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. Acquisition of Warner Music Group by Access Industries Pursuant to the Agreement and Plan of Merger, dated as of May 6, 2011 (the “Merger Agreement”), by and among the Company, AI Entertainment Holdings LLC (formerly Airplanes Music LLC), a Delaware limited liability company (“Parent”) and an affiliate of Access Industries, Inc. (“Access”), and Airplanes Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), on July 20, 2011 (the “Merger Closing Date”), Merger Sub merged with and into the Company with the Company surviving as a wholly owned subsidiary of Parent (the “Merger”). In connection with the Merger, the Company delisted its common stock from the New York Stock Exchange (the “NYSE”). The Company continues to voluntarily file with the U.S. Securities and Exchange Commission (the “SEC”) current and periodic reports that would be required to be filed with the SEC pursuant to Section 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as provided for in certain covenants contained in the instruments covering its outstanding indebtedness. All of the Company’s common stock is owned by affiliates of Access. 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. In the United States, our Recorded Music business is conducted principally through our major record labels—Atlantic Records and Warner Records. In October 2018, we launched Elektra Music Group in the United States as a standalone label group, which comprises the Elektra, Fueled by Ramen and Roadrunner labels. Our Recorded Music business also includes Rhino Entertainment, a division that specializes in marketing our recorded music catalog through compilations, reissuances of previously released music and video titles and releasing previously unreleased material from our vault. We also conduct our Recorded Music business through a collection of additional record labels including Asylum, Big Beat, Canvasback, East West, Erato, FFRR, Nonesuch, Parlophone, Reprise, Sire, Spinnin’, Warner Classics and Warner Music Nashville. Outside the United States, our Recorded Music business is conducted in more than 70 countries through various subsidiaries, affiliates and non-affiliated licensees. Internationally, we engage in the same activities as in the United States: discovering and signing artists and distributing, selling, marketing and promoting their music. In most cases, we also market, promote, distribute and sell the music of those recording artists for whom our domestic record labels have international rights. In certain smaller markets, we license the right to distribute and sell our music to non-affiliated third-party record labels. Our Recorded Music business’ distribution operations include Warner-Elektra-Atlantic Corporation (“WEA Corp.”), which markets, distributes and sells music and video products to retailers and wholesale distributors; Alternative Distribution Alliance (“ADA”), which markets, distributes and sells the products of independent labels to retail and wholesale distributors; and various distribution centers and ventures operated internationally. In addition to our music being sold in physical retail outlets, our music is also sold in physical form to online physical retailers, such as Amazon.com, barnesandnoble.com and bestbuy.com, and distributed in digital form to an expanded universe of digital partners, including streaming services such as those of Amazon, Apple, Deezer, SoundCloud, Spotify, Tencent Music Entertainment Group and YouTube, radio services such as iHeart Radio and SiriusXM and download services such as Apple’s iTunes and Google Play. We have integrated the marketing of digital content into all aspects of our business, including artist and repertoire (“A&R”) and distribution. Our business development executives work closely with A&R departments to ensure that while music is being produced, digital assets are also created with all distribution channels in mind, including streaming services, social networking sites, online portals and music-centered destinations. We also work side-by-side with our online and mobile partners to test new concepts. We believe existing and new digital businesses will be a significant source of growth and will provide new opportunities to successfully monetize our assets and create new revenue streams. The proportion of digital revenues attributable to each distribution channel varies by region and proportions may change as the introduction of new technologies continues. As one of the world’s largest music entertainment companies, we believe we are well positioned to take advantage of growth in digital distribution and emerging technologies to maximize the value of our assets. We have diversified our revenues beyond our traditional businesses by entering into expanded-rights deals with recording artists in order to partner with such artists in other aspects of their careers. Under these agreements, we provide services to and participate in recording artists’ activities outside the traditional recorded music business such as touring, merchandising and sponsorships. We have built and acquired artist services capabilities and platforms for marketing and distributing this broader set of music-related rights and participating more widely in the monetization of the artist brands we help create. We believe that entering into expanded-rights deals and enhancing our artist services capabilities in areas such as merchandising, VIP ticketing, fan clubs, concert promotion and management has permitted us to diversify revenue streams and capitalize on other revenue opportunities. This provides for improved long-term relationships with our recording artists and allows us to more effectively connect recording artists and fans. 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 garners a share of the revenues generated from use of the musical compositions. The operations of our Music Publishing business are conducted principally through Warner Chappell Music, our global music publishing company headquartered in Los Angeles with operations in over 70 countries through various subsidiaries, affiliates and non-affiliated licensees. We own or control rights to more than 1.4 million musical compositions, including numerous pop hits, American standards, folk songs and motion picture and theatrical compositions. Assembled over decades, our award-winning catalog includes over 80,000 songwriters and composers and a diverse range of genres including pop, rock, jazz, classical, country, R&B, hip-hop, rap, reggae, Latin, folk, blues, symphonic, soul, Broadway, techno, alternative and gospel. Warner Chappell Music also administers the music and soundtracks of several third-party television and film producers and studios. We have an extensive production music catalog collectively branded as Warner Chappell Production Music.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Interim Financial Statements The accompanying unaudited 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 month period ended December 31, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2020. The consolidated balance sheet at September 30, 2019 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, 2019 (File No. 001-32502). 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 maintains a 52-53 week fiscal year ending on the last Friday in each reporting period. As such, all references to December 31, 2019 and December 31, 2018 relate to the periods ended December 27, 2019 and December 28, 2018, respectively. For convenience purposes, the Company continues to date its financial statements as of December 31. The fiscal year ended September 30, 2019 ended on September 27, 2019. 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. New Accounting Pronouncements Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”), which established a new ASC Topic 842 (“ASC 842”) that introduces a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. In July 2018, the FASB issued ASU 2018-11, Leases – Targeted Improvements (“ASU 2018-11”), which allows for retrospective application with the recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Under this option, entities do not need to apply ASC 842 (along with its disclosure requirements) to the comparative prior periods presented. The Company adopted ASU 2016-02 on October 1, 2019, using the modified retrospective transition method provided by ASU 2018-11. The adoption of ASU 2016-02 resulted in the recognition of operating lease liabilities of $366 million and ROU assets of $297 million, which is net of the historical deferred rent liability balance of $69 million, primarily related to real estate leases. The Company also recorded a decrease to opening accumulated deficit of $7 million, net of taxes, related to previously deferred gains related to sale-leaseback transactions. Upon transition, the Company adopted the “package of three” practical expedient provided by ASC 842 and therefore has not (1) reassessed whether any expired or existing contracts are or contain a lease, (2) reassessed the lease classification for expired or existing leases and (3) reassessed initial direct costs for any existing leases. Rather, the Company will retain the conclusions reached for these items under ASC 840. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”). This ASU improves certain aspects of the hedge accounting model including making more risk management strategies eligible for hedge accounting and simplifying the assessment of hedge effectiveness. ASU 2017-12 is effective for all annual periods beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted and requires a prospective adoption with a cumulative-effect adjustment to accumulated deficit as of the beginning of the fiscal year of adoption for existing hedging relationships. The Company adopted ASU 2017-12 in the first quarter of fiscal 2020 and this adoption did not have a significant impact on the Company’s financial statements. Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 requires that expected credit losses relating to financial assets measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. ASU 2016-13 limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. ASU 2016-13 will be effective for annual periods beginning after December 15, 2019, and interim periods within those fiscal years. Earlier adoption is permitted. The Company is evaluating the impact of the adoption of this standard on its consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”). This ASU eliminates certain exceptions to the general principles in ASC 740, Income Taxes . Specifically, it eliminates the exception to (1) the incremental approach for intraperiod tax allocation when there is a loss from continuing operations, and income or a gain from

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition For our operating segments, Recorded Music and Music Publishing, the Company accounts for a contract when it has legally enforceable rights and obligations and collectability of consideration is probable. The Company identifies the performance obligations and determines the transaction price associated with the contract, which is then allocated to each performance obligation, using management’s best estimate of standalone selling price for arrangements with multiple performance obligations. Revenue is recognized when, or as, control of the promised services or goods is transferred to the Company’s customers, and in an amount that reflects the consideration the Company is contractually due in exchange for those services or goods. An estimate of variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Certain of the Company’s arrangements include licenses of intellectual property with consideration in the form of sales- and usage-based royalties. Royalty revenue is recognized when the subsequent sale or usage occurs using the best estimates available of the amounts that will be received by the Company. Disaggregation of Revenue The Company’s revenue consists of the following categories, which aggregate into the segments – Recorded Music and Music Publishing: For the Three Months Ended 2019 2018 (in millions) Revenue by Type Digital $ 633 $ 563 Physical 184 231 Total Digital and Physical 817 794 Artist services and expanded-rights 188 166 Licensing 79 81 Total Recorded Music 1,084 1,041 Performance 46 53 Digital 73 65 Mechanical 15 15 Synchronization 36 29 Other 3 3 Total Music Publishing 173 165 Intersegment eliminations (1) (3) Total Revenues $ 1,256 $ 1,203 Revenue by Geographical Location U.S. Recorded Music $ 453 $ 431 U.S. Music Publishing 81 73 Total U.S. 534 