Yes. The government has for a number of years decided to put an adjustment for risk, a provision in the fiscal framework of $3 billion per year to hedge against unexpected economic shocks. Effectively in 2012-13, as I was mentioning before, nominal GDP has been reduced significantly through the year because of global development and fairly weak commodity prices and weak domestic prices.
What this paragraph is saying is that in principle our revenue is down by $3 billion. If the shock is within this $3 billion, our revenue will be in line with what we expected. In this case the fall in GDP was important enough to go beyond the $3 billion, which forced us to reduce our forecast for revenues. I guess in itself it speaks to the fact that the $3 billion in some years is not enough to cover the potential high risk that we face.
