What I can tell you is that the agency spends approximately $100 million a year towards the improvement of these systems. It varies from system to system, obviously.
Some of the $1 billion is towards developing certain systems to have better business intelligence, for example. There are portions of money there. What we do at the agency is manage the funding in a portfolio, and there are decisions made. There's a process every year by which we decide which systems are in need of improvements or have sustainability issues.
We spend in the neighbourhood of $100 million a year on these systems.
