FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS

The accounting standard for fair value measurements provides a framework for measuring fair value and requires expanded disclosures regarding fair value measurements. Fair value is defined as the price that would be received for an asset or the “exit price” that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between independent market participants on the measurement date. The Company measures financial assets and liabilities at fair value at each reporting period using a fair value hierarchy, which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. This hierarchy prioritizes the inputs into three broad levels as follows:

•Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities.

•Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

•Level 3—Inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. Factors used to develop the estimated fair value are unobservable inputs that are not supported by market activity. The sensitivity of the fair value measurement to changes in unobservable inputs may result in a significantly higher or lower measurement.

Cash, cash equivalents and investments are reported at their respective fair values on the Company's consolidated balance sheets. The Company's short-term and long-term investments are classified as available-for-sale securities.

The following table sets forth the Company’s financial assets subject to fair value measurements on a recurring basis by level within the fair value hierarchy as of March 31, 2023 and December 31, 2022 (in thousands):

During the three months ended March 31, 2023 and 2022, there were immaterial and no realized gains or losses on the sale of available-for-sale securities, respectively. Accrued interest receivable excluded from both the fair value and amortized cost basis of the available-for-sale securities was $5.8 million and $7.5 million as of March 31, 2023 and December 31, 2022, respectively, and was recorded in other current assets on our condensed consolidated balance sheets. As of March 31, 2023 and December 31, 2022, no allowance for credit losses was recorded related to an impairment of available-for-sale securities.

The following table summarizes our available-for-sale securities by contractual maturity:


	March 31, 2023
	Amortized cost		Estimated Fair Value
Within one year	$	2,083,917	$	2,078,377
After one year through three years	443,723		441,727
Total	$	2,527,640	$	2,520,104

Level 3 liabilities consist of common stock warrant liability of which the fair value was measured upon issuance and is remeasured at each reporting date. Level 3 liabilities also consist of residual value guarantee liabilities, of which the fair value measurement is nonrecurring and measured upon delivery of vehicles. The valuation methodology and underlying assumptions are discussed further in Note 2 “Summary of Significant Accounting Policies” and Note 7 “Common Stock Warrant Liability”. Significant increases (decreases) in the unobservable inputs used in determining the fair value would result in a significantly higher (lower) fair value measurement. The following table presents a reconciliation of the common stock warrant liability measured and recorded at fair value on a recurring basis (in thousands):


	Three Months Ended March 31,
	2023		2022
Fair value-beginning of period	$	140,590	$	1,394,808
Change in fair value	40,802		(523,330)
Fair value-end of period	$	181,392	$	871,478
