Quarterly RCAF Association of American Railroads
Introduction

On January 2, 1985, the Interstate Commerce Commission (ICC) [now the Surface Transportation 

Board (STB)] adopted the All-Inclusive Index of Railroad Costs as the basis for the Rail Cost 

Adjustment Factor (RCAF). The quarterly projection of railroad costs, as documented herein, employ

the All-Inclusive Index as required by the regulations. Also presented in this submission is the RCAF,

both Adjusted and Unadjusted, as required by the ICC in its decision in Ex Parte No. 290 (Sub-No. 4),

Rail Cost Recovery Procedures - Productivity Adjustment, served March 24, 1989. In addition, the

AAR has included (but does not endorse) the RCAF-5, which was instituted by an STB decision

served October 3, 1996 in Ex Parte No. 290 (Sub-No. 7), Productivity Adjustment - Implementation.

This quarter's projection of railroad costs is for the third quarter 2011.

2008 2009

 Labor 30.2 % 34.7 %

 Fuel 25.2 14.9

 Materials & Supplies 5.1 5.1

 Equipment Rents 6.3 7.1

 Depreciation 10.4 13.9

 Interest 2.3 3.0

 Other 20.5 21.3

In the Ex Parte No. 290 (Sub-No. 2) final rules, issued in April 1981, the Interstate Commerce 

Commission mandated that the weights of each major cost component be updated annually. These 

"external" weights are calculated using data from Schedules 410 and 210 of the R-1 annual report 

filed with the Surface Transportation Board by the Class I railroads. The weights are typically 

updated with the fourth quarter projection.

Reweighting of the index is accomplished by calculating both the current quarter (normally the 

fourth) and prior (normally the third) quarter indexes with the new weights. The relative change 

between the two quarters is then multiplied times the prior quarter (usually the third) linked index. 

Use of this method ensures that the weight change, by itself, does not cause a change in the level of 

the All-Inclusive Index.

Internal weights in the labor and equipment rents components are updated at the same time as the 

external weights. When these weights are changed, they are also linked using the procedure 

described above in order to eliminate the effect of the change in weighting.

The 2009 (current) and 2008 (previous) weights are shown below. The previous (2008) weights were 

used for the fourth quarter of 2009 through the third quarter of 2010. Beginning with the fourth 

quarter of 2010, the 2009 weights are used. The year 2009 was different from recent years. Instead 

of increases in the expenses used for the calculation of weights, declining demand for freight service 

caused the variable portion of expenses to decrease. Fuel is probably the most variable expense 

category, and fuel expenses dropped even more because of a lower cost per gallon and improving 

efficiency for locomotives. Not surprisingly, Fuel's weight decreased from 25.2 percent to 14.9 

percent. Labor expenses decreased, but did not decrease as much as many of the other categories. 

Thus, Labor's weight increased from 30.2 percent to 34.7 percent. Depreciation and Interest expense 

have little or no variability, and those expenses actually increased. Weights for those two categories 

increased. Changes for the remaining categories were less than one percentage point.

To calculate the 1980 = 100 Linked Index:

Index80 = (Current Index / Previous Index) * the Previous Quarter Linked Index

 = (297.5 / 290.1) x 284.4

= 291.7

To calculate the 4Q07 = 100 index:

Index4Q07 = (Current Linked Index / 4Q07 Linking Factor) * 100

= 291.7 divided by 245.9 times 100

= 118.6

Indexes based on other periods: 4Q02 based index = 291.7 / 192.1 x 100 = 151.8

4Q97 based index = 291.7 / 173.2 x 100 = 168.4

4Q92 based index = 291.7 / 156.9 x 100 = 185.9

4Q87 based index = 291.7 / 132.2 x 100 = 220.7

Forecast vs. Actual All-Inclusive Index

First Quarter 2011

Because of data availability, the forecast error adjustment has a two-quarter lag from each filing.

As shown below, the first quarter actual index of 112.8 is 2.0 index points above the forecast

value of 110.8. Therefore, the forecast error adjustment for third quarter 2011 is 2.0 index points.

Q1 2012 2.2724 2.3978

On February 7, 2011, the Surface Transportation Board (STB) served a decision in Ex Parte 290 (SubNo. 4) which added the year 2009 to the Productivity Adjustment Factor (PAF) and removed the year 

2004. This creates a geometric average annual productivity change, for the five-year period 2005 

through 2009, of 1.4 percent per year. The components of this average annual value are shown on the 

following table in ratio format – therefore, 1.014 is the same as an increase of 1.4 percent. 

Productivity changes are calculated by multiplying each of the five productivity changes together and 

taking the result to the one-fifth power. The quarter productivity adjustment factors (PAF) are 

calculated by increasing the previous quarter's PAF by quarterly versions of the annual rate, which are 

the fourth root of the geometric average annual growth rate. The difference between the PAF and the 

PAF-5 is the timing of the five-year productivity trend.

Labor

Third Quarter 2011

The third quarter 2011 Labor Index is forecast to increase 0.7 percent. Three items caused much of 

the increase: cost-of-living allowance increases for three national unions; cost-of-living allowance 

increases for numerous independent unions; and much higher annual profit sharing payments for one 

railroad.

Wage Rate Index

The Wage Rate Index portion of the Labor Index increased 0.8 percent from the previous quarter. 

Cost of living allowances and profit sharing caused the increase.

Wage Increases: There are only three national labor agreements in effect that have any type of wage 

increase scheduled for the third quarter, and those three unions will receive a cost-of-living 

allowance increase of 28 cents effective July 1. Numerous independent agreements also have a 

similar cost-of-livng allowance increase. One independent labor agreement has a 5 percent general 

wage increase scheduled for July 1.

Lump Sums: The third quarter lump sum rate increased 0.3 cents. This increase was caused by 

independent bonus payments paid by two railroads to qualifying employees of unions that signed 

new labor agreements between 2005 and 2010 – all of these agreements delayed the bonus payment 

until July 1, 2011. An additional independent bonus was paid by one railroad to selected employees 

of one union that signed a new labor agreement, and this bonus varied depending upon employee 

service years.

Back Pay: The third quarter back pay rate increased 0.1 cents because of a newly-received 

independent labor agreement that included back pay as part of the agreement.

Other: In wages, "Other" contains the amortization of incentive compensation payments that a large 

railroad makes each year to its dispatchers, yardmasters, and engineers. Last year's payment has now 

been completely amortized and removed from the labor rate. This year's payment, which is based on 

profits in 2010, is much higher than the previous year, causing the hourly rate to more-than double.

Supplements Index 

The Supplements Index increased 0.5 percent from the previous quarter. Almost all of the increase 

was caused by a railroad's independent employee stock plan contribution to employees of one of the 

largest unions.

Health & Welfare: The Health & Welfare rate was unchanged. Changes caused by the addition of 

one labor agreement to the index were too small to have an impact on this rate.

Association of American Railroads
Quarterly Rail Cost Adjustment Factor Appendix A Page 2 of 3

Labor

Third Quarter 2011

Railroad Retirement: The Railroad Retirement rate increased 0.6 percent, as taxable income was 

up slightly.

Unemployment Insurance: The unemployment insurance hourly rate was unchanged.

Other: The "Other" category is a reflection of all other fringe benefits, and currently contain known 

employer contributions to employee 401(k) accounts and employer contributions to employee stock 

plans that are recorded as fringe benefits. The hourly rate increased 4.4 cents, caused by one 

company's annual match and another company's extra bonus match included in the startup of a new 

plan.

Labor Index Calculation

As shown in Table A-1 on the next page, the 0.8 percent increase in the Wage Index and the 0.5

percent increase in the Supplements Index had a combined effect of a 0.7 percent increase in the 

Labor Index. The linked third quarter 2011 index is 382.1.

* Diesel fuel used by locomotives is made from refined crude oil, and therefore usually has some price correlation.

** Heating oil and locomotive diesel fuel are part of a group of closely related products, commonly labeled as distillates, that differ mostly by their 

 sulfur content. Because of these similarities, these fuels are produced together and have similar pricing trends.

The forecast for fuel is based on: (1) a survey of railroad fuel purchasing officers concerning current 

price and volume levels, (2) expectations of railroad purchasing officers based on their own forecast 

models and discussions with their major suppliers, and (3) a consensus of petroleum industry experts 

and general business publications.

Crude oil futures prices were above $100 per barrel for the month of April, but fell below $100 in 

May.* Inventories were above the average range during that period. In early June, disappointing news 

relating to the U.S. economy contributed more downward pressure on oil prices.

Locomotive diesel fuel prices have trended upward (with a few "dips") since a March 2009 "trough". 

April 2011 is the latest month available for locomotive diesel fuel prices, but data for diesel fuel, 

heating oil and other distillates – which have a reasonable degree of correlation with locomotive diesel 

fuel – are available for later periods**. Data provided by the U.S. Energy Information Administration 

show lower prices in recent weeks and inventories at the high-end of the average range. 

Railroads believe locomotive diesel fuel prices for July 2011 (Q3) will be 3.9 percent lower than the 

second quarter's (represented by April in the Fuel Index) average price actually paid. However, 

because the second quarter forecast was much too low, the third quarter 2011 forecast is 6.5 percent 

higher than the second quarter forecast.

