(16)The reporting of irregularities, which the depositary of the master UCITS detects in the course of carrying out its depositary function under the national law of its home Member State, aims to protect the feeder UCITS. For that reason no reporting should be required when those irregularities do not have a negative impact on the feeder UCITS. Where irregularities with regard to the master UCITS have a negative impact on the feeder UCITS, the latter should also be informed as to whether and how the irregularities have been resolved. The depositary of the master UCITS should therefore inform the depositary of the feeder UCITS of how the master UCITS has resolved or proposes to resolve the irregularity. If the depositary of the feeder UCITS is not satisfied that the resolution is in the interests of the unit-holders of the feeder UCITS, it should promptly report its view to the feeder UCITS.
