20. SEGMENT REPORTING

The company’s segments are currently separated primarily by the different delivery methods each segment uses for its respective product deliveries. The DSD Segment’s products are delivered fresh to customers through a network of IDPs who are incentivized to grow sales and to build equity in their distributorships. The Warehouse Segment ships fresh and frozen products to customers’ warehouses nationwide. Our bakeries fall into either the DSD Segment or Warehouse Segment depending on the primary method of delivery used to sell that bakery’s products. The bakeries within each segment produce products that are sold externally and internally. Internal sales are to bakeries within the producing bakery’s segment or to the other segment. Sales between bakeries are transferred at standard cost.

The company evaluates each segment’s performance based on income or loss before interest and income taxes, excluding unallocated expenses and charges, which the company’s management deems to be an overall corporate cost or a cost not reflective of the segment’s core operating businesses.
