| Summary of Significant Accounting Policies | Organization and Summary of Significant Accounting Policies Our Company NVIDIA is dedicated to advancing visual computing. NVIDIA has transformed into a specialized platform company that targets four large markets - Gaming, Professional Visualization, Datacenter and Automotive - where visual computing is essential and valued. Our two reportable segments - GPU and Tegra Processor - are based on a single underlying graphics architecture. From our proprietary processors, we have created platforms that address the four large markets where our visual computing expertise is critically important. We are focused on delivering value through PC, mobile and cloud architectures. Our vertical integration enables us to bring together hardware, system software, programmable algorithms, systems and services to create unique value for the markets we serve. Our GPU product brands are aimed at specialized markets including GeForce for gamers; Quadro for designers; Tesla for researchers and analysts focused on artificial intelligence, deep learning and big-data; and GRID for cloud-based visual computing users. We also integrate our GPUs into powerful mobile system-on-a-chip (SOC) processors, which drive supercomputing capabilities for tablets and online gaming and entertainment devices, as well as autonomous robots, drones and cars. Our Tegra brand integrates an entire computer onto a single chip, incorporating GPUs and multi-core CPUs with audio, video and input/output capabilities. Headquartered in Santa Clara, California, NVIDIA was incorporated in California in April 1993 and reincorporated in Delaware in April 1998. All references to “NVIDIA,” “we,” “us,” “our” or the “Company” mean NVIDIA Corporation and its subsidiaries, except where it is made clear that the term means only the parent company. Fiscal Year We operate on a 52- or a 53-week year, ending on the last Sunday in January. Fiscal year 2016 was a 53-week year with the extra week in the fiscal fourth quarter and fiscal years 2015 and 2014 were 52-week years. Principles of Consolidation Our consolidated financial statements include the accounts of NVIDIA Corporation and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States, or U.S. GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. On an on-going basis, we evaluate our estimates, including those related to revenue recognition, cash equivalents and marketable securities, accounts receivable, inventories, income taxes, goodwill, stock-based compensation, litigation, investigation and settlement costs, restructuring and other charges, and other contingencies. These estimates are based on historical facts and various other assumptions that we believe are reasonable. Revenue Recognition Product Revenue We recognize revenue from product sales when persuasive evidence of an arrangement exists, the product has been delivered, the price is fixed or determinable and collection of the related receivable is reasonably assured. For most sales, we use a binding purchase order and in certain cases we use a contractual agreement as evidence of an arrangement. We consider delivery to occur upon shipment provided title and risk of loss have passed to the customer. At the point of sale, we assess whether the arrangement fee is fixed or determinable and whether collection is reasonably assured. If we determine that collection of a fee is not reasonably assured, we defer the fee and recognize revenue at the time collection becomes reasonably assured, which is generally upon receipt of payment. For sales to certain distributors with rights of return for which the level of returns cannot be reasonably estimated, our policy is to defer recognition of revenue and related cost of revenue until the distributors resell the product and, in some cases, when customer return rights lapse. Our customer programs primarily involve rebates, which are designed to serve as sales incentives to resellers of our products in various target markets. We account for rebates as a reduction of revenue and recognize a liability for these rebates at the later of the date at which we record the related revenue or the date at which we offer the rebate. Unclaimed rebates are reversed to revenue. Our customer programs also include marketing development funds, or MDFs. MDFs represent monies paid to retailers, system builders, original equipment manufacturers, or OEMs, distributors, add-in card partners and other channel partners that are earmarked for market segment development and expansion and typically are designed to support our partners’ activities while also promoting NVIDIA products. We account for MDFs as a reduction of revenue and apply a breakage factor to certain types of MDF programs. We also record a reduction to revenue by establishing a sales return allowance for estimated product returns at the time revenue is recognized, based primarily on historical return rates. However, if product returns for a particular fiscal period exceed historical return rates we may determine that additional sales return allowances are required to properly reflect our estimated exposure for product returns. License and Development Revenue For license arrangements that require significant customization of our intellectual property components, we generally recognize the related revenue over the period that services are performed. For most license and service arrangements, we determine progress to completion based on actual cost incurred to date as a percentage of the estimated total cost required to complete the project. A provision for estimated losses on contracts is made in the period in which the loss becomes probable and can be reasonably estimated. Costs incurred in advance of revenue recognized are recorded as deferred costs on uncompleted contracts. If the amount billed exceeds the amount of revenue recognized, the excess amount is recorded as deferred revenue. For license arrangements that do not require significant customization but where we are obligated to provide further deliverables over the term of the license agreement, we record revenue over the life of the license term, with consideration received in advance of the performance period classified as deferred revenue. Royalty revenue is recognized related to the distribution or sale of products that use our technologies under license agreements with third parties. We recognize royalty revenue upon receipt of a confirmation of earned royalties and when collectability is reasonably assured from the applicable licensee. Restructuring and Other Charges Our restructuring and other charges include employee severance and related costs, the write-down of assets, and other exit costs. The severance and related costs include one-time termination benefits as well as certain statutory termination benefits or employee terminations under ongoing benefit arrangements. One-time termination benefits are recognized as a liability at estimated fair value when the approved plan of termination has been communicated to employees, unless employees must provide future service, in which case the benefits are recognized ratably over the future service period. Ongoing termination benefits arrangements are recognized as a liability at estimated fair value when the amount of such benefits becomes estimable and payment is probable. Any contract termination costs are recognized at estimated fair value when we terminate the contract in accordance with the contract terms. Other associated costs are recognized in the period the liability is incurred. Advertising Expenses We expense advertising costs in the period in which they are incurred. Advertising expenses for fiscal years 2016 , 2015 and 2014 were $ 17 million , $15 million and $13 million , respectively. Rent Expense We recognize rent expense on a straight-line basis over the lease period and accrue for rent expense incurred, but not paid. Product Warranties We generally offer limited warranty to end-users that ranges from one to three years for products in order to repair or replace products for any manufacturing defects or hardware component failures. Cost of revenue includes the estimated cost of product warranties that are calculated at the point of revenue recognition. Under limited circumstances, we may offer an extended limited warranty to customers for certain products. We also accrue for known warranty and indemnification issues if a loss is probable and can be reasonably estimated. Stock-based Compensation We estimate the fair value of employee stock options on the date of grant using a binomial model and recognize the expense using a straight-line attribution method over the requisite employee service period. We use the closing trading price of our common stock on the date of grant, minus a dividend yield discount, as the fair value of awards of restricted stock units, or RSUs, and performance stock units that are based on our corporate financial performance targets, or PSUs, and we use a Monte Carlo simulation on the date of grant to estimate the fair value of performance stock units that are based on market conditions, or market-based PSUs. The compensation expense for stock options, RSUs and market-based PSUs is recognized using a straight-line attribution method over the requisite employee service period while compensation expense for PSUs is recognized using an accelerated amortization model. We estimate the fair value of shares to be issued under our employee stock purchase plan, or ESPP, using the Black-Scholes model at the commencement of an offering period in March and September of each year. Stock-based compensation for our ESPP is expensed using an accelerated amortization model. Litigation, Investigation and Settlement Costs From time to time, we are involved in legal actions and/or investigations by regulatory bodies. We are aggressively defending our current litigation matters. However, there are many uncertainties associated with any litigation or investigation, and we cannot be certain that these actions or other third-party claims against us will be resolved without litigation, fines and/or substantial settlement payments. If that occurs, our business, financial condition and results of operations could be materially and adversely affected. If information becomes available that causes us to determine that a loss in any of our pending litigation, investigations or settlements is probable, and we can reasonably estimate the loss associated with such events, we will record the loss in accordance with U.S. GAAP. However, the actual liability in any such litigation or investigation may be materially different from our estimates, which could require us to record additional costs. Foreign Currency Remeasurement We use the United States dollar as our functional currency for all of our subsidiaries. Foreign currency monetary assets and liabilities are remeasured into United States dollars at end-of-period exchange rates. Non-monetary assets and liabilities such as property and equipment, and equity are remeasured at historical exchange rates. Revenue and expenses are remeasured at average exchange rates in effect during each period, except for those expenses related to the previously noted balance sheet amounts, which are remeasured at historical exchange rates. Gains or losses from foreign currency remeasurement are included in “Other income, net” in our Consolidated Statements of Income and to date have not been significant. The impact of gain or loss from foreign currency remeasurement included in determining other income, net was not significant for both fiscal year 2016 and 2015, and was a gain of $ 5 million for fiscal year 2014. Income Taxes We recognize federal, state and foreign current tax liabilities or assets based on our estimate of taxes payable or refundable in the current fiscal year by tax jurisdiction. We recognize federal, state and foreign deferred tax assets or liabilities, as appropriate, for our estimate of future tax effects attributable to temporary differences and carryforwards; and we record a valuation allowance to reduce any deferred tax assets by the amount of any tax benefits that, based on available evidence and judgment, are not expected to be realized. United States income tax has not been provided on a portion of earnings of our non-U.S. subsidiaries to the extent that such earnings are