In June 2008 police also announced they were investigating Sahashi for possible embezzlement in the course of business for his ordering the transfer of the entire balance of a separately managed employee fund to a Nova business account to allow the payment of refunds to students. Sahashi, who owned the affiliate firm that handled the money transfer, did so in July 2007 to cover operating costs without the approval of employees. Nova employees had made monthly contributions from their pay to fund a mutual aid organization that covered the costs of business trips and occasions of congratulations or condolence. Rarely used, it had an accumulated balance of 300 million yen at the time of the transfer.
