PART I
Item 1. Business.
GENERAL
Comerica Incorporated (“Comerica”) is a financial services company, incorporated under the laws of the State of Delaware, and headquartered in Detroit, Michigan. As of December 31, 2006, it was among the 20 largest commercial banking companies in the United States. Comerica was formed in 1973 to acquire the outstanding common stock of Comerica Bank (formerly Comerica Bank-Detroit), one of Michigan’s oldest banks (“Comerica Bank”). As of December 31, 2006, Comerica owned directly or indirectly all the outstanding common stock of 2 active banking and 63 non-banking subsidiaries. At December 31, 2006, Comerica had total assets of approximately $58.0 billion, total deposits of approximately $44.9 billion, total loans (net of unearned income) of approximately $47.4 billion and common shareholders’ equity of approximately $5.2 billion.
During 2006 Comerica sold its stake in Munder Capital Management (“Munder”). Munder provides investment advisory services to institutions, municipalities, unions, charitable organizations and private investors, and also serves as investment advisor for Munder Funds.
BUSINESS STRATEGY
Comerica has strategically aligned its operations into 3 major business segments: the Business Bank, the Retail Bank, and Wealth & Institutional Management. In addition to the three major business segments, the Finance Division is also reported as a segment.
The Business Bank is primarily comprised of the following businesses: middle market, commercial real estate, national dealer services, global finance, large corporate, leasing, financial services, and technology and life sciences. This business segment meets the needs of medium-size businesses, multinational corporations and governmental entities by offering various products and services, including commercial loans and lines of credit, deposits, cash management, capital market products, international trade finance, letters of credit, foreign exchange management services and loan syndication services.
The Retail Bank includes small business banking (entities with annual sales under $10 million) and personal financial services, consisting of consumer lending, consumer deposit gathering and mortgage loan origination. In addition to a full range of financial services provided to small business customers, this business segment offers a variety of consumer products, including deposit accounts, installment loans, credit cards, student loans, home equity lines of credit, and residential mortgage loans.
Wealth & Institutional Management offers products and services consisting of personal trust, which is designed to meet the personal financial needs of affluent individuals (as defined by individual net income or wealth), private banking, institutional trust, retirement services, investment management and advisory services, investment banking, and discount securities brokerage services. This business segment also offers the sale of annuity products, as well as life, disability and long-term care insurance products.
The Finance segment includes Comerica’s securities portfolio and asset and liability management activities. This segment is responsible for managing Comerica’s funding, liquidity and capital needs, performing interest sensitivity analysis and executing various strategies to manage Comerica’s exposure to liquidity, interest rate risk, and foreign exchange risk.
In addition, Comerica has positioned itself to deliver financial services in its four primary geographic markets: Midwest & Other Markets, Western, Texas, and Florida. Midwest & Other Markets includes all markets in which Comerica has operations, except for the Western, Texas and Florida markets. Substantially all of Comerica’s international operations are included in the Midwest & Other Markets segment. Currently, Michigan operations represent the significant majority of the Midwest & Other Markets geographic market.
The Western market consists of the states of California, Arizona, Nevada, Colorado and Washington. Currently, California operations represent the significant majority of the Western market.

COMPETITION
The financial services business is highly competitive. Comerica’s banking subsidiaries compete primarily with banks based in its primary areas of operations in the United States for loans, deposits and trust accounts. Through its offices in Arizona, California, Colorado, Delaware, Florida, Illinois, Massachusetts, Michigan, Minnesota, North Carolina, Nevada, New Jersey, New York, Ohio, Tennessee, Texas, Virginia and Washington, Comerica competes with other financial institutions for various deposits, loans and other products and services.
Based on the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 (the “Interstate Act”) and the Gramm-Leach-Bliley Act as described below, Comerica believes that the level of competition in all geographic markets will increase in the future. In addition to banks, Comerica’s banking subsidiaries also face competition from other financial intermediaries, including savings and loan associations, consumer finance companies, leasing companies, venture capital funds, credit unions, investment banks, insurance companies and securities firms.
SUPERVISION AND REGULATION
Banks, bank holding companies and financial institutions are highly regulated at both the state and federal level. Comerica is subject to supervision and regulation at the federal level by the Board of Governors of the Federal Reserve System (“FRB”) under the Bank Holding Company Act of 1956, as amended.
The Gramm-Leach-Bliley Act expanded the activities in which a bank holding company registered as a financial holding company can engage. The conditions to be a financial holding company include, among others, the requirement that each depository institution subsidiary of the holding company be well capitalized and well managed.
Comerica became a financial holding company in 2000. As a financial holding company, Comerica may affiliate with securities firms and insurance companies and engage in activities that are financial in nature. Activities that are “financial in nature” include, but are not limited to: securities underwriting; securities dealing and market making; sponsoring mutual funds and investment companies; insurance underwriting and agency; merchant banking; travel agent services; and activities that the FRB has determined to be financial in nature or incidental or complementary to a financial activity, provided that it does not pose a substantial risk to the safety or soundness of the depository institution or the financial system generally. A bank holding company that is not also a financial holding company is limited to engaging in banking and other activities previously determined by the FRB to be closely related to banking.

Table of Contents

Comerica Bank is chartered by the State of Michigan and at this level is primarily supervised and regulated by the Division of Financial Institutions, Office of Financial and Insurance Services of the Michigan Department of Labor and Economic Growth. Comerica Bank & Trust, National Association is chartered under federal law and subject to supervision and regulation by the Office of the Comptroller of the Currency (“OCC”). Comerica Bank and Comerica Bank & Trust, National Association, are members of the Federal Reserve System (“FRS”). The deposits of both the foregoing banks are insured by the Deposit Insurance Fund of the Federal Deposit Insurance Corporation (“FDIC”) to the extent provided by law.
The FRB supervises non-banking activities conducted by companies directly and indirectly owned by Comerica Incorporated. In addition, Comerica’s non-banking subsidiaries are subject to supervision and regulation by various state, federal and self-regulatory agencies, including, but not limited to, the National Association of Securities Dealers, Inc. (in the case of Comerica Securities, Inc. and Comerica Capital Markets Corporation), the Department of Insurance of the State of Michigan (in the case of Comerica Insurance Services, Inc.), and the Securities and Exchange Commission (in the case of Comerica Securities, Inc. and Comerica Capital Markets Corporation).
In most cases, no FRB approval is required for Comerica to acquire a company engaged in activities that are financial in nature or incidental to activities that are financial in nature, as determined by the FRB. Prior FRB approval, however, is required before Comerica may acquire the beneficial ownership or control of more than 5% of the voting shares or substantially all of the assets of a financial or bank holding company or a bank. Comerica’s current rating under the Community Reinvestment Act of 1977 (“CRA”) is “outstanding”. If any subsidiary bank of Comerica were to receive a rating under the CRA of less than “satisfactory”, Comerica would be prohibited from engaging in certain activities. In addition, Comerica is “well capitalized” and “well managed” under FRB standards. If any subsidiary bank of Comerica were to cease being “well capitalized” or “well managed” under applicable regulatory standards, the FRB could place limitations on Comerica’s ability to conduct the broader financial activities permissible for financial holding companies or impose limitations or conditions on the conduct or activities of Comerica or its affiliates. If the deficiencies persisted, the FRB could order Comerica to divest any subsidiary bank or to cease engaging in any activities permissible for financial holding companies that are not permissible for bank holding companies, or Comerica could elect to conform its non-banking activities to those permissible for a bank holding company that is not also a financial holding company.
Various governmental requirements, including Sections 23A and 23B of the Federal Reserve Act and Regulation W of the FRB, limit borrowings by Comerica and its nonbank subsidiaries from its affiliate insured depository institutions, and also limit various other transactions between Comerica and its nonbank subsidiaries, on the one hand, and its affiliate insured depository institutions, on the other. For example, Section 23A of the Federal Reserve Act limits the aggregate outstanding amount of any insured depository institution’s loans and other “covered transactions” with any particular nonbank affiliate to no more than 10% of the institution’s total capital and limits the aggregate outstanding amount of any insured depository institution’s covered transactions with all of its nonbank affiliates to no more than 20% of its total capital. Section 23A of the Federal Reserve Act also generally requires that an insured depository institution’s loans to its nonbank affiliates be, at a minimum, 100% secured, and Section 23B of the Federal Reserve Act generally requires that an insured depository institution’s transactions with its nonbank affiliates be on arms-length terms.
Set forth below are summaries of selected laws and regulations applicable to Comerica and its domestic banks and other subsidiaries. The summaries are not complete, are qualified in their entirety by references to the particular statutes and regulations, and are not intended as legal advice. A change in applicable law or regulation could have a material effect on the business of Comerica.
Interstate Banking and Branching
Pursuant to the Interstate Banking and Branching Efficiency Act (the “Interstate Act”), a bank holding company may acquire banks in states other than its home state, without regard to the permissibility of such acquisition under state law, but subject to any state requirement that the bank has been organized and operating for a minimum period of time, not to exceed five years, and the requirement that the bank holding company, prior to and following the proposed acquisition, control no more than 10% of the total amount of deposits of insured depository institutions in the United States and no more than 30% of such deposits in that state (or such amount as established by state law if such amount is lower than 30%).

Table of Contents

The Interstate Act also authorizes banks to acquire branch offices outside their home states by merging with out-of-state banks, purchasing branches in other states and establishing de novo branches in other states, thereby creating interstate branching, provided that, in the case of purchasing branches and establishing new branches in a state in which it does not already have banking operations, such state must have “opted-in” to the Interstate Act by enacting a law permitting such branch purchases or de novo branching and, in the case of mergers, such state must not have “opted-out” of that portion of the Interstate Act.
As permitted by the Interstate Act, Comerica has consolidated most of its banking business into one bank, Comerica Bank, with branches in Michigan, California, Texas, Florida, and Arizona.
Dividends
Comerica is a legal entity separate and distinct from its banking and other subsidiaries. Most of Comerica’s revenues result from dividends its bank subsidiaries pay it. There are statutory and regulatory requirements applicable to the payment of dividends by subsidiary banks to Comerica, as well as by Comerica to its shareholders. Certain, but not all, of these requirements are discussed below.
Comerica Bank and Comerica Bank & Trust, National Association are required by federal law to obtain the prior approval of the FRB or the OCC, as the case may be, for the declaration and payment of dividends, if the total of all dividends declared by the board of directors of such bank in any calendar year will exceed the total of (i) such bank’s retained net income (as defined and interpreted by regulation) for that year plus (ii) the retained net income (as defined and interpreted by regulation) for the preceding two years, less any required transfers to surplus or to fund the retirement of preferred stock. Further, federal regulatory agencies can prohibit a banking institution or bank holding company from engaging in unsafe and unsound banking practices and could prohibit the payment of dividends under circumstances in which such payment could be deemed an unsafe and unsound banking practice. In addition, Comerica Bank is also subject to limitations under state law regarding the amount of earnings that may be paid out as dividends, and requiring prior approval for payments of dividends that exceed certain levels.
At January 1, 2007, Comerica’s subsidiary banks, without obtaining prior governmental approvals, could declare aggregate dividends of approximately $261 million from retained net profits of the preceding two years, plus an amount approximately equal to the retained net profits (as measured under current regulations), if any, earned for the period from January 1, 2007 through the date of declaration. Comerica’s subsidiary banks declared dividends of $746 million in 2006, $793 million in 2005 and $691 million in 2004 without the need for prior governmental approvals.
Source of Strength
FRB regulations require that bank holding companies serve as a source of strength to each subsidiary bank and commit resources to support each subsidiary bank. This support may be required at times when a bank holding company may not be able to provide such support without adversely affecting its ability to meet other obligations. Similarly, under the cross-guarantee provisions of the Federal Deposit Insurance Act, in the event of a loss suffered or anticipated by the FDIC (either as a result of the failure of a banking or thrift subsidiary or related to FDIC assistance provided to such a subsidiary in danger of failure), the other banking subsidiaries may be assessed for the FDIC’s loss, subject to certain exceptions.
FDICIA
The Federal Deposit Insurance Corporation Improvement Act (“FDICIA”) requires, among other things, the federal banking agencies to take “prompt corrective action” in respect of depository institutions that do not meet minimum capital requirements. FDICIA establishes five capital tiers: “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” and “critically undercapitalized.” A depository institution’s capital tier will depend upon where its capital levels are in relation to various relevant capital measures, which, among others, include a Tier 1 and total risk-based capital measure and a leverage ratio capital measure.
Regulations establishing the specific capital tiers provide that, for a depository institution to be well capitalized, it must have a total risk-based capital ratio of at least 10% and a Tier 1 risk-based capital ratio of at least 6%, a Tier 1 leverage ratio of at least 5% and not be subject to any specific capital order or directive. For an institution to be adequately capitalized, it must have a total risk-based capital ratio of at least 8%, a Tier 1 risk-based capital ratio of

5


Table of Contents

at least 4%, and a Tier 1 leverage ratio of at least 4% (and in some cases 3%). Under certain circumstances, the appropriate banking agency may treat a well capitalized, adequately capitalized or undercapitalized institution as if the institution were in the next lower capital category.
As of December 31, 2006, Comerica and its U.S. banking subsidiaries exceeded the ratios required for an institution to be considered “well capitalized” under these regulations.
FDICIA generally prohibits a depository institution from making any capital distribution (including payment of a dividend) or paying any management fee to its holding company if the depository institution would thereafter be undercapitalized. Undercapitalized depository institutions are subject to limitations on growth and certain activities and are required to submit an acceptable capital restoration plan. The federal banking agencies may not accept a capital plan without determining, among other things, that the plan is based on realistic assumptions and is likely to succeed in restoring the depository institution’s capital. In addition, for a capital restoration plan to be acceptable, the depository institution’s parent holding company must guarantee for a specific time period that the institution will comply with such capital restoration plan. The aggregate liability of the parent holding company under the guaranty is limited to the lesser of (i) an amount equal to 5% of the depository institution’s total assets at the time it became undercapitalized, or (ii) the amount that is necessary (or would have been necessary) to bring the institution into compliance with all capital standards applicable with respect to such institution as of the time it fails to comply with the plan. If a depository institution fails to submit or implement an acceptable plan, it is treated as if it is significantly undercapitalized.
Significantly undercapitalized depository institutions are subject to a number of requirements and restrictions. Specifically, such a depository institution may be required to do one or more of the following, among other things: sell sufficient voting stock to become adequately capitalized, reduce the interest rates it pays on deposits, reduce its rate of asset growth, dismiss certain senior executive officers or directors, or stop accepting deposits from correspondent banks. Critically undercapitalized institutions are subject to the appointment of a receiver or conservator or such other action as the FDIC and the applicable federal banking agency shall determine appropriate.
FDICIA also contains a variety of other provisions that may affect the operations of depository institutions including reporting requirements, regulatory standards for real estate lending, “truth in savings” provisions, the requirement that a depository institution give 90 days prior notice to customers and regulatory authorities before closing any branch, and a prohibition on the acceptance or renewal of brokered deposits by depository institutions that are not well capitalized or are adequately capitalized and have not received a waiver from the FDIC.
Capital Requirements
Comerica and its bank subsidiaries are subject to risk-based capital requirements and guidelines imposed by the FRB and/or the OCC.
For this purpose, a depository institution’s or holding company’s assets and certain specified off-balance sheet commitments are assigned to four risk categories, each weighted differently based on the level of credit risk that is ascribed to such assets or commitments. A depository institution’s or holding company’s capital, in turn, is divided into two tiers: core (“Tier 1”) capital, which includes common equity, non-cumulative perpetual preferred stock, and a limited amount of cumulative perpetual preferred stock and related surplus (excluding auction rate issues) and minority interests in equity accounts of consolidated subsidiaries, less goodwill, certain identifiable intangible assets and certain other assets; and supplementary (“Tier 2”) capital, which includes, among other items, perpetual preferred stock not meeting the Tier 1 definition, mandatory convertible securities, subordinated debt, and allowances for loan and lease losses, subject to certain limitations, less certain required deductions.
Comerica, like other bank holding companies, currently is required to maintain Tier 1 and “total capital” (the sum of Tier 1 and Tier 2 capital) equal to at least 4% and 8% of its total risk-weighted assets (including certain off-balance-sheet items, such as standby letters of credit), respectively. At December 31, 2006, Comerica met both requirements, with Tier 1 and total capital equal to 8.02% and 11.63% of its total risk-weighted assets, respectively.
Comerica is also required to maintain a minimum “leverage ratio” (Tier 1 capital to adjusted total assets) of 3% to 5%, depending upon criteria defined and assessed by the FRB. Comerica’s leverage ratio of 9.76% at December 31, 2006 reflects the nature of Comerica’s balance sheet and demonstrates a commitment to capital adequacy.

Table of Contents

As an additional means to identify problems in the financial management of depository institutions, FDICIA requires federal bank regulatory agencies to establish certain non-capital safety and soundness standards for institutions any such agency supervises. The standards relate generally to, among others, earnings, liquidity, operations and management, asset quality, various risk and management exposures ( e.g. , credit, operational, market, interest rate, etc.) and executive compensation. The agencies are authorized to take action against institutions that fail to meet such standards.
FDIC Insurance Assessments
Comerica’s subsidiary banks are subject to FDIC deposit insurance assessments to maintain the Deposit Insurance Fund (“DIF”). As of December 31, 2006, Comerica’s banking subsidiaries held approximately $42.6 billion of DIF-assessable deposits. Comerica’s banking subsidiaries in recent years have not paid nor been assessed deposit insurance assessments on the DIF-assessable deposits under the FDIC’s risk related assessment system. The FDIC’s risk related system has been revised effective in 2007, however, and Comerica’s banking subsidiaries will be expected to begin paying annual deposit insurance assessments annually, although Comerica’s banking subsidiaries have approximately $34 million of credits to use before assessments will be expensed and paid.
Enforcement Powers of Federal Banking Agencies
The FRB and other federal banking agencies have broad enforcement powers, including the power to terminate deposit insurance, impose substantial fines and other civil penalties and appoint a conservator or receiver. Failure to comply with applicable laws or regulations could subject Comerica or its banking subsidiaries, as well as officers and directors of these organizations, to administrative sanctions and potentially substantial civil and criminal penalties.
Future Legislation
Changes to the laws of the states and countries in which Comerica and its subsidiaries do business could affect the operating environment of bank holding companies and their subsidiaries in substantial and unpredictable ways. Comerica cannot accurately predict whether such changes will occur or, if they occur, the ultimate effect they would have upon the financial condition or results of operations of Comerica.
EMPLOYEES
As of December 31, 2006, Comerica and its subsidiaries had 10,129 full-time and 1,141 part-time employees.

Item 1A. Risk Factors.
This Report includes forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. In addition, Comerica may make other written and oral communications from time to time that contain such statements. All statements regarding Comerica’s expected financial position, strategies and growth prospects and general economic conditions Comerica expects to exist in the future are forward-looking statements. The words, “anticipates,” “believes,” “feels,” “expects,” “estimates,” “seeks,” “strives,” “plans,” “intends,” “outlook,” “forecast,” “position,” “target,” “mission,” “assume,” “achievable,” “potential,” “strategy,” “goal,” “aspiration,” “outcome,” “continue,” “remain,” “maintain,” “trend,” “objective” and variations of such words and similar expressions, or future or conditional verbs such as “will,” “would,” “should,” “could,” “might,” “can,” “may” or

Table of Contents

similar expressions, as they relate to Comerica or its management, are intended to identify forward-looking statements.
Comerica cautions that forward-looking statements are subject to numerous assumptions, risks and uncertainties, which change over time. Forward-looking statements speak only as of the date the statement is made, and Comerica does not undertake to update forward-looking statements to reflect facts, circumstances, assumptions or events that occur after the date the forward-looking statements are made. Actual results could differ materially from those anticipated in forward-looking statements, and future results could differ materially from historical performance.
In addition to factors mentioned elsewhere in this Report or previously disclosed in Comerica’s SEC reports (accessible on the SEC’s website at www.sec.gov or on Comerica’s website at www.comerica.com ), the factors contained below, among others, could cause actual results to differ materially from forward-looking statements, and future results could differ materially from historical performance.
    General political, economic or industry conditions, either domestically or internationally, may be less favorable than expected.
 
      Local, domestic, and international economic, political and industry specific conditions, and governmental monetary and fiscal policies affect the financial services industry, directly and indirectly. Conditions such as inflation, recession, unemployment, volatile interest rates, tight money supply, real estate values, international conflicts and other factors outside of Comerica’s control may adversely affect Comerica. Economic downturns could result in the delinquency of outstanding loans, which could have a material adverse impact on Comerica’s earnings.
 
    Unfavorable developments concerning credit quality could adversely affect Comerica’s financial results.
 
      Although Comerica regularly reviews credit exposure related to its customers and various industry sectors in which it has business relationships, default risk may arise from events or circumstances that are difficult to detect or foresee. Under such circumstances, Comerica could experience an increase in the level of provision for credit losses, nonperforming assets, net charge-offs and reserve for credit losses, which could adversely affect Comerica’s financial results.
 
    Industries in which Comerica has lending concentrations, including, but not limited to, automotive production and the commercial real estate industry, could suffer a significant decline which could adversely affect Comerica.
 
      Comerica’s business customer base consists, in part, of lending concentrations in volatile industries such as automotive production and the commercial real estate industry. In the event of a downturn in the economy or general or further decline in any one of those industries, Comerica could experience increased credit losses, and its business could be materially adversely affected.
 
    The introductions, withdrawal, success and timing of business initiatives and strategies, including, but not limited to, the opening of new banking centers, and plans to grow personal financial services and wealth management, may be less successful or may be different than anticipated. Such a result could adversely affect Comerica’s business.
 
      Comerica makes certain projections and develops plans and strategies for its banking and financial products. If Comerica does not accurately determine demand for its banking and financial product needs, it could result in Comerica incurring significant expenses without the anticipated increases in revenue, which could result in a material adverse effect on its earnings.
 
    Fluctuations in interest rates could adversely affect Comerica’s net interest income and balance sheet.
 
      The operations of financial institutions such as Comerica are dependent to a large degree on net interest income, which is the difference between interest income from loans and investments and interest expense on deposits and borrowings. Prevailing economic conditions, the fiscal and monetary policies of the federal government and the policies of various regulatory agencies all affect market rates of interest, which in turn

Table of Contents

      significantly affect financial institutions’ net interest income. Fluctuations in interest rates affect Comerica’s balance sheet, as they do for all financial institutions. Volatility in interest rates can also result in disintermediation, which is the flow of funds away from financial institutions into direct investments, such as federal government and corporate securities and other investment vehicles, which, because of the absence of federal insurance premiums and reserve requirements, generally pay higher rates of return than financial institutions. Fluctuations in interest rates could materially adversely affect Comerica’s net interest income and balance sheet.
 
    Customer borrowing, repayment, investment and deposit practices generally may be different than anticipated.
 
      Comerica uses a variety of financial tools, models and other methods to anticipate customer behavior as a part of its strategic planning and to meet certain regulatory requirements. Individual, economic, political, industry-specific conditions and other factors outside of Comerica’s control could alter predicted customer borrowing, repayment, investment and deposit practices. Such a change in these practices could materially adversely affect Comerica’s ability to anticipate business needs and meet regulatory requirements.
 
    Management’s ability to maintain and expand customer relationships may differ from expectations.
 
      The financial services industry is very competitive. Comerica not only vies for business opportunities with new customers, but also competes to maintain and expand the relationships it has with its existing customers. While management believes that it can continue to grow many of these relationships, Comerica will continue to experience pressures to maintain these relationships as its competitors attempt to capture its customers. Failure to create new customer relationships and to maintain and expand existing customer relationships to the extent anticipated may adversely impact Comerica’s earnings.
 
    Competitive product and pricing pressures among financial institutions within Comerica’s markets may change.
 
      Comerica operates in a very competitive environment, which is characterized by competition from a number of other financial institutions in each market in which it operates. Comerica competes with large national and regional financial institutions and with smaller financial institutions in terms of products and pricing. If Comerica is unable to compete effectively in products and pricing in its markets, business could decline, which could have a material adverse effect on Comerica’s business, financial condition or results of operations.
 
    Management’s ability to retain key officers and employees may change.
 
      Comerica’s future operating results depend substantially upon the continued service of Comerica’s executive officers and key personnel. Comerica’s future operating results also depend in significant part upon Comerica’s ability to attract and retain qualified management, financial, technical, marketing, sales and support personnel. Competition for qualified personnel is intense, and Comerica cannot ensure success in attracting or retaining qualified personnel. There may be only a limited number of persons with the requisite skills to serve in these positions, and it may be increasingly difficult for Comerica to hire personnel over time. Comerica’s business, financial condition or results of operations could be materially adversely affected by the loss of any of its key employees, by the failure of any key employee to perform in his or her current position, or by Comerica’s inability to attract and retain skilled employees.
 
    Legal and regulatory proceedings and related matters with respect to the financial services industry, including those directly involving Comerica and its subsidiaries, could adversely affect Comerica or the financial services industry in general.
 
      Comerica has been, and may in the future be, subject to various legal and regulatory proceedings. It is inherently difficult to assess the outcome of these matters, and there can be no assurance that Comerica will prevail in any proceeding or litigation. Any such matter could result in substantial cost and diversion of Comerica’s efforts, which by itself could have a material adverse effect on Comerica’s financial condition and operating results. Further, adverse determinations in such matters could result in actions by Comerica’s

9


Table of Contents

      regulators that could materially adversely affect Comerica’s business, financial condition or results of operations.
 
    Changes in regulation or oversight may have a material adverse impact on Comerica’s operations.
 
      Comerica is subject to extensive regulation, supervision and examination by the Michigan Office of Financial and Insurance Services, the Federal Deposit Insurance Corporation, the Board of Governors of the Federal Reserve System, the Securities and Exchange Commission and other regulatory bodies. Such regulation and supervision governs the activities in which Comerica may engage. Regulatory authorities have extensive discretion in their supervisory and enforcement activities, including the imposition of restrictions on Comerica’s operations, investigations and limitations related to Comerica’s securities, the classification of Comerica’s assets and determination of the level of Comerica’s allowance for loan losses. Any change in such regulation and oversight, whether in the form of regulatory policy, regulations, legislation or supervisory action, may have a material adverse impact on Comerica’s business, financial condition or results of operations.
 
    Methods of reducing risk exposures might not be effective.
 
      Instruments, systems and strategies used to hedge or otherwise manage exposure to various types of credit, market and liquidity, operational, compliance, business risks and enterprise-wide risk could be less effective than anticipated. As a result, Comerica may not be able to effectively mitigate its risk exposures in particular market environments or against particular types of risk, which could have a material adverse impact on Comerica’s business, financial condition or results of operations.
 
    There could be terrorist activities or other hostilities, which may adversely affect the general economy, financial and capital markets, specific industries, and Comerica.
 
      Terrorist attacks or other hostilities may disrupt Comerica’s operations or those of its customers. In addition, these events have had and may continue to have an adverse impact on the U.S. and world economy in general and consumer confidence and spending in particular, which could harm Comerica’s operations. Any of these events could increase volatility in the U.S. and world financial markets, which could harm Comerica’s stock price and may limit the capital resources available to its customers and Comerica. This could have a material adverse impact on Comerica’s operating results, revenues and costs and may result in increased volatility in the market price of Comerica’s common stock.
 
    There could be natural disasters, including, but not limited to, hurricanes, tornadoes, earthquakes, fires and floods, which may adversely affect the general economy, financial and capital markets, specific industries, and Comerica.
 
      Comerica has significant operations and a significant customer base in California, Texas, Florida and other regions where natural disasters may occur. These regions are known for being vulnerable to natural disasters and other risks, such as tornadoes, hurricanes, earthquakes, fires and floods. These types of natural disasters at times have disrupted the local economy, Comerica’s business and customers and have posed physical risks to Comerica’s property. A significant natural disaster could materially adversely affect Comerica’s operating results.
Item 1B. Unresolved Staff Comments.
None.
Item 2. Properties.
The executive offices of Comerica are located in the Comerica Tower at Detroit Center, 500 Woodward Avenue, Detroit, Michigan 48226. Comerica and its subsidiaries currently occupy 11 floors of the building, which is leased through Comerica Bank from an unaffiliated third party. The leases at this building extend through January 2012. As of December 31, 2006, Comerica, through its banking affiliates, operated a total of 461 banking centers, trust

services locations, and loan production or other financial services offices, primarily in the States of Michigan, California, Texas and Florida. Of these offices, 225 were owned and 236 were leased. As of December 31, 2006, affiliates also operated from leased spaces in Mesa and Phoenix, Arizona; Denver, Colorado; Wilmington, Delaware; Barrington, Chicago and Oakbrook Terrace, Illinois; Boston and Waltham, Massachusetts; Minneapolis, Minnesota; Princeton and Sea Girt, New Jersey; Las Vegas, Nevada; New York, New York; Rocky Mount, North Carolina; Cleveland and West Chester, Ohio; Memphis, Tennessee; Reston, Virginia; Bellevue and Seattle, Washington; Monterey, Mexico; Wanchai, Hong Kong; Toronto, Ontario, Canada and Windsor, Ontario, Canada.
Comerica and its subsidiaries own, among other properties, a check processing center in Livonia, Michigan, a 10-story building in the central business district of Detroit, Michigan that houses certain departments of Comerica and Comerica Bank, and three buildings in Auburn Hills, Michigan, used mainly for lending functions and operations.
Item 3. Legal Proceedings.
Comerica and certain of its subsidiaries are subject to various pending and threatened legal proceedings arising out of the normal course of business or operations. In view of the inherent difficulty of predicting the outcome of such matters, Comerica cannot state what the eventual outcome of any such matters will be. However, based on current knowledge and after consultation with legal counsel, management believes that current reserves, determined in accordance with SFAS No. 5, “Accounting for Contingencies,” are adequate and the amount of any incremental liability arising from these matters is not expected to have a material adverse effect on Comerica’s consolidated financial condition or results of operations.
Item 4. Submission of Matters to a Vote of Security Holders.
Comerica did not submit any matters for a shareholders’ vote in the fourth quarter of 2006.

Under the Long-Term Incentive Plan, not more than a total of 2.2 million shares may be used for awards other than options and stock appreciation rights and not more than one million shares are available as incentive stock options. Further, no award recipient may receive more than 350,000 shares during any calendar year, and the maximum number of shares underlying awards of options and stock appreciation rights that may be granted to an award recipient in any calendar year is 350,000.

