Thank you for that. It helps to understand what's driving some of the expenditures.
I want to talk about accommodation and real property services. In the main estimates, you have net expenditures of $1.978 billion, and I see that planned spending in the RPP is $2.117 billion. There's a delta of about $140 million. Could you explain the difference between what's in the main estimates currently and what's in the planned spending for 2013-14?
