Summary of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	Basis of Presentation and Consolidation
	The Company prepared its consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”). The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary in the United Kingdom, established in February 2011. All significant intercompany accounts and transactions have been eliminated in consolidation.
	Change in Fiscal Year End
	Effective January 1, 2013, the Company changed its reporting period from a calendar year ending on December 31 of each year to a 52- or 53-week fiscal year that ends on the last Saturday in December. Fiscal year 2013 was a 52-week fiscal year ended on December 28, 2013, and each quarter was a 13-week quarter.
	Use of Estimates
	The preparation of consolidated financial statements in conformity with GAAP requires management to make certain 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 periods. On an ongoing basis, the Company evaluates its estimates, including but not limited to those related to revenue recognition, provision for doubtful accounts, warranty reserve, excess and obsolete inventory write-downs, stock-based compensation expense, depreciable lives, and income taxes. The Company bases its estimates on historical experience, projections for future performance and other assumptions that it believes to be reasonable under the circumstances. Actual results could differ materially from those estimates.
	Initial Public Offering and Conversion of Preferred Stock
	In June 2013, the Company completed its initial public offering (the “IPO”), in which 7,762,500 shares of its common stock were sold at a public offering price of $19.00 per share. The Company sold 5,512,500 shares of common stock, inclusive of 1,012,500 shares of common stock sold upon the exercise in full of the overallotment option by the underwriters. The Company received proceeds of $93.4 million, net of underwriting discounts and commissions of $7.3 million and other offering expenses of approximately $4.0 million. In addition, certain selling stockholders sold 2,250,000 shares of common stock at a public offering price of $19.00 per share. The Company did not receive any proceeds from the sales of shares by the selling stockholders. In connection with its IPO, all of the Company’s then-outstanding redeemable convertible preferred stock was converted into 8.1 million shares of common stock.
	Follow-On Public Offering
	On October 28, 2013, the Company completed its follow-on public offering, in which 5,100,000 shares of its common stock were sold at a public offering price of $38.50 per share. The Company sold 300,000 shares of common stock, for which the Company received proceeds of $10.2 million, net of underwriting discounts and commissions of $0.5 million and other offering expenses of approximately $0.8 million. In addition, the Company’s selling stockholders sold 4,800,000 shares of common stock, which included 293,718 shares of common stock issued upon the exercise of options by certain selling stockholders, with an aggregate exercise price of $1.3 million, at a public offering price of $38.50 per share. The Company did not receive any proceeds from the sale of shares by the selling stockholders.
	Reverse Stock Split
	Effective May 20, 2013, the Company completed a one-for-three reverse stock split, as approved by its Board of Directors (the “Board”). All shares and per share amounts set forth herein give effect to this reverse stock split.
	Foreign Currency Transactions
	The Company uses the U.S. dollar as its functional currency. Foreign currency assets and liabilities are remeasured into U.S. dollars using the end-of-period exchange rates except for nonmonetary assets and liabilities, which are remeasured using historical exchange rates. Expenses are remeasured using an average exchange rate for the respective period. Gains or losses from foreign currency transactions are included in other expense, net. Foreign currency transaction gains and losses have not been significant to the consolidated financial statements for all periods presented.
	Cash Equivalents and Marketable Securities
	All highly liquid marketable securities with original or remaining maturities of less than three months at the date of purchase are considered to be cash equivalents. Marketable securities are generally classified as available-for-sale for use in current operations, if required, and are reported at fair value, with unrealized gains and losses, net of tax, presented as a separate component of stockholders’ equity under accumulated other comprehensive income. All realized gains and losses and unrealized losses resulting from declines in fair value that are other than temporary are recorded in other expense, net in the period of occurrence. The Company uses the specific identification method to determine the realized gains and losses on investments. For all investments in marketable securities, the Company assesses whether the impairment is other than temporary. If the fair value of a security is less than its amortized cost basis, an impairment is considered other than temporary if (i) the Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of its entire amortized cost basis, or (ii) the Company does not expect to recover the entire amortized cost of the security. If an impairment is considered other than temporary based on condition (i), the entire difference between the amortized cost and the fair value of the security is recognized in earnings. If an impairment is considered other than temporary based on condition (ii), the amount representing credit losses, defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis of the security, will be recognized in earnings, and the amount relating to all other factors will be recognized in other comprehensive income. The Company evaluates both qualitative and quantitative factors such as duration and severity of the unrealized losses, credit ratings, default and loss rates of the underlying collateral, structure and credit enhancements to determine if a credit loss may exist.
	Fair Value of Financial Instruments
	The Company records its financial assets and liabilities at fair value. The accounting guidance for fair value provides a framework for measuring fair value, clarifies the definition of fair value, and expands disclosures regarding fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:
	Level 1 – Quoted prices in active markets for identical assets or liabilities.
	Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	The Company recognizes transfers among Level 1, Level 2 and Level 3 classifications as of the actual date of the events or change in circumstances that caused the transfers.
	The Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and accrued liabilities have carrying amounts which approximate fair value due to the short-term maturity of these instruments.
	Accounts Receivable
	Accounts receivable, which represent trade accounts receivable from both channel partners and direct customers, are recorded at the invoiced amounts and do not bear interest. The Company extends credit to its customers in the normal course of business and performs ongoing credit evaluations of its customers. The Company generally requires no collateral from its customers. The Company establishes an allowance for doubtful accounts for estimated losses resulting from the customer’s inability to make payments. Management determines the collectability of specific customer accounts by their past transaction history. If financial conditions of the Company’s customers were to deteriorate, adversely affecting their ability to make payments, additional allowances would be required. Estimates for allowance for doubtful accounts are charged to operating expenses and a credit to a valuation allowance. As of December 28, 2013 and December 31, 2012, the Company had not recorded an allowance for doubtful accounts.
	Concentrations
	The Company operates in highly competitive and rapidly changing markets that could negatively impact the Company’s operating results. A number of components that meet the Company’s manufacturing requirements are available only from single source suppliers. In addition, the Company relies on one contract manufacturer to manufacture substantially all of its products. The inability of its single source suppliers and contract manufacturer to provide the Company with adequate supplies of high-quality components and products could cause a delay in order fulfillment, which could adversely affect the Company’s revenue, cost of sales and operating results.
	Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash, cash equivalents, investments and accounts receivable. The Company places the majority of its cash, cash equivalents and investments with a limited number of major financial institutions in the United States that management believes are creditworthy. Such deposits may exceed the insured limits provided on them. The Company mitigates credit risk associated with its accounts receivable by performing ongoing credit evaluations of its customers and establishes an allowance for doubtful accounts for estimated losses based on management’s assessment of the collectability of customer accounts. No end-user customer accounted for 10% of more of total accounts receivable.
	The Company sells its products primarily through channel partners, including distributors and resellers, and occasionally directly to end-user customers. For fiscal 2013, 2012 and 2011, no end-user customer accounted for 10% or more of revenue.
	Customers that represented more than 10% of revenue and accounts receivable are the following:

		2013			2012			2011

	Inventory is valued at the lower of cost computed on a first-in, first-out basis, or market value. The Company writes down inventory in excess of forecasted demand over a certain period. In these cases, inventory is reduced to estimated realizable value based on historical usage and expected demand. At the point of inventory write-down, 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. Inherent in the Company’s estimates of market value in determining inventory valuation are estimates related to economic trends, future demand for the Company’s products, and technical obsolescence of products. The Company uses a contract manufacturer to provide manufacturing services for its products. During the normal course of business, in order to manage manufacturing lead times and help ensure adequate component supply, the Company enters into agreements with the contract manufacturer that either allow them to procure inventory based upon criteria as defined by the Company, or establish the parameters defining the Company’s requirements. A portion of the Company’s reported purchase commitments arising from these agreements consists of non-cancelable commitments. The Company records a liability for firm, non-cancelable and unconditional purchase commitments for quantities in excess of its future demand forecasts consistent with the valuation of the Company’s excess and obsolete inventory.
	In fiscal 2013, the Company recognized a $0.8 million net inventory benefit within cost of revenue which included the sale of previously written-down inventory of $1.5 million. The Company recorded inventory write-downs of $1.5 million and $3.2 million in fiscal 2012 and fiscal 2011, respectively, as a component of cost of revenue.
	Property and Equipment
	Property and equipment are stated at cost and depreciated using the straight–line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the lesser of the useful life of these improvements or the remaining term of the lease. Maintenance and repairs are charged to operations as incurred.
	The useful lives of the property and equipment are as follows:
	Furniture and fixtures	5 years
	Software	3 to 5 years
	Equipment and machinery	1.5 to 3 years
	Leasehold improvements	Shorter of lease term or estimated useful life
	Research and Development and Software Development Costs
	Research and development costs are expensed as incurred, except for certain software development costs. To-date, software development costs qualifying for capitalization have been insignificant. Accordingly, the Company has not capitalized any software development costs.
	Impairment of Long-Lived Assets
	The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the anticipated future net undiscounted cash flows to the related assets’ carrying values.
	If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the projected discounted future net cash flows arising from the asset. No assets were determined to be impaired during any of the periods presented.
	Revenue Recognition
	The Company generates product revenue from sales of traffic visibility solutions to channel partners and direct customers as well as services revenue from sales of maintenance and support contracts and other billable services. Most of the Company’s products are hardware appliances containing software components that function together to deliver the essential functionality of the solution. The Company typically delivers products and services in a single transaction. The deliverables consist of traffic visibility solutions, maintenance and support, and other billable services. The Company’s typical arrangement includes the sale of one or multiple products that include first year maintenance and support as well as standard warranty. Other arrangements consist of the sale of products bundled with additional maintenance and support or a renewal of maintenance and support contracts. Billable services are billed in advance or when service is provided and performed as requested by customers. Under maintenance and support contracts, services are provided as needed by customers over the fixed arrangement term. The Company does not grant its customers a general right of return or any refund terms, except to two of the Company’s distributors that have a general right of return and in that case, revenue is deferred until sell-through has occurred. Revenue is reported net of rebates, discounts and any other sales incentives.
	The Company recognizes revenue when (1) persuasive evidence of an arrangement exists, (2) delivery has occurred or services have been rendered, (3) sales price is fixed or determinable and (4) collectability is reasonably assured.
When sales arrangements contain multiple elements and software and non-software components that function together to deliver the products’ essential functionality, the Company allocates revenue to each element based on a selling price hierarchy: vendor-specific objective evidence (“VSOE”) if available, third-party evidence (“TPE”) of the selling price if VSOE is not available, or best estimated selling prices (“ESP”) if neither VSOE nor TPE is available.
When the Company enters in arrangements to provide more than one product or service (“multiple deliverables”), these arrangements are evaluated to determine if the multiple elements consist of more than one unit of accounting and can be separated accordingly. Based on separation criteria under the guidance, deliverables in multiple element arrangements can be segregated into separate units of accounting if they have value to the customer on a standalone basis. If deliverables can be separated into individual units of accounting, then the arrangement consideration is allocated among deliverables based on their relative selling price. Revenue from each deliverable is recognized when all requirements are met for that specific deliverable. If deliverables cannot be separated into separate units of accounting, then the arrangement will be accounted for as a single unit of accounting and revenue will be recognized when all requirements are met for all deliverables within the arrangement. The Company has established VSOE for maintenance and support contracts since the majority of selling prices fall within a narrow range when sold separately. TPE is not used since this information is not widely available in the market and we do not consider our products to be similar to or interchangeable with our competitors’ products in standalone sales to similarly situated customers. For deliverables with no established VSOE, the Company determines the standalone selling price for such deliverables by establishing ESP, which incorporates historical selling prices, the effect of market conditions, gross margin objectives and pricing practices, as well as entity specific factors. The Company monitors and evaluates ESP on a regular basis to ensure that changes in circumstances are accounted for in a timely manner.
Services revenue is recognized ratably over the contractual support period, which is typically one year and can be up to five years.
In accordance with contractual provisions, the Company may offer cooperative marketing funds based on a fixed dollar percentage of product sales to certain of its channel partners or to fund specific marketing activities for these partners. The Company records such amounts as a reduction to revenue or, if the Company has evidence of fair value of the separable and identifiable benefit received, as marketing expense.
Revenue is recorded net of sales taxes. Costs of products not yet recognized as revenue are deferred and included as a component of prepaid expenses and other current assets in the consolidated balance sheets. As of December 28, 2013 and December 31, 2012, deferred product costs were $0.9 million and $0.6 million, respectively.
Shipping and Handling Charges
Shipping and handling costs are recorded in cost of revenue in the period products are shipped to customers.
Warranty
Beginning on February 1, 2011, the Company began providing five-year warranties on its products against defects in manufacturing. Prior to February 1, 2011, the Company provided a one-year warranty on its products. The Company accrues for potential liability claims as a component of cost of product revenue based on historical trends of product failure rates and the expected material and labor costs to provide warranty services. The accrued warranty balance is reviewed periodically for adequacy and is included in accrued liabilities and other liabilities, non-current on the consolidated balance sheets.
Stock-Based Compensation
Stock-based compensation expense related to stock-based transactions, including employee and director awards, as well as employee stock purchase plan purchase rights (“ESPP purchase rights”), is measured and recognized in the consolidated financial statements based on fair value of the award on the grant date. The fair value of option awards and ESPP purchase rights is estimated using the Black-Scholes option-pricing model. This model requires assumptions including the market value of the Company’s common stock, expected volatility, expected term of the award, expected dividend yield and risk-free interest rate. Expected term for stock option awards is determined based on the mid-point of the vest period and the contractual period of each option award due to the Company’s limited historical stock option exercise data. Expected volatility is established based on the historical volatility of the common stock of a peer group of publicly traded companies. The stock-based compensation expense, net of estimated forfeitures, is recognized on a graded-vesting basis over the requisite service periods of the awards, unless a performance-based condition exists. Expense for performance-based awards are recognized when the issuance of the underlying awards are probable. Expense for consultant awards are measured based on the fair value on the vest date. Expenses related to the option grants to consultants that have not been vested as of the reporting date are marked to market until the earlier of the commitment or the completion of the underlying performance. The Company estimates a forfeiture rate to calculate the stock-based compensation for its stock-based awards based on an analysis of its historical experience, analysis of employee turnover and other related factors.
Advertising Costs
Expenses related to advertising of products are charged to sales and marketing expense as incurred. For all periods presented, advertising expenses were insignificant.
Deferred Offering Costs
Deferred offering costs, consisting of legal, accounting and filing fees related to the IPO or the follow-on public offering, were capitalized as other assets and offset against the proceeds received upon the completion of each offering. As of December 28, 2013 and December 31, 2012, the Company had capitalized zero and $2.2 million, respectively, of deferred offering costs within other assets on its consolidated balance sheets.
Income Taxes
The Company is subject to U.S. federal income taxes as well as state taxes. In addition, the Company is subject to taxes in the foreign jurisdictions where it operates.
Prior to the LLC Conversion in May 2013, the Company was a Delaware limited liability company that passed through income and losses to its members. As a result, the Company was not subject to any U.S. federal or state income taxes as the related tax consequences were reported by the individual members.
Effective upon the completion of the LLC Conversion, the Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in its financial statements or tax returns. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carry forwards. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized. Accordingly, the Company assessed the need for a valuation allowance based on the ASC 740 more-likely-than-not realization threshold criterion. Consideration was given to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considered, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods, experience with operating loss and tax credit carryforwards expiring, and tax planning alternatives. Significant judgment was required to determine whether a valuation allowance was necessary and the amount of such valuation allowance, if appropriate.
The Company applies the authoritative accounting guidance prescribing a threshold and measurement attribute for the financial recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more-likely-than-not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the tax liability as the largest amount that is more-likely-than-not to be realized upon ultimate settlement. The Company also accounts for any related interest and penalty charges as a component of income taxes.
Comprehensive (Loss) Income
Comprehensive (loss) income is defined as a change in equity of a business enterprise during a period, resulting from transactions from non-owner sources. Comprehensive (loss) income comprises all components of net (loss) income and all components of other comprehensive income within stockholders’ equity. The Company’s other comprehensive income includes unrealized gains and losses from its available-for-sale securities that are not considered other-than-temporarily impaired.
Earnings Per Share
Basic net (loss) income per share attributable to common stockholders is calculated by dividing the net (loss) income attributable to common stock holders by the weighted-average number of common stock outstanding for the period.
Diluted net income per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock outstanding during the period, including options, restricted stock units (“RSUs”) and ESPP purchase rights. The computation of diluted net income does not assume conversion or exercise of potentially dilutive securities that would have an anti-dilutive effect on earnings. The dilutive effect of outstanding options is computed using the treasury stock method. In periods when the Company has incurred a net loss, potential dilutive common securities outstanding have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive.
Prior to the conversion of its redeemable convertible Series A preferred stock (the “Series A preferred stock”) to common stock, effective June 17, 2013, the Company applied the two-class method for calculating and presenting earnings per share as the Series A preferred stock was considered a participating security due to the rights of cumulative preferred return. Participating securities are defined as securities that participate in dividends with common units according to a pre-determined formula or a contractual obligation to share in the income of the entity. Under the two-class method, net (loss) income is allocated between common stock and other participating securities based on their participating rights. Accordingly, earnings allocated or distributed to the Series A preferred stock as well as the related number of outstanding shares of the Series A preferred stock have been excluded from the computation of basic and diluted net (loss) income per share attributable to common stockholders.
Dilutive securities that were subject to the Company’s IPO were excluded from the Company’s diluted net (loss) income per share calculation for the periods before the close of the Company’s IPO in June 2013.
Recent Accounting Pronouncements
In March 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update requiring an entity to release into net income the entire amount of a cumulative translation adjustment related to its investment in a foreign entity when as a parent it either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets within a foreign entity. This accounting standard update will be effective prospectively for the Company beginning in the first quarter of fiscal 2014. The Company does not expect the adoption of this accounting standard update to have a material impact on its consolidated financial statements.
In July 2013, the FASB issued a new accounting standard update that requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the consolidated balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. Early adoption or a retrospective application is permitted. The Company is required to adopt this new standard on a prospective basis in the first quarter of fiscal 2014. The Company does not expect the adoption of this accounting standard update to have a material impact on its consolidated financial statements.

