Maybe I'll add a bit to that, because I think these contracts contain proprietary and commercially sensitive information for all companies. When we take a look at where we were when we originally signed those contracts and where we are today, it is easy to say that we are past the pandemic, but we're still managing. Even today, we are working with countries around the world for supply to vaccines. Those same sensitivities that existed two years ago are in play right now.
I would say that, in addition, there are things that are confidential to the country that we're working with, the other signatory on the agreement. There are things around the supply schedule, delivery and other supports that we're providing to that market.
