I'm not entirely sure of the numbers you are referring to, Madame Pauzé. But if the inference is to why the costs of the legacy waste liabilities are going up with time, the reason it that as we undertake work to address the legacy liabilities and we start digging into the ground to better understand what's there, because many of these liabilities date back to the 1940s, 1950s and 1960s, our records were not complete. As we start to address those legacy liabilities, we learn about the actual conditions and we are more informed about the cost of remediating the environment to address those legacy liabilities. For that reason the costs have gone up.
This is consistent with what we see in other countries, like the U.K. and the U.S. As they start to address their legacy liabilities from 50, 60, 70 years ago, they see their costs going up as well. The fact is that the actual legacy liability is going down with time as CNL executes the environmental remediation.
