I'd be happy to.
First of all, in terms of the economic contribution, there are just a couple of statistics that might be helpful. Indirect and direct employment from the oil and gas sector across the country is about half a million people, so there's a very significant contribution to jobs across Canada. The companies that comprise our industry are about 25% of the value of the TSX--again just another metric that would give you a sense of the economic contribution we make.
In terms of the tax treatment we're suggesting, what we're asking is that rather than a 30% declining balance--which is the normal tax treatment for development expenditures--for a time-constrained period those expenditures are allowed full deductibility. So it effectively changes the phasing of tax deductions for those particular expenditures.
Maybe I'll just ask Mr. Herring to say a few words in response to your question about employment and how our proposal would impact employment in the industry.
