13. Subsequent Event

On August 27, 2013, upon recommendation by the Company’s compensation committee, the Company’s board of directors granted awards of restricted stock units (“RSU”) covering a total of 1,057,360 ordinary shares that vest based on service conditions and a total of 154,500 ordinary shares that vest based on a combination of service and performance conditions. The fair value on the grant date was $14.56 per ordinary share. Pursuant to the terms of the service condition awards, 1/16th of the RSUs shall vest each 3 months following the vesting commencement date, so as to be 100% vested on the fourth anniversary of the vesting commencement date. Pursuant to the terms of the performance condition awards, 1/8th of the RSUs shall vest each 3 months following the vesting commencement date, so as to be 100% vested on the second anniversary of the vesting commencement date; provided, however, that notwithstanding the foregoing, the RSUs shall not vest at all until the performance conditions are achieved and are subject to the RSU holder continuing to provide services to the Company through such vesting dates. The vesting commencement date for the performance condition RSUs will begin upon achievement of financial targets for the fiscal year 2014. The performance condition RSUs shall automatically be forfeited in their entirety, without any cost to or action by the Company, if there has been no achievement of the fiscal year 2014 financial targets.
