Ginnie Mae's additional disclosure data on Federal Housing Authority (FHA) single-family pools has shown just slight prepayment variances in characteristics that generally change the convexity profiles of specified pools.
Ginnie has begun to offer original LTD, loan purpose and property type on all fixed-rate single-family MBS. These are aside from disclosing WAC, WALA, geographical distribution, etc. The agency will also provide additional information on issuer details, origination year and geographic distribution for new issue pools. However, the added information will not be available for recently issued hybrid pools.
