I will take a stab at giving some numbers.
If we look back now at the first seven or eight years of CFI's existence, we see that because there had been such a deficit in infrastructure in universities, the percentage of the total federal research investment, as you've put it, that went into infrastructure averaged 27% of the total. Two years ago when we were making our presentations, we said that we thought 20% now would be sufficient, and that is to both sustain the investments at state-of-the-art level and ensure that we can continue to invest in new facilities, but some of the back-up, the catch-up, had already been done.
That figure, interestingly, we arrived at by looking at Canadian needs, but it turns out that it is very much in keeping with what other countries are doing. In the U.S. it's 22% to 27%, in Australia 20%, and in U.K. 22%. So for what that's worth, compared to other countries, it's something in the order of 20%.
And without going into the detail, you might say, how did we get there? We looked at costs, what the depreciation is, the scientific depreciation on the equipment and the infrastructure, and what it will cost per year to maintain it at state-of-the-art level. So that was the sustainability fees, and then we added in what we anticipated would be needed for new emerging areas in which we had not previously invested.
It's a very crude calculation, but it's an attempt to answer your question.
