"The Detroit regional economy did not get a significant lift from the unusually mild weather that prevailed for much of December," according to Dana Johnson, Chief Economist at Comerica Bank. "Looking ahead, the local economy will continue to lag the nation in 2007. The direct and indirect impact of the restructuring of the domestic auto industry is creating a heavy drag on production, employment, and income in the metro area."

Comerica Incorporated (NYSE: CMA) is a financial services company headquartered in Detroit, strategically aligned by three business segments: The Business Bank, The Retail Bank, and Wealth & Institutional Management.
