According to its mission, "ASCAP is committed to protecting the rights of its members by licensing and collecting royalties for the public performance of their copyrighted works, and then distributing these fees to the Society's members based on performances."
ASCAP's board of directors is made up solely of writers and publishers, elected by the membership every two years.