Table of Contents

Amended and Restated Comerica Incorporated Stock Option Plan for Non-Employee Directors of Comerica Bank and Affiliated Banks (Terminated March 2004) — Under the plan, Comerica granted options to acquire up to 450,000 shares of common stock, subject to equitable adjustment upon the occurrence of events such as stock splits, stock dividends or recapitalizations. After each annual meeting of shareholders, each member of the Board of Directors of a subsidiary bank of Comerica who was not an employee of Comerica or of any of its subsidiaries nor a director of Comerica (the “Eligible Directors”) automatically was granted an option to purchase 2,500 shares of the common stock of Comerica. Option grants under the plan were in addition to annual retainers, meeting fees and other compensation payable to Eligible Directors in connection with their services as directors. The plan is administered by a committee of the Board of Directors. With respect to the automatic grants, the Committee does not and did not have discretion as to matters such as the selection of directors to whom options will be granted, the timing of grants, the number of shares to become subject to each option grant, the exercise price of options, or the periods of time during which any option may be exercised. In addition to the automatic grants, the committee could grant options to the Eligible Directors in its discretion. The exercise price of each option granted was the fair market value of each share of common stock subject to the option on the date the option was granted. The exercise price is payable in full upon exercise of the option and may be paid in cash or by delivery of previously owned shares. The committee may change the option price per share following a corporate reorganization or recapitalization so that the aggregate option price for all shares subject to each outstanding option prior to the change is equivalent to the aggregate option price for all shares or other securities into which option shares have been converted or which have been substituted for option shares. The term of each option cannot be more than ten years. This plan was terminated by the Board of Directors on March 23, 2004. Accordingly, no new options may be granted under this plan.
Director Deferred Compensation Plans — Comerica maintains two deferred compensation plans for non-employee directors of Comerica, its subsidiaries and its advisory boards: the Amended and Restated Comerica Incorporated Common Stock Non-Employee Director Fee Deferral Plan (the “Common Stock Deferral Plan”) and the Amended and Restated Comerica Incorporated Non-Employee Director Fee Deferral Plan (the “Director Fee Deferral Plan”). The Common Stock Deferral Plan allows directors to invest in units that correlate to, and are functionally equivalent to, shares of common stock of Comerica, while the Director Fee Deferral Plan allows directors to invest in units that correlate to, and are functionally equivalent to, the shares of certain mutual funds offered under such plan. The Common Stock Deferral Plan previously provided for the mandatory deferral of 50% of the annual retainer of each director of Comerica into shares of common stock of Comerica, but currently has no mandatory deferral. Until the mandatory deferral requirement was discontinued, directors could voluntarily defer the remaining 50% of their director fees (and all other non-employee directors of Comerica’s subsidiaries could choose to defer up to 100% of their director fees) under the Common Stock Deferral Plan or the Director Fee Deferral Plan, or a combination of the two plans. Currently, all eligible non-employee directors may defer any portion or none of their director fees under the Common Stock Deferral Plan or the Director Fee Deferral Plan, or a combination of the two plans.
The directors’ accounts under the Common Stock Deferral Plan are increased to the extent of dividends paid on Comerica common stock to reflect the number of additional shares of Comerica’s common stock that could have been purchased had the dividends been paid on each share of common stock underlying then-outstanding stock units in the directors’ accounts. Similarly, the directors’ accounts under the Director Fee Deferral Plan are increased in connection with the payment of dividends paid on the mutual fund shares to reflect the number of additional shares of mutual fund shares that could have been purchased had the dividends or other distributions been paid on each share of stock underlying then-outstanding mutual fund units in the directors’ accounts. Following the applicable deferral period, the distribution of a participant’s Comerica stock unit account under the Common Stock Deferral Plan is made in Comerica’s common stock (with fractional shares being paid in cash), while the distribution of a participant’s mutual fund account under the Director Fee Deferral Plan is made in cash.
Employee Deferred Compensation Plans — Comerica maintains two deferred compensation plans for eligible employees of Comerica and its subsidiaries: the 1999 Comerica Incorporated Amended and Restated Common Stock Deferred Incentive Award Plan (the “Employee Common Stock Deferral Plan”) and the 1999 Comerica Incorporated Deferred Compensation Plan (the “Employee Deferral Plan”). Under the Employee Common Stock Deferral Plan, eligible employees may defer specified portions of their incentive awards into units that correlate to, and are functionally equivalent to, shares of common stock of Comerica. The employees’ accounts under the Employee Common Stock Deferral Plan are increased in connection with the payment of dividends paid on Comerica’s common stock to reflect the number of additional shares of Comerica’s common stock that could have been purchased had the dividends been paid on each share of common stock underlying then-outstanding stock units

in the employees’ accounts. The deferred compensation under the Employee Common Stock Deferral Plan is payable in shares of Comerica’s common stock following termination of service as an employee.
Similarly, under the Employee Deferral Plan, eligible employees may defer specified portions of their compensation, including salary, bonus and incentive awards, into units that correlate to, and are functionally equivalent to, shares of funds offered under the Employee Deferral Plan. Beginning in 1999, no such funds are Comerica stock funds. The employees’ accounts under the Employee Deferral Plan are increased in connection with the payment of dividends paid on the fund shares to reflect the number of additional shares of the fund stock that could have been purchased had the dividends been paid on each share of fund stock underlying then-outstanding stock units in the employees’ accounts. The deferred compensation under the Employee Deferral Plan is payable in cash following termination of service as an employee.
For additional information regarding Comerica’s equity compensation plans, please refer to Note 15 on pages 92 through 94 of the Consolidated Financial Statements contained in Comerica’s Annual Report to Shareholders for the year ended December 31, 2006.
Purchases of Equity Securities by the Issuer and Affiliated Purchasers
The Board of Directors of the Corporation (the “Board”) authorized the purchase of up to 10 million shares of Comerica Incorporated outstanding common stock on July 26, 2005 and an additional 10 million shares on November 14, 2006. Substantially all shares purchased as part of Comerica’s publicly announced repurchase program were transacted in the open market and were within the scope of Rule 10b-18, which provides a safe harbor for purchases in a given day if an issuer of equity securities satisfies the manner, timing, price and volume conditions of the rule when purchasing its own common shares in the open market. There is no expiration date for Comerica’s share repurchase program. The following table summarizes Comerica’s share repurchase activity for the quarter ended December 31, 2006.

Exhibit 10.1
COMERICA INCORPORATED
2006 AMENDED AND RESTATED LONG-TERM INCENTIVE PLAN
SECTION 1. Purpose .
          The purpose of Comerica’s 2006 Long-Term Incentive Plan is to align the interests of employees of the Corporation selected to receive awards with those of stockholders by rewarding long term decision-making and actions for the betterment of the Corporation. Accordingly, Eligible Individuals may receive Awards of Options, Stock Appreciation Rights, Restricted Stock or Restricted Stock Units, Performance Awards and Other Stock-Based Awards. Equity-based compensation assists in the attraction and retention of qualified employees, and provides them with additional incentive to devote their best efforts to pursue and sustain the Corporation’s superior long-term performance. This enhances the value of the Corporation for the benefit of its stockholders.
SECTION 2. Definitions .
     A. “ Affiliate ” means (i) any entity that is controlled by the Corporation, whether directly or indirectly, and (ii) any entity in which the Corporation has a significant equity interest, as determined by the Committee.
     B. “ Award ” means an Option, a Stock Appreciation Right, a Share of Restricted Stock, a Restricted Stock Unit, a Performance Award, including a Qualified Performance-Based Award, or an Other Stock-Based Award pursuant to the Plan. Each Award shall be evidenced by an Award Agreement.
     C. “ Award Agreement ” means a written agreement, in a form approved by the Committee, which sets forth the terms and conditions of an Award, including, but not limited to, the Performance Period and/or Restriction Period, as appropriate. Agreements shall be subject to the express terms and conditions set forth herein, and to such other terms and conditions not inconsistent with the Plan as the Committee shall deem appropriate.
     D. “ Award Recipient ” means an Eligible Individual who has been granted an Award under the Plan and has entered into an Award Agreement evidencing the grant of such Award or otherwise accepted the terms of an Award Agreement, including by electronic acceptance or acknowledgement.
     E. “ Beneficiary ” means any person(s) designated by an Award Recipient on a beneficiary designation form, or, if no form, any person(s) entitled to receive any amounts owing to such Award Recipient under this Plan upon his or her death by reason of having been named in the Award Recipient’s will or trust agreement or having qualified as a taker of the Award Recipient’s property under the laws of intestacy. If an Award Recipient authorizes any person, in writing, to exercise such individual’s Options or Stock Appreciation Rights following the Award Recipient’s death, the term “Beneficiary” shall include any person in whose favor such Options or Stock Appreciation Rights are exercised by the person authorized to exercise the Options or Stock Appreciation Rights.

 


 

     F. “ Board ” means the Board of Directors of the Corporation.
     G. “ Cause ” means (1) conviction of the Award Recipient for committing a felony under Federal law or the law of the state in which such action occurred, (2) dishonesty in the course of fulfilling the Award Recipient’s employment duties, (3) willful and deliberate failure on the part of the Award Recipient to perform his or her employment duties in any material respect, or (4) before a Change of Control, such other events as shall be determined by the Committee. Before a Change of Control, the Committee shall, unless otherwise provided in an Individual Agreement with the Award Recipient, have the sole discretion to determine whether “Cause” exists, and its determination shall be final.
     H. “ Change of Control ” shall have the meaning set forth in Exhibit A to this Plan.
     I. “ Code ” means the Internal Revenue Code of 1986, as amended, and the regulations thereunder.
     J. “ Committee ” means the Compensation Committee of the Board or such other committee of the Board as the Board may from time to time designate, which shall be composed of not less than two non-employee directors, and shall be appointed by and serve at the pleasure of the Board.
     K. “ Corporation ” means Comerica Incorporated, a Delaware corporation, and its successors and assigns.
     L. “ Disabled ” or “ Disability ” means “ Totally Disabled ” (or any derivation of such term) within the meaning of the Long-Term Disability Plan of Comerica Incorporated, or if there is no such plan, “Disability” as determined by the Committee. However, with respect to the rules relating to Incentive Stock Options, the term “Disabled” shall mean disabled as that term is utilized in Sections 422 and 22(e)(3) of the Code, or any successor Code provisions relating to ISOs.
     M. “ Disaffiliation ” means a Subsidiary’s or Affiliate’s ceasing to be a Subsidiary or Affiliate for any reason (including, without limitation, as a result of a public offering, or a spinoff or sale by the Corporation, of the stock of the Subsidiary or Affiliate) or a sale of a division of the Corporation and its Affiliates.
     N. “ Eligible Individual ” means any officers and employees of the Corporation or any of its Subsidiaries or Affiliates, and prospective officers and employees who have accepted offers of employment from the Corporation or its Subsidiaries or Affiliates. Notwithstanding the foregoing, an Eligible Individual for purposes of receipt of the grant of an ISO shall be limited to those individuals who are eligible to receive ISOs under rules set forth in the Code and applicable regulations.
     O. “ Exchange Act ” means the Securities Exchange Act of 1934, as amended.
     P. “ Fair Market Value ” means the closing price of a Share on the New York Stock Exchange as reported on the Composite Tape as published in the Wall Street Journal ; if, however, there is no trading of Shares on the date in question, then the closing price of the

2

In the case of Corporate Transactions, such adjustments may include, without limitation, (1) the cancellation of outstanding Awards in exchange for payments of cash, property or a combination thereof having an aggregate value equal to the value of such Awards, as determined by the Committee or the Board in its sole discretion (it being understood that in the case of a Corporate Transaction with respect to which stockholders of Common Stock receive consideration other than publicly traded equity securities of the ultimate surviving entity, any such determination by the Committee that the value of an Option or Stock Appreciation Right shall for this purpose be deemed to equal the excess, if any, of the value of the consideration being paid for each Share pursuant to such Corporate Transaction over the exercise price of such Option or Stock Appreciation Right shall conclusively be deemed valid); (2) the substitution of other property (including, without limitation, cash or other securities of the Corporation and securities of entities other than the Corporation) for the Shares subject to outstanding Awards; and (3) in connection with any Disaffiliation, arranging for the assumption of Awards, or replacement of Awards with new awards based on other property or other securities (including, without limitation, other securities of the Corporation and securities of entities other than the Corporation), by the affected Subsidiary, Affiliate, or division or by the entity that controls such Subsidiary, Affiliate, or division following such Disaffiliation (as well as any corresponding adjustments to Awards that remain based upon Corporation securities). Any such adjustments shall be made in a manner that (i) with respect to Awards that are not considered to be deferred compensation within the meaning of Section 409A of the Code as of immediately prior to such adjustment, would not cause such Awards to become deferred compensation subject to Section 409A of the Code and (ii) with respect to Awards that are considered deferred compensation within the meaning of Section 409A of the Code, would not cause such Awards to be non-compliant with the requirements of Section 409A of the Code.

SECTION 4. Administration .
     A.  Committee . The Plan shall be administered by the Committee. In addition to any implied powers and duties that may be needed to carry out the provisions of the Plan, the Committee shall have all the powers vested in it by the terms of the Plan, including exclusive authority to: select Eligible Individuals; to make Awards; to determine the type, size, terms and timing of Awards (which need not be uniform); to accelerate the vesting of Awards, including upon the occurrence of a Change of Control of the Corporation or an Award Recipient’s Termination of Employment; to prescribe the form of the Award Agreement; to modify, amend or adjust the terms and conditions of any Award, subject to Sections 7 and 10; to adopt, alter and repeal such administrative rules, guidelines and practices governing the Plan as it shall from time to time deem advisable; to interpret the terms and provisions of the Plan and any Award issued under the Plan (and any Award Agreement relating thereto); make any other determinations it believes necessary or advisable in connection with the administration of the Plan; correct any defect, supply any omission or reconcile any inconsistency in the Plan or in any Award Agreement; establish any “blackout” period that the Committee in its sole discretion deems necessary or advisable; and to otherwise administer the Plan.
     B.  Procedures . Determinations of the Committee shall be made by a majority vote of its members at a meeting at which a quorum is present or pursuant to a unanimous written consent of its members.

Any such allocation or delegation may be revoked by the Committee at any time.
          All decisions made by the Committee (or any person or persons to whom the Committee has allocated or delegated all or any portion of its responsibilities and powers in accordance with this Plan) shall be final and binding on all persons, including the Corporation, its Affiliates, Subsidiaries, stockholders, Eligible Individuals, Award Recipients, Beneficiaries and other interested parties.

Subject to Section 1(G), any determination made by the Committee or by an appropriately delegated officer pursuant to delegated authority under the provisions of the Plan with respect to any Award shall be made in the sole discretion of the Committee or such delegate at the time of the grant of the Award or, unless in contravention of

7


 

any express term of the Plan, at any time thereafter. All decisions made by the Committee or any appropriately delegated officer pursuant to the provisions of the Plan shall be final and binding on all persons, including the Corporation, Award Recipients and Eligible Individuals.

Any such suspension of an Award shall remain in effect until the suspension shall be presented to and acted on by the Committee at its next meeting. This Section 4(D) shall have no application for a two year period following a Change of Control of the Corporation.

     (a) Retirement . An Award Recipient’s Retirement shall not affect any Option outstanding as of the Termination of Employment due to Retirement other than those granted in the calendar year of Retirement. All Options outstanding as of the Termination of Employment due to Retirement other than those granted in the calendar year of such Termination of Employment shall continue to vest pursuant to the vesting schedule applicable to such Options, and any vested Options outstanding as of the Termination of Employment due to Retirement (including any ISO held by an Award Recipient who is not Disabled) shall continue in full force and effect for the remainder of the Term of the Option.

     (d) Other Terminations of Employment .

Further, with respect to ISOs, as a condition of any such extension, the holder shall be required to deliver to the Corporation a release which provides that such individual will hold the Corporation and/or Affiliate harmless with respect to any adverse tax consequences the individual may suffer by reason of any such extension.

A Stock Appreciation Right granted under the Plan shall confer on the Award Recipient a right to receive upon exercise thereof the excess (if any) of (i) the Fair Market Value of one Share on the date of exercise over (ii) the grant price of the Stock Appreciation Right Award as specified by the Committee, which price shall not be less than 100% of the Fair Market Value of one Share on the date of grant of the Stock Appreciation Right. Subject to the terms of the Plan, the Committee shall determine the grant price, Term, manner of exercise, dates of exercise, methods of settlement (cash, Shares or a combination thereof) and any other terms and conditions of any SAR Award. The Committee may impose such conditions or restrictions on the exercise of any SAR Award as it may deem appropriate. Except as otherwise provided by the Committee or in an Award Agreement, any SAR Award must be exercised during the period of the Award Recipient’s employment with the Corporation or Affiliate, provided that the provisions of Section 6(A)(4)(a)-(e) hereof shall apply for purposes of determining the exercise period in the event of the Award Recipient’s Retirement, Disability, death or other Termination of Employment, including following a Change of Control.

Subject to the Committee’s authority under Section 6(C)(3) below, the minimum Restriction Period with respect to a Restricted Stock Award that is subject to restrictions that are performance-related shall be one (1) year, and the minimum Restriction Period with respect to a Restricted Stock Award that is subject to restrictions that are not performance-related shall be three (3) years.

Shares comprising any Restricted Stock Award held by the Corporation that are no longer subject to restrictions shall be delivered to the Award Recipient (or his or her Beneficiary) promptly after the applicable restrictions lapse or are waived.
     D.  Restricted Stock Unit Awards . The Committee may grant Awards of Restricted Stock Units to Eligible Individuals, subject to such terms and conditions, not inconsistent with the provisions of the Plan, as the Committee shall determine to be appropriate. A Restricted Stock Unit shall represent an unfunded, unsecured right to receive one Share or cash equal to the Fair Market Value of a Share.
     (1) Nature of Restrictions . Restricted Stock Unit Awards shall be subject to such restrictions, including Performance Measures, as the Committee may impose, which restrictions may lapse separately or in combination at such time or times, in such installments or otherwise as the Committee may deem appropriate. Subject to the Committee’s authority under Section 6(D)(3) below, the minimum Restriction Period with respect to a Restricted Stock Unit Award that is subject to restrictions that are performance-related shall be one (1) year, and the minimum Restriction Period with respect to a Restricted Stock Unit Award that is subject to restrictions that are not performance-related shall be three (3) years. The Committee may, prior to or at the time of grant, designate an Award of Restricted Stock as a Qualified Performance-Based Award.
     (2) Rights as a Stockholder . An Eligible Individual to whom Restricted Stock Units are granted shall not have any rights of a stockholder of the Corporation with respect to the Share represented by the Restricted Stock Unit Award. If so determined by the Committee, in its sole and absolute discretion, Restricted Stock Units may include a dividend equivalent right, pursuant to which the Award Recipient will either receive cash amounts (either paid currently or on a contingent basis) equivalent to the dividends and other distributions payable with respect to the number of Shares represented by the Restricted Stock Units, or additional Restricted Stock Units with a Fair Market Value equal to such dividends and other distributions.
     (3) Forfeiture/Settlement . Except as may be otherwise provided in an Award Agreement, upon an Award Recipient’s Termination of Employment (as determined

11


 

under criteria established by the Committee) during the applicable Restriction Period, all Restricted Stock Units shall be immediately forfeited; provided, however , that the Committee may waive, in whole or in part, any or all remaining vesting requirements or restrictions applicable to the Restricted Stock Unit Award. An Award of Restricted Stock Units shall be settled in Shares as and when the Restricted Stock Units vest or at a later time specified by the Committee or in accordance with an election of the Award Recipient, if the Committee so permits.
     E.  Performance Awards . The Committee may grant Performance Awards (designated as Qualified Performance-Based Awards or not) to Eligible Individuals in accordance with the provisions of this Section 6(E) subject to such additional terms and conditions, not inconsistent with the provisions of the Plan, as the Committee shall determine to be appropriate.

Subject to the terms of the Plan and any applicable Award Agreement, the Performance Measures to be achieved during any Performance Period, the length of any Performance Period and the amount of any payment or number of Shares in respect of a Performance Award shall be determined by the Committee.
     F.  Other Stock-Based Awards . The Committee may grant Other Stock-Based Awards to Eligible Individuals in accordance with the provisions of this Section 6(F) and subject to such additional terms and conditions, including Performance Measures, not inconsistent with the provisions of the Plan, as the Committee shall determine.

     G.  General . Except as otherwise specified in the Plan or an applicable Award Agreement, the following provisions shall apply to Awards granted under the Plan:
     (1) Consideration for Awards . Other than the payment of the exercise price or grant price in connection with the exercise of an Option or Stock Appreciation Right or in connection with a deferral, Awards shall be made without monetary consideration or for such minimal monetary consideration as may be required by applicable law. In no event may any Option or Stock Appreciation Right granted under this Plan be amended, other than pursuant to Section 3(D), to decrease the exercise or grant price thereof, be cancelled in conjunction with the grant of any new Option or Stock Appreciation Right with a lower exercise or grant price, or otherwise be subject to any action that would be treated, for accounting purposes, as a “repricing” of such Option or Stock Appreciation Right, unless such amendment, cancellation, or action is approved by the Corporation’s stockholders.
     (2) Forms of Payment under Awards . Subject to the terms of the Plan and of any applicable Award Agreement, payments or transfers of Shares to be made by the Corporation or an Affiliate upon the grant, exercise or satisfaction of an Award may be

12


 

made in such form or forms as the Committee shall determine (including, without limitation, cash, Shares, other securities, other Awards or other property or any combination thereof), and may be made in a single payment or transfer, in installments or an a deferred basis subject to Section 409A of the Code, to the extent permitted by the applicable Award Agreement and in each case in accordance with rules and procedures established by the Committee. Such rules and procedures may include, without limitation, provisions for the payment or crediting of reasonable interest on installment or deferred payments.
     (3) Limits on Transfer of Awards . No Award and no right under any such Award shall be transferable by an Award Recipient otherwise than by will or by the laws of intestacy; provided, however , that, an Award Recipient may, in the manner established by the Committee, designate a Beneficiary to exercise the rights of the Award Recipient and to receive any property distributable with respect to any Award upon the death of the Award Recipient. Each Award or right under any Award shall be exercisable during the Award Recipient’s lifetime only by the Award Recipient or, if permissible under applicable law, by the Award Recipient’s guardian or legal representative. No Award or right under any such Award may be pledged, alienated, attached or otherwise encumbered, and any purported pledge, alienation, attachment or encumbrance thereof shall be void and unenforceable against the Corporation or any Affiliate.
     (4) Term of Awards . Subject to any specific provisions of the Plan, the term of each Award shall be for such period as may be determined by the Committee.
     (5) Securities Law Restrictions . All certificates for Shares or other securities delivered under the Plan pursuant to any Award or the exercise thereof shall be subject to such restrictions as the Committee may deem advisable under the Plan, or the rules, regulations and other requirements of the Securities and Exchange Commission, the New York Stock Exchange, any other exchange on which Shares may be eligible to be traded or any applicable federal or state securities laws, and the Committee may cause a legend or legends to be placed on any such certificates to make appropriate reference to such restrictions.
SECTION 7. Qualified Performance-Based Awards
     A.  Section 162(m) Exemption . The provisions of this Plan are intended to ensure that all Options and Stock Appreciation Rights granted hereunder to any Award Recipient who is or may be a “covered employee” (within the meaning of Section 162(m)(3) of the Code) in the tax year in which such Option or Stock Appreciation Right is expected to be deductible to the Corporation qualify for the Section 162(m) Exemption, and all such Awards shall therefore be considered Qualified Performance-Based Awards and this Plan shall be interpreted and operated consistent with that intention (including, without limitation, to require that all such Awards be granted by a committee composed solely of members who satisfy the requirements for being “outside directors” for purposes of the Section 162(m) Exemption (“ Outside Directors ”)). When granting any Award other than an Option or Stock Appreciation Right, the Committee may designate such Award as a Qualified Performance-Based Award, based upon a determination that (i) the recipient is or may be a “covered employee” (within the meaning of Section

13


 

162(m)(3) of the Code) with respect to such Award, and (ii) the Committee wishes such Award to qualify for the Section 162(m) Exemption, and the terms of any such Award (and of the grant thereof) shall be consistent with such designation (including, without limitation, that all such Awards be granted by a committee composed solely of Outside Directors).
     B.  Limitation on Amendment . Each Qualified Performance-Based Award (other than an Option or Stock Appreciation Right) shall be earned, vested and payable (as applicable) only upon the achievement of one or more Performance Measure, together with the satisfaction of any other conditions, such as continued employment, as the Committee may determine to be appropriate, and no Qualified Performance-Based Award may be amended, nor may the Committee exercise any discretionary authority it may otherwise have under this Plan with respect to a Qualified Performance-Based Award, in any manner that would cause the Qualified Performance-Based Award to cease to qualify for the Section 162(m) Exemption; provided, however , that (i) the Committee may provide, either in connection with the grant of the applicable Award or by amendment thereafter, that achievement of such Performance Measure will be waived upon the death or Disability of the Participant (or under any other circumstance with respect to which the existence of such possible waiver will not cause the Award to fail to qualify for the Section 162(m) Exemption), and (ii) any rights to vesting or accelerated payment on a Change of Control shall apply notwithstanding this Section 7(B).
     C.  Maximum Cash Award . For purposes of the Section 162(m) Exemption, the maximum amount of compensation payable with respect to an Award granted under the Plan to any Award Recipient who is a “covered employee” (as defined in Section 162(m) of the Code) that is denominated as a dollar amount will not exceed $5,000,000 for any calendar year.
     D.  Limitation on Action by the Full Board . The full Board shall not be permitted to exercise authority granted to the Committee to the extent that the grant or exercise of such authority would cause an Award designated as a Qualified Performance-Based Award not to qualify for, or to cease to qualify for, the Section 162(m) Exemption.
SECTION 8. Section 409A of the Code .
          It is the intention of the Corporation that no Award shall be “deferred compensation” subject to Section 409A of the Code, unless and to the extent that the Committee specifically determines otherwise as provided below, and the Plan and the terms and conditions of all Awards shall be interpreted accordingly. The terms and conditions governing any Awards that the Committee determines will be subject to Section 409A of the Code, including any rules for elective or mandatory deferral of the delivery of cash or Shares pursuant thereto and any rules regarding treatment of such Awards in the event of a Change of Control, shall be set forth in the applicable Award Agreement, and shall comply in all respects with Section 409A of the Code.
SECTION 9. Withholding of Taxes .
          The Corporation will, if required by applicable law, withhold the minimum statutory amount of Federal, state and/or local withholding taxes no later than the date as of which an amount first becomes includible in the gross income of an Award Recipient for Federal, state, local or foreign income or employment or other tax. Unless otherwise provided in

14


 

the applicable Award Agreement, each Award Recipient may satisfy any such tax withholding obligation by any of the following means, or by a combination of such means: (i) a cash payment; (ii) by delivery to the Corporation of already-owned Shares which have been held by the individual for at least six (6) months having a Fair Market Value, as of the Tax Withholding Date, sufficient to satisfy the amount of the withholding tax obligation arising from an exercise or vesting of an Award; (iii) by authorizing the Corporation to withhold from the Shares otherwise issuable to the individual pursuant to the exercise or vesting of an Award, a number of shares having a Fair Market Value, as of the Tax Withholding Date, which will satisfy the amount of the withholding tax obligation; or (iv) by a combination of such methods of payment. If the amount requested is not paid, the Corporation may refuse to satisfy the Award. The obligations of the Corporation under the Plan shall be conditional on such payment or arrangements, and the Corporation and its Affiliates shall, to the extent permitted by law, have the right to deduct any such taxes from any payment otherwise due to such Award Recipient. The Committee may establish such procedures as it deems appropriate, including making irrevocable elections, for the settlement of withholding obligations with Shares.
SECTION 10. Amendment and Termination .
     A.  Amendments to the Plan . The Committee may amend, alter, or discontinue the Plan, but no amendment, alteration or discontinuation shall be made which would materially impair the rights of the Award Recipients with respect to a previously granted Award without such Award Recipient’s consent, except such an amendment made to comply with applicable law, including without limitation Section 409A of the Code, stock exchange rules or accounting rules. In addition, no such amendment shall be made without the approval of the Corporation’s stockholders to the extent such approval is required by applicable law or the listing standards of the applicable stock exchange.
     B.  Amendments to Awards . Subject to Section 6(G)(1), the Committee may unilaterally amend the terms of any Award theretofore granted, but no such amendment shall cause a Qualified Performance-Based Award to cease to qualify for the Section 162(m) Exemption or without the Award Recipient’s consent materially impair the rights of any Award Recipient with respect to an Award, except such an amendment made to cause the Plan or Award to comply with applicable law, stock exchange rules or accounting rules.
SECTION 11. Miscellaneous Provisions .
     A.  Conditions for Issuance . The Committee may require each person purchasing or receiving Shares pursuant to an Award to represent to and agree with the Corporation in writing that such person is acquiring the Shares without a view to the distribution thereof. The certificates for such Shares may include any legend which the Committee deems appropriate to reflect any restrictions on transfer. Notwithstanding any other provision of the Plan or Award Agreements made pursuant thereto, the Corporation shall not be required to issue or deliver any certificate or certificates for Shares under the Plan prior to fulfillment of all of the following conditions: (i) listing or approval for listing upon notice of issuance, of such Shares on the applicable stock exchange; (ii) any registration or other qualification of such Shares of the Corporation under any state or Federal law or regulation, or the maintaining in effect of any such registration or other qualification which the Committee shall, in its absolute discretion upon the

15


 

advice of counsel, deem necessary or advisable; and (iii) obtaining any other consent, approval, or permit from any state or Federal governmental agency which the Committee shall, in its absolute discretion after receiving the advice of counsel, determine to be necessary or advisable.
     B.  Additional Compensation Arrangements . Nothing contained in the Plan shall prevent the Corporation or any Subsidiary or Affiliate from adopting other or additional compensation arrangements for its employees. Participation in the Plan shall not affect an individual’s eligibility to participate in any other benefit or incentive plan of the Corporation.
     C.  No Contract of Employment or Rights to Awards . The Plan shall not constitute a contract of employment, and adoption of the Plan shall not confer upon any employee any right to continued employment, nor shall it interfere in any way with the right of the Corporation or any Subsidiary or Affiliate to terminate the employment of any employee at any time. No employee or other person shall have any claim or right to receive an Award under the Plan. Receipt of an Award shall not confer upon the Award Recipient any rights of a stockholder with respect to any Shares subject to such Award except as specifically provided in the Agreement relating to the Award.
     D.  Limitation on Dividend Reinvestment and Dividend Equivalents . Reinvestment of dividends in additional Restricted Stock at the time of any dividend payment, and the payment of Shares with respect to dividends to Award Recipients holding Restricted Stock Unit Awards, shall only be permissible if sufficient Shares are available under Section 3 for such reinvestment or payment (taking into account then outstanding Awards). In the event that sufficient Shares are not available for such reinvestment or payment, such reinvestment or payment shall be made in the form of a grant of Restricted Stock Units equal in number to the Shares that would have been obtained by such payment or reinvestment, the terms of which Restricted Stock Units shall provide for settlement in cash and for dividend equivalent reinvestment in further Restricted Stock Units on the terms contemplated by this Section 11(D).
     E.  Subsidiary Employees . In the case of a grant of an Award to any employee of a Subsidiary of the Corporation, the Corporation may, if the Committee so directs, issue or transfer the Shares, if any, covered by the Award to the Subsidiary, for such lawful consideration as the Committee may specify, upon the condition or understanding that the Subsidiary will transfer the Shares to the employee in accordance with the terms of the Award specified by the Committee pursuant to the provisions of the Plan. All Shares underlying Awards that are forfeited or canceled shall revert to the Corporation.
     F.  Governing Law and Interpretation . The Plan and all Awards made and actions taken thereunder shall be governed by and construed in accordance with the laws of the State of Delaware, without reference to principles of conflict of laws. The captions of this Plan are not part of the provisions hereof and shall have no force or effect.
     G.  Foreign Employees and Foreign Law Considerations . The Committee may grant Awards to Eligible Individuals who are foreign nationals, who are located outside the United States or who are not compensated from a payroll maintained in the United States, or who are otherwise subject to (or could cause the Corporation to be subject to) legal or regulatory provisions of countries or jurisdictions outside the United States, on such terms and conditions

16


 

different from those specified in the Plan as may, in the judgment of the Committee, be necessary or desirable to foster and promote achievement of the purposes of the Plan, and, in furtherance of such purposes, the Committee may make such modifications, amendments, procedures, or subplans as may be necessary or advisable to comply with such legal or regulatory provisions.
     H.  Expenses . The expenses of the Plan shall be borne by the Corporation.
     I.  Acceptance of Terms . By accepting an Award under the Plan or payment pursuant to any Award, each Award Recipient, legal representative and Beneficiary shall be conclusively deemed to have indicated his or her acceptance and ratification of, and consent to, any action taken under the Plan by the Committee or the Corporation. A breach by any Award Recipient, his or her Beneficiary(ies), or legal representative, of any restrictions, terms or conditions contained in the Plan, any Award Agreement, or otherwise established by the Committee with respect to any Award will, unless waived in whole or in part by the Committee, cause a forfeiture of such Award.
SECTION 12. Effective Date .
     The Plan was adopted by the Board on March 28, 2006, and it will be effective as of the date (the “ Effective Date ”) it is approved by at least a majority of the Shares of the Corporation present and entitled to vote, at a meeting of the Corporation’s stockholders at which there is a quorum. The Plan will terminate on the tenth (10 th ) anniversary of the Effective Date, unless earlier terminated in accordance with Section 10. Awards outstanding as of the date of termination of the Plan shall not be affected or impaired by the termination of the Plan.

