Description of Business and Summary of Significant Accounting Policies
Note 1.  Description of Business and Summary of Significant Accounting Policies
 
Nature of Business:    Network Equipment Technologies, Inc. (the Company or NET) provides network and VoIP solutions to enterprises and government agencies that seek to reduce the cost to deploy next generation unified and secure communications applications. For over a quarter of a century, NET has delivered solutions for multi-service networks requiring high degrees of versatility, security and performance. Today, the Company's broad family of products enables interoperability and integration with existing networks for migration to secure IP-based communications. Broadening NET's voice solutions, Quintum Technologies (Quintum), now a part of NET, is a VoIP innovator whose applications bring the reliability and clarity of public telephone networks to Internet telephony and unified communications. NET was founded in 1983.
 
Liquidity:  With the exception of fiscal 2008, the Company has incurred net losses since fiscal 1998. The Company believes that existing cash, cash equivalents and short-term investments will be sufficient to fund operations for at least the next twelve months. However, if the effects of the restructuring that the Company commenced in January 2012 and continued in March 2012 are not materially consistent with management's expectations, the Company may encounter cash flow and liquidity issues during that period, which may require the Company to evaluate alternatives and take appropriate steps to address such issues, either by further reducing cash consumption, raising additional capital, or a combination of measures. If such steps are needed the Company cannot be assured that it will be able either to sufficiently reduce cash consumption without adverse effects on its business or to obtain additional capital on acceptable terms, if at all.
 
Principles of Consolidation:    The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated.
 
Segments:    The Company's management uses consolidated financial information in determining how to allocate resources and assess performance. For this reason, the Company has determined that it is engaged in a single reportable segment.
 
Basis of Presentation:    The Company's fiscal year ends on the last Friday in March. In most years, including fiscal 2011 and 2010, the fiscal year is 52 weeks, with each quarter comprised of thirteen weeks, which allows comparability of quarter over quarter results. Fiscal year 2012 included 53 weeks, with the extra week occurring in the three month period ended September 30, 2011.
 
Revenue Recognition:  The Company derives revenue primarily from the sales of hardware, software, services, post-contract support (PCS), and professional services. PCS typically includes unspecified software updates and upgrades on an if-and-when available basis and telephone and internet access to technical support personnel.
 
In October 2009, the Financial Accounting Standards Board (FASB) amended the accounting standards for revenue recognition to remove tangible products containing software components and non-software components that function together to deliver the product's essential functionality from the scope of industry specific software revenue recognition guidance. In October 2009, the FASB also amended the standards for multiple deliverable revenue arrangements to:
 
 
(i)
provide updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be separated, and how the arrangement consideration should be allocated among its elements;
 
 
(ii)
require an entity to allocate the revenue using estimated selling prices (ESP) of the deliverables if there is no vendor specific objective evidence (VSOE) or third party evidence of selling price (TPE); and
 
 
(iii)
eliminate the use of the residual method and require an entity to allocate revenue using the relative selling price method.
 
This new accounting guidance became applicable to the Company beginning the first quarter of its fiscal 2012. The Company adopted this guidance for transactions that were entered into or materially modified on or after March 26, 2011 using the prospective basis of adoption.
 
Product revenue is recognized when the Company has a contract with its customer, the product has been shipped as required by the contract and risk of loss has passed to its customer, the price is fixed or determinable, and the collectability of the related receivable is probable. If the customer has a right of acceptance and the Company has not yet obtained acceptance, revenue is deferred until the terms of acceptance are satisfied. When product revenue is deferred, the Company also defers the associated cost of goods until the revenue is recognized. The Company recognizes service revenue upon completion of the service or, for ongoing services such as PCS, ratably over the period of the contract.
 
Revenue on sales through resellers is recognized upon transfer of title to the reseller. Many of the sales to the Company's resellers are based upon firm commitments from their end customer; as a result, these resellers carry little or no inventory of NET products. For the Company's Promina, VX, NX and UX products, NET's customers generally do not have the right to return the equipment. For the Company's Tenor product line, NET customers are subject to agreements allowing for limited rights of return and price protection. Accordingly, revenues are reduced for the Company's estimates of liability related to these rights. The estimate for returns is recorded at the time the related sale is recognized and is adjusted periodically based on historical rates of returns and other related factors. The reserves for price protection are recorded at the time these programs are offered. Price protection is estimated based on specific programs, expected usage and historical experience.
 
