Ref Prd End

Function Ref Prd End within Bond with keys Bond Ref Prd End keys returns the end date(s) of the reference period(s) of the referenced bond(s) containing a given reference date Tˢ
Note the reference period can differ from the corresponding accrual period and is needed in the calculation of the time length of the accrual period by a few day count conventions, such as ACT/ACT(ICMA)

If the settlement date Tˢ is not explicitly given, it will be set to the bond's settlement date as implied by a trade transaction assumed to occur on the trade date T₀ (typically today).
