16. 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, Bridge Notes and warrant liability at fair value on a recurring basis as of December 31, 2021 and 2022. 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 fair value of the warrant liability and Bridge Notes are based on significant unobservable inputs, which represent Level 3 measurements within the fair value hierarchy. In determining the fair value of the warrant liability, the Company used the Monte Carlo Model that assumes optimal exercise of the Company’s redemption option at the earliest possible date. See Note 15.

As of December 31, 2021 and 2022, information about inputs for the fair value measurements of the Group’s assets and liabilities that are measured at fair value on a recurring basis in periods subsequent to their initial recognition is as follow:

The Group measured the long-lived assets using the income approach—discounted cash flow method, when events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable.
