SEGMENT REPORTING AND GEOGRAPHIC INFORMATION [Abstract] |
Schedule of Segment Reporting Information, by Segment [Table Text Block] | SEGMENT REPORTING AND GEOGRAPHIC INFORMATION
(a) | General Information
As of December 31 2011, the Company’s operations are based upon three 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 4(a)(ii)), there are no comparative results reported for these activities for the year ended December 31, 2009. The Company’s GridSense segment also includes the activities of OMI which was acquired in May 2010 (see Note 4(a)(iii)).
(3) | The Company’s USSI segment provides Energy and Security Sensor Systems services. USSI was effectively acquired in February 2010 (see Note 4(b)). 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, there are no comparative results reported for these activities for the year ended December 31, 2009.
Other operations include various operations in DSIT that do not meet the quantitative thresholds 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. The following tables represent segmented data for the years ended December 31, 2011, 2010 and 2009:
