1. Competent authorities of an institution acting as a clearing member may require any CCP in which that institution acts as a clearing member to undertake the calculation referred to in Article 1(1) and the reporting referred to in Article 2(1) with either a daily or a weekly frequency in either of the following situations:
where, following the default of one clearing member, a CCP is obliged to use any portion of the pre-funded financial resources that it contributed to the default waterfall in accordance with Article 43 of Regulation (EU) No 648/2012;
where, following the default of one clearing member a CCP is obliged to make use of the default fund contributions of non-defaulting clearing members in accordance with Article 42 of Regulation (EU) No 648/2012.
2. Competent authorities shall base the choice between daily and weekly frequency as provided for in paragraph 1 on the degree of actual or foreseen depletion of the pre-funded financial resources.
3. Where competent authorities require a higher frequency of calculation and reporting from a CCP in accordance with point (a) of paragraph 1, the higher frequency shall apply until the pre-funded financial resources that were contributed by the CCP to the default waterfall are restored at the levels set in Article 35 of Commission Delegated Regulation (EU) No 153/2013 4.
4. Where competent authorities require a higher frequency of calculation and reporting from a CCP in accordance with point (b) of paragraph 1, the higher frequency shall apply until the default fund contributions of the non-defaulting members of the CCP are restored to the levels set out in Article 42 of Regulation (EU) No 648/2012.
