We don't put specific targets around countries. We don't have a specific target for the U.S. We don't have a specific target for the United Kingdom, Germany or France. We need to leave a certain level of flexibility. We have a number of investments in Australia, and we feel that we're comfortable with that exposure today. It doesn't mean that if a great opportunity came along we wouldn't look at it.
We don't have specific targets, but from a portfolio construction perspective, there would be a ceiling at some point—not an arbitrary one—where we would feel we'd be too concentrated in Canada. Because of what I've said about the other factors that affect the CPP, we would have to prudently ensure that we are always dealing with that concentration risk.
