Stock-Based Compensation [Abstract]

Stock-Based Compensation

3. Stock-Based Compensation

Stock-based compensation is accounted for in accordance with ASC Topic 718, Compensation – Stock Compensation. Under this guidance, the Company recognizes share-based compensation ratably using the straight-line attribution method over the requisite service period. In addition, pursuant to Accounting Standards Update ("ASU") No. 2016-09, Improvements to Employee Share-Based Payment Accounting, the Company has continued to elect to estimate the amount of expected forfeitures when calculating share-based compensation, instead of accounting for forfeitures as they occur. See Note 13, Recent Accounting Pronouncements, for additional information regarding the adoption of ASU No. 2016-09.
