Thank you. The report is based on a certain assumption of a mix of the assets between equities, fixed income, or real assets, as they're called.
With regard to operating expenses—and I'm going to put that not just under operating expenses but the whole umbrella—my personal view of CPPIB, even in working in the private sector side in dealing with the process, is that CPPIB is probably one of the best run—if not the best run—fund manager or asset manager in the world. It is a model, I believe, for dealing with retirement issues and beneficiaries, especially in light of the demographics that the western world is facing. When I say that, I say that here in Canada. for the first time ever, this year we have have more retirees than people under 15.
On the expense side, I'd like you to comment on this. The CPPIB has done a great job on operating expenses and maintaining that. On external management fees, can you provide some colour on the trend there and what is going on with external management fees? I see that in 2016 there was $1.3 billion in external management fees paid. Could you give some perspective on that, please?