504 International Recorded Music 631 610 International Music Publishing 92 92 Total International 723 702 Intersegment eliminations (1) (3) Total Revenues $ 1,256 $ 1,203 Recorded Music Recorded Music mainly involves selling, marketing, distribution and licensing of recorded music produced by the Company’s recording artists. Recorded Music revenues are derived from four main sources, which include digital, physical, artist services and expanded-rights and licensing. Digital revenues are generated from the expanded universe of digital partners, including digital streaming services and download services. These licenses typically contain a single performance obligation, which is ongoing access to all intellectual property in an evolving content library, predicated on: (1) the business practice and contractual ability to remove specific content without a requirement to replace the content and without impact to minimum royalty guarantees and (2) the contracts not containing a specific listing of content subject to the license. Digital licensing contracts are generally long-term with consideration in the form of sales- and usage-based royalties that are typically received monthly. Certain contracts contain non-recoupable fixed fees or minimum guarantees, which are recoupable against royalties. Upon contract inception, the Company will assess whether a shortfall or breakage is expected (i.e., where the minimum guarantee will not be recouped through royalties) in order to determine timing of revenue recognition for the fixed fee or minimum guarantee. For fixed fee and minimum guarantee contracts where breakage is expected, the total transaction price (fixed fee or minimum guarantee) is recognized proportionately over the contract term using an appropriate measure of progress which is typically based on the Company’s digital partner’s subscribers or streaming activity as these are measures of access to an evolving catalog, or on a straight-line basis. The Company updates its assessment of the transaction price each reporting period to see if anticipated royalty earnings exceed the minimum guarantee. For contracts where breakage is not expected, royalties are recognized as revenue as sales or usage occurs based upon the licensee’s usage reports and, when these reports are not available, revenue is based on historical data, industry information and other relevant trends. Additionally, for certain licenses where the consideration is fixed and the intellectual property being licensed is static, revenue is recognized at the point in time when control of the licensed content is transferred to the customer. Physical revenues are generated from the sale of physical products such as vinyl, CDs and DVDs. Revenues from the sale of physical Recorded Music products are recognized upon transfer of control to the customer, which typically occurs once the product has been shipped and the ability to direct use and obtain substantially all of the benefit from the asset have been transferred. In accordance with industry practice and as is customary in many territories, certain products, such as CDs and DVDs, are sold to customers with the right to return unsold items. Revenues from such sales are generally recognized upon shipment based on gross sales less a provision for future estimated returns. Artist services and expanded-rights revenues are generated from artist services businesses and participations in expanded-rights associated with artists, including sponsorship, fan clubs, artist websites, merchandising, touring, concert promotion, ticketing and artist and brand management. Artist services and expanded-rights contracts are generally short term. Revenue is recognized as or when services are provided (e.g., at time of an artist’s event) assuming collectability is probable. In some cases, the Company is reliant on the artist to report revenue generating activities. For certain artist services and expanded-rights contracts, collectability is not considered probable until notification is received from the artist’s management. Licensing revenues represent royalties or fees for the right to use sound recordings in combination with visual images such as in films or television programs, television commercials and video games. In certain territories, the Company may also receive royalties when sound recordings are performed publicly through broadcast of music on television, radio and cable and in public spaces such as shops, workplaces, restaurants, bars and clubs. Licensing contracts are generally short term. For fixed-fee contracts, revenue is recognized at the point in time when control of the licensed content is transferred to the customer. Royalty based contracts are recognized as the underlying sales or usage occurs. Music Publishing Music Publishing acts as a copyright owner and/or administrator of the musical compositions and generates revenues related to the exploitation of musical compositions (as opposed to recorded music). Music publishers generally receive royalties from the use of the musical compositions in public performances, digital and physical recordings and in combination with visual images. Music publishing revenues are derived from five main sources: mechanical, performance, synchronization, digital and other. Performance revenues are received when the musical composition is performed publicly through broadcast of music on television, radio and cable, live performance at a concert or other venue (e.g., arena concerts and nightclubs) and performance of musical compositions in staged theatrical productions. Digital revenues are generated with respect to the musical compositions being embodied in recordings licensed to digital streaming services and digital download services and for digital performance. Mechanical revenues are generated with respect to the musical compositions embodied in recordings sold in any physical format or configuration such as vinyl, CDs and DVDs. Synchronization revenues represent the right to use the composition in combination with visual images such as in films or television programs, television commercials and video games as well as from other uses such as in toys or novelty items and merchandise. Other revenues represent earnings for use in printed sheet music and other uses. Digital and synchronization revenue