OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | 50% chance) that the indefinite-lived intangible asset is impaired. An organization may choose to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to calculating its fair value. Our indefinite-lived intangible assets are in-process research and development ("IPR&D") intangible assets. Due to cancellation of a specific IPR&D project, we recorded an impairment of $1 million in 2013. There were no impairments in fiscal years 2015 and 2014. In all other instances we used the qualitative test and concluded that it was more-likely-than-not that all other indefinite-lived assets were not impaired. Advertising. Advertising costs are expensed as incurred and amounted to $27 million in 2015 , $22 million in 2014 and $16 million in 2013 . Research and development. Costs related to the research, design and development of our products are charged to research and development expense as they are incurred. Sales taxes. Sales taxes collected from customers and remitted to governmental authorities are not included in our revenue. Investments. Cost method investments consisting of non-marketable equity securities are accounted for at historical cost. Trading securities are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in earnings. Investments designated as available-for-sale are reported at fair value, with unrealized gains and losses, net of tax, included in accumulated other comprehensive income. The Company assesses investments for impairment whenever events or changes in circumstances indicate that the carrying value of an investment may not be recoverable. In 2015, cost method investments with a carrying amount of $4 million were written down to their fair value of zero , resulting in an impairment charge of $4 million , which is included in other income (expense), net. There were no impairments recognized in 2014 and 2013. Net income per share. Basic net income per share is computed by dividing net income - the numerator - by the weighted average number of common shares outstanding - the denominator - during the period excluding the dilutive effect of stock options and other employee stock plans. Diluted net income per share gives effect to all potentially dilutive common stock equivalents outstanding during the period. The dilutive effect of share-based awards is reflected in diluted net income per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense, the tax benefits and shortfalls charged to additional paid-in capital and the dilutive effect of in-the-money options and non-vested restricted stock units. Under the treasury stock method, the amount the employee must pay for exercising stock options, unamortized share-based compensation expense and tax benefits or shortfalls are assumed proceeds to be used to repurchase hypothetical shares. Basic and diluted net income per share for all periods through October 31, 2014 is calculated using the shares distributed on November 1, 2014. See Note 7, "Net Income Per Share." Cash, cash equivalents and short term investments. We classify investments as cash equivalents if their original maturity or remaining maturity at the time of purchase is three months or less at the date of purchase. Cash equivalents are stated at cost, which approximates fair value. As of October 31, 2015 , approximately $338 million of our cash and cash equivalents was held outside of the U.S. in our foreign subsidiaries. Under current tax laws, most of the cash could be repatriated to the U.S., but it would be subject to U.S. federal and state income taxes, less applicable foreign tax credits. Our cash and cash equivalents mainly consist of short-term deposits held at major global financial institutions, investments in institutional money market funds, and similar short duration instruments with original maturities of 90 days or less. We continuously monitor the creditworthiness of the financial institutions and institutional money market funds in which we invest our funds. We classify investments as short-term investments if their original maturities are greater than three months and their remaining maturities are one year or less. Fair value of financial instruments. The carrying values of certain of our financial instruments including cash and cash equivalents, accounts receivable, accounts payable, and other accrued liabilities approximate fair value because of their short maturities. The fair value of long-term equity investments is determined using quoted market prices for those securities when available. For those long-term equity investments accounted for under the cost or equity method, their carrying value approximates their estimated fair value. The fair value of our long-term debt, calculated from quoted prices which are primarily Level 1 inputs under the accounting guidance fair value hierarchy, was below the carrying value by approximately $8 million as of October 31, 2015 and exceeded the carrying value by approximately $1 million as of October 31, 2014. The fair value of foreign currency contracts used for hedging purposes is estimated internally by using inputs tied to active markets. These inputs, for example, interest rate yield curves, foreign exchange rates, and forward and spot prices for currencies are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. See also Note 13, "Fair Value Measurements," for additional information on the fair value of financial instruments. Concentration of credit risk. Financial instruments that potentially subject us to significant concentration of credit risk include money market fund investments, time deposits and demand deposit balances. These investments are categorized as cash and cash equivalents and long-term investments. In addition, we have credit risk from derivative financial instruments used in hedging activities and accounts receivable. We invest in a