The weighted average estimated fair value of the Market Condition RSUs that were granted during the six months ended June 30, 2021 was $4.61 per unit. The following assumptions were used to estimate the fair value of the Market Condition RSUs granted during the six months ended June 30, 2021 using a Monte-Carlo valuation simulation:

		2021
Volatility			65.1	%
Risk-free interest rate			0.3	%
Correlation coefficient			35.7	%
Dividend yield			-	%

Earnings (Loss) Per Share

Basic earnings (loss) per share is calculated by dividing net income (loss) by the number of weighted average shares of common stock outstanding during the period. The calculation of diluted earnings per share assumes conversion of stock options, restricted stock units and Market Condition RSUs into common stock using the treasury method. The weighted average number of shares used to compute basic and diluted earnings per share consists of the following:

		Three Months Ended June 30,								Six Months Ended June 30,
(in thousands)		2021				2020				2021				2020
Basic			40,152				38,468				39,960				38,389
Dilutive effect of equity awards			-				-				-				-
Diluted			40,152				38,468				39,960				38,389

The Company has excluded from the shares used in calculating the diluted earnings per common share options, restricted stock units and Market Condition RSUs totaling 4,389,966 and 5,727,716 as of June 30, 2021 and 2020 respectively, as the impact of these shares would be anti-dilutive.
