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’s consolidated subsidiaries' net assets held by parties other than the Company. These ownership interests are presented separately as “Noncontrolling interests” within “Stockholders' Equity.” All 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 28, 2025, and include the 13 and 26 weeks ended June 28, 2025, and the 13 and 26 weeks ended June 29, 2024.

(c)    Cash and Cash Equivalents

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. Restricted cash shown on the Consolidated Balance Sheet as of June 28, 2025 and December 28, 2024, primarily represents the current portion of acquisition consideration hold-back amounts that are part of the purchase price set aside in escrow in the Company’s name for possible indemnification claims by the Company, which amounts will be paid to the sellers in the future if no claims arise. Restricted cash included in other long term assets on the Consolidated Balance Sheet as of June 28, 2025 and December 28, 2024, primarily represents the long term acquisition consideration hold-back amounts that are part of the purchase price set aside in escrow in the Company’s name for possible indemnification claims by the Company, which amounts will be paid to the sellers in the future if no claims arise. A reconciliation of cash, cash equivalents, and restricted cash reported
within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statement of Cash flows is as follows (in thousands):

June 28, 2025December 28, 2024
Cash and cash equivalents$94,577 $75,973 
Restricted cash27,502 37,579 
Restricted cash included in other long-term assets96,630 103,755 
Total cash, cash equivalents and restricted cash shown in the statement of cash flows$218,709 $217,307 

(d)    Accounts Receivable Factoring

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 sells certain selected customers’ trade receivables to third-party banks without recourse for cash less a nominal fee. For the three months ended June 28, 2025 and June 29, 2024, the Company sold approximately $129.1 million and $158.2 million of its trade receivables and incurred approximately $1.5 million and $2.3 million in fees, respectively. For the six months ended June 28, 2025 and June 29, 2024, the Company sold approximately $254.6 million and $295.6 million of its trade receivables and incurred approximately $2.9 million and $4.5 million in fees, respectively.

(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 in accrued expenses and recognized when control of the promised finished product is transferred to the Company’s customer.  See Note 19 (Revenue) to the Company’s Consolidated Financial Statements included herein.

(f)    Earnings Per Share

Basic income 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.

(g)    Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

If it is at least reasonably possible that the estimate of the effect on the financial statements of a condition, situation, or set of circumstances that exist at the date of the financial statements will change in the near term due to one or more future confirming events, and the effect of the change would be material to the financial statements, the Company will disclose the nature of the uncertainty and include an indication that it is at least reasonably possible that a change in the estimate will occur in the near term.  If the estimate involves certain loss contingencies, the disclosure will also include an estimate of the probable loss or range of loss or state that an estimate cannot be made.

As a result of the Russia-Ukraine war and the ongoing or emerging conflicts in the Middle East and the current inflationary environment that might be further impacted by tariffs, we have evaluated the potential impact to the Company’s operations and for any indicators of triggering events that could indicate certain of the Company’s assets may be impaired. Through the six months ended June 28, 2025, the Company has not observed any impairments of the Company’s assets or a significant change in their fair value due to the Russia-Ukraine war and the ongoing or emerging conflicts in the Middle East or inflation or the impacts of tariffs.

As of June 28, 2025, under the equity method of accounting, the Company has an investment in the DGD Joint Venture of approximately $2,082.9 million on the consolidated balance sheet. The Company has recorded equity in net income from the DGD Joint Venture of approximately $6.0 million and $44.2 million for the three months ended June 28, 2025 and June 29, 2024, respectively. The Company has recorded equity in net income/(loss) from the DGD Joint Venture of approximately $(24.5) million and $122.6 million for the six months ended June 28, 2025 and June 29, 2024, respectively.

On August 16, 2022, the U.S. government enacted the Inflation Reduction Act ( the “IR Act”). As part of the IR Act, the blenders tax credits of $1.00 per gallon were extended as is until December 31, 2024, a new Sustainable Aviation Fuel (“SAF”) blenders tax credit was introduced effective for 2023 and 2024, and a new Clean Fuels Production Credit (the “CFPC”) was created effective from 2025 through 2027. Under the IR Act, Section 40B, SAF, blended with Jet A and sold on or before December 31, 2024, receives a base credit of $1.25 per gallon plus $0.01 for each percentage point by which the lifecycle greenhouse gas (“GHG”) emissions reduction percentage exceeds 50% up to a maximum supplementary amount of $0.50. Under the CFPC, on-road transportation fuel receives a base credit of up to $1.00 per gallon of renewable diesel (adjusted for inflation each calendar year) multiplied by the fuel's emission reduction percentage as long as it is produced at a qualifying facility and it meets prevailing wage requirements and apprenticeship requirements. Similarly, SAF produced during calendar year 2025 at a qualified facility that meets the apprenticeship and prevailing wage requirements receives a base credit of $1.75 (adjusted for inflation each calendar year) multiplied by the GHG emissions factor for SAF. In contrast to the blenders tax credit, the CFPC requires that
production must take place in the United States. On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted in the U.S. The OBBBA includes significant tax related provisions. With respect to the CFPC, the OBBBA extends the credit for two years through December 31, 2029, reduces the maximum credit rate for SAF to $1.00 per gallon for gallons produced after December 31, 2025, and beginning in 2026 all eligible transportation fuel must be derived exclusively from feedstocks produced or grown in the U.S., Mexico or Canada. Furthermore, on July 21, 2025, the Internal Revenue Service released Notice 2025-37, announcing the 2025 calendar year inflation adjustment factor for several green energy credits added to the Code by the IR Act, including the CFPC. Specifically, the base credit for on-road transportation fuel is increased to $1.06 per gallon (from $1.00 per gallon) and SAF is increased to $1.86 per gallon (from $1.75 per gallon) provided the fuel is produced at a qualified facility meeting the prevailing wage and apprenticeship requirements. These revised base credits, subject to the aforementioned emission reduction percentages, are applicable for on-road transportation fuel and SAF produced and sold in 2025 (i.e., retroactive effective date of January 1, 2025). For the three months ended June 28, 2025 and June 29, 2024, the DGD Joint Venture recorded approximately $140.2 million and $308.2 million of production tax credits and blenders tax credits, respectively. For the six months ended June 28, 2025 and June 29, 2024, the DGD Joint Venture recorded approximately $191.1 million and $639.2 million of production tax credits and blenders tax credits, respectively. The production tax credit and blenders tax credits are recorded as a reduction of cost of sales by the DGD Joint Venture.

In the six months ended June 28, 2025 and June 29, 2024, the Company received approximately $129.5 million and zero in dividend distributions from the DGD Joint Venture, respectively. In the six months ended June 28, 2025 and June 29, 2024, respectively, the Company made approximately $40.2 million and $90.0 million in capital contributions to the DGD Joint Venture. Subsequent to June 28, 2025, the Company made a capital contribution of approximately $57.0 million on June 30, 2025 to the DGD Joint venture.

In addition to the DGD Joint Venture, the Company has investments in other unconsolidated subsidiaries that are insignificant to the Company.

Miropasz Group

On January 31, 2024, a wholly owned international subsidiary of the Company acquired all of the shares of the Miropasz Group (the “Miropasz Acquisition”), a rendering company in Poland that is now in our Feed Ingredients segment, for a cash purchase price of approximately €105.6 million (approximately $114.3 million USD at the exchange rate of €1.0:USD$1.082198 on the closing date). In addition, the Company incurred a liability of approximately €7.0 million (approximately $7.6 million USD at the exchange rate on the closing date) for acquisition consideration hold-back amount that is part of the purchase price set aside in escrow in the Company’s name for possible indemnification claims by the Company, which amounts will be paid to the sellers in the future if no claims arise. The hold-back amount represents a noncash investing activity during the period of acquisition. During the third quarter of fiscal 2024, the Company received approximately $0.2 million from the sellers as a reduction of the purchase price and other immaterial adjustments. The Company recorded assets and liabilities consisting of property, plant and equipment of approximately $21.2 million, identifiable intangibles which includes routes and immaterial land use rights of approximately $34.9 million with a weighted average life of 17 years, other net assets of approximately $2.8 million which includes cash, working capital and net debt, and goodwill of approximately $62.8 million. Goodwill is expected to strengthen the Company’s base Feed Ingredients business and is nondeductible for tax purposes.
Gelnex

On March 31, 2023, the Company acquired all of the shares of Gelnex, a leading global producer of collagen products (the “Gelnex Acquisition”). The Gelnex Acquisition includes a network of five processing facilities in South America and one in the United States. The initial purchase price of approximately $1.2 billion was comprised of an initial cash payment of approximately $1.1 billion, which consisted of a payment of approximately R$4.3 billion Brazilian real (approximately $853.3 million USD at the exchange rate of R$5.08:USD$1.00 on the closing date) and a payment of approximately $243.5 million in USD, subject to various post-closing adjustments in accordance with the stock purchase agreement. In addition, the Company incurred a liability of approximately $104.1 million for acquisition consideration hold-back amount that is part of the purchase price set aside in escrow in the Company’s name for possible indemnification claims by the Company, which amounts will be paid to the sellers in the future if no claims arise. The hold-back amount represents a noncash investing activity during the period of acquisition. The Gelnex Acquisition gives us immediate capacity to serve the growing needs of our collagen customers and the growing gelatin market. The initial purchase price was financed by borrowing all of the Company’s term A-3 facility of $300.0 million and term A-4 facility of $500.0 million, with the remainder coming through revolver borrowings under the Amended Credit Agreement. During the third quarter of fiscal 2023, the Company made a cash payment for working capital purchase price adjustment per the stock purchase agreement of approximately $14.1 million with an offset to goodwill. The Company obtained new information about facts and circumstances that existed at the acquisition date during the first quarter of fiscal 2024 that resulted in measurement period adjustments to increase property, plant and equipment by approximately $13.7 million, decrease intangible assets by approximately $9.5 million, decrease goodwill by approximately $9.1 million, increase deferred tax liabilities by approximately $5.1 million, increase deferred tax assets by approximately $8.1 million and a decrease in other assets and liabilities of approximately $0.1 million.

Senior Secured Credit Facilities. On June 25, 2025, Darling, Darling International Canada Inc. (“Darling Canada”), Darling International NL Holdings B.V. (“Darling NL”) and Darling Ingredients International Holding B.V. (“Darling
Holding”) entered into a Third Amended and Restated Credit Agreement (the “Amended Credit Agreement”), which amended and restated the Company's then existing Second Amended and Restated Credit Agreement dated January 6, 2014 (as amended from time to time, the “Previous Credit Agreement”), with the lenders from time to time party thereto, JPMorgan Chase Bank, N.A., as Administrative Agent and the other agents party thereto. The Amended Credit Agreement refinanced the loans and commitments outstanding under the Previous Credit Agreement and provides for senior secured credit facilities in the aggregate principal amount of $2.9 billion comprised of (i) the Company’s $900.0 million six-year term A facility (partially comprised of $395.0 million of term A-1 facility and $296.3 million of term A-3 Facility which, in each case, were cashlessly rolled from the Previous Credit Agreement) and (ii) the Company’s $2.0 billion five-year revolving credit facility (up to $50.0 million (as such amount may be increased to an amount not exceeding $150.0 million to the extent consented to by the applicable issuing banks) of which will be available for a letter of credit subfacility and up to $50.0 million of which will be available for a swingline sub-facility) (collectively, the “Senior Secured Credit Facilities”). The Amended Credit Agreement also permits Darling and the other borrowers thereunder to incur ancillary facilities provided by any revolving lender party to the Senior Secured Credit Facilities (with certain restrictions). The revolving credit facility will be used for working capital needs, general corporate purposes and other purposes not prohibited by the Amended Credit Agreement.

