Commitments and Contingencies |
Commitments and Contingencies | Note 12. Commitments and Contingencies Indemnification Agreements We have entered into indemnification agreements with our directors and officers that require us to indemnify our directors and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of a culpable nature; to advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified; and to obtain directors’ and officers’ insurance if available on reasonable terms, which we currently have in place. Product Warranty We provide warranties for our products for a specific period of time, generally twelve months, against material defects. We provide for the estimated future costs of warranty obligations in cost of sales when the related revenue is recognized. The accrued warranty costs represent the best estimate at the time of sale of the total costs that we expect to incur to repair or replace product parts that fail while still under warranty. The amount of accrued estimated warranty costs are primarily based on historical experience as to product failures as well as current information on repair costs. On a quarterly basis, we review the accrued balances and update the historical warranty cost trends. The following table reflects the change in our warranty accrual which is included in “accrued liabilities” on the condensed consolidated balance sheets, during the three and six months ended June 30, 2016 and 2015 (in thousands):

Contractual Obligations We lease certain office space, warehouse facilities and equipment under long-term operating leases expiring at various dates through December 2025. The majority of our lease obligations relates to our lease agreement for the facility in Fremont, California with approximately 19,467 square feet, which expires in 2017. We have an option to extend the lease for an additional three years. We entered into a royalty agreement with a competitor effective December 3, 2010 with a term of eight years, terminating December 31, 2018. We and our related companies are granted a worldwide, nonexclusive, royalty bearing, irrevocable license to certain patents for the term of the agreement. We shall pay up to $7.0 million of royalty payment over eight years that began in 2011 based on future royalty bearing sales. This royalty agreement contains a clause that allows us to claim a credit, starting in 2013, in the event that the royalty bearing sales for the year are lower than a pre-determined amount set forth in this agreement. The following table summarizes our contractual obligations as of June 30, 2016 (in thousands):
|  | Payments due by period |
|  |  |  |  |  |  |  | 1-3 |  | 4-5 |  | More than |
Contractual Obligations |  | Total |  | Less than 1 year |  | years |  | years |  | 5 years |
Operating leases |  | $ | 475 |  | $ | 220 |  | $ | 131 |  | $ | 51 |  | $ | 73 |
Royalty agreement |  |  | 1,438 |  |  | 575 |  |  | 863 |  |  | — |  |  | — |
Total |  | $ | 1,913 |  | $ | 795 |  | $ | 994 |  | $ | 51 |  | $ | 73 |
Purchase Obligations with Penalties for Cancellation In the normal course of business, we issue purchase orders to various suppliers. In certain cases, we may incur a penalty if we cancel the purchase order. As of June 30, 2016, we do not have any outstanding purchase orders that will incur a penalty if cancelled by the Company. Legal Proceedings From time to time we may be involved in judicial or administrative proceedings concerning matters arising in the ordinary course of business. We do not expect that any of these matters, individually or in the aggregate, will have a material adverse effect on our business, financial condition, cash flows or results of operations. On February 27, 2015, the China State Administration of Work Safety updated its list of hazardous substances. The previous list, which was published in 2002, did not restrict the materials that we use in our wafers. The new list added gallium arsenide. As a result of the newly published list, we were required to obtain a permit by May 1, 2015 to continue to manufacture our gallium arsenide substrate wafers. We initiated discussions with the local district agency to obtain the requisite permit. On May 4, 2015, we were instructed by the local district agency that because we had not yet received the requisite permit, we should cease manufacturing our gallium arsenide substrate wafers or we should obtain permission to continue manufacturing our gallium arsenide substrate wafers from a municipal-level office, such as the Beijing municipal authority. The Beijing municipal authority accepted our application on May 7, 2015 and our application is still under review. There can be no assurances that we will receive the requisite permit from the Beijing municipal authority or from any other Chinese governmental authority. If we do not receive the requisite permit to continue to manufacture gallium arsenide substrate wafers, we may be required to cease manufacturing such wafers until we receive the requisite permit or move such manufacturing to a new location. A halt to our production of gallium arsenide substrate wafers could result in our furloughing approximately several hundred manufacturing employees. If we obtain the requisite permit after halting our production, we might not be able to recommence manufacturing gallium arsenide substrate wafers immediately because we may need to rebuild our supply chain and we may not be able to rehire our furloughed manufacturing employees. We could also lose customers to our competitors because of our inability to supply gallium arsenide substrate wafers. Any of these could materially and adversely impact our results of operations and our financial condition.
