What that means is that when we save money, because our tax bill goes down, we have more cash to expand. The analogy would be the following. Let's assume it costs us $100 million to run a high-speed rail line between Toronto and Montreal—albeit, it obviously costs significantly more than that. But if we spend $5 million a year, it's going to take 20 years to build that rail line. If we spend $20 million a year, it's going to take five years. So to the extent that we can get a tax saving in the years when we're trying to expand our networks, it means that we can do it a lot more quickly. And because of the deferral aspect, we'll pay more tax when we don't have the deduction later on.
