Study Objective 1 - Describe how the Cost Principle Applies to Plant Assets. Plant assets are resources that have physical substance (a definite size and shape), are used in the operations of a business, and are not intended for sale to customers.f a cost is not included in a plant asset account, then it must be expensed immediately. Such costs are referred to as revenue expenditures. Costs that are not expensed immediately, but are instead included in a plant asset account are referred to as capital expenditures.
Plant Assets and Depreciation. This lesson explains a little more about how depreciation expense is calculated. It also shows the other significant events in the life of plant assets: the purchase and retirement of those assets.Depreciation expense spreads the cost of major equipment and assets over a period of time that spans a number of years.Amortization is used to allocate the cost of intangible assets, such as patents, copyrights, trademarks, and franchises.he government allows you to use the cost of plant assets to offset income. You recover your cost a little bit at a time, over a number of years. Each year you reduce your income tax expense, by an amount relative to the cost recovery amount for that year.
