Equity investments using the measurement alternative The Group did not disclose the fair value of alternative measure method investments if it is not practicable to estimate the fair value of its alternative measure method investments for which a quoted market price is not available due to both excessive cost as well as lack of available information on fair value of such investments. Specifically, many of the investees are start-up companies in China and operate in emerging industries for which the Group has not been able to estimate their fair values. For those equity investments having observable price changes in orderly transactions for the identical or similar investments of the same issuers, the Group would disclose the fair value of the alternative measure method investments.
