This is a resource rent tax and it has two features which are not understood by those opposite, so I will just go through them. They are different from the PRRT. Those two features are transferability and refundability. The member has asked me a question about the modelling of the revenue that the Treasury has done and how much of that may take into account the tax credits that are given to companies for their investments. She has asked me about that and she knows very well that there is no way anybody could give an answer to that question—nobody could.
