I don't have any inside information on why it was cancelled. All I would say is that this program was working. We are aware of the fact that the new government is developing a new “clean air act”—or that's the name it's been tagged with—and we think this program is one that deserves reinstatement.
As part of the issue, one might ask why the industry doesn't invest in these things anyway. In most cases we would agree with that. But what we found with the auxiliary power units is that there's a heck of a cost associated with maintaining them. When you get that sort of message out to the industry, people are loathe to make an investment. So it requires, we believe, an incentive at this point to give people some comfort that they're not going to be absorbing a huge cost as a result of doing this.
