Note 4. Intangible Assets

Amortization expense related to intangible assets was $16,000 and $1.0 million for the years ended December 31, 2017and 2016, respectively.

In December 2006, we acquired the use of a toll-free telephone number for cash consideration of $250,000. This asset has an indefinite useful life. The intangible asset is tested for impairment annually or more often if events or changes in circumstances indicate that the carrying value may not be recoverable.

The following table summarizes the components of intangible assets (in thousands):
