Equity Compensation Plan Information	Note 10 - Equity Compensation Plan Information At the 2018 Annual Meeting of Shareholders, First United Corporation’s shareholders approved the First United Corporation 2018 Equity Compensation Plan (the “Equity Plan”) which authorizes the issuance of up to 325,000 shares of common stock to employees, directors and qualifying consultants pursuant to stock options, stock appreciation rights, stock awards, dividend equivalents, and other stock-based awards. The Corporation complies with the provisions of ASC Topic 718, Compensation-Stock Compensation, in measuring and disclosing stock compensation cost. The measurement objective in ASC Paragraph 718-10-30-6 requires public companies to measure the cost of employee services received in exchange for an award of equity instruments based on the grant date fair value of the award. The cost is recognized in expense over the period in which an employee is required to provide service in exchange for the award (the vesting period). Pursuant to First United Corporation’s director compensation policy, each director receives an annual retainer of 1,000 shares of First United Corporation common stock, plus $10,000 to be paid, at the director’s election, in cash or additional shares of common stock. In June 2020, a total of 13,160 fully vested shares of common stock were issued to directors, which had a grant date fair market value of $14.52 per share. In July 2020, a total of 916 fully vested shares of common stock were issued to a new director, which had a grant date fair market value of $11.22 per share. In May 2021, a total of 12,726 fully vested shares of common stock were issued to directors, which had a grant date fair value of $18.50 per share. Director stock compensation expense was $191,717 for the nine months ended September 30, 2021 and $158,795 for the nine months ended September 30, 2020. Director stock compensation expense was $58,857 for the three months ended September 30, 2021 and $52,114 for the three months ended September 30, 2020. Restricted Stock Units On March 26, 2020, pursuant to the Corporation’s Long Term Incentive Plan (the "LTIP"), which is a sub-plan of the Equity Plan, the Compensation Committee of First United Corporation’s Board of Directors (the "Committee") granted RSUs to the Corporation’s principal executive officer, its principal financial officer, and certain of its other executive officers. An RSU contemplates the issuance of shares of common stock of First United Corporation if and when the RSU vests. The RSUs granted to each of the foregoing officers consist of (a) a performance vesting award for a three year performance period ending December 31, 2021, (b) a performance vesting award for a three year performance period ending December 31, 2022, and (c) a time-vesting award that will vest ratably over a three year period beginning on March 26, 2021. Target performance levels were set based on the annual budget which supports the Corporation’s long-term objective of achieving high performance as compared to peers. Threshold performance is the minimum level of acceptable performance as defined by the Committee and maximum performance represented a level potentially achievable under ideal circumstances. Achievement of the threshold performance level would result in each executive participant earning a payout at 50% of his or her respective target award opportunity. Achievement of the target performance level would result in the executive participant earning the target award and achievement at or above the maximum performance level would result in the executive participant earning 150% of the target opportunity. Actual results for any goal that falls between performance levels would be interpolated to calculate a proportionate award. For the performance period ending December 31, 2021, the RSUs’ performance goal is based on earnings per share for the year ending December 31, 2021. For the performance period ending December 31, 2022, the RSUs’ performance goals are based on earnings per share for the year ending December 31, 2022 and growth in tangible book value per share during the performance period. The threshold, target and maximum performance levels for these grants will be disclosed pursuant to Item 402 of Regulation S-K following the conclusion of the applicable performance period. To receive any shares under an RSU, a grantee must be employed by the Corporation or one of its subsidiaries on the applicable vesting date, except that a grantee whose employment terminates prior to such vesting date due to death, disability or retirement will be entitled to a pro-rated portion of the shares subject to the RSUs, assuming that, in the case of performance-vesting RSUs, the performance goals had been met at their "target" levels. In the first quarter of 2020, RSUs relating to 19,934 performance vesting shares and 5,070 time vesting shares (target level) were granted, which had a grant date fair market value of $12.54 per share of common stock underlying each RSU. On March 26, 2021, 1,690 of the 5,070 time vesting shares were issued to participants. Stock compensation expense was $78,381 and $93,727 for the first nine months of 2021 and 2020, respectively. Stock compensation expense was $26,127 and $31,243 for the three month periods ended September 30, 2021 and 2020. Unrecognized compensation expense at September 30, 2021 related to unvested RSUs was $110,173. In May 2021, RSUs relating to 7,389 performance vesting shares and 3,693 time vesting shares (target level) were granted, which had a grant date fair market value of $17.93 per share of common stock underlying each RSU. The performance period for the performance-vesting RSUs is the three year period ending December 31, 2023. The time-vesting RSUs will vest ratably over a three year period beginning on May 5, 2022.
