|FEDERAL NATIONAL MORTGAGE ASSOCIATION FANNIE MAE filed this Form 10-Q on 05/06/2011|
Family and Multifamily businesses work with our lender customers, who deliver mortgage loans that we purchase and securitize into Fannie Mae MBS. Our Capital Markets group manages our investment activity in mortgage-related assets, funding investments primarily through proceeds we receive from the issuance of debt securities in the domestic and international capital markets. The Capital Markets group also works with lender customers to provide funds to the mortgage market through short-term financing and other activities, making short-term use of our balance sheet. These financing activities include whole loan conduit transactions, early funding transactions, Real Estate Mortgage Investment Conduit (REMIC) and other structured securitization activities, and dollar rolls, which we describe in more detail in our 2010 Form 10-K in BusinessBusiness SegmentsCapital Markets Group.
In the first quarter of 2011, we purchased or guaranteed approximately $189 billion in loans, measured by unpaid principal balance, which includes approximately $20 billion in delinquent loans we purchased from our single-family MBS trusts. Excluding delinquent loans purchased from our MBS trusts, our purchases and guarantees enabled our lender customers to finance approximately 759,000 single-family conventional loans and multifamily loans secured by multifamily properties with approximately 83,000 units.
We remained the largest single issuer of mortgage-related securities in the secondary market, with an estimated market share of new single-family mortgage-related securities issuances of 48.6% during the first quarter of 2011. In comparison, our estimated market share of new single-family mortgage-related securities issuances was 49.0% in the fourth quarter of 2010 and 40.8% in the first quarter of 2010. If the Federal Housing Administration (FHA) continues to be the lower-cost option for some consumers, and in some cases the only option, for loans with higher loan-to-value (LTV) ratios, our market share could be adversely impacted if the market shifts away from refinance activity, which is likely to occur when interest rates rise. We remain a constant source of liquidity in the multifamily market. Currently, we own or guarantee approximately one-fifth of the outstanding debt on multifamily properties.
Building a Strong New Single-Family Book of Business
Our new single-family book of business has a strong overall credit profile and is performing well. In this section, we discuss our expectations for these loans and their performance to date.
Expected Profitability of Our Single-Family Acquisitions
While it is too early to know how loans in our new single-family book of business will ultimately perform, given their strong credit risk profile, low levels of payment delinquencies shortly after acquisition, and low serious delinquency rates, we expect that, over their lifetime, these loans will be profitable. Table 1 provides information about whether we expect loans we acquired in 1991 through the first quarter of 2011 to be profitable, and the percentage of our single-family guaranty book of business represented by these loans as of March 31, 2011. The expectations reflected in Table 1 are based on the credit risk profile of the loans we have acquired, which we discuss in more detail in Table 3: Credit Profile of Single-Family Conventional Loans Acquired and in Table 34: Risk Characteristics of Single-Family Conventional Business Volume and Guaranty Book of Business. These expectations are also based on numerous other assumptions, including our expectations regarding home price declines set forth below in Outlook. As shown in Table 1, we expect loans we have acquired in 2009, 2010 and the first quarter of 2011 to be profitable. If future macroeconomic conditions turn out to be significantly more adverse than our expectations, these loans could become unprofitable. For example, we believe that these loans would become unprofitable if home prices declined more than 15% from their March 2011 levels over the next five years based on our home price index, which would be an approximately 34% decline from their peak in the third quarter of 2006.
