Evidence: Sections A to D

From the Dossier

Section A: Firm-specific scandals and accountability failures

Timeline chart with one row per firm: McKinsey, Deloitte, PwC, EY, BCG, Bain, Accenture and KPMG. Numbered markers for Section A entries 1 to 14 sit at their source publication year, 2022 to 2026, with a headline fact for each firm on the right. Entry 14, for KPMG, is a hollow marker because its source gives the year only. — Figure 1. Section A entries by firm and source publication date. Source: Section A, Entries 1–14. The dossier’s investigation window runs August 2020 to August 2026; dates shown are source publication dates, not incident dates.Full size
