What we looked at was specifically construction equipment and the differences between the two countries. The depreciation rate in the United States is far more aggressive. Now, the Department of Finance will tell you that this is because corporate taxes in the United States are higher. I'm not advocating that we touch our corporate taxes—I think our members are quite happy with where they are—but one of the things that aggressive depreciation allows you to do is to invest in equipment more quickly.
That's something that frankly we don't see here. Our depreciation rates are tied to the useful service life of the asset rather than to the productive life of the asset. The productive life of most construction equipment is about four to six years, only because these engines are constantly running. Once they've reached that limit, you sometimes will find other uses for them—you don't necessarily retire them altogether—but our perspective is that we should be frankly encouraging companies to invest in the newest equipment, particularly tier 4 engines, which are a dramatic improvement over the tier 3s when it comes to pollution control equipment.
Right now, given the change in our currency, we have a lot of equipment sitting in dealers' showrooms that just isn't going to be moving anytime soon. Aggressive depreciation I think would encourage businesses to begin investing. Those are investments that stay within the company, so those are investments in Canada.
