	The Company and Summary of Significant Accounting Policies
	The Company
	NETGEAR, Inc. (“NETGEAR” or the “Company”) was incorporated in Delaware in January 1996. The Company is a global networking company that delivers innovative products to consumers, businesses and service providers. The Company's products are built on a variety of proven technologies such as wireless, Ethernet and powerline, with a focus on reliability and ease-of-use. The product line consists of wired and wireless devices that enable networking, broadband access and network connectivity. These products are available in multiple configurations to address the needs of the end-users in each geographic region in which the Company's products are sold.
	The Company operates in three specific business segments: retail, commercial, and service provider. Each business unit is managed by a Senior Vice President/General Manager. The Company believes this structure enables it to better focus its efforts on the Company's core customer segments and allows it to be more nimble and opportunistic as a company overall. The retail business unit is focused on individual consumers and consists of high performance, dependable and easy-to-use home networking, home video monitoring, storage and digital media products. The commercial business unit is focused on small and medium size businesses and consists of business networking, storage and security solutions that bring enterprise class functionality at an affordable price. The service provider business unit is focused on the service provider market and consists of made-to-order and retail proven, whole home networking hardware and software solutions, as well as 4G LTE hotspots sold to service providers for sale to their subscribers.
	The Company sells networking products through multiple sales channels worldwide, including traditional retailers, online retailers, wholesale distributors, direct market resellers (“DMRs”), value-added resellers (“VARs”), and broadband service providers.
	Basis of presentation
	The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All inter-company accounts and transactions have been eliminated in the consolidation of these subsidiaries.
	Fiscal periods
	The Company's fiscal year begins on January 1 of the year stated and ends on December 31 of the same year. The Company reports its results on a fiscal quarter basis rather than on a calendar quarter basis. Under the fiscal quarter basis, each of the first three fiscal quarters ends on the Sunday closest to the calendar quarter end, with the fourth quarter ending on December 31.
	Use of estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates.
	Cash and cash equivalents
	The Company considers all highly liquid investments with an original maturity at the time of purchase of three months or less to be cash equivalents. The Company deposits cash and cash equivalents with high credit quality financial institutions.
	Short-term investments
	Short-term investments are partially comprised of marketable securities that consist of government securities with an original maturity or a remaining maturity at the time of purchase, of greater than three months and no more than 12 months. The marketable securities are held in the Company's name with one high quality financial institution, which acts as the Company's custodian and investment manager. These marketable securities are classified as available-for-sale securities in accordance with the provisions of the authoritative guidance for investments and are carried at fair value with unrealized gains and losses reported as a separate component of stockholders' equity.
	Short-term investments are also comprised of marketable securities related to deferred compensation under the Company’s Deferred Compensation Plan. Mutual funds are the only investments allowed in the Company's Deferred Compensation Plan and the investments are held in a grantor trust formed by the Company. The Company has classified these investments as trading securities as the grantor trust actively manages the asset allocation to match the participants’ notional fund allocations. These securities are recorded at fair market value with unrealized gains and losses included in other income (expense), net.
	Certain risks and uncertainties
	The Company's products are concentrated in the networking industry, which is characterized by rapid technological advances, changes in customer requirements and evolving regulatory requirements and industry standards. The success of the Company depends on management's ability to anticipate and/or to respond quickly and adequately to technological developments in its industry, changes in customer requirements, or changes in regulatory requirements or industry standards. Any significant delays in the development or introduction of products could have a material adverse effect on the Company's business and operating results.
	The Company relies on a limited number of third parties to manufacture all of its products. If any of the Company's third-party manufacturers cannot or will not manufacture its products in required volumes, on a cost-effective basis, in a timely manner, or at all, the Company will have to secure additional manufacturing capacity. Any interruption or delay in manufacturing could have a material adverse effect on the Company's business and operating results.
	Derivative financial instruments
	The Company uses foreign currency forward contracts to manage the exposures to foreign exchange risk related to expected future cash flows on certain forecasted revenue, costs of revenue, operating expenses, and on certain existing assets and liabilities. Foreign currency forward contracts generally mature within five months of inception. Under its foreign currency risk management strategy, the Company utilizes derivative instruments to reduce the impact of currency exchange rate movements on the Company's operating results by offsetting gains and losses on the forward contracts with increases or decreases in foreign currency transactions. The company does not use derivative financial instruments for speculative purposes.
	The Company accounts for its derivative instruments as either assets or liabilities and records them at fair value. Derivatives that are not defined as hedges in the authoritative guidance for derivatives and hedging must be adjusted to fair value through earnings. For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of cumulative other comprehensive income in stockholders' equity and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument is recognized in current earnings. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions. For derivatives designated as cash flow hedges, changes in the time value are excluded from the assessment of hedge effectiveness and are recognized in earnings.
	Concentration of credit risk
	Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents, short-term investments and accounts receivable. The Company believes that there is minimal credit risk associated with the investment of its cash and cash equivalents and short-term investments, due to the restrictions placed on the type of investment that can be entered into under the Company's investment policy. The Company's short-term investments consist of investment-grade securities, and the Company's cash and investments are held and managed by recognized financial institutions.
	The Company's customers are primarily distributors as well as retailers and broadband service providers who sell or distribute the products to a large group of end-users. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of the Company's customers to make required payments. The Company regularly performs credit evaluations of the Company's customers' financial condition and considers factors such as historical experience, credit quality, age of the accounts receivable balances, geographic or country-specific risks and current economic conditions that may affect customers' ability to pay, and, generally, requires no collateral from its customers. The Company secures credit insurance for certain customers in international and domestic markets.
	As of December 31, 2013 and 2012, Best Buy, Inc. represented 21% and 22% of the Company's total accounts receivable respectively.
	The Company is exposed to credit loss in the event of nonperformance by counterparties to the foreign currency forward contracts used to mitigate the effect of foreign currency exchange rate changes. The Company believes the counterparties for its outstanding contracts are large, financially sound institutions and thus, the Company does not anticipate nonperformance by these counterparties. However, given the recent, unprecedented turbulence in the financial markets, the failure of additional counterparties is possible.
	Fair value measurements
	The carrying amounts of the Company's financial instruments, including cash equivalents, short-term investments, accounts receivable, and accounts payable approximate their fair values due to their short maturities. Foreign currency forward contracts are recorded at fair value based on observable market data. See Note 13, Fair Value Measurements, of the Notes to Consolidated Financial Statements for disclosures regarding fair value measurements in accordance with the authoritative guidance for fair value measurements and disclosures.
	Cost method investments
	As of December 31, 2013 and December 31, 2012, the carrying value of the Company's cost method investments was $1.3 million. These investments are included in other non-current assets in the consolidated balance sheets and are carried at cost, adjusted for any impairment, because the Company does not have a controlling interest and does not have the ability to exercise significant influence over these companies. The Company monitors these investments for impairment on a quarterly basis, and adjusts carrying value for any impairment charges recognized. There were no impairments recognized in the years ended December 31, 2013 and December 31, 2012. Realized gains and losses on these investments are reported in other income (expense), net in the consolidated statements of operations. In the third fiscal quarter of 2012 the Company recognized a gain of $3.1 million on the partial sale of one of its cost method investments.
	Allowance for doubtful accounts
	The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company regularly performs credit evaluations of its customers' financial condition and considers factors such as historical experience, credit quality, age of the accounts receivable balances, and geographic or country-specific risks and economic conditions that may affect a customer's ability to pay. The allowance for doubtful accounts is reviewed quarterly and adjusted if necessary based on the Company's assessments of its customers' ability to pay. If the financial condition of the Company's customers should deteriorate or if actual defaults are higher than the Company's historical experience, additional allowances may be required, which could have an adverse impact on operating expenses.
	Inventories
	Inventories consist primarily of finished goods which are valued at the lower of cost or market, with cost being determined using the first-in, first-out method. The Company writes down its inventories based on estimated excess and obsolete inventories determined primarily by future demand forecasts. At the point of loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.
	Property and equipment, net
	Property and equipment are stated at historical cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows:
	Computer equipment	2 years
	Furniture and fixtures	5 years
	Software	2-5 years
	Machinery and equipment	2-3 years
	Leasehold improvements	Shorter of the lease term or 5 years
	Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated undiscounted future net cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. The carrying value of the asset is reviewed on a regular basis for the existence of facts, both internal and external, that may suggest impairment. Charges related to the impairment of property and equipment were not material in the years ended December 31, 2013, 2012 and 2011.
	Goodwill
	Goodwill represents the purchase price over estimated fair value of net assets of businesses acquired in a business combination. Goodwill acquired in a business combination is not amortized, but instead tested for impairment at least annually during the fourth quarter. Should certain events or indicators of impairment occur between annual impairment tests, the Company will perform the impairment test as those events or indicators occur. Examples of such events or circumstances include the following: a significant decline in the Company’s expected future cash flows; a sustained, significant decline in the Company’s stock price and market capitalization; a significant adverse change in the business climate; and slower growth rates.
	Goodwill is tested for impairment at the reporting unit level by first performing a qualitative assessment to determine whether it is more likely than not (that is, a likelihood of more than 50%) that the fair value of the reporting unit is less than its carrying value. The qualitative assessment considers the following factors: macroeconomic conditions, industry and market considerations, cost factors, overall company financial performance, events affecting the reporting units, and changes in the Company's share price. If the reporting unit does not pass the qualitative assessment, then the Company estimates its fair value and compare the fair value with the carrying value of its net assets. If the fair value is greater than the carrying value of its net assets, then no impairment results. If the fair value is less than its carrying value, then it would determine the fair value of the goodwill by comparing the implied fair value to the carrying value of the goodwill in the same manner as if the Company were being acquired in a business combination. Specifically, the Company would allocate the fair value to all of our assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that would calculate the implied fair value of goodwill. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge would be recorded to earnings in the Consolidated Statements of Operations.
	In the fourth fiscal quarter of 2013, we completed the annual impairment test of goodwill. Due to the increase in goodwill in fiscal year 2013 as a result of our acquisitions, we elected to bypass the qualitative assessment and proceed directly to estimating the fair value of net assets for each reporting unit. The fair value of the business units was determined placing an equal weighting of 50 percent on the income approach and market approach indications of value. Under the income approach, the fair value of an asset is based on the value of the estimated cash flows that the asset can be expected to generate in the future. These estimated future cash flows were discounted to arrive at their respective fair values. Under the market approach, the fair value of the unit is based on an analysis of financial data for publicly traded companies engaged in the same or similar lines of business. We compared the fair value of the reporting units to the reporting unit’s carrying value and determined that goodwill was not impaired since the estimated fair values of each of the reporting units exceeded the carrying values. The excess of fair value over carrying amount for each of our reporting units ranged from approximately 15% to approximately 219% of carrying amounts. The service provider business unit has the lowest excess of fair value over carrying amount at 15%. In order to evaluate the sensitivity of the estimated fair values of our reporting units in the goodwill impairment test, we applied a hypothetical 10% decrease to the fair values of each reporting unit. This hypothetical 10% decrease resulted in a lowest excess of fair value over carrying amount of approximately 4% for service provider business unit. We will continue to monitor goodwill on an annual basis as of the beginning of our fourth fiscal quarter and whenever events or changes in circumstances, such as significant adverse changes in business climate or operating results, changes in management's business strategy or significant declines in our stock price, indicate that there may be potential indicator of impairment.
	No goodwill impairment was recognized in the years ended December 31, 2013, 2012 or 2011.
	Intangible assets
	Purchased intangible assets with finite lives are amortized using the straight-line method over the estimated economic lives of the assets, which range from four to ten years. Finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition.
	Purchased intangible assets determined to have indefinite useful lives are not amortized. Indefinite-lived intangible assets are reviewed for impairment at least annually during the fourth quarter and whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Measurement of an impairment loss for indefinite-lived assets that management expects to hold and use is based on the fair value of the asset. Indefinite-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell. The carrying value of the asset is reviewed on a regular basis for the existence of facts, both internal and external, that may suggest impairment.
	In the fourth fiscal quarter of 2013, the Company completed the annual impairment test of indefinite-lived long-lived assets. The Company assessed whether it was more likely than not (that is, a likelihood of more than 50%) the carrying amount of its indefinite-lived intangible assets may not be recoverable from their undiscounted cash flows by considering the following factors: macroeconomic conditions, industry and market considerations, cost factors, overall company financial performance, events affecting the reporting units, and changes in our share price. Based on these factors , the Company determined that it is not more likely than not that there were events or changes in circumstances that indicated that the carrying amount of our indefinite-lived intangible assets may not be recoverable from their undiscounted cash flows, and therefore performing the first step of the two-step impairment test for each reporting unit was unnecessary. No impairments to the indefinite-lived assets were recognized resulting from the annual impairment tests in the years ended December 31, 2013, 2012 and 2011.
	In the third quarter of 2013, the Company recorded an impairment charge of $2.0 million related to the abandonment of certain IPR&D projects acquired in the AirCard acquisition. No other impairments to long-lived assets were recognized in the years ended December 31, 2013, 2012 and 2011
	Product warranties
	The Company provides for estimated future warranty obligations at the time revenue is recognized. The Company's standard warranty obligation to its direct customers generally provides for a right of return of any product for a full refund in the event that such product is not merchantable or is found to be damaged or defective. At the time revenue is recognized, an estimate of future warranty returns is recorded to reduce revenue in the amount of the expected credit or refund to be provided to its direct customers. At the time the Company records the reduction to revenue related to warranty returns, the Company includes within cost of revenue a write-down to reduce the carrying value of such products to net realizable value. The Company's standard warranty obligation to its end-users provides for replacement of a defective product for one or more years. Factors that affect the warranty obligation include product failure rates, material usage, and service delivery costs incurred in correcting product failures. The estimated cost associated with fulfilling the Company's warranty obligation to end-users is recorded in cost of revenue. Because the Company's products are manufactured by third-party manufacturers, in certain cases the Company has recourse to the third-party manufacturer for replacement or credit for the defective products. The Company gives consideration to amounts recoverable from its third-party manufacturers in determining its warranty liability. Changes in the Company's warranty liability, which is included as a component of “Other accrued liabilities” in the consolidated balance sheets, are as follows (in thousands):
		Year Ended December 31,
		2013			2012
	Balance as of beginning of the period	$	46,659		$	44,846
	Provision for warranty liability made during the period	69,755			61,985
	Settlements made during the period	(67,660		)	(60,172		)
	Balance at end of period	$	48,754		$	46,659
	Revenue recognition
	Revenue from product sales is generally recognized at the time the product is shipped provided that persuasive evidence of an arrangement exists, title and risk of loss has transferred to the customer, the selling price is fixed or determinable and collection of the related receivable is reasonably assured. Currently, for some of the Company's customers, title passes to the customer upon delivery to the port or country of destination, upon their receipt of the product, or upon the customer's resale of the product. At the end of each fiscal quarter, the Company estimates and defers revenue related to product where title has not transferred. The revenue continues to be deferred until such time that title passes to the customer. The Company assesses collectability based on a number of factors, including general economic and market conditions, past transaction history with the customer, and the creditworthiness of the customer. If the Company determines that collection of the fee is not reasonably assured, then the Company defers the fee and recognizes revenue upon receipt of payment.
The Company has an insignificant amount of product offerings with multiple elements. The Company's multiple-element product offerings include networking hardware with embedded software, various software subscription services, and support, which are considered separate units of accounting. In general, the networking hardware with embedded software is delivered up front, while the subscription services and support are delivered over the subscription and support period. The Company allocates revenue to the software deliverables and the non-software deliverables (including software deliverables which function together with hardware deliverables to provide the product's essential functionality) based upon their relative selling price. Revenue allocated to each unit of accounting is then recognized when persuasive evidence of an arrangement exists, title and risk of loss has transferred to the customer, the selling price is fixed or determinable and collection of the related receivable is reasonably assured.
When applying the relative selling price method, the Company determines the selling price for each deliverable using vendor-specific objective evidence ("VSOE") of fair value of the deliverable, or when VSOE of fair value is unavailable, its best estimate of selling price (“ESP”), as the Company has determined it is unable to establish third-party evidence of selling price for the deliverables. In determining VSOE, the Company requires that a substantial majority of the selling prices for a deliverable sold on a stand-alone basis fall within a reasonably narrow pricing range, generally evidenced by approximately 80% of such historical stand-alone transactions falling within +/-15% of the median price. The Company determines ESP for a deliverable by considering multiple factors including, but not limited to, market conditions, competitive landscape, internal costs, gross margin objectives and pricing practices. The objective of ESP is to determine the price at which the Company would transact a sale if the deliverable were sold on a stand-alone basis. The determination of ESP is made through consultation with and formal approval by the Company's management, taking into consideration the go-to-market strategy.
Certain distributors and retailers generally have the right to return product for stock rotation purposes. Upon shipment of the product, the Company reduces revenue for an estimate of potential future product warranty and stock rotation returns related to the current period product revenue. Management analyzes historical returns, channel inventory levels, current economic trends and changes in customer demand for the Company's products when evaluating the adequacy of the allowance for sales returns, namely warranty and stock rotation returns. Revenue on shipments is also reduced for estimated price protection and sales incentives deemed to be contra-revenue under the authoritative guidance for revenue recognition.
Sales incentives
The Company accrues for sales incentives as a marketing expense if it receives an identifiable benefit in exchange and can reasonably estimate the fair value of the identifiable benefit received; otherwise, it is recorded as a reduction to revenues. As a consequence, the Company records a substantial portion of its channel marketing costs as a reduction of revenue.
The Company records estimated reductions to revenues for sales incentives at the later of when the related revenue is recognized or when the program is offered to the customer or end consumer.
Shipping and handling fees and costs
The Company includes shipping and handling fees billed to customers in net revenue. Shipping and handling costs associated with inbound freight are included in cost of revenue. In cases where the Company gives a freight allowance to the customer for their own inbound freight costs, such costs are appropriately recorded as a reduction in net revenue. Shipping and handling costs associated with outbound freight are included in sales and marketing expenses and totaled $11.6 million, $12.1 million and $13.9 million in the years ended December 31, 2013, 2012 and 2011 respectively.
Research and development
Costs incurred in the research and development of new products are charged to expense as incurred.
Advertising costs
Advertising costs are expensed as incurred. Total advertising and promotional expenses were $18.0 million, $19.0 million, and $21.7 million in the years ended December 31, 2013, 2012 and 2011 respectively.
Income taxes
The Company accounts for income taxes under an asset and liability approach. Under this method, income tax expense is recognized for the amount of taxes payable or refundable for the current year. In addition, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences resulting from different treatment for tax versus accounting for certain items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities, which are included within the consolidated balance sheet. The Company must then assess the likelihood that the Company's deferred tax assets will be recovered from future taxable income and to the extent the Company believes that recovery is not more likely than not, the Company must establish a valuation allowance.
In the ordinary course of business there is inherent uncertainty in assessing the Company's income tax positions. The Company assesses its tax positions and records benefits for all years subject to examination based on management's evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, the Company records the largest amount of tax benefit with a greater than 50 percent likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recorded in the financial statements. Where applicable, associated interest and penalties have also been recognized as a component of income tax expense.
Computation of net income per share
Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the additional dilution from potential issuances of common stock, such as stock issuable pursuant to the exercise of stock options and awards. Potentially dilutive shares are excluded from the computation of diluted net income per share when their effect is anti-dilutive.
Stock-based compensation
The Company measures stock-based compensation at the grant date based on the fair value of the award. The fair value of stock options is estimated using the Black-Scholes option pricing model. Estimated compensation cost relating to restricted stock units (“RSUs”) is based on the closing fair market value of the Company’s common stock on the date of grant. The fair value of Employee Stock Purchase Plan (“ESPP”) is based on the 15% discount at purchase, since the price of the shares is determined at the purchase date.
The compensation expense for equity awards is reduced by an estimate for forfeitures and is recognized over the vesting period of the award under a graded vesting method.  In addition, the Company will recognize an excess benefit from stock-based compensation in equity based on the difference between tax expense computed with consideration of the windfall deduction and without consideration of the windfall deduction. In addition, the Company accounts for the indirect effects of stock-based compensation on the research tax credit and the foreign tax credit in the income statement. See Note 11, Employee Benefit Plans, of the Notes to Consolidated Financial Statements for a further discussion on stock-based compensation.
Comprehensive income
Comprehensive income consists of net income and other gains and losses affecting stockholder's equity that the Company excluded from net income, including gains and losses related to fair value of short-term investments and the effective portion of cash flow hedges that were outstanding as of the end of the year.
Foreign currency translation
The Company's functional currency is the U.S. dollar for all of its international subsidiaries. Foreign currency transactions of international subsidiaries are re-measured into U.S. dollars at the end-of-period exchange rates for monetary assets and liabilities, and historical exchange rates for non-monetary assets. Expenses are re-measured at average exchange rates in effect during each period, except for expenses related to non-monetary assets, which are re-measured at historical exchange rates. Revenue is re-measured at average exchange rates in effect during each period. Gains and losses arising from foreign currency transactions are included in total comprehensive income and were a net loss of $1.6 million for the year ended December 31, 2013, a net gain of $0.2 million for the year ended December 31, 2012 and a net gain of $0.1 million for the year ended December 31, 2011.
Recent accounting pronouncements
In March 2013, the FASB issued ASU 2013-05, "Foreign Currency Matters," which provides the standards for parent's accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. ASU 2013-05 is effective for reporting periods beginning after December 15, 2013. The Company will adopt this standard in the first quarter of 2014 and it does not expect the adoption to have a significant impact on its financial position, results of operations or cash flows.
In July 2013, the FASB issued ASU 2013-11, "Income Taxes," which provides explicit guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward or a tax credit carryforward exists. Under the new standard update, the Company’s unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward or a tax credit carryforward. ASU 2013-11 is effective for the Company beginning in the first quarter fiscal 2014 and applied prospectively or retroactively with early adoption permitted. The Company has adopted ASU 2013-11 during the three months ended December 31, 2013 on a prospective basis. It does not have a significant impact on the Company's financial position, results of operations or cash flows.

