The U.S. Department of Justice and the Securities and Exchange Commission are pursuing fraud charges over manipulation of a non-GAAP metric at a publicly traded real estate investment trust.

A U.S. Attorney’s Office in New York says two former executives at Brixmor Property Group Inc. have pled guilty to charges of conspiracy to commit securities fraud and making false statements to the SEC and are cooperating with the investigation. Two more former executives are facing multiple counts of similar charges, along with additional charges related to false certifications.
