Rate of Return Comparison for Mr. O'Loughlin's Data Sets Rate of Return Basis Point Item 2009 2014 Differential [1] [2] [3] [4] Preliminary Data Set Middle 50% Mean [a] 9.4% 9.0% -38 Median [b] 9.7% 8.7% -24 Intermediate Data Set Middle 50% Mean [c] 9.7% 9.1% -56 Median [d] 9.6% 8.8% -10 Final Measurement Group Middle 50% Mean [e] 9.8% 9.0% -78 Median [f] 9.8% 8.7% -10 Sources: See Appendix SR-D. These measures of central tendency are calculated for the pipelines in my data sets used to calculate the average annual cost change. These calculations do not account for mergers and acquisitions. Any pipeline missing a rate of return in either 2009 or 2014 is excluded from the calculations in order to keep the calculations comparable.
