3. FAIR VALUE OF FINANCIAL INSTRUMENTS

U.S. GAAP defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price) and establishes a fair-value hierarchy that prioritizes the inputs used to measure fair value using the following definitions (from highest to lowest priority):

●

Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

●

Level 2 — Observable inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data by correlation or other means.

●

Level 3 — Prices or valuation techniques requiring inputs that are both significant to the fair-value measurement and unobservable.

Financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used in such measurements by major security type as of March 31, 2023 and December 31, 2022 are presented in the following table:


Fair value at March 31, 2023
	Total		Level 1		Level 2		Level 3
Assets:
Money market funds	$	3,855	$	3,855	$	—	$	—

Assets:
Money market funds	$	5,216	$	5,216	$	—	$	—

Money market funds and U.S. Treasury notes are valued at cost, which approximates fair value. These amounts are included on the balance sheet in cash and cash equivalents at March 31, 2023 and December 31, 2022.
