The Valuation Act is a 1913 United States federal law that required the Interstate Commerce Commission (ICC) to assess the value of railroad property. This information would be used to set rates for the transport of freight.
The act was the brainchild of ICC commissioners Charles A. Prouty and Franklin K. Lane. Its objective was the setting of fair rates for freight shipments. It was a classic piece of Progressive Era legislation designed to find a scientific basis for setting tariffs (shipping charges) by determining the correct value of each railroad's real property and assets. Members of Congress assumed that with this information, the ICC would be able to set rates according to the principle of a reasonable rate of return on the real value of each railroad and the industry as a whole.
The law amended the Interstate Commerce Act of 1887 and required the ICC to organize a Bureau of Valuation in order to undertake the assessments. The ICC formulated a set of procedural and reporting standards for the valuation process, and then permitted the individual railroads to complete the valuation under the nominal supervision of an ICC administration. In 1914 Prouty resigned from his Commissioner post at the ICC to serve as the first Valuation Bureau Chairman.
Although the original intent of the Valuation Act was to prepare a one-time assessment of railroad assets, subsequent legislation had the effect of prolonging the process. The Esch-Cummins Act of 1920 expanded the ICC's rate-setting responsibilities, and the agency in turn required updated valuation data from the railroads. The enlarged process led to a major increase in ICC staff, and the valuations continued for almost 20 years.
Congress passed a minor amendment to the law in 1922.
The valuation process turned out to be of limited use in helping the ICC set rates fairly.
Except to take up incredible amounts of space on library shelves, the reports of the valuation agency never served any visible purpose.
