Long-term and short-term credit assessments
Article 140
1. Short-term credit assessments may only be used for short-term asset and off-balance sheet items constituting exposures to institutions and corporates. 2. Any short-term credit assessment shall only apply to the item the short-term credit assessment refers to, and it shall not be used to derive risk weights for any other item, except in the following cases: (a) if a short-term rated facility is assigned a 150 % risk weight, then all unrated unsecured exposures on that obligor whether short-term or long-term shall also be assigned a 150 % risk weight; (b) if a short-term rated facility is assigned a 50 % risk-weight, no unrated short-term exposure shall be assigned a risk weight lower than 100 %.
