Fair Value Measurements

14. Fair Value Measurements

Financial assets and liabilities and nonfinancial assets and liabilities are measured at fair value on a recurring basis under a framework of a fair value hierarchy which prioritizes the inputs into valuation techniques used to measure fair value into three broad levels. This hierarchy gives the highest priority to quoted prices (unadjusted) in active markets and the lowest priority to unobservable inputs. Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement. The three levels of the fair value hierarchy per ASC Topic 820 are as follows:

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

Level 2: Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data.

Level 3: Unobservable inputs due to the fact that there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability.

The following table summarizes the Company’s financial assets and liabilities measured on a recurring basis at fair value by respective level of the fair value hierarchy:

	Level 1		Level 2		Level 3		Total

Short-term investments		20		—		—		20

The Company’s cash equivalents, comprised principally of U.S. treasury securities, are classified within Level 1 of the fair value hierarchy.

The Company’s short-term investments consist of the 200,000 shares of common stock of Fabled and 20,000 shares of Fabled Copper Corp. and are classified within Level 1 of the fair value hierarchy (see Note 5).

At December 31, 2023 and 2022, the Company did not have any financial assets or liabilities classified within Level 2 or Level 3 of the fair value hierarchy.

Non-recurring Fair Value Measurements

The Company recorded a change in estimate to its ARO as of December 31, 2023, of approximately $44,000 (see Note 12), reflecting a change in the fair value of the ARO primarily as the result of changes in assumptions related to the amount and timing of future expenditures used in the determination of future cash flows, the change in inflation assumptions, and the change in the discount rate, following the guidance of ASC Topic 410. The fair value analysis was performed internally by the Company. The valuation falls within Level 3 of the fair value hierarchy.

No other non-recurring fair value adjustments to liabilities or long-lived assets were recorded during the years ended December 31, 2023 and 2022.
