Linda Chatman Thomsen
Linda, the first woman to serve as the Director of the SEC’s Division of Enforcement, concentrates in matters related to the enforcement of the federal securities laws. Major financial institutions, regulated entities, public companies and senior executives turn to her for a broad range of typically nonpublic matters, including insider trading, foreign corrupt practices, financial reporting, manipulation and regulatory compliance. She helps clients balance business and leadership needs in times of crisis.
Linda has represented clients in enforcement investigations and inquiries by the SEC and self-regulatory agencies including FINRA; in enforcement matters before other agencies including DOJ and the CFTC; and in internal investigations.
Clients benefit from Linda’s 14 years of service at the SEC. As Enforcement Director from 2005 to 2009, she led the Enron investigation, the auction rate securities settlements, the stock options backdating cases and the expansion of FCPA enforcement.
Linda has been at the forefront of high-profile matters relating to:
- High-frequency trading
- Mortgage-backed securities
- The "princelings" investigations
- Analyst surveys and alpha-capture programs
- Trading-surveillance policies and procedures
- Market disruptions
- FCPA violations
- The sovereign wealth fund business
Her recent public representations include:
- Liquidnet, a dark pool, in connection with an SEC investigation into the use of confidential customer data, in a matter resolved with a non-fraud settlement
- MF Global's independent directors in connection with all litigation and investigations surrounding MF Global's well-publicized failure and bankruptcy
- A major financial institution in connection with inquiries by the SEC related to a $3.7 billion capital-reporting error
- Fortune Global 100 corporation in an SEC investigation related to business with a state-owned company in South Africa
- The board of directors of Direct Edge in connection with an SEC multidisciplinary inquiry relating to potential violations concerning technology, information security, securities compliance and governance
- McGraw Hill Financial, Inc. and Standard & Poor's Financial Services LLC in connection with lawsuits brought by the SEC, DOJ and Attorneys General of numerous states concerning the ratings of residential mortgage-backed securities
- Two stock exchanges, EDGA and EDGX, formerly owned by Direct Edge Holdings and since acquired by BATS Global Markets in connection with an investigation by the SEC related to high-frequency trading
Many of Linda's most successful matters have not resulted in public charges and therefore remain confidential.
