The Company classifies its business interests into two fundamental operations: Recorded Music and Music Publishing. A brief description of these operations is presented below. Recorded Music Operations The Company’s Recorded Music business primarily consists of the discovery and development of artists and the related marketing, distribution and licensing of recorded music produced by such artists. The Company plays an integral role in virtually all aspects of the recorded music value chain from discovering and developing talent to producing albums and promoting artists and their products. In the United States, Recorded Music operations are conducted principally through the Company’s major record labels—Warner Bros. Records and the Atlantic Records Group. The Company’s Recorded Music operations also include Rhino, a division that specializes in marketing the Company’s music catalog through compilations and reissuances of previously released music and video titles, as well as in the licensing of recordings to and from third parties for various uses, including film and television soundtracks. The Company also conducts its Recorded Music operations through a collection of additional record labels, including, among others, Asylum, Big Beat, East West, Elektra, Erato, Fueled by Ramen, Nonesuch, Parlophone, Reprise, Roadrunner, Rykodisc, Sire, Warner Classics, Warner Music Nashville and Word. Outside the United States, Recorded Music activities are conducted in more than 50 countries primarily through various subsidiaries, affiliates and non-affiliated licensees. Internationally, the Company engages in the same activities as in the United States: discovering and signing artists and distributing, marketing and selling their recorded music. In most cases, the Company also markets and distributes the records of those artists for whom the Company’s domestic record labels have international rights. In certain smaller markets, the Company licenses the right to distribute the Company’s records to non-affiliated third-party record labels. The Company’s international artist services operations also include a network of concert promoters through which it provides resources to coordinate tours for the Company’s artists and other artists as well as management companies that partner with artists on other aspects of their career such as merchandising, fan clubs, endorsements, as well as appearances and sponsorship. The Company’s Recorded Music distribution operations include Warner-Elektra-Atlantic Corporation (“WEA Corp.”), which markets and sells music and video products to retailers and wholesale distributors in the U.S., Alternative Distribution Alliance (“ADA”), which distributes the products of independent labels to retail and wholesale distributors in the U.S.; various distribution centers and ventures operated internationally, an 80% interest in Word, which specializes in the distribution of music products in the Christian retail marketplace, and the Company’s worldwide artist and label-services organization, including ADA Worldwide, which provides distribution services outside of the U.S. through a network of affiliated and non-affiliated distributors. In addition to the Company’s Recorded Music products being sold in physical retail outlets, Recorded Music products are also sold in physical form to online physical retailers such as Amazon.com, barnesandnoble.com and bestbuy.com and in digital form to online digital download services such as Apple’s iTunes and Google Play, and are otherwise used by digital streaming services such as Beats Music, Deezer, Rhapsody and Spotify, and digital radio services such as Pandora, iTunes Radio and iHeart Radio. The Company has integrated the sale of digital content into all aspects of its business including Artist & Repertoire (“A&R”), marketing, promotion and distribution. The Company’s business development executives work closely with A&R departments to ensure that while a record 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. The Company also works side-by-side with its online and mobile partners to test new concepts. The Company believes existing and new digital businesses will be a significant source of growth for at least the next several years and will provide new opportunities to successfully monetize its assets and create new revenue streams. The proportion of digital revenues attributed to each distribution channel varies by region and proportions may change as the roll out of new technologies continues. As an owner of music content, the Company believes it is well positioned to take advantage of growth in digital distribution and emerging technologies to maximize the value of its assets. The Company is also diversifying its revenues beyond its traditional businesses by entering into expanded-rights deals with recording artists in order to partner with artists in other aspects of their careers. Under these agreements, the Company provides services to and participates in artists’ activities outside the traditional recorded music business. The Company builds artist services capabilities and platforms for exploiting this broader set of music-related rights and participating more broadly in the monetization of the artist brands it helps create. The Company believes that entering into artist services and expanded-rights deals and enhancing its artist services capabilities will permit it to diversify revenue streams and capitalize on revenue opportunities in merchandising, fan clubs, sponsorship, concert promotion and touring. This will provide for improved long-term relationships with artists and allow the Company to more effectively connect artists and fans. Music Publishing Operations Where recorded music is focused on exploiting a particular recording of a composition, music publishing is an intellectual property business focused on the exploitation of the composition itself. In return for promoting, placing, marketing and administering the creative output of a songwriter, or engaging in those activities for other rightsholders, the Company’s Music Publishing business garners a share of the revenues generated from use of the composition. The Company’s Music Publishing operations include Warner/Chappell, its global Music Publishing company, headquartered in Los Angeles with operations in over 50 countries through various subsidiaries, affiliates and non-affiliated licensees. The Company owns or controls rights to more than one million musical compositions, including numerous pop hits, American standards, folk songs and motion picture and theatrical compositions. Assembled over decades, its award-winning catalog includes over 65,000 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, gospel and other Christian music. Warner/Chappell also administers the music and soundtracks of several third-party television and film producers and studios, including Lucasfilm, Ltd., Hallmark Entertainment and Disney Music Publishing. Since 2012, Warner/Chappell has been making an effort to augment its film and TV music business, with the acquisitions of certain songs and recordings from numerous critically acclaimed films and TV shows. These acquisitions will help Warner/Chappell take advantage of the higher margins and strong synchronization and performance income in the TV/film space. The Company’s production music library business includes Non-Stop Music, Groove Addicts Production Music Library, Carlin Recorded Music Library and 615 Music, collectively branded as Warner/Chappell Production Music.
