Well one thing we can guarantee is that the loan is no longer in play, as it was to FPP Sunderland LLP. If that company no longer exists, then the charge will be removed shortly and it must have been satisfied. The loan charge can't exist without a company to be paid to, so it has been resolved.
The only way this can mean FPP still buy us is if for some reason they wanted to satisfy this as part of the deal to buy SAFC.
I can't think of any obvious reasons, but I can ask the mrs tonight if there are any minor tax advantages to it, as she gives tax advice in these exact situations for one of the big 4. I doubt it though, and even if they were, FPP would have purchased Madrox and absorbed it into their group rather than winding up FPP and becoming directors of Madrox. Getting rid of FPP as an entity probably signifies this one is dead.
