Note 1: The risk weight should not be lower than the risk weight that applies for national currency exposures of the central government of the third country in question under BIPRU 3.5. That means that this risk weight only applies if the third country is one of those to which BIPRU 3.4.6 R (Preferential risk weight for exposures of the central government of countries outside the EEA that apply equivalent prudential standards) applies. |
|||
Note 2: This is a transitional measure. It lasts until 31 December 2012. |
|||
Note 3: The risk weight should not be lower than the risk weight that applies for exposures of the central government of the EEA State in question in the currency of another EEA State under BIPRU 3.5. |
