Note:
The investments were issued by commercial banks in the PRC with a variable interest rate indexed to performance of underlying assets. Since these investments’ maturity dates are within one year, they are classified as short-term investments.
 
Time deposits and investments in financial instruments are stated on the balance sheet at the principal amount plus accrued interest. Interest income is recorded in “other income” in the statement of comprehensive income.
