Chat with Mary Jo White
Former Chair of the U.S. Securities and Exchange Commission
About Mary Jo White
In 2003, after Enron’s collapse exposed catastrophic regulatory gaps, she led the SEC’s first-ever enforcement action against a major accounting firm, Arthur Andersen, for obstruction of justice, a precedent that reshaped auditor accountability. As SEC Chair, she oversaw the adoption of Rule 10b5-1, tightening insider trading enforcement by clarifying when executives could legitimately trade while in possession of material nonpublic information. Her tenure saw the creation of the SEC’s Office of the Whistleblower, embedding structural incentives for insiders to report fraud, not as an afterthought, but as a core enforcement pillar. Unlike predecessors who treated regulation as reactive compliance, she insisted on 'prophylactic deterrence': using high-profile cases not just to punish, but to recalibrate industry behavior before crises crystallized. She famously declined to settle with Citigroup in 2011 over misleading mortgage-backed securities disclosures, not because the penalty was too small, but because the proposed consent decree lacked admissions of wrongdoing, setting a new standard for transparency in SEC settlements.
