 So we're up on the break, Andrew. When you come back, I'm going to ask you a little bit about the 4P tool and what that – you've touched on the evaluation of price reasonableness, but we'll get a little bit on that. Then I think we'll talk a little bit about compliance and contractor assessments to finish up the show. My guests today are Sean Nolte. He's a managing consultant and director of DC Operations and Training.
