Segment Reporting [Abstract] |
Segment Reporting | NOTE 16 – SEGMENT REPORTING Segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. The Company’s reportable segments, power industry services and telecommunications infrastructure services, are organized in separate business units with different management teams, customers, technologies and services. The business operations of each segment are conducted primarily by the Company’s wholly-owned subsidiaries – GPS and SMC, respectively. Presented below are summarized operating results and certain financial position data of the Company’s reportable continuing business segments for the years ended January 31, 2014, 2013 and 2012. The “Other” column includes the Company’s corporate and unallocated expenses. Fiscal Year Ended January 31, 2014
