In the case of a retail exposure, a value adjustment resulting from significant perceived decline in credit quality falling within BIPRU 4.3.63 R (3) need not necessarily be taken as an indication of unlikeliness to pay if a firm employs formulaic portfolio provisioning based on a number of days overdue for its retail exposures. However, if such an exposure reaches the compulsory days past due indicator for the purposes of the definition of default it should automatically be deemed
While the qualitative requirements in BIPRU 4 are important for all portfolios, they are of even greater importance in those cases where a firm lacks sufficient historical data to calibrate or validate its estimates of PD, LGD or conversion factors on the basis of proven statistical significance, sometimes referred to as low default portfolios.
The expected loss amounts1 for equity exposures must be calculated according to the following formula:(1) expected loss amount = EL × exposure value; and(2) the EL values must be the following:(a) expected loss (EL) = 0.8% for private equity exposures in sufficiently diversified portfolios;(b) expected loss (EL) = 0.8% for exchange traded equity exposures; and(c) expected loss (EL) = 2.4% for all other equity exposures.[Note:BCD Annex VII Part 1 point 32]
A firm must make use of other quantitative validation tools and comparisons with external data sources. The analysis must be based on data that are appropriate to the portfolio, are updated regularly, and cover a relevant observation period. A firm's internal assessments of the performance of its models must be based on as long a period as possible.[Note:BCD Annex VII Part 4 point 121]
A firm with portfolios concentrated in a particular market segment and range of default risk must have enough obligor grades within that range to avoid undue concentrations of obligors in a particular grade. Significant concentrations within a single grade must be supported by convincing empirical evidence that the obligor grade covers a reasonably narrow PD band and that the default risk posed by all obligors in the grade falls within that band.[Note:BCD Annex VII Part 4 point
(1) A firm should achieve full roll-out of the IRB approach to all its exposures, subject to the exemptions outlined in BIPRU 4.2.26 R, within the period specified in its IRB permission. A firm should not retain a permanent mix of portfolios on the standardised approach and the IRB approach, on the foundation IRB approach and the advanced IRB approach or on a mixture of all approaches with the exception of portfolios covered by those exemptions.(2) This applies to a move:(a) from
A firm may choose to use the supervisory volatility adjustments approach or the own estimates of volatility adjustments approach independently of the choice it has made between the standardised approach and the IRB approach for the calculation of risk weighted exposure amounts. However, if a firm seeks to use the own estimates of volatility adjustments approach, it must do so for the full range of instrument types, excluding immaterial portfolios where it may use the supervisory
