* Accumulated amortization ** Results for the Cathodic Protection segment are included in "Other" in Segment Reporting (see Note 10). The composition of intangibles in each of the Company's segments are as follows:
Segment |  | Type of Intangible
Energy & Security Sonar Solutions |  | Naval technologies
GridSense |  | Software, customer relationships and trade name
USSI |  | Sensor technologies and license
Power Generation Monitoring |  | Technologies, customer relationships and non-compete agreements
Cathodic Protection* |  | Technologies and customer relationships
* The Cathodic Protection segment is included in "Other" in Segment Reporting (see Note 10). During the second quarter of 2013, a customer with whom OmniMetrix had a significant on-going relationship at the time of the Company's acquisition of OmniMetrix in February 2012, indicated that they would be disconnecting all of their power generator monitoring units over a period of time. Accordingly, the Company recorded an impairment of the customer relationship intangible asset associated with that customer in its Power Generation Monitoring segment of $1,116. Amortization expense for the six months ended June 30, 2012 and 2013 amounted to $456 and $497, respectively. Amortization expense with respect to intangible assets is estimated to be $917, $848, $756, $756 and $754 for each of the years ending June 30, 2014 through 2018.
