Olympus Corp. President Shuichi Takayama, one of the defendants in a suit over the firm's massive hidden losses, said Wednesday he will stay at his post until the second half of April, when the company will hold a shareholders' meeting.

Takayama's announcement came as the camera and endoscope maker becomes involved in multiple lawsuits.

On Tuesday, an Olympus shareholder sued 14 board members who sacked whistle-blowing British former chief executive Michael C. Woodford.
