The contractor`s general approach is that used when no participant in the contract is identified as the principal; Where an entity is identified as the contracting entity for a contract, the other party or contracting parties shall be identified as counterparties. Note that the alternative use of the notion of consideration, which is the equivalent of a particular person in a contract, is not the concept considered here, and these two concepts are inconsistent. Roll-on risk is the amount for which the expected positive exposure is undervalued where future transactions with a counterparty are likely to be carried out continuously, but the additional exposure generated by those future transactions is not taken into account in the calculation of the expected positive exposure. . . .
