Utility Plant
Utility plant is stated at original cost. Cost includes direct labor, materials, AFUDC (see description below) and indirect charges for such items as transportation, supervision, pension, and other fringe benefits related to employees engaged in construction activities. When depreciable units of utility plant are retired, any cost associated with retirement, less any salvage value or proceeds received will be charged to a regulated retirement liability. Maintenance, repairs, and replacement of minor items of plant are charged to expense as incurred.
In accordance with a rate order issued by the DEPSC, Artesian Water accrues an Allowance for Funds Used During Construction, or AFUDC. AFUDC, which represents the cost of funds devoted to construction projects through the date the project is placed in service, is capitalized as part of construction work in progress. The rate used for the AFUDC calculation is based on Artesian Water's weighted average cost of debt and the rate of return on equity authorized by the DEPSC. The rate used to capitalize AFUDC in 2013, 2012, and 2011 was 8.2%.
