## Consistency Check

Subtype of Job RequestThis is a boolean that is

**if and only if the Fwd Surp due to Curves equals the PnL due to Curves**

*TRUE*It is also part of the PnL Explain table PnLExplain Table that is produced in association with the key PnL Explain when a tradable is priced with the Advanced Pricing model input.

In fact, these two values must be equal and the boolean here must be

*TRUE*The reason is the following:

As shown in the table PnLExplain Table, the following hold:

Fwd Surp due to Curves = H - Fᵣ

PnL due to Curves = H - S/P + C - Fᵣ + F

Therefore, these two values being equal is equivalent to:

S/P = C + F

which must hold as long as the spot price, carry and forward have been calculated correctly because:

S is the present value of all cash flows

C*P is the present value of those cash flows occurring at or before horizon

F*P is the present value of those cash flows occurring strictly after horizon
