Collection shares and ownership shares
All music publishing incomes are split between the songwriters and the publishers according to terms of their agreement.
This is typically referred to as the “writer share” and “publisher share”. The relative percentages of this split compose the ownership shares.
There may be more than one publisher involved in the ownership of a composition, hence the ‘Controlled’ flag (y/n).
Global sum of ownership shares (controlled and not controlled) is 100%.
The publisher collects the royalties on behalf of the controlled writers and publishers according to their agreements (collection shares, maximum 100%).
