B. Andrew Rose -Worthington Industries, Inc. -CFO andEVP Yes, that's probably a bridge too far for me to answerfrom... JohnCharlesTumazos-JohnTumazosVeryIndependentResearch,LLC-PresidentandCEO You're not worried about losing any customers because ofthat? B. Andrew Rose -Worthington Industries, Inc. -CFO andEVP Because of the discrepancy in steelprices? JohnCharlesTumazos-JohnTumazosVeryIndependentResearch,LLC-PresidentandCEO If the U.S. has a price premium,yes. B. Andrew Rose -Worthington Industries, Inc. -CFO andEVP I don't think in our Steel Processing business that's the case. I just think the supply chain benefits locally are much better. So anyway, I don'twant to go too far down the path, John, of talking general Worthingtonhere.
