Sanjay Kumar, the former CEO of Computer Associates International Inc., pleaded guilty on Monday to obstruction of justice and securities fraud charges.

According to a 2004 indictment, Kumar was so involved with adding revenue to a financial quarter even after it closed that he flew to Paris in July 1999 to complete a deal and signed a contract that had been backdated.

The indictment also charged that executives instructed salespeople to complete deals after the quarter had closed and "cleaned up" contracts by removing time stamps from faxes.

The law allows a maximum sentence of 20 years in prison for the offenses, but the term could be substantially less under federal sentencing guidelines.

In 2004, Kumar was named in a 10-count indictment on charges of obstruction of justice, conspiracy to obstruct justice and making false statements to law enforcement officers.
