Under the current contract, the Commercial Rights Holder is obliged to pay the teams a fixed percentage of its turnover. However, early this year before Covid became a huge problem, Liberty projected what their turnover for the full 2020 season would be and how much of that would be paid to the teams. To Liberty's credit, more recently they said that they would pay out that projected amount, notwithstanding that their turnover is likely to be far less than what was expected at the time of the projection.
Ah, I didn't realise that they were paying the full (from the projection) amount. That's really good for the teams.
