Goodwill and Intangible Asset
Note 4. Goodwill and Intangible Asset

The goodwill balance was $14.9 million as of March 31, 2013 and December 31, 2012.  Due to the finalization of the purchase price allocation related to the acquisition of ITL in the first quarter of 2012, the goodwill balance was adjusted by $142,000 from $15.1 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 was $0.6 million for the three months ended March 31, 2013 and 2012.  Amortization expense will be $2.3 million annually for the next 3 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 March 31, 2013, no impairment charges were taken.
