13. Segment and Geographic Information

Segment Information

Real Goods Solar was deconsolidated on December 31, 2011, and, thus, the segment information below reports RSOL as an equity method investment for 2012 and as a consolidated subsidiary for 2011 and 2010. Since RSOL’s deconsolidation, we manage our business and aggregate our operational and financial information in accordance with two reportable segments. The direct to consumer segment contains direct response marketing program, catalog, Internet, retail store and subscription channels; and the business segment comprises retailer, media distribution, and corporate account channels.

Although we are able to track revenue by sales channel, the management, allocation of resources and analysis and reporting of expenses is presented on a combined basis, at the reportable segment level. Contribution margin is defined as net revenue less cost of goods sold and total operating expenses.

Financial information for these three segments was as follows:

The following is a reconciliation of reportable segments’ assets to our consolidated total assets. Other unallocated corporate amounts are comprised of cash, current and deferred income taxes, and property and equipment.
