SEGMENT REPORTING AND GEOGRAPHIC INFORMATION
 
(a)
General Information

As of December 31, 2012, the Company’s operations are based upon four operating segments:
 
(1)
Energy & Security Sonar Solutions whose activities are focused on the following areas – sonar and acoustic related solutions for energy, defense and commercial markets and includes other real-time and embedded hardware & software development and production. Energy & Security Sonar Solutions activities are provided through the Company’s DSIT Solutions Ltd. subsidiary.

(2)
The Company’s GridSense segment provides Smart Grid Distribution Automation products and services.  As these activities were acquired in May 2010 (see Note 3(b)(i)), the results for 2010 are for the partial period since acquisition. The Company’s GridSense segment also includes the activities of OMI which was acquired in May 2010 (see Note 3(b)(ii)).

(3)
The Company’s USSI segment provides Energy and Security Sensor Systems services.  USSI was effectively acquired in February 2010 (see Note 3(c)). USSI's primary focus is to develop and produce fiber optic sensing systems for the energy and security markets.  As these activities were effectively acquired in February 2010, the results for 2010 are for the partial period since acquisition.

(4)
The Company's Power Generation Monitoring segment provides products and services which deliver critical, real-time machine information to customers, while its Smart Service™ software provides remote diagnostics that give users real control over their equipment. These activities are performed through the Company's OmniMetrix subsidiary. As these activities were acquired in February 2012 (see Note 3(a)), there are no comparative results reported for these activities for the years ended December 31, 2010 or 2011.
  
During 2012, each of the four abovementioned activities represented a reportable segment. In addition, our “Other” segment represents certain IT activities (protocol management software for cancer patients and billing software) and outsourced consulting activities performed by our DSIT subsidiary as well as Cathodic Protection activities in our OmniMetrix subsidiary, that do not meet the quantitative thresholds and which may be combined for reporting under applicable accounting principles.

The Company’s reportable segments are strategic business units, offering different products and services and are managed separately as each business requires different technology and marketing strategies.  Similar operating segments are aggregated into one reportable segment.

(b)
Information about Profit or Loss and Assets

The accounting policies of all the segments are those described in the summary of significant accounting policies.  The Company evaluates performance based on net income or loss before taxes.
 
The Company does not systematically allocate assets to the divisions of the subsidiaries constituting its consolidated group, unless the division constitutes a significant operation.  Accordingly, where a division of a subsidiary constitutes a segment that does not meet the quantitative thresholds of applicable accounting principles, depreciation expense is recorded against the operations of such segment, without allocating the related depreciable assets to that segment.  However, where a division of a subsidiary constitutes a segment that does meet the quantitative thresholds, related depreciable assets, along with other identifiable assets, are allocated to such division.