The new revenue recognition guidance does not generally change the units of accounting for the Company's revenue transactions. All of the products and services continue to qualify as separate units of accounting. The Company analyzes all of its products, software and services and considers the features and functionalities of the individual elements and the stand-alone sales of those individual components among other factors, to determine which elements are essential or non-essential to the overall functionality of the networking equipment. The Company's core software (herein after referred to as 'essential software') is integrated with hardware and is essential to the functionality of the networking equipment. The Company's sale of additional software provides increased features and functions, but is not essential to the overall functionality of the networking equipment (herein after referred to as 'non-essential software').
 
For transactions entered into prior to the first quarter of fiscal 2012, the Company recognized revenue based on the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 985-605 (formerly referred to as Statement of Position No. 97-2, Software Revenue Recognition). In accordance with ASC 985-605, the Company utilized the residual method to determine the amount of product revenue to be recognized. Under the residual method, the fair value of the undelivered elements, such as PCS, is deferred and the remaining portion of the arrangement consideration is recognized as product revenue. VSOE of fair value is limited to the price charged when the same element is sold separately. VSOE of fair value is established for PCS and professional services based on the volume and pricing of the stand-alone sales within a narrow range. The fair value of the post-contractual support is recognized on a straight-line basis over the term of the related support period, which is typically one month to three years.
 
For transactions entered into or materially modified on or after the beginning of the first quarter of fiscal 2012, the total arrangement fees were allocated to all the deliverables based on their respective relative selling prices. The relative selling price is determined using VSOE when available. When VSOE cannot be established, the Company attempts to determine the TPE for the deliverables. TPE is determined based on competitor prices for similar deliverables when sold separately by the competitors. Generally the Company's product offerings differ from those of its competitors and comparable pricing of its competitors is often not available. Therefore, the Company is typically not able to determine TPE. When the Company is unable to establish selling price using VSOE or TPE, the Company uses ESP in its allocation of arrangement fees. The ESP for a deliverable is determined as the price at which the Company would transact if the products or services were sold on a stand-alone basis.
 
The Company has been able to establish VSOE for its PCS and professional services based on the volume and the pricing of the stand-alone sales for these services within a narrow range.
 
The Company has determined the ESP of its products and services for which VSOE has not been established based on an analysis of (i) the list price, which represents a component of the Company's current go-to market strategy, as established by senior management taking into consideration factors such as geography and the competitive and economic environment and (ii) an analysis of the historical pricing with respect to both the Company's bundled and stand-alone sales of each product or service.
 
The Company's multiple element arrangements may include non-essential software deliverables that are subject to the industry specific software revenue recognition guidance. The revenue for these multiple element arrangements is allocated to the non-essential software deliverables and the non-software deliverables based on the relative selling prices of all of the deliverables in the arrangement using the hierarchy in the new revenue accounting guidance. As the Company has not been able to obtain VSOE for all of the non-essential software deliverables in the arrangement, revenue allocated to such non-essential software elements is recognized using the residual method in accordance with industry specific software revenue recognition guidance as the Company was able to obtain VSOE for the undelivered elements bundled with such non-essential software elements. Under the residual method, the amount of revenue recognized for the delivered non-essential software elements equaled the total allocated consideration less the VSOE of any undelivered elements bundled with such non-essential software elements.
 
The change from the residual to the relative selling price method did not have a material impact on the allocation of revenue to the arrangement deliverables, nor did the Company change its assessment of the deliverables contained within its revenue arrangements. The adoption of the new revenue accounting guidance was not material to the Company's financial results for the fiscal year ended March 30, 2012.
 
Financial Statement Estimates:    The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Such management estimates and assumptions include, but are not limited to: assumptions related to contracts that have multiple elements, the allowances for sales returns and potentially uncollectible accounts receivable, the valuation of intangibles, inventories, warranty costs, the valuation allowance on deferred tax assets, certain reserves and accruals, estimated lives of depreciable and amortizable assets, and assumptions related to stock-based compensation. Actual results could differ from those estimates.
 
Cash and Cash Equivalents:    Cash and cash equivalents include highly liquid investments with original maturities of three months or less at the time of acquisition. The Company, at times, maintains cash balances in excess of the federally insured limit of $250,000.
 
Short-term Investments:    Short-term investments are primarily composed of highly liquid investments with original maturities of greater than three months at the time of acquisition. The Company classifies its short-term cash investments as available-for-sale securities. The carrying value of such securities is carried at fair market value with unrealized gains and losses being excluded from earnings and reported as a separate component of stockholders' equity. Realized gains and losses on the sale or maturity of short-term investments are determined on the basis of specific identification.
 
