1. Organization and Summary of Significant Accounting Policies | |||||||||
Description of Business | |||||||||
MaxLinear, Inc. (the Company) was incorporated in Delaware in September 2003. The Company is a provider of integrated, radio-frequency and mixed-signal integrated circuits for broadband communication applications whose customers include module makers, original equipment manufacturers, or OEMs, and original design manufacturers, or ODMs, who incorporate the Company’s products in a wide range of electronic devices including cable and terrestrial and satellite set top boxes, DOCSIS data and voice gateways, and hybrid analog and digital televisions. The Company is a fabless semiconductor company focusing its resources on the design, sales and marketing of its products. | |||||||||
Basis of Presentation and Principles of Consolidation | |||||||||
The consolidated financial statements include the accounts of MaxLinear, Inc. and its wholly owned subsidiaries. All intercompany transactions and investments have been eliminated in consolidation. | |||||||||
The functional currency of certain foreign subsidiaries is the local currency. Accordingly, assets and liabilities of these foreign subsidiaries are translated at the current exchange rate at the balance sheet date and historical rates for equity. Revenue and expense components are translated at weighted average exchange rates in effect during the period. Gains and losses resulting from foreign currency translation are included as a component of stockholders’ equity. Foreign currency transaction gains and losses are included in the results of operations and, to date, have not been significant. | |||||||||
Use of Estimates | |||||||||
The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes of the consolidated financial statements. Actual results could differ from those estimates. | |||||||||
Reclassifications | |||||||||
Certain amounts previously included in income (loss) before income taxes have been reclassified to income (loss) from operations to conform to the current period presentation. These amounts related primarily to the impairment of long-lived assets in 2012 and 2011. Such reclassifications did not affect total net revenue, net income (loss), stockholders' equity or cash flows. | |||||||||
Cash and Cash Equivalents | |||||||||
The Company considers all liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents are recorded at cost, which approximates market value. | |||||||||
Accounts Receivable | |||||||||
The Company performs ongoing credit evaluations of its customers and adjusts credit limits based on each customer's credit worthiness, as determined by the Company’s review of current credit information. The Company monitors collections and payments from its customers and maintains an allowance for doubtful accounts based upon its historical experience, its anticipation of uncollectible accounts receivable and any specific customer collection issues that the Company has identified. As of December 31, 2013 and 2012, the Company had recorded an allowance for doubtful accounts of $0.1 million and $0.1 million, respectively. | |||||||||
Inventory | |||||||||
The Company assesses the recoverability of its inventory based on assumptions about demand and market conditions. Forecasted demand is determined based on historical sales and expected future sales. Inventory is stated at the lower of cost or market. Cost approximates actual cost on a first-in, first-out basis and market reflects current replacement cost (e.g. net replacement value) which cannot exceed net realizable value or fall below net realizable value less an allowance for an approximately normal profit margin. The Company reduces its inventory to its lower of cost or market on a part-by-part basis to account for its obsolescence or lack of marketability. Reductions are calculated as the difference between the cost of inventory and its market value based upon assumptions about future demand and market conditions. Once established, these adjustments are considered permanent and are not revised until the related inventory is sold or disposed of. | |||||||||
Investments, Available-for-Sale | |||||||||
The Company classifies all investments as available-for-sale, as the sale of such investments may be required prior to maturity to implement management strategies. These investments are carried at fair value, with unrealized gains and losses reported as accumulated other comprehensive income until realized. The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion, as well as interest and dividends, are included in interest income. Realized gains and losses from the sale of available-for-sale investments, if any, are determined on a specific identification basis and are also included in interest income. | |||||||||
Fair Value of Financial Instruments | |||||||||
The carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses and compensation are considered to be representative of their respective fair value because of the short-term nature of these items. Investment securities, available-for-sale, are carried at fair value. Based on the borrowing rates currently available to the Company for loans with similar terms, the Company believes the fair value of long-term capital lease obligations approximates its carrying value. | |||||||||
Property and Equipment | |||||||||
Property and equipment is carried at cost and depreciated over the estimated useful lives of the assets, ranging from two to five years, using the straight-line method. Leasehold improvements are stated at cost and amortized over the shorter of the estimated useful lives of the assets or the lease term. | |||||||||
Production Masks | |||||||||
Production masks with alternative future uses or discernible future benefits are capitalized and amortized over their estimated useful life of two years. To determine if the production mask has alternative future uses or benefits, the Company evaluates risks associated with developing new technologies and capabilities, and the related risks associated with entering new markets. Production masks that do not meet the criteria for capitalization are expensed as research and development costs. | |||||||||
Impairment of Long-Lived Assets | |||||||||
The Company regularly reviews the carrying amount of its long-lived assets, as well as the useful lives, to determine whether indicators of impairment may exist which warrant adjustments to carrying values or estimated useful lives. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset. Should impairment exist, the impairment loss would be measured based on the excess of the carrying amount of the asset over the asset’s fair value. | |||||||||
Intangible Assets | |||||||||
Technologies acquired or licensed from other companies are capitalized and amortized over the greater of the terms of the agreement, or estimated useful life, not to exceed three years. | |||||||||
Revenue Recognition | |||||||||
Revenue is generated from sales of the Company’s integrated circuits. The Company recognizes revenue when all of the following criteria are met: 1) there is persuasive evidence that an arrangement exists, 2) delivery of goods has occurred, 3) the sales price is fixed or determinable and 4) collectibility is reasonably assured. Title to product transfers to customers either when it is shipped to or received by the customer, based on the terms of the specific agreement with the customer. | |||||||||
Revenue is recorded based on the facts at the time of sale. Transactions for which the Company cannot reliably estimate the amount that will ultimately be collected at the time the product has shipped and title has transferred to the customer are deferred until the amount that is probable of collection can be determined. Items that are considered when determining the amounts that will be ultimately collected are: a customer’s overall creditworthiness and payment history; customer rights to return unsold product; customer rights to price protection; customer payment terms conditioned on sale or use of product by the customer; or extended payment terms granted to a customer. | |||||||||
A portion of the Company’s revenues are generated from sales made through distributors under agreements allowing for pricing credits and/or stock rotation rights of return. Revenues from sales through the Company’s distributors accounted for 29% and 40% of net revenue for the years ended December 31, 2013, and December 31, 2012, respectively. Pricing credits to the Company’s distributors may result from its price protection and unit rebate provisions, among other factors. These pricing credits and/or stock rotation rights prevent the Company from being able to reliably estimate the final sales price of the inventory sold and the amount of inventory that could be returned pursuant to these agreements. As a result, for sales through distributors, the Company has determined that it does not meet all of the required revenue recognition criteria at the time it delivers its products to distributors as the final sales price is not fixed or determinable. | |||||||||