	On July 2, 2013, the Company entered into a sublease agreement to lease 105,664 square feet of office space, located in Santa Clara, California, with a term of 51 months from January 2014 through March 2018, for an aggregate net base rent of $10.7 million. In addition to the monthly base rent, the Company is responsible for payment of certain operating expenses, including utilities and real estate taxes. The Company is using the leased space as its worldwide corporate headquarters. In addition, the Company leases office space for its former headquarters and its United Kingdom subsidiary under non-cancelable operating leases that expire at various times through December 2017.
	The Company had an option to extend the lease on its former headquarters in Milpitas, California from June 2016 to June 2019, as well as an early termination option which allowed the Company to terminate this lease in June 2014 by providing a written notice and an early termination fee of $250,000 at least 180 days prior to the early termination date. On November 12, 2013, the Company exercised its early termination option and paid the early termination fee of $250,000.

	Revolving Line of Credit
	The Company’s bank line of credit with Silicon Valley Bank, which provided for borrowings of up to $10.0 million, expired in July 2013. There were no borrowings outstanding under the credit facility as of December 28, 2013 and December 31, 2012. The Company was in compliance with the covenants under this credit facility prior to the expiration of the facility.
	Legal Proceedings
	From time to time, the Company may become involved in legal proceedings arising in the ordinary course of business. The Company is not currently a party to any legal proceedings the outcome of which, if determined adversely to the Company, would individually or in the aggregate be expected to have a material adverse effect on its business, operating results, financial condition or cash flows.
	Indemnification Obligations
	Under the indemnification provisions of its standard sales related contracts, the Company agrees to defend its customers against third-party claims asserting infringement of certain intellectual property rights, which may include patents, copyrights, trademarks, or trade secrets, and to pay judgments entered on such claims. The Company’s exposure under these indemnification provisions is generally limited to the total amount paid by its customer under the agreement. However, certain agreements include indemnification provisions that could potentially expose the Company to losses in excess of the amount received under the agreement. The Company has not incurred any costs as a result of such indemnifications and has not accrued any liabilities related to such obligations in the consolidated financial statements. In addition, the Company indemnifies its officers, directors, and certain key employees while they are serving in good faith in their company capacities. To date, there have been no claims under any indemnification provisions. The fair values of these obligations are not material as of each balance sheet date presented.

Performance Unit Plan	'
	7. Performance Unit Plan
	In fiscal 2009, the Company adopted the 2009 Performance Unit Plan (the “2009 Plan”). The 2009 Plan was not an equity plan and was intended to provide an incentive payment to employees, consultants and Board members by providing payment based on the appreciation in value of the Company at the time of a change in control event, such as a business acquisition, merger or an IPO (each performance unit a “PUP”). PUPs did not constitute ownership units or interests of the Company.
	The distribution amount was defined as the difference between the redemption value of the units received at the time of the change of control and the base value of the PUP, which was $0.15 as determined by the Board at each award date. While the distributable amount may be satisfied in either cash or stock at the time of a change in control, the Company elected to make such distribution in cash.
	Under existing accounting guidance, the compensation expense associated with the 2009 Plan is not required to be reflected in the consolidated financial statements until Change of Control is deemed probable. Accordingly, the Company had not recorded any liabilities or compensation expense associated with the PUPs in its consolidated financial statements until the period in which a change of control occurred. Accordingly, the Company recorded compensation and related payroll tax expenses of $20.4 million in its consolidated financial statements in fiscal 2013, for the 1,057,772 PUPs vested upon the completion of the IPO on June 17, 2013. No related compensation expense was recorded in fiscal 2012 and 2011. The 2009 Plan was terminated in June 2013, in connection with the completion of the IPO.

