In addition to granting Performance Shares, the Company began awarding shares of restricted stock to key management during fiscal 2006. Shares of restricted stock vest equally over four years from the date of grant. Compensation expense for restricted stock is determined by the fair market value of the Companys stock on the date of grant, as determined by the average of the high and low trading price, and is expensed on a straight-line basis over the service period. During fiscal 2006, the Company recognized expense related to restricted stock awards the Company has agreed to make but has been unable to grant, pending becoming current in its periodic SEC reporting.
