What it is:
How it works (Example):
Let's assume Company XYZ owns the patent on a piece of technology, and that patent lasts 15 years. If the company spent $15 million to develop the technology, then it would record $1 million each year for 15 years as amortization expense on its income statement.
Alternatively, let's assume Company XYZ has a $10 million loan outstanding. If Company XYZ repays $500,000 of that principal every year, we would say that $500,000 of the loan has amortized each year.
Why it Matters:
The length of time over which various intangible assets are amortized vary widely, from a few years to as many as 40 years. As a general rule, an asset should be amortized over its estimated useful life, or the maturity or loan period in the case of a bond or a loan. If an intangible asset has an indefinite life, such as goodwill, it cannot be amortized.
