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)20192018
Basic weighted average shares outstanding64,597  64,827  
Dilutive effect of unvested RSUs161  150  
Denominator for diluted earnings per share64,758  64,977  

Our dilutive earnings per share for the three months ended December 31, 2019 and 2018, excludes any effect from approximately 274,000 and 282,000 unvested restricted stock units, respectively, as adding them to our calculation would have been antidilutive.
