When potential FCPA violations rear their head, a thorough investigation into what went wrong and why is crucial. But when you are criss-crossing borders and double-checking every party along a supply chain, the cost of an investigation can easily balloon out of control.

In its March 26 10-K, Wal-Mart reported that it had spent $157 million in the last fiscal year on FCPA investigations, a figure that includes defending related shareholder lawsuits.
