How can one represent a Full Coupon stub in FpML? For example consider a single currency, fixed / float USD swap with a 26 Month tenor. Fixed Leg has a 6 month payment frequency Float leg has a 3 month payment frequency Effective Date is 12/22/2010 Maturity Date is 02/22/2010 Let’s say this is a Front Short stub. But I want to the stub period to be Full Coupon i.e. the first cashflow on the fixed leg will be from 08/22/2010 to 02/22/2011 and the first cashflow on the float leg will be 11/22/2010 to 02/22/2011. One option I can think of is — for the firstRegularPeriodStart date use 08/22/2010 for fixed and 11/22/2010 for float leg. These dates are before the effective date of the swap. Is there any other way? Regards, Dhiraj
