So this particular tweet (from Stefan) relates to City's Etihad sponsorship deal which was a key part of the APT case. The crux of this issue is the PL's reliance on a Fair Market Value (FMV) assessment of City's Etihad deal produced by Nielsen which was significantly below where City has valued it. But City also relied on a Nielsen assessment (in 2021) which used substantially the same method. The PL's key decison-maker (Mai Fyfield, non-Exec Director) was aware of City's valuation from Nielsen and obtained an explanation of the differences from Nielsen.
As I understand, the Tribunal judgment covered the following:
1. They did not assess whether City's or the PL's valuation was correct. Instead they concluded that it was not unreasonable for Fyfield to rely on Nielsen's explanation of differences and arrive at her FMV decision. So this aspect of City's complaint was not upheld.
2. PL in its FMV assessment relied on a benchmarking analysis prepared by Nielsen. The Tribunal upheld City's complaint that they should have been shown this analysis and allowed to counter it and deemed this to be procedurally unfair.
3. More generally, the Tribunal opined that the concept of APT rules is not illegal but the rules as currently drafted are unlawful. In particular, they upheld City's assertion that loans from company shareholders should be included in APT assessments - in other words, Shareholders (owners, non-executive directors) are Associated Parties. This matters because at least 9 clubs receive such Shareholder loans that are at zero/low interest rates - in other words off-market rates. If you re-assessed those Shareholder loans at FMV, many of these clubs could fail PSR - which is the point Martin Samuel eloquently makes.
4,. This has given rise to a new food fight where the PL claims they can just tweak the current rules (e.g. add in Shareholder loans) whereas City state that the rules are unlawful so have to be discarded and re-done from scratch (and are threatening legal action if PL attempts to short cut things). Additionally, any changes to APT rules would need to be affirmed by at least 14 clubs. If 9 are depending on Shareholder Loans, they may well not agree.
5. On Shareholder loans, there is a separate fight over whether they are added in for future assessments (PL's stance) or whether all old deals need to be re-valued (City's stance). The latter would be especially problematic for clubs who might then retroactively fail PSR for prior years. Opening a major can of worms.
6. Tribunal also rejected City's claim that the APT rules were brought into disadvantage Gulf-owned clubs.
Anyway, that's my reading of things. Great minds of Bluemoon, please correct if I got anything wrong!
