Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	ORGANIZATION AND BASIS OF PRESENTATION Nature of Business We are a leading supplier of scientific instruments and related services for nanoscale applications and solutions for industry and science. We enable customers to find meaningful answers to questions that accelerate breakthrough discoveries, increase productivity, and ultimately change the world. We design, manufacture, and support the broadest range of high-performance microscopy workflows that provide images and answers in the micro-, nano-, and picometer scales. Combining hardware and software expertise in electron, ion, and light microscopy with deep application knowledge in the materials science, life sciences, semiconductor, and oil & gas markets, we are dedicated to our customers’ pursuit of discovery and resolution to global challenges. We report our revenue based on a group structure organization, which we categorize as the Industry Group and the Science Group. Our significant research and development and manufacturing operations are located in Hillsboro, Oregon; Eindhoven, The Netherlands; and Brno, Czech Republic; and our software development is managed principally from Bordeaux, France. Our sales and service operations are conducted in the United States ( “ U.S. ” ) and approximately 50 other countries around the world. We also sell our products through independent agents, distributors and representatives in additional countries. Basis of Presentation The consolidated financial statements include the accounts of FEI Company and our wholly-owned subsidiaries (collectively, “FEI”). All significant intercompany balances and transactions have been eliminated in consolidation. The accompanying consolidated financial statements and condensed footnotes have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments considered necessary for fair presentation have been included. The results of operations for the thirteen week period ended July 3, 2016 are not necessarily indicative of the results to be expected for the full year. For further information, refer to the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015 , which was filed with the Securities and Exchange Commission on February 22, 2016 . Use of Estimates in Financial Reporting The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Significant accounting policies and estimates underlying the accompanying consolidated financial statements include: • the timing of revenue recognition; • valuations of excess and obsolete inventory; • the lives and recoverability of equipment and other long-lived assets; • the valuation of goodwill; • restructuring and reorganization costs; • tax valuation allowances and unrecognized tax benefits; • stock-based compensation; and • accounting for derivatives. It is reasonably possible that management ’ s estimates may change in the future. Merger Agreement On May 26, 2016, we entered into a definitive agreement to be acquired by Thermo Fisher Scientific Inc. (“Thermo Fisher”) for $107.50 in cash for each share of our common stock (the “Merger”). Completion of the Merger is subject to the satisfaction of various conditions, including approval of the Merger by our shareholders, the absence of certain legal impediments, the absence of a material adverse effect on our business, and the approval of antitrust authorities in China and other foreign jurisdictions. For more information about the Merger, please see the definitive proxy statement on Schedule 14A we filed with the Securities and Exchange Commission on July 27, 2016.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS ASU 2016-12 In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients . The amendments in this update do not change the core principle of the guidance in ASU 2014-09. Rather, the amendments in this update affect only certain narrow aspects of ASU 2014-09. The effective date and transition requirements for the amendments in this ASU are the same as the effective date and transition requirements in ASU 2014-09, Revenue from Contracts with Customers (and any other topic amended by that update). We are evaluating the effect that this standard will have on our consolidated financial statements and related disclosures. ASU 2016-10 In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing . This ASU addresses certain implementation issues that have surfaced since the issuance of ASU No. 2014-09 in May 2014. The ASU provides guidance in identifying performance obligations and determining the appropriate accounting for licensing arrangements. The effective date and transition requirements for the amendments in this ASU are the same as the effective date and transition requirements in ASU 2014-09 (and any other topic amended by that update). We are evaluating the effect that this standard will have on our consolidated financial statements and related disclosures. ASU 2016-09 In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting . The amendment simplifies several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendment is effective for fiscal years beginning after December 15, 2016 with early application permitted, including interim reporting periods within that reporting period, and the new standard will become effective for us on January 1, 2017. We are evaluating the effect that this standard will have on our consolidated financial statements and related disclosures. ASU 2016-02 In February 2016, the FASB issued ASU No. 2016-02, Leases . The amendment improves transparency and comparability among companies by recognizing lease assets and lease liabilities on the balance sheet and by disclosing key information about leasing arrangements. The amendment is effective for fiscal years beginning after December 15, 2018 with early application permitted, including interim reporting periods within that reporting period, and the new standard will become effective for us on January 1, 2019. We are evaluating the effect that this standard will have on our consolidated financial statements and related disclosures. ASU 2015-17 In November 2015, the FASB issued ASU No. 2015-17, Income Taxes: Balance Sheet Classification of Deferred Taxes , which requires presentation of deferred tax assets and liabilities as noncurrent in a classified balance sheet. Early application is permitted for periods beginning after December 15, 2015, including interim reporting periods within that reporting period. The amendments in this update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. We early-adopted the ASU on a prospective basis as of January 1, 2016 and the statement of financial position as of July 3, 2016 reflects the revised classification of current deferred tax assets and liabilities as noncurrent. Adoption of the ASU resulted in an immaterial reclassification between current deferred tax assets and liabilities and non-current deferred tax assets and liabilities. There was no impact on balances in prior periods. There is no other impact on our consolidated financial statements for early-adopting the ASU. ASU 2015-16 In September 2015, the FASB issued ASU No. 2015-16, Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments. The amendment requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. It also requires that the acquirer record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. It eliminates the requirement to retrospectively account for those adjustments. We adopted the ASU on January 1, 2016 however there was no significant impact on our current and previously issued consolidated financial statements. ASU 2015-11 In July 2015, the FASB issued ASU No. 2015-11, Inventory: Simplifying the Measurement of Inventory . An entity using an inventory method other than last-in, first out (“LIFO”) or the retail inventory method should measure inventory at the lower of cost and net realizable value. The new guidance clarifies that net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Early application is permitted for periods beginning after December 15, 2016, including interim reporting periods within that reporting period, and the new standard will become effective for us on January 1, 2017. We are evaluating the effect that this standard will have on our consolidated financial statements and related disclosures. ASU 2014-09 In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers , which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date . Early application is permitted for periods beginning after December 15, 2016, including interim reporting periods within that reporting period, and the new standard will become effective for us on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that this standard will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

Credit Facilities and Restricted Cash	CREDIT FACILITIES AND RESTRICTED CASH Multibank Credit Agreement We have a credit agreement (the “Credit Agreement”), by and among FEI Company, FEI Electron Optics International B.V. (“FEI International”), FEI Electron Optics B.V. (“FEI Electron Optics”, and collectively with FEI Company and FEI International, the “Borrowers”) and DCG Systems, Inc., as Guarantor, the Lenders listed on the signature pages thereof (the “Lenders”) and JPMorgan Chase Bank, N.A., as Administrative Agent (“Agent”). The Credit Agreement provides for a $200.0 million unsecured revolving credit facility, including a $100.0 million subfacility for loans in euros, a $10.0 million subfacility for swingline loans and a $50.0 million subfacility for the issuance of letters of credit. We may, upon notice to Agent, request to increase the revolving loan commitments by an aggregate amount of up to $200.0 million with new or additional commitments subject only to the consent of the Lenders providing the new or additional commitments, for a total unsecured credit facility of up to $400.0 million . The Credit Agreement provides for financial covenants that require us to maintain a minimum interest coverage ratio and limit the maximum leverage that Borrower can maintain at any one time. As of July 3, 2016 , there were no revolving loans or letters of credit outstanding under the Credit Agreement, we were in compliance with all covenants and we were not in default under the Credit Agreement. Credit Facility We have a credit facility agreement (the “Credit Facility”) with HSBC Bank plc (“HSBC”), whereby HSBC has provided us with a revocable, uncommitted credit facility up to an amount of 25.0 million euro. The purpose of this facility is to provide a more efficient means of issuing guarantees to our customers when required by contractual terms. Under the terms of the Credit Facility, when requested, HSBC will issue bank guarantees on behalf of the company and our affiliates. Issuance of the guarantee does not create a liability to the company unless it is called by the customer, at which point we would record a liability for the amount that is due under the guarantee to the bank. As of July 3, 2016 , HSBC has issued $13.5 million in guarantees under the Credit Facility and we have no liabilities outstanding under the Credit Facility. Restricted Cash As part of our contracts with certain customers, we are required to provide letters of credit or bank guarantees which these customers can draw against in the event we do not perform in accordance with our contractual obligations. Bank guarantees and letters of credit outstanding as of July 3, 2016 were approximately $39.7 million . Restricted cash balances securing bank guarantees that expire within 12 months of the balance sheet date are recorded as a current asset on our consolidated balance sheets. Restricted cash balances securing bank guarantees that expire beyond 12 months from the balance sheet date are recorded as long-term restricted cash on our consolidated balance sheets.

Goodwill and Other Intangible Assets	GOODWILL AND INTANGIBLE ASSETS Goodwill The roll-forward of activity related to our goodwill was as follows (in thousands): Twenty-Six Weeks Ended July 3, June 28, Balance, beginning of period $ 145,607 $ 170,773 Goodwill additions 108,002 4,100 Goodwill adjustments 3,672 (6,937 ) Balance, end of period $ 257,281 $ 167,936 Goodwill represents the excess of the purchase price over the estimated fair value of the net assets acquired in connection with our acquisitions. Additions to goodwill represent goodwill from acquisitions made during the period. Adjustments to goodwill include translation adjustments resulting from fluctuations in the value of goodwill held in currencies other than U.S. dollars, as well as adjustments made for the finalization of the purchase price allocations. Acquisition of DCG Systems, Inc. On December 10, 2015 , we acquired 100% of the outstanding shares of DCG Systems, Inc. (“DCG”) for approximately $161.8 million in cash. DCG, with approximately 200 employees and headquarters in Fremont, California, is a leading supplier of electrical fault characterization, localization and editing tools, providing process development, yield ramp and failure analysis applications for a wide range of semiconductor and electronics manufacturers. The total purchase price of the acquisition was $182.2 million . We incurred $3.3 million in transactional costs during the thirteen week period ended December 31, 2015, which were recorded in selling, general and administrative costs in our consolidated statements of operations. The excess of the purchase price over the fair value of the net assets acquired was $109.2 million , which was recorded as goodwill in the Industry Group and is primarily related to expected future cash flows attributable to the synergies expected to be realized after our acquisition and integration of the acquired electrical fault analysis (“EFA”) business. The preliminary fair values of the assets acquired and liabilities assumed in the acquisition were recognized as follows (in thousands): Purchase Price Allocation Current assets $ 64,335 Non-current assets 9,930 Deferred tax assets 207 Current liabilities (23,859 ) Non-current liabilities (7,889 ) Deferred tax liabilities (1,244 ) Net tangible assets acquired 41,480 Intangible assets acquired: Developed technology 10,500 In-process research and development 13,100 Customer relationships 6,900 Backlog 1,000 Total intangible assets acquired 31,500 Goodwill 109,246 Total $ 182,226 The acquired intangible assets are being amortized using the following methodologies and over the following estimated useful lives: Intangible Asset Amortization Methodology Estimated Useful Life Weighted Average Amortization Period Developed technology Straight-line 2 - 4 years 3.1 years In-process research and development Straight-line 3 years 3.0 years Customer relationships Straight-line 10 years 10.0 years Backlog Amortized when revenue is recognized 0.5 - 1.5 years 0.8 years Total intangible assets 4.5 years The allocation of purchase price consideration to assets and liabilities is not yet finalized. The preliminary allocation of the purchase price was based upon preliminary estimates and assumptions that are subject to change within the measurement period (up to one year from the acquisition date). The primary areas of preliminary purchase price allocation that are not yet finalized are certain tax matters. We are also still in the process of determining how much of the goodwill may be deductible for income tax purposes. In the thirteen week period ended July 3, 2016 , we recorded additional deferred tax liabilities of $1.2 million which also resulted in an increase in goodwill. In the thirteen week period ended July 3, 2016 , the acquired business contributed revenue of $20.7 million and net income of $1.2 million to our consolidated financial results. In the twenty-six week period ended July 3, 2016 , the acquired business contributed revenue of $34.5 million and net loss of $0.5 million to our consolidated financial results. No pro forma financial information has been provided for this acquisition as it is not significant compared to our overall consolidated financial position. Intangible Assets Patents, trademarks and other acquired intangible assets are amortized using the straight-line method over their estimated useful lives ranging from 6 months to 10 years. Customer relationships are amortized using the straight-line method over their estimated useful lives ranging from 5 to 10 years. Developed technology is amortized using the straight-line method over the estimated useful life of the related technology ranging from 2 to 10 years. In-process research and development costs are amortized using the straight-line method over their estimated useful lives ranging from 3 to 5.5 years. The gross amount of our acquired intangible assets and the related accumulated amortization was as follows (in thousands): July 3, December 31, Patents, trademarks and other $ 25,865 $ 24,278 Accumulated amortization (16,436 ) (13,923 ) Net patents, trademarks and other 9,429 10,355 Customer relationships 28,565 21,245 Accumulated amortization (9,944 ) (8,083 ) Net customer relationships 18,621 13,162 Developed technology 33,093 22,155 Accumulated amortization (14,118 ) (10,517 ) Net developed technology 18,975 11,638 In-process research and development 15,806 2,669 Accumulated amortization (2,054 ) (1,881 ) Net in-process research and development 13,752 788 Total intangible assets, net $ 60,777 $ 35,943 Amortization expense was as follows (in thousands): Twenty-Six Weeks Ended July 3, June 28, Patents, trademarks and other $ 2,292 $ 1,904 Customer relationships 1,701 1,332 Developed technology 3,434 1,753 In-process research and development 153 136 Total amortization expense $ 7,580 $ 5,125 Expected amortization, without consideration for foreign currency effects, is as follows over the next five years and thereafter (in thousands): Patents, Trademarks and Other Customer Relationships Developed Technology In-Process Research and Development Total Remainder of 2016 $ 1,106 $ 1,716 $ 3,513 $ 153 $ 6,488 2017 2,918 3,086 5,543 2,682 14,229 2018 2,133 3,002 2,910 4,367 12,412 2019 2,033 2,609 2,910 4,367 11,919 2020 1,215 2,295 1,535 2,183 7,228 Thereafter 24 5,913 2,564 — 8,501 Total future amortization expense $ 9,429 $ 18,621 $ 18,975 $ 13,752 $ 60,777

Product Warranties Disclosures [Abstract]
Warranty Reserves	WARRANTY RESERVES Our products generally carry a one-year warranty. A reserve is established at the time of sale to cover estimated warranty costs and certain commitments for product upgrades as a component of cost of sales on our consolidated statements of operations. Our estimate of warranty cost is primarily based on our history of warranty repairs and maintenance, as applied to systems currently under warranty. For our new products without a history of known warranty costs, we estimate the expected costs based on our experience with similar product lines and technology. While most new products are extensions of existing technology, the estimate could change if new products require a significantly different level of repair and maintenance than similar products have required in the past. Our estimated warranty costs are reviewed and updated on a quarterly basis. Changes to the reserve occur as volume, product mix and warranty costs fluctuate. The following is a summary of warranty reserve activity (in thousands): Twenty-Six Weeks Ended July 3, June 28, Balance, beginning of period $ 14,107 $ 13,005 Reductions for warranty costs incurred (7,023 ) (7,234 ) Warranties issued 8,427 7,809 Translation and changes in estimates 285 (269 ) Balance, end of period $ 15,796 $ 13,311

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our Chief Executive Officer. We are organized based on a group structure, which we categorize as the Industry Group and the Science Group . The following tables summarize various financial amounts for each of our business segments (in thousands): Thirteen Weeks Ended Twenty-Six Weeks Ended July 3, June 28, July 3, June 28, Sales to External Customers: Industry Group $ 123,167 $ 119,580 $ 245,118 $ 231,480 Science Group 136,198 104,609 242,891 213,525 Total $ 259,365 $ 224,189 $ 488,009 $ 445,005 Gross Profit: Industry Group $ 65,070 $ 64,747 $ 125,329 $ 121,357 Science Group 61,375 47,358 108,388 96,019 Total $ 126,445 $ 112,105 $ 233,717 $ 217,376 July 3, December 31, Goodwill: Industry Group $ 170,647 $ 60,360 Science Group 86,634 85,247 Total $ 257,281 $ 145,607 Total Assets: Industry Group $ 598,995 $ 516,397 Science Group 442,339 488,096 Corporate and Eliminations 391,660 345,356 Total $ 1,432,994 $ 1,349,849 Market segment disclosures are presented to the gross profit level as this is the primary performance measure for which the segment general managers are responsible. Selling, general and administrative, research and development and other operating expenses are managed and reported at the corporate level and, because these costs are not directly tied to any individual market segment, they have not been allocated to the market segments. See the consolidated statements of operations for reconciliations from gross profit to income before income taxes. These reconciling items are not included in the measure of profit and loss for each reportable segment. In the thirteen week periods ended July 3, 2016 and June 28, 2015 , our top 10 customers accounted for approximately 30% and 38% of our total annual net revenue, respectively. In the twenty-six week periods ended July 3, 2016 and June 28, 2015 , our top 10 customers accounted for approximately 29% and 33% of our total annual net revenue, respectively.

Restructuring and Related Activities [Abstract]
Restructuring, Reorganization, Relocation and Severance	RESTRUCTURING AND REORGANIZATION Second Quarter 2014 Realignment During the second quarter of 2014, we implemented a resource realignment plan (the “Realignment Plan”) aimed at improving our operational efficiency by eliminating redundancies in sites and personnel resulting from recent acquisitions and expansion activities. We also shifted our resources to growing regions, such as Asia, and potential growth markets, such as structural biology, oil and gas, near-line semiconductor processing and metals research, in order to better position us to pursue our growth strategy. The Realignment Plan activities included the consolidation of our three Australia sites in Canberra; the closure of our facility in Delmont, Pennsylvania and relocation of those operations to our new facility in the Czech Republic; relocation of our Japan demonstration facility to our Shanghai facility; selective reductions in staffing, relocations and compensation adjustments related to the foregoing activities and other realignment of management resources. The Realignment Plan was completed at the end of 2014 and we do not expect to incur any additional costs under this plan. The following table summarizes our restructuring and reorganization expenditures (in thousands): Thirteen Weeks Ended Twenty-Six Weeks Ended July 3, June 28, July 3, June 28, Restructuring and reorganization $ — $ (21 ) $ (102 ) $ (142 ) Total $ — $ (21 ) $ (102 ) $ (142 ) Restructuring and Reorganization Accrual The following table summarizes the charges, expenditures, write-offs and adjustments related to our restructuring and reorganization accrual (in thousands): Twenty-Six Weeks Ended Realignment Plan July 3, June 28, Beginning accrued liability $ 655 $ 9,161 Charged to expense, net (102 ) (142 ) Expenditures (145 ) (6,750 ) Write-offs and adjustments 24 (577 ) Ending accrued liability $ 432 $ 1,692

Fair Value Disclosures [Abstract]
Fair Value Measurements of Assets and Liabilities	FAIR VALUE MEASUREMENTS OF ASSETS AND LIABILITIES Factors used in determining the fair value of our financial assets and liabilities are summarized into three broad categories: • Level 1 – quoted prices in active markets for identical securities as of the reporting date; • Level 2 – other significant directly or indirectly observable inputs, including quoted prices for similar securities, interest rates, prepayment speeds and credit risk; and • Level 3 – significant inputs that are generally less observable than objective sources, including our own assumptions in determining fair value. The factors or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Following are the disclosures related to the fair value of our financial assets and (liabilities) (in thousands): July 3, 2016 Level 1 Level 2 Level 3 Total Trading securities: Equity securities – mutual funds $ 9,221 $ — $ — $ 9,221 Derivative contracts, net — 1,962 — 1,962 Total $ 9,221 $ 1,962 $ — $ 11,183 December 31, 2015 Level 1 Level 2 Level 3 Total Trading securities: Equity securities – mutual funds $ 8,677 $ — $ — $ 8,677 Derivative contracts, net — 1,013 — 1,013 Total $ 8,677 $ 1,013 $ — $ 9,690 We use an income approach to value the assets and liabilities for outstanding derivative contracts using current market information as of the reporting date, such as spot rates, interest rate differentials and implied volatility. There were no transfers between fair value categories or changes to our valuation techniques during the twenty-six week periods ended July 3, 2016 . We believe the carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and other current liabilities are a reasonable approximation of the fair value of those financial instruments because of the nature of the underlying transactions and the short-term maturities involved.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS In the normal course of business, we are exposed to foreign currency risk and we use derivatives to mitigate financial exposure from movements in foreign currency exchange rates. The aggregate notional amount of outstanding derivative contracts were as follows (in thousands): July 3, December 31, Cash flow hedges $ 120,000 $ 150,000 Balance sheet hedges 213,727 195,653 Total outstanding derivative contracts $ 333,727 $ 345,653 The outstanding contracts at July 3, 2016 have varying maturities through the fourth quarter of 2017 . We do not enter into derivative financial instruments for speculative purposes. We attempt to mitigate derivative credit risk by transacting with highly rated counterparties. We have evaluated the credit and nonperformance risks associated with our derivative counterparties and believe them to be insignificant and not warranting a credit adjustment at July 3, 2016 . In addition, there are no credit contingent features in our derivative instruments. Balance Sheet Related In countries outside of the U.S., we transact business in U.S. dollars and in various other currencies. We attempt to mitigate our currency exposures for recorded transactions by using forward exchange contracts to reduce the risk that our future cash flows will be adversely affected by changes in exchange rates. We enter into forward sale or purchase contracts for foreign currencies to economically hedge specific cash, receivables or payables positions denominated in foreign currencies. Changes in fair value of derivatives entered into to mitigate the foreign exchange risks related to these balance sheet items are recorded in other income (expense) together with the transaction gain or loss from the respective balance sheet position as follows (in thousands): Thirteen Weeks Ended Twenty-Six Weeks Ended July 3, June 28, July 3, June 28, Foreign currency loss, inclusive of the impact of derivatives $ (662 ) $ (486 ) $ (1,438 ) $ (606 ) Cash Flow Hedges We use zero cost and net purchased collar contracts and option contracts to hedge certain anticipated foreign currency exchange transactions. The foreign exchange hedging structure may extend, generally, up to a twenty-four month time horizon. The hedging transactions we undertake primarily limit our exposure to changes in the U.S. dollar/euro and the U.S. dollar/Czech koruna exchange rates. The hedges are designed to protect us as the U.S. dollar weakens, but also provide us with some flexibility if the dollar strengthens. These derivatives meet the criteria to be designated as cash flow hedges and, accordingly, we record the change in fair value of the effective portion of these hedge contracts relating to anticipated transactions in other comprehensive income rather than net income until the underlying hedged transaction affects net income. Gains and losses resulting from the ineffective portion of the hedge contracts, if any, are recognized as a component of net income. Gains and losses related to cash flow derivative contracts not designated as hedging instruments are recorded as a component of net income. Summary Our derivative instruments are subject to master netting arrangements and are presented net in our balance sheet. We do not have any financial collateral related to these netting arrangements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation Policy	The consolidated financial statements include the accounts of FEI Company and our wholly-owned subsidiaries (collectively, “FEI”). All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates Policy	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period.
Restricted Cash Policy	As part of our contracts with certain customers, we are required to provide letters of credit or bank guarantees which these customers can draw against in the event we do not perform in accordance with our contractual obligations. Bank guarantees and letters of credit outstanding as of July 3, 2016 were approximately $39.7 million . Restricted cash balances securing bank guarantees that expire within 12 months of the balance sheet date are recorded as a current asset on our consolidated balance sheets. Restricted cash balances securing bank guarantees that expire beyond 12 months from the balance sheet date are recorded as long-term restricted cash on our consolidated balance sheets.
Inventories Policy	Inventories are stated at the lower of cost or market, with cost determined by standard cost methods, which approximate the first-in, first-out method. Inventory costs include material, labor and manufacturing overhead. Service inventories that exceed the estimated requirements for the next 12 months based on recent usage levels are reported as a long-term asset. Management has established inventory reserves based on estimates of excess and/or obsolete current and non-current inventory.
Intangible Assets Policy	Patents, trademarks and other acquired intangible assets are amortized using the straight-line method over their estimated useful lives ranging from 6 months to 10 years. Customer relationships are amortized using the straight-line method over their estimated useful lives ranging from 5 to 10 years. Developed technology is amortized using the straight-line method over the estimated useful life of the related technology ranging from 2 to 10 years. In-process research and development costs are amortized using the straight-line method over their estimated useful lives ranging from 3 to 5.5 years.
Warranty Liabilities Policy	Our products generally carry a one-year warranty. A reserve is established at the time of sale to cover estimated warranty costs and certain commitments for product upgrades as a component of cost of sales on our consolidated statements of operations. Our estimate of warranty cost is primarily based on our history of warranty repairs and maintenance, as applied to systems currently under warranty. For our new products without a history of known warranty costs, we estimate the expected costs based on our experience with similar product lines and technology. While most new products are extensions of existing technology, the estimate could change if new products require a significantly different level of repair and maintenance than similar products have required in the past. Our estimated warranty costs are reviewed and updated on a quarterly basis. Changes to the reserve occur as volume, product mix and warranty costs fluctuate.
