I will begin by answering your questions. Afterwards, Paul can talk about the impact because he is currently in negotiations.
I have an IBR contract with Pratt & Whitney Canada. The field is competitive. People from Italy, France and around the world manufacture engines or parts. Companies like certainty. They like to know that the future will not bring changes. So, in the case of a country that has already signed a contract, the companies that want to continue working will just say they know that that country will buy airplanes, but they do not know whether that other country will. They will gauge their chances of working in those other countries.
Paul, would you like to add something?
