Edward “Ted” Siedle, Of Counsel

In 2017, Ted secured the largest SEC whistleblower award in history– $48 million– related to a $307 million JP Morgan Chase settlement that charged the bank with failing to disclose certain conflicts of interest to some of its wealth management clients. In 2016, he obtained the first whistleblower award in the history of the State of Indiana on behalf of a client.

Ted knows what it’s like to be a whistleblower because he was a successful whistleblower himself. Early in his legal career, after leaving the SEC’s Division of Investment Management and becoming Director of Compliance-Legal Counsel of a major mutual fund complex, he was the original mutual fund whistleblower in 1988.

Ted is also the nation’s leading expert in forensic investigations of money managers and pensions, focusing upon excessive and hidden investment fees and risks, conflicts of interest and wrongdoing. He has investigated well-over $1 trillion in retirement plans. Prior investigations include the state of Rhode Island, state of North Carolina, the Alabama State Employees Pension, Wal-Mart, Cities of Nashville, Chattanooga and Jacksonville, Towns of Jupiter and Longboat Key, Caterpillar, Boeing, Northrup Grumman, John Deere, Bechtel, ABB, Edison, Shelby County, Tennessee, Fidelity Investments, JP Morgan, Sanford Bernstein, Banco Santander, US Airways Pilots Pension and New York State Teamsters Pension.
