Description of Business	Mar. 31, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business Warner Music Group Corp. (the “Company”) was formed on November 21, 2003. The Company is the direct parent of WMG Holdings Corp. (“Holdings”), which is the direct parent of WMG Acquisition Corp. (“Acquisition Corp.”). Acquisition Corp. is one of the world’s major music entertainment companies. We classify our business interests into two fundamental operations: Recorded Music and Music Publishing. Recorded Music Operations Our Recorded Music business primarily consists of the discovery and development of recording artists and the related marketing, promotion, distribution, sale and licensing of music created by such recording artists. We play an integral role in virtually all aspects of the recorded music value chain from discovering and developing talent to producing, distributing and selling music to marketing and promoting recording artists and their music. Music Publishing Operations While Recorded Music is focused on marketing, promoting, distributing and licensing a particular recording of a musical composition, Music Publishing is an intellectual property business focused on generating revenue from uses of the musical composition itself. In return for promoting, placing, marketing and administering the creative output of a songwriter, or engaging in those activities for other rightsholders, our Music Publishing business shares the revenues generated from use of the musical compositions with the songwriter or other rightsholders.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Interim Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2023. The consolidated balance sheet at September 30, 2022 has been derived from the audited consolidated financial statements at that date but does not include all the information and notes required by U.S. GAAP for complete financial statements. For further information, refer to the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022 (File No. 001-32502). Change in Fiscal Year End On September 29, 2022, the Board of Directors approved a change, effective for the 2023 fiscal year, to the Company’s fiscal year from a modified 52-53-week calendar, in which reporting periods ended on the last Friday of the calendar quarter, to a reporting calendar in which the reporting periods end on the last day of the calendar quarter. Effective for the 2023 fiscal year, the Company’s fiscal year will begin on October 1 and end on September 30 of each year. Prior to the start of the 2023 fiscal year, the Company maintained a 52-53 week fiscal year ending on the last Friday in each reporting period. The fiscal year ended September 30, 2022 included 53 weeks, with the additional week falling in the fiscal quarter ended December 31, 2021. Accordingly, the results of operations for the six months ended March 31, 2022 reflect 27 weeks, or 189 days, compared to 182 days for the six months ended March 31, 2023. For the six months ended March 31, 2022, the revenue benefit of the additional week was approximately $73 million, primarily reflected in Recorded Music streaming revenue. Basis of Consolidation The accompanying financial statements present the consolidated accounts of all entities in which the Company has a controlling voting interest and/or variable interest required to be consolidated in accordance with U.S. GAAP. All intercompany balances and transactions have been eliminated. Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, Consolidation (“ASC 810”) requires the Company first evaluate its investments to determine if any investments qualify as a variable interest entity (“VIE”). A VIE is consolidated if the Company is deemed to be the primary beneficiary of the VIE, which is the party involved with the VIE that has both (i) the power to control the most significant activities of the VIE and (ii) either the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. If an entity is not deemed to be a VIE, the Company consolidates the entity if the Company has a controlling voting interest. The Company has performed a review of all subsequent events through the date the financial statements were issued and has determined that no additional disclosures are necessary. Income Taxes The Company uses the estimated annual effective tax rate method in computing its interim tax provision. Certain items, including those deemed to be unusual and infrequent are excluded from the estimated annual effective tax rate. In such cases, the actual tax expense or benefit is reported in the same period as the related item. Certain tax effects are also not reflected in the estimated annual effective tax rate, primarily certain changes in the realizability of deferred tax assets and uncertain tax positions, and are recorded in the period in which the change occurs. Global Intangible Low-Taxed Income (GILTI) imposes U.S. taxes on the excess of a deemed return on tangible assets of certain foreign subsidiaries. The Company made an election to recognize GILTI tax in the specific period in which it occurs. New Accounting Pronouncements Recently Adopted Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). The amendment provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued because of reference rate reform, if certain criteria are met. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope, which clarified that certain optional expedients and exceptions in Topic 848 apply to derivative instruments that are affected by the discounting transition due to reference rate reform. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date, which extended the period in which Topic 848 may be applied until December 31, 2024. These ASUs were effective upon issuance and may be applied prospectively to contract modifications and hedging relationships entered into or evaluated through December 31, 2024. The discontinuation of LIBOR will impact the Senior Term Loan Facility and a pay-fixed receive-variable interest rate swap which will be outstanding as of the effective date of the discontinuation. The Revolving Credit Facility was amended during the three months ended March 31, 2023 as further described in Note 8. The Company is in the process of evaluating the effect that the adoption of these standards will have on its consolidated financial statements, but does not expect it will have a material effect. Accounting Pronouncements Not Yet Adopted In March 2023, the FASB issued ASU 2023-01, Leases (Topic 842): Common Control Arrangements (“ASU 2023-01”). The amendment clarifies the accounting for leasehold improvements for leases between entities under common control. Specifically, the ASU requires that leasehold improvements associated with common control leases be both: (1) amortized by the lessee over the useful life of the leasehold improvement to the common control group, regardless of the lease term, and (2) accounted for as an adjustment to equity when leasehold improvements are transferred between entities under common control when the lessee no longer controls the leasehold improvements. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023. The Company is in the process of evaluating the effect that the adoption of these standards will have on its consolidated financial statements.

