It's not insignificant. I've spoken to our service deliverer, Kasar Canada, and they've indicated that costs can run to easily $50,000 for a trucking company to put a program in place. And then there are ongoing costs as well for audits, for example, and the cost of those audits would depend on the number of facilities you have that have to come under scrutiny.
But, again, in the scheme of things, compared to the other costs of running a trucking company, it tends to be small.
I'm not sure if John wants to comment on that.
