Which of the statement about the investment firm is INCORRECT? [br] [originalte

[7D] Japan’s financial watchdog has told an investment firm to halt its operations on suspicion that it has lost most of the $2.3bn funds it manages.
    Operations at AIJ Investment Advisors, which [7A] manages group pension funds for more than a hundred firms, have been suspended for a month.
    It came after reports in Japan alleged that [7B] the firm may have covered up losses for years.
    Authorities said they would also probe all other investment firms in Japan. " [7C] The Financial Services Agency (FSA), together with the labour ministry, will take every possible step to prevent this kind of incident from happening again," said Shozaburo Jimi, the head of the FSA.
    [8] The report has taken analysts and industry watchers by surprise.
    "It is very difficult to understand how they were able to hide all these losses," Yuuki Sakurai of Fukuko Capital Management told the BBC.
    "They should have had accounting firms checking all their balance sheets."
    At the same time, analysts said that investment firms also provided their clients with reports of how and where their money had been invested.
    They said it was difficult to believe that none of the firm’s clients has raised any concerns.
