Early notice of potential Actual Cost claims. The parties may at any time engage in discussions on any matter likely to result in payments of any Actual Costs and shall use reasonable endeavours to agree whether such Actual Costs arising from the process set out in paragraph 3.3 are likely to arise and/or what mitigating actions should be contemplated to reduce or avoid such Actual Costs. The party initiating such discussions shall provide to the other reasonable evidence in writing of why it considers such Actual Costs will arise and what mitigating actions should be contemplated. Following any agreement or determination that such Actual Costs are likely to arise in connection with one or more future CVL IM Early Notice Possessions or that mitigating actions should be contemplated, the parties shall where reasonably practicable engage in discussions on any options for mitigating costs, revenue loss and/or disruption including any advance compensation for such CVL IM Early Notice Possession(s) to the extent such advance compensation would or would reasonably be expected to facilitate the mitigation of the contemplated disruption. Nothing in this Agreement shall prevent the CVL IM and the Train Operator agreeing any options for mitigating costs and disruption in respect of any CVL IM Early Notice Possession(s). Unless otherwise agreed, the timescales for claiming Actual Costs in paragraph 3.4 shall still apply.
