Thank you.
My next question deals with a news item which was made public on November 22, 2010, concerning helicopters. In fact, it was the Mi-17s. It was the first time I heard about them.
Can you explain to us how this equipment was bought? Why buy Mi-17s when you can buy American helicopters at a lesser cost? Can you justify your decision? What is the mission of these helicopters? Can you also tell us how much it costs to lease them?
