 Beth, you point out a couple of companies, a few companies where this has happened recently. Freeport, McMoran, DuPont, Newell Brands have had this phenomenon happen there. We've seen CFOs elevated. Can you give us a sense of how that's working out? I mean, is it too early to tell? This is over the period of the last, what, year and a half. But any sense that you have of how effectively that's working at those companies and sort of maybe what those leaders have brought to the executive ranks there?
