The Railroad, along with its subsidiaries and rail affiliates, is our one reportable operating segment. Although we provide and analyze revenue by commodity group, we treat the financial results of the Railroad as one segment due to the integrated nature of our rail network. The following table provides freight revenue by commodity group:

Although our revenues are principally derived from customers domiciled in the U.S., the ultimate points of origination or destination for some products transported by us are outside the U.S. Each of our commodity groups includes revenue from shipments to and from Mexico. Included in the above table are revenues from our Mexico business which amounted to $599 million and $519 million, respectively for the three months ended June 30, 2014, and June 30, 2013 and $1,139 million and $1,024 million, respectively for the six months ended June 30, 2014, and June 30, 2013.
