Earnings Per Share [Abstract]

Net Income (Loss) per Share

4. Net Income (Loss) per Share

Basic net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the weighted-average number of common shares and dilutive common share equivalents then outstanding using the treasury stock method. Common share equivalents consist of the incremental common shares issuable upon the exercise of stock options and vesting of restricted stock awards.

The following table presents the basic and diluted weighted-average shares outstanding for each period presented:

	Three Months Ended				Six Months Ended
	March 31,				March 31,
	2017		2016		2017		2016
Weighted-average common shares outstanding, basic		60,141,580		59,295,990		60,041,332		59,133,569
Effect of dilutive securities:
Stock options		-		-		633,007		696,112
Restricted stock units		-		-		395,599		248,171
Weighted-average common shares outstanding, diluted		60,141,580		59,295,990		61,069,938		60,077,852

The following table includes the number of shares that may be dilutive common shares in the future. These shares were not included in the computation of diluted net income per share because the effect was either anti-dilutive or the requisite performance conditions were not met.
