Mortgage insurers such as Radian Group (RDN), MGIC Investment Corp (MTG), Genworth Financial (GNW) and Old Republic (ORI) sold billions of dollars of policies at low prices during the housing boom and were stuck with huge losses when the market crashed.

The recovery in the industry has been slower than investors had hoped.

Radian set aside $306.9 million to cover mortgage losses in the fourth quarter, up 79 percent from the preceding quarter. Provisions were down 8 percent compared to a year earlier.
