Share-based Payment Arrangement [Abstract] |
Share-based Payment Arrangement [Text Block] | Note 18—Share-Based Payments Under the Company’s 2002 Stock Award and Incentive Plan (“the Plan”), which incorporated its Third Amended and Restated 1995 Stock Option Plan, the Company has reserved shares of its common stock for issuance upon the exercise of options granted under the Plan, as well as for the awarding of other securities. Under the Plan, employees (including officers), non-employee directors and independent consultants may be granted options to purchase shares of common stock, restricted stock units and other securities (see Note 15 - Common Stock and Preferred Stock). The vesting of these share-based awards may vary, but typically vest over a requisite service period or are based on performance criteria, with a maximum vesting period of four years. Restricted shares typically vest in the same manner, with the exception of certain awards vesting over one to three years. Share-based compensation expense is recognized on a straight-line basis over the requisite service period. Compensation expense for performance-awards is measured based on the amount of shares ultimately expected to vest, estimated at each reporting date based on management expectations regarding the relevant performance criteria. As of December 31, 2020, 1,180,226 shares were available for future grant. Additional shares may become available to the extent that options or shares of restricted stock presently outstanding under the Plan terminate, expire, or are forfeited. Restricted Stock Under the Plan, share-based compensation payments may include the issuance of shares of restricted stock. Restricted stock award grants are based upon employment contracts, which vary by individual and year, and are subject to vesting conditions. The following table summarizes the restricted stock award activity, annually, for the year ended December 31, 2020, 2019 and 2018:
