Off Pmt Currency

Key Off Pmt Currency in Contingent Claim refers to the optional denomination currency of the paid out amount that becomes relevant only if the trigger function Trigger Fn evaluates to FALSE during a particular simulation run.
Apart from the fact that the entry here applies on the absence of a triggered event, in all other respects it works just like the equivalent entry On Pmt Currency.
