DETROIT, Oct. 19 /PRNewswire-FirstCall/ -- Comerica Incorporated (NYSE: CMA) today reported third quarter 2006 earnings of $200 million, or $1.23 per diluted share, compared to $200 million, or $1.22 per diluted share, for the second quarter 2006 and $238 million, or $1.41 per diluted share, for the third quarter 2005. The third quarter 2005 earnings included a $30 million negative provision for loan losses and the positive net pre-tax effect of a $14 million warrant accounting adjustment. During the third quarter 2006, Comerica announced it had reached a definitive agreement to sell its stake in Munder Capital Management (Munder). The transaction is expected to close by year-end, with an initial after-tax gain in the range of $100 million to $110 million. Effective third quarter 2006, Comerica is accounting for Munder as a discontinued operation, and all periods presented have been restated to reflect this change.

"Our third quarter results underscore many positive core operating trends, and reflect our emphasis on growth and balance," said Ralph W. Babb Jr., chairman and chief executive officer. "Loan growth in our fastest-growing markets continued at a double-digit pace and credit quality in all markets remained excellent. Net charge-offs were at an historically low level, while nonperforming assets increased slightly from the second quarter but remained at a low level."

  Third Quarter and Nine-Month 2006 Highlights

  Third Quarter 2006 Compared to Second Quarter 2006

* On an annualized basis, excluding Financial Services Division loans, average loans increased seven percent, with growth of 12 percent in the Western market, 24 percent in the Texas market and one percent in Midwest & Other Markets.

* The net interest margin was 3.79 percent in the third quarter 2006, a decrease of 3 basis points from 3.82 percent in the second quarter 2006.

* Total revenue decreased $7 million, or one percent. Excluding a mark- to-market loss on warrants of $5 million and an incremental loss on the sale of the Mexican bank charter of $7 million in the third quarter 2006, total revenue increased $5 million, or one percent.

* Net loan charge-offs as a percent of average total loans were 2 basis points for the third quarter of 2006, compared to 15 basis points for the second quarter of 2006, reflecting continued strong credit quality.

* Noninterest expenses, excluding the provision for credit losses on lending-related commitments, increased $15 million, or four percent, over the second quarter 2006, primarily due to salaries and employee benefits expense of $9 million and interest on tax liabilities of $8 million, largely reflecting a $6 million tax-related refund received in the second quarter.

* Open market share repurchases totaled 3.7 million shares, or two percent of total shares.

First Nine Months of 2006 Compared to First Nine Months of 2005

* Average loan growth was eight percent, excluding Financial Services Division loans, with 15 percent growth in the Western market, 18 percent growth in the Texas market and one percent growth in Midwest & Other Markets.

* Total revenue was unchanged while net interest income increased two percent. Total revenue increased $38 million, or two percent, excluding the 2006 loss on the sale of the Mexican bank charter of $12 million and the benefit of a warrant accounting change of $20 million in the third quarter 2005.

* Net loan charge-offs as a percent of average total loans were 11 basis points for the first nine months of 2006, down from 27 basis points in the same period in 2005. Nonperforming assets decreased 11 percent to $197 million at September 30, 2006, compared to $220 million at September 30, 2005.

* The provision for loan losses was $15 million for the first nine months of 2006, compared to a negative $27 million for the first nine months of 2005. The provision for credit losses on lending-related commitments was $9 million for the first nine months of 2006, compared to a negative $7 million for the first nine months of 2005.

* Noninterest expenses, excluding the provision for credit losses on lending-related commitments, increased $57 million, or five percent, largely due to interest on tax liabilities of $14 million, share-based compensation of $14 million and outside processing fees of $8 million.

  Net Interest Income and Net Interest Margin in Line with Full-Year Outlook

  Net interest income                   $502          $500          $512

  Net interest margin                   3.79 %        3.82 %        4.15 %

    Total loans                        48,125       47,802        44,582
      FSD loans (primarily low-rate)    2,093        2,557         2,334

    Total interest-bearing deposits    29,133       28,446        25,540

* Net interest income in the third quarter 2006 benefited from earning asset growth and one more day in the quarter, when compared to the second quarter 2006, and was partially offset by a decline in noninterest-bearing deposits and funding loan growth with non-core deposits and purchased funds.

