“The second quarter results reflect the difficult economic environment, particularly the residential real estate development challenges,” said Ralph W. Babb Jr., chairman and chief executive officer. “We are managing through this environment by quickly identifying problem loans, building our loan loss reserve credit-by-credit, and strengthening our already solid capital position.

“While there are some signs the economy may be bottoming, businesses and individuals are still feeling the effects of this prolonged recession. They remain cautious in an environment in which unemployment rates have continued to rise.

COMERICA REPORTS SECOND QUARTER 2009 RESULTS

“Like the industry as a whole, we continue to see weak loan demand across our geographic markets. This mirrors the sharp slowdown in commercial and industrial loan growth that was evident in all 10 post-World War II recessions.

“We were pleased to see continued strong growth in average core deposits in the second quarter and, as expected, expansion of the net interest margin.  We remain focused on our customers and vigilant in controlling our expenses.

“Our capital ratios increased from already strong levels, as evidenced by a tangible common equity ratio of 7.55 percent.”

Second Quarter 2009 Compared to First Quarter 2009

·Average earning assets decreased $2.2 billion, reflecting a $1.9 billion decrease in average loans and a $340 million decrease in investment securities, which resulted from the sale of mortgage-backed government agency securities and the redemption of auction-rate securities.

·Average loans declined in all markets and nearly all business lines. The declines reflected reduced demand from customers in a contracting economic environment.

·Average core deposits, excluding the Financial Services Division, increased $1.1 billion in the second quarter 2009, reflecting a $1.0 billion increase in noninterest-bearing deposits.

·The net interest margin of 2.73 percent increased 20 basis points, from 2.53 percent in the first quarter 2009, primarily reflecting increasing loan spreads and maturities of higher-cost time deposits.

·Net credit-related charge-offs were $248 million, or 2.08 percent of average total loans, for the second quarter 2009, compared to $157 million, or 1.26 percent of average total loans, for the first quarter 2009, with the increases concentrated primarily in Leasing and Middle Market Banking in the Midwest and residential real estate development in Florida and Other markets.  Net credit-related charge-offs in the Texas and Western markets were stable. The provision for loan losses was $312 million for the second quarter 2009, compared to $203 million for the first quarter 2009, and the period-end allowance to total loans ratio increased to 1.89 percent from 1.68 percent at March 31, 2009.

·Noninterest income increased $75 million, primarily the result of a $100 million increase in net securities gains (substantially from sales of mortgage-backed government agency securities) and a $13 million increase in deferred compensation asset returns (offset by an increase in deferred compensation plan costs in noninterest expenses), partially offset by a decline resulting from a $16 million second quarter 2009 loss on the termination of leveraged leases compared to a $24 million first quarter 2009 gain on the termination of leveraged leases.

·Noninterest expenses increased $32 million from the first quarter, primarily due to a $30 million increase in FDIC insurance expense, reflecting an industry-wide FDIC special assessment charge in the second quarter 2009, and a $13 million increase in deferred compensation plan costs, partially offset by decreases in discretionary expenses and workforce. Excluding the FDIC special assessment charge, annualized noninterest expenses remain nearly 10 percent below noninterest expenses for the full-year 2008.

·The provision for income taxes decreased $58 million from the first quarter, primarily due to a change in the method of determining interim period (quarterly) federal taxes.  The second quarter 2009 provision for income taxes also was reduced by approximately $8 million in net adjustments including settlements related to federal and state tax audits.

·The estimated Tier 1 common ratio was 7.65 percent and the estimated Tier 1 capital ratio was 11.57 percent at June 30, 2009, increases of 33 basis points and 51 basis points, respectively, from March 31, 2009.

Total noninterest-bearing deposits, excluding FSD	11,132			10,095			8,825

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

·The $18 million increase in net interest income in the second quarter 2009, when compared to first quarter 2009, resulted primarily from an increase in the net interest margin and the impact of one more day ($4 million), partially offset by a decline in earning assets (primarily loans).

·Second quarter 2009 average core deposits, excluding the Financial Services Division, increased $1.1 billion compared to first quarter 2009, reflecting a $1.0 billion increase in noninterest-bearing deposits. The increase in noninterest-bearing deposits occurred across all business segments and from both commercial and consumer customers.

