Thank you, Mr. Chairman. Mr. Chairman, there would be times when we look at the market and the price would either be in a general increase and that would be the time we would look at using this tool to buy fuel or gasoline on future markets, so that if we look at the trend, the trend would show it's going up. If our re-supply is happening in, say, six months' time and the price seems to be going up, we can make a decision to buy at that price for that future time to be delivered. At the same time, we could see the trend would either be levelled off or maybe going down, we would say let's not use this at this time and wait for that. The spot market might be better than it is at the day when you look at making a decision like this. So it's not something that you would do at every time we go for re-supply, but we would be watching the market, the trend. If the prices are continuing to climb and we know we're getting to a heavy time of year for use of products, usually the price of those products climbs accordingly. We would, at that point, look at using this instrument to buy out there and hopefully have a savings when it's delivered. Thank you.
