Section 712.15 Incidental
Activities
a) This Part requires that cost allocation procedures reflect the
existence of activities in each carrier that are accorded incidental accounting
treatment and allowed to remain on the regulated books of the business. Each
carrier is required to have on file at the carrier's headquarters and available
to Commission Staff upon request a description of each activity that is
accorded this treatment. "Incidental activities" include, but are
not limited to, items such as land and building space rental, cable locating,
and pole contact rental. (See 83 Ill. Adm. Code 710.14 and 710.23.)
b) Incidental activities are those that meet the following four conditions.
1) The activity is not a line of business;
2) The activity is an outgrowth of regulated operations;
3) There is little additional financial or business risk to the
regulated operation in providing the activity, as determined by the effect on
the capital investments and requirements; and
4) The activity utilizes an insubstantial commitment of
investment or resources of the carrier, as determined by the capital
investments and the service obligations of the carrier.