recognition is similar for both Recorded Music and Music Publishing, therefore refer to the discussion within Recorded Music. Included in these revenue streams, excluding synchronization and other, are licenses with performing rights organizations or collecting societies (e.g., ASCAP, BMI, SESAC and GEMA), which are long-term contracts containing a single performance obligation, which is ongoing access to all intellectual property in an evolving content library. The most common form of consideration for these contracts is sales- and usage-based royalties. The collecting societies submit usage reports, typically with payment for royalties due, often on a quarterly or biannual reporting period, in arrears. Royalties are recognized as the sale or usage occurs based upon usage reports and, when these reports are not available, royalties are estimated based on historical data, such as recent royalties reported, company-specific information with respect to changes in repertoire, industry information and other relevant trends. Also included in these revenue streams are smaller, short-term contracts for specified content, which generally involve a fixed fee. For fixed-fee contracts, revenue is recognized at the point in time when control of the license is transferred to the customer. The Company excludes from the measurement of transaction price all taxes assessed by governmental authorities that are both (i) imposed on and concurrent with a specific revenue-producing transaction and (ii) collected from customers. Sales Returns and Uncollectible Accounts In accordance with practice in the recorded music industry and as customary in many territories, certain physical revenue products (such as CDs and DVDs) are sold to customers with the right to return unsold items. Revenues from such sales are recognized when the products are shipped based on gross sales less a provision for future estimated returns. In determining the estimate of physical product sales that will be returned, management analyzes vendor sales of product, historical return trends, current economic conditions, changes in customer demand and commercial acceptance of the Company’s products. Based on this information, management reserves a percentage of each dollar of physical product sales that provide the customer with the right of return and records an asset for the value of the returned goods and liability for the amounts expected to be refunded. Similarly, management evaluates accounts receivables to determine if they will ultimately be collected. In performing this evaluation, significant judgments and estimates are involved, including an analysis of specific risks on a customer-by-customer basis for larger accounts and customers and a receivables aging analysis that determines the percent that has historically been uncollected by aged category. The time between the Company’s issuance of an invoice and payment due date is not significant; customer payments that are not collected in advance of the transfer of promised services or goods are generally due no later than 30 days from invoice date. Based on this information, management provides a reserve for the estimated amounts believed to be uncollectible. Based on management’s analysis of sales returns, refund liabilities of $36 million and $23 million were established at December 31, 2019 and September 30, 2019, respectively. Based on management’s analysis of uncollectible accounts, reserves of $18 million and $17 million were established at December 31, 2019 and September 30, 2019, respectively. Principal versus Agent Revenue Recognition The Company reports revenue on a gross or net basis based on management’s assessment of whether the Company acts as a principal or agent in the transaction. The determination of whether the Company acts as a principal or an agent in a transaction is based on an evaluation of whether the Company controls the good or service before transfer to the customer. When the Company concludes that it controls the good or service before transfer to the customer, the Company is considered a principal in the transaction and records revenue on a gross basis. When the Company concludes that it does not control the good or service before transfer to the customer but arranges for another entity to provide the good or service, the Company acts as an agent and records revenue on a net basis in the amount it earns for its agency service. In the normal course of business, the Company acts as an intermediary with respect to certain payments received from third parties. For example, the Company distributes music content on behalf of third-party record labels. Based on the above guidance, the Company records the distribution of content on behalf of third-party record labels on a gross basis, subject to the terms of the contract, as the Company controls the content before transfer to the customer. Conversely, recorded music compilations distributed by other record companies where the Company has a right to participate in the profits are recorded on a net basis. Deferred Revenue Deferred revenue principally relates to fixed fees and minimum guarantees received in advance of the Company’s performance or usage by the licensee. Reductions in deferred revenue are a result of the Company’s performance under the contract or usage by the licensee. Deferred revenue increased $96 million during the three months ended December 31, 2019 related to cash received from customers for fixed fees and minimum guarantees in advance of performance, including amounts recognized in the period. Revenues of $73 million were recognized during the three months ended December 31, 2019 related to the balance of deferred revenue at September 30, 2019. There were no other significant changes to deferred revenue during the reporting period. Performance Obligations The Company recognized revenue of $27 million and $17 million from performance obligations satisfied in previous periods for the three month periods ended December 31, 2019 and December 31, 2018, respectively. Wholly and partially unsatisfied performance obligations represent future revenues not yet recorded under long term intellectual property licensing contracts. Revenues expected to be recognized in the future related to performance obligations that are unsatisfied at December 31, 2019 are as follows (in millions): Rest of FY20 FY21 FY22 Thereafter Total (in millions) Remaining performance obligations $ 483 $ 661 $ 7 $ — $ 1,151 Total $ 483 $ 661 $ 7 $ — $ 1,151

