14. Earnings Per Share

The following is a reconciliation of the basic and diluted earnings per share computation:


	Three Months Ended March 31,
	2018		2017
Net income	$	9,424	$	6,880


	(shares in thousands)
Shares of common stock and common stock equivalents:
Weighted average common shares used in basic computation		135,329		134,385
Dilutive effect of common stock equivalents		1,139		1,124

Weighted average common shares used in dilutive computation		136,468		135,509

Basic earnings per share	$	0.07	$	0.05
Diluted earnings per share	$	0.07	$	0.05

In the table above, unvested share-based awards that have non-forfeitable rights to dividends or dividend equivalents are treated as a separate class of securities in calculating EPS.

Diluted earnings per share is calculated under both the treasury stock and two-class method and reflects the reduction in earnings per share assuming options or other contracts to issue common stock were exercised or converted into common stock (if dilutive). The calculation that results in the most dilutive earnings per share amount for common stock is reported in the Company’s consolidated financial statements. The Company excluded 1,101,513 and 1,549,440 common stock equivalents from its computation of diluted earnings per share for the three months ended March 31, 2018 and 2017, respectively, as they were determined to be anti-dilutive.
