Code of Federal Regulations Title 49. Transportation 49 CFR Pt. 225, App. B—PROCEDURE FOR DETERMINING REPORTING THRESHOLD

1. Wage data used in the calculation are collected from railroads by the Surface Transportation Board (STB) on Form A—STB Wage Statistics. Rail equipment data from the U.S. Department of Labor, Bureau of Labor Statistics (BLS), LABSTAT Series reports are used in the calculation. The equation used to adjust the reporting threshold has two components:  (a) The average hourly earnings of certain railroad maintenance employees as reported to the STB by the Class I railroads and Amtrak;  and (b) an overall rail equipment cost index determined by the BLS. The wage component is weighted by 40% and the equipment component by 60%.

2. For the wage component, the average of the data from Form A—STB Wage Statistics for Group No. 300 (Maintenance of Way and Structures) and Group No. 400 (Maintenance of Equipment and Stores) employees is used.

3. For the equipment component, LABSTAT Series Report, Producer Price Index (PPI) Series WPU 144 for Railroad Equipment is used.

4. In the month of October, second-quarter and first-quarter wage data for the current year, and fourth-quarter and third-quarter wage data for the previous year are obtained from the STB. For equipment costs, the corresponding BLS railroad equipment indices for the same time period as the STB wage data are obtained.

5. The wage data are reported in terms of dollars earned per hour, while the equipment cost data are indexed to a base year of 1982.

6. The procedure for adjusting the reporting threshold is shown in the formula below. The wage and equipment components appear as fractional changes relative to the prior year. After performing the calculation, the result is rounded to the nearest $100.

7. The weightings result from using STB wage data and BLS equipment cost data to produce a reasonable estimation of the reporting threshold that was calculated using the threshold formula in effect immediately before calendar year 2006, a formula that assumed damage repair costs, at levels at or near the threshold, were split approximately evenly between labor and materials.

8. Formula:

New Threshold = Prior Threshold x [1 + 0.4(Wnew—Wprior)/Wprior + 0.6(Enew–Eprior)/Eprior]

Where:

Wnew = New average hourly wage rate ($).

Wprior = Prior average hourly wage rate ($).

Enew = New equipment average PPI value.

Eprior = Prior equipment average PPI value.
