It is true that we are continuing to work with the other JSF partners to develop the sustainment process. There's been a series of sustainment war games ongoing through these months to that end, and it's anticipated that over these months we will get a clearer understanding of the nature of the collective sustainment process.
However, we do have initial estimates, and from those initial estimates it appears that the cost of sustainment of an F-35 for Canada would be approximately the same as what we're paying currently for our fighter capability.
