The only thing I would add, and it's a follow-up to Mr. Cullen's comments, is in terms of the alternative materials question, absolutely those products exist. Our industry innovates new materials for new applications, but it's very focused on the functionality. No regulatory agency has indicated or enacted guidance that has forced us to move away from DEHP PVC, and as health care manufacturers of products in that setting, we have a very vested interest, unlike the tobacco industry, in ensuring the health of our patients.
So those alternative materials exist, alternative products. The reason is that's what we do. We evolve materials.
