(18)To ensure the stability and integrity of the financial system and to introduce proportionate safeguards, loan-originating AIFs should be subject to a leverage limit that varies depending on whether they are of an open-ended or closed-ended type. The risk to financial stability is greater for open-ended AIFs, which can be subject to high levels of redemptions. In line with the objective of preserving financial stability, the leverage limit should not depend on whether a loan-originating AIF is marketed to professional and retail investors or only to professional investors. The commitment method provides a comprehensive and robust framework for calculating leverage in accordance with international standards, and in particular for taking into account the synthetic leverage created by derivatives. Those leverage limits should not prevent the competent authorities of the home Member State of the AIFM from imposing stricter leverage limits where it is deemed necessary in order to ensure the stability and integrity of the financial system.
