Auditors have signed off on truckstop chain Pilot Flying J's math in determining whether it correctly calculated what it owed trucking company customers in a fuel rebate program that has been the focal point of a federal investigation.

The accounting firm of Horne LLP reviewed Pilot Flying J's earlier internal audit as a condition of its federal class action settlement late last year in which the truckstop operator identified companies it owed money along with interest.

Nearly 8,000 accounts were reviewed between the first of 2005 and mid-July of last year, just three months after an FBI and Federal raid on Pilot Flying J offices.

Since the raid both the company and CEO Jimmy Haslam have denied any wrongdoing, while Haslam has also denied any knowledge of the alleged scheme to bilk customers out of money they were owed to inflate company profits.

Ten former Pilot Flying J employees have pleaded guilty for their roles, but none have been sentenced and are reportedly cooperating with officials who are continuing their investigation. Other employees are still on while some have been fired.

Pilot Flying J also still faces around half a dozen other lawsuits in connection with the alleged scandal from companies that refused to take part in the settlement, now estimated to cost more than $90 million, including legal fees.
