There are a number of reasons that it took so long. We were getting investigation requests and, while working through that, realized that our processes could be better, so we made a commitment to streamline the process for investigation. Over the last few years, we've brought down the time it takes to carry out an investigation significantly, something in the order of 20% since 2014-15. We're now looking at undertaking some process, a re-engineering exercise, lean management, for example, to continue to do that. It's an ongoing process, but we're slowly working on it to reduce the amount of time that it takes.
