Definitions:

Units-Of-Production

A depreciation method that allocates the cost of an asset over its useful life based on the number of units it produces.

Depreciable Cost

The initial cost of an asset minus its salvage value, which is the amount that can be depreciated over the life of the asset.

Residual Value

The approximated price an asset will bring in at the conclusion of its operational life when it is sold.

Straight-Line Basis

A method of calculating depreciation or amortization that spreads the asset's cost evenly across its useful life.
