Mr. Chair, when we have received submissions from the Department of National Defence concerning the timeframe for the costing of a life cycle, 20 years has been deemed to be an appropriate timeframe. It is set by the Department of National Defence.
Going beyond 20 years is considered too high-risk to ensure that the value in contracting with industry would be sustained, or the costs would be going beyond the 20-year mark. So that, for us, is considered to be reasonable, and as the Deputy Minister of National Defence indicated, all of the submissions to date that have been presented to the Treasury Board have used a 20-year cost estimate.
