SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Accounting Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, the Company evaluates these estimates, including those related to allowance for doubtful accounts, inventory valuation, warranty costs, stock-based compensation and income taxes, among others. The Company bases estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ materially from these estimates. Segments Management has determined that it operates as one reportable and operating segment as it only reports financial information on an aggregate and consolidated basis to its chief executive officer, who is the Company’s chief operating decision maker. See Note 13. Recognition of Revenues Revenues consist primarily of revenues from the sale of hardware and management tools, as well as the related implied post contract customer support (“PCS”). The Company recognizes revenues when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and the collectability of the resulting receivable is reasonably assured. In cases where the Company lacks evidence that collectability of the resulting receivable is reasonably assured, it defers recognition of revenue until the receipt of cash. For the Company’s sales, evidence of the arrangement consists of an order from a customer. The Company considers delivery to have occurred once its products have been shipped and title and risk of loss have been transferred. For the Company’s sales, these criteria are met at the time the products are transferred to the customer. The Company’s arrangements with customers do not, in most cases, include provisions for cancellation, returns, inventory swaps or refunds that would significantly impact recognized revenues. The Company records amounts billed to distributors for shipping and handling costs as revenues. The Company classifies shipping and handling costs incurred by it as cost of revenues. Deposit payments received from distributors in advance of recognition of revenues are included in current liabilities on the Company’s balance sheet and are recognized as revenues when all the criteria for recognition of revenues are met. The Company’s multi-element arrangements generally include two deliverables. The first deliverable is the hardware and software essential to the functionality of the hardware device delivered at the time of sale. The second deliverable is the implied right to PCS included with the purchase of certain products. PCS is this right to receive, on a when and if available basis, future unspecified software upgrades and features relating to the product’s essential software as well as bug fixes, email and telephone support. The Company uses a hierarchy to determine the allocation of revenues to the deliverables. The hierarchy is as follows: (i) vendor-specific objective evidence of fair value (“VSOE”), (ii) third-party evidence of selling price (“TPE”), and (iii) best estimate of the selling price (“BESP”).
(i) | VSOE generally exists only when a company sells the deliverable separately and is the price actually charged by the company for that deliverable. Generally the Company does not sell the deliverables separately and, as such, does not have VSOE.
(ii) | TPE can be substantiated by determining the price that other parties sell similar or substantially similar offerings. The Company does not believe that there is accessible TPE evidence for similar deliverables.
(iii) | BESP reflects the Company’s best estimates of what the selling prices of elements would be if they were sold regularly on a stand-alone basis. The Company believes that BESP is the most appropriate methodology for determining the allocation of revenue among the multiple elements.
The Company allocates revenues between these two deliverables using the relative selling price method which is based on the estimated selling price for all deliverables. Revenues allocated to the delivered hardware and the related essential software are recognized at the time of sale provided the other conditions for recognition of revenues have been met. Revenues allocated to the PCS are deferred and recognized on a straight-line basis over the estimated life of each of these devices, which currently is two years. All cost of revenues, including estimated warranty costs, are recognized at the time of sale. Costs for research and development and sales and marketing are expensed as incurred. If the estimated life of the hardware product should change, the future rate of amortization of the revenues allocated to PCS would also change. The Company’s process for determining BESP for deliverables involves multiple factors that may vary depending upon the unique facts and circumstances related to each deliverable. For PCS, the Company believes its network operators and service providers would be reluctant to pay for such services separately. This view is primarily based on the fact that unspecified upgrade rights do not obligate the Company to provide upgrades at a particular time or at all, and do not specify to network operators and service providers which upgrades or features will be delivered. The Company believes that the relatively low prices of its products and its network operators’ and service providers’ price sensitivity would add to their reluctance to pay for PCS. Therefore, the Company has concluded that if it were to sell PCS on a standalone basis, the selling price would be relatively low. Key factors considered by the Company in developing the BESP for PCS include reviewing the activities of specific employees engaged in support and software development to determine the amount of time that is allocated to the development of the undelivered elements, determining the cost of this development effort, and then adding an appropriate level of gross profit to these costs. Cash and Cash Equivalents The Company considers investments purchased with a maturity period of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents are stated at cost which approximates fair value. The Company deposits cash and cash equivalents with financial institutions that management believes are of high credit quality. The Company’s cash and cash equivalents consist primarily of cash deposited in U.S. dollar denominated interest-bearing deposit accounts. Concentration of Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. The Company limits its exposure by primarily placing its cash in interest-bearing deposit accounts with high credit quality financial institutions. The Company derives its accounts receivable from revenues earned from customers located worldwide. The Company bases credit decisions primarily upon a customer’s past credit history. The Company’s standard credit terms are net 30 to 60 days. The Company subcontracts with other companies to manufacture most of its products. The Company relies on the ability of these contract manufacturers to produce the products sold to its distributors and original equipment manufacturers (“OEMs”). A significant portion of the Company’s products are manufactured by a few contract manufacturers. Inventory and Inventory Valuation The Company's inventories are primarily