EARNINGS PER SHARE [Abstract]

EARNINGS PER SHARE

Note 2:                          EARNINGS (LOSS) PER SHARE               The following table provides further share information used in calculating our earnings (loss) per share for the periods presented herein.  Basic earnings (loss) per share was calculated by dividing net income (loss) attributable to AMCOL shareholders by the weighted average number of common shares outstanding during each period.  Diluted earnings per share was calculated by dividing net income (loss) attributable to AMCOL shareholders by the weighted average common shares outstanding after consideration of the dilutive effect of stock compensation awards outstanding during each period.
