Earnings Per Share

The following is a reconciliation of the amounts utilized in the computation of basic and diluted earnings per share for the three and six months ended March 31, 2018 and April 1, 2017 (in thousands, except per share amounts):



	Three Months Ended				Six Months Ended
	March 31, 2018		April 1, 2017		March 31, 2018			April 1, 2017
Net income (loss)	$	12,290	$	29,295	$	(86,203	)	$	57,474
Basic weighted average common shares outstanding	33,538		33,703		33,552			33,619
Dilutive effect of share-based awards outstanding	849		999		—			1,012
Diluted weighted average shares outstanding	34,387		34,702		33,552			34,631
Earnings (loss) per share:
Basic	$	0.37	$	0.87	$	(2.57	)	$	1.71
Diluted	$	0.36	$	0.84	$	(2.57	)	$	1.66

For the three and six months ended March 31, 2018, share-based awards for approximately 0.3 million shares were not included in the computation of diluted earnings per share as they were antidilutive. For the six months ended March 31, 2018, the total number of potentially dilutive share-based awards was 2.0 million. However, these awards were not included in the computation of diluted loss per share, as doing so would have decreased the loss per share.

For the three and six months ended April 1, 2017, share-based awards for approximately 0.1 million and 0.9 million shares, respectively, were not included in the computation of diluted earnings per share as they were antidilutive.
