One of the improvements that has taken place is in the 900-series numbers. They now have an expiry date. From my understanding, it is an improvement, but let's say a card expires immediately after the biannual review that's done by the department. The department reviews these cards, as I understand it—and I believe it was Ms. Cheng who had previously noted this—once every two years. Is that when they review the files on those?
