"The Appellants' case is that Ofcom has made a material error in the setting of that price control by deciding not to allocate common costs away from TI services in proportion to all forecast customer migration, rather only in proportion to forecast customer migration from TI services to Ethernet services... Ofcom should also have removed from the TI services basket a proportion of common costs which reflected migration to services other than Ethernet..."
"The second point is more specific to this particular appeal, which is that one of the implications of the Vodafone/Verizon appeal is that it is concerned that the TI services are not picking up these common costs. They should be going, in particular, to other services and including services that my clients buy in very large quantities, namely LLU, WLR services... So we are concerned in that context to protect our interest to ensure that no findings are made, or anything is established by the Competition Commission, that would lead to the conclusion that the appropriate place for those costs to end up are the services that we are purchasing because we say that the cost of those services already reflects an appropriate apportionment of those costs."
