Mr. Chair, I just want to get back to another question about the variability of methodologies. There is a high degree of variability of projected costs for differences in assumptions and methodologies for various studies. I won't get into the detail of that, but I'll just state that.
On your question of a target, I'd have to check. I don't have information on a specific target that we have established. If you could let us know where you sourced that, we can get back to you on that.
