There were two methods. The main method was looking at the increase in demand after the first Frank ruling, if I'm not mistaken, at the trial that struck down the five-year rule. We then saw an increase for several months, during a number of months, when the five-year rule was removed, so some projections were made based on that.
We also know that in the United States, Americans abroad can vote without restrictions as to the years they've been away, so we looked at the proportion of Americans abroad who vote as compared to the proportions of Americans in the States who vote. You have to take into account that many Americans abroad are in the military, and that's a bit of a skewing of the numbers, so it's not an exact science.
Our projections of 30,000 remain. I would call that a class D estimate, in the sense that it's not an exact science, but we maintain our position on those numbers at this point in time.
