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 dchange in the fair value of the net assets. The calculation excludes any sensitivity of the guaranty business. Serious Delinquency Rates. A measure of credit performance and indicator of future defaults for the single-family and multifamily mortgage credit books. We include single-family loans that are three mo

This measurement shows the estimated loss in pre-tax market value of Fannie Mae’s assets and liabilities from an immediate adverse 25 basis poyield curve. To calculate the adverse change in the slope of the LIBOR yield curve, the company calculates the effect of a 25 basis point change in slope that results in a steeper LIBOR yield curve and thslope that results in a flatter LIBOR yield curve, and reports the more adverse of the two results. The amounts shown are estimates, not precise measurements. The measurement excludes any sensitivity Mae tracks the daily average of this measurement for the reported month.
