It's pretty difficult to isolate certain factors. I appreciate the question, but I can say in general we have a very high naturalization rate. It's about 85%. So of those 15% who don't seek citizenship over a fairly long period of time, there are a number of reasons for that. Some of that has to do with dual citizens or the host country, people's own desires. There are a lot of factors.
But in terms of being able to analyze those who are afraid to take the test, I'm afraid I don't have much on that.
