"We saw many encouraging and positive signs in the fourth quarter," said Ralph W. Babb Jr., chairman and chief executive officer. "Period-end loan outstandings were stable, with commercial loans up more than $700 million, or about three percent. We were pleased to see growth in loan outstandings across multiple business lines, particularly Middle Market loans in Texas, as well as growth in National Dealer Services, Mortgage Banker Finance, Energy Lending, and Technology and Life Sciences. These increases were muted by the planned and continued reduction of loans in our Commercial Real Estate business line. We also saw broad-based improvement in credit quality, strong deposit growth and fee income generation. Continued balance sheet strength through careful management of liquidity and capital has positioned Comerica for growth as the economic environment improves.

"Our customers are conveying a more positive and confident tone. Generally, they are feeling much better about the economy. Throughout our geographic footprint, our relationship managers report a growing sense of optimism among customers and prospects. This can be seen in our strong loan pipeline. Given the many positive signs we have seen, as well as our strategy for success, which is focused on growth and balance, we believe we are uniquely positioned for the future."

Fourth Quarter and Full-Year 2010 Overview

Fourth Quarter 2010 Highlights Compared to Third Quarter 2010

    --  Credit quality improvement accelerated in the fourth quarter 2010.  Net
        credit-related charge-offs decreased $19 million to $113 million.
        Internal watch list loans declined $629 million to $5.5 billion. 
        Nonaccrual loans decreased $83 million and loans past due 90 days or
        more declined $42 million.  As a result, the provision for loan losses
        decreased $65 million to $57 million.
    --  Period-end total loan outstandings were stable, with growth in
        commercial loans of $713 million muted by runoff in the Commercial Real
        Estate business line.  Average loans increased $229 million in the
        fourth quarter 2010, excluding a decrease of $332 million in the
        Commercial Real Estate business line.  In total, average loans decreased
        $103 million, compared to declines of $570 million and $641 million in
        the third and second quarters of 2010, respectively.
    --  Average core deposits increased $1.1 billion in the fourth quarter 2010,
        reflecting increases in noninterest-bearing deposits and money market
        and NOW deposits, partially offset by a decrease in customer
        certificates of deposit.  Average core deposits increased across all
        markets and in most business lines.
    --  Total revenue increased five percent in the fourth quarter 2010, driven
        by an increase in noninterest income of $29 million, reflecting
        increases in numerous fee categories.
    --  The net interest margin of 3.29 percent increased six basis points.
        Average earning assets decreased $1.1 billion in the fourth quarter
        2010, compared to the third quarter 2010, primarily due to a $1.2
        billion decrease in excess liquidity, to $1.8 billion in the fourth
        quarter 2010.
    --  Noninterest expenses totaled $437 million in the fourth quarter 2010, an
        increase of $35 million from the third quarter 2010, in part the result
        of an increase in salaries expense of $18 million. The increase in
        salaries expense was largely driven by an increase in incentive
        compensation, reflecting improved overall performance and final 2010
        peer rankings, and an increase in deferred compensation plan costs,
        which was offset by an increase in deferred compensation asset returns
        in noninterest income.
    --  In October 2010, Comerica redeemed $515 million of 6.576% subordinated
        notes due 2037 at par and recognized a pre-tax charge of $5 million in
        noninterest expenses resulting from the accelerated accretion of the
        original issuance discount. The notes related to trust preferred
        securities issued by an unconsolidated subsidiary, which were
        concurrently redeemed.
    --  Capital ratios remained strong. The tangible common equity ratio
        increased 15 basis points to 10.54 percent at December 31, 2010 and the
        estimated Tier 1 ratio increased 12 basis points, to 10.08 percent at
        December 31, 2010, from September 30, 2010.
    --  In the fourth quarter 2010, Comerica doubled the quarterly dividend to
        10 cents per share, authorized the repurchase of up to 12.6 million
        shares of common stock in the open market and authorized the purchase of
        outstanding warrants to purchase up to 11.5 million shares of common
        stock.

Full-Year 2010 Compared to Full-Year 2009

    --  Credit quality improved significantly.  Net credit-related charge-offs
        decreased $305 million to $564 million. Internal watch list loans
        declined $2.2 billion to $5.5 billion. Nonaccrual loans decreased $85
        million and loans past due 90 days or more declined $39 million.  As a
        result, the provision for loan losses decreased $602 million to $480
        million.
    --  Average earning assets were $51.0 billion in 2010, a decrease of $7.2
        billion from 2009. Average loans decreased $5.6 billion in 2010 to $40.5
        billion, reflecting subdued loan demand from customers in a modestly
        recovering economic environment.
    --  Average core deposits increased $3.4 billion to $38.7 billion, primarily
        reflecting increases of $3.4 billion in money market and NOW deposits
        and $2.2 billion in noninterest-bearing deposits, partially offset by a
        $2.3 billion decrease in customer certificates of deposit.

Full-Year 2010 Compared to Full-Year 2009 (continued)

    --  The net interest margin was 3.24 percent for 2010, compared to 2.72
        percent for 2009.  The increase in the net interest margin was primarily
        due to changes in the funding mix, including a continued shift in
        funding sources toward lower-cost funds, and improved loan spreads.
    --  Noninterest income decreased $261 million compared to 2009.  Increases
        in commercial lending fees ($16 million), card fees ($7 million) and
        letter of credit fees ($7 million) were partially offset by decreases in
        service charges on deposit accounts ($20 million) and fiduciary income
        ($7 million). Additionally, 2009 included net securities gains ($243
        million), gains related to the repurchase of debt ($15 million) and net
        gains on the termination of leveraged leases ($8 million).
    --  Noninterest expenses decreased $10 million, compared to 2009, primarily
        reflecting decreases in FDIC insurance expense ($28 million), pension
        expense ($27 million) and other real estate expense ($19 million),
        partially offset by an increase in salaries expense ($53 million).  The
        increase in salaries expense was largely driven by an increase in
        incentive compensation, reflecting improved overall performance and
        final 2010 peer rankings. Full-time equivalent staff decreased by
        approximately 330 employees, or four percent, from December 31, 2009.
    --  In March 2010, Comerica fully redeemed $2.25 billion of preferred stock
        issued to the U.S. Treasury.  The redemption was funded by the net
        proceeds from an $880 million common stock offering also completed in
        March 2010 and from excess liquidity at the parent company.  The
        redemption resulted in a one-time charge of $94 million, included in
        preferred stock dividends, reflecting the accelerated accretion of the
        remaining discount. In addition, in October 2010, Comerica redeemed $515
        million of subordinated notes related to trust preferred securities.

    (b) Core deposits exclude other time deposits and foreign office time
    deposits.

    --  Net interest income was stable, as the impact of a decline in average
        earning assets was offset by an increase in the net interest margin.
    --  Average earning assets decreased $1.1 billion, primarily due to a
        decrease of $1.2 billion in excess liquidity, represented by average
        Federal Reserve Bank deposits. Excluding a decrease of $332 million  in
        the Commercial Real Estate business line, average loans increased $229
        million in the fourth quarter 2010, including increases across all
        markets in the National Dealer Services, Mortgage Banker Finance and
        Energy Lending business lines.  Additionally, average loans increased in
        the Middle Market business line in the Texas market.
    --  The net interest margin of 3.29 percent increased six basis points
        compared to third quarter 2010.  The increase in the net interest margin
        reflected the benefit from the decrease in excess liquidity and the
        redemption of higher-cost trust preferred securities discussed above,
        partially offset by a decrease in yields on investment securities,
        primarily resulting from elevated prepayment activity in
        higher-yielding, mortgage-backed investment securities.
    --  Fourth quarter 2010 average core deposits increased $1.1 billion
        compared to third quarter 2010, reflecting increases of $687 million in
        noninterest-bearing deposits and $621 million in money market and NOW
        deposits, partially offset by a decrease of $206 million in customer
        certificates of deposit.   Average core deposits increased across all
        markets and in most business lines.

Noninterest Income

Noninterest income was $215 million for the fourth quarter 2010, compared to $186 million for the third quarter 2010. The $29 million increase resulted largely from increases in commercial lending fees ($7 million), deferred compensation asset returns ($6 million), bank-owned life insurance ($5 million), customer derivative income ($4 million), and a $4 million insurance recovery in the fourth quarter 2010, as well as smaller increases across several fee categories. As expected, service charges on deposit accounts declined $2 million, largely the result of the impact of Regulation E on overdraft fees.

Noninterest Expenses

Noninterest expenses were $437 million for the fourth quarter 2010, compared to $402 million for the third quarter 2010. The $35 million increase in noninterest expenses was primarily due to an increase in salaries expense ($18 million), a $5 million one-time charge related to the redemption of subordinated notes previously discussed, and increases in outside processing fees ($4 million) and litigation and operational losses ($4 million). The increase in salaries expense was primarily due to increases in executive and business unit incentives ($10 million), deferred compensation plan costs ($6 million) (offset by an increase in deferred compensation asset returns in noninterest income) and severance expense ($3 million), partially offset by a decrease in share-based compensation expense ($5 million). Full-time equivalent staff decreased by approximately 330 employees, or four percent, from December 31, 2009.

Credit Quality

"All of the key credit metrics are moving in the right direction, with decreases in net charge-offs, watch list loans and nonaccrual loans, all leading to a significant decline in the provision for loan losses," said Babb. "Comerica's credit performance throughout this cycle has been among the best in our peer group. We believe it is a reflection of our strong credit culture and the diligent credit quality review processes we employ. We expect to see continued improvement given the moderate pace of the economic recovery."

