  (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 December 31, 2017 and June 30, 2018, substantially all of the Company’s cash and cash equivalents were held by major financial institutions located in the PRC, which management believes are of high credit quality.

For the credit risk related to trade accounts receivable, the Company performs ongoing credit evaluations of its customers and, if necessary, maintains reserves for potential credit losses. Historically, such losses have been within management’s expectations.
