Thank you for that question.
As you know, DND is the client and we are the purchaser, so we will respond to what they ask us to purchase. That's the first part, in terms of why we're buying what.
The second part, with respect to the cost and when sometimes we have overruns, is that there are times when there will be certain delays. Shipbuilding and COVID is a perfect example. I heard from Seaspan about the delays from COVID and the resulting labour shortage and supply chain issues.
These things are going to happen, and of course we always want to be responsible as we move forward. We always want to be monitoring. We want to work with suppliers to do the best we can to ensure the projects come in on budget and on time.
