There already were a couple of questions on the issue of confidentiality. I guess maybe our department people can respond on this as well. But apparently mask names may be used to hide some of that confidential information regarding a substance, “Where the publication...of the explicit chemical or biological name of a substance would result in the release of confidential business information”. So I'm curious. I don't know what the sense of the industry members is in terms of that particular possibility, and whether they get faced with this sometimes. In particular, how often have those mask-name regulations been used, and for what types of compounds?
Shannon, do you want to start?
