So the labor market -- Matt, I think the -- we've been restructuring the whole Barrick Human Resource, so we had Graham. We want -- I've just finished a global engagement on all our operations with our executive teams looking at progressing our vision of much flatter structures, deeper reach into our organization, more accountability at levels, taking out management levels because -- and also, we have a very big commitment to education, both upskilling technical skills and educating right at the base from high school across the globe. And whilst there is a tightness in the supervision forma-based areas of Nevada, we've just -- so we replaced about 90% of the people we employed last year we've retained. So again, as we change the profile of our employment base, we're slightly higher on the turnover. But this year-to-date, we've replaced significantly more than what -- than the resignations or leaving. So I think for me, it's a challenge. But at the same time, it's a significant opportunity as we look to give people more accountability, pay people more, pay people differently and position, particularly in Nevada, for a more modern way of mining. And we've done an enormous amount of work in Latin America. Mark Hill and the team were much more aligned with my vision of how we employ and how we pay. Africa has done extremely well. And as I pointed out in my presentation, to we -- our succession efforts are really paying dividends. And you'll see as we progress and we've appointed senior executives, both through promotion or succession and from external sources. We've been able to do that without having to say, oh, so and so is retiring and we're waiting to fill that position. We've done it well within the time. We've got good transition plans to ensure that we have continuity in our operations. And again, our focus has been to beef up on our senior, what we call big mine general managers, some of the more important skills that that are under pressure, investing in those. And so, it is a point that we have to manage in the market. At the same time, as I said, it's an opportunity for us to redefine some of our management and leadership structures across the Group.
