| Foreign Currency Translation | Foreign Currency Translation The reporting currency of the Company is U.S. dollars (“US$”). The functional currency of the Company’s entities incorporated in Cayman Islands, BVI and Hong Kong generally is US$. The Company’s PRC subsidiaries generally determined their functional currency to be RMB. The determination of the respective functional currency is based on the criteria of ASC Topic 830, Foreign Currency Matters. Transactions denominated in currencies other than functional currency are translated into functional currency at the exchange rates quoted by authoritative banks prevailing at the dates of the transactions. Exchange gains and losses resulting from those foreign currency transactions denominated in a currency other than the functional currency are recorded as a component of operating expenses in the consolidated statements of income and comprehensive Income. The consolidated financial statements of the Company are translated from the functional currency into US$. Assets and liabilities denominated in foreign currencies are translated into US$ using the applicable exchange rates at the balance sheet date. Equity accounts other than earnings generated in current year are translated into US$ at the appropriate historical rates. Revenues, expenses, gains and losses are translated into US$ using the periodic average exchange rates. The resulting foreign currency translation adjustments are recorded in accumulated other comprehensive income as a component of shareholders’ equity. Cash flows are also translated at average translation rates for the periods; therefore, amounts reported on the statement of cash flows will not necessarily agree with changes in the corresponding balances on the consolidated balance sheets. The relevant exchange rates are listed below:
