It depends if the club plans to borrow against it.
The full 12m can boost year 1 PSR accounts, but the instalments arriving in years 2 and 3 don’t give extra PSR headroom. Spending that cash later counts against PSR for those years, which can then be restrictive. That’s why clubs sometimes borrow against future instalments in Year 1
if they don’t, it’s better to align revenue with cash flow to reduce net profit.
