Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies The accompanying consolidated financial statements reflect the application of the significant accounting policies described below. Nature of Operations Cognex Corporation is a leading provider of machine vision products that capture and analyze visual information in order to automate tasks, primarily in manufacturing processes, where vision is required. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities as of the balance sheet date, and the reported amounts of revenues and expenses during the year. Actual results could differ from those estimates. Significant estimates and judgments include those related to revenue recognition, investments, accounts receivable, inventories, long-lived assets, goodwill, warranty obligations, contingencies, stock-based compensation, income taxes and derivative instruments. Basis of Consolidation The consolidated financial statements include the accounts of Cognex Corporation and its subsidiaries, all of which are wholly-owned. All intercompany accounts and transactions have been eliminated. Foreign Currency Translation The financial statements of the Company’s foreign subsidiaries, where the local currency is the functional currency, are translated using exchange rates in effect at the end of the year for assets and liabilities and average exchange rates during the year for results of operations. The resulting foreign currency translation adjustment, net of tax, is recorded in shareholders’ equity as other comprehensive income (loss). Fair Value Measurements The Company applies a three-level valuation hierarchy for fair value measurements. The categorization of assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the measurement of fair value. Level 1 inputs to the valuation methodology utilize unadjusted quoted market prices in active markets for identical assets and liabilities. Level 2 inputs to the valuation methodology are other observable inputs, including quoted market prices for similar assets and liabilities, quoted prices for identical and similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 inputs to the valuation methodology are unobservable inputs based upon management’s best estimate of the inputs that market participants would use in pricing the asset or liability at the measurement date, including assumptions about risk. A change to the level of an asset or liability within the fair value hierarchy is determined at the end of a reporting period. Cash, Cash Equivalents, and Investments Money market instruments purchased with original maturities of three months or less are classified as cash equivalents and are stated at amortized cost. Debt securities with original maturities greater than three months and remaining maturities of one year or less are classified as short-term investments, as well as equity securities that the Company intends to sell within one year. Debt securities with remaining maturities greater than one year, as well as a limited partnership interest, are classified as long-term investments. It is the Company’s policy to invest in debt securities with effective maturities that do not exceed ten years. Debt securities with original maturities greater than three months are designated as available-for-sale and are reported at fair value, with unrealized gains and losses, net of tax, recorded in shareholders’ equity as other comprehensive income (loss). Equity securities that are held for short periods of time with the intention of selling them in the near term are designated as trading and are reported at fair value, with unrealized gains and losses recorded in current operations. Realized gains and losses are included in current operations, along with the amortization of the discount or premium on debt securities arising at acquisition, and are calculated using the specific identification method. The Company’s limited partnership interest is accounted for using the cost method because the Company’s investment is less than 5% of the partnership and the Company has no influence over the partnership’s operating and financial policies. Management monitors the carrying value of its investments in debt securities and a limited partnership interest compared to their fair value to determine whether an other-than-temporary impairment has occurred. If the fair value of a debt security is less than its amortized cost, the Company assesses whether the impairment is other-than-temporary. In considering whether a decline in fair value is other-than-temporary, we consider many factors. In its evaluation of its debt securities, management considers the type of security, the credit rating of the security, the length of time the security has been in a loss position, the size of the loss position, our intent and ability to hold the security to expected recovery of value, and other meaningful information. An impairment is considered other-than-temporary if (i) the Company has the intent to sell the security, (ii) it is more likely than not that the Company will be required to sell the security before recovery of the entire amortized cost basis, or (iii) the Company does not expect to recover the entire amortized cost basis of the security. If impairment is considered other-than-temporary based upon condition (i) or (ii) described above, the entire difference between the amortized cost and the fair value of the security is recognized in current operations. If an impairment is considered other-than-temporary based upon condition (iii), the amount representing credit losses (defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis of the security) is recognized in current operations and the amount relating to all other factors is recognized in shareholders' equity as other comprehensive income (loss). In its evaluation of its limited partnership interest, management considers the duration and extent of the decline, the length of the Company’s commitment to the investment, general economic trends, and specific communications with the General Partner. Accounts Receivable The Company extends credit with various payment terms to customers based upon an evaluation of their financial condition. Accounts that are outstanding longer than the payment terms are considered to be past due. The Company establishes reserves against accounts receivable for potential credit losses and records bad debt expense in current operations when it determines receivables are at risk for collection based upon the length of time the receivable has been outstanding, the customer’s current ability to pay its obligations to the Company, general economic and industry conditions, as well as various other factors. Receivables are written off against these reserves in the period they are determined to be uncollectible and payments subsequently received on previously written-off receivables are recorded as a reversal of the bad debt expense. Inventories Inventories are stated at the lower of cost or market. Cost is determined using standard costs, which approximates actual costs under the first-in, first-out (FIFO) method. The Company’s inventory is subject to rapid technological change or obsolescence. The Company reviews inventory quantities on hand and estimates excess and obsolescence exposures based upon assumptions about future demand, product transitions, and market conditions, and records reserves to reduce the carrying value of inventories to their net realizable value. If actual future demand is less than estimated, additional inventory write-downs would be required. The Company generally disposes of obsolete inventory upon determination of obsolescence. The Company does not dispose of excess inventory immediately, due to the possibility that some of this inventory could be sold to customers as a result of differences between actual and forecasted demand. When inventory has been written down below cost, such reduced amount is considered the new cost basis for subsequent accounting purposes. As a result, the Company would recognize a higher than normal gross margin if the reserved inventory were subsequently sold. Property, Plant, and Equipment Property, plant, and equipment are stated at cost and depreciated using the straight-line method over the assets’ estimated useful lives. Buildings’ useful lives are 39 years, building improvements’ useful lives are ten years, and the useful lives of computer hardware and software, manufacturing test equipment, and furniture and fixtures range from two to five years. Leasehold improvements are depreciated over the shorter of the estimated useful lives or the remaining terms of the leases. Maintenance and repairs are expensed when incurred; additions and improvements are capitalized. Upon retirement or disposition, the cost and related accumulated depreciation of the disposed assets are removed from the accounts, with any resulting gain or loss included in current operations. Goodwill Goodwill is stated at cost. The Company evaluates the possible impairment of goodwill annually each fourth quarter and whenever events or circumstances indicate the carrying value of the goodwill may not be recoverable. For the past five years, the Company has performed a qualitative assessment of goodwill (commonly known as “step zero”) to determine whether further impairment testing is necessary. Factors that management considers in this assessment include macroeconomic conditions, industry and market considerations, overall financial performance (both current and projected), changes in management or strategy, and changes in the composition or carrying amount of net assets. In addition, management takes into consideration the goodwill valuation under the last quantitative analysis that was performed. If this qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the entity would proceed to a two-step process. Step one compares the fair value of the reporting unit with its carrying value, including goodwill. If the carrying amount exceeds the fair value of the reporting unit, step two is required to measure the amount of impairment loss. Step two compares the implied fair value of the reporting unit goodwill to the carrying amount of the goodwill. Intangible Assets Intangible assets are stated at cost and amortized over the assets’ estimated useful lives. Intangible assets are either amortized in relation to the relative cash flows anticipated from the intangible asset or using the straight-line method, depending upon facts and circumstances. The useful lives of distribution networks range from eleven to twelve years, of customer contracts and relationships from five to twelve years, and of completed technologies and other intangible assets from three to eight years. The Company evaluates the possible impairment of long-lived assets, including intangible assets, whenever events or circumstances indicate the carrying value of the assets may not be recoverable. At the occurrence of a certain event or change in circumstances, the Company evaluates the potential impairment of an asset by estimating the future undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the sum of the estimated future cash flows is less than the carrying value, the Company determines the amount of such impairment by comparing the fair value of the asset to its carrying value. The fair value is based upon the present value of the estimated future cash flows using a discount rate commensurate with the risks involved. Warranty Obligations The Company warrants its products to be free from defects in material and workmanship for periods primarily ranging from one to three years from the time of sale based upon the product being purchased and the terms of the customer arrangement. Warranty obligations are evaluated and recorded at the time of sale since it is probable that customers will make claims under warranties related to products that have been sold and the amount of these claims can be reasonably estimated based upon historical costs to fulfill claims. Obligations may also be recorded subsequent to the time of sale whenever specific events or circumstances impacting product quality become known that would not have been taken into account using historical data. Contingencies Loss contingencies are accrued if the loss is probable and the amount of the loss can be reasonably estimated. Legal costs associated with potential loss contingencies, such as patent infringement matters, are expensed as incurred. Revenue Recognition The Company’s product revenue is derived from the sale of machine vision systems, which can take the form of hardware with embedded software or software-only, and related accessories. The Company also generates revenue by providing maintenance and support, consulting, and training services to its customers. Certain of the Company’s arrangements include multiple deliverables that provide the customer with a combination of products or services. In order to recognize revenue, the Company requires that a signed customer contract or purchase order is received, the fee from the arrangement is fixed or determinable, and collection of the resulting receivable is probable. Assuming that these criteria have been met, product revenue is generally recognized upon delivery, revenue from maintenance and support programs is recognized ratably over the program period, and revenue from consulting and training services is recognized when the services have been provided. When customer-specified acceptance criteria exists that are substantive, product revenue is deferred until these criteria have been met, along with the associated incremental direct costs. The majority of the Company’s product offerings consist of hardware with embedded software. Under the revenue recognition rules for tangible products, the fee from a multiple-deliverable arrangement is allocated to each of the deliverables based upon their relative selling prices as determined by a selling-price hierarchy. A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a stand-alone basis. A delivered item that does not qualify as a separate unit of accounting is combined with the other undelivered items in the arrangement and revenue is recognized for those combined deliverables as a single unit of accounting. The selling price used for each deliverable is based upon vendor-specific objective evidence (VSOE) if available, third-party evidence (TPE) if VSOE is not available, and management’s best estimate of selling price (BESP) if neither VSOE nor TPE are available. VSOE is the price charged for a deliverable when it is sold separately. TPE is the price of the Company’s or any competitor’s largely interchangeable products or services in stand-alone sales to similarly-situated customers. BESP is the price at which the Company would sell the deliverable if it were sold regularly on a stand-alone basis, considering market conditions and entity-specific factors. The selling prices used in the relative selling price allocation method for (1) certain of the Company’s services are based upon VSOE, (2) third-party accessories available from other vendors are based upon TPE, and (3) hardware products with embedded software, custom accessories, and services for which VSOE does not exist are based upon BESP. The Company does not believe TPE exists for these products and services because they are differentiated from competing products and services in terms of functionality and performance and there are no competing products or services that are largely interchangeable. BESP has been established for each product line within each region. Management establishes BESP with consideration for market conditions, such as the impact of competition and geographic considerations, and entity-specific factors, such as pricing practices, gross margin objectives, customer size, and market share goals. Management believes that BESP is reflective of reasonable pricing of that deliverable as if priced on a stand-alone basis. Under the revenue recognition rules for software-only products, the fee from a multiple-deliverable arrangement is allocated to each of the undelivered elements based upon VSOE, which is limited to the price charged when the same deliverable is sold separately, with the residual value from the arrangement allocated to the delivered element. The portion of the fee that is allocated to each deliverable is then recognized as revenue when the criteria for revenue recognition are met with respect to that deliverable. If VSOE does not exist for all of the undelivered elements, then all revenue from the arrangement is typically deferred until all elements have been delivered to the customer. The Company’s products are sold directly to end users, as well as to resellers including original equipment manufacturers (OEMs), distributors, and integrators. Revenue is recognized upon delivery of the product to the reseller, assuming all other revenue recognition criteria have been met. The Company establishes reserves against revenue for potential product returns, since the amount of future returns can be reasonably estimated based upon experience. These reserves have historically been immaterial. Amounts billed to customers related to shipping and handling, as well as reimbursements received from customers for out-of-pocket expenses, are classified as revenue, with the associated costs included in cost of revenue. Research and Development Research and development costs for internally-developed or acquired products are expensed when incurred until technological feasibility has been established for the product. Thereafter, all software costs may be capitalized until the product is available for general release to customers. The Company determines technological feasibility at the time the product reaches beta in its stage of development. Historically, the time incurred between beta and general release to customers has been short, and therefore, the costs have been insignificant. Advertising Costs Advertising costs are expensed as incurred and totaled $2,009,000 in 2015 , $2,609,000 in 2014 , and $2,219,000 in 2013 . Stock-Based Compensation The Company’s share-based payments that result in compensation expense consist of stock option grants and restricted stock awards. The Company has reserved a specific number of shares of its authorized but unissued shares for issuance upon the exercise of stock options or the granting of restricted stock. When a stock option is exercised or a restricted stock award is granted, the Company issues new shares from this pool. The fair values of stock options are estimated on the grant date using a binomial lattice model. Management is responsible for determining the appropriate valuation model and estimating these fair values, and in doing so, considers a number of factors, including information provided by an outside valuation advisor. The Company recognizes compensation expense related to stock options using the graded attribution method, in which expense is recognized on a straight-line basis over the service period for each separately vesting portion of the stock option as if the option was, in substance, multiple awards. The amount of compensation expense recognized at the end of the vesting period is based upon the number of stock options for which the requisite service has been completed. No compensation expense is recognized for options that are forfeited for which the employee does not render the requisite service. The term “forfeitures” is distinct from “expirations” and represents only the unvested portion of the surrendered option. The Company applies estimated forfeiture rates to its unvested options to arrive at the amount of compensation expense that is expected to be recognized over the requisite service period. At the end of each separately vesting portion of an option, the expense that was recognized by applying the estimated forfeiture rate is compared to the expense that should be recognized based upon the employee’s service, and a credit to expense is recorded related to those employees that have not rendered the requisite service. Taxes The Company recognizes a tax position in its financial statements when that tax position, based solely upon its technical merits, is more likely than not to be sustained upon examination by the relevant taxing authority. Those tax positions failing to qualify for initial recognition are recognized in the first interim period in which they meet the more likely than not standard, or are resolved through negotiation or litigation with the taxing authority, or upon expiration of the statutes of limitations. Derecognition of a tax position that was previously recognized occurs when an entity subsequently determines that a tax position no longer meets the more likely than not threshold of being sustained. Only the portion of the liability that is expected to be paid within one year is classified as a current liability. As a result, liabilities expected to be resolved without the payment of cash (e.g., resolution due to the expiration of the statutes of limitations) or are not expected to be paid within one year are not classified as current. It is the Company’s policy to record estimated interest and penalties as income tax expense and tax credits as a reduction in income tax expense. Deferred tax assets and liabilities are determined based upon the differences between the financial statement and tax bases of assets and liabilities as measured by the enacted tax rates that will be in effect when these differences reverse. Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Sales tax in the United States and similar taxes in other jurisdictions that are collected from customers and remitted to government authorities are presented on a gross basis (i.e., a receivable from the customer with a corresponding payable to the government). Amounts collected from customers and retained by the Company during tax holidays are recognized as non-operating income when earned. Net Income Per Share Basic net income per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted net income per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period plus potential dilutive common shares. Dilutive common equivalent shares consist of stock options and are calculated using the treasury stock method. Common equivalent shares do not qualify as participating securities. In periods where the Company records a net loss, potential common stock equivalents are not included in the calculation of diluted net loss per share. Comprehensive Income Comprehensive income is defined as the change in equity of a company during a period from transactions and other events and circumstances, excluding transactions resulting from investments by owners and distributions to owners. Accumulated other comprehensive loss, net of tax, as of December 31, 2015 and December 31, 2014 , consists of foreign currency translation adjustments of $49,646,000 and $38,030,000 , respectively; net unrealized losses on available-for-sale investments of $1,413,000 and $130,000 , respectively; net unrealized gains on derivative instruments of $ 206,000 and $ 32,000 , respectively; and losses on currency swaps, net of gains on long-term intercompany loans, of $1,271,000 and $ 1,271,000 , respectively. Amounts reclassified from accumulated other comprehensive income to investment income on the Consolidated Statements of Operations were net realized gains of $344,000 , $673,000 , and $314,000 for 2015 , 2014 , and 2013 , respectively. Concentrations of Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, investments, and trade receivables. The Company has certain domestic and foreign cash balances that exceed the insured limits set by the Federal Deposit Insurance Corporation (FDIC) in the United States and equivalent regulatory agencies in foreign countries. The Company primarily invests in investment-grade debt securities and has established guidelines relative to credit ratings, diversification, and maturities of its debt securities that maintain safety and liquidity. The Company has not experienced any significant realized losses on its debt securities. The Company performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. The Company has not experienced any significant losses related to the collection of its accounts receivable. A significant portion of the Company's product is manufactured by a third-party contractor located in Indonesia. This contractor has agreed to provide Cognex with termination notification periods and last-time-buy rights, if and when that may be applicable. We rely upon this contractor to provide quality product and meet delivery schedules. We engage in extensive product quality programs and processes, including actively monitoring the performance of our third-party manufacturers; however, we may not detect all product quality issues through these programs and processes. Certain components are presently sourced from a single vendor that is selected based on price and performance considerations. In the event of a supply disruption from a single-source vendor, these components may be purchased from an alternative vendor, which may result in manufacturing delays based on the lead time of the new vendor. Certain key electronic and mechanical components that are purchased from strategic suppliers, such as processors or imagers, are fundamental to the design of Cognex products. A disruption in the supply of these key components, such as a last-time-buy announcement, natural disaster, financial bankruptcy, or other event, may require us to purchase a significant amount of inventory at unfavorable prices resulting in lower gross margins and higher risk of carrying excess inventory. If we are unable to secure adequate supply from alternative sources, we may have to redesign our products, which may lead to a delay in manufacturing and a possible loss of sales. Derivative Instruments Derivative instruments are recorded on the Consolidated Balance Sheets at fair value. Changes in the fair value of derivatives are recorded each period in current operations or in shareholders' equity as other comprehensive income (loss), depending upon whether the derivative is designated as a hedge transaction and, if it is, the effectiveness of the hedge. At the inception of the contract, the Company designates foreign currency forward exchange contracts as either a cash flow hedge of certain forecasted foreign currency denominated sales and purchase transactions or as an economic hedge. Changes in the fair value of a derivative that is highly effective and that is designated and qualifies as a cash flow hedge are recorded in shareholders' equity as other comprehensive income (loss), and reclassified into current operations in the same period during which the hedged transaction affects current operations and in the same financial statement line item as that of the forecasted transaction. Cash flow hedges are evaluated for effectiveness quarterly. Any hedge ineffectiveness (which represents the amount by which the changes in the fair value of the derivative exceed the variability in the cash flows of the forecasted transaction) is recorded in current operations in the period in which ineffectiveness is determined. Changes in the fair value of the Company’s economic hedges (not designated as a cash flow hedge) are reported in current operations. The cash flows from derivative instruments are presented in the same category on the Consolidated Statements of Cash Flows as the category for the cash flows from the hedged item. Generally, this accounting policy election results in cash flows related to derivative instruments being classified as an operating activity on the Consolidated Statements of Cash Flows. The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to specific forecasted transactions. The Company also formally assesses (both at the hedge’s inception and on an ongoing basis) whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the fair value or cash flows of hedged items and whether those derivatives may be expected to remain highly effective in future periods. When it is determined that a derivative is not (or has ceased to be) highly effective as a hedge, the Company discontinues hedge accounting prospectively, as discussed below. The Company discontinues hedge accounting prospectively when (1) it determines that the derivative is no longer effective in offsetting changes in the cash flows of a hedged item; (2) the derivative expires or is sold, terminated, or exercised; (3) it is no longer probable that the forecasted transaction will occur; or (4) management determines that designating the derivative as a hedging instrument is no longer appropriate or desired. When the Company discontinues hedge accounting because it is no longer probable that the forecasted transaction will occur in the originally expected period, the gain or loss on the derivative remains in accumulated other comprehensive income (loss) and is reclassified into current operations when the forecasted transaction affects current operations. However, if it is probable that a forecasted transaction will not occur by the end of the originally specified time period or within an additional two-month period of time thereafter, the gain or loss that was accumulated in other comprehensive income (loss) is recognized immediately in current operations. In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company carries the derivative at fair value on the Consolidated Balance Sheets, recognizing changes in the fair value in current operations, unless it is designated in a new hedging relationship. The Company recognizes all derivative instruments as either current assets or current liabilities at fair value on the Consolidated Balance Sheets. When the Company is engaged in more than one outstanding derivative contract with the same counterparty and also has a legally enforceable master netting agreement with that counterparty, the “net” mark-to-market exposure represents the netting of the positive and negative exposures with that counterparty. Accordingly, cash flow hedges are presented net on the Consolidated Balance Sheets. |

Accounting Changes and Error Corrections [Abstract] | |
New Pronouncements | New Pronouncements Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers” The amendments in ASU 2014-09 will supersede and replace all currently existing U.S. GAAP, including industry-specific revenue recognition guidance, with a single, principle-based revenue recognition framework. The concept guiding this new model is that revenue recognition will depict transfer of control to the customer in an amount that reflects consideration to which an entity expects to be entitled. The core principles supporting this framework include (1) identifying the contract with a customer, (2) identifying separate performance obligations within the contract, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations, and (5) recognizing revenue. This new framework will require entities to apply significantly more judgment. This increase in management judgment will require expanded disclosure on estimation methods, inputs, and assumptions for revenue recognition. The Transition Resource Group (TRG) is evaluating the impact of this ASU and will release implementation guidance in future periods. ASU 2015-14, "Deferral of the effective date" amended the effective date of ASU 2014-09 for public companies to annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but only beginning after December 15, 2016. Management will continue to evaluate the impact of this standard as it evolves. Accounting Standards Update (ASU) 2015-05, "Customer's Accounting for Fees Paid in a Cloud Computing Arrangement" ASU 2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, then the customer should account for the arrangement as a service contract. For public companies, the guidance in ASU 2015-05 is effective for annual periods beginning after December 15, 2015, and interim periods within those annual periods. Early adoption is permitted. Management does not expect ASU 2015-05 to have a material impact on the Company's financial statements and disclosures. Accounting Standards Update (ASU) 2015-11, "Inventory - Simplifying the Measurement of Inventory" ASU 2015-11 requires companies to measure most inventory at the lower of cost and net realizable value, thereby simplifying the current guidance under which a company must measure inventory at the lower of cost or market. This ASU eliminates the need to determine replacement cost and evaluate whether said cost is within a quantitative range. This ASU also further aligns U.S. GAAP and international accounting standards. For public companies, the guidance in ASU 2015-11 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. Management does not expect ASU 2015-11 to have a material impact on the Company's financial statements and disclosures. Accounting Standards Update (ASU) 2015-16, "Business Combinations - Simplifying the Accounting for Measurement-Period Adjustments" ASU 2015-16 simplifies the requirements to retrospectively account for adjustments made to provisional amounts recognized in a business combination. This ASU applies to all entities that have reported provisional amounts for items in a business combination for which the accounting is incomplete by the end of the reporting period in which the combination occurs and that have recognized an adjustment to provisional amounts during the measurement period. For public companies, the guidance in ASU 2015-16 is effective for annual periods beginning after December 15, 2015, and interim periods within those annual periods. This ASU should be applied prospectively to adjustments to provisional amounts that occur after the effective date. Management does not expect ASU 2015-16 to have a material impact on the Company's financial statements and disclosures. Accounting Standard Update (ASU) 2015-17, "Income Taxes - Balance Sheet Classification of Deferred Taxes” ASU 2015-17 simplifies the presentation of deferred income taxes to require that deferred tax assets and liabilities be classified as non-current in a classified balance sheet. Current U.S. GAAP requires an entity to separate deferred income tax assets and liabilities into current and non-current amounts in a classified balance sheet. The current requirement that deferred tax assets and liabilities of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments of this Update. For public companies, the guidance in ASC 2015-17 is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier adoption is permitted. Management will comply with the presentation and disclosure requirements of ASU-2017 for the year ended December 31, 2016. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Fair Value Measurements Financial Assets and Liabilities that are Measured at Fair Value on a Recurring Basis The following table summarizes the financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2015 (in thousands): Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Unobservable Inputs (Level 3) Assets: Money market instruments $ 6,024 $ — $ — Corporate bonds — 230,951 — Treasury bills — 153,797 — Asset-backed securities — 86,576 — Euro liquidity fund — 47,730 — Sovereign bonds — 34,943 — Agency bonds — 9,158 — Municipal bonds — 5,459 — Cash flow hedge forward contracts — 441 — Economic hedge forward contracts — 9 — Liabilities: Cash flow hedge forward contracts — (201 ) — Economic hedge forward contracts — (43 ) — Contingent consideration liability (Note 20) — — (3,000 ) The Company’s money market instruments are reported at fair value based upon the daily market price for identical assets in active markets, and are therefore classified as Level 1. The Company’s debt securities and forward contracts are reported at fair value based upon model-driven valuations in which all significant inputs are observable or can be derived from or corroborated by observable market data for substantially the full term of the asset or liability, and are therefore classified as Level 2. Management is responsible for estimating the fair value of these financial assets and liabilities, and in doing so, considers valuations provided by a large, third-party pricing service. For debt securities, this service maintains regular contact with market makers, brokers, dealers, and analysts to gather information on market movement, direction, trends, and other specific data. They use this information to structure yield curves for various types of debt securities and arrive at the daily valuations. The Company's forward contracts are typically traded or executed in over-the-counter markets with a high degree of pricing transparency. The market participants are generally large commercial banks. The Company's contingent consideration liability is reported at fair value based upon probability-adjusted present values of the consideration expected to be transferred using significant inputs that are not observable in the market, and are therefore classified as Level 3. Key assumptions used in these estimates include probability assessments with respect to the likelihood of achieving the revenue milestones and discount rates consistent with the level of risk of achievement. The Company did not record an other-than-temporary impairment of these financial assets in 2015 , 2014 , or 2013 . Financial Assets that are Measured at Fair Value on a Non-recurring Basis The Company has an interest in a limited partnership, which is accounted for using the cost method and is required to be measured at fair value on a non-recurring basis. Management is responsible for estimating the fair value of this investment, and in doing so, considers valuations of the partnership’s investments as determined by the General Partner. Publicly-traded investments in active markets are reported at the market closing price less a discount, as appropriate, to reflect restricted marketability. Fair value for private investments for which observable market prices in active markets do not exist is based upon the best information available including the value of a recent financing, reference to observable valuation measures for comparable companies (such as revenue multiples), public or private transactions (such as the sale of a comparable company), and valuations for publicly-traded comparable companies. The valuations also incorporate the General Partner’s own judgment and close familiarity with the business activities of each portfolio company. Significant increases or decreases in any of these inputs in isolation may result in a significantly lower or higher fair value measurement. The portfolio consists of securities of public and private companies, and consequently, inputs used in the fair value calculation are classified as Level 3. The Company did not record an other-than-temporary impairment of this investment in 2015 , 2014 , or 2013 . Non-financial Assets that are Measured at Fair Value on a Non-recurring Basis Non-financial assets such as property, plant, and equipment, goodwill, and intangible assets are required to be measured at fair value only when an impairment loss is recognized. The Company did not record an impairment charge related to these assets in 2015 , 2014 , or 2013 . |

In its evaluation, management considered the type of security, the credit rating of the security, the length of time the security has been in a loss position, the size of the loss position, our intent and ability to hold the security to expected recovery of value, and other meaningful information. The Company does not intend to sell, and is unlikely to be required to sell, any of these available-for-sale investments before its effective maturity or market price recovery. The Company recorded gross realized gains on the sale of debt securities totaling $549,000 in 2015 , $843,000 in 2014 , and $508,000 in 2013, and gross realized losses on the sale of debt securities totaling $205,000 in 2015 , $170,000 in 2014 , and $194,000 in 2013. These gains and losses are included in "Investment income" on the Consolidated Statement of Operations. Prior to the sale of these securities, unrealized gains and losses for these debt securities, net of tax, are recorded in shareholders’ equity as other comprehensive income (loss).

Goodwill assigned to SISD was $4,301,000 and has been included as part of the sale. The Company had previously identified SISD, along with its Modular Vision Systems Division (MVSD), as reporting units for purposes of its goodwill impairment test. Given the disposition of SISD, management reviewed its reporting units and concluded that the Company now has one reporting unit . For its 2015 analysis of goodwill, management elected to perform a qualitative assessment (commonly known as “step zero”). Based upon this assessment, management does not believe that it is more likely than not that the carrying value of the reporting unit exceeds its fair value. Factors that management considered in the qualitative assessment include macroeconomic conditions, industry and market considerations, overall financial performance (both current and projected), changes in management or strategy, and changes in the composition or carrying amount of net assets. In addition, management took into consideration the goodwill valuation as of October 4, 2010, which was the last time it was performed under the two-step process. At that time, this analysis indicated that the fair value of the MVSD reporting unit exceeded its carrying value by approximately 208% . As of December 31, 2015 , management does not believe any qualitative factors exist that would change the conclusion of their assessment. |

Certain of these purchase orders may be canceled by the Company, subject to cancellation penalties. These purchase commitments relate to expected sales in 2016. The Company conducts certain of its operations in leased facilities. These lease agreements expire at various dates through 2023 and are accounted for as operating leases. Certain of these leases contain renewal options, retirement obligations, escalation clauses, rent holidays, and leasehold improvement incentives. Annual rental expense totaled $5,778,000 in 2015 , $5,560,000 in 2014 , and $5,378,000 in 2013 .

(“Microscan”) and Code Corporation ("Code") in the United States District Court for the Southern District of New York alleging that Microscan’s Mobile Hawk handheld imager infringes U.S. Patent 7,874,487 owned by the Company (the "'487 patent”). The lawsuit sought to prohibit Code from manufacturing the product, and Microscan from selling and distributing the product. In August 2014, Microscan filed a lawsuit against the Company in the United States District Court for the Southern District of New York alleging that the Company’s DataMan ® 8500 handheld imager infringes U.S. Patent 6,352,204 owned by Microscan (the “'204 patent”). The lawsuit sought to prohibit the Company from manufacturing, selling, and distributing the DataMan ® 7500, 8500, 8600, and 9500 products. In June 2015, the Company executed a settlement agreement with Microscan requiring a payment by the Company of $3,500,000 which settles all outstanding litigation between the parties. The settlement included a patent license agreement valued at $1,667,000 that allows the Company to continue producing current models of its handheld barcode readers, which was recorded as an asset and is being amortized to cost of revenue over the five year life of the patent. The remaining $1,833,000 of the settlement was recorded as expense. All cases were dismissed by the end of July 2015. In July 2015, the Company also executed an immaterial settlement agreement with Code. This matter is now closed. Various other claims and legal proceedings generally incidental to the normal course of business are pending or threatened on behalf of or against the Company, including some pertaining to the Company’s recently divested surface inspection business, which arose prior to the transaction closing date and for which the Company retains liability pursuant to the agreement governing such divestiture. While we cannot predict the outcome of these matters, we believe that any liability arising from them will not have a material adverse effect on our financial position, liquidity, or results of operations. |

Guarantees [Abstract] | |
Indemnification Provisions | Indemnification Provisions Except as limited by Massachusetts law, the by-laws of the Company require it to indemnify certain current or former directors, officers, and employees of the Company against expenses incurred by them in connection with each proceeding in which he or she is involved as a result of serving or having served in certain capacities. Indemnification is not available with respect to a proceeding as to which it has been adjudicated that the person did not act in good faith in the reasonable belief that the action was in the best interests of the Company. The maximum potential amount of future payments the Company could be required to make under these provisions is unlimited. The Company has never incurred significant costs related to these indemnification provisions. As a result, the Company believes the estimated fair value of these provisions is not material. In the ordinary course of business, the Company may accept standard limited indemnification provisions in connection with the sale of its products, whereby it indemnifies its customers for certain direct damages incurred in connection with third-party patent or other intellectual property infringement claims with respect to the use of the Company’s products.The maximum potential amount of future payments the Company could be required to make under these provisions is generally subject to fixed monetary limits. The Company has never incurred significant costs to defend lawsuits or settle claims related to these indemnification provisions. As a result, the Company believes the estimated fair value of these provisions is not material. In the ordinary course of business, the Company also accepts limited indemnification provisions from time to time, whereby it indemnifies customers for certain direct damages incurred in connection with bodily injury and property damage arising from the use of the Company’s products.The maximum potential amount of future payments the Company could be required to make under these provisions is generally limited and is likely recoverable under the Company’s insurance policies. As a result of this coverage, and the fact that the Company has never incurred significant costs to defend lawsuits or settle claims related to these indemnification provisions, the Company believes the estimated fair value of these provisions is not material. Under the terms of the Company’s sale of its Surface Inspection Systems Division to AMETEK, Inc., the Company has agreed to retain certain liabilities in connection with its business dealings occurring prior to the transaction closing date of July 6, 2015, and to indemnify AMETEK, Inc. in connection with these retained liabilities and for any breach of the representations and warranties made by the Company to AMETEK, Inc. in connection with the sales agreement itself, as is usual and customary in such transactions. As of the date of this report, the Company believes the estimated fair value of these provisions is not material. |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivative Instruments | Derivative Instruments The Company’s foreign currency risk management strategy is principally designed to mitigate the potential financial impact of changes in the value of transactions and balances denominated in foreign currencies resulting from changes in foreign currency exchange rates. Currently, the Company enters into two types of hedges to manage this risk. The first are economic hedges which utilize foreign currency forward contracts with maturities of up to 45 days to manage the exposure to fluctuations in foreign currency exchange rates arising primarily from foreign-denominated receivables and payables. The gains and losses on these derivatives are intended to be offset by the changes in the fair value of the assets and liabilities being hedged. These economic hedges are not designated as hedging instruments for hedge accounting treatment. The second are cash flow hedges which utilize foreign currency forward contracts with maturities of up to 18 months to hedge specific forecasted transactions of the Company's foreign subsidiaries with the goal of protecting our budgeted revenues and expenses against foreign currency exchange rate changes compared to our budgeted rates. These cash flow hedges are designated as hedging instruments for hedge accounting treatment.

Equity [Abstract] | |
Shareholders’ Equity | Shareholders’ Equity Preferred Stock The Company has 400,000 shares of authorized but unissued $.01 par value preferred stock. Common Stock Each outstanding share of common stock entitles the record holder to one vote on all matters submitted to a vote of the Company’s shareholders. Common shareholders are also entitled to dividends when and if declared by the Company’s Board of Directors. Shareholder Rights Plan The Company has adopted a Shareholder Rights Plan, the purpose of which is, among other things, to enhance the Board of Directors’ ability to protect shareholder interests and to ensure that shareholders receive fair treatment in the event any coercive takeover attempt of the Company is made in the future. The Shareholder Rights Plan could make it more difficult for a third party to acquire, or could discourage a third party from acquiring, the Company or a large block of the Company’s common stock. The following summary description of the Shareholder Rights Plan does not purport to be complete and is qualified in its entirety by reference to the Company’s Shareholder Rights Plan, which has been previously filed by the Company with the Securities and Exchange Commission as an exhibit to a Registration Statement on Form 8-A filed on December 5, 2008. In connection with the adoption of the Shareholder Rights Plan, the Board of Directors of the Company declared a dividend distribution of one purchase right (a “Right”) for each outstanding share of common stock to shareholders of record as of the close of business on December 5, 2008. The Rights currently are not exercisable and are attached to and trade with the outstanding shares of common stock. Under the Shareholder Rights Plan, the Rights become exercisable if a person becomes an “acquiring person” by acquiring 15% or more of the outstanding shares of common stock or if a person commences a tender offer that would result in that person owning 15% or more of the common stock. If a person becomes an “acquiring person,” each holder of a Right (other than the acquiring person) would be entitled to purchase, at the then-current exercise price, such number of shares of the Company’s preferred stock which are equivalent to shares of common stock having twice the exercise price of the Right. If the Company is acquired in a merger or other business combination transaction after any such event, each holder of a Right would then be entitled to purchase, at the then-current exercise price, shares of the acquiring company’s common stock having a value of twice the exercise price of the Right. Stock Repurchases In April 2014, the Company's Board of Directors authorized the repurchase of $50,000,000 of the Company's common stock. As of December 31, 2015, the Company repurchased 1,079,000 shares at a cost of $50,000,000 under this program, including 895,000 shares at a cost of $42,415,000 in 2015. Stock repurchases under this 2014 program are now complete. In August 2015, the Company's Board of Directors authorized the repurchase of an additional $100,000,000 of the Company's common stock. Purchases under this 2015 program began in the third quarter of 2015 upon completion of the 2014 program. As of December 31, 2015, the Company repurchased 2,311,000 shares at a cost of $83,936,000 under this program. Total stock repurchases in 2015 amounted to $126,351,000 . In November, 2015, the Company's Board of Directors authorized the repurchase of an additional $100,000,000 of the Company's common stock. Purchases under this November 2015 program will commence upon completion of the August 2015 program. The Company may repurchase shares under these programs in future periods depending on a variety of factors, including, among other things, the impact of dilution from employee stock options, stock price, share availability, and cash requirements. Dividends The Company’s Board of Directors declared and paid cash dividends of $0.07 per share in the second, third, and fourth quarters of 2015. Total cash dividends paid in 2015 amounted to $18,062,000 . The cash dividend in the second quarter of 2015 was the first dividend declared and paid since the fourth quarter of 2012 when the Company’s Board of Directors accelerated dividends in advance of an increase in the federal tax on dividends paid after December 31, 2012. Due to these accelerated payments, no cash dividends were declared or paid in 2013, 2014, or the first quarter of 2015. Future dividends will be declared at the discretion of the Company's Board of Directors and will depend upon such factors as the Board deems relevant, including, among other things, the Company's ability to generate positive cash flow from operations. |

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |
Stock-Based Compensation | Stock-Based Compensation Stock Option Plans The Company’s share-based payments that result in compensation expense consist of stock option grants and restricted stock awards. As of December 31, 2015 , the Company had 9,844,051 shares available for grant. Stock options are granted with an exercise price equal to the market value of the Company’s common stock at the grant date and generally vest over four years based upon continuous service and expire ten years from the grant date. Conditions of restricted stock awards may be based upon continuing employment and/or achievement of pre-established performance goals and objectives. Vesting for performance-based restricted stock awards and time-based restricted stock awards must be greater than one year and three years, respectively. The following table summarizes the Company’s stock option activity for the year ended December 31, 2015 : Shares (in thousands) Weighted- Average Exercise Price Weighted- Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding as of December 31, 2014 6,812 $ 23.26 Granted 1,519 41.00 Exercised (1,520 ) 18.14 Forfeited or expired (167 ) 31.94 Outstanding as of December 31, 2015 6,644 $ 28.27 7.11 $ 57,955 Exercisable as of December 31, 2015 2,596 $ 17.69 5.31 $ 43,597 Options vested or expected to vest at 6,065 $ 27.29 6.96 $ 57,291 (1) In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. Options expected to vest are calculated by applying an estimated forfeiture rate to the unvested options. The fair values of stock options granted in each period presented were estimated using the following weighted-average assumptions: Year Ended December 31, 2015 2014 2013 Risk-free rate 2.1 % 2.6 % 2.0 % Expected dividend yield 1.25 % — % — % Expected volatility 40 % 41 % 42 % Expected term (in years) 5.4 5.4 5.8 Risk-free rate The risk-free rate was based upon a treasury instrument whose term was consistent with the contractual term of the option. Expected dividend yield Generally, the current dividend yield is calculated by annualizing the cash dividend declared by the Company’s Board of Directors and dividing that result by the closing stock price on the grant date. However, in the fourth quarter of 2012, the Company paid the full annual dividends for 2013 and 2014 in advance, and therefore, the dividend yield for those years was adjusted to zero. A dividend yield of 1.25% was estimated for future periods from 2015 through the expected life of the option. Expected volatility The expected volatility was based upon a combination of historical volatility of the Company’s common stock over the contractual term of the option and implied volatility for traded options of the Company’s stock. Expected term The expected term was derived from the binomial lattice model from the impact of events that trigger exercises over time. The Company stratifies its employee population into two groups: one consisting of senior management and another consisting of all other employees. The Company currently expects that approximately 74% of its stock options granted to senior management and 73% of its options granted to all other employees will actually vest. Therefore, the Company currently applies an estimated forfeiture rate of 10% to all unvested options for senior management and a rate of 11% for all other employees. The Company revised its estimated forfeiture rates in the first quarter of 2015 , 2014 and 2013 , resulting in an increase to compensation expense of $461,000 , $288,000 , and $300,000 in 2015 , 2014 , and 2013 , respectively. The weighted-average grant-date fair value of stock options granted was $14.35 in 2015 , $15.97 in 2014 , and $8.21 in 2013 . The total intrinsic value of stock options exercised was $43,987,000 in 2015 , $31,884,000 in 2014 , and $32,096,000 in 2013 . The total fair value of stock options vested was $16,227,000 in 2015 , $11,627,000 in 2014 , and $9,717,000 in 2013 . As of December 31, 2015 , total unrecognized compensation expense related to non-vested stock options was $18,785,000 , which is expected to be recognized over a weighted-average period of 1.54 years. The following table summarizes the Company's restricted stock activity for the year ended December 31, 2015: Shares (in thousands) Weighted-Average Grant Fair Value Aggregate Intrinsic Value (in thousands) (1) Nonvested as of December 31, 2014 20 $ 34.05 Granted — — Vested — — Forfeited or expired — — Nonvested as of December 31, 2015 20 $ 34.05 $ 675 (1) Fair market value as of December 31, 2015. The fair values of restricted stock awards granted were determined based upon the market value of the Company's common stock at the time of grant. The initial cost is then amortized over the period of vesting until the restrictions lapse. These restricted shares will be fully vested in 2018. Participants are entitled to dividends on restricted stock awards, but only receive those amounts if the shares vest. The sale or transfer of these shares is restricted during the vesting period.

Interest and penalties included in these amounts was a decrease to tax expense of $148,000 . The effective tax rate for 2014 included the impact of the following discrete tax events: (1) a decrease in tax expense of $652,000 from the final true-up on the prior year’s tax accrual upon filing the actual tax returns, (2) a decrease in tax expense, net of reserves, of $645,000 from the retroactive application of the 2014 research and development tax credit passed by Congress in December 2014 and applied retroactively to January 1, 2014, (3) a decrease in tax expense of $418,000 from the closing of the Internal Revenue Service audit of the Company for tax years 2010 and 2011, and (4) a decrease in tax expense of $217,000 from the expiration of the statutes of limitations for certain reserves for income tax uncertainties.

Interest and penalties included in these amounts was a decrease to tax expense of $854,000 . The changes in the reserve for income taxes, excluding gross interest and penalties, were as follows (in thousands): Balance of reserve for income taxes as of December 31, 2013 $ 4,408 Gross amounts of decreases in unrecognized tax benefits as a result of tax positions taken in prior periods (226 ) Gross amounts of increases in unrecognized tax benefits as a result of tax positions taken in the current period 1,095 Gross amounts of decreases in unrecognized tax benefits relating to settlements with taxing authorities (15 ) Gross amounts of decreases in unrecognized tax benefits as a result of the expiration of the applicable statutes of limitations (135 ) Balance of reserve for income taxes as of December 31, 2014 5,127 Gross amounts of decreases in unrecognized tax benefits as a result of tax positions taken in prior periods (56 ) Gross amounts of increases in unrecognized tax benefits as a result of tax positions taken in the current period 1,291 Gross amounts of decreases in unrecognized tax benefits relating to settlements with taxing authorities — Gross amounts of decreases in unrecognized tax benefits as a result of the expiration of the applicable statutes of limitations (1,066 ) Balance of reserve for income taxes as of December 31, 2015 $ 5,296 The Company’s reserve for income taxes, including gross interest and penalties, was $5,858,000 as of December 31, 2015, which included $4,830,000 classified as a non-current liability and $1,028,000 recorded as a reduction to non-current deferred tax assets. The Company's reserve for income taxes, including gross interest and penalties, was $5,651,000 as of December 31, 2014, which included $4,623,000 classified as a non-current liability and $1,028,000 recorded as a reduction to non-current deferred tax assets. The amount of gross interest and penalties included in these balances was $562,000 and $524,000 as of December 31, 2015 and December 31, 2014, respectively. If the Company’s tax positions were sustained or the statutes of limitations related to certain positions expired, these reserves would be released and income tax expense would be reduced in a future period, less $701,000 and $664,000 , as of December 31, 2015 and December 31, 2014, respectively, that would be recorded through additional paid-in capital. As a result of the expiration of certain statutes of limitations, there is a potential that a portion of these reserves could be released, which would decrease income tax expense by approximately $750,000 to $850,000 over the next twelve months. The Company has defined its major tax jurisdictions as the United States, Ireland, China, and Japan, and within the United States, Massachusetts and California. Within the United States, the tax years 2012 through 2014 remain open to examination by the Internal Revenue Service, while the tax years 2011 through 2014 remain open to various state taxing authorities, and the tax years 2011 through 2014 remain open to examination by various taxing authorities in other jurisdictions in which the Company operates. In 2011, the Company finalized an Advanced Pricing Agreement (APA) with Japan that will cover tax years 2006 through 2011, with a requested extension to 2012. The Company has concluded negotiations for an APA between Japan and Ireland that will cover tax years 2014 through 2018 with retroactive application to 2013. The Company believes it is adequately reserved for these open years. Deferred tax assets and liabilities consisted of the following (in thousands): December 31, 2015 2014 Current deferred tax assets: Inventory and revenue related $ 2,985 $ 4,911 Bonuses, commissions, and other compensation 2,500 2,280 Other 1,619 1,794 Net current deferred tax assets $ 7,104 $ 8,985 Non-current deferred tax assets: Stock-based compensation expense $ 13,895 $ 10,290 Federal and state tax credit carryforwards 5,091 4,547 Depreciation 2,328 1,945 Other 2,556 2,583 Gross non-current deferred tax assets 23,870 19,365 Non-current deferred tax liabilities: Nondeductible intangible assets (1,198 ) (2,430 ) Gross non-current deferred tax liabilities (1,198 ) (2,430 ) Valuation allowance (3,259 ) (2,483 ) Net non-current deferred tax assets $ 19,413 $ 14,452 Current deferred tax liabilities: Other $ (319 ) $ — Net current deferred tax liabilities $ (319 ) $ — In 2015, the Company recorded a valuation allowance of $776,000 for state research and development tax credits that were not considered to be realizable. Should these credits be utilized in a future period, the reserve associated with these credits would be reversed in the period when it is determined that the credits can be utilized to offset future state income tax liabilities. In addition, the Company had $6,119,000 of state research and development tax credit carryforwards, net of federal tax, as of December 31, 2015 , which will begin to expire in 2017. The Company recorded certain intangible assets as a result of the acquisition of DVT Corporation in 2005. The amortization of these intangible assets is not deductible for U.S. tax purposes. A deferred tax liability was established to reflect the federal and state liability associated with not deducting the acquisition-related amortization expenses. The balance of this liability was $1,198,000 as of December 31, 2015 . While the deferred tax assets, net of valuation allowance, are not assured of realization, management has evaluated the realizability of these deferred tax assets and has determined that it is more likely than not that these assets will be realized. In reaching this conclusion, we have evaluated certain relevant criteria including the Company’s historical profitability, current projections of future profitability, and the lives of tax credits, net operating losses, and other carryforwards. Should the Company fail to generate sufficient pre-tax profits in future periods, we may be required to establish valuation allowances against these deferred tax assets, resulting in a charge to current operations in the period of determination. The Company does not provide U.S. income taxes on its foreign subsidiaries’ undistributed earnings, as they are deemed to be permanently reinvested outside the United States. Upon repatriation, the Company would provide the appropriate U.S. income taxes on these earnings, net of applicable foreign tax credits. It is not practicable to determine the income tax liability that might be incurred if the earnings were to be distributed. The Company recorded $354,000 of other income in 2013 upon the expiration of the statutes of limitations relating to tax holidays, during which time the Company collected value-added taxes from customers that were not required to be remitted to the government authority. On July 6, 2015, the Company completed the sale of its Surface Inspection Systems Division (SISD). A pre-tax gain of $125,357,000 and associated income tax expense of $47,175,000 was recorded in 2015. Cash paid for income taxes totaled $58,280,000 in 2015 , $17,549,000 in 2014 , and $8,831,000 in 2013 . The 2015 income tax payments included remittances related to the sale of SISD. |

Acquisition of Selected Assets of Manatee Works, Inc. | Acquisition of Selected Assets of Manatee Works, Inc. On August 21, 2015, the Company acquired selected assets of Manatee Works, Inc. (Manatee), a privately-held U.S.-based developer of barcode scanning software development kits (SDKs). The Company plans to leverage Manatee's current developer network and business model of attracting new developers to drive leads for its ID products. Under this transaction, the Company also acquired technology for use in mobile devices. The Company paid $1,023,000 in cash upon closing and may pay additional contingent cash consideration over the next three years based upon certain milestone revenue levels. The undiscounted potential outcomes related to the contingent consideration range from $0 to approximately $5,000,000 . The fair value of the contingent consideration as of the acquisition date was $3,790,000 , resulting in a total purchase price of $4,813,000 . The contingent consideration is remeasured each reporting period with changes in fair value recorded in "Other income (expense)" on the Consolidated Statements of Operations. The fair value as of December 31, 2015 was $3,000,000 , and accordingly, the liability was reduced by $790,000 and this benefit was recorded in other income. As of December 31, 2015, the current portion of contingent consideration expected to be paid within the next year was $600,000 and was recorded in “Accrued expenses,” and the non-current portion expected to be paid beyond one year was $2,400,000 and was recorded in “Other non-current liabilities” on the Consolidated Balance Sheets. The purchase price was allocated as follows (in thousands): Prepaid expenses $ 23 Customer relationships 140 Completed technology 590 Goodwill 4,060 Purchase price $ 4,813 The customer relationships and completed technology are included in "Intangible assets" on the Consolidated Balance Sheets.

Accounting Policies [Abstract] | |
Nature of Operations | Nature of Operations Cognex Corporation is a leading provider of machine vision products that capture and analyze visual information in order to automate tasks, primarily in manufacturing processes, where vision is required. |
Use of Estimates in the Preparation of Financial Statements | Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and judgments that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities as of the balance sheet date, and the reported amounts of revenues and expenses during the year. Actual results could differ from those estimates. Significant estimates and judgments include those related to revenue recognition, investments, accounts receivable, inventories, long-lived assets, goodwill, warranty obligations, contingencies, stock-based compensation, income taxes and derivative instruments |
Basis of Consolidation | Basis of Consolidation The consolidated financial statements include the accounts of Cognex Corporation and its subsidiaries, all of which are wholly-owned. All intercompany accounts and transactions have been eliminated. |
Foreign Currency | Foreign Currency Translation The financial statements of the Company’s foreign subsidiaries, where the local currency is the functional currency, are translated using exchange rates in effect at the end of the year for assets and liabilities and average exchange rates during the year for results of operations. The resulting foreign currency translation adjustment, net of tax, is recorded in shareholders’ equity as other comprehensive income (loss). |
Fair Value Measurements | Fair Value Measurements The Company applies a three-level valuation hierarchy for fair value measurements. The categorization of assets and liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the measurement of fair value. Level 1 inputs to the valuation methodology utilize unadjusted quoted market prices in active markets for identical assets and liabilities. Level 2 inputs to the valuation methodology are other observable inputs, including quoted market prices for similar assets and liabilities, quoted prices for identical and similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 inputs to the valuation methodology are unobservable inputs based upon management’s best estimate of the inputs that market participants would use in pricing the asset or liability at the measurement date, including assumptions about risk. A change to the level of an asset or liability within the fair value hierarchy is determined at the end of a reporting period. |
Cash, Cash Equivalents, and Investments | Cash, Cash Equivalents, and Investments Money market instruments purchased with original maturities of three months or less are classified as cash equivalents and are stated at amortized cost. Debt securities with original maturities greater than three months and remaining maturities of one year or less are classified as short-term investments, as well as equity securities that the Company intends to sell within one year. Debt securities with remaining maturities greater than one year, as well as a limited partnership interest, are classified as long-term investments. It is the Company’s policy to invest in debt securities with effective maturities that do not exceed ten years. Debt securities with original maturities greater than three months are designated as available-for-sale and are reported at fair value, with unrealized gains and losses, net of tax, recorded in shareholders’ equity as other comprehensive income (loss). Equity securities that are held for short periods of time with the intention of selling them in the near term are designated as trading and are reported at fair value, with unrealized gains and losses recorded in current operations. Realized gains and losses are included in current operations, along with the amortization of the discount or premium on debt securities arising at acquisition, and are calculated using the specific identification method. The Company’s limited partnership interest is accounted for using the cost method because the Company’s investment is less than 5% of the partnership and the Company has no influence over the partnership’s operating and financial policies. Management monitors the carrying value of its investments in debt securities and a limited partnership interest compared to their fair value to determine whether an other-than-temporary impairment has occurred. If the fair value of a debt security is less than its amortized cost, the Company assesses whether the impairment is other-than-temporary. In considering whether a decline in fair value is other-than-temporary, we consider many factors. In its evaluation of its debt securities, management considers the type of security, the credit rating of the security, the length of time the security has been in a loss position, the size of the loss position, our intent and ability to hold the security to expected recovery of value, and other meaningful information. An impairment is considered other-than-temporary if (i) the Company has the intent to sell the security, (ii) it is more likely than not that the Company will be required to sell the security before recovery of the entire amortized cost basis, or (iii) the Company does not expect to recover the entire amortized cost basis of the security. If impairment is considered other-than-temporary based upon condition (i) or (ii) described above, the entire difference between the amortized cost and the fair value of the security is recognized in current operations. If an impairment is considered other-than-temporary based upon condition (iii), the amount representing credit losses (defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis of the security) is recognized in current operations and the amount relating to all other factors is recognized in shareholders' equity as other comprehensive income (loss). In its evaluation of its limited partnership interest, management considers the duration and extent of the decline, the length of the Company’s commitment to the investment, general economic trends, and specific communications with the General Partner. |
Accounts Receivable | Accounts Receivable The Company extends credit with various payment terms to customers based upon an evaluation of their financial condition. Accounts that are outstanding longer than the payment terms are considered to be past due. The Company establishes reserves against accounts receivable for potential credit losses and records bad debt expense in current operations when it determines receivables are at risk for collection based upon the length of time the receivable has been outstanding, the customer’s current ability to pay its obligations to the Company, general economic and industry conditions, as well as various other factors. Receivables are written off against these reserves in the period they are determined to be uncollectible and payments subsequently received on previously written-off receivables are recorded as a reversal of the bad debt expense. |
Inventories | Inventories Inventories are stated at the lower of cost or market. Cost is determined using standard costs, which approximates actual costs under the first-in, first-out (FIFO) method. The Company’s inventory is subject to rapid technological change or obsolescence. The Company reviews inventory quantities on hand and estimates excess and obsolescence exposures based upon assumptions about future demand, product transitions, and market conditions, and records reserves to reduce the carrying value of inventories to their net realizable value. If actual future demand is less than estimated, additional inventory write-downs would be required. The Company generally disposes of obsolete inventory upon determination of obsolescence. The Company does not dispose of excess inventory immediately, due to the possibility that some of this inventory could be sold to customers as a result of differences between actual and forecasted demand. When inventory has been written down below cost, such reduced amount is considered the new cost basis for subsequent accounting purposes. As a result, the Company would recognize a higher than normal gross margin if the reserved inventory were subsequently sold. |
Property, Plant, and Equipment | Property, Plant, and Equipment Property, plant, and equipment are stated at cost and depreciated using the straight-line method over the assets’ estimated useful lives. Buildings’ useful lives are 39 years, building improvements’ useful lives are ten years, and the useful lives of computer hardware and software, manufacturing test equipment, and furniture and fixtures range from two to five years. Leasehold improvements are depreciated over the shorter of the estimated useful lives or the remaining terms of the leases. Maintenance and repairs are expensed when incurred; additions and improvements are capitalized. Upon retirement or disposition, the cost and related accumulated depreciation of the disposed assets are removed from the accounts, with any resulting gain or loss included in current operations. |
Intangible Assets | Intangible Assets Intangible assets are stated at cost and amortized over the assets’ estimated useful lives. Intangible assets are either amortized in relation to the relative cash flows anticipated from the intangible asset or using the straight-line method, depending upon facts and circumstances. The useful lives of distribution networks range from eleven to twelve years, of customer contracts and relationships from five to twelve years, and of completed technologies and other intangible assets from three to eight years. The Company evaluates the possible impairment of long-lived assets, including intangible assets, whenever events or circumstances indicate the carrying value of the assets may not be recoverable. At the occurrence of a certain event or change in circumstances, the Company evaluates the potential impairment of an asset by estimating the future undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the sum of the estimated future cash flows is less than the carrying value, the Company determines the amount of such impairment by comparing the fair value of the asset to its carrying value. The fair value is based upon the present value of the estimated future cash flows using a discount rate commensurate with the risks involved. |
Goodwill | Goodwill Goodwill is stated at cost. The Company evaluates the possible impairment of goodwill annually each fourth quarter and whenever events or circumstances indicate the carrying value of the goodwill may not be recoverable. For the past five years, the Company has performed a qualitative assessment of goodwill (commonly known as “step zero”) to determine whether further impairment testing is necessary. Factors that management considers in this assessment include macroeconomic conditions, industry and market considerations, overall financial performance (both current and projected), changes in management or strategy, and changes in the composition or carrying amount of net assets. In addition, management takes into consideration the goodwill valuation under the last quantitative analysis that was performed. If this qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the entity would proceed to a two-step process. Step one compares the fair value of the reporting unit with its carrying value, including goodwill. If the carrying amount exceeds the fair value of the reporting unit, step two is required to measure the amount of impairment loss. Step two compares the implied fair value of the reporting unit goodwill to the carrying amount of the goodwill. |
Warranty Obligations | Warranty Obligations The Company warrants its products to be free from defects in material and workmanship for periods primarily ranging from one to three years from the time of sale based upon the product being purchased and the terms of the customer arrangement. Warranty obligations are evaluated and recorded at the time of sale since it is probable that customers will make claims under warranties related to products that have been sold and the amount of these claims can be reasonably estimated based upon historical costs to fulfill claims. Obligations may also be recorded subsequent to the time of sale whenever specific events or circumstances impacting product quality become known that would not have been taken into account using historical data. |
Contingencies | Contingencies Loss contingencies are accrued if the loss is probable and the amount of the loss can be reasonably estimated. Legal costs associated with potential loss contingencies, such as patent infringement matters, are expensed as incurred. |
Revenue Recognition | Revenue Recognition The Company’s product revenue is derived from the sale of machine vision systems, which can take the form of hardware with embedded software or software-only, and related accessories. The Company also generates revenue by providing maintenance and support, consulting, and training services to its customers. Certain of the Company’s arrangements include multiple deliverables that provide the customer with a combination of products or services. In order to recognize revenue, the Company requires that a signed customer contract or purchase order is received, the fee from the arrangement is fixed or determinable, and collection of the resulting receivable is probable. Assuming that these criteria have been met, product revenue is generally recognized upon delivery, revenue from maintenance and support programs is recognized ratably over the program period, and revenue from consulting and training services is recognized when the services have been provided. When customer-specified acceptance criteria exists that are substantive, product revenue is deferred until these criteria have been met, along with the associated incremental direct costs. The majority of the Company’s product offerings consist of hardware with embedded software. Under the revenue recognition rules for tangible products, the fee from a multiple-deliverable arrangement is allocated to each of the deliverables based upon their relative selling prices as determined by a selling-price hierarchy. A deliverable in an arrangement qualifies as a separate unit of accounting if the delivered item has value to the customer on a stand-alone basis. A delivered item that does not qualify as a separate unit of accounting is combined with the other undelivered items in the arrangement and revenue is recognized for those combined deliverables as a single unit of accounting. The selling price used for each deliverable is based upon vendor-specific objective evidence (VSOE) if available, third-party evidence (TPE) if VSOE is not available, and management’s best estimate of selling price (BESP) if neither VSOE nor TPE are available. VSOE is the price charged for a deliverable when it is sold separately. TPE is the price of the Company’s or any competitor’s largely interchangeable products or services in stand-alone sales to similarly-situated customers. BESP is the price at which the Company would sell the deliverable if it were sold regularly on a stand-alone basis, considering market conditions and entity-specific factors. The selling prices used in the relative selling price allocation method for (1) certain of the Company’s services are based upon VSOE, (2) third-party accessories available from other vendors are based upon TPE, and (3) hardware products with embedded software, custom accessories, and services for which VSOE does not exist are based upon BESP. The Company does not believe TPE exists for these products and services because they are differentiated from competing products and services in terms of functionality and performance and there are no competing products or services that are largely interchangeable. BESP has been established for each product line within each region. Management establishes BESP with consideration for market conditions, such as the impact of competition and geographic considerations, and entity-specific factors, such as pricing practices, gross margin objectives, customer size, and market share goals. Management believes that BESP is reflective of reasonable pricing of that deliverable as if priced on a stand-alone basis. Under the revenue recognition rules for software-only products, the fee from a multiple-deliverable arrangement is allocated to each of the undelivered elements based upon VSOE, which is limited to the price charged when the same deliverable is sold separately, with the residual value from the arrangement allocated to the delivered element. The portion of the fee that is allocated to each deliverable is then recognized as revenue when the criteria for revenue recognition are met with respect to that deliverable. If VSOE does not exist for all of the undelivered elements, then all revenue from the arrangement is typically deferred until all elements have been delivered to the customer. The Company’s products are sold directly to end users, as well as to resellers including original equipment manufacturers (OEMs), distributors, and integrators. Revenue is recognized upon delivery of the product to the reseller, assuming all other revenue recognition criteria have been met. The Company establishes reserves against revenue for potential product returns, since the amount of future returns can be reasonably estimated based upon experience. These reserves have historically been immaterial. Amounts billed to customers related to shipping and handling, as well as reimbursements received from customers for out-of-pocket expenses, are classified as revenue, with the associated costs included in cost of revenue. |
Research and Development | Research and Development Research and development costs for internally-developed or acquired products are expensed when incurred until technological feasibility has been established for the product. Thereafter, all software costs may be capitalized until the product is available for general release to customers. The Company determines technological feasibility at the time the product reaches beta in its stage of development. Historically, the time incurred between beta and general release to customers has been short, and therefore, the costs have been insignificant. |
Advertising Costs | Advertising Costs Advertising costs are expensed as incurred and totaled $2,009,000 in 2015 , $2,609,000 in 2014 , and $2,219,000 in 2013 . |
Stock-Based Compensation | Stock-Based Compensation The Company’s share-based payments that result in compensation expense consist of stock option grants and restricted stock awards. The Company has reserved a specific number of shares of its authorized but unissued shares for issuance upon the exercise of stock options or the granting of restricted stock. When a stock option is exercised or a restricted stock award is granted, the Company issues new shares from this pool. The fair values of stock options are estimated on the grant date using a binomial lattice model. Management is responsible for determining the appropriate valuation model and estimating these fair values, and in doing so, considers a number of factors, including information provided by an outside valuation advisor. The Company recognizes compensation expense related to stock options using the graded attribution method, in which expense is recognized on a straight-line basis over the service period for each separately vesting portion of the stock option as if the option was, in substance, multiple awards. The amount of compensation expense recognized at the end of the vesting period is based upon the number of stock options for which the requisite service has been completed. No compensation expense is recognized for options that are forfeited for which the employee does not render the requisite service. The term “forfeitures” is distinct from “expirations” and represents only the unvested portion of the surrendered option. The Company applies estimated forfeiture rates to its unvested options to arrive at the amount of compensation expense that is expected to be recognized over the requisite service period. At the end of each separately vesting portion of an option, the expense that was recognized by applying the estimated forfeiture rate is compared to the expense that should be recognized based upon the employee’s service, and a credit to expense is recorded related to those employees that have not rendered the requisite service. |
Taxes | Taxes The Company recognizes a tax position in its financial statements when that tax position, based solely upon its technical merits, is more likely than not to be sustained upon examination by the relevant taxing authority. Those tax positions failing to qualify for initial recognition are recognized in the first interim period in which they meet the more likely than not standard, or are resolved through negotiation or litigation with the taxing authority, or upon expiration of the statutes of limitations. Derecognition of a tax position that was previously recognized occurs when an entity subsequently determines that a tax position no longer meets the more likely than not threshold of being sustained. Only the portion of the liability that is expected to be paid within one year is classified as a current liability. As a result, liabilities expected to be resolved without the payment of cash (e.g., resolution due to the expiration of the statutes of limitations) or are not expected to be paid within one year are not classified as current. It is the Company’s policy to record estimated interest and penalties as income tax expense and tax credits as a reduction in income tax expense. Deferred tax assets and liabilities are determined based upon the differences between the financial statement and tax bases of assets and liabilities as measured by the enacted tax rates that will be in effect when these differences reverse. Valuation allowances are provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. Sales tax in the United States and similar taxes in other jurisdictions that are collected from customers and remitted to government authorities are presented on a gross basis (i.e., a receivable from the customer with a corresponding payable to the government). Amounts collected from customers and retained by the Company during tax holidays are recognized as non-operating income when earned. |
Net Income Per Share | Net Income Per Share Basic net income per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted net income per share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding for the period plus potential dilutive common shares. Dilutive common equivalent shares consist of stock options and are calculated using the treasury stock method. Common equivalent shares do not qualify as participating securities. In periods where the Company records a net loss, potential common stock equivalents are not included in the calculation of diluted net loss per share. |
Comprehensive Income | Comprehensive Income Comprehensive income is defined as the change in equity of a company during a period from transactions and other events and circumstances, excluding transactions resulting from investments by owners and distributions to owners. Accumulated other comprehensive loss, net of tax, as of December 31, 2015 and December 31, 2014 , consists of foreign currency translation adjustments of $49,646,000 and $38,030,000 , respectively; net unrealized losses on available-for-sale investments of $1,413,000 and $130,000 , respectively; net unrealized gains on derivative instruments of $ 206,000 and $ 32,000 , respectively; and losses on currency swaps, net of gains on long-term intercompany loans, of $1,271,000 and $ 1,271,000 , respectively. Amounts reclassified from accumulated other comprehensive income to investment income on the Consolidated Statements of Operations were net realized gains of $344,000 , $673,000 , and $314,000 for 2015 , 2014 , and 2013 , respectively. |
Concentrations of Risk | Concentrations of Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, investments, and trade receivables. The Company has certain domestic and foreign cash balances that exceed the insured limits set by the Federal Deposit Insurance Corporation (FDIC) in the United States and equivalent regulatory agencies in foreign countries. The Company primarily invests in investment-grade debt securities and has established guidelines relative to credit ratings, diversification, and maturities of its debt securities that maintain safety and liquidity. The Company has not experienced any significant realized losses on its debt securities. The Company performs ongoing credit evaluations of its customers and maintains allowances for potential credit losses. The Company has not experienced any significant losses related to the collection of its accounts receivable. A significant portion of the Company's product is manufactured by a third-party contractor located in Indonesia. This contractor has agreed to provide Cognex with termination notification periods and last-time-buy rights, if and when that may be applicable. We rely upon this contractor to provide quality product and meet delivery schedules. We engage in extensive product quality programs and processes, including actively monitoring the performance of our third-party manufacturers; however, we may not detect all product quality issues through these programs and processes. Certain components are presently sourced from a single vendor that is selected based on price and performance considerations. In the event of a supply disruption from a single-source vendor, these components may be purchased from an alternative vendor, which may result in manufacturing delays based on the lead time of the new vendor. Certain key electronic and mechanical components that are purchased from strategic suppliers, such as processors or imagers, are fundamental to the design of Cognex products. A disruption in the supply of these key components, such as a last-time-buy announcement, natural disaster, financial bankruptcy, or other event, may require us to purchase a significant amount of inventory at unfavorable prices resulting in lower gross margins and higher risk of carrying excess inventory. If we are unable to secure adequate supply from alternative sources, we may have to redesign our products, which may lead to a delay in manufacturing and a possible loss of sales. |
Derivative Instruments | Derivative Instruments Derivative instruments are recorded on the Consolidated Balance Sheets at fair value. Changes in the fair value of derivatives are recorded each period in current operations or in shareholders' equity as other comprehensive income (loss), depending upon whether the derivative is designated as a hedge transaction and, if it is, the effectiveness of the hedge. At the inception of the contract, the Company designates foreign currency forward exchange contracts as either a cash flow hedge of certain forecasted foreign currency denominated sales and purchase transactions or as an economic hedge. Changes in the fair value of a derivative that is highly effective and that is designated and qualifies as a cash flow hedge are recorded in shareholders' equity as other comprehensive income (loss), and reclassified into current operations in the same period during which the hedged transaction affects current operations and in the same financial statement line item as that of the forecasted transaction. Cash flow hedges are evaluated for effectiveness quarterly. Any hedge ineffectiveness (which represents the amount by which the changes in the fair value of the derivative exceed the variability in the cash flows of the forecasted transaction) is recorded in current operations in the period in which ineffectiveness is determined. Changes in the fair value of the Company’s economic hedges (not designated as a cash flow hedge) are reported in current operations. The cash flows from derivative instruments are presented in the same category on the Consolidated Statements of Cash Flows as the category for the cash flows from the hedged item. Generally, this accounting policy election results in cash flows related to derivative instruments being classified as an operating activity on the Consolidated Statements of Cash Flows. The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as cash flow hedges to specific forecasted transactions. The Company also formally assesses (both at the hedge’s inception and on an ongoing basis) whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the fair value or cash flows of hedged items and whether those derivatives may be expected to remain highly effective in future periods. When it is determined that a derivative is not (or has ceased to be) highly effective as a hedge, the Company discontinues hedge accounting prospectively, as discussed below. The Company discontinues hedge accounting prospectively when (1) it determines that the derivative is no longer effective in offsetting changes in the cash flows of a hedged item; (2) the derivative expires or is sold, terminated, or exercised; (3) it is no longer probable that the forecasted transaction will occur; or (4) management determines that designating the derivative as a hedging instrument is no longer appropriate or desired. When the Company discontinues hedge accounting because it is no longer probable that the forecasted transaction will occur in the originally expected period, the gain or loss on the derivative remains in accumulated other comprehensive income (loss) and is reclassified into current operations when the forecasted transaction affects current operations. However, if it is probable that a forecasted transaction will not occur by the end of the originally specified time period or within an additional two-month period of time thereafter, the gain or loss that was accumulated in other comprehensive income (loss) is recognized immediately in current operations. In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company carries the derivative at fair value on the Consolidated Balance Sheets, recognizing changes in the fair value in current operations, unless it is designated in a new hedging relationship. The Company recognizes all derivative instruments as either current assets or current liabilities at fair value on the Consolidated Balance Sheets. When the Company is engaged in more than one outstanding derivative contract with the same counterparty and also has a legally enforceable master netting agreement with that counterparty, the “net” mark-to-market exposure represents the netting of the positive and negative exposures with that counterparty. Accordingly, cash flow hedges are presented net on the Consolidated Balance Sheets. |
