Swiss Bankers Charged With Helping U.S. Taxpayers Hide Assets United States prosecutors charged three Swiss bankers on Tuesday of conspiring with wealthy American taxpayers to hide more than $1.2 billion in assets from tax authorities. The office of the Manhattan United States attorney said in a statement that the indictment accused the bankers of trying to "capture business lost by UBS A.G. and another large international Swiss bank in the wake of widespread news reports that the Internal Revenue Service was investigating UBS" in 2008 and 2009. Neither the international Swiss bank nor the other purported co-conspirators were identified by prosecutors. The three bankers worked as client advisers at a Zurich bank branch and hid certain Swiss bank accounts and the income they had generated, prosecutors said. They did not identify the bank branch. The indictment filed in United States District Court in New York identified the three bankers as Michael Berlinka, Urs Frei and Roger Keller. It said they all lived in Switzerland. Their lawyers were not immediately known. If convicted, the bankers face a maximum prison term of five years under the conspiracy charge.
