Title 12
SECTION 628.52
628.52 Simple risk-weight approach (SRWA).
§ 628.52 Simple risk-weight approach (SRWA).(a) General. Under the SRWA, a System institution's total risk-weighted assets for equity exposures equals the sum of the risk-weighted asset amounts for each of the System institution's individual equity exposures (other than equity exposures to an investment fund) as determined under this section and the risk-weighted asset amounts for each of the System institution's individual equity exposures to an investment fund as determined under § 628.53.
(b) SRWA computation for individual equity exposures. A System institution must determine the risk-weighted asset amount for an individual equity exposure (other than an equity exposure to an investment fund) by multiplying the adjusted carrying value of the equity exposure or the effective portion and ineffective portion of a hedge pair (as defined in paragraph (c) of this section) by the lowest applicable risk weight in this paragraph.
(1) Zero-percent (0%) risk weight equity exposures. An equity exposure to a sovereign, the Bank for International Settlements, the European Central Bank, the European Commission, the International Monetary Fund, an MDB, and any other entity whose credit exposures receive a 0-percent risk weight under § 628.32 may be assigned a 0-percent risk weight.
(2) Twenty-percent (20%) risk weight equity exposures. An equity exposure to a PSE or the Federal Agricultural Mortgage Corporation (Farmer Mac) must be assigned a 20-percent risk weight.
(3) One hundred-percent (100%) risk weight equity exposures. The equity exposures set forth in this paragraph (b)(3) must be assigned a 100-percent risk weight:
(i) [Reserved]
(ii) Effective portion of hedge pairs. The effective portion of a hedge pair.
(iii) Non-significant equity exposures. Equity exposures, excluding exposures to an investment firm that would meet the definition of a traditional securitization in § 628.2 were it not for the application of paragraph (8) of that definition and has greater than immaterial leverage, to the extent that aggregate adjusted carrying value of the exposures does not exceed 10 percent of the System institution's total capital.
(A) Equity exposures subject to paragraph (b)(3)(iii) of this section include:
(1) Equity exposures to unconsolidated unincorporated business entities and equity exposures held through consolidated unincorporated business entities, as authorized by subpart J of part 611 of this chapter; and
(2) [Reserved]
(3) Equity exposures to an unconsolidated rural business investment company and equity exposures held through a consolidated rural business investment company described in 7 U.S.C. 2009cc et seq.
(B) To compute the aggregate adjusted carrying value of a System institution's equity exposures for purposes of this section, the System institution may exclude equity exposures described in paragraphs (b)(1) and (2) and (b)(3)(ii) of this section, the equity exposure in a hedge pair with the smaller adjusted carrying value, and a proportion of each equity exposure to an investment fund equal to the proportion of the assets of the investment fund that are not equity exposures or that meet the criterion of paragraph (b)(3)(i) of this section. If a System institution does not know the actual holdings of the investment fund, the System institution may calculate the proportion of the assets of the fund that are not equity exposures based on the terms of the prospectus, partnership agreement, or similar contract that defines the fund's permissible investments. If the sum of the investment limits for all exposure classes within the fund exceeds 100 percent, the System institution must assume for purposes of this section that the investment fund invests to the maximum extent possible in equity exposures.
(C) When determining which of a System institution's equity exposures qualify for a 100-percent risk weight under this paragraph, a System institution first must include equity exposures to unconsolidated rural business investment companies or held through consolidated rural business investment companies described in 7 U.S.C. 2009cc et seq.; then must include equity exposures to unconsolidated unincorporated business entities and equity exposures held through consolidated unincorporated business entities, as authorized by subpart J of part 611 of this chapter; then must include publicly traded equity exposures (including those held indirectly through investment funds); and then must include non-publicly traded equity exposures (including those held indirectly through investment funds).
(4) Other equity exposures. The risk weight for any equity exposure that does not qualify for a risk weight under paragraph (b)(1), (2), (3), or (7) of this section will be determined by the FCA.
(5)-(6) [Reserved]
(7) Six hundred-percent (600%) risk weight equity exposures. An equity exposure to an investment firm must be assigned a 600-percent risk weight, provided that the investment firm:
(i) Would meet the definition of a traditional securitization in § 628.2 were it not for the application of paragraph (8) of that definition; and
(ii) Has greater than immaterial leverage.
(c) Hedge transactions - (1) Hedge pair. A hedge pair is two equity exposures that form an effective hedge so long as each equity exposure is publicly traded or has a return that is primarily based on a publicly traded equity exposure.
(2) Effective hedge. Two equity exposures form an effective hedge if the exposures either have the same remaining maturity or each has a remaining maturity of at least 3 months; the hedge relationship is formally documented in a prospective manner (that is, before the System institution acquires at least one of the equity exposures); the documentation specifies the measure of effectiveness (E) the System institution will use for the hedge relationship throughout the life of the transaction; and the hedge relationship has an E greater than or equal to 0.8. A System institution must measure E at least quarterly and must use one of three alternative measures of E as set forth in this paragraph (c):
(i) Under the dollar-offset method of measuring effectiveness, the System institution must determine the ratio of value change (RVC). The RVC is the ratio of the cumulative sum of the changes in value of one equity exposure to the cumulative sum of the changes in the value of the other equity exposure. If RVC is positive, the hedge is not effective and E equals 0. If RVC is negative and greater than or equal to −1 (that is, less than 0 and greater than or equal to −1), then E equals the absolute value of RVC. If RVC is negative and less than −1, then E equals 2 plus RVC.
(ii) Under the variability-reduction method of measuring effectiveness:
Where: Xt = At × Bt; At = the value at time t of one exposure in a hedge pair; and Bt = the value at time t of the other exposure in a hedge pair.(iii) Under the regression method of measuring effectiveness, E equals the coefficient of determination of a regression in which the change in value of one exposure in a hedge pair is the dependent variable and the change in value of the other exposure in a hedge pair is the independent variable. However, if the estimated regression coefficient is positive, then E equals 0.
(3) The effective portion of a hedge pair is E multiplied by the greater of the adjusted carrying values of the equity exposures forming a hedge pair.
(4) The ineffective portion of a hedge pair is (1-E) multiplied by the greater of the adjusted carrying values of the equity exposures forming a hedge pair.
