From elsewhere, where it's explained better.
Operating loss is mainly because: our broadcasting rights were stolen, sponsorship income was paltry because of the uncertainty/league, season ticket prices were reduced, and we had several one-off costs like football debts. None of these are recurring.
I'll try and simplify the negative goodwill. Sometimes you need to pay over the odds for a business that you really want. It's worth £100k but you pay £130k. However sometimes you manage to buy a business for less than it's worth because of circumstances, such as the owner needs to sell. You might buy a business for £80k but it is worth £100k (the "fair value" of its assets). This is what has happened here. That £20k you underpaid is a profit in a sense and you recognise that profit in the accounts. CG got the brand "Rangers" (and players etc) valued and the "fair value" was some £20m higher than he paid.
Don't confuse this with the revaluation of the properties that also took place. The properties were valued at £34m more than was paid and their values have been uplifted to reflect this. If they were sold at that amount, there would be £8m tax to pay, and that "deferred tax" liability has also been provided, hence a net increase in the balance sheet of £26m (the "revaluation reserve").
