That was the most worrying thing for Mags fans. You only put a provision in where the expectation of having to pay up is higher than the possibility of non-payment. I'd have expected the note of a contingent liabliity, noting a risk that's less than 50% likely to arise.
Minor technical note: it was a provision, not an accrual. An accrual is a recognition of an existence of a liability, which is known, but no yet invoiced by a supplier (like a proportion of the next gas bill). A provision is an estimate of a liability likely to arise, but not yet quantifiable with 100% accuracy.
