Certainly not in the sense of tax shelters. If you're looking at the cost of the enhanced flow-through share program--and Tony, you might have more information on this--the actual cost of those programs has been quite minimal in terms of tax revenues foregone by the federal government--maybe $40 million to $60 million at best. But I'm not in that particular end of the business, so maybe Tony can bring greater clarity to it.
Is that the tax shelter you're talking about? It's not a tax shelter; it's an incentive to encourage investment in a high-risk area. Since those companies have no taxable income because they are not producing companies, the investor gets the flow-through to other income sources.