·The net interest margin of 2.73 percent increased 20 basis points, compared to first quarter 2009, primarily reflecting increasing loan spreads and maturities of higher-cost time deposits. The net interest margin was reduced by approximately eight basis points in each of the first two quarters of 2009 from excess liquidity, which was represented by $1.8 billion of average balances deposited with the Federal Reserve Bank. Excess liquidity resulted from strong deposit growth and security sales at a time when loan demand remained weak.

·Total average Financial Services Division noninterest-bearing deposits increased $145 million from the first quarter 2009. This division serves title and escrow companies that facilitate residential mortgage transactions and benefits from customer deposits related to mortgage escrow balances. Noninterest-bearing deposits increased primarily due to increased mortgage activity.

Noninterest Income

Noninterest income was $298 million for the second quarter 2009, compared to $223 million for the first quarter 2009 and $242 million for the second quarter 2008. Noninterest income in the second quarter 2009 included $113 million of net securities gains, primarily from gains from sales of mortgage-backed government agency securities ($109 million) and from redemptions of auction-rate securities ($3 million), compared to net securities gains of $13 million in the first quarter 2009.  Securities were sold based on Comerica’s expectation that mortgage rates will rise over time (i.e., securities prices will decline) and, with interest rates near zero, there is no longer a need to hold a large portfolio of fixed rate securities to mitigate the impact of potential future rate declines on net interest income. Noninterest income in the second quarter 2009 also reflected a $6 million gain on the sale of Comerica’s proprietary defined contribution plan recordkeeping business.  Deferred compensation asset returns were $8 million in the second quarter 2009, an increase of $13 million when compared to the first quarter 2009 (offset by an increase in deferred compensation plan costs in noninterest expenses). The second quarter 2009 included a $16 million loss on the termination of leveraged leases compared to a $24 million first quarter 2009 gain on the termination of leveraged leases (both the loss and the gain are included in “other noninterest income”). Selected categories of noninterest income are highlighted in the following table.

Noninterest Expenses

Noninterest expenses were $429 million for the second quarter 2009, compared to $397 million for the first quarter 2009 and $423 million for the second quarter 2008. The $32 million increase in noninterest expenses in the second quarter 2009, compared to the first quarter 2009, reflected a $30 million increase in FDIC insurance expense, resulting from an industry-wide FDIC special assessment charge in the second quarter 2009, and a $13 million increase in deferred compensation plan costs.  Regular salaries decreased $5 million, impacted by reductions in full-time equivalent staff of approximately 200 and 490 in the second quarter 2009 and first quarter 2009, respectively.  Certain categories of noninterest expenses are highlighted in the table below.

Tax-related items

The provision for income taxes in the second quarter 2009 decreased $58 million, when compared to the first quarter 2009, primarily due to a change in the method used to determine interim period (quarterly) federal taxes.  Beginning in the second quarter 2009, Comerica calculated income taxes discretely based on actual year-to-date 2009 pre-tax results.  In the first quarter 2009 and prior periods, Comerica calculated taxes by applying an estimated annual effective tax rate to year-to-date pre-tax results.  The change in method resulted in an approximately $20 million decrease in the income tax provision in the second quarter 2009.  If the same methodology had been applied in the first quarter, the income tax provision recorded in the first quarter 2009 would have been approximately $20 million lower. The decrease in the provision for income taxes in the second quarter 2009 also reflected approximately $8 million of net adjustments including settlements related to federal and state tax audits.

COMERICA REPORTS SECOND QUARTER 2009 RESULTS

Credit Quality

“The key credit issue for us remains in our Commercial Real Estate line of business, predominantly residential real estate development,” said Babb.  “We have seen signs of stabilization in the residential real estate portfolio in California.  Texas has held up relatively well, and we have been working through issues related to falling home prices in Michigan for several years. Florida had performed well for us, but the prolonged recession has recently taken a toll on our residential real estate development portfolio in that state, as well as in other markets.

“We are managing these problem loans effectively.  We are conducting in-depth reviews, obtaining current independent appraisals, taking the appropriate charge-offs and providing incremental reserves to reflect the challenges of this difficult economic environment.

“With regard to the automotive industry, we have anticipated and planned for the restructuring now underway, and no longer have any direct exposure to Chrysler or General Motors.  Our top-tier, mega-franchise auto dealer strategy continues to work well for us.  We have maintained excellent credit quality within our auto dealer portfolio, with no nonaccruals or charge-offs in the second quarter.  We have no material exposure to dealers which are closing.

