I don't know the actual schedule of block IV. That's a great question. Finland, of course, will be entering into it. My colleague Mr. Fergusson noted what's to be negotiated. I think one of the key things to negotiate with the company is where in the production cycle we fit. They have a certain production rate of x number of aircraft. The Americans get so many, and many of the other partners get so many.
I don't know if my other colleagues would like to chime in.