The interest rate applicable to any borrowings under the revolving credit facility will equal (i) the Canadian Overnight Repo Rate Average (CORRA) for borrowings denominated in Canadian dollars or the adjusted term secured overnight financing rate (SOFR) for U.S. dollar borrowings or the adjusted euro interbank rate (EURIBOR) for euro borrowings or the adjusted daily simple Sterling overnight index average (SONIA) for British pound borrowings, in each case plus 1.50% per annum or (ii) the alternative base rate (ABR) for U.S. dollar borrowings or Canadian prime rate for Canadian dollar borrowings or the adjusted daily simple European short term rate (ESTR) for euro borrowings or the adjusted daily SONIA rate for British pound borrowings, in each case plus 0.50% per annum, and in each case of clauses (i) and (ii), subject to certain step-ups or step-downs based on the Company’s total leverage ratio. The interest rate applicable to any borrowing under the term A facility equals the adjusted term SOFR plus 1.75% per annum or ABR plus 0.75% subject to certain step-ups and step-downs based on the Company’s total leverage ratio with a minimum of 1.50% for SOFR borrowings and a minimum of 0.50% for ABR borrowings.

As of June 28, 2025, the Company had (i) $480.0 million outstanding under the revolver at SOFR plus a margin of 1.50% per annum for a total of 5.8192% per annum, (ii) $900.0 million outstanding under the term A facility at SOFR plus a margin of 1.75% per annum for a total of 6.06920% per annum, (iii) €124.0 million outstanding under the revolving credit facility at EURIBOR plus a margin of 1.50% per annum for a total of 3.389% per annum and (iv) €22.0 million outstanding under the swingline facility of the revolving credit facility at ESTR plus a margin of 0.50% per annum for a total of 2.429% per annum. As of June 28, 2025, the Company had revolving credit facility availability of $1.27 billion, under the Amended Credit Agreement taking into account amounts borrowed, ancillary facilities of $75.9 million and letters of credit issued of $0.6 million. The Company also had foreign bank guarantees of approximately $12.4 million that are not part of the Company’s Amended Credit Agreement at June 28, 2025. In addition, the Company capitalized approximately $7.5 million of deferred loan costs as of June 28, 2025 in connection with the Amended Credit Agreement.

4.5% Senior Notes due 2032. On June 24, 2025, Darling Global Finance B.V. (the “4.5% Issuer”), an indirect, wholly-owned subsidiary of Darling, issued and sold €750.0 million aggregate principal amount of 4.5% Senior Notes due 2032 (the “4.5% Notes”). The 4.5% Notes, which were offered in a private offering, were issued pursuant to a Senior Notes Indenture, dated as of June 24, 2025 (the “4.5% Indenture”), among Darling Global Finance B.V., Darling, the subsidiary guarantors party thereto from time to time, GLAS Trust Company LLC, as trustee, principal paying agent and registrar. The gross proceeds of the offering, together with borrowings under the Company’s revolving credit facility, were used to (i) redeem the Company’s previous 3.625% senior notes and repay or otherwise refinance the Company’s Previous Credit Agreement, and (ii) pay costs, fees and expenses related to the refinancing.

