Absolutely. I'll try to do that in two stages.
The one point is asking about how long it takes to get U.S. customers. We have had a tremendous partnership with Dofasco, all three of our steel mills, but ArcelorMittal Dofasco has been a large part of our growth. As Sean mentioned, it is affecting our community. I'm one of his customers who is dealing with that. Since 2014 we have really grown to that number—as I said, it's 270% growth—and it only takes a couple of times when you are offside in a competitive nature or when you're quoting a job that you will start to lose your footprint in an area.
We are large suppliers to the RV industry. We heard someone speak about that today. That is a very thin-margin business. We have a great footprint there. We have invested in Janco Steel. We have put in four lasers in the last two and a half years. We have started doing a parts business. That is going to be lost because they will go elsewhere very quickly.
The uncertainty you speak about, Dean, is that if we knew the rules and if we knew the rules were going to last for the next year, we could maybe make a good business decision, but right now the last thing we want to do is lay off people. We went through the financial crisis of 2008-09 and we did not lay off any workers. We actually expanded in 2010. Our biggest growth has been from 2010 to now. It is tens of millions of dollars that we have invested back capitally into our company, and we don't know the rules any more.
I can tell you that when I say we will have to have a decision about laying people off, it is real. That is not just saying something to make a big statement. We're going to have to do that. We do not want to do that.
