That's an interesting question.
I mentioned labour market availability to begin with, and certainly one benchmark that we look at is labour market availability. So when we look at our own workforce or consider issues you have to be realistic about the starting point and about the realities of the labour markets that you're dealing with. Certainly, as I said, there are long-standing differences in the participation of men and women in natural resource sectors.
I think from an analytical point of view those are the facts, and we look to improve the gender equity as a matter of public policy, and in that sense it's a good thing to have greater parity.
