"In this sluggish and still uncertain economic environment, our customers have remained understandably cautious. This is reflected in the weak loan demand and continued strong core deposit levels," said Ralph W. Babb Jr., chairman and chief executive officer. "Our solid capital and liquidity position enabled us to fully redeem our trust preferred securities on October 1, which will reduce interest expense. This uniquely positions us as the only bank in our peer group to have redeemed TARP and eliminated trust preferred securities.

"Our third quarter financial results reflected the continued improvement in credit quality and careful control of expenses. Our skill-based, relationship-driven strategy and our prudent, conservative approach to banking continued to serve us well."

Third Quarter 2010 Highlights Compared to Second Quarter 2010

    --  Credit quality continued to improve.  Net credit-related charge-offs
        decreased $14 million to $132 million and the provision for credit
        losses, which includes both the provision for loan losses and the
        provision for credit losses on lending-related commitments, decreased
        $10 million to $116 million. Watch list loans - generally consistent
        with regulatory defined special mention, substandard and doubtful
        (nonaccrual) loans - declined $480 million to $6.2 billion.
    --  The pace of decline in loans continued to slow in the third quarter
        2010.  Average loans decreased $570 million, compared to declines of
        $641 million and $1.4 billion in the second and first quarters of 2010,
        respectively.  About one-half of the third quarter 2010 decrease in
        average loans was in the Commercial Real Estate business line. Average
        loans increased in the third quarter 2010 in the Mortgage Banker
        Finance, National Dealer Services and Energy Lending business lines.
    --  Average deposit levels remained strong in the third quarter 2010,
        decreasing only one percent from the second quarter 2010.  Growth in
        business deposits was offset by reduced Personal and Private Banking
        deposits.
    --  Net interest income decreased $18 million to $404 million for the third
        quarter 2010, compared to $422 million for the second quarter 2010.
        Average earning assets decreased $1.6 billion in the third quarter 2010,
        compared to the second quarter 2010, and the net interest margin of 3.23
        percent decreased five basis points, from 3.28 percent in the second
        quarter 2010.
    --  Expenses remained well controlled in the third quarter 2010. 
        Noninterest expenses increased one percent from second quarter 2010 to
        third quarter 2010.  Full-time equivalent staff decreased by
        approximately 300 employees, or three percent, from September 30, 2009.
    --  Capital ratios remained strong. The tangible common equity ratio
        increased 28 basis points to 10.39 percent at September 30, 2010 and the
        estimated Tier 1 common ratio increased 16 basis points, to 9.97 percent
        at September 30, 2010, from June 30, 2010.  The estimated Tier 1 capital
        ratio was 9.97 percent at September 30, 2010, compared to 10.64 percent
        at June 30, 2010, reflecting the redemption of trust preferred
        securities.

Net Interest Income and Net Interest Margin

    Selected average balances:

    (a) See Reconciliation of Non-GAAP Financial Measures.
    (b) Core deposits exclude other time deposits and foreign office time
    deposits.

    --  The $18 million decrease in net interest income in the third quarter
        2010, when compared to second quarter 2010, resulted primarily from
        decreases in earning assets and the net interest margin.
    --  Average earning assets decreased $1.6 billion, including decreases of
        $736 million in average Federal Reserve Bank deposits, $570 million in
        average loans and $356 million in average investment securities. The
        decrease in average loans reflected decreases in the Middle Market,
        Commercial Real Estate and Global Corporate Banking business lines,
        partially offset by increases in the Mortgage Banker Finance, National
        Dealer Services and Energy Lending business lines.
    --  The net interest margin of 3.23 percent decreased five basis points,
        compared to second quarter 2010.  The third quarter 2010 was negatively
        impacted by a reduction in deferred loan fees recognized, compared to
        the second quarter 2010, resulting from a higher rate of loan
        prepayments in the first half of 2010, and accelerated prepayments on
        higher-yielding mortgage-backed investment securities in the third
        quarter 2010.  A reduction in excess liquidity partially offset these
        decreases. The net interest margin was reduced by approximately 19 and
        23 basis points in the third and second quarters of 2010, respectively,
        from excess liquidity, which was represented by $3.0 billion of average
        balances deposited with the Federal Reserve Bank in the third quarter
        2010, compared to $3.7 billion of average balances in the second quarter
        2010.
    --  Third quarter 2010 average core deposits decreased $142 million compared
        to second quarter 2010.

Noninterest Income

Noninterest income was $186 million for the third quarter 2010, compared to $194 million for the second quarter 2010. The $8 million decrease resulted primarily from decreases of $6 million in customer derivative income (included in "other noninterest income") and $2 million in foreign exchange income, partially offset by a $3 million increase in investment banking income (included in "other noninterest income").

Noninterest Expenses

Noninterest expenses were $402 million for the third quarter 2010, compared to $397 million for the second quarter 2010. The $5 million increase in noninterest expenses in the third quarter 2010, compared to the second quarter 2010, was primarily due to increases in salaries expense ($8 million) and employee benefits expense ($2 million), partially offset by a decrease in the provision for credit losses on lending-related commitments ($6 million). The increase in salaries expense reflected the impact of one additional day in the third quarter 2010 and included an increase in share-based compensation expense of $6 million as a result of third quarter 2010 stock grants. Full-time equivalent staff decreased by approximately 300 employees, or three percent, from September 30, 2009.

Credit Quality

"The continued improvement in credit quality is reflected by the decline in net charge-offs for the fifth consecutive quarter, as well as the $10 million decline in the provision for credit losses compared to the second quarter," Babb said. "The increase in inflows to nonaccrual loans primarily reflected commercial real estate, which we believe will continue to exhibit variability with a downward trend. Overall, credit migration has actually improved, as evidenced by the $480 million decline in the watch list, which is our best early indicator of future credit quality. Our early recognition of credit issues and our ability to quickly and proactively work through them remains one of our key strengths."

    --  Net credit-related charge-offs decreased $14 million to $132 million in
        the third quarter 2010, from $146 million in the second quarter 2010.
        The decrease in net credit-related charge-offs resulted primarily from a
        $39 million decrease in the Middle Market business line in the third
        quarter 2010, partially offset by a $24 million increase in the
        Commercial Real Estate business line, primarily in the Western and
        Midwest markets.
    --  Watch list loans declined $480 million to $6.2 billion from June 30,
        2010 to September 30, 2010.
    --  The provision for credit losses decreased $10 million, primarily due to
        declines in the Middle Market,  Energy Lending and Entertainment Lending
        business lines, partially offset by increases in the Private Banking and
        Commercial Real Estate business lines.
    --  During the third quarter 2010, $294 million of loan relationships
        greater than $2 million were transferred to nonaccrual status, an
        increase of $95 million from the second quarter 2010, primarily due to a
        $100 million increase in transfers from the Commercial Real Estate
        business line.  Of the transfers of loan relationships greater than $2
        million to nonaccrual in the third quarter 2010, $132 million were from
        the Commercial Real Estate business line, primarily in the Western and
        Florida markets, $91 million were from the Middle Market business line,
        primarily in the Midwest market, and $28 million were from Energy
        Lending in the Texas market.
    --  Nonperforming assets increased $97 million to $1.3 billion, or 3.24
        percent of total loans and foreclosed property, at September 30, 2010.
    --  Nonaccrual loans were charged down 45 percent as of both September 30,
        2010 and June 30, 2010, compared to 41 percent one year ago.
    --  Foreclosed property increased $27 million to $120 million at September
        30, 2010, from $93 million at June 30, 2010.
    --  Loans past due 90 days or more and still accruing were $104 million at
        September 30, 2010, a decrease of $11 million compared to June 30, 2010.
    --  The allowance for loan losses to total loans ratio was 2.38 percent at
        both September 30, 2010 and June 30, 2010.

Balance Sheet and Capital Management

Total assets and common shareholders' equity were $55.0 billion and $5.9 billion, respectively, at September 30, 2010, compared to $55.9 billion and $5.8 billion, respectively, at June 30, 2010. There were approximately 176 million common shares outstanding at September 30, 2010.

On October 1, 2010 Comerica fully redeemed $500 million of trust preferred securities. Subsequent to the redemption, no additional trust preferred securities remained outstanding. As previously announced, Comerica will recognize a one-time, pre-tax charge of approximately $5 million in the fourth quarter 2010, reflecting accelerated accretion of the remaining trust preferred original issuance discount. The $500 million of trust preferred securities outstanding at September 30, 2010 were excluded from Tier 1 and total capital in the computation of estimated risk-based capital ratios as of September 30, 2010.

Comerica's tangible common equity ratio was 10.39 percent at September 30, 2010, an increase of 28 basis points from June 30, 2010. The estimated Tier 1 common ratio increased 16 basis points, to 9.97 percent at September 30, 2010, from June 30, 2010. The estimated Tier 1 capital ratio was 9.97 percent at September 30, 2010, compared to 10.64 percent at June 30, 2010. The decrease in the Tier 1 capital ratio reflected the redemption of the trust preferred securities, which accounted for 83 basis points in the June 30, 2010 Tier 1 capital ratio.

Fourth Quarter 2010 Outlook

For the fourth quarter 2010, management expects:

    --  Average earning assets of approximately $48 billion in the fourth
        quarter 2010, largely reflecting a decline in average excess liquidity
        from $3.0 billion in the third quarter 2010 to approximately $1 billion
        in the fourth quarter 2010. Excess liquidity is expected to decline
        primarily due to debt maturities and the redemption of the trust
        preferred securities.
    --  An average net interest margin between 3.30 percent and 3.35 percent
        primarily based on a decline in excess liquidity.
    --  Fourth quarter 2010 net credit-related charge-offs similar to third
        quarter 2010. The provision for credit losses is expected to be below
        net credit-related charge-offs.
    --  A low single-digit decline in noninterest income compared to the third
        quarter 2010.  Market-related fees are expected to be lower as customers
        remain cautious in a sluggish and still uncertain economic environment.
    --  A low single-digit increase in noninterest expenses compared to the
        third quarter 2010.  Included in the outlook is an estimated $5 million
        negative impact reflecting accelerated accretion of the remaining
        original issuance discount on the redemption of trust preferred
        securities.

    --  Average loans decreased $413 million, reflecting declines in all major
        markets. The decrease in average loans reflected decreases in Commercial
        Real Estate, Middle Market and Global Corporate Banking, partially
        offset by increases in Mortgage Banker Finance, National Dealer Services
        and Energy Lending. The decline in loans continued to slow in the third
        quarter 2010.
    --  Average deposits increased $197 million, primarily due to increases in
        Middle Market, Energy Lending and the Financial Services Division,
        partially offset by a decline in Global Corporate Banking.
    --  The net interest margin of 4.45 percent decreased 18 basis points, due
        in part to a reduction in deferred loan fees recognized in the third
        quarter 2010 and a change in the deposit mix, as balances moved from
        lower-cost transaction accounts to higher-cost money market accounts.
    --  The provision for loan losses decreased $26 million, primarily due to a
        decrease in Middle Market.
    --  Noninterest income decreased $9 million, primarily due to decreases in
        foreign exchange income and customer derivative income.
    --  Noninterest expenses decreased $2 million, primarily due to a decrease
        in the provision for credit losses on lending-related commitments,
        partially offset by an increase in allocated corporate overhead
        expenses.

    ------------------------------                          ----


    (a) Excess liquidity, represented by average balances deposited with
    the Federal Reserve Bank, reduced the net interest margin by 22
    basis points and 10 basis points year-to-date in 2010 and 2009,
    respectively.  Excluding excess liquidity, the net interest margin
    would have been 3.45% in 2010  and 2.75% in 2009.  See

    (a) Excess liquidity, represented by average balances deposited with
    the Federal Reserve Bank, reduced the net interest margin by 19
    basis points and 23 basis points in the third and second quarters of
    2010, respectively, and by 16 basis points in the third quarter of
    2009.  Excluding excess liquidity, the net interest margin would
    have been 3.42%, 3.51% and 2.84% 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) September 30, 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.