Earnings per Share

Earnings Per Share [Abstract]

Earnings per Share

Earnings per ShareThe Company utilizes the two-class method to report earnings per share. Basic earnings per share is computed by dividing net income available to each class of stock by the weighted average number of outstanding common shares for each class of stock. Diluted earnings per share is computed by dividing net income available to each class of stock by the weighted average number of outstanding common shares, plus dilutive potential common shares, which is calculated using the treasury-stock method. The potentially dilutive common shares did not have a dilutive effect on the Company’s EPS calculation for the three and six months ended March 31, 2023 and 2022, respectively.

The following table sets forth the calculation of basic and diluted net income per common share under the two-class method for the three and six months ended March 31, 2023 and 2022 (in millions, except share amounts, which are reflected in thousands, and per share data):

______________________________________

(a)Reflects $300 million of commitments under the Revolving Credit Facility, less letters of credit outstanding of approximately $4 million at both March 31, 2023 and September 30, 2022. There were no loans outstanding under the Revolving Credit Facility at March 31, 2023 or September 30, 2022.

The Company is the direct parent of Holdings, which is the direct parent of Acquisition Corp. As of March 31, 2023 Acquisition Corp. had issued and outstanding the 2.750% Senior Secured Notes due 2028, the 3.750% Senior Secured Notes due 2029, the 3.875% Senior Secured Notes due 2030, the 2.250% Senior Secured Notes due 2031 and the 3.000% Senior Secured Notes due 2031 (together, the “Acquisition Corp. Notes”).

All of the Acquisition Corp. Notes are guaranteed by all of Acquisition Corp.’s domestic wholly-owned subsidiaries. The guarantee of the Acquisition Corp. Notes by Acquisition Corp.’s domestic wholly-owned subsidiaries is full, unconditional and joint and several. The secured notes are guaranteed on a senior secured basis.

The Company and Holdings are holding companies that conduct substantially all of their business operations through Acquisition Corp. Accordingly, while Acquisition Corp. and its subsidiaries are not currently restricted from distributing funds to the Company and Holdings under the indentures for the Acquisition Corp. Notes or the credit agreements for the Acquisition Corp. Senior Credit Facilities, including the Revolving Credit Facility and the Senior Term Loan Facility, should Acquisition Corp.’s Total Indebtedness to EBITDA Ratio increase above 3.50:1.00 and the term loans not achieve an investment grade rating, the covenants under the Revolving Credit Facility, which are currently suspended, will be reinstated and the ability of the Company and Holdings to obtain funds from their subsidiaries will be restricted by the Revolving Credit Facility. The Company was in compliance with its covenants under its outstanding notes, the Revolving Credit Facility and the Senior Term Loan Facility as of March 31, 2023.

Fiscal 2023 Transactions

Senior Term Loan Facility Amendment

On November 1, 2022, Acquisition Corp. entered into a Seventh Incremental Commitment Amendment (the “Seventh Incremental Commitment Amendment”), with Credit Suisse AG, New York Branch, as Tranche H term lender, and Credit Suisse AG, as administrative agent, and acknowledged by the guarantors party thereto and WMG Holdings Corp., to the Senior Term Loan Credit Agreement, pursuant to which Acquisition Corp. borrowed additional term loans in the amount of $150 million for an aggregate principal amount outstanding under the Senior Term Loan Credit Agreement of $1,295 million. The Seventh Incremental Commitment Amendment was entered into to fund certain deferred payment obligations owing in respect of certain prior acquisitions, to pay fees and expenses relating thereto and for general corporate purposes.

Term Loan Mortgage Agreement

On January 27, 2023, Acquisition Corp., along with Warner Records Inc. and Warner Music Inc., entered into an agreement with Truist Bank, which provides for a term loan of $19 million (“Term Loan Mortgage”) secured by the Company’s real estate properties in Nashville, Tennessee. Interest on the Term Loan Mortgage will accrue at a rate of 30-day SOFR plus the applicable margin of 1.40% subject to a zero floor. Equal principal installments and interest are due monthly.

Revolving Credit Agreement Amendment

On March 23, 2023, Acquisition Corp. entered into an amendment (the “Fourth Revolving Credit Agreement Amendment”) to the Revolving Credit Agreement among Acquisition Corp., the several banks and other financial institutions party thereto and Credit Suisse AG, as administrative agent, governing Acquisition Corp.’s revolving credit facility with Credit Suisse AG, as administrative agent, and the other financial institutions and lenders from time to time party thereto. The Fourth Revolving Credit Agreement Amendment provides for the replacement of LIBOR-based rates with a SOFR-based rate and other rates for alternate currencies, such as EURIBOR and SONIA. We utilized the expedients set forth in ASC Topic 848, including those relating to derivative instruments used in hedging relationships. This transition does not result in a financial impact to our consolidated financial statements.

Interest Rates

The loans under the Revolving Credit Facility bear interest at Acquisition Corp.’s election at a rate equal to (i) the secured overnight financing rate as administered by the Federal Reserve Bank of New York for the applicable interest period (“Revolving Term SOFR”), and other rates for alternate currencies, such as EURIBOR and SONIA, as provided in the Revolving Credit Agreement, subject to a zero floor, plus 1.75% per annum in the case of Initial Revolving Loans (as defined in the Revolving Credit Agreement), or 1.875% per annum in the case of 2020 Revolving Loans (as defined in the Revolving Credit Agreement), or (ii) the base rate, which is the highest of (x) the corporate base rate established by the administrative agent from time to time, (y) 0.50% in excess of the overnight federal funds rate and (z) the one-month Revolving Term SOFR plus 1.0% per annum, plus, in each case, 0.75% per annum in the case of Initial Revolving Loans, or 0.875% per annum in the case of 2020 Revolving Loans; provided that, in respect of 2020 Revolving Loans, the applicable margin with respect to such loans is subject to adjustment as set forth in the pricing grid in the Revolving Credit Agreement. Based on the Senior Secured Indebtedness to EBITDA Ratio of 3.03x at March 31, 2023, the

applicable margin for SOFR loans and RFR loans would be 1.625% instead of 1.875% and the applicable margin for ABR loans would be 0.625% instead of 0.875% in the case of 2020 Revolving Loans. If there is a payment default at any time, then the interest rate applicable to overdue principal will be the rate otherwise applicable to such loan plus 2.0% per annum. Default interest will also be payable on other overdue amounts at a rate of 2.0% per annum above the amount that would apply to an alternative base rate loan.

The Tranche G loans under the Senior Term Loan Facility bear interest at Acquisition Corp.’s election at a rate equal to (i) the rate for deposits in U.S. dollars in the London interbank market (adjusted for maximum reserves) for the applicable interest period (“Term Loan LIBOR”) subject to a zero floor, plus 2.125% per annum or (ii) the base rate, which is the highest of (x) the corporate base rate established by the administrative agent as its prime rate in effect at its principal office in New York City from time to time, (y) 0.50% in excess of the overnight federal funds rate and (z) one-month Term Loan LIBOR, plus 1.00% per annum, subject to a 1.00% floor, plus, in each case, 1.125% per annum. If there is a payment default at any time, then the interest rate applicable to overdue principal and interest will be the rate otherwise applicable to such loan plus 2.0% per annum. Default interest will also be payable on other overdue amounts at a rate of 2.0% per annum above the amount that would apply to an alternative base rate loan.

