Final answer:
The residual value of an intangible asset is typically zero, as these assets do not have salvage value and do not retain market or resale value after full amortization.
Step-by-step explanation:
The residual value of an intangible asset is usually considered to be zero. Intangible assets, such as patents, copyrights, trademarks, and goodwill, do not have a salvage value as tangible assets do. Instead, these assets are typically amortized over their useful lives, and after full amortization, they are expected to provide no residual value.
Unlike tangible assets where salvage value is considered, intangible assets typically do not have a market or resale value at the end of their useful lives. Therefore, the residual value is not calculated as cost less amortization, the fair value at the date acquired, or cost minus salvage.
