My question is to the Treasurer. I refer to the Treasurer's previous answer and I also refer to Morgan Stanley's note, issued today, which indicates the bank tax will raise $1 billion in 2017-18. Given the government has gone from claiming that it will raise $1.6 billion—yesterday by the Prime Minister—to $1.2 billion today by the Treasurer, what will be the shortfall in the bank tax over the forward estimates?
