income Tax Consequences

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

The U.S. federal income tax considerations of your investment in the notes are uncertain. No statutory, judicial or administrative authority directly discusses how the notes should be treated for U.S. federal income tax purposes. In the opinion of our tax counsel, Mayer Brown LLP, it would generally be reasonable to treat the notes as prepaid cash-settled derivative contracts. Pursuant to the terms of the notes, you agree to treat the notes in this manner for all U.S. federal income tax purposes. If this treatment is respected, you should generally recognize capital gain or loss upon the sale, exchange, redemption or payment on maturity in an amount equal to the difference between the amount you receive at such time and the amount that you paid for your notes. Such gain or loss should generally be long-term capital gain or loss if you have held your notes for more than one year. Non-U.S. holders should consult the section entitled “U.S. Federal Income Tax Summary—Non-U.S. Holders” in product supplement EQUITY STR-1.

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

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of the notes for U.S. federal income tax purposes. You should also consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the notes in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.
