A whistleblower received $104 million from the federal government for uncovering his former employer’s business of helping Americans hide their assets from the IRS. The employee was former UBS banker Bradley Birkenfeld. His tips on UBS’s practices led to a 2009 settlement between the federal government and UBS where UBS agreed to pay $780 million in penalties and turn over the account information of thousands of U.S. clients. Under the federal whistleblowing law, a person whose information reveals fraud against the federal government can receive a portion of the money recovered by the government. Mr. Birkenfeld’s lawyers believe this is the largest whistleblower award in history.
