SIMEON BROWN (National—Pakuranga): Thank you, Madam Chair. I'd like to carry on from where my colleague Simon Watts was asking some questions before, which is around clause 4, regarding the replacement figure for the minimum family tax credit. Under this proposed piece of legislation, it proposes to replace the number "$30,576" with "$31,096", and he had a very good question, which was asking what advice or formulas had the officials used to come up with the figure $31,096. I didn't get an answer, Simon didn't get an answer, Chris didn't get an answer—none of us got an answer—and, Madam Chair, I don't think you got an answer, either. I think it would be helpful to the committee if the Minister could actually answer that question.
