why is it going up, page-38

I think those that see the WTG claim as related to WIP are barking up the wrong tree. PSD wasn't bought for the work on its books, a temporary objective that would largely be complete in two years. It was bought for the businesses that collectively are PSD.

I'm more inclined to think the claim's base is in contracts: employees, suppliers, affinity partners and possibly recievables/payables. That would make more sense to me. It is hard to imagine how could successfully claim against work not leading to a settlement when the defendant (WTG) has no control over that work. I could envisage a situation where there was some sort of assurance around performance and staying of key employees plus assurance over IT systems plus assurances over performance of supplier/affinity groups / relations with insurers. All of those factors would take a while to surface and not necessarily down to how SGH handled them (unlike proving some problem with an inherently risky WIP file that WTG and no part in post PSD).

Whatever it is, I think it must be on a sound footing. If you were to hang your hat on anything it would be a law firm knowing they have a justifiable claim. S&G would be the last outfit one would expect to casually 'what the heck let's give it a go'!
