Segment Information

Note 12. Segment Information

Prior to September 16, 2011, the Company had three reportable operating segments based on the nature of its product lines: Production Monitoring, AutoData Systems, and Investments. The AutoData Systems segment was sold on September 16, 2011 as described in Note 10. The operations of that segment are presented as discontinued operations in the accompanying financial statements and are excluded from the presentation of segment information from continuing operations in this note. The reclassification of AutoData Systems to discontinued operations had no impact on the results of operations presented for the Production Monitoring or Investments segments.

As of December 31, 2011, the Company has two reportable operating segments: Production Monitoring and Investments. The Production Monitoring Division manufactures and markets a complete line of production monitoring equipment, in particular speed monitoring and motor control systems for industrial machinery. ESI Investment Company holds investments in marketable and non-marketable securities.

The accounting policies of the segments are the same as those described in Note 1. In evaluating segment performance, management focuses on sales and income before taxes. The Company has no inter-segment sales.

The following is financial information relating to the continuing operating segments:
