14. FAIR VALUE MEASUREMENTS

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The fair values of common stock warrants were measured using the Black-Scholes Model (see Note 23). Inputs used to determine estimated fair value of the warrant liabilities include the estimated fair value of the underlying stock at the valuation date, the estimated term of the warrants, risk-free interest rates, expected dividends and the expected volatility of the underlying stock. The significant unobservable inputs used in the fair value measurement of the warrant liability are the fair value of the underlying stock at the valuation date and the estimated term of the warrants. The fair value of convertible note is based on a discounted cash flow model with an unobservable input of discount rate. (Level 3)

In 2015, the Group issued warrants in connection with its convertible notes. The warrants are recorded at fair market value at the date of issuance and subsequently at each reporting date. The following table presents the change in the warrants liability that were measured at fair value on a recurring basis using significant Level 3 inputs during 2018 and 2019 (see Note 20).
