I would be happy to take that.
There are two elements. The first was kind of re-documenting the expectation from our commercial system in terms of revenue increase, in terms of facilitating the passage of compliant goods, in terms of the acceptance of trade chain partners. It was to kind of reconfirm that we were looking at the right things to judge the success of this, and then to ensure that we were set up to monitor it on an ongoing basis.
There were a series of conversations in which we said, “Well, that's not something we just need one time. That's something that we should be looking at day in and day out after the next decade.” We decided to build that model ourselves. For validation of that model, our independent internal audit unit stepped up. They had some capacity and offered to lend the element of independence. I think we forwent the expertise of an outside vendor to build the in-house capacity so that we could stay focused on it on a more ongoing basis.