Leases [Abstract]
Leases	LeasesThe Company’s lease portfolio consists operating real estate leases for its corporate offices and, to a lesser extent, storage and other equipment, Under ASC 842, a contract is or contains a lease when (1) an explicitly or implicitly identified asset has been deployed in the contract and (2) the customer obtains substantially all of the economic benefits from the use of that underlying asset and directs how and for what purpose the asset is used during the term of the contract. The Company determines if an arrangement is or contains a lease at inception of the contract. For all leases (finance and operating), other than those that qualify for the short-term recognition exemption, the Company will recognize on the balance sheet a lease liability for its obligation to make lease payments arising from the lease and a corresponding ROU asset representing its right to use the underlying asset over the period of use based on the present value of lease payments over the lease term as of the lease commencement date. ROU assets are adjusted for initial direct costs, lease payments made and incentives. As the rates implicit in our leases are not readily determinable, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. This rate is based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments. The lease term used to calculate the lease liability will include options to extend or terminate the lease when the option to extend or terminate is at the Company’s discretion and it is reasonably certain that the Company will exercise the option. Fixed payments are recognized as lease expense on a straight-line basis over the lease term. For leases with a term of one year or less (“short-term leases”), the lease payments are recognized in the consolidated statement of operations on a straight-line basis over the lease term. ASC 842 requires that only limited types of variable payments be included in the determination of lease payments, which affects lease classification and measurement. Variable lease costs, if any, are recognized as incurred and such costs are excluded from lease balances recorded on the consolidated balance sheet. The initial measurement of the lease liability and ROU asset are determined based on both the fixed lease payments and any variable lease payments that depend on an index or a rate (such as the Consumer Price Index or a market interest rate). The Company initially measures these variable lease payments using the index or rate at lease commencement (i.e., the spot or gross index or rate applied to the base rental amount). All other variable lease payments are recognized in the period in which the payments are incurred. The Company’s operating ROU assets are included in operating lease right-of-use assets and the Company’s current and non-current operating lease liabilities are included in operating lease liabilities, current and operating lease liabilities, noncurrent, respectively, in the Company’s balance sheet. Operating lease liabilities are amortized using the effective interest method. That is, in each period, the liability will be increased to reflect the interest that is accrued on the related liability by using the appropriate discount rate and decreased by the lease payments made during the period. The subsequent measurement of the ROU asset is linked to the amount recognized as the lease liability. Accordingly, the ROU asset is measured as the lease liability adjusted by (1) accrued or prepaid rents (i.e., the aggregate difference between the cash payment and straight-line lease cost), (2) remaining unamortized initial direct costs and lease incentives, and (3) impairments of the ROU asset. Operating lease costs are included in Selling, general and administrative expenses. For lease agreements that contain both lease and non-lease components, the Company has elected the practical expedient provided by ASC 842 that permits the accounting for these components as a single lease component (rather than separating the lease from the non-lease components and accounting for the components individually). The Company enters into operating leases for buildings, office equipment, production equipment, warehouses, and other types of equipment. Our leases have remaining lease terms of 1 year to 12 years, some of which include options to extend the leases for up to 10 years, and some of which include options to terminate the leases within 1 year. The Company has two operating leases, for the Ford Factory Building, located at 777 S. Santa Fe Avenue in Los Angeles, California, and for 27 Wrights Lane, Kensington, London, which the landlord for both leases is an affiliate of Access. As of December 31, 2019, the aggregate lease liability related to these leases was $142 million. There are no restrictions or covenants, such as those relating to dividends or incurring additional financial obligations, relating to our lease portfolio, and residual value guarantees are not significant. The components of lease expense were as follows: Three Months Ended (in millions) Lease Cost Operating lease cost $ 14 Short-term lease cost — Variable lease cost 3 Sublease income — Total lease cost $ 17 Supplemental cash flow information related to leases was as follows: Three Months Ended (in millions) Cash paid for amounts included in the measurement of operating lease liabilities $ 14 Right-of-use assets obtained in exchange for operating lease obligations 5 Supplemental balance sheet information related to leases was as follows: December 31, (in millions) Operating Leases Operating lease right-of-use assets $ 289 Operating lease liabilities, current $ 38 Operating lease liabilities, noncurrent 321 Total operating lease liabilities $ 359 Weighted Average Remaining Lease Term Operating leases 9 years Weighted Average Discount Rate Operating leases 4.55 % Maturities of lease liabilities were as follows: Years Operating (in millions) 2020 $ 53 2021 52 2022 49 2023 47 2024 47 Thereafter 191 Total lease payments 439 Less imputed interest (80) Total $ 359 As of December 31, 2019, there have been no leases entered into that have not yet commenced.

