Goodwill and Intangible Asset
Note 4. Goodwill and Intangible Asset

As of December 31, 2011, the balance of goodwill was $15.1 million.  Due to the finalization of the purchase price allocation in the first quarter of 2012, the goodwill balance was adjusted by $142,000 to $14.9 million.

Other intangible assets consist primarily of customer relationship enhancements. Intangible assets are amortized on a straight-line basis over their estimated useful lives of 5 years.  The amortization is based on a forecast of approximately equal annual customer orders over the 5-year period.  Amortization expense for 2012 and 2011 was $2.3 million and $1.1 million, respectively.  Amortization expense will be $2.3 million annually for the next 3.5 years.  Intangible assets are subject to impairment review if there are events or changes in circumstances that indicate that the carrying amount is not recoverable.  As of December 31, 2012, no impairment charges were taken.
