Intellectual property assets are:

A) depreciated.
B) depleted.
C) amortized.
D) expensed.

Intellectual property assets are typically amortized over their useful life because they are intangible assets. Amortization is the process of gradually writing off the initial cost of an intangible asset over a period of time, reflecting the asset's consumption, expiration, obsolescence, or other decline in value as a result of use or the passage of time.
