Earnings Per Share (''EPS'')

Earnings Per Share (''EPS'')

8.Earnings Per Share (“EPS”)

Basic EPS is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding, less unvested restricted stock for the period.  Diluted EPS is computed by dividing net income by the weighted-average number of common shares outstanding and dilutive potential common shares for the period.  Potential common shares include the weighted-average dilutive effects of outstanding stock options and unvested restricted stock using the treasury stock method.

The following table sets forth the number of weighted-average shares used to compute basic and diluted EPS:

	Three Months Ended				Nine Months Ended
	June 29, 2014		June 30, 2013		June 29, 2014		June 30, 2013
	(in thousands, except per share data)
Net income (loss) attributable to Tetra Tech	$	26,657	$	(78,385)	$	85,680	$	(27,342)
Weighted-average common shares outstanding – basic	64,566		64,832		64,683		64,554
Effect of dilutive stock options and unvested restricted stock	736		–		810		–
Weighted-average common stock outstanding – diluted	65,302		64,832		65,493		64,554
Earnings (loss) per share attributable to Tetra Tech:
Basic	$	0.41	$	(1.21)	$	1.32	$	(0.42)
Diluted	$	0.41	$	(1.21)	$	1.31	$	(0.42)

For the three and nine months ended June 29, 2014, 0.7 million and no options were excluded from the calculation of dilutive potential common shares, respectively.  These options were not included in the computation of dilutive potential common shares because the assumed proceeds per share exceeded the average market price per share during the period.  Therefore, their inclusion would have been anti-dilutive.  The computation of diluted loss per share for the three and nine months ended June 30, 2013 excluded 0.7 million and 0.8 million of potential common shares due to their anti-dilutive effect.
