The following table presents a reconciliation of the weighted average shares outstanding used in calculating basic and diluted net loss per share as well as the calculation of basic and diluted net loss per share:

	Three Months Ended June 30,						Six Months Ended June 30,
(in thousands, except per share amounts)	2019			2018			2019			2018
Numerator (basic and diluted)
Net loss allocated to common shareholders for basic calculation	$	(97,836	)	$	(8,385	)	$	(132,410	)	$	(19,808	)
Denominator
Weighted average common shares outstanding, basic		46,824			41,044			46,762			40,074
Dilutive effect of RSUs1		—			—			—			—
Weighted average common shares outstanding, diluted		46,824			41,044			46,762			40,074
Net loss per share, basic	$	(2.09	)	$	(0.20	)	$	(2.83	)	$	(0.49	)
Net loss per share, diluted	$	(2.09	)	$	(0.20	)	$	(2.83	)	$	(0.49	)

¹Due to the net losses, RSUs representing approximately 375,000 and 398,000 for the three and six months ended June 30, 2019, respectively, and convertible notes and RSUs representing approximately 960,000 and 732,000 for the three and six months ended June 30, 2018, respectively, have been excluded from the number of shares used in calculating diluted net loss per share, as their inclusion would be antidilutive.
