My presumption is that along with all the other revenue sources of the government, there would be a reckoning of what the pattern of that is over the fiscal year. If there were to be a shortfall on the $4.3 billion, then it would factor into the total revenue picture of the government and a calculation would be made at that point as to whether the government was in surplus or deficit.
