 Some of this is in our standard setting activity where the private sector attends and provides their expertise in the recommendations that get provided to the membership. It's the members who ultimately endorse all of our standards, but they don't really have a standard to endorse without the expertise of the rest of the private sector. Most of our members are airlines in the private sector. The other way that we do this is we have conferences and events where we get the wide views of absolutely everybody and that tends to shape priorities and strategies moving forwards as well as specific activities and action plans. So we work in a number of different ways with the private sector in order to capture as much information as we possibly can and produce the best output for everyone. What the UPU can learn from that is that it can be difficult to balance the fact that members in our case make the core decision, the ultimate decision, and yet the rest of the public sector or the rest of the industry actually provides all of their input, expertise and time. So there's a balance to be struck there in what's given back to them in terms of what value they actually get from their efforts involved in this.
