There's been no specific analysis with respect to that. At the time this was originally introduced, other jurisdictions had the same type of incentive for their businesses. Over time, those incentives, to the extent we can track them, seemed to have gone away in other countries as well. For example, when this measure was first introduced, the U.K. had a similar measure. Over the years, that measure has been pared back in the U.K. to the point where it now just applies with respect to seamen.
