In this annex we explain the methodological approach of this study. We provide a description of the cross-cutting data-collection activities that were undertaken to address the research questions and the major outputs of the study. This study was reliant upon existing literature and secondary data sources, in addition to primary data collected through interviews with stakeholders, surveys of organisations responsible for asset-seizure and confiscation in the EU, and the collation of cases involving organised crime group (OCG) investment in the legal economy or infiltration of legitimate businesses.
