Loss

Per Share

Our basic net loss per share amounts have been computed by dividing net loss by the weighted-average number of common shares outstanding during the period. For the

three

months ended

March 31, 2019

and

2018,

we reported net losses and, accordingly, potential common shares were

not

included since such inclusion would have been anti-dilutive.

The calculations of net loss per share, basic and diluted, are as follows (amounts in thousands, except per share data):

				Weighted-Average
				Shares
	Net Loss			Outstanding		Per Share
	(Numerator)			(Denominator)		Amount
Three months ended March 31, 2019
Basic and diluted	$	(18,735	)		84,542	$	(0.22	)
Three months ended March 31, 2018
Basic and diluted	$	(13,424	)		72,517	$	(0.19	)

The following table summarizes anti-dilutive common shares or common shares where performance conditions have

not

been met, that were excluded from the calculation of diluted net loss per share (in thousands):

	Three Months Ended March 31,
	2019		2018
Stock options		6,522		3,483
Contingent consideration liability (1)		2,565		2,359
Total securities excluded		9,087		5,842

(

Calculated as follows: (a) the contingent consideration liability balance divided by (b) the closing stock price of our common stock.
