[1] Included in Other expenses was accrued non-employee Directors’ Compensation of approximately $349,000 at December 31, 2020. In May 2021, the non-employee Directors were compensated for their service through a grant of stock options and therefore the balance of the accrual for Director’s Compensation was $ 0 at June 30, 2021. See Note 10.

[2] Included in other is accrued Board of Directors Compensation of $349,000 and $54,000 as of December 31, 2020 and December 31, 2019, respectively. We anticipate the non-management Board of Directors will be compensated for their service through the issuance of stock compensation after the next Annual Meeting.
