Earnings Per Share [Abstract]

Computation of Basic and Diluted Earnings per Share

The following is the computation of basic and diluted earnings per share (EPS) from continuing operations attributable to Ashland.  Stock appreciation rights (SARs), stock options and warrants available to purchase shares outstanding for each reporting period whose grant price was greater than the average market price of Ashland Common Stock for each applicable period were not included in the computation of income from continuing operations per diluted share because the effect of these instruments would be antidilutive.  The total number of these shares outstanding was approximately 0.7 million and 1.4 million at June 30, 2018 and 2017, respectively.  Earnings per share is reported under the treasury stock method.
