I'll speak to that in a more general answer. I can't comment on those particular aspects.
The way we ensure integrity in the procurement process is very much around using process. The changes that we've put into the procurement system over the last three or four years have been about openness and transparency. The idea is to have independent third parties to document our governance decisions so they're publicly visible; to bring in a stated process that we follow with a timeline that is not compressed—in other words to have the adequate period of time for people to provide input; and to engage industry to have the procurement strategy shaped by industry, as opposed to our driving the procurement strategy.
That's a fair change. What it does is slow down the process, but it gives you more certainty that the industry recognizes that the procurement strategy is one into which they have provided input. With the use of the independent third parties that we bring in, it gives that assessment and that assurance.
