Risk-weighted exposure amounts for equity exposures
Under the simple risk weight approach, the risk-weighted exposure amount shall be calculated in accordance with the formula:
Risk weight (RW) = 190 % for private equity exposures in sufficiently diversified portfolios.
Risk weight (RW) = 290 % for exchange traded equity exposures.
Risk weight (RW) = 370 % for all other equity exposures.
Short cash positions and derivative instruments held in the non-trading book are permitted to offset long positions in the same individual stocks provided that these instruments have been explicitly designated as hedges of specific equity exposures and that they provide a hedge for at least another year. Other short positions are to be treated as if they are long positions with the relevant risk weight assigned to the absolute value of each position. In the context of maturity mismatched positions, the method is that for corporate exposures as set out in Article 162(5).
Institutions may recognise unfunded credit protection obtained on an equity exposure in accordance with the methods set out in Chapter 4. This shall be subject to an LGD of 90 % on the exposure to the provider of the hedge. For private equity exposures in sufficiently diversified portfolios an LGD of 65 % may be used. For these purposes M shall be five years.
Under the internal models approach, the risk-weighted exposure amount shall be the potential loss on the institution's equity exposures as derived using internal value-at-risk models subject to the 99th percentile, one-tailed confidence interval of the difference between quarterly returns and an appropriate risk-free rate computed over a long-term sample period, multiplied by 12,5. The risk-weighted exposure amounts at the equity portfolio level shall not be less than the total of the sums of the following:
the corresponding expected loss amounts multiplied by 12,5.