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.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (“Tax Act”). The Tax Act significantly revised the U.S. federal corporate income tax provisions, including, but not limited to, an income inclusion of global intangible low-taxed income (“GILTI”), a deduction against foreign-derived intangible income (“FDII”) and a new minimum tax, the base erosion anti-abuse tax (“BEAT”). GILTI, FDII and BEAT were effective for the Company’s fiscal year ending September 30, 2019. The Company has elected to recognize the GILTI impact in the specific period in which it occurs. As a result of final regulations regarding the interest expense allocation rules issued by the Internal Revenue Service in December 2019, the Company concluded that it is more likely than not that the entire amount of the Company’s deferred tax assets relating to foreign tax credit carryforwards will be realized. Consequently, the Company released its $33 million valuation allowance at September 30, 2019 relating to such deferred tax assets and recognized a corresponding U.S. tax benefit of $33 million during the quarter ended December 31, 2019. The Company will continue to weigh the evidence including the projections of sufficient future taxable income, foreign source income and the reversal of future taxable temporary differences to assess the future realization of our foreign tax credits. For the three months ended December 31, 2019, the Company recorded an income tax expense of $5 million. The income tax expense for the three months ended December 31, 2019 is lower than the expected tax at the statutory tax rate of 21% primarily due to tax benefit of the valuation allowance release relating to foreign tax credit carryforwards and FDII, offset by non-deductible long term incentive plan, U.S. state and local taxes, foreign income taxed at rates higher than the U.S. statutory tax rate, withholding taxes and foreign losses with no tax benefit. For the three months ended December 31, 2018, the Company recorded an income tax expense of $50 million. The income tax expense for the three months ended December 31, 2018 is higher than the expected tax at the statutory tax rate of 21% primarily due to GILTI, non-deductible long term incentive plan, U.S. state and local taxes, foreign income taxed at rates higher than the U.S. statutory tax rate, withholding taxes, foreign losses with no tax benefit offset by the tax benefit of a reduction in foreign income tax rates. The Company has determined that it is reasonably possible that the gross unrecognized tax benefits as of December 31, 2019 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.

Derivative Financial Instrument

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	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. However, the Company may choose not to hedge certain exposures for a variety of reasons including, but not limited to, accounting considerations and the prohibitive economic cost of hedging particular exposures. There can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in foreign currency exchange or interest rates. The Company enters into foreign currency forward exchange contracts primarily to hedge the risk that unremitted or future royalties and license fees owed to its U.S. companies for the sale or licensing of U.S.-based music and merchandise abroad may be adversely affected by changes in foreign currency exchange rates. The Company focuses on managing the level of exposure to the risk of foreign currency exchange rate fluctuations on its major currencies, which include the Euro, British pound sterling, Japanese yen, Canadian dollar, Swedish krona, Australian dollar, Brazilian real, Korean won and Norwegian krone. The Company also may at times choose to hedge foreign currency risk associated with financing transactions such as third-party debt and other balance sheet items. The Company’s foreign currency forward exchange contracts have not been designated as hedges under the criteria prescribed in ASC 815. The Company records these contracts at fair value on its balance sheet and the related gains and losses are immediately recognized in the consolidated statement of operations where there is an offsetting entry related to the underlying exposure. In prior periods, certain foreign currency forward exchange contracts were designated and qualified as cash flow hedges under the criteria prescribed in ASC 815. The Company recorded these contracts at fair value on its balance sheet and gains or losses on these contracts were deferred in equity (as a component of comprehensive loss). These deferred gains and losses were recognized in income in the period in which the related royalties and license fees being hedged were received and recognized in income. However, to the extent that any of these contracts were not considered to be perfectly effective in offsetting the change in the value of the royalties and license fees being hedged, any changes in fair value relating to the ineffective portion of these contracts were immediately recognized in the consolidated statement of operations. The Company has entered into, and in the future may enter into, interest rate swaps to manage interest rate risk. These instruments may offset a portion of changes in income or expense, or changes in fair value of the Company’s long-term debt. The interest rate swap instruments are designated and qualify as cash flow hedges under the criteria prescribed in ASC 815. The Company records these contracts at fair value on its balance sheet and gains or losses on these contracts are deferred in equity (as a component of comprehensive loss). The fair value of foreign currency forward exchange contracts is determined by using observable market transactions of spot and forward rates (i.e., Level 2 inputs) which is discussed further in Note 13. Additionally, netting provisions are provided for in existing International Swap and Derivative Association Inc. agreements in situations where the Company executes multiple contracts with the same counterparty. As a result, net assets or liabilities resulting from foreign exchange derivatives subject to these netting agreements are classified within other current assets or other current liabilities in the Company’s consolidated balance sheets. The Company’s hedged interest rate transactions as of December 31, 2019 are expected to be recognized within 4 years. 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 13. Interest income or expense related to interest rate swaps is recognized in interest income, net in the same period as the related expense is recognized. The ineffective portions of interest rate swaps are recognized in other income/(expense), net in the period measured. The Company monitors its positions with, and the credit quality of, the financial institutions that are party to any of its financial transactions. As of December 31, 2019, the Company had outstanding hedge contracts for the sale of $288 million and the purchase of $148 million of foreign currencies at fixed rates that will be settled by September 2020. As of December 31, 2019, the Company had no unrealized deferred gains or losses in comprehensive loss related to foreign exchange hedging. As of September 30, 2019, the Company had no outstanding hedge contracts and no deferred gains or losses in comprehensive loss related to foreign exchange hedging. As of December 31, 2019, the Company had outstanding $820 million in pay-fixed receive-variable interest rate swaps with $5 million of unrealized deferred losses in comprehensive income related to the interest rate swaps. As of September 30, 2019, the Company had outstanding $820 million in pay-fixed receive-variable interest rate swaps with $8 million of unrealized deferred losses in comprehensive income related to the interest rate swaps. The realized pre-tax losses and unrealized pre-tax losses of the Company’s foreign exchange forward exchange contracts for the three months ended December 31, 2019 were $1 million and $3 million, respectively. These realized and unrealized losses were recorded in the consolidated statement of operations as other (expense) income. The realized pre-tax gains of the Company’s foreign exchange forward contracts for the three months ended December 31, 2018 were nil. The unrealized pre-tax gains of the Company’s foreign exchange forward contracts recorded in the consolidated statement of operations as other income were $5 million for the three months ended December 31, 2018. The unrealized pre-tax losses of the Company’s foreign exchange forward contracts recorded in other comprehensive income were $3 million for the three months ended December 31, 2018. The unrealized pre-tax gains of the Company’s derivative interest rate swaps designated as cash flow hedges recorded in other comprehensive income during the three months ended December 31, 2019 was $4 million. The unrealized pre-tax losses of the Company’s derivative interest rate swaps designated as cash flow hedges recorded in other comprehensive income during the three months ended December 31, 2018 was $6 million.

Segment Reporting [Abstract]
Segment Information	Segment Information As discussed more fully in Note 1, 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 the summary of significant accounting policies included elsewhere herein. 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 [Abstract]
Additional Financial Information	Additional Financial Information Cash Interest and Taxes The Company made interest payments of approximately $44 million and $42 million during the three months ended December 31, 2019 and December 31, 2018, respectively. The Company paid approximately $20 million of income and withholding taxes during the three months ended December 31, 2019 and paid approximately $7 million of income and withholding taxes during the three months ended December 31, 2018. Dividends The Company’s ability to pay dividends is restricted by covenants in the indentures governing its notes and in the credit agreements for the Senior Term Loan Facility and the Revolving Credit Facility. On December 16, 2019, the Company’s board of directors declared a cash dividend of $37.5 million which was paid to stockholders on January 17, 2020 and recorded as an accrual as of December 31, 2019.

In the first quarter of fiscal year 2019, the Company instituted a regular quarterly dividend policy whereby it intends to pay a modest regular quarterly dividend in each fiscal quarter and a variable dividend for the fourth fiscal quarter in an amount commensurate with cash expected to be generated from operations in such fiscal year, in each case, after taking into account other potential uses for cash, including acquisitions, investment in our business and repayment of indebtedness. The declaration of each dividend will continue to be at the discretion of the Company’s board. Depreciation Expense During the three months ended December 31, 2019, the Company recorded depreciation expense of $24 million, which included a one-time charge of $10 million representing the difference between the net book value of a building and its expected recoverable value.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC 820, Fair Value Measurement (“ASC 820”) defines fair value as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition to defining fair value, ASC 820 expands the disclosure requirements around fair value and establishes a fair value hierarchy for valuation inputs. The hierarchy prioritizes the inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair value measurement is reported in one of the three levels which is determined by the lowest level input that is significant to the fair value measurement in its entirety. These levels are: • Level 1—inputs are based upon unadjusted quoted prices for identical instruments traded in active markets. • Level 2—inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3—inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models and similar techniques. In accordance with the fair value hierarchy, described above, the following tables show the fair value of the Company’s financial instruments that are required to be measured at fair value as of December 31, 2019 and September 30, 2019. Fair Value Measurements as of December 31, 2019 (Level 1) (Level 2) (Level 3) Total (in millions) Other Current Liabilities: Foreign Currency Forward Exchange Contracts (a) $ — $ (3) $ — $ (3) Contractual Obligations (b) — — (1) (1) Other Noncurrent Assets: Equity Method Investment (d) — 38 — 38 Interest Rate Swap (c) — 4 — 4 Other Noncurrent Liabilities: Interest Rate Swap (c) — (11) — (11) Total $ — $ 28 $ (1) $ 27 Fair Value Measurements as of September 30, 2019 (Level 1) (Level 2) (Level 3) Total (in millions) Other Current Liabilities: Contractual Obligations (b) $ — $ — $ (9) $ (9) Other Noncurrent Assets: Equity Method Investment (d) — 40 — 40 Interest Rate Swap — 2 — 2 Other Noncurrent Liabilities: Interest Rate Swap — (13) — (13) Total $ — $ 29 $ (9) $ 20 ______________________________________ (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 purchase obligations and contingent consideration related to the Company’s various 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 included as a component of operating income in the statement of operations. These amounts were mainly calculated using unobservable inputs such as future earnings performance of the Company’s various acquisitions and the expected timing of the payment. (c) The fair value of the interest rate swap is based on dealer quotes of market forward rates and reflects the amount that the Company would receive or pay as of December 31, 2019 for contracts involving the same attributes and maturity dates. (d) The fair value of equity method investment represents an equity method investment acquired in fiscal 2019 whereby the Company has elected the fair value option under ASC 825, Financial Instruments (“ASC 825”). The valuation is based upon quoted prices in active markets and model-based valuation techniques to determine fair value. The following table reconciles the beginning and ending balances of net assets and liabilities classified as Level 3: Total (in millions) Balance at September 30, 2019 $ (9) Additions — Reductions 7 Payments 1 Balance at December 31, 2019 $ (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 months ended December 31, 2019. In addition, there were no observable price changes events that were completed during the three months ended December 31, 2019. Fair Value of Debt Based on the level of interest rates prevailing at December 31, 2019, the fair value of the Company’s debt was $3.096 billion. Based on the level of interest rates prevailing at September 30, 2019, the fair value of the Company’s debt was $3.080 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.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Interim Financial Statements	Interim Financial Statements The accompanying unaudited 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 month period ended December 31, 2019 are not necessarily indicative of the results that may be expected for the fiscal year ending September 30, 2020. The consolidated balance sheet at September 30, 2019 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, 2019 (File No. 001-32502).
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. The Company maintains a 52-53 week fiscal year ending on the last Friday in each reporting period. As such, all references to December 31, 2019 and December 31, 2018 relate to the periods ended December 27, 2019 and December 28, 2018, respectively. For convenience purposes, the Company continues to date its financial statements as of December 31. The fiscal year ended September 30, 2019 ended on September 27, 2019. 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	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.
New Accounting Pronouncements	New Accounting Pronouncements Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”), which established a new ASC Topic 842 (“ASC 842”) that introduces a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. In July 2018, the FASB issued ASU 2018-11, Leases – Targeted Improvements (“ASU 2018-11”), which allows for retrospective application with the recognition of a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Under this option, entities do not need to apply ASC 842 (along with its disclosure requirements) to the comparative prior periods presented. The Company adopted ASU 2016-02 on October 1, 2019, using the modified retrospective transition method provided by ASU 2018-11. The adoption of ASU 2016-02 resulted in the recognition of operating lease liabilities of $366 million and ROU assets of $297 million, which is net of the historical deferred rent liability balance of $69 million, primarily related to real estate leases. The Company also recorded a decrease to opening accumulated deficit of $7 million, net of taxes, related to previously deferred gains related to sale-leaseback transactions. Upon transition, the Company adopted the “package of three” practical expedient provided by ASC 842 and therefore has not (1) reassessed whether any expired or existing contracts are or contain a lease, (2) reassessed the lease classification for expired or existing leases and (3) reassessed initial direct costs for any existing leases. Rather, the Company will retain the conclusions reached for these items under ASC 840. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities (“ASU 2017-12”). This ASU improves certain aspects of the hedge accounting model including making more risk management strategies eligible for hedge accounting and simplifying the assessment of hedge effectiveness. ASU 2017-12 is effective for all annual periods beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted and requires a prospective adoption with a cumulative-effect adjustment to accumulated deficit as of the beginning of the fiscal year of adoption for existing hedging relationships. The Company adopted ASU 2017-12 in the first quarter of fiscal 2020 and this adoption did not have a significant impact on the Company’s financial statements. Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 requires that expected credit losses relating to financial assets measured on an amortized cost basis and available-for-sale debt securities be recorded through an allowance for credit losses. ASU 2016-13 limits the amount of credit losses to be recognized for available-for-sale debt securities to the amount by which carrying value exceeds fair value and also requires the reversal of previously recognized credit losses if fair value increases. ASU 2016-13 will be effective for annual periods beginning after December 15, 2019, and interim periods within those fiscal years. Earlier adoption is permitted. The Company is evaluating the impact of the adoption of this standard on its consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (“ASU 2019-12”). This ASU eliminates certain exceptions to the general principles in ASC 740, Income Taxes . Specifically, it eliminates the exception to (1) the incremental approach for intraperiod tax allocation when there is a loss from continuing operations, and income or a gain from