Restricted Cash:    Restricted cash consists of cash collateral related to short-term letters of credit required to be maintained for leases in the United States.
 
Allowance for Sales Returns:    A reserve for sales returns is established for primarily reseller and distributor customers, based on actual historical product returns.
 
Credit Risk and Allowance for Doubtful Accounts:    The Company's credit evaluation process and the reasonably short collection terms help mitigate credit risk. The Company typically does not require collateral or other security to support accounts receivable. The Company performs ongoing credit evaluations of its customers' financial condition and limits the amount of credit extended when deemed necessary. The Company maintains reserves for known recourse obligations and estimated bad debts. The allowance for doubtful accounts receivable is based on the assessment of the collectability of specific customer accounts and the aging of accounts receivable. Credit losses have historically been within the Company's expectations and the established allowances for doubtful accounts receivable.
 
Inventories:    Inventories are stated at the lower of cost (first-in, first-out) or market and include material, labor and manufacturing overhead costs.
 
Property and Equipment:    Property and equipment are stated at cost. Depreciation is computed using the straight-line method over estimated useful lives of generally three to ten years. Leasehold improvements are amortized over the shorter of the respective lease terms or estimated useful lives. Depreciation and amortization of property plant and equipment was $1.9 million, $2.3 million and $3.0 million in fiscal 2012, 2011 and 2010, respectively.
 
Long-lived asset: The Company reviews long-lived assets, including intangible assets with finite lives, property and equipment, and other assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Conditions that would necessitate an impairment assessment include a significant decline in the market price of an asset or asset group, a significant adverse change in the extent or manner in which an asset or asset group is being used, the loss of legal ownership or title to the asset, significant negative industry or economic trends or the presence of other factors that would indicate that the carrying amount of an asset or asset group is not recoverable. We consider a long-lived asset to be impaired if the estimated undiscounted future cash flows resulting from the use of the asset and its eventual disposition are not sufficient to recover the carrying value of the asset. If we deem an asset to be impaired, the amount of the impairment loss represents the excess of the asset's carrying value compared to its estimated fair value.
 
Warranty Accruals:    The Company warrants hardware product, generally for twelve months, and software, generally for 90 days. The software warranty entitles the customer to bug fixes but not software upgrades during the warranty period. The Company's methodology is to accrue warranty expense based on historical expense trends calculated as a percentage of product sales. Actual expenses are charged against the accrual in the period they are incurred. On a quarterly basis, the warranty accrual is analyzed for adequacy based on actual trends and subsequent adjustments are made as necessary.
 
Foreign Currency:    The functional currency for the Company's foreign subsidiaries is the local currency. Assets and liabilities of foreign subsidiaries are translated into U.S. dollars at the rates of exchange in effect at the end of the period. Revenue and expenses are translated into dollars at the average exchange rate during the period. Gains and losses from foreign currency translation are included in a separate account in stockholders' equity in the consolidated balance sheets.
 
Foreign exchange transaction gains and losses, substantially all of which relate to intercompany activity between the Company and its foreign subsidiaries, amounted to losses of $420,000, $180,000 and $45,000 in 2012, 2011 and 2010, respectively. These losses are included in other income (expense) in the accompanying consolidated statements of operations.
 
Loss Contingencies:     The Company is subject to the possibility of various loss contingencies arising in the ordinary course of business. Management considers the likelihood of loss related to an asset, or the incurrence of a liability, as well as its ability to reasonably estimate the amount of loss, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that an asset has been impaired or a liability has been incurred and the amount of loss can be reasonably estimated. The Company records a charge equal to the minimum estimated liability or a loss contingency only when both of the following conditions are met: (i) information available prior to issuance of the consolidated financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements, and (ii) the range of loss can be reasonably estimated. The Company regularly evaluates current information available to determine whether such accruals should be adjusted and whether new accruals are required.
 
The Company provides disclosure when it is reasonably possible that a loss will be incurred or when it is reasonably possible that the amount of a loss will exceed the recorded provision. In such cases, management assesses whether a reasonable estimate of the loss or range of the loss can be made. If the loss or range of loss can be estimated, the Company does so. If management concludes the loss or range of loss cannot be estimated, the Company discloses its conclusion in that regard.
 