Exhibit 10.11
COMERICA INCORPORATED
RESTRICTED STOCK AWARD AGREEMENT
THIS AGREEMENT (the “Agreement”) between Comerica Incorporated (the “Company”) and [Name] (the “Award Recipient”) is effective as of [Date] (the “Effective Date”). Any undefined terms appearing herein as defined terms shall have the same meaning as they do in the Comerica Incorporated 2006 Long-Term Incentive Plan, as amended and/or restated from time to time (the “Plan”). The Company will provide a copy of the Plan to the Award Recipient upon request.
WITNESSETH:
1.  Award of Stock . Pursuant to the provisions of the Plan, the Company hereby awards the Award Recipient, subject to the terms and conditions of the Plan (incorporated herein by reference), and subject further to the terms and conditions in this Agreement, [# awarded] Shares of $5.00 par value common stock of the Company (the “Stock Award”).
2.  Vesting of Stock Award . The unvested portion of the Stock Award is subject to forfeiture. Subject to the terms of the Plan and this Agreement, including without limitation, fulfillment of the employment requirements in paragraph 4 below, the Stock Award will vest and become free of restrictions in accordance with the following schedule (except in the case of the Award Recipient’s earlier death or Disability or an earlier Change of Control of the Company): 50% of the Shares covered by this Stock Award shall vest and become free of restrictions on the third anniversary of the Effective Date of this Stock Award and 25% of the Shares covered by this Stock Award shall vest and become free of restrictions on each of the fourth and fifth anniversaries of the Effective Date. Any fraction of a Share that becomes exercisable on any date will be rounded down to the next lowest whole number, with any such fraction added to the portion of the Stock Award that vests and becomes free of restrictions on the next vesting date.
As soon as administratively feasible after the vesting of any portion of the Stock Award and the satisfaction of any applicable taxes pursuant to paragraph 12 of this Agreement, the Company will deliver to the Award Recipient (or to the designated Beneficiary of the Award Recipient if the Award Recipient is not then living) evidence of his or her ownership (by book entry or certificate), of the Shares subject to the Stock Award that have vested and for which any applicable taxes have been paid.
3.  Cancellation of Stock Award . The Committee has the right to cancel for no consideration all or any portion of the Stock Award in accordance with Section 4 of the Plan if the Committee determines in good faith that the Award Recipient has done any of the following: (i) committed a felony; (ii) committed fraud; (iii) embezzled; (iv) disclosed confidential information or trade secrets; (v) was terminated for Cause; (vi) engaged in any activity in competition with the business of the Company or any Subsidiary or Affiliate of the Company; or (vii) engaged in conduct that adversely affected the Company. The Delegate shall have the power and authority to suspend the vesting of or the right to receive the Shares in respect of all or any portion of the Stock Award if the Delegate makes in good faith the determination described in the preceding sentence. Any such suspension of a Stock Award shall remain in effect until the suspension shall be presented to and acted on by the Committee at its next meeting. This paragraph 3 shall have no application for the two-year period following a Change of Control of the Company.
4.  Employment Requirements . Except as provided in this Agreement, in order to vest in and not forfeit the Stock Award (or portion thereof, as the case may be), the Award Recipient must remain employed by the Company or one of its Affiliates until the Stock Award (or portion thereof) has vested. If there is a Termination of Employment for any reason (other than due to death or Disability) before a portion of the Stock Award has fully vested, the Award Recipient will forfeit any portion of the Stock Award that has not vested as of the date of the Termination of Employment unless the Committee determines otherwise. If there is a Termination of Employment due to the death or Disability of the Award Recipient prior to this Stock Award fully vesting, the unvested portion of the Stock Award will vest as of the date of the Award Recipient’s Termination of Employment due to death or Disability.
5.  Effect of a Change of Control . This Stock Award will vest and become free of restrictions on the date a Change of Control of the Company occurs.
6.  Nontransferability . No portion of the Shares underlying this Stock Award that have not yet vested, nor any of the rights pertaining thereto or under this Agreement, shall be transferable other than by will or the laws of intestacy until it has vested; provided, however , that the Award Recipient may, in the manner established by the Committee, designate a Beneficiary to receive any property distributable with respect to the Stock Award upon the death of the Award Recipient. The unvested Shares underlying the Stock Award and any rights pertaining thereto or under this Agreement may not be pledged, alienated, attached or otherwise encumbered. Any purported pledge, alienation, attachment or encumbrance of the Stock Award contrary to the provisions of this Agreement or the Plan shall be void and unenforceable against the Company or any Affiliate.
7.  Voting and Dividends . The Award Recipient shall have the right to vote the Shares underlying any portion of the Stock Award that has not vested and to receive any cash dividends or cash distributions that may be paid with respect thereto. Subject

 


 

to Section 11(D) of the Plan, in the event of a stock dividend, stock distribution, stock split, division of shares or other corporate structure change which results in the issuance of additional Shares with respect to any unvested Share of the Stock Award, such additional Shares will be subject to the same restrictions and vesting requirements as are applicable to such unvested Share of the Stock Award.
8.  No Right to Continued Employment. Nothing in the Plan or this Agreement shall confer on the Award Recipient any right to continue in the employment of the Company or its Affiliates for any given period or on any specified terms nor in any way affect the Company’s or its Affiliates’ right to terminate the Award Recipient’s employment without prior notice at any time for any reason or for no reason.
9.  Compliance with Laws and Regulations . The Stock Award and the obligation of the Company to deliver the Shares subject to the Stock Award are subject to compliance with all applicable laws, rules and regulations, to receipt of any approvals by any government or regulatory agency as may be required, and to any determinations the Company may make regarding the application of all such laws, rules and regulations.
10.  Binding Nature of Plan . The Award Recipient agrees to be bound by all terms and provisions of the Plan and related administrative rules and procedures, including terms and provisions and administrative rules and procedures adopted and/or modified after the granting of the Stock Award. In the event any provisions of this Agreement are inconsistent with those of the Plan, the provisions of the Plan shall control.
11.  Notices . Any notice to the Company under this Agreement shall be in writing to the following address or facsimile number: Human Resources — Executive Compensation, Comerica Incorporated, 411 West Lafayette, MC 3122, Detroit, MI 48226; Facsimile Number: 313-964-3153.

Either party may designate in writing some other address or facsimile number for notice under this Agreement.
12.  Withholding . No later than the date as of which an amount first becomes includible in the gross income of the Award Recipient for Federal income tax purposes with respect to any Shares subject to this Stock Award, the Award Recipient shall pay to the Company, or make arrangements satisfactory to the Company regarding the payment of, all Federal, state and local income and employment taxes that are required by applicable laws and regulations to be withheld with respect to such amount. The Award Recipient authorizes the Company to withhold from his or her compensation to satisfy any income and employment tax withholding obligations in connection with the Stock Award. The Award Recipient agrees that the Company may delay removal of the restrictive legend until proper payment of such taxes has been made by the Award Recipient. Unless determined otherwise by the Committee, the Award Recipient may satisfy such obligations under this paragraph 12 by any method authorized under Section 9 of the Plan.
13.  Voluntary Participation. Participation in the Plan is voluntary. The value of the Stock Award is an extraordinary item of compensation outside the scope of the Award Recipient’s employment contract, if any. As such, the Stock Award is not part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments.
14.  Force and Effect . The various provisions of this Agreement are severable in their entirety. Any judicial or legal determination of invalidity or unenforceability of any one provision shall have no effect on the continuing force and effect of the remaining provisions.

Comerica’s claims in the San Francisco Action included misappropriation of trade secrets, breach of contract, intentional interference with employee relationships, breach of fiduciary duty, and unfair competition.

Comerica Bank trade secrets and from engaging in certain solicitation efforts regarding Comerica customers, vendors, and employees.

Wulff of the Offices of Wulff, Quinby & Sochynsky in Oakland, California. At the conclusion of the mediation, certain parties signed an Enforceable Term Sheet to resolve all pending matters between and amongst them. The Enforceable Term Sheet required the parties to prepare and execute this Settlement Agreement and other documents to effectuate the settlement of their disputes.
     J. The Parties desire to settle their disputes on the terms stated herein, without any admission of liability or wrongdoing and in order to avoid the time and expense of continuing to litigate these matters.

Financial Results
 
  •  Reported net income of $893 million, or $5.49 per diluted share for 2006, compared to $861 million, or $5.11 per diluted share, for 2005. Income from continuing operations was $782 million, or $4.81 per diluted share for 2006, compared to $816 million, or $4.84 per diluted share for 2005. The most significant item contributing to the $34 million decrease in income from continuing operations in 2006, when compared to 2005, was an increase in the provision for loan losses of $55 million (after-tax)
 
  •  Returned 17.24 percent on average common shareholders’ equity and 1.58 percent on average assets
 
  •  Generated growth from December 31, 2005 to December 31, 2006 of $4.2 billion in loans and $1.9 billion in unused commitments to extend credit
 
  •  Generated geographic market growth in average loans (excluding Financial Services Division) of eight percent from 2005 to 2006, including Western (15 percent), Texas (19 percent), Florida (25 percent) and Midwest & Other Markets (1 percent)
 
  •  Continued strong credit quality, resulting in a $50 million decline in net loan charge-offs; nonperforming assets increased to $232 million but remained at historically low levels
 
  •  Raised the quarterly cash dividend 7.3 percent, to $0.59 per share, an annual rate of $2.36 per share, for an annual dividend payout ratio of 43 percent, 49 percent excluding the effects of the $108 million after-tax gain on the sale of Munder Capital Management (Munder) discussed below
 
  •  Repurchased 6.6 million shares of outstanding common stock in the open market for $383 million, which combined with dividends, returned 86 percent of earnings to shareholders, 98 percent excluding the effects of the $108 million after-tax gain on the sale of Munder
 
Key Corporate Initiatives
 
  •  Continued organic growth focused in high growth markets, including opening 25 new banking centers in 2006; banking center expansion in 2007 expected to accelerate to about 30 new banking centers
 
  •  Sold Munder and our Mexican bank charter, businesses not central to the Corporation’s strategy
 
  •  Continued to refine and develop the enterprise-wide risk management program, including improvement of analytics, systems, and reporting
 
  •  Managed full-time equivalent staff growth (from continuing operations) to less than one percent, in spite of approximately 145 full-time equivalent employees added to support new banking center openings

OVERVIEW/EARNINGS PERFORMANCE
 
Comerica Incorporated (the Corporation) is a financial holding company headquartered in Detroit, Michigan. The Corporation’s major business segments are the Business Bank, the Retail Bank and Wealth & Institutional Management. The core businesses are tailored to each of the Corporation’s four primary geographic markets: Midwest & Other Markets, Western, Texas and Florida.
 
The accounting and reporting policies of the Corporation and its subsidiaries conform to U.S. generally accepted accounting principles and prevailing practices within the banking industry. The Corporation’s consolidated financial statements are prepared based on the application of accounting policies, the most significant of which are described on page 70 in Note 1 to the consolidated financial statements. The most critical of these significant accounting policies are discussed in the “Critical Accounting Policies” section on page 60 of this financial review.
 
As a financial institution, the Corporation’s principal activity is lending to and accepting deposits from businesses and individuals. The primary source of revenue is net interest income, which is derived principally from the difference between interest earned on loans and interest paid on deposits and other funding sources. The Corporation also provides other products and services that meet the financial needs of customers and which generate noninterest income, the Corporation’s secondary source of revenue. Growth in loans, deposits and noninterest income are affected by many factors, including the economic growth in the markets the Corporation serves, the financial requirements and health of customers, and successfully adding new customers and/or increasing the number of products used by current customers. Success in providing products and services depends on the financial needs of customers and the types of products desired.
 
The Corporation sold its stake in Munder Capital Management (Munder) in 2006 and recognized an after-tax gain of $108 million at closing, reflected in “income from discontinued operations, net of tax” on the consolidated statements of income. This financial review and the consolidated financial statements reflect Munder as a discontinued operation in all periods presented. For detailed information concerning the sale of Munder and the components of discontinued operations, refer to Note 26 to the consolidated financial statements on page 121.
 
The remaining discussion and analysis of the Corporation’s results of operations is based on results from continuing operations.
 
The Corporation generated growth of $4.2 billion in loans and $1.9 billion in unused commitments to extend credit from December 31, 2005 to December 31, 2006. Within average loans, nearly all business lines showed growth in 2006, compared to 2005, including the Corporation’s National Dealer Services (20 percent), Specialty Businesses (20 percent), Commercial Real Estate (16 percent), Small Business (7 percent), and Middle Market (6 percent) loan portfolios. Specialty Businesses includes Entertainment, Energy, the Financial Services Division, Leasing and Technology and Life Sciences. The increase in average loans in the Specialty Businesses loan portfolio was primarily due to increases in average loans in Energy (38 percent), Technology and Life Sciences (31 percent), and the Financial Services Division (25 percent). The Specialty Businesses loan portfolio includes loans in the Corporation’s Financial Services Division, where customers deposit large balances (primarily noninterest-bearing) and the Corporation pays certain customer services expenses (included in noninterest expenses on the consolidated statements of income) and/or makes low-rate loans (included in net interest income on the consolidated statements of income) to such customers. Average loans grew in all primary geographic markets, including Texas (19 percent), Western (17 percent), Florida (25 percent), and Midwest & Other Markets (1 percent) in 2006, compared to 2005. Average deposits increased $1.4 billion, or four percent, in 2006, compared to 2005. The increase in average deposits in 2006, when compared to 2005, was due primarily to a $4.0 billion increase in average institutional certificates of deposit, partially offset by a $2.4 billion decrease in average Financial Services Division deposits, in part due to slower real estate activity in the Western market. Financial Services Division deposit levels may change with the direction of mortgage activity changes, the desirability of such deposits and competition for deposits. Net interest income increased one percent in 2006, compared to 2005, primarily due to loan growth.
 
Noninterest income, excluding net securities gains, net gain (loss) on sales of businesses and income from lawsuit settlement, increased less than one percent in 2006, compared to 2005, resulting primarily from increases in card fees ($7 million) and fiduciary income ($6 million), partially offset by decreases in letter of credit fees ($6 million) and warrant income ($10 million).

The Corporation’s credit staff closely monitors the financial health of lending customers in order to assess ability to repay and to adequately provide for expected losses. Loan quality remained strong during 2006, in spite of the economic and automotive industry problems in Midwest & Other Markets. Credit quality trends resulted in a decline in net credit-related charge-offs in 2006, compared to 2005, and total nonperforming assets remained at historically low levels. The tools developed in the past several years for evaluating the adequacy of the allowance for loan losses, and the resulting information gained from these processes, continue to help the Corporation monitor and manage credit risk.
 
Noninterest expenses increased four percent in 2006, compared to 2005, primarily due to increases in regular salaries ($37 million), share-based compensation ($14 million), interest expense on tax liabilities ($27 million), net occupancy and equipment expense ($9 million), and pension expense ($8 million), partially offset by decreases in customer services expense in the Financial Services Division ($22 million) and credit-related costs ($21 million), which includes the provision for credit losses on lending-related commitments and other real estate expense. Customer services expense represents expenses paid on behalf of Financial Services Division customers, and is one method to attract and retain title and escrow deposits in that division. The $9 million increase in net occupancy and equipment expense in 2006 was primarily due to the addition of 25 new banking centers ($7 million). Full-time equivalent employees from continuing operations increased by less than one percent (approximately 65 employees) from year-end 2005 to year-end 2006, in spite of approximately 145 full-time equivalent employees added to support new banking center openings.
 
A majority of the Corporation’s revenues are generated by the Business Bank business segment, making the Corporation highly sensitive to changes in the business environment in its primary geographic markets. To facilitate better balance among business segments, the Corporation opened 25 new banking centers in 2006 in markets with favorable demographics and plans to continue banking center expansion in these markets. This is expected to provide opportunity for growth across all business segments, especially in the Retail Bank and Wealth & Institutional Management segments, as the Corporation penetrates existing relationships through cross-selling and develops new relationships.
 
For 2007, management expects the following, compared to 2006 (as adjusted for the adoption of FIN 48, explained below):
 
  •  High single-digit average loan growth, excluding Financial Services Division loans, with low single-digit growth in the Midwest market and low double-digit growth in the Western and Texas markets
 
  •  Average earning asset growth slightly less than average loan growth
 
  •  Financial Services Division noninterest-bearing deposits declining about 10 to 15 percent from the fourth quarter 2006 average of $4.0 billion. Financial Services Division loans of $1.9 billion in the fourth quarter 2006 will fluctuate in 2007 with the level of noninterest-bearing deposits
 
  •  Average full year net interest margin of about 3.75 percent
 
  •  Average net credit-related charge-offs of about 20 basis points of average loans, with a provision for credit losses modestly exceeding net charge-offs
 
  •  Low single-digit growth in noninterest income, excluding the Financial Services Division-related lawsuit settlement and the loss on sale of the Mexican bank charter in 2006
 
  •  Low single-digit growth in noninterest expenses, excluding the provision for credit losses on lending-related commitments, basing the increase in noninterest expenses on the table below
 
  •  Effective tax rate of about 32 percent
 
  •  Active capital management within targeted capital ratios (Tier 1 common of 6.50 percent to 7.50 percent and Tier 1 risk-based of 7.25 percent to 8.25 percent)
 
The Corporation will adopt the provisions of Financial Accounting Standards Board Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109” (FIN 48), in the first quarter 2007. FIN 48 permits the Corporation to elect a change in its accounting policy as to where interest on tax liabilities is classified in the consolidated statements of income. Effective January 1, 2007, the Corporation will change its accounting policy and classify interest on tax liabilities in the “provision for income taxes” on the

consolidated statements of income and will reclassify all prior periods presented. Upon adoption, the Corporation will reclassify $38 million and $11 million of interest on tax liabilities related to 2006 and 2005, respectively, from “other noninterest expenses” to the “provision for income taxes” on the consolidated statements of income. The Corporation’s summarized statements of income from continuing operations for 2006 and 2005 will be as follows:

Net Interest Income
 
Net interest income is the difference between interest and yield-related fees earned on assets and interest paid on liabilities. Adjustments are made to the yields on tax-exempt assets in order to present tax-exempt income and fully taxable income on a comparable basis. Gains and losses related to the effective portion of risk management interest rate swaps that qualify as hedges are included with the interest income or expense of the hedged item when classified in net income. Net interest income on a fully taxable equivalent (FTE) basis comprised 70 percent of net revenues in 2006, compared to 71 percent in 2005 and 69 percent in 2004. Table 2 on page 24 of this


25


Table of Contents

financial review provides an analysis of net interest income for the years ended December 31, 2006, 2005 and 2004. The rate-volume analysis in Table 3 above details the components of the change in net interest income on a FTE basis for the years ended December 31, 2006, compared to 2005 and December 31, 2005, compared to 2004.
 
Net interest income (FTE) was $2.0 billion in 2006, an increase of $26 million, or one percent, from 2005. The net interest margin (FTE), which is net interest income (FTE) expressed as a percentage of average earning assets, decreased to 3.79 percent in 2006, from 4.06 percent in 2005. The increase in net interest income in 2006 was due to strong loan growth, which was nearly offset by a decline in noninterest-bearing deposits (primarily in the Financial Services Division), competitive environments for both loan and deposit pricing and the impact of a warrant accounting change discussed in Note 1 to the consolidated financial statements on page 70, which increased net interest income by $20 million in 2005. A greater contribution from noninterest-bearing deposits in a higher rate environment also benefited net interest income in 2006. The decrease in net interest margin (FTE) was due to the 2005 warrant accounting change, which increased the 2005 net interest margin by four basis points, the changes in average Financial Services Division loans and noninterest-bearing deposits discussed below, competitive loan and deposit pricing, a change in the interest-bearing deposit mix toward higher-cost deposits and the margin impact of loan growth funded with non-core deposits and purchased funds. These decreases in the net interest margin (FTE) were partially offset by a greater contribution from noninterest-bearing deposits in a higher rate environment. Average earning assets increased $4.1 billion, or eight percent, to $52.3 billion in 2006, compared to 2005, primarily as a result of a $3.9 billion increase in average loans and a $131 million increase in average investment securities available-for-sale. Average Financial Services Division loans (primarily low-rate) increased $470 million, and average Financial Services Division noninterest-bearing deposits decreased $1.5 billion in 2006, compared to 2005.
 
The Corporation expects, on average, net interest margin in 2007 to be about 3.75 percent for the full year.
 
Net interest income and net interest margin are impacted by the operations of the Corporation’s Financial Services Division. Financial Services Division customers deposit large balances (primarily noninterest-bearing) and the Corporation pays certain customer services expenses (included in “noninterest expenses” on the consolidated statements of income) and/or makes low-rate loans (included in “net interest income” on the consolidated statements of income) to such customers. Footnote (1) to Table 2 on page 24 of this financial review displays average Financial Services Division loans and deposits, with related interest income/expense and average rates. As shown in Footnote (2) to Table 2 on page 24 of this financial review, the impact of Financial Services Division loans (primarily low-rate) on net interest margin (assuming the loans were funded by Financial Services Division noninterest-bearing deposits) was a decrease of 16 basis points and 15 basis points in 2006 and 2005, respectively.
 
The Corporation implements various asset and liability management tactics to manage net interest income exposure to interest rate risk. This risk represents the potential reduction in net interest income that may result from a fluctuating economic environment, including changes to interest rates and loan and deposit portfolio growth rates. Such actions include the management of earning assets, funding and capital and the use of interest rate swap contracts. Interest rate swap contracts are employed to effectively fix the yields on certain variable rate loans and to alter the interest rate characteristics of deposits and debt issued throughout the year. Refer to the “Interest Rate Risk” section on page 53 of this financial review for additional information regarding the Corporation’s asset and liability management policies.
 
In 2005, net interest income (FTE) was $2.0 billion, an increase of $146 million, or eight percent, from 2004. The net interest margin (FTE) increased to 4.06 percent in 2005, from 3.86 percent in 2004. The increases in net interest income and net interest margin resulted primarily from a greater contribution from noninterest-bearing deposits in a higher rate environment and loan growth. Net interest income in 2005 was also impacted by the warrant accounting change, discussed in Note 1 to the consolidated financial statements on page 70, which resulted in a $20 million increase in net interest income and a four basis point increase in the net interest margin in 2005. Average earning assets increased $1.3 billion, or three percent, to $48.2 billion in 2005, compared to 2004, primarily as a result of a $3.1 billion increase in average loans, partially offset by a $1.3 billion decline in average federal funds sold and securities purchased under agreements to resell, and a $460 million decline in average investment securities available-for-sale.

Provision for Credit Losses
 
The provision for credit losses includes both the provision for loan losses and the provision for credit losses on lending-related commitments. The provision for loan losses reflects management’s evaluation of the adequacy of the allowance for loan losses. The allowance for loan losses represents management’s assessment of probable losses inherent in the Corporation’s loan portfolio. The provision for credit losses on lending-related commitments, a component of “noninterest expenses” on the consolidated statements of income, reflects management’s assessment of the adequacy of the allowance for credit losses on lending-related commitments. The allowance for credit losses on lending-related commitments, which is included in “accrued expenses and other liabilities” on the consolidated balance sheets, covers probable credit-related losses inherent in credit-related commitments, including letters of credit and financial guarantees. The Corporation performs a quarterly credit quality review to determine the adequacy of both allowances. For a further discussion of the both the allowance for loan losses and the allowance for credit losses on lending-related commitments, refer to the “Credit Risk” section of this financial review on page 44, and the “Critical Accounting Policies” section on page 60 of this financial review.
 
The provision for loan losses was $37 million in 2006, compared to a negative provision of $47 million in 2005 and a provision of $64 million in 2004. The $84 million increase in the provision for loan losses in 2006, compared to 2005, resulted primarily from loan growth, challenges in the automotive industry and the Michigan commercial real estate industry and a leveling off of credit quality improvement trends. These credit trends reflect economic conditions in the Corporation’s primary geographic markets. While the economic conditions in the Corporation’s Michigan market deteriorated over the last year, the economic conditions in the Texas market have continued to improve somewhat faster than growth in the national economy, while California appears to be improving, but at a rate equal to or slightly slower than the nation as a whole. The average 2006 Michigan Business Activity index compiled by the Corporation declined approximately three percent when compared to the average for 2005. Intense restructuring efforts in the Michigan-based automotive sector are creating a significant drag on the state economy. Forward-looking indicators suggest that current economic conditions in the Corporation’s primary markets are likely to continue in 2007. The decrease in the provision for loan losses in 2005, when compared to 2004, was primarily the result of improving credit quality trends in net loan charge-offs and watch list loans (generally consistent with regulatory defined special mention, substandard and doubtful credits).
 
The provision for credit losses on lending-related commitments was $5 million in 2006, compared to a provision of $18 million in 2005 and a negative provision of $12 million in 2004. The decrease in the provision for credit losses on lending-related commitments in 2006 was primarily due to reduced reserve needs resulting from improved market values for unfunded commitments to certain customers in the automotive industry. The increase in 2005 resulted primarily from increases in specific reserves related to unused commitments to extend credit to customers in the automotive industry. An analysis of the changes in the allowance for credit losses on lending-related commitments is presented on page 45 of this financial review.
 
Net loan charge-offs in 2006 were $60 million, or 0.13 percent of average total loans, compared to $110 million, or 0.25 percent, in 2005 and $194 million, or 0.48 percent, in 2004. Total net credit-related charge-offs, which includes charge-offs on both loans and lending-related commitments, were $72 million, or 0.15 percent of average total loans, in 2006, compared to $116 million, or 0.26 percent, in 2005 and $194 million, or 0.48 percent, in 2004. Of the $44 million decrease in net credit-related charge-offs in 2006, compared to 2005, net credit-related charge-offs in the Business Bank business segment decreased $49 million, partially offset by an increase of $10 million in the Retail Bank business segment. Net credit-related charge-offs in the Midwest & Other Markets and Western geographic markets decreased $30 million and $11 million, respectively, in 2006, compared to 2005. Net credit-related charge-offs in 2006 were impacted by a decision to sell a $74 million portfolio of loans related to manufactured housing. These loans were transferred to held-for-sale in the fourth quarter 2006, which required a charge-off of $9 million to adjust the loans to estimated fair value. An analysis of the changes in the allowance for loan losses, including charge-offs and recoveries by loan category, is presented in Table 8 on page 45 of this financial review. An analysis of the changes in the allowance for credit losses on lending-related commitments is presented on page 45 of this financial review.
 
Management expects full-year 2007 average net credit-related charge-offs of about 20 basis points of full-year 2007 average loans, with a provision for credit losses modestly exceeding net charge-offs.

Noninterest income increased $36 million, or five percent, to $855 million in 2006, compared to $819 million in 2005, and increased $11 million, or one percent, in 2005, compared to $808 million in 2004. Excluding net gain (loss) on sales of businesses ($(12) million, $1 million and $7 million in 2006, 2005 and 2004, respectively), and income from lawsuit settlement ($47 million in 2006), noninterest income increased less than one percent in 2006 and two percent in 2005. An analysis of increases and decreases by individual line item is presented below.
 
Service charges on deposit accounts remained flat at $218 million in 2006, compared to a decrease of $13 million, or six percent, in 2005. In 2006, additional non-check volumes from new and existing treasury management customers and an increase in web-based payment product revenues were offset by the impact of higher earnings credit allowances provided to business customers. The decrease in 2005 was primarily due to higher earnings credit allowances provided to business customers, driven by a higher interest rate environment, and the popularity of free checking accounts which were marketed beginning in mid-2004.
 
Fiduciary income increased $6 million, or four percent, in 2006 and increased $8 million, or four percent, in 2005. Personal and institutional trust fees are the two major components of fiduciary income. These fees are based on services provided and assets managed. Fluctuations in the market values of the underlying assets managed, which include both equity and fixed income securities, impact fiduciary income. The increase in 2006 was from a combination of net new business and market appreciation. The increase in 2005 was primarily due to improvements in equity markets during that year.
 
Commercial lending fees increased $2 million, or two percent, in 2006, compared to an increase of $8 million, or 16 percent, in 2005. The increase in 2006 was primarily due to continued strength in the syndicated lending market and higher commercial loan commitment fees paid in arrears. The increase in 2005 was primarily due to an increase in fees resulting from increased opportunities in 2005 to lead or co-lead syndicated lending arrangements.
 
Letter of credit fees decreased $6 million, or eight percent, in 2006, compared to an increase of $4 million, or six percent, in 2005. Of the decline, $3 million reflected the impact, in 2005, of an adjustment of deferred fee amortization to more closely align the amortization periods with actual terms of the letters of credit. The 2005 increase in letter of credit fees was principally due to the 2005 adjustment of deferred fee amortization described above.
 
Foreign exchange income remained relatively flat at $38 million in 2006, compared to $37 million in both 2005 and 2004.
 
