The overwhelming majority of banks currently use the so called „percentage of notional“
and „Current Exposure + Add On’’ formulas for the measurement of credit risk in their
derivatives portfolios. However, these approaches do not deliver exposure figures that
adequately describe the counterparty risk of a specific counterparty, because they rely on
a variety of simplifying assumptions that may lead to gross over- or underestimations of
the true counterparty risk. In particular, it is unable to take account for portfolio effects
since it is based on single transaction analysis.
