Paul Miller of FBR Capital Markets has come up with similar estimates, though he sees an outside chance losses could turn out to be many multiples of that . Spokesmen for Bank of America and MBIA declined to comment. Bank of America shares were up 1.6% to $8.26 early Thursday afternoon following an agreement between the nation's five largest mortgage servicers, including Bank of America, Citigroup ( C), Wells Fargo ( WFC), JPMorgan Chase ( JPM) and Ally Financial with 49 attorneys general and the Obama Administration. As part of the deal, the banks will pay $25 billion to resolve mortgage servicing issues such as "robosigning," an attempt by banks to speed up the foreclosure crisis by cutting corners. -- Written by Dan Freed in New York.
