| (9) | Net Income Per Share
Basic net income per share is based on the weighted average number of shares of common stock outstanding. Diluted net income per share is based upon the weighted average number of common shares outstanding and dilutive common stock equivalent shares outstanding during each period. The weighted average number of shares used to compute basic and diluted net income per share consisted of the following (in thousands):
|  | Three Months Ended |  |  | Nine Months Ended |
|  | September 30, |  |  | September 30, |
|  | 2021 |  |  | 2020 |  |  | 2021 |  |  | 2020 |
Basic weighted average common shares outstanding |  |  | 7,531 |  |  |  | 7,495 |  |  |  | 7,522 |  |  |  | 7,480 |
Weighted average common equivalent shares due to restricted stock, stock options and RSUs |  |  | 66 |  |  |  | 60 |  |  |  | 63 |  |  |  | 67 |
Diluted weighted average common shares outstanding |  |  | 7,597 |  |  |  | 7,555 |  |  |  | 7,585 |  |  |  | 7,547 |
The computation of diluted earnings per share excludes the effect of the potential exercise of stock awards, including stock options, when the average market price of the common stock is lower than the exercise price of the related options during the period. These outstanding stock awards are not included in the computation of diluted income per share because the effect would be antidilutive. For both the three- and nine-month periods ended September 30, 2021, the number of stock awards excluded from the computation of diluted earnings per share for this reason was 10,716. For both the three- and nine-month periods ended September 30, 2020, the number of stock awards excluded from the computation of diluted earnings per share for this reason was 14,892.
