3.Concentration and risks

 

Concentration of customers and suppliers

 

There are no customers or suppliers from whom revenues or purchases individually represent greater than 10% of the total revenues or the total purchases of the Group for the years ended December 31, 2012, 2013 and 2014.

 

Concentration of credit risk

 

Assets that potentially subject the Group to significant concentrations of credit risk primarily consist of cash and cash equivalents, restricted cash, accounts receivable and short-term investments. The maximum exposure of such assets to credit risk is their carrying amounts as of the balance sheet dates. As of December 31, 2013 and 2014, all of the Group’s cash and cash equivalents, restricted cash and short-term investments were held by major financial institutions located in the PRC and Hong Kong which management believes are of high credit quality. PRC does not have an official deposit insurance program, nor does it have an agency similar to the Federal Deposit Insurance Corporation (FDIC) in the United States. However, the Group believes that the risk of failure of any of these PRC banks is remote. Bank failure is uncommon in China and the Group believes that those Chinese banks that hold the Group’s cash and cash equivalents, restricted cash and short-term investments are financially sound based on public available information. Accounts receivable are typically unsecured and are derived from revenues earned from customers in the PRC. The risk with respect to accounts receivable is mitigated by credit evaluations the Group performs on its customers and its ongoing monitoring process of outstanding balances.

 

Currency convertibility risk

 

The PRC government imposes controls on the convertibility of RMB into foreign currencies. The Group’s cash and cash equivalents, restricted cash and short-term investments denominated in RMB that are subject to such government controls amounted to RMB9,865,714 and RMB9,054,762 as of December 31, 2013 and 2014, respectively. The value of RMB is subject to changes in the central government policies and to international economic and political developments affecting supply and demand in the PRC foreign exchange trading system market. In the PRC, certain foreign exchange transactions are required by law to be transacted only by authorized financial institutions at exchange rates set by the People’s Bank of China (the “PBOC”). Remittances in currencies other than RMB by the Group in the PRC must be processed through PBOC or other Chinese foreign exchange regulatory bodies which require certain supporting documentation in order to process the remittance.

 

Foreign currency exchange rate risk

 

From July 21, 2005, the RMB is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. While the international reaction to the RMB appreciation has generally been positive, there remains significant international pressure on the PRC government to adopt an even more flexible currency policy, which could result in a further and more significant fluctuation of the RMB against the U.S. dollar.
