Okay.
Now in terms of the cost of the transit pass credit--I'm just trying to understand--there are two components. There's a numerator, which is the total money spent on the tax credit by the government, and the denominator is the number of tonnes reduced because of it.
Did I understand correctly that it will take until 2011 to know the value of the tax expenditure to the government? This is another naive question, Commissioner, but it seems that the revenue department would just have to press a button and figure out how many people claimed a transit tax credit. Why is it going to take until 2011? Did they give reasons for this? If so, are you satisfied with the reasons?
