Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation Consolidated Condensed Financial Statements — In the opinion of the Company, the accompanying Consolidated Condensed Financial Statements reflect all adjustments necessary to state fairly the Company’s financial position, results of operations and cash flows for the interim periods presented. All such adjustments are of a normal recurring nature. Results for interim periods are not indicative of the results for the entire fiscal year, particularly given the significant seasonality to the Company’s operating cycle. The accompanying Consolidated Condensed Financial Statements should be read in conjunction with the audited Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2023. Certain information and footnote disclosures, including significant accounting policies, normally included in fiscal year financial statements prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) have been condensed or omitted. The Consolidated Condensed Balance Sheet as of July 31, 2023 was derived from audited financial statements. Use of Estimates — The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the balance sheet date and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Fair Value of Financial Instruments — The estimated fair values of the 6.25% Notes and the 0.0% Convertible Notes (each as defined in Note 5, Long-Term Debt) are based on quoted market prices (a Level 2 input). The estimated fair value of the EPR Secured Notes and the NRP Loan (both as defined in Note 5, Long-Term Debt) have been estimated using analyses based on current borrowing rates for comparable debt instruments with similar maturity dates (a Level 2 input). The carrying values, including any unamortized premium or discount, and estimated fair values of the 6.25% Notes, 0.0% Convertible Notes, EPR Secured Notes and NRP Loan as of April 30, 2024 are presented below (in thousands):

0.0% Convertible Notes | $ | 575,000 |  |  | $ | 522,600 |

Accounting Standards Update and Change in Accounting Principle [Text Block] | Recently Issued Accounting Standards Standards Being Evaluated In November 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which is intended to improve reportable segment disclosures, primarily through incorporating enhanced segment disclosure requirements set forth by the Securities and Exchange Commission into U.S. GAAP. The enhanced disclosures will primarily require public entities to include specific disclosures regarding “significant expenses” that are regularly provided to or easily computed from information provided to the chief operating decision maker (“CODM”) and included within segment profit and loss. This ASU also requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 (the Company’s fiscal year ending July 31, 2025), and interim periods within fiscal years beginning after December 15, 2024 (the Company’s fiscal quarter ending October 31, 2025), with early adoption permitted. The Company will adopt the standard during the fourth quarter of its fiscal year ending July 31, 2025 and is in the process of evaluating the effect that the adoption of this standard will have on its Consolidated Condensed Financial Statements. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which includes amendments that further enhance the transparency and decision usefulness of income tax disclosures, primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. This update is effective for annual periods beginning after December 15, 2024 (the Company’s fiscal year ending July 31, 2026), though early adoption is permitted. The Company is in the process of evaluating the effect that the adoption of this standard will have on its Consolidated Condensed Financial Statements, including determining the timing of adoption.
