Note 11.  Business Segment Information

Management views the Company as operating in two major business segments: Power and Energy Group, and All Other operations.

The Power and Energy Group develops, produces, and sells battery systems.  The All Other group consists of the remaining portions of the previous Life Sciences and Performance Materials groups.  

During the six months ended June 30, 2013, the Company and its affiliates received a total of $4,039,000 in cash payments for its various Power and Energy Group projects. Of this received amount, $2,649,000 was associated with contractual milestone payments for our larger utility-scale energy storage system projects, two of which have not been recognized in our reportable segment data for the year, as the related contracts are recognized under the completed contract method.

Reportable segment data reconciled to the consolidated financial statements as of the three and six months ended June 30, 2013 and June 30, 2012 is as follows:
