Description of Business and Significant Accounting Policies | 1. Description of Business and Significant Accounting Policies Description of Business —NetApp, Inc. (we, us, or the Company) provide software, systems and services to manage and store computer data. We enable enterprises, service providers, governmental organizations, and original equipment manufacturers to envision, deploy and evolve their information technology environments and to reduce costs and risk while driving growth and success for their organizations. Fiscal Year — Our fiscal year is reported on a 52- or 53-week year that ends on the last Friday in April. Our fiscal years 2015, 2014 and 2013 ended on April 24, 2015, April 25, 2014 and April 26, 2013, respectively, and were each 52-week years. An additional week is included in the first fiscal quarter approximately every six years to realign fiscal months with calendar months. Fiscal year 2016 will span 53 weeks, with a 14th week included in the first quarter of fiscal 2016. Unless otherwise stated, references to particular years, quarters, months and periods refer to the Company’s fiscal years ended on the last Friday of April and the associated quarters, months and periods of those fiscal years. Principles of Consolidation — The consolidated financial statements include the Company and its subsidiaries. Intercompany accounts and transactions are eliminated in consolidation. Accounting Change — In our fourth quarter of fiscal 2015, we adopted an Accounting Standards Update (ASU) that simplifies the presentation of debt issuance costs by requiring them to be presented as a direct deduction from the carrying amount of the related debt liability, rather than as a deferred charge, consistent with debt discounts. The new guidance was applied on a retrospective basis to April 25, 2014. The amended presentation of debt issuance costs resulted in a $7.5 million and $5.4 million reduction of each of other non-current assets and long-term debt in the consolidated balance sheets as of April 24, 2015 and April 25, 2014, respectively. Use of Estimates — The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include, but are not limited to, revenue recognition, reserves and allowances; inventory valuation and purchase order accruals; valuation of goodwill and intangibles; restructuring reserves; product warranties; employee benefit accruals; stock-based compensation; loss contingencies; investment impairments; income taxes and fair value measurements. Actual results could differ materially from those estimates. Cash Equivalents — We consider all highly liquid debt investments with original maturities of three months or less at the time of purchase to be cash equivalents. Available-for-Sale Investments — We classify our investments in debt securities as available-for-sale investments. Debt securities primarily consist of corporate bonds, U.S. Treasury and government debt securities and certificates of deposit. These available-for-sale investments are primarily held in the custody of a major financial institution. A specific identification method is used to determine the cost basis of debt securities sold. These investments are recorded in the consolidated balance sheets at fair value. Unrealized gains and temporary losses, net of related taxes, are included in accumulated other comprehensive income (loss) (AOCI). Upon realization, those amounts are reclassified from AOCI to earnings. The amortization of premiums and discounts on the investments are included in our results of operations. Realized gains and losses on our available-for-sale investments are calculated based on the specific identification method. We classify our investments as current or noncurrent based on the nature of the investments and their availability for use in current operations. Other-than-Temporary Impairments on Investments — All of our available-for-sale investments are subject to periodic impairment review. When the fair value of a debt security is less than its amortized cost, it is deemed impaired, and we assess whether the impairment is other-than-temporary. An impairment is considered other-than-temporary if (i) we have the intent to sell the security, (ii) it is more likely than not that we will be required to sell the security before recovery of the entire amortized cost basis, or (iii) we do not expect to recover the entire amortized cost basis of the security. If impairment is considered other-than-temporary based on condition (i) or (ii) described above, the entire difference between the amortized cost and the fair value of the debt security is recognized in the results of operations. If an impairment is considered other-than-temporary based on condition (iii) described above, 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 debt security) is recognized in earnings, and the amount relating to all other factors is recognized in other comprehensive income (OCI). For our auction rate securities (ARSs), impairment was determined based on fair value and marketability of these investments. The valuation models used to estimate fair value include numerous assumptions such as assessments of the underlying structure of each security, expected cash flows, discount rates, trading activity in the secondary market for similar securities, credit ratings, workout periods, and overall capital market liquidity. Inventories — Inventories are stated at the lower of cost or market, which approximates actual cost on a first-in, first-out basis. We write down excess and obsolete inventory based on the difference between the cost of inventory and the estimated net realizable value based upon assumptions about future demand forecasts and market conditions. At the point of a loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts or circumstances do not result in the restoration or increase in that newly established basis. In addition, we record a liability for firm, non-cancelable and unconditional purchase commitments with contract manufacturers and suppliers for quantities in excess of our future demand forecasts consistent with our valuation of excess and obsolete inventory. Property and Equipment — Property and equipment are recorded at cost. Depreciation and amortization is computed using the straight-line method, generally over the following periods:
|  | Depreciation Life
Buildings and improvements |  | 10 to 40 years
Furniture and fixtures |  | 5 years
Computer, production, engineering and other equipment |  | 2 to 3 years
Computer software |  | 3 to 5 years
Leasehold improvements |  | Shorter of remaining lease term or useful life
Construction in progress will be depreciated over the estimated useful lives of the respective assets when they are ready for use. We capitalize interest on significant facility assets under construction and on significant software development projects. Software Development Costs — The costs for the development of new software products and substantial enhancements to existing software products are expensed as incurred until technological feasibility has been established, at which time any additional costs would be capitalized in accordance with the accounting guidance for software. Because our current process for developing software is essentially completed concurrently with the establishment of technological feasibility, which occurs upon the completion of a working model, no costs have been capitalized for any of the periods presented. Internal-Use Software Development Costs — We capitalize qualifying costs, which are incurred during the application development stage, for computer software developed or obtained for internal-use and amortize them over the software’s estimated useful life. Business Combinations — We recognize identifiable assets acquired and liabilities assumed at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions as a part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that we identify adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations. Goodwill and Purchased Intangible Assets — Goodwill is recorded when the consideration paid for an acquisition exceeds the fair value of net tangible and intangible assets acquired. Purchased intangible assets are amortized on a straight-line basis over their economic lives of three to six years for developed technology, two to eight years for customer contracts/relationships, two to three years for covenants not to compete and two to seven years for trademarks and trade names as we believe this method most closely reflects the pattern in which the economic benefits of the assets will be consumed. The carrying value of goodwill is tested for impairment on an annual basis in the fourth quarter of our fiscal year, or more frequently if we believe indicators of impairment exist. Triggering events for impairment reviews may be indicators such as adverse industry or economic trends, restructuring actions, lower projections of profitability, or a sustained decline in our market capitalization. The performance of the test involves a two-step process. The first step requires comparing the fair value of each of our reporting units to its net book value, including goodwill. We have three reporting units, the fair values of which are determined based on an allocation of our entity level market capitalization, as determined through quoted market prices. A potential impairment exists if the fair value of the reporting unit is lower than its net book value. The second step of the process is only performed if a potential impairment exists, and it involves determining the difference between the fair value of the reporting unit’s net assets other than goodwill and the fair value of the reporting unit. If that difference is less than the net book value of goodwill, an impairment exists and is recorded. We have not been required to perform this second step of the process because the fair values of each of our reporting units have exceeded their respective net book values in fiscal 2015, 2014 and 2013. Impairment of Long-Lived Assets — We review the carrying values of long-lived assets whenever events and circumstances, such as reductions in demand, lower projections of profitability, significant changes in the manner of our use of acquired assets, or significant negative industry or economic trends, indicate that the net book value of an asset may not be recovered through expected future cash flows from its use and eventual disposition. If this review indicates that there is an impairment, the impaired asset is written down to its fair value, which is typically calculated using: (i) quoted market prices and/or (ii) expected future cash flows utilizing a discount rate. Our estimates regarding future anticipated net revenue and cash flows, the remaining economic life of the products and technologies, or both, may differ from those used to assess the recoverability of assets. In that event, impairment charges or shortened useful lives of certain long-lived assets may be required, resulting in charges to our consolidated statements of operations when such determinations are made. Derivative Instruments — Our derivative instruments consist of foreign currency exchange contracts as described below: Balance Sheet Hedges — We utilize foreign currency exchange forward and option contracts to hedge against the short-term impact of foreign currency exchange rate fluctuations related to certain foreign currency denominated monetary assets and liabilities, primarily intercompany receivables and payables. These derivative instruments are not designated as hedging instruments and do not subject us to material balance sheet risk due to exchange rate movements because the gains and losses on these contracts are intended to offset the gains and losses in the underlying foreign currency denominated monetary assets and liabilities being hedged and the net amount is included in earnings. Cash Flow Hedges — We use foreign currency exchange forward contracts to hedge foreign currency exchange exposures related to forecasted sales transactions denominated in certain foreign currencies. These derivative instruments are designated and qualify as cash flow hedges and in general, closely match the underlying forecasted transactions in duration. The contracts are carried in the consolidated balance sheets at fair value, and the effective portion of the contracts’ gains and losses resulting from changes in fair value is recorded in AOCI until the forecasted transaction is recognized in the consolidated statements of operations. When the forecasted transactions occur, we reclassify the related gains or losses on the cash flow hedges into net revenues. If the underlying forecasted transactions do not occur, or it becomes probable that they will not occur within the defined hedge period, the gains or losses on the related cash flow hedges are reclassified from AOCI and recognized immediately in earnings. We measure the effectiveness of hedges of forecasted transactions on a monthly basis by comparing the fair values of the designated foreign currency exchange forward purchase contracts with the fair values of the forecasted transactions. Any ineffective portion of the derivative hedging gain or loss, as well as changes in the fair value of the derivative’s time value (which are excluded from the assessment of hedge effectiveness), are recognized in earnings. Factors that could have an impact on the effectiveness of our hedging programs include the accuracy of forecasts and the volatility of foreign currency markets. These programs reduce, but do not entirely eliminate, the impact of currency exchange movements. Currently, we do not enter into any foreign currency exchange forward contracts to hedge exposures related to firm commitments or nonmarketable investments. Cash flows from our derivative programs are included under operating activities in the consolidated statements of cash flows. Revenue Recognition — We recognize revenue when:
· | Persuasive evidence of an arrangement exists. Customarily we have a purchase order and/or contract prior to recognizing revenue on an arrangement from our end users, customers, value-added resellers or distributors.
· | Delivery has occurred. Our product is physically delivered to our customers. We typically do not allow for restocking rights with any of our value-added resellers or distributors. Products shipped with acceptance criteria or return rights are not recognized as revenue until all criteria are achieved. We do not recognize revenue if undelivered products or services exist that are essential to the functionality of the delivered product in an arrangement.
· | The fee is fixed or determinable. Arrangements with payment terms extending beyond our standard terms, conditions and practices are not considered to be fixed or determinable. Revenue from such arrangements is recognized at the earlier of customer payment or when the fees become due and payable. We typically do not allow for price-protection rights with any of our value-added resellers or distributors.
· | Collection is reasonably assured. If there is considerable doubt surrounding the creditworthiness of a customer at the outset of an arrangement, the associated revenue is deferred and recognized upon cash receipt.