variety of financial instruments and limit the amount of credit exposure with any one financial institution. We have a comprehensive credit policy in place and credit exposure is monitored on an ongoing basis. Credit risk with respect to our accounts receivable is diversified due to the large number of entities comprising our customer base and their dispersion across many different industries and geographies. Credit evaluations are performed on customers requiring credit over a certain amount. Credit risk is mitigated through collateral such as letters of credit, bank guarantees or payment terms like cash in advance. Credit evaluation is performed by an independent team to ensure proper segregation of duties. No single customer accounted for more than 10 percent of accounts receivable as of October 31, 2015 or 2014 . Derivative instruments. We are exposed to global foreign currency exchange rate risk in the normal course of business. We enter into foreign exchange hedging contracts, primarily forward contracts and purchased options to manage financial exposures resulting from changes in foreign currency exchange rates. Foreign currency exposures include committed and anticipated revenue and expense transactions (cash flow exposure) and assets and liabilities that are denominated in currencies other than the functional currency of the subsidiary (balance sheet exposure). For cash flow hedges, contracts are designed at inception as hedges of the related foreign currency exposures. For option contracts, we exclude time value from the measurement of effectiveness. We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking various hedge transactions at the inception of the hedge. This process includes linking all derivatives that are designated as cash flow hedges to specific forecasted transactions. We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the hedging instruments are highly effective in offsetting changes in cash flows of hedged items. Our foreign exchange hedging contracts generally mature within twelve months. In order to manage foreign currency exposures in a few limited jurisdictions we may enter into foreign exchange contracts that do not qualify for hedge accounting. In such circumstances, the local foreign currency exposure is offset by contracts owned by the parent company. We do not use derivative financial instruments for speculative trading purposes. All derivatives are recognized on the balance sheet at their fair values. For derivative instruments that are designated and qualify as a cash flow hedge, changes in the value of the effective portion of the derivative instrument is recognized in accumulated comprehensive income, a component of stockholders' equity. Amounts associated with cash flow hedges are reclassified and recognized in income when either the forecast transaction occurs or it becomes probable the forecast transaction will not occur. Derivatives not designated as hedging instruments are recorded on the balance sheet at their fair value and changes in the fair values are recorded in the income statement in the current period. Derivative instruments are subject to master netting arrangements and qualify for net presentation in the balance sheet. Changes in the fair value of the ineffective portion of derivative instruments are recognized in earnings in the current period. Cash flows from derivative instruments are classified in the statement of cash flows in the same category as the cash flows from the hedged or economically hedged item, primarily in operating activities. Property, plant and equipment. Property, plant and equipment are stated at cost less accumulated depreciation. Additions, improvements and major renewals are capitalized; maintenance, repairs and minor renewals are expensed as incurred. When assets are retired or disposed of, the assets and related accumulated depreciation and amortization are removed from our general ledger, and the resulting gain or loss is reflected in the combined and consolidated statement of operations. Buildings and improvements are depreciated over the lesser of their useful lives or the remaining term of the lease and machinery and equipment over three to ten years. We use the straight-line method to depreciate assets. Leases. We lease buildings, machinery and equipment under operating leases for original terms ranging generally from one to twenty-five years. Certain leases contain renewal options for periods up to ten years. Capitalized software. We capitalize certain internal and external costs incurred to acquire or create internal use software. Capitalized software is included in property, plant and equipment and is depreciated over three to five years once development is complete. Impairment of long-lived assets. We continually monitor events and changes in circumstances that could indicate carrying amounts of long-lived assets, including intangible assets, may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether the carrying value of such assets will be recovered through undiscounted expected" id="sjs-B4">OVERVIEW AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Overview. Keysight Technologies, Inc. ("we", "us", "Keysight" or the "company"), incorporated in Delaware on December 6, 2013, is a measurement company providing core electronic design and test solutions to communications and electronics industries. Separation from Agilent. On November 1, 2014, Keysight became an independent publicly-traded company through the distribution by Agilent Technologies Inc. ("Agilent") of 100 percent of the outstanding common stock of Keysight to Agilent's shareholders (the "Separation"). Each Agilent shareholder of record as of the close of business on October 22, 2014 received one share of Keysight common stock for every two shares of Agilent common stock held on the record date. Approximately 167 million shares of Keysight common stock were distributed on November 1, 2014 to Agilent shareholders. Keysight's Registration Statement on Form 10 was declared effective by the U.S. Securities and Exchange Commission ("SEC") on October 6, 2014. Keysight's common stock began trading "regular-way" under the ticker symbol "KEYS" on the New York Stock Exchange on November 3, 2014. Acquisition of Anite . On August 13, 2015 , we acquired all share capital of Anite plc ("Anite") for a cash price of approximately $558 million , net of $43 million of cash acquired. Anite is a U.K.