considered to be indefinitely reinvested. Our calculation of deferred tax assets and liabilities is based on certain estimates and judgments and involves dealing with uncertainties in the application of complex tax laws. Our estimates of deferred tax assets and liabilities may change based, in part, on added certainty or finality to an anticipated outcome, changes in accounting standards or tax laws in the United States, or foreign jurisdictions where we operate, or changes in other facts or circumstances. In addition, we recognize liabilities for potential United States and foreign income tax contingencies based on our estimate of whether, and the extent to which, additional taxes may be due. If we determine that payment of these amounts is unnecessary or if the recorded tax liability is less than our current assessment, we may be required to recognize an income tax benefit or additional income tax expense in our financial statements accordingly. As of January 31, 2016, we had a valuation allowance of $272 million related to state and certain foreign deferred tax assets that management determined are not likely to be realized due, in part, to projections of future taxable income and potential utilization limitations of tax attributes acquired as a result of stock ownership changes. To the extent realization of the deferred tax assets becomes more-likely-than-not, we would recognize such deferred tax asset as an income tax benefit during the period. We recognize excess tax benefit related to stock-based compensation as a credit to shareholders' equity if and when realized. In determining if and when excess tax benefits have been realized, we have elected to utilize the with-and-without approach with respect to such excess tax benefits. We have also elected to ignore the indirect tax effects of stock-based compensation deductions for financial and accounting reporting purposes, and specifically to recognize the full effect of the research tax credit in income from operations. We recognize the benefit from a tax position only if it is more-likely-than-not that the position would be sustained upon audit based solely on the technical merits of the tax position. Our policy is to include interest and penalties related to unrecognized tax benefits as a component of income tax expense. Please refer to Note 13 of these Notes to the Consolidated Financial Statements for additional information. Comprehensive Income Comprehensive income consists of net income and other comprehensive income (loss). Other comprehensive income (loss) components include unrealized gains (losses) on available-for-sale securities and the net change in fair value of our interest rate swap, net of tax. Net Income Per Share Basic net income per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted average number of common and potentially dilutive shares outstanding during the period, using the treasury stock method. Under the treasury stock method, the effect of stock options outstanding is not included in the computation of diluted net income per share for periods when their effect is anti-dilutive. Additionally, we issued convertible notes with a net settlement feature that requires us, upon conversion, to settle the principal amount of debt for cash and the conversion premium for cash or shares of our common stock. Our convertible notes, note hedges, and related warrants contain various conversion features, which are further described in Note 11 of these Notes to the Consolidated Financial Statements. The potentially dilutive shares resulting from the convertible notes and warrants under the treasury stock method will be included in the calculation of diluted income per share when their inclusion is dilutive. However, unless actually exercised, the note hedges will not be included in the calculation of diluted net income per share, as their pre-exercised effect would be anti-dilutive under the treasury stock method. Cash and Cash Equivalents We consider all highly liquid investments that are readily convertible into cash and have an original maturity of three months or less at the time of purchase to be cash equivalents. As of January 31, 2016 and January 25, 2015 , our cash and cash equivalents were $596 million and $497 million , respectively, including $ 43 million and $132 million , respectively, invested in money market funds. Marketable Securities Marketable securities consist primarily of highly liquid investments with maturities of greater than three months when purchased. We generally classify our marketable securities at the date of acquisition as available-for-sale. These securities are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of shareholders’ equity, net of tax. The fair value of interest-bearing securities includes accrued interest. Any unrealized losses which are considered to be other-than-temporary impairments are recorded in the other income and expense section of our Consolidated Statements of Income. Realized gains and losses on the sale of marketable securities are determined using the specific-identification method and recorded in the other income and expense section of our Consolidated Statements of Income. All of our available-for-sale investments are subject to a periodic impairment review. We record a charge to earnings when a decline in fair value is significantly below cost basis and judged to be other-than-temporary, or have other indicators of impairments. If the fair value of an available-for-sale debt instrument is less than its amortized cost basis, an other-than-temporary impairment is triggered in circumstances where (1) we intend to sell the instrument, (2) it is more likely than not that we will be required to sell the instrument before recovery of its amortized cost basis, or (3) a credit loss exists where we do not expect to recover the entire amortized cost basis of the instrument. In these situations, we recognize an other-than-temporary impairment in earnings equal to the entire difference between the debt instruments’ amortized cost basis and its fair value. For available-for-sale debt instruments that are considered other-than-temporarily impaired due to the existence of a credit loss, if we do not