Significant Risk Concentrations	8. Significant Risk Concentrations *Significant Customer* No customer accounted for 10% or more of total revenue for the three or six months ended June 30, 2013 or June 30, 2012. No customer had an accounts receivable balance which was 10% or more of the total accounts receivable at June 30, 2013. Bluebird Soft, Inc., a designer and manufacturer of handheld mobile devices, had an accounts receivable balance of $2.1 million, or 13% of total accounts receivable, as of December 31, 2012, all of which was subsequently collected. No other customer accounted for 10% or more of total accounts receivable at December 31, 2012. *Significant Supplier* We have ODAs with Microsoft which enable us to sell Microsoft Windows Embedded operating systems to our customers in the United States, Canada, the Caribbean (excluding Cuba), Mexico, the European Union and the European Free Trade Association, which expire on June 30, 2014. We also have ODAs with Microsoft which allow us to sell Microsoft Windows Mobile operating systems in the Americas, Japan, Taiwan, Europe, the Middle East, and Africa. Our current distribution agreements related to Windows Mobile expire in June 2014. Our rights to distribute Windows Mobile operating systems in Korea ended on October 31, 2012. We sold $494,000 and $1.7 million of Windows Mobile operating systems in Korea during the three and six months ended June 30, 2012. Software sales under these agreements constitute a significant portion of our software revenue and total revenue. These agreements are typically renewed 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. Under this rebate program we earned $349,000 and $569,000 during the three and six months ended June 30, 2013, respectively, and $184,000 and $413,000 during the three and six months ended June 30 2012, respectively. These rebates are accounted for as a reduction in software cost of revenue.
