17.	Earnings per share

No adjustments have been made for the three years ended December 31, 2015, 2014 or 2013 for any common stock equivalents because their effects would be anti-dilutive for purposes of calculating basic and diluted net loss available to common shareholders. Potentially dilutive shares totaled 221,036, 167,583, and 101,672 for 2015, 2014, and 2013, respectively.

Additionally, options to purchase shares of common stock with exercise prices in excess of the average market price of common shares are not included in the computation of diluted earnings per share. There were 812,695, 1,062,198 and 1,186,259 outstanding options not included in the diluted earnings per share computation for the year ended December 31, 2015, 2014 and 2013, respectively, because the inclusion of these options was anti-dilutive.

During the period January 1, 2016, to February 24, 2016, the Company repurchased an additional 417,078 shares of common stock for $15.9 million, which would have changed the number of common shares or potential common shares outstanding for the period ended December 31, 2015, if these transactions had occurred prior to that date.