The Tranche H loans under the Senior Term Loan Facility bear interest at Acquisition Corp.’s election at a rate equal to (i) the forward-looking term rate based on the secured overnight financing rate as administered by the Federal Reserve Bank of New York for the applicable interest period (“Term SOFR”) subject to a 0.50% floor, plus 3.00% per annum or (ii) the base rate, which is the highest of (x) the corporate base rate established by the administrative agent as its prime rate in effect at its principal office in New York City from time to time, (y) 0.50% in excess of the overnight federal funds rate and (z) one-month Term SOFR, plus 1.00% per annum, subject to a 1.50% floor, plus, in each case, 2.00% per annum. If there is a payment default at any time, then the interest rate applicable to overdue principal and interest will be the rate otherwise applicable to such loan plus 2.0% per annum. Default interest will also be payable on other overdue amounts at a rate of 2.0% per annum above the amount that would apply to an alternative base rate loan.

The Term Loan Mortgage bears interest at a rate of 30-day SOFR plus the applicable margin of 1.40%, subject to a zero floor.

The Company has entered into, and in the future may enter into, interest rate swaps to manage interest rate risk. Please refer to Note 13 to our condensed consolidated financial statements for further discussion.

Restructuring and Related Activities [Abstract]

Restructuring

In March 2023, the Company announced a restructuring plan (the “Restructuring Plan”) intended to drive the evolution of the Company and position the Company for long-term growth, primarily through headcount reductions. Under the Restructuring Plan, the Company expects to reduce headcount by approximately 270 people, or approximately 4% of the Company’s overall headcount. The Company expects to incur total non-recurring restructuring charges of approximately $41 million for severance costs, all of which is expected to be paid in cash. The Restructuring Plan is expected to be substantially completed by the end of the fiscal quarter ended June 30, 2023.

For the three and six months ended March 31, 2023, total restructuring costs were $41 million consisting of severance costs. All restructuring expenses were recorded in the Recorded Music segment during the three months ended March 31, 2023.

The following table sets forth the activity in the restructuring accrual included within accrued liabilities in the accompanying condensed consolidated balance sheets:


	Severance Costs

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and ContingenciesFrom time to time the Company is involved in claims and legal proceedings that arise in the ordinary course of business. The Company is currently subject to several such claims and legal proceedings. Based on currently available information, the Company does not believe that resolution of pending matters will have a material adverse effect on its financial condition, cash flows or results of operations. However, litigation is subject to inherent uncertainties, and there can be no assurances that the Company’s defenses will be successful or that any such lawsuit or claim would not have a material adverse impact on the Company’s business, financial condition, cash flows and results of operations in a particular period. Any claims or proceedings against the Company, whether meritorious or not, can have an adverse impact because of defense costs, diversion of management and operational resources, negative publicity and other factors.

Equity	6 Months Ended
Equity	Mar. 31, 2023
Equity [Abstract]
Equity	Equity Stock-Based Compensation The Company’s stock-based compensation plans are described in Note 13, “Stock-Based Compensation Plans,” to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2022. Stock-based compensation consists primarily of restricted stock units (“RSUs”) granted to eligible employees and executives under the Omnibus Incentive Plan. For the three months ended March 31, 2023, the Company recognized a total of $21 million of non-cash stock-based compensation expense, of which $9 million was recorded to additional paid-in capital and $12 million was recorded as a share-based compensation liability. For the six months ended March 31, 2023, the Company recognized a total of $35 million of non-cash stock-based compensation expense, of which $20 million was recorded to additional paid-in capital and $15 million was recorded as a share-based compensation liability. For the six months ended March 31, 2022, the Company recognized a total of $30 million of non-cash stock-based compensation expense, of which $26 million was recorded to additional paid-in capital and $4 million was recorded as a share-based compensation liability. Share-based compensation liabilities, which are a component of accrued liabilities on the condensed consolidated balance sheets, are recorded for awards under the Omnibus Incentive Plan where a total value is known and settlement will occur in a variable number of shares of Class A Common Stock and RSUs. During the three months ended March 31, 2023, $7 million of stock-based compensation liability was reclassified to additional paid-in capital, representing the grant date fair value of RSUs granted which were previously classified as a share-based compensation liability as of December 31, 2022. During the six months ended March 31, 2023, $5 million of stock-based compensation liability was reclassified to additional paid-in capital, representing the grant date fair value of RSUs granted which were previously classified as a share-based compensation liability as of September 30, 2022. During the three and six months ended March 31, 2023, the Company approved the issuance of RSUs under the Omnibus Incentive Plan to eligible employees and executives. For the three and six months ended March 31, 2023, non-cash stock-based compensation associated with these RSUs was $2 million and $10 million, respectively, which was recorded to additional paid-in capital. During the three months ended March 31, 2023, a separation agreement between the Company and our previous Chief Executive Officer was executed. In connection with the separation agreement, the Company recognized $12 million of non-cash stock-based compensation expense associated with RSUs and common stock as there is no remaining service required for vesting. Such expense was recorded as a share-based compensation liability as of March 31, 2023. During the three months ended March 31, 2023, the Company issued market-based performance share units (“PSUs”) to our newly appointed Chief Executive Officer whereby the PSU award payout is determined based on the Company’s total shareholder return compared to a designated peer group. Non-cash stock-based compensation associated with these PSUs recognized for the three and six months ended March 31, 2023 was approximately $1 million, which was recorded to additional paid-in capital. During the three and six months ended March 31, 2023, in connection with the Restructuring Plan, the Company recognized $2 million of non-cash stock-based compensation related to the accelerated vesting of certain RSUs. Refer to Note 9 for further discussion. Common Stock During the six months ended March 31, 2023, in connection with the Senior Management Free Cash Flow Plan (the “Plan”), the Company issued a total of approximately 869,000 shares of Class A Common Stock to settle a portion of a participant’s deferred equity units previously issued under the Plan. During the three and six months ended March 31, 2023, the Company issued approximately 251,000 and 256,000 shares of Class A Common Stock, respectively, under the Omnibus Incentive Plan.

Income Taxes	6 Months Ended
Income Taxes	Mar. 31, 2023
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three and six months ended March 31, 2023, the Company recorded an income tax expense of $21 million and $69 million, respectively. The income tax expense for the six months ended March 31, 2023 is higher than the expected tax expense at the statutory rate of 21% primarily due to U.S. state and local taxes, withholding taxes, foreign income taxed at rates higher than the U.S., and non-deductible executive compensation under IRC Section 162(m), offset by a deduction against foreign derived intangible income (“FDII”). For the three and six months ended March 31, 2022, the Company recorded an income tax expense of $34 million and $109 million, respectively. The income tax expense for the three months ended March 31, 2022 is higher than the expected tax benefit at the statutory tax rate of 21% primarily due to U.S. state and local taxes, withholding taxes, foreign income taxed at rates higher than the U.S., and non-deductible executive compensation under IRC Section 162(m), offset by a deduction against FDII. The Company has determined that it is reasonably possible that the gross unrecognized tax benefits as of March 31, 2023 could decrease by up to approximately $1 million related to various ongoing audits and settlement discussions in various foreign jurisdictions during the next twelve months.

- Definition

Derivative Financial Instruments

6 Months Ended

Mar. 31, 2023

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

The Company uses derivative financial instruments, primarily foreign currency forward exchange contracts and interest rate swaps, for the purposes of managing foreign currency exchange rate risk and interest rate risk on expected future cash flows.

The Company’s hedged interest rate transactions as of March 31, 2023 are expected to be recognized within one year. The fair value of interest rate swaps is based on dealer quotes of market rates (i.e., Level 2 inputs) which is discussed further in Note 19, “Fair Value Measurements,” to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2022. Interest income or expense related to interest rate swaps is recognized in interest income (expense), net in the same period as the related expense is recognized. The ineffective portions of interest rate swaps are recognized in other income (expense) in the period measured.

As of March 31, 2023, the Company had outstanding foreign currency forward exchange contracts for the sale of $304 million and the purchase of $167 million of foreign currencies at fixed rates that will be settled by September 2023.

As of March 31, 2023, the Company had outstanding $500 million in a pay-fixed receive-variable interest rate swap with $8 million of unrealized deferred gains in comprehensive income related to the interest rate swap. As of September 30, 2022, the

Company had outstanding $820 million in pay-fixed receive-variable interest rate swaps with $13 million of unrealized deferred gains in comprehensive income related to the interest rate swaps.

The Company recorded realized pre-tax losses of $2 million and unrealized pre-tax losses of $4 million related to its foreign currency forward exchange contracts in the condensed consolidated statement of operations as other expense for the six months ended March 31, 2023.

Segment Reporting [Abstract]

Segment Information

Based on the nature of its products and services, the Company classifies its business interests into two fundamental operations: Recorded Music and Music Publishing, which also represent the reportable segments of the Company. Information as to each of these operations is set forth below. The Company evaluates performance based on several factors, of which the primary financial measure is operating income (loss) before non-cash depreciation of tangible assets and non-cash amortization of intangible assets (“OIBDA”). The Company has supplemented its analysis of OIBDA results by segment with an analysis of operating income (loss) by segment.

