After two years of write-downs, credit quality is stabilizing at Milwaukee's Marshall & Ilsley Corporation, clearing a path for the $58 billion holding company to return to profitability. That was the message President and CEO Mark Furlong delivered in a 40-minute presentation March 10 at an investor conference hosted by Citi Financial Services in New York. Marshall & Ilsley Corporation is Wisconsin's largest banking organization, with its flagship, M&I Marshall and Ilsley Bank of Milwaukee, accounting for $50.2 billion of the corporation's assets. Three other charters are in St. Louis, Las Vegas and Mayville, Wis. The corporation's earnings peaked in 2007 when it sold its Metavante Technologies subsidiary. The sale contributed $526 million to the company's $1.1 billion in 2007 net income; since then, however, the earnings picture has been bleak. The company reported a loss of $2 billion in 2008 and a loss of $858 million in 2009.
