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.

The carrying value of our revolving credit facility (Note 8) approximates fair value as of December 31, 2025 and is measured using Level 2 inputs.
The fair value of the convertible debt securities due from Bear Creek was determined using binomial lattice models based on the contractual terms and relevant inputs including the risk free interest rate, the USD to CAD currency swap rate, expected dividend yield, expected volatility and the discount yield which are observable in active markets. The use of reasonably possible alternative assumptions would not significantly impact our results.
As of December 31, 2025, 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, equity method investments 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.

About Fair Value Disclosures

Fair value disclosures classify all assets and liabilities measured at fair value into a three-level hierarchy: Level 1 (quoted market prices), Level 2 (observable inputs like yield curves), and Level 3 (unobservable inputs requiring management estimates). The proportion of Level 3 assets directly reflects how much of the balance sheet depends on internal models rather than market evidence.

Key signals: a growing Level 3 balance relative to total fair-value assets increases valuation uncertainty and earnings volatility risk. Watch for transfers between levels — assets moving from Level 2 to Level 3 often signal deteriorating market liquidity. Unrealized gains and losses on Level 3 positions flow through earnings or other comprehensive income, so large swings deserve scrutiny. For financial institutions, examine the sensitivity disclosures that show how Level 3 valuations change under alternative assumptions. Compare the fair value of debt against its carrying amount to gauge hidden leverage.
