(d) Tax Contingencies The Company is, from time to time, involved in various tax assessments arising in the ordinary course of business. The Company cannot reasonably predict the likelihood or outcome of these actions. The Company has recognized tax provisions with respect to current assessments received from the tax authorities in the various jurisdictions in which the Company operates, and from any uncertain tax positions identified. For those amounts recognized related to current tax assessments received, the provision is based on management's best estimate of the outcome of those assessments, based on the validity of the issues in the assessment, management's support for their position, and the expectation with respect to any negotiations to settle the assessment. Management re-evaluates the outstanding tax assessments regularly to update their estimates related to the outcome for those assessments taking into account the criteria above. Peru The Company was assessed $1.1 million (4.3 million Peruvian soles), including interest and penalties of $0.6 million (2.4 million Peruvian soles), for the 2010 tax year by SUNAT, the Peruvian tax authority, with respect to the deduction of certain losses arising from derivative instruments. The Company has applied to the Peruvian tax court to appeal the assessment. On January 22, 2019, the Peruvian tax court reaffirmed SUNAT’s position and denied the deduction. The Company believes the assessment is inconsistent with Peruvian tax law and that it is probable the Company will succeed on appeal through the Peruvian legal system. The Company has paid the disputed amount in full and has initiated proceedings through the Peruvian legal system to appeal the decision of the Peruvian tax court. As at December 31, 2022, the Company has recorded the amount paid of $1.1 million (4.3 million Peruvian soles) in other long-term assets, as the Company believes it is probable that the appeal will be successful (Note 9). Argentina On August 16, 2022, the Argentine Tax Authority (“AFIP”) published General Resolution No.5248/2022 (the “Resolution”) which established a one-time “windfall income tax prepayment” for companies that have obtained extraordinary income derived from the general increase in international prices. The Resolution was published by AFIP without prior notice. The windfall income tax prepayment applies to companies that meet certain income tax or net income tax (before the deduction of accumulated tax losses) thresholds for 2021 or 2022. The aggregate amount of the windfall income tax prepayment payable by Mansfield calculated in accordance with the Resolution is approximately $5.5 to $6.0 million. The windfall income tax prepayment was to be paid in three equal and consecutive monthly instalments, starting on October 22, 2022, and is payable in addition to income tax instalments currently being paid by corporate taxpayers on account of their income tax obligations. The windfall income tax prepayment is an advance payment of income taxes due to be paid in 2022. Based on the historical accumulated losses of Mansfield for fiscal 2021 which can be carried forward for 2022, Mansfield was not liable for income tax, and based upon current corporate income tax laws and the ability of the Company to deduct historical accumulated losses, it was projected that income tax would not be required to be paid for fiscal 2022. To protect Mansfield’s position from having to pay the windfall income tax prepayment as an advance income tax for 2022, which based on management’s projections is not payable, Mansfield applied to the Federal Court of Salta Province for a preliminary injunction to prevent the AFIP from issuing a demand or other similar measure for the collection of the Windfall Income Tax Prepayment.  On October 3, 2022, Mansfield was notified that the Court had granted the preliminary injunction. As a result, Mansfield did not pay any of the three instalments due in 2022. Mansfield also filed an administrative claim with the AFIP to challenge the constitutionality of the Resolution, which was rejected by AFIP on November 2, 2022. Mansfield has challenged the rejection of its administrative claim, by filing legal proceedings against the AFIP with the Federal Court. On February 15, 2023, the Federal Court granted Mansfield a preliminary injunction in these legal proceedings. (e) Other Contingencies The Company is subject to various investigations and other claims, legal, labor, and tax proceedings covering matters that arise in the ordinary course of business activities. Each of these matters is subject to various uncertainties, and it is possible that some of these matters may be resolved unfavorably for the Company. Certain conditions may exist as of the date these financial statements are issued that may result in a loss to the Company. None of these matters is expected to have a material effect on the results of operations or financial conditions of the Company.
