ASTM E2453-19

1.1 This practice covers the establishment of a process consensus model for determining the life-cycle cost (LCC) of property assets owned or used by an entity.

1.2 Real and personal property assets may include capital (fixed) assets and movable assets including customer-supplied assets, rental/leased assets, contract/project direct-purchased assets, or expense items.

1.3 Asset service lives can be divided into three distinct stages, each with several separate yet interrelated substages: acquisition, utilization, and disposition. These primary stages are not intended to be all-encompassing but are offered as the basis for establishing LCC.

1.4 This practice is expected to be primarily used for considering the life-cycle cost of personal property, however, the concept can and should be used for various types of assets including personal, real, tangible, and intangible.

1.5 This practice does not supersede applicable generally accepted accounting principles but is intended to be consistent with the accounting principles particularly in the area of internal controls (see the GAO Green Book) and processes and requirements for estimating. Some life-cycle cost estimating may be required for accounting purposes. (See AS 2501.)
