(4)The BCBS and IOSCO have now amended their schedule for the implementation of the requirements concerning the exchange of collateral to support the smooth and orderly implementation of the margin requirements at the international level, and in particular because smaller counterparties were not able to meet the originally envisaged deadline. In addition, there are still third countries in which certain products are not subject to equivalent margin requirements. That amendment to the implementation schedule the BCBS and the IOSCO should therefore be reflected in the phase-in provided for in Delegated Regulation (EU) 2016/2251.
