NOTE 23. EARNINGS PER SHARE

Earnings per share and the weighted-average number of diluted shares are computed as follows (in thousands, except per share data):

	Year ended June 30,
	2017		2016		2015
Net income attributable to CACI	$	163,671	$	142,799	$	126,195

Dilutive effect of SSARs/stock options and RSUs/restricted shares after application of treasury stock method		668		540		384
Dilutive effect of the warrants		—		—		56
Weighted-average number of diluted shares outstanding during the period		25,069		24,802		24,388
Basic earnings per share	$	6.71	$	5.89	$	5.27

There were no anti-dilutive common stock equivalents for the years ended June 30, 2017, 2016, and 2015 because the Company’s average stock price exceeded the exercise price of all shares outstanding. The calculation of diluted earnings per share for the year ended June 30, 2017 includes the shares underlying the performance-based RSUs granted in September 2016, September 2015 and September 2014. During the year ended June 30, 2015 the Company issued 0.5 million shares of common stock for settlement of its warrants. Pursuant to the terms of the warrant transaction, the warrants settled daily over 90 trading days which began in August 2014 and end in December 2014. The contingently issuable shares that may have resulted from the maturity of the warrants were included in the computation of diluted earnings per share because the Company’s average stock price during the first and second quarters of the year ended June 30, 2015 was greater than the warrants’ exercise price of $68.31.