“Within our automotive supplier portfolio, which we have continued to reduce, many of our customers who supply General Motors or Chrysler have been named essential suppliers by those automakers, and are expected to continue to operate.  Excluding a $21 million charge-off related to a General Motors leveraged lease, net auto-related charge-offs in the second quarter remained at a low level.”

·The allowance to total loans ratio increased to 1.89 percent at June 30, 2009, from 1.68 percent at March 31, 2009 and 1.28 percent at June 30, 2008.

·The provision for loan losses increased in the Midwest, Texas, Florida and Other markets. The provision in the Western market, which was relatively unchanged, benefited from a decline in Commercial Real Estate.

·Net credit-related charge-offs in the Commercial Real Estate business line in the second quarter 2009 were $108 million, of which $34 million were from residential real estate developers in the Western market. Comparable numbers for the first quarter 2009 were $74 million in total, of which $47 million were from residential real estate developers in the Western market. Commercial Real Estate net credit-related charge-offs were stable in the Midwest and Texas markets, and increased in Florida and Other markets.

·Net credit-related charge-offs excluding the Commercial Real Estate business line were $140 million in the second quarter 2009, or 1.35 percent of average non-Commercial Real Estate loans, compared to $83 million, or 76 basis points, in the first quarter 2009.  The $57 million increase in non-Commercial Real Estate net credit-related charge-offs, when compared to the first quarter 2009, was primarily due to increases in Specialty Businesses ($21 million), reflecting a $21 million charge-off related to a General Motors leveraged lease, Middle Market ($21 million), and Global Corporate ($13 million). Small Business and Private Banking were stable.

·Nonperforming assets increased to 2.64 percent of total loans and foreclosed property at June 30, 2009. During the second quarter 2009, $419 million of loan relationships greater than $2 million were transferred to nonaccrual status, an increase of $178 million from the first quarter 2009.  Of the transfers of loan relationships greater than $2 million to nonaccrual in the second quarter 2009, $204 million were in the Commercial Real Estate business line, $79 million were in Middle Market and $78 million were in Global Corporate.

·Nonaccrual loans were charged down 39 percent as of June 30, 2009, compared to 36 percent as of March 31, 2009 and 28 percent one year ago.

Balance Sheet and Capital Management

Total assets and common shareholders’ equity were $63.6 billion and $5.0 billion, respectively, at June 30, 2009, compared to $67.4 billion and $5.0 billion, respectively, at March 31, 2009. There were approximately 151 million common shares outstanding at June 30, 2009.

Comerica’s tangible common equity ratio was 7.55 percent at June 30, 2009. The second quarter 2009 estimated Tier 1 common, Tier 1 and total risk-based capital ratios were 7.65 percent, 11.57 percent and 15.96 percent, respectively.

2009 Outlook

·Management continues to focus on developing new and expanding existing customer relationships.  Management expects subdued loan demand in light of a domestic economy that is expected to continue contracting in the near term.

·Management expects the net interest margin to benefit from improved loan pricing and maturities of higher-cost wholesale funding.  Excess liquidity is expected to offset those benefits for the near-term, with the third quarter 2009 net interest margin expected to be relatively unchanged from the second quarter. Excess liquidity is expected to diminish during the fourth quarter from maturities of wholesale funding, resulting in net interest margin expansion. The target federal funds and short-term LIBOR rates are expected to remain flat for the remainder of 2009.

·Based on no significant further deterioration of the economic environment, management expects net credit-related charge-offs in the third quarter 2009 to be similar to second quarter 2009 and to improve modestly in the fourth quarter 2009. The provision for credit losses is expected to continue to exceed net charge-offs.

·Management expects additional securities gains from the sale of mortgage-backed government agency securities.

·Management expects a mid- to high-single digit decrease in full-year 2009 noninterest expenses, compared to full-year 2008, due to control of discretionary expenses and workforce.

·Noninterest income decreased $35 million.  The second quarter 2009 included a $16 million loss on the termination of leveraged leases compared to a $24 million first quarter 2009 gain on the termination of leveraged leases.

·Noninterest expenses decreased $8 million as an increase in FDIC insurance expense, due to the special assessment charge, was more than offset by a decrease in the provision for credit losses on lending-related commitments and nominal decreases in numerous discretionary expense categories.
