Net income (loss) per ordinary share

The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net income (loss) per share:

($ in thousands)	2018		2017			2016
Numerator:
Income (loss) from continuing operations	$	12,505	$	(33,226	)	$	(21,578	)

Net income (loss)	$	120,779	$	(32,885	)	$	(22,349	)
Denominator:
Weighted-average ordinary shares outstanding-basic		25,982,809		23,757,902			22,353,713

Weighted-average ordinary shares outstanding-diluted		26,397,875		23,757,902			22,353,713

The following numbers of outstanding ordinary share options, restricted shares and RSUs were excluded from the computation of diluted net loss per share for the periods with a net loss because their effect would have been anti-dilutive:

	Year ended December 31,
	2018		2017		2016
Options to purchase ordinary shares		—		878,242		1,065,655
