23.	Concentration of risk

Credit risk

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents, accounts receivable and other receivables. As of

June 30, 2018,

43%

of the Company’s cash and cash equivalents were held by major financial institutions located in Mainland China, the remaining

57%

was held by a financial institution located in the United States of America. The Company believes that these financial institutions located in Mainland China and the United States of America are of high credit quality. For accounts receivable and other receivables, the Company extends credit based on an evaluation of the customer’s or other

third

parties’ financial condition, generally without requiring collateral or other security. In order to minimize the credit risk, the Company delegated a team responsible for credit approvals and other monitoring procedures to ensure that follow-up action is taken to recover overdue debts. Further, the Company reviews the recoverable amount of each individual receivable at each balance sheet date to ensure that adequate allowances are made for doubtful accounts. In this regard, the Company considers that the Company’s credit risk for accounts receivable and other receivables is significantly reduced.

Risk arising from operations in foreign countries

All of the Company’s operations are conducted within the PRC. The Company’s operations in the PRC are subject to various political, economic, and other risks and uncertainties inherent in the PRC. Among other risks, the Company’s operations in the PRC are subject to the risks of restrictions on transfer of funds, changing taxation policies, foreign exchange restrictions; and political conditions and governmental regulations.

Currency convertibility risk

Significant part of the Company’s businesses is transacted in Renminbi, which is

not

freely convertible into foreign currencies. All foreign exchange transactions take place either through the People’s Bank of China or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the People’s Bank of China. Approval of foreign currency payments by the People’s Bank of China or other regulatory institutions requires submitting a payment application form together with suppliers’ invoices and signed contracts. These exchange control measures imposed by the PRC government authorities

may

restrict the ability of the Company’s PRC subsidiaries and VIEs to transfer its net assets, which to the Company through loans, advances or cash dividends.
