Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

We have incentive stock plans under which restricted stock units (“RSUs”) were granted to employees. Our annual grant of share-based compensation to employees takes place during the first quarter of each fiscal year. Under the fair value method, compensation cost is measured at the grant date based on the fair value of the award and is recognized over the service period which generally corresponds to the vesting period. Awards under our incentive plans generally vest over periods ranging from one to three years.

The number of shares granted to employees and the weighted average fair value per share during the periods presented were (shares in thousands):