Brokerage fees of $40 million increased $4 million, or 10 percent, in 2006, compared to $36 million in both 2005 and 2004. Brokerage fees include commissions from retail broker transactions and mutual fund sales and are subject to changes in the level of market activity. The increase in 2006 was primarily due to increased transaction volumes as a result of improved market conditions.

Card fees, which consist primarily of interchange fees earned on debit and commercial cards, increased $7 million, or 17 percent, to $46 million, compared to $39 million in 2005, and increased $7 million, or 22 percent, compared to $32 million in 2004. Growth in both 2006 and 2005 resulted primarily from an increase in transaction volume caused by the continued shift to electronic banking and new customer accounts.
 
Bank-owned life insurance income increased $2 million, to $40 million in 2006, compared to an increase of $4 million, to $38 million in 2005. The increases in both 2006 and 2005 resulted primarily from increased earnings and death benefits received on policies held.
 
Warrant income (loss) was $(1) million in 2006, compared to $9 million in 2005 and $7 million in 2004. In 2005, the Corporation changed its accounting for warrants to recognize in warrant income the changes in the fair value of warrants held. For a further discussion of warrant accounting, refer to Note 1 to the consolidated financial statements on page 70.
 
The net gain (loss) on sales of businesses in 2006 included a net loss of $12 million on the sale of the Corporation’s Mexican bank charter, while 2004 included a net gain of $7 million on the sale of a portion of the Corporation’s merchant card processing business.
 
The income from lawsuit settlement of $47 million in 2006 resulted from a payment received to settle a Financial Services Division-related lawsuit in the fourth quarter 2006.
 
Other noninterest income decreased $4 million, or three percent, in 2006, compared to a decrease of $3 million, or two percent, in 2005. The following table illustrates fluctuations in certain categories included in “other noninterest income” on the consolidated statements of income.

Noninterest expenses increased $61 million, or four percent, to $1,674 million in 2006, compared to $1,613 million in 2005, and increased $155 million, or 11 percent, in 2005, compared to $1,458 million in 2004. Increases in regular salaries ($37 million), share-based compensation ($14 million), interest expense on tax liabilities ($27 million), net occupancy and equipment expense ($9 million), and pension expense ($8 million) accounted for a majority of the increase, partially offset by a decrease in customer services expense in the Financial Services Division ($22 million) and credit-related costs ($21 million), including the provision for credit losses on lending-related commitments and other real estate expense. An analysis of increases and decreases by individual line item is presented below.
 
The following table summarizes the various components of salaries and employee benefits expense.

Salaries expense increased $37 million, or five percent, in 2006, compared to an increase of $50 million, or seven percent, in 2005. The increase in 2006 was primarily due to increases in regular salaries of $37 million and share-based compensation of $14 million. The increase in regular salaries in 2006 was primarily the result of annual merit increases of approximately $17 million and increased contract labor costs associated with technology-related projects, including a large project to standardize the Corporation’s workstation operating system and office automation suite. In addition, staff size from continuing operations increased approximately 65 full-time equivalent employees from year-end 2005 to year-end 2006, in spite of approximately 145 full-time equivalent employees added to support new banking center openings. Share-based compensation expense increased primarily as a result of adopting the requisite service period provisions of SFAS No. 123 (revised 2004) (SFAS 123(R)), “Shared-Based Payment,” effective January 1, 2006, as discussed in Notes 1 and 15 to the consolidated financial statements on pages 70 and 92, respectively. These increases were partially offset by a $16 million decline in business unit and executive incentives, which included a $6 million decline in warrant-related incentives. Business unit incentives are tied to new business and business unit profitability, while executive incentives are tied to peer-based comparisons of corporate results. The increase in salaries expense in 2005 was primarily due to a $32 million increase in business unit and executive incentives, including an accrual of $4 million related to the warrant accounting change discussed in Note 1 to the consolidated financial statements on page 70, annual merit increases of approximately $17 million and an increase of $9 million in share-based compensation expense. These increases were partially offset by a full-time equivalent employee reduction in staff size from continuing operations of approximately 85 employees from year-end 2004 to year-end 2005 and a $3 million decline in severance expense.
 
Employee benefits expense increased $6 million, or three percent, in 2006, compared to an increase of $24 million, or 16 percent, in 2005. The increases in 2006 and 2005 resulted primarily from increases in pension expense. For a further discussion of pension expense, refer to the “Critical Accounting Policies” on page 60 of this financial review and Note 16 to the consolidated financial statements on page 94.
 
Net occupancy and equipment expense, on a combined basis, increased $9 million, or six percent, to $180 million in 2006, compared to a decrease of $5 million, or three percent, in 2005. Net occupancy and equipment expense increased $7 million due to the addition of 25 new banking centers in 2006, and 18 in 2005,

mitigated in part by savings of approximately $2 million due to the purchase of a previously leased operations center in March 2005. The decrease in net occupancy expense in 2005 occurred in spite of the addition of new banking centers in 2005, due to savings of approximately $5 million realized from the aforementioned operations center purchase and other lease re-negotiations.
 
Outside processing fee expense increased $8 million, or 10 percent, to $85 million in 2006, from $77 million in 2005, compared to an increase of $10 million, or 15 percent, in 2005. The 2006 increase in outside processing fees resulted primarily from the outsourcing of certain trust and retirement services processing and a new electronic bill payment service marketed to corporate customers in 2006. The 2005 increase in outside processing fees resulted, in part, from the outsourcing of certain retirement services processing beginning in the second quarter of 2005.
 
Software expense increased $7 million, or 15 percent, in 2006, compared to an increase of $6 million, or 13 percent in 2005. The increases in both 2006 and 2005 were primarily due to increased investments in technology and the implementation of several systems, including tools for the enterprise-wide risk management program, an image check settlement system and a sales tracking system in the banking centers, increasing both amortization and maintenance costs.
 
Customer services expense decreased $22 million, or 33 percent, to $47 million in 2006, from $69 million in 2005, and increased $46 million, or 203 percent, in 2005, compared to $23 million in 2004. Customer services expense represents compensation provided to customers, and is one method to attract and retain title and escrow deposits in the Financial Services Division. The amount of customer services expense varies from period to period as a result of changes in the level of noninterest-bearing deposits and low-rate loans in the Financial Services Division and the earnings credit allowances provided on these deposits, as well as a competitive environment.
 
Litigation and operational losses decreased $3 million, or 17 percent, to $11 million in 2006, from $14 million in 2005, and decreased $10 million, or 43 percent, in 2005, compared to $24 million in 2004. Litigation and operational losses include traditionally defined operating losses, such as fraud or processing problems, as well as uninsured losses and litigation losses. These expenses are subject to fluctuation due to timing of authorized and actual litigation settlements as well as insurance settlements.
 
The provision for credit losses on lending-related commitments was $5 million in 2006, compared to $18 million in 2005 and a negative provision of $12 million in 2004. For additional information on the provision for credit losses on lending-related commitments, refer to Notes 1 and 20 to the consolidated financial statements on pages 70 and 102, respectively, and the “Provision for Credit Losses” section on page 27 of this financial review.
 
Other noninterest expenses increased $32 million, or 13 percent, in 2006, compared to a $4 million, or two percent, increase in 2005. The following table illustrates the fluctuations in certain categories included in “other noninterest expenses” on the consolidated statements of income. For a further discussion of interest on tax liabilities, refer to “Income Taxes and Tax-Related Items” below.

Management expects low single-digit growth in noninterest expenses in 2007 compared to 2006 levels, excluding the provision for credit losses on lending-related commitments, basing the increase on noninterest expenses as adjusted for the adoption of FIN 48 in the table on page 23 of this financial review.
 
The Corporation’s efficiency ratio is defined as total noninterest expenses divided by the sum of net interest income (FTE) and noninterest income, excluding net securities gains. The ratio increased to 58.92 percent in 2006, compared to 58.01 percent in 2005 and 55.60 percent in 2004. The efficiency ratio increased in 2006 and 2005 primarily due to higher expense levels.

Income Taxes and Tax-Related Items
 
The provision for income taxes was $345 million in 2006, compared to $393 million in 2005 and $349 million in 2004. In the first quarter 2006, the IRS completed the examination of the Corporation’s federal tax returns for the years 1996 through 2000. Tax reserves, which includes the provision for income taxes and interest on tax liabilities (included in “other noninterest expenses”) were adjusted to reflect the resolution of those tax years, and to reflect an updated assessment of reserves on certain types of structured lease transactions and a series of loans to foreign borrowers. Tax-related interest expense was also reduced by $6 million in the second quarter 2006, upon settlement of various refund claims with the IRS. As previously disclosed in quarterly and annual SEC filings under the heading “Tax Contingency,” the examination staff with the Internal Revenue Service (IRS) disallowed the benefits related to a series of loans to foreign borrowers. The Corporation has had ongoing discussions with the IRS related to the disallowance. In the fourth quarter 2006, based on settlements discussed, the Corporation recorded a charge to its tax reserves for the disallowed loan benefits. The following table summarizes the impact of the items described above on the Corporation’s consolidated statement of income for the year ended December 31, 2006.

The effective tax rate, computed by dividing the provision for income taxes by income before income taxes, was 30.6 percent in 2006, 32.5 percent in 2005 and 31.8 percent in 2004. Changes in the effective tax rate in 2006 from 2005, and 2005 from 2004, are shown in Note 17 to the consolidated financial statements on page 99. The Corporation had a net deferred tax liability of $111 million at December 31, 2006. Included in net deferred taxes were deferred tax assets of $558 million, which the Corporation’s management believes will be realized in future periods. In the event that the future taxable income does not occur in the manner anticipated, other initiatives could be undertaken to preclude the need to recognize a valuation allowance against the deferred tax asset.
 
Management expects an effective tax rate for the full-year 2007 of about 32 percent.
 
Income from Discontinued Operations, Net of Tax
 
Income from discontinued operations, net of tax, was $111 million in 2006, compared to $45 million in 2005 and $9 million in 2004. The increase in 2006, compared to 2005, was primarily due to the $108 million after-tax gain on the sale of the Corporation’s Munder subsidiary in the fourth quarter 2006, partially offset by an $8 million after-tax transition adjustment expense related to SFAS No. 123(R) recorded in the first quarter 2006 and the $32 million after-tax gain in the fourth quarter 2005 that resulted from Munder’s sale of its minority interest in Framlington Group Limited (Framlington) (a London, England based investment manager). The increase in 2005, when compared to 2004, primarily resulted from Munder’s 2005 gain on the sale of Framlington discussed above. For further information on discontinued operations, refer to Note 26 to the consolidated financial statements on page 121.

STRATEGIC LINES OF BUSINESS
 
Business Segments
 
The Corporation’s operations are strategically aligned into three major business segments: the Business Bank, the Retail Bank and Wealth & Institutional Management. These business segments are differentiated based upon the products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. The Other category includes discontinued operations and items not directly associated with these business segments or the Finance Division. Note 24 to the consolidated financial statements on page 114 describes the business activities of each business segment and the methodologies which form the basis for these results, and presents financial results of these business segments for the years ended December 31, 2006, 2005 and 2004.

Net interest income (FTE) of $1.3 billion in 2006, decreased $80 million, or six percent, compared to 2005, due to a decline in loan spreads, an increase in low-yield Financial Services Division loans, a decline in Financial Services Division noninterest-bearing deposits, and a $20 million adjustment related to a change in warrant accounting policy recognized in third quarter 2005, partially offset by a $3.1 billion, or nine percent, increase in average loan balances (excluding Financial Services Division). The provision for loan losses increased $86 million in 2006, primarily due to loan growth, challenges in the automotive industry and the Michigan commercial real estate industry and a leveling off of credit quality improvement trends in 2006, compared to improving credit quality trends in 2005, as discussed in the “Provision for Credit Losses” section of this financial review on page 27. Noninterest income of $305 million in 2006, increased $22 million from 2005, reflecting a $47 million payment received to settle a Financial Services Division-related lawsuit, partially offset by a $12 million loss on the sale of the Corporation’s Mexican bank charter in 2006. In addition, warrant income decreased $10 million and investment banking fees increased $4 million in 2006, when compared to 2005. Noninterest expenses of $715 million, increased $4 million in 2006, primarily due to a $24 million increase in allocated net corporate overhead expenses, a $6 million increase in outside processing fee expense, a $5 million increase in legal fees, partially offset by a $22 million decrease in customer services expense and an $11 million decrease in the provision for credit losses on lending-related commitments. The corporate overhead allocation rates used were 14 percent and 10 percent in 2006 and 2005, respectively. The four percentage point increase in rate in 2006, when compared to 2005, resulted mostly from income tax related items.
 
The Retail Bank’s net income decreased $34 million, or 21 percent, to $134 million in 2006, compared to an increase of $3 million, or two percent, to $168 million in 2005. Net interest income (FTE) of $635 million, increased $27 million, or four percent, in 2006, primarily due to an improvement in deposit spreads. The provision for loan losses increased $21 million in 2006, primarily due to stable credit quality trends in 2006, compared to improving credit quality trends in 2005. Noninterest income was relatively flat at $209 million in

2006, compared to $208 million in 2005. Noninterest expenses of $619 million increased $67 million in 2006, primarily due to a $24 million increase in allocated net corporate overhead expenses, a $14 million increase in salaries and employee benefits expense, and a $6 million increase in net occupancy expense related to new banking centers. Refer to the Business Bank discussion above for an explanation on the increase in allocated net corporate overhead expenses. The Corporation opened 25 new banking centers in 2006 and 18 new banking centers in 2005, contributing $30 million to noninterest expenses in 2006, an increase of $15 million compared to 2005. In addition, the Corporation consolidated 11 banking centers in Michigan in 2006 which resulted in approximately $6 million in expense savings in 2006. Net credit-related charge-offs were impacted by a decision to sell a $74 million portfolio of loans related to manufactured housing. These loans were transferred to held-for-sale in the fourth quarter 2006, which required a charge-off of $9 million to adjust the loans to estimated fair value.
 
Wealth & Institutional Management’s net income decreased $3 million, or five percent, to $56 million in 2006, compared to a decrease of $8 million, or 11 percent, to $59 million in 2005. Net interest income (FTE) of $149 million decreased $1 million, or less than one percent, in 2006, compared to 2005, primarily due to declines in loan and deposit spreads, partially offset by an increase in average loan balances. The provision for loan losses increased $4 million, primarily due to stable credit quality trends in 2006, compared to improving credit quality trends in 2005. Noninterest income of $259 million increased $5 million, or two percent, in 2006, primarily due to a $6 million increase in trust fees. Noninterest expenses of $325 million increased $10 million, or three percent, in 2006, primarily due to a $9 million increase in allocated net corporate overhead expenses and a $5 million increase in outside processing fee expense, partially offset by an $8 million decrease in other real estate expense. Refer to the Business Bank discussion above for an explanation on the increase in allocated net corporate overhead expenses.
 
The net loss in the Finance Division was $20 million in 2006, compared to a net loss of $72 million in 2005. Contributing to the decrease in net loss was an $82 million increase in net interest income (FTE), primarily due to the rising rate environment in which interest income received from the lending-related business units rises more quickly than the longer-term value attributed to deposits generated by the business units. In addition, noninterest expenses increased $5 million in 2006, compared to 2005, in part due to accrued expenses related to a 2006 irrevocable commitment to redeem trust preferred securities in 2007.
 
Net income in the Other category was $137 million for 2006, compared to $35 million for 2005. Contributing to the increase in net income was a $27 million decrease in the unallocated provision for loan losses, resulting from reduced new business migration risk reserves based on improved data, as well as improved risk rating accuracy in the Corporation’s commercial loan portfolio. Noninterest income increased $8 million, due in part to a $3 million increase in income from indirect private equity and venture capital investments. Income from discontinued operations, net of tax, increased $66 million, primarily due to the $108 million after-tax gain on the sale of the Corporation’s Munder subsidiary in 2006, compared to the $32 million after-tax gain that resulted from Munder’s sale of its minority interest in Framlington in 2005.

Total loans were $47.4 billion at December 31, 2006, an increase of $4.2 billion from $43.2 billion at December 31, 2005. Total loans, on an average basis, increased $3.9 billion, or nine percent, ($3.5 billion, or eight percent, excluding Financial Services Division loans), to $47.8 billion in 2006, from $43.8 billion in 2005. Within average loans, nearly all business lines and all geographic markets showed growth. The Corporation continues to make progress toward the goal of achieving more geographic balance with the Western, Texas, and Florida markets comprising 47 percent of average total loans (excluding Financial Services Division loans) in 2006, compared to 44 percent in 2005.
 
Average commercial real estate loans, consisting of real estate construction and commercial mortgage loans, increased $1.4 billion, or 12 percent, to $13.2 billion in 2006, from $11.8 billion in 2005. Commercial mortgage loans are loans where the primary collateral is a lien on any real property. Real property is generally considered primary collateral if the value of that collateral represents more than 50 percent of the commitment at loan approval. Average loans to borrowers in the Commercial Real Estate business line represented $4.7 billion, or 36 percent, of the 2006 $13.2 billion average commercial real estate loans, compared to $4.1 billion, or 35 percent, of the 2005 $11.8 billion average commercial real estate loans. The remaining $8.5 billion and $7.7 billion of commercial real estate loans in 2006 and 2005, respectively, were primarily owner-occupied commercial mortgages. In addition to the $4.7 billion of average 2006 commercial real estate loans discussed above, the Commercial Real Estate business line also had $1.7 billion of average 2006 loans not classified as commercial real estate on the consolidated balance sheet.
 
Average residential mortgage loans increased $182 million, or 13 percent, from 2005, due to management’s decision to retain mortgages originated for certain relationship customers.

Average home equity loans decreased $110 million, or six percent, from 2005, as a result of market conditions, particularly in Michigan.
 
Shared National Credit Program (SNC) loans totaled $8.8 billion (approximately 1,000 borrowers) at December 31, 2006, compared to $6.6 billion (approximately 870 borrowers) at December 31, 2005. SNC loans are facilities greater than $20 million shared by three or more federally supervised financial institutions which are reviewed by regulatory authorities at the agent bank level. These loans, diversified by both line of business and geography, comprised approximately 19 percent and 15 percent of total loans at December 31, 2006 and 2005, respectively.
 
Management currently expects average loan growth for 2007 to be in the high single-digit range, excluding Financial Services Division loans, with low single-digit growth in the Midwest market and low double-digit growth in the Western and Texas markets, compared to 2006.

Investment securities available-for-sale decreased $578 million to $3.7 billion at December 31, 2006, from $4.2 billion at December 31, 2005. Average investment securities available-for-sale increased $131 million to $4.0 billion in 2006, compared to $3.9 billion in 2005, primarily due to a $171 million increase in average U.S. Treasury, Government agency, and Government-sponsored enterprise securities. Changes in U.S. Treasury, Government agency, and Government-sponsored enterprise securities resulted from interest rate risk and balance sheet management decisions. Average other securities decreased $38 million to $146 million in 2006, and consisted largely of money market and other fund investments at December 31, 2006.
 
Short-term investments include federal funds sold and securities purchased under agreements to resell, and other short-term investments. Federal funds sold offer supplemental earning opportunities and serve

correspondent banks. Average federal funds sold and securities purchased under agreements to resell declined $107 million to $283 million during 2006, compared to 2005. Other short-term investments include interest-bearing deposits with banks, trading securities, and loans held-for-sale. Interest-bearing deposits with banks are investments with banks in developed countries or foreign banks’ international banking facilities located in the United States. Loans held-for-sale typically represent residential mortgage loans and Small Business Administration loans that have been originated and which management has decided to sell. Average other short-term investments increased $101 million to $266 million during 2006, compared to 2005. Short-term investments, other than loans held-for-sale, provide a range of maturities less than one year and are mostly used to manage short-term investment requirements of the Corporation.

Risk management practices minimize risk inherent in international lending arrangements. These practices include structuring bilateral agreements or participating in bank facilities, which secure repayment from sources external to the borrower’s country. Accordingly, such international outstandings are excluded from the cross-border risk of that country. Mexico, with cross-border outstandings of $922 million, or 1.59 percent of total assets at December 31, 2006, and Canada, with cross-border outstandings of $721 million, or 1.24 percent of total assets at December 31, 2006, were the only countries with outstandings exceeding 1.00 percent of total assets at year-end 2006. The Netherlands, with cross-border outstandings of $439 million, or 0.76 percent of total assets at December 31, 2006, was the only country with cross-border outstandings between 0.75 and 1.00 percent of total assets at year-end 2006. Additional information on the Corporation’s international cross-border risk in countries where the Corporation’s outstandings exceeded 1.00 percent of total assets at the end of one or more of the three years in the period ended December 31, 2006 is provided in Table 7 above.

Average deposits were $42.1 billion during 2006, an increase of $1.4 billion, or four percent, from 2005. The $3.3 billion, or 13 percent, increase in average interest-bearing deposits in 2006, when compared to 2005, resulted primarily from an increase in average customer and institutional certificates of deposit. Institutional certificates of deposit represent certificates of deposit issued to institutional investors in denominations in excess of $100,000 and are an alternative to other sources of purchased funds. The increases in certificates of deposit were partially offset by decreases in average money market, NOW and savings deposits. Average noninterest-bearing deposits decreased $1.9 billion, or 12 percent, from 2005. Noninterest-bearing deposits include title and escrow deposits in the Corporation’s Financial Services Division, which benefit from home mortgage financing and refinancing activity. Deposit levels may change with the direction of mortgage activity changes, and the desirability of and competition for such deposits. Average Financial Services Division noninterest-bearing deposits decreased $1.5 billion, to $4.4 billion in 2006, from $5.9 billion in 2005.
 
Average short-term borrowings increased $1.2 billion, to $2.7 billion in 2006, compared to $1.5 billion in 2005. Short-term borrowings include federal funds purchased, securities sold under agreements to repurchase, commercial paper and treasury tax and loan notes.
 
The Corporation uses medium-term debt (both domestic and European) and long-term debt to provide funding to support earning assets while providing liquidity that mirrors the estimated duration of deposits. Long-term subordinated notes further help maintain the Corporation’s and subsidiary banks’ total capital ratios at a level that qualifies for the lowest FDIC risk-based insurance premium. Medium- and long-term debt increased, on an average basis, by $1.2 billion. Further information on medium- and long-term debt is provided in Note 11 to the consolidated financial statements on page 86.

Capital
 
Common shareholders’ equity was $5.2 billion at December 31, 2006, compared to $5.1 billion at December 31, 2005. The following table presents a summary of changes in common shareholders’ equity in 2006:

Balance at December 31, 2006
  $ 5,153  
         
 
 
Includes a $(209) million after-tax transition adjustment to apply the provisions of SFAS 158, partially offset by an increase in accumulated net gains on cash flow hedges ($43 million).
 
 
Further information on the change in accumulated other comprehensive income (loss) is provided in Note 13 to the consolidated financial statements on page 89.
 
The Corporation declared common dividends totaling $380 million, or $2.36 per share, on net income applicable to common stock of $893 million. The dividend payout ratio calculated on a per share basis, was 43 percent in 2006 and 2005, and 48 percent in 2004.
 
The Corporation recognizes the need to limit capital in order to ensure returns that are consistent with shareholder expectations. The Corporation assesses capital adequacy against the risk inherent in the balance sheet, recognizing that unexpected loss is the common denominator of risk, and that common equity has the greatest capacity to absorb unexpected loss. Appropriate capitalization is therefore defined through the use of a target capital range. The Corporation targets to maintain a Tier 1 common capital ratio of between 6.5% and 7.5% and a Tier 1 risk-based capital ratio of between 7.25% and 8.25%. The Tier 1 common capital ratio is defined as the ratio of common equity to risk-adjusted assets. Common shareholders’ equity was reduced on December 31, 2006 by a $209 million after-tax charge associated with a new accounting standard (SFAS 158) on pension and postretirement plan accounting. Based on the interim decision issued by the banking regulators, this charge was excluded from the calculation of regulatory capital ratios. Refer to note 19 on page 101 for further discussion of regulatory capital requirements and capital ratio calculations.
 
When capital exceeds necessary levels, the Corporation’s common stock can be repurchased as a way to return excess capital to shareholders. Repurchasing common stock offers a flexible way to control capital levels by adjusting the capital deployed in reaction to core balance sheet growth. In July 2005, and again in November 2006, the Board of Directors of the Corporation (the Board) authorized the purchase of up to 10 million shares of Comerica Incorporated outstanding common stock in the open market. In addition to limits that result from the Board authorization, the share repurchase program is constrained by holding company liquidity and capital levels relative to internal targets and regulatory minimums. The Corporation repurchased 6.6 million shares in the open market in 2006 for $383 million, compared to 9.0 million shares in 2005 for $525 million. Comerica Incorporated common stock available for repurchase under Board authority totaled 12.6 million shares at December 31, 2006. Refer to Note 12 to the consolidated financial statements on page 88 for additional information on the Corporation’s share repurchase program.
 
At December 31, 2006, the Corporation and its U.S. banking subsidiaries exceeded the capital ratios required for an institution to be considered “well capitalized” by the standards developed under the Federal Deposit Insurance Corporation Improvement Act of 1991.

RISK MANAGEMENT
 
The Corporation assumes various types of risk in the normal course of business. Management classifies the risk exposures into five areas: (1) credit, (2) market and liquidity, (3) operational, (4) compliance and (5) business risks; and employs, or is in the process of employing, various risk management processes to identify, measure, monitor and control these risks, as described below.
 
The Corporation continues to enhance its risk management capabilities with additional processes, tools and systems designed to provide management with deeper insight into the Corporation’s various risks, enhance the Corporation’s ability to control those risks, and ensure that appropriate compensation is received for the risks taken.
 
Specialized risk managers, along with the risk management committees in credit, market and liquidity, operational and compliance are responsible for the day-to-day management of those respective risks. The Corporation’s Enterprise-Wide Risk Management Committee is responsible for establishing the governance over the risk management process as well as providing oversight in managing the Corporation’s aggregate risk position. The Enterprise-Wide Risk Management Committee is principally made up of the various managers from the different risk areas and business units and has reporting responsibility to the Enterprise Risk Committee of the Board.
 
Credit Risk
 
Credit risk represents the risk of loss due to failure of a customer or counterparty to meet its financial obligations in accordance with contractual terms. The Corporation manages credit risk through underwriting, periodically reviewing, and approving its credit exposures using Board committee approved credit policies and guidelines. Additionally, the Corporation manages credit risk through loan sales and loan portfolio diversification, limiting exposure to any single industry, customer or guarantor, and selling participations and/or syndicating credit exposures above those levels it deems prudent to third parties.
 
During 2006, the Corporation continued its focus on the credit components of the previously described enterprise-wide risk management program. A two-factor risk rating system was implemented across all business segments in 2005. As of December 2005, substantially all of the loan portfolios were rated using the two-factor system. During 2006, the system was introduced into the Corporation’s decision-making process. The evaluation of the Corporation’s loan portfolios with the new tools is anticipated to provide improved measurement of the potential risks within the loan portfolios. Enhancements in the analytics related to capital modeling, migration, credit loss forecasting and stress testing analysis continued in 2006 and builds a foundation upon which the performance analysis of the new ratings will be added.

The allowance for credit losses includes both the allowance for loan losses and the allowance for credit losses on lending-related commitments. The allowance for loan losses represents management’s assessment of probable losses inherent in the Corporation’s loan portfolio. The allowance for loan losses provides for probable losses that have been identified with specific customer relationships and for probable losses believed to be inherent in the loan portfolio, but that have not been specifically identified. Internal risk ratings are assigned to each business loan at the time of approval and are subject to subsequent periodic reviews by the Corporation’s senior management. The Corporation performs a detailed credit quality review quarterly on both large business and certain large personal purpose consumer and residential mortgage loans that have deteriorated below certain levels of credit risk, and may allocate a specific portion of the allowance to such loans based upon this review. The Corporation defines business loans as those belonging to the commercial, real estate construction, commercial mortgage, lease financing and international loan portfolios. A portion of the allowance is allocated to the remaining business loans by applying projected loss ratios, based on numerous factors identified below, to the loans within each risk rating. In addition, a portion of the allowance is allocated to these remaining loans based on industry specific risks inherent in certain portfolios, including portfolio exposures to automotive, contractor, technology-related, entertainment and air transportation industries, real estate, and Small Business Administration loans. The portion of the allowance allocated to all other consumer and residential mortgage loans is determined by applying projected loss ratios to various segments of the loan portfolio. Projected loss ratios for all portfolios incorporate factors, such as recent charge-off experience, current economic conditions and trends, and trends with respect to past due and nonaccrual amounts, and are supported by underlying analysis, including information on migration and loss given default studies from each of the three major domestic geographic markets (Midwest, Western, and Texas), as well as mapping to bond tables. The allowance for credit losses on lending-related commitments, included in “accrued expenses and other liabilities” on the consolidated balance sheets, provides for probable credit losses inherent in lending-related commitments, including unused commitments to extend credit, letters of credit and financial guarantees. Lending-related commitments for which it is probable that the commitment will be drawn (or sold) are reserved with the same projected loss rates as loans, or with specific reserves. In general, the probability of draw is considered certain once the credit becomes a watch list credit. Non-watch list credits have a lower probability of draw, to which standard loan loss rates are applied.
 
The total allowance for loan losses was $493 million at December 31, 2006, compared to $516 million at December 31, 2005. The allocated portion of the allowance was $464 million at December 31, 2006, an increase of $4 million from year-end 2005. The increase resulted primarily from loan growth, challenges in the automotive industry and the Michigan real estate industry and a leveling off of credit quality improvement trends. An analysis of the changes in the allowance for loan losses is presented in Table 8 on page 45 of this financial review. The allowance for credit losses on lending-related commitments was $26 million at December 31, 2006, compared to $33 million at December 31, 2005, a decrease of $7 million, resulting primarily from a decrease in specific reserves related to unused commitments to extend credit to customers in the automotive industry due to reduced reserve needs resulting from improved market values for unfunded commitments to certain automotive customers. An analysis of the changes in the allowance for credit losses on lending-related commitments is presented on page 45 of this financial review.

Actual loss ratios experienced in the future may vary from those projected. The uncertainty occurs because factors may exist which affect the determination of probable losses inherent in the loan portfolio and are not necessarily captured by the application of projected loss ratios or identified industry specific risks. An unallocated portion of the allowance is maintained to capture these probable losses. The unallocated allowance reflects management’s view that the allowance should recognize the margin for error inherent in the process of estimating expected loan losses. Factors that were considered in the evaluation of the adequacy of the Corporation’s unallocated allowance include the inherent imprecision in the risk rating system and the risk associated with new customer relationships. The unallocated allowance associated with the margin for inherent imprecision covers probable loan losses as a result of an inaccuracy in assigning risk ratings or stale ratings which may not have been updated for recent negative trends in the particular credits. The unallocated allowance due to new business migration risk is based on an evaluation of the risk of rating downgrades associated with loans that do not have a full year of payment history. The unallocated allowance was $29 million at December 31, 2006, a decrease of $27 million from year-end 2005. This decrease was primarily due to reduced new business migration risk reserves based on improved data, as well as improved risk rating accuracy in the Corporation’s commercial loan portfolio.
 
