Thank you, Mr. Chairman. The reason for that is when the negotiations were going on for an environmental agreement among Diavik, the federal government, the Government of the Northwest Territories and the aboriginal governments from the impacted communities, it was recognized that there were some initial set-up costs that were over and above what the federal government and Diavik were willing to contribute. So the Government of the Northwest Territories and Diavik agreed to cost share start-up costs for the first year. It was a one-time, one-year cost. So that's why it's falling off this year, because it was for two years. After that, it was no longer a requirement because the expectation is the participants would be fully trained and the start-up costs would no longer be required.
