20. SEGMENT INFORMATION

 

The Group's chief operating decision maker has been identified as the chief executive officer, who reviews consolidated results when making decisions about allocating resources and assessing performance of the Group. Following the further expansion of module business and entering into the wafer business in 2011, the Group operated and viewed its performance in three segments. However, on September 28, 2012, the module business was disposed. Therefore, only two segments remained in 2013, 2014 and 2015. Furthermore, the Group's chief operating decision maker is not provided with asset information by segment. As such, no asset information by segment is presented. The following tables summarized the Group's revenue and cost generated from different revenue streams. Substantially all of its revenues are derived in the PRC. The Group's long lived assets and operations are substantially all located in the PRC.

 

The following table summarizes the Group's revenue by segment:
