Mortgage Credit Book of Business
Table 33 displays the composition of our entire mortgage credit book of business as of the periods indicated. Our total single-family mortgage credit book of business accounted for 93% of our total mortgage credit book of business as of both March 31, 2011 and December 31, 2010.
The total mortgage credit book of business is not impacted by our repurchase of delinquent loans as this activity is a reclassification from loans of consolidated trusts to loans of Fannie Mae.
