	to common stockholders	$	71,829	$	(8,508)	$	121,851	$	46,551
Denominator for basic earnings per

	Non-vested restricted shares		472		370		506		-
	Convertible senior unsecured notes		1,076		2,737		868		-
Dilutive potential common shares			1,739		3,390		1,544		-
Denominator for diluted earnings per
	share - adjusted weighted average shares		297,995		276,481		294,590		266,602
Basic earnings per share		$	0.24	$	(0.03)	$	0.42	$	0.17
Diluted earnings per share		$	0.24	$	(0.03)	$	0.41	$	0.17

The diluted earnings per share calculations exclude the dilutive effect of zero stock options for the three and six months ended June 30, 2014and June 30, 2013 because the exercise prices were higher than the average share prices. The diluted earnings per share calculation for the six months ended June 30, 2013 excludes the dilutive effect all common stock equivalents as they are anti-dilutive due to the loss from continuing operations attributable to common stockholders. The Series I Cumulative Convertible Perpetual Preferred Stock was not included in the calculations as the effect of conversions into common stock was anti-dilutive.
