Roughly, in 2017 we had about $20 million, give or take, of spend with diverse suppliers. I'm sorry, but I can't do the percentage off the top of my head.
We are again looking at future phases of how we're going to get reporting down through their own subcontractors to help inform us. We've learned through discussions with the supplier councils that this is often the way private organizations have started. They start at tier one and get the information from that, and then they start looking at how to get down to the tier two and tier three levels.
