So Mike, I'll start with this, it's Kent, and then Tom will add some color. So Greif was a 14 cent earnings contribution that exceeded expectations, the headline number by, call it nine or 10 cents. Four cents of that was the depreciation benefit that we called out in the earnings release, okay? So if you're looking sort of apples to apples, five cents from expectations, that was driven by largely higher volumes than we expected and very good operational performance. But also we're running Greif now as a much more integrated system. It's much less separate from PCA legacy than when we made the acquisition, obviously by design. So there's some puts and takes. We're moving business between trying to get efficiencies maximized, and Tom can comment on this a little bit further.
