11. SEGMENT REPORTING

We report selected information about operating segments in a manner consistent with that used for internal management reporting. We classify our solid waste operations on a geographic basis through regional operating segments. Revenues are derived mainly from collection, transfer, disposal, landfill, landfill-gas-to energy and recycling services in the northeastern United States. Our revenues in the Recycling segment are derived from municipalities and customers in the form of processing fees, tipping fees and commodity sales. Organics services, ancillary operations, major customer accounts, discontinued operations, and earnings from equity method investees are included in our “Other” reportable segment. Segment data for the three months ended July 31, 2012 has been revised to properly align with internal management reporting, which has been modified in the three months ended July 31, 2013 to move organics services from the Eastern region to the Other segment to reflect changes in management structure as these services have become integral to service offerings across our broader geographic solid waste footprint.