intend to sell and it is not more likely than not that we will not be required to sell the instrument before recovery of its remaining amortized cost basis (amortized cost basis less any current-period credit loss), we separate the amount of the impairment into the amount that is credit related and the amount due to all other factors. The credit loss component is recognized in earnings while loss related to all other factors is recorded in accumulated other comprehensive income (loss). Fair Value of Financial Instruments The carrying value of cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to their relatively short maturities as of January 31, 2016 and January 25, 2015 . Marketable securities are comprised of available-for-sale securities that are reported at fair value with the related unrealized gains (losses) included in accumulated other comprehensive income (loss), a component of shareholders’ equity, net of tax. Fair value of the marketable securities is determined based on quoted market prices. Derivative instruments are recognized as either assets or liabilities and are measured at fair value. The accounting for changes in the fair value of a derivative depends on the intended use of the derivative and the resulting designation. For derivative instruments designated as fair value hedges, the gains (losses) are recognized in earnings in the periods of change together with the offsetting losses (gains) on the hedged items attributed to the risk being hedged. For derivative instruments designated as cash-flow hedges, the effective portion of the gains (losses) on the derivatives is initially reported as a component of other comprehensive income (loss) and is subsequently recognized in earnings when the hedged exposure is recognized in earnings. Concentration of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash equivalents, marketable securities, accounts receivable, note hedge and interest rate swap. Our investment policy requires the purchase of high grade investment securities, the diversification of asset type and includes certain limits on our portfolio duration. All marketable securities are held in our name, managed by several investment managers and held by one major financial institution under a custodial arrangement. Accounts receivable from significant customers, those representing 10% or more of total accounts receivable, aggregated approximately 21% of our accounts receivable balance from one customer as of January 31, 2016 and 30% of our account receivable balance from two customers as of January 25, 2015 . We perform ongoing credit evaluations of our customers’ financial condition and maintain an allowance for potential credit losses. This allowance consists of an amount identified for specific customers and an amount based on overall estimated exposure. Our overall estimated exposure excludes amounts covered by credit insurance and letters of credit. Accounts Receivable We maintain an allowance for doubtful accounts receivable for estimated losses resulting from the inability of our customers to make required payments. We determine this allowance, which consists of an amount identified for specific customer issues as well as an amount based on overall estimated exposure. Factors impacting the allowance include the level of gross receivables, the financial condition of our customers and the extent to which balances are covered by credit insurance or letters of credit. Inventories Inventory cost is computed on an adjusted standard basis, which approximates actual cost on an average or first-in, first-out basis. Inventory costs consist primarily of the cost of semiconductors purchased from subcontractors, including wafer fabrication, assembly, testing and packaging, manufacturing support costs, including labor and overhead associated with such purchases, final test yield fallout, and shipping costs, as well as the cost of purchased memory products and other component parts. We charge cost of sales for inventory provisions to write down our inventory to the lower of cost or estimated market value or to completely write off obsolete or excess inventory. Most of our inventory provisions relate to the write-off of excess quantities of products, based on our inventory levels and future product purchase commitments compared to assumptions about future demand and market conditions. Once inventory has been written-off or written-down, it creates a new cost basis for the inventory that is not subsequently written-up. Property and Equipment Property and equipment are stated at cost. Depreciation of property and equipment is computed using the straight-line method based on the estimated useful lives of the assets, generally three to five years. Once an asset is identified for retirement or disposition, the related cost and accumulated depreciation or amortization are removed, and a gain or loss is recorded. The estimated useful lives of our buildings are up to twenty five years. Depreciation expense includes the amortization of assets recorded under capital leases. Leasehold improvements and assets recorded under capital leases are amortized over the shorter of the expected lease term or the estimated useful life of the asset. Goodwill Goodwill is subject to our annual impairment test during the fourth quarter of our fiscal year, or earlier if indicators of potential impairment exist. For the purposes of completing our impairment test, we perform either a qualitative or a quantitative analysis on a reporting unit basis. For those reporting units where a significant change or event has occurred, where potential impairment indicators exist, or for which we have not performed a quantitative assessment recently, we utilize a two-step quantitative assessment to testing goodwill for impairment. The first step tests for possible impairment by applying a fair value-based test by weighing the results from the income approach and the market approach. The second step, if necessary, measures the amount of such impairment by applying fair value-based tests to individual assets and liabilities. Please refer to Note 4 of these Notes to the Consolidated Financial Statements for additional information. Intangible Assets Intangible assets primarily represent rights acquired under technology licenses, patents, acquired intellectual property, trademarks and customer relationships and are subject to an annual impairment test. We currently amortize our intangible assets with definitive lives over periods ranging from one to ten years using a method that reflects the pattern in which the economic benefits of the intangible asset are consumed or otherwise used up or, if that pattern cannot be reliably determined, using a straight-line amortization method. Impairment of Long-Lived Assets Long-lived assets, such as property and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset, or asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset, or asset group to estimated undiscounted future cash flows expected to be generated by the asset, or asset group. If the carrying amount of an asset or asset group exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset or asset group exceeds the estimated fair value of the asset or asset group. Fair value is determined based on the estimated discounted future cash flows expected to be generated by the asset or asset group. Assets and liabilities to be disposed of would be separately presented in the Consolidated Balance Sheet and the assets would be reported at the lower of the carrying amount or fair value less costs to sell, and would no longer be depreciated. Accounting for Asset Retirement Obligations We account for asset retirement obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. As of January 31, 2016 and January 25, 2015 , our asset retirement obligations to return the leasehold improvements at our headquarters facility and certain laboratories at our domestic and international facilities to their original condition upon lease termination were $2 million and $7 million , respectively. Adoption of New and Recently Issued Accounting Pronouncements In February 2016, the Financial Accounting Standards Board, or FASB, issued an accounting standards update regarding the accounting for leases. The objective of the update is to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet for leases with a lease term of more than 12 months. In addition, the update will require additional disclosures regarding key information about leasing arrangements. Under existing guidance, operating leases are not recorded as lease assets and lease liabilities on the balance sheet. The update will be effective for us beginning in our first quarter of fiscal year 2020, with early adoption permitted. We are currently evaluating the impact of the adoption of this accounting guidance on our consolidated financial statements, however, we expect the adoption of this accounting guidance to result in an increase in lease assets and a corresponding increase in lease liabilities on our Consolidated Balance Sheets. In November 2015, the FASB issued an accounting standards update to simplify the presentation of deferred income taxes. The new guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The update is effective for fiscal years beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is permitted and may be applied either prospectively or retrospectively. We adopted this update in the fourth quarter of fiscal year 2016 on a prospective basis. Prior reporting periods were not retrospectively adjusted. The adoption of this guidance had no impact on our Consolidated Statements of Income. In July 2015, the FASB issued an accounting standards update for the subsequent measurement of inventory. The amended guidance requires entities to measure inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The requirement would replace the current lower of cost or market evaluation. The update is effective for us beginning in our first quarter of fiscal year 2018, with early adoption permitted to be applied prospectively. The adoption of this accounting guidance is not currently expected to have a material impact on our consolidated financial statements. In April 2015, the FASB issued an accounting standards update that requires an entity to present debt issuance costs on the balance sheet as a direct deduction from the related debt liability as opposed to an asset. Amortization of the costs will continue to be reported as interest expense. The update is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2015. Early adoption is permitted for financial statements that have not been previously issued, and the new guidance would be applied retrospectively to all prior periods presented. The update will be effective for us beginning in our first quarter of fiscal year 2017. The adoption of this accounting guidance is not currently expected to have a material impact on our consolidated financial statements. In April 2015, the FASB issued an accounting standards update that provides clarification on whether a cloud computing arrangement includes a software license. If a software license is included, the customer should account for the license consistent with its accounting for other software licenses. If a software license is not included, the arrangement should be accounted for as a service contract. The update is effective for reporting periods beginning after December 15, 2015, with early adoption permitted. Companies can elect to adopt the standard update prospectively or retrospectively to arrangements entered into, or materially modified, after the effective date. The update will be effective for us beginning in our first quarter of fiscal year 2017. We expect the adoption of this accounting guidance to result in an increase in software license assets and related depreciation expense, and a corresponding decrease in prepaid service contract assets and related service contract expense in our consolidated financial statements. In May 2014, the FASB issued an accounting standards update that creates a single source of revenue guidance under U.S. GAAP for all companies, in all industries, effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. On July 9, 2015, the FASB voted to defer the effective date by one year, such that the new standard will be effective for us beginning in our first quarter of fiscal year 20 |
