Earnings Per Share | Earnings Per Share The weighted average number of shares outstanding used to compute earnings per share was as follows:
|  | Three Months Ended December 31,
(shares in thousands) |  | 2018 |  | 2017
Basic weighted average shares outstanding |  | 64,827 |  |  | 65,866 |
Dilutive effect of employee stock options and unvested RSUs |  | 150 |  |  | 311 |
Denominator for diluted earnings per share |  | 64,977 |  |  | 66,177 |
Our dilutive earnings per share for the three months ended December 31, 2018, excludes any effect from approximately 282,000 unvested restricted stock units (RSUs) as adding them to our calculation would be antidilutive. No RSUs have been excluded from the calculation for the three months ended December 31, 2017.