* When compared to the second quarter 2006, the third quarter 2006 net interest margin reflected competitive loan and deposit pricing, the decline in noninterest-bearing deposits and loan growth in excess of deposit growth. This decrease was partially offset by the positive impact of lower average Financial Services Division loans (primarily low-rate) and a higher benefit from noninterest-bearing sources of funds in a rising rate environment.

* Third quarter 2005 reflected a change in accounting for warrants, which increased net interest income and net interest margin by $20 million and 16 basis points, respectively.

Noninterest Income Reflects Stable Trends in Fee Income

Noninterest income was $196 million for the third quarter 2006, compared to $205 million for the second quarter 2006 and $215 million for the third quarter 2005. The $9 million decrease in noninterest income in the third quarter 2006, compared to the second quarter 2006, reflected a $9 million decline in warrant income and a $7 million incremental loss recognized on the sale of the Mexican bank charter in the third quarter 2006, included in "net loss on sales of businesses" on the consolidated statements of income. This decrease was partially offset by higher income from venture capital investments of $5 million, and higher fee income from several sources such as service charges on deposit accounts, letter of credit fees and commercial lending fees. Certain categories of noninterest income are highlighted in the table below.

  Noninterest Expenses Remain Well Controlled

Noninterest expenses were $400 million for the third quarter 2006, compared to $391 million for the second quarter 2006 and $411 million for the third quarter 2005. The increase in noninterest expenses from the second quarter 2006 reflected increased salaries and employee benefits expense of $9 million and interest on tax liabilities of $8 million primarily reflecting a $6 million tax-related refund in the second quarter, partially offset by a decrease in the provision for credit losses on lending-related commitments of $6 million.

Certain categories of noninterest expenses are highlighted in the table below. Customer services expense varies from period-to-period due to changes in the level of noninterest-bearing deposits in the Financial Services Division, the earnings credit allowance provided on these deposits and a competitive environment.

  Munder Sale Expected to Close by Year-End

On August 4, 2006, Comerica announced it had reached a definitive agreement to sell its stake in Munder to an investor group. Completion of the closing, which is currently anticipated for late 2006, is subject to certain regulatory and third party approvals and the satisfaction of other customary conditions.

Comerica expects it will recognize an initial after-tax gain from the sale of Munder in the range of $100 million to $110 million upon closing. Effective with the third quarter 2006, Comerica is accounting for Munder as a discontinued operation, which means the after-tax earnings of Munder are reported as a single item at the bottom of the income statements. All periods presented have been restated to reflect this change.

Credit Quality Remained Excellent with Charge-offs at Historically Low Level

"Credit quality continues to be excellent, particularly in the West and Texas," said Babb. "Net credit-related charge-offs remained very low, at 6 basis points of average total loans. We are fully aware of the issues facing the automotive and real estate segments, and we believe we have reflected that awareness in our loss reserves."

During the third quarter 2006, $39 million of loans greater than $2 million were transferred to nonaccrual status, a decrease of $12 million from the second quarter 2006. The total provision for credit losses exceeded net credit-related charge-offs, reflecting trends in the automotive and real estate segments. While nonperforming assets increased by five basis points of total loans compared to the second quarter 2006, they remained at the low level of 42 basis points of total loans.

  Net interest margin                  3.41  %       3.48 %        4.17 %

* The net interest margin of 3.41 percent decreased seven basis points, primarily due to lower noninterest-bearing deposits in the Financial Services Division, a change in the deposit mix, and competitive loan pricing, partially offset by a decrease in Financial Services Division loans (primarily low- rate).

* Average loans increased $298 million, or three percent on an annualized basis. Excluding the Financial Services Division and the seasonably slow National Dealer Services business, average loans increased $952 million, or nine percent on an annualized basis, primarily due to growth in the Middle Market, Global Corporate Banking, and Commercial Real Estate businesses.

* Average deposits increased $252 million, excluding the $1.0 billion deposit decline in the Financial Services Division.

* The provision for loan losses declined $7 million, primarily due to lower net loan charge-offs.

* Noninterest income decreased $16 million, primarily due to a $9 million decline in warrant income and an incremental loss of $7 million on the sale of the Mexican bank charter.

* Noninterest expenses decreased $11 million, primarily due to a decrease in the provision for credit losses on lending-related commitments.

* Average loans and deposits were relatively unchanged.

* The provision for loan losses decreased $1 million, primarily due to lower net loan charge-offs.
