The newly appointed administrators of the failed Toho Mutual Life Insurance Co. said Monday they will set up an internal committee to investigate if the firm's management is liable for its collapse.

The Life Insurance Association of Japan, certified public accountant Mohachi Sugiyama and lawyer Akira Kosugi will run the company as administrators while assessing its assets and liabilities.

They told a news conference that the Financial Supervisory Agency ordered them to investigate whether the firm's executives are responsible for its collapse.
