We have a complex network of KPIs that we use in conjunction with our airport security screening agreement with the screening contractors. Those are measured on a daily basis through CATSA personnel called performance officers who watch the screening officers perform their duties at airports all across the country every day. They never achieve perfection, so we're always trying to make it better. The answer is that it's not a one or a zero. It's not that they're not achieving their targets. It's just that we're always trying to encourage them to do better.
One of the ways we do that is built into the contracts, because we use third-party service providers. We build in financial incentives that incentivize these third-party service providers to improve their performance. What we do is adjust those KPIs and the associated financial incentives every year to encourage exactly what you've talked about, which is better performance.
