The following table shows the average shipments on the refined products pipelines in each of the years
presented. Average shipments represent the average revenue-generating pipeline throughput:
Year Ended
December 31,
2012 2011 2010
Pipeline throughput (thousands of bpd)(1)(2) ...................... 582 522 468
(1) Excludes amounts attributable to equity ownership interests in corporate joint ventures which are not
consolidated.
(2) In May 2011, we acquired a controlling financial interest in Inland and we accounted for the entity as a
consolidated subsidiary from the date of acquisition. Average volumes for the year ended December 31,
2011 of 88 thousand bpd have been included in the consolidated total. From the date of acquisition, this
pipeline had actual throughput of 140 thousand bpd for the year ended December 31, 2011.
The mix of refined products delivered varies seasonally, with gasoline demand peaking during the summer
months, and demand for heating oil and other distillate fuels peaking in the winter. In addition, weather
conditions in the areas served by the Refined Products Pipelines affect both the demand for, and the mix of, the
refined products delivered through the Refined Products Pipelines, although historically any overall impact on
the total volume shipped has been short term.