	8. Preferred Stock and Stockholders’ Equity (Members’ Deficit)
	LLC Conversion
	On May 31, 2013, the Company converted from a Delaware limited liability company into a Delaware corporation and changed the Company’s name from Gigamon LLC to Gigamon Inc. Effective May 31, 2013, all of the Company’s outstanding common units and preferred units were converted into shares of common stock and preferred stock. Immediately following the LLC Conversion, certain entities affiliated with Highland Capital Partners that held the Company’s Series A preferred stock were merged with and into the Company, and the entities affiliated with Highland Capital Partners that merged with and into the Company received preferred stock in exchange for their equity interests. Further, in connection with the LLC Conversion, Gigamon Systems LLC, the holder of all of the Company’s outstanding common units prior to the LLC Conversion, exchanged all of the interests that it held in the Company for 16,851,635 shares of the common stock of Gigamon Inc. In addition, all outstanding options to purchase shares in Gigamon Systems LLC were substituted for fully vested options to purchase 448,349 shares of the Company’s common stock, at a weighted average exercise price of $0.02 per share, for which the Company recognized related stock-based compensation expense of $8.5 million in fiscal 2013. Additionally, the Company recorded a net adjustment to deferred income tax asset of $14.8 million and reclassified $24.0 million from accumulated deficit to additional paid-in capital.
	Redeemable Convertible Series A Preferred Units
	The LLC Agreement authorized the Company to issue 8,109,848 Series A preferred units (“Series A”) at no par value. Upon the LLC Conversion, all of the then-outstanding Series A were converted into shares of Series A preferred stock. Furthermore, in connection with the closing of the Company’s IPO, all of the Company’s then-outstanding shares of Series A preferred stock were converted into shares of common stock on June 17, 2013 (the “Series A Conversion”). As of December 28, 2013 and December 31, 2012, the Company had zero and 8,109,847 Series A units outstanding, respectively.
	The rights, privileges and restrictions of Series A units as set forth in the LLC Agreement as in effect prior to the LLC Conversion are summarized as follows:
	Voting
	Each unit of Series A had voting rights equal to an equivalent number of common units into which it was convertible and voted together as one class with the common units.
	Liquidation
	Upon a liquidation or a deemed liquidation event, the Company was obligated to distribute the net proceeds or assets available for distribution, whether in cash or in other property, to the holders of Series A and common units as follows:
		•		First, to the holders of Series A on a pari passu basis, and
		•		Next, to the holders of common units, pro rata in proportion to the number of common units held by such holders.
	A merger or consolidation of the Company into another entity in which the members of the Company would own less than 50% of the voting stock/units of the surviving company or the sale or transfer of substantially all of the assets would be deemed a liquidation of the Company.
	Conversion
	Conversion was either at the option of the holder or was automatic upon the written consent of the requisite Series A Preferred Holders. “Requisite Series A Preferred Holders” was defined as holders of a majority of the Series A units then issued and outstanding, voting as a separate class.
	Each Series A unit was convertible into a common unit by dividing $2.81 by the conversion price in effect. The initial conversion price of $2.81 was subject to adjustments for subdivisions or combinations of common units, reclassification, exchange and substitution and dilutive issuances. As of December 31, 2012, the conversion price in effect was the same as the issuance price. In connection with the LLC Conversion, the Series A units were converted into shares of Series A preferred stock at a ratio of 1-to-1.
	Redemption
	The holders of Series A units were entitled to elect to require the Company to purchase all of the outstanding Series A, after January 20, 2015, at $2.81 per unit plus accrued preferred return at 8% per annum, payable in three equal annual installments. Prior to the redemption upon the completion of the IPO, the Company was accreting to the January 20, 2015 redemption value of $33.5 million. For fiscal 2013, 2012 and 2011, the Company recorded $1.0 million, $2.1 million and $2.0 million, respectively, for the accretion of the Series A units to their redemption value using the effective interest method. As redemption of Series A units was outside the control of the Company, all units have been presented outside of Members’ deficit in the Company’s consolidated balance sheets and consolidated statements of redeemable convertible preferred units and stockholders’ equity (members’ deficit).
	The Company initially recorded the Series A units at their issuance price net of issuance costs, which represented the carrying value. The difference between the initial carrying value of Series A units and their total redemption value was accreted from the issuance date through the first redemption date, January 20, 2015, using the effective interest rate method. The Company recorded accretion of issuance costs of $56,000, $121,000 and $119,000, respectively, for fiscal 2013, 2012 and 2011.
	Preferred Stock
	The Company has authorized 20,000,000 shares of undesignated preferred stock, $0.0001 par value per share. As of December 28, 2013 and December 31, 2012, the Company had no shares of preferred stock issued or outstanding.
	Common Units
	Prior to the LLC Conversion, the Company had 33,333,333 common units authorized. Each holder of common units was entitled to one vote for each common unit held. Upon the LLC Conversion, all of the then-outstanding common units were converted into shares of common stock. As of December 28, 2013 and December 31, 2012, the Company had zero and 17,300,005 common units outstanding, respectively.
	Common Stock
	The Company has authorized 1,000,000,000 shares of common stock, $0.0001 par value per share. Each holder of common stock is entitled to one vote for each share of common stock held. Cumulative voting for the election of directors is not provided in the Company’s amended and restated certificate of incorporation. The Company’s common stock is not entitled to preemptive rights, and is not subject to conversion, redemption or sinking fund provisions. Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of common stock are entitled to receive dividends out of funds legally available if the Board, in its discretion, determines to issue dividends and then only at the times and in the amounts that the Board may determine.
	As of December 28, 2013, the Company had 31,151,723 shares of common stock issued and outstanding. The Company had zero shares of common stock authorized, issued or outstanding as of December 31, 2012.
	Treasury Stock
	As of December 28, 2013 and December 31, 2012, the Company had 8,109,848 shares of treasury stock outstanding, with a carrying value of $12.5 million, or $1.35 per share, within stockholders’ equity (members’ deficit) on its consolidated financial statements. The treasury stock was repurchased in fiscal 2010 pursuant to a purchase and redemption agreement and does not have any restrictions imposed by state law.
	Equity Award Plans
	Unit Option Plan
	In March 2012, the Company adopted the 2012 Unit Option Plan (the “Option Plan”). The Option Plan authorized the Company to grant options and RSUs, up to a maximum of 3,300,505 shares, to employees, members and consultants of the Company. The Option Plan was terminated in connection with the Company’s IPO but will continue to govern the terms and conditions of outstanding awards granted thereunder. Prior to its termination, the Option Plan authorized the Company to grant options and RSUs up to a maximum of 4,967,172 units to employees, directors and consultants of the Company.
	The following table summarizes the activity under the Option Plan prior to its termination (in shares):