Business Combinations [Abstract]	'
Business Acquisitions	'
	Business Acquisitions
	Arada Systems, Inc.
	On June 21, 2013, the Company acquired certain assets and operations of Arada Systems, Inc. (“Arada”), a privately-held company that develops, licenses, and provides solutions for the next generation of uses of Wi-Fi, for total purchase consideration of $5.2 million in cash. The Company believes the acquisition will bolster its wireless product offerings in its commercial business unit and strengthen its market position in the small to medium size campus wireless LAN market. The Company paid $4.2 million of the aggregate purchase price in the second quarter of 2013, and expects to pay the remaining $1.1 million, less amounts used to satisfy certain claims, twelve months after the closing of the acquisition.
	The acquisition qualified as a business combination and was accounted for using the acquisition method of accounting. The results of Arada have been included in the consolidated financial statements since the date of acquisition. Pro forma results of operations for the acquisition are not presented as the financial impact to the Company's consolidated results of operations is not material.
	The allocation of the purchase price was as follows (in thousands):
	Property and equipment, net	$	15
	Intangible assets, net	4,040
	Goodwill	1,195
	Total purchase price	$	5,250
	The fair values for tangible and intangible assets acquired and liabilities assumed were based on estimates of their fair values as of the acquisition date. These estimates are subject to revision, which may result in adjustments to the values presented above. We expect to finalize these amounts within twelve months from the acquisition date.
	Of the $1.2 million of goodwill recorded on the acquisition of Arada, approximately $0.7 million and $1.2 million are deductible for U.S. federal and state income tax purposes, respectively. The goodwill recognized, which was assigned to the Company's commercial business unit, is primarily attributable to expected synergies resulting from the acquisition.
	The Company designated $4.0 million of the acquired intangible assets as technology. The value was calculated based on the present value of the future estimated cash flows derived from estimated savings attributable to the existing technology and discounted at 21.5%. The acquired existing technology is being amortized over its estimated useful life of five years.
	AirCard Division of Sierra Wireless, Inc.
	On April 2, 2013, the Company completed the acquisition of select assets and operations of the Sierra Wireless, Inc. AirCard business ("AirCard"), including customer relationships, a world-class LTE engineering team, certain intellectual property, inventory and property and equipment. The Company believes this acquisition will accelerate the mobile initiative of the service provider business unit to become a global leader in providing the latest in LTE data networking access devices.
	The Company paid $140.0 million of the aggregate purchase price in the second quarter of 2013. The acquisition qualified as a business combination and was accounted for using the acquisition method of accounting. The results of AirCard have been included in the consolidated financial statements since the date of acquisition. Revenue and earnings for AirCard as of the acquisition date are not presented as the business was fully integrated into the service provider business unit subsequent to the acquisition and therefore impracticable for the Company to quantify.
	The allocation of the purchase price was as follows (in thousands):
	Inventories	$	2,874
	Prepaid expenses	9,030
	Other assets	3,226
	Property and equipment, net	7,455
	Intangible assets, net	69,700
	Goodwill	53,841
	Liabilities assumed	(6,096		)
	Total purchase price	$	140,030
	In the third quarter of 2013, the Company made an adjustment of $0.5 million to goodwill related to revised inventory estimates. The fair values for tangible and intangible assets acquired and liabilities assumed are based on estimates of their fair values as of the acquisition date. These estimates are subject to revision, which may result in adjustments to the values presented above. We expect to finalize these amounts within twelve months from the acquisition date.
	Of the $53.8 million of goodwill recorded on the acquisition of AirCard, approximately $36.6 million, $2.3 million and $53.8 million is deductible for U.S. federal, Canadian, and U.S. state income tax purposes, respectively. The goodwill recognized, which was assigned to the Company's service provider business unit, is primarily attributable to expected synergies resulting from the acquisition.
	The Company designated $16.3 million of the acquired intangible assets as technology. The value was calculated based on the present value of the future estimated cash flows derived from estimated savings attributable to the existing technology and discounted at 10.0%. The acquired technology is being amortized over its estimated useful life of four years.
	The Company designated $40.5 million of the acquired intangible assets as customer relationships. The value was calculated based on the present value of the future estimated cash flows derived from projections of future operations attributable to existing customer relationships and discounted at 12.0%. The acquired customer relationships are being amortized over an estimated useful life of eight years
	The Company designated $2.3 million of the acquired intangible assets as non-compete agreements. The value was calculated based on the present value of the future estimated cash flows derived from projections of future operations attributable to the non-compete agreements and discounted at 12.0%. The acquired agreements are being amortized over an estimated useful life of five years.
	The Company designated $1.1 million of the acquired intangible assets as backlog. The value was calculated based on the present value of the future contractual revenue and discounted at 10.0%. The acquired backlog was fully amortized in the second quarter of 2013.
	The Company acquired $9.5 million in in-process research and development (“IPR&D”) projects. The value was calculated based on the present value of future estimated cash flows discounted at 13.0%, derived from projections of future revenues attributable to the assets, expected economic life of the assets, and royalty rates. The IPR&D acquired is considered indefinite lived intangible assets until research and development efforts associated with the projects are completed or abandoned. The most significant of the acquired IPR&D projects relate to multimode LTE technologies, Mobile Hot Spot, USB dongle, and Module form factors. As of December 31, 2013, $7.4 million of the acquired IPR&D has reached technical feasibility and was reclassified to definite-lived intangibles and with an estimated useful life of four years. In addition, the Company recorded an impairment charge of $2.0 million in the third quarter of 2013, related to the abandonment of certain IPR&D projects acquired. The Company expects to complete the remaining $0.1 million in IPR&D projects, at an estimated cost of $0.2 million, by the second quarter of 2014.
	Pro forma financial information
	The unaudited pro forma financial information in the table below summarizes the combined results of our operations and those of AirCard for the periods shown as though the acquisition of AirCard occurred as of the beginning of the fiscal year 2012. The pro forma financial information for the periods presented includes the accounting effects of the business combination, including adjustments to the amortization of intangible assets, fair value of acquired inventory, acquisition-related costs, integration expenses and related tax effects of these adjustments, where applicable. This information is for informational purposes only, is subject to a number of estimates, assumptions and other uncertainties, and may not be indicative of the results of operations that would have been achieved if the acquisition had taken place at January 1, 2012.
	The unaudited pro forma financial information is as follows (in thousands):

	AVAAK, Inc.
	On July 2, 2012, the Company acquired 100% of the voting equity interests of AVAAK, Inc. (“AVAAK”), a privately-held company that developed wire-free video networking products for total purchase consideration of $24.0 million in cash. The Company believes the acquisition will bolster its retail business unit product offerings and expand its presence into the smart home market. The Company paid $21.6 million of the aggregate purchase price in the third quarter of 2012, and the remaining $2.4 million was paid in the third quarter of 2013.
	The acquisition qualified as a business combination and was accounted for using the acquisition method of accounting. The results of AVAAK have been included in the consolidated financial statements since the date of acquisition. Pro forma results of operations for the acquisition are not presented as the financial impact to the Company's consolidated results of operations is not material.
	The allocation of the purchase price was as follows (in thousands):
	Net tangible assets acquired	$	172
	Deferred tax assets, net	5,937
	Intangible assets, net	6,000
	Goodwill	11,895
	Total consideration	$	24,004
	None of the goodwill recognized related to AVAAK is deductible for income tax purposes. The goodwill recognized, which was assigned to the Company's retail business unit, is primarily attributable to expected synergies resulting from the acquisition.
	In connection with the acquisition, the Company recorded $5.9 million of deferred tax assets net of deferred tax liabilities. The deferred tax assets arise from the tax benefit of the estimated net operating losses as of the date of the acquisition after consideration of limitations on the use under U.S. Internal Revenue Code section 382. The deferred tax assets are reduced by deferred tax liabilities recorded for the book basis in intangible assets and in-process research and development ("IPR&D") for which the Company has no tax basis.
	The Company designated $2.3 million of the acquired intangible assets as technology. The value was calculated based on the present value of the future estimated cash flows derived from estimated savings attributable to the existing technology and discounted at 14.0%. The acquired existing technology is being amortized over its estimated useful life of five years.
	The Company designated $0.3 million of the acquired intangible assets as customer relationships. The value was calculated based on the present value of the future estimated cash flows derived from projections of future operations attributable to existing customer relationships and discounted at 14.0%. The acquired customer relationships are being amortized over an estimated useful life of five years.
	The Company designated $1.4 million of the acquired intangible assets as trade name and trademarks. The value was calculated based on the present value of the future estimated cash flows derived from projections of future operations attributable to existing trade name and trademarks and discounted at 16.0%. The acquired trade name and trademarks are being amortized over an estimated useful life of five years.
	In addition, $2.0 million of the consideration paid represents the fair value of acquired IPR&D projects. The IPR&D acquired is considered indefinite lived intangible assets until research and development efforts associated with the projects are completed or abandoned. The most significant of the acquired IPR&D projects relate to camera technology and applications. As of the first fiscal quarter of 2013, all of the acquired IPR&D had reached technical feasibility and was reclassified to definite intangibles with an estimated useful life of four years.
	Firetide, Inc.
	On June 4, 2012, the Company acquired certain intellectual property of Firetide, Inc. (“Firetide”) for an aggregate purchase price of $7.2 million in cash. The acquisition included intangible assets that existed at the closing date, including IP contracts, technology assets, business technology, and goodwill. The Company believes the acquisition will bolster its wireless product offerings in its commercial business unit and strengthen its market position in the small to medium size campus wireless LAN market.
	The acquisition qualified as a business combination and was accounted for using the acquisition method of accounting. The results of Firetide have been included in the consolidated financial statements since the date of acquisition. Pro forma results of operations for the acquisition are not presented as the financial impact to the Company's consolidated results of operations is not material.
	The Company paid $6.6 million of the aggregate purchase price in the second quarter of 2012, and the remaining $0.6 million was paid in the second fiscal quarter of 2013. The ongoing costs of developing these assets subsequent to the date of acquisition have been included in the consolidated financial statements since the date of acquisition. The historical results of operations related to the acquired assets prior to the acquisition were not material to the Company’s results of operations.
	The allocation of the purchase price was as follows (in thousands):
	Intangible assets, net	$	4,159
	Goodwill	3,041
	Total consideration	$	7,200
Of the $3.0 million of goodwill recorded on the acquisition of Firetide, approximately $1.6 million and $3.0 million is deductible for U.S. federal and state income tax purposes, respectively. The goodwill recognized, which was assigned to the Company's commercial business unit, is primarily attributable to expected synergies and the assembled workforce of Firetide.
The Company designated the $4.2 million in acquired intangible assets as technology. The value was calculated based on the present value of the future estimated cash flows derived from estimated savings attributable to the existing technology and discounted at 22.0%. The acquired existing technology is being amortized over its estimated useful life of five years.

	The Company’s marketable securities are classified as available-for-sale consisting of government securities and trading securities consisting of mutual funds. All the securities are with an original maturity or remaining maturity at the time of purchase of greater than three months and no more than 12 months. Accordingly, none of the short-term investments have unrealized losses greater than 12 months.
	Cost Method Investments
	As of December 31, 2013 and December 31, 2012, the carrying value of the Company's cost method investments was $1.3 million. These investments are included in other non-current assets in the consolidated balance sheets and are carried at cost, adjusted for any impairment, because the Company does not have a controlling interest and does not have the ability to exercise significant influence over these companies. The Company monitors these investments for impairment on a quarterly basis, and adjusts carrying value for any impairment charges recognized. There were no impairments recognized in the years ended December 31, 2013 and December 31, 2012. Realized gains and losses on these investments are reported in other income (expense), net in the consolidated statements of operations. In the third fiscal quarter of 2012 the Company recognized a gain of $3.1 million on the partial sale of one of its cost method investments. No other gains or losses were recorded in the years ended December 31, 2013 and December 31, 2012.

	The Company purchased finite-lived intangible assets of $64.2 million and indefinite-lived assets of $9.5 million, as a result of its acquisition of AirCard and Arada during the second quarter of 2013. For further discussion regarding the AirCard and Arada acquisitions, see Note 2, Business Acquisitions. In addition, the Company purchased $0.3 million in patents during the second quarter of 2013.
As of December 31, 2013, the Company had $0.1 million in indefinite-lived intangible assets. This balance relates to the remaining IPR&D assets acquired in connection with the Company's acquisition of AirCard. IPR&D assets represent IPR&D projects that have not reached technical feasibility and are required to be classified as indefinite-lived assets until the successful completion or abandonment of the associated research and development efforts. Accordingly, during the development period after the date of acquisition, these assets will not be amortized. When the asset reaches technical feasibility, the Company will determine the useful life of the asset, reclassify the asset out of IPR&D, and begin amortization. Development costs incurred after acquisition on acquired IPR&D projects are expensed as incurred. As of December 31, 2013, $7.4 million of the IPR&D had reached technical feasibility and as a result, was reclassified from IPR&D to technology. In addition, $2.0 million of IPR&D projects were abandoned during the third quarter of 2013. The Company expects to complete the remaining IPR&D by the second quarter of 2014, for an estimated future cost to complete of $0.2 million.
Amortization of purchased intangible assets in the years ended December 31, 2013, 2012 and 2011 was $15.5 million, $4.9 million and $4.8 million, respectively. In the year ended December 31, 2013, the Company recorded an impairment charge of $2.0 million due to the abandonment of IPR&D discussed above. No impairment charges were recorded in the years ended December 31, 2012 and 2011.
Estimated amortization expense related to finite-lived intangibles for each of the next five years and thereafter is as follows:

Derivative Financial Instruments	'
	Derivative Financial Instruments
	The Company’s subsidiaries have had, and will continue to have material future cash flows, including revenue and expenses, which are denominated in currencies other than the Company’s functional currency. The Company and all its subsidiaries designate the U.S. dollar as the functional currency. Changes in exchange rates between the Company’s functional currency and other currencies in which the Company transacts business will cause fluctuations in cash flow expectations and cash flow realized or settled. Accordingly, the Company uses derivatives to mitigate its business exposure to foreign exchange risk. The Company enters into foreign currency forward contracts in Australian dollars, British pounds, Euros, and Japanese yen to manage the exposures to foreign exchange risk related to expected future cash flows on certain forecasted revenue, costs of revenue, operating expenses and existing assets and liabilities. The Company does not enter into derivatives transactions for trading or speculative purposes.
	The Company’s foreign currency forward contracts do not contain any credit-risk-related contingent features. The Company is exposed to credit losses in the event of nonperformance by the counter-parties of its forward contracts. The Company enters into derivative contracts with high-quality financial institutions and limits the amount of credit exposure to any one counter-party. In addition, the derivative contracts typically mature in less than six months and the Company continuously evaluates the credit standing of its counter-party financial institutions. The counter-parties to these arrangements are large highly rated financial institutions and the Company does not consider non-performance a material risk.
	The Company may choose not to hedge certain foreign exchange exposures for a variety of reasons, including, but not limited to, immateriality, accounting considerations and the prohibitive economic cost of hedging particular exposures. There can be no assurance the hedges will offset more than a portion of the financial impact resulting from movements in foreign exchange rates. The Company’s accounting policies for these instruments are based on whether the instruments are designated as hedge or non-hedge instruments in accordance with the authoritative guidance for derivatives and hedging. The Company records all derivatives on the balance sheet at fair value. The effective portions of cash flow hedges are recorded in other comprehensive income until the hedged item is recognized in earnings. Derivatives that are not designated as hedging instruments and the ineffective portions of its designated hedges are adjusted to fair value through earnings in other income (expense), net in the consolidated statement of operations.
	The fair values of the Company’s derivative instruments and the line items on the consolidated balance sheet to which they were recorded as of December 31, 2013, and December 31, 2012, are summarized as follows (in thousands):

	Offsetting Derivative Assets and Liabilities
	The Company has entered into master netting arrangements which allow net settlements under certain conditions. Although netting is permitted, it is currently the Company's policy and practice to record all derivative assets and liabilities on a gross basis in the condensed consolidated balance sheets.

	Cash flow hedges
	To help manage the exposure of operating margins to fluctuations in foreign currency exchange rates, the Company hedges a portion of its anticipated foreign currency revenue, costs of revenue and certain operating expenses. These hedges are designated at the inception of the hedge relationship as cash flow hedges under the authoritative guidance for derivatives and hedging. Effectiveness is tested at least quarterly both prospectively and retrospectively using regression analysis to ensure that the hedge relationship has been effective and is likely to remain effective in the future. The Company typically hedges portions of its anticipated foreign currency exposure for three to five months. The Company enters into about five forward contracts per quarter with an average size of about $7 million USD equivalent related to its cash flow hedging program.
	The Company expects to reclassify to earnings all of the amounts recorded in other comprehensive income ("OCI") associated with its cash flow hedges over the next 12 months. OCI associated with cash flow hedges of foreign currency revenue is recognized as a component of net revenue in the same period as the related revenue is recognized. OCI associated with cash flow hedges of foreign currency costs of revenue and operating expenses are recognized as a component of cost of revenue and operating expense in the same period as the related costs of revenue and operating expenses are recognized.
	Derivative instruments designated as cash flow hedges must be de-designated as hedges when it is probable the forecasted hedged transaction will not occur within the designated hedge period or if not recognized within 60 days following the end of the hedge period. Deferred gains and losses in other comprehensive income associated with such derivative instruments are reclassified immediately into earnings through other income and expense. Any subsequent changes in fair value of such derivative instruments also are reflected in current earnings unless they are re-designated as hedges of other transactions. The Company did not recognize any material net gains or losses related to the loss of hedge designation on discontinued cash flow hedges during the years ended December 31, 2013, 2012 and 2011.
	The effects of the Company’s derivative instruments on OCI and the consolidated statement of operations for the years ended December 31, 2013, 2012 and 2011 are summarized as follows (in thousands):

The Company did not recognize any net gain or loss related to the ineffective portion of cash flow hedges during the years ended December 31, 2013, 2012 and 2011.
Non-designated hedges
The Company enters into non-designated hedges under the authoritative guidance for derivatives and hedging to manage the exposure of non-functional currency monetary assets and liabilities held on its financial statements to fluctuations in foreign currency exchange rates, as well as to reduce volatility in other income and expense. The non-designated hedges are generally expected to offset the changes in value of its net non-functional currency asset and liability position resulting from foreign exchange rate fluctuations. Foreign currency denominated accounts receivable and payable are hedged with non-designated hedges when the related anticipated foreign revenue and expenses are recognized in the Company’s financial statements. The Company also hedges certain non-functional currency monetary assets and liabilities that may not be incorporated into the cash flow hedge program. The Company adjusts its non-designated hedges monthly and enters into about 13 non-designated derivatives per quarter. The average size of its non-designated hedges is about $2 million USD equivalent and these hedges normally range from one to five months in duration.
The effects of the Company’s derivatives not designated as hedging instruments in other income (expense), net in the consolidated statements of operations for the years ended December 31, 2013 and 2012, are as follows (in thousands):

	Net Income Per Share
	Basic net income per share is computed by dividing the net income for the period by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing the net income for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding during the period. Potentially dilutive common shares include outstanding stock options and unvested restricted stock awards, which are reflected in diluted net income per share by application of the treasury stock method. Under the treasury stock method, the amount that the employee must pay for exercising stock options, the amount of stock-based compensation cost for future services that the Company has not yet recognized, and the estimated tax benefit that would be recorded in additional paid-in capital upon exercise are assumed to be used to repurchase shares.

	Income tax benefits in the amount of $0.4 million, $1.1 million and $3.5 million related to stock options were credited to additional paid-in capital during the years ended December 31, 2013, 2012, and 2011, respectively. As a result of changes in fair value of available for sale securities, income tax benefit of $16,000, tax expense of $5,000 and $8,000 was recorded in comprehensive income related to the years ended December 31, 2013, 2012, and 2011, respectively.
	As of December 31, 2013, the Company has approximately $20.2 million and $0.1 million of acquired federal and state net operating loss carry forwards as well as $0.7 million of California tax credits carryforwards. All of these losses and $0.1 million of these credits are subject to annual usage limitations under Internal Revenue Code Section 382. The federal losses expire in different years beginning in fiscal 2021. The state loss begins to expire in fiscal 2015. The state tax credit carryforwards have no expiration.
	The Company files income tax returns in the U.S. federal jurisdiction and various state, local, and foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state, local, or foreign income tax examinations for years before 2008. In 2011, the US federal Internal Revenue Service (IRS) commenced an audit of the Company's 2008 and 2009 tax years. The audit was completed in October 2012, and all issues under examination by the IRS were effectively settled. In November, 2012, the Italian Tax Authority (ITA) commenced an audit of the Company’s 2004 through 2011 tax years, and has subsequently extended audit procedures to include the 2012 tax year. The Company has limited audit activity in various states and other foreign jurisdictions. Due to the uncertain nature of ongoing tax audits, the Company has recorded its liability for uncertain tax positions as part of its long-term liability as payments cannot be anticipated over the next 12 months. The existing tax positions of the Company continue to generate an increase in the liability for uncertain tax positions. The liability for uncertain tax positions may be reduced for liabilities that are settled with taxing authorities or on which the statute of limitations could expire without assessment from tax authorities. The possible reduction in liabilities for uncertain tax positions resulting from the expiration of statutes of limitation in multiple jurisdictions in the next 12 months is approximately $2.8 million, excluding the interest, penalties and the effect of any related deferred tax assets or liabilities.
	A reconciliation of the beginning and ending amount of gross unrecognized tax benefits (“UTB”) is as follows (in thousands):
		Federal, State, and Foreign Tax
	Gross UTB Balance at December 31, 2010	$	18,432
	Additions based on tax positions related to the current year	1,795
	Additions for tax positions of prior years	1,015
	Settlements	(179		)
	Reductions for tax positions of prior years	(2		)

Reductions for tax positions of prior years	(1,163		)
Reductions due to lapse of applicable statutes	(1,314		)
Adjustments due to foreign exchange rate movement	43
Gross UTB Balance at December 31, 2013	$	12,743
The total amount of net UTB that, if recognized would affect the effective tax rate as of December 31, 2013 is $11.8 million. The ending net UTB results from adjusting the gross balance at December 31, 2013 for items such as U.S. federal and state deferred tax, foreign tax credits, interest, and deductible taxes. The net UTB is included as a component of non-current income taxes payable within the consolidated balance sheet.
The Company recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the years ended December 31, 2013, 2012, and 2011, total interest and penalties expensed were $446,000, $74,000 and $30,000, respectively. As of December 31, 2013 and December 31, 2012, accrued interest and penalties on a gross basis was $2.1 million and $1.8 million, respectively. Included in accrued interest are amounts related to tax positions for which the ultimate deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Because of the impact of deferred tax accounting, other than interest, the impact of any uncertain tax benefits related to temporary differences would not affect the annual effective tax rate but would accelerate the payment of cash to the taxing authority to an earlier period.
With the exception of those foreign sales subsidiaries for which deferred tax has been provided, the Company intends to indefinitely reinvest foreign earnings. These earnings were approximately $60.5 million and $63.4 million as of December 31, 2013 and December 31, 2012, respectively. Because of the availability of U.S. foreign tax credits, it is not practicable to determine the income tax liability that would be payable if such earnings were not indefinitely reinvested.

	Commitments and Contingencies
	Leases
	The Company leases office space, cars and equipment under non-cancelable operating leases with various expiration dates through December 2026. Rent expense in the years ended, December 31, 2013, 2012, and 2011 was $9.9 million, $7.6 million and $7.0 million, respectively. The terms of some of the Company’s office leases provide for rental payments on a graduated scale. The Company recognizes rent expense on a straight-line basis over the lease period, and has accrued for rent expense incurred but not paid.
	Future minimum lease payments under non-cancelable operating leases are as follows (in thousands):
	Year Ending December 31,
	2014	$	2,987
	2015	9,242
	2016	6,005
	2017	5,028
	2018	4,697
	Thereafter	5,990
	Total minimum lease payments	$	33,949
	Employment Agreements
	The Company has signed various employment agreements with key executives pursuant to which, if their employment is terminated without cause, such employees are entitled to receive their base salary (and commission or bonus, as applicable) for 52 weeks (for the Chief Executive Officer), 39 weeks (for the Senior Vice President of Worldwide Operations and Support) and up to 26 weeks (for other key executives). Such employees will also continue to have stock options vest for up to a one-year period following such termination without cause. If a termination without cause or resignation for good reason occurs within one year of a change in control, such employees are entitled to full acceleration (for the Chief Executive Officer) and up to two years acceleration (for other key executives) of any unvested portion of his or her equity awards.
	Purchase Obligations
	The Company has entered into various inventory-related purchase agreements with suppliers. Generally, under these agreements, 50% of orders are cancelable by giving notice 46 to 60 days prior to the expected shipment date and 25% of orders are cancelable by giving notice 31 to 45 days prior to the expected shipment date. Orders are non-cancelable within 30 days prior to the expected shipment date. At December 31, 2013, the Company had $187.3 million in non-cancelable purchase commitments with suppliers. The Company establishes a loss liability for all products it does not expect to sell for which it has committed purchases from suppliers. Such losses have not been material to date.
	Guarantees and Indemnifications
	The Company, as permitted under Delaware law and in accordance with its Bylaws, indemnifies its officers and directors for certain events or occurrences, subject to certain limits, while the officer or director is or was serving at the Company’s request in such capacity. The term of the indemnification period is for the officer’s or director’s lifetime. The maximum amount of potential future indemnification is unlimited; however, the Company has a Director and Officer Insurance Policy that limits its exposure and enables it to recover a portion of any future amounts paid. As a result of its insurance policy coverage, the Company believes the fair value of these indemnification agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of December 31, 2013.
	In its sales agreements, the Company typically agrees to indemnify its direct customers, distributors and resellers for any expenses or liability resulting from claimed infringements of patents, trademarks or copyrights of third parties. The terms of these indemnification agreements are generally perpetual any time after execution of the agreement. The maximum amount of potential future indemnification is unlimited. The Company believes the estimated fair value of these agreements is minimal. Accordingly, the Company has no liabilities recorded for these agreements as of December 31, 2013.
	Litigation and Other Legal Matters
	The Company is involved in disputes, litigation, and other legal actions, including, but not limited to, the matters described below. In all cases, at each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. In such cases, the Company accrues for the amount, or if a range, the Company accrues the low end of the range as a component of legal expense in litigation reserves. The Company monitors developments in these legal matters that could affect the estimate the Company had previously accrued. In relation to such matters, the Company currently believes that there are no existing claims or proceedings that are likely to have a material adverse effect on its financial position within the next twelve months, or the outcome of these matters is currently not determinable. There are many uncertainties associated with any litigation, and these actions or other third-party claims against the Company may cause the Company to incur costly litigation and/or substantial settlement charges. In addition, the resolution of any intellectual property litigation may require the Company to make royalty payments, which could have an adverse effect in future periods. If any of those events were to occur, the Company's business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from the Company's estimates, which could result in the need to adjust the liability and record additional expenses.
	Ruckus Wireless v. NETGEAR Inc.
	On May 5, 2008, a lawsuit was filed against the Company by Ruckus Wireless (“Ruckus”), a developer of Wi-Fi technology, in the U.S. District Court, Northern District of California (case number C08-2310-PJH (“NETGEAR I”)). Ruckus alleges that the Company infringes U.S. Patent Nos. 7,358,912 ("the '912 Patent") and 7,193,562 ("the '562 Patent") in the course of deploying Wi-Fi antenna array technology in its WPN824 RangeMax wireless router. Ruckus also sued Rayspan Corporation alleging similar claims of patent infringement. The Company filed its answer to the lawsuit in the third quarter of 2008. The Company and Rayspan Corporation jointly filed a request for inter partes reexamination of the Ruckus patents with the USPTO on September 4, 2008. The Court issued a stay of the litigation while the reexaminations proceeded in the USPTO. On November 28, 2008, a reexamination was ordered with respect to claims 11-17 of the '562 Patent, but denied with respect to claims 1-10 and 18-36. On December 17, 2008, the defendants jointly filed a petition to challenge the denial of reexamination of claims 1-10 and 18-36 of the '562 Patent. In July 2009, the petition was denied, and the remaining claims 11-17 were confirmed by the USPTO. On December 2, 2008, reexamination was granted with regard to the '912 Patent. In early October 2009, the Company received an Action Closing Prosecution in the reexamination of the '912 Patent. All the claims of the '912 Patent, with the exception of the unchallenged claims 7 and 8, were finally rejected by the USPTO. On October 30, 2009, Ruckus submitted an “after-final” amendment in the '912 Patent reexamination proceeding. The Company's comments to Ruckus' “after-final” amendment were submitted on November 30, 2009. On December 1, 2009, the Court found that bifurcating the '562 Patent from the '912 Patent and commencing litigation on the '562 Patent while the USPTO reexamination process and appeals are still pending would be an inefficient use of the Court's resources. Accordingly, the Court ruled that the litigation stay should remain in effect. On September 12, 2010, the Company filed the rebuttal brief in its appeals of the USPTO's rulings during the reexamination of the '562 Patent, and the Company requested an oral hearing with the Board of Appeals at the USPTO to discuss this brief. On September 13, 2010, Ruckus filed a notice of appeal of the '912 Patent to appeal the adverse rulings it received from the USPTO in the reexamination of this patent. The Company filed a respondent's brief in the '912 Patent case on January 24, 2011. An oral hearing in the '562 case was set for February 1, 2011, but the Company decided to cancel it and let the USPTO decide the '562 case based solely on the previously submitted papers. On May 13, 2011, the USPTO indicated that the Company was successful in its appeal of the examiner's previous decision to allow claims 11-17 in the '562 reexamination, and the USPTO Board of Appeals reversed the examiner's decision and declared those claims invalid. On June 13, 2011, Ruckus submitted a request for rehearing by the Board of Appeals of its decision to reject claims 11-17 of the '562 Patent. On September 28, 2011, the Board of Patent Appeals and Interferences denied Ruckus's request for a rehearing in the '562 Patent reexamination case. Ruckus did not timely file a notice of appeal to the Court of Appeals for the Federal Circuit appealing the USPTO's cancellation of claims 11-17 of the '562 patent. Therefore, a reexamination certificate will issue with claims 11-17 cancelled and claims 1-10 and 18-36 confirmed.
	On November 4, 2009, Ruckus filed a complaint in the U.S. District Court, Northern District of California (case number C09-5271-PJH (“NETGEAR II”)), alleging the Company and Rayspan Corporation infringed a patent that is related to the patents previously asserted against the Company and Rayspan Corporation by Ruckus, as discussed above. The asserted patent in the second case was U.S. Patent No. 7,525,486 entitled “Increased wireless coverage patterns.” As with the previous Ruckus action, the WPN824 RangeMax wireless router was the alleged infringing device. The Company challenged the sufficiency of Ruckus's complaint and moved to dismiss the complaint. Ruckus opposed this motion. The Court partially agreed with the Company's motion and ordered Ruckus to submit a new complaint, which Ruckus did. The initial case management conference occurred on February 11, 2010. On March 25, 2010, the Court ordered a stay until the completion of the reexamination proceedings instigated on the patents in NETGEAR I.
	Ruckus and the Company in December 2012 requested that the stay of the California actions be lifted. This request to lift the stay was predicated on Ruckus's Withdrawal of Appeal and Cancellation of Claims ("Withdrawal") of the '912 Patent that was on appeal in re-examination at the USPTO and that was asserted by Ruckus in NETGEAR I. Through the filing of the Withdrawal, Ruckus announced its intent to withdraw and its actual withdrawal of its appeal of claims 1, 4-9-14, 18, 19, and 22-29 in re-examination (the "Appealed Claims"), and Ruckus further announced its intent to cancel and its actual cancellation of claims 30-31 in re-examination (the "Cancelled Claims"). Claims 2, 3, 15-17, 20, and 21 had previously been cancelled during re-examination (the "Previously Cancelled Claims"). Because the Appealed Claims and the Cancelled Claims represented the entirety of the claims remaining for consideration in re-examination, and the Previously Cancelled Claims are no longer of record in the offensive case by Ruckus against the Company, there are no remaining claims for re-examination in the '912 Patent and the '912 Patent cannot be asserted against the Company. Thus, the Company and Ruckus requested that the Court lift the stay of this litigation and calendar a case management conference. The case management conference occurred on January 3, 2013. At that time, the Court scheduled a claim construction hearing for August 2013. The parties to the lawsuit - the Company, Rayspan, and Ruckus - also agreed that Ruckus's two offensive cases against the Company and Rayspan should be consolidated because the cases involve similar complaints and common questions of law and fact and doing so would advance the interests of judicial economy.
	Ruckus served its infringement contentions on the Company on January 17, 2013, and the Company's invalidity contentions were served on Ruckus on March 4, 2013. On March 5, 2013, Ruckus and Rayspan filed a stipulation with proposed order dismissing Rayspan from the case, and, on March 6, 2013, the Court dismissed with prejudice Rayspan. On March 14, 2013, Ruckus filed its Second Amended Complaint, as ordered by the Court. Ruckus did not add any patents, but attempted to add claims of breach of contract and misappropriation of trade secrets by the Company. The Company believed that Ruckus contravened the Court's order that there should not be a “substantial change” in the Second Amended Complaint by adding the breach of contract and misappropriation of trade secrets claims to the lawsuit. Consequently, the Company filed a Motion to Strike the newly added claims. On May 22, 2013, the Court granted the Company's motion to strike the state law claims of trade secret misappropriation and breach of contract from the Second Amended Complaint. On June 10, 2013, Ruckus filed its Motion for Leave to Amend and File its Third Amended Complaint, adding back the trade secret misappropriation and breach of contract claim. The Company responded on June 24, 2013, and the parties orally argued the motion and response on July 24, 2013. On July 29, 2013, the Court denied Ruckus's Motion for Leave to Amend and File its Third Amended Complaint, meaning the Court would not allow Ruckus to bring its breach of contract claims or trade secret misappropriation claims because they were time barred.
	In May 2013, the parties filed their Joint Claim Construction Statement where the parties indicated to the Court the disputed claim language, the parties' competing constructions, and the evidence in support of the parties' positions. Ruckus then filed its opening claim construction brief on June 18, 2013 and the Company filed its reply on July 1, 2013. The parties gave a claim construction tutorial to the Court on August 16, 2013, and, on August 28, 2013, the parties argued their proposed claim constructions before the Court. On December 16, 2013, the Court denied Ruckus’s attempt to strike the Company’s invalidity arguments and issued its claim construction order. On January 31, 2014, the Company and Ruckus entered into a settlement agreement that settled all outstanding litigation between the parties thereby concluding this litigation.
	On November 19, 2010, the Company filed suit against Ruckus in the U.S. District Court, District of Delaware for infringement of four of the Company's patents. The Company alleged that Ruckus's manufacture, use, sale or offers for sale within the United States or importation into the United States of products, including wireless communication products, infringed United States Patent Nos. 5,812,531, 6,621,454, 7,263,143, and 5,507,035, all owned by the Company. The Company granted Ruckus an extension to file its answer to the Company's suit, and on January 11, 2011, Ruckus filed a motion to dismiss the Company's suit based on insufficient pleadings. The Company filed its response to Ruckus's motion on January 31, 2011. In addition, on May 6, 2011, Ruckus filed a motion to transfer venue to the Northern District of California. The Court denied Ruckus' motion to transfer the case to the Northern District of California and granted the Company leave to file an amended complaint rather than address the Ruckus motion to dismiss based on insufficient pleadings. The Company filed the proposed amended complaint. Nevertheless, Ruckus filed a second motion to dismiss based on insufficient pleadings by the Company. On March 28, 2012, the Delaware District Court in a memorandum opinion and order denied Ruckus's second motion to dismiss. A scheduling conference occurred April 18, 2012, and the Company submitted its initial disclosures in the case on May 15, 2012. On May 31, 2012, Ruckus filed its third motion to dismiss, asserting that the Company cannot sustain its indirect infringement and willfulness allegations without pleading pre-suit knowledge of the patents. The Company responded to Ruckus's motion to dismiss on June 18, 2012. The Court released the schedule for the case on June 8, 2012 with Claim Construction and Summary Judgment Hearings scheduled for August 9, 2013 and a ten day jury trial scheduled for October 21, 2013. On July 13, 2012, the Company added to its complaint against Ruckus an allegation of infringement of patent number 6,512,480 (“System and method for narrow beam antenna diversity in an RF data transmission system”) by Ruckus's ZoneFlex and MediaFlex products. The Company and Ruckus participated in a court-ordered mediation on September 13, 2012 in Delaware, and the parties did not come to an agreement to settle the litigation pending between the parties. Fact discovery closed on December 14, 2012 and expert discovery also closed. In addition, all claim construction and summary judgment briefing was finished. On August 9, 2013 the parties argued their claim construction and summary judgment briefing before the Court. On September 30, 2013, the Court dismissed the asserted claims of three of the Company’s five patents in suit because the Court agreed with Ruckus’s summary judgment motions that the claims were indefinite. The Court also released its claim construction rulings the same day. As a result of the Court’s rulings, two patents (6,631,454 and 7,263,143) and five claims remained standing against Ruckus for the trial that began on October 22, 2013 and ended on October 31, 2013. At the conclusion of the trial, a jury rendered a verdict that the two patent and five claims were not infringed by Ruckus, as the Company had contended, and that the patents were not invalid, as Ruckus has contended. On January 31, 2014, the Company and Ruckus entered into a settlement agreement that settled all outstanding litigation between the parties thereby concluding this litigation.
	On June 19, 2013, Ruckus filed a complaint in Delaware accusing NETGEAR of infringing United States Patent No. 8,031,129 (“the '129 Patent”) and United States Patent No. 8,150,470 (“the '470 Patent”). Ruckus accused the Company of infringing the '129 Patent by making, using, offering to sell, selling, and/or importing products, such as the Company's N600 Wireless Dual Band Routers (WNDR3400). Ruckus also accused the Company of knowingly and actively inducing infringement of the '129 Patent. Ruckus accused the Company of infringing the '470 Patent by making, using, offering to sell, selling, and/or importing products, such as NETGEAR's N600 Wireless Dual Band Gigabit Routers (WNDR3800). Ruckus also accused the Company of knowingly and actively inducing infringement of the '470 Patent. On August 26, 2013, Ruckus filed an amended complaint that dropped its claims of induced and willful infringement that were in the original complaint. The Company filed its answer to Ruckus’s complaint on October 15, 2013, and asserted that Ruckus’s patents were invalid and not infringed by the Company. On January 31, 2014, the Company and Ruckus entered into a settlement agreement that settled all outstanding litigation between the parties thereby concluding this litigation.
	The settlement did not have a material financial impact to the Company.
	Northpeak Wireless, LLC v. NETGEAR, Inc.
	In October 2008, a lawsuit was filed against the Company and 30 other companies by Northpeak Wireless, LLC (“Northpeak”) in the U.S. District Court, Northern District of Alabama. Northpeak alleges that the Company's 802.11b compatible products infringe certain claims of U.S. Patent Nos. 4,977,577 ("the '577 Patent") and 5,987,058 ("the '058 Patent"). The Company filed its answer to the lawsuit in the fourth quarter of 2008. On January 21, 2009, the District Court granted a motion to transfer the case to the U.S. District Court, Northern District of California. In August 2009, the parties stipulated to a litigation stay pending a reexamination request to the USPTO on the asserted patents. The reexaminations of the patents are proceeding. In March 2011, the USPTO confirmed the validity of the asserted claims of the '577 Patent over certain prior art references. In April 2011, the USPTO issued a final office action rejecting both asserted claims of the '058 Patent as being obvious in light of the prior art. In March 2013, the Board of Patent Appeals and Interferences of the USPTO affirmed the rejection of both asserted claims of the '058 Patent. The case remains stayed by stipulation, and no trial date has been set. The Company does not expect there to be a material financial impact to the Company because of this litigation matter.
	Ericsson v. NETGEAR, Inc.
	On September 14, 2010, Ericsson Inc. and Telefonaktiebolaget LM Ericsson (collectively “Ericsson”) filed a patent infringement lawsuit against the Company and defendants D-Link Corporation, D-Link Systems, Inc., Acer, Inc., Acer America Corporation, and Gateway, Inc. in the U.S. District Court, Eastern District of Texas alleging that the defendants infringe certain Ericsson patents. The Company has been accused of infringing eight U.S. patents: 5,790,516; 6,330,435; 6,424,625; 6,519,223; 6,772,215; 5,987,019; 6,466,568; and 5,771,468 ("the '468 Patent"). Ericsson generally alleges that the Company and the other defendants have infringed and continue to infringe the Ericsson patents through the defendants' IEEE 802.11-compliant products. In addition, Ericsson alleged that the Company infringed the claimed methods and apparatuses of the '468 Patent through the Company's PCMCIA routers. The Company filed its answer to the Ericsson complaint on December 17, 2010 where it asserted the affirmative defenses of noninfringement and invalidity of the asserted patents. On March 1, 2011, the defendants filed a motion to transfer venue to the District Court for the Northern District of California and their memorandum of law in support thereof. On March 21, 2011, Ericsson filed its opposition to the motion, and on April 1, 2011, defendants filed their reply to Ericsson's opposition to the motion to transfer. On June 8, 2011, Ericsson filed an amended complaint that added Dell, Toshiba and Belkin as defendants. At the status conference held on Jun 9, 2011, the Court set a Markman hearing for June 28, 2012 and trial for June 3, 2013. On June 14, 2011, Ericsson submitted its infringement contentions against the Company. On September 29, 2011, the Court denied the defendants' motion to transfer venue to the Northern District of California. In advance of the Markman hearing, the parties on March 9, 2012 exchanged proposed constructions of claim terms and on April 9, 2012 filed the Joint Claim Construction Statement with the District Court. On May 8, 2012, Ericsson submitted its opening Markman brief and on June 1, 2012 the defendants submitted their responsive Markman brief. Ericsson's Reply Markman brief was submitted June 15, 2012, and on June 28, 2012 the Markman hearing was held in the Eastern District of Texas. On June 21, 2012, Ericsson dismissed the '468 Patent (“Multi-purpose base station”) with prejudice and gave the Company a covenant not to sue as to products in the marketplace now or in the past. On June 22, 2012, Intel filed its Complaint in Intervention, meaning that Intel became an official defendant in the Ericsson case. The parties thereafter completed fact discovery and exchanged expert reports. During the exchange of the expert reports, Ericsson dropped the '516 patent (the OFDM “pulse shaping” patent). In addition, Ericsson dropped the '223 Patent (packet discard patent) against all the defendants' products, except for those products that use Intel chips. Thus, Ericsson has now dropped the '468 Patent (wireless base station), the '516 Patent (OFDM pulse shaping), and the '223 Patent (packet discard patent) for all non-Intel products. The five remaining patents are all only asserted against 802.11-compliant products.
	At a Court ordered mediation in Dallas on January 15, 2013, the parties did not come to an agreement to settle the litigation. On March 8, 2013, the parties received the Markman (claim construction) Order in response to the claim construction briefing and claim construction hearing.
	A jury trial in the Ericsson case occurred in the Eastern District of Texas from June 3 through June 13, 2013. After hearing the evidence, the jury found no infringement of the '435 and '223 patents, and the jury found infringement of claim 1 of the '625 patent, claims 1 and 5 of the '568 patent, and claims 1 and 2 of the '215 patent. The jury also found that there was no willful infringement by any defendant. Additionally, the jury found no invalidity of the asserted claims of the '435 and '625 patents. The jury assessed the following damages against the defendants: D-Link: $435,000; NETGEAR: $3,555,000; Acer/Gateway: $1,170,000; Dell: $1,920,000; Toshiba: $2,445,000; Belkin: $600,000. The damages awards equate to 15 cents per unit for each accused 802.11 device sold by each defendant. Thus, unless the defendants' various appeals are successful, the Company will likely have a 15 cent per unit obligation on its 802.11 devices until 2016 (when one infringed patent in suit expires), 10 cent per unit obligation from 2016 through 2018 (when a second infringed patent in suit expires), and a 5 cent per unit obligation from 2018 through 2020 (when the third and last infringed patent in suit expires).
	The Company and other defendants submitted various post-trial motions and briefs to the Court for its consideration, including motions and briefs for judgment as a matter of law in favor of defendants on non-infringement and invalidity of the patents in suit and for a reduction in damages, and the defendants have also moved for a new trial. These motions were argued before the Court on July 16, 2013. On August 6, 2013, the Court issued its orders on the various JMOL's (“Judgment as a Matter of Law”) and other post-trial motions. The Court denied all the defendants’ motions and set the reasonable and nondiscriminatory (RAND) royalty rate for the infringed patents equivalent to the jury verdict of 15 cents per unit.
	After negotiations, Ericsson and the Company agreed to the following as collateral while the appeal of the verdict, Court’s rulings, and the RAND royalty rate are pending. Ericsson will forego collecting the $3,555,000 verdict plus various fees (Prejudgment interest of $224,141; Post-judgment interest of $336 per day; Costs of $41,667) assigned to the Company pending appeal, so long as a Company representative declares and provides Ericsson with adequate quarterly assurances that the judgment can still be paid. For the ongoing royalties of 15 cents per 802.11n or 802.11ac device sold by the company that the jury and Court awarded, the Company will place the ongoing royalty amount into the Court’s registry (escrow account) and will give Ericsson a corresponding royalty report until the Company’s appeals of the jury verdict, the Court’s orders, and the RAND royalty rate are exhausted.