The third quarter 2011 Materials & Supplies Index increased 3.5 percent from its second quarter 

value. The increase was caused by higher prices paid for two of the three major materials categories: 

Metals and Miscellaneous products. The index is still below its all-time high of 258.8 set for the first 

quarter of 2009.

Weighted Average 198.4 204.0 2.8

Weighted Average (Linked) 203.1 208.8 2.8

The Equipment Rents Index consists of two components – car hire and lease rentals. The 

methodology used to create these two components and the final Equipment Rents Index are explained 

below.

Car Hire

The car hire component is indexed using data from the Car Hire Accounting Rate Master (CHARM) 

file. Car hire rates for the forecast quarter are estimated based on data for the most recent month 

available. For the first quarter, December 1 of the previous year is used. For the second, third and 

fourth quarters; March 1, June 1, and September 1 are used, respectively. Using data retrieved from 

the latest CHARM file, an average rate per car is developed. Next, those average rates are grouped 

into car type categories to create an overall summary of car hire rates. The summary rates are then 

compared from quarter to quarter to determine the Car Hire Index.

Lease Rentals

The lease rentals portion of the Equipment Rents Index uses the Producer Price Index for Industrial 

Commodities less Fuel and Related Products and Power (PPI-LF). The Commission adopted this 

surrogate in its decision served March 13, 1987. The AAR uses six years of historical data to derive 

its forecast for the PPI-LF. The forecast is used not only for lease rentals, but also for the "Other" 

component of the All-Inclusive Index. Appendix G discusses the forecast in more detail.

Equipment Rents Index Calculation

The table below calculates the Equipment Rents Index, which increased 2.8 percent. The third quarter 

Car Hire portion of the Index increased 0.2 percent, caused by small increases (since March) for 

privately-owned cars. A 4.4 percent increase for the PPI-LF (see Appendix G) used as a proxy for 

Lease Rentals, combined with the 0.2 percent increase for Car Hire, caused the Equipment Rents 

Index to increase 2.8 percent.

Change from actual first month of previous quarter 0.6%

Change from same quarter of prior year (actual) 1.0%

The Producer Price Index for Railroad Equipment (PPI-RE) is used to index depreciation expense. 

The PPI-RE is forecast using an ARIMA (Auto-Regressive Integrated Moving Average) process where 

a statistical package picks the model that best fits the historical data set (see next page), and that model 

is then used for the forecast. The historical data set contains 6 years of monthly data (a sample size of 

72), where the most recent available data point is the first month of the quarter prior to the forecast 

quarter. For a first quarter forecast, the most recent month of data available would be for October of 

the prior year. For a second quarter forecast, January would normally be the most recent period 

available. April and July would be the most recent months available for third and fourth quarter 

forecasts, respectively. The output from the forecast model is shown on page 2 of this appendix on a 

1982=100 basis. The figure forecast by the model reflects monthly PPI-RE figures that changed by 

only small amounts during 2010, but had some bigger increases in 2011.

The Interstate Commerce Commission, in its decision served February 28, 1989, revised the AllInclusive Index methodology to include a specific interest component, which is to track changes in 

the average interest rate from year to year. The interest rate is essentially the embedded cost of 

debt, i.e., total interest expense divided by average total long term debt. The interest rate is 

calculated for the most recent year and used until the next year's figures are available. Typically in 

the fourth quarter filing, the interest rate is updated to the new level. The source for interest expense 

is Schedule 210, column b, from the R-1 annual report. The lines used from current R-1 annual 

reports are listed below. The source for average total debt is Schedule 200 from the R-1 annual 

report. The sums of data from columns b and c (ending and beginning balances) are combined and 

divided by 2 to compute an average balance. The line numbers are listed below. Beginning with 

fourth quarter 2010, the Interest Index is based on data for 2009.

The Producer Price Index for Industrial Commodities less Fuels and Related Products and Power (PPILF) is used to index purchased services, casualties and insurance, loss and damage, taxes (other than 

income and payroll), general and administrative expenses, and lease rentals. These expenses, when 

grouped together, are usually called "Other" expenses.

Like the PPI-RE, the PPI-LF is forecast using an ARIMA process on 6 years of monthly data (a sample 

size of 72) with the most recent available monthly data being the first month of the quarter prior to the 

forecast quarter. For a first quarter forecast, the most recent month of data available would be for 

October of the prior year. For a second quarter forecast, January would normally be the most recent 

month available. April and July would be the most recent months available for third and fourth quarter 

forecasts respectively. The output from the forecast model is shown on page 2 of this appendix for 

1982=100. The figure forecast by the model for the third quarter reflects monthly PPI-LF figures that 

are increasing at higher rates in 2011. Preliminary indications are (see chart) that recent forecasts may 

have been slightly low, which would exacerbate the increase from the prior quarter forecast.
