FAIR VALUE MEASUREMENT

11. FAIR VALUE MEASUREMENT

Measured or disclosed at fair value on a recurring basis

The Group measured its financial assets and liabilities, including cash and cash equivalents, restricted cash and convertible notes at fair value on a recurring basis as of December 31, 2020 and June 30, 2021. Cash and cash equivalents and restricted cash are classified within Level 1 of the fair value hierarchy because they are valued based on the quoted market price in an active market. The Group determines the fair value of convertible notes, with the assistance of an independent third-party appraiser, based on Level 3 inputs. To determine the fair value of the convertible notes, the Group used probability expected return method.

The key assumptions used in valuation of convertible notes as of June 30, 2021 are summarized in the table below:

Probability for Conversion

 

90%

Probability for Redemption

 

10%

Remaining life

 

0.1 – 2.5 years
