I have received a small amount in the individual rights repartition and cannot tell from the information on the specification what it is for.
It is likely that this is a fee from our sister organizations abroad. Pictoright does not always have detailed information about specific uses of your work. Our sister organizations sometimes collect collective copyright fees - as does Pictoright - which they distribute to Pictoright affiliates in accordance with their own policies. Pictoright has no influence on this type of distribution, but according to this method you are entitled to this compensation.