-based global company and a leading supplier of wireless test solutions with strong software expertise. This acquisition expands our solutions offering in wireless research and development design and test. Coupled with Keysight's expertise in helping customers design and test hardware, we can now provide customers with comprehensive wireless solutions. Anite also has a Network Test business that brings innovative solutions that help deliver an outstanding experience for mobile users in the network. Anite results are included in Keysight's consolidated financial statements from the date of acquisition and are reported in the measurement solutions segment. For additional details related to the acquisition of Anite, see Note 3, "Acquisitions." Basis of presentation. We have prepared the accompanying financial statements pursuant to the rules and regulations of the SEC and in conformity with U.S. generally accepted accounting principles ("GAAP"). Our fiscal year end is October 31. Unless otherwise stated, all years and dates refer to our fiscal year. Agilent transferred substantially all of the assets and liabilities and operations of the electronic measurement business to Keysight in August 2014 ("the Capitalization"). Combined financial statements prior to the Capitalization were prepared on a stand-alone basis and were derived from Agilent’s consolidated financial statements and accounting records. Expenses were allocated to us using estimates that we consider to be a reasonable reflection of the utilization of services provided or the benefit received by us during the periods presented. Following the Capitalization, the consolidated financial statements include the accounts of the company and our wholly-owned subsidiaries. For the first half of fiscal 2015, Agilent provided some services on a transitional basis for a fee, which were partially offset by other income from Keysight services provided to Agilent. These services were received or provided under a transition services agreement. The net costs associated with the transition services agreement were not materially different than the historical costs that were allocated to us related to these same services. Management is responsible for the fair presentation of the accompanying combined and consolidated financial statements, prepared in accordance with U.S. GAAP, and has full responsibility for their integrity and accuracy. In the opinion of management, the accompanying combined and consolidated financial statements contain all adjustments necessary to present fairly our consolidated balance sheet and our combined and consolidated statement of operations, statement of comprehensive income, statement of cash flows and statement of equity for all periods presented. Principles of consolidation. The combined and consolidated financial statements include the accounts of the company and our wholly- and majority-owned subsidiaries. All significant inter-company transactions have been eliminated. All significant transactions between us and other businesses of Agilent are included in these combined and consolidated financial statements. All inter-company transactions prior to the Capitalization are considered to be effectively settled for cash in the combined and consolidated statement of cash flows at the time the transaction is recorded. Use of estimates. The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in our combined and consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management's best knowledge of current events and actions that may impact the company in the future, actual results may be different from the estimates. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are revenue recognition, inventory valuation, allocation methods and allocated expenses from Agilent prior to the separation, valuation of goodwill and other intangible assets, share-based compensation, retirement and post-retirement plan assumptions, restructuring, warranty and accounting for income taxes. Revenue recognition. We enter into agreements to sell products (hardware and/or software), services and other arrangements (multiple-element arrangements) that include combinations of products and services. We recognize revenue, net of trade discounts and allowances, provided that (1) persuasive evidence of an arrangement exists, (2) delivery has occurred, (3) the price is fixed or determinable and (4) collectability is reasonably assured. Delivery is considered to have occurred when title and risk of loss have transferred to the customer, for products, or when the service has been provided. We consider the price to be fixed or determinable when the price is not subject to refund or adjustments. We consider arrangements with extended payment terms not to be fixed or determinable, and accordingly we defer revenue until amounts become due. At the time of the transaction, we evaluate the creditworthiness of our customers to determine the appropriate timing of revenue recognition. Product revenue. Our product revenue is generated predominantly from the sales of various types of test equipment and associated software. Product revenue, including sales to resellers and distributors, is reduced for estimated returns, when appropriate. For sales or arrangements that include customer-specified acceptance criteria, including those where acceptance is required upon achievement of performance milestones, revenue is recognized after the acceptance criteria have been met. For products that include installation, if the installation meets the criteria to be considered a separate element, product revenue is recognized upon delivery, and recognition of installation revenue is delayed until the installation is complete. Otherwise, neither the product nor the installation revenue is recognized until the installation is complete. Where software is licensed separately, revenue is recognized when the software is delivered and has been transferred to the customer or, in the case of electronic delivery of software, when the customer is given access to the licensed software programs. We also evaluate whether collection of the receivable is probable, the fee is fixed or determinable and whether any other undelivered elements of the arrangement exist on which a portion of the total fee would be allocated based on vendor-specific objective evidence ("VSOE"). When VSOE is not available we then use third-party evidence ("TPE") or management's best estimate of selling price ("ESP"). Service revenue. Revenue from services includes repair and calibration services, extended warranty, customer and software support, consulting, training and education. Service revenue is deferred and recognized over the contractual period or as services are rendered and accepted by the customer. For example, customer support contracts are recognized rateably over the contractual period, while training revenue is recognized as the training is provided to the customer. In addition, the four revenue recognition criteria described above must be met before service revenue is recognized. Revenue recognition for arrangements with multiple deliverables. Our multiple-element arrangements are generally comprised of a combination of measurement instruments, installation or other start-up services, and/or software and/or support or services. Hardware and software elements are typically delivered at the same time and revenue is recognized upon delivery and acceptance, if required, once title and risk of loss pass to the customer. Delivery of installation, start-up services and other services varies based on the complexity of the equipment, staffing levels in a geographic location and customer preferences, and can range from a few days to a few months. Service revenue is deferred and recognized over the contractual period or as services are rendered and accepted by the customer. Revenue from the sale of software products that are not required to deliver the tangible product's essential functionality are accounted for under software revenue recognition rules which require VSOE of fair value to allocate revenue in a multiple-element arrangement. Our arrangements generally do not include any provisions for cancellation, termination, or refunds that would significantly impact recognized revenue. We evaluate the deliverables in our multiple-element arrangements and conclude that they are separate units of accounting if it is determined the delivered item or items have value to the customer on a standalone basis. For arrangements that include a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) has been determined to be probable and substantially in our control. We allocate revenue to each element in our multiple-element arrangements based upon their relative selling prices. We determine the selling price for each deliverable based on a selling price hierarchy. The selling price for a deliverable is based on VSOE if available, TPE if VSOE is not available, or ESP if neither VSOE nor TPE is available. Revenue allocated to each element is then recognized when the basic revenue recognition criteria for that element have been met. We use VSOE of selling price in the selling price allocation in all instances where it exists. VSOE of selling price for products and services is determined when a substantial majority of the selling prices fall within a reasonable range when sold separately. TPE of selling price can be established by evaluating largely interchangeable competitor products or services in standalone sales to similarly situated customers. As our products contain a significant element of proprietary technology and the solution offered differs substantially from that of competitors, it is difficult to obtain the reliable standalone competitive pricing necessary to establish TPE. ESP represents the best estimate of the price at which we would transact a sale if the product or service were sold on a standalone basis. We determine ESP for a product or service by using historical selling prices which reflect multiple factors including, but not limited to, customer type, geography, market conditions, competitive landscape, gross margin objectives and pricing practices. The determination of ESP is made through consultation with and approval by management. We may modify or develop new pricing practices and strategies in the future. As these pricing strategies evolve, changes may occur in ESP. The aforementioned factors may result in a different allocation of revenue to the deliverables in multiple-element arrangements, which may change the pattern and timing of revenue recognition for these elements but will not change the total revenue recognized for the arrangement. Shipping and handling costs. Our shipping and handling costs charged to customers are included in net revenue, and the associated expense is recorded in cost of products for all periods presented. Deferred revenue. Deferred revenue represents the amount that is allocated to undelivered elements in multiple-element arrangements. We limit the revenue recognized to the amount that is not contingent on the future delivery of products or services or meeting other specified performance conditions. In addition, service revenue is deferred and recognized over the contractual period or as services are rendered and accepted by the customer. Accounts receivable, net. Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Such accounts receivable have been reduced by an allowance for doubtful accounts, which is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based on customer specific experience and the aging of such receivables, among other factors. The allowance for doubtful accounts as of October 31, 2015 and 2014 was not material. We do not have any off-balance-sheet credit exposure related to our customers. Accounts receivable are also recorded net of product returns. Share-based compensation. Prior to our separation from Agilent, our employees historically participated in Agilent’s various incentive award plans, including employee stock options, restricted stock units and the employee stock purchases made under Agilent’s Employee Stock Purchase Plan ("Agilent's ESPP”) and we participated in Agilent’s share-based compensation plans and recorded share-based compensation expense based on the equity awards granted to our employees. We recorded compensation expense based on expenses for the awards to our employees as well as an allocation of Agilent’s corporate and shared services employee expenses. In 2015 , we accounted for share-based awards made to our employees and directors including employee stock option awards, restricted stock units, employee stock purchases made under Keysight's Employee Stock Purchase Plan ("Keysight's ESPP") and performance share awards under Keysight Technologies, Inc. Long-Term Performance ("Keysight's LTP") Program using the estimated grant date fair value method of accounting. In 2014 and 2013 , we accounted for share-based awards made to our employees and directors including employee stock option awards, restricted stock units, employee stock purchases made under Agilent's ESPP and performance share awards under Agilent Technologies, Inc. Long-Term Performance ("Agilent's LTP") Program using the estimated grant date fair value method of accounting. Under the fair value method, we recorded compensation expense for all share-based awards of $55 million in 2015 , $44 million in 2014 and $43 million in 2013 . Inventory. Inventory is valued at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of market value. We assess the valuation of our inventory on a periodic basis and make adjustments to the value for estimated excess and obsolete inventory based on estimates about future demand and actual usage. The excess balance determined by this analysis becomes the basis for our excess inventory charge. Our excess inventory review process includes analysis of sales unit forecasts, managing product rollovers and working with manufacturing to maximize recovery of excess inventory. Warranty. Our standard warranty term for most of our products from the date of delivery is typically three years, which increased from one year in the second quarter of fiscal 2013. We accrue for standard warranty costs based on historical trends in warranty charges as a percentage of net product revenue. The accrual is reviewed regularly and periodically adjusted to reflect changes in warranty cost estimates. Estimated warranty charges are recorded within cost of products at the time related product revenue is recognized. See Note 17, "Guarantees." We also sell extended warranties that provide warranty coverage beyond the standard warranty term. Revenue associated with extended warranties is deferred and recognized over the extended coverage period. Taxes on income. Income tax expense is based on income or loss before taxes. Deferred income taxes reflect the effect of temporary differences between asset and liability amounts that are recognized for financial reporting purposes and the amounts that are recognized for income tax purposes. These deferred taxes are measured by applying currently enacted tax laws. Valuation allowances are recognized to reduce deferred tax assets to the amount that is more likely than not to be realized. We account for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. We make adjustments to these reserves when facts and circumstances change, such as the closing of a tax audit or the refinement of an estimate due to new information. We classify the liability for unrecognized tax benefits as current to the extent that the company anticipates payment (or receipt) of cash within one year. Interest and penalties related to uncertain tax positions are recognized in the provision for income taxes. Given the number of years and numerous matters that remain subject to examination in various tax jurisdictions, we are unable to estimate the range of possible changes to the balance of our unrecognized tax benefits. Goodwill and other intangible assets. Goodwill is assessed for impairment at least annually in the fourth quarter, as of September 30, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. In accordance with the authoritative accounting guidance we have the option to perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If we determine this is the case, we are required to perform the two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss to be recognized. If we determine that it is more-likely-than-not that the fair value of the reporting unit is greater than its carrying amounts, the two-step goodwill impairment test is not required. As defined in the authoritative guidance, a reporting unit is an operating segment, or one level below an operating segment. Historically, we conducted our business in a single operating segment and reporting unit. In fiscal 2014, in conjunction with the planned separation, we implemented changes in our organizational structure which resulted in the formation of two reportable operating segments, which are also our reporting units. In fiscal year 2015, we assessed goodwill impairment by performing a qualitative test for our two reporting units, which consisted of our two segments, Measurement Solutions and Customer Support and Services. Based on the results of our testing, it was determined that it is more-likely-than-not that the fair value of the reporting units are greater than their carrying amounts. There was no impairment of goodwill during the years ended October 31, 2015, 2014 and 2013. Other intangible assets consist primarily of developed technologies, proprietary know-how, trademarks, and customer relationships and are amortized using the straight-line method over estimated useful lives ranging from 6 months to 15 years. No impairments of purchased intangible assets were recorded during the year ended October 31, 2015, 2014 and 2013. We review other intangible assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. The authoritative accounting guidance allows a qualitative approach for testing indefinite-lived intangible assets for impairment, similar to the impairment testing guidance for goodwill. It allows the option to first assess qualitative factors (events and circumstances) that could have affected the significant inputs used in determining the fair value of the indefinite-lived intangible asset. The qualitative factors assist in determining whether it is more-likely-than-not (i.e. > 50% chance) that the indefinite-lived intangible asset is impaired. An organization may choose to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to calculating its fair value. Our indefinite-lived intangible assets are in-process research and development ("IPR&D") intangible assets. Due to cancellation of a specific IPR&D project, we recorded an impairment of $1 million in 2013. There were no impairments in fiscal years 2015 and 2014. In all other instances we used the qualitative test and concluded that it was more-likely-than-not that all other indefinite-lived assets were not impaired. Advertising. Advertising costs are expensed as incurred and amounted to $27 million in 2015 , $22 million in 2014 and $16 million in 2013 . Research and development. Costs related to the research, design and development of our products are charged to research and development expense as they are incurred. Sales taxes. Sales taxes collected from customers and remitted to governmental authorities are not included in our revenue. Investments. Cost method investments consisting of non-marketable equity securities are accounted for at historical cost. Trading securities are reported at fair value, with gains or losses resulting from changes in fair value recognized currently in earnings. Investments designated as available-for-sale are reported at fair value, with unrealized gains and losses, net of tax, included in accumulated other comprehensive income. The Company assesses investments for impairment whenever events or changes in circumstances indicate that the carrying value of an investment may not be recoverable. In 2015, cost method investments with a carrying amount of $4 million were written down to their fair value of zero , resulting in an impairment charge of $4 million , which is included in other income (expense), net. There were no impairments recognized in 2014 and 2013. Net income per share. Basic net income per share is computed by dividing net income - the numerator - by the weighted average number of common shares outstanding - the denominator - during the period excluding the dilutive effect of stock options and other employee stock plans. Diluted net income per share gives effect to all potentially dilutive common stock equivalents outstanding during the period. The dilutive effect of share-based awards is reflected in diluted net income per share by application of the treasury stock method, which includes consideration of unamortized share-based compensation expense, the tax benefits and shortfalls charged to additional paid-in capital and the dilutive effect of in-the-money options and non-vested restricted stock units. Under the treasury stock method, the amount the employee must pay for exercising stock options, unamortized share-based compensation expense and tax benefits or shortfalls are assumed proceeds to be used to repurchase hypothetical shares. Basic and diluted net income per share for all periods through October 31, 2014 is calculated using the shares distributed on November 1, 2014. See Note 7, "Net Income Per Share." Cash, cash equivalents and short term investments. We classify investments as cash equivalents if their original maturity or remaining maturity at the time of purchase is three months or less at the date of purchase. Cash equivalents are stated at cost, which approximates fair value. As of October 31, 2015 , approximately $338 million of our cash and cash equivalents was held outside of the U.S. in our foreign subsidiaries. Under current tax laws, most of the cash could be repatriated to the U.S., but it would be subject to U.S. federal and state income taxes, less applicable foreign tax credits. Our cash and cash equivalents mainly consist of short-term deposits held at major global financial institutions, investments in institutional money market funds, and similar short duration instruments with original maturities of 90 days or less. We continuously monitor the creditworthiness of the financial institutions and institutional money market funds in which we invest our funds. We classify investments as short-term investments if their original maturities are greater than three months and their remaining maturities are one year or less. Fair value of financial instruments. The carrying values of certain of our financial instruments including cash and cash equivalents, accounts receivable, accounts payable, and other accrued liabilities approximate fair value because of their short maturities. The fair value of long-term equity investments is determined using quoted market prices for those securities when available. For those long-term equity investments accounted for under the cost or equity method, their carrying value approximates their estimated fair value. The fair value of our long-term debt, calculated from quoted prices which are primarily Level 1 inputs under the accounting guidance fair value hierarchy, was below the carrying value by approximately $8 million as of October 31, 2015 and exceeded the carrying value by approximately $1 million as of October 31, 2014. The fair value of foreign currency contracts used for hedging purposes is estimated internally by using inputs tied to active markets. These inputs, for example, interest rate yield curves, foreign exchange rates, and forward and spot prices for currencies are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. See also Note 13, "Fair Value Measurements," for additional information on the fair value of financial instruments. Concentration of credit risk. Financial instruments that potentially subject us to significant concentration of credit risk include money market fund investments, time deposits and demand deposit balances. These investments are categorized as cash and cash equivalents and long-term investments. In addition, we have credit risk from derivative financial instruments used in hedging activities and accounts receivable. We invest in a variety of financial instruments and limit the amount of credit exposure with any one financial institution. We have a comprehensive credit policy in place and credit exposure is monitored on an ongoing basis. Credit risk with respect to our accounts receivable is diversified due to the large number of entities comprising our customer base and their dispersion across many different industries and geographies. Credit evaluations are performed on customers requiring credit over a certain amount. Credit risk is mitigated through collateral such as letters of credit, bank guarantees or payment terms like cash in advance. Credit evaluation is performed by an independent team to ensure proper segregation of duties. No single customer accounted for more than 10 percent of accounts receivable as of October 31, 2015 or 2014 . Derivative instruments. We are exposed to global foreign currency exchange rate risk in the normal course of business. We enter into foreign exchange hedging contracts, primarily forward contracts and purchased options to manage financial exposures resulting from changes in foreign currency exchange rates. Foreign currency exposures include committed and anticipated revenue and expense transactions (cash flow exposure) and assets and liabilities that are denominated in currencies other than the functional currency of the subsidiary (balance sheet exposure). For cash flow hedges, contracts are designed at inception as hedges of the related foreign currency exposures. For option contracts, we exclude time value from the measurement of effectiveness. We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objective and strategy for undertaking various hedge transactions at the inception of the hedge. This process includes linking all derivatives that are designated as cash flow hedges to specific forecasted transactions. We also formally assess, both at the hedge’s inception and on an ongoing basis, whether the hedging instruments are highly effective in offsetting changes in cash flows of hedged items. Our foreign exchange hedging contracts generally mature within twelve months. In order to manage foreign currency exposures in a few limited jurisdictions we may enter into foreign exchange contracts that do not qualify for hedge accounting. In such circumstances, the local foreign currency exposure is offset by contracts owned by the parent company. We do not use derivative financial instruments for speculative trading purposes. All derivatives are recognized on the balance sheet at their fair values. For derivative instruments that are designated and qualify as a cash flow hedge, changes in the value of the effective portion of the derivative instrument is recognized in accumulated comprehensive income, a component of stockholders' equity. Amounts associated with cash flow hedges are reclassified and recognized in income when either the forecast transaction occurs or it becomes probable the forecast transaction will not occur. Derivatives not designated as hedging instruments are recorded on the balance sheet at their fair value and changes in the fair values are recorded in the income statement in the current period. Derivative instruments are subject to master netting arrangements and qualify for net presentation in the balance sheet.

Buildings and improvements are depreciated over the lesser of their useful lives or the remaining term of the lease and machinery and equipment over three to ten years. We use the straight-line method to depreciate assets. Leases. We lease buildings, machinery and equipment under operating leases for original terms ranging generally from one to twenty-five years. Certain leases contain renewal options for periods up to ten years. Capitalized software. We capitalize certain internal and external costs incurred to acquire or create internal use software. Capitalized software is included in property, plant and equipment and is depreciated over three to five years once development is complete. Impairment of long-lived assets. We continually monitor events and changes in circumstances that could indicate carrying amounts of long-lived assets, including intangible assets, may not be recoverable. When such events or changes in circumstances occur, we assess the recoverability of long-lived assets by determining whether the carrying value of such assets will be recovered through undiscounted expected |
