It's 5% for some companies and 30% for others, so what we use is a conservative estimate of 10%, but it varies.
I'll give you an example. Many of our people said that if it had not been for CPI and for the federal government work we've done in Russia.... Russia is our third largest market now. We used to have all kinds of problems. At one time, we had only one plant that was allowed to export to Russia. That was less than a year and a half ago. Now all our plants are approved again, so it varies. Use the figure of 10%, which is the conservative figure. But it varies from 5% to 30% for individual companies.
