	(Thousands except per share amounts)
Basic earnings per common share:

Diluted earnings per common share:
Net income (loss) attributable to EQT Corporation	$	1,508,529	$	(452,983	)	$	85,171

Potentially dilutive securities:
Stock options and awards (a)	347		—			541
Total	187,727		166,978			152,939
Diluted earnings (loss) per common share	$	8.04	$	(2.71	)	$	0.56

(a) Options to purchase common stock which were excluded from potentially dilutive securities because they were anti-dilutive totaled 429,785 shares and 291,700 shares for the years ended December 31, 2017 and 2015, respectively. In periods when the Company reports a net loss, basic and diluted earnings per common share are equal because all options and restricted stock have an anti-dilutive effect on loss per share. As a result, basic shares equaled diluted shares for the year ended December 31, 2016 because the Company was in a net loss position.