For these distributor transactions, revenue is not recognized until product is shipped to the end customer and the amount that will ultimately be collected is fixed or determinable. Upon shipment of product to these distributors, title to the inventory transfers to the distributor and the distributor is invoiced, generally with 30 day terms. On shipments to the Company’s distributors where revenue is not recognized, the Company records a trade receivable for the selling price as there is a legally enforceable right to payment, relieving the inventory for the carrying value of goods shipped since legal title has passed to the distributor, and records the corresponding gross profit in the consolidated balance sheet as a component of deferred revenue and deferred profit, representing the difference between the receivable recorded and the cost of inventory shipped. Future pricing credits and/or stock rotation rights from the Company’s distributors may result in the realization of a different amount of profit included in the Company’s future consolidated statements of operations than the amount recorded as deferred profit in the Company’s consolidated balance sheets. | |||||||||
The Company records reductions in revenue for estimated pricing adjustments related to price protection agreements with the Company’s end customers in the same period that the related revenue is recorded. Price protection pricing adjustments are recorded at the time of sale as a reduction to revenue and an increase in the Company’s accrued liabilities. The amount of these reductions is based on specific criteria included in the agreements and other factors known at the time. The Company accrues 100% of potential price protection adjustments at the time of sale and does not apply a breakage factor. The Company reverses the accrual for unclaimed price protection amounts as specific programs contractually end and when the Company believes unclaimed amounts are no longer subject to payment and will not be paid. See Note 4 for a summary of the Company's price protection activity. | |||||||||
Stock Repurchase | |||||||||
The Company records the excess of repurchase price over par value to accumulated deficit upon repurchase and retirement of shares of its Class A common stock and Class B common stock in accordance with the accounting standard for equity. | |||||||||
Warranty | |||||||||
The Company generally provides a warranty on its products for a period of one to three years. The Company makes estimates of product return rates and expected costs to replace the products under warranty at the time revenue is recognized based on historical warranty experience and any known product warranty issues. If actual return rates and/or replacement costs differ significantly from these estimates, adjustments to recognize additional cost of net revenue may be required in future periods. At December 31, 2013 and 2012, no accrual for warranty costs was recorded based on the Company’s analysis. | |||||||||
Segment Information | |||||||||
The Company operates in one segment as it has developed, marketed and sold primarily only one class of similar products, integrated radio frequency analog and mixed signal semiconductor solutions for broadband communication applications. | |||||||||
The Company’s chief operating decision-maker is its chief executive officer, who reviews operating results on an aggregate basis and manages the Company’s operations as a single operating segment. | |||||||||
The Company has assessed its products on an individual basis and determined that they are similar based on the following reasons: | |||||||||
• | The Company’s portfolio of products share similar economic characteristics as they have a similar long term business model, operate at gross margins similar to the Company’s consolidated gross margin, and have similar research and development expenses and similar selling, general and administrative expenses; | ||||||||
• | The causes for variation within the Company’s portfolio of products are the same and include factors such as (i) life cycle and price and cost fluctuations, (ii) number of competitors, (iii) extent of product differentiation relative to the Company’s competition, and (iv) the sensitivity to the overall cyclical nature of the semiconductor industry; | ||||||||
• | The Company’s product portfolio and development roadmap is managed by a common Vice President and General Manager, and the technology across products within the portfolio is so similar that the Company’s engineering resources are highly fungible and commonly work across product families; | ||||||||
• | The Company’s integrated circuits all use the same standard CMOS manufacturing processes and provide the same fundamental functionality in the electronics platforms in which they reside; | ||||||||
• | The integrated circuits marketed are sold to one type of customer: manufacturers of wired and wireless communications equipment, which incorporate the Company’s integrated circuits into their electronic products; and | ||||||||
• | All of the Company’s integrated circuits are sold through a centralized sales force and common distributors. | ||||||||
Concentration of Credit Risk and Significant Customers | |||||||||
Financial instruments, which potentially subject the Company to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable. The Company limits its exposure to credit loss by placing its cash with high credit quality financial institutions. At times, such deposits may be in excess of insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. | |||||||||
The Company markets its products and services to manufacturers of wired and wireless communications equipment throughout the world. The Company makes periodic evaluations of the credit worthiness of its customers and does not require collateral for credit sales. | |||||||||

Stock-based Compensation | |||||||||
The Company measures the cost of employee services received in exchange for equity incentive awards, including stock options, employee stock purchase rights, restricted stock units and restricted stock awards based on the grant date fair value of the award. The Company uses the Black-Scholes valuation model to calculate the fair value of stock options and employee stock purchase rights granted to employees. The Company calculates the fair value of restricted stock units and restricted stock awards based on the fair market value of its Class A common stock on the grant date. Stock-based compensation expense is recognized over the period during which the employee is required to provide services in exchange for the award, which is usually the vesting period. The Company recognizes compensation expense over the vesting period using the straight-line method and classifies these amounts in the statements of operations based on the department to which the related employee reports. | |||||||||
The Company accounts for stock options issued to non-employees in accordance with authoritative guidance for equity based payments to non-employees. Stock options issued to non-employees are accounted for at their estimated fair value determined using the Black-Scholes option-pricing model. The fair value of options granted to non-employees is re-measured as they vest, and the resulting increase in value, if any, is recognized as expense during the period the related services are rendered. The Company calculates the fair value of restricted stock units issued to non-employees based on the fair market value of our Class A common stock on the grant date and the resulting stock-based compensation expense is recognized over the period during which the non-employee is required to provide services in exchange for the award, which is usually the vesting period. | |||||||||
Research and Development | |||||||||
Costs incurred in connection with the development of the Company’s technology and future products are charged to research and development expense as incurred. | |||||||||
Income Taxes | |||||||||
The Company provides for income taxes utilizing the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when a judgment is made that is considered more likely than not that a tax benefit will not be realized. A decision to record a valuation allowance results in an increase in income tax expense or a decrease in income tax benefit. If the valuation allowance is released in a future period, income tax expense will be reduced accordingly. | |||||||||
The calculation of tax liabilities involves dealing with uncertainties in the application of complex global tax regulations. The impact of an uncertain income tax position is recognized at the largest amount that is “more likely than not” to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result. | |||||||||
In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company will continue to assess the need for a valuation allowance on the deferred tax asset by evaluating both positive and negative evidence that may exist. Any adjustment to the net deferred tax asset valuation allowance would be recorded in the income statement for the period that the adjustment is determined to be required. | |||||||||
Comprehensive Income (Loss) | |||||||||
Comprehensive income (loss) is defined as the change in equity (net assets) of a business entity during a period from transactions and other events and circumstances from nonowner sources. Other comprehensive income (loss) includes certain changes in equity that are excluded from net income (loss), such as unrealized holding gains and losses on available-for-sale investments, net of tax, and translation gains and losses. | |||||||||
Net Income (Loss) per Share | |||||||||
Basic net income (loss) per share is computed by dividing net income (loss) attributable to the Company by the weighted average number of shares of Class A and Class B common stock outstanding during the period. For diluted net income (loss) per share, net income attributable to the Company is divided by the sum of the weighted average number of shares of Class A and Class B common stock outstanding and the potential number of shares of dilutive Class A and Class B common stock outstanding during the period. | |||||||||
Litigation and Settlement Costs | |||||||||
Legal costs are expensed as incurred. The Company is involved in disputes, litigation and other legal actions in the ordinary course of business. The Company continually evaluates uncertainties associated with litigation and records a charge equal to at least the minimum estimated liability for a loss contingency when both of the following conditions are met: (i) information available prior to issuance of the financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements and (ii) the loss or range of loss can be reasonably estimated. | |||||||||
Recent Accounting Pronouncements | |||||||||
Effective January 1, 2013, the Company adopted the Financial Accounting Standards Board’s standard regarding the reporting of reclassifications out of accumulated other comprehensive income. The new standard requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. | |||||||||
In July 2013, the FASB issued amendments to guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendments require entities to present an unrecognized tax benefit netted against certain deferred tax assets when specific requirements are met. The amended guidance is effective on a prospective basis for the Company beginning in the first quarter of fiscal year 2014. The Company does not expect this amended guidance to significantly impact its consolidated financial statements. |

Net Loss Per Share | ||||||||||||
Net loss per share is computed as required by the accounting standard for earnings per share, or EPS. Basic EPS is calculated by dividing net loss by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted EPS is computed by dividing net loss by the weighted-average number of common shares outstanding for the period and the weighted-average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method. For purposes of this calculation, common stock options, restricted stock units and restricted stock awards are considered to be common stock equivalents and are only included in the calculation of diluted EPS when their effect is dilutive. | ||||||||||||
The Company has two classes of stock outstanding, Class A common stock and Class B common stock. The economic rights of the Class A common stock and Class B common stock, including rights in connection with dividends and payments upon a liquidation or merger are identical, and the Class A common stock and Class B common stock will be treated equally, identically and ratably, unless differential treatment is approved by the Class A common stock and Class B common stock, each voting separately as a class. The Company computes basic earnings per share by dividing net loss by the weighted average number of shares of Class A and Class B common stock outstanding during the period. For diluted earnings per share, the Company divides net loss by the sum of the weighted average number of shares of Class A and Class B common stock outstanding and the potential number of shares of dilutive Class A and Class B common stock outstanding during the period. | ||||||||||||

As of December 31, 2013, the Company held 12 corporate and government debt securities with an aggregate fair value of $19.5 million that were in an unrealized loss position for less than 12 months. The gross unrealized losses of $0.01 million at December 31, 2013 represent temporary impairments on corporate and government debt securities related to multiple issuers, and were primarily caused by fluctuations in U.S. interest rates. The Company has determined that the gross unrealized losses on these securities at December 31, 2013 are temporary in nature. The Company evaluates securities for other-than-temporary impairment on a quarterly basis. Impairment is evaluated considering numerous factors, and their relative significance varies depending on the situation. Factors considered include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the issuer, and the Company's intent and ability to hold the security in order to allow for an anticipated recovery in fair value. | ||||||||||||||||
All of the Company’s long-term available-for-sale securities were due between 1 and 2 years as of December 31, 2013. | ||||||||||||||||
The fair values of the Company’s financial instruments are the amounts that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants and are recorded using a hierarchal disclosure framework based upon the level of subjectivity of the inputs used in measuring assets and liabilities. The levels are described below: | ||||||||||||||||
Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. | ||||||||||||||||
Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. | ||||||||||||||||
Level 3: Unobservable inputs are used when little or no market data is available. | ||||||||||||||||
The Company classifies its financial instruments within Level 1 or Level 2 of the fair value hierarchy on the basis of valuations using quoted market prices or alternate pricing sources and models utilizing market observable inputs, respectively. The Company’s money market funds were valued based on quoted prices for the specific securities in an active market and were therefore classified as Level 1. The government and corporate debt securities have been valued on the basis of valuations provided by third-party pricing services, as derived from such services’ pricing models. The pricing services may use a consensus price which is a weighted average price based on multiple sources or mathematical calculations to determine the valuation for a security, and have been classified as Level 2. The Company reviews Level 2 inputs and fair value for reasonableness and the values may be further validated by comparison to independent pricing sources. In addition, the Company reviews third-party pricing provider models, key inputs and assumptions and understands the pricing processes at its third-party providers in determining the overall reasonableness of the fair value of its Level 2 financial instruments. As of December 31, 2013 and 2012, the Company has not made any adjustments to the prices obtained from its third party pricing providers. The Company held no Level 3 financial instruments as of December 31, 2013 and 2012. | ||||||||||||||||

During May 2009, the Company entered into two lease agreements for office facilities in Carlsbad, CA. One lease commenced on June 1, 2009 and expires on January 22, 2014. The second lease commenced on September 1, 2009 and expires on March 31, 2014. The lease which expires on March 31, 2014 has an option to extend the lease beyond the initial term for three years. The terms of these leases provide for rental payments on a monthly basis with periodic rent escalations over the term of the lease. As disclosed in the Company's Current Report on Form 8-K, filed with the SEC on December 20, 2013, the Company entered into a lease for approximately 45,000 square feet of office space in Carlsbad, California. The lease has a term of five years, six months, commencing on the later of March 27, 2014 or the date five days following substantial completion of certain tenant improvements. The Company expects to relocate its current operations in Carlsbad, California to the new facility beginning in the second quarter of 2014. During January 2010, the Company entered into a five-year noncancelable operating lease agreement for a research and development facility in Irvine, CA. The lease is subject to rent holidays and rent increases and commenced in April 2010 with an option to extend the lease for an additional five years. During February and August 2011 and October 2012, the Company entered into amendments to its existing operating lease agreement for a research and development facility in Irvine, CA. The amended operating lease calls for an expansion in the amount of space occupied and an extension to May 2016. The Company recognizes rent expense on a straight-line basis over the lease period and has accrued for rent expense incurred but not paid. In addition, incentives were granted, including discounted rental payments and inducements. As such, these allowances have been recorded as deferred rent and these items are being recognized as reductions to rental expense on a straight-line basis over the term of the lease. | |||||||||||||
At December 31, 2013, future minimum annual payments under the non-cancelable operating leases, other obligations and inventory purchase obligations are as follows: | |||||||||||||