	On December 16, 2013, the defendants submitted their appeal brief to the Federal Circuit. Ericsson’s reply brief is due on February 20, 2014. The defendants estimate that the appeals process will take about 18 months from the jury’s verdict to run its course. The Company accrued and expensed the $3,555,000 in damages during the second quarter of 2013 to satisfy the verdict.
	NETGEAR, Inc. v. Innovatio IP Ventures LLC.
	On November 16, 2011, the Company filed a declaratory judgment action in the District of Delaware for non-infringement and invalidity of 17 WiFi-related patents brought in the approximately 15 actions throughout the United States by Innovatio IP Ventures LLC (“Innovatio”) against end user customers of the Company and other companies. Shortly after filing the declaratory judgment action, the Company filed a response supporting Cisco Systems, Inc.'s ("Cisco") and Motorola Solutions, Inc.'s ("Motorola") Motion to Transfer for Coordinated Pretrial Proceedings Pursuant to 28 U.S.C. § 1407 that was before the United States Judicial Panel on Multidistrict Litigation (“JPML”). On December 28, 2011, the JPML issued an order transferring the Innovatio actions throughout the United States, including the Company's declaratory judgment action, to the United States District Court for the Northern District of Illinois. Thus, the Company's declaratory judgment action and approximately 15 other similar cases will now proceed in the Northern District of Illinois in a consolidated fashion. On July 10, 2012, Innovatio answered the Declaratory Judgment Complaint filed by the Company with various counterclaims, cross claims, and affirmative defenses. In its answer, Innovatio accused the Company of infringing six WiFi-related patents in addition to the 17 WiFi-related patents on which the Company brought its declaratory judgment action of non-infringement and invalidity. The Company filed its answer to Innovatio's various counterclaims, cross claims, and affirmative defenses on August 3, 2012. In addition, on October 1, 2012, Cisco, Motorola and the Company filed an amended complaint alleging racketeering, fraud, interference with contract, unfair business practices, and conspiracy, among other things, against Innovatio. On February 4, 2013, the Court dismissed the offensive claims of Cisco, Motorola, and the Company that alleged Innovatio was engaging in racketeering, fraud, and unfair business practices by demanding licensing fees from hotels, cafes and other businesses but left intact claims against Innovatio that allege breach of contract with respect to Innovatio's fair, reasonable, and nondiscriminatory (FRAND) royalty obligations. The parties have already exchanged their Final Infringement, Unenforceability and Invalidity Contentions and Damages contentions.
	The Court has implemented special damages-focused proceedings prior to proceeding to the liability or infringement phase of the case. Accordingly, the parties on July 18 and July 19, 2013 participated in a bench trial on essentiality. Because the plaintiff and defendants disagree as to whether approximately 230 patent claims asserted by Innovatio are essential to practicing the 802.11 standard, this bench trial was held to determine whether those claims are essential. Essential claims are subject to FRAND royalty obligations, and such royalty obligations are generally subject to lower rates than Innovatio is currently demanding from the parties it is accusing of infringing its patents. On July 26, 2013, the Court issued an order deeming all claim essential. The Court reviewed various arguments on the IEEE's definition of “Essential Patent Claims” and found that essential patent claims are those which are necessary to implement mandatory or optional features but also can cover items not explicitly required by the standard -- either “enabling” technologies or items that are technically and commercially necessary to implement the standard. The Court confirmed its previous holding that the prospective licensee has the burden of proving essentiality, and that the analysis should be performed on a claim by claim basis, as opposed to a patent by patent basis. The Court then held a bench trial, which began on September 9, 2013, and ended on September 19, 2013, to determine what the FRAND royalty rate would be on the patents and claims earlier found to be essential by the Court. The Court ruled on September 25, 2013 that the FRAND royalty for Innovatio's standard-essential Wi-Fi patents would be 9.56 cents per unit, far lower than the several dollars per unit that Innovatio had sought. Innovatio’s method would have valued the patents at rates ranging from $3.39 per unit for a wireless router to $16.17 per unit for a tablet. The Court also determined that the correct royalty base for making a FRAND determination is the price of the Wi-Fi chip embedded in each product, finding the patents made up a small part of the value of the chip. Innovatio had said the rate should be based on the selling price for accused products, which could run to hundreds of dollars and lead to royalties of many dollars per unit. The Court concluded that Innovatio's expert witnesses presented "no legally sound and factually credible method" for calculating the FRAND rate based on the price of the whole product, leaving it no choice but to base its analysis on the price of the chip.
	On November 22, 2013, during a court-ordered mediation, Innovatio and the Company agreed to settle the case for a payment from the Company to Innovatio in return for a fully-paid-up license to the patents in suit, their foreign counterparts, and any other patents that Innovatio currently holds. The settlement did not have a material financial impact to the Company.
	U.S. Ethernet Innovation, LLC v. NETGEAR, Inc.
	On June 22, 2012, U.S. Ethernet Innovations, LLC (“USEI”) sued the Company in the District Court for the Eastern District of Texas, alleging infringement of certain of its Ethernet-related patents: U.S. Patent Numbers 5,732,094 (“Method for automatic initiation of data transmission”); 5,434,872 (“Apparatus for automatic initiation of data transmission”); 5,299,313 (“Network interface with host independent buffer management”) and 5,530,874 (“Network adapter with an indication signal mask and an interrupt signal mask”). USEI is a patent holding entity with a nominal office in the Eastern District of Texas. The accused products include products such as the “Netgear RT311 Internet Gateway Router.” The Company received an extension until August 17, 2012 to answer the complaint. USEI has sued, in addition to the Company, the following companies on the same and other of its Ethernet-related patents: Ricoh Americas Corporation, TRENDnet, Inc., Xerox Corporation, Konica Minolta Business Solutions U.S.A., Inc., Freescale Semiconductor, Inc., Sharp Electronics Corporation, Digi International Inc., NetSilicon, Inc., Epson America, Inc., Cirrus Logic, Inc., Yamaha Corporation of America, Control4 Corporation, Samsung Electronics Co., Ltd., Samsung Electronics America, Inc., Samsung Telecommunications America, LLC, Samsung Austin Semiconductor, LLC, Oki Data Americas, Inc., STMicroelectronics N.V., and STMicroelectronics, Inc. (collectively, “Defendants”).
	The Company received a further extension to answer the complaint and answered on September 4, 2012 via a 12(b)(6) motion to dismiss the complaint for various reasons, including a lack of pleading specificity. USEI responded to the Company's motion to dismiss under Rule 12(b)(6) on September 21, 2012. The Company submitted its Reply in Support of its Motion to Dismiss on October 1, 2012.
	USEI served its infringement contentions on the Company on October 10, 2012. The Company filed its transfer motion for a transfer to the Northern District of California and supporting declarations on November 16, 2012. On December 3, 2012, Defendants filed their joint invalidity contentions.
	Because the Eastern District of Texas's preferred time for deciding motions to transfer is after the Markman hearing, the defendants filed a motion to stay the litigation pending the result of the Eastern District of Texas's decisions on the motion to transfer on January 29, 2013.
	The Court has consolidated for discovery purposes USEI's cases against the aforementioned defendants and scheduled a consolidated Markman hearing for April 4, 2013 for the asserted patents. The Court also indicated that the court would consider any of Defendants' transfer motions as soon as possible.
	On March 27, 2013, the Court issued a Memorandum Opinion and Order granting the Company's motion to transfer to the United States District Court for the Northern District of California, effective on April 16, 2013. In response, on April, 12, 2013, USEI filed a motion for clarification and/or reconsideration of the venue order. Specifically, USEI seeks to delay the transfer until the Markman order in the Eastern District of Texas case becomes final under the guise that it is more efficient to allow the Texas court to construe the terms. The Company opposed USEI's motion. The mediation in this case that was scheduled for May 15, 2013 was cancelled.
	On May 16, 2013, the Court in the Eastern District of Texas denied USEI's motion to reconsider the timing of transfer. Also, the Court sent notice that the Eastern District of Texas case is closed, and instructed the clerk to transfer the case immediately.
	On June 28, 2013, the new Court in the case of USEI against the Company (the District Court for the Northern District of California), held a combined Case Management Conference for the Company's newly transferred case and the case USEI has previously instigated against several other defendants, including several Ethernet chip manufacturers. At this Case Management Conference, the Court commented that the chip manufacturers should go to trial first. The Court also ruled that the Company is going to join on the same schedule as the other defendants and allowed the Company to file a new motion to dismiss with the citation of supplemental Northern District of California authority.
	One additional patent is asserted against the Company that is not asserted against the other Northern District of California defendants (the '874 Patent). The Court agreed that, if USEI and the Company cannot resolve '874 Patent claim construction issues, the Court will build in dates to the litigation schedule for doing so (i.e. a limited claim construction hearing on terms of the '874 Patent).
	In July 2013, the Company filed a new motion to dismiss, as specifically allowed by the Court at the initial case management conference in the Northern District of California. On August 12, 2013, the Court granted the Company’s motion to dismiss, but the Court granted USEI leave to amend its complaint. On August 26, 2013, USEI submitted its Amended Complaint, and on September 9, 2013, the Company filed its Answer and Counterclaims of noninfringement and invalidity of the patents in suit.
	On November 12, 2013, during a court ordered mediation, USEI and the Company agreed to settle the case for a payment from the Company to USEI in return for a fully-paid-up license to the patents in suit, their foreign counterparts, and any other patents that USEI currently holds. The settlement did not have a material financial impact to the Company.
	ReefEdge Networks, LLC v. NETGEAR, Inc.
	On September 17, 2012, the Company was sued by ReefEdge Networks, LLC, a non-practicing entity. The Company received an extension from the plaintiff until November 8, 2012 to answer the complaint and answered the complaint on that date.
	The complaint alleges that NETGEAR infringes three related patents: 6,633,761 B1; 6,975,864 B2; 7,197,308 B2. In general terms, these asserted patents involve seamlessly handing-off portable wireless devices from one access point to another so as to provide roaming within a wireless network.
	The complaint specifically accuses the Company's ProSafe wireless controller of infringing these three patents. On August 15, 2012, ReefEdge filed complaints in Delaware against Aruba Networks Inc., Cisco Systems Inc., Meru Networks Inc., and Ruckus Wireless Inc. alleging infringement of the same three patents. In the second tranche of lawsuits, ReefEdge sued--in addition to the Company-Brocade Communications Systems, Inc., Extreme Networks Inc., ADTRAN, Inc., Alcatel-Lucent Inc., D-Link Systems, Inc., Enterasys Networks, Inc., Motorola Solutions Inc., CDW Corporation, Avaya Inc., and ZyXEL Communications Corporation. The Company has hired defense counsel and is evaluating ReefEdge's allegations. During the third quarter of 2013, the Company submitted its initial disclosures to ReefEdge and also produced its core technical documents to ReefEdge. Discovery is ongoing. It is too early to reasonably estimate any financial impact to the Company because of this litigation matter.
	Pragmatus Telecom, LLC v. NETGEAR, Inc.
	On December 6, 2012, Pragmatus Telecom, LLC (“Pragmatus”), filed a lawsuit against the Company asserting that the Company's use of a system “to provide live chat service over the Internet” infringes U.S. Patent Nos. 6,311,231, 6,668,286, and 7,159,043 ("'231 patent", "'286 patent", and "'043 patent", respectively).
	The '231 patent is entitled "Method and System for Coordinating Data and Voice Communications via Customer Contact,” the '286 patent is entitled "Method and System for Coordinating Data and Voice Communications via Customer Contact Channel Changing System Over IP," and the '043 patent is entitled "Method and System for Coordinating Data and Voice Communications via Contact Channel Changing System," The patents very generally allegedly relate to “live chat" services of companies, which can give customers the ability to exchange text messages with a virtual or real customer support person. It appears that most companies named in the various lawsuits by Pragmatus license the “live chat” technology and software from a third-party supplier. A few of these third-party suppliers have been named in some of the over 100 lawsuits filed by Pragmatus in California, Delaware, and the Eastern District of Texas, and two third-party suppliers of text-chat (LivePerson and LogMeIn) have filed declaratory judgment actions on the patents in suit in Delaware. There is a pending reexamination on one of the three asserted patents.
	Pragmatus and the Company agreed to extend the deadline for the Company to answer or otherwise respond to Pragmatus's complaint until February 11, 2013. The Company answered the complaint on that day by denying Pragmatus's infringement allegations and requesting a declaratory judgment by the Court that the patents in suit are not infringed and invalid. On February 20, 2013, the Company filed a motion to stay the case, and, on March 6, 2013, Pragmatus filed its opposition to the Company's motion to stay the case. The Company filed its reply on March 13, 2013. On May 14, 2013, the Court granted the Company's motion to stay “pending final exhaustion of all pending reexamination proceedings.” On June 22, 2013, both the '231 and '286 patents, which were the two asserted patents against the Company that were put into reexam by the defendants in a parallel Delaware action and the basis of the stay in the Pragmatus' case against the Company, emerged from reexam. In addition, the Delaware court lifted the stay in the Pragmatus cases pending in Delaware. The parties submitted a status report to the Court in January of 2014 indicating that: (1) the ‘231 Patent emerged from reexamination with all claims confirmed, and all rights of appeal have been exhausted; (2) the request for reexamination of the ‘043 Patent was denied; and (3) all claims of the ’286 patent were confirmed during reexamination, but the reexamination requestor appealed the examiner’s decision and the matter is now on appeal. The parties have asked the Court to lift the stay of the case and set a case management conference and an early neutral evaluation.
It is too early to reasonably estimate any financial impact to the Company because of this litigation matter.
Freeny v. NETGEAR, Inc.
On April 29, 2013, the Company and several other companies, including Apple, ASUSTek, Belkin, Buffalo, D-Link, IC Intracom, Ruckus, TP-Link, Vizio, and Western Digital, were sued in separate actions in the Eastern District of Texas by Charles C. Freeny III, Bryan E. Freeny, and James P. Freeny. The complaint alleges that dual-band wireless routers infringe U.S. Patent No. 7,110,744. The patent lists Charles Freeny as the inventor. Mr. Freeny's sons, Charles III and Bryan, now own the '744 patent, as Mr. Freeny is deceased. On June 21, 2013, the Company's answer and counterclaims were timely filed with the Court. The initial status conference was held on August 8, 2013. At the status conference, the Markman hearing was scheduled for August 7, 2014, and the trial date was set for April 6, 2015.
On August 2, 2013, Freeny produced its initial infringement contentions to the Company. The Company’s initial disclosures were given to Freeny on September 23, 2013, and, on October 10, 2013, the Company produced initial technical documents, as required by the Court’s local rules. Discovery is ongoing.
It is too early to reasonably estimate any financial impact to the Company because of this litigation matter.
Concinnitas v. NETGEAR, Inc.
On May 2, 2013, the Company was added to an existing case against Sierra Wireless America, Inc. and Sierra Wireless S.A. that was brought by Concinnitas, LLC and George W. Hindman in the Eastern District of Texas. The accused products will be the Company's Aircard products that it acquired from Sierra Wireless. On July 20, 2013, the Company's answer and counterclaims were timely filed with the Court. The Court set an initial scheduling conference for September 5, 2013, and at that conference the Court consolidated Concinnitas’s case against the Company with Concinnitas’s case against Samsung for discovery and claims construction purposes. Based on the date of the scheduling conference, Concinnitas’s infringement contentions were submitted on August 30, 2013, and the Company’s invalidity contentions and technical document production were submitted on October 17, 2013. On December 19, 2013, the Company and Concinnitas settled the lawsuit for a payment from the Company to Concinnitas. The settlement grants the Company a license to the patent in suit - US Patent 7,805,542 “Mobile Unit Attached in a Mobile Environment That Fully Restricts Access to Data Received Via Wireless Signal to a Separate Computer in the Mobile Environment” and two related patents - US Patent 6,324,592 “Apparatus and Method For a Mobile Computer Architecture and Input/Output Management Systems” and US Patent 7,165,123 “Apparatus and Method for I/O Management in a Mobile Environment Wherein Access to Data From a Wireless Signal is Restricted Based on a Persistent Unique Hardware Identification.” The settlement payment has been made, and did not have a material financial impact to the Company.
NETGEAR, Inc. v. ASUS
On July 22, 2013, the Company filed a complaint against ASUSTEK COMPUTER, INC. and ASUS COMPUTER INTERNATIONAL, INC. (collectively “ASUS”) seeking permanent injunctive relief, damages and declaratory relief for false advertising in violation of the Lanham Act, damages for tortious interference with the Company's prospective business relations, injunctive relief for unfair competition in violation of California Business and Professions Code, injunctive relief for false advertising pursuant to California Business and Professions Code, damages and injunctive relief pursuant the Sherman Antitrust Act, and various forms of declaratory relief.
The Company has asserted that contrary to ASUS's representations to the Federal Communications Commission (“FCC”), ASUS's wireless routers, including without limitation models RT-N65U and RT-AC66U, produce power outputs far in excess of those represented to the FCC, produce power outputs that exceed FCC maximum output levels, unlawfully cause interference with adjacent bandwidths (potentially including critically important navigation, communications, and safety devices), and operate in a manner that has never been accurately reported to the FCC. The Company contends that ASUS's representations that its RT-N65U and RT-AC66U wireless routers are FCC compliant are false, and are made with the intent to deceive potential consumers. The Company further contends that ASUS's misrepresentations regarding compliance of its wireless routers with the FCC regulations constitute unfair competition and false advertising, tortuously interfere with the Company's prospective business advantage, and have harmed the Company because the Company has lost expected sales due to such wrongful conduct and misrepresentations by ASUS.
After a series of extensions to answer the complaint granted by the Company to Asus, on September 3, 2013, Asus filed a motion to dismiss the complaint. Asus’s motion was generally based on the following arguments: a) the Company’s claims are preempted by FCC regulations; b) the Company is improperly seeking a private cause of action for violation of FCC regulations that create no such cause of action; c) the Company’s claims should be stayed or dismissed in deference to the primary jurisdiction of the FCC; and d) the Company fails to allege with sufficient specificity the nature of defendants' wrongful conduct nor how that conduct caused injury to the Company.
On October 7, 2013, the Company responded to Asus’s motion to dismiss by arguing that: a) the defendants violated unambiguous FCC regulations, thus, the Company's claims are in harmony, not conflict, with the FCC's regulatory goals; b) the Company’s damages arise not from defendants' private, regulatory dealings with the FCC, but rather from Asus’s conduct in the marketplace -- a realm regulated not by the FCC but by the courts; c) the Court should be allowed to adjudicate garden variety claims of false advertising, unfair competition, and deceptive trade practices that in no way implicate complex regulatory interpretations or policy judgments; and d) the complaint pleads facts in exacting detail.
On December 12, 2013, the Court refused to dismiss the Company’s antitrust and false advertising suit against Asus by denying Asus’s motion, thereby indicating that proceeding with the case would not violate the FCC’s authority. Discovery in this case has commenced.
Spansion LLC v. NETGEAR, Inc.
On August 1, 2013, Spansion LLC (“Spansion”) filed a section 337 complaint with the U.S. International Trade Commission (“ITC”) naming: the Company; Belkin International, Inc. (“Belkin”); ASUSTek Computer Inc. and Asus Computer International (collectively, “Asus”); D-Link Corporation and D-Link System, Inc. (collectively, “D-Link”); Nintendo Co., Ltd. and Nintendo of America, Inc. (collectively, “Nintendo”); and Macronix America, Inc., Macronix Asia Limited, and Macronix (Hong Kong) Co., Ltd. (collectively “Macronix”), as proposed respondents. The Complaint is styled Certain Flash Memory Chips and Products Containing the Same. Spansion is seeking a general exclusion order, or in the alternative a limited exclusion order, as well as a cease and desist order.
Spansion has asserted six patents related to the manufacture, structure, and operation of flash memory cells, as well as security protection systems for flash memory devices:
•	US Patent No. 6,369,416 “Semiconductor Device with Contacts Having a Sloped Profile
•	US Patent No. 6,459,625 “Three Metal Process for Optimizing Layout Density”
•	US Patent No. 6,731,536 “Password and Dynamic Protection of Flash Memory Data”
•	US Patent No. 6,900,124 “Patterning for Elliptical Vss Contact on Flash Memory
•	US Patent No. 7,018,922 “Patterning for Elongated Vss Contact on Flash Memory
•	US Patent No. 7,151,027 “Method and Device for Reducing Interface Area of a Memory Device”
Four of the asserted patents, the '416, '625, '124, and '922 patents, were previously asserted by Spansion in the 337-TA-735 Investigation against Samsung, Apple, Nokia, PNY, RIM, and Transcend. ITC records indicate the 735 Investigation terminated based on settlement agreements prior to the hearing on the merits.
The accused products are identified as flash memory chips manufactured and sold by Macronix, as well as downstream products which contain the accused Macronix flash memory chips. The Complaint specifically identifies the Company WNR1000 wireless router, as an exemplary accused product, but makes clear that Spansion intends to expand the scope of accused products to include additional products, if any, which contain the accused Macronix flash memory chips.
In addition, on August 1, 2013, Spansion filed a parallel similar complaint against the same parties in the Northern District of California. Discovery in the ITC case has commenced and is ongoing, and the Northern District of California case has been stayed pending the outcome of the ITC case.
It is too early to reasonably estimate any financial impact to the Company because of this litigation matter.
Garnet Digital v. NETGEAR, Inc.
On September 9, 2013, the Company was sued in the Eastern District of Texas by a non-practicing entity named Garnet Digital (“Garnet”) that is based in Texas. There is one asserted patent, U.S. Pat. No. 5,379,421, which is directed to an interactive terminal for the access of remote database information. Garnet is alleging infringement by the Company by its products or systems, such as the NTV200, that are responsive to output signals from a telephone.
The patent has previously been litigated against Apple, Samsung, RIM, and a number of other wireless companies in Eastern Texas and the ITC. Garnet’s lawsuit against the Company is one of multiple cases filed by Garnet in the Eastern District of Texas Other defendants sued by Garnet in the Eastern District of Texas include: Boxee, D-Link Systems, Logitech, Roku, TiVo, DirecTV, DISH Network, Verizon, AT&T, Comcast, Panasonic, Western Digital, Pioneer, Yamaha, Denon, D&M Holdings, Marantz, and Onkyo. The Company answered the complaint on December 9, 2013 by asserting various affirmative defenses. In February of 2014, the court consolidated the Company’s case with the other pending Garnet Digital cases in the Eastern District of Texas, but the Court has not yet set a scheduling conference.

