Full time employees of the Group in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, medical care, employee housing fund, unemployment insurance and other welfare benefits are provided to employees.

The Group has no legal obligation for the benefits beyond the contributions made. The total amounts for such employee benefits, which were expensed as incurred, were $7,391, $9,361 and $12,748 for the years ended December 31, 2015, 2016 and 2017, respectively.
