FedEx disclosed this week that it is investigating potential violations of the Foreign Corrupt Practices Act.

The allegations center around potential bribery payments made to customs officials in Kenya in exchange for clearing shipments without inspection. “Allegations were brought to FedEx's attention in December 2013 regarding possible violations of the FCPA,” says Bonnie Kourvelas, a FedEx spokesperson.

“The company immediately began investigating these allegations, retaining an outside U.S. law firm, as well as an external audit team in East Africa,” Kourvelas says.

FedEx additionally informed the Department of Justice and Securities and Exchange Commission of the allegations shortly after learning of them, and have been engaged in a cooperative dialogue with both agencies since that time, the company stated.

“To date, FedEx has not found anything to substantiate the allegations,” Kourvelas adds, “but the investigation is ongoing.”
