Thank you, Mr. Chair. The way the environmental liabilities work for our own sites is we have a listing of all of the GNWT sites with liabilities. We have a liability fund of about $48 million that is put away to clean up those sites. The $2 million that you see in the main estimates reflects the changes on an annual basis that we would expect to happen as we either get better estimates of costs or that we clean up things or adjust them or, frankly, as new sites are identified and those sorts of things. The $2 million is actually almost like a debt value, if you like, because there may be negative adjustments as well as positive adjustments. It really is how we adjust that $48 million liability fund as we clean up things and also then as we identify new sites or get further detailed estimates on the cost of cleanup and that sort of detail. Thank you, Mr. Chair.
