The depreciation method in which a plant asset's depreciation expense for a period is determined by applying a constant depreciation rate to the asset's beginning-of-period book value is called:

A) Book value depreciation.
B) Declining-balance depreciation.
C) Straight-line depreciation.
D) Units-of-production depreciation.
E) Modified accelerated cost recovery system (MACRS) depreciation.

Declining-Balance Depreciation

A method of accelerated depreciation where an asset loses value by a fixed rate, resulting in larger depreciation charges in the earlier years and smaller charges in the later years.

Depreciation Expense

The allocation of the cost of a tangible asset over its useful life, representing how much of an asset's value has been used up over a period.

Depreciation Rate

The percentage rate at which an asset is depreciated across its useful life, impacting how much of its cost is allocated as an expense each year.
