1. A. Definitions.

   1. 1. "Average market value per rail car" means the fleet rail car market value divided by the number of rail cars in the fleet.

   2. 2. "Fleet rail car market value" means the sum of:

      1. (2) multiplied by the appropriate percent good factors contained in Class 10 of R884-24P- 33, Personal Property Valuation Guides and Schedules; and

         b) the sum of betterments by year.

      2. (1) Except as provided in A.2.b)(2), the sum of betterments by year shall be depreciated on a 14-year straight line method.
      3. (2) Notwithstanding the provisions of A.2.b)(1), betterments shall have a residual value of two percent.

      a)(1) the yearly acquisition costs of the fleet's rail cars;

   3. 3. "In-service rail cars" means the number of rail cars in the fleet, adjusted for out-of- service rail cars.

   4. 4. a) "Out-of-service rail cars" means rail cars:

      1. (1) out-of-service for a period of more than ten consecutive hours; or

      2. (2) in storage.

         b) Rail cars cease to be out-of-service once repaired or removed from storage.

         c) Out-of-service rail cars do not include rail cars idled for less than ten consecutive hours due to light repairs or routine maintenance.

   5. 5. "System car miles" means both loaded and empty miles accumulated in the U.S., Canada, and Mexico during the prior calendar year by all rail cars in the fleet.
   6. 6. "Utah car miles" mean both loaded and empty miles accumulated within Utah during the prior calendar year by all rail cars in the fleet.
   7. 7. "Utah percent of system factor" means the Utah car miles divided by the system car miles.
2. B. The provisions of this rule apply only to private rail car companies.
3. C. To receive an adjustment for out-of-service rail cars, the rail car company must report the number of out-of-service days to the commission for each of the company's rail car fleets.

4. D. The out-of-service adjustment is calculated as follows.

   1. 1. Divide the out-of-service days by 365 to obtain the out-of-service rail car equivalent.
   2. 2. Subtract the out-of-service rail car equivalent calculated in D.1. from the number of rail cars in the fleet.
5. E. The taxable value for each rail car fleet apportioned to Utah, for which the Utah percent of system factor is more than 50 percent, shall be determined by multiplying the Utah percent of system factor by the fleet rail car market value.

6. F. The taxable value for each rail car company apportioned to Utah, for which the Utah percent of system factor is less than or equal to 50 percent, shall be determined in the following manner.

   1. 1. Calculate the number of fleet rail cars allocated to Utah under the Utah percent of system factor. The steps for this calculation are as follows.

      a) Multiply the Utah percent of system factor by the in-service rail cars in the fleet.

      b) Multiply the product obtained in F.1.a) by 50 percent.

   2. 2. Calculate the number of fleet rail cars allocated to Utah under the time speed factor. The steps for this calculation are as follows.

      a) Divide the fleet's Utah car miles by the average rail car miles traveled in Utah per year. The Commission has determined that the average rail car miles traveled in Utah per year shall equal 200,000 miles.

      b) Multiply the quotient obtained in F.2.a) by the percent of in-service rail cars in the fleet.

      c) Multiply the product obtained in F.2.b) by 50 percent.

   3. 3. Add the number of fleet rail cars allocated to Utah under the Utah percent of system factor, calculated in F.1.b), and the number of fleet rail cars allocated to Utah under the time speed factor, calculated in F.2.c), and multiply that sum by the average market value per rail car.
