Usually there are a number of investigations going on at the same time and they take varying lengths of time to complete. What we found this past year was that as the year began we had quite a few investigations that had been going on for more than a year or two, so we were determined to get those ones closed down. We actually managed to close down five of them. Not all of them were carried over. I think that's approximately the numbers that we're having of investigations.
There's not a huge difference. The lowest number was in 2010-11 and there were 39 files opened. The highest was in 2012-13, which was 48. This year it's 45, so we're within the same ballpark generally. You have to distinguish the files opened and the files for which we actually initiated an examination. Of course, the 49 are all the files opened, which is why so many are closed, because we look into them and see whether there's any merit. Sometimes it's from getting a request, and sometimes it's something I've seen or that has come to my attention from the general public. We're very careful though that with any information that comes in we consider it carefully to determine whether indeed there is anything that should be investigated.
There are many more files that are opened and closed than there are examinations begun.
