We've experienced some difficulties moving into some new countries. As I said earlier, we're operating in 29 countries today. What we typically find is that they're not as mature, so their tax rules differ for us. That usually doesn't pose so much challenge on the investment front, but it certainly does when we want to change our footprint.
It's something that gets strong consideration, but typically we're a follower. We're not typically first there. Our customers are usually forging a path, and then we're coming later, so a lot of those things are established and there's some ability to leverage from whoever is there first.
Similarly, we operate six different business units, and in the past we've had one or another enter into a country, and then we're able, as soon as we get some feet on the ground, to leverage that around our business and share the best practice.
Developing markets are always very challenging, and it requires a lot of resources to understand the new systems and their complexities. When they're not as mature, the timelines to accomplish what you want get extended, and for us that's typically not acceptable. We're accountable to our customers to meet their timelines and deadlines. That's where we face a lot of challenge.