finished goods and, to a lesser extent, raw materials, which have been consigned to the Company's contract manufacturers. Inventories are stated at the lower of actual cost (computed on a first-in, first-out basis), or market value. Market value is based upon an estimated average selling price reduced by the estimated costs of disposal. The determination of market value involves numerous judgments including estimating average selling prices based up recent sales, industry trends, existing customer orders, and seasonal factors. Should actual market conditions differ from the Company's estimates, future results of operations could be materially affected. The Company reduces the value of its inventory for estimated obsolescence or lack of marketability by the difference between the cost of the affected inventory and the estimated market value. Write-downs are not reversed until the related inventory has been subsequently sold or scrapped. The valuation of inventory also requires the Company to estimate excess and obsolete inventory. The determination of excess or obsolete inventory is estimated based on a comparison of the quantity and cost of inventory on hand to the Company's forecast of customer demand. Customer demand is dependent on many factors and requires the Company to use significant judgment in our forecasting process. The Company also makes assumptions regarding the rate at which new products will be accepted in the marketplace and at which customers will transition from older products to newer products. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required, which would have a negative impact on the Company's gross margin. If the Company ultimately sells inventory that has been previously written down, the Company's gross margins in future periods will be positively impacted. Deferred Cost of Revenues Deferred cost of revenues consist of the cost of product shipped to distributors for which the rights and obligations of ownership have passed to the distributor but revenues have not yet been recognized primarily because the collectability criterion for revenue recognition has not been fulfilled. The Company classifies these amounts as deferred cost of revenues. All deferred costs of revenues are stated at cost. The Company periodically assesses the recoverability of deferred cost of revenues and writes down the deferred cost of revenues balances to establish a new cost basis when recovery of deferred cost of revenues is not reasonably assured. The Company evaluates recoverability based on various factors including the length of time the product has been held at the distributor’s site and the financial viability of the distributor. Product Warranties The Company offers warranties on certain products, generally for a period of one year, and records a liability for the estimated future costs associated with potential warranty claims. The warranty costs are reflected in the Company’s consolidated statement of operations and comprehensive income within cost of revenues. The warranties are typically in effect for 12 months from the distributor’s purchase date of the product. The Company’s estimate of future warranty costs is largely based on historical experience factors including product failure rates, material usage, and service delivery cost incurred in correcting product failures. In certain circumstances, the Company may have recourse from its contract manufacturers for replacement cost of defective products, which it also factors into its warranty liability assessment. Allowance for Doubtful Accounts The Company records an allowance for doubtful accounts for estimated probable losses on uncollectible accounts receivable. In estimating the allowance, management considers, among other factors, (i) the aging of the accounts receivable, (ii) the Company’s historical write offs, (iii) the credit worthiness of each distributor based on payment history and (iv) general economic conditions. In cases where the Company is aware of circumstances that may impair a specific distributor’s ability to meet its obligations to the Company, the Company records a specific allowance against amounts due from the distributor, and thereby reduces the net recognized receivable to the amounts it reasonably believes will be collected. The allowance for doubtful accounts activity was as follows (in thousands):

Fair Value of Financial Instruments The carrying value of the Company’s cash equivalents, accounts receivable, accounts payable and other current liabilities approximate fair value due to their short maturities. The fair value of the Company's cash equivalents and debt are disclosed in Note 3. Long Lived Assets The Company evaluates its long lived assets including property and equipment for impairment whenever events or changes in circumstances indicate that the carrying value of these assets may not be recoverable. An impairment loss is recognized when the net book value of such assets exceeds the estimated future undiscounted cash flows attributable to the assets or asset group. If impairment is indicated, the asset is written down to its estimated fair value. The Company did not recognize any impairment losses for fiscal 2014, 2013 and 2012. Property and Equipment Furniture, fixtures and equipment are recorded at cost. The Company computes depreciation or amortization using the straight line method over estimated useful lives, as follows:
|  | Estimated Useful Life
Testing equipment |  | 3 to 5 years
Computer and other equipment |  | 3 to 5 years
Furniture and fixtures |  | 3 years
Leasehold improvements |  | shorter of lease term or useful life
Upon retirement or disposition, the asset cost and related accumulated depreciation are removed with any gain or loss recognized in the statement of operations. Expenditures for maintenance and repairs are charged to operations as incurred. Intangible Assets The Company’s intangible assets consist primarily of legal costs associated with application for and registration of the Company’s trademarks. The Company amortizes all acquisition-related intangible assets that are subject to amortization over the estimated useful life based on economic benefit, which is generally 5 years. Leases The Company leases its facilities under cancelable and noncancelable operating leases. For leases that contain rent escalation or rent concessions provisions, the Company records the total rent expense during the lease term on a straight line basis over the term of the lease. The Company records the difference between the rent paid and the straight line rent as a deferred rent liability in the accompanying consolidated balance sheets. Advertising Costs The Company expenses all advertising costs as incurred. Income Taxes The Company accounts for income taxes in accordance with accounting guidance which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in its financial statements or tax returns. Deferred tax assets and liabilities are determined based on the temporary difference between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The Company establishes valuation allowances when necessary to reduce deferred tax assets to