	Transferred to 2013 Equity Incentive Plan upon termination			(532,708	)
	Shares available for future grant at December 28, 2013			—
	Under the Option Plan, stock options granted to new hires are generally subject to a four-year vesting period whereby options become 25% vested on the first anniversary from the grant date and then ratably monthly thereafter through the end of the vesting period. Vested options may be exercised up to ten years from the vesting commencement date, as defined in the Option Plan. Vested but unexercised options, under the Option Plan, expire 30 days after termination of employment with the Company. Prior to the IPO, vesting of certain options under the Option Plan was also subject to the completion of the IPO (the “IPO Stock Options”).
	2013 Equity Incentive Plan
	In May 2013, the Company adopted the 2013 Equity Incentive Plan (the “2013 Equity Plan”). All authorized but unissued shares of the Company’s Option Plan were added to the 2013 Equity Plan’s authorized pool in June 2013. The Company is authorized to issue up to a maximum of 2,929,481 shares of common stock for future issuance, plus up to an additional 4,967,172 shares upon termination of awards under the Option Plan. In addition, the 2013 Equity Plan is subject to increase annually on the first day of each of the Company’s fiscal years beginning with fiscal 2014, by an amount equal to the least of (i) 1,464,740 shares, (ii) 5% of the outstanding shares of common stock as of the last day of the immediately preceding fiscal year, or (iii) such other amount as determined by the Board. Vested but unexercised options, under the 2013 Equity Plan, expire three months after termination of service with the Company.
	The 2013 Equity Plan permits the grant of stock options, stock appreciation rights, restricted stock, RSUs, performance units and performance shares to employees, directors and consultants of the Company.
	Employee Stock Purchase Plan
	In conjunction with the completion of its IPO, the Company adopted the 2013 Employee Stock Purchase Plan (the “ESPP”). Under the ESPP, 439,422 shares of the Company’s common stock are authorized for future issuance. The number of authorized shares under the ESPP is subject to increase on an annual basis. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to plan limitations. The ESPP provides for a 24-month offering period comprised of four purchase periods of approximately six months. Employees are able to purchase shares at 85% of the lower of the market value of the Company’s common stock (i) at the date of commencement of the offering period or (ii) at the last day of the purchase period. The offering periods are scheduled to start on the first trading day on or after May 15 and November 15 of each year, except for the first offering period, which commenced on the first trading day upon the completion of the Company’s IPO, or June 12, 2013, and ends on August 17, 2015. In fiscal 2013, the Company recorded stock-based compensation expense of $4.7 million for its ESPP. No shares have been purchased by employees under the ESPP as of and for the fiscal year ended December 28, 2013.
	Stock Option Activity
	Stock options granted to new hires, under the 2013 Equity Plan and formerly under the Option Plan (together, the “Option Plans”), are generally subject to a four-year vesting period whereby options become 25% vested on the first anniversary from the grant date and then ratably monthly thereafter through the end of the vesting period. Vested options may be exercised up to ten years from the vesting commencement date.
	In fiscal 2013 and fiscal 2012, the Company granted its employees zero shares and 66,663 shares subject to performance-based options, respectively. These options vest based upon the achievement of sales goals for each individual grantee. Based upon the achievement of each individual’s sales goals, 21,749 shares and 9,123 shares subject to such options had vested as of December 28, 2013 and December 31, 2012, respectively. The Company recognized approximately $134,400 and $90,000 in stock-based compensation expense during fiscal 2013 and fiscal 2012, respectively. As of December 28, 2013 and December 31, 2012, 39,998 shares and 50,666 shares subject to such performance-based options, respectively, were outstanding, with unrecognized expense of $0.1 million and $0.2 million, net of estimated forfeitures, respectively.
	In fiscal 2013, the Company granted 448,349 shares subject to fully-vested options to certain employees, with an average exercise price of $0.02 per share, as substitute options to purchase our common stock in connection with the LLC Conversion. In fiscal 2012, the Company granted 153,647 shares subject to fully-vested options to certain employees, with an average exercise price of $10.38 per unit. Stock-based compensation expense recognized in fiscal 2013 and fiscal 2012 in connection with these fully vest options was $8.5 million and $0.9 million, respectively.

Restricted Stock Unit Activity
RSUs generally vest ratably on a quarterly basis over a period of three to four years. The vesting is subject to the employee’s continuing service with the Company over that period. Until vested, RSUs do not have the voting or dividend participation rights of common stock and the shares of common stock underlying the awards are not considered issued and outstanding. RSUs are converted into shares of the Company’s common stock upon vesting on a one-for-one basis. Prior to our IPO, vesting of RSUs was subject to the occurrence of a liquidity event, and in certain instances additional vesting criteria. The liquidity event was defined as the earliest of (i) the closing of a sale event of the Company, or (ii) six months following the IPO of the Company’s common stock.
The following table summarizes the RSU activity under the Company’s Option Plans:

Aggregate intrinsic value represents the difference between the Company’s fair market value per share of $28.29 and $13.11 as of December 28, 2013 and December 31, 2012, respectively, and the exercise price of the awards for the total number of underlying RSUs. Weighted average fair value per share for RSUs vested in fiscal 2013 was $11.06 million. Total intrinsic value of RSUs vested in fiscal 2013 was $1.5 million. In fiscal 2013, the Company recognized stock-based compensation expense of $6.0 million related to its RSUs.
The Company did not recognize stock-based compensation expense related to its RSUs for fiscal 2012 as the liquidity event had not occurred as of December 31, 2012. Accordingly, none of the Company’s outstanding RSUs was vested or exercisable as of December 31, 2012.
Stock-Based Compensation Expense
The fair value of stock options is estimated on the date of grant using the Black-Scholes option-pricing model. It is based on the “simplified method” for developing the estimate of the expected life of a “plain vanilla” stock option. Under this approach, the expected term is presumed to be the midpoint between the average vesting date and the end of the contractual term of the option. The risk-free interest rate for the period covering the expected life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility was determined based on historical volatility of the common stock of publicly traded comparable companies and the expected life of the options since the Company has not had sufficient public trading history of its common stock. The dividend yield assumption is based on the Company’s historical dividend payouts. The Company uses the graded vesting method for expense attribution.
Prior to the IPO, determining the market value of the Company’s common stock required complex and subjective judgment and estimates. There was inherent uncertainty in making these judgments and estimates. The absence of an active market for the Company’s common units or common stock prior to the IPO required the Board to estimate the fair value of its common stock for purposes of setting the exercise price of the options and estimating the fair value of common stock at each meeting at which options were granted based on factors such as the valuations of comparable companies, the status of the Company’s development and sales efforts, revenue growth and additional objective and subjective factors relating to the Company’s business. The Company performed its analysis in accordance with applicable elements of the practice aid issued by the American Institute of Certified Public Accountants entitled Valuation of Privately Held Company Equity Securities Issued as Compensation.
The fair value of the option awards and ESPP purchase rights granted and the assumptions used in the Black-Scholes option pricing model are summarized as follows:
		Fiscal Year Ended

The cost of RSUs is determined using the fair value of the Company’s common stock on the date of the grant. In fiscal 2013, the Company granted 764,509 RSUs with a grant date fair value per share ranging from $15.57 to $38.33. In fiscal 2012, the Company granted 95,842 RSUs and 53,999 RSUs with a grant date fair value per share of $10.38 and $12.42, respectively, including performance-based RSUs covering 8,666 shares.
As of December 28, 2013, unrecognized compensation expense related to stock options, RSUs and ESPP purchase rights, net of estimated forfeitures, of $10.3 million, $10.9 million, and $5.1 million, respectively, with a weighted-average remaining amortization period of 1.4 years, 1.4 years and 0.9 year, respectively. As of December 31, 2012, excluding the 1,070,316 IPO Stock Options and 149,841 RSUs that were subject to the IPO, unrecognized compensation expense related to unvested stock options, net of estimated forfeitures, was $4.9 million with a weighted-average remaining amortization period of 1.8 years. There was no capitalized stock-based compensation expense for any of the periods presented.

	The Company recorded an income tax benefit of $20.7 million in fiscal 2013 primarily attributable to the impact of domestic deferred tax and a nominal amount of foreign income tax expense. In connection with the conversion from a Delaware LLC to a Delaware corporation under Subchapter C of Chapter 1 of the United States Internal Revenue Code, the Company is now subject to both federal and state income taxes and, therefore, the Company recognized deferred tax assets of $14.8 million, upon its conversion to a Delaware corporation, and an income tax benefit of $5.9 million for the tax impact on its results of operations as a Delaware corporation.