On July 17, 2012, Silicon Labs filed a complaint for patent infringement against the Company in United States District Court for the Southern District of California. The Silicon Labs complaint asserts that a wide range of the Company’s products infringe a single Silicon Labs patent, U.S. Patent No. 7,035,607, or the ‘607 patent. The ‘607 patent is related to several of the nineteen (19) patents on which the Company filed a declaratory judgment action against Silicon Labs. The Company has filed counterclaims for infringement on three (3) patents owned by the Company – United States Patent Nos. 7,362,178; 8,198,940; and 7,778,613. The July 17, 2012 litigation and May 13, 2012 litigation were related by Court order on July 23, 2012. | |||||||||||||
On July 30, 2012, Silicon Labs filed a declaratory judgment complaint in United States District Court for the Western District of Texas against the Company seeking an order that Silicon Labs’ products do not infringe the three (3) patents owned by the Company asserted as counterclaims in the second Southern District of California action. On January 17, 2013, the Court granted the Company’s Motion to Dismiss for Lack of Jurisdiction and ordered dismissal of the Texas action. | |||||||||||||
On May 16, 2013, the Company filed a complaint for patent infringement against Silicon Labs in the United States District Court for the Southern District of California. The complaint asserts a wide range of Silicon Labs' products infringe five (5) patents owned by the Company - United States Patent Nos. 8,374,568; 8,374,569; 8,374,570; 8,253,488; and 8,427,232. | |||||||||||||
As disclosed in the Company's Current Report on Form 8-K, as filed with the SEC on October 4, 2013, the Company entered into a settlement agreement with Silicon Labs, that resolved all currently outstanding patent litigation between the Company and Silicon Labs that is described above. Under the terms of the settlement agreement, each party agreed to dismiss all currently outstanding litigation against the other party with prejudice. In connection with the settlement agreement, each party granted the other party a worldwide, non-exclusive, royalty-free, and fully paid-up license to its patent portfolio. The scope of the patent licenses is limited to existing products that were subject to the litigation. The settlement agreement releases each party and their respective direct and indirect customers from past infringement liability with respect to the products subject to the litigation. Each party agreed not to bring any patent infringement lawsuit against the other party for a period of three years from the date of the settlement agreement. The parties agreed that neither the execution and delivery of the settlement agreement nor any provision of the settlement agreement constituted an admission by either the Company or Silicon Labs of liability, infringement, or validity of any licensed patents. | |||||||||||||
The Company evaluated the settlement agreement as a multiple element arrangement which required the payment consideration to be allocated to the identifiable elements based on relative fair value. As a result, the Company determined that the $1.25 million payment to Silicon Labs should be expensed and recorded in selling, general and administrative expense in the year ended December 31, 2013. The Company had not previously recorded an accrual for loss contingencies associated with Silicon Labs litigation as it was not able to determine that an unfavorable outcome was probable or reasonably possible or determine that the amount or range of any possible loss was reasonably estimable given the early stage of the discovery process in prior quarters. | |||||||||||||
Export Compliance Matter | |||||||||||||
In the first quarter of 2012, the Company determined that it may have taken actions that could constitute facilitation (within the meaning of applicable sanctions and export control laws) of shipments of foreign produced products to Iran or taken other actions that may be in violation of U.S. export control and economic sanctions laws. Specifically, certain of the Company’s tuner products, which are foreign produced and not subject to U.S. export controls, were included in set-top converter boxes produced by set-top box manufacturers in Asia to permit conversion of digital television signals to analog signals in international markets, including Iran, using the DVB-T, or Digital Video Broadcasting – Terrestrial, broadcast standard. The DVB-T standard is used in most of Europe, Asia (excluding China), Australia, and Africa as well as in parts of the Middle East, including Iran. While the underlying shipment of the Company’s tuners into Iran by foreign manufacturers of these set-top boxes may have been lawful, the Company may have violated applicable sanctions and export control laws without the proper U.S. Government authorization. | |||||||||||||
The Company initially identified these potential violations internally, rather than as a result of a third-party audit or government investigation, and upon learning of these potential violations, the Company’s audit committee promptly retained outside counsel to conduct a review of the Company’s sanctions and export control compliance. On February 7, 2012, the Company made voluntary initial filings with the Office of Foreign Assets Control of the United States Department of the Treasury, or OFAC, and with the Bureau of Industry and Security of the United States Department of Commerce, or BIS, notifying these regulatory agencies that the Company was conducting a review of export control matters and that the Company would submit any supplemental voluntary self-disclosures once the Company’s internal review was complete. The initial stage of the review was concluded in March 2012. Subsequently, the Company also learned that the Company was not in full compliance with BIS’s deemed export rule which requires, in some circumstances, that the companies obtain a deemed export license from BIS for employment of certain foreign nationals even if, as was the Company’s situation, the Company had obtained an H1-B visa prior to employing the individual. The Company has now applied for such license with respect to the subject employee. | |||||||||||||
In connection with its March 2012 review, the Company’s audit committee determined that the Company’s management team lacked sufficient familiarity with and understanding of export control and sanctions laws and their applicability to the Company’s products and services. The Company’s audit committee concluded that the Company’s management team did not intentionally or knowingly violate applicable sanctions and export control laws. | |||||||||||||
The Company submitted final voluntary disclosures to OFAC on June 1, 2012 and BIS on June 15, 2012 and July 11, 2012. On September 27, 2012, OFAC closed out the Company’s Voluntary Self Disclosure with the issuance of a cautionary letter, and no monetary or other penalty was imposed against the Company. On November 6, 2012, BIS closed out the Company’s Voluntary Self Disclosure with the issuance of a warning letter, which means that no monetary or other penalty was imposed against the Company. | |||||||||||||
In the year ended December 31, 2012, the Company reduced its previously recorded estimates of OFAC and BIS penalties and fines by $0.9 million. At December 31, 2012, the Company had no liability recorded for this matter. As a result of increased awareness relative to U.S. export control and economic sanction laws relating to the sale of its products, the Company has implemented additional export control compliance management oversight and has undertaken remedial measures to reduce the risk of similar events occurring in the future. | |||||||||||||
Warranties and Indemnifications | |||||||||||||
In connection with the sale of products in the ordinary course of business, the Company often makes representations affirming, among other things, that its products do not infringe on the intellectual property rights of others, and agree to indemnify customers against third-party claims for such infringement. Further, the Company’s certificate of incorporation and bylaws require the Company to indemnify its officers and directors against any action that may arise out of their services in that capacity, and the Company has also entered into indemnification agreements with respect to all of its directors and certain controlling persons. As of December 31, 2013, no expenses were incurred under such provisions. As of December 31, 2012, the Company incurred expenses of $0.3 million under such provisions related to a previously disclosed export compliance matter. | |||||||||||||
Other Matters | |||||||||||||
In addition, from time to time, the Company is subject to threats of litigation or actual litigation in the ordinary course of business, some of which may be material. Other than the CrestaTech litigation described above, the Company believes that there are no other currently pending matters that, if determined adversely to the Company, would have a material effect on its business or that would not be covered by its existing liability insurance maintained by the Company. |

Common Stock | |||||||||||||
At December 31, 2013, the Company had 500 million authorized shares of Class A common stock and 500 million authorized shares of Class B common stock. Holders of the Company’s Class A and Class B common stock have identical voting rights, except that holders of Class A common stock are entitled to one vote per share and holders of Class B common stock are entitled to ten votes per share with respect to transactions that would result in a change of control of the Company or that relate to the Company’s equity incentive plans. In addition, holders of Class B common stock have the exclusive right to elect 2 members of the Company’s Board of Directors, each referred to as a Class B Director. The shares of Class B common stock are not publicly traded. Each share of Class B common stock is convertible at any time at the option of the holder into one share of Class A common stock and in most instances automatically converts upon sale or other transfer. | |||||||||||||
Stock Repurchase | |||||||||||||
In the year ended December 31, 2012, the Company’s board of directors and the audit committee of the Company’s board of directors approved the repurchase and retirement of 1.2 million shares of the Company’s Class A common stock and the repurchase and retirement of 1.0 million shares of the Company’s Class B common stock. The Company effected the repurchases pursuant to a stock repurchase agreement. The per share repurchase price for both Class A and Class B shares repurchased was the closing price of the Company’s Class A common stock in trading on the New York Stock Exchange on the date of the agreement. The aggregate repurchase price was $12.1 million. There were no stock repurchases in the year ended December 31, 2013. | |||||||||||||
Other than the transactions disclosed above, the Company’s board of directors has not authorized any stock repurchase program, and the Company has no current plans to effect any open-market purchases of its Class A common stock or other repurchases of its Class B common stock from two of its shareholders. | |||||||||||||
Exchange Offer | |||||||||||||
In May 2012, the Company completed an offer to exchange (the “Exchange Offer”) for restricted stock units (RSUs), certain outstanding options to purchase shares of the Company’s Class A common stock and shares of the Company’s Class B common stock. Pursuant to the terms and conditions of the Exchange Offer, the Company accepted for exchange options to purchase 1.3 million shares of the Company’s Class A common stock and 0.6 million shares of the Company’s Class B common stock. All surrendered options were cancelled, and immediately thereafter, the Company issued a total of 1.0 million restricted stock units in exchange therefor, pursuant to the terms of the Exchange Offer. The Company accounted for the Exchange Offer as a modification of the original options as required by the accounting standard for stock-based compensation. The total Exchange Offer stock-based compensation is $7.3 million, including the incremental value attributed to the modified options of $1.8 million, which will be recognized over the vesting period of the new RSUs. | |||||||||||||
Employee Benefit Plans | |||||||||||||
At December 31, 2013, the Company had stock-based compensation awards outstanding under the following plans: the 2004 Stock Plan, the 2010 Equity Incentive Plan and the 2010 Employee Stock Purchase Plan. Upon the closing of the initial public offering in March 2010, all stock awards are issued under the 2010 Equity Incentive Plan and are no longer issued under the 2004 Stock Plan. | |||||||||||||
2010 Equity Incentive Plan | |||||||||||||
The 2010 Plan provides for the grant of incentive stock options, non-statutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights, performance-based stock awards, and other forms of equity compensation, or collectively, stock awards. The aggregate number of shares of Class A common stock that may be issued pursuant to stock awards under the 2010 Plan will increase by any shares subject to stock options or other awards granted under the 2004 Stock Plan that expire or otherwise terminate without having been exercised in full and shares issued pursuant to awards granted under the 2004 Stock Plan that are forfeited to or repurchased by the Company. In addition, the number of shares of common stock reserved for issuance will automatically increase on the first day of each fiscal year, equal to the lesser of: 2.6 million shares of the Company’s Class A common stock; four percent (4%) of the outstanding shares of the Company’s Class A common stock and Class B common stock on the last day of the immediately preceding fiscal year; or such lesser amount as the Company’s board of directors may determine. Options granted will generally vest over a four year period and the term can be from seven to ten years. | |||||||||||||
2010 Employee Stock Purchase Plan | |||||||||||||
The ESPP authorizes the issuance of shares of the Company’s Class A common stock pursuant to purchase rights granted to the Company’s employees. The number of shares of the Company’s common stock reserved for issuance will automatically increase on the first day of each fiscal year, equal to the least of: 1.0 million shares of the Company’s Class A common stock; one and a quarter percent (1.25%) of the outstanding shares of the Company’s Class A common stock and Class B common stock on the first day of the fiscal year; or such lesser amount as may be determined by our board of directors or a committee appointed by our board of directors to administer the ESPP. The ESPP is implemented through a series of offerings of purchase rights to eligible employees. Under the ESPP, the Company may specify offerings with a duration of not more than 27 months, and may specify shorter purchase periods within each offering. Each offering will have one or more purchase dates on which shares of the Company’s common stock will be purchased for employees participating in the offering. An offering may be terminated under certain circumstances. Generally, all regular employees, including executive officers, employed by the Company may participate in the ESPP and may contribute up to 15% of their earnings for the purchase of the Company’s common stock under the ESPP. Unless otherwise determined by the Company’s board of directors, Class A common stock will be purchased for accounts of employees participating in the ESPP at a price per share equal to the lower of (a) 85% of the fair market value of a share of the Company’s Class A common stock on the first date of an offering or (b) 85% of the fair market value of a share of the Company’s Class A common stock on the date of purchase. | |||||||||||||
Bonus Plan | |||||||||||||
In April 2012, the Company's compensation committee amended its Executive Incentive Bonus Plan to, among other things, permit the settlement of awards under the plan in the form of shares of its Class A common stock. In May 2013, the Company's compensation committee amended its Executive Incentive Bonus Plan to permit the settlement of awards under the plan in any combination of cash or shares of its Class A common stock. For the 2012 performance period, actual awards under the Executive Incentive Bonus Plan were settled in Class A common stock issued under its 2010 Equity Incentive Plan with the number of shares issuable to plan participants determined based on the closing sales price of the Company's Class A common stock as determined in trading on the New York Stock Exchange on May 3, 2013. Additionally, the Company settled all bonus awards for all other employees for the 2012 performance period in shares of its Class A common stock. The Company issued 0.8 million shares of its Class A common stock for the 2012 performance period upon settlement of the bonus awards on May 3, 2013. | |||||||||||||
At December 31, 2013, an accrual of $5.1 million was recorded for bonus awards for employees for the 2013 performance period, which the Company intends to settle in shares of its Class A common stock issued under its 2010 Equity Incentive Plan, as amended, with the number of shares issuable to plan participants determined based on the closing sales price of the Company’s Class A common stock as determined in trading on the New York Stock Exchange at a date to be determined. The Company's compensation committee retains discretion to effect payment in cash, stock, or a combination of cash and stock. | |||||||||||||
Stock-Based Compensation | |||||||||||||
Stock-based compensation expense is classified in the consolidated statements of operations based on the department to which the related employee reports. The Company recognized stock-based compensation in the statements of operations as follows: | |||||||||||||

The total unrecognized compensation cost related to unvested stock options as of December 31, 2013 was $3.8 million, and the weighted average period over which these equity awards are expected to vest is 2.62 years. The total unrecognized compensation cost related to unvested restricted stock units and restricted stock awards as of December 31, 2013 was $21.4 million, and the weighted average period over which these equity awards are expected to vest is 2.49 years. | |||||||||||||
The Company records equity instruments issued to non-employees as expense at their fair value over the related service period as determined in accordance with the authoritative guidance and periodically revalues the equity instruments as they vest. Stock-based compensation expense related to non-employee consultants totaled $0.2 million, $0.8 million and $0.2 million for 2013, 2012 and 2011, respectively. | |||||||||||||
Stock Options | |||||||||||||
The Company uses the Black-Scholes valuation model to calculate the fair value of stock options and employee stock purchase rights granted to employees.

Volatility | 39.24 - 41.58% | 46.60 - 55.74% | 45.70 - 72.84% | ||||||||||
The risk-free interest rate assumption was based on the United States Treasury’s rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. The weighted-average expected life of options was calculated using the simplified method as prescribed by guidance provided by the SEC. This decision was based on the lack of historical data due to the Company’s limited number of stock option exercises under the 2010 Equity Incentive Plan. In addition, due to the Company’s limited historical data, the estimated volatility incorporates the historical volatility of comparable companies whose share prices are publicly available as well as the historical volatility of the Company. | |||||||||||||

Net deferred tax assets | $ | 166 | $ | — | ||||||||
At December 31, 2013, the Company had federal and state tax net operating loss carryforwards of approximately $27.7 million and $24.0 million, respectively. These amounts include share-based compensation for federal and state of $7.8 million and $3.8 million, that will be recorded to contributed capital when realized. The federal and state tax loss carryforwards will begin to expire in 2026 and 2019, respectively, unless previously utilized. | ||||||||||||
At December 31, 2013, the Company had federal and state tax credit carryforwards of approximately $8.3 million and $8.7 million, respectively. The federal tax credit carryforward will begin to expire in 2024, unless previously utilized. The state tax credits do not expire. In addition, the Company has federal alternative minimum tax credit carryforwards of $0.2 million that can be carried forward indefinitely. | ||||||||||||
Pursuant to Internal Revenue Code Section 382 and 383, use of the Company’s net operating loss and credit carryforwards may be limited if a cumulative change in ownership of more than 50% occurs within a three-year period. The Company has had two changes of ownership in April and November of 2004 resulting in an annual net operating loss and credit limitation. The annual limitations will not cause a loss of net operating loss or credit carryforwards. Additional limitations on the use of these tax attributes could occur in the event of possible disputes arising in examinations from various taxing authorities. | ||||||||||||
The Company evaluated its net deferred income taxes, which included an assessment of the cumulative income or loss over the prior three-year period and future periods, to determine if a valuation allowance is required. After considering its recent history of losses and management’s expectations of additional near-term losses, the Company recorded a valuation allowance on its net federal deferred tax assets, with a corresponding charge to its income tax provision of approximately $6.7 million during 2011. During 2013 and 2012, the Company maintained a valuation allowance against all of its federal and state deferred tax assets as realization of such assets does not meet the more-likely-than-not threshold required under accounting guidelines. The Company will continue to assess the need for a valuation allowance on the deferred tax assets by evaluating positive and negative evidence that may exist. | ||||||||||||
At December 31, 2013, the Company’s unrecognized tax benefits totaled $5.5 million, $4.6 million of which, if recognized at a time when the valuation allowance no longer exists, would affect the effective tax rate. The Company will recognize interest and penalties related to unrecognized tax benefits as a component of income tax expense. At December 31, 2013, the Company had no accrual for interest and penalties. The Company does not expect any significant increases or decreases to its unrecognized tax benefits within twelve months. | ||||||||||||

The Company is subject to federal and California income tax in the United States and is also subject to income tax in certain other foreign tax jurisdictions. At December 31, 2013, the Company is no longer subject to federal, California or foreign income tax examinations for the years before 2010, 2009, and 2007, respectively. However, to the extent allowed by law, the tax authorities may have the right to examine prior periods where net operating losses or tax credits were generated and carried forward, and make adjustments up to the amount of the net operating loss or credit carryforward amount. | ||||||||||||
At December 31, 2013, the Company was under examination by the federal tax authorities for the tax years 2010 and 2011. This examination closed in January 2014. The impact of any adjustments has been reflected in 2013. At December 31, 2012, the Company was under examination by the California tax authorities for the tax years 2008 and 2009. This examination closed during the three months ended March 31, 2013 with no adjustment to taxable income. | ||||||||||||
On January 2, 2013, the American Taxpayer Relief Act of 2012 was enacted. The Act included several provisions related to corporate income tax including the reinstatement of the credit for qualified research and development. The credit was reinstated for years beginning after January 1, 2012. |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | ' | ||||||||
Description of Business | ' | ||||||||
Description of Business | |||||||||
MaxLinear, Inc. (the Company) was incorporated in Delaware in September 2003. The Company is a provider of integrated, radio-frequency and mixed-signal integrated circuits for broadband communication applications whose customers include module makers, original equipment manufacturers, or OEMs, and original design manufacturers, or ODMs, who incorporate the Company’s products in a wide range of electronic devices including cable and terrestrial and satellite set top boxes, DOCSIS data and voice gateways, and hybrid analog and digital televisions. The Company is a fabless semiconductor company focusing its resources on the design, sales and marketing of its products. | |||||||||
Basis of Presentation and Principles of Consolidation | ' | ||||||||
Basis of Presentation and Principles of Consolidation | |||||||||
The consolidated financial statements include the accounts of MaxLinear, Inc. and its wholly owned subsidiaries. All intercompany transactions and investments have been eliminated in consolidation. | |||||||||
The functional currency of certain foreign subsidiaries is the local currency. Accordingly, assets and liabilities of these foreign subsidiaries are translated at the current exchange rate at the balance sheet date and historical rates for equity. Revenue and expense components are translated at weighted average exchange rates in effect during the period. Gains and losses resulting from foreign currency translation are included as a component of stockholders’ equity. Foreign currency transaction gains and losses are included in the results of operations and, to date, have not been significant. | |||||||||
Use of Estimates | ' | ||||||||
Use of Estimates | |||||||||
The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes of the consolidated financial statements. Actual results could differ from those estimates. | |||||||||
Cash and Cash Equivalents | ' | ||||||||
Cash and Cash Equivalents | |||||||||
The Company considers all liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents are recorded at cost, which approximates market value. | |||||||||
Accounts Receivable | ' | ||||||||
Accounts Receivable | |||||||||
The Company performs ongoing credit evaluations of its customers and adjusts credit limits based on each customer's credit worthiness, as determined by the Company’s review of current credit information. The Company monitors collections and payments from its customers and maintains an allowance for doubtful accounts based upon its historical experience, its anticipation of uncollectible accounts receivable and any specific customer collection issues that the Company has identified. As of December 31, 2013 and 2012, the Company had recorded an allowance for doubtful accounts of $0.1 million and $0.1 million, respectively. | |||||||||
Inventory | ' | ||||||||
Inventory | |||||||||
The Company assesses the recoverability of its inventory based on assumptions about demand and market conditions. Forecasted demand is determined based on historical sales and expected future sales. Inventory is stated at the lower of cost or market. Cost approximates actual cost on a first-in, first-out basis and market reflects current replacement cost (e.g. net replacement value) which cannot exceed net realizable value or fall below net realizable value less an allowance for an approximately normal profit margin. The Company reduces its inventory to its lower of cost or market on a part-by-part basis to account for its obsolescence or lack of marketability. Reductions are calculated as the difference between the cost of inventory and its market value based upon assumptions about future demand and market conditions. Once established, these adjustments are considered permanent and are not revised until the related inventory is sold or disposed of. | |||||||||
Investment, Available-for-Sale | ' | ||||||||
Investments, Available-for-Sale | |||||||||
The Company classifies all investments as available-for-sale, as the sale of such investments may be required prior to maturity to implement management strategies. These investments are carried at fair value, with unrealized gains and losses reported as accumulated other comprehensive income until realized. The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion, as well as interest and dividends, are included in interest income. Realized gains and losses from the sale of available-for-sale investments, if any, are determined on a specific identification basis and are also included in interest income. | |||||||||
Fair Value of Financial Instruments | ' | ||||||||
Fair Value of Financial Instruments | |||||||||
The carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses and compensation are considered to be representative of their respective fair value because of the short-term nature of these items. Investment securities, available-for-sale, are carried at fair value. Based on the borrowing rates currently available to the Company for loans with similar terms, the Company believes the fair value of long-term capital lease obligations approximates its carrying value. | |||||||||
Property and Equipment | ' | ||||||||
Property and Equipment | |||||||||
Property and equipment is carried at cost and depreciated over the estimated useful lives of the assets, ranging from two to five years, using the straight-line method. Leasehold improvements are stated at cost and amortized over the shorter of the estimated useful lives of the assets or the lease term. | |||||||||
Production Masks | ' | ||||||||
Production Masks | |||||||||
Production masks with alternative future uses or discernible future benefits are capitalized and amortized over their estimated useful life of two years. To determine if the production mask has alternative future uses or benefits, the Company evaluates risks associated with developing new technologies and capabilities, and the related risks associated with entering new markets. Production masks that do not meet the criteria for capitalization are expensed as research and development costs. | |||||||||
Impairment of Long-Lived Assets | ' | ||||||||
Impairment of Long-Lived Assets | |||||||||
The Company regularly reviews the carrying amount of its long-lived assets, as well as the useful lives, to determine whether indicators of impairment may exist which warrant adjustments to carrying values or estimated useful lives. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset. Should impairment exist, the impairment loss would be measured based on the excess of the carrying amount of the asset over the asset’s fair value. | |||||||||
Intangible Assets | ' | ||||||||
Intangible Assets | |||||||||
Technologies acquired or licensed from other companies are capitalized and amortized over the greater of the terms of the agreement, or estimated useful life, not to exceed three years. | |||||||||
Revenue Recognition | ' | ||||||||
Revenue Recognition | |||||||||
Revenue is generated from sales of the Company’s integrated circuits. The Company recognizes revenue when all of the following criteria are met: 1) there is persuasive evidence that an arrangement exists, 2) delivery of goods has occurred, 3) the sales price is fixed or determinable and 4) collectibility is reasonably assured. Title to product transfers to customers either when it is shipped to or received by the customer, based on the terms of the specific agreement with the customer. | |||||||||
Revenue is recorded based on the facts at the time of sale. Transactions for which the Company cannot reliably estimate the amount that will ultimately be collected at the time the product has shipped and title has transferred to the customer are deferred until the amount that is probable of collection can be determined. Items that are considered when determining the amounts that will be ultimately collected are: a customer’s overall creditworthiness and payment history; customer rights to return unsold product; customer rights to price protection; customer payment terms conditioned on sale or use of product by the customer; or extended payment terms granted to a customer. | |||||||||
A portion of the Company’s revenues are generated from sales made through distributors under agreements allowing for pricing credits and/or stock rotation rights of return. Revenues from sales through the Company’s distributors accounted for 29% and 40% of net revenue for the years ended December 31, 2013, and December 31, 2012, respectively. Pricing credits to the Company’s distributors may result from its price protection and unit rebate provisions, among other factors. These pricing credits and/or stock rotation rights prevent the Company from being able to reliably estimate the final sales price of the inventory sold and the amount of inventory that could be returned pursuant to these agreements. As a result, for sales through distributors, the Company has determined that it does not meet all of the required revenue recognition criteria at the time it delivers its products to distributors as the final sales price is not fixed or determinable. | |||||||||
For these distributor transactions, revenue is not recognized until product is shipped to the end customer and the amount that will ultimately be collected is fixed or determinable. Upon shipment of product to these distributors, title to the inventory transfers to the distributor and the distributor is invoiced, generally with 30 day terms. On shipments to the Company’s distributors where revenue is not recognized, the Company records a trade receivable for the selling price as there is a legally enforceable right to payment, relieving the inventory for the carrying value of goods shipped since legal title has passed to the distributor, and records the corresponding gross profit in the consolidated balance sheet as a component of deferred revenue and deferred profit, representing the difference between the receivable recorded and the cost of inventory shipped. Future pricing credits and/or stock rotation rights from the Company’s distributors may result in the realization of a different amount of profit included in the Company’s future consolidated statements of operations than the amount recorded as deferred profit in the Company’s consolidated balance sheets. | |||||||||
The Company records reductions in revenue for estimated pricing adjustments related to price protection agreements with the Company’s end customers in the same period that the related revenue is recorded. Price protection pricing adjustments are recorded at the time of sale as a reduction to revenue and an increase in the Company’s accrued liabilities. The amount of these reductions is based on specific criteria included in the agreements and other factors known at the time. The Company accrues 100% of potential price protection adjustments at the time of sale and does not apply a breakage factor. The Company reverses the accrual for unclaimed price protection amounts as specific programs contractually end and when the Company believes unclaimed amounts are no longer subject to payment and will not be paid. See Note 4 for a summary of the Company's price protection activity. | |||||||||
Stock Repurchase | ' | ||||||||
Stock Repurchase | |||||||||
The Company records the excess of repurchase price over par value to accumulated deficit upon repurchase and retirement of shares of its Class A common stock and Class B common stock in accordance with the accounting standard for equity. | |||||||||
Warranty | ' | ||||||||
Warranty | |||||||||
The Company generally provides a warranty on its products for a period of one to three years. The Company makes estimates of product return rates and expected costs to replace the products under warranty at the time revenue is recognized based on historical warranty experience and any known product warranty issues. If actual return rates and/or replacement costs differ significantly from these estimates, adjustments to recognize additional cost of net revenue may be required in future periods. At December 31, 2013 and 2012, no accrual for warranty costs was recorded based on the Company’s analysis. | |||||||||
Segment Information | ' | ||||||||
Segment Information | |||||||||
The Company operates in one segment as it has developed, marketed and sold primarily only one class of similar products, integrated radio frequency analog and mixed signal semiconductor solutions for broadband communication applications. | |||||||||
The Company’s chief operating decision-maker is its chief executive officer, who reviews operating results on an aggregate basis and manages the Company’s operations as a single operating segment. | |||||||||
The Company has assessed its products on an individual basis and determined that they are similar based on the following reasons: | |||||||||
• | The Company’s portfolio of products share similar economic characteristics as they have a similar long term business model, operate at gross margins similar to the Company’s consolidated gross margin, and have similar research and development expenses and similar selling, general and administrative expenses; | ||||||||
• | The causes for variation within the Company’s portfolio of products are the same and include factors such as (i) life cycle and price and cost fluctuations, (ii) number of competitors, (iii) extent of product differentiation relative to the Company’s competition, and (iv) the sensitivity to the overall cyclical nature of the semiconductor industry; | ||||||||
• | The Company’s product portfolio and development roadmap is managed by a common Vice President and General Manager, and the technology across products within the portfolio is so similar that the Company’s engineering resources are highly fungible and commonly work across product families; | ||||||||
• | The Company’s integrated circuits all use the same standard CMOS manufacturing processes and provide the same fundamental functionality in the electronics platforms in which they reside; | ||||||||
• | The integrated circuits marketed are sold to one type of customer: manufacturers of wired and wireless communications equipment, which incorporate the Company’s integrated circuits into their electronic products; and | ||||||||
• | All of the Company’s integrated circuits are sold through a centralized sales force and common distributors. | ||||||||
Concentration of Credit Risk and Significant Customers | ' | ||||||||
Concentration of Credit Risk and Significant Customers | |||||||||
Financial instruments, which potentially subject the Company to concentrations of credit risk, consist primarily of cash and cash equivalents and accounts receivable. The Company limits its exposure to credit loss by placing its cash with high credit quality financial institutions. At times, such deposits may be in excess of insured limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. | |||||||||
The Company markets its products and services to manufacturers of wired and wireless communications equipment throughout the world. The Company makes periodic evaluations of the credit worthiness of its customers and does not require collateral for credit sales. | |||||||||

Stock-based Compensation | ' | ||||||||
Stock-based Compensation | |||||||||
The Company measures the cost of employee services received in exchange for equity incentive awards, including stock options, employee stock purchase rights, restricted stock units and restricted stock awards based on the grant date fair value of the award. The Company uses the Black-Scholes valuation model to calculate the fair value of stock options and employee stock purchase rights granted to employees. The Company calculates the fair value of restricted stock units and restricted stock awards based on the fair market value of its Class A common stock on the grant date. Stock-based compensation expense is recognized over the period during which the employee is required to provide services in exchange for the award, which is usually the vesting period. The Company recognizes compensation expense over the vesting period using the straight-line method and classifies these amounts in the statements of operations based on the department to which the related employee reports. | |||||||||
The Company accounts for stock options issued to non-employees in accordance with authoritative guidance for equity based payments to non-employees. Stock options issued to non-employees are accounted for at their estimated fair value determined using the Black-Scholes option-pricing model. The fair value of options granted to non-employees is re-measured as they vest, and the resulting increase in value, if any, is recognized as expense during the period the related services are rendered. The Company calculates the fair value of restricted stock units issued to non-employees based on the fair market value of our Class A common stock on the grant date and the resulting stock-based compensation expense is recognized over the period during which the non-employee is required to provide services in exchange for the award, which is usually the vesting period. | |||||||||
Research and Development Expense | ' | ||||||||
Research and Development | |||||||||
Costs incurred in connection with the development of the Company’s technology and future products are charged to research and development expense as incurred. | |||||||||
Income Taxes | ' | ||||||||
Income Taxes | |||||||||
The Company provides for income taxes utilizing the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of the Company’s assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when a judgment is made that is considered more likely than not that a tax benefit will not be realized. A decision to record a valuation allowance results in an increase in income tax expense or a decrease in income tax benefit. If the valuation allowance is released in a future period, income tax expense will be reduced accordingly. | |||||||||
The calculation of tax liabilities involves dealing with uncertainties in the application of complex global tax regulations. The impact of an uncertain income tax position is recognized at the largest amount that is “more likely than not” to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result. | |||||||||
In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company will continue to assess the need for a valuation allowance on the deferred tax asset by evaluating both positive and negative evidence that may exist. Any adjustment to the net deferred tax asset valuation allowance would be recorded in the income statement for the period that the adjustment is determined to be required. | |||||||||
Comprehensive Income (Loss) | ' | ||||||||
Comprehensive Income (Loss) | |||||||||
Comprehensive income (loss) is defined as the change in equity (net assets) of a business entity during a period from transactions and other events and circumstances from nonowner sources. Other comprehensive income (loss) includes certain changes in equity that are excluded from net income (loss), such as unrealized holding gains and losses on available-for-sale investments, net of tax, and translation gains and losses. | |||||||||
Net Income (Loss) per Share | ' | ||||||||
Net Income (Loss) per Share | |||||||||
Basic net income (loss) per share is computed by dividing net income (loss) attributable to the Company by the weighted average number of shares of Class A and Class B common stock outstanding during the period. For diluted net income (loss) per share, net income attributable to the Company is divided by the sum of the weighted average number of shares of Class A and Class B common stock outstanding and the potential number of shares of dilutive Class A and Class B common stock outstanding during the period. | |||||||||
Settlement and Legal Costs | ' | ||||||||
Litigation and Settlement Costs | |||||||||
Legal costs are expensed as incurred. The Company is involved in disputes, litigation and other legal actions in the ordinary course of business. The Company continually evaluates uncertainties associated with litigation and records a charge equal to at least the minimum estimated liability for a loss contingency when both of the following conditions are met: (i) information available prior to issuance of the financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements and (ii) the loss or range of loss can be reasonably estimated. | |||||||||
Recent Accounting Pronouncements | ' | ||||||||
Recent Accounting Pronouncements | |||||||||
Effective January 1, 2013, the Company adopted the Financial Accounting Standards Board’s standard regarding the reporting of reclassifications out of accumulated other comprehensive income. The new standard requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. | |||||||||
In July 2013, the FASB issued amendments to guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The amendments require entities to present an unrecognized tax benefit netted against certain deferred tax assets when specific requirements are met. The amended guidance is effective on a prospective basis for the Company beginning in the first quarter of fiscal year 2014. The Company does not expect this amended guidance to significantly impact its consolidated financial statements. |
