Specifies the dividend payout ratio associated with an equity underlyer. A basket swap can have different payout ratios across the various underlying constituents. In certain cases the actual ratio is not known on trade inception, and only general conditions are then specified. Users should note that FpML makes a distinction between the derivative contract and the underlyer of the contract. It would be better if the agreed dividend payout on a derivative contract was modelled at the level of the derivative contract, an approach which may be adopted in the next major version of FpML.
