Thank you, Mr. Chair. So this variable of age and condition seems to be a very powerful indicator of investment. What I see -- my colleague has called up the survey -- is that core housing need in Yellowknife is 17 per cent but the number of retrofits being proposed are 33 per cent. Maybe I could get a better idea of how these different elements are weighted. Do they each have an equal weight, or do they have unequal weights, whatever the weights are? Thank you.
