How is the first performance supplement registered and calculated?

All new works that meet the criteria for first performance will automatically be given a special code when a work notification has been submitted and registered. This code is triggered the first time the work is chosen for performance, and the payment due is determined as part of a separate first performance distribution that takes place in the December of the year after the actual performance.

This means that you do not need to report the first performance separately.

The first performance supplement is based on the distribution payable for the original performance. This amount is multiplied by a so-called first performance factor.
