NOTE: The CFS totals in this table differ from the larger BTS totals specified in the text and in tables 1, 2, and 3 because they do not include additions to account for the out of scope missing pieces and some in-scope segments that were underrepresented in the CFS, such as waterborne and pipeline shipments.
