For the purposes of Article 50c, the following shall apply:

(a) where the rules of a CCP provide that it use part or all of its financial resources in parallel to the pre-funded contributions of its clearing members in a manner that makes those resources equivalent to pre-funded contributions of a clearing member in terms of how they absorb the losses incurred by the CCP in the case of the default or insolvency of one or more of its clearing members, the CCP shall add the corresponding amount of those resources to DF_CM;

(b) where the rules of a CCP provide that it use part or all of its financial resources to cover its losses due to the default of one or more of its clearing members after it has depleted its default fund, but before it calls on the contractually committed contributions of its clearing members, the CCP shall add the corresponding amount of those additional financial resources (DF^a_CCP) to the total amount of pre-funded contributions (DF) as follows:

DF = DF_CCP + DF_CM + DF^a_CCP.
