The amended statement of claim under the IPFA seeks damages against AECL for negligence and breaches of the IPFA, among other things, during design and in construction supervision and quality assurance. The damages claimed are for the recovery of Nordion’s costs up to the end of the IPFA, net of certain amounts settled between Nordion and AECL at the time of entering into the ILTSA.The parties have agreed on a preliminary schedule for proceeding in the IPFA claim that provides for the filing of the amended statement of claim by Nordion at this time. The schedule then provides for AECL to file motions if it sees fit and to file a defence. Documentary productions and discoveries are currently anticipated to begin during 2013. Based on the current schedule, the matter would not be expected to be set down for trial before mid-2014. Nordion legal costs associated with MAPLE arbitration cost determination and the pursuit of the IPFA lawsuit against AECL currently are expected to be approximately $2 million in fiscal 2013.
