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

	Fiscal Year Ended
	October 2, 2016		September 27, 2015		September 28, 2014
	(in thousands, except per share data)
Net income attributable to Tetra Tech	$	83,783	$	39,074	$	108,266


Weighted-average common shares outstanding – basic		58,186		60,913		64,379
Effect of diluted stock options and unvested restricted stock		780		619		767

Weighted-average common stock outstanding – diluted		58,966		61,532		65,146


Earnings per share attributable to Tetra Tech:
Basic	$	1.44	$	0.64	$	1.68


Diluted	$	1.42	$	0.64	$	1.66

For 2016, 2015 and 2014, 0, 1.0 million and 0 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 for that period. Therefore, their inclusion would have been anti-dilutive.