Penovia LLC v. NETGEAR, Inc.
On September 27, 2013, a non-practicing entity named Penovia LLC (“Penovia”) filed suit against the Company in the Eastern District of Texas. Penovia asserts the Company’s wireless routers infringe U.S. Patent No. 5,822,221 (the “’221 patent”), entitled “Office Machine Monitoring Device.” Penovia’s complaint specifically names the DGN2000 Wireless-N product as an example of an infringing product. Penovia admits in the complaint that the ’221 patent expired on October 13, 2010, due to a lapse in maintenance fee payments. Consequently, Penovia seeks damages for an approximately three year period of time starting six years before the filing date of the complaint, September 27, 2007, and ending on October 13, 2010. Penovia has asserted the ’221 patent in 22 cases, all in the Eastern District of Texas. Penovia filed nine cases on May 21, 2013, and filed the remainder on September 27, 2013. The Company filed its answer on November 26, 2014 - asserting various affirmative defenses. On December 23, 2013 received Penovia’s infringement contentions.

Innovative Wireless Solutions LLC v. NETGEAR, Inc.
In November of 2013, Innovative Wireless Solutions filed a new wave of suits targeting 14 wireless router and networking companies, Adtran, Arris, Aruba Networks, Belkin, Buffalo Technology, Engenius Technologies, Fortinet, IC Intracom, Motorola Solutions, SMC Networks, Ubiquiti Networks, Western Digital, and Zoom Telephonics. Previously, in April of 2013, Innovative Wireless had filed 41 suits targeting hotels and restaurant chains over wireless Internet services. The Company was sued on November 6, 2013 in the District of Delaware.
The three patents-in-suit (5,912,895 entitled “Information network access apparatus and methods for communicating information packets via telephone lines” ( the “‘895 Patent”); 6,327,264 entitled “Information network access apparatus and methods for communicating information packets via telephone lines” ( the “’264 Patent”); and 6,587,473 entitled “Information network access apparatus and methods for communicating information packets via telephone lines” ( the “‘473 Patent”) originally were part of a portfolio of Nortel Networks’ patents before they reached Innovative Wireless in March 2013.
The Company filed its answer on January 13, 2014, asserting various affirmative defenses. It is too early to reasonably estimate any financial impact to the Company because of this litigation matter.
IP Indemnification Claims
In its sales agreements, the Company typically agrees to indemnify its direct customers, distributors and resellers (the “Indemnified Parties”) for any expenses or liability resulting from claimed infringements by the Company's products of patents, trademarks or copyrights of third parties that are asserted against the Indemnified Parties, subject to customary carve outs. The terms of these indemnification agreements are generally perpetual after execution of the agreement. The maximum amount of potential future indemnification is generally unlimited. From time to time, the Company receives requests for indemnity and may choose to assume the defense of such litigation asserted against the Indemnified Parties.
Environmental Regulation
The European Union (“EU”) enacted the Waste Electrical and Electronic Equipment Directive, which makes producers of electrical goods, including home and commercial business networking products, financially responsible for specified collection, recycling, treatment and disposal of past and future covered products. The deadline for the individual member states of the EU to transpose the directive into law in their respective countries was August 13, 2004 (such legislation, together with the directive, the “WEEE Legislation”). Producers participating in the market were financially responsible for implementing these responsibilities under the WEEE Legislation beginning in August 13, 2005. The Company adopted the authoritative guidance for asset retirement and environmental obligations in the third quarter of fiscal 2005 and has determined that its effect did not have a material impact on the Company's consolidated results of operations and financial position for years ended December 31, 2013 and 2012. The WEEE Directive was recast on July 24, 2012, published on August 13, 2012, and was implemented by all member states on February 14, 2014. The Company expects no material impact on its consolidated results of operations and financial positions due to this recasting. Similar WEEE Legislation has been or may be enacted in other jurisdictions, including in the United States, Canada, Mexico, China, India, Australia and Japan. The Company continues to monitor WEEE Legislation and similar legislation in other jurisdictions as individual countries issue their implementation guidance. The Company believes it has met the applicable requirements of current WEEE Legislation and similar legislation in other jurisdictions, to the extent implementation requirements has been published.
Additionally, the EU enacted the Restriction of Hazardous Substances Directive (“RoHS Legislation”), the REACH Regulation, Packaging Directive and the Battery Directive. EU RoHS Legislation, along with similar legislation in China, requires manufacturers to ensure certain substances, including polybrominated biphenyls (“PBD”), polybrominated diphenyl ethers (“PBDE”), mercury, cadmium, hexavalent chromium and lead (except for allowed exempted materials and applications), are below specified maximum concentration values in certain products put on the market after July 1, 2006. The RoHS Directive was recast on July 21, 2011 and went into force on January 3, 2013. This did not have a material impact on the Company's consolidated results of operations and financial position. The REACH Regulation requires manufacturers to ensure the published lists of substances of very high concern in certain products are below specified maximum concentration values. The Battery Directive controls use of certain types of battery technology in certain products and requires mandatory marking. The Company believes it has met the requirements of the RoHS Directive Legislation, the REACH Regulation and the Battery Directive Legislation.
Additionally, the EU enacted the Energy Using Product (“EuP”) Directive, which came into force in August 2007. The EuP Directive required manufacturers of certain products to meet minimum energy efficiency performance requirements. These requirements were documented in EuP implementing measures issued for specific product categories. The implementing measures affecting the Company's products are minimum power supply efficiencies and may include required equipment standby modes, which also reduce energy consumption. The EuP Directive was repealed in November 2009 and replaced by the Energy Related Products ("ErP") Directive, which includes the same implementing measures of the former EuP Directive and new implementing measures applicable to the Company's products. The Company is in compliance with applicable implementing measures of the ErP Directives since it came into force.
Additionally, in 2010, the U. S. Congress passed the Dodd-Frank Wall Street Reform and Consumer Protection Act. Pursuant to Section 1502 of the Dodd-Frank Act, in August 2012, the U.S. Securities and Exchange Commission adopted Rule 13p-1 under the Securities Exchange Act of 1934, as amended. Rule 13p-1 is commonly known as the “Conflict Minerals Rule.” This rule is intended to address human rights violations arising from the forced labor, child labor, rape, murder and other hostilities related to mining operations in Africa, namely in the eastern Democratic Republic of the Congo (“DRC”) and nearby regions. This rule requires public companies to make disclosures regarding whether specified minerals in company products are sourced from the DRC or its surrounding countries (covered countries) in an effort to encourage companies to obtain these minerals from sources that do not directly or indirectly finance or benefit armed groups operating in these countries. The specified minerals, referred to as conflict minerals, are Tin, Tungsten, Tantalum and Gold, which are necessary in the manufacture of electronics components and equipment. Publicly traded companies, such as the Company, will be required to disclose certain information concerning the origin of conflict minerals contained in their products. In addition, the Organization for Economic Co-operation and Development (“OECD”) has published Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas. The Company intends to utilize this internationally recognized OECD framework to conduct any required due diligence under the Conflict Minerals Rule. The Company is currently in the process of assessing compliance and does not believe there will be any material financial or business impact on the Company as a result.

