Significant Supplier We have OEM Distribution Agreements (“ODAs”) with Microsoft Corporation (“Microsoft”) which enable us to sell Microsoft Windows Embedded operating systems on a non-exclusive basis to our customers in the United States, Canada, Argentina, Brazil, Chile, Columbia, Mexico, Peru, Puerto Rico, the Caribbean (excluding Cuba), the European Union, the European Free Trade Association, Turkey and Africa, which expire on June 30, 2018. We also have ODAs with Microsoft, which allow us to sell Microsoft Windows Mobile operating systems in the Americas (excluding Cuba), Japan, Taiwan, Europe, the Middle East, and Africa, which also expire on June 30, 2018. Software sales under these agreements constitute a significant portion of our software revenue and total revenue. These agreements are typically renewed bi-annually, annually or semi-annually; however, there is no automatic renewal provision in any of these agreements. Further, these agreements can be terminated unilaterally by Microsoft at any time. Microsoft currently offers a rebate program to sell Microsoft Windows Embedded operating systems pursuant to which we earn money for achieving certain predefined objectives. In accordance with Microsoft rebate program rules, we allocate 30% of rebate values to reduce cost of sales, with the remaining 70% to offset qualified marketing expenses in the period the expenditures are incurred. Under this rebate program, we recognized $126,000 and $323,000 of rebate credits during the three and nine months ended September 30, 2017, respectively, compared to $78,000 and $287,000 during the three and nine months ended September 30, 2016, respectively, which were accounted for as reductions in cost of revenue. Additionally, during the three and nine months ended September 30, 2017, we received $185,000 and $558,000 in rebates, respectively, compared to $181,000 and $670,000 during the three and nine months ended September 30, 2016, respectively, which were accounted for as reductions in marketing expense. There was a balance of approximately $294,000 in outstanding rebate credits for which we qualified at September 30, 2017, which will be accounted for as reductions in marketing expense in the period in which qualified program expenditures are made. Microsoft implemented significant pricing changes for its embedded products effective January 1, 2016, including ending its design registration pricing discounts, terminating its OEM Volume Royalty Programs (“OVRP”) and changing the aggregate volume price structure and product royalties for existing embedded Windows products. In December 2015, Microsoft granted extensions for certain of the OVRPs through December 31, 2016, at which time the program ended.
