FBI is reviewing troubled banks for accounting issues

Lehman Brothers, Fannie Mae, Freddie Mac and giant insurer American International Group are among 26 companies under review by the US Federal Bureau of Investigation for possible accounting misstatements.

The FBI has come under pressure to hold companies accountable for their actions in the wake of the loan crises which began last year and continues to destabilise the capital markets.

Robert Mueller, an FBI director, pledged to 'pursue these cases as far up the corporate chain as necessary to ensure those responsible receive the justice they deserve', Bloomberg reported.

Mortgage giants Freddie Mac and Fannie Mae were taken over by the US government and together with AIG restated their books correcting billions of dollars in accounting errors, while Lehman filed for bankruptcy. The regulators leading the $700bn (£376bn) rescue plan also asked Congress to approve the use of tax-payers funds.

Fannie Mae has also paid a record $400m to the SEC in 2006 to settle charges that senior executives fraudulently used 'cookie jar' reserves and other accounting gimmicks to hide $10.3bn in losses from 2002 to 2004, so as to maximise bonuses.

Freddie Mac paid $125m in fines in 2003, while earnings between 2000 and 2002 were restated after it discovered derivative-related errors after replacing its former auditors Arthur Andersen. At the time regulators charged that the company manipulated its accounting to push about $5bn in earnings to future quarters.
