Goodwill and Other Intangible Assets
Note 4.  Goodwill and Other Intangible Assets

The carrying value of our goodwill and intangible assets increased during the first quarter of 2012 due to our acquisition of IdeaOne Telecom which closed on March 1, 2012. Goodwill was $29,034,000 as of March 31, 2012 compared to $27,303,000 at December 31, 2011. We have goodwill in all three of our operating units: Fiber and Data Segment goodwill resulted from our acquisition of IdeaOne Telecom in 2012, CP Telecom in 2009 and Enventis Telecom in 2005. Equipment Segment goodwill also resulted from our acquisition of Enventis Telecom and Telecom Segment goodwill resulted from our acquisition of Heartland Telecommunications in 1997.

We test acquired goodwill for impairment annually by first completing a qualitative analysis to determine whether or not it is more likely than not that the fair value of a reporting unit exceeds its carrying amount. We also test goodwill for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of an entity below its carrying value. We completed our annual impairment test for acquired goodwill as of December 31, 2011, which resulted in no impairment charges to goodwill. In the first three months of 2012, there was no event or change in circumstance that would have more likely than not reduced the fair value below its carrying value.

Intangible assets with finite lives are amortized over their respective estimated useful lives to their estimated residual value.  Identifiable intangible assets that are subject to amortization are evaluated for impairment on an annual basis or if an event occurs or a change in circumstances indicates the carrying value may not be recoverable. Our acquisition price for IdeaOne Telecom included intangible assets of $3,200,000 in customer relationships and $100,000 of other intangibles. The components of intangible assets are as follows:

Amortization expense related to the definite-lived intangible assets was $138,000 and $88,000 for the three months ended March 31, 2012 and 2011, respectively.
