Note 6. Segment Reporting Prior to the fourth quarter of Fiscal 2019, we had three reportable segments: BNC, MBS, and DSS. During the fourth quarter of Fiscal 2019, in an effort to streamline our retail go-to-market strategy, reinforce our company branding, and more efficiently focus our product development efforts, we realigned our business and sales organization into the following three reportable segments: Retail, Wholesale and DSS. The Retail Segment combines the operations of the former BNC segment with MBS Direct (from the former MBS segment), the Wholesale Segment is comprised of the MBS wholesale business (from the former MBS segment), and the DSS Segment remains unchanged. Additionally, unallocated shared-service costs, which include various corporate level expenses and other governance functions, continue to be presented as Corporate Services. We identify our segments in accordance with the way our business is managed (focusing on the financial information distributed) and the manner in which our chief operating decision maker allocates resources and assesses financial performance. The following summarizes the three segments. For additional information about this segments operations, see Part I - Item 1. Business in our Annual Report on Form 10-K for the year ended April 27, 2019 . Retail The Retail Segment operates 1,436 college, university, and K-12 school bookstores, comprised of 772 physical bookstores and 664 virtual bookstores. Our bookstores typically operate under agreements with the college, university, or K-12 schools to be the official bookstore and the exclusive seller of course materials and supplies, including physical and digital products. The majority of the physical campus bookstores have school-branded e-commerce sites which we operate and which offer students access to affordable course materials and affinity products, including emblematic apparel and gifts. The Retail Segment also offers inclusive access programs, in which course materials, including e-content, are offered at a reduced price through a course materials fee, and delivered to students on or before the first day of class. Additionally, the Retail Segment offers a suite of digital content and services to colleges and universities, including a variety of open educational resource-based courseware. Wholesale The Wholesale Segment is comprised of our wholesale textbook business and is one of the largest textbook wholesalers in the country. The Wholesale Segment centrally sources, sells, and distributes new and used textbooks to approximately 3,500 physical bookstores (including our Retail Segment's 772 physical bookstores) and sources and distributes new and used textbooks to our 664 virtual bookstores. Additionally, the Wholesale Segment sells hardware and a software suite of applications that provides inventory management and point-of-sale solutions to approximately 400 college bookstores. DSS The Digital Student Solutions (DSS) Segment includes direct-to-student products and services to assist students to study more effectively and improve academic performance. The DSS Segment is comprised of the operations of Student Brands, LLC, a leading direct-to-student subscription-based writing services business, and bartleby  , a direct-to-student subscription-based offering providing textbook solutions, expert questions and answers, tutoring and test prep services. Corporate Services Corporate Services represent unallocated shared-service costs which include corporate level expenses and other governance functions, including executive functions, such as accounting, legal, treasury, information technology, and human resources. Intercompany Eliminations The eliminations are primarily related to the following intercompany activities:  The sales eliminations represent the elimination of Wholesale sales and fulfillment service fees to Retail and the elimination of Retail commissions earned from Wholesale, and  These cost of sales eliminations represent (i) the recognition of intercompany profit for Retail inventory that was purchased from Wholesale in a prior period that was subsequently sold to external customers during the current period and the elimination of Wholesale service fees charged for fulfillment of inventory for virtual store sales, net of (ii) the elimination of intercompany profit for Wholesale inventory purchases by Retail that remain in ending inventory at the end of the current period. Our international operations are not material and the majority of the revenue and total assets are within the United States.
