Organization, Consolidation and Presentation of Financial Statements [Abstract]
Additional Financial Information	Additional Financial Information Cash Interest and Taxes The Company made interest payments of approximately $137 million, $128 million and $138 million during the fiscal years ended September 30, 2021, September 30, 2020 and September 30, 2019, respectively. The Company paid approximately $124 million, $81 million and $63 million of income and withholding taxes, net of refunds, for the fiscal years ended September 30, 2021, September 30, 2020 and September 30, 2019, respectively. Dividends The Company’s ability to pay dividends may be restricted by covenants in the credit agreement for the Revolving Credit Facility which are currently suspended but which will be reinstated if Acquisition Corp.’s Total Indebtedness to EBITDA Ratio increases above 3.50:1.00 and the term loans do not achieve an investment grade rating. The Company intends to pay quarterly cash dividends to holders of its Class A Common Stock and Class B Common Stock. The declaration of each dividend will continue to be at the discretion of the Company’s board of directors and will depend on the Company’s financial condition, earnings, liquidity and capital requirements, level of indebtedness, contractual restrictions with respect to payment of dividends, restrictions imposed by Delaware law, general business conditions and any other factors that the Company’s board of directors deems relevant in making such a determination. Therefore, there can be no assurance that the Company will pay any dividends to holders of the Company’s common stock, or as to the amount of any such dividends. On August 13, 2021, the Company’s board of directors declared a cash dividend of $0.15 per share on the Company’s Class A Common Stock and Class B Common Stock, as well as related payments under certain stock-based compensation plans, which was paid on September 1, 2021. The Company paid cash dividends to stockholders and participating security holders of $265 million, $344 million and $94 million for the fiscal years ended September 30, 2021, 2020 and 2019, respectively. On November 9, 2021, the Company’s board of directors declared a cash dividend of $0.15 per share on the Company’s Class A Common Stock and Class B Common Stock, as well as related payments under certain stock-based compensation plans, payable on December 1, 2021 to stockholders of record as of the close of business on November 23, 2021. COVID-19 Pandemic On March 11, 2020, the COVID-19 outbreak was declared a global pandemic by the World Health Organization. Government-imposed mandates limiting public assembly and restrictions on non-essential businesses have adversely impacted the Company’s operations for the fiscal year ended September 30, 2021, including touring and live events. As global vaccination efforts are underway and businesses are beginning to reopen, revenues improved due to the partial recovery of certain COVID-19 impacted revenue streams despite a rise in COVID-19 cases associated with the Delta variant. The continued impact of COVID-19, including increases in infection rates, new variants, renewed governmental action to slow the spread of COVID-19 and to what extent it will impact the Company’s music and related services cannot be predicted. The Company is not presently aware of any events or circumstances arising from the global pandemic that would require us to update any estimates, judgments or materially revise the carrying value of our assets or liabilities. The Company’s estimates may change, however, as new events occur and additional information is obtained, and any such changes will be recognized in the consolidated financial statements. Actual results could differ from estimates, and any such differences may be material to our consolidated financial statements.