    --  Net credit-related charge-offs decreased $19 million to $113 million in
        the fourth quarter 2010, from $132 million in the third quarter 2010.
        The decrease in net credit-related charge-offs primarily resulted from
        decreases of $19 million in the Commercial Real Estate business line and
        $9 million in the Middle Market business line, partially offset by
        increases of $6 million in the Global Corporate Banking business line
        and $4 million in Private Banking.
    --  Internal watch list loans declined $629 million to $5.5 billion from
        September 30, 2010 to December 31, 2010.
    --  During the fourth quarter 2010, $180 million of loan relationships
        greater than $2 million were transferred to nonaccrual status, a
        decrease of $114 million from the third quarter 2010, primarily due to a
        $61 million decrease in transfers from the Commercial Real Estate
        business line and a $54 million decrease in transfers from the Middle
        Market business line.  Of the transfers of loan relationships greater
        than $2 million to nonaccrual in the fourth quarter 2010, $71 million
        were from the Commercial Real Estate business line, primarily in the
        Midwest and Florida markets, and $71 million were from the Middle Market
        business line, in the Midwest and Western markets.
    --  Nonperforming assets decreased $76 million to $1.2 billion, or 3.06
        percent of total loans and foreclosed property, at December 31, 2010.
    --  Nonaccrual loans were charged down 46 percent at December 31, 2010.
    --  Foreclosed property decreased $8 million to $112 million at December 31,
        2010, from $120 million at September 30, 2010.
    --  Loans past due 90 days or more and still accruing were $62 million at
        December 31, 2010, a decrease of $42 million compared to September 30,
        2010.
    --  The provision for loan losses decreased $65 million, primarily due to
        reductions in the Middle Market, Private Banking, Commercial Real Estate
        and Leasing business lines, partially offset by increases in the Global
        Corporate Banking and Personal Banking business lines.
    --  The allowance for loan losses to total loans ratio was 2.24 percent and
        2.38 percent at December 31, 2010 and September 30, 2010, respectively.

Balance Sheet and Capital Management

Total assets and common shareholders' equity were $53.7 billion and $5.8 billion, respectively, at December 31, 2010, compared to $55.0 billion and $5.9 billion, respectively, at September 30, 2010. There were approximately 177 million common shares outstanding at December 31, 2010.

Comerica's tangible common equity ratio was 10.54 percent at December 31, 2010, an increase of 15 basis points from September 30, 2010. The estimated Tier 1 ratio increased 12 basis points, to 10.08 percent at December 31, 2010, from September 30, 2010.

Full-Year 2011 Outlook

For full-year 2011, management expects the following, compared to full-year 2010, based on a continuation of modest growth in the economy. NOTE: This outlook does not include any impact from the acquisition of Sterling Bancshares, Inc.

    --  A low single-digit decrease in average loans.  Excluding the Commercial
        Real Estate business line, a low single-digit increase in average loans.
    --  Average earning assets of approximately $48 billion, reflecting lower
        excess liquidity in addition to a decrease in average loans.
    --  An average net interest margin similar to full-year 2010, based on no
        increase in the Federal Funds rate.
    --  Net credit-related charge-offs between $350 million and $400 million.
        The provision for credit losses is expected to be between $150 million
        and $200 million.
    --  A low single-digit decline in noninterest income, primarily due to the
        impact of regulatory changes.
    --  A low single-digit increase in noninterest expenses, primarily due to an
        increase in employee benefits expense.
    --  Income tax expense to approximate 36 percent of income before income
        taxes less approximately $60 million of permanent differences related to
        low-income housing and bank-owned life insurance.
    --  Commence a share repurchase program that, combined with dividend
        payments, results in a payout of less than 50 percent of earnings.

    (a) Excess liquidity, represented by average balances deposited with
    the Federal Reserve Bank, reduced the net interest margin by 20
    basis points and 11 basis points in 2010 and 2009, respectively.
    Excluding excess liquidity, the net interest margin would have been
    3.44% in 2010 and 2.83% in 2009.  See Reconciliation of Non-GAAP

    (a) Excess liquidity, represented by average balances deposited with
    the Federal Reserve Bank, reduced the net interest margin by 12
    basis points and 19 basis points in the fourth and third quarters of
    2010, respectively, and by 13 basis points in the fourth quarter of
    2009.  Excluding excess liquidity, the net interest margin would
    have been 3.41%, 3.42% and 3.07% in each respective period.  See

    (a) Excess liquidity represented by interest earned on and average
    balances deposited with the Federal Reserve Bank (FRB).

    The net interest margin (FTE), excluding excess liquidity, removes
    interest earned on balances deposited with the FRB from net interest
    income (FTE) and average balances deposited with the FRB from
    average earning assets from the numerator and denominator of the net
    interest margin (FTE) ratio, respectively. Comerica believes this
    measurement provides meaningful information to investors,
    regulators, management and others of the impact on net interest
    income and net interest margin resulting from Comerica's short-term
    investment in low yielding instruments.

    (a) Tier 1 capital and risk-weighted assets as defined by regulation.
    (b) December 31, 2010 Tier 1 capital and risk-weighted assets are
    estimated.

    The Tier 1 common capital ratio removes preferred stock and
    qualifying trust preferred securities from Tier 1 capital as defined
    by and calculated in conformity with bank regulations.  The tangible
    common equity removes preferred stock and the effect of intangible
    assets from capital and the effect of intangible assets from total
    assets.  Comerica believes these measurements are meaningful
    measures of capital adequacy used by investors, regulators,
    management and others to evaluate the adequacy of common equity and
    to compare against other companies in the industry.
