The Company recognizes compensation expense on the restricted stock units over the period of time the restrictions are in place (four years from the grant date for the 2015, 2016, 2017, 2018 and 2019 grants). The amount of expense recorded each period reflects the changes in the Company’s stock price during such period. As of March 31, 2021, the total unrecognized compensation expense related to the restricted stock unit grants under the 2009 Plan was $74,000. The Company also has an Omnibus Stock Ownership and Long Term Incentive Plan that was approved by shareholders on May 7, 2020 (the “2020 Plan”) whereby certain stock-based rights, such as stock options, restricted stock, restricted stock units, performance units, stock appreciation rights or book value shares, may be granted to eligible directors and employees.

All stock-based rights under the 2020 Plan must be granted or awarded by May 7, 2030 (or ten years from the 2020 Plan effective date).

The Company recognized compensation expense for restricted stock unit awards granted under the 2009 Plan and 2020 Plan of $44,000 for the three months ended March 31, 2021. The Company recognized a $77,000 credit to compensation expense for restricted stock unit awards granted under the 2009 Plan for the three months ended March 31, 2020 due to a reduction in the Company’s stock price from $32.85 per share at December 31, 2019, compared to $20.36 per share at March 31, 2020.