As of December 28, 2013, the Company had federal and state net operating loss carryforwards of approximately $13.1 million and $3.1 million, respectively, available to reduce any future taxable income. If not utilized, the federal and state net operating loss carryforwards will expire in fiscal 2033.
The Company also has federal and state research and development tax credit carryforwards of approximately $0.1 million and $0.2 million, respectively. If not utilized, the federal credit carryforwards will also expire in fiscal 2033. The state credit will carry forward indefinitely.
Utilization of the net operating loss carryforwards and credits may be subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the expiration of net operating losses and credits before utilization.
The Company uses the with-and-without approach described in guidance which has been incorporated into ASC 740, Income Taxes, to determine the recognition and measurement of excess tax benefits. Accordingly, the Company has elected to recognize excess income tax benefits from share-based awards in additional paid-in capital only if an incremental income tax benefit would be realized after considering all other tax attributes presently available to the Company. As of December 28, 2013, the amount of excess tax benefits from stock options included in federal and state net operating losses was $6.8 million and $1.8 million, respectively. The impact of this excess tax benefit will be recognized as additional paid-in capital when it reduces taxes payable. In addition, the Company has elected to account for the indirect effects of share-based awards on other tax attributes, such as the research, foreign and other tax credits, through the consolidated statement of operations.
The Company assesses the likelihood to recover its deferred tax assets. The Company considers all available evidence, both positive and negative, including historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for a valuation allowance. If it is not more-likely-than-not that the Company expects to recover its deferred tax assets, the Company will increase its provision for income taxes by recording a valuation allowance against the deferred tax assets that it estimates will not ultimately be recoverable. As of December 28, 2013, the Company determined that it was more-likely-than-not that the amount of deferred tax assets recorded on the balance sheet would be realized.
As of December 28, 2013, the Company had $0.2 million of unrecognized tax benefits, all of which would affect income tax benefit (expense) if recognized. As of December 28, 2013, the Company’s federal, state, and foreign returns for the tax years 2008 through the current period are still open to examination. The Company does not expect the unrecognized tax benefits to change significantly over the next 12 months. The Company recognizes both interest and penalties associated with uncertain tax positions as a component of income tax expense. As of December 28, 2013 and December 31, 2012, the Company had not accrued any interest or penalties associated with uncertain tax positions. The ultimate amount and timing of any future settlements cannot be predicted with reasonable certainty.
A reconciliation of the gross unrecognized tax benefit is as follows (in thousands):

As of December 28, 2013, the Company had not recorded any tax provision for U.S. federal and state income taxes on approximately $1.2 million of undistributed earnings in foreign subsidiaries, which it expects to reinvest outside of the U.S. indefinitely. If the Company were to repatriate these earnings to the U.S., it would be subject to U.S. income taxes, an adjustment for foreign tax credits, and foreign withholding taxes. The determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable.

Effective June 17, 2013, all shares of the then-outstanding redeemable convertible preferred stock were converted to common stock and are included in the weighted-average shares used to compute net (loss) income per share starting from the conversion date. Due to the net loss incurred in fiscal 2013, potential dilutive securities were excluded from the calculation of diluted net loss per share attributable to common stockholders for such period as their effect was anti-dilutive. Dilutive securities in the Company’s diluted net (loss) income per share calculation for the periods before the close of the Company’s IPO in June 2013 do not include stock options and RSUs with vesting contingent upon an IPO or a liquidity event.

	During the three months ended December 28, 2013, the Company identified immaterial errors related to income taxes and inventory in the unaudited interim financial statements for the quarterly periods ended June 29, 2013 and September 28, 2013. The benefit for income taxes was cumulatively overstated by $1.8 million through the nine month period ended September 28, 2013 as a result of the stock-based compensation expense from the Company’s ESPP being inappropriately included in the determination of the deferred income tax benefit. The recovery of previously written-down inventory was cumulatively understated by $0.1 million through the nine month period ended September 28, 2013 due to an error in the calculation. These errors did not impact any annual or other interim periods.
	The Company assessed the materiality of the above errors individually and in the aggregate on prior periods’ financial statements in accordance with the Securities and Exchange Commission’s Staff Accounting Bulletin No. 99 and, based on an analysis of quantitative and qualitative factors, determined that the errors were not material to the Company’s June 29, 2013 and September 28, 2013 interim consolidated financial statements and, therefore, these previously issued consolidated financial statements could continue to be relied upon and that amendments of the previously filed Quarterly Reports on Form 10-Q were not required. However, the cumulative errors would be material to the financial results for the three months ended December 28, 2013 if the aggregated corrections were recorded in such period. Accordingly, the Company will revise its previously issued interim financial statements for the three month periods ended June 29, 2013 and September 28, 2013 to correct the errors in future Quarterly Reports on Form 10-Q where interim financial statements for such periods are included. The Company has reflected the corrections of these errors in the applicable quarterly financial periods presented above.

	Use of Estimates
	The preparation of consolidated financial statements in conformity with GAAP requires management to make certain 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 periods. On an ongoing basis, the Company evaluates its estimates, including but not limited to those related to revenue recognition, provision for doubtful accounts, warranty reserve, excess and obsolete inventory write-downs, stock-based compensation expense, depreciable lives, and income taxes. The Company bases its estimates on historical experience, projections for future performance and other assumptions that it believes to be reasonable under the circumstances. Actual results could differ materially from those estimates.