the amount it expects to realize. The assessment of whether or not a valuation allowance is required often requires significant judgment including current operating results, the forecast of future taxable income and ongoing prudent and feasible tax planning initiatives. In addition, the Company’s calculation of its tax liabilities involves dealing with uncertainties in the application of complex tax regulations. The Company may be subject to income tax audits in all of the jurisdictions in which it operates and, as a result, must also assess exposures to any potential issues arising from current or future audits of current and prior years’ tax returns. Accordingly, the Company must assess such potential exposures and, where necessary, provide a reserve to cover any expected loss. To the extent that the Company establishes a reserve, its provision for income taxes would be increased. If the Company ultimately determines that payment of these amounts is unnecessary, it reverses the liability and recognizes a tax benefit during the period in which it determines that the liability is no longer necessary. The Company records an additional charge in its provision for taxes in the period in which it determines that tax liability is greater than its original estimate. Stock-based Compensation The Company records stock-based awards at fair value as of the grant date and recognize expense, net of forfeitures, ratably on a straight-line basis over the requisite service period, which is generally the vesting term of the awards. The Company estimates the fair value of stock option awards on the grant date using the Black-Scholes option pricing model. The determination of the fair value of a stock-based award on the date of grant using the Black-Scholes option-pricing model is affected by the Company's stock price on the date of grant as well as assumptions regarding a number of complex and subjective variables. These variables include the Company's expected stock price volatility over the expected term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate for the expected term of the award and expected dividends. Restricted stock units are valued based on the fair value of the Company's common stock on the date of grant. Since the Company's initial public offering on October 14, 2011, the fair value of our common stock is determined using the closing market price of the Company's common stock as of the date of grant. Commitments and Contingencies The Company periodically evaluates all pending or threatened contingencies and any commitments, if any, that are reasonably likely to have a material adverse effect on its results of operations, financial position or cash flows. The Company assesses the probability of an adverse outcome and determines if it is remote, reasonably possible or probable. If information available prior to the issuance of the Company’s financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the Company’s financial statements, and the amount of the loss, or the range of probable loss can be reasonably estimated, then such loss is accrued and charged to operating expenses. If no accrual is made for a loss contingency because one or both of the conditions pursuant to the accounting guidance are not met, but the probability of an adverse outcome is at least reasonably possible, the Company discloses the nature of the contingency and provides an estimate of the possible loss or range of loss, or states that such an estimate cannot be made. Foreign Currency Translation The functional currency of the Company and its subsidiaries is the U.S. dollar. For foreign operations, local currency denominated assets and liabilities are remeasured at the period end exchange rates, and revenues, costs and expenses are remeasured at the average exchange rates during the fiscal year. Foreign exchange gains and losses have been immaterial to the Company’s results of operations to date. Deferred Offering Costs Deferred offering costs, consisting of legal, accounting and other fees and costs relating to the Company’s initial public offering were capitalized. Deferred offering costs of $3.1 million were offset against initial public offering proceeds upon the closing of the offering in October 2011. Research and Development Costs and Capitalized Software Development Costs Research and development expenses are expensed as incurred. Research and development expenses associated with software development are expensed as incurred as our software is typically released to end customers immediately after technological feasibility has been established. Earnings Per Share The Company applies the two-class method for calculating and presenting earnings per share (“EPS”). Under the two-class method, net income is allocated between shares of common stock and other participating securities based on their participating rights. Participating securities are defined as securities that participate in dividends with common stock according to a pre-determined formula or a contractual obligation to share in the income of the entity. Basic EPS is computed by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted EPS is computed by dividing the amount of net income available to common stockholders outstanding plus income allocable to participating securities, to the extent they are dilutive, by the weighted average number of shares of common stock and potential dilutive shares outstanding during the period if the effect is dilutive. The Company’s potentially dilutive common securities include outstanding stock options, restricted stock units and preferred stock. Recent Accounting Pronouncements In June 2014, the Financial Accounting Standards Board, or FASB, issued a new accounting standard update on revenue from contracts with customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: Step 1: Identify the contract(s) with a customer. Step 2: Identify the performance obligations in the contract. Step 3: Determine the transaction price. Step 4: Allocate the transaction price to the performance obligations in the contract. Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative information is required about contracts with customers, significant judgments and any assets recognized from the costs to obtain or fulfill a contract. The guidance will be effective for the Company beginning July 1, 2017. The Company is currently assessing the impact of this new guidance. In July 2013, the FASB issued a new accounting standard update on the financial statement presentation of unrecognized tax benefits. The new guidance provides that a liability related to an unrecognized tax benefit would be presented as a reduction of a deferred tax asset for a new operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. The new guidance will become effective for the Company on July 1, 2014 and it should be applied prospectively to unrecognized tax benefits that exist as of the effective date with retrospective application permitted. The Company has assessed the impact of this new guidance, however the Company does not expect adoption to have a significant impact on its consolidated financial statements.
