AIG mulls spinning off mortgage insurance: Report

Ice Crack Split

American International Group is considering spinning off or selling its mortgage insurance segment amid shareholder pressure to split, The Wall Street Journal reported Thursday, citing sources.

The insurance giant's directors have discussed plans for the business for "a while" but have not made a final decision, according to the report. The unit, which sells coverage protecting mortgage lenders and investors, accounted for only about 5 percent of AIG's pretax profit in the second quarter.

AIG has recently received pressure from key shareholders such as Carl Icahn and John Paulson to break up the company and reduce regulatory risks. Icahn, an activist investor, said this week he took a "large stake" in AIG, calling the company "too big to succeed."
