Former Banker Pleads Guilty in Olympus Accounting Case A former bank vice president pleaded guilty on Wednesday to a fraud charge, admitting he helped former executives of Olympus carry out a fraud involving several hundred million dollars that deceived investors into thinking the company was stronger financially than it was. The former banker, Chan Ming Fon, 50, pleaded guilty in Federal District Court in Manhattan to federal conspiracy to commit wire fraud. He said he helped the executives as they misrepresented the financial condition of Olympus, a maker of medical devices and cameras, from at least 2004 through 2010 while he worked at two international financial institutions. "I acknowledge that my conduct was wrong," Mr. Chan told Judge Laura Taylor Swain. Mr. Chan, a Taiwanese citizen and Singapore resident, was arrested in December in Los Angeles. He was expected to remain in the Los Angeles area after posting $1.5 million cash as part of his $3 million bail. Prosecutors said Mr. Chan managed a fund that held a bond investment portfolio belonging to Olympus. The government said Olympus executives directed Mr. Chan to transfer the portfolio to an Olympus-controlled entity, making the company appear stronger financially than it was. In a plea deal with the government that requires his cooperation, Mr. Chan acknowledged that he provided false and misleading information about the investment portfolio to Olympus's auditor, misleading investors into thinking the portfolio remained in safe and secure bonds. Mr. Chan received more than $10 million in compensation for cooperating with the corrupt executives. At the time of his arrest, the United States attorney in Manhattan, Preet Bharara, said Mr. Chan "was handsomely paid to play an international shell game with hundreds of millions of dollars of assets in order to allow Olympus to keep a massive accounting fraud going for years." A year ago, Olympus, its former president and two other executives pleaded guilty in Tokyo to criminal charges related to a two-decade $1.7 billion accounting fraud aimed at covering up huge investment losses.
