Olympus Urged to Extend Purge of Executives Over Hidden Losses

Olympus Corp.’s admission that three of its top executives colluded to hide losses from investors fails to address the roles played by other officials, according to the company’s biggest overseas shareholder.

The Japanese camera maker’s shares slumped 29 percent yesterday after it reversed weeks of denials that there was any wrongdoing in past acquisitions. The company fired Executive Vice President Hisashi Mori over his role in covering up the losses with former Chairman Tsuyoshi Kikukawa, who resigned last week, and said auditor Hideo Yamada would step down.
