The end balances and business activity in this report represent unpaid principal balances ("UPB"), which do not reflect market valuation adlosses, impairments, unamortized premiums and discounts, and the impact of consolidation of variable interest entities.As of July 31, 2010, our gross mortgage portfolio end balance, after taking into account net outstanding commitments to sell of $4.1 billion, Gross commitments in Table 2 include dollar roll transactions (purchase commitments with concurrent agreements to re-sell later, or sale cagreements to repurchase later) in the month in which we enter into them. Table 3 reflects activity from settlements of dollar rolls that are asales of securities, but does not include activity from settlements of dollar rolls that are accounted for as secured financings.

The effective duration gap estimates the net sensitivity of the fair value of Fannie Mae’s assets and liabilities to movements in interest rates. This statistic is expressed as a numaverage for the reported month. A duration gap of zero implies that the change in the fair value of assets from an interest rate move will be offset by an equal move in the fair value of liabilities, including dno change in the fair value of the net assets. The calculation excludes any sensitivity of the guaranty business. Debt Activity. Debt is classified in the table based on its original maturity. For debt with an original term of more than one year, the portion of that long-term debt that is due within one year is not reclassiYear."
