Method to compute the present value and its sensitivities for a FRA with discounting. The present value is computed as the (forward rate - FRA rate) multiplied by the notional and the payment accrual factor and discounted to settlement. The discounting to settlement is done using the forward rate over the fixing period. The value is further discounted from settlement to today using the discounting curve. $$ \begin{equation*} P^D(0,t_1)\frac{\delta_P(F-K)}{1+\delta_P F} \quad \mbox{and}\quad F = \frac{1}{\delta_F}\left( \frac{P^j(0,t_1)}{P^j(0,t_2)}-1\right) \end{equation*} $$ This approach is valid subject to a independence hypothesis between the discounting curve and some spread.
