Investments And Fair Value Instruments [Abstract]

Note 6. Investments and Fair Value Instruments

Investments

The investments are carried at fair value, based on quoted market prices or other readily available market information. Unrealized gains and losses are included in accumulated other comprehensive income, which is reflected as a separate component of stockholder’s equity in the consolidated balance sheets. Gains and losses are recognized when realized in the consolidated statements of operations and comprehensive loss.

The following tables summarize the amortized cost and fair value of the investment securities portfolio at December 31, 2023 and 2022:


(Dollars in thousands)	Amortized Cost		Unrealized Gains		Unrealized Losses		Estimated Fair Value
December 31, 2023
Cash equivalents:
Money market funds	$	4,925	$	—	$	—	$	4,925
Short-term investments:

The Company uses the market approach technique to value its financial instruments and there were no changes in valuation techniques during 2023 or 2022. The Company’s financial instruments consist primarily of cash and cash equivalents, short-term investments, accounts receivable and other receivables, accounts payable and accrued liabilities. For short-term investments, accounts receivable and other receivables, accounts payable and accrued liabilities, the carrying amounts of these financial instruments as of December 31, 2023 and December 31, 2022 were considered representative of their fair values due to their short term to maturity or repayment. Cash equivalents are carried at cost, which approximates their fair value.

The Company’s Level 3 liabilities consist of a contingent liability resulting from the Anawah, Inc. ("Anawah") acquisition as described in Note 13, as well as preferred investment options related to the March 2023 Private Placement and August 2022 Registered Direct offerings discussed in Note 10.

The contingent liability related to the Anawah acquisition was measured and recorded on a recurring basis as of December 31, 2023 and 2022, using unobservable inputs, namely the Company’s ability and intent to pursue certain specific products developed using technology acquired in the purchase. A significant deviation in the Company’s ability and/or intent to pursue the technology acquired in the purchase could result in a significantly lower (higher) fair value measurement.

The preferred investment option liabilities were measured and recorded on a recurring basis using the Black-Scholes Model with the following assumptions at December 31, 2023 and 2022:


	March 2023 Options - Series A & March 2023 Placement Agent Options					March 2023 Options - Series B					August 2022 Options & August 2022 Placement Agent Options
	December 31, 2023			December 31, 2022		December 31, 2023			December 31, 2022		December 31, 2023			December 31, 2022
Remaining term (in years)		4.16			—		0.61			—		3.67			4.67
Expected volatility		91.7	%		—		78.7	%		—		90.5	%		106.2	%
Risk-free interest rate		3.9	%		—		5.2	%		—		4.0	%		4.0	%
Expected dividend yield		0	%		—		0	%		—		0	%		0	%

The significant unobservable input used in the fair value measurement of the Company’s Level 3 warrant liabilities is volatility. A significant increase (decrease) in volatility could result in a significantly higher (lower) fair value measurement.

The following table sets forth the establishment of the Company’s Level 3 liabilities, as well as a summary of the changes in the fair value and other adjustments (in thousands):


(Dollars in thousands)	March 2023 Options - Series A			March 2023 Options - Series B			March 2023 Placement Agent Options			August 2022 Options			August 2022 Placement Agent Options			Contingent Liabilities		Total
Balance as of December 31, 2022	$	—		$	—		$	—		$	767		$	39		$	2,000	$	2,806
Initial recognition		4,324			2,274			212			—			—			—		6,810
Change in fair value and other adjustments		(3,316	)		(2,233	)		(166	)		(608	)		(36	)		—		(6,359	)

Assets classified as held for sale are recorded at fair value as of December 31, 2023 and 2022. The Company has classified the fair value measurements as a Level 3 measurement in the fair value hierarchy as the fair value has been estimated using publicly available prices for some of the assets, and business partners' estimates for assets with prices not readily available, due to the relatively small size of the industry in which they can be used.
