WorldCom's former top accountant has pleaded guilty to conspiracy and securities fraud.
Buford Yates, ex-director of general accounting at WorldCom, is the second executive to plead guilty in connection with the $7bn accounting scandal at the telecoms company.
Yates said he had followed orders that originated "at the highest levels" of the company to inflate earnings.
His supervisors ordered him to make adjustments to the company's financial statements that reduced WorldCom's reported expenses and increased its reported revenue between 2000 and 2002, Yates said.
WorldCom's former controller, David Myers, last month also pleaded guilty to securities fraud, conspiracy to commit securities fraud, and filing false information with the US Securities and Exchange Commission.