The Company received proceeds of $93.4 million, net of underwriting discounts and commissions of $7.3 million and other offering expenses of approximately $4.0 million. In addition, certain selling stockholders sold 2,250,000 shares of common stock at a public offering price of $19.00 per share. The Company did not receive any proceeds from the sales of shares by the selling stockholders. In connection with its IPO, all of the Company’s then-outstanding redeemable convertible preferred stock was converted into 8.1 million shares of common stock.
Follow-On Public Offering	'
	Follow-On Public Offering
	On October 28, 2013, the Company completed its follow-on public offering, in which 5,100,000 shares of its common stock were sold at a public offering price of $38.50 per share. The Company sold 300,000 shares of common stock, for which the Company received proceeds of $10.2 million, net of underwriting discounts and commissions of $0.5 million and other offering expenses of approximately $0.8 million. In addition, the Company’s selling stockholders sold 4,800,000 shares of common stock, which included 293,718 shares of common stock issued upon the exercise of options by certain selling stockholders, with an aggregate exercise price of $1.3 million, at a public offering price of $38.50 per share. The Company did not receive any proceeds from the sale of shares by the selling stockholders.
Reverse Stock Split	'
	Reverse Stock Split
	Effective May 20, 2013, the Company completed a one-for-three reverse stock split, as approved by its Board of Directors (the “Board”). All shares and per share amounts set forth herein give effect to this reverse stock split.
Foreign Currency Transactions	'
	Foreign Currency Transactions
	The Company uses the U.S. dollar as its functional currency. Foreign currency assets and liabilities are remeasured into U.S. dollars using the end-of-period exchange rates except for nonmonetary assets and liabilities, which are remeasured using historical exchange rates. Expenses are remeasured using an average exchange rate for the respective period. Gains or losses from foreign currency transactions are included in other expense, net. Foreign currency transaction gains and losses have not been significant to the consolidated financial statements for all periods presented.
Cash Equivalents and Marketable Securities	'
	Cash Equivalents and Marketable Securities
	All highly liquid marketable securities with original or remaining maturities of less than three months at the date of purchase are considered to be cash equivalents. Marketable securities are generally classified as available-for-sale for use in current operations, if required, and are reported at fair value, with unrealized gains and losses, net of tax, presented as a separate component of stockholders’ equity under accumulated other comprehensive income. All realized gains and losses and unrealized losses resulting from declines in fair value that are other than temporary are recorded in other expense, net in the period of occurrence. The Company uses the specific identification method to determine the realized gains and losses on investments. For all investments in marketable securities, the Company assesses whether the impairment is other than temporary. If the fair value of a security is less than its amortized cost basis, an impairment is considered other than temporary if (i) the Company has the intent to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of its entire amortized cost basis, or (ii) the Company does not expect to recover the entire amortized cost of the security. If an impairment is considered other than temporary based on condition (i), the entire difference between the amortized cost and the fair value of the security is recognized in earnings. If an impairment is considered other than temporary based on condition (ii), the amount representing credit losses, defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis of the security, will be recognized in earnings, and the amount relating to all other factors will be recognized in other comprehensive income. The Company evaluates both qualitative and quantitative factors such as duration and severity of the unrealized losses, credit ratings, default and loss rates of the underlying collateral, structure and credit enhancements to determine if a credit loss may exist.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The Company records its financial assets and liabilities at fair value. The accounting guidance for fair value provides a framework for measuring fair value, clarifies the definition of fair value, and expands disclosures regarding fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the reporting date. The accounting guidance establishes a three-tiered hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:
	Level 1 – Quoted prices in active markets for identical assets or liabilities.
	Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	The Company recognizes transfers among Level 1, Level 2 and Level 3 classifications as of the actual date of the events or change in circumstances that caused the transfers.
	The Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and accrued liabilities have carrying amounts which approximate fair value due to the short-term maturity of these instruments.
Accounts Receivable	'
	Accounts Receivable
	Accounts receivable, which represent trade accounts receivable from both channel partners and direct customers, are recorded at the invoiced amounts and do not bear interest. The Company extends credit to its customers in the normal course of business and performs ongoing credit evaluations of its customers. The Company generally requires no collateral from its customers. The Company establishes an allowance for doubtful accounts for estimated losses resulting from the customer’s inability to make payments. Management determines the collectability of specific customer accounts by their past transaction history. If financial conditions of the Company’s customers were to deteriorate, adversely affecting their ability to make payments, additional allowances would be required. Estimates for allowance for doubtful accounts are charged to operating expenses and a credit to a valuation allowance. As of December 28, 2013 and December 31, 2012, the Company had not recorded an allowance for doubtful accounts.
Concentrations	'
	Concentrations
	The Company operates in highly competitive and rapidly changing markets that could negatively impact the Company’s operating results. A number of components that meet the Company’s manufacturing requirements are available only from single source suppliers. In addition, the Company relies on one contract manufacturer to manufacture substantially all of its products. The inability of its single source suppliers and contract manufacturer to provide the Company with adequate supplies of high-quality components and products could cause a delay in order fulfillment, which could adversely affect the Company’s revenue, cost of sales and operating results.
	Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash, cash equivalents, investments and accounts receivable. The Company places the majority of its cash, cash equivalents and investments with a limited number of major financial institutions in the United States that management believes are creditworthy. Such deposits may exceed the insured limits provided on them. The Company mitigates credit risk associated with its accounts receivable by performing ongoing credit evaluations of its customers and establishes an allowance for doubtful accounts for estimated losses based on management’s assessment of the collectability of customer accounts. No end-user customer accounted for 10% of more of total accounts receivable.
	The Company sells its products primarily through channel partners, including distributors and resellers, and occasionally directly to end-user customers. For fiscal 2013, 2012 and 2011, no end-user customer accounted for 10% or more of revenue.
	Customers that represented more than 10% of revenue and accounts receivable are the following:
		Fiscal Year Ended
		December 28,			December 31,			December 31,
		2013			2012			2011
	Percent of Revenue:
	Customer A (distributor)		51	%		63	%		37	%
	Customer B (reseller)		*			*			18	%
	* less than 10%
		As of
		December 28,			December 31,
		2013			2012
	Percent of Accounts Receivable:
	Customer A (distributor)		23	%		50	%
	Customer B (reseller)		11	%		*
	* less than 10%
Inventories	'
	Inventories
	Inventory is valued at the lower of cost computed on a first-in, first-out basis, or market value. The Company writes down inventory in excess of forecasted demand over a certain period. In these cases, inventory is reduced to estimated realizable value based on historical usage and expected demand. At the point of inventory write-down, 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. Inherent in the Company’s estimates of market value in determining inventory valuation are estimates related to economic trends, future demand for the Company’s products, and technical obsolescence of products. The Company uses a contract manufacturer to provide manufacturing services for its products. During the normal course of business, in order to manage manufacturing lead times and help ensure adequate component supply, the Company enters into agreements with the contract manufacturer that either allow them to procure inventory based upon criteria as defined by the Company, or establish the parameters defining the Company’s requirements. A portion of the Company’s reported purchase commitments arising from these agreements consists of non-cancelable commitments. The Company records a liability for firm, non-cancelable and unconditional purchase commitments for quantities in excess of its future demand forecasts consistent with the valuation of the Company’s excess and obsolete inventory.
	In fiscal 2013, the Company recognized a $0.8 million net inventory benefit within cost of revenue which included the sale of previously written-down inventory of $1.5 million. The Company recorded inventory write-downs of $1.5 million and $3.2 million in fiscal 2012 and fiscal 2011, respectively, as a component of cost of revenue.
Property and Equipment	'
	Property and Equipment
	Property and equipment are stated at cost and depreciated using the straight–line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the lesser of the useful life of these improvements or the remaining term of the lease. Maintenance and repairs are charged to operations as incurred.
	The useful lives of the property and equipment are as follows:
	Furniture and fixtures	5 years
	Software	3 to 5 years
	Equipment and machinery	1.5 to 3 years
	Leasehold improvements	Shorter of lease term or estimated useful life
Research and Development and Software Development Costs	'
	Research and Development and Software Development Costs
	Research and development costs are expensed as incurred, except for certain software development costs. To-date, software development costs qualifying for capitalization have been insignificant. Accordingly, the Company has not capitalized any software development costs.
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the anticipated future net undiscounted cash flows to the related assets’ carrying values.
	If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the projected discounted future net cash flows arising from the asset. No assets were determined to be impaired during any of the periods presented.
Revenue Recognition	'
	Revenue Recognition
	The Company generates product revenue from sales of traffic visibility solutions to channel partners and direct customers as well as services revenue from sales of maintenance and support contracts and other billable services. Most of the Company’s products are hardware appliances containing software components that function together to deliver the essential functionality of the solution. The Company typically delivers products and services in a single transaction. The deliverables consist of traffic visibility solutions, maintenance and support, and other billable services. The Company’s typical arrangement includes the sale of one or multiple products that include first year maintenance and support as well as standard warranty. Other arrangements consist of the sale of products bundled with additional maintenance and support or a renewal of maintenance and support contracts. Billable services are billed in advance or when service is provided and performed as requested by customers. Under maintenance and support contracts, services are provided as needed by customers over the fixed arrangement term. The Company does not grant its customers a general right of return or any refund terms, except to two of the Company’s distributors that have a general right of return and in that case, revenue is deferred until sell-through has occurred. Revenue is reported net of rebates, discounts and any other sales incentives.
