"Intentional" mistake?

The Washington Post reports that (emphasis added):

Royal Ahold NV, the Dutch company that owns several large U.S. retail food chains, said today that it had found $29 million in intentional accounting mistakes in its Tops Markets subsidiary, which operates several hundred supermarkets and convenience stores in New York, Pennsylvania and Ohio.

What's an "intentional mistake"? I thought that was just called "lying." (Thanks to Bernsteinblog for the pointer.)
