Intangible assets

Note 5. Intangible Assets

Amortization expense related to intangible assets was $866,000 in 2011, $364,000 in 2010 and $177,000 in 2009.

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):
