That's a good question.
There is definitely less available information for those asset classes, but we do have a thorough understanding of how their returns should behave over time, and that's enabling us to basically formulate views on how they would be.... Real estate is an example. Although there is limited information for some asset classes, such as infrastructure, for real estate there is more information, and we're about to have a clear view of what the return will be with those asset classes.
