Prudential Regulation Authority Rulebook

1.

Institutions shall calculate the risk-weighted exposure amounts for their exposures in the form of units or shares in a CIU by multiplying the risk-weighted exposure amount of the CIU, calculated in accordance with the approaches set out in paragraphs 2 and 5, with the percentage of units or shares held by those institutions.

2.

Where the conditions set out in Article 132(3) are met, institutions that have sufficient information about the individual underlying exposures of a CIU shall look through to those underlying exposures to calculate the risk-weighted exposure amount of the CIU, risk weighting all underlying exposures of the CIU as if they were directly held by the institutions.

3.

By way of derogation from point (d) of Article 92(3), institutions that calculate the risk-weighted exposure amount of the CIU in accordance with paragraph 1 or 2 of this Article may calculate the own funds requirement for credit valuation adjustment risk of derivative exposures of that CIU as an amount equal to 50% of the own funds requirement for those derivative exposures calculated in accordance with Section 3, 4 or 5 of Chapter 6 of Title Two, as applicable.

By way of derogation from the first subparagraph, an institution may exclude from the calculation of the own funds requirement for credit valuation adjustment risk derivative exposures which would not be subject to that requirement if they were incurred directly by the institution.

4.

Institutions that apply the look-through approach in accordance with paragraphs 2 and 3 of this Article and that meet the conditions for permanent partial use in accordance with Article 150, or that do not meet the conditions for using the methods set out in Chapter 3 or one or more of the methods set out in Chapter 5 for all or parts of the underlying exposures of the CIU, shall calculate risk-weighted exposure amounts and expected loss amounts in accordance with the following principles:

1. (a) for exposures assigned to the equity exposure class referred to in point (e) of Article 147(2), institutions shall apply the simple risk-weight approach set out in Article 155(2);
2. (b) for exposures assigned to the items representing securitisation positions referred to in point (f) of Article 147(2), institutions shall apply the treatment set out in Article 254 as if those exposures were directly held by those institutions;
3. (c) for all other underlying exposures, institutions shall apply the Standardised Approach laid down in Chapter 2 of Title Two.

For the purposes of point (a) of the first subparagraph, where the institution is unable to differentiate between private equity exposures, exchange-traded exposures and other equity exposures, it shall treat the exposures concerned as other equity exposures.

5.

Where the conditions set out in Article 132(3) are met, institutions that do not have sufficient information about the individual underlying exposures of a CIU may calculate the risk-weighted exposure amount for those exposures in accordance with the mandate-based approach set out in Article 132a(2). However, for the exposures listed in points (a), (b) and (c) of paragraph 4 of this Article, institutions shall apply the approaches set out therein.

6.

Subject to Article 132b(2), institutions that do not apply the look-through approach in accordance with paragraphs 2 and 3 of this Article or the mandate-based approach in accordance with paragraph 5 of this Article shall apply the fall-back approach referred to in Article 132(2).

7.

Institutions may calculate the risk-weighted exposure amount for their exposures in the form of units or shares in a CIU by using a combination of the approaches referred to in this rule, provided that the conditions for using those approaches are met.

8.

Institutions that do not have adequate data or information to calculate the risk-weighted amount of a CIU in accordance with the approaches set out in paragraphs 2, 3, 4 and 5 may rely on the calculations of a third party, provided that all the following conditions are met:

1. (a) the third party is one of the following:
1. (i) the depository institution or the depository financial institution of the CIU, provided that the CIU exclusively invests in securities and deposits all securities at that depository institution or depository financial institution;
2. (ii) for CIUs not covered by point (i) of this point, the CIU management company;
2. (b) for exposures other than those listed in points (a), (b) and (c) of paragraph 4 of this rule, the third party carries out the calculation in accordance with the look-through approach set out in Article 132a(1);
3. (c) for exposures listed in points (a), (b) and (c) of paragraph 4, the third party carries out the calculation in accordance with the approaches set out therein;
4. (d) an external auditor has confirmed the correctness of the third party's calculation.

Institutions that rely on third party calculations shall multiply the risk weighted exposure amounts of a CIU's exposures resulting from those calculations by a factor of 1.2.

By way of derogation from the second subparagraph, where the institution has unrestricted access to the detailed calculations carried out by the third party, the 1.2 factor shall not apply. The institution shall provide those calculations to its competent authority upon request.

9.

For the purposes of this rule, Article 132(5) and (6) and Article 132b shall apply. For the purposes of this Article, Article 132c shall apply, using the risk weights calculated in accordance with Chapter 3 of Title Two.