The accounting policies of the Company’s business segments are the same as those described in Note 2, “Summary of Significant Accounting Policies,” to the consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2022. The Company accounts for intersegment sales at fair value as if the sales were to third parties. While intercompany transactions are treated like third-party transactions to determine segment performance, the revenues (and corresponding expenses recognized by the segment that is counterparty to the transaction) are eliminated in consolidation, and therefore, do not themselves impact consolidated results.

Additional Financial Information	6 Months Ended
Additional Financial Information	Mar. 31, 2023
Additional Financial Information [Abstract]
Additional Financial Information	Additional Financial Information Cash Interest and Taxes The Company made interest payments of approximately $50 million and $44 million during the three months ended March 31, 2023 and 2022, respectively, and approximately $75 million and $57 million during the six months ended March 31, 2023 and 2022, respectively. The Company paid approximately $72 million and $37 million of income and withholding taxes, net of refunds, for the three months ended March 31, 2023 and 2022, respectively, and approximately $117 million and $66 million of income and withholding taxes, net of refunds, for the six months ended March 31, 2023 and 2022, respectively. Gain on Divestiture During the six months ended March 31, 2023, the Company sold its interest in certain sound recording rights and recorded a pre-tax gain of $41 million which was recorded as a net gain on divestiture in the accompanying condensed consolidated statement of operations. 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 February 10, 2023, the Company’s board of directors declared a cash dividend of $0.16 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 to stockholders on March 1, 2023. The Company paid an aggregate of approximately $83 million and $167 million, or $0.16 and $0.32 per share, in cash dividends to stockholders and participating security holders for the three and six months ended March 31, 2023, respectively. Noncash Investment Activity Noncash investing activities was approximately $125 million related to the acquisition of music publishing rights and music catalogs, net during the six months ended March 31, 2022.

Fair Value Measurements

The following tables show the fair value of the Company’s financial instruments that are required to be measured at fair value as of March 31, 2023 and September 30, 2022.

Other Noncurrent Liabilities:

______________________________________

(a)The fair value of foreign currency forward exchange contracts is based on dealer quotes of market forward rates and reflects the amount that the Company would receive or pay at their maturity dates for contracts involving the same currencies and maturity dates.

(b)This represents contingent consideration related to acquisitions. This is based on a probability weighted performance approach and it is adjusted to fair value on a recurring basis and any adjustments are typically included as a component of operating income in the condensed consolidated statements of operations. This amount was mainly calculated using unobservable inputs such as future earnings performance of the acquiree and the expected timing of payments.

(c)These represent equity investments with a readily determinable fair value. The Company has measured its investments to fair value in accordance with ASC 321, Investments—Equity Securities, based on quoted prices in active markets.

(d)The fair value of the interest rate swaps is based on dealer quotes of market forward rates and reflects the amount that the Company would receive or pay as of March 31, 2023 for contracts involving the same attributes and maturity dates.

The following table reconciles the beginning and ending balances of net liabilities classified as Level 3:

Reductions	—
Payments	—
Balance at March 31, 2023	$	(1)

The majority of the Company’s non-financial instruments, which include goodwill, intangible assets, inventories and property, plant and equipment, are not required to be re-measured to fair value on a recurring basis. These assets are evaluated for impairment if certain triggering events occur. If such evaluation indicates that impairment exists, the asset is written down to its fair value. In addition, an impairment analysis is performed at least annually for goodwill and indefinite-lived intangible assets.

Equity Investments Without Readily Determinable Fair Value

The Company evaluates its equity investments without readily determinable fair values for impairment if factors indicate that a significant decrease in value has occurred. The Company has elected to use the measurement alternative to fair value that will allow these investments to be recorded at cost, less impairment, and adjusted for subsequent observable price changes. The Company did not record any impairment charges on these investments during the three and six months ended March 31, 2023 and 2022. In addition, there were no observable price changes events that were completed during the three and six months ended March 31, 2023 and 2022.

Fair Value of Debt

Based on the level of interest rates prevailing at March 31, 2023, the fair value of the Company’s debt was $3.628 billion. Based on the level of interest rates prevailing at September 30, 2022, the fair value of the Company’s debt was $3.181 billion. The fair value of the Company’s debt instruments is determined using quoted market prices from less active markets or by using quoted market prices for instruments with identical terms and maturities; both approaches are considered a Level 2 measurement.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities.

