My recollection is that:
Fordham (or whatever the name was at the time) paid City XX million for the image rights, giving an immediate boost to our figures. I think it was about 25-30M, which was a big percentage of the club income.
Image rights then were handled by Fordham in their entirety - PB has said earlier (I think I have this right) that image rights aren't wages, and the club don't have to include them.
The trouble is that Fordham are an ADUG company, and as no-one had done this before in English football, it could be viewed as owner investment, or exceeding fair value. I don't know if it's known what the repayment plan was, if any.
What ended up happening was that UEFA changed the rules of what was covered by FFP, and the revised version included related companies like Fordham; City brought the rights back in-house and collapsed the company.
I don't know how it feeds into the charges.
