ACL 2006 holds and manages the head lease from CCC whilst ACL is responsible for operational management of the arena business. IEC was majority owned by ACL.
As I understand it, those 3 companies went in to administration and were immediately bought by House of Fraser Group. Assets won’t be realised for distribution, HoF payment for the three companies is the totality of what is available for distribution to creditors from those 3 companies, There is no need for them to be dissolved and it would be in the new owners interest to maintain all current contracts for use of the stadium in place. But hopefully not Wasps!
