What is Obsolescence?


Share This...


Obsolescence is a reduction in the utility or value of an asset caused by advancements in technology, changes in market demand, or other environmental factors. This usually happens when a newer, more efficient, or more appealing product or method comes onto the market, making the older asset less desirable or less useful.

There are two main types of obsolescence:

  • Functional Obsolescence: This occurs when a newer, more efficient product or process becomes available, making the old one less productive or useful. An example might be a piece of machinery in a factory that is still operational but is much less efficient than newer models.
  • Economic Obsolescence: This refers to a decrease in the value of an asset caused by external factors, such as changes in market conditions or legal regulations. An example might be a decline in the value of a coal-fired power plant due to the implementation of stricter environmental regulations or the development of cheaper renewable energy sources.

Obsolescence is a key consideration in the depreciation of fixed assets and in inventory management. Accountants must estimate the useful life of an asset and the rate at which it will become obsolete in order to calculate depreciation expense accurately. Similarly, businesses must manage their inventories effectively to avoid holding goods that could become obsolete and lose their value.

Example of Obsolescence

Let’s take a look at both types of obsolescence with some examples:

Functional Obsolescence: Imagine a company that owns a piece of manufacturing equipment. The equipment is in good working condition and is capable of producing 1,000 units per hour. However, a new piece of equipment becomes available on the market that can produce 2,000 units per hour with the same input. The older machine has become functionally obsolete, because even though it still works, the newer machine can do the same job more efficiently.

Economic Obsolescence: Consider a company that manufactures DVD players. Over time, as more people start streaming movies and shows online, demand for DVD players drops significantly. The company’s inventory of DVD players becomes economically obsolete because changes in consumer preferences have reduced their value. The company may need to sell them at a discount or even write off the remaining inventory as a loss.

It’s worth noting that obsolescence can have a significant impact on a company’s financials. It may require write-downs or impairment charges, which can affect the company’s reported assets and profits. This is why businesses often need to plan for obsolescence and incorporate it into their strategies for depreciation and inventory management.