	The Company recognizes revenue when (1) persuasive evidence of an arrangement exists, (2) delivery has occurred or services have been rendered, (3) sales price is fixed or determinable and (4) collectability is reasonably assured.
	When sales arrangements contain multiple elements and software and non-software components that function together to deliver the products’ essential functionality, the Company allocates revenue to each element based on a selling price hierarchy: vendor-specific objective evidence (“VSOE”) if available, third-party evidence (“TPE”) of the selling price if VSOE is not available, or best estimated selling prices (“ESP”) if neither VSOE nor TPE is available.
	When the Company enters in arrangements to provide more than one product or service (“multiple deliverables”), these arrangements are evaluated to determine if the multiple elements consist of more than one unit of accounting and can be separated accordingly. Based on separation criteria under the guidance, deliverables in multiple element arrangements can be segregated into separate units of accounting if they have value to the customer on a standalone basis. If deliverables can be separated into individual units of accounting, then the arrangement consideration is allocated among deliverables based on their relative selling price. Revenue from each deliverable is recognized when all requirements are met for that specific deliverable. If deliverables cannot be separated into separate units of accounting, then the arrangement will be accounted for as a single unit of accounting and revenue will be recognized when all requirements are met for all deliverables within the arrangement. The Company has established VSOE for maintenance and support contracts since the majority of selling prices fall within a narrow range when sold separately. TPE is not used since this information is not widely available in the market and we do not consider our products to be similar to or interchangeable with our competitors’ products in standalone sales to similarly situated customers. For deliverables with no established VSOE, the Company determines the standalone selling price for such deliverables by establishing ESP, which incorporates historical selling prices, the effect of market conditions, gross margin objectives and pricing practices, as well as entity specific factors. The Company monitors and evaluates ESP on a regular basis to ensure that changes in circumstances are accounted for in a timely manner.
	Services revenue is recognized ratably over the contractual support period, which is typically one year and can be up to five years.
	In accordance with contractual provisions, the Company may offer cooperative marketing funds based on a fixed dollar percentage of product sales to certain of its channel partners or to fund specific marketing activities for these partners. The Company records such amounts as a reduction to revenue or, if the Company has evidence of fair value of the separable and identifiable benefit received, as marketing expense.
	Revenue is recorded net of sales taxes. Costs of products not yet recognized as revenue are deferred and included as a component of prepaid expenses and other current assets in the consolidated balance sheets. As of December 28, 2013 and December 31, 2012, deferred product costs were $0.9 million and $0.6 million, respectively.
Shipping and Handling Charges	'
	Shipping and Handling Charges
	Shipping and handling costs are recorded in cost of revenue in the period products are shipped to customers.
Warranty	'
	Warranty
	Beginning on February 1, 2011, the Company began providing five-year warranties on its products against defects in manufacturing. Prior to February 1, 2011, the Company provided a one-year warranty on its products. The Company accrues for potential liability claims as a component of cost of product revenue based on historical trends of product failure rates and the expected material and labor costs to provide warranty services. The accrued warranty balance is reviewed periodically for adequacy and is included in accrued liabilities and other liabilities, non-current on the consolidated balance sheets.
Stock-Based Compensation	'
	Stock-Based Compensation
	Stock-based compensation expense related to stock-based transactions, including employee and director awards, as well as employee stock purchase plan purchase rights (“ESPP purchase rights”), is measured and recognized in the consolidated financial statements based on fair value of the award on the grant date. The fair value of option awards and ESPP purchase rights is estimated using the Black-Scholes option-pricing model. This model requires assumptions including the market value of the Company’s common stock, expected volatility, expected term of the award, expected dividend yield and risk-free interest rate. Expected term for stock option awards is determined based on the mid-point of the vest period and the contractual period of each option award due to the Company’s limited historical stock option exercise data. Expected volatility is established based on the historical volatility of the common stock of a peer group of publicly traded companies. The stock-based compensation expense, net of estimated forfeitures, is recognized on a graded-vesting basis over the requisite service periods of the awards, unless a performance-based condition exists. Expense for performance-based awards are recognized when the issuance of the underlying awards are probable. Expense for consultant awards are measured based on the fair value on the vest date. Expenses related to the option grants to consultants that have not been vested as of the reporting date are marked to market until the earlier of the commitment or the completion of the underlying performance. The Company estimates a forfeiture rate to calculate the stock-based compensation for its stock-based awards based on an analysis of its historical experience, analysis of employee turnover and other related factors.
Advertising Costs	'
	Advertising Costs
	Expenses related to advertising of products are charged to sales and marketing expense as incurred. For all periods presented, advertising expenses were insignificant.
Deferred Offering Costs	'
	Deferred Offering Costs
	Deferred offering costs, consisting of legal, accounting and filing fees related to the IPO or the follow-on public offering, were capitalized as other assets and offset against the proceeds received upon the completion of each offering. As of December 28, 2013 and December 31, 2012, the Company had capitalized zero and $2.2 million, respectively, of deferred offering costs within other assets on its consolidated balance sheets.
Income Taxes	'
	Income Taxes
	The Company is subject to U.S. federal income taxes as well as state taxes. In addition, the Company is subject to taxes in the foreign jurisdictions where it operates.
	Prior to the LLC Conversion in May 2013, the Company was a Delaware limited liability company that passed through income and losses to its members. As a result, the Company was not subject to any U.S. federal or state income taxes as the related tax consequences were reported by the individual members.
	Effective upon the completion of the LLC Conversion, the Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in its financial statements or tax returns. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carry forwards. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized. Accordingly, the Company assessed the need for a valuation allowance based on the ASC 740 more-likely-than-not realization threshold criterion. Consideration was given to all positive and negative evidence related to the realization of the deferred tax assets. This assessment considered, among other matters, the nature, frequency and severity of current and cumulative losses, forecasts of future profitability, the duration of statutory carryforward periods, experience with operating loss and tax credit carryforwards expiring, and tax planning alternatives. Significant judgment was required to determine whether a valuation allowance was necessary and the amount of such valuation allowance, if appropriate.
	The Company applies the authoritative accounting guidance prescribing a threshold and measurement attribute for the financial recognition and measurement of a tax position taken or expected to be taken in a tax return. The Company recognizes liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more-likely-than-not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the tax liability as the largest amount that is more-likely-than-not to be realized upon ultimate settlement. The Company also accounts for any related interest and penalty charges as a component of income taxes.
Comprehensive (Loss) Income	'
	Comprehensive (Loss) Income
	Comprehensive (loss) income is defined as a change in equity of a business enterprise during a period, resulting from transactions from non-owner sources. Comprehensive (loss) income comprises all components of net (loss) income and all components of other comprehensive income within stockholders’ equity. The Company’s other comprehensive income includes unrealized gains and losses from its available-for-sale securities that are not considered other-than-temporarily impaired.
Earnings Per Share	'
	Earnings Per Share
	Basic net (loss) income per share attributable to common stockholders is calculated by dividing the net (loss) income attributable to common stock holders by the weighted-average number of common stock outstanding for the period.
	Diluted net income per share attributable to common stockholders is computed by giving effect to all potential dilutive common stock outstanding during the period, including options, restricted stock units (“RSUs”) and ESPP purchase rights. The computation of diluted net income does not assume conversion or exercise of potentially dilutive securities that would have an anti-dilutive effect on earnings. The dilutive effect of outstanding options is computed using the treasury stock method. In periods when the Company has incurred a net loss, potential dilutive common securities outstanding have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is antidilutive.
	Prior to the conversion of its redeemable convertible Series A preferred stock (the “Series A preferred stock”) to common stock, effective June 17, 2013, the Company applied the two-class method for calculating and presenting earnings per share as the Series A preferred stock was considered a participating security due to the rights of cumulative preferred return. Participating securities are defined as securities that participate in dividends with common units according to a pre-determined formula or a contractual obligation to share in the income of the entity. Under the two-class method, net (loss) income is allocated between common stock and other participating securities based on their participating rights. Accordingly, earnings allocated or distributed to the Series A preferred stock as well as the related number of outstanding shares of the Series A preferred stock have been excluded from the computation of basic and diluted net (loss) income per share attributable to common stockholders.
	Dilutive securities that were subject to the Company’s IPO were excluded from the Company’s diluted net (loss) income per share calculation for the periods before the close of the Company’s IPO in June 2013.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In March 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update requiring an entity to release into net income the entire amount of a cumulative translation adjustment related to its investment in a foreign entity when as a parent it either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets within a foreign entity. This accounting standard update will be effective prospectively for the Company beginning in the first quarter of fiscal 2014. The Company does not expect the adoption of this accounting standard update to have a material impact on its consolidated financial statements.
	In July 2013, the FASB issued a new accounting standard update that requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the consolidated balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. Early adoption or a retrospective application is permitted. The Company is required to adopt this new standard on a prospective basis in the first quarter of fiscal 2014. The Company does not expect the adoption of this accounting standard update to have a material impact on its consolidated financial statements.
