Thank you.
On our exposures to a wide variety of different types of companies, you mentioned, for example, tobacco. As well, in the U.S. some detention centres are privately run. As part of our efforts to widely diversify the fund, not only geographically but by asset, some segments of our businesses, some of our investment strategies, efficiently apply indices, which means that, to gain added exposures, we might put part of the fund in something that would mirror, say, the SNP500. In doing so, we would then capture some of these types of assets you referred to.
What's come to the fore for us is that.... Individually, these are very tiny exposures for the CPP fund in the context of $400 billion-plus; some of them may be one or two million dollars, because they're spread out across about 4,000 holdings. Even though we've had a very robust due diligence process on the wide variety of risks that would come our way when we make a direct investment in a specific company—a much larger position—we found there could be some exaggerated risks even if it's a small holding.
So we've applied the learning from the processes we've had in looking at large positions. We found tools that are able to identify where there could be exaggerated sources of risk, whether they're controversy risks, social or governance risks, or environmental risks. When those are flagged to us, even though there could be thousands, we're able to narrow them down to a few, and then we're able to apply a more rigorous, detailed assessment. In some of those cases, it's turned out we were not comfortable with the wide range of risk, and the example you provided around detention centres would be one of those cases.
In a situation where we've looked at tobacco companies.... By virtue of our mandate, we don't have broad, sectoral, broad-brush exclusions, so it is not consistent with the CPPIB Act to say we will not invest in tobacco, full stop. Having said that, it does allow us to take an idiosyncratic view if a particular tobacco company is behaving in a certain way that increases, for example, its legal risks. Then we are given the opportunity to do a deeper dive, and there have been instances where we were not comfortable.
At the end of all this process, the one thing that stands consistent is being true to the legislative mandate of making sure that when we are taking a position for the long-term returns we are also equally looking at the long-term risks associated with them.
