13. LOSS PER SHARE

Basic loss per ordinary share is calculated based upon net loss available to holders of ordinary shares divided by the weighted average number of shares outstanding. For the three and nine months ended September 30, 2015 and 2014, as the Company was in a net loss position, the diluted loss per share does not assume conversion or exercise of stock options and awards as they would have an anti-dilutive effect on loss per share. Therefore, the weighted average number of basic and diluted voting shares of ordinary shares outstanding for the three and nine months ended September 30, 2015 and 2014 was as follows:


	Three Months Ended				Nine Months Ended
	September 30,				September 30,
(In thousands)	2015		2014		2015		2014
Weighted average number of ordinary shares outstanding		149,512		145,896		148,828		144,732

The following potential ordinary equivalent shares have not been included in the net loss per ordinary share calculation because the effect would have been anti-dilutive:


	Three Months Ended					Nine Months Ended
	September 30,				September 30,
(In thousands)	2015		2014		2015		2014
Stock options		9,539		9,721		9,110		9,605
Restricted stock units		1,482		1,683		1,838		1,821
Total		11,021		11,404		10,948		11,426
