Earnings Per Share [Abstract]  
Earnings Per Share Earnings Per Share
The Company has unvested share-based payment awards with a right to receive non-forfeitable dividends, which are considered participating securities under ASC 260, Earnings Per Share. The Company allocates earnings to participating securities and computes earnings per share using the two-class method. Under the two-class method, net income per share is computed by dividing net income allocated to common shareholders by the weighted average number of common shares outstanding for the period. In applying the two-class method, net income is allocated to both common shares and participating securities based on their respective weighted average shares outstanding for the period. For a period of net loss, net loss is not allocated to participating securities.

The following table sets forth the computation of basic and diluted net income per common share under the two-class method for the three and nine months ended September 30, 2023 and September 30, 2022:
