This measurement shows the estimated loss in pre-tax market value of Fannie Mae’s assets and liabilities from an immediate adverse 25 LIBOR yield 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 yiechange in slope that results in a flatter LIBOR yield curve, and reports the more adverse of the two results.
