SHARE-BASED COMPENSATION

Historically, the Company's primary plan used for granting equity compensation awards was the 2010 Equity Incentive Plan (the "2010 Plan"). Effective August 15, 2017, awards are granted under the Company's 2017 Equity Incentive Plan (the "2017 Plan"), which was approved by the Company's shareholders at the 2017 Annual General Meeting of Shareholders. For further discussion on this 2017 Plan, refer to the Company's Proxy Statement, which was filed with the Securities and Exchange Commission on July 5, 2017.

The following table summarizes the Company’s share-based compensation expense:



	Three-Month Periods Ended				Nine-Month Periods Ended
	December 31, 2017		December 31, 2016		December 31, 2017		December 31, 2016
	(In thousands)
Cost of sales	$	5,358	$	2,437	$	13,662	$	7,506
Selling, general and administrative expenses	15,400		18,344		49,356		59,805
Total share-based compensation expense	$	20,758	$	20,781	$	63,018	$	67,311

Total unrecognized compensation expense related to share options under all plans was $8.9 million, and will be recognized over a weighted-average remaining vesting period of 2.2 years. As of December 31, 2017, the number of options outstanding and exercisable under all plans was 1.4 million and 0.5 million, respectively, at a weighted-average exercise price of $3.39 per share and $4.71 per share, respectively.

During the nine-month period ended December 31, 2017, the Company granted 6.0 million unvested share bonus awards. Of this amount, approximately 4.3 million unvested share bonus awards have an average grant date price of $16.45 per share and vest over four years. Further, approximately 0.6 million of these unvested shares represents the target amount of grants made to certain key employees whereby vesting is contingent on certain market conditions. The average grant date fair value of these awards contingent on certain market conditions was estimated to be $20.25 per award and was calculated using a Monte Carlo simulation. The number of shares contingent on market conditions that ultimately will vest will range from zero up to a maximum of 1.2 million based on a measurement of the percentile rank of the Company’s total shareholder return over a certain specified period against the Standard and Poor’s (“S&P”) 500 Composite Index and will cliff vest after a period of three years, if such market conditions have been met. Also, an immaterial amount of options and share bonus awards were granted by the Company during the nine-month period ended December 31, 2017 under an immaterial plan.

As of December 31, 2017, approximately 15.5 million unvested share bonus awards under all plans were outstanding, of which vesting for a targeted amount of 2.0 million is contingent primarily on meeting certain market conditions. The number of shares that will ultimately be issued can range from zero to 4.0 million based on the achievement levels of the respective conditions. During the nine-month period ended December 31, 2017, 1.4 million shares vested in connection with the share bonus awards with market conditions granted in fiscal year 2015.

As of December 31, 2017, total unrecognized compensation expense related to unvested share bonus awards under all plans was approximately $162.8 million, and will be recognized over a weighted-average remaining vesting period of 2.6 years.
