Reconciliation of Shares Used in Calculating Basic and Diluted Earnings Per Share

A reconciliation of shares used in calculating basic and diluted (loss) earnings per share is as follows:


	The year ended December 31,
	2014		2013		2012
Basic weighted-average shares outstanding		88,045		106,947		112,866
Effect of common stock equivalents – stock options and non-vested stock under employee compensation plans⁽¹⁾		—		966		1,129

Diluted weighted-average shares outstanding⁽¹⁾		88,045		107,913		113,995

Weighted-average anti-dilutive common stock equivalents⁽¹⁾		6,937		5,337		7,167

For periods in which losses are presented, dilutive earnings per share calculations do not differ from basic earnings per share because the effects of any potential common stock equivalents are anti-dilutive and therefore not included in the calculation of dilutive earnings per share. For the year ended December 31, 2014, those potential shares totaled 3,046 which are included in the weighted average anti-dilutive common stock equivalents above, in addition to 3,891 of out of the money anti-dilutive common stock equivalents for the year ended December 31, 2014.
