The process of spreading the costs of long-lived assets such as buildings and equipment over the total number of accounting periods in which they are expected to be used is called

Depreciation

Explanation:

Depreciation is the process of reallocation of tangible assets over its useful life. Depreciation is an expense which is charged on the entire cost of a long-term tangible fixed asset. The depreciation expense is computed by reducing the scrap value of the asset from its cost and dividing it by the entire useful life of the asset. There are several methods used to depreciation tangible assets such as straight-line method, MACRS, double declining etc. Salvage value is the expected value of the asset at the end of its life. For example, if an asset has been purchased at $110,000 with a useful life of 5 years and salvage value of $10,000 then using straight-line depreciation per year over 5 years will be ($110,000-$10,000)/5 = $20,000.
