ICIJ Offshore Leaks methodology: Connections marked registered agent of, registered officer of, beneficial owner of, or intermediary for are sourced from the ICIJ Offshore Leaks Database (Panama Papers, 2016). Being named in the leak as a registered officer, registered agent, beneficial owner, or intermediary is not itself an allegation of wrongdoing — many uses of offshore vehicles are legal. Goblin House surfaces these structural relationships because they document the offshore corporate plumbing behind entities the platform already tracks.
