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.
