Jimmy_C in one of his earlier posts made an estimate of approx 40% of revenue was paid out by PRT in affiliation agreements.

I'd say that this is about right.

Looking at the FY 17 statement and a rough calculation:

Revenue: 240,059
Operating Exp. 50,047 (Broadcast and Admin)
Wages and Ben. 39,058
Borrowing costs 2,328
Tax paid 13,661
Invest. Activities 2,428
Dividends 12,456
Debt repaid 28,619

etc.... Leaves a tad over 90m unaccounted for so would assume that this is what gets paid to its affiliates, ie. approx 40% of revenue. I guess that we also need to assume that not all revenue is associated with PRTs affiliates as some revenue is on the back of their own content production (local news etc) so 40% could be at the lower range and may in fact be slightly higher.
