Earnings Per Share [Abstract] |
Schedule of Share-based Compensation, Restricted Stock and Restricted Stock Units Activity [Table Text Block] | We have issued restricted stock awards to non-employee members of the board of directors since 2006 and restricted stock units (“RSUs”) to certain senior executives since fiscal 2012 under the Company’s Stock Incentive Plan. Each RSU entitles an executive to receive one share of the Company’s common stock if the executive remains continuously employed with the Company through the end of a three-year service period. The RSUs may be paid in shares of our common stock, cash or both at the discretion of the Compensation Committee of our board of directors. We expect to continue to grant these types of awards annually in the future. The following table sets forth the number of outstanding restricted stock awards and RSUs, net of forfeitures and vested shares, as of the fiscal period-end dates indicated:
