| Recently Adopted and Issued Accounting Standards | Recently Adopted Accounting Standards The Company adopted Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures for the fiscal year ended March 31, 2025 for annual period information and applied the amendments retroactively to all comparative periods. The amendments to interim period information were applied for interim periods beginning April 1, 2025. Refer to Note 13 for additional information. Recently Issued Accounting Standards In December 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments enhance the transparency and decision usefulness of income tax disclosures, including jurisdictional information, by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disclosures. The amendments also eliminate certain disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. The amendments are effective for the Company for fiscal years beginning April 1, 2025. The Company is currently assessing the impact of this standard on the consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments address investor requests for more transparent information. The primary goal is to improve the decision usefulness of expense information on public business entities’ income statements through the disaggregation of relevant expense captions in the notes to the financial statements. The amendments are effective for the Company for fiscal years beginning April 1, 2027 and for interim periods beginning April 1, 2028. The Company is currently assessing the impact of this standard on the consolidated financial statements.

| Segment Reporting | The measure of segment profit or loss the CODM uses to assess segment performance and allocate resources is income before income taxes and the effect of valuation adjustments on derivative instruments and revaluations of foreign currency denominated debt. Since the Company does not elect to apply hedge accounting, the impact to earnings resulting from these valuation adjustments as reported under GAAP is not representative of segment performance as evaluated by the CODM. Realized gains and losses on derivative instruments, net of realized gains and losses on foreign currency denominated debt, are included in the measure of segment profit or loss when evaluating segment performance. No adjustments are made to segment performance to allocate any revenues or expenses. |
