# Depreciation and Amortization Explained | CFA Level I FSA

Welcome back! In this lesson, we’ll dive into the accounting principles for depreciation and amortization expenses. Let’s start with a quick refresher from our previous lesson on inventory expense recognition.

## Period Costs and Depreciation and Amortization

Not all expenses can be directly tied to revenue generation, such as period costs (e.g., administrative costs and rent). These are expensed in the period incurred. Another type of expense commonly incurred is depreciation and amortization costs.

When a company acquires long-lived assets like equipment expected to provide future economic benefits beyond one accounting period, the cost to acquire the asset has to be accounted for. Depreciation is used for tangible assets, while amortization is used for intangible assets.

## Calculating Depreciation and Amortization

So, how do we determine the amount to depreciate or amortize for each period?

Accelerated methods like the double declining balance method are not used for amortization. For intangible assets with a finite life, the straight-line method is the most commonly used.

EXAMPLE

The shoe retailer recently purchased a delivery truck at a cost of \$50,000. The truck is expected to be in use for the next 5 years, where it can reasonably be resold for \$20,000. Calculate the depreciation expense for each year of the truck’s useful life using the straight-line method.

Using the straight-line method, we get an annual depreciation of \$6,000 for the next 5 years. What if we use the double-declining balance method?

For the first year, we get a depreciation of \$20,000. The net book value of the asset drops to \$30,000. In the second year, the asset is supposed to be depreciated by \$12,000. However, the residual value is \$20,000, so the depreciation is limited to just \$10,000 in the second year. Since the net book value has reached the residual value by the end of the second year, the depreciation expense is 0 for the remaining years.

## Impairment and Subjectivity in Depreciation and Amortization

Intangible assets with indefinite lives, like goodwill, are not amortized but must be tested for impairment at least annually. If the asset value is impaired, an expense equal to the impairment amount is recognized.

When examining a company’s depreciation and amortization expense, an analyst should look out for areas of subjectivity, such as the method chosen for depreciation or estimating a higher than usual residual value. Both of these can result in higher current net income, which can be considered aggressive accounting.

That’s all for depreciation and amortization expenses! In our next lesson, we’ll explore non-recurring and non-operating items in the income statement. See you then!
