A reciprocal agreement is a formal arrangement between two or more collective management organisations (CMOs) in different countries that allows each society to collect royalties on behalf of the other’s members within its own territory. These agreements are the backbone of international royalty collection.
When your music is broadcast, performed, or streamed in a foreign territory, the local CMO in that country collects the royalties owed. Through its reciprocal agreement with your home society, it then transfers those earnings back to your PRO, which pays them through to you.
Reciprocal agreements exist across both the publishing side (between PROs like ASCAP, PRS, GEMA, SACEM, SIAE, Autodia) and the master side (between neighbouring rights societies like PPL, GVL, SoundExchange). The scope, speed, and accuracy of these cross-border transfers vary significantly between territories and between societies.
For composers, the practical implication is straightforward: your works need to be correctly registered with your home society, and your home society needs active reciprocal agreements in the territories where your music earns. Without both, international royalties can go uncollected.
