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 report our revenue based on a group structure organization, which we categorize as the Industry Group and the Science Group . Our products include transmission electron microscopes (“TEMs”); scanning electron microscopes (“SEMs”); DualBeam TM systems which combine a SEM and a focused ion beam system (“FIB”) on a single platform; stand-alone FIBs; high-performance optical microscopes, pore-scale micro computed tomography (“microCT”) equipment, three-dimensional modeling software, and service and components to support these products. TEMs provide the highest resolution images of samples and their internal structure, down to the atomic level. SEMs provide detailed images of the surface and shape of samples. Optical microscopes provide a wider field of view than SEMs and TEMs. DualBeams and FIBs image, manipulate, mill and deposit material for a variety of purposes, including preparation of samples for TEMs. Substantially all of these product categories are sold into all of our markets. Individual models of our products are increasingly designed to provide specific solutions and applications in each of our markets. Our DualBeam systems include models that have wafer handling capability and are purchased by semiconductor equipment manufacturers (“wafer-level DualBeam systems”) and models that have small stages and are sold to customers in several markets (“small-stage DualBeam systems”). 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 and twenty-six week periods ended June 28, 2015 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, 2014 , which was filed with the Securities and Exchange Commission (“SEC”) on February 23, 2015 . 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, reorganization, relocation and severance 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. Reclassifications Certain reclassifications to prior year consolidated financial statements have been made to conform to current period presentation. These reclassifications had no effect on our consolidated statements of operations.

Goodwill and Other Intangible Assets	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill The roll-forward of activity related to our goodwill was as follows (in thousands): Twenty-Six Weeks Ended June 28, June 29, Balance, beginning of period $ 170,773 $ 136,152 Goodwill additions 4,100 46,880 Goodwill adjustments (6,937 ) 1,962 Balance, end of period $ 167,936 $ 184,994 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 Eisenberg Bros Ltd. On January 9, 2015 we acquired certain assets and liabilities of Eisenberg Bros Ltd. ("EB"), which previously operated as our exclusive agent in Israel of FEI products and services. The total purchase price of the acquisition was $5.4 million . We paid $0.2 million in transaction costs, which were expensed as incurred and are recorded in selling, general and administrative costs in our consolidated statements of operations. The total purchase price was allocated to the net tangible and intangible assets acquired based on their preliminary fair values as of January 9, 2015 . The fair value of net tangible liabilities assumed was $0.1 million and the fair value of net intangible assets acquired was $1.4 million , which consisted solely of customer relationships. The acquired customer relationships will be amortized over a period of 5 years. The excess of the purchase price over the fair value of the net assets acquired was $4.1 million , which was recorded as goodwill in the Industry Group and is primarily related to expected future cash flows from synergies arising from the establishment of a sales and service workforce in Israel. No pro forma financial information has been provided for this acquisition as it is not material. Acquisition of Lithicon AS On February 5, 2014 we acquired 100% of the outstanding shares of Lithicon AS (“Lithicon”), which has operations in Norway and Australia. Lithicon provides digital rock technology services and pore-scale micro computed tomography (“microCT”) equipment to oil and gas companies. In conjunction with the acquisition we have obtained the helical scan microCT product and associated software from the Australian National University through a licensing and development agreement. The total purchase price of the acquisition was $68.0 million , plus an adjustment for the change in final closing accounts of $0.4 million . We paid $0.4 million in transaction costs. Those costs were expensed as incurred and are recorded in selling, general and administrative costs in our consolidated statements of operations. The total purchase price was allocated to the net tangible and intangible assets acquired based on their preliminary fair values as of February 5, 2014. The fair value of net tangible liabilities assumed was $7.7 million and the fair value of net intangible assets acquired was $22.0 million , which consisted of $18.6 million in developed technology, $2.2 million of customer relationships and $1.2 million of purchased backlog. Including an increase to net deferred tax liabilities of $8.1 million , the excess of the purchase price over the fair value of the net assets acquired was $46.9 million , which was recorded as goodwill in the Industry Group. The goodwill arising from the acquisition of Lithicon is primarily related to expected future cash flows from expansion of our product offerings in the oil and gas market to include digital rock services, as well as synergies from the introduction of the microCT product to the existing FEI product suite. The acquired developed technology, customer relationships and purchased backlog will be amortized over a period of 10 years, 5 years and 2 years, respectively. Other Intangible Assets Patents, trademarks and other acquired intangible assets are amortized using the straight-line method over their estimated useful lives of 2 to 10 years. Customer relationships are amortized using the straight-line method over their estimated useful lives of 5 to 10 years. Developed technology is amortized using the straight-line method over the estimated useful life of the related technology, which ranges from 5.5 to 10 years.

Warranty Reserves

Warranty Reserves	6 Months Ended
	Jun. 28, 2015
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 June 28, June 29, Balance, beginning of period $ 13,005 $ 12,705 Reductions for warranty costs incurred (7,234 ) (6,430 ) Warranties issued 7,809 6,347 Translation and changes in estimates (269 ) (2 ) Balance, end of period $ 13,311 $ 12,620

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our tax provision for the thirteen and twenty-six week periods ended June 28, 2015 consisted primarily of taxes accrued in the U.S. and foreign jurisdictions. We continue to record a valuation allowance against a portion of our U.S. and foreign deferred tax assets as we do not believe it is more likely than not that we will be able to utilize the deferred tax assets in future periods. Deferred Income Taxes Net deferred tax assets were classified on the balance sheet as follows (in thousands): June 28, December 31, Deferred tax assets – current $ 9,587 $ 8,225 Deferred tax assets – non-current 8,927 6,605 Deferred tax liabilities – current (480 ) (218 ) Deferred tax liabilities – non-current (7,666 ) (9,576 ) Net deferred tax assets $ 10,368 $ 5,036 Valuation allowance $ 3,287 $ 4,350 Unrecognized Tax Benefits During the twenty-six week periods ended June 28, 2015 and June 29, 2014 , unrecognized tax benefits, interest and penalties decreased by $0.5 million and $0.6 million , respectively, primarily due to the recognition of benefits relating to tax credits and transfer pricing positions, offset by accruals for interest and penalties and uncertainty surrounding foreign net operating losses and domestic manufacturing deductions. We recognize interest and penalties related to unrecognized tax benefits in tax expense. For our major tax jurisdictions, the following years were open for examination by the tax authorities as of June 28, 2015 : Jurisdiction Open Tax Years U.S. 2011 and forward The Netherlands 2011 and forward Czech Republic 2012 and forward

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 currently report our segments based on a group structure organization. Our segments are Industry Group and Science Group . The following tables summarize various financial amounts for each of our business segments (in thousands): Thirteen Weeks Ended Twenty-Six Weeks Ended June 28, June 29, June 28, June 29, Sales to External Customers: Industry Group $ 119,580 $ 127,225 $ 231,480 $ 233,664 Science Group 104,609 109,730 213,525 229,556 Total $ 224,189 $ 236,955 $ 445,005 $ 463,220 Gross Profit: Industry Group $ 64,747 $ 64,088 $ 121,357 $ 120,221 Science Group 47,358 45,763 96,019 95,955 Total $ 112,105 $ 109,851 $ 217,376 $ 216,176 June 28, December 31, Goodwill: Industry Group $ 78,695 $ 76,858 Science Group 89,241 93,915 Total $ 167,936 $ 170,773 Total Assets: Industry Group $ 472,350 $ 444,168 Science Group 407,726 470,899 Corporate and Eliminations 520,327 502,751 Total $ 1,400,403 $ 1,417,818 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 June 28, 2015 and June 29, 2014 , our top 10 customers accounted for approximately 38.1% and 36.9% of our total annual net revenue, respectively. In the twenty-six week periods ended June 28, 2015 and June 29, 2014 , our top 10 customers accounted for approximately 33.1% and 31.9% of our total annual net revenue, respectively. No single customer accounted for more than 10% of net revenues during the thirteen and twenty-six week periods ended June 28, 2015 and June 29, 2014 .

Restructuring and Related Activities [Abstract]
Restructuring, Reorganization, Relocation and Severance	RESTRUCTURING, REORGANIZATION, RELOCATION AND SEVERANCE Second Quarter 2014 Realignment During the second quarter of 2014, we implemented a resource 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. This 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 the costs incurred under our second quarter realignment plan: Thirteen Weeks Ended Twenty-Six Weeks Ended Realignment Costs June 28, June 29, June 28, June 29, Inventory write-offs $ — $ 755 $ — $ 755 Acceleration of acquisition-related earn-out — 2,500 — 2,500 Impairment and other asset write-offs — 466 — 466 Restructuring activities (21 ) 2,228 (142 ) 2,228 Total $ (21 ) $ 5,949 $ (142 ) $ 5,949 These costs have been recorded in our consolidated statements of operations as follows: Thirteen Weeks Ended Twenty-Six Weeks Ended Statement of Operations Classification June 28, June 29, June 28, June 29, Cost of sales $ — $ 755 $ — $ 755 Selling, general and administrative — 2,966 — 2,966 Restructuring, reorganization and relocation (21 ) 2,228 (142 ) 2,228 Total $ (21 ) $ 5,949 $ (142 ) $ 5,949 First Quarter 2014 Restructuring During the first quarter of 2014, we engaged in a restructuring plan principally aimed at consolidating our sales force in Europe. The $1.3 million cost incurred in implementing the restructuring plan primarily consisted of severance and other employee termination related costs, and was incurred during the first quarter of 2014. We do not expect to incur any additional costs under this plan.

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): June 28, 2015 Level 1 Level 2 Level 3 Total Available for sale marketable securities: U.S. Government-backed securities $ 27,596 $ — $ — $ 27,596 Agency bonds — 56,605 — 56,605 Commercial paper — — — — Certificates of deposit — 19,763 — 19,763 Municipal bonds — 10,625 — 10,625 Corporate bonds — 10,730 — 10,730 Trading securities: Equity securities – mutual funds 8,296 — — 8,296 Derivative contracts, net — 2,775 — 2,775 Total $ 35,892 $ 100,498 $ — $ 136,390 December 31, 2014 Level 1 Level 2 Level 3 Total Available for sale marketable securities: U.S. treasury notes $ 17,608 $ — $ — $ 17,608 Agency bonds — 51,951 — 51,951 Commercial paper — 13,500 — 13,500 Certificates of deposit — 19,122 — 19,122 Municipal bonds — 27,119 — 27,119 Corporate bonds — 10,902 — 10,902 Trading securities: Equity securities – mutual funds 7,351 — — 7,351 Derivative contracts, net — (2,739 ) — (2,739 ) Total $ 24,959 $ 119,855 $ — $ 144,814 Agency bonds are securities backed by U.S. government-sponsored entities. U.S. Government-backed securities include Treasury Bills and Treasury Notes. 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 period ended June 28, 2015 . 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): June 28, December 31, Cash flow hedges $ 142,000 $ 222,000 Balance sheet hedges 152,726 153,499 Total outstanding derivative contracts $ 294,726 $ 375,499 The outstanding contracts at June 28, 2015 have varying maturities through the second quarter of 2016 . 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 June 28, 2015 . 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 June 28, June 29, June 28, June 29, Foreign currency loss, inclusive of the impact of derivatives $ (486 ) $ (723 ) $ (606 ) $ (953 ) 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 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. The effect of these netting arrangements on our balance sheet is as follows (in thousands): Offsetting of Derivative Assets Offsetting of Derivative Liabilities June 28, 2015 Gross Amounts of Recognized Assets Gross Amounts Offset in the Balance Sheet Net Amounts Presented in Other Current Assets Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Balance Sheet Net Amounts Presented in Other Current Liabilities Foreign exchange contracts designated as hedging instruments $ 1,249 $ (251 ) $ 998 $ — $ — $ — Foreign exchange contracts not designated as hedging instruments 2,593 (349 ) 2,244 590 (123 ) 467 Total $ 3,842 $ (600 ) $ 3,242 $ 590 $ (123 ) $ 467 Offsetting of Derivative Assets Offsetting of Derivative Liabilities December 31, 2014 Gross Amounts of Recognized Assets Gross Amounts Offset in the Balance Sheet Net Amounts Presented in Other Current Assets Gross Amounts of Recognized Liabilities Gross Amounts Offset in the Balance Sheet Net Amounts Presented in Other Current Liabilities Foreign exchange contracts designated as hedging instruments $ — $ — $ — $ 3,283 $ (865 ) $ 2,418 Foreign exchange contracts not designated as hedging instruments 2,456 (670 ) 1,786 4,729 (2,622 ) 2,107 Total $ 2,456 $ (670 ) $ 1,786 $ 8,012 $ (3,487 ) $ 4,525 The effect of derivative instruments was as follows (in thousands): Thirteen Weeks Ended Twenty-Six Weeks Ended Foreign Exchange Contracts in Cash Flow Hedging Relationships June 28, June 29, June 28, June 29, Amount of gain/(loss): Recognized in AOCI (effective portion) $ (5,436 ) $ (2,057 ) $ (13,724 ) $ (4,259 ) Reclassified from AOCI into revenue (effective portion) — 9 (112 ) 46 Reclassified from AOCI into cost of sales (effective portion) (3,084 ) (1,096 ) (5,647 ) (1,666 ) Recognized in Other, net (ineffective portion and amount excluded from effectiveness testing) (15 ) (9 ) (108 ) (9 ) Foreign Exchange Contracts Not in Cash Flow Hedging Relationships Amount of gain/(loss): Recognized in Other, net $ 1,473 $ (636 ) $ (5,685 ) $ (3,745 ) The unrealized losses at June 28, 2015 are expected to be reclassified to net income during the next twelve months as a result of the underlying hedged transactions also being recorded in net income.

New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS ASU 2014-09 On May 28, 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. On July 9, 2015, the FASB voted to defer the effective date of the ASU for one year. 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 ASU 2014-09 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.

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. 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
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. Significant accounting policies and estimates underlying the accompanying consolidated financial statements include:
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 June 28, 2015 were approximately $47.1 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 of 2 to 10 years. Customer relationships are amortized using the straight-line method over their estimated useful lives of 5 to 10 years. Developed technology is amortized using the straight-line method over the estimated useful life of the related technology, which ranges from 5.5 to 10 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.
