(15)It should therefore be concluded that the legal and supervisory arrangements of the CFTC comprising the primary rules and the internal rules and procedures of SIDCOs and the opt-in DCOs which meet the standards set out in this Decision with respect to risk management should be considered legally binding requirements which are equivalent to the requirements laid down in Title IV of Regulation (EU) No 648/2012. Only SIDCOs and opt-in DCOs complying with those legally binding requirements (i.e. the primary rules as complemented by the internal rules and procedures approved by the CFTC and meeting the standards set out in this act) may be eligible for recognition by ESMA, which should verify, in accordance with Article 25(2)(b) of Regulation (EU) No 648/2012, that those standards are part of the internal rules and procedures of any CCP subject to that regime and applying for recognition in the Union. Likewise ESMA monitors in accordance with Article 25(5) of Regulation (EU) No 648/2012 that the equivalent regime as defined in this Decision, including the conditions contained herein, continues to be met and may withdraw the recognition where this is not the case. In particular, ESMA will check that the CCP applies a two-day liquidation period with respect to clearing members' proprietary positions in non-OTC derivative contracts and that the CCP applies measures designed to limit procyclicality that are equivalent in delivering stable and conservative margins to any of the three measures set out under Regulation (EU) No 648/2012, and that the CCP maintains sufficient pre-funded available financial resources enabling it to withstand the default of at least the two clearing members to which it has the largest exposures under extreme but plausible market conditions taking account of additional risks to which those CCPs are exposed arising from the simultaneous failure of entities in the group of the defaulting clearing members.
