Earnings Per Share

The following table sets forth the computation of basic and diluted earnings per share:



	For the Year Ended December 31,
	2018			2017			2016
Numerator:
Net loss	$	(64,246	)	$	(77,926	)	$	(75,225	)
Denominator:
Weighted average shares (basic)	34,465			31,627			30,395
Dilutive effect of stock options, restricted stock units and stock appreciation rights	—			—			—
Weighted average shares (diluted)	34,465			31,627			30,395
Basic earnings per share	$	(1.86	)	$	(2.46	)	$	(2.47	)
Diluted earnings per share	$	(1.86	)	$	(2.46	)	$	(2.47	)

Dilutive potential common shares consist of shares issuable upon the exercise of stock options, settlement of SARs, and the vesting of RSUs and MSUs. Potential common shares determined to be antidilutive and excluded from diluted weighted average shares outstanding were approximately 2.1 million, 2.0 million and 1.8 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Since the Company has the intention and ability to settle the principal amount of its Notes (see Note 15) in cash, the treasury stock method is expected to be used for calculating any potential dilutive effect of the conversion spread on diluted net income per share, if applicable. The conversion spread will have a dilutive impact on diluted net income per share of common stock when the average market price of common stock for a given period exceeds the conversion price of $33.79 and $48.63 per share, for the 2019 Notes and 2047 Notes, respectively, and when the Company has net income.