	Common Stock Repurchase Programs
	In October 21, 2008, the Company’s Board of Directors authorized management to repurchase up to 6.0 million shares of the Company’s outstanding common stock. Under this authorization, the timing and actual number of shares subject to repurchase are at the discretion of management and are contingent on a number of factors, such as levels of cash generation from operations, cash requirements for acquisitions and the price of the Company’s common stock. The Company repurchased 2.0 million shares or $63.1 million of common stock under this authorization during the year ended December 31, 2013. The Company did not repurchase any shares under this authorization during the years ended December 31, 2012 and 2011.
	The Company repurchased approximately 14,000 shares, or $0.5 million of common stock under a repurchase program to help administratively facilitate the withholding and subsequent remittance of personal income and payroll taxes for individuals receiving RSUs during the year ended December 31, 2013. Similarly, during the years ended December 31, 2012 and December 31, 2011, the Company repurchased approximately 22,000 shares and 25,000 shares, respectively, or $0.9 million and $0.9 million of common stock, respectively, under the same program to help facilitate tax withholding for RSUs.
	These shares were retired upon repurchase. The Company’s policy related to repurchases of its common stock is to charge the excess of cost over par value to retained earnings. All repurchases were made in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended.

	Employee Benefit Plans
	2000 Stock Option Plan
	In April 2000, the Company adopted the 2000 Stock Option Plan (the “2000 Plan”). The 2000 Plan provides for the granting of stock options to employees and consultants of the Company. Options granted under the 2000 Plan may be either incentive stock options (“ISOs”) or nonqualified stock options (“NSOs”). ISOs may be granted only to Company employees (including officers and directors who are also employees). NSOs may be granted to Company employees, directors and consultants. A total of 7,350,000 shares of Common Stock have been reserved for issuance under the 2000 Plan.
	Options under the 2000 Plan may be granted for periods of up to ten years, provided, however, that (i) the exercise price of an ISO and NSO shall not be less than the estimated fair value of the underlying stock on the date of grant and (ii) the exercise price of an ISO and NSO granted to a 10% shareholder shall not be less than 110% of the estimated fair value of the underlying stock on the date of grant. To date, options granted generally vest over four years.
	As discussed below, in April 2003, all remaining shares reserved but not issued under the 2000 Plan were transferred to the 2003 Stock Plan.
	2003 Stock Plan
	In April 2003, the Company adopted the 2003 Stock Plan (the “2003 Plan”). The 2003 Plan provides for the granting of stock options to employees and consultants of the Company. Options granted under the 2003 Plan may be either ISOs or NSOs. ISOs may be granted only to Company employees (including officers and directors who are also employees). NSOs may be granted to Company employees, directors and consultants. The Company has reserved 750,000 shares of Common Stock plus any shares which were reserved but not issued under the 2000 Plan as of the date of the approval of the 2003 Plan. The number of shares which were reserved but not issued under the 2000 Plan that were transferred to the Company’s 2003 Plan were 615,290, which when combined with the shares reserved for the Company’s 2003 Plan total 1,365,290 shares reserved under the Company’s 2003 Plan as of the date of transfer. Any options cancelled under either the 2000 Plan or the 2003 Plan are returned to the pool available for grant. During the second quarter of 2013, the Company's 2003 Stock Plan expired and the remaining unissued 62,791 reserved shares were retired accordingly.
	Options under the 2003 Plan may be granted for periods of up to ten years, provided, however, that (i) the exercise price of an ISO and NSO shall not be less than the estimated fair value of the underlying stock on the date of grant and (ii) the exercise price of an ISO and NSO granted to a 10% shareholder shall not be less than 110% of the estimated fair value of the underlying stock on the date of grant. To date, options granted generally vest over four years, with the first tranche vesting at the end of 12 months and the remaining shares underlying the option vesting monthly over the remaining three years. In fiscal 2005, certain options granted under the 2003 Plan immediately vested and were exercisable on the date of grant, and the shares underlying such options were subject to a resale restriction which expires at a rate of 25% per year.
	2006 Long Term Incentive Plan
	In April 2006, the Company adopted the 2006 Long Term Incentive Plan (the “2006 Plan”), which was approved by the Company’s stockholders at the 2006 Annual Meeting of Stockholders on May 23, 2006. The 2006 Plan provides for the granting of stock options, stock appreciation rights, restricted stock, performance awards and other stock awards, to eligible directors, employees and consultants of the Company. Upon the adoption of the 2006 Plan, the Company reserved 2,500,000 shares of common stock for issuance under the 2006 Plan. In June 2008, the Company adopted amendments to the 2006 Plan which increased the number of shares of the Company’s common stock that may be issued under the 2006 plan by an additional 2,500,000 shares. In July 2010, the Company adopted amendments to the 2006 Plan which increased the number of shares of the Company’s common stock that may be issued under the 2006 plan by an additional 1,500,000 shares. In June 2012, the Company adopted amendments to the 2006 Plan which increased the number of shares of the Company’s common stock that may be issued under the 2006 plan by an additional 3,000,000 shares. In addition, RSUs granted under the 2006 Plan on or after June 6, 2012 are counted against shares authorized under the plan as 1.58 shares of common stock for each share subject to such award. As of December 31, 2013, 1,366,297 shares were reserved for future grants under the 2006 Plan.
	Options granted under the 2006 Plan may be either ISOs or NSOs. ISOs may be granted only to Company employees (including officers and directors who are also employees). NSOs may be granted to Company employees, directors and consultants. Options may be granted for periods of up to ten years, provided, however, that (i) the exercise price of an ISO and NSO shall not be less than the estimated fair value of the underlying stock on the date of grant and (ii) the exercise price of an ISO and NSO granted to a 10% shareholder shall not be less than 110% of the estimated fair value of the underlying stock on the date of grant. Options granted under the 2006 Plan generally vest over four years, with the first tranche vesting at the end of 12 months and the remaining shares underlying the option vesting monthly over the remaining three years.
	Stock appreciation rights may be granted under the 2006 Plan subject to the terms specified by the plan administrator, provided that the term of any such right may not exceed ten (10) years from the date of grant. The exercise price generally cannot be less than the fair market value of the Company’s common stock on the date the stock appreciation right is granted.
	Restricted stock awards may be granted under the 2006 Plan subject to the terms specified by the plan administrator. The period over which any restricted award may fully vest is generally no less than three (3) years. Restricted stock awards are non-vested stock awards that may include grants of restricted stock or grants of restricted stock units (“RSUs”). Restricted stock awards are independent of option grants and are generally subject to forfeiture if employment terminates prior to the release of the restrictions. During that period, ownership of the shares cannot be transferred. Restricted stock has the same voting rights as other common stock and is considered to be currently issued and outstanding. RSUs do not have the voting rights of common stock, and the shares underlying the RSUs are not considered issued and outstanding. The Company expenses the cost of the restricted stock awards, which is determined to be the fair market value of the shares at the date of grant, ratably over the period during which the restrictions lapse.
	Performance awards may be in the form of performance shares or performance units. A performance share means an award denominated in shares of Company common stock and a performance unit means an award denominated in units having a dollar value or other currency, as determined by the plan administrator. The plan administrator will determine the number of performance awards that will be granted and will establish the performance goals and other conditions for payment of such performance awards. The period of measuring the achievement of performance goals will be a minimum of twelve (12) months.
	Other stock-based awards may be granted under the 2006 Plan subject to the terms specified by the plan administrator. Other stock-based awards may include dividend equivalents, restricted stock awards, or amounts which are equivalent to all or a portion of any federal, state, local, domestic or foreign taxes relating to an award, and may be payable in shares, cash, other securities or any other form of property as the plan administrator may determine.
	In the event of a change in control of the Company, all awards under the 2006 Plan vest in full and all outstanding performance shares and performance units will be paid out upon transfer.
	Any shares of common stock subject to an award that is forfeited, settled in cash, expires or is otherwise settled without the issuance of shares shall again be available for awards under the 2006 Plan. Additionally, any shares that are tendered by a participant of the 2006 Plan or retained by the Company as full or partial payment to the Company for the purchase of an award or to satisfy tax withholding obligations in connection with an award shall no longer again be made available for issuance under the 2006 Plan.
	Employee Stock Purchase Plan
	The Company sponsors an Employee Stock Purchase Plan (the “ESPP”), pursuant to which eligible employees may contribute up to 10% of compensation, subject to certain income limits, to purchase shares of the Company’s common stock. Employees may purchase stock semi-annually at a price equal to 85% of the fair market value on the purchase date. Since the price of the shares is determined at the purchase date, the Company recognizes expense based on the 15% discount at purchase. For the years ended December 31, 2013, 2012, and 2011, ESPP compensation expense was $420,000, $371,000 and $354,000, respectively. As of December 31, 2013, 307,500 shares were reserved for future grants under the ESPP.

This amount changes based on the fair market value of the Company’s stock. Total intrinsic value of options exercised for the year ended December 31, 2013, 2012, and 2011 was $4.2 million, $8.1 million and $21.8 million, respectively.
	The total fair value of options vested during the years ended December 31, 2013, 2012, and 2011 was $13.0 million, $11.1 million and $9.8 million, respectively.

The total fair value or RSUs, or the grant date fair value of RSUs, vested during the years ended December 31, 2013, 2012 and 2011 was $2.3 million, $3.0 million and $2.6 million, respectively.
Valuation and Expense Information
The Company measures stock-based compensation at the grant date based on the fair value of the award. Estimated compensation cost relating to restricted stock units (“RSUs”) is based on the closing fair market value of the Company’s common stock on the date of grant. The fair value of Employee Stock Purchase Plan (“ESPP”) is based on the 15% discount at purchase, since the price of the shares is determined at the purchase date. The fair value of each option award is estimated on the date of grant using a Black-Scholes-Merton option valuation model that uses the assumptions noted in the following table. The estimated expected term of options granted is derived from historical data on employee exercise and post-vesting employment termination behavior. The risk free interest rate is based on the implied yield currently available on U.S. Treasury securities with a remaining term commensurate with the estimated expected term. Expected volatility is based on historical volatility over the most recent period commensurate with the estimated expected term.
The following table sets forth the weighted-average assumptions used to fair value option grants during the years ended December 31, 2013, 2012 and 2011 based on its historical experience:
	Year Ended December 31,
	2013		2012			2011
Expected life (in years)	4.4		4.4			4.4
Risk-free interest rate	0.72	%	0.64	%		1.63	%
Expected volatility	48.05	%	52.09	%		50.31	%
Dividend yield	—		—			—
The weighted average estimated fair value of options granted during the years ended December 31, 2013, 2012 and 2011 was $13.29, $13.99 and $14.29, respectively.
The following table sets forth the total stock-based compensation expense resulting from stock options, restricted stock awards, and the Employee Stock Purchase Plan included in the Company’s Consolidated Statements of Operations (in thousands):
	Year Ended December 31,
	2013			2012				2011
Cost of revenue	$	1,577		$	1,347			$	999
Research and development	3,943			2,787				2,476
Sales and marketing	5,379			4,751				5,136
General and administrative	6,563			5,487				5,151
Total	$	17,462		$	14,372			$	13,762
The Company recognizes these compensation costs net of the estimated forfeitures on a straight-line basis over the requisite service period of the award, which is generally the option vesting term of four years.
Total stock-based compensation cost capitalized in inventory was less than $0.5 million in each of the years ended December 31, 2013, 2012 and 2011.
As of December 31, 2013, $16.7 million of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 2.3 years. As of December 31, 2013, $14.0 million of total unrecognized compensation cost related to non-vested RSUs is expected to be recognized over a weighted-average period of 3.0 years.
401(k) Plan
In April 2000, the Company adopted the NETGEAR 401(k) Plan to which employees may contribute up to 100% of salary subject to the legal maximum. In the first quarter of 2012, the Company began matching 50% of contributions for employees that remain active with the company through the end of the fiscal year, up to a maximum of $6,000 in employee contributions. During the years ended December 31, 2013 and 2012 the Company recognized $1.0 million and $0.7 million, respectively, in expenses related to the 401(k) match. No match was offered in 2011 and thus no expenses were recorded related to matching employee contributions during that year.

Segment Reporting [Abstract]	'
Segment Information, Operations By Geographic Area And Customer Concentration	'
	Segment Information, Operations by Geographic Area and Customer Concentration
	Operating segments are components of an enterprise about which separate financial information is available and is regularly evaluated by management, namely the Chief Operating Decision Maker (“CODM”) of an organization, in order to determine operating and resource allocation decisions. By this definition, the Company operates in three specific business units: retail, commercial, and service provider. The retail business unit consists of high performance, dependable and easy-to-use home networking, home video monitoring, storage and digital media products. The commercial business unit consists of business networking, storage and security solutions that bring enterprise class functionality down to the small and medium size business at an affordable price. The service provider business unit consists of made-to-order and retail proven, whole home networking hardware and software solutions as well as 4G LTE hotspots sold to service providers for sale to their subscribers. Each business unit is managed by a Senior Vice President/General Manager. The Company believes this structure enables it to better focus its efforts on the Company's core customer segments and allows it to be more nimble and opportunistic as a company overall.
	The results of the reportable segments are derived directly from the Company's management reporting system. The results are based on the Company's method of internal reporting and are not necessarily in conformity with accounting principles generally accepted in the United States. Management measures the performance of each segment based on several metrics, including contribution income. Segment contribution income includes all product line segment revenues less the related cost of sales, research and development and sales and marketing costs. Contribution income is used, in part, to evaluate the performance of, and allocate resources to, each of the segments. Certain operating expenses are not allocated to segments because they are separately managed at the corporate level. These unallocated indirect costs include corporate costs, such as corporate research and development, general and administrative costs, stock-based compensation expenses, amortization of intangibles, acquisition-related integration costs, restructuring costs, litigation reserves and interest and other income (expense), net. The Company does not evaluate operating segments using discrete asset information.
	Financial information for each reportable segment and a reconciliation of segment contribution income to income before income taxes is as follows (in thousands, except percentage data):

Fair Value Of Financial Instruments	'
	Fair Value Measurements
	The Company determines the fair values of its financial instruments based on a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. The fair value hierarchy prioritizes the inputs into three levels that may be used to measure fair value:
	Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
	Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability;
	Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
	The following tables summarize assets and liabilities measured at fair value on a recurring basis as of December 31, 2013 and 2012 (in thousands):

	The Company's investments in cash equivalents and available-for-sale securities are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets. The Company enters into foreign currency forward contracts with only those counterparties that have long-term credit ratings of A+/A2 or higher. The Company's foreign currency forward contracts are classified within Level 2 of the fair value hierarchy as they are valued using pricing models that take into account the contract terms as well as currency rates and counterparty credit rates. The Company verifies the reasonableness of these pricing models using observable market data for related inputs into such models. Additionally, the Company includes an adjustment for non-performance risk in the recognized measure of fair value of derivative instruments. At December 31, 2013 and December 31, 2012, the adjustment for non-performance risk did not have a material impact on the fair value of the Company's foreign currency forward contracts. The carrying value of non-financial assets and liabilities measured at fair value in the financial statements on a recurring basis, including accounts receivable and accounts payable, approximate fair value due to their short maturities.

