"We intend to focus on asset selection and the relative value of various sectors within the mortgage market," the firm's regulatory filing said. "We believe that the residential mortgage market will undergo dramatic changes in the coming years as the role of (government-sponsored entities) such as Fannie Mae and Freddie Mac, is diminished, which we expect will create attractive investment opportunities for us." It notes that risks of investing in the IPO include, among others, the risks associated with changes in prepayment rates, interest rates  and the economy. Write to Kerry Curry.
