CoS Objection Process Review At the last IGG meeting we presented: Key features of current process Three alternative process options Some feedback was received from Market Participants. General preference for Option 3. 9

CoS Objection Process Review Details of Option 3 as follows: Option - All validated objections will go through unless New Supplier objects within time limit Pro: Reduces risk that valid customer objections can be blocked whilst keeping open the option for the new Supplier to counter-object Con: Cost and risk of changing process & systems Risk of unwarranted objections Would additionally require an arbitration procedure to handle counter objections 10
