Risk weights are based on the risk weight of issuer as described in BIPRU 3.4.110 R. The risk weight of the issuer for this purpose should be calculated under the simplified approach. |

Generally 1250%. May look through to underlying exposures if BIPRU 9 allows. |
Use the BIPRU 9rules for unrated exposures under the standardised approach |

Short term exposures with rating |
See BIPRU 3.4.112 R. Not applicable as uses ECAI ratings. |

May look through to underlying under BIPRU 3.4.123 R |
Various |
Simplified approach does not apply. Normal rules apply. May use simplified approach to underlying if simplified approach applies to underlying. |
|
May use average risk weight under BIPRU 3.4.124 R |
Various |
Simplified approach does not apply. Normal rules apply. May use simplified approach to underlyings if simplified approach applies to underlying. |

Note3: 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 UK3 that apply equivalent prudential standards) applies. |
