Disc Crv

Key Disc Crv in Yield Curve Tnb refers to an optional exogeneous discounting yield curve used to perform "exogenous dual bootstrapping".
On its absence, a regular bootstrapping is performed, whereby the input rates are used for both discounting and forecasting.
On its presence, a "exogenous dual bootstrapping" takes place, whereby the input rates are used for forecasting forward rates but discounting is done with the curve supplied here.
This results in a final curve that does not assume that the input market swap rates are risk-free.
This curve can be used to forecast forward rates that take into account the risk premium associated with the market swap rates.
Expects an object of type Yield Curve.
