Earnings Per Share [Abstract]

Earnings per share

18. Earnings per share

For each of the three years ended December 31, 2014, there were no adjustments to net income (loss) for purposes of calculating basic and diluted net income (loss) available to common shareholders. The following is a reconciliation of the weighted average shares used in the basic and diluted net income (loss) per common share computations.

	Year Ended December 31,
	2014		2013		2012
Weighted average common shares-basic		18,459,054		18,697,228		18,977,263
Effect of diluted securities:
Unexercised stock options net of treasury share    repurchase		—		—		413,150
Weighted average common shares-diluted		18,459,054		18,697,228		19,390,413

No adjustment has been made in 2014 or 2013 for any common stock equivalents because their effects would be anti-dilutive. For 2013 potentially dilutive shares totaled 101,672.

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 1,062,198, 1,186,259 and 789,650 outstanding options not included in the diluted earnings per share computation for the fiscal year ended December 31, 2014, 2013 and 2012, respectively, because the inclusion of these options was anti-dilutive.
