FANNIE MAE
MONTHLY SUMMARY

APRIL 2006

HIGHLIGHTS FOR APRIL INCLUDE:

•	The gross mortgage portfolio grew at a 15.7 percent compound annualized rate in April. This growth reflects the Capital Markets group’s opportunistic approach to mortgage investment, and does not signal any significant change in the spread environment.
•	As previously announced, on May 23, 2006, Fannie Mae entered into an agreement with its regulator, OFHEO, not to increase its “mortgage portfolio” assets above the amount shown in its December 31, 2005 minimum capital report, except as provided in a plan submitted to OFHEO within 60 days and subject to OFHEO’s approval. Fannie Mae believes it is in compliance with the terms of its agreement with OFHEO.
	The “gross mortgage portfolio” balances set forth in this monthly summary report represent unpaid principal balances, which represent statistical measures rather than amounts computed in accordance with GAAP. “Mortgage portfolio” assets that will be reported to OFHEO under the agreement reflect GAAP adjustments, including mark-to-market adjustments for available-for-sale securities, allowance for loan losses and unamortized premiums and discounts. These adjustments are not reflected in the “gross mortgage portfolio” amounts shown in this report.
•	Total business volume increased to $52.1 billion, compared with $47.3 billion the previous month, driven by a rise in portfolio purchases to $23.0 billion.
•	Fannie Mae’s book of business grew at a compound annualized rate of 7.3 percent in April compared with 7.5 percent in March.
•	Net retained commitments rose to $17.4 billion in April from $16.6 billion the previous month.
•	Lender-originated MBS issues rose to $37.0 billion from $34.2 billion the previous month.
•	The conventional single-family delinquency rate (90 days or more delinquent) fell seven basis points in March to 0.67 percent. The multifamily delinquency rate (60 days or more delinquent) fell one basis point to 0.26 percent.
•	The duration gap on Fannie Mae’s portfolio averaged one month in April.
