Horizon did negotiate some huge deals and so they were owed something. Whatever the dispute they did carry out their role and were owed a decent sum. The question to be decided was how much. I read it Rory paying an agreed amount to Horizon, from his point of view hopefully less than the contract figure from theirs the contract figure. Logic says somewhere inbetween.
No doubt who paid who and who came out of it better will seep out over the next day or two. Both will look to claim victory.
