Stock-based compensation expense for the three and six months ended June 30, 2022 and 2021 was allocated as follows:
|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |
(in thousands) |  | 2022 |  |  | 2021 |  |  | 2022 |  |  | 2021 |

Total stock-based compensation expenses |  | $ | 1,239 |  |  | $ | 1,164 |  |  | $ | 2,262 |  |  | $ | 2,132 |
As of June 30, 2022, the total compensation costs related to unvested awards not yet recognized is $7.4 million and the weighted average period over which it is expected to be recognized is approximately 1.9 years. The Company did not capitalize any stock-based compensation. The weighted average estimated fair value of the performance-based RSUs that were granted during the six months ended June 30, 2022 was $5.92 per unit. The following assumptions were used to estimate the fair value of the performance-based RSUs granted during the six months ended June 30, 2022 using a Monte-Carlo valuation simulation:
|  | 2022 |
Volatility |  |  | 65.1 | %
Risk-free interest rate |  |  | 1.4 | %
Correlation coefficient |  |  | 38.5 | %
Dividend yield |  |  | - | %
Earnings (Loss) Per Share Basic earnings (loss) per share (EPS) 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, time-based RSUs, and performance-based RSUs into common stock using the treasury method. The weighted average number of shares used to compute basic and diluted EPS consists of the following:
|  | Three Months Ended June 30, |  |  | Six Months Ended June 30, |
(in thousands) |  | 2022 |  |  | 2021 |  |  | 2022 |  |  | 2021 |
Basic |  |  | 41,304 |  |  |  | 40,152 |  |  |  | 41,256 |  |  |  | 39,960 |
Dilutive effect of equity awards |  |  | 1,256 |  |  |  | - |  |  |  | - |  |  |  | - |
Diluted |  |  | 42,560 |  |  |  | 40,152 |  |  |  | 41,256 |  |  |  | 39,960 |
The Company excludes from the calculation of diluted EPS the weighted average shares of underlying stock-based awards if the impact of including these potential shares would be anti-dilutive. The Company has excluded the impact of approximately 0.9 million shares and 4.8 million shares for the three months ended June 30, 2022 and 2021, and 3.7 million shares and 4.7 million shares for the six months ended June 30, 2022 and 2021, respectively.
