Rate Base Description
Summarization The purpose of this schedule is to illustrate the components of rate base and provide support for
recorded year 2013, estimated years 2014 and 2015, and Test Year 2016. Rate base is computed
on a weighted average basis. The primary components of weighted-average rate base are Plant-
in-Service, Non-Interest Bearing Construction Work-in-Progress, Materials and Supplies, and
Working Cash. This gross rate base is then reduced by Customer Advances for Construction
(CAC), Deferred Revenue (ITCC), Accumulated Depreciation Reserve, and Accumulated
Deferred Taxes (Plant and CIAC) to achieve a final weighted-average depreciated rate base.
Plant Balance
Plant-in-Service represents gross fixed assets used in utility operations with an expected
economic and physical life greater than one year from the date of service.
Accumulated Depreciation
Accumulated Depreciation Reserve represents weighted average accumulated book depreciation
reserve which includes a summation of depreciation accrual charges adjusted for plant
retirements, net salvage, and other adjustments or transfers as prescribed by the FERC Uniform
System of Accounts.

Construction Work-in-Progress (Non-Interest Bearing)
Construction-Work-in-Progress (Non-Interest Bearing) represents smaller project costs of plant
in construction not subject to the computation of allowance for funds used during construction
(AFUDC). The non-interest bearing work-in-progress amount represents projects completed and
placed in service within 30 days of construction or purchase (i.e. capital tools).
Material and Supplies
Materials and supplies are costs of purchased materials primarily used as current inventory for
construction, operation, maintenance, merchandising, jobbing, and contract work.
Working Cash
Working cash represents operational cash requirements contributed by our investors resulting
from evaluation of balance sheet items and lead-lag study. Working cash is included in rate base
to compensate our investors for the funds advanced by them. These funds are used to pay
operating expenses in advance of receiving customer revenues and for working funds for day-to-
day operational requirements.
Customer Advances for Construction (CAC)
Customer Advances for Construction (CAC) represents refundable cash advances received from
customers who have requested the installation of new business mains and services. These cash
advances are subject to refund when new customers and appliances are added to these lines as
mandated by the CPUC and described in SoCalGas Tariff Rules 20 and 21.
