Hundreds of auditors at accounting giant Ernst & Young cheated on ethics tests they were required to take to get or maintain their professional licenses, and the company withheld evidence of the misconduct from federal authorities investigating the matter, according to the Securities and Exchange Commission, the Washington Post reported. In response, the SEC is imposing a $100 million fine on the company, the largest ever on an audit firm, the agency announced Tuesday. “This action involves breaches of trust by gatekeepers within the gatekeeper entrusted to audit many of our nation’s public companies,” SEC enforcement director Gurbir Grewal said in a statement. “It’s simply outrageous that the very professionals responsible for catching cheating by clients cheated on ethics exams of all things.” In a statement, Ernst & Young admitted to the SEC’s charges and said it is complying with the agency’s penalty. The agency found that beginning in 2017, 49 Ernst & Young professionals shared or received answers to ethics exams they needed to pass to get licensed as certified public accountants. Hundreds more cheated on courses they needed to take to maintain their standing with state oversight boards, while others who didn’t participate themselves helped facilitate the behavior, the SEC said.
