When available, the Group uses quoted market prices to determine the fair value of an asset or liability. If quoted market prices are not available, the Group will measure fair value using valuation techniques that use, when possible, current market-based or independently sourced market parameters, such as interest rates and currency rates. For short-term investments, which consists of wealth management products, the Group refers to the quoted rate of return provided by financial institutions at the end of each period using the discounted cash flow method. The Group classifies the valuation techniques as Level 2 of fair value measurement.
