During 2022, the valuation allowance increased primarily due to the addition of deferred tax assets related to current year net operating losses. During 2021, the valuation allowance decreased primarily due to the expiration of capital loss carryovers. At December 31, 2022, Solitario has unused US Federal net operating loss carryovers of $22,905,000 and unused US State net operating loss carryovers of $24,811,000 which begin expiring in 2027. As a result of the ownership change of Zazu Metals (Alaska) Corp, utilization of some of these federal and state losses will be limited due to the annual limitation provided by Section 382 of the Internal Revenue Code. Solitario has unused capital loss carryovers of $380,000 for US Federal and US State purposes which begin expiring in 2025. Solitario has Canadian loss carryforwards of $9,294,000 which begin expiring in 2027. Other foreign loss carryforwards for which Solitario has provided a full valuation allowance related to Solitario’s exploration activities in Peru. The Peru losses do not expire. Solitario adopted ASC 740, which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 requires that Solitario recognize in its consolidated financial statements only those tax positions that are “more-likely-than-not” of being sustained as of the adoption date, based on the technical merits of the position. As a result of the implementation of ASC 740, Solitario performed a comprehensive review of its material tax positions in accordance with recognition and measurement standards established by ASC 740. The provisions of ASC 740 had no effect on Solitario’s financial position, cash flows or results of operations at December 31, 2022 or December 31, 2021, or for the years then ended as Solitario had no unrecognized tax benefits. Solitario and its subsidiaries are subject to the following material taxing jurisdictions: United States Federal, State of Colorado, State of Alaska, State of South Dakota, Canada and Peru. Solitario’s United States federal, Canada and State of Alaska returns for years 2019 and forward and Solitario’s Peru and State of Colorado returns for tax years 2018 and forward are subject to examination. Solitario’s policy is to recognize interest and penalties related to uncertain tax benefits in income tax expense. Solitario has no accrued interest or penalties related to uncertain tax positions as of December 31, 2022, or December 31, 2021 or for the years then ended.
