It's a very good question.
First of all, when it was introduced in the legislation, there was no costing required because it was a legislative amendment, in 2014. When we went through the regulatory process, we were aligning with the U.S. under the regulatory co-operation council, which was very ambitious and effective, because we are harmonized, for almost all intents and purposes, on our safety data sheets with the U.S.
We moved away from the costing because there was already a regulation in place, so they could say that the regulation was neutral, under the one-for-one rule.