The total allowance, including the unallocated amount, is available to absorb losses from any segment within the portfolio. Unanticipated economic events, including political, economic and regulatory instability in countries where the Corporation has loans, could cause changes in the credit characteristics of the portfolio and result in an unanticipated increase in the allocated allowance. Inclusion of other industry specific portfolio exposures in the allocated allowance, as well as significant increases in the current portfolio exposures, could also increase the amount of the allocated allowance. Any of these events, or some combination thereof, may result in the need for additional provision for loan losses in order to maintain an allowance that complies with credit risk and accounting policies.
 
The allowance as a percentage of total loans, nonperforming assets and annual net loan charge-offs is provided in the following table.

The allowance for loan losses as a percentage of total period-end loans decreased to 1.04 percent at December 31, 2006, from 1.19 percent at December 31, 2005. The allowance for loan losses as a percentage of nonperforming assets decreased to 213 percent at December 31, 2006, from 319 percent at December 31, 2005. The decrease in allowance coverage of total loans and allowance coverage of nonperforming assets resulted primarily from the $23 million reduction in the allowance during 2006, combined with $4.2 billion of loan growth and a $70 million increase in nonperforming assets during the year. The allowance for loan losses as a percentage of net loan charge-offs increased to 822 percent for the year ended December 31, 2006, compared to 469 percent for the prior year, as a result of lower levels of net loan charge-offs in 2006.
 
Management expects full-year 2007 average net credit-related charge-offs as a percentage of average loans to be about 20 basis points.

Nonperforming Assets
 
Nonperforming assets include loans and loans held-for-sale on nonaccrual status, loans which have been renegotiated to less than market rates due to a serious weakening of the borrower’s financial condition, real estate which has been acquired primarily through foreclosure and is awaiting disposition (Other Real Estate or ORE) and debt securities on nonaccrual status.

Consumer loans, except for certain large personal purpose consumer and residential mortgage loans, are charged-off no later than 180 days past due, and earlier, if deemed uncollectible. Loans, other than consumer loans, and debt securities are generally placed on nonaccrual status when management determines that principal or interest may not be fully collectible, but no later than 90 days past due on principal or interest, unless the loan or debt security is fully collateralized and in the process of collection. Loan amounts in excess of probable future cash collections are charged-off to an amount that management ultimately expects to collect. Interest previously accrued but not collected on nonaccrual loans is charged against current income at the time the loan is placed on nonaccrual. Income on such loans is then recognized only to the extent that cash is received and where the future collection of principal is probable. Loans that have been restructured to yield a rate that was equal to or greater than the rate charged for new loans with comparable risk and have met the requirements for a return to accrual status are not included in nonperforming assets. However, such loans may be required to be evaluated for impairment. Refer to Note 4 of the consolidated financial statements on page 80 for a further discussion of impaired loans.
 
Nonperforming assets increased $70 million, or 43 percent, to $232 million at December 31, 2006, from $162 million at December 31, 2005. As shown in Table 10 above, nonaccrual loans increased $76 million, or 54 percent, to $214 million at December 31, 2006, from $138 million at December 31, 2005. ORE decreased $6 million, to $18 million at December 31, 2006, from $24 million at December 31, 2005. There were no nonaccrual debt securities at December 31, 2006 or 2005. The $76 million increase in nonaccrual loans at December 31, 2006 from year-end 2005 levels resulted primarily from a $37 million increase in nonaccrual commercial mortgage loans, a $32 million increase in nonaccrual commercial loans, and a $17 million increase in nonaccrual real estate construction loans, partially offset by a $6 million decrease in nonaccrual international loans. An analysis of nonaccrual loans at December 31, 2006, based primarily on the Standard Industrial Classification (SIC) code, is presented on page 50 of this financial review. Loans past due 90 days or more and still on accrual status decreased $2 million, to $14 million at December 31, 2006, from $16 million at December 31, 2005. Nonperforming assets as a percentage of total loans, other real estate and nonaccrual debt securities was 0.49 percent and 0.37 percent at December 31, 2006 and 2005, respectively.

Loan relationships with balances greater than $2 million transferred to nonaccrual status decreased $46 million, or 21 percent, to $176 million in 2006, compared to $222 million in 2005. There were eight loan relationships greater than $10 million transferred to nonaccrual in 2006. These loans totaled $104 million and were to companies in the wholesale trade ($39 million), automotive ($26 million), real estate ($26 million) and retail trade ($13 million) industries.
 
The Corporation sold $9 million of nonaccrual business loans in 2006. These loans were to customers in the manufacturing industry. In addition, the Corporation sold $114 million of unused commitments in 2006, including $112 million with customers in the automotive industry. The losses associated with the sale of the unused commitments were charged to the “provision for credit losses on lending-related commitments” on the consolidated statements of income.
 
Nonaccrual loan payments/other, as shown in the table above, decreased $171 million in 2006, when compared to 2005. The decrease was mostly due to a decline in payments received on nonaccrual loans greater than $2 million in 2006, compared to 2005, resulting in part from the changes in the levels of nonaccrual loans greater than $2 million in 2006 compared to 2005.
 
The following table presents a summary of total internally classified watch list loans (generally consistent with regulatory defined special mention, substandard and doubtful loans) at December 31, 2006. Consistent with the increase in nonaccrual loans from December 31, 2005 to December 31, 2006, total watch list loans increased both in dollars and as a percentage of the total loan portfolio.

SNC nonaccrual loans comprised less than one percent and approximately 10 percent of total nonaccrual loans at December 31, 2006 and 2005, respectively. As a percentage of total loans, SNC loans represented approximately 19 percent and 15 percent at December 31, 2006 and 2005, respectively. SNC loan net charge-offs were $2 million in 2006, compared to net charge-offs of $4 million in 2005.

The increase in the carrying value of nonaccrual loans as a percentage of contractual value in 2006, when compared to 2005, reflected a stronger focus in recent years on exiting under-collateralized loan relationships prior to the loan reaching nonaccrual status, either through secondary debt market sales or aggressively encouraging those borrowers to find other sources of financing.
 
Concentration of Credit
 
Loans to borrowers in the automotive industry represented the largest significant industry concentration at December 31, 2006 and 2005. Loans to dealers and to borrowers involved with automotive production are reported as automotive, since management believes these loans have similar economic characteristics that might cause them to react similarly to changes in economic conditions. This aggregation involves the exercise of judgment. Included in automotive production are: (a) original equipment manufacturers and Tier 1 and Tier 2 suppliers that produce components used in vehicles and whose primary revenue source is automotive-related (primary defined as greater than 50%) and (b) other manufacturers that produce components used in vehicles and whose primary revenue source is automotive-related. Loans less than $1 million and loans recorded in the Small Business division were excluded from the definition. Foreign ownership consists of North American affiliates of foreign automakers and suppliers.

At December 31, 2006, dealer loans, as shown in the table above, totaled $5.6 billion, of which approximately $2.9 billion, or 51 percent, was to foreign franchises, $2.1 billion, or 38 percent, was to domestic franchises and $627 million, or 11 percent, was to other. Other includes obligations where a primary franchise was indeterminable, such as loans to large public dealership consolidators, and rental car, leasing, heavy truck and recreation vehicle companies.
 
Nonaccrual loans to automotive borrowers comprised approximately 22 percent of total nonaccrual loans at December 31, 2006. The largest automotive loan on nonaccrual status at December 31, 2006 was $14 million. Total automotive net loan charge-offs were $4 million in 2006. The largest automotive net loan charge-off during

Commercial Real Estate Lending
 
The Corporation takes measures to limit risk inherent in its commercial real estate lending activities. These measures include limiting exposure to those borrowers directly involved in the commercial real estate markets and adherence to policies requiring conservative loan-to-value ratios for such loans. Commercial real estate loans, consisting of real estate construction and commercial mortgage loans, totaled $13.9 billion at December 31, 2006, of which $5.0 billion, or 36 percent, were to borrowers in the Commercial Real Estate business line.
 
The real estate construction loan portfolio contains loans primarily made to long-time customers with satisfactory completion experience. The portfolio totaled $4.2 billion and included approximately 1,825 loans, of which 55 percent had balances less than $1 million at December 31, 2006. The largest real estate construction loan had a balance of approximately $68 million at December 31, 2006. The commercial mortgage loan portfolio totaled $9.7 billion at December 31, 2006. The portfolio included approximately 8,875 loans, of which 74 percent had balances of less than $1 million, at December 31, 2006. The largest commercial mortgage loan had a balance of approximately $59 million at December 31, 2006.
 
The geographic distribution of commercial real estate loan borrowers is an important factor in diversifying credit risk. The following table indicates, by location of lending office, the diversification of the Corporation’s commercial real estate loan portfolio.

because of an inability to liquidate assets or obtain adequate funding; and the inability to easily unwind or offset specific exposures without significantly lowering prices because of inadequate market depth or market disruptions.
 
The Asset and Liability Policy Committee (ALPC) establishes and monitors compliance with the policies and risk limits pertaining to market risk management activities. The ALPC meets regularly to discuss and review market risk management strategies and is comprised of executive and senior management from various areas of the Corporation, including finance, lending, deposit gathering and risk management.
 
Interest Rate Risk
 
Interest rate risk arises primarily through the Corporation’s core business activities of extending loans and accepting deposits. The Corporation actively manages its exposure to interest rate risk. The principal objective of interest rate risk management is to maximize net interest income while operating within acceptable limits established for interest rate risk and maintaining adequate levels of funding and liquidity. The Corporation utilizes various types of financial instruments to manage the extent to which net interest income may be affected by fluctuations in interest rates.
 
Interest Rate Sensitivity
 
Interest rate risk arises in the normal course of business due to differences in the repricing and cash flow characteristics of assets and liabilities. Since no single measurement system satisfies all management objectives, a combination of techniques is used to manage interest rate risk. These techniques examine earnings at risk and economic value of equity utilizing multiple simulation analyses.
 
The Corporation frequently evaluates net interest income under various balance sheet and interest rate scenarios, using simulation modeling analysis as its principal risk management evaluation technique. The results of these analyses provide the information needed to assess the balance sheet structure. Changes in economic activity, different from those management included in its simulation analyses, whether domestically or internationally, could translate into a materially different interest rate environment than currently expected. Management evaluates “base” net interest income under what is believed to be the most likely balance sheet structure and interest rate environment. The most likely interest rate environment is derived from management’s forecast for the next 12 months. This “base” net interest income is then evaluated against non-parallel interest rate scenarios that increase and decrease 200 basis points (but no lower than zero percent) from the most likely rate environment. Since movement is from the most likely rate environment, actual movement from the current rates may be more or less than 200 basis points. For this analysis, the rise or decline in interest rates occurs in a linear fashion over four months. In addition, adjustments to asset prepayment levels, yield curves, and overall balance sheet mix and growth assumptions are made to be consistent with each interest rate environment. These assumptions are inherently uncertain and, as a result, the model cannot precisely predict the impact of higher or lower interest rates on net interest income. Actual results may differ from simulated results due to timing, magnitude and frequency of interest rate changes and changes in market conditions and management strategies, among other factors. However, the model can indicate the likely direction of change. Derivative instruments entered into for risk management purposes are included in these analyses. The table below as of December 31, 2006 and December 31, 2005 displays the estimated impact on net interest income during the next 12 months as it relates the most likely scenario results to those from the 200 basis point non-parallel shock described above.

sensitivity from December 31, 2005 to December 31, 2006 was primarily a result of loan and deposit growth, activities in the Financial Services Division and competitive pricing. In addition, a variety of alternative scenarios are performed to assist in the portrayal of the Corporation’s interest rate risk position, including, but not limited to, flat balance sheet and rates, 200 basis point parallel rate shocks and yield curve twists. Changes in interest rates will continue to impact the Corporation’s net interest income in 2007. This interest rate risk will be actively managed through the use of on- and off-balance sheet financial instruments so that the desired risk profile is achieved.
 
In addition to the simulation analysis, an economic value of equity analysis is performed for a longer term view of the interest rate risk position. The economic value of equity analysis begins with an estimate of the mark-to-market valuation of the Corporation’s balance sheet and then applies the estimated market value impact of rate movements upon the assets and liabilities. The economic value of equity is then calculated as the residual necessary to re-balance the resulting assets and liabilities. The market value change in the economic value of equity is then compared to the corporate policy guideline limiting such adverse change to 10 percent of the base economic value of equity as a result of a parallel 200 basis point increase or decrease in interest rates. The Corporation is operating within this policy parameter. As with net interest income shocks, a variety of alternative scenarios are performed to measure the impact on economic value of equity, including, but not limited to, changes in balance sheet structure and yield curve twists.

The change in economic value of equity sensitivity from December 31, 2005 to December 31, 2006 was primarily due to changes in loan and funding mix, and a reduction in interest rate swaps, due to maturing swaps not replaced in 2006.
 
The Corporation uses investment securities and derivative instruments, predominantly interest rate swaps, as asset and liability management tools with the overall objective of mitigating the adverse impact to net interest income from changes in interest rates. These swaps modify the interest rate characteristics of certain assets and liabilities (e.g., from a floating rate to a fixed rate, from a fixed rate to a floating rate or from one floating rate index to another). This strategy assists management in achieving interest rate risk management objectives.

The notional amount of risk management interest rate swaps totaled $8.5 billion at December 31, 2006, and $11.5 billion at December 31, 2005. The decrease in notional amount of $3.0 billion from December 31, 2005 to December 31, 2006 reflects diminished interest rate risk in the core balance sheet due to changes in balance sheet mix, particularly with non-specific maturity deposits. The fair value of risk management interest rate swaps was a net unrealized loss of $19 million at December 31, 2006, compared to a net unrealized loss of $41 million at December 31, 2005.
 
For the year ended December 31, 2006, risk management interest rate swaps generated $108 million of net interest expense, compared to $57 million of net interest income for the year ended December 31, 2005. The lower swap income for 2006, compared to 2005, was primarily due to the rising short-term rate environment in 2005 and 2006, which caused swaps initiated in prior years that receive a fixed rate and pay a floating rate to generate negative spreads.
 
Table 11 below summarizes the expected maturity distribution of the notional amount of risk management interest rate swaps and provides the weighted average interest rates associated with amounts to be received or paid as of December 31, 2006. Swaps have been grouped by asset and liability designation.
 
In addition to interest rate swaps, the Corporation employs various other types of derivative instruments to mitigate exposures to interest rate and foreign currency risks associated with specific assets and liabilities (e.g., loans or deposits denominated in foreign currencies). Such instruments may include interest rate caps and floors, purchased put options, foreign exchange forward contracts and foreign exchange swap agreements. The aggregate notional amounts of these risk management derivative instruments at December 31, 2006 and 2005 were $551 million and $411 million, respectively.
 
Further information regarding risk management derivative instruments is provided in Notes 1, 11, and 20 to the consolidated financial statements on pages 70, 86 and 102, respectively.

The Corporation writes and purchases interest rate caps and enters into foreign exchange contracts, interest rate swaps and energy derivative contracts to accommodate the needs of customers requesting such services. Customer-initiated and other notional activity represented 51 percent of total derivative instruments, including commitments to purchase and sell securities, at December 31, 2006, compared to 47 percent at December 31, 2005. Refer to Notes 1 and 20 of the consolidated financial statements on pages 70 and 102, respectively, for further information regarding customer-initiated and other derivative instruments.
 
Warrants
 
The Corporation holds a portfolio of approximately 790 warrants for generally non-marketable equity securities. These warrants are primarily from high technology, non-public companies obtained as part of the loan origination process. As discussed in Note 1 to the consolidated financial statements on page 70, warrants that have a net exercise provision embedded in the warrant agreement are required to be accounted for as derivatives and recorded at fair value. The value of all warrants that are carried at fair value ($26 million at December 31, 2006) is at risk to changes in equity markets, general economic conditions and other factors. For further information regarding the valuation of warrants accounted for as derivatives, refer to the “Critical Accounting Policies” section of this financial review on page 60.
 
Liquidity Risk and Off-Balance Sheet Arrangements
 
Liquidity is the ability to meet financial obligations through the maturity or sale of existing assets or the acquisition of additional funds. The Corporation has various financial obligations, including contractual obligations and commercial commitments, which may require future cash payments. The following contractual obligations table summarizes the Corporation’s noncancelable contractual obligations and future required minimum payments. Refer to Notes 7, 10 and 11 of the financial statements on pages 83, 85 and 86, respectively, for a further discussion of these contractual obligations.

Since many of these commitments expire without being drawn upon, the total amount of these commercial commitments does not necessarily represent the future cash requirements of the Corporation. Refer to the “Other Market Risks” section below and Note 20 of the consolidated financial statements on page 102 for a further discussion of these commercial commitments.
 
The Corporation also holds a significant interest in certain variable interest entities (VIE’s), in which it is not the primary beneficiary, and does not consolidate. The Corporation defines a significant interest in a VIE as a subordinated interest that exposes it to a significant portion of the VIE’s expected losses or residual returns. In general, a VIE is an entity that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. If any of these characteristics is present, the entity is subject to a variable interests consolidation model, and consolidation is based on variable interests, not on ownership of the entity’s outstanding voting stock. Variable interests are defined as contractual, ownership, or other monetary interests in an entity that change with fluctuations in the entity’s net asset value. A company must

Table of Contents

consolidate an entity depending on whether the entity is a voting rights entity or a VIE. Refer to the “principles of consolidation” section in Note 1 of the consolidated financial statements on page 70 for a summarization of the Corporation’s consolidation policy. Also refer to Note 22 of the consolidated financial statements on page 110 for a discussion of the Corporation’s involvement in VIEs, including those in which it holds a significant interest but for which it is not the primary beneficiary.
 
Liquidity requirements are satisfied with various funding sources. First, the Corporation accesses the purchased funds market regularly to meet funding needs. Purchased funds, comprised of customer certificates of deposit of $100,000 and over that mature in less than one year, institutional certificates of deposit, foreign office time deposits and short-term borrowings, approximated $9.3 billion at December 31, 2006, compared to $3.5 billion and $2.9 billion at December 31, 2005 and 2004, respectively. Second, two medium-term note programs, a $15 billion senior note program and a $2 billion European note program, allow the principal banking subsidiary to issue debt with maturities between one month and 30 years. At year-end 2006, unissued debt relating to the two medium-term note programs totaled $14.3 billion. A third source, if needed, would be liquid assets, including cash and due from banks, federal funds sold and securities purchased under agreements to resell, other short-term investments, and investment securities available-for-sale, which totaled $8.1 billion at December 31, 2006. Additionally, the Corporation also had available $16.0 billion from a collateralized borrowing account with the Federal Reserve Bank at December 31, 2006.
 
The parent company held $122 million of cash and cash equivalents and $246 million of short-term investments with a subsidiary bank at December 31, 2006. In addition, the parent company had available $250 million of borrowing capacity under an unused commercial paper facility at December 31, 2006. Refer to Note 10 of the consolidated financial statements on page 85 for further information on the unused commercial paper facility. Another source of liquidity for the parent company is dividends from its subsidiaries. As discussed in Note 19 to the consolidated financial statements on page 101, banking subsidiaries are subject to regulation and may be limited in their ability to pay dividends or transfer funds to the holding company. During 2007, the banking subsidiaries can pay dividends up to $261 million plus 2007 net profits without prior regulatory approval. One measure of current parent company liquidity is investment in subsidiaries as a percentage of shareholders’ equity. An amount over 100 percent represents the reliance on subsidiary dividends to repay liabilities. As of December 31, 2006, the ratio was 108 percent.
 
The Corporation regularly evaluates its ability to meet funding needs in unanticipated, stress environments. In conjunction with the quarterly 200 basis point interest rate shock analyses, discussed in the “Interest Rate Sensitivity” section on page 53 of this financial review, liquidity ratios and potential funding availability are examined. Each quarter, the Corporation also evaluates its ability to meet liquidity needs under a series of broad events, distinguished in terms of duration and severity. The evaluation projects that sufficient sources of liquidity are available in each series of events.
 
Other Market Risks
 
The Corporation’s market risk related to trading instruments is not significant, as trading activities are limited. Certain components of the Corporation’s noninterest income, primarily fiduciary income, are at risk to fluctuations in the market values of underlying assets, particularly equity securities. Other components of noninterest income, primarily brokerage fees, are at risk to changes in the level of market activity.
 
Share-based compensation expense recognized by the Corporation is dependent upon the fair value of stock options and restricted stock at the date of grant. The fair value of both stock options and restricted stock is impacted by the market price of the Corporation’s stock on the date of grant and is at risk to changes in equity markets, general economic conditions and other factors. For further information regarding the valuation of stock options and restricted stock, refer to the “Critical Accounting Policies” section of this financial review on page 60.
 
Indirect Private Equity and Venture Capital Investments
 
At December 31, 2006, the Corporation had an $87 million portfolio of indirect (through funds) private equity and venture capital investments, and had commitments of $40 million to fund additional investments in future periods. The value of these investments is at risk to changes in equity markets, general economic conditions and a variety of other factors. The majority of these investments are not readily marketable, and are reported in other assets. The investments are individually reviewed for impairment on a quarterly basis, by comparing the carrying value to the estimated fair value.

page 60. Approximately $13 million of the underlying equity and debt (primarily equity) in these funds are to companies in the automotive industry. The automotive-related positions do not represent a majority of any one fund’s investments, and therefore, the exposure related to these positions is mitigated by the performance of other investment interests within the fund’s portfolio of companies. Income from unconsolidated indirect private equity and venture capital investments in 2006 was $21 million, which was partially offset by $10 million of write-downs recognized on such investments in 2006. No generic assumption is applied to all investments when evaluating for impairment. The uncertainty in the economy and equity markets may affect the values of the fund investments. The following table provides information on the Corporation’s indirect private equity and venture capital investments portfolio.

Operational Risk
 
Operational risk represents the risk of loss resulting from inadequate or failed internal processes, people and systems, or from external events. The definition includes legal risk, which is the risk of loss resulting from failure to comply with laws and regulations as well as prudent ethical standards and contractual obligations. It also includes the exposure to litigation from all aspects of an institution’s activities. The definition does not include strategic or reputational risks. Although operational losses are experienced by all companies and are routinely incurred in business operations, the Corporation recognizes the need to identify and control operational losses, and seeks to limit losses to a level deemed appropriate by management after considering the nature of the Corporation’s business and the environment in which it operates. Operational risk is mitigated through a system of internal controls that are designed to keep operating risks at appropriate levels. An Operational Risk Management Committee ensures appropriate risk management techniques and systems are maintained. The Corporation has developed a framework that includes a centralized operational risk management function and business/support unit risk coordinators responsible for managing operational risk specific to the respective business lines.
 
In addition, internal audit and financial staff monitors and assesses the overall effectiveness of the system of internal controls on an ongoing basis. Internal Audit reports the results of reviews on the controls and systems to management and the Audit Committee of the Board. The internal audit staff independently supports the Audit Committee oversight process. The Audit Committee serves as an independent extension of the Board.
 
Compliance Risk
 
Compliance risk represents the risk of regulatory sanctions, reputational impact or financial loss resulting from its failure to comply with regulations and standards of good banking practice. Activities which may expose the Corporation to compliance risk include, but are not limited to, those dealing with the prevention of money laundering, privacy and data protection, community reinvestment initiatives, fair lending challenges resulting from the Corporation’s expansion of its banking center network, and employment and tax matters.
 
The Enterprise-Wide Compliance Committee, comprised of senior business unit managers as well as managers responsible for compliance, audit and overall risk, oversees compliance risk. This enterprise-wide approach provides a consistent view of compliance across the organization. The Enterprise-Wide Compliance Committee also ensures that appropriate actions are implemented in business units to mitigate risk to an acceptable level.
 
Business Risk
 
Business risk represents the risk of loss due to impairment of reputation, failure to fully develop and execute business plans, failure to assess current and new opportunities in business, markets and products, and any other event not identified in the defined risk categories of credit, market and liquidity, operational or compliance risks. Mitigation of the various risk elements that represent business risk is achieved through initiatives to help the Corporation better understand and report on the various risks. Wherever quantifiable, the Corporation intends to use situational analysis and other testing techniques to appreciate the scope and extent of these risks.

CRITICAL ACCOUNTING POLICIES
 
The consolidated financial statements are prepared based on the application of accounting policies, the most significant of which are described on page 70 in Note 1 to the consolidated financial statements. These policies require numerous estimates and strategic or economic assumptions, which may prove inaccurate or subject to variations. Changes in underlying factors, assumptions or estimates could have a material impact on the Corporation’s future financial condition and results of operations. The most critical of these significant accounting policies are the policies for allowance for credit losses, pension plan accounting, income taxes and the valuation of restricted stock and stock options, nonmarketable equity securities and warrants. These policies are reviewed with the Audit Committee of the Board and are discussed more fully below.
 
Allowance for Credit Losses
 
The allowance for credit losses (combined allowance for loan losses and allowance for credit losses on lending-related commitments) is calculated with the objective of maintaining a reserve sufficient to absorb estimated probable losses. Management’s determination of the adequacy of the allowance is based on periodic evaluations of the loan portfolio, lending-related commitments, and other relevant factors. However, this evaluation is inherently subjective as it requires an estimate of the loss content for each risk rating and for each impaired loan, an estimate of the amounts and timing of expected future cash flows, an estimate of the value of collateral, including the market value of thinly traded or nonmarketable equity securities, and an estimate of the probability of drawing on unused commitments.
 
Allowance for Loan Losses
 
Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Consistent with this definition, all nonaccrual and reduced-rate loans (with the exception of residential mortgage and consumer loans) are impaired. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value and discounted cash flows. The valuation is reviewed and updated on a quarterly basis. While the determination of fair value may involve estimates, each estimate is unique to the individual loan, and none is individually significant.
 
The portion of the allowance allocated to the remaining loans is determined by applying projected loss ratios to loans in each risk category. Projected loss ratios incorporate factors, such as recent charge-off experience, current economic conditions and trends, and trends with respect to past due and nonaccrual amounts, and are supported by underlying analysis, including information on migration and loss given default studies from each of the three major domestic geographic markets, as well as mapping to bond tables. Since a loss ratio is applied to a large portfolio of loans, any variation between actual and assumed results could be significant. In addition, a portion of the allowance is allocated to these remaining loans based on industry specific risks inherent in certain portfolios, including portfolio exposures to automotive, contractor, technology-related, entertainment, air transportation and real estate industries, as well as Small Business Administration loans.
 
An unallocated allowance is also maintained to cover factors affecting the determination of probable losses inherent in the loan portfolio that are not necessarily captured by the application of projected loss ratios or identified industry specific risks. The unallocated allowance considers the imprecision in the risk rating system and the risk associated with new customer relationships.
 
The principle assumption used in deriving the allowance for loan losses is the estimate of loss content for each risk rating. To illustrate, if recent loss experience dictated that the projected loss ratios would be changed by five percent (of the estimate) across all risk ratings, the allocated allowance as of December 31, 2006 would change by approximately $13 million.
 
Allowance for Credit Losses on Lending-Related Commitments
 
Lending-related commitments for which it is probable that the commitment will be drawn (or sold) are reserved with the same projected loss rates as loans, or with specific reserves. In general, the probability of draw is considered certain once the credit becomes a watch list credit. Non-watch list credits have a lower probability of draw, to which standard loan loss rates are applied.

Automotive Industry Concentration
 
A concentration in loans to the automotive industry could result in significant changes to the allowance for credit losses if assumptions underlying the expected losses differed from actual results. For example, a bankruptcy by a domestic automotive manufacturer could adversely affect the risk ratings of its suppliers, causing actual losses to differ from those expected. The allowance for loan losses included a component for automotive suppliers, which assumed that suppliers who derive a significant portion of their revenue from certain domestic manufacturers would be downgraded by one or two risk ratings in the event of bankruptcy of those domestic manufacturers. If a similar reserve methodology were extended to cover all suppliers to domestic manufacturers, the allowance for loan losses would increase by about $17 million at December 31, 2006. In addition, the allowance for credit losses on lending-related commitments included reserves for losses on certain unfunded commitments to the domestic manufacturers. Each five percentage point fluctuation in the market price (used to determine expected loss) of those unused commitments would change the allowance for credit losses on lending-related commitments by about $8 million at December 31, 2006.
 
For further discussion of the methodology used in the determination of the allowance for credit losses, refer to the “Allowance for Credit Losses” section in this financial review on page 46, and Note 1 to the consolidated financial statements on page 70. To the extent actual outcomes differ from management estimates, additional provision for credit losses may be required that would adversely impact earnings in future periods. A substantial majority of the allocated allowance is assigned to business segments. Any earnings impact resulting from actual outcomes differing from management estimates would primarily affect the Business Bank segment. The unallocated allowance for loan losses is not assigned to business segments, and any earnings impact resulting from actual outcomes differing from management estimates would primarily affect the “Other” category in segment reporting.
 
Pension Plan Accounting
 
The Corporation has defined benefit plans in effect for substantially all full-time employees. Benefits under the plans are based on years of service, age and compensation. Assumptions are made concerning future events that will determine the amount and timing of required benefit payments, funding requirements and pension expense (income). The three major assumptions are the discount rate used in determining the current benefit obligation, the long-term rate of return expected on plan assets and the rate of compensation increase. The assumed discount rate is determined by matching the expected cash flows of the pension plans to a yield curve that is representative of long-term, high-quality fixed income debt instruments as of the measurement date, December 31. The second assumption, long-term rate of return expected on plan assets, is set after considering both long-term returns in the general market and long-term returns experienced by the assets in the plan. The current asset allocation and target asset allocation model for the plans is detailed in Note 16 on page 94. The expected returns on these various asset categories are blended to derive one long-term return assumption. The assets are invested in certain collective investment funds and mutual investment funds administered by Munder Capital Management, equity securities, U.S. Treasury and other Government agency securities, Government-sponsored enterprise securities, corporate bonds and notes and a real estate investment trust. The third assumption, rate of compensation increase, is based on reviewing recent annual pension-eligible compensation increases as well as the expectation of future increases. The Corporation reviews its pension plan assumptions on an annual basis with its actuarial consultants to determine if the assumptions are reasonable and adjusts the assumptions to reflect changes in future expectations.
 
The key actuarial assumptions that will be used to calculate 2007 expense for the defined benefit pension plans are a discount rate of 5.89 percent, a long-term rate of return on assets of 8.25 percent, and a rate of compensation increase of 4.00 percent. Pension expense in 2007 is expected to be approximately $29 million, a decrease of $10 million from the $39 million recorded in 2006, primarily due to changes in the discount rate and plan demographics and progression.

Changing the 2007 key actuarial assumptions discussed above in 25 basis point increments would have the following impact on pension expense in 2007:
 
                 
    25 Basis Point  
Key Actuarial Assumption   Increase     Decrease  
    (in millions)  
 
Discount rate
  $ (5.7 )   $ 5.7  
Long-term rate of return
    (2.8 )     2.8  
Rate of compensation
    2.8       (2.8 )
 
If the assumed long-term return on assets differs from the actual return on assets, the asset gains and losses are incorporated in the market-related value, which is used to determine the expected return on assets, over a five-year period. The Employee Benefits Committee, which is comprised of executive and senior managers from various areas of the Corporation, provides broad asset allocation guidelines to the asset manager, who reports results and investment strategy quarterly to the Committee. Actual asset allocations are compared to target allocations by asset category and investment returns for each class of investment are compared to expected results based on broad market indices.
 
Note 16 on page 94 to the consolidated financial statements contains a table showing the funded status of the qualified defined benefit plan at year-end which was $140 million at December 31, 2006. Due to the long-term nature of pension plan assumptions, actual results may differ significantly from the actuarial-based estimates. Differences between estimates and experience not recovered in the market or by future assumption changes are required to be recorded in shareholders’ equity as part of accumulated other comprehensive income (loss) and amortized to pension expense in future years. For further information, refer to Note 1 to the consolidated financial statements on page 70. The actuarial net loss in the qualified defined benefit plan recognized in accumulated other comprehensive income (loss) at December 31, 2006 was $138 million, net of tax. In 2006, the actual return on plan assets was $123 million, compared to an expected return on plan assets of $89 million. In 2005, the actual return on plan assets was $66 million, compared to an expected return on plan assets of $91 million. The Corporation will make contributions from time to time to the qualified defined benefit plan to mitigate the impact of the actuarial losses on future years. No contributions were made to the plan in 2006. However, additional contributions, to the extent allowable by law, may be made to further mitigate the losses. For the foreseeable future, the Corporation has sufficient liquidity to make such payments.
 
Pension expense is recorded in “employee benefits” expense on the consolidated statements of income, and is allocated to business segments based on the segment’s share of salaries expense. Given the salaries expense included in 2006 segment results, pension expense was allocated approximately 37 percent, 35 percent, 23 percent and five percent to the Retail Bank, Business Bank, Wealth & Institutional Management and Finance segments, respectively, in 2006.
 
Income Taxes
 
The calculation of the Corporation’s income tax provision and related tax accruals is complex and requires the use of estimates and judgments. The provision for income taxes is based on amounts reported in the consolidated statements of income (after exclusion of nontaxable items, principally income on bank-owned life insurance and interest income on state and municipal securities) and includes deferred income taxes on temporary differences between the tax basis and financial reporting basis of assets and liabilities. Accrued taxes represent the net estimated amount due or to be received from taxing jurisdictions currently or in the future and are included in “accrued income and other assets” or “accrued expenses and other liabilities” on the consolidated balance sheets. The Corporation assesses the relative risks and merits of tax positions for various transactions after considering statutes, regulations, judicial precedent and other available information, and maintains tax accruals consistent with these assessments. The Corporation is subject to audit by taxing authorities that could question and/or challenge the tax positions taken by the Corporation. In the event of such a challenge, the Corporation would pursue any disallowed taxes through administrative measures, and if necessary, vigorously defend its position in court in accordance with its view of the law.
 
Included in net deferred taxes are deferred tax assets, which the Corporation’s management believes will be realized in future periods. Deferred tax assets are evaluated for realization based on available evidence and assumptions made regarding future events. In the event that the future taxable income does not occur in the


62


Table of Contents

manner anticipated, other initiatives could be undertaken to preclude the need to recognize a valuation allowance against the deferred tax asset.
 
Changes in the estimate of accrued taxes occur due to changes in tax law, interpretations of existing tax laws, new judicial or regulatory guidance, and the status of examinations conducted by taxing authorities that impact the relative risks and merits of tax positions taken by the Corporation. These changes in the estimate of accrued taxes could be significant to the operating results of the Corporation. For further information on tax accruals and related risks, see Notes 1 and 17 to the consolidated financial statements on pages 70 and 99, respectively.
 
In July 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109,” (FIN 48). FIN 48 provides guidance on measurement, de-recognition of tax benefits, classification, accounting disclosure and transition requirements in accounting for uncertain tax positions. The Corporation will adopt the provisions of FIN 48 in the first quarter 2007. For further discussion of FIN 48, see Note 2 to the consolidated financial statements on page 77.
 
Valuation Methodologies
 
Restricted Stock and Stock Options
 
The fair value of share-based compensation as of the date of grant is recognized as compensation expense on a straight-line basis over the vesting period. In 2006, the Corporation recognized total share-based compensation expense of $57 million. The Corporation used a binomial model to value stock options granted subsequent to March 31, 2005. Substantially all stock options granted in 2005 were valued using a binomial model. Previously, a Black-Scholes option-pricing model was used. Option valuation models require several inputs, including the risk-free interest rate, the expected dividend yield, expected volatility factors of the market price of the Corporation’s common stock and the expected option life. For further discussion on the valuation model inputs, see Note 15 to the consolidated financial statements on page 92. Changes in input assumptions can materially affect the fair value estimates. The option valuation model is sensitive to the market price of the Corporation’s stock at the grant date, which affects the fair value estimates and, therefore, the amount of expense recorded on future grants. Using the number of stock options granted in 2006 and the Corporation’s stock price at December 31, 2006, a $5.00 per share increase in stock price would result in an increase in pretax expense of approximately $2 million, from the assumed base, over the options’ vesting period. The fair value of restricted stock is based on the market price of the Corporation’s stock at the grant date. Using the number of restricted stock awards issued in 2006, a $5.00 per share increase in stock price would result in an increase in pretax expense of approximately $2 million, from the assumed base, over the awards’ vesting period. Refer to Notes 1 and 15 of the consolidated financial statements on pages 70 and 92, respectively, for further discussion of share-based compensation expense.
 
Nonmarketable Equity Securities
 
At December 31, 2006, the Corporation had an $87 million portfolio of indirect (through funds) private equity and venture capital investments, and had commitments to fund additional investments of $40 million in future periods. A majority of these investments are not readily marketable. The investments are individually reviewed for impairment, on a quarterly basis, by comparing the carrying value to the estimated fair value. The Corporation bases its estimates of fair value for the majority of its indirect private equity and venture capital investments on the percentage ownership in the fair value of the entire fund, as reported by the fund management. In general, the Corporation does not have the benefit of the same information regarding the fund’s underlying investments as does fund management. Therefore, after indication that fund management adheres to accepted, sound and recognized valuation techniques, the Corporation generally utilizes the fair values assigned to the underlying portfolio investments by fund management. For those funds where fair value is not reported by fund management, the Corporation derives the fair value of the fund by estimating the fair value of each underlying investment in the fund. In addition to using qualitative information about each underlying investment, as provided by fund management, the Corporation gives consideration to information pertinent to the specific nature of the debt or equity investment, such as relevant market conditions, offering prices, operating results, financial conditions, exit strategy and other qualitative information, as available. The lack of an independent source to validate fair value estimates is an inherent limitation in the valuation process. The amount by which the carrying value exceeds the fair value, that is determined to be other-than-temporary impairment, is charged to current earnings and the carrying value of the investment is written down accordingly. While the determination of


63


Table of Contents

fair value involves estimates, no generic assumption is applied to all investments when evaluating for impairment. As such, each estimate is unique to the individual investment, and none is individually significant. The inherent uncertainty in the process of valuing equity securities for which a ready market is unavailable may cause our estimated values of these securities to differ significantly from the values that would have been derived had a ready market for the securities existed, and those differences could be material. The value of these investments is at risk to changes in equity markets, general economic conditions and a variety of other factors, which could result in an impairment charge in future periods.
 
Warrants
 
The Corporation holds a portfolio of approximately 790 warrants for generally non-marketable equity securities. These warrants are primarily from high technology, non-public companies obtained as part of the loan origination process. Substantially all of the warrants contain a net exercise provision, which requires them to be accounted for as derivatives and recorded at fair value in accordance with the provisions of Implementation Issue 17a of SFAS 133, “Accounting for Derivative Instruments and Hedging Activities.” The fair value of the derivative warrant portfolio is reviewed quarterly and adjustments to the fair value are recorded quarterly in current earnings. Fair value is determined using a Black-Scholes valuation model, which has five inputs: risk-free rate, term, volatility, exercise price, and the per share market value of the underlying company. Key assumptions used in the December 31, 2006 valuation were as follows. The risk-free rate was estimated using the U.S. treasury rate, as of the valuation date, corresponding with the expected term of the warrant. The Corporation used an expected term of one half of the remaining contractual term of each warrant, which averages approximately seven years. Volatility was estimated using an index of comparable publicly traded companies, based on the Standard Industrial Classification codes. Where sufficient financial data exists, a market approach method was utilized to estimate the current value of the underlying company. When quoted market values were not available, an index method was utilized. Under the index method, the subject companies’ values were “rolled-forward” from the inception date through the valuation date based on the change in value of an underlying index of guideline public companies.
 
The fair value of warrants recorded on the Corporation’s consolidated balance sheets represents management’s best estimate of the fair value of these instruments within the framework of existing accounting standards. Changes in the above material assumptions could result in significantly different valuations. For example, the following table demonstrates the effect of changes in the volatility assumption used, currently 60 percent, on the value of warrants required to be carried at fair value:
 
Valuation of Warrants Held at December 31, 2006
 
                 
    Change in Volatility Factor  
    20% Lower     20% Higher  
    (dollar amounts in millions)  
 
Value of all warrants required to be carried at fair value
  $ (2.4 )   $ 2.6  
 
The valuation of warrants is complex and is subject to a certain degree of management judgment. The inherent uncertainty in the process of valuing warrants for which a ready market is unavailable may cause estimated values of these warrant assets to differ significantly from the values that would have been derived had a ready market for the warrant assets existed, and those differences could be material. The use of an alternative valuation methodology or alternative approaches used to calculate material assumptions could result in significantly different estimated values for these assets. In addition, the value of all warrants required to be carried at fair value ($26 million at December 31, 2006) is at risk to changes in equity markets, general economic conditions and other factors.

The Corporation cautions that forward-looking statements are subject to numerous assumptions, risks and uncertainties, which change over time. Forward-looking statements speak only as of the date the statement is made, and the Corporation does not undertake to update forward-looking statements to reflect facts, circumstances, assumptions or events that occur after the date the forward-looking statements are made. Actual results could differ materially from those anticipated in forward-looking statements and future results could differ materially from historical performance.
 
In addition to factors mentioned elsewhere in this report or previously disclosed in the Corporation’s SEC reports (accessible on the SEC’s website at www.sec.gov or on the Corporation’s website at www.comerica.com ), the following factors, among others, could cause actual results to differ materially from forward-looking statements and future results could differ materially from historical performance. The Corporation cautions that these factors are not exclusive.
 
  •  general political, economic or industry conditions, either domestically or internationally, may be less favorable than expected;
 
  •  unfavorable developments concerning credit quality could affect the Corporation’s financial results;
 
  •  industries in which the Corporation has lending concentrations, including, but not limited to, automotive production, could suffer a significant decline which could adversely affect the Corporation;
 
  •  the introductions, withdrawal, success and timing of business initiatives and strategies, including, but not limited to, the opening of new banking centers and plans to grow personal financial services and wealth management, may be less successful or may be different than anticipated. Such a result could adversely affect the Corporation’s business.
 
  •  fluctuations in interest rates could affect the Corporation’s net interest income and balance sheet;
 
  •  customer borrowing, repayment, investment and deposit practices generally may be different than anticipated;
 
  •  management’s ability to maintain and expand customer relationships may differ from expectations;
 
  •  competitive product and pricing pressures among financial institutions within the Corporation’s markets may change;
 
  •  management’s ability to retain key officers and employees may change;
 
  •  legal and regulatory proceedings and related matters with respect to the financial services industry, including those directly involving the Corporation and its subsidiaries, could adversely affect the Corporation or the financial services industry in general;
 
  •  changes in regulation or oversight may have a material adverse impact on the Corporation’s operations;
 
  •  methods of reducing risk exposures might not be effective;
 
  •  there could be terrorist activities or other hostilities, which may adversely affect the general economy, financial and capital markets, specific industries, and the Corporation; and
 
  •  there could be natural disasters, including, but not limited to, hurricanes, tornadoes, earthquakes, fires, floods and the disruption of private or public utilities, which may adversely affect the general economy, financial and capital markets, specific industries, and the Corporation.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Comerica Incorporated and Subsidiaries
 
Note 1 — Summary of Significant Accounting Policies
 
Organization
 
Comerica Incorporated (the Corporation) is a registered financial holding company headquartered in Detroit, Michigan. The Corporation’s major business segments are the Business Bank, the Retail Bank and Wealth & Institutional Management. For further discussion of each business segment, refer to Note 24 on page 114. The core businesses are tailored to each of the Corporation’s four primary geographic markets: Midwest & Other Markets, Western, Texas and Florida. The Corporation and its banking subsidiaries are regulated at both the state and federal levels.
 
The accounting and reporting policies of the Corporation conform to U.S. generally accepted accounting principles and prevailing practices within the banking industry. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates.
 
The following summarizes the significant accounting policies of the Corporation applied in the preparation of the accompanying consolidated financial statements.
 
Principles of Consolidation
 
The consolidated financial statements include the accounts of the Corporation and its subsidiaries after elimination of all significant intercompany accounts and transactions. The financial statements for prior years have been reclassified to conform to current financial statement presentation.
 
The Corporation consolidates variable interest entities (VIE’s) in which it is the primary beneficiary. In general, a VIE is an entity that either (1) has an insufficient amount of equity to carry out its principal activities without additional subordinated financial support, (2) has a group of equity owners that are unable to make significant decisions about its activities or (3) has a group of equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. If any of these characteristics is present, the entity is subject to a variable interests consolidation model, and consolidation is based on variable interests, not on ownership of the entity’s outstanding voting stock. Variable interests are defined as contractual, ownership or other money interests in an entity that change with fluctuations in the entity’s net asset value. The primary beneficiary consolidates the VIE; the primary beneficiary is defined as the enterprise that absorbs a majority of expected losses or receives a majority of residual returns (if the losses or returns occur), or both. The Corporation consolidates entities not determined to be VIE’s when it holds a majority (controlling) interest in the entity’s outstanding voting stock. The minority interest in less than 100% owned consolidated subsidiaries is not material, and is included in “accrued expenses and other liabilities” on the consolidated balance sheets. The related minority interest in earnings which is included in “other noninterest expenses” on the consolidated statements of income was not significant for the year ended December 31, 2006, approximately $4 million for the year ended December 31, 2005 and was not significant for the year ended December 31, 2004.
 
Equity investments in entities that are not VIE’s where the Corporation owns less than a majority (controlling) interest and equity investments in entities that are VIE’s where the Corporation is not the primary beneficiary are not consolidated. Rather, such investments are accounted for using either the equity method or cost method. The equity method is used for investments in a corporate joint venture and investments where the Corporation has the ability to exercise significant influence over the investee’s operation and financial policies, which is generally presumed to exist if the Corporation owns more than 20 percent of the voting interest of the investee. Equity method investments are included in “accrued income and other assets” on the consolidated balance sheets, with income and losses recorded in “other noninterest income” on the consolidated statements of income. Unconsolidated equity investments that do not meet the criteria to be accounted for under the equity method are accounted for under the cost method. Cost method investments in publicly traded companies are included in “investment securities available-for-sale” on the consolidated balance sheets, with income (net of

write-downs) recorded in “net securities gains (losses)” on the consolidated statements of income. Cost method investments in non-publicly traded companies are included in “accrued income and other assets” on the consolidated balance sheets, with income (net of write-downs) recorded in “other noninterest income” on the consolidated statements of income.
 
For further information regarding the Corporation’s investments in VIE’s, refer to Note 22 on page 110.
 
Discontinued Operations
 
Components of the Corporation that have been or will be disposed of by sale that are significant to the consolidated financial statements are accounted for as discontinued operations in all periods presented. For further information on discontinued operations, refer to Note 26 on page 121.
 
Short-term Investments
 
Short-term investments include interest-bearing deposits with banks, trading securities and loans held-for-sale.
 
Trading securities are carried at market value. Realized and unrealized gains or losses on trading securities are included in “other noninterest income” on the consolidated statements of income.
 
Loans held-for-sale, typically residential mortgages and Small Business Administration loans, are carried at the lower of cost or market. Market value is determined in the aggregate for each portfolio.
 
Investment Securities
 
Investment securities held-to-maturity are those securities which the Corporation has the ability and management has the positive intent to hold to maturity as of the balance sheet dates. Investment securities held-to-maturity are stated at cost, adjusted for amortization of premium and accretion of discount.
 
Investment securities that are not considered held-to-maturity are accounted for as securities available-for-sale, and stated at fair value, with unrealized gains and losses, net of income taxes, reported as a separate component of other comprehensive income (loss). Unrealized losses on securities available-for-sale are recognized in earnings if the Corporation does not have the ability or management does not have the intent to hold the securities until market recovery or if full collection of the amounts due according to the contractual terms of the debt is not expected.
 
Gains or losses on the sale of securities are computed based on the adjusted cost of the specific security sold.
 
Allowance for Loan Losses
 
The allowance for loan losses represents management’s assessment of probable losses inherent in the Corporation’s loan portfolio. The allowance provides for probable losses that have been identified with specific customer relationships and for probable losses believed to be inherent in the loan portfolio, but that have not been specifically identified. Internal risk ratings are assigned to each business loan at the time of approval and are subject to subsequent periodic reviews by the Corporation’s senior management. The Corporation performs a detailed credit quality review quarterly on both large business and certain large personal purpose consumer and residential mortgage loans that have deteriorated below certain levels of credit risk, and may allocate a specific portion of the allowance to such loans based upon this review. The Corporation defines business loans as those belonging to the commercial, real estate construction, commercial mortgage, lease financing and international loan portfolios. A portion of the allowance is allocated to the remaining business loans by applying projected loss ratios, based on numerous factors identified below, to the loans within each risk rating. In addition, a portion of the allowance is allocated to these remaining loans based on industry specific risks inherent in certain portfolios, including portfolio exposures to automotive, contractor, technology-related, entertainment and air transportation industries, real estate, and Small Business Administration loans. The portion of the allowance allocated to all other consumer and residential mortgage loans is determined by applying projected loss ratios to various


71


Table of Contents

 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
Comerica Incorporated and Subsidiaries

segments of the loan portfolio. Projected loss ratios for all portfolios incorporate factors, such as recent charge-off experience, current economic conditions and trends, and trends with respect to past due and nonaccrual amounts, and are supported by underlying analysis, including information on migration and loss given default studies from each of the three major domestic geographic markets (Midwest, Western and Texas), as well as mapping to bond tables.
 
Management maintains an unallocated allowance to recognize the uncertainty and inherent imprecision underlying the process of estimating expected loan losses. Determination of the probable losses inherent in the portfolio, which are not necessarily captured by the allocation methodology discussed above, involve the exercise of judgment. Factors that were considered in the evaluation of the adequacy of the Corporation’s unallocated allowance include the inherent imprecision in the risk rating system, and the risk associated with new customer relationships. The unallocated allowance associated with the margin for imprecision in the risk rating system is based on a historical evaluation of the accuracy of the risk ratings associated with loans, while the unallocated allowance due to new business migration risk is based on an evaluation of the risk of ratings downgrades associated with loans that do not have a full year of payment history.
 
The total allowance, including the unallocated amount, is available to absorb losses from any segment within the portfolio. Unanticipated economic events, including political, economic and regulatory instability in countries where the Corporation has loans, could cause changes in the credit characteristics of the portfolio and result in an unanticipated increase in the allocated allowance. Inclusion of other industry specific exposures in the allocated allowance, as well as significant increases in the current portfolio exposures, could also increase the amount of the allocated allowance. Any of these events, or some combination thereof, may result in the need for additional provision for loan losses in order to maintain an allowance that complies with credit risk and accounting policies.
 
Loans deemed uncollectible are charged off and deducted from the allowance. The provision for loan losses and recoveries on loans previously charged off are added to the allowance.
 
Allowance for Credit Losses on Lending-Related Commitments
 
The allowance for credit losses on lending-related commitments covers management’s assessment of probable credit losses inherent in lending-related commitments, including unused commitments to extend credit, letters of credit and financial guarantees. Lending-related commitments for which it is probable that the commitment will be drawn (or sold) are reserved with the same projected loss rates as loans, or with specific reserves. In general, the probability of draw is considered certain once the credit becomes a watch list credit (generally consistent with regulatory defined special mention, substandard and doubtful accounts). Non-watch list credits have a lower probability of draw, to which standard loan loss rates are applied. The allowance for credit losses on lending-related commitments is included in “accrued expenses and other liabilities” on the consolidated balance sheets, with the corresponding charge reflected in “provision for credit losses on lending-related commitments” in the noninterest expenses section on the consolidated statements of income.
 
Nonperforming Assets
 
Nonperforming assets are comprised of loans and debt securities for which the accrual of interest has been discontinued, loans for which the terms have been renegotiated to less than market rates due to a serious weakening of the borrower’s financial condition, and real estate which has been acquired primarily through foreclosure and is awaiting disposition.
 
Loans that have been restructured but yield a rate equal to or greater than the rate charged for new loans with comparable risk and have met the requirements for accrual status are not reported as nonperforming assets. Such loans continue to be evaluated for impairment for the remainder of the calendar year of the restructuring. These loans may be excluded from the impairment assessment in the calendar years subsequent to the restructuring, if not impaired based on the modified terms. See Note 4 on page 80 for additional information on loan impairment.

Consumer loans are generally not placed on nonaccrual status and are charged off no later than 180 days past due, and earlier, if deemed uncollectible. Loans, other than consumer loans, and debt securities are generally placed on nonaccrual status when principal or interest is past due 90 days or more and/or when, in the opinion of management, full collection of principal or interest is unlikely. At the time a loan or debt security is placed on nonaccrual status, interest previously accrued but not collected is charged against current income. Income on such loans and debt securities is then recognized only to the extent that cash is received and where future collection of principal is probable. Generally, a loan or debt security may be returned to accrual status when all delinquent principal and interest have been received and the Corporation expects repayment of the remaining contractual principal and interest, or when the loan or debt security is both well secured and in the process of collection.
 
A nonaccrual loan that is restructured will generally remain on nonaccrual after the restructuring for a period of six months to demonstrate that the borrower can meet the restructured terms. However, sustained payment performance prior to the restructuring or significant events that coincide with the restructuring are included in assessing whether the borrower can meet the restructured terms. These factors may result in the loan being returned to an accrual status at the time of restructuring or upon satisfaction of a shorter performance period. If management is uncertain whether the borrower has the ability to meet the revised payment schedule, the loan remains classified as nonaccrual. Other real estate acquired is carried at the lower of cost or fair value, minus estimated costs to sell. When the property is acquired through foreclosure, any excess of the related loan balance over fair value is charged to the allowance for loan losses. Subsequent write-downs, operating expenses and losses upon sale, if any, are charged to noninterest expenses.
 
Premises and Equipment
 
Premises and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation, computed on the straight-line method, is charged to operations over the estimated useful lives of the assets. The estimated useful lives are generally 10-33 years for premises that the company owns and three to eight years for furniture and equipment. Leasehold improvements are amortized over the terms of their respective leases, or 10 years, whichever is shorter.
 
Software
 
Capitalized software is stated at cost, less accumulated amortization. Capitalized software includes purchased software and capitalizable application development costs associated with internally-developed software. Amortization, computed on the straight-line method, is charged to operations over the estimated useful life of the software, which is generally five years. Capitalized software is included in “accrued income and other assets” on the consolidated balance sheets.
 
Goodwill and Other Intangible Assets
 
Goodwill and identified intangible assets that have an indefinite useful life are subject to impairment testing, which the Corporation conducts annually, or on an interim basis if events or changes in circumstances between annual tests indicate the assets might be impaired. The Corporation performs its annual impairment test for goodwill as of July 1 of each year. The impairment test involves assigning tangible assets and liabilities, identified intangible assets and goodwill to reporting units, which are a subset of the Corporation’s operating segments, and comparing the fair value of each reporting unit to its carrying value. If the fair value is less than the carrying value, a further test is required to measure the amount of impairment.
 
The Corporation reviews finite-lived intangible assets and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable from projected undiscounted net operating cash flows. If the projected undiscounted net operating cash flows are less than the carrying amount, a loss is recognized to reduce the carrying amount to fair value.
 
Additional information regarding goodwill, other intangible assets and impairment policies can be found in Note 8 on page 83.

Share-based Compensation
 
In 2006, the Corporation adopted the provisions of SFAS No. 123 (revised 2004) (SFAS 123(R)), “Share-Based Payment,” using the modified-prospective transition method. Compensation expense is recognized under SFAS 123(R) using the straight-line method over the requisite service period. Measurement and attribution of compensation cost for awards that were granted prior to the date SFAS 123(R) was adopted continue to be based on the estimate of the grant-date fair value and attribution method used under prior accounting guidance. Prior to the adoption of SFAS 123(R), the benefit of tax deductions in excess of recognized compensation costs was reported in net cash provided by operating activities in the consolidated statements of cash flows. SFAS 123(R) requires such excess tax benefits be reported as a cash inflow from financing activities, rather than a cash flow from operating activities; therefore, these amounts for the year ended December 31, 2006 are reported in net cash provided by financing activities in the consolidated statements of cash flows.
 
In 2002, the Corporation adopted the fair value recognition provisions of SFAS 123, “Accounting for Stock-Based Compensation” (SFAS 123) (as amended by SFAS No. 148, “Accounting for Stock-Based CompensationTransition and Disclosure”), which the Corporation applied prospectively to new share-based compensation awards granted to employees after December 31, 2001. Options granted prior to January 1, 2002 were accounted for under the intrinsic value method, as outlined in APB Opinion No. 25, “Accounting for Stock Issued to Employees.” Net income and earnings per share for the year ended December 31, 2006 fully reflect the impact of applying the fair value recognition method to all outstanding and unvested awards. There would have been no effect on reported net income and earnings per share if the fair value method required by SFAS 123 (as amended by SFAS 148) had been applied to all outstanding and unvested awards in 2005. The effect on net income and earnings per share, if the fair value method had been applied to all outstanding and unvested awards in the year ended December 31, 2004 is presented in the following table.

SFAS 123(R) requires that the expense associated with share-based compensation awards be recorded over the requisite service period. The requisite service period is the period an employee is required to provide service in order to vest in the award, which cannot extend beyond the retirement eligible date (the date at which the employee is no longer required to perform any service to receive the share-based compensation). Prior to the adoption of SFAS 123(R), the Corporation recorded the expense associated with share-based compensation awards over the explicit service period (vesting period). Upon retirement, any remaining unrecognized costs related to share-based compensation awards retained after retirement were expensed. Share-based compensation expense, net of related tax effects, would have decreased $6 million in 2006 and increased $2 million and $3 million in 2005 and 2004, respectively, had the requisite service period provisions of SFAS 123(R) been applied on a historical basis.

Applying the requisite service period provisions to all 2006 share-based compensation awards resulted in a net increase of $16 million in compensation expense ($10 million, or $0.06 per diluted share, net of related tax effects) related to these awards in 2006.
 
The Corporation has elected to adopt the alternative transition method provided in the Financial Accounting Standards Board (FASB) Staff Position No. FAS 123(R)-3, “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards,” for calculating the tax effects of share-based compensation under SFAS 123(R). The alternative transition method includes simplified methods to establish the beginning balance of the additional paid-in capital pool (APIC pool) related to the tax effects of employee share-based compensation, and to determine the subsequent impact on the APIC pool and consolidated statements of cash flows of the tax effects of employee share-based compensation awards that were outstanding and fully or partially unvested upon adoption of SFAS 123(R).
 
Further information on the Corporation’s share-based compensation plans is included in Note 15 on page 92.
 
Pension and Other Postretirement Costs
 
On December 31, 2006, the Corporation adopted the provisions of SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R),” (SFAS 158), and recognized in its consolidated balance sheet the funded status of its defined benefit pension and postretirement plans, measured as the difference between the fair value of plan assets and the benefit obligation at December 31, 2006. For a pension plan, the benefit obligation is the projected benefit obligation; for any other postretirement plan, the benefit obligation is the accumulated benefit obligation. The Corporation also recorded prior service costs, net actuarial losses and remaining transition obligations as components of accumulated other comprehensive income (loss), net of tax, at December 31, 2006. Actuarial gains or losses and prior service costs or credits that arise subsequent to December 31, 2006 and are not recognized as components of net periodic benefit cost will be recognized as increases or decreases in other comprehensive income (loss).
 
Pension costs are charged to “employee benefits” expense on the consolidated statements of income and are funded consistent with the requirements of federal laws and regulations. Inherent in the determination of pension costs are assumptions concerning future events that will affect the amount and timing of required benefit payments under the plans. These assumptions include demographic assumptions such as retirement age and death, a compensation rate increase, a discount rate used to determine the current benefit obligation, and a long-term expected return on plan assets. Net periodic pension expense includes service cost, interest cost based on the assumed discount rate, an expected return on plan assets based on an actuarially derived market-related value of assets, amortization of prior service cost and amortization of net actuarial gains or losses. The market-related value used to determine the expected return on plan assets is based on fair value adjusted for the difference between expected returns and actual asset performance. The asset gains and losses are incorporated in the market-related value over a five-year period. Prior service costs include the impact of plan amendments on the liabilities and are amortized over the future service periods of active employees expected to receive benefits under the plan. Actuarial gains and losses result from experience different from that assumed and from changes in assumptions (excluding asset gains and losses not yet reflected in market-related value). Amortization of actuarial gains and losses is included as a component of net periodic pension cost for a year if the actuarial net gain or loss exceeds 10 percent of the greater of the projected benefit obligation or the market-related value of plan assets. If amortization is required, the excess is amortized over the average remaining service period of participating employees expected to receive benefits under the plan.
 
Postretirement benefits are recognized in “employee benefits” expense on the consolidated statements of income during the average remaining service period of participating employees expected to receive benefits under the plan or the average remaining future lifetime of retired participants currently receiving benefits under the plan.
 
For further information regarding SFAS 158 and the Corporation’s pension and other postretirement plans refer to Note 16 on page 94.

Derivative Instruments
 
Derivative instruments are carried at fair value in either, “accrued income and other assets” or “accrued expenses and other liabilities” on the consolidated balance sheets. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument is determined by whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, the Corporation designates the hedging instrument, based upon the exposure being hedged, as either a fair value hedge, cash flow hedge or a hedge of a net investment in a foreign operation. For derivative instruments designated and qualifying as a fair value hedge (i.e., hedging the exposure to changes in the fair value of an asset or a liability or an identified portion thereof that is attributable to a particular risk), the gain or loss on the derivative instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in current earnings during the period of the change in fair values. For derivative instruments that are designated and qualify as a cash flow hedge (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item (i.e., the ineffective portion), if any, is recognized in current earnings during the period of change. For derivative instruments that are designated and qualify as a hedge of a net foreign currency investment in a foreign subsidiary, the gain or loss is reported in other comprehensive income as part of the cumulative translation adjustment to the extent it is effective. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in current earnings during the period of change.
 
