Section 791
Section 791.70
Investment-related Cost Study Components
a) Material. The material component of investment shall be based
on the most recent vendor prices, reflecting applicable discounts and all
applicable taxes, for the hardware and software resources required to provide
the service. The carrier shall provide a breakdown of the material involved in
providing the service.
b) Inventory and supply. The inventory and supply components
shall reflect the costs to the company of inventory, administration, storage
and delivery.
c) Labor investment. The labor investment component shall
consist of the labor required to install and put into service capital assets.
The labor investment component shall be divided into two components,
vendor-related and carrier-related labor investment. Vendor-related labor
investment shall include billed installation and engineering. Carrier-related
investment may be calculated based on either account averages or product
specific plant engineering and installation hours. Total labor costs shall be
computed by multiplying the account average or product specific work time by
the appropriate labor hours. Hourly labor rates shall include the operational
wages, benefits, paid absence, tools, and miscellaneous expenses.
d) Utilization factors. The utilization factor measures the
usable capacity of a capital resource pursuant to the definition of usable
capacity in Section 791.20(n). Investment shall be adjusted to reflect the
usable capacity by dividing the dollar amount of investment by the utilization
factor estimated pursuant to this Section.
