1. The capital requirement for longevity risk referred to in Article 105(3)(b) of Directive 2009/138/EC shall be equal to the loss in basic own funds of insurance and reinsurance undertakings that would result from an instantaneous permanent decrease of 20 % in the mortality rates used for the calculation of technical provisions.

2. The decrease in mortality rates referred to in paragraph 1 shall only apply to those insurance policies for which a decrease in mortality rates leads to an increase in technical provisions without the risk margin. The identification of insurance policies for which a decrease in mortality rates leads to an increase in technical provisions without the risk margin may be based on the following assumptions:

(a) multiple insurance policies in respect of the same insured person may be treated as if they were one insurance policy;

(b) where the calculation of technical provisions is based on groups of policies as referred to in Article 35, the identification of the policies for which technical provisions increase under a decrease of mortality rates may also be based on those groups of policies instead of single policies, provided that it yields a result which is not materially different.

3. With regard to reinsurance obligations, the identification of the policies for which technical provisions increase under a decrease of mortality rates shall apply to the underlying insurance policies only and shall be carried out in accordance with paragraph 2.
