Did SISU not look at ACL's books and say they were not viable and not worth buying?
They did due diligence on ACL and apparently found it wasn't worth paying the set formula price for the Higgs shares. Since then ACL did some cost cutting and business development exercises that kind of imply sisu were right?
Funny thing is if sisu had bought the ACL mortgage at distressed value they might have got a discount big enough to justify paying Higgs over the top for their shares.