Organization, Consolidation and Presentation of Financial Statements [Abstract]	'
Basis of Presentation [Policy Text Block]	'
	Basis of presentation
	The accompanying consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All inter-company accounts and transactions have been eliminated in the consolidation of these subsidiaries.
Fiscal Periods [Policy Text Block]	'
	Fiscal periods
	The Company's fiscal year begins on January 1 of the year stated and ends on December 31 of the same year. The Company reports its results on a fiscal quarter basis rather than on a calendar quarter basis. Under the fiscal quarter basis, each of the first three fiscal quarters ends on the Sunday closest to the calendar quarter end, with the fourth quarter ending on December 31.
Use of Estimates [Policy Text Block]	'
	Use of estimates
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates.
Cash and Cash Equivalents [Policy Text Block]	'
	Cash and cash equivalents
	The Company considers all highly liquid investments with an original maturity at the time of purchase of three months or less to be cash equivalents. The Company deposits cash and cash equivalents with high credit quality financial institutions.
Short-Term Investment [Policy Text Block]	'
	Short-term investments
	Short-term investments are partially comprised of marketable securities that consist of government securities with an original maturity or a remaining maturity at the time of purchase, of greater than three months and no more than 12 months. The marketable securities are held in the Company's name with one high quality financial institution, which acts as the Company's custodian and investment manager. These marketable securities are classified as available-for-sale securities in accordance with the provisions of the authoritative guidance for investments and are carried at fair value with unrealized gains and losses reported as a separate component of stockholders' equity.
	Short-term investments are also comprised of marketable securities related to deferred compensation under the Company’s Deferred Compensation Plan. Mutual funds are the only investments allowed in the Company's Deferred Compensation Plan and the investments are held in a grantor trust formed by the Company. The Company has classified these investments as trading securities as the grantor trust actively manages the asset allocation to match the participants’ notional fund allocations. These securities are recorded at fair market value with unrealized gains and losses included in other income (expense), net.
Certain Risks And Uncertainties [Policy Text Block]	'
	Certain risks and uncertainties
	The Company's products are concentrated in the networking industry, which is characterized by rapid technological advances, changes in customer requirements and evolving regulatory requirements and industry standards. The success of the Company depends on management's ability to anticipate and/or to respond quickly and adequately to technological developments in its industry, changes in customer requirements, or changes in regulatory requirements or industry standards. Any significant delays in the development or introduction of products could have a material adverse effect on the Company's business and operating results.
	The Company relies on a limited number of third parties to manufacture all of its products. If any of the Company's third-party manufacturers cannot or will not manufacture its products in required volumes, on a cost-effective basis, in a timely manner, or at all, the Company will have to secure additional manufacturing capacity. Any interruption or delay in manufacturing could have a material adverse effect on the Company's business and operating results.
Derivatives[Policy Text Block]	'
	Derivative financial instruments
	The Company uses foreign currency forward contracts to manage the exposures to foreign exchange risk related to expected future cash flows on certain forecasted revenue, costs of revenue, operating expenses, and on certain existing assets and liabilities. Foreign currency forward contracts generally mature within five months of inception. Under its foreign currency risk management strategy, the Company utilizes derivative instruments to reduce the impact of currency exchange rate movements on the Company's operating results by offsetting gains and losses on the forward contracts with increases or decreases in foreign currency transactions. The company does not use derivative financial instruments for speculative purposes.
	The Company accounts for its derivative instruments as either assets or liabilities and records them at fair value. Derivatives that are not defined as hedges in the authoritative guidance for derivatives and hedging must be adjusted to fair value through earnings. For derivative instruments that hedge the exposure to variability in expected future cash flows that are designated as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of cumulative other comprehensive income in stockholders' equity and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument is recognized in current earnings. To receive hedge accounting treatment, cash flow hedges must be highly effective in offsetting changes to expected future cash flows on hedged transactions. For derivatives designated as cash flow hedges, changes in the time value are excluded from the assessment of hedge effectiveness and are recognized in earnings.
Concentration Risk, Credit Risk [Policy Text Block]	'
	Concentration of credit risk
	Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and cash equivalents, short-term investments and accounts receivable. The Company believes that there is minimal credit risk associated with the investment of its cash and cash equivalents and short-term investments, due to the restrictions placed on the type of investment that can be entered into under the Company's investment policy. The Company's short-term investments consist of investment-grade securities, and the Company's cash and investments are held and managed by recognized financial institutions.
	The Company's customers are primarily distributors as well as retailers and broadband service providers who sell or distribute the products to a large group of end-users. The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of the Company's customers to make required payments. The Company regularly performs credit evaluations of the Company's customers' financial condition and considers factors such as historical experience, credit quality, age of the accounts receivable balances, geographic or country-specific risks and current economic conditions that may affect customers' ability to pay, and, generally, requires no collateral from its customers. The Company secures credit insurance for certain customers in international and domestic markets.
	As of December 31, 2013 and 2012, Best Buy, Inc. represented 21% and 22% of the Company's total accounts receivable respectively.
	The Company is exposed to credit loss in the event of nonperformance by counterparties to the foreign currency forward contracts used to mitigate the effect of foreign currency exchange rate changes. The Company believes the counterparties for its outstanding contracts are large, financially sound institutions and thus, the Company does not anticipate nonperformance by these counterparties. However, given the recent, unprecedented turbulence in the financial markets, the failure of additional counterparties is possible.
Fair Value of Financial Instruments [Policy Text Block]	'
	Fair value measurements
	The carrying amounts of the Company's financial instruments, including cash equivalents, short-term investments, accounts receivable, and accounts payable approximate their fair values due to their short maturities. Foreign currency forward contracts are recorded at fair value based on observable market data. See Note 13, Fair Value Measurements, of the Notes to Consolidated Financial Statements for disclosures regarding fair value measurements in accordance with the authoritative guidance for fair value measurements and disclosures.
Cost Method Investments [Policy Text Block]	'
	Cost method investments
	As of December 31, 2013 and December 31, 2012, the carrying value of the Company's cost method investments was $1.3 million. These investments are included in other non-current assets in the consolidated balance sheets and are carried at cost, adjusted for any impairment, because the Company does not have a controlling interest and does not have the ability to exercise significant influence over these companies. The Company monitors these investments for impairment on a quarterly basis, and adjusts carrying value for any impairment charges recognized. There were no impairments recognized in the years ended December 31, 2013 and December 31, 2012. Realized gains and losses on these investments are reported in other income (expense), net in the consolidated statements of operations. In the third fiscal quarter of 2012 the Company recognized a gain of $3.1 million on the partial sale of one of its cost method investments.
Allowance for doubtful accounts [Policy Text Block]	'
	Allowance for doubtful accounts
	The Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. The Company regularly performs credit evaluations of its customers' financial condition and considers factors such as historical experience, credit quality, age of the accounts receivable balances, and geographic or country-specific risks and economic conditions that may affect a customer's ability to pay. The allowance for doubtful accounts is reviewed quarterly and adjusted if necessary based on the Company's assessments of its customers' ability to pay. If the financial condition of the Company's customers should deteriorate or if actual defaults are higher than the Company's historical experience, additional allowances may be required, which could have an adverse impact on operating expenses.
Inventory, Policy [Policy Text Block]	'
	Inventories
	Inventories consist primarily of finished goods which are valued at the lower of cost or market, with cost being determined using the first-in, first-out method. The Company writes down its inventories based on estimated excess and obsolete inventories determined primarily by future demand forecasts. At the point of loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.
Property, Plant and Equipment, Policy [Policy Text Block]	'
	Property and equipment, net
	Property and equipment are stated at historical cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets as follows:
	Computer equipment	2 years
	Furniture and fixtures	5 years
	Software	2-5 years
	Machinery and equipment	2-3 years
	Leasehold improvements	Shorter of the lease term or 5 years
	Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated undiscounted future net cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. The carrying value of the asset is reviewed on a regular basis for the existence of facts, both internal and external, that may suggest impairment.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	'
	Goodwill
	Goodwill represents the purchase price over estimated fair value of net assets of businesses acquired in a business combination. Goodwill acquired in a business combination is not amortized, but instead tested for impairment at least annually during the fourth quarter. Should certain events or indicators of impairment occur between annual impairment tests, the Company will perform the impairment test as those events or indicators occur. Examples of such events or circumstances include the following: a significant decline in the Company’s expected future cash flows; a sustained, significant decline in the Company’s stock price and market capitalization; a significant adverse change in the business climate; and slower growth rates.
	Goodwill is tested for impairment at the reporting unit level by first performing a qualitative assessment to determine whether it is more likely than not (that is, a likelihood of more than 50%) that the fair value of the reporting unit is less than its carrying value. The qualitative assessment considers the following factors: macroeconomic conditions, industry and market considerations, cost factors, overall company financial performance, events affecting the reporting units, and changes in the Company's share price. If the reporting unit does not pass the qualitative assessment, then the Company estimates its fair value and compare the fair value with the carrying value of its net assets. If the fair value is greater than the carrying value of its net assets, then no impairment results. If the fair value is less than its carrying value, then it would determine the fair value of the goodwill by comparing the implied fair value to the carrying value of the goodwill in the same manner as if the Company were being acquired in a business combination. Specifically, the Company would allocate the fair value to all of our assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that would calculate the implied fair value of goodwill. If the implied fair value of goodwill is less than the recorded goodwill, an impairment charge would be recorded to earnings in the Consolidated Statements of Operations.
Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]	'
	Intangible assets
	Purchased intangible assets with finite lives are amortized using the straight-line method over the estimated economic lives of the assets, which range from four to ten years. Finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition.
	Purchased intangible assets determined to have indefinite useful lives are not amortized. Indefinite-lived intangible assets are reviewed for impairment at least annually during the fourth quarter and whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Measurement of an impairment loss for indefinite-lived assets that management expects to hold and use is based on the fair value of the asset. Indefinite-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell. The carrying value of the asset is reviewed on a regular basis for the existence of facts, both internal and external, that may suggest impairment.
Standard Product Warranty, Policy [Policy Text Block]	'
	Product warranties
	The Company provides for estimated future warranty obligations at the time revenue is recognized. The Company's standard warranty obligation to its direct customers generally provides for a right of return of any product for a full refund in the event that such product is not merchantable or is found to be damaged or defective. At the time revenue is recognized, an estimate of future warranty returns is recorded to reduce revenue in the amount of the expected credit or refund to be provided to its direct customers. At the time the Company records the reduction to revenue related to warranty returns, the Company includes within cost of revenue a write-down to reduce the carrying value of such products to net realizable value. The Company's standard warranty obligation to its end-users provides for replacement of a defective product for one or more years. Factors that affect the warranty obligation include product failure rates, material usage, and service delivery costs incurred in correcting product failures. The estimated cost associated with fulfilling the Company's warranty obligation to end-users is recorded in cost of revenue. Because the Company's products are manufactured by third-party manufacturers, in certain cases the Company has recourse to the third-party manufacturer for replacement or credit for the defective products. The Company gives consideration to amounts recoverable from its third-party manufacturers in determining its warranty liability.
Revenue Recognition, Policy [Policy Text Block]	'
	Revenue recognition
	Revenue from product sales is generally recognized at the time the product is shipped provided that persuasive evidence of an arrangement exists, title and risk of loss has transferred to the customer, the selling price is fixed or determinable and collection of the related receivable is reasonably assured. Currently, for some of the Company's customers, title passes to the customer upon delivery to the port or country of destination, upon their receipt of the product, or upon the customer's resale of the product. At the end of each fiscal quarter, the Company estimates and defers revenue related to product where title has not transferred. The revenue continues to be deferred until such time that title passes to the customer. The Company assesses collectability based on a number of factors, including general economic and market conditions, past transaction history with the customer, and the creditworthiness of the customer. If the Company determines that collection of the fee is not reasonably assured, then the Company defers the fee and recognizes revenue upon receipt of payment.
	The Company has an insignificant amount of product offerings with multiple elements. The Company's multiple-element product offerings include networking hardware with embedded software, various software subscription services, and support, which are considered separate units of accounting. In general, the networking hardware with embedded software is delivered up front, while the subscription services and support are delivered over the subscription and support period. The Company allocates revenue to the software deliverables and the non-software deliverables (including software deliverables which function together with hardware deliverables to provide the product's essential functionality) based upon their relative selling price. Revenue allocated to each unit of accounting is then recognized when persuasive evidence of an arrangement exists, title and risk of loss has transferred to the customer, the selling price is fixed or determinable and collection of the related receivable is reasonably assured.
	When applying the relative selling price method, the Company determines the selling price for each deliverable using vendor-specific objective evidence ("VSOE") of fair value of the deliverable, or when VSOE of fair value is unavailable, its best estimate of selling price (“ESP”), as the Company has determined it is unable to establish third-party evidence of selling price for the deliverables. In determining VSOE, the Company requires that a substantial majority of the selling prices for a deliverable sold on a stand-alone basis fall within a reasonably narrow pricing range, generally evidenced by approximately 80% of such historical stand-alone transactions falling within +/-15% of the median price. The Company determines ESP for a deliverable by considering multiple factors including, but not limited to, market conditions, competitive landscape, internal costs, gross margin objectives and pricing practices. The objective of ESP is to determine the price at which the Company would transact a sale if the deliverable were sold on a stand-alone basis. The determination of ESP is made through consultation with and formal approval by the Company's management, taking into consideration the go-to-market strategy.
	Certain distributors and retailers generally have the right to return product for stock rotation purposes. Upon shipment of the product, the Company reduces revenue for an estimate of potential future product warranty and stock rotation returns related to the current period product revenue. Management analyzes historical returns, channel inventory levels, current economic trends and changes in customer demand for the Company's products when evaluating the adequacy of the allowance for sales returns, namely warranty and stock rotation returns. Revenue on shipments is also reduced for estimated price protection and sales incentives deemed to be contra-revenue under the authoritative guidance for revenue recognition.
Revenue Recognition, Incentives [Policy Text Block]	'
	Sales incentives
	The Company accrues for sales incentives as a marketing expense if it receives an identifiable benefit in exchange and can reasonably estimate the fair value of the identifiable benefit received; otherwise, it is recorded as a reduction to revenues. As a consequence, the Company records a substantial portion of its channel marketing costs as a reduction of revenue.
	The Company records estimated reductions to revenues for sales incentives at the later of when the related revenue is recognized or when the program is offered to the customer or end consumer.
Shipping and Handling Cost, Policy [Policy Text Block]	'
	Shipping and handling fees and costs
	The Company includes shipping and handling fees billed to customers in net revenue. Shipping and handling costs associated with inbound freight are included in cost of revenue. In cases where the Company gives a freight allowance to the customer for their own inbound freight costs, such costs are appropriately recorded as a reduction in net revenue.
Research and Development Expense, Policy [Policy Text Block]	'
	Research and development
	Costs incurred in the research and development of new products are charged to expense as incurred.
Advertising Costs, Policy [Policy Text Block]	'

Income Tax, Policy [Policy Text Block]	'
	Income taxes
	The Company accounts for income taxes under an asset and liability approach. Under this method, income tax expense is recognized for the amount of taxes payable or refundable for the current year. In addition, deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences resulting from different treatment for tax versus accounting for certain items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets and liabilities, which are included within the consolidated balance sheet. The Company must then assess the likelihood that the Company's deferred tax assets will be recovered from future taxable income and to the extent the Company believes that recovery is not more likely than not, the Company must establish a valuation allowance.
	In the ordinary course of business there is inherent uncertainty in assessing the Company's income tax positions. The Company assesses its tax positions and records benefits for all years subject to examination based on management's evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, the Company records the largest amount of tax benefit with a greater than 50 percent likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit has been recorded in the financial statements. Where applicable, associated interest and penalties have also been recognized as a component of income tax expense.
Earnings Per Share, Policy [Policy Text Block]	'
	Computation of net income per share
	Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the additional dilution from potential issuances of common stock, such as stock issuable pursuant to the exercise of stock options and awards. Potentially dilutive shares are excluded from the computation of diluted net income per share when their effect is anti-dilutive.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	'
	Stock-based compensation
	The Company measures stock-based compensation at the grant date based on the fair value of the award. The fair value of stock options is estimated using the Black-Scholes option pricing model. Estimated compensation cost relating to restricted stock units (“RSUs”) is based on the closing fair market value of the Company’s common stock on the date of grant. The fair value of Employee Stock Purchase Plan (“ESPP”) is based on the 15% discount at purchase, since the price of the shares is determined at the purchase date.
	The compensation expense for equity awards is reduced by an estimate for forfeitures and is recognized over the vesting period of the award under a graded vesting method.  In addition, the Company will recognize an excess benefit from stock-based compensation in equity based on the difference between tax expense computed with consideration of the windfall deduction and without consideration of the windfall deduction. In addition, the Company accounts for the indirect effects of stock-based compensation on the research tax credit and the foreign tax credit in the income statement. See Note 11, Employee Benefit Plans, of the Notes to Consolidated Financial Statements for a further discussion on stock-based compensation.
Comprehensive Income [Policy Text Block]	'
	Comprehensive income
	Comprehensive income consists of net income and other gains and losses affecting stockholder's equity that the Company excluded from net income, including gains and losses related to fair value of short-term investments and the effective portion of cash flow hedges that were outstanding as of the end of the year.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	'
	Foreign currency translation
	The Company's functional currency is the U.S. dollar for all of its international subsidiaries. Foreign currency transactions of international subsidiaries are re-measured into U.S. dollars at the end-of-period exchange rates for monetary assets and liabilities, and historical exchange rates for non-monetary assets. Expenses are re-measured at average exchange rates in effect during each period, except for expenses related to non-monetary assets, which are re-measured at historical exchange rates. Revenue is re-measured at average exchange rates in effect during each period.
