Equity Incentive Plan

NOTE 6: EQUITY INCENTIVE PLAN

In September 2015, the Company adopted the 2015 Omnibus Incentive Plan (the “2015 Plan”). The 2015 Plan replaced the 2013 Share Option Plan.  Under the 2015 Plan, the Company can issue various types of equity compensation awards such as restricted shares, performance shares, restricted stock units, performance units, long-term cash award and other share-based awards.  

The options granted under the 2015 Plan generally have a four-year vesting period and expire ten years after the date of grant. Options granted under the 2015 Plan that are cancelled or forfeited before expiration become available for future grant.

As of September 30, 2016, 12,717,460 ordinary shares were available for grant under the 2015 Plan.  

A summary of the status of the Company’s option plans as of September 30, 2016 and changes during the period then ended is presented below:

In September 2015, the Company adopted an employee share purchase plan (“ESPP”) to encourage and enable eligible employees to acquire ownership of the Company’s ordinary shares purchased through accumulated payroll deductions on an after-tax basis. In the United States, the ESPP is intended to be an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code and the provisions of the ESPP will be construed in a manner consistent with the requirements of such section. The Company began its offerings under the ESPP on August 1, 2016.  As of September 30, 2016, 1,667,785 ordinary shares were available to be purchased by eligible employees under the ESPP and no shares had been issued under the ESPP.

The fair value of equity-based awards was estimated using the Black-Scholes option-pricing model for all grants with the following underlying assumptions: 

	Nine months ended September 30,					Year ended December 31,
