ASC 820-10, Fair Value Measurements and Disclosures: Overall , establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets Level 2 — Include other inputs that are directly or indirectly observable in the marketplace Level 3 — Unobservable inputs which are supported by little or no market activity ASC 820-10 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset. Assets and liabilities measured or disclosed at fair value The Company measures bifurcated embedded redemption feature derivative of convertible notes at fair value on a recurring basis, which is classified within Level 3 as the fair value is measured based on risk-free interest rate, volatility, mature date, conversion price, and other factors. There are no derivative liabilities as of December 31, 2020 and 2021, respectively. For further information on the convertible notes see Note 13. The Company measures derivative assets at fair value on a recurring basis. The derivative assets are classified within Level 2 as the fair value is measured by using inputs derived from or corroborated by observable market data. The Company had RMB100 and RMB5,989 (US$940) of derivative asset s as of December 31, 2020 and 2021 respectively. The Company’s non-financial long-lived assets, such as intangible assets and property and equipment, would be measured at fair value only if they were determined to be impaired. Company uses a combination of valuation methodologies, including market approach based on the Company’s best estimate to determine the fair value of these non-financial assets. The Company measures non-recurring fair value measurements as of the observable transaction dates. The fair value (Level 2) was evaluated for certain property and equipment based on quoted prices for similar assets in markets that are not active. For equity investments accounted for under the measurement alternative, when there are observable price changes in orderly transactions for identical or similar investments of the same issuer, the investments are re-measured to fair value (Note 7). The non-recurring fair value measurements to the carrying amount of an investment usually requires management to estimate a price adjustment for the different rights and obligations between a similar instrument of the same issuer with an observable price change in an orderly transaction and the investment held by the Company. These non-recurring fair value measurements were measured as of the observable transaction dates. The valuation methodologies involved require management to use the observable transaction price at the transaction date and other unobservable inputs (level 3) such as volatility of comparable companies and probability of exit events as it relates to liquidation, redemption preferences and qualified IPO. The Company measures certain financial assets, including equity securities accounted for at fair value using measurement alternative at fair value on a non-recurring basis only if an impairment loss or upward valuation were to be recognized. For the year ended December 31, 2020, assets measured at fair value are summarized below:
