"We were pleased to see total loan growth of $1.5 billion, or 4 percent, on a period-end basis," said Ralph W. Babb Jr., chairman and chief executive officer. "The growth was driven by a $1.9 billion, or 8 percent, increase in commercial loans, particularly in National Dealer Services, Mortgage Banker Finance, Energy Lending, Technology and Life Sciences, and Global Corporate Banking.

"We had record deposit levels of $47.8 billion at year-end, an increase of $303 million from the third quarter. In addition, our net interest income increased $21 million, or 5 percent, primarily driven by an increase in average earning assets. We continue to be pleased by the broad-based improvement in credit quality, which resulted in a decrease in the provision for loan losses."

"With respect to our acquisition of Sterling, we announced the successful completion of systems integrations and the opening of former Sterling branches as Comerica banking centers on November 14, 2011," said Babb. "All former Sterling customers can now bank at any Comerica banking center, with complete access to our full line of extended product and service offerings. This acquisition continues to be a great fit, as the former Sterling's size, geographic footprint and customer focus uniquely fits our strategy and expands our presence in Texas.

"In the fourth quarter, we repurchased 1.6 million shares, and repurchased a total of 4.1 million shares in 2011 under the share repurchase program. Combined with dividends, this resulted in a total return to shareholders of 47 percent of net income. We continue to be an active capital manager and believe we are approaching capital management from a position of strength. As required, we submitted our Capital Plan to the Federal Reserve on January 9, 2012. As previously announced, we are targeting a first quarter 2012 total payout ratio of up to 50 percent of net income through the share repurchase program and dividends."

Fourth Quarter and Full-Year 2011 Overview

Fourth Quarter 2011 Highlights Compared to Third Quarter 2011


    --  Period-end total loans increased $1.5 billion, or 4 percent, from
        September 30, 2011 to December 31, 2011, primarily reflecting an
        increase of $1.9 billion, or 8 percent, in commercial loans, partially
        offset by a decrease of $390 million in commercial real estate loans
        (commercial mortgage and real estate construction loans).  The increase
        in commercial loans was primarily driven by increases in National Dealer
        Services, Mortgage Banker Finance, Energy Lending, Technology and Life
        Sciences, and Global Corporate Banking.  Average total loans increased
        $1.4 billion, or 3 percent, in the fourth quarter, in part due to one
        additional month of Sterling.
    --  Period-end deposits increased $303 million, or one percent, primarily
        reflecting an increase of $648 million in noninterest-bearing deposits,
        partially offset by decreases in savings ($247 million) and customer
        certificates of deposit ($172 million). Average total deposits increased
        $2.7 billion, in part due to one additional month of Sterling in the
        fourth quarter.
    --  Net interest income of $444 million increased $21 million, or 5 percent,
        compared to the third quarter, primarily resulting from an increase in
        average earning assets of $2.4 billion.
    --  Credit quality continued to improve in the fourth quarter 2011. Net
        credit-related charge-offs decreased $17 million to $60 million.  The
        provision for loan losses decreased to $19 million in the fourth quarter
        2011, compared to $38 million in the third quarter 2011.
    --  Noninterest income decreased $19 million to $182 million in the fourth
        quarter 2011, compared to $201 million for the third quarter 2011,
        primarily due to a $16 million decrease in net securities gains
        (losses), reflecting a net loss of $4 million in the fourth quarter 2011
        compared to a net gain of $12 million in the third quarter 2011.
    --  Noninterest expenses increased $18 million to $478 million in the fourth
        quarter 2011, compared to $460 million in the third quarter 2011,
        primarily due to increases in severance and related expenses ($5
        million) and merger and restructuring charges ($4 million), as well as
        one additional month of Sterling expenses (approximately $8 million).

Full-Year 2011 Highlights Compared to Full-Year 2010


    --  Net income of $393 million for 2011 increased $116 million, or 42
        percent, compared to 2010.
    --  Period-end total loans increased $2.4 billion, or 6 percent, from
        year-end 2010 to year-end 2011, reflecting the acquisition of Sterling
        and primarily including a net increase of $2.9 billion, or 13 percent,
        in commercial loans, partially offset by a net decrease of $223 million
        in commercial real estate loans.  The increase in commercial loans was
        primarily driven by increases in Mortgage Banker Finance, Energy Lending
        and Technology and Life Sciences, as well as increases in Middle Market
        and Global Corporate Banking.  Average loans declined $442 million in
        2011.
    --  Period-end deposits increased $7.3 billion, or 18 percent, in part due
        to the acquisition of Sterling. Average total deposits increased $4.3
        billion.
    --  Net interest income increased $7 million in 2011, compared to 2010, as
        the benefit provided by accretion of the purchase discount on the
        acquired Sterling loan portfolio in 2011 and an increase in average
        earning assets of $1.1 billion was largely offset by decreased yields on
        mortgage-backed investment securities and a decrease in business loan
        swap income.
    --  Credit quality improved significantly.  The provision for loan losses
        declined $327 million to $153 million in 2011, compared to 2010.  Net
        credit-related charge-offs decreased $236 million to $328 million.
    --  Noninterest income increased $3 million compared to 2010.
    --  Noninterest expenses increased $122 million compared to 2010.  2011
        included Sterling-related merger and restructuring charges of $75
        million ($47 million, after-tax; $0.25 per diluted share) and five
        months of Sterling expenses.
    --  Repurchases of 4.1 million shares in 2011, combined with dividends,
        returned 47 percent of 2011 net income to shareholders.

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


    --  The $21 million increase in net interest income in the fourth quarter
        2011, when compared to the third quarter 2011, resulted primarily from
        an increase in average earning assets of $2.4 billion, partially offset
        by decreasing yields on mortgage-backed investment securities and a
        decrease in the accretion of the purchase discount on the acquired
        Sterling loan portfolio.  Decreasing yields on the mortgage-backed
        investment securities portfolio reflected the impact of lower yields on
        securities purchased to reinvest prepayments.  Accretion of the purchase
        discount was $26 million in the fourth quarter 2011, compared to $27
        million in the third quarter.
    --  Average earning assets increased $2.4 billion in the fourth quarter
        2011, compared to the third quarter 2011, reflecting increases of $1.6
        billion in average investment securities available-for-sale and $1.4
        billion in average loans, partially offset by a $584 million decrease in
        average Federal Reserve Bank deposits. The increase in average loans
        included one additional month of Sterling in the fourth quarter and
        primarily reflected increases in commercial loans in Mortgage Banker
        Finance, Energy Lending, National Dealer Services, and Technology and
        Life Sciences.
    --  Average deposits increased $2.7 billion in the fourth quarter 2011,
        compared to the third quarter 2011, in part due to one additional month
        of Sterling. Average noninterest-bearing deposits increased $1.7 billion
        and average money market and NOW deposits increased $1.1 billion.

Noninterest Income

Noninterest income was $182 million for the fourth quarter 2011, compared to $201 million for the third quarter 2011. The $19 million decrease was primarily due to decreases in net securities gains (losses) ($16 million) and card fees ($6 million), due primarily to the implementation of regulatory limits on debit card transaction processing fees, partially offset by an increase in deferred compensation asset returns ($5 million) (offset by an increase in deferred compensation plan costs in noninterest expenses). Net securities gains (losses) in the third quarter 2011 reflected net gains of $12 million due primarily to the repositioning of the acquired Sterling investment securities portfolio, compared to a net loss of $4 million in the fourth quarter 2011 that resulted primarily from a $5 million charge related to a derivative contract tied to the conversion rate of Visa Class B shares.

Noninterest Expenses

Noninterest expenses totaled $478 million in the fourth quarter 2011, an increase of $18 million compared to $460 million in the third quarter 2011. The increase was primarily due to increases in deferred compensation plan costs ($5 million) (offset by an increase in deferred compensation asset returns in noninterest income), severance and related expenses ($5 million) and merger and restructuring charges ($4 million), as well as one additional month of Sterling expenses (approximately $8 million).

Credit Quality

"We continued to see steady improvement in credit trends in the fourth quarter," said Babb. "This was the 10th consecutive quarter of decline in net charge-offs, with a $17 million decrease. The decline in net charge-offs was larger than expected, primarily the result of higher recoveries in the quarter. Other credit metrics were in line with expectations. Nonperforming assets were under $1 billion for the first time since the fourth quarter of 2008. The former Sterling loan portfolio has performed as expected. As a result of the overall improvements in credit quality, the provision for loan losses declined to $19 million."

    --  Net credit-related charge-offs decreased $17 million to $60 million in
        the fourth quarter 2011, from $77 million in the third quarter 2011. The
        decrease in net credit-related charge-offs primarily reflected decreases
        in Small Business Banking ($12 million), Middle Market ($11 million) and
        Commercial Real Estate ($7 million), partially offset by an increase in
        Technology and Life Sciences ($10 million).
    --  Internal watch list loans declined $502 million in the fourth quarter
        2011, to $4.5 billion at December 31, 2011, and nonperforming assets
        decreased $64 million.
    --  During the fourth quarter 2011, $99 million of borrower relationships
        greater than $2 million were transferred to nonaccrual status, a
        decrease of $31 million from the third quarter 2011.  Of the transfers
        of borrower relationships greater than $2 million to nonaccrual in the
        fourth quarter 2011, $27 million were from Commercial Real Estate, $24
        million were from Private Banking and $21 million were from Global
        Corporate Banking.
    --  Nonperforming loans decreased $71 million, compared to September 30,
        2011, to $887 million, or 2.08 percent of total loans, at December 31,
        2011.

Balance Sheet and Capital Management

Total assets and common shareholders' equity were $61.0 billion and $6.9 billion, respectively, at December 31, 2011, compared to $60.9 billion and $7.0 billion, respectively, at September 30, 2011. There were approximately 197 million common shares outstanding at December 31, 2011. Comerica repurchased 1.6 million and 4.1 million shares of common stock in the open market in the fourth quarter and full-year 2011, respectively, under the share repurchase program.

    --  Net interest income increasing moderately.
    --  Net credit-related charge-offs declining and a relatively stable
        provision for credit losses.
    --  Noninterest income relatively stable.
    --  Noninterest expenses relatively stable.

    (a) Tier 1 capital and risk-weighted assets as defined by regulation.
    (b) December 31, 2011 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.
