Thank you.
We would start with a recognition that the government's forecasts for the schedule of delivery were not realistic. At the point in time when we were auditing in 2020, we had suggested that the government should use the lessons learned to increase the likelihood of delivery of ships on time.
In terms of the question about what the obstacles were, there could have been many. I do remember, as we were looking at a target state over the course of the two different audits, the challenges for the shipyards to meet targets states were many, whether it had to do with the personnel or the construction of the facilities for that.
Mr. Swales, would you like to add to that answer?