Summary of Significant Accounting Policies (Policies)	6 Months Ended
Summary of Significant Accounting Policies (Policies)	Mar. 31, 2023
Accounting Policies [Abstract]
Interim Financial Statements	Interim Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and notes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and six months ended March 31, 2023 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2023. The consolidated balance sheet at September 30, 2022 has been derived from the audited consolidated financial statements at that date but does not include all the information and notes required by U.S. GAAP for complete financial statements. For further information, refer to the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022 (File No. 001-32502).
Change in Fiscal Year End	Change in Fiscal Year End On September 29, 2022, the Board of Directors approved a change, effective for the 2023 fiscal year, to the Company’s fiscal year from a modified 52-53-week calendar, in which reporting periods ended on the last Friday of the calendar quarter, to a reporting calendar in which the reporting periods end on the last day of the calendar quarter. Effective for the 2023 fiscal year, the Company’s fiscal year will begin on October 1 and end on September 30 of each year. Prior to the start of the 2023 fiscal year, the Company maintained a 52-53 week fiscal year ending on the last Friday in each reporting period. The fiscal year ended September 30, 2022 included 53 weeks, with the additional week falling in the fiscal quarter ended December 31, 2021. Accordingly, the results of operations for the six months ended March 31, 2022 reflect 27 weeks, or 189 days, compared to 182 days for the six months ended March 31, 2023. For the six months ended March 31, 2022, the revenue benefit of the additional week was approximately $73 million, primarily reflected in Recorded Music streaming revenue.
Basis of Consolidation	Basis of Consolidation The accompanying financial statements present the consolidated accounts of all entities in which the Company has a controlling voting interest and/or variable interest required to be consolidated in accordance with U.S. GAAP. All intercompany balances and transactions have been eliminated. Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, Consolidation (“ASC 810”) requires the Company first evaluate its investments to determine if any investments qualify as a variable interest entity (“VIE”). A VIE is consolidated if the Company is deemed to be the primary beneficiary of the VIE, which is the party involved with the VIE that has both (i) the power to control the most significant activities of the VIE and (ii) either the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. If an entity is not deemed to be a VIE, the Company consolidates the entity if the Company has a controlling voting interest.
Income Taxes	Income Taxes The Company uses the estimated annual effective tax rate method in computing its interim tax provision. Certain items, including those deemed to be unusual and infrequent are excluded from the estimated annual effective tax rate. In such cases, the actual tax expense or benefit is reported in the same period as the related item. Certain tax effects are also not reflected in the estimated annual effective tax rate, primarily certain changes in the realizability of deferred tax assets and uncertain tax positions, and are recorded in the period in which the change occurs. Global Intangible Low-Taxed Income (GILTI) imposes U.S. taxes on the excess of a deemed return on tangible assets of certain foreign subsidiaries. The Company made an election to recognize GILTI tax in the specific period in which it occurs.
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted Accounting Pronouncements In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). The amendment provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued because of reference rate reform, if certain criteria are met. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope, which clarified that certain optional expedients and exceptions in Topic 848 apply to derivative instruments that are affected by the discounting transition due to reference rate reform. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date, which extended the period in which Topic 848 may be applied until December 31, 2024. These ASUs were effective upon issuance and may be applied prospectively to contract modifications and hedging relationships entered into or evaluated through December 31, 2024. The discontinuation of LIBOR will impact the Senior Term Loan Facility and a pay-fixed receive-variable interest rate swap which will be outstanding as of the effective date of the discontinuation. The Revolving Credit Facility was amended during the three months ended March 31, 2023 as further described in Note 8. The Company is in the process of evaluating the effect that the adoption of these standards will have on its consolidated financial statements, but does not expect it will have a material effect. Accounting Pronouncements Not Yet Adopted In March 2023, the FASB issued ASU 2023-01, Leases (Topic 842): Common Control Arrangements (“ASU 2023-01”). The amendment clarifies the accounting for leasehold improvements for leases between entities under common control. Specifically, the ASU requires that leasehold improvements associated with common control leases be both: (1) amortized by the lessee over the useful life of the leasehold improvement to the common control group, regardless of the lease term, and (2) accounted for as an adjustment to equity when leasehold improvements are transferred between entities under common control when the lessee no longer controls the leasehold improvements. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023. The Company is in the process of evaluating the effect that the adoption of these standards will have on its consolidated financial statements.
