The delegated EU Regulations 2018/1618 and 2018/1619 will apply from 1 April 2020, which will change the delegated Regulation 231/2013 to the AIFMD ("AIFM Regulation") and the Delegated Regulation 2016/438 to the UCITS Directive ("UCITS Regulation") with regard to the depositary's duties in the case of sub-repositories. The changes allow sub-custodians to keep the assets in omnibus accounts so that a segregation per fund is no longer necessary at all levels of the custody chain. The new AIFM Regulation (see Article 99 para. 1 (a)) and the UCITS Regulation (see Article 16 para. 1 (a)) require that a sub-custodian is able to allocate the assets to the various funds only on the basis of appropriate documentation. At the same time, the flow of information within the custody chain is improved and the documentation and reconciliation processes between the depositary and sub-custodians are strengthened. In addition, AIF depositaries must obtain information about the insolvency law conditions in case of sub-custody in third countries (see Article 99 para. 2a AIFM-VO).
