AIG breaks into mortgage securitization big-time with high quality first offering 

When American International Group sold its mortgage-guaranty unit United Guaranty to Arch Capital Group last year, the company said that it planned to turn to residential mortgages to make up for the loss in revenue from the sale of United Guaranty. But AIG didn’t start originating new loans. Rather, the company has been buying up high-quality jumbo mortgages, and now plans to securitize those loans.
