On shipbuilding, there are two very interesting dynamics with respect to the pandemic.
One is that because of the economic stability of continuing to be able to build ships during the pandemic period, hardship or not, we actually saw statistical growth in the defence sector. In 2020 the sector, predominately buoyed by shipbuilding and the ability to continue to build ships, grew by $2.2 billion in GDP and 13,900 jobs. That's a testament to the fact that when you have something that's economically stable in an environment like a pandemic, which is a snap shock, it is quite good for economic stability.
That said, in terms of the NSS itself and its costs, you heard the shipbuilders say there are long-term ramifications in labour shortages and cost escalations that come from supply chain issues. We are seeing those, and not just in the NSS. We are seeing it across the sector in general. I believe that business in general is seeing it. We've heard escalations, for example, of up to 400% in certain supply chain areas, so there are long-term ramifications. As I said, even though these programs are for 10 years, it will be very hard in the short to medium term for these businesses to absorb those losses without some kind of management from a programmatic perspective.
Our worry is that we certainly don't want to see the number of ships get cut, for example, in order to accommodate things like inflation or labour shortages, which increase wages.
