Earnings Per Share [Abstract]  
Schedule of Earnings Per Share, Basic and Diluted
The following table sets forth the computation of basic and diluted income per share, including a reconciliation of net income and the number of shares used in computing basic and diluted income per share.  Basic income per share is determined using the weighted average shares of common stock (including DSUs) outstanding during the period.  Diluted income per share is determined using the weighted average shares of common stock (including DSUs) outstanding during the period, and assumes all potentially dilutive securities were converted into common shares at the earliest date possible.  There were no potentially dilutive securities outstanding during the years ended December 31, 2022, 2021 and 2020.
