Sure. I'll give you a comparison of where we are with respect to the U.S. Under the current system in the United States, which is more of a direct depreciation, a typical piece of equipment is written off within six years. Under the current system in Canada it takes 11 years, and you're still not really there. The useful life of a lot of this equipment is turning over in a three- to five-year cycle.
