Hardware maker Dell has restated its earnings, stating that they are $92 million less than originally claimed.

The restated earnings followed a year-long internal investigation that revealed Dell employees had misled auditors and manipulated results to meet performance goals for more than four years. The reports covered the years 2003 through 2006, as well as the first quarter of fiscal 2007.

It cost Dell $205 million to find the missing $92 million. Dell also faces shareholder lawsuits over the missing millions.
