The amounts recorded as share based compensation expense consist of restricted stock awards issued to officers and employees that have vesting periods up to three years. Awards are typically made pursuant to employment agreements. Restricted stock awards are granted out of the Company’s 2021 and 2020 Equity Compensation Plans.

We determine the fair value of restricted stock and RSUs based on the closing price of our stock on the date of grant. We generally recognize compensation expense related to restricted stock and RSUs on a straight-line basis over the period during which the restriction lapses. Forfeitures are recognized in the period in which they occur. The following table presents a summary of the Company’s restricted stock grants outstanding at December 31, 2021, and restricted stock activity during the year ended December 31, 2021 (“Price” reflects the weighted average share price at the date of grant):
