Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	General The accompanying consolidated financial statements for the three and six month periods ended June 30, 2018 and July 1, 2017 , have been prepared by Darling Ingredients Inc., a Delaware corporation (“Darling”, and together with its subsidiaries, the “Company”) in accordance with generally accepted accounting principles in the United States (“GAAP”) without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The information furnished herein reflects all adjustments (consisting only of normal recurring accruals) that are, in the opinion of management, necessary to present a fair statement of the financial position and operating results of the Company as of and for the respective periods. However, these operating results are not necessarily indicative of the results expected for a full fiscal year. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been omitted pursuant to such rules and regulations. However, management of the Company believes, to the best of their knowledge, that the disclosures herein are adequate to make the information presented not misleading. The accompanying consolidated financial statements should be read in conjunction with the audited consolidated financial statements contained in the Company’s Form 10-K for the fiscal year ended December 30, 2017 .

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies (a) Basis of Presentation The consolidated financial statements include the accounts of Darling and its consolidated subsidiaries. Noncontrolling interests represent the outstanding ownership interest in the Company's consolidated subsidiaries that are not owned by the Company. In the accompanying Consolidated Statements of Operations, the noncontrolling interest in net income of the consolidated subsidiaries is shown as an allocation of the Company's net income and is presented separately as “Net income attributable to noncontrolling interests.” In the Company's Consolidated Balance Sheets, noncontrolling interests represent the ownership interests in the Company consolidated subsidiaries' net assets held by parties other than the Company. These ownership interests are presented separately as “Noncontrolling interests” within “Stockholders' Equity.” All significant intercompany balances and transactions have been eliminated in consolidation. (b) Fiscal Periods The Company has a 52 / 53 week fiscal year ending on the Saturday nearest December 31 . Fiscal periods for the consolidated financial statements included herein are as of June 30, 2018 , and include the 13 and 26 weeks ended June 30, 2018 , and the 13 and 26 weeks ended July 1, 2017 . (c) Cash, Cash Equivalents and Restricted Cash The Company considers all short-term highly liquid instruments, with an original maturity of three months or less, to be cash equivalents. Cash balances are recorded net of book overdrafts when a bank right-of-offset exists. All other book overdrafts are recorded in accounts payable and the change in the related balance is reflected in operating activities on the Consolidated Statement of Cash Flows. In addition, the Company has bank overdrafts, which are considered a form of short-term financing with changes in the related balance reflected in financing activities in the Consolidated Statement of Cash Flows. In November 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ( “ ASU ” ) No. 2016-18, Restricted Cash. This ASU amends Topic 230, Statement of Cash Flows , which includes new guidance on the classification and presentation of restricted cash in the statement of cash flows in order to eliminate the discrepancies that currently exist in how companies present these changes. This ASU requires restricted cash to be included with cash and cash equivalents when explaining the changes in cash in the statement of cash flows. The Company adopted this on December 31, 2017 and it did not have a material impact on the Company's consolidated financial statements. Restricted cash represents amounts required to be set aside to cover self-insurance claims and collateral for environmental claims. The following table provides a reconciliation of cash, cash equivalents and restricted cash on the consolidated balance sheet that sum to the total of the same amounts shown in the consolidated statement of cash flows (in thousands): June 30, 2018 December 30, 2017 Cash and cash equivalents $ 104,120 $ 106,774 Restricted cash 142 142 Total cash, cash equivalents and restricted cash shown in the consolidated statements of cash flow $ 104,262 $ 106,916 (d) Accounts Receivable and Allowance for Doubtful Accounts The Company maintains allowances for doubtful accounts for estimated losses resulting from customers’ non-payment of trade accounts receivable owed to the Company. These trade receivables arise in the ordinary course of business from sales of raw material, finished product or services to the Company’s customers. The estimate of allowance for doubtful accounts is based upon the Company’s bad debt experience, prevailing market conditions, and aging of trade accounts receivable, among other factors. If the financial condition of the Company’s customers deteriorates, resulting in the customers’ inability to pay the Company’s receivables as they come due, additional allowances for doubtful accounts may be required. The Company has entered into agreements with third party banks to factor certain of the Company's trade receivables in order to enhance working capital by turning trade receivables into cash faster. Under these agreements, the Company will sell certain selected customers trade receivables to the third party banks without recourse for cash less a nominal fee. For the three and six months ended June 30, 2018, the Company sold approximately $ 31.8 million and $ 50.6 million of its trade receivables and incurred approximately $ 0.1 million and $ 0.2 million in fees, which are recorded as interest expense, respectively. For the three and six months ended July 1, 2017, no receivables were factored. (e) Revenue Recognition The Company recognizes revenue on sales when control of the promised finished product is transferred to the Company's customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for the finished product. Service revenues are recognized when the service occurs. Certain customers may be required to prepay prior to shipment in order to maintain payment protection related to certain foreign and domestic sales. These amounts are recorded as unearned revenue and recognized when