Single name exposure
Article 182
1. The capital requirement for market risk concentration shall be calculated on the basis of single name exposures. For this purpose exposures to undertakings which belong to the same corporate group shall be treated as a single name exposure. Similarly, immovable properties which are located in the same building shall be considered as a single immovable property. 2. The exposure at default to a counterparty shall be the sum of the exposures to this counterparty. 3. The exposure at default to a single name exposure shall be the sum of the exposures at default to all counterparties that belong to the single name exposure. 4. The weighted average credit quality step on a single name exposure shall be equal to the rounded-up average of the credit quality steps of all exposures to all counterparties that belong to the single name exposure, weighted by the value of each exposure. 5. For the purposes of paragraph 4, exposures for which a credit assessment by a nominated ECAI is available, shall be assigned a credit quality step in accordance with Chapter 1 Section 2 of this Title. Exposures for which a credit assessment by a nominated ECAI is not available shall be assigned to credit quality step 5.
