I have one final question, and this is for Ms. Noble.
When we look at the CDC, as you mentioned, there were two points. One was where there was investing in a “fund of funds” model, where the rate of return was very high, and the focus changed and the rate dropped very low. I think your goal generally is around 7% to 8% in terms of what investment return you're looking for. Am I correct?
I'm basically asking whether you have a defined rate of return, some ballpark figure you look at. It won't always be accurate but, generally speaking, do you look at a ballpark figure? That's just to give us an idea, when we're investing in certain places, what numbers we should be looking at.
