SURFACE TRANSPORTATION BOARD
Docket No. EP 689 (Sub-No. 1)
SIMPLIFIED STANDARDS FOR RAIL RATE CASES—
2008 RSAM and R/VC>180 CALCULATIONS
Decided: July 23, 2010
In this decision, the Board is publishing the most recent RSAM and R/VC>180 ratios for the Class I carriers (for the years 2005-2008), as well as their 4-year averages.
Under 49 U.S.C. § 10701(d)(3), the Board is directed to “establish a simplified and expedited method for determining the reasonableness of challenged rail rates in those cases in which a full stand-alone cost presentation is too costly, given the value of the case.” In Simplified Standards for Rail Rate Cases, EP 646 (Sub-No. 1) (STB served Sept. 5, 2007), the Board modified and clarified its guidelines for such cases by establishing a Simplified Stand-Alone Cost test for medium-sized cases, clarifying its Three Benchmark approach for the smallest disputes, and establishing eligibility thresholds for each type of case.
The Three Benchmark
approach compares a challenged rate to three measures of the defendant’s
revenues and variable costs. RSAM measures the average markup that the railroad would need to charge all of its
“potentially captive” traffic in order for the railroad to earn adequate
revenues as measured by the Board under 49 U.S.C. § 10704(a)(2). Potentially captive traffic is defined as all
traffic priced at or above the 180% R/VC level – which is the statutory floor
for regulatory rail rate intervention. See
49 U.S.C. § 10707(d);
In Simplified Standards for Rail Rate Cases—Taxes in Revenue Shortfall Allocation Method, EP 646 (Sub-No. 2) (STB served Nov. 21, 2008), the Board found a material error in its RSAM formula. The revenue shortfall (or overage) used in the RSAM formula was stated on an after-tax basis, whereas the other elements of the RSAM formula were stated on a pre-tax basis. The Board concluded that use of the statutory federal tax rate, combined with a railroad-specific state tax rate, should be used to convert the shortfall (or overage) to a pre-tax basis because it best approximates the marginal taxes the carrier would pay on incremental revenue. In Simplified Standards for Rail Rate Cases—Taxes in Revenue Shortfall Allocation Method, EP 646 (Sub-No. 2) (STB served Jan. 22, 2010), the Board adopted railroad-specific average 2008 state tax rates for each Class I railroad for use in the RSAM calculation.
benchmark is called R/VC>180.
This benchmark measures the average markup actually
applied by the defendant railroad on its potentially captive traffic. Both RSAM and R/VC>180 are
measured as 4-year rolling averages. The
ratio of RSAM to R/VC>180 reflects how far a particular carrier
is over or under its revenue adequacy target.
The R/VC>180 benchmark is calculated from the Board’s
confidential waybill sample as the total revenue earned by the carrier on
potentially captive traffic divided by the total variable costs of the railroad
to handle that traffic. Simplified
Standards for Rail Rate Cases, EP 646 (Sub-No. 1), slip op. at 20 (STB
served Sept. 5, 2007). The RSAM benchmark is calculated by adding the
carrier’s revenue shortfall (or subtracting the overage) shown in our annual
revenue adequacy determination to the numerator of the R/VC>180
The third benchmark is called R/VCCOMP. This benchmark is used to compare the markup being paid by the challenged traffic to the average markup assessed on other potentially captive traffic involving the same or a similar commodity moving similar distances.
The Board publishes tables each year showing the most recent RSAM and R/VC>180 ratios for each Class I railroad, as well as their 4-year averages. The R/VCCOMP ratio for appropriate comparison traffic is to be computed after a shipper files a rate complaint, using traffic data from the rail industry Waybill Sample, and applying the Board’s Uniform Rail Costing System (URCS).
The attached tables contain the most recent RSAM and R/VC>180 ratios. Tables I and II represent percentages for the most recent 4-year period 2005 to 2008 for all Class I carriers.

 This Board’s original small rate case guidelines contained in Rate Guidelines—Non-Coal Proceedings, EP 347 (Sub-No. 2) established an earlier version of the Three Benchmark approach. The Revenue Shortfall Allocation Method (RSAM) and Revenue to Variable Cost (R/VC>180) calculations were previously published under that docket.
