ACUM is a non-profit corporation administering the rights assigned to it by its members – authors, composers, lyricists, poets, arrangers and music publishers. The rights administered by ACUM include performing rights, mechanical rights (audio and audio-visual reproductions), reprint rights and, partly, “grand rights”. By its reciprocal representation agreements ACUM also administers these rights- fully or partly on behalf of hundreds of thousands members of 107 affiliated Societies from all over the world. ACUM was established in 1936 by a small group of leading authors and composers, and has now a membership of ca. 4,000 creators and publishers. ACUM's Board of Directors consists of 7 members - 3 authors, 3 composers and 1 publisher- elected by the full members for a two year term. The board members may be reelected without limitation. ACUM is an ordinary member of CISAC (International Confederation of Societies of Authors and Composers), and of BIEM (International Bureau of Societies administering Mechanical Rights).
