In 2016 the then-president of Angola, José Eduardo dos Santos, appointed his daughter, Isabel dos Santos, as chairwoman of Sonagol, Angola’s struggling state oil company. Ms. dos Santos quickly recruited the management consulting firms Boston Consulting Group (BCG) and McKinsey and Company to help restructure the company. BCG and McKinsey were not paid directly by Sonangol, however, but rather by a holding company controlled by Ms. dos Santos, Wise Intelligence Services. On paper, Wise Intelligence Services oversaw the consulting firms’ work, but in reality this payment plan enabled Ms. dos Santos to embezzle millions of dollars from the Angolan treasury by overcharging for the consultants’ work and then pocketing the difference. The firms, of course, still received enormous fees, and do not appear to have raised any concerns or objections regarding the highly unusual and suspicious payment arrangements. BCG and McKinsey were not the only Western professional services firms to profit from working with Ms. dos Santos. The accounting firms PwC, Deloitte, KPMG, and Ernst and Young all audited some of the companies owned by Ms. dos Santos and signed off on those companies’ contracts with the Angolan government. In January 2020 Angolan prosecutors announced that they would charge Ms. dos Santos—whose personal wealth is estimated at around $2 billion—with embezzlement of state funds in connection with her business relationships with the Angolan government.
This is far from the first corruption scandal that has implicated the same cohort of large professional services firms. McKinsey has received enormous criticism for its partnership with a company connected to the kleptocratic Gupta family in a $700 million contract with the South African government to resuscitate the country’s failing state-owned power company. Deloitte, Bain, and KPMG have also faced scrutiny for their respective roles in facilitating or otherwise enabling South Africa’s myriad corruption scandals. In Mongolia, McKinsey partnered with a firm owned by a top government official in a contract to reshape the country’s rail system; Mongolian officials ultimately levied corruption charges against three different Mongolians involved in brokering that deal.
These and numerous other scandals illustrate that, far too often, professional services firms have either facilitated, or at best been passively complicit in, the theft of massive sums from state coffers. Why have professional services firms been repeatedly implicated in corruption scandals involving their public sector work? Part of the explanation is simply the inherent risk associated with settings in which developing-country governments, where corruption risks are high to begin with, are handing multi-million dollar contracts to Western firms in an effort to modernize their national infrastructure. But in addition, two structural issues help to explain why accounting and management consulting firms are particularly susceptible to these sorts of problems.
