On Pmt Val Delay

Key On Pmt Val Delay in Contingent Claim refers to an optional time interval that becomes relevant only if the trigger function Trigger Fn evaluates to TRUE during a particular simulation run.
In that case, the payoff function defined through the key On Pmt Fn must be valuated based on the observed quotes of the u underlyings defined in the related Payoff Policy.
By default, the latter valuation takes place immediately, i.e. the required u quotes are observed at the same time when the respective trigger function fires up.
It is possible though to postpone the payoff valuation to a latter time by one of two alternative ways:
1)By adding the time interval defined here to the trigger activation time.
2)By specifying the payoff valuation time directly through the key On Pmt Val Date.
Expects an optional object of type Period.
Note that not both of these two specifications above may be used simultaneously.
If none of them is used, the payoff function is valuated when the respective trigger function fires up, as mentioned above.
