M&I Retains Strong Capital Position

MILWAUKEE, Dec. 17 /PRNewswire-FirstCall/ — Marshall & Ilsley Corporation (NYSE:MI) (M&I) today announced several unusual events which will impact M&I’s financial results for the quarter and year ending December 31, 2007.

On November 1, 2007, the separation of Metavante Technologies, Inc. from M&I was completed resulting in a gain to M&I of $526 million. This gain is tax-free to M&I and will be reported as a component of discontinued operations in the quarter ending December 31, 2007. There will also be after-tax costs of approximately $21 million related to the separation transaction in the same period. M&I received a contribution of $1.665 billion in cash in the separation transaction which strengthened M&I’s capital position as described below.

On November 13, 2007, M&I announced that it would record an after-tax liability of approximately $5 million in connection with its share of the proposed settlement of the American Express antitrust litigation against Visa. While M&I is not a named defendant in this litigation, M&I and other Visa member banks are obligated to share in certain losses in connection with the litigation under Visa’s by-laws.

On November 16, 2007, M&I completed the sale of its three branches in the Tulsa, Oklahoma market resulting in an after-tax gain of approximately $17 million. M&I determined that exiting the Tulsa market was a better allocation of resources as compared to the costs of further expansion in that market.

On December 17, 2007, M&I retired $1 billion of Puttable Reset Securities (“PURS”) issued by its subsidiary, M&I Marshall & Ilsley Bank. The PURS were initially issued in November 2000, and were remarketed in December of each year thereafter. Given the currently unfavorable credit market environment, M&I determined to retire the PURS in order to lower M&I’s borrowing costs going forward. M&I incurred a one-time, after-tax charge of $48 million in connection with the retirement of this debt. M&I expects to recover this charge through lower financing costs over the next approximately three years.

Finally, as was discussed in M&I’s third quarter Form 10-Q, M&I continues to assess its loan portfolio, particularly as the real estate segment continues to deteriorate. M&I expects that charge-offs in the fourth quarter may be up to $195 million and the loan loss provision in the fourth quarter may be up to $235 million. At November 30, 2007, M&I had a consolidated tangible capital ratio of approximately 9.6 percent.

“Despite these challenging market conditions, we are fortunate to have one of the strongest capital positions in the industry,” said Mark Furlong, president and CEO, Marshall & Ilsley Corporation. “We believe we are well positioned to weather the downturn in the real estate market.”
