PART 1 U.K.

Exposure measures and adjustments U.K.

18. ‘Current Exposure’ means the larger of zero or the market value of a transaction or portfolio of transactions within a netting set with a counterparty that would be lost upon the default of the counterparty, assuming no recovery on the value of those transactions in bankruptcy. U.K.

19. ‘Peak Exposure’ means a high percentile of the distribution of exposures at any particular future date before the maturity date of the longest transaction in the netting set. U.K.

20. ‘Expected Exposure (EE)’ means the average of the distribution of exposures at any particular future date before the longest maturity transaction in the netting set matures. U.K.

21. ‘Effective Expected Exposure (Effective EE) at a specific date’ means the maximum expected exposure that occurs at that date or any prior date. Alternatively, it may be defined for a specific date as the greater of the expected exposure at that date, or the effective exposure at the previous date. U.K.

22. ‘Expected Positive Exposure (EPE)’ means the weighted average over time of expected exposures where the weights are the proportion that an individual expected exposure represents of the entire time interval. When calculating the minimum capital requirement, the average is taken over the first year or, if all the contracts within the netting set mature within less than one year, over the time period of the longest maturity contract in the netting set. U.K.

23. ‘Effective Expected Positive Exposure (Effective EPE)’ means the weighted average over time of effective expected exposure over the first year, or, if all the contracts within the netting set mature within less than one year, over the time period of the longest maturity contract in the netting set, where the weights are the proportion that an individual expected exposure represents of the entire time interval. U.K.

24. ‘Credit Valuation Adjustment’ means an adjustment to the mid-market valuation of the portfolio of transactions with a counterparty. This adjustment reflects the market value of the credit risk due to any failure to perform on contractual agreements with a counterparty. This adjustment may reflect the market value of the credit risk of the counterparty or the market value of the credit risk of both the credit institution and the counterparty. U.K.

25. ‘One-Sided Credit Valuation Adjustment’ means a credit valuation adjustment that reflects the market value of the credit risk of the counterparty to the credit institution, but does not reflect the market value of the credit risk of the credit institution to the counterparty. U.K.
