Depreciation, Amortization, and Depletion

Explanation:

1. Depreciation is an accounting technique used to account for the loss of value of physical or tangible assets. It measures the loss in the monetary value of physical assets. Examples of physical or tangible assets include motor vehicles, plants and machinery, and buildings.

The loss in value results from usage represented by wear and tear, aging, and obsolescence. Depreciation spreads the cost of an asset over its useful life. The depreciation amount is charged to the income statement in every year of its useful life.

2. Amortization is the method used to lower the book value of intangible assets over time. Intangible assets contrast tangible assets or physical assets. They are assets that cannot be touched or seen. They include trademarks, patents, and licenses.

Amortization is in line with accounting principles of matching expenses with income in the period in which they are incurred. Amortization is also used to lower the book value for loans.

3. Depletion is the technique used to lower the value of natural resources over time. Depletion does not account for the loss in value due to usage and age but due to exhaustion of natural resources reserves. Depletion expense is used by oil and gas drillers, miners, and other firms engaged in the extraction of natural resources.
