- (a)General. A Board-regulated institution may calculate its risk-weighted asset amount for equity exposures using the IMA by modeling publicly traded and non-publicly traded equity exposures (in accordance with paragraph (c) of this section) or by modeling only publicly traded equity exposures (in accordance with paragraphs (c) and (d) of this section).
- (b)Qualifying criteria. To qualify to use the IMA to calculate risk-weighted assets for equity exposures, a Board-regulated institution must receive prior written approval from the Board. To receive such approval, the Board-regulated institution must demonstrate to the Board's satisfaction that the Board-regulated institution meets the following criteria:
- (1)The Board-regulated institution must have one or more models that:
- (2)The Board-regulated institution's model must produce an estimate of potential losses for its modeled equity exposures that is no less than the estimate of potential losses produced by a VaR methodology employing a 99th percentile one-tailed confidence interval of the distribution of quarterly returns for a benchmark portfolio of equity exposures comparable to the Board-regulated institution's modeled equity exposures using a long-term sample period.
- (3)The number of risk factors and exposures in the sample and the data period used for quantification in the Board-regulated institution's model and benchmarking exercise must be sufficient to provide confidence in the accuracy and robustness of the Board-regulated institution's estimates.
- (4)The Board-regulated institution's model and benchmarking process must incorporate data that are relevant in representing the risk profile of the Board-regulated institution's modeled equity exposures, and must include data from at least one equity market cycle containing adverse market movements relevant to the risk profile of the Board-regulated institution's modeled equity exposures. In addition, the Board-regulated institution's benchmarking exercise must be based on daily market prices for the benchmark portfolio. If the Board-regulated institution's model uses a scenario methodology, the Board-regulated institution must demonstrate that the model produces a conservative estimate of potential losses on the Board-regulated institution's modeled equity exposures over a relevant long-term market cycle. If the Board-regulated institution employs risk factor models, the Board-regulated institution must demonstrate through empirical analysis the appropriateness of the risk factors used.
- (5)The Board-regulated institution must be able to demonstrate, using theoretical arguments and empirical evidence, that any proxies used in the modeling process are comparable to the Board-regulated institution's modeled equity exposures and that the Board-regulated institution has made appropriate adjustments for differences. The Board-regulated institution must derive any proxies for its modeled equity exposures and benchmark portfolio using historical market data that are relevant to the Board-regulated institution's modeled equity exposures and benchmark portfolio (or, where not, must use appropriately adjusted data), and such proxies must be robust estimates of the risk of the Board-regulated institution's modeled equity exposures.
- (c)Risk-weighted assets calculation for a Board-regulated institution using the IMA for publicly traded and non-publicly traded equity exposures. If a Board-regulated institution models publicly traded and non-publicly traded equity exposures, the Board-regulated institution's aggregate risk-weighted asset amount for its equity exposures is equal to the sum of:
- (1)The risk-weighted asset amount of each equity exposure that qualifies for a 0 percent, 20 percent, or 100 percent risk weight under § 217.152(b)(1) through (b)(3)(i) (as determined under § 217.152) and each equity exposure to an investment fund (as determined under § 217.154); and
- (2)The greater of:
- (i)The estimate of potential losses on the Board-regulated institution's equity exposures (other than equity exposures referenced in paragraph (c)(1) of this section) generated by the Board-regulated institution's internal equity exposure model multiplied by 12.5; or
- (ii)The sum of:
- (A)200 percent multiplied by the aggregate adjusted carrying value of the Board-regulated institution's publicly traded equity exposures that do not belong to a hedge pair, do not qualify for a 0 percent, 20 percent, or 100 percent risk weight under § 217.152(b)(1) through (b)(3)(i), and are not equity exposures to an investment fund;
- (B)200 percent multiplied by the aggregate ineffective portion of all hedge pairs; and
- (C)300 percent multiplied by the aggregate adjusted carrying value of the Board-regulated institution's equity exposures that are not publicly traded, do not qualify for a 0 percent, 20 percent, or 100 percent risk weight under § 217.152(b)(1) through (b)(3)(i), and are not equity exposures to an investment fund.
- (d)Risk-weighted assets calculation for a Board-regulated institution using the IMA only for publicly traded equity exposures. If a Board-regulated institution models only publicly traded equity exposures, the Board-regulated institution's aggregate risk-weighted asset amount for its equity exposures is equal to the sum of:
- (1)The risk-weighted asset amount of each equity exposure that qualifies for a 0 percent, 20 percent, or 100 percent risk weight under §§ 217.152(b)(1) through (b)(3)(i) (as determined under § 217.152), each equity exposure that qualifies for a 400 percent risk weight under § 217.152(b)(5) or a 600 percent risk weight under § 217.152(b)(6) (as determined under § 217.152), and each equity exposure to an investment fund (as determined under § 217.154); and
- (2)The greater of:
- (i)The estimate of potential losses on the Board-regulated institution's equity exposures (other than equity exposures referenced in paragraph (d)(1) of this section) generated by the Board-regulated institution's internal equity exposure model multiplied by 12.5; or
- (ii)The sum of:
- (A)200 percent multiplied by the aggregate adjusted carrying value of the Board-regulated institution's publicly traded equity exposures that do not belong to a hedge pair, do not qualify for a 0 percent, 20 percent, or 100 percent risk weight under § 217.152(b)(1) through (b)(3)(i), and are not equity exposures to an investment fund; and
- (B)200 percent multiplied by the aggregate ineffective portion of all hedge pairs.
