There are no arrangements or understandings between Mr. Levin and any other persons pursuant to which he was appointed as the Company’s Executive Vice President and Chief Financial Officer. There is no family relationship between Mr. Levin and any director, executive officer, or person nominated or chosen by the Company to become a director or executive officer of the Company. The Company has not entered into any transactions with Mr. Levin that would require disclosure pursuant to Item 404(a) of Regulation S-K under the Exchange Act.

Pursuant to the terms of an employment letter, dated September 30, 2014, by and between Warner Music Inc., a wholly-owned subsidiary of the Company, and Mr. Levin, for his service as the Company’s Executive Vice President and Chief Financial Officer, Mr. Levin will receive an annual base salary of $550,000, be eligible to participate in the Company’s bonus plan, with an annual target bonus of 60% of his base salary, or $330,000, to be earned based on factors including the strength of his performance and the performance of the Company, and be eligible to participate in the Company’s U.S. benefits programs, subject to the terms and conditions of each program, and as described in the plan documents and summary plan descriptions.
