Compensatory ratio hedging is a methodology whereby an amount of a bond
that is hedged by a swap varies during the life of the swap, per a
predetermined schedule, such that the change in the swap's mark-to-market
dollar value is equal to the change in the bond's market value caused by
an equal change in interest rates. The amount of bond being hedged by the
swap will vary over a predetermined period of time to compensate for the
differences in swap and bond valuation drivers. This methodology
establishes a hedge such that an interest rate change has a similar
dollar impact on the swap mark-to-market value and the bond
mark-to-market value thus curtailing some reporting implications of
