I don't get that "non-fraudulent" bit. Company was found to owe £15m or so in VAT due to fraud, so company is liable. So not sure why there might be good money as well as bad. Plus from a quick skim of the liquidator's report, seems like money may have been taken out of the company fraudulently, so claims against the directors responsible.
Report also shows how to take money out of the company legally, ie £6m-ish in liquidators and legal fees. Plus a £100/hr fee increase for partners working on this case. That's always struck me as a problem with our liquidation process, ie a company might be salvageable, if not for the fees charged.
