Wal-Mart Stores Inc. has reorganized its compliance department and hired a global chief compliance officer.

A Reuters report says that its compliance, ethics, investigations and legal units will all report to Wal-Mart's general counsel, Jeff Gearhart, starting on December 1. Jay Jorgensen, who once served as a law clerk to former U.S. Supreme Court Chief Justice William Rehnquist and was most recently a partner at the law firm Sidley Austin, was named global chief compliance officer.

The company has spent more than $30 million in the past 17 months to update its global anti-corruption program, with 79,000 hours logged and more than 1,000 interviews of market personnel, the report said.

Wal-Mart also named Daniel Trujillo as chief compliance officer for Wal-Mart International, and Tracy Reinhold as vice president of global investigations, both new positions for the company.
