Earnings Per Share [Abstract]  
Earnings per Share
Earnings per Share
The numerator for both basic and diluted earnings per share is net earnings attributable to CDK. The denominator for basic and diluted earnings per share is based upon the weighted-average number of shares of the Company's common stock outstanding during the reporting periods. Diluted earnings per share also reflects the dilutive effect of unexercised in-the-money stock options and unvested restricted stock.
Holders of certain stock-based compensation awards are eligible to receive dividends as described in Note 7. Net earnings allocated to participating securities were not significant for the three months ended September 30, 2016 and 2015.
The following table summarizes the components of basic and diluted earnings per share.
