Operating segments are defined as (i) components of an enterprise that engage in business activities from which they may earn revenue and incur expense, (ii) have operating results that are regularly reviewed by the enterprise’s chief operating decision maker to make decisions about resources to be allocated to the segment and assess its performance, and (iii) for which discrete financial information is available. Our Chief Executive Officer is our chief operating decision maker (“CODM”) and reviews financial information at the operating segment level and is responsible for making decisions about resources allocated amongst the operating segments based on actual results. Our operating segments are aligned with how the Company, including our CODM, manages the business. As such, our reportable operating segments are the Wholesale segment and the Retail segment.

Our wholesale and retail operating segments represent strategic business areas of our vertically integrated enterprise that operate separately and provide their own distinctive services. This vertical structure enables us to offer our complete line of home furnishings and accents more effectively while better controlling quality and cost. We evaluate performance of the respective segments based upon sales and operating income.

Wholesale Segment. The wholesale segment, which accounted for 19.0% of net sales during fiscal 2021, is principally involved in the development of the Ethan Allen brand and encompasses all aspects of design, manufacturing, sourcing, marketing, sale and distribution of our broad range of home furnishings and accents. Our wholesale segment net sales include sales to our retail segment, which are eliminated in consolidation, and sales to our independent retailers and other third parties. Wholesale revenue is generated upon the sale and shipment of our products to our retail network of independently operated design centers, Company-operated design centers and other contract customers. Sales to ten of our largest customers accounted for 22.2% of revenues within our wholesale segment during fiscal 2021. Our ten largest customers were all within our wholesale segment and represent 13.7% of our consolidated net sales in fiscal 2021. These customers are the GSA and nine independent retailers.

Retail Segment. The retail segment, which accounted for 81.0% of net sales during fiscal 2021, sells home furnishings and accents to clients through a network of Company-operated design centers. Retail revenue is generated upon the retail sale and delivery of our products to our retail customers through our network of retail home delivery centers. Retail profitability reflects (i) the retail gross margin, which represents the difference between the retail net sales price and the cost of goods, purchased from the wholesale segment, and (ii) other operating costs associated with retail segment activities. As of June 30, 2021, the Company operated 141 design centers within our retail segment.

The accounting policies of the operating segments are the same as those described in Note 3, Summary of Significant Accounting Policies. We account for intersegment sales transactions between our segments consistent with independent third-party transactions, that is, at current market prices. As a result, the manufacturing profit related to sales to our retail segment is included within our wholesale segment. Operating income realized on intersegment revenue transactions is therefore generally consistent with the operating income realized on our revenue from independent third-party transactions. Segment operating income is based on profit or loss from operations before interest and other financing costs, other income (expense), net and income taxes. Sales are attributed to countries on the basis of the customer's location.
