Computer Associates (CA) has become the latest firm to be investigated for so-called 'pro forma' accounting.
According to reports, CA has used the non-standard accounting practice in its reporting of financial results which, if used alone, can make profits and sales figures misleading.
The New York Times said that former employees had reported CA as using pro forma accounting to inflate its results and, as a result, a preliminary inquiry will be conducted.
In December, US financial regulator the Securities and Exchange Commission warned that companies and investors should view pro forma financial statements "with appropriate and healthy scepticism".
The Commission added that "because pro forma financial information by its very nature departs from traditional accounting conventions, its use can make it hard for investors to compare an issuer's financial information with other reporting periods and with other companies".
Following the collapse of energy giant Enron, US regulators are particularly sensitive to corporate financial misinformation, and IBM also came under fire this week for 'creative accounting'.
It is also believed that other pro forma accounts include those of Cisco and Amazon.
2001 saw CA having to explain away a plethora of bad news ranging from poor customer relations, job cuts, illegal price fixing allegations and, most embarrassing of all, boardroom bust-ups.
