The computations of basic and diluted EPS are set forth below:



	For the Three Months Ended March 31,
	2019				2018
	(in thousands, except per share amounts, unaudited)
Numerator for basic and diluted EPS — net income (loss)	$	(15,386	)		$	6,368
Denominator for basic EPS — weighted average number of shares	23,956				29,755
Add — dilutive effect of:
Restricted stock units	—			(1)	444		(1)
Denominator for diluted EPS — weighted average number of shares and dilutive securities	23,956				30,199
Earnings (loss) per share:
Basic EPS	$	(0.64	)		$	0.21
Diluted EPS	$	(0.64	)		$	0.21

Beginning with the quarter ended September 30, 2018, the weighted number of shares and dilutive potential shares include 334,048 shares of common stock that will be issued to certain selling unitholders of Cogent in the second quarter of 2019 as the revenue target related to the Earnout was achieved during the quarter ended September 30, 2018. See “Note 4 — Fair Value of Financial Instruments”, “Note 7 — Equity” and “Note 12 — Subsequent Events”.

(1) Excludes 1,994,492 and 1,255,997 outstanding restricted stock units that were antidilutive under the treasury stock method for the three months ended March 31, 2019 and March 31, 2018, respectively, and thus were not included in the above calculation. The incremental shares that could be included in the diluted EPS calculation in future periods will vary based on a variety of factors, including the future share price and the amount of unrecognized compensation cost. The incremental shares included, if any, would be less than the number of outstanding restricted stock units. As a result of the loss in the first quarter of 2019, all unamortized restricted stock units, or 4,053,441 units, were antidilutive in the period. If not for the loss in the period, 657,255 restricted stock units would have been included in the denominator of diluted EPS.
