FAIR VALUE MEASUREMENTS |
FAIR VALUE MEASUREMENTS | 10. FAIR VALUE MEASUREMENTS ​ Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, we utilize a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows: ​ Level 1: Quoted prices for identical instruments in active markets; ​ Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and ​ Level 3: Prices or valuation techniques requiring inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity). ​ The following table sets forth our financial assets measured at fair value on a recurring basis (at least annually) by level within the fair value hierarchy. ​

​ (1) Included in Other assets on our consolidated balance sheets. ​ Our marketable securities classified within Level 1 of the fair value hierarchy are valued using quoted market prices in active markets multiplied by the quantity of shares held. The TriStar Gold Inc. warrants (Note 3) classified within Level 2 of the fair value hierarchy are model-derived (Black-Scholes) valuations in which the significant inputs are observable in active markets. The carrying value of our revolving credit facility (Note 4) approximates fair value as of March 31, 2023. ​ As of March 31, 2023, we had assets that, under certain conditions, are subject to measurement at fair value on a non-recurring basis like those associated with stream and royalty interests, intangible assets and other long-lived assets. For these assets, measurement at fair value in periods subsequent to their initial recognition is applicable if any of these assets are determined to be impaired. If recognition of these assets at their fair value becomes necessary, such measurements will be determined utilizing Level 3 inputs.
