STB Ex Parte No. 290 (Sub-No. 4)
RAILROAD COST RECOVERY PROCEDURES—PRODUCTIVITY ADJUSTMENT
Decided: January 26, 2010
We propose to adopt 1.010 (1.0% per year) as the measure of average (geometric mean) change in railroad productivity for the 2004-2008 (5-year) averaging period. This value represents a 0.5% decline from the current measure of 1.5% that was developed for the 2003-2007 period.
Since 1989, the cost recovery procedures have required that the quarterly rail cost adjustment factor (RCAF) be adjusted for long-run changes in railroad productivity. The ICC Termination Act of 1995 continues this requirement. See 49 U.S.C. 10708. This long-run measure of productivity is computed using a 5-year moving geometric average.
Productivity change for the year 2008 is 0.997 based on changes in input and output levels from 2007, representing a decrease of 2.1% from the rate of productivity growth in 2007 relative to 2006 (1.018). Incorporating the 2008 value with the values for the 2004-2007 period produces a geometric average productivity growth of 1.010 for the 5-year period 2004-2008, or 1.0% per year. As the new geometric mean was computed by replacing the 2003 figure of 1.019 with the lower figure of 0.997 for 2008, there was a 0.5% decrease in the geometric mean from last year’s value. A detailed discussion of our calculations is contained in the Appendix to this decision.
Comments may be filed addressing any perceived data and computational errors in our calculation. Any party proposing a different estimate of productivity growth must, at the time it files comments, furnish the Board with one set of detailed workpapers and documentation underlying its calculations. The same information must be made available to other parties upon request.
This decision will not significantly affect the quality of the human environment or the conservation of energy resources.
It is ordered:
Comments are due by
February 22, 2010.
2. An original and 10 copies must be filed with:
395 E Street, S.W.
Comments must be
served on all parties appearing on the current service list.
4. Unless further order is issued postponing the effective date, this order becomes effective on March 1, 2010.

The following is a description of the methodology currently used to calculate the RCAF productivity adjustment. The annual rate of productivity change is calculated by dividing an output index by an input index.
The input index uses constant dollar-adjusted expenses. The inputs in this index—freight expenses, fixed charges and contingent interest—are stated on a constant dollar basis using the most recent year as the base, and updating the base by the Series RCR Index published by the Association of American Railroads. Freight expenses, fixed charges, and contingent interest were obtained from railroad Annual Report (Form R-1) data. The constant dollar adjustment factor for each of the 6 years was calculated by dividing the 2008 RCR index value (472.7) by the RCR index values for 2003 and each subsequent year through 2007, inclusive. Because 2008 is the last year in the trend, no constant dollar adjustment was needed for that year. The calculation of the input indices and values used are shown in Table A.
output index was developed from the costed waybill sample, a commonly used data
source. The costed waybill sample
excludes movements originating in
Using the costed waybill sample as a base, each movement is assigned to one of the 189 segments or categories used to develop the output index. Segmentation is based on three mileage blocks, seven car types, three weight brackets, and three shipment sizes. The output index is a composite of the year-to-year change in ton-miles for each of the 189 segments weighted by each segment’s base-year share of total revenues.
The change in productivity is calculated by dividing the output index by the input index. The multi-year average for the period 2004-2008 is calculated by taking a geometric mean, which was found to be 1.010 (1.0% per year). The input index, the output index, the annual productivity change, and the calculation of the 2004-2008 average are shown in Table B.

The 5-year (2004-2008) productivity trend calculated using a geometric average is 1.010, or 1.0% per year.
