This study was based on an analysis of data provided by a sample of financial institutions particularly exposed to this risk, supplemented by interviews or on-site inspections. This included an analysis of qualitative and quantitative information on their internal frameworks and experience in dealing with this risk. The ACPR also collected, for each institution, a sample consisting of the 50 largest cases by amount over a certain period.

The report was shared within the ACPR's AML/CTF Consultative Commission to raise awareness among professionals about the risks of rebound accounts and enrich the study with their experiences.

However, the best practices and areas of concern identified in this study are primarily addressed to the financial institutions most exposed to this risk. A high number of recalls related to fraud, suspicious transaction reports, judicial requisitions – or a significant year-on-year increase in such requests – are key indicators to be taken into account when assessing the level of exposure to this risk.
