Summary of significant accounting policies |
Summary of significant accounting policies | 2) Summary of significant accounting policies Basis of presentation These interim consolidated financial statements have been prepared using accounting principles generally accepted in the United States (“U.S. GAAP”) and include the accounts of Trilogy and its wholly owned subsidiaries, NovaCopper US Inc. (dba “Trilogy Metals US”) and 995 Exploration Inc. All intercompany transactions are eliminated on consolidation. For variable interest entities (“VIEs”) where Trilogy is not the primary beneficiary, we use the equity method of accounting. All figures are in United States dollars unless otherwise noted. References to CDN$ refer to amounts in Canadian dollars. These unaudited interim consolidated financial statements include all adjustments necessary for the fair presentation of the Company’s financial position as of May 31, 2022 and our results of operations and cash flows for the six months ended May 31, 2022 and May 31, 2021. The results of operations for the six months ended May 31, 2022 are not necessarily indicative of the results to be expected for the fiscal year ending November 30, 2022. As these interim consolidated financial statements do not contain all of the disclosures required by U.S. GAAP for annual financial statements, these unaudited interim consolidated financial statements should be read in conjunction with the annual financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended November 30, 2021, filed with the U.S. Securities and Exchange Commission (“SEC”) and Canadian securities regulatory authorities on February 11, 2022. These interim consolidated financial statements were approved by the Company’s Audit Committee on behalf of the Board of Directors for issue on July 5, 2022. Use of estimates and measurement uncertainties The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions of future events that affect the reported amount of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of expenditures during the period. Significant judgments include the assessment of potential indicators of impairment of mineral properties and investments in affiliates. Significant estimates include the measurement of the equity method investment, income taxes, and the valuation of stock-based compensation. Actual results could differ materially from those reported. Management assesses the possibility of impairment in the carrying value of its equity method investment in Ambler Metals whenever events or circumstances indicate that the carrying amount of the investment may not be recoverable. Significant judgments are made in assessing the possibility of impairment. Factors that may be indicative of an impairment include a loss in the value of an investment that is not temporary. Management considers several factors in considering if an indicator of impairment has occurred, including but not limited to, sustained losses by the investment, the absence of the ability to recover the carrying amount of the investment, significant changes in the legal, business or regulatory environment, significant adverse changes impacting the investee and internal reporting indicating the economic performance of an investment is, or will be, worse than expected. ​ These factors are subjective and require consideration at each period end. If an indicator of impairment is determined to exist, the fair value of the impaired investment is determined based on the valuation of cohort companies with similar projects or upon the present value of expected future cash flows using discount rates and other assumptions believed to be consistent with those used by principal market participants and observed market earnings multiples of comparable companies. ​ Management calculates the estimated undiscounted future net cash flows relating to the asset or asset group using estimated future prices, proven and probable reserves and other mineral resources, and operating, capital and reclamation costs. When the carrying value of an asset exceeds the related undiscounted cash flows, the asset is written down to its estimated fair value, which is usually determined using discounted future cash flows. Management’s estimates of mineral prices, mineral resources, foreign exchange rates, production levels operating, capital and reclamation costs are subject to risk and uncertainties that may affect the determination of the recoverability of the long-lived asset. It is possible that material changes could occur that may adversely affect management’s estimates.
