I don't have that figure with me, but I will start by saying that the increased traffic qualification perhaps is overstated today. There's no doubt that at some point we're going to have to look at what assets we have to serve and address the increased risk associated with increased traffic.
For the last two or three years, traffic in the north has gone from 250 to 350 voyages, compared to millions of voyages in the south. It's not a huge increase. There is no doubt though that with increased activity in the north that may increase in the future.
