The fair values of cash, accounts receivable, accounts payable, and accrued liabilities approximated their carrying values as of December 31, 2022 and 2021, due to their short-term nature. All other financial instruments, except for earn-out liabilities, are valued either based on recent trades of securities in active markets or based on quoted market prices of similar instruments and other significant inputs derived from or corroborated by observable market data. During the years ended December 31, 2022, 2021, and 2020, the Company had no transfers between levels of the fair value hierarchy of its assets or liabilities measured at fair value.

As of December 31, 2022 and 2021, the long-term earn-out liability, which is solely related to the acquisition of HHL, is classified as a Level 3 fair value measurement containing significant unobservable inputs including estimates of achieving certain revenue targets. At inception, the fair value of the earn-out liability associated with the HHL acquisition was determined based on revenue projections and probability of achievement of revenue targets as evaluated using a Monte Carlo simulation. The following assumptions were used to determine the fair value at inception:

	HHL
Revenue risk-adjusted discount rate	9.1	%
Revenue volatility	50.0	%
Counterparty discount rate	5.0	%

The fair value of the earn-out liability is remeasured at each reporting period. This change in fair value is related to contingent consideration and compensation costs (see Note 14 – Stockholders’ Equity) and is recognized in other income (expense) and general and administrative expenses, respectively, on the consolidated statements of operations and comprehensive loss. The change in the fair value of earn-out liabilities is as follows (in thousands):

Balance at December 31, 2020	$	—
HHL acquisition	1,208
Apostrophe acquisition	32,650
Change in fair value due to revaluation and service-based vesting	10,975
Reclassification to earn-out payable	(42,834)
Balance at December 31, 2021	1,999
Change in fair value due to revaluation and service-based vesting	976
Balance at December 31, 2022	$	2,975
