Their forecast will be based upon what they have actually spent to date, and what they think they have left to spend. You then compare that to the Prices to see where you are, although the Prices will NOT yet include un-agreed CE's but they will be within the forecast. Whether or not you agree these are a CE that will change the Prices it is a cost they will incur. For that reason the quicker both Parties can get compensation events to be implemented the better as the forecast compared to the Prices will be more transparent as to liability.
Obviously the pain/gain calculation is only done at the end when the Prices including implemented CE's are agreed and the costs are all now in and auditable.
