[1] In January 2011, Zhengduo Information acquired the remaining 49% equity interest of Juyan Network at a consideration of RMB approximately 3,500,000 (US$556,000). Subsequent to this acquisition, Juyan Network becomes a wholly-owned subsidiary of Zhengduo Information. This was accounted for as an equity transaction, where the difference between the fair value of the purchase consideration and the carrying amount of non-controlling interest of approximately RMB1,600,000 (US$ 254,000) was recorded as additional paid-in capital.
