But the accounting saga played on for one former high-flying tech company. Shares in business software maker Computer Associates plunged $4.40 or 17.4% to $20.91 on newspaper reports that the FBI and the US Attorney's office had launched investigations into whether it had inflated profits to help pad executive bonuses. CA, which denied knowledge of the inquiries, is headed by Charles Wang, 56, who has topped best-paid executive lists based on an incentive scheme adopted by the company several years ago. In 1999, Wang's compensation including pay, bonuses and share options topped $650m. Last year, when CA's shares were cut in half, he was rewarded to the tune of nearly $120m.
