I would just echo what Mr. Matthews has said.
In our project budgeting, at the early stages, we account for some of this risk. Delays cost money, so there is a significant contingency attached to each project in the early days, and it's pegged down over the years as we know exactly what we're buying and the schedule firms up.
We will continue to monitor that contingency as we see things like the impact of COVID on both of the current projects under way, the AOPS, which are in construction, and the Canadian surface combatant, which is still very much in the design stage.
