We don't try to make a huge profit. How we ultimately judge how we're doing financially is whether or not we had to raise our charges to our customers. I can sit here today and tell you that we have not done that for eight years. In fact, over the last eight years we've reduced them twice.
At the same time we've made some pretty substantial investments in technology, and so on. We've gone through some pretty severe downturns in terms of traffic, which of course reduces our revenues, and we've still not raised those rates. We've managed to find innovative ways to run the business and to introduce new technology without doing that.
