Thank you for the question.
I would just like to point out that waste that is not disposed of in the United States and that is just in transit is subject to our regulation and does require an export permit. We track and monitor the material that is transited through the United States, and when it's destined for a party that is a member of the Basel Convention it's also excluded from our arrangements with the United States. The company wanting to do so would require an export permit prior to the export, and this requirement is, again, one of the elements of our being able to and having accepted the Basel amendments.
I'll turn to Nathalie Perron to see if she has further information to add.
