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. falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for any concentrations existing at the date of the financial statements that make an entity vulnerable to a reasonably possible, near-term, severe impact.