control of the promised finished product is transferred to the Company's customer. See Note 19 to the consolidated financial statements. (f) Foreign Currency Translation and Remeasurement Foreign currency translation is included as a component of accumulated other comprehensive loss and reflects the adjustments resulting from translating the foreign currency denominated financial statements of foreign subsidiaries into U.S. dollars. The functional currency of the Company's foreign subsidiaries is the currency of the primary economic environment in which the entity operates, which is generally the local currency of the country. Accordingly, assets and liabilities of the foreign subsidiaries are translated into U.S. dollars at fiscal period end exchange rates, including intercompany foreign currency transactions that are of long-term investment nature. Income and expense items are translated at average exchange rates occurring during the period. Changes in exchange rates that affect cash flows and the related receivables or payables are recognized as transaction gains and losses in determining net income. The Company incurred net foreign currency translation losses of approximately $ 60.0 million for the six months ended June 30, 2018 and net foreign currency translation gains of approximately $ 67.7 million for the six months ended July 1, 2017 , respectively. (g) Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. In the consolidated statements of operations, previously reported amounts have been adjusted to reflect the correction of an immaterial classification error in net sales and cost of sales as disclosed in Company’s Form 10-K for the fiscal year ended December 30, 2017 . In addition, previous reported net periodic pension costs have been reclassified in the consolidated statements of operations to conform to current year presentation, as described in Note 13 and previously reported amounts in the consolidated statements of cash flows have been adjusted to reflect the adoption of the presentation of restricted cash. (h) Earnings/(loss) Per Share Basic income/(loss) per common share is computed by dividing net income attributable to Darling by the weighted average number of common shares including non-vested and restricted shares outstanding during the period. Diluted income per common share is computed by dividing net income attributable to Darling by the weighted average number of common shares outstanding during the period increased by dilutive common equivalent shares determined using the treasury stock method. Net Income/(loss) per Common Share (in thousands, except per share data) Three Months Ended June 30, 2018 July 1, 2017 Loss Shares Per Share Income Shares Per Share Basic: Net Income/(loss) attributable to Darling $ (30,420 ) 164,651 $ (0.18 ) $ 9,149 164,718 $ 0.06 Diluted: Effect of dilutive securities: Add: Option shares in the money and dilutive effect of non-vested stock awards — 4,166 Less: Pro forma treasury shares — (2,053 ) Diluted: Net income/(loss) attributable to Darling $ (30,420 ) 164,651 $ (0.18 ) $ 9,149 166,831 $ 0.05 Net Income per Common Share (in thousands, except per share data) Six Months Ended June 30, 2018 July 1, 2017 Income Shares Per Share Income Shares Per Share Basic: Net Income attributable to Darling $ 66,885 164,774 $ 0.41 $ 14,978 164,728 $ 0.09 Diluted: Effect of dilutive securities: Add: Option shares in the money and dilutive effect of non-vested stock awards 2,536 3,089 Less: Pro forma treasury shares (1,051 ) (1,469 ) Diluted: Net income attributable to Darling $ 66,885 166,259 $ 0.40 $ 14,978 166,348 $ 0.09 For the three months ended June 30, 2018 and July 1, 2017 , respectively, 3,801,665 and 772,402 outstanding stock options were excluded from diluted income per common share as the effect was antidilutive. For the three months ended June 30, 2018 and July 1, 2017 , respectively, 2,634,828 and 680,100 shares of non-vested stock and stock equivalents were excluded from diluted income per common share as the effect was antidilutive. For the six months ended June 30, 2018 and July 1, 2017 , respectively, 2,275,607 and 791,116 outstanding stock options were excluded from diluted income per common share as the effect was antidilutive. For the three months ended June 30, 2018 and July 1, 2017 , respectively, 1,475,394 and 853,313 shares of non-vested stock and stock equivalents were excluded from diluted income per common share as the effect was antidilutive.

Acquisitions and Dispositions	Acquisitions and Dispositions In May 2018, the Company acquired substantially all of the assets of Kruger Commodities, Inc. (the “Kruger Acquisition”) including protein conversion facilities in Hamilton, MI and Tama, IA, along with a protein blending operation and used cooking oil collection business in Omaha, NE. The Company paid approximately $ 51.1 million in cash for assets and assumed liabilities consisting of property, plant and equipment of approximately $ 15.2 million , intangible assets of approximately $ 15.9 million , consisting of routes, permits and non-compete agreements, goodwill of approximately $ 19.6 million , and other of approximately $ 0.4 million . The amounts have been recorded on a preliminary basis pending working capital finalization that is expected to occur within the next 6 months. The Company does not expect a material change from the working capital finalization. The identifiable intangible assets have a weighted average life of 15 years. In May 2018, the Company sold its Terra Renewal Services (“TRS”) industrial residuals business to American Residuals Group, LLC. TRS is a provider of environmental services focused on the collection, hauling, and disposal of non-hazardous, liquid and semi-solid waste streams from the food processing industry. All of the used cooking oil business originally acquired as part of TRS was retained by the Company. The transaction price for the industrial residuals business sold was $ 80.0 million in cash and resulted in the Company recording a loss on the TRS sale of approximately $ 15.5 million , due to a substantial portion of the original purchase price of TRS being allocated to the industrial residuals business. In January 2018, the Company through a wholly-owned international subsidiary, sold a portion of its interest in a majority owned consolidated subsidiary for approximately $ 2.8 million . This transaction resulted in the foreign subsidiary being deconsolidated and accounted for using the equity method of accounting, effective January 2018.

Income Taxes

Income Taxes	6 Months Ended
	Jun. 30, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company has provided income taxes for the three and six month periods ended June 30, 2018 and July 1, 2017 , based on its estimate of the effective tax rate for the entire 2018 and 2017 fiscal years. The Company’s estimated annual effective tax rate is based on forecasts of income by jurisdiction, permanent differences between book and tax income, the relative proportion of income and losses by jurisdiction, and statutory income tax rates. Discrete events such as the assessment of the ultimate outcome of tax audits, audit settlements, recognizing previously unrecognized tax benefits due to the lapsing of statutes of limitation, recognizing or derecognizing deferred tax assets due to projections of income or loss and changes in tax laws are recognized in the period in which they occur. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company expects to have access to its offshore earnings with no material U.S. tax impact. Therefore, the Company does not consider earnings from its foreign subsidiaries to be permanently reinvested offshore. The Company periodically assesses whether it is more likely than not that it will generate sufficient taxable income to realize its deferred income tax assets. In making this determination, the Company considers all available positive and negative evidence and makes certain assumptions. The Company considers, among other things, its deferred tax liabilities, the overall business environment, its historical earnings and losses, current industry trends and its outlook for future years. Unrecognized tax benefits represent the difference between tax positions taken or expected to be taken in a tax return and the benefits recognized for financial statement purposes. As of June 30, 2018 , the Company had $ 2.2 million of gross unrecognized tax benefits and $ 1.2 million of related accrued interest and penalties. It is reasonably possible within the next twelve months that the Company’s gross unrecognized tax benefits may decrease by up to $ 1.9 million , excluding interest and penalties, primarily due to potential settlements and expiration of certain statutes of limitations. On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act” or “U.S. tax reform”) was signed into law, effective January 1, 2018, that, among other things, lowered the corporate income tax rate from 35% to 21% , moved the country towards a territorial tax system with a one-time mandatory tax on previously deferred earnings of foreign subsidiaries, and introduced new provisions regarding the taxation of Global Intangible Low-Taxed Income (“GILTI”) of foreign subsidiaries. The Company is subject to the GILTI provisions beginning January 1, 2018. The FASB allows companies to adopt an accounting policy to either recognize deferred taxes for GILTI or treat such as a tax cost in the year incurred. The Company’s accounting policy election is to account for GILTI as incurred. The Company has reasonably estimated GILTI with no material impact to the estimated annual effective tax rate. Accounting Standards Codification 740, Accounting for Income Taxes, requires companies to recognize the effects of changes in tax laws and tax rates on deferred tax assets and liabilities in the period in which the new legislation is enacted. Due to the timing of the Tax Act and the substantial changes it brings, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (SAB 118), which provides registrants a measurement period to report the impact of the new U.S. tax law. During the measurement period, provisional amounts for the effects of the tax law are recorded to the extent a reasonable estimate can be made. To the extent that all information necessary is not available, prepared or analyzed, companies may recognize provisional estimated amounts for a period of up to one year following enactment of the Tax Act. As a result of U.S. Tax Reform, the Company recorded a provisional tax benefit at December 30, 2017 of $ 12.1 million related to the mandatory deemed repatriation including an adjustment to the U.S. deferred tax liability associated with foreign earnings that were not permanently reinvested outside the U.S. and $ 62.9 million for the re-measurement of deferred taxes at the reduced 21% federal tax rate. The Company recorded provisional amounts for the mandatory repatriation including its impact on the Company’s deferred taxes because certain information related to the computation of earnings and profits is not readily available and there is limited information from federal and state taxing authorities regarding the application and interpretation of the recently enacted legislation. The Company revised its 2017 provisional estimates under SAB No. 118 and recorded a provisional tax benefit of $ 1.6 million during the three months ended June 30, 2018 due to additional guidance by the Internal Revenue Service (IRS) and the continued refinement of the Company's mandatory repatriation including refinements of earnings and profits calculations and the impact of the Company's deferred taxes. The amounts recorded through June 30, 2018 are provisional and the Company is continuing to gather information and is waiting on further guidance from the IRS and other standard-setting bodies on the Tax Act. The Company’s major taxing jurisdictions include the United States (federal and state), Canada, the Netherlands, Belgium, Brazil, Germany, France and China. The Company is subject to regular examination by various tax authorities and although the final outcome of these examinations is not yet determinable, the Company does not anticipate that any of the examinations will have a significant impact on the Company's results of operations or financial position. The statute of limitations for the Company’s major tax jurisdictions is open for varying periods, but is generally closed through the 2010 tax year.

Equity [Abstract]
Other Comprehensive Income	Other Comprehensive Income/(Loss) The Company follows FASB authoritative guidance for reporting and presentation of comprehensive income and its components. Other comprehensive income (loss) is derived from adjustments that reflect pension adjustments, natural gas swap adjustments, corn option adjustments and foreign currency translation adjustments. In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU amends Topic 220, Income Statement - Reporting Comprehensive Income , which will allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The ASU is effective for fiscal years beginning after December 15, 2018; however, the Company elected to early adopt ASU No. 2018-02 during the quarter ended March 31, 2018. The adoption resulted in a $ 4.8 million reclassification from accumulated other comprehensive income (loss) to retained earnings resulting from the Tax Cuts and Jobs Act.

Equity [Abstract]
Stockholders' Equity	Stockholders' Equity Fiscal 2018 Long-Term Incentive Opportunity Awards (2018 LTIP) . On January 29, 2018, the Compensation Committee (the “Committee”) of the Company's Board of Directors adopted the 2018 LTIP pursuant to which they awarded certain of the Company's key employees, 637,115 stock options and 295,514 performance share units (the “PSUs”) under the Company's 2017 Omnibus Incentive Plan. The stock options vest 33.33% on the first, second and third anniversaries of the grant date. The PSUs are tied to a three -year forward-looking performance period and will be earned based on the Company's average return on capital employed (ROCE), as calculated in accordance with the terms of the award agreement, relative to the average ROCE of the Company's performance peer group companies, with the earned award to be determined in the first quarter of fiscal 2021, after the final results for the relevant performance period are determined. The PSUs were granted at a target of 100% , but each PSU will reduce or increase depending on the Company's ROCE relative to that of the performance peer group companies and is also subject to the application of a total shareholder return (TSR) cap/collar modifier depending on the Company's TSR during the performance period relative to that of the performance peer group companies. On August 7, 2017, the Company's Board of Directors, approved the extension for an additional two years of its previously announced share repurchase program of up to an aggregate of $ 100.0 million of the Company's common stock depending on market conditions. As of June 30, 2018 , the Company has approximately $ 100.0 million remaining under the share repurchase program approved in August 2017.

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans The Company has retirement and pension plans covering a substantial number of its domestic and foreign employees. Most retirement benefits are provided by the Company under separate final-pay noncontributory and contributory defined benefit and defined contribution plans for all salaried and hourly employees (excluding those covered by union-sponsored plans) who meet service and age requirements. Although various defined benefit formulas exist for employees, generally these are based on length of service and earnings patterns during employment. Effective January 1, 2012, the Company's Board of Directors authorized the Company to proceed with the restructuring of its domestic retirement benefit program to include the closing of Darling's salaried and hourly defined benefit plans to new participants as well as the freezing of service and wage accruals thereunder effective December 31, 2011 (a curtailment of these plans for financial reporting purposes) and the enhancing of benefits under the Company's domestic defined contribution plans. The Company-sponsored domestic hourly union plan has not been curtailed; however, several locations of the Company-sponsored domestic hourly union plan have been curtailed as a result of collective bargaining renewals for those sites. In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU amends Topic 715, Compensation - Retirement Benefits , which requires that an employer report the service cost component of net benefit costs to be disaggregated from all other components and reported in the same line item or items as other compensation costs. The other components of net benefit cost are required to be presented in the income statement separately from the service cost. The Company adopted this ASU effective December 31, 2017. The Company used the practical expedient to retrospectively present the prior year amounts. The components of net period pension cost other than the service cost component are included in the line item “Other expense, net” in the Company's Consolidated Statements of Operations. Net pension cost for the three and six months ended June 30, 2018 and July 1, 2017 includes the following components (in thousands): Pension Benefits Pension Benefits Three Months Ended Six Months Ended June 30, July 1, June 30, July 1, Service cost $ 779 $ 750 $ 1,578 $ 1,485 Interest cost 1,616 1,679 3,241 3,348 Expected return on plan assets (2,059 ) (1,790 ) (4,123 ) (3,578 ) Amortization of prior service cost 8 9 17 18 Amortization of net loss 888 1,203 1,776 2,406 Net pension cost $ 1,232 $ 1,851 $ 2,489 $ 3,679 The Company's funding policy for employee benefit pension plans is to contribute annually not less than the minimum amount required nor more than the maximum amount that can be deducted for federal and foreign income tax purposes. Contributions are intended to provide not only for benefits attributed to service to date, but also for those expected to be earned in the future. Based on actuarial estimates at June 30, 2018 , the Company expects to contribute approximately $ 4.8 million to its pension plans to meet funding requirements during the next twelve months. Additionally, the Company has made tax deductible discretionary and required contributions to its pension plans for the six months ended June 30, 2018 and July 1, 2017 of approximately $ 1.5 million and $ 1.6 million , respectively. The Company participates in various multiemployer pension plans which provide defined benefits to certain employees covered by labor contracts. These plans are not administered by the Company and contributions are determined in accordance with provisions of negotiated labor contracts to meet their pension benefit obligations to their participants. The Company's contributions to each multiemployer plan represent less than 5% of the total contributions to each such plan. Based on the most currently available information, the Company has determined that, if a withdrawal were to occur, withdrawal liabilities on two of the plans in which the Company currently participates could be material to the Company, with one of these material plans certified as critical or red zone. With respect to the other multiemployer pension plans in which the Company participates and which are not individually significant, six plans have certified as critical or red zone, one plan has certified as endangered or yellow zone as defined by the Pension Protection Act of 2006. The Company has received notices of withdrawal liability from two U.S. multiemployer plans in which it participated. As of June 30, 2018 , the Company has an aggregate accrued liability of approximately $ 1.7 million representing the present value of scheduled withdrawal liability payments under these multiemployer plans. While the Company has no ability to calculate a possible current liability for under-funded multiemployer plans that could terminate or could require additional funding under the Pension Protection Act of 2006, the amounts could be material.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company’s operations are exposed to market risks relating to commodity prices that affect the Company’s cost of raw materials, finished product prices and energy costs and the risk of changes in interest rates and foreign currency exchange rates. The Company makes limited use of derivative instruments to manage cash flow risks related to natural gas usage, diesel fuel usage, inventory, forecasted sales and foreign currency exchange rates. The Company does not use derivative instruments for trading purposes. Natural gas swaps and options are entered into with the intent of managing the overall cost of natural gas usage by reducing the potential impact of seasonal weather demands on natural gas that increases natural gas prices. Heating oil swaps and options are entered into with the intent of managing the overall cost of diesel fuel usage by reducing the potential impact of seasonal weather demands on diesel fuel that increases diesel fuel prices. Soybean meal options are entered into with the intent of managing the impact of changing prices for poultry meal sales. Corn options and future contracts are entered into with the intent of managing U.S. forecasted sales of bakery by-products (“BBP”) by reducing the impact of changing prices. Foreign currency forward contracts are entered into to mitigate the foreign exchange rate risk for transactions designated in a currency other than the local functional currency. At June 30, 2018 , the Company had corn option contracts and soybean meal option contracts outstanding that qualified and were designated for hedge accounting as well as corn option and forward contracts, foreign currency forward contracts that did not qualify and were not designated for hedge accounting. Entities are required to report all derivative instruments in the statement of financial position at fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, on the reason for holding the instrument. If certain conditions are met, entities may elect to designate a derivative instrument as a hedge of exposures to changes in fair value, cash flows or foreign currencies. If the hedged exposure is a cash flow exposure, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of other comprehensive income (outside of earnings) and is subsequently reclassified into earnings when the forecasted transaction affects earnings. Any amounts excluded from the assessment of hedge effectiveness, as well as the ineffective portion of the gain or loss, are reported in earnings immediately. If the derivative instrument is not designated as a hedge, the gain or loss is recognized in earnings in the period of change. Cash Flow Hedges In the first six months of fiscal 2018, the Company entered into soybean meal option contracts that are considered cash flow hedges. Under the terms of the soybean meal option contracts, the Company hedged a portion of its forecasted poultry meal sales into the fourth quarter of fiscal 2018. As of June 30, 2018 , some of the contracts have been settled while the remaining contract positions and activity are not significant to the Company. At June 30, 2018 and December 30, 2017, the aggregate fair value of these soybean meal option contracts was approximately $ 0.7 million and zero , respectively. The June 30, 2018 amounts are included in other current assets on the balance sheet, with an offset recorded in accumulated other comprehensive income for the effective portion. In fiscal 2017 and the first six months of fiscal 2018 , the Company entered into corn option contracts on the Chicago Board of Trade that are designated as cash flow hedges. Under the terms of the corn option contracts, the Company hedged a portion of its U.S. forecasted sales of BBP into the fourth quarter of fiscal 2018. As of June 30, 2018 , some of the contracts have been settled while the remaining contract positions and activity are not significant to the Company. At June 30, 2018 and December 30, 2017, the aggregate fair value of these corn option contracts was approximately $ 1.4 million and $ 3.4 million , respectively. These amounts are included in other current assets on the balance sheet, with an offset recorded in accumulated other comprehensive income for the effective portion. From time to time, the Company may enter into corn option contracts in the future. As of June 30, 2018 , the Company had the following outstanding forward contract amounts that were entered into to hedge the future payments of intercompany note transactions, foreign currency transactions in currencies other than the functional currency and forecasted transactions in currencies other than the functional currency. All of these transactions are currently not designated for hedge accounting (in thousands): Functional Currency Contract Currency Type Amount Type Amount Brazilian real 32,387 Euro 7,490 Brazilian real 80,599 U.S. dollar 22,460 Euro 90,399 U.S. dollar 107,009 Euro 14,184 Polish zloty 61,280 Euro 7,153 Japanese yen 926,570 Euro 85,702 Chinese renminbi 650,727 Euro 12,592 Australian dollar 19,350 Euro 4,827 British pound 4,262 Polish zloty 24,712 Euro 5,685 British pound 88 Euro 100 British pound 139 U.S. dollar 105 Japanese yen 254,613 U.S. dollar 2,322 The Company estimates the amount that will be reclassified from accumulated other comprehensive gain at June 30, 2018 into earnings over the next 12 months will be approximately $ 0.7 million . As of June 30, 2018 , no amounts have been reclassified into earnings as a result of the discontinuance of cash flow hedges. The table below summarizes the effect of derivatives not designated as hedges on the Company's consolidated statements of operations for the three and six months ended June 30, 2018 and July 1, 2017 (in thousands): Loss or (Gain) Recognized in Income on Derivatives Not Designated as Hedges Three Months Ended Six Months Ended Derivatives not designated as hedging instruments Location June 30, 2018 July 1, 2017 June 30, 2018 July 1, 2017 Foreign Exchange Foreign currency loss/(gain) $ (3,481 ) $ 6,130 $ (1,827 ) $ 9,276 Foreign Exchange Selling, general and administrative expense 2,506 492 2,995 (989 ) Corn options and futures Net sales 763 (18 ) 454 (40 ) Corn options and futures Cost of sales and operating expenses (818 ) 46 (306 ) 316 Soybean Meal Net sales — (9 ) — (281 ) Soybean Oil Net sales — — — 45 Total $ (1,030 ) $ 6,641 $ 1,316 $ 8,327 At June 30, 2018 , the Company had forward purchase agreements in place for purchases of approximately $ 14.2 million of natural gas and diesel fuel. These forward purchase agreements have no net settlement provisions and the Company intends to take physical delivery of the underlying product. Accordingly, the forward purchase agreements are not subject to the requirements of fair value accounting because they qualify and the Company has elected to account for these as normal purchases as defined in the FASB authoritative guidance.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements FASB authoritative guidance defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The following table presents the Company’s financial instruments that are measured at fair value on a recurring and nonrecurring basis as of June 30, 2018 and are categorized using the fair value hierarchy under FASB authoritative guidance. The fair value hierarchy has three levels based on the reliability of the inputs used to determine the fair value.

See Note 14 (Derivatives) for discussion on the Company's derivatives. The carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximates fair value due to the short maturity of these instruments and as such have been excluded from the table above. The carrying amount of the Company's other debt is not deemed to be significantly different from the fair value and all other instruments have been recorded at fair value. The fair value of the senior notes, term loan A, term loan B and revolver debt is based on market quotation from third-party banks.

Contingencies

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies The Company is a party to various lawsuits, claims and loss contingencies arising in the ordinary course of its business, including insured worker's compensation, auto, and general liability claims, assertions by certain regulatory and governmental agencies related to permitting requirements and/or air, wastewater and storm water discharges from the Company’s processing facilities, litigation involving tort, contract, statutory, labor, employment, and other claims, and tax matters. The Company’s workers compensation, auto and general liability policies contain significant deductibles or self-insured retentions. The Company estimates and accrues its expected ultimate claim costs related to accidents occurring during each fiscal year under these insurance policies and carries this accrual as a reserve until these claims are paid by the Company. As a result of the matters discussed above, the Company has established loss reserves for insurance, environmental, litigation and tax contingencies. At June 30, 2018 and December 30, 2017 , the reserves for insurance, environmental, litigation and tax contingencies reflected on the balance sheet in accrued expenses and other non-current liabilities were approximately $ 62.6 million and $ 61.4 million , respectively. The Company has insurance recovery receivables of approximately $ 25.0 million as of June 30, 2018 and December 30, 2017 , related to the insurance contingencies. The Company's management believes these reserves for contingencies are reasonable and sufficient based upon present governmental regulations and information currently available to management; however, there can be no assurance that final costs related to these contingencies will not exceed current estimates. The Company believes that the likelihood is remote that any additional liability from the lawsuits and claims that may not be covered by insurance would have a material effect on the Company's financial position, results of operations or cash flows. Lower Passaic River Area . In December 2009 , the Company, along with numerous other entities, received notice from the United States Environmental Protection Agency (“EPA”) that the Company (as alleged successor-in-interest to The Standard Tallow Corporation) is considered a potentially responsible party (a “PRP”) with respect to alleged contamination in the lower 17 -mile area of the Passaic River which is part of the Diamond Alkali Superfund Site located in Newark, New Jersey. The Company’s designation as a PRP is based upon the operation of former plant sites located in Newark and Kearny, New Jersey by The Standard Tallow Corporation, an entity that the Company acquired in 1996. In the letter, EPA requested that the Company join a group of other parties in funding a remedial investigation and feasibility study at the site. As of the date of this report, the Company has not agreed to participate in the funding group. In March 2016, the Company received another letter from EPA notifying the Company that it had issued a Record of Decision selecting a remedy for the lower 8.3 miles of the lower Passaic River area at an estimated cost of $ 1.38 billion . The EPA letter makes no demand on the Company and lays out a framework for remedial design/remedial action implementation in which the EPA will first seek funding from major PRPs. The letter indicates that the EPA has sent the letter to over 100 parties, which include large chemical and refining companies, manufacturing companies, foundries, plastic companies, pharmaceutical companies and food and consumer product companies. The EPA has already offered early cash out settlements to 20 of the other PRPs and has stated that other parties who did not discharge dioxins, furans or polychlorinated biphenyls (which are considered the contaminants of primary concern) may also be eligible for cash out settlements and has begun a settlement analysis using a third-party allocator. The Company is participating in this allocation process as it asserts that it is not responsible for any liabilities of its former subsidiary The Standard Tallow Corporation, which was legally dissolved in 2000, and that, in any event, The Standard Tallow Corporation did not discharge dioxins, furans or polychlorinated biphenyls and is therefore not a major PRP. On September 30, 2016, Occidental Chemical Corporation (“OCC”) entered into an agreement with the EPA to perform the remedial design for the cleanup plan for the lower 8.3 miles of the Passaic River. On June 30, 2018, OCC filed a complaint in the United States District Court for the District of New Jersey against over 100 companies, including the Company, seeking cost recovery or contribution for costs under the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”) relating to various investigations and cleanups OCC has conducted or is conducting in connection with the Passaic River. According to the complaint, OCC has incurred or is incurring costs which include the estimated cost to complete the remedial design for the cleanup plan for the lower 8.3 miles of the Passaic River. OCC is also seeking a declaratory judgment to hold the defendants liable for their proper shares of future response costs, including the remedial action for the lower 8.3 miles of the Passaic River. The Company, along with 40 of the other defendants, had previously received a release from OCC of its CERCLA contribution claim of $ 165 million associated with the costs to design the remedy for the lower 8.3 miles of the Passaic River. The Company's ultimate liability, if any, for investigatory costs, remedial costs and/or natural resource damages in connection with the lower Passaic River area cannot be determined at this time; however, as of the date of this report, the Company has found no evidence that the former Standard Tallow Corporation plant sites contributed any of the primary contaminants of concern to the Passaic River and, therefore, there is nothing that leads the Company to believe that this matter will have a material effect on the Company's financial position, results of operations or cash flows. Fresno Facility Permit Issue. The Company has been named as a defendant and a real party in interest in a lawsuit filed on April 9, 2012 in the Superior Court of the State of California, Fresno County, styled Concerned Citizens of West Fresno vs. Darling International Inc. The complaint, as subsequently amended, alleges that the Company's Fresno facility is operating without a proper use permit and seeks, among other things, injunctive relief. The complaint had at one time also alleged that the Company's Fresno facility constitutes a continuing private and public nuisance, but the plaintiff has since amended the complaint to drop these allegations. The City of Fresno was also named as a defendant in the original complaint but has since had a judgment entered in its favor and is no longer a defendant in the lawsuit; however, in December 2013 the City of Fresno filed a motion to intervene as a plaintiff in this matter. The Superior Court heard the motion on February 4, 2014, and entered an order on February 18, 2014 denying the motion. Rendering operations have been conducted on the site since 1955, and the Company believes that it possesses all of the required federal, state and local permits to continue to operate the facility in the manner currently conducted and that its operations do not constitute a private or public nuisance. Accordingly, the Company intends to defend itself vigorously in this matter. Discovery has begun and this matter was scheduled for trial in July 2014; however, the parties have agreed to stay the litigation while they participate in a mediation process, which remains ongoing. In January 2017, the Company entered into a non-binding letter of intent with the City of Fresno pursuant to which the City and the Company will work toward the execution of a definitive agreement to relocate the facility to a different location in Fresno. Whether an agreement to relocate the facility ultimately gets executed is subject to the Company’s receipt of certain incentives and an agreement by the Concerned Citizens of West Fresno to settle and dismiss the aforementioned litigation. While management cannot predict the ultimate outcome of this matter, management does not believe the outcome will have a material effect on the Company's financial condition, results of operations or cash flows.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue On December 31, 2017, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), using the modified retrospective basis. Results for reporting periods beginning December 31, 2017 are presented under Topic 606, while prior periods are not adjusted and continue to be reported in accordance with the Company's historic accounting under Topic 605. The adoption did not change the timing of revenue recognition as the Company's revenues have been determined to be recognized at a point in time and not over time. The Company elected not to capitalize contract fulfillment costs as the recovery of such costs are for a period of less than one year's time and are not material to the Company. At June 30, 2018, there were no contract assets recorded on the Consolidated Balance sheets. Also, the Company elected to treat shipping and handling as fulfillment costs under Topic 606, which will result in billed freight recorded in cost of sales and netted against freight costs. Sales, value-add, and other taxes collected concurrently with revenue-producing activities are excluded from revenue and booked on a net basis. The Company extends payment terms to its customers based on commercially acceptable practices. The term between invoicing and payment due date is not significant. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring finished products or performing services, which is generally based on executed agreement or purchase order. Most of the Company's products are shipped based on the customer specifications. Customer returns are infrequent and not material to the Company. Adjustments to net sales for sales deductions are generally recognized in the same period as the sale or when known. Customers in certain industries or countries may be required to prepay prior to shipment in order to maintain payment protection. These represent short-term prepayment from customers and are not material to the Company. The following table summarizes the impact of adopting Topic 606 on the Company's consolidated financial statements for the three and six months ended June 30, 2018 (in thousands): Impact of changes in accounting policies As reported Adjustments Balances without adoption of Topic 606 Three Months Ended June 30, 2018 Net sales $ 846,646 45,449 $ 892,095 Cost of sales and operating expenses $ 653,001 45,449 $ 698,450 Six Months Ended June 30, 2018 Net sales $ 1,722,020 91,636 $ 1,813,656 Cost of sales and operating expenses $ 1,331,100 91,636 $ 1,422,736 The following tables presents the Company revenues disaggregated by geographic area and major product types by reportable segment for the three and six months ended June 30, 2018 and July 1, 2017 (in thousands): Three Months Ended June 30, 2018 Feed Ingredients Food Ingredients Fuel Ingredients Total Geographic Area North America $ 408,402 $ 45,988 $ 10,512 $ 464,902 Europe 82,324 159,622 60,582 302,528 China 6,402 45,481 — 51,883 South America — 9,916 — 9,916 Other 1,695 15,722 — 17,417 Net sales $ 498,823 $ 276,729 $ 71,094 $ 846,646 Major product types Fats $ 137,143 $ 38,815 $ — $ 175,958 Used cooking oil 48,084 — — 48,084 Proteins 221,467 — — 221,467 Bakery 44,482 — — 44,482 Other rendering 28,979 — — 28,979 Food ingredients — 217,366 — 217,366 Bioenergy — — 60,582 60,582 Biofuels — — 10,512 10,512 Other 18,668 20,548 — 39,216 Net sales $ 498,823 $ 276,729 $ 71,094 $ 846,646 Six Months Ended June 30, 2018 Feed Ingredients Food Ingredients Fuel Ingredients Total Geographic Area North America $ 798,778 $ 90,265 $ 32,052 $ 921,095 Europe 170,114 343,261 123,098 636,473 China 12,080 89,393 — 101,473 South America — 24,260 — 24,260 Other 3,649 35,070 — 38,719 Net sales $ 984,621 $ 582,249 $ 155,150 $ 1,722,020 Major product types Fats $ 280,695 $ 83,634 $ — $ 364,329 Used cooking oil 84,692 — — 84,692 Proteins 424,862 — — 424,862 Bakery 91,233 — — 91,233 Other rendering 60,341 — — 60,341 Food ingredients — 451,289 — 451,289 Bioenergy — — 123,098 123,098 Biofuels — — 32,052 32,052 Other 42,798 47,326 — 90,124 Net sales $ 984,621 $ 582,249 $ 155,150 $ 1,722,020 Three Months Ended July 1, 2017 (a) Feed Ingredients Food Ingredients Fuel Ingredients Total Geographic Area Revenues North America $ 415,465 $ 48,838 $ 10,866 $ 475,169 Europe 124,925 157,209 56,536 338,670 China 7,210 41,223 — 48,433 South America — 12,107 — 12,107 Other 1,519 19,032 — 20,551 Net sales $ 549,119 $ 278,409 $ 67,402 $ 894,930 Major product types Fats $ 160,235 $ 43,567 $ — $ 203,802 Used cooking oil 45,457 — — 45,457 Proteins 195,750 — — 195,750 Bakery 51,591 — — 51,591 Other rendering 73,555 — — 73,555 Food ingredients — 212,128 — 212,128 Bioenergy — — 56,536 56,536 Biofuels — — 10,866 10,866 Other 22,531 22,714 — 45,245 Net sales $ 549,119 $ 278,409 $ 67,402 $ 894,930 Six Months Ended July 1, 2017 (b) Feed Ingredients Food Ingredients Fuel Ingredients Total Geographic Area Revenues North America $ 838,400 $ 94,563 $ 18,949 $ 951,912 Europe 247,852 306,910 108,113 662,875 China 11,944 82,883 — 94,827 South America — 25,081 — 25,081 Other 3,547 35,198 — 38,745 Net sales $ 1,101,743 $ 544,635 $ 127,062 $ 1,773,440 Major product types Fats $ 318,240 $ 84,460 $ — $ 402,700 Used cooking oil 89,503 — — 89,503 Proteins 393,901 — — 393,901 Bakery 107,688 — — 107,688 Other rendering 147,155 — — 147,155 Food ingredients — 418,407 — 418,407 Bioenergy — — 108,113 108,113 Biofuels — — 18,949 18,949 Other 45,256 41,768 — 87,024 Net sales $ 1,101,743 $ 544,635 $ 127,062 $ 1,773,440 (a) As noted above prior year amounts have not been adjusted under the modified retrospective method for billed freight of approximately $ 37.9 million that is included in net sales in the three months ended July 1, 2017 .

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Raw Material Agreement The Company entered into a Raw Material Agreement with the DGD Joint Venture in May 2011 pursuant to which the Company will offer to supply certain animal fats and used cooking oil at market prices, up to the DGD Joint Venture's full operational requirement of feedstock, but the DGD Joint Venture is not obligated to purchase the raw material offered by the Company. Additionally, the Company may offer other feedstocks to the DGD Joint Venture, such as inedible corn oil, purchased on a resale basis. For the three months ended June 30, 2018 and July 1, 2017 , the Company has recorded sales to the DGD Joint Venture of approximately $ 33.8 million and $ 42.5 million , respectively. For the six months ended June 30, 2018 and July 1, 2017 , the Company has recorded sales to the DGD Joint Venture of approximately $ 66.9 million and $ 78.1 million , respectively. At June 30, 2018 and December 30, 2017 , the Company has $ 1.5 million and $ 5.6 million in outstanding receivables due from the DGD Joint Venture, respectively. In addition, the Company has eliminated approximately $ 5.6 million of additional sales for the three months ended June 30, 2018 to defer the Company's portion of profit of approximately $ 1.2 million on those sales relating to inventory assets remaining on the DGD Joint Venture's balance sheet at June 30, 2018 . Revolving Loan Agreement On February 23, 2015, Darling through its wholly owned subsidiary Darling Green Energy LLC, (“Darling Green”) and a third party Diamond Alternative Energy, LLC (“Diamond Alternative” and together with Darling Green, the “DGD Lenders”) entered into a revolving loan agreement (the “DGD Loan Agreement”) with the DGD Joint Venture Opco. The DGD Lenders have committed to making loans available to Opco in the total amount of $ 10.0 million with each lender committed to $ 5.0 million of the total commitment. Any borrowings by Opco under the DGD Loan Agreement are at the applicable annum rate equal to the sum of (a) the LIBO Rate (meaning Reuters BBA Libor Rates Page 3750) on such day plus (b) 2.50% . The DGD Loan Agreement matures on December 31, 2018, unless extended by agreement of the parties. As of June 30, 2018 , no amounts are owed to Darling Green under the DGD Loan Agreement.

New Accounting Pronoucements [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvement to Accounting for Hedging Activities. This ASU amends Topic 815, Derivatives and Hedging , which is intended to more closely align hedge accounting with companies' risk management strategies and simplify the application of hedge accounting. The guidance includes certain targeted improvements to ease the operational burden of applying hedge accounting. The ASU is effective for fiscal years beginning after December 15, 2018 and for interim periods therein with early adoption permitted. The Company will be required to apply the guidance on a cumulative-effect basis with adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company is currently evaluating the impact of this standard. In January 2017, the FASB issued ASU No. 2017-04 Simplifying the Test for Goodwill Impairment. This ASU amends Topic 350, Intangibles-Goodwill and Other , which will simplify the goodwill impairment calculation by eliminating Step 2 from the current goodwill impairment test. Under the new guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The ASU eliminates existing guidance that requires an entity to determine goodwill impairment by calculating the implied fair value of goodwill by hypothetically assigning the fair value of a reporting unit to all of the assets and liabilities as if that reporting unit had been acquired in a business combination. This ASU is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The initial adoption of this ASU is not expected to have a material impact on the Company's consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Under the new ASU, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (1) a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and (2) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance lessor accounting is largely unchanged. The new lease guidance simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. This ASU is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. However, in January 2018, the FASB has proposed a change that if approved will allow entities to elect a simplified transition approach whereby they would apply the provisions of the new guidance at the effective date without adjusting the comparative periods presented. The Company has begun the implementation of a new software to manage its leases and is in the process of identification and entry of leases into the new software. The Company is assessing the impact of this new standard, specifically on its consolidated balance sheets and disclosures, and does not expect adoption to significantly change the recognition, measurement or presentation of lease expense within the consolidated statements of operations or cash flows.

Summary of Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of Darling and its consolidated subsidiaries. Noncontrolling interests represent the outstanding ownership interest in the Company's consolidated subsidiaries that are not owned by the Company. In the accompanying Consolidated Statements of Operations, the noncontrolling interest in net income of the consolidated subsidiaries is shown as an allocation of the Company's net income and is presented separately as “Net income attributable to noncontrolling interests.” In the Company's Consolidated Balance Sheets, noncontrolling interests represent the ownership interests in the Company consolidated subsidiaries' net assets held by parties other than the Company. These ownership interests are presented separately as “Noncontrolling interests” within “Stockholders' Equity.” All significant intercompany balances and transactions have been eliminated in consolidation.
Fiscal Periods	Fiscal Periods The Company has a 52 / 53 week fiscal year ending on the Saturday nearest December 31 . Fiscal periods for the consolidated financial statements included herein are as of June 30, 2018 , and include the 13 and 26 weeks ended June 30, 2018 , and the 13 and 26 weeks ended July 1, 2017 .
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash The Company considers all short-term highly liquid instruments, with an original maturity of three months or less, to be cash equivalents. Cash balances are recorded net of book overdrafts when a bank right-of-offset exists. All other book overdrafts are recorded in accounts payable and the change in the related balance is reflected in operating activities on the Consolidated Statement of Cash Flows. In addition, the Company has bank overdrafts, which are considered a form of short-term financing with changes in the related balance reflected in financing activities in the Consolidated Statement of Cash Flows.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts The Company maintains allowances for doubtful accounts for estimated losses resulting from customers’ non-payment of trade accounts receivable owed to the Company. These trade receivables arise in the ordinary course of business from sales of raw material, finished product or services to the Company’s customers. The estimate of allowance for doubtful accounts is based upon the Company’s bad debt experience, prevailing market conditions, and aging of trade accounts receivable, among other factors. If the financial condition of the Company’s customers deteriorates, resulting in the customers’ inability to pay the Company’s receivables as they come due, additional allowances for doubtful accounts may be required.
Revenue Recognition	Revenue Recognition The Company recognizes revenue on sales when control of the promised finished product is transferred to the Company's customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for the finished product. Service revenues are recognized when the service occurs. Certain customers may be required to prepay prior to shipment in order to maintain payment protection related to certain foreign and domestic sales. These amounts are recorded as unearned revenue and recognized when control of the promised finished product is transferred to the Company's customer.
Income Taxes	The Company has provided income taxes for the three and six month periods ended June 30, 2018 and July 1, 2017 , based on its estimate of the effective tax rate for the entire 2018 and 2017 fiscal years. The Company’s estimated annual effective tax rate is based on forecasts of income by jurisdiction, permanent differences between book and tax income, the relative proportion of income and losses by jurisdiction, and statutory income tax rates. Discrete events such as the assessment of the ultimate outcome of tax audits, audit settlements, recognizing previously unrecognized tax benefits due to the lapsing of statutes of limitation, recognizing or derecognizing deferred tax assets due to projections of income or loss and changes in tax laws are recognized in the period in which they occur. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company expects to have access to its offshore earnings with no material U.S. tax impact. Therefore, the Company does not consider earnings from its foreign subsidiaries to be permanently reinvested offshore. The Company periodically assesses whether it is more likely than not that it will generate sufficient taxable income to realize its deferred income tax assets. In making this determination, the Company considers all available positive and negative evidence and makes certain assumptions. The Company considers, among other things, its deferred tax liabilities, the overall business environment, its historical earnings and losses, current industry trends and its outlook for future years.
Foreign Currency Translation and Remeasurement	Foreign Currency Translation and Remeasurement Foreign currency translation is included as a component of accumulated other comprehensive loss and reflects the adjustments resulting from translating the foreign currency denominated financial statements of foreign subsidiaries into U.S. dollars. The functional currency of the Company's foreign subsidiaries is the currency of the primary economic environment in which the entity operates, which is generally the local currency of the country. Accordingly, assets and liabilities of the foreign subsidiaries are translated into U.S. dollars at fiscal period end exchange rates, including intercompany foreign currency transactions that are of long-term investment nature. Income and expense items are translated at average exchange rates occurring during the period.
