Fair Value Measurement |
Fair Value Measurement | 18. Fair Value Measurement ​ Fair value accounting establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: ​
Level 1 | Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
​
Level 2 | Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and
​
Level 3 | Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).
​ As required by accounting guidance, assets are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following table sets forth certain of the Company’s assets measured at fair value by level within the fair value hierarchy as of September 30, 2021 and December 31, 2020: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

Cash and cash equivalents | ​ | $ | 29,544 | ​ | $ | 25,405 | ​ | Level 1
Gold and silver rounds/bullion | ​ | $ | 559 | ​ | $ | 671 | ​ | Level 1
Accounts receivable, net | ​ | $ | 4,947 | ​ | $ | 4,226 | ​ | Level 2
Derivative liability - zinc zero cost collar | ​ | $ | (144) | ​ | $ | - | ​ | Level 2
​ Cash and cash equivalents consist primarily of cash deposits and are valued at cost, which approximates fair value. Gold and silver rounds/bullion consist of precious metals which are valued using quoted market prices. Please see Note 5 for additional information. ​ Accounts receivable, net include amounts due to the Company for deliveries of concentrates and doré sold to customers, net of embedded derivatives mark-to-market value of $0.1 million as of September 30, 2021, and $0.2 million as of December 31, 2020. Concentrate sales contracts provide for provisional pricing as specified in such contracts. These sales contain an embedded derivative related to the provisional pricing mechanism and are accounted for as a derivative. At the end of each reporting period, the Company records an adjustment to sales to reflect the mark-to-market of outstanding provisional invoices based on the forward price curve. Because these provisionally priced sales have not yet settled as of the reporting date, the mark-to-market adjustment related to these invoices is included in accounts receivable as of each reporting date and included in its accounts receivable on the accompanying Condensed Consolidated Interim Balance Sheets related to mark-to-market adjustments. Please see Note 13 for additional information. ​ Gains and losses related to changes in the fair value of these financial instruments were included in the Company’s Condensed Consolidated Interim Statements of Operations as shown in the following table: ​
