Securitisation Standardised Approach - Look-through Approach For securitisation calculations, when the financial institution has full knowledge of the composition of the underlying exposures of pool at all time, the institution can apply the “look-through” approach to senior securitization exposures. See OSFI Chapter 7, P134 or Basel Framework, CRE 40.50

Equity Investments in Funds - Look-through Approach The LTA requires a bank to risk weight the underlying exposures of a fund as if the exposures were held directly by the bank. This is the most granular and risk-sensitive approach. It must be used when: (1) there is sufficient and frequent information provided to the bank regarding the underlying exposures of the fund; and (2) such information is verified by an independent third party. See Basel CRE60 Equity Investments in Funds, CRE 60.2

eif_mba

Equity Investments in Funds - Mandate-based Approach The second approach, the MBA, provides a method for calculating regulatory capital that can be used when the conditions for applying the LTA are not met. Under the MBA banks may use the information contained in a fund’s mandate or in the national regulations governing such investment funds. See Basel CRE60 Equity Investments in Funds, CRE 60.6

eif_fb

Equity Investmnets in Funds - Fall-back Approach Where neither the LTA nor the MBA is feasible, banks are required to apply the FBA. The FBA applies a 1250% risk weight to the bank’s equity investment in the fund. See Basel CRE60 Equity investments in funds, CRE 60.8
