As I say, I think the key thing to look at in these measures is the fact that with the grandfathering and the transition, they will take place slowly over time.
The idea is to provide greater neutrality in the corporate tax system and to have investment decisions made in the mining industry undertaken based on economic fundamentals.
As you are also aware, certainly the government has put in place a number of measures on the other side to facilitate mining in this country, things such as the regulatory review that was announced in the previous budget.
