Goodwill

Goodwill balances at June 30, 2012 and December 31, 2011 consisted of $42,908 from the acquisition of D3 Technologies, Inc. ("D3") in July 2007 and $6,194 from the acquisition of Integrated Technologies, Inc. ("Intec") in January 2009.  These goodwill balances are not deductible for tax purposes.

 Intangible Assets
 
Intangible assets primarily consist of trademarks and customer intangibles resulting from the acquisitions of Intec and D3.  The trademark of $4,222 that resulted from the acquisition of D3 was determined to have an indefinite life.  The remaining trademark resulted from the acquisition of Intec and has a weighted average estimated useful life of 6.7 years.  Customer intangibles have an estimated useful life of 15 to 16 years.  Other intangible assets have a weighted average estimated useful life of 4.7 years.  The carrying values were as follows:
