CONCENTRATIONS

(a)

Dependence on Mobile Operator

The revenue of the Company is primarily derived from cooperative arrangements with the Mobile Operator in the PRC. The major operators cooperated with the Company are China Mobile, China Unicom and China Telecom. If the strategic relationship with the Mobile Operator in the PRC is terminated or scaled-back, or if the Mobile Operator alters the revenue sharing arrangements, the Company's WVAS business would be adversely affected.

The following table shows the revenues and percentage of total revenues derived from those operators for the years ended December 31, 2013, 2014 and 2015:
