The margin rules proposed by the European Supervisory Authorities (the “ESAs”) require IM to be
segregated from proprietary assets on the books and records of a third party holder or custodian,
or via other legally effective arrangements. In addition, the rules require cash IM to be segregated individually, unless other legally effective arrangements are in place to segregate it from proprietary assets. Several additional clarifications and issues are described in the letter sent by ISDA to the ESAs in July 20143. As proposed, we illustrate below the unintended consequences arising from the IM segregation
requirements.