The hardware systems and software components essential to the functionality of the hardware systems are considered non-software deliverables and therefore are not subject to industry-specific software revenue recognition guidance. Our product revenues also include revenues from the sale of non-essential software products. Non-essential software sales generally include a perpetual license to our software. Non-essential software sales are subject to the industry-specific software revenue recognition guidance. Our multiple element arrangements may include our systems, software maintenance, hardware maintenance and other services. Software maintenance contracts entitle our customers to receive unspecified product upgrades and enhancements on a when-and-if-available basis, and patch releases. Hardware maintenance services include contracts for extended warranty, technical support and minimum response times. Other services include professional services and customer education and training services. Revenues from software maintenance and hardware maintenance services are recognized ratably over the contractual term, generally from one to five years. We also offer extended warranty contracts (which extend our standard parts warranty and may include premium hardware maintenance) at the end of the original warranty term; revenues from these contracts are recognized ratably over their respective contract term. We sell professional services either on a time and materials basis or under fixed price projects; we recognize revenue for these services as they are performed. For multiple element arrangements, we allocate revenue to the software deliverables and the non-software deliverables as a group based on the relative selling prices of all of the deliverables in the arrangement. The selling price for each element is based upon the following selling price hierarchy: vendor specific objective evidence of selling price (VSOE) if available, third party evidence (TPE) if VSOE is not available, or estimated selling price (ESP) if neither VSOE nor TPE are available. ESP is generally evidenced by a majority of historical transactions falling within a reasonable price range. We also consider multiple factors, including, but not limited to, cost of products, gross margin objectives, historical pricing practices, type of customer and distribution channels. For our non-software deliverables, we generally allocate the arrangement consideration based on the relative selling price of the deliverables using ESP. For our software maintenance services, we generally use VSOE. When we are unable to establish VSOE for our software maintenance services, we use ESP in our allocation of arrangement consideration. VSOE is based upon the normal pricing and discounting practices for those services when sold separately. VSOE is generally evidenced by a substantial majority of historical stand-alone transactions falling within a reasonably narrow range. In addition, we consider major service type, customer type, and other variables in determining VSOE. When VSOE cannot be established, we attempt to establish the selling price of each element based on third party evidence of selling price (TPE). Generally, we are not able to determine TPE because our go-to-market strategy differs from that of our peers and our offerings contain a significant level of differentiation such that the comparable pricing of products with similar functionality cannot be obtained. We regularly review VSOE, TPE, and ESP and maintain internal controls over the establishment and updates of these estimates. For our software deliverables, we use the residual method to recognize revenue when an arrangement includes one or more elements to be delivered at a future date and VSOE of all undelivered elements exists. Typically, only software maintenance, hardware maintenance and/or other services remain undelivered after the product is delivered. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the consideration is recognized as product revenues for delivered elements. If evidence of the fair value of one or more undelivered elements does not exist, all revenue is generally deferred until the earlier of when delivery of those elements occurs or when fair value can be established. In instances where the only undelivered element without fair value is software maintenance, the entire arrangement is recognized ratably over the maintenance period. We record reductions to revenue for estimated sales returns at the time of shipment. Sales returns are estimated based on historical sales returns, current trends, and our expectations regarding future experience. We monitor and analyze the accuracy of sales returns estimates by reviewing actual returns and adjust them for future expectations. Additionally, distributors and retail partners participate in various cooperative marketing and other programs, and we record estimated accruals and allowances for these programs. We accrue for these programs based on contractual terms and historical experience. Sales and value added taxes collected from customers and remitted to governmental authorities are presented on a net basis in the accompanying consolidated statements of operations. Product Warranties — Estimated future hardware and software warranty costs are recorded as a cost of product revenues at the time of product shipment, based on historical and projected warranty claim rates, historical and projected cost-per-claim and knowledge of specific product failures that are outside our typical experience. Factors that affect our warranty liability include the number of installed units subject to warranty protection, product failure rates, estimated material costs, estimated distribution costs and estimated labor costs. We assess the adequacy of our warranty accrual each quarter and adjust the amount as considered necessary. Foreign Currency Translation — For international subsidiaries whose functional currency is the local currency, gains and losses resulting from translation of these foreign currency financial statements into U.S. dollars are recorded in AOCI. For subsidiaries where the functional currency is the U.S. dollar, gains and losses resulting from the process of remeasuring foreign currency financial statements into U.S. dollars are included in other income (expense), net. Benefit Plans — We have a postretirement health care plan and various