The former chief financial officer of Safenet Inc. pleaded guilty on Friday to backdating stock options for herself and the former CEO.

Carole Argo, 46 of Baltimore, said that Anthony A. Caputo, Safenet’s former CEO, instructed her to backdate options to October 1, 2001, as that was a time when the company’s stock was relatively inexpensive.  Argo complied, additionally backdating her own stocks, along with those of another employee.

This resulted in Safenet filing an inaccurate report with the Securities and Exchange Commission, Argo said.

Argo and Caputo resigned last year because of an internal investigation looking into Safenet’s stock options grant practices. To date no charges have been filed against Caputo.
