Bankrupt telecommunications carrier WorldCom has entered into a settlement with the US Securities and Exchange Commission (SEC) over its accounting practices, agreeing to a permanent injunction.

WorldCom, which in July filed for protection under Chapter 11 of the US Bankruptcy Code, is mired in a $9 billion accounting scandal.

Allegations of improper accounting at the Clinton, Mississippi, company have brought shareholder lawsuits and congressional investigations in addition to the SEC's civil suit.

Tuesday's injunction requires WorldCom to: not violate securities laws in the future; provide education and training for senior operational officers and financial reporting staff to prevent future accounting problems; and to retain a consultant to review the effectiveness of WorldCom's accounting controls and policies.
