EMPLOYEE DEFINED CONTRIBUTION PLAN

16. EMPLOYEE DEFINED CONTRIBUTION PLAN

Full-time employees of the Company’s subsidiaries and its VIEs in the PRC participate in a government mandated defined contribution plan pursuant to which certain pension benefits, medical care, unemployment insurance, employee housing fund and other welfare benefits are provided to employees. Chinese labor regulations require that the subsidiaries, VIEs and VIE’s subsidiaries of the Company make contributions to the government for these benefits based on certain percentages of the employees’ salaries. The Group has no legal obligation for the benefits beyond the contributions made. The total amount for such employee benefits which are expensed as incurred were RMB251,536, RMB371,622 and RMB544,965 (US$79,262) for the years ended December 31, 2016, 2017 and 2018, respectively.
