Securities and Exchange (SEC) Experience

Prior to entering private practice, Thomas spent nearly 20 years at the Securities and Exchange Commission in Washington, D.C.

From 1987 to 1999, Thomas served as an Assistant Chief Litigation Counsel in the SEC’s Division of Enforcement, prosecuting an array of civil proceedings before several federal courts across the United States and administratively before the SEC. He came to be recognized within the ranks of the SEC staff as the SEC’s "expert" on investigating and prosecuting market manipulation cases. But, his case load implicated the entire panoply of securities regulation, including:

  • Market manipulation
  • Pump & Dump schemes (civil and criminal)
  • Reverse mergers
  • Unlawful sales practices by brokers
  • Insider trading
  • Financial fraud
  • SEC reporting
  • "Prime bank" trading schemes
  • Unregistered securities offerings, and
  • Offshore and international securities frauds, including "Reg S" violations

While an SEC Assistant Chief Litigation Counsel, his high profile matters included civilly prosecuting a Nigerian repo and reverse repo trader who operated under multiple aliases and duped several Asian, United States and British banks and broker-dealers; civilly prosecuting the head trader, broker and others for stock manipulation during the Market Break of 1987; signing original complaint in the O'Hagan case, which ultimately upheld the "misappropriation theory" of insider trading; and, obtaining first officer and director bar of chairman of financial institution (public bank holding company) under Remedies Act of 1990.

From 1979 to 1987, Thomas served as Branch Chief and then as Special Counsel in the SEC's Division of Market Regulation, the division which regulates the stock and options exchanges, where he processed SRO rule proposals and provided interpretive advice to various segments of the securities industry and attorneys representing that industry on such topics as exchange trading, options trading, market making (Underwriter Stabilization Practices using Greenshoe), trading practices in connections with IPOs and contingency offerings, tender offer practices, broker-dealer and transfer agent regulation, and back office and clearing agent issues. He also participated in the approval of "new options" products in the early 1980s, including stock index options, futures on stock indices, and foreign currency options.

Department of Justice (DOJ) Experience

While at the SEC, Thomas also served as a Special Assistant United States Attorney for the Central District of California, the Western District of New York, and the Eastern District of Pennsylvania. In that capacity, in conjunction with the U.S. Attorney’s Office for each district, he successfully co-prosecuted several persons indicted for market manipulation, bank fraud and tax fraud. In Los Angeles, he successfully co-prosecuted a nationwide market manipulation that involved more than 25 broker-dealers located throughout the United States. United States v. Robert Gutstein (C.D. Cal. 1991). In Philadelphia, he was successful in co-prosecuting a complex market manipulation scheme that involved a conspiracy between a Salt Lake City stock rental firm and numerous offshore reinsurance companies that had booked manipulated stocks on their financial statements, but then failed to provide back-up insurance to a major medical company in Pennsylvania. The collapse of the scheme left policyholders on the Eastern Seaboard facing millions of dollars of unpaid insurance claims. United States v. Rennert (E.D. Pa. 1996). While at the SEC, Thomas also routinely provided advice to U.S. Attorney offices across the United States on the criminal implications of securities fraud.

International Experience

Thomas appeared on behalf of the U.S government in several court proceedings in Europe and the Netherlands Antilles. Thomas has also been called upon by several European and Asian governments and securities exchanges to advise them on investigating and prosecuting market manipulation and market abuse schemes, as well as on drafting statutes, regulations and codes of conduct outlawing market abuse and insider dealing. He has made presentations to the Swedish and English authorities on these topics, and in 1999 was asked to advise Great Britain’s House of Lords about proposed bills before Parliament on enforcement issues and market abuse. Further, prior to its official opening in December 2000 as the new regulator of securities, commodities, banks and insurance, he provided advice to the Financial Services Authority (FSA) in London on the drafting of its Code of Conduct under its new statutes. Further, the European Commission’s Internal Market Directorate General (formerly DG-15) consulted with Thomas during the early stages of development of its general directive to member states outlawing market abuse in the European Union.
