The Company computes earnings per share in accordance with ASC 260, Earnings Per Share. Basic earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding during the period. Diluted earnings per share adjusts basic earnings per share for the effects of warrants, restricted stock, stock options and other potentially dilutive financial instruments, only in the periods in which the effects are dilutive.

For the three months ended March 31, 2021, there were warrants to purchase 1,051,664 shares of common stock and options to purchase 25,000 shares of common stock excluded from the diluted earnings per share computation. For the three months ended March 31, 2020, there were options to purchase 25,000 shares of common stock excluded from the diluted earnings per share computation. The warrants and stock options were excluded because the impact of the assumed exercise of such warrants and stock options would have been anti-dilutive.

The following table reconciles basic weighted average shares outstanding to diluted weighted average shares outstanding for the three months ended March 31, 2021 and 2020:
