| Operations and summary of significant accounting policies | Operations and summary of significant accounting policies National Instruments Corporation is a Delaware corporation. We provide flexible application software and modular, multifunction hardware that users combine with industry-standard computers, networks and third party devices to create measurement, automation and embedded systems, which we refer to as “virtual instruments.” Our approach gives customers the ability to quickly and cost-effectively design, prototype and deploy unique custom-defined solutions for their design, control and test application needs. We offer hundreds of products used to create virtual instrumentation systems for general, commercial, industrial and scientific applications. Our products may be used in different environments, and consequently, specific application of our products is determined by the customer and generally is not known to us. We approach all markets with essentially the same products, which are used in a variety of applications from research and development to production testing, monitoring and industrial control. The following industries and applications are served by us worldwide: advanced research, automated test equipment, automotive, commercial aerospace, computers and electronics, consumer electronics, continuous process manufacturing, education, government/defense, medical research/pharmaceutical, power/energy, semiconductors, telecommunications and others. These financial statements have been prepared in accordance with U.S. generally accepted accounting principles. Principles of consolidation The Consolidated Financial Statements include the accounts of National Instruments Corporation and its subsidiaries. All significant intercompany accounts and transactions have been eliminated. Reclassifications As of December 31, 2017, we revised the presentation of Note 2 - Short-term investments of Notes to Consolidated Financial Statements. Certain amounts appearing in the previous year’s disclosures of short-term investments have been reclassified to conform to the current year’s presentation. Starting January 1, 2017, we began separately presenting the effect of exchange rate changes on cash and cash equivalents in our consolidated statements of cash flows due to growing operations in foreign currency environments. Amounts in the comparable prior periods have been reclassified to conform to the current period presentation. The reclassifications resulted in the disaggregation of the amount attributable to the “Effect of exchange rate changes on cash” of $(3.9) million and $(5.5) million, with a corresponding increase to “Net cash provided by operating activities”, for the twelve months ended December 31, 2016 and 2015, respectively. We believe the reclassification is immaterial to the consolidated financial statements. Use of estimates The preparation of our financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Our critical accounting policies are those that affect our financial statements materially and involve difficult, subjective or complex judgments by management. 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 materially different from the estimates. Cash and cash equivalents Cash and cash equivalents include cash and highly liquid investments with maturities of three months or less at the date of acquisition. Short-Term Investments We value our available-for-sale short-term investments based on pricing from third party pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. We classify all of our fixed income available-for-sale securities as having Level 2 inputs. The valuation techniques used to measure the fair value of our financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques. We believe all of these sources reflect the credit risk associated with each of our available-for-sale short-term investments. Short-term investments available-for-sale consist of debt securities issued by states of the U.S. and political subdivisions of the U.S., corporate debt securities and debt securities issued by U.S. government organizations and agencies. All short-term investments available-for-sale have contractual maturities of less than 52 months. Our investments are classified as available-for-sale and accordingly are reported at fair value, with unrealized gains and losses reported as other comprehensive income, a component of stockholders’ equity. Unrealized losses are charged against income when a decline in fair value is determined to be other than temporary. Investments with maturities beyond one year are classified as short-term based on their highly liquid nature and because such marketable securities represent the investment of cash that is available for current operations. The fair value of our short-term investments in debt securities at December 31, 2017 and December 31, 2016 was $122 million and $73 million, respectively. The increase was due to the net purchase of $48 million of short-term investments. We had $5.0 million U.S. dollar equivalent of corporate bonds that were denominated in Euro at December 31, 2017. We follow the guidance provided by FASB ASC 320 to assess whether our investments with unrealized loss positions are other than temporarily impaired. Realized gains and losses and declines in value judged to be other than temporary are determined based on the specific identification method and are reported in other income (expense), net, in our Consolidated Statements of Income. We did not identify or record any other-than-temporary impairments on our available-for-sale securities during 2017, 2016, and 2015. Accounts Receivable, net Accounts receivable are recorded net of allowances for sales returns of $2.1 million and $1.8 million at December 31, 2017 and 2016, respectively, and net of allowances for doubtful accounts of $2.9 million and $1.9 million at December 31, 2017 and 2016, respectively. A provision for estimated sales returns is made by reducing recorded revenue based on historical experience. We analyze historical returns, current economic trends and changes in customer demand of our products when evaluating the adequacy of our sales returns allowance. Our allowance for doubtful accounts is based on historical experience. We analyze historical bad debts, customer concentrations, customer creditworthiness and current economic trends when evaluating the adequacy of our allowance for doubtful accounts.
Inventories, net Inventories are stated at the lower-of-cost or net realizable value. Cost is determined using standard costs, which approximate the first-in first-out (“FIFO”) method. Cost includes the acquisition cost of purchased components, parts and subassemblies, in-bound freight costs, labor and overhead. Inventory is shown net of adjustment for excess and obsolete inventories of $16.4 million, $12.6 million and $10.1 million at December 31, 2017, 2016 and 2015, respectively.
Property and equipment, net Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which range from twenty to forty years for buildings, and three to seven years for purchased internal use software and for equipment which are each included in furniture and equipment. Leasehold improvements are depreciated over the shorter of the life of the lease or the asset. Intangible assets, net We capitalize costs related to the development and acquisition of certain software products. Capitalization of costs begins when technological feasibility has been established and ends when the product is available for general release to customers. Technological feasibility for our products is established when the product is available for beta release. Amortization is computed on an individual product basis for those products available for market and is recognized based on the product’s estimated economic life, generally three to six years. We use the services of outside counsel to search for, document, and apply for patents. Those costs, along with any filing or application fees, are capitalized. Costs related to patents which are abandoned are written off. Once a patent is granted, the patent costs are amortized ratably over the legal life of the patent, generally ten to seventeen years. At each balance sheet date, the unamortized costs for all intangible assets are reviewed by management and reduced to net realizable value when necessary. Goodwill The excess purchase price over the fair value of net assets acquired is recorded as goodwill. We have one operating segment and one reporting unit. Goodwill is tested for impairment on an annual basis, and between annual tests if indicators of potential impairment exist, using a fair-value-based approach based on the market capitalization of the reporting unit. We have historically performed our annual goodwill impairment test as of February 28 of each year. For the annual impairment test as of February 28, 2017, we performed a qualitative assessment of whether it was more likely than not that our reporting unit's fair value was less than its carrying amount. After completing the assessment, we determined that it was more likely than not that the estimated fair value of the reporting unit exceeded the carrying amount and that no impairment existed as of the assessment date. If we had concluded otherwise, a quantitative goodwill impairment test would have been required, which would have included a determination of the fair value of the reporting unit and a comparison of the fair value to its carrying value. Effective for the annual goodwill impairment test for 2018 and for future testing, we will perform the required annual test as of November 30 of each year rather than on February 28. We reperformed our annual goodwill impairment testing as of November 30, 2017 and determined that it was more likely than not that the estimated fair value of the reporting unit exceeded the carrying amount and that no impairment existed as of the assessment date. We do not believe that the change in the date of the annual goodwill impairment test is a material change in the method of applying an accounting principle nor do we expect that it will result in any delay, acceleration or impact to the results of the impairment testing. We believe this date is preferable because it aligns with the timing of our annual planning process which largely occurs during the fourth quarter. Retrospective application to prior periods is impracticable as we are unable to objectively determine, without the use of hindsight, the assumptions that would be used in those earlier periods. No impairment of goodwill was identified during 2017 and 2016. Goodwill is deductible for tax purposes in certain jurisdictions. Concentrations of credit risk We maintain cash and cash equivalents with various financial institutions located in many countries throughout the world. At December 31, 2017, we had $412 million in cash, cash equivalents and short-term investments. Our cash and cash equivalent balances are held in numerous financial institutions throughout the world, including substantial amounts held outside of the U.S., however, the majority of our short-term investments that are located outside of the U.S. are denominated in the U.S. dollar with the exception of $5 million U.S. dollar equivalent of corporate bonds that are denominated in Euro. The most significant of our operating accounts was our Hungarian Citibank operating account which held approximately $17 million or 6% of our total cash and cash equivalents at a bank that carried Baa1/BBB+/A ratings at December 31, 2017. The following table presents the geographic distribution of our cash, cash equivalents, and short-term investments as of December 31, 2017 (in millions):
The goal of our investment policy is to manage our investment portfolio to preserve principal and liquidity while maximizing the return on our investment portfolio through the full investment of available funds. We place our cash investments in instruments that meet credit quality standards, as specified in our corporate investment policy guidelines. These guidelines also limit the amount of credit exposure to any one issue, issuer or type of instrument. Our cash equivalents and short-term investments carried ratings from the major credit rating agencies that were in accordance with our corporate investment policy. Our investment policy allows investments in the following: government and federal agency obligations, repurchase agreements (“Repos”), certificates of deposit and time deposits, corporate obligations, medium term notes and deposit notes, commercial paper including asset-backed commercial paper (“ABCP”), puttable bonds, general obligation and revenue bonds, money market funds, taxable commercial paper, corporate notes/bonds, municipal notes, municipal obligations and tax exempt commercial paper. All such instruments must carry minimum ratings of A1/P1/F1, MIG1/VMIG1/SP1 and A2/A/A, as applicable, all of which are considered “investment grade”. Our investment policy for marketable securities requires that all securities mature in five years or less, with a weighted average maturity of no longer than 24 months with at least 10% maturing in 90 days or less. (See Note 2 – Cash, cash equivalents, short-term and long-term investments in Notes to Consolidated Financial Statements for further discussion and analysis of our investments). Concentration of credit risk with respect to trade accounts receivable is limited due to our large number of customers and their dispersion across many countries and industries. No single customer accounted for more than 3%, 3%, or 3% of sales for the years ended December 31, 2017, 2016, and 2015, respectively. The largest trade account receivable from any individual customer at December 31, 2017 was approximately $2.7 million. Key supplier risk Our manufacturing processes use large volumes of high-quality components and subassemblies supplied by outside sources. Several of these items are available through sole or limited sources. Supply shortages or quality problems in connection with these key items could require us to procure items from replacement suppliers, which would cause significant delays in fulfillment of orders and likely result in additional costs. In order to manage this risk, we maintain safety stock of some of these single sourced components and subassemblies and perform regular assessments of suppliers performance, grading key suppliers in critical areas such as quality and “on-time” delivery. Revenue recognition We sell test and measurement solutions that include hardware, software licenses, and related services. Our sales are generally made under standard sales arrangements with payment terms ranging from net 30 days in the U.S. to net 30 days and up to net 180 days in some international markets. We offer rights of return and standard warranties for product defects related to our products. The rights of return are generally for a period of up to 30 days after the delivery date. Our standard warranties cover periods ranging from 90 days to three years. Our standard sales arrangements do not require product acceptance from the customer. In recent years, we have made a concentrated effort to increase our revenue through the pursuit of orders with a value greater than $1.0 million. These orders often include contract terms that vary substantially from our standard terms of sale including product acceptance requirements and product performance evaluations which create uncertainty with respect to the timing of our ability to recognize revenue from such orders. These orders may also include most-favored customer pricing, significant discounts, extended payment terms and volume rebates, all of which may create uncertainty with respect to the amount and timing of revenue recognized from such orders. Sales of application software licenses include post-contract support services. Other services include customer training, customer support, and extended warranties. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable, and collectability is reasonably assured. Delivery is considered to have occurred when title and risk of loss have transferred to the customer. For most of our hardware and software sales, title and risk of loss transfer upon shipment. For services, we recognize revenue when the service is provided, except for extended warranties for which revenue is recognized ratably over the warranty period. We apply the separation guidance under U.S. GAAP for contracts with multiple deliverables. We analyze revenue arrangements with multiple deliverables to determine whether the deliverables should be divided into more than one unit of accounting. For contracts with more than one unit of accounting, we allocate the consideration we receive among the separate units of accounting based on their relative selling prices, which we determine based on prices of the deliverables as sold on a stand-alone basis, or if not sold on a stand-alone basis, the prices we would charge if sold on a stand-alone basis. We recognize revenue for each deliverable based on the revenue recognition policies described below. For software arrangements that include multiple elements, including perpetual software licenses and undelivered items (e.g., software maintenance; subscriptions/term licenses), we allocate and defer revenue for the undelivered items based on vendor specific objective evidence (“VSOE”) of the fair value of the undelivered elements, and recognize revenue on the perpetual license using the residual method. We base VSOE of each element on the price for which the undelivered element is sold separately. We determine fair value of the undelivered elements based on historical evidence of our stand-alone sales of these elements to third parties or from the stated renewal rate for the undelivered elements. When VSOE does not exist for undelivered items, we recognize the entire arrangement fee ratably over the applicable performance period. A portion of our revenues are generated from the sale of systems that contain software components that operate together with our hardware platform to provide the essential functionality of the system. When sold in a multiple element arrangement, these systems are considered non-software deliverables, so we can allocate the arrangement fee based upon relative selling price of each element. When applying the relative selling price method, we determine the selling price of each element using best estimate of selling price (“BESP”), because VSOE and third-party evidence (“TPE”) are not available. The revenues allocated to the software-related elements are recognized based on software industry specific revenue recognition guidance, as noted above. The revenues allocated to the non-software related elements are recognized based on the nature of the element provided. We estimate BESP by considering internal factors such as historical pricing practices and gross margin objectives, as well as market conditions such as competitor pricing strategies, customer demands and geography, and regularly review these assumptions. The application of revenue recognition standards requires judgment, including whether a software arrangement includes multiple elements, and if so, whether VSOE of fair value exists for those elements. Changes to the elements in a software arrangement, the ability to identify VSOE for those elements, the fair value of the respective elements, and changes to a product’s estimated life cycle could materially impact the amount of our earned and unearned revenue. Judgment is also required to assess whether future releases of certain software represent new products or upgrades and enhancements to existing products. Product revenue Our product revenue is generated predominantly from the sales of measurement and automation products. Our products consist of application software and hardware components together with related driver software. Software maintenance revenue Software maintenance revenue is post contract customer support that provides the customer with unspecified upgrades/updates and technical support. Shipping and handling costs Our shipping and handling costs charged to customers are included in net sales, and the associated expense is recorded in cost of sales. Warranty reserve We offer a one-year limited warranty on most hardware products which is included in the terms of sale of such products. We also offer optional extended warranties on our hardware products for which the related revenue is recognized ratably over the warranty period. Provision is made for estimated future warranty costs at the time of the sale for the estimated costs that may be incurred under the limited warranty. Our estimate is based on historical experience and product sales during the period. The warranty reserve for the years ended December 31, 2017, 2016, and 2015 was as follows:
Loss contingencies We accrue for probable losses from contingencies including legal defense costs, on an undiscounted basis, when such costs are considered probable of being incurred and are reasonably estimable. We periodically evaluate available information, both internal and external, relative to such contingencies and adjust this accrual as necessary. Advertising expense We expense costs of advertising as incurred. Advertising expense for the years ended December 31, 2017, 2016, and 2015 was $11 million, $12 million, and $12 million, respectively. Foreign currency translation The functional currency for our international sales operations is the applicable local currency. The assets and liabilities of these operations are translated at the rate of exchange in effect on the balance sheet date and sales and expenses are translated at average rates. The resulting gains or losses from translation are included in a separate component of other comprehensive income. Gains and losses resulting from re-measuring monetary asset and liability accounts that are denominated in a currency other than a subsidiary’s functional currency are included in net foreign exchange gain (loss) and are included in net income. Foreign currency hedging instruments All of our derivative instruments are recognized on the balance sheet at their fair value. We currently use foreign currency forward contracts to hedge our exposure to material foreign currency denominated receivables and forecasted foreign currency cash flows. On the date the derivative contract is entered into, we designate the derivative as a hedge of the variability of foreign currency cash flows to be received or paid (“cash flow” hedge) or as a hedge of our foreign denominated net receivable positions (“other derivatives”). Changes in the fair value of derivatives that are designated and qualify as cash flow hedges and that are deemed to be highly effective are recorded in other comprehensive income. These amounts are subsequently reclassified into earnings in the period during which the hedged transaction is realized. The gain or loss on the other derivatives as well as the offsetting gain or loss on the hedged item attributable to the hedged risk is recognized in current earnings under the line item “Net foreign exchange gain (loss)”. We do not enter into derivative contracts for speculative purposes. 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. We prospectively discontinue hedge accounting if (1) it is determined that the derivative is no longer highly effective in offsetting changes in the fair value of a hedged item (forecasted transactions); or (2) the derivative is de-designated as a hedge instrument, because it is unlikely that a forecasted transaction will occur. When hedge accounting is discontinued, the derivative is sold and the resulting gains and losses are recognized immediately in earnings. Income taxes We account for income taxes under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax basis of assets and liabilities and their reported amounts. Valuation allowances are established when necessary to reduce deferred tax assets to amounts which are more likely than not to be realized. Judgment is required in assessing the future tax consequences of events that have been recognized in our financial statements or tax returns. Variations in the actual outcome of these future tax consequences could materially impact our financial position or our results of operations. In estimating future tax consequences, all expected future events are considered other than enactments of changes in tax laws or rates. We account for uncertainty in income taxes recognized in our financial statements using prescribed recognition thresholds and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on our tax returns. Our continuing policy is to recognize interest and penalties related to income tax matters in income tax expense. Earnings per share Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing net income by the weighted average number of common shares and common share equivalents outstanding (if dilutive) during each period. The number of common share equivalents, which include stock options and restricted stock units (“RSUs”), is computed using the treasury stock method. The reconciliation of the denominators used to calculate basic EPS and diluted EPS for years ended December 31, 2017, 2016, and 2015 are as follows:
Stock awards to acquire 32,400 shares, 10,900 shares, and 292,400 shares for the years ended December 31, 2017, 2016, and 2015, respectively, were excluded in the computations of diluted EPS because the effect of including the stock awards would have been anti-dilutive. Stock-based compensation We account for stock-based compensation plans, which are more fully described in Note 11 – Authorized shares of common and preferred stock and stock-based compensation plans, using a fair-value method and recognize the expense in our Consolidated Statement of Income. Comprehensive income Our comprehensive income is comprised of net income, foreign currency translation and unrealized gains and losses on forward contracts and securities available-for-sale. Comprehensive income in 2017, 2016, and 2015 was $71 million, $86 million and $69 million, respectively. Recently Adopted Accounting Pronouncements In October 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-16, Income Taxes – Intra-Entity Transfers of Assets Other Than Inventory. The standard is intended to address diversity in practice and complexity in financial reporting, particularly for intra-entity transfers of intellectual property. We early adopted ASU 2016-16 effective January 1, 2017. Using the modified retrospective method, the impact of the adoption of the standard was to increase our deferred tax assets by $0.4 million, decrease other assets, net by $6.2 million and decrease retained earnings by $5.8 million. The adoption of the amendments had the effect of increasing our diluted earnings per share by $0.01 and $0.04 for the three and twelve months ended December 31, 2017, respectively. In March 2016, the FASB issued ASU 2016- 09, Improvements to Employee Share-Based Payment Accounting , which requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase a greater number of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. We adopted ASU 2016-09 effective January 1, 2017 as follows: •Our adoption of the amendments related to accounting for excess tax benefits resulted in the recognition of $3.2 million of excess tax benefits within income taxes rather than additional paid in capital for the twelve months ended December 31, 2017. •We elected to retrospectively apply the changes in presentation to the statements of cash flows and no longer classify excess tax benefits as a financing activity, which increased net cash provided by operating activities and reduced net cash provided by financing activities by an immaterial amount for the twelve months ended December 31, 2017. •We elected to account for forfeitures as they occur using a modified retrospective transition method. The adoption of this one-time accounting policy election did not have a material impact on our financial statements.In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory(Topic 330). The amendments require that reporting entities measure inventory at the lower of cost and 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 amendments apply to inventory that is measured using the first-in, first-out or average cost basis. We adopted ASU 2015-11 as of January 1, 2017 and the guidance was applied prospectively. We determined there were no changes to disclosure, financial statement presentation, or valuation of inventory as a result of adoption. Recently Issued Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The update is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. We adopted this standard as of January 1, 2018 by applying the modified retrospective transition method. We have reached conclusions on our key accounting matters related to the new standard and believe adoption of the new standard will generally result in revenue recognition earlier or at the same time as prior US GAAP. The most significant impact of the standard relates to our accounting for certain software arrangements. We primarily license software on a perpetual basis. However, we also license software under enterprise agreements which includes an unlimited quantity of certain software licenses for a fixed-term bundled with software maintenance, technical support, and a specified amount of training and service credits. Currently, we defer revenue for software licensed under our enterprise agreements and certain perpetual arrangements due to a lack of vendor specific objective evidence (“VSOE”) for certain elements in the contract. Under the new standard, we are no longer required to establish VSOE to recognize software license revenue separately from the other elements, and we will be able to recognize software license revenue once the customer obtains control of the license, which will generally occur at the start of each license term. Due to the complexity of our enterprise agreement contracts, the actual revenue recognition treatment required under the new standard will be dependent on contract-specific terms, and may vary in some instances from recognition at the time of billing. Additionally, we expect the new standard will impact the way we allocate the transaction price for arrangements with separately-priced extended warranty offerings. We adopted the new revenue recognition guidance effective January 1, 2018, by recognizing the cumulative effect of initially applying the new standard as an increase to the opening balance of retained earnings. We expect this adjustment to be less than $10 million, with an immaterial impact to our net income on an ongoing basis. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The ASU simplifies certain aspects of hedge accounting and improves disclosures of hedging arrangements through the elimination of the requirement to separately measure and report hedge ineffectiveness. The ASU generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item in order to align financial reporting of hedge relationships with economic results. Entities must apply the amendments to cash flow and net investment hedge relationships that exist on the date of adoption using a modified retrospective approach. The presentation and disclosure requirements must be applied prospectively. Our effective date for adoption of this guidance is our fiscal year beginning January 1, 2019. We are currently evaluating the effect that this guidance will have on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which supersedes ASC 840, Leases. The guidance requires lessees to recognize most lease liabilities on their balance sheets but recognize the expenses on their income statements in a manner similar to current practice. The update states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. The update is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. We are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures. Based on our initial assessment, we expect that the adoption of this standard will have a material impact on our balance sheet but that it will not have a material impact on our ongoing results of operations. We do not expect to adopt the new standard prior to the required effective date. |

| Fair value measurements | Fair value measurements We define fair value to be the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market that market participants may use when pricing the asset or liability. We follow a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. Fair value measurement is determined based on the lowest level input that is significant to the fair value measurement. The three values of the fair value hierarchy are the following: Level 1 – Quoted prices in active markets for identical assets or liabilities Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly Level 3 – Inputs that are not based on observable market data Assets and liabilities measured at fair value on a recurring basis are summarized below:
We value our available-for-sale short-term investments based on pricing from third party pricing vendors, who may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. We classify all of our fixed income available-for-sale securities as having Level 2 inputs. The valuation techniques used to measure the fair value of our financial instruments having Level 2 inputs were derived from non-binding market consensus prices that are corroborated by observable market data, quoted market prices for similar instruments, or pricing models, such as discounted cash flow techniques. We believe all of these sources reflect the credit risk associated with each of our available-for-sale short-term investments. Short-term investments available-for-sale consists of debt securities issued by states of the U.S. and political subdivisions of the U.S., corporate debt securities and debt securities issued by U.S. government organizations and agencies. All short-term investments available-for-sale have contractual maturities of less than 52 months. Derivatives include foreign currency forward and option contracts. Our foreign currency forward contracts are valued using an income approach (Level 2) based on the spot rate less the contract rate multiplied by the notional amount. Our foreign currency option contracts are valued using a market approach based on the quoted market prices which are derived from observable inputs including current and future spot rates, interest rate spreads as well as quoted market prices of similar instruments. We consider counterparty credit risk in the valuation of our derivatives. However, counterparty credit risk did not impact the valuation of our derivatives during the year ended December 31, 2017. There were not any transfers in or out of Level 1 or Level 2 during the year ended December 31, 2017. Our short-term investments do not include any foreign sovereign debt. The majority of our short-term investments that are located outside of the U.S. are denominated in the U.S. dollar with the exception of $5.0 million U.S. dollar equivalent of corporate bonds that are denominated in Euro. We did not have any items that were measured at fair value on a nonrecurring basis at December 31, 2017 and December 31, 2016. The carrying value of net accounts receivable, accounts payable, and long-term debt contained in the Consolidated Balance Sheets approximates fair value. |

| Derivative Instruments and Hedging Activities Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Derivative instruments and hedging activities | Derivative instruments and hedging activities We recognize all of our derivative instruments as either assets or liabilities in our statement of financial position at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, we designate the hedging instrument, based upon the exposure being hedged, as a fair value hedge, cash flow hedge, or a hedge of a net investment in a foreign operation. We have operations in over 50 countries. Sales outside of the Americas accounted for approximately 61%, 61%, and 59% of our revenues during the years ended December 31, 2017, 2016, and 2015, respectively. Our activities expose us to a variety of market risks, including the effects of changes in foreign currency exchange rates. These financial risks are monitored and managed by us as an integral part of our overall risk management program. We maintain a foreign currency risk management strategy that uses derivative instruments (foreign currency forward contracts) to help protect our earnings and cash flows from fluctuations caused by the volatility in currency exchange rates. Movements in foreign currency exchange rates pose a risk to our operations and competitive position, since exchange rate changes may affect our profitability and cash flow, and the business or pricing strategies of our non-U.S. based competitors. The vast majority of our foreign sales are denominated in the customers’ local currency. We purchase foreign currency forward contracts as hedges of forecasted sales that are denominated in foreign currencies and as hedges of foreign currency denominated receivables. These contracts are entered into to help protect against the risk that the eventual dollar-net-cash inflows resulting from such sales or firm commitments will be adversely affected by changes in exchange rates. We also purchase foreign currency forward contracts as hedges of forecasted expenses that are denominated in foreign currencies. These contracts are entered into to help protect against the risk that the eventual dollar-net-cash outflows resulting from foreign currency operating and cost of revenue expenses will be adversely affected by changes in exchange rates. We designate foreign currency forward contracts as cash flow hedges of forecasted revenues or forecasted expenses. In addition, we hedge our foreign currency denominated balance sheet exposures using foreign currency forward contracts that are not designated as hedging instruments. None of our derivative instruments contain a credit-risk-related contingent feature. Cash flow hedges To help protect against the reduction in value caused by a fluctuation in foreign currency exchange rates of forecasted foreign currency cash flows resulting from international sales over the next one to three years, we have instituted a foreign currency cash flow hedging program. We hedge portions of our forecasted revenue and forecasted expenses denominated in foreign currencies with forward contracts. For forward contracts, when the dollar strengthens significantly against the foreign currencies, the change in the present value of future foreign currency cash flows may be offset by the change in the fair value of the forward contracts designated as hedges. We purchase foreign currency forward for up to 100% of our forecasted exposures in selected currencies (primarily in Euro, Japanese yen, Malaysian ringgit, British pound, Chinese yuan, and Hungarian forint) and limit the duration of these contracts to 40 months or less. For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the gain or loss on the derivative is reported as a component of accumulated other comprehensive income (“OCI”) and reclassified into earnings in the same line item (net sales, operating expenses, or cost of sales) associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings or expenses during the current period and are classified as a component of “net foreign exchange gain (loss)”. Hedge effectiveness of foreign currency forwards designated as cash flow hedges are measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the forecasted transaction’s terminal value. We held forward contracts with the following notional amounts:
The contracts in the foregoing table had contractual maturities of 24 months or less and 36 months or less at December 31, 2017 and December 31, 2016, respectively. At December 31, 2017, we expect to reclassify $6.0 million of losses on derivative instruments from accumulated OCI to net sales during the next twelve months when the hedged international sales occur, $1.4 million of gains on derivative instruments from accumulated OCI to cost of sales when the cost of sales are incurred and $1.4 million of gains on derivative instruments from accumulated OCI to operating expenses during the next twelve months when the hedged operating expenses occur. Expected amounts are based on derivative valuations at December 31, 2017. Actual results may vary as a result of changes in the corresponding exchange rates subsequent to this date. The gains and losses recognized in earnings due to hedge ineffectiveness were not material for fiscal years 2017, 2016, and 2015 and are included as a component of net income. Other Derivatives Other derivatives not designated as hedging instruments consist primarily of foreign currency forward contracts that we use to hedge our foreign denominated net receivable or net payable positions to protect against the change in value caused by a fluctuation in foreign currency exchange rates. We typically attempt to hedge up to 90% of our outstanding foreign denominated net receivables or net payables and typically limit the duration of these foreign currency forward contracts to approximately 120 days. The gain or loss on the derivatives as well as the offsetting gain or loss on the hedge item attributable to the hedged risk is recognized in current earnings under the line item “net foreign exchange gain (loss).” As of December 31, 2017 and December 31, 2016, we held foreign currency forward contracts with a notional amount of $63 million and $60 million, respectively. The following tables present the fair value of derivative instruments on our Consolidated Balance Sheets and the effect of derivative instruments on our Consolidated Statements of Income.

The following tables present the effect of derivative instruments on our Consolidated Statements of Income for the years ended December 31, 2017 and 2016, respectively:
