A couple of things. I havent got a clue how they have got to £60m, sounds ridiculous. The figures everyone wants to know is how much SISU are actually owed, whether this is debt or equity investment, how much ARVO have invested (sounds like its £8.4m) and whether this is fully secured.
The lack of transparency is frightening. I dont believe the figures they are quoting unless there are huge management charges, pay offs etc. It would be up to an Administrator/Nominee of a CVA to conclude the voting values of all parties. I believe ACLs final claim could justifiably be tens of millions as mentioned above
Either way the Administrators job is to maximise realisations ie accept the best offer available for all creditors.
