Earnings (Loss) Per Share

6 Months Ended

Jun. 30, 2021

Basic earnings (loss) per share ("EPS") amounts are calculated by dividing net income (loss) allocated to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS amounts assume the issuance of common stock for all potentially dilutive securities.

The following table shows the basic and diluted earnings (loss) per share:
