(3)Investment firms may use the clearing services of multiple clearing members. For positions for which K-CMG is applied, the determination of the amount of total margin required from the investment firm should be comprehensive and include the full margin required by all clearing members. Therefore, where an investment firm uses K-CMG for positions that are subject to clearing by multiple clearing members, CMG should be calculated as the sum of the margins required across all clearing members. An investment firm should, accordingly, first calculate the total daily amount of margin required as the sum of the total margin required by all clearing members, before determining the third highest amount of total margins required on a daily basis as required by Article 23(2) of Regulation (EU) 2019/2033.
