Accounting Policies [Abstract]
Accounting Policies	Accounting Policies Principles of Consolidation The consolidated financial statements of the Company include the accounts of MSG Knickerbockers Corp. and its subsidiaries. All significant intracompany transactions and accounts within the Financial Statements have been eliminated. Use of Estimates The preparation of the Financial Statements in conformity with GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of accounts receivable, other current assets, goodwill, intangible assets, other long-lived assets, fair value of investments, deferred tax valuation allowance, tax accruals and other liabilities. In addition, estimates are used in revenue recognition, revenue sharing expense (net of escrow), luxury tax expense, income tax expense (benefit), performance and share-based compensation, depreciation and amortization, litigation matters and other matters. Management believes its use of estimates in the Financial Statements to be reasonable. Management evaluates its estimates on an ongoing basis using historical experience and other factors, including the general economic environment and actions it may take in the future. The Company adjusts such estimates when facts and circumstances dictate. However, these estimates may involve significant uncertainties and judgments and cannot be determined with precision. In addition, these estimates are based on management’s best judgment at a point in time and, as such, these estimates may ultimately differ from actual results. Changes in estimates resulting from weakness in the economic environment or other factors beyond the Company’s control could be material and would be reflected in the Company’s financial statements in future periods. Recent Accounting Pronouncements Recently Issued Accounting Pronouncements Not Yet Adopted In November 2024, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The ASU requires the disclosure of additional information about specific expense categories in the notes to the financial statements. The ASU is effective for the Company’s Annual Report on Form 10-K for the fiscal year ending June 30, 2028 and subsequent interim periods, with early adoption permitted. The Company is currently evaluating the impact this standard will have on its disclosures. In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) - Targeted Improvements to the Accounting for Internal-Use Software. The ASU modernizes and clarifies the threshold for when an entity is required to start capitalizing software costs and is based on when (i) management has authorized and committed to funding the software project and (ii) it is probable that the project will be completed and the software will be used to perform the function intended. The ASU is effective for the Company in the first quarter of the fiscal year ending June 30, 2029. The Company is currently evaluating the impact this standard will have on its consolidated financial statements.
