I sure hope that's not how the management decides transfers.
So those are the basic parameters and is how the management looks at the books - rather than just looking at transfer fees on their own.
Reality is, we could spend a lot more. Reason why they use bonuses as a %age of the total is it helps the accounting. For example, 40+10 for a 5 year contract means you amortize at 8m vs 10m. If bonuses are triggered its usually commensurate with higher revenues from winning trophies, prize money etc.
