Intangible Assets

D. Intangible Assets

Intangible assets are recorded at cost less accumulated amortization which is included in engineering, selling and administrative expenses in the accompanying unaudited condensed consolidated statements of operations. Amortization is computed for financial reporting purposes using the straight-line method over the estimated useful lives of the assets, which range up to 10 years. The intangible assets consist of intellectual property and goodwill. The net carrying value of the amortizable intangible assets was $532,000 and $588,000 as of September 30, 2017 and December 31, 2016, respectively. Goodwill, which is not amortizable, was $40,000 as of September 30, 2017 and December 31, 2016.

The estimated aggregate amortization expense for intangible assets, excluding goodwill, for the remaining portion of 2017 and each of the four succeeding years and thereafter is as follows (in thousands):

2017	$	19
2018		75
2019		75
2020		75
2021		75
Thereafter		213
Total	$	532