international defined benefit plans for certain of our employees. We record actuarial gains and losses within AOCI and amortize net gains or losses in excess of 10 percent of the greater of the market value of plan assets or the plans' projected benefit obligation on a straight-line basis over the remaining estimated service life of plan participants. The measurement date for all defined benefit plans is our fiscal year end. Stock-Based Compensation — We measure and recognize stock-based compensation for all stock-based awards, including employee stock options, restricted stock units (RSUs) and rights to purchase shares under our employee stock purchase plan (ESPP), based on their estimated fair value, and recognize the costs in our financial statements using the single option straight-line approach over the requisite service period for the entire award. The fair value of employee RSUs is equal to the market value of our common stock on the grant date of the award, less the present value of expected dividends during the vesting period, discounted at a risk-free interest rate. Calculating the fair value of employee stock options and the rights to purchase shares under the ESPP requires estimates and significant judgment. The fair value of each award is estimated on the grant date using the Black-Scholes option pricing model, and is not remeasured as a result of subsequent stock price fluctuations. Option-pricing models require the input of highly subjective assumptions, including the expected term of awards and the stock price volatility of the underlying stock of such awards. Our expected term assumption is based primarily on historical exercise and post-vesting forfeiture experience. Effective fiscal 2013, our stock price volatility assumption is based on a combination of our historical and implied volatility, whereas prior to fiscal 2013, we solely used implied volatility. In addition, the Black-Scholes option pricing model requires risk-free interest rates and expected dividends. The risk-free interest rates are based upon United States Treasury bills with equivalent expected terms, and the expected dividends are based on our history and expected dividend payouts. We estimate the number of stock-based awards that will be forfeited due to employee turnover. Our forfeiture assumption is primarily based on historical experience. In the event of a modification of stock-based awards, if the requisite service period of the modified award is longer than the requisite service period of the original award and, both before and after the modification, it is probable that the awards will vest, we recognize the unrecognized compensation cost remaining from the original award plus the incremental compensation cost, if any, as a result of a modification in its entirety over the remaining portion of the requisite service period of the modified award. Income Taxes — Deferred income tax assets and liabilities are provided for temporary differences that will result in tax deductions or income in future periods, as well as the future benefit of tax credit carryforwards. A valuation allowance reduces tax assets to their estimated realizable value. Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, we consider all available evidence, including past operating results, estimates of future taxable income, and the feasibility of tax planning strategies. In the event that we change our determination as to the amount of deferred tax assets that can be realized, we adjust our valuation allowance with a corresponding impact to the provision for income taxes in the period in which such determination is made. The accounting guidance for income taxes prescribes a comprehensive model for how a company should recognize, measure, present, and disclose in its financial statements uncertain tax positions that we have taken or expect to take on a tax return (including a decision whether to file or not to file a return in a particular jurisdiction). We recognize the tax liability for uncertain income tax positions on the income tax return based on the two-step process prescribed in the interpretation. The first step is to determine whether it is more likely than not that each income tax position would be sustained upon audit. The second step is to estimate and measure the tax benefit as the amount that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority. Estimating these amounts requires us to determine the probability of various possible outcomes. We evaluate these uncertain tax positions on a quarterly basis. The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying consolidated statement of operations. Determining the liability for uncertain tax positions requires us to make significant estimates and judgments as to whether, and the extent to which, additional taxes may be due based on potential tax audit issues in the U.S. and other tax jurisdictions throughout the world. Our estimates are based on the outcomes of previous audits, as well as the precedents set in cases in which others have taken similar tax positions to those taken by us. If we later determine that our exposure is lower or that the liability is not sufficient to cover our revised expectations, we adjust the liability and effect a related change in our tax provision during the period in which we make such a determination. Tax attributes related to the exercise of employee stock options are not realized until they result in a reduction of taxes payable. We do not include unrealized stock option attributes as components of our gross deferred tax assets and corresponding valuation allowance disclosures. Net Income per Share — Basic net income per share is computed by dividing income available to common stockholders by the weighted-average number of common shares outstanding. Diluted net income per share is computed giving effect to all dilutive potential shares that were outstanding during the period. Potential dilutive common shares can consist of outstanding stock options, shares to be purchased under our employee stock purchase plan and unvested RSUs, as well as outstanding warrants and shares to be issued upon the conversion of convertible notes. Treasury Stock — We account for treasury stock under the cost method. Upon the retirement of treasury stock, we allocate the value of treasury shares between common stock, additional paid-in capital and retained earnings.