The 4.5% Notes will mature on July 15, 2032. The 4.5% Issuer pays interest on the 4.5% Notes on January 15 and July 15 of each year commencing on January 15, 2026. Interest on the 4.5% Notes accrues at a rate of 4.5% per annum and is payable in cash. The 4.5% Notes are guaranteed by Darling and all of Darling’s restricted subsidiaries (other than any foreign subsidiary or any receivable entity) that are borrowers under or guarantee the Senior Secured Credit Facilities (collectively, the “4.5% Guarantors”). The 4.5% Notes and the guarantees thereof are senior unsecured obligations of the 4.5% Issuer and the 4.5% Guarantors and rank equally in right of payment to all of the 4.5% Issuer's and the 4.5% Guarantors’ existing and future senior indebtedness. The 4.5% Indenture contains covenants limiting Darling’s ability and the ability of its restricted subsidiaries (including the 4.5% Issuer) to, among other things: grant liens to secure indebtedness and merge with or into other companies or otherwise dispose of all or substantially all of their assets. The 4.5% Indenture also requires any non-guarantor restricted subsidiary that is a borrower under or that guarantees the Senior Secured Credit Facilities or, if the Senior Secured Credit Facilities are not outstanding, incurs certain material indebtedness, to guarantee the notes, unless such non-guarantor restricted subsidiary is a foreign
subsidiary, receivables entity or another exception applies. These covenants include significant exceptions and qualifications. The 4.5% Indenture does not directly restrict the issuer or the guarantors from incurring indebtedness, paying dividends or making other distributions, repurchasing Darling’s capital stock, or making investments. The Company capitalized approximately $10.6 million of deferred loan costs as of June 28, 2025 in connection with the 4.5% Notes.
Other than in connection with a change of control repurchase event, as described in the 4.5% Indenture, the 4.5% Issuer is not required to make mandatory redemption or sinking fund payments on the 4.5% Notes. The 4.5% Issuer may redeem some or all of the 4.5% Notes at any time prior to July 15, 2028 at a redemption price of 100% of the principal amount plus a “make-whole” premium as provided in the 4.5% Indenture. The 4.5% Notes become redeemable at any time from July 15, 2028, in whole or in part, at the fixed redemption price specified in the 4.5% Indenture.

As of June 28, 2025, the Company is in compliance with all of the financial covenants under the Amended Credit Agreement, and believes it is in compliance with all of the other covenants contained in the Amended Credit Agreement, the 6% Senior Notes due 2030, the 5.25% Senior Notes due 2027 and the 4.5% Senior Notes due 2032.

The Company has provided income taxes for the three months ended June 28, 2025 and June 29, 2024, based on its estimate of the effective tax rate for the entire 2025 and 2024 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.
 
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 28, 2025 and June 29, 2024, the Company had $10.8 million and $13.6 million, respectively, of gross unrecognized tax benefits and $2.7 million and $1.7 million, respectively, of related accrued interest and penalties. The Company’s gross unrecognized tax benefits are not expected to decrease significantly within the next twelve months.

On August 16, 2022, the U.S. government enacted the IR Act that includes tax incentives, such as the CFPC, for energy and climate initiatives. The CFPC, a new transferable income tax credit effective January 1, 2025, consolidates and replaces the refundable excise tax credits for biodiesel, renewable diesel, alternative fuel and sustainable aviation fuel mixtures (collectively the “Blenders Tax Credits”). The CFPC provides a per-gallon tax credit for producers of clean transportation fuel based on the carbon intensity of production and is calculated by multiplying the applicable amount per gallon of qualifying fuel by the emissions rates for the fuel.

On January 10, 2025, the U.S. Department of the Treasury and Internal Revenue Service released Notices 2025-10 and 2025-11, which provide clarity on issues including which entities and fuels are eligible for the credit and how taxpayers determine lifecycle emissions. In conjunction with such guidance, the Department of Energy released the 45ZCF-GREET Model allowing clean fuel producers to compute and claim the CFPC. Like the Blenders Tax Credits,
the CFPC is generated by DGD and significantly impacts our effective tax rate relative to the federal statutory rate of 21%.

On July 4, 2025, the OBBBA was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. We are currently assessing the impact of the new legislation on our financial statements.
The Company’s major taxing jurisdictions include the United States (federal and state), Canada, the Netherlands, Belgium, Brazil, Germany, France, China and Poland. 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 2013 tax year.

Fiscal 2025 Long-Term Incentive Opportunity Awards (2025 LTIP). On December 20, 2024, the Compensation Committee (the “Committee”) of the Company’s Board of Directors adopted the 2025 LTIP pursuant to which on January 3, 2025 the Company awarded certain of the Company’s key employees, 244,130 restricted stock units and 355,383 performance share units (the “PSUs”) under the Company’s 2017 Omnibus Incentive Plan. The restricted stock units 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 gross investment (“ROGI”), as calculated in accordance with the terms of the award agreement, relative to the average ROGI of the Company’s performance peer group companies, with the earned award to be determined in the first quarter of fiscal 2028, 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 (up to 225%) depending on the Company’s ROGI 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.
The Company’s Board of Directors approved a share repurchase program in August 2017, which was refreshed on June 21, 2024 up to an aggregate of $500.0 million of the Company’s Common Stock depending on market conditions, and extended to August 13, 2026. During the first six months of fiscal 2025, $34.7 million of Common Stock was repurchased under the share repurchase program. As of June 28, 2025, the Company had approximately $460.3 million remaining under the share repurchase program.

Based on annual actuarial estimates, at June 28, 2025 the Company expects to contribute approximately $4.2 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 28, 2025 and June 29, 2024 of approximately $1.3 million and $1.2 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 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 respect to the other multiemployer pension plans in which the Company participates and which are not individually significant, five plans have certified as critical or red zone as defined by the Pension Protection Act of 2006.

The Company currently has withdrawal liabilities recorded on four U.S. multiemployer plans in which it participated. As of June 28, 2025, the Company has an aggregate accrued liability of approximately $4.2 million representing the present value of scheduled withdrawal liability payments on the multiemployer plans that have given notice of withdrawal. 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, 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 interest rates, natural gas usage, diesel fuel usage, inventory, forecasted sales and foreign currency exchange rates. Interest rate swaps are
entered into with the intent of managing overall borrowing costs by reducing the potential impact of increases in interest rates on floating-rate long-term debt. 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 forwards and 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 and option 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 28, 2025, the Company had foreign exchange forward and option contracts outstanding that qualified and were designated for hedge accounting as well as corn option and forward contracts, soybean meal option contracts, other commodity forward contracts, interest rate swaps and foreign currency forward contracts that did not qualify and were not designated for hedge accounting.

In fiscal 2025 and fiscal 2024, the Company’s DGD Joint Venture entered into heating oil derivatives that were deemed to be cash flow hedges. As a result, the Company has accrued the other comprehensive income/(loss) portion belonging to Darling with an offset to the investment in DGD as required by Financial Accounting Standards Board (“FASB”) ASC Topic 323.

Cash Flow Hedges

In fiscal 2023, the Company designated interest rate swaps as cash flow hedges of the interest rate risk on a portion of its outstanding variable rate debt. Due to a change in the terms of the underlying debt instruments, the hedging relationships were dedesignated in June 2025. The cumulative gain of approximately $4.1 million, previously recognized in accumulated other comprehensive loss related to the cash flow hedges was reclassified to interest expense upon dedesignation. The interest rate swaps are still held by the Company as nondesignated hedges, carried at fair value on the balance sheet with changes in fair value recognized in interest expense. At June 28, 2025, the aggregate fair value of these interest rate swaps was approximately $5.1 million and was recorded in other current assets. At December 28, 2024, the aggregate fair value of these interest rate swaps was approximately $4.2 million and was recorded in other current assets, accrued expenses, other assets and noncurrent liabilities on the balance sheet, with an offset recorded in accumulated other comprehensive loss.

In fiscal 2023, the Company also entered into cross currency swaps that were designated as cash flow hedges to hedge the Company’s intercompany loans. During the three months ended June 28, 2025, the intercompany loans and cross currency swaps were settled. At June 28, 2025 and December 28, 2024, the aggregate fair value of these cross currency swaps was approximately zero and $22.2 million, respectively. At December 28, 2024, these amounts are included in other current assets on the balance sheet, with an offset recorded in accumulated other comprehensive loss.

In fiscal 2024 and fiscal 2025, the Company entered into foreign exchange options and forward contracts that are designated as cash flow hedges. Under the terms of the foreign exchange contracts, the Company hedged a portion of its forecasted sales in currencies other than the functional currency through the fourth quarter of fiscal 2026. At June 28, 2025 and December 28, 2024, the aggregate fair value of these foreign exchange contracts was approximately $12.3 million and $32.6 million, respectively. These amounts are included in other current assets, other long term assets, accrued expenses and other non-current liabilities on the balance sheet, with an offset recorded in accumulated other comprehensive loss.

The Company may enter into corn forward and option contracts, soybean meal forward and option contracts and heating oil swap and option contracts from time to time. There were not any open designated corn, soybean meal or heating oil contracts entered into by the Company at June 28, 2025.

As of June 28, 2025, the Company had the following designated and non-designated outstanding forward and option contract amounts that were entered into to hedge foreign currency transactions in currencies other than the functional currency and forecasted transactions in currencies other than the functional currency (in thousands):

The Company estimates the amount that will be reclassified from accumulated other comprehensive loss at June 28, 2025 into earnings over the next 12 months for all cash flow hedges will be approximately $2.2 million. As of June 28, 2025, $4.1 million has been reclassified into earnings as a result of the discontinuance of cash flow hedges.

Derivative assets and liabilities consist primarily of the Company’s corn option and future contracts, foreign currency forward and option contracts, interest rate swap contracts and cross currency swap contracts which represent the difference between observable market rates of commonly quoted intervals for similar assets and liabilities in active markets and the fixed swap rate considering the instruments term, notional amount and credit risk. See Note 15 (Derivatives) to the Company’s Consolidated Financial Statements included herein for discussion on the Company’s derivatives.

The fair value measurement of contingent consideration liability uses significant unobservable inputs (level 3). Through the quarter ended March 29, 2025, we estimated the fair value of the FASA contingent consideration using a Monte Carlo simulation methodology from a third-party that includes simulating the forecasted net income or earnings plus interest expense, taxes, depreciation and amortization (“EBITDA”) using a Geometric Brownian Motion in a risk-neutral framework. The assumptions used in the FASA contingent consideration analysis included the EBITDA forecast through the remaining term of the contingent consideration, an EBITDA discount rate, an EBITDA volatility, credit spread, risk-free rate and exchange rate. Significant increases and decreases in these inputs could result in a significantly lower or higher fair value measurement of the FASA contingent consideration. At June 28, 2025, no Monte Carlo model was used as the contingent consideration period had elapsed and actual EBITDA was known, subject to seller approval, and therefore the liability was recorded based on the actual EBITDA calculation. The changes in contingent consideration liability are due to the following:

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 various matters including labor and employment, employee benefits, occupational safety and health, wage and hour, compliance, sustainability, permitting requirements, environmental matters, including air, wastewater and storm water discharges from the Company’s processing facilities and other federal, state and local issues, 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, regulatory, governmental, environmental and litigation. At June 28, 2025 and December 28, 2024, the reserves for insurance, regulatory, governmental, environmental and litigation reflected on the balance sheet in accrued expenses and other non-current liabilities was approximately $99.3 million and $97.1 million, respectively.  The Company has insurance
recovery receivables reflected on the balance sheet in other assets of approximately $39.0 million as of June 28, 2025 and December 28, 2024, 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 pending 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 (the “Lower 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 March 2016, the Company received another letter from the EPA notifying the Company that it had issued a Record of Decision (the “ROD”) 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 made no demand on the Company and laid out a framework for remedial design/remedial action implementation under which the EPA would first seek funding from major PRPs. The letter indicated that the EPA had 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 Company 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 any of the eight contaminants of