Based purely on available information, including the RFL statement in the T&A this morning, if the directors do NOT announce proceeding to administration today, then my speculative guess has to be that they are more worried about the consequences of administration for the future of the club than they are about a winding-up order from HMRC. And are prepared to lose the creditor protection moratorium and take their chances in the face of winding up proceedings being instigated, rather than risk the consequences of administration. It would also suggest that matters have not proceeded as planned.
Or, alternatively (and there is always hope) they are sufficiently confident of raising the necessary funding to be able to accept losing creditor protection for a short period, the two week moratorium having bought time. Maybe.
Conversely, if they DO proceed to administration, they must presumably judge the risks of administration - including any threat to the SL licence and of key players becoming free agents and being recruited by others, to be manageable or acceptable. That would suggest to me a prepack being in place or imminent, and the nod having already been given by the RFL.
But all pure speculation, in the absence of any real hard facts anywhere, so in 12 hours this may just read as so much more out of date off-beam speculative guessing!
