UPDATE 14.08.13: We are currently in talks with PRS and others on this complex issue and will report back to you when we have further detailed information.
We have been made aware of a practice that has been occurring in The Netherlands for maybe 10 years which has recently come to light. It affects larger acts more but the principles are the same for all our members.
As you know the performance right for songs is licensed by collecting societies to venues and promoters. Typically a % of box office receipts (3% in the UK); the rates vary in Europe.
The rate in Holland is 7% of box office for gigs with an income of €1,000,000+. This figure has been used when accounting to agents, promoters and bands. However promoters have been receiving a rebate of the published rate from local collecting society BUMA/STEMRA and not accounting this to artists.
PRS are aware of this and have had discussion with BUMA to make the process more transparent:
BUMA has published its live tariff on its website (including the fact a discount is available) and is itemising any discount applied on its invoices.
