3.The interaction between the treatment of short term credit assessment under Article 131 and the general preferential treatment for short term exposures set out in paragraph 2 shall be as follows:
(a)If there is no short-term exposure assessment, the general preferential treatment for short-term exposures as specified in paragraph 2 shall apply to all exposures to institutions of up to three months residual maturity;
(b)If there is a short-term assessment and such an assessment determines the application of a more favourable or identical risk weight than the use of the general preferential treatment for short-term exposures, as specified in paragraph 2, then the short-term assessment shall be used for that specific exposure only. Other short-term exposures shall follow the general preferential treatment for short-term exposures, as specified in paragraph 2;
(c)If there is a short-term assessment and such an assessment determines a less favourable risk weight than the use of the general preferential treatment for short-term exposures, as specified in paragraph 2, then the general preferential treatment for short-term exposures shall not be used and all unrated short-term claims shall be assigned the same risk weight as that applied by the specific short-term assessment.
