14.	FAIR VALUE

The accounting framework for determining fair value includes a hierarchy for ranking the quality and reliability of the information used to measure fair value, which enables the reader of the financial statements to assess the inputs used to develop those measurements. The fair value hierarchy consists of three tiers:

Level 1: Defined as quoted market prices in active markets for identical assets or liabilities.

Level 2: Defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, model-based valuation techniques for which all significant assumptions are observable in the market 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: Defined as unobservable inputs that are not corroborated by market data.

The Company measures the fair value of money market funds using Level 1 inputs. As of December 31, 2022, the Company has two treasury bills, one with a maturity date of three months or less, classified as cash equivalents. The second treasury bill has a maturity date greater than three months but less than a year and as a result is classified as a short-term investment. The treasury bills are valued using Level 1 inputs. Pricing sources may include industry standard data providers, security master files from large financial institutions and other third-party sources used to determine a daily market value.

The following table presents the fair value of the financial instruments measured on a recurring basis as of December 31, 2022.

	December 31, 2022
	Carrying		Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs
	Amount		(Level 1)		(Level 2)		(Level 3)		Total
Cash equivalents:
Money market fund	$	18,160	$	18,160	$	-	$	-	$	18,160
Treasury bill		10,383		10,383		-		-		10,383

Short-term investments:

Total cash equivalents and short-term investments	$	43,301	$	43,301	$	-	$	-	$	43,301

There were no financial instrumets measured on a recurring basis as of December 31, 2021.

The carrying amount of the Company’s financial instruments, including cash equivalents, short-term investments, prepaid expenses and other current assets, accrued expenses and other short-term liabilities approximate fair value due to the short-term nature of these items.
