Yes, in the NAFTA context it's a very seamless border of developed mutually complementary product lines. Canadian producers don't offer the range of product offered by U.S. producers. Our customers know that they're going to need to access both of those commodities on either side of the border.
As an industry we have embraced NAFTA integration. A lot of our large producers, as I mentioned, have facilities in the United States and maintain significant employment in the United States.
To the raw materials question, yes, $1.5 billion U.S. in metallurgical coal, scrap steel, other metal components, and iron ore last year alone is a significant commodity buy, along with with all the employment and economic activity it supports, such as in the mining sector in the United States, including iron ore and coal, the raw materials, transportation, and significant shipping.
Beyond the $1.5 billion, tremendous spinoff benefits are associated with that activity.
