Thank you.
Of course, as a common carrier, we have an obligation to move all commodities that are offered to us. Grain is a very large and important commodity for us. Twenty-four per cent of our revenue is associated with grain, so it's a very important one for us but so are the other commodity groups.
It is a daily balancing. We are really managing supply chains with our customers. Just as certain supply chains require surges in service, for example, to meet a vessel or satisfy a sale, we're balancing all the time with the shippers we're dealing with. Really, our objective is to provide sustainable, balanced service to all of the commodity groups. Certainly, we're cognizant of what our shippers are requiring on a day-to-day basis, to make sure that we are meeting their demands as fully as possible.
