What was time barred was anything prior to the CAS-imposed cut-off date, which was 5 years prior to the filing of charges (which effectively was anything up to and including our 2013 year end accounts. Anything in the 2014 accounts and beyond was in scope.
On the basis that the PL haven't (as far as we know) charged us with anything as yet, and the assumption that a 6-year UK Statute of Limitations will apply, then if they charged us tomorrow, they couldn't legally look at anything that happened prior to 9th May 2016 in theory. So that might be the 2015 accounts and prior years (as May 2016 would fall within the 2015/16 financial year).
We also know from the CAS ruling that the CFCB case concerned the Etihad & Etisalat sponsorships, which started prior to the cut-off date but continued beyond it and are still in place today. So if ADUG had been providing the money for these sponsorships during or after the 2013/14 financial year then they would have been able to look at that. However it was quite clear that it was the Abu Dhabi Executive Council, not ADUG, who were supplying the funds to Etihad (not us, which was the point of some of the emails). The sponsorships were never owner funded so the time-barring claim is a complete red herring.
What also just occurred to me is what exactly the PL are looking at? Their financial rules are very different to UEFA's FFP rules and merely concern looking at losses, which are allowed to total £105m over 3 years. I think these rules only came into force in the 2015/16 season. The only thing I can think of that they're looking at is whether we would have broken their rules (not UEFA's) if sponsorship was artificially inflated. We know it wasn't so I struggle to see how they'll come up with any charges unless they have a smoking gun that UEFA/CAS didn't have.
