Defined contribution plan
Full-time employees of the Company in the PRC participate in a government mandated defined contribution plan, pursuant to which certain pension benefits, medical care, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the PRC operating subsidiaries of the Company make contributions to the government for these benefits based on certain percentages of the employees’ salaries. Except for contributions mentioned above, the Company has no legal obligation for the benefits beyond the contributions made.
The total contributions made, which were expensed as incurred, were $1,125,097 and $754,663 for the six months ended June 30, 2017 and 2016, respectively, and $620,577 and $419,105 for the three months ended June 30, 2017 and 2016, respectively.