From time to time, the Company is involved in disputes, litigation, and other legal actions. The Company is aggressively defending its current litigation matters. However, there are many uncertainties associated with any litigation and these actions or other third-party claims against the Company may cause the Company to incur costly litigation and/or substantial settlement charges. If any of those events were to occur, the Company's business, financial condition, results of operations, and cash flows could be adversely affected. The actual liability in any such matters may be materially different from the Company's estimates, which could result in the need to adjust the liability and record additional expenses.
 
Stock-based Compensation:    The Company recognizes stock-based compensation expense for all share-based payment awards including employee stock options and restricted stock awards, in accordance with FASB ASC Topic 718, Compensation - Stock Compensation. Stock-based compensation expense for expected-to-vest stock-based awards is valued under the single-option approach and amortized on a straight-line basis, net of estimated forfeitures. The value of the portion of the award that is ultimately expected to vest is recognized as expense over the requisite service periods in the Company's consolidated statements of operations for all periods presented.
 
The Company estimates the fair value of stock options granted using the Black-Scholes option-pricing formula and a single option award approach. The fair value is amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. The Company's computation of expected volatility is based on historical volatility commensurate with the expected term of the options. The risk-free interest rate used in the Black-Scholes option-pricing formula is based on the implied yield currently available on U.S. Treasury securities with an equivalent remaining term commensurate with the expected term of the options. The expected dividend assumption is based on the Company's current expectations about future dividends and the Company does not expect to pay out cash dividends in the foreseeable future. The Company estimated the expected term of options granted in fiscal 2012, 2011 and 2010 using vesting periods of awards and historical data such as past experience and post vesting cancellations. The Company believes these calculations provide reasonable estimates of expected life for stock-based awards to employees.
 
Comprehensive Loss -ASC 220 - Reporting Comprehensive Income establishes standards for the reporting and displaying of comprehensive income (loss) and its components. Comprehensive loss includes foreign currency translation adjustments, gross unrealized holding gains (losses) on available-for-sale securities, and reclassification adjustments for gains included in net loss.
 
Derivatives:    The Company does not use derivative financial instruments for speculative or trading purposes. In fiscal 2012, 2011 and 2010, the Company entered into foreign exchange forward contracts to hedge certain balance sheet exposures and intercompany balances against future movement in foreign exchange rates. Gains and losses on the foreign exchange contracts are included in other income(expense), net, which offset foreign exchange gains or losses from revaluation of foreign currency-denominated balance sheet items and intercompany balances. At March 30, 2012, there were no foreign exchange forward contracts outstanding.
 
Recently Issued Accounting Standards:  In June 2011, the FASB issued Accounting Standards Update ("ASU") No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income. This ASU amends ASC 220 to allow an entity the option to present income and comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. ASU 2011-05 eliminates the option to present the components of other comprehensive income as part of the statement of changes in stockholders' equity. In December 2011, the FASB issued guidance which indefinitely defers the guidance related to the presentation of reclassification adjustments. As the Company has historically presented a separate statement of comprehensive income (loss), we do not anticipate the adoption of this ASU will have any effect upon our financial statement presentation.
 
In May 2011, the FASB issued ASU No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs . This ASU represents the converged guidance of the FASB and the International Accounting Standards Board (the Boards) on fair value measurement. The Company adopted this new guidance, on a prospective basis, on December 31, 2011, the beginning of the fourth quarter of the Company's fiscal 2012. The adoption of ASU 2011-04 did not have a material effect upon the Company's consolidated financial statements for the year ended March 30, 2012.
 
In January 2010, the FASB issued new accounting guidance to amend and clarify existing guidance related to fair value measurements and disclosures: ASU No. 2010-06 Improving Disclosures about Fair Value Measurements. This guidance requires entities to separately present purchases, sales, issuances, and settlements in their reconciliation of Level 3 fair value measurements (i.e., to present such items on a gross basis rather than on a net basis), and clarifies existing disclosure requirements regarding the level of disaggregation and the inputs and valuation techniques used to measure fair value for measurements that fall within either Level 2 or Level 3 of the fair value hierarchy. The Company adopted the provisions of this guidance effective March 27, 2010, except for the requirement to disclose purchases, sales, issuances, and settlements related to Level 3 measurements, which the Company adopted on March 26, 2011, the beginning of the Company's fiscal 2012. The adoption of ASU 2010-06 did not have a material effect upon the Company's consolidated financial statements for the year ended March 30, 2012.
