On April 30, Fannie Mae released loan performance data on a portion of its single-family mortgage loans, which includes a subset of Fannie Mae’s 30-year, fully amortizing, full documentation, single-family, conventional fixed-rate mortgages. The initial population is comprised of loans acquired between January 1, 2000 and March 31, 2012 with corresponding monthly performance data as of December 31, 2012. The loan performance data is divided into two files for each acquisition quarter: (i) the “Acquisition file” includes static data at the time of a mortgage loan’s origination and delivery to Fannie Mae; and (ii) the “Performance” file contains monthly performance data of each mortgage loan from the time of Fannie Mae’s acquisition up until its current status as of the previous quarter, until the mortgage loan has been liquidated, or until it has become 180 days or more delinquent. Fannie Mae expects to update the acquisitions data each quarter to include a new quarter of acquired mortgage loans as of the prior year in addition to updated performance data as of the previous quarter. Certain data attributes also will be updated to reflect new terms, if applicable, as a result of a modification.
