Goodwill

During 2014, we adjusted our purchase price allocation related to the acquisition of MISCOR, resulting in net additional goodwill of $1,069 for our Infrastructure Solutions segment, which increased the segment’s goodwill to $6,362, with offsetting adjustments to certain assets and liabilities of the acquired entity.  This additional goodwill of $1,069 is the result of the completion of our analysis of the tax basis of the acquired property, plant and equipment, which resulted in the recording of an additional deferred tax liability of $560.  Additionally, we completed our valuation of the acquired inventory, resulting in a $311 reduction in the estimated value previously attributed to work in process inventory. We also identified additional current liabilities of $198, resulting in a further increase to goodwill.

Based upon the results of our annual impairment analysis, the fair value of our Infrastructure Solutions segment exceeded the book value, and warranted no impairment. We evaluated goodwill attributable to our Residential segment qualitatively, and have concluded no impairment is indicated.

Intangible assets consist of the following:
