Nope. UFC doesn't release financial statements, which is pretty standard for a company of its size. But you can glean this much by listening to Mr. Fertitta's public statements and checking them against publicly available information regarding UFC's transactions. It should be rather self-evident given the UFC's rapid expansion in the last few years. We know approximately how much UFC is worth, and its debt-income ratio. There was an article about in Forbes I believe (or some other econ magazine). You can extrapolate from there without needing to see its balance sheet and income statements.
Bottom line is that UFC pays what is fiscally responsible given its liabilities. You can see what happens when a company cuts too deeply into its liquid assets in order to appease the short term interests of fighters (Affliction). One small setback can sink the entire company. The companies that survive are structured to absorb the occasional (or inevitable) shit storm. As to UFC, what some people are calling "greed" is just boilerplate fiscal sanity.
Major props on the post
I am someone who was in a major union for 15 years & owned a business for 10 (same time), so I get both sides.
Too many have no idea of the business end & what it takes to stay solid.
Could Zuffa pay fighters more? = of course
Are Zuffa paying slave wages, etc.? = no
Was the Reebok deal handle correctly? = NO WAY
Have fighter salaries risen at a large rate? = yes
Plus UFC has 600 fighters they pay medical for & the bottom 300+ are making 10x more than they would elsewhere.
Like most companies there is good with bad & because of Dana's desire to act like a dick (a lot), people microscope the bad.
Also people still insist that the AC reported pay is what fighters make & refuse to acknowledge that fighters themselves admit they have made more money undisclosed to AC than AC disclosed.
Unions are fantastic to improve bad working conditions & things like no over-time, etc.
Those are not issues with UFC.
If UFC gets bigger (which I don't see happening in a large way) then things like likeness rights, etc. will be bigger issues IMO
