Risks and Uncertainties [Abstract]
Financial Risk Management	Financial Risk Management Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents, marketable securities, restricted cash, and accounts and accrued receivable. Cash and cash equivalents, marketable securities, and restricted cash are invested with the primary objective being the preservation of capital and maintenance of liquidity. The guidelines on the diversification of the marketable securities portfolio and credit quality of financial instruments that the Company holds minimizes the exposure to concentration of credit risk. The Company further limits its exposure to credit loss by placing its cash and cash equivalents with multiple high credit quality financial institutions. The Company’s exposure to credit risk for accounts and accrued receivables is indicated by the carrying value of its accounts receivable and accrued receivables. We review our trade receivables and accrued revenue, and reserve for amounts if collectability is no longer reasonably assured based on an assessment of various factors including historical loss rates and expectations of forward-looking loss estimates. Any adjustments made to our historical loss experience reflect current differences in asset-specific risk characteristics and current economic conditions. At December 31, 2024 and 2025, accounts and accrued receivable amounts were due from 16 and 7 customers, respectively. Interest Rate Risk The Company’s exposure to interest rate risk is primarily attributable to its cash and cash equivalents, restricted cash, marketable securities, and long-term operating lease liability. As of December 31, 2025, the Company had cash and cash equivalents of $128.5 million, restricted cash of $26.7 million, and marketable securities of $405.3 million, a majority of which was maintained in high credit quality and liquid bank accounts, term deposits, and held-for-trading marketable securities. The Company’s interest rate risk is affected by changes in the general level of interest rates, particularly because the majority of the Company’s investments are short-term in nature. Due to interest rates available to the Company, the short-term duration of the Company’s cash and cash equivalent holdings and marketable securities, and the low risk profile of the marketable securities, a 100 basis points change in interest rates would not have a material effect on the fair market value of cash, cash equivalents, restricted cash, and marketable securities. The Company also has the ability to hold the marketable securities until maturity, and therefore, the Company would not expect the Company’s operating results or cash flows to be affected to any significant degree by the effect of a sudden change in market interest rates. The Company does not enter into investments for speculative purposes and has not used any derivative financial instruments to manage interest rate exposure. The Company is further exposed to the risk that the fair value of the operating lease liability will vary as a result of changes in market interest rates. In order to manage funding needs or capital structure goals, the Company may enter into arrangements that are subject to either fixed market interest rates set at the time of issue or floating rates determined by ongoing market conditions. Debt subject to variable interest rates exposes the Company to variability in interest expense, while debt subject to fixed interest rates exposes the Company to variability in the fair value of debt. To manage interest rate exposure, the Company may access various sources of financing and manages borrowings in line with debt ratings, liquidity needs, maturity schedule, and currency and interest rate profiles. Foreign Currency Risk The Company holds cash primarily in U.S. and Canadian dollars. The Company had Canadian denominated cash and cash equivalents of CAD $55.6 million and CAD $61.8 million as of December 31, 2024 and 2025, respectively. The Company incurs certain operating expenses, makes capital project investments, and carries accounts payable in currencies other than the U.S. dollar, primarily in Canadian dollars, and the functional currency of the Dayhu JV and Beedie JV is the Canadian dollar. Accordingly, the Company is subject to foreign exchange risk due to fluctuations in exchange rates. The Company does not use derivative instruments to hedge exposure to foreign exchange risk. The operating results and financial position of the Company are reported in U.S. dollars in the Company’s consolidated financial statements. The fluctuation of the U.S. dollar relative to the Canadian dollar will have an impact on the reported balances for net assets, net earnings and shareholders’ equity in the Company’s consolidated financial statements.
