| Share-based compensation arrangement by share-based payment award, description | On June 18, 2008, the Board of Directors of First United Corporation adopted a Long-Term Incentive Program (the "LTIP"). This program was adopted as a sub-plan of the Omnibus Plan to reward participants for increasing shareholder value, align executive interests with those of shareholders, and serve as a retention tool for key executives. Under the LTIP, participants are granted shares of restricted common stock of First United Corporation. The amount of an award is based on a specified percentage of the participant's salary as of the date of grant. These shares will vest if the Corporation meets or exceeds certain performance thresholds. | ||||
