Thank you, Chair.
Each department...and I'll perhaps mention CRA, because I think we noted in the report that they do this in quite a rigorous fashion. They go through and identify all of the improvements or changes that they think will be required over the next while; I think it's a five-year plan that CRA has, five- or ten-year plan. Then they go through a prioritization to see which ones are critical to the continued sustainability of their systems.
It's really a way to prioritize and to accord importance to the various changes that they see in their investment plan.
