Section 628.53 - Equity exposures to investment funds(a)Available approaches.(1) A System institution must determine the risk-weighted asset amount of an equity exposure to an investment fund under the full look-through approach described in paragraph (b) of this section, the simple modified look-through approach described in paragraph (c) of this section, or the alterative modified look-through approach described paragraph (d) of this section, provided, however, that the minimum risk weight that may be assigned to an equity exposure under this section is 20 percent.(3) If an equity exposure to an investment fund is part of a hedge pair and the System institution does not use the full look-through approach, the System institution must use the ineffective portion of the hedge pair as determined under § 628.52(c) as the adjusted carrying value for the equity exposure to the investment fund. The risk-weighted asset amount of the effective portion of the hedge pair is equal to its adjusted carrying value.(b)Full look-through approach. A System institution that is able to calculate a risk-weighted asset amount for its proportional ownership share of each exposure held by the investment fund (as calculated under this subpart as if the proportional ownership share of the adjusted carrying value of each exposure were held directly by the System institution) may set the risk-weighted asset amount of the System institution's exposure to the fund equal to the product of:(1) The aggregate risk-weighted asset amounts of the exposures held by the fund as if they were held directly by the System institution; and(2) The System institution's proportional ownership share of the fund.(c)Simple modified look-through approach. Under the simple modified look-through approach, the risk-weighted asset amount for a System institution's equity exposure to an investment fund equals the adjusted carrying value of the equity exposure multiplied by the highest risk weight that applies to any exposure the fund is permitted to hold under the prospectus, partnership agreement, or similar agreement that defines the fund's permissible investments (excluding derivative contracts that are used for hedging rather than speculative purposes and that do not constitute a material portion of the fund's exposures).(d)Alternative modified look-through approach. Under the alternative modified look-through approach, a System institution may assign the adjusted carrying value of an equity exposure to an investment fund on a pro rata basis to different risk weight categories under this subpart based on the investment limits in the fund's prospectus, partnership agreement, or similar contract that defines the fund's permissible investments. The risk-weighted asset amount for the System institution's equity exposure to the investment fund equals the sum of each portion of the adjusted carrying value assigned to an exposure type multiplied by the applicable risk weight under this subpart. If the sum of the investment limits for all exposure types within the fund exceeds 100 percent, the System institution must assume that the fund invests to the maximum extent permitted under its investment limits in the exposure type with the highest applicable risk weight under this subpart and continues to make investments in order of the exposure type with the next highest applicable risk weight under this subpart until the maximum total investment level is reached. If more than one exposure type applies to an exposure, the System institution must use the highest applicable risk weight. A System institution may exclude derivative contracts held by the fund that are used for hedging rather than for speculative purposes and do not constitute a material portion of the fund's exposures.
