Note 11. Commitments and Contingencies

Indemnification Agreements

We enter into standard indemnification arrangements with our customers in the ordinary course of business. Pursuant to these arrangements, we indemnify, hold harmless, and agree to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, generally their business partners or customers, in connection with any U.S. patent, or any copyright or other intellectual property infringement claim by any third party with respect to our products. The term of these indemnification agreements is generally perpetual anytime after the execution of the agreement. The maximum potential amount of future payments we could be required to make under these agreements is unlimited. We have never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, we believe the estimated fair value of these agreements is minimal.

We have entered into indemnification agreements with our directors and officers that require us to (i) 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, (ii) advance their expenses incurred as a result of any proceeding against them as to which they could be indemnified, and (iii) 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 these based on 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 months ended March 31, 2014 and 2013 (in thousands):

	Three Months Ended March 31,
	2014			2013

Beginning accrued warranty and related costs	$	1048		$	588
Accruals for warranties issued		496			264
Adjustments related to pre-existing warranties including expirations and changes in estimates		(103	)		166
Cost of warranty repair		(214	)		(269	)
Ending accrued warranty and related costs	$	1,227		$	749

Contractual Obligations

We lease certain office space, manufacturing facilities and equipment under long-term operating leases expiring at various dates through February 2023. The majority of our lease obligations relates to our lease agreement for the facility at Fremont, California with approximately 27,760 square feet, which commenced on December 1, 2008 for a term of seven years, with an option by us to cancel the lease after five years, upon forfeiture of the security deposit and payment of one-half of the fifth year's rent. On June 28, 2013, we sent a notice to terminate the lease effective November 30, 2013 with an early termination penalty of $142,000 which was recorded as an expense in the third quarter of 2013. On August 2, 2013, we signed a new lease agreement for the current facility with reduced footage of 20,767 square feet, which commenced on December 1, 2013 for a term of two years. The reduced square footage, the reduced rate per square foot, and the expected reduced operating costs, would save us approximately total $382,000 during 2014 and 2015.

We entered into a royalty agreement with a vendor 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 a total of $7.0 million royalty payment over eight years beginning in 2011 based on future royalty bearing sales. This agreement contains a clause that allows us to make a claim for credit, starting in 2013, in the event that the royalty bearing sales for the year is lower than a pre-determined amount set forth in this agreement.

Outstanding contractual obligations as of March 31, 2014 are summarized as follows (in thousands):

	Payments due by period
Contractual Obligations	Total				Less than 1 year				1-3 years				4-5 years			More than 5 years
Operating leases			$	557			$	263			$	208		$	34		$	52
Royalty agreement		3,125		3,125		1,319		800		—
Total			$	3,682			$	1,063			$	1,527		$	1,040		$	52

Purchase Obligations

In the normal course of business, we purchase or place orders for the necessary materials of our products from various suppliers and we commit to purchase products where we may incur a penalty if the agreement was canceled. As of March 31, 2014, we do not have any outstanding material purchase obligations.

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 operation.