If the Corporation determines that a derivative instrument has not been or will not continue to be highly effective as a fair value or cash flow hedge, or that the hedge designation is no longer appropriate, hedge accounting is discontinued. The derivative instrument will continue to be recorded in the consolidated balance sheets at its fair value, with future changes in fair value recognized in noninterest income.
 
Foreign exchange futures and forward contracts, foreign currency options, interest rate caps, interest rate swap agreements and energy derivative contracts executed as a service to customers are not designated as hedging instruments and both the realized and unrealized gains and losses on these instruments are recognized in noninterest income.
 
The Corporation holds a portfolio of warrants for non-marketable equity securities. These warrants are primarily from high technology, non-public companies obtained as part of the loan origination process. Due to a net exercise provision embedded in substantially all of the warrant agreements, the warrants are recorded at fair value. The initial fair value of warrants obtained as part of the loan origination process is deferred and amortized into “interest and fees on loans” on the consolidated statements of income over the life of the loan, in accordance with SFAS 91, “Accounting for Nonrefundable Fees and Costs Associated with Originating or Acquiring Loans and Initial Direct Costs of Leases.” The fair value of these warrants is subsequently adjusted on a quarterly basis, with any changes in fair value recorded in “warrant income” on the consolidated statements of income. Prior to 2005, the Corporation recognized income related to these warrants approximately 30 days prior to the warrant issuer’s publicly traded stock becoming free of restrictions, when a publicly traded company acquired the warrant issuer, or when cash was received. The cumulative adjustment to record the fair value was not material to 2005 or any other prior reporting period.
 
Further information on the Corporation’s derivative instruments is included in Note 20 on page 102.
 
Standby and Commercial Letters of Credit and Financial Guarantees
 
A liability related to certain guarantee contracts or indemnification agreements that contingently require the guarantor to make payments to the guaranteed party is recognized and initially measured at fair value by the guarantor. The initial recognition and measurement provisions were applied by the Corporation on a prospective

basis to guarantees issued or modified subsequent to December 31, 2002. Further information on the Corporation’s obligations under guarantees is included in Note 20 on page 102.
 
Income Taxes
 
The provision for income taxes is based on amounts reported in the statements of income (after exclusion of nontaxable items, principally affordable housing credits, income on bank-owned life insurance and interest income on state and municipal securities) and includes deferred income taxes on temporary differences between the tax basis and financial reporting basis of assets and liabilities. Deferred tax assets are evaluated for realization based on available evidence and assumptions made regarding future events. In the event that the future taxable income does not occur in the manner anticipated, other initiatives could be undertaken to preclude the need to recognize a valuation allowance against the deferred tax asset. The provision for income taxes assigned to discontinued operations is based on statutory rates, adjusted for permanent differences generated by those operations.
 
Statements of Cash Flows
 
Cash and cash equivalents are defined as those amounts included in “cash and due from banks” on the consolidated balance sheets. Cash flows from discontinued operations are reported as separate line items within cash flows from operating, investing and financing activities in the consolidated statements of cash flows.
 
Deferred Distribution Costs
 
Certain mutual fund distribution costs, principally commissions paid to brokers, are capitalized when paid and amortized over six years. Fees that contractually recoup the deferred costs, primarily 12b-1 fees, are received over a 6-8 year period. The net of these fees and amortization is recorded in “income from discontinued operations, net of tax” on the consolidated statements of income. Early redemption fees collected are generally recorded as a reduction to the capitalized costs, unless there is evidence that, on an ongoing basis, amounts collected will exceed the unamortized deferred fee asset.
 
Loan Origination Fees and Costs
 
Loan origination and commitment fees and certain costs are deferred and recognized over the life of the related loan or over the commitment period as a yield adjustment. Loan fees on unused commitments and fees related to loans sold are recognized currently as noninterest income.
 
Other Comprehensive Income (Loss)
 
The Corporation has elected to present information on comprehensive income in the consolidated statements of changes in shareholders’ equity on page 68 and in Note 12 on page 88.
 
Note 2 — Pending Accounting Pronouncements
 
In July 2006, the FASB issued FASB Staff Position No. FAS 13-2, “Accounting for a Change or Projected Change in the Timing of Cash Flows Relating to Income Taxes Generated by a Leveraged Lease Transaction,” (FSP 13-2). FSP 13-2 requires a recalculation of the lease income from the inception of a leveraged lease if, during the lease term, the expected timing of the income tax cash flows generated from a leveraged lease is revised. At adoption of FSP 13-2, recalculations of affected leveraged leases would result in a one-time non-cash charge to be recognized as a change in accounting principle via a cumulative adjustment to the opening balance of retained earnings in the period of adoption. Assuming there is no subsequent change in future periods to total expected cash flows, the amount of the charge, if any, related to the previously recognized lease income would be recognized as income over the remaining lives of the leveraged leases affected by the provision of FSP 13-2. Subsequent changes in future periods to total expected cash flows would require recalculations of affected leveraged leases, and any resulting changes would be recognized in income in the period the change occurs.

FSP 13-2 is effective for fiscal years beginning after December 15, 2006. Accordingly, the Corporation will adopt the provisions of FSP 13-2 in the first quarter 2007, and currently estimates the non-cash after-tax charge to beginning retained earnings to be approximately $47 million, which is expected to be recognized as income over periods ranging from 4 years to 20 years.
 
In July 2006, the FASB also issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109,” (FIN 48). FIN 48 clarifies the accounting for uncertain tax positions in accordance with SFAS 109, “Accounting for Income Taxes,” by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. The minimum recognition threshold requires the Corporation to recognize, in its financial statements, the impact of a tax position if it is more likely than not that the tax position is valid and would be sustained on audit, including resolution of related appeals or litigation processes, if any. Only tax positions that meet the “more likely than not” recognition criteria at the effective date may be recognized or continue to be recognized in the financial statements upon the adoption of FIN 48. The Interpretation provides guidance on measurement, de-recognition of tax benefits, classification, accounting disclosure and transition requirements in accounting for uncertain tax positions. FIN 48 also allows a registrant, upon adoption, to change its financial statement classification of interest and penalties on tax liabilities. Changes in the amount of tax benefits recognized resulting from the application of the provisions of this Interpretation would result in a one-time non-cash adjustment to be recognized as a change in accounting principle via a cumulative adjustment to the opening balance of retained earnings in the period of adoption. Events causing a change in judgment resulting in subsequent recognition, de-recognition or changes in measurement of a tax position previously recognized would be recognized in income in the period the event occurs. FIN 48 is effective for fiscal years beginning after December 15, 2006. Accordingly, the Corporation will adopt the provisions of FIN 48 in the first quarter 2007, and currently estimates the non-cash adjustment to beginning retained earnings will not be material. Additionally, the Corporation will elect to change the classification of interest and penalties on tax liabilities from other noninterest expenses to the provision for income taxes in the consolidated statements of income in the first quarter 2007, and all prior periods will be reclassified.
 
In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements,” (SFAS 157), which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 applies whenever other standards require (or permit) assets or liabilities to be measured at fair value, and therefore, does not expand the use of fair value in any new circumstances. Fair value refers to the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the market in which the Corporation transacts. SFAS 157 clarifies that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. The fair value hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data, for example, the Corporation’s own data. SFAS 157 requires fair value measurements to be separately disclosed by level within the fair value hierarchy. SFAS 157 is effective for fiscal years beginning after November 15, 2007. Accordingly, the Corporation will adopt the provisions of SFAS 157 in the first quarter of 2008. The Corporation is currently evaluating the guidance contained in SFAS 157 to determine the effect adoption of the guidance will have on the Corporation’s financial condition and results of operations.

At December 31, 2006, the Corporation had 146 securities in an unrealized loss position, including 141 Government-sponsored enterprise securities (i.e., FMNA, FHLMC). The unrealized losses resulted from changes in market interest rates, not credit quality. The Corporation has the ability and intent to hold these available-for-sale investment securities until maturity or market price recovery, and full collection of the amounts due according to the contractual terms of the debt is expected; therefore, the Corporation does not consider these investments to be other-than-temporarily impaired at December 31, 2006.
 
The table below summarizes the amortized cost and fair values of debt securities, by contractual maturity (securities with multiple maturity dates are classified in the period of final maturity). Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

This included securities of $880 million pledged with the Federal Reserve Bank to secure actual treasury tax and loan borrowings of $73 million at December 31, 2006, and potential borrowings of up to an additional $777 million. The remaining pledged securities of $824 million are primarily with state and local government agencies to secure $733 million of deposits and other liabilities, including deposits of the State of Michigan of $214 million at December 31, 2006.
 
Note 4 — Nonperforming Assets
 
The following table summarizes nonperforming assets and loans, which generally are contractually past due 90 days or more as to interest or principal payments. Nonperforming assets consist of nonaccrual loans, reduced-rate loans and other real estate. Nonaccrual loans are those on which interest is not being recognized. Reduced-rate loans are those on which interest has been renegotiated to lower than market rates because of the weakened financial condition of the borrower.

A loan is impaired when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement. Consistent with this definition, all nonaccrual and reduced-rate loans (with the exception of residential mortgage and consumer loans) are impaired.
 
Impaired loans at December 31, 2006 were $209 million. Restructured loans which are performing in accordance with their modified terms must be disclosed as impaired for the remainder of the calendar year of the

Those impaired loans not requiring an allowance represent loans for which the fair value of expected repayments or collateral exceeded the recorded investments in such loans. At December 31, 2006, substantially all of the total impaired loans were evaluated based on fair value of related collateral. Remaining loan impairment is based on the present value of expected future cash flows discounted at the loan’s effective interest rate or observable market value.

Note 8 — Goodwill and Other Intangible Assets
 
Goodwill and identified intangible assets that have an indefinite useful life are subject to impairment testing, which the Corporation conducts annually, or on an interim basis if events or changes in circumstances between annual tests indicate the assets might be impaired. The annual test of goodwill and intangible assets that have an indefinite-life, performed as of July 1, 2006 and 2005 did not indicate that an impairment charge was required.
 
In the fourth quarter 2006, the Corporation sold its ownership interest in Munder, a consolidated subsidiary that was part of the Corporation’s asset management reporting unit. Goodwill of $63 million was allocated to the sale in accordance with SFAS No. 142, “Goodwill and Other Intangible Assets” (SFAS 142). Following the sale of Munder, the remaining components of the asset management reporting unit, which were not significant, were combined with another reporting unit and tested for impairment. The test did not indicate an impairment charge was required. In 2005, the Corporation sold its interest in Framlington Group Limited, an unconsolidated subsidiary of Munder. Goodwill of $34 million was allocated to the sale in accordance with SFAS 142. The Corporation has accounted for Munder as a discontinued operation in all periods presented, which is included in the “Other” category for business segment reporting purposes. For additional information regarding discontinued operations, refer to Note 26 on page 121.

In November 2006, Comerica Bank (the Bank), a subsidiary of the Corporation, issued $400 million of 5.75% Subordinated Notes, which are classified in medium- and long-term debt. The notes pay interest on May 21 and November 21 of each year, beginning with May 21, 2007, and mature November 21, 2016. The Bank used the net proceeds for general corporate purposes.
 
In February 2006, the Bank issued an additional $250 million of 5.20% Subordinated Notes under a series initiated in August 2005. The notes are classified in medium-and long-term debt, pay interest on February 22 and August 22 of each year, beginning August 22, 2006, and mature August 22, 2017. The Bank used the net proceeds for general corporate purposes.
 
In August 2005, the Bank exercised its option to redeem, at par, a $250 million, 7.65% Subordinated Note, which was classified in medium- and long-term debt and had a maturity date of 2010.
 
In August 2005, the Bank issued $250 million of 5.20% Subordinated Notes, which are classified in medium- and long-term debt. The notes pay interest on February 22 and August 22 of each year, beginning with February 22, 2006, and mature August 22, 2017. The Bank used the net proceeds for general corporate purposes.
 
The Corporation has a $350 million, 7.60% Subordinated Note and a $55 million, 9.98% Subordinated Note that relate to trust preferred securities issuances held by entities that were deconsolidated, effective July 1, 2003, as a result of the adoption of FIN 46(R). The $350 million, 7.60% Subordinated Note, which became callable effective July 31, 2006, qualifies as Tier 1 capital. In December 2006, the Corporation gave irrevocable notice of its intent to call the $55 million, 9.98% Subordinated Note on June 30, 2007; therefore, the note does not qualify as Tier 1 or Tier 2 capital at December 31, 2006. All other subordinated notes with maturities greater than one year qualify as Tier 2 capital.
 
The Corporation currently has two medium-term note programs: a $15 billion senior note program and a $2 billion European note program. These programs allow the principal banking subsidiary to issue fixed or floating rate notes with maturities between one month and 30 years. The Bank issued a total of $2.7 billion of floating rate bank notes during the second and third quarters of 2006 under the senior note program, using the proceeds to fund loan growth. The interest rate on the floating rate medium-term notes based on LIBOR at December 31, 2006 ranged from one-month LIBOR less 0.03% to three-month LIBOR plus 0.19%. The interest

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
Comerica Incorporated and Subsidiaries

rate on the floating rate medium-term note based on PRIME at December 31, 2006 was PRIME less 2.91%. The medium-term notes outstanding at December 31, 2006 are due from 2007 to 2011. The medium-term notes do not qualify as Tier 2 capital and are not insured by the FDIC.
 
In December 2001, the Corporation privately placed approximately $1.0 billion of variable rate notes as part of a secured financing transaction. The Corporation utilized approximately $1.2 billion of dealer floor plan loans as collateral in conjunction with this transaction. The over-collateralization of the issuance provided for a preferred credit rating status. The secured financing included $924 million of deferred payment notes bearing interest at the rate of 30 basis points plus a commercial paper reference rate, and $60 million of deferred payment notes based on one-month LIBOR. Both deferred payment notes were repaid in full in the fourth quarter 2006.
 
At December 31, 2006, the principal maturities of medium- and long-term debt were as follows:

At December 31, 2006, the Corporation had 32.6 million shares of common stock reserved for issuance and 1.1 million shares of restricted stock outstanding to employees and directors under share-based compensation plans.
 
Note 13 — Accumulated Other Comprehensive Income (Loss)
 
Other comprehensive income (loss) includes the change in net unrealized gains and losses on investment securities available-for-sale, the change in accumulated net gains and losses on cash flow hedges, the change in the accumulated foreign currency translation adjustment and the change in the accumulated defined benefit and other postretirement plans adjustment. The consolidated statements of changes in shareholders’ equity on page 68 include only combined other comprehensive income (loss), net of tax. The following table presents reconciliations of the components of accumulated other comprehensive income (loss) for the years ended December 31, 2006, 2005 and 2004. Total comprehensive income totaled $948 million, $760 million and $614 million for the years ended December 31, 2006, 2005 and 2004, respectively. The $188 million increase in total comprehensive income in the year ended December 31, 2006, when compared to 2005, resulted principally from decreases in net losses on cash flow hedges ($118 million) and net unrealized losses on investment securities available-for-sale ($43 million), due to changes in the interest rate environment, and an increase in net income ($32 million). Accumulated other comprehensive income at December 31, 2006 was also impacted by a $209 million after-tax transition adjustment to apply the provisions of SFAS 158.
 
For a further discussion of the effect of derivative instruments and the effects of SFAS 158 on other comprehensive income (loss) refer to Notes 1, 16 and 20 on pages 70, 94 and 102, respectively.

Note 14 — Net Income Per Common Share
 
Basic income from continuing operations and net income per common share are computed by dividing income from continuing operations and net income applicable to common stock, respectively, by the weighted-average number of shares of common stock outstanding during the period. Diluted income from continuing operations and net income per common share are computed by dividing income from continuing operations and net income applicable to common stock, respectively, by the weighted-average number of shares, nonvested restricted stock and dilutive common stock equivalents outstanding during the period. Common stock equivalents consist of common stock issuable under the assumed exercise of stock options granted under the Corporation’s stock plans, using the treasury stock method. A computation of basic and diluted income from continuing operations and net income per common share are presented in the following table.

Note 15 — Share-Based Compensation
 
Share-based compensation expense is charged to “salaries” expense, except for the Corporation’s Munder subsidiary, which was sold in 2006, whose share-based compensation expense was charged to “income from discontinued operations, net of tax,” on the consolidated statements of income. The components of share-based compensation expense for all share-based compensation plans and related tax benefits are as follows:

The Corporation has share-based compensation plans under which it awards both shares of restricted stock to key executive officers and key personnel, and stock options to executive officers, directors and key personnel of the Corporation and its subsidiaries. Restricted stock vests over periods ranging from three to five years. Stock options vest over periods ranging from one to four years. The maturity of each option is determined at the date of grant; however, no options may be exercised later than ten years and one month from the date of grant. The options may have restrictions regarding exercisability. The plans originally provided for a grant of up to 13.2 million common shares, plus shares under certain plans that are forfeited, expire or are cancelled. At December 31, 2006, 13.4 million shares were available for grant.
 
The Corporation used a binomial model to value stock options granted subsequent to March 31, 2005. Previously, a Black-Scholes option-pricing model was used. Substantially all stock option grants for 2005 occurred in the second quarter 2005 and were valued using the binomial model. Option valuation models require several inputs, including the expected stock price volatility, and changes in input assumptions can materially affect the fair value estimates. The model used may not necessarily provide a reliable single measure of the fair value of employee and director stock options. The risk-free interest rate assumption used in the binomial option-pricing model as outlined in the table below was based on the federal ten-year treasury interest rate. The expected dividend yield was based on the historical and projected dividend yield patterns of the Corporation. Expected volatility assumptions during 2006 considered both the historical volatility of the Corporation’s common stock over a ten-year period and implied volatility based on actively traded options on the Corporation’s common stock with pricing terms and trade dates similar to the stock options granted. Previously, only historical volatility was considered under the binomial model. The expected life of employee and director stock options, which is an output of the binomial model, considered the percentage of vested shares estimated to be cancelled over the life of the grant and was based on the historical exercise behavior of the option holders.

The Corporation expects to satisfy the exercise of stock options and future grants of restricted stock by issuing shares of common stock out of treasury. At December 31, 2006, the Corporation held 21.2 million shares in treasury.
 
For further information on the Corporation’s share-based compensation plans, refer to Note 1 on page 70.
 
Note 16 — Employee Benefit Plans
 
The Corporation has a qualified and a non-qualified defined benefit pension plan, which together, provide benefits for substantially all full-time employees hired before January 1, 2007. A new defined contribution retirement plan will be provided to employees hired by the Corporation on or after January 1, 2007. Employee benefits expense included pension expense of $39 million, $31 million and $16 million in the years ended December 31, 2006, 2005 and 2004, respectively, for the plans. Benefits under the defined benefit plans are based primarily on years of service, age and compensation during the five highest paid consecutive calendar years occurring during the last ten years before retirement. The defined benefit plans’ assets primarily consist of units of certain collective investment funds and mutual investment funds administered by Munder, equity securities, U.S. Treasury and other Government agency securities, Government-sponsored enterprise securities, corporate bonds and notes and a real estate investment trust. The majority of these assets have publicly quoted prices, which is the basis for determining fair value of plan assets.
 
The Corporation’s postretirement benefit plan continues to provide postretirement health care and life insurance benefits for retirees as of December 31, 1992, and life insurance only for retirees after that date. The Corporation has funded the plan with bank-owned life insurance.
 
On December 31, 2006, the Corporation adopted the provisions of SFAS 158. SFAS 158 requires the Corporation to recognize in its consolidated balance sheet the over-funded or under-funded status of its defined benefit pension and postretirement plans, measured as the difference between the fair value of plan assets and the benefit obligation. For a pension plan, the benefit obligation is the projected benefit obligation; for any other postretirement plan, the benefit obligation is the accumulated benefit obligation. SFAS 158 also requires the immediate recognition of unrecognized prior service costs and credits, unrecognized net actuarial gains or losses, and any unrecognized transition obligation or asset as components of other comprehensive income, net of tax.

     The 2006 postretirement benefit plan change of $9 million reflects an adjustment to include certain participant groups not previously included in plan valuations. The plan change of $19 million in 2005 reflects a periodic reallocation of exposure from the non-qualified pension plan to the qualified pension plan. The non-qualified pension plan was the only pension plan with an accumulated benefit obligation in excess of plan assets at December 31, 2006 and 2005.

The long-term rate of return expected on plan assets is set after considering both long-term returns in the general market and long-term returns experienced by the assets in the plan. The returns on the various asset categories are blended to derive one long-term rate of return. The Corporation reviews its pension plan assumptions on an annual basis with its actuarial consultants to determine if assumptions are reasonable and adjusts the assumptions to reflect changes in future expectations.

Plan Assets
 
The Corporation’s qualified defined benefit pension plan asset allocations at December 31, 2006 and 2005 and target allocation for 2007 are shown in the table below. There were no assets in the non-qualified defined benefit pension plan. The postretirement benefit plan is fully invested in bank-owned life insurance policies.

The investment goal for the qualified defined benefit pension plan is to achieve a real rate of return (nominal rate minus consumer price index change) consistent with that received on investment grade corporate bonds. The Corporation’s 2007 target allocation percentages by asset category are noted in the table above. Given the mix of equity securities and fixed income (including cash), management believes that by targeting the benchmark return to an “investment grade” quality return, an appropriate degree of risk is maintained. Within the asset classes, the degree of non-U.S. based assets is limited to 15 percent of the total, to be allocated within both equity securities and fixed income. The investment manager has discretion to make investment decisions within the target allocation parameters. The Corporation’s Employee Benefits Committee must approve exceptions to this policy. Securities issued by the Corporation and its subsidiaries are not eligible for use within this plan.

The Corporation also maintains defined contribution plans (including 401(k) plans) for various groups of its employees. All of the Corporation’s employees are eligible to participate in one or more of the plans. Under the Corporation’s principal defined contribution plan, the Corporation makes matching contributions, most of which are based on a declining percentage of employee contributions (in 2006, the Corporation matched 50 percent of the first $1,000 and 25 percent of the next $2,000 of compensation contributed; the maximum match per employee was $1,000) as well as a performance-based matching contribution based on the Corporation’s financial performance. The Corporation’s match is made in stock of the Corporation, which is restricted until the end of the calendar year, after which the employees may reallocate to other investment options. Employees may choose to invest their contributions in the stock of the Corporation, and may reallocate employee contributions invested in the Corporation’s stock to other investments at any time. Employee benefits expense included expense for the plans of $13 million, $15 million and $13 million in the years ended December 31, 2006, 2005 and 2004, respectively. Effective January 1, 2007, the Corporation prospectively changed its core matching contribution to 100 percent of the first four percent of qualified earnings contributed (up to the current IRS compensation limit) which will be invested based on employee investment elections, rather than in stock of the Corporation, and discontinued the performance-based matching contribution.

The Corporation’s banking subsidiaries have had, and expect to have in the future, transactions with the Corporation’s directors and executive officers, and companies with which these individuals are associated. Such transactions were made in the ordinary course of business and included extensions of credit, leases and professional services. With respect to extensions of credit, all were made on substantially the same terms,

including interest rates and collateral, as those prevailing at the same time for comparable transactions with other customers and did not, in management’s opinion, involve more than normal risk of collectibility or present other unfavorable features. The aggregate amount of loans attributable to persons who were related parties at December 31, 2006, totaled $140 million at the beginning and $216 million at the end of 2006. During 2006, new loans to related parties aggregated $324 million and repayments totaled $248 million.
 
Note 19 — Regulatory Capital and Reserve Requirements
 
Cash and due from banks includes reserves required to be maintained and/or deposited with the Federal Reserve Bank. These reserve balances vary, depending on the level of customer deposits in the Corporation’s banking subsidiaries. The average required reserve balances were $298 million and $289 million for the years ended December 31, 2006 and 2005, respectively.
 
Banking regulations limit the transfer of assets in the form of dividends, loans or advances from the bank subsidiaries to the parent company. Under the most restrictive of these regulations, the aggregate amount of dividends which can be paid to the parent company without obtaining prior approval from bank regulatory agencies approximated $261 million at January 1, 2007, plus 2007 net profits. Substantially all the assets of the Corporation’s banking subsidiaries are restricted from transfer to the parent company of the Corporation in the form of loans or advances.
 
Dividends declared to the parent company of the Corporation by its banking subsidiaries amounted to $746 million, $793 million and $691 million in 2006, 2005 and 2004, respectively.
 
The Corporation and its U.S. banking subsidiaries are subject to various regulatory capital requirements administered by federal and state banking agencies. Quantitative measures established by regulation to ensure capital adequacy require the maintenance of minimum amounts and ratios of Tier 1 and total capital (as defined in the regulations) to average and risk-weighted assets. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s financial statements. At December 31, 2006 and 2005, the Corporation and its U.S. banking subsidiaries exceeded the ratios required for an institution to be considered “well capitalized” (total risk-based capital, Tier 1 risk-based capital and leverage ratios greater than 10 percent, 6 percent and 5 percent, respectively). The following is a summary of the capital position of the Corporation and Comerica Bank, its significant banking subsidiary.

Note 20 — Derivative and Credit-Related Financial Instruments
 
In the normal course of business, the Corporation enters into various transactions involving derivative and credit-related financial instruments to manage exposure to fluctuations in interest rate, foreign currency and other market risks and to meet the financing needs of customers. These financial instruments involve, to varying degrees, elements of credit and market risk.
 
Credit risk is the possible loss that may occur in the event of nonperformance by the counterparty to a financial instrument. The Corporation attempts to minimize credit risk arising from financial instruments by evaluating the creditworthiness of each counterparty, adhering to the same credit approval process used for traditional lending activities. Counterparty risk limits and monitoring procedures have also been established to facilitate the management of credit risk. Collateral is obtained, if deemed necessary, based on the results of management’s credit evaluation. Collateral varies, but may include cash, investment securities, accounts receivable, equipment or real estate.
 
Derivative instruments are traded over an organized exchange or negotiated over-the-counter. Credit risk associated with exchange-traded contracts is typically assumed by the organized exchange. Over-the-counter contracts are tailored to meet the needs of the counterparties involved and, therefore, contain a greater degree of credit risk and liquidity risk than exchange-traded contracts, which have standardized terms and readily available price information. The Corporation reduces exposure to credit and liquidity risks from over-the-counter derivative instruments by conducting such transactions with investment-grade domestic and foreign investment banks or commercial banks.
 
Market risk is the potential loss that may result from movements in interest or foreign currency rates and energy prices, which cause an unfavorable change in the value of a financial instrument. The Corporation manages this risk by establishing monetary exposure limits and monitoring compliance with those limits. Market

risk arising from derivative instruments entered into on behalf of customers is reflected in the consolidated financial statements and may be mitigated by entering into offsetting transactions. Market risk inherent in derivative instruments held or issued for risk management purposes is generally offset by changes in the value of rate sensitive assets or liabilities.
 
Derivative Instruments
 
The Corporation, as an end-user, employs a variety of financial instruments for risk management purposes. Activity related to these instruments is centered predominantly in the interest rate markets and mainly involves interest rate swaps. Various other types of instruments also may be used to manage exposures to market risks, including interest rate caps and floors, total return swaps, foreign exchange forward contracts and foreign exchange swap agreements.
 
For hedge relationships accounted for under SFAS 133 at inception of the hedge, the Corporation uses either the short-cut method if it qualifies, or applies dollar offset or statistical regression analysis to assess effectiveness. The short-cut method is used for fair value hedges of medium and long-term debt. This method allows for the assumption of zero hedge ineffectiveness and eliminates the requirement to further assess hedge effectiveness on these transactions. For SFAS 133 hedge relationships to which the Corporation does not apply the short-cut method, dollar offset or statistical regression analysis is used at inception and for each reporting period thereafter to assess whether the derivative used has been and is expected to be highly effective in offsetting changes in the fair value or cash flows of the hedged item. All components of each derivative instrument’s gain or loss are included in the assessment of hedge effectiveness. Net hedge ineffectiveness is recorded in “other noninterest income” on the consolidated statements of income.
 
The following table presents net hedge ineffectiveness gains (losses) by risk management hedge type:

As part of a fair value hedging strategy, the Corporation has entered into interest rate swap agreements for interest rate risk management purposes. These interest rate swap agreements effectively modify the Corporation’s exposure to interest rate risk by converting fixed-rate deposits and debt to a floating rate. These agreements involve the receipt of fixed rate interest amounts in exchange for floating rate interest payments over the life of the agreement, without an exchange of the underlying principal amount.
 
As part of a cash flow hedging strategy, the Corporation entered into predominantly 2 to 3 year interest rate swap agreements (weighted average original maturity of 2.9 years) that effectively convert a portion of its existing and forecasted floating-rate loans to a fixed-rate basis, thus reducing the impact of interest rate changes on future interest income over the next 2 to 3 years. Approximately 13 percent ($6.2 billion) of the Corporation’s outstanding loans were designated as hedged items to interest rate swap agreements at December 31, 2006. For the year ended December 31, 2006, interest rate swap agreements designated as cash flow hedges decreased interest and fees on loans by $124 million, compared with a decrease of $2 million for the year ended December 31, 2005. If interest rates, interest yield curves and notional amounts remain at their current levels, the Corporation expects to reclassify $42 million of net losses on derivative instruments, that are designated as cash flow hedges, from accumulated other comprehensive income (loss) to earnings during the next twelve months due to receipt of variable interest associated with the existing and forecasted floating-rate loans.

Foreign exchange rate risk arises from changes in the value of certain assets and liabilities denominated in foreign currencies. The Corporation employs cash instruments, such as investment securities, as well as derivative instruments, to manage exposure to these and other risks. In addition, the Corporation uses foreign exchange forward and option contracts to protect the value of its foreign currency investment in foreign subsidiaries. Realized and unrealized gains and losses from foreign exchange forward and option contracts used to protect the value of investments in foreign subsidiaries are not included in the statement of income, but are shown in the accumulated foreign currency translation adjustment account included in other comprehensive income (loss), with the related amounts due to or from counterparties included in other liabilities or other assets. During the year ended December 31, 2006, the Corporation recognized net gains of less than $0.5 million in accumulated foreign currency translation adjustment, related to the foreign exchange forward and option contracts, compared to $4 million of net losses during the year ended December 31, 2005. During the third quarter 2006, the Corporation completed the sale of its Mexican bank charter and reclassified $7 million of related accumulated foreign currency translation loss to “net gain (loss) on sales of businesses” on the consolidated statements of income, in accordance with SFAS 130, “Reporting Comprehensive Income” (as amended). During the fourth quarter 2006, the Corporation completed the sale of its Munder subsidiary and reclassified the remaining accumulated foreign currency translation gain, which was not significant, to “income from discontinued operations, net of tax” on the consolidated statements of income.
 
Management believes these hedging strategies achieve the desired relationship between the rate maturities of assets and funding sources which, in turn, reduces the overall exposure of net interest income to interest rate risk, although, there can be no assurance that such strategies will be successful. The Corporation also may use various other types of financial instruments to mitigate interest rate and foreign currency risks associated with specific assets or liabilities. Such instruments include interest rate caps and floors, foreign exchange forward contracts, foreign exchange option contracts and foreign exchange cross-currency swaps.
 
The following table presents the composition of derivative instruments held or issued for risk management purposes, excluding commitments, at December 31, 2006 and 2005. The fair values of all derivative instruments are reflected in the consolidated balance sheets.

Notional amounts, which represent the extent of involvement in the derivatives market, are generally used to determine the contractual cash flows required in accordance with the terms of the agreement. These amounts are typically not exchanged, significantly exceed amounts subject to credit or market risk, and are not reflected in the consolidated balance sheets.
 
Credit risk, which excludes the effects of any collateral or netting arrangements, is measured as the cost to replace, at current market rates, contracts in a profitable position. The amount of this exposure is represented by the gross unrealized gains on derivative instruments.
 
Bilateral collateral agreements with counterparties covered 76 percent and 85 percent of the notional amount of interest rate derivative contracts at December 31, 2006 and 2005, respectively. These agreements reduce credit risk by providing for the exchange of marketable investment securities to secure amounts due on contracts in an unrealized gain position. In addition, at December 31, 2006, master netting arrangements had been established with all interest rate swap counterparties and certain foreign exchange counterparties. These arrangements effectively reduce credit risk by permitting settlement, on a net basis, of contracts entered into with the same counterparty. The Corporation has not experienced any material credit losses associated with derivative instruments.
 
Fee income is earned from entering into various transactions, principally foreign exchange contracts, interest rate contracts, and energy derivative contracts at the request of customers. The Corporation mitigates market risk inherent in customer-initiated interest rate and energy contracts by taking offsetting positions, except in those circumstances when the amount, tenor and/or contracted rate level results in negligible economic risk, whereby the cost of purchasing an offsetting contract is not economically justifiable. For customer-initiated foreign exchange contracts, the Corporation mitigates most of the inherent market risk by taking offsetting positions and manages the remainder through individual foreign currency position limits and aggregate value-at-risk limits. These limits are established annually and reviewed quarterly.
 
For those customer-initiated derivative contracts which were not offset or where the Corporation holds a speculative position within the limits described above, the Corporation recognized $1 million of net gains in both 2006 and 2005, and $2 million of net gains in 2004, which were included in “other noninterest income” in the consolidated statements of income. The fair value of derivative instruments held or issued in connection with customer-initiated activities, including those customer-initiated derivative contracts where the Corporation does not enter into an offsetting derivative contract position, is included in the following table.

Detailed discussions of each class of derivative instruments held or issued by the Corporation for both risk management and customer-initiated and other activities are as follows.
 
Interest Rate Swaps
 
Interest rate swaps are agreements in which two parties periodically exchange fixed cash payments for variable payments based on a designated market rate or index (or variable payments based on two different rates or indices for basis swaps), applied to a specified notional amount until a stated maturity. The Corporation’s swap agreements are structured such that variable payments are primarily based on prime, one-month LIBOR or three-month LIBOR. These instruments are principally negotiated over-the-counter and are subject to credit risk, market risk and liquidity risk.
 
Interest Rate Options, Including Caps and Floors
 
Option contracts grant the option holder the right to buy or sell an underlying financial instrument for a predetermined price before the contract expires. Interest rate caps and floors are option-based contracts which entitle the buyer to receive cash payments based on the difference between a designated reference rate and the strike price, applied to a notional amount. Written options, primarily caps, expose the Corporation to market risk but not credit risk. A fee is received at inception for assuming the risk of unfavorable changes in interest rates. Purchased options contain both credit and market risk. All interest rate caps and floors entered into by the Corporation are over-the-counter agreements.
 
Foreign Exchange Contracts
 
Foreign exchange contracts such as futures, forwards and options are primarily entered into as a service to customers and to offset market risk arising from such positions. Futures and forward contracts require the delivery or receipt of foreign currency at a specified date and exchange rate. Foreign currency options allow the owner to purchase or sell a foreign currency at a specified date and price. Foreign exchange futures are exchange-traded, while forwards, swaps and most options are negotiated over-the-counter. Foreign exchange contracts expose the Corporation to both market risk and credit risk. The Corporation also uses foreign exchange rate swaps and cross-currency swaps for risk management purposes.
 
Energy Derivative Contracts
 
The Corporation offers energy derivative contracts, including over-the-counter and NYMEX based natural gas and crude oil fixed rate swaps and options as a service to customers seeking to hedge market risk in the underlying products. Contract tenors are typically limited to three years to accommodate hedge requirements and are further limited to products that are liquid and available on demand. Energy derivative swaps are over-the-counter agreements in which the Corporation and the counterparty periodically exchange fixed cash payments for variable payments based upon a designated market price or index. Energy derivative option contracts grant the option owner the right to buy or sell the underlying commodity for a predetermined price at settlement date. Energy caps,

floors and collars are option-based contracts that result in the buyer and seller of the contract receiving or making cash payments based on the difference between a designated reference price and the contracted strike price, applied to a notional amount. An option fee or premium is received by the Corporation at inception for assuming the risk of unfavorable changes in energy commodity prices. Purchased options contain both credit and market risk. Commodity options entered into by the Corporation are over-the-counter agreements.
 
Warrants
 
The Corporation holds a portfolio of approximately 790 warrants for generally non-marketable equity securities. These warrants are primarily from high technology, non-public companies obtained as part of the loan origination process. As discussed in Note 1 on page 70, warrants that have a net exercise provision embedded in the warrant agreement are required to be recorded at fair value. Fair value for these warrants (approximately 680 warrants at December 31, 2006 and 800 warrants at December 31, 2005) was approximately $26 million at December 31, 2006 and $30 million at December 31, 2005, as estimated using a Black-Scholes valuation model.
 
Commitments
 
The Corporation also enters into commitments to purchase or sell earning assets for risk management and trading purposes. These transactions are similar in nature to forward contracts. The Corporation had commitments to purchase investment securities for its trading account totaling $20 million at December 31, 2006, and $6 million at December 31, 2005. Commitments to sell investment securities related to the trading account totaled $16 million at December 31, 2006 and $6 million at December 31, 2005. Outstanding commitments expose the Corporation to both credit and market risk.
 
Credit-Related Financial Instruments
 
The Corporation issues off-balance sheet financial instruments in connection with commercial and consumer lending activities. The Corporation’s credit risk associated with these instruments is represented by the contractual amounts indicated in the following table.

The Corporation maintains an allowance to cover probable credit losses inherent in lending-related commitments, including unused commitments to extend credit, letters of credit and financial guarantees. At December 31, 2006 and 2005, the allowance for credit losses on lending-related commitments, which is recorded in “accrued expenses and other liabilities” on the consolidated balance sheets, was $26 million and $33 million, respectively.

Unused Commitments to Extend Credit
 
Commitments to extend credit are legally binding agreements to lend to a customer, provided there is no violation of any condition established in the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many commitments expire without being drawn upon, the total contractual amount of commitments does not necessarily represent future cash requirements of the Corporation. Commercial and other unused commitments are primarily variable rate commitments.
 
Standby and Commercial Letters of Credit and Financial Guarantees
 
Standby and commercial letters of credit and financial guarantees represent conditional obligations of the Corporation, which guarantee the performance of a customer to a third party. Standby letters of credit and financial guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. Long-term standby letters of credit and financial guarantees are defined as those maturing beyond one year and expire in decreasing amounts through the year 2016.
 
Commercial letters of credit are issued to finance foreign or domestic trade transactions and are short-term in nature. The Corporation may enter into participation arrangements with third parties, which effectively reduce the maximum amount of future payments, which may be required under standby letters of credit. These risk participations covered $640 million of the $6,584 million standby letters of credit outstanding at December 31, 2006. At December 31, 2006, the carrying value of the Corporation’s standby and commercial letters of credit and financial guarantees, which is included in “accrued expenses and other liabilities” on the consolidated balance sheet, totaled $78 million.
 
Note 21 — Contingent Liabilities
 
Legal Proceedings
 
The Corporation and certain of its subsidiaries are subject to various pending and threatened legal proceedings arising out of the normal course of business or operations. In view of the inherent difficulty of predicting the outcome of such matters, the Corporation cannot state what the eventual outcome of these matters will be. However, based on current knowledge and after consultation with legal counsel, management believes that current reserves, determined in accordance with SFAS 5, “Accounting for Contingencies”, (SFAS 5) are adequate and the amount of any incremental liability arising from these matters is not expected to have a material adverse effect on the Corporation’s consolidated financial condition or results of operations.
 
Tax Contingency
 
In the ordinary course of business, the Corporation enters into certain transactions that have tax consequences. From time to time, the IRS questions and/or challenges the tax position taken by the Corporation with respect to those transactions. The Corporation engaged in certain types of structured leasing transactions and a series of loans to foreign borrowers that the IRS disallowed in its examination of the Corporation’s federal tax returns for the years 1996 through 2000. The Corporation has had ongoing discussion with the IRS related to the series of loans to foreign borrowers and adjusted tax and related interest reserves based on settlements discussed.
 
The Corporation believes that its tax returns were filed based upon applicable statutes, regulations and case law in effect at the time of the transactions. The Corporation intends to vigorously defend its positions taken in those returns in accordance with its view of the law controlling these activities. However, as noted above, the IRS examination team, an administrative authority or a court, if presented with the transactions, could disagree with the Corporation’s interpretation of the tax law. After evaluating the risks and opportunities, the best outcome may result in a settlement. The ultimate outcome for each position is not known.
 
Based on current knowledge and probability assessment of various potential outcomes, the Corporation believes that the current tax reserves, determined in accordance with SFAS 5, are adequate to cover the above

matters, and the amount of any incremental liability arising from these matters is not expected to have a material adverse effect on the Corporation’s consolidated financial condition or results of operations. Probabilities and outcomes are reviewed as events unfold, and adjustments to the reserves are made when necessary. In July 2006, the FASB issued FIN 48, new accounting guidance which will change the method for determining tax benefits that the Corporation can recognize in its financial statements. The Corporation will adopt the provisions of FIN 48 in the first quarter 2007. See Note 2 on page 77 for a further discussion of the adoption of FIN 48.
 
Note 22 — Variable Interest Entities (VIE’s)
 
The Corporation evaluates its interest in certain entities to determine if these entities meet the definition of a VIE, and whether the Corporation was the primary beneficiary and should consolidate the entity based on the variable interests it held. The following provides a summary of the VIE’s in which the Corporation has a significant interest.
 
The Corporation owns 100% of the common stock of two entities formed in 1997 and 2001 to issue trust preferred securities. These entities meet the definition of a VIE, but the Corporation is not the primary beneficiary in either of these entities. The trust preferred securities held by these entities ($405 million at December 31, 2006) are classified as subordinated debt. The Corporation is not exposed to loss related to these VIE’s. In December 2006, the Corporation gave irrevocable notice of its intention to call $55 million of the trust preferred securities on June 30, 2007. As such, the $55 million does not qualify as Tier 1 or Tier 2 capital. The remaining $350 million qualifies as Tier 1 capital.
 
The Corporation has a significant limited partnership interest in The Peninsula Fund Limited Partnership (PFLP), a venture capital fund, which was acquired in 1995. The PFLP’s general partner (an employee of the Corporation) is considered a related party to the Corporation. This entity meets the definition of a VIE, and the Corporation is the primary beneficiary of the entity. As such, the Corporation consolidates PFLP. Creditors of the partnership do not have recourse against the Corporation, and exposure to loss as a result of involvement with PFLP at December 31, 2006 was limited to approximately $1 million of book basis in the entity and approximately $2 million of commitments for future investments.
 
The Corporation has limited partnership interests in three other venture capital funds, which were acquired in 1998, 1999 and 2001, where the general partner (an employee of the Corporation) in these three partnerships is considered a related party to the Corporation. These three entities meet the definition of a VIE, however, the Corporation is not the primary beneficiary of the entities. As such, the Corporation accounts for its interest in these partnerships on the cost method. These three entities had approximately $190 million in assets at December 31, 2006. Exposure to loss as a result of involvement with these three entities at December 31, 2006 was limited to approximately $7 million of book basis of the Corporation’s investments and approximately $1 million of commitments for future investments.
 
The Corporation, as a limited partner, also holds an insignificant ownership percentage interest in 111 other venture capital and private equity investment partnerships where the Corporation is not related to the general partner. While these entities may meet the definition of a VIE, the Corporation is not the primary beneficiary of any of these entities as a result of its insignificant ownership percentage interest. The Corporation accounts for its interests in these partnerships on the cost method, and exposure to loss as a result of involvement with these entities at December 31, 2006 was limited to approximately $79 million of book basis of the Corporation’s investments and approximately $37 million of commitments for future investments.
 
Two limited liability subsidiaries of the Corporation are the general partners in two investment fund partnerships, formed in 1999 and 2003. As general partner, these subsidiaries manage the investments held by these funds. These two investment partnerships meet the definition of a VIE. In the investment fund partnership formed in 1999, the Corporation is not the primary beneficiary of the entity. As such, the Corporation accounts for its indirect interests in this partnership on the cost method. This investment partnership had approximately $198 million in assets at December 31, 2006 and was structured so that the Corporation’s exposure to loss as a result of its interest should be limited to the book basis of the Corporation’s investment in the limited liability

subsidiary, which was insignificant at December 31, 2006. In the investment fund partnership formed in 2003, the Corporation is the primary beneficiary of the entity and would be required to consolidate the entity, if material. This investment partnership had assets of approximately $10 million at December 31, 2006 and was structured so that the Corporation’s exposure to loss as a result of its interest should be limited to the book basis of the Corporation’s investment in the limited liability subsidiary, which was insignificant at December 31, 2006.
 
The Corporation has a significant limited partner interest in 21 low income housing tax credit/historic rehabilitation tax credit partnerships, acquired at various times from 1992 to 2006. These entities meet the definition of a VIE. However, the Corporation is not the primary beneficiary of the entities and, as such, accounts for its interest in these partnerships on the cost or equity method. These entities had approximately $150 million in assets at December 31, 2006. Exposure to loss as a result of its involvement with these entities at December 31, 2006 was limited to approximately $20 million of book basis of the Corporation’s investment, which includes unused commitments for future investments.
 
The Corporation, as a limited partner, also holds an insignificant ownership percentage interest in 95 other low income housing tax credit/historic rehabilitation tax credit partnerships. While these entities may meet the definition of a VIE, the Corporation is not the primary beneficiary of any of these entities as a result of its insignificant ownership percentage interest. As such, the Corporation accounts for its interest in these partnerships on the cost or equity method. Exposure to loss as a result of its involvement with these entities at December 31, 2006 was limited to approximately $286 million of book basis of the Corporation’s investment, which includes unused commitments for future investments.
 
For further information on the company’s consolidation policy, see Note 1 on page 70.
 
Note 23 — Estimated Fair Value of Financial Instruments
 
Disclosure of the estimated fair values of financial instruments, which differ from carrying values, often requires the use of estimates. In cases where quoted market values are not available, the Corporation uses present value techniques and other valuation methods to estimate the fair values of its financial instruments. These valuation methods require considerable judgment, and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used. Accordingly, the estimates provided herein do not necessarily indicate amounts which could be realized in a current exchange. Furthermore, as the Corporation typically holds the majority of its financial instruments until maturity, it does not expect to realize many of the estimated amounts disclosed. The disclosures also do not include estimated fair value amounts for items which are not defined as financial instruments, but which have significant value. These include such items as core deposit intangibles, the future earnings potential of significant customer relationships and the value of trust operations and other fee generating businesses. The Corporation believes the imprecision of an estimate could be significant.
 
The Corporation used the following methods and assumptions in estimating fair value disclosures for financial instruments:
 
Cash and due from banks, federal funds sold and securities purchased under agreements to resell, and interest-bearing deposits with banks:   The carrying amount approximates the estimated fair value of these instruments.
 
Trading securities:   These securities are carried at quoted market value or the market value for comparable securities, which represents estimated fair value.
 
Loans held-for-sale:   The market value of these loans represents estimated fair value or estimated net selling price. The market value is determined on the basis of existing forward commitments or the current market values of similar loans.
 
Investment securities:   Investment securities are carried at quoted market value, if available. The market value for comparable securities is used to estimate fair value if quoted market values are not available.
 
Domestic business loans:   These consist of commercial, real estate construction, commercial mortgage and equipment lease financing loans. The estimated fair value of the Corporation’s variable rate commercial loans is

Table of Contents

 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
Comerica Incorporated and Subsidiaries

represented by their carrying value, adjusted by an amount which estimates the change in fair value caused by changes in the credit quality of borrowers since the loans were originated. The estimated fair value of fixed rate commercial loans is calculated by discounting the contractual cash flows of the loans using year-end origination rates derived from the Treasury yield curve or other representative bases. The resulting amounts are adjusted to estimate the effect of changes in the credit quality of borrowers since the loans were originated.
 
International loans:   These consist primarily of short-term trade-related loans, variable rate loans or loans which have no cross-border risk due to the existence of domestic guarantors or liquid collateral. The estimated fair value of the Corporation’s international loan portfolio is represented by their carrying value, adjusted by an amount which estimates the effect on fair value of changes in the credit quality of borrowers or guarantors.
 
Retail loans:   This category consists of residential mortgage and consumer loans. The estimated fair value of residential mortgage loans is based on discounted contractual cash flows or market values of similar loans sold in conjunction with securitized transactions. For consumer loans, the estimated fair values are calculated by discounting the contractual cash flows of the loans using rates representative of year-end origination rates. The resulting amounts are adjusted to estimate the effect of changes in the credit quality of borrowers since the loans were originated.
 
Customers’ liability on acceptances outstanding and acceptances outstanding:   The carrying amount approximates the estimated fair value.
 
Loan servicing rights:   The estimated fair value is representative of a discounted cash flow analysis, using interest rates and prepayment speed assumptions currently quoted for comparable instruments.
 
Deposit liabilities:   The estimated fair value of demand deposits, consisting of checking, savings and certain money market deposit accounts, is represented by the amounts payable on demand. The carrying amount of deposits in foreign offices approximates their estimated fair value, while the estimated fair value of term deposits is calculated by discounting the scheduled cash flows using the year-end rates offered on these instruments.
 
Short-term borrowings:   The carrying amount of federal funds purchased, securities sold under agreements to repurchase and other borrowings approximates estimated fair value.
 
Medium- and long-term debt:   The estimated fair value of the Corporation’s variable rate medium- and long-term debt is represented by its carrying value. The estimated fair value of the fixed rate medium- and long-term debt is based on quoted market values. If quoted market values are not available, the estimated fair value is based on the market values of debt with similar characteristics.
 
Derivative instruments:   The estimated fair value of interest rate and energy commodity swaps represents the amount the Corporation would receive or pay to terminate or otherwise settle the contracts at the balance sheet date, taking into consideration current unrealized gains and losses on open contracts. The estimated fair value of foreign exchange futures and forward contracts and commitments to purchase or sell financial instruments is based on quoted market prices. The estimated fair value of interest rate, energy commodity and foreign currency options (including caps, floors and collars) is determined using option pricing models. The estimated fair value of warrants that are accounted for as derivatives are valued using a Black-Scholes valuation model. All derivative instruments are carried at fair value on the balance sheet.
 
Credit-related financial instruments:   The estimated fair value of unused commitments to extend credit and standby and commercial letters of credit is represented by the estimated cost to terminate or otherwise settle the obligations with the counterparties. This amount is approximated by the fees currently charged to enter into similar arrangements, considering the remaining terms of the agreements and any changes in the credit quality of counterparties since the agreements were entered into. This estimate of fair value does not take into account the significant value of the customer relationships and the future earnings potential involved in such arrangements as the Corporation does not believe that it would be practicable to estimate a representational fair value for these items.

Note 24 — Business Segment Information
 
The Corporation has strategically aligned its operations into three major business segments: the Business Bank, the Retail Bank (formerly known as Small Business & Personal Financial Services), and Wealth & Institutional Management. These business segments are differentiated based on the type of customer and the related products and services provided. In addition to the three major business segments, the Finance Division is also reported as a segment. Business segment results are produced by the Corporation’s internal management accounting system. This system measures financial results based on the internal business unit structure of the Corporation. Information presented is not necessarily comparable with similar information for any other financial institution. The management accounting system assigns balance sheet and income statement items to each business segment using certain methodologies, which are regularly reviewed and refined. For comparability purposes, amounts in all periods are based on business segments and methodologies in effect at December 31, 2006. These methodologies, which are briefly summarized in the following paragraph, may be modified as management accounting systems are enhanced and changes occur in the organizational structure or product lines.
 
The Corporation’s internal funds transfer pricing system records cost of funds or credit for funds using a combination of matched maturity funding for certain assets and liabilities and a blended rate based on various maturities for the remaining assets and liabilities. The allowance for loan losses is allocated to both large business and certain large personal purpose consumer and residential mortgage loans that have deteriorated below certain levels of credit risk based on a non-standard, specifically calculated amount. Additional loan loss reserves are allocated based on industry-specific risk not captured in the credit scores of individual loans. For other business loans, it is recorded in business units based on the credit score of each loan outstanding. For other consumer and residential mortgage loans, the allowance for loan losses is allocated based on applying projected loss ratios to various segments of the loan portfolio. The related loan loss provision is assigned based on the amount necessary to maintain an allowance for loan losses adequate for each product category. Noninterest income and expenses directly attributable to a line of business are assigned to that business segment. Direct expenses incurred by areas whose services support the overall Corporation are allocated to the business segments as follows: product processing expenditures are allocated based on standard unit costs applied to actual volume measurements; administrative expenses are allocated based on estimated time expended; and corporate overhead is assigned based on the ratio of a business segment’s noninterest expenses to total noninterest expenses incurred by all business segments. Equity is attributed based on credit, operational and interest rate risks. Most of the equity attributed relates to credit risk, which is determined based on the credit score and expected remaining life of each loan, letter of credit and unused commitment recorded in the business units. Operational risk is allocated based on deposit balances, non-earning assets, trust assets under management, and the nature and extent of expenses incurred by business units. Virtually all interest rate risk is assigned to Finance, as are the Corporation’s hedging activities.
 
The following discussion provides information about the activities of each business segment. A discussion of the financial results and the factors impacting 2006 performance can be found in the section entitled “Business Segments” in the financial review on page 33.
 
The Business Bank is primarily comprised of the following businesses: middle market, commercial real estate, national dealer services, global finance, large corporate, leasing, financial services, and technology and life sciences. This business segment meets the needs of medium-size businesses, multinational corporations and governmental entities by offering various products and services, including commercial loans and lines of credit, deposits, cash management, capital market products, international trade finance, letters of credit, foreign exchange management services and loan syndication services.
 
The Retail Bank includes small business banking (entities with annual sales under $10 million) and personal financial services, consisting of consumer lending, consumer deposit gathering and mortgage loan origination. In addition to a full range of financial services provided to small business customers, this business segment offers a variety of consumer products, including deposit accounts, installment loans, credit cards, student loans, home equity lines of credit, and residential mortgage loans.

Wealth & Institutional Management offers products and services consisting of personal trust, which is designed to meet the personal financial needs of affluent individuals (as defined by individual net income or wealth), private banking, institutional trust, retirement services, investment management and advisory services, investment banking, and discount securities brokerage services. This business segment also offers the sale of annuity products, as well as life, disability and long-term care insurance products.
 
The Finance segment includes the Corporation’s securities portfolio and asset and liability management activities. This segment is responsible for managing the Corporation’s funding, liquidity and capital needs, performing interest sensitivity analysis and executing various strategies to manage the Corporation’s exposure to liquidity, interest rate risk, and foreign exchange risk.
 
The Other category includes the discontinued operations of the Corporation’s Munder subsidiary (formerly included in the Wealth & Institutional Management segment), divested business lines, the income and expense impact of cash and loan loss reserves not assigned to specific business segments, tax benefits not assigned to specific business segments and miscellaneous other expenses of a corporate nature. The loan loss reserves represent the unallocated allowance for loan losses.

Note 26 — Sales of Businesses/Discontinued Operations
 
In December 2006, the Corporation sold its ownership interest in Munder to an investor group. Munder provides investment advisory services to institutions, municipalities, unions, charitable organizations and private investors, and also serves as investment advisor for Munder Funds. For its approximately 87 percent fully diluted interest in Munder, the Corporation received $232 million in cash at closing, an interest-bearing contingent note and Munder’s interest in World Asset Management, an internal division of Munder with $17 billion in indexed assets under management at December 31, 2006. The contingent note has an initial principal amount of $70 million, which would be realized if the Corporation’s client-related revenues earned by Munder remain consistent with current levels of approximately $17 million per year for the five years following the closing of the transaction (2007-2011). The principal amount of the note may be increased to a maximum of $80 million or decreased to as low as zero, depending on the level of such revenues earned in the five years following the closing.

Repayment of the principal is scheduled to begin after the sixth anniversary of the closing of the transaction from Munder’s excess cash flows, as defined in the sale agreement. The note matures in December 2013. Future gains related to the contingent note are expected to be recognized periodically as targets for the Corporation’s client-related revenues earned by Munder are achieved. The potential future gains are expected to be recorded between 2008 and the fourth quarter of 2011, unless fully earned prior to that time. The sale, including associated costs and assigned goodwill, resulted in a net after-tax gain of $108 million, or $0.67 per average annual diluted share. Included in “income from discontinued operations, net of tax” on the consolidated statement of income for the year ended December 31, 2006 were the following items related to the sale:
 
         
    (in millions)  
 
Sale proceeds, less net book value and costs to sell
  $ 181

As a result of the sale transaction, the Corporation accounted for Munder as a discontinued operation and all prior periods presented have been restated. As such, Munder was reported in “Other” and “Finance & Other” for business and geographic market segment reporting purposes, respectively. Munder was previously reported in “Wealth & Institutional Management” and “Midwest & Other Markets” for business and geographic market segment reporting purposes, respectively. Included in income from discontinued operations before income taxes was $11 million of intercompany noninterest income in each of the three years ended December 31, 2006, 2005 and 2004 and $1 million, $2 million and $1 million of intercompany noninterest expense in the years ended December 31, 2006, 2005 and 2004, respectively. The assets and liabilities related to the discontinued operations of Munder are not material and have not been reclassified on the consolidated balance sheets.

During the third quarter 2006, the Corporation completed the sale of its Mexican bank charter. Included in “net gain (loss) on sales of businesses” on the consolidated statements of income is a net loss on the sale of $12 million, which is reflected in the Corporation’s Business Bank business segment and Midwest & Other Markets geographic market segment. As part of the sale transaction, the Corporation transferred $24 million of loans and $18 million of liabilities to the buyer.
 
In the fourth quarter 2006, the Corporation decided to sell a portfolio of loans related to manufactured housing, located primarily in Michigan and Ohio. In accordance with SFAS 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” approximately $74 million of loans have been classified as held-for-sale, which are included in “other short-term investments” on the consolidated balance sheet at December 31, 2006. The Corporation recorded a $9 million charge-off to adjust the loans classified as held-for-sale to fair value.
 
During the fourth quarter 2005, HCM Holdings Limited (formerly Framlington Holdings Limited), which is a 49 percent owned subsidiary of Munder, sold its 90.8 percent interest in London, England based Framlington Group Limited. The sale resulted in a net after-tax gain of $32 million, or $0.19 per diluted share, which is included in “income from discontinued operations, net of tax” on the consolidated statements of income and reflected in “Other” and “Finance & Other” for business and geographic market segment reporting purposes, respectively.

REPORT OF MANAGEMENT
 
The management of Comerica Incorporated (the Corporation) is responsible for the accompanying consolidated financial statements and all other financial information in this Annual Report. The consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles and include amounts which of necessity are based on management’s best estimates and judgments and give due consideration to materiality. The other financial information herein is consistent with that in the consolidated financial statements.
 
In meeting its responsibility for the reliability of the consolidated financial statements, management develops and maintains effective internal controls, including those over financial reporting, as defined in the Securities and Exchange Act of 1934, as amended. The Corporation’s internal control over financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Corporation; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles, and that receipts and expenditures of the Corporation are made only in accordance with authorizations of management and directors of the Corporation; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Corporation’s assets that could have a material effect on the consolidated financial statements.
 
Management assessed, with participation of the Corporation’s Chief Executive Officer and Chief Financial Officer, internal control over financial reporting as it relates to the Corporation’s consolidated financial statements presented in conformity with U.S. generally accepted accounting principles as of December 31, 2006. The assessment was based on criteria for effective internal control over financial reporting described in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management determined that internal control over financial reporting is effective as it relates to the Corporation’s consolidated financial statements presented in conformity with U.S. generally accepted accounting principles as of December 31, 2006.
 
Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
 
The consolidated financial statements as of December 31, 2006 were audited by Ernst & Young LLP, an independent registered public accounting firm. The audit was conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), which required the independent public accountants to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement and whether effective internal control over financial reporting is maintained in all material respects. In addition, management’s assessment of the effectiveness of internal control over financial reporting as of December 31, 2006 was audited by Ernst & Young LLP, as stated in their report which is included herein.
 
The Corporation’s Board of Directors oversees management’s internal control over financial reporting and financial reporting responsibilities through its Audit Committee as well as various other committees. The Audit Committee, which consists of directors who are not officers or employees of the Corporation, meets regularly with management, internal audit and the independent public accountants to assure that the Audit Committee, management, internal auditors and the independent public accountants are carrying out their responsibilities, and to review auditing, internal control and financial reporting matters.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
Board of Directors and Shareholders
Comerica Incorporated
 
We have audited management’s assessment, included in the accompanying Report of Management, that Comerica Incorporated maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). The Corporation’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Corporation’s internal control over financial reporting based on our audit.
 
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Corporation; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of the Corporation are being made only in accordance with authorizations of management and directors of the Corporation; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Corporation’s assets that could have a material effect on the consolidated financial statements.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
 
In our opinion, management’s assessment that Comerica Incorporated maintained effective internal control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on the COSO criteria. Also, in our opinion, Comerica Incorporated maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on the COSO criteria.
 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Comerica Incorporated as of December 31, 2006 and 2005, and the related consolidated statements of income, changes in shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2006 and our report dated February 14, 2007 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
Board of Directors and Shareholders
Comerica Incorporated
 
We have audited the accompanying consolidated balance sheets of Comerica Incorporated and subsidiaries as of December 31, 2006 and 2005, and the related consolidated statements of income, changes in shareholders’ equity, and cash flows for each of the three years in the period ended December 31, 2006. These financial statements are the responsibility of the Corporation’s management. Our responsibility is to express an opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Comerica Incorporated and subsidiaries at December 31, 2006 and 2005, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2006, in conformity with U.S. generally accepted accounting principles.
 
As discussed in Note 16 to the consolidated financial statements, in 2006 Comerica Incorporated and subsidiaries changed its method of accounting for defined benefit pension and other postretirement plans.
 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of Comerica Incorporated’s internal control over financial reporting as of December 31, 2006, based on criteria established in “Internal Control-Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 14, 2007, expressed an unqualified opinion thereon.
