Article 325 4.

An institution may use a combination of the alternative standardised approach referred to in paragraph 1, point (a), of this Article and the alternative internal model approach referred to in paragraph 1, point (b), of this Article on a permanent basis, provided that the total own funds requirements for market risk calculated using the alternative internal model approach represent at least 10 % of the total own funds requirements for market risk. On an individual basis, an institution shall not use either of those approaches in combination with the simplified standardised approach referred to in paragraph 1, point (c), of this Article. At consolidated level, an institution may use a combination of those three approaches to calculate the own funds requirements for market risk in accordance with Article 325b(4), point (b), as long as the simplified standardised approach is not used in combination with the other two approaches within a single legal entity.
