2. Income (loss) per Common Share

The following table sets forth the computation of basic and diluted net income (loss) per common share:

	2015			2014			2013
	(Dollars In Thousands, Except Per Share Amounts)
Numerator:
Net (loss) income:	$	(34,765	)	$	19,634		$	54,962
Dividend requirements on Series E Redeemable    Preferred		(2,287	)		—			—
Dividends on Series B Preferred		(240	)		(240	)		(240	)
Dividends on Series D Preferred		(60	)		(60	)		(60	)
Accretion of Series E Redeemable Preferred		(686	)		—			—
Total dividends, dividend requirements and    accretion on preferred stocks		(3,273	)		(300	)		(300	)
Numerator for basic net income (loss) per common    share - net income (loss) attributable to common    stockholders		(38,038	)		19,334			54,662
Dividends on convertible preferred stocks assumed     to be converted, if dilutive		300			300			300
Numerator for diluted net income (loss) per common    share	$	(37,738	)	$	19,634		$	54,962
Denominator:
Denominator for basic net income (loss) per common    share - weighted- average shares		22,758,873			22,575,053			22,465,176
Effect of dilutive securities:
Convertible preferred stocks		—			916,666			916,666
Unvested restricted stock		—			—			—
Warrants		—			—			—
Stock options		—			175,751			215,124
Dilutive potential common shares		—			1,092,417			1,131,790
Denominator for dilutive net income (loss) per common    share - adjusted weighted-average shares and assumed    conversions		22,758,873			23,667,470			23,596,966
Basic net income (loss) per common share	$	(1.67	)	$	0.86		$	2.43
Diluted net income (loss) per common share	$	(1.67	)	$	0.83		$	2.33

The following weighted-average shares of securities were not included in the computation of diluted net income (loss) per common share as their effect would have been antidilutive:

	2015		2014		2013
Convertible preferred stocks		916,666		—		—
Stock options		898,582		392,314		246,391
Warrants		314,808		—		—
Series E redeemable preferred stock - embedded derivative		34,998		—		—
Restricted stock		1,448		—		—
		2,166,502		392,314		246,391
