Goodwill and Intangible Asset
Note 3.                          Goodwill and Other Intangible Assets

The goodwill balance was $14.9 million as of September 30, 2015 and December 31, 2014.  Goodwill is subject to annual impairment tests and if triggering events are present before the annual tests, we will assess impairment.  As of September 30, 2015, no impairment charges were taken.

Other intangible assets consist primarily of customer relationship enhancements.  Other 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 and $1.7 million for each of the three and nine months ended September 30, 2015 and 2014.  The remaining balance of $1.7 million will be fully amortized as of June 30, 2016.  Other 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 September 30, 2015, no impairment charges were taken.
