I guess the point is that the owner is off the hook for at least ten million pounds - and it gives them a bit of a lift short term. It also takes away the risk that the Council are forced to pull the plug on the ACL loan as the result of SISU's court battle.
From that point of view the owner has played a blinder here.
I don't think it makes Wasps a much safer bet long term though, they've now got a huge debt to service, alongside a rising salary cap, substantially funded by a television deal that is yet to show it's sustainable in the long term (rough viewing figures for Prem Rugby in the low hundreds of thousands per game, for Prem football, into the millions).
It's very exciting for Wasps, but I can see plenty of risks in their business model. I wonder if SISU might consider a bond issue to fund CCFC and/or a new stadium on the back of this!
