During the three and six months ended March 31, 2012 and 2013, there were no other customers that individually comprised 10% or more of the Company’s net revenue.

(b) Credit Risk

Financial instruments that potentially subject the Company to a significant concentration of credit risk consist primarily of cash and cash equivalents and pledged deposits. As of September 30, 2012 and March 31, 2013, substantially all of the Company’s cash and cash equivalents and pledged deposits were held by major financial institutions located in the PRC, which management believes are of high credit quality.
