(13) Segment Information Our operations are classified into two operating segments: wholesale and retail. These operating segments represent strategic business areas of our vertically integrated business which, although they operate separately and provide their own distinctive services, enable us to more efficiently control the quality and cost of our complete line of home furnishings and accents. The wholesale segment is principally involved in the development of the Ethan Allen brand, which encompasses the design, manufacture, domestic and offshore sourcing, sale and distribution of a full range of home furnishings and accents to a network of independently operated and Ethan Allen operated design centers as well as related marketing and brand awareness efforts. Wholesale revenue is generated upon the wholesale sale and shipment of our product to all retail design centers, including those operated by Ethan Allen. The retail segment sells home furnishings and accents to consumers through a network of Company operated design centers and online through ethanallen.com. Retail revenue is generated upon the retail sale and delivery of our product to our customers. Inter-segment eliminations result, primarily, from the wholesale sale of inventory to the retail segment, including the related profit margin. We evaluate performance of the respective segments based upon revenues and operating income. While the manner in which our home furnishings and accessories are marketed and sold is consistent, the nature of the underlying recorded sales (i.e. wholesale versus retail) and the specific services that each operating segment provides (i.e. wholesale manufacturing, sourcing, and distribution versus retail selling) are different. Within each segment, we maintain revenue information according to each respective product line (i.e. case goods, upholstery, or home accents and other). A breakdown of wholesale segment sales by these product lines for the three and six months ended December 31, 2015 and 2014 is provided as follows:
