[1] Long-term investments are measured at fair value which are estimated using the market approach, based on valuation multiples derived from comparable companies, adjusted for size and risk. The significant unobservable inputs used in the valuation include market multiples ranging from 0.83 to 10.70 and a discount for lack of marketability of 12.95%.
[2] Certain of the Company’s senior convertible notes and convertible promissory notes are accounted for under the fair value option election in ASC 825. Under the fair value option election, the financial instrument is initially measured at its issue-date estimated fair value and subsequently remeasured at estimated fair value on a recurring basis at each reporting period date. The estimated fair value adjustment is presented within other income (expense) in the unaudited condensed consolidated statements of operations and comprehensive loss. The fair value was estimated using a binomial option pricing model, which incorporates probability-weighted outcomes and considers the contractual terms of the instruments, including conversion features and settlement scenarios.
