Warner/Chappell president Rick Shoemaker is exiting the publishing arm of Warner Music Group at the end of March.

The company didn't offer specifics as to the reasons behind Shoemaker’s departure. However a source close to Warner/Chappell said that the shakeup is believed to be a result of "strategic differences" between the veteran executive and new chairman/CEO Richard Blackstone.

Shoemaker has held the post of Warner/Chappell president for the last decade. He was closely aligned with former Warner/Chappell chief Les Bider, who left the company last year.

In a Feb. 23 memo Warner/Chappell staffers, Blackstone said that the company will be naming a Los Angeles-based successor to Shoemaker in the near future.

Warner/Chappell will continue to operate its U.S. operations out of L.A., while the company’s global operations are housed in New York.

The company controls publishing for more than 1 million copyrights, including the songs of Cole Porter, the Gershwins and a roster of such artists as Madonna, Dr. Dre and Sheryl Crow.
