Goodwill and Intangible Assets Disclosure [Text Block]

(4)	GOODWILL AND INTANGIBLE ASSETS

Goodwill and intangible assets on our balance sheets are the result of our acquisitions of Sigma Systems Corp. ("Sigma") in October 2008 and Thermonics, Inc. ("Thermonics"), a division of Test Enterprises, Inc. in January 2012.

Goodwill

All of our goodwill is allocated to our Thermal Products segment. There was no change in the amount of the carrying value of goodwill for the three months ended March 31, 2016.

The following tables provide further detail about our intangible assets as of March 31, 2016 and December 31, 2015:

We generally amortize our finite-lived intangible assets over their estimated useful lives on a straight-line basis, unless an alternate amortization method can be reliably determined. Any such alternate amortization method would be based on the pattern in which the economic benefits of the intangible asset are expected to be consumed. None of our intangible assets have any residual value.

Total amortization expense for the three months ended March 31, 2016 and 2015 was $59 and $73, respectively. The following table sets forth the estimated annual amortization expense for our finite-lived intangible assets for each of the next five years:

2016 (remainder)	$	170

2017	$	212

2018	$	65

2019	$	39

2020	$	30
