Fannie Mae Reports on Credit Quality

by Tanta on 8/16/2007 10:43:00 AM

There is a great deal of information in this Fannie Mae report on its outstanding mortgage book.

On Alt-A:

As of June 30, 2007, we have purchased or guaranteed approximately $310 billion of Alt-A loans, or 12 percent of our single-family mortgage credit book of business, where Alt-A loans are defined as loans that lenders, when delivering mortgage loans to us, have classified as Alt-A based on the reduced documentation requirements or other product features of these loans. We usually guarantee Alt-A loans from our traditional lenders that generally specialize in originating prime mortgage loans. Alt-A loans originated by these lenders typically follow an origination path similar to that used for their prime origination process. In addition, Alt-A loans we guaranty must comply with our guidelines and the terms of our seller-servicer agreements. Accordingly, we believe that our guaranteed Alt-A loans have more favorable credit characteristics than the overall market of Alt-A loans, based on the following data for Alt-A loans in our single-family mortgage credit book of business (as of June 30, 2007):
• Average loan amount is $172,545.
• Adjustable rate loans represent 33% of the book.
• High FICO scores – 720 weighted average; 1 percent has a FICO score of less than 620.
• Approximately 39 percent of the loans have credit enhancement.
• Low exposure to loans with high LTV ratios – 5 percent of our Alt-A loans have original LTV ratios greater than 90 percent.
• Estimated weighted average mark-to-market LTV is 64 percent.
• Approximately 1.01 percent of the Alt-A book is seriously delinquent.
• Guaranty fees on Alt-A loans are generally higher than our average guaranty fee to compensate us for the increased risk associated with this product. Our Alt-A loans are currently performing consistent with expectations used in establishing our guaranty pricing.
On total book:
We believe our conventional single-family mortgage credit book has characteristics that reflect our historically disciplined approach to risk management. Our book is highly diversified based on date of origination, geography and product type. Some salient data (as of June 30, 2007) include:
• Total conventional single-family mortgage credit book of business is $2,338 billion.
• Average loan amount is $138,736.
• Geographically diverse, with no region representing greater than 25% of the single-family mortgage credit book of business.
• Approximately 0.64 percent of the book is seriously delinquent.
• Weighted average original loan-to-value (LTV) ratio is 71 percent, with 9 percent above 90 percent.
• Estimated weighted average mark-to-market LTV ratio is 57 percent, with 4 percent above 90 percent. Less than 1 percent of our book has a mark-to-market LTV ratio greater than 100 percent. Mark-to-market LTV reflects changes in the value of the property and amortization of the principal balance subsequent to origination.
• Weighted average FICO score of borrowers is 722, with 5 percent below 620 FICO score.
• Fixed rate loans total 88 percent of the book; adjustable rate loans total 12 percent.
• Loans to owner-occupants make up 90 percent of our book; the balance is investor and second home properties.
• Second lien mortgages are 0.1 percent of the book.
• Credit enhancement exists on 20 percent of the book.
