 All right. Now, when you're doing state and local contracts, the majority of time they're tax exempt. However, in some instances, and Maria will tell you this, we found out that they cannot be tax exempt. So we've had projects where the government, even though the government may be tax exempt, the particular contractor or subcontractor was not tax exempt. And so if you estimated that job or you bid that job without implying the taxes because you figure it was a state, local, or a federal project and you can't get a tax exemption status, you have to eat that. So that's the second thing I want you to look out for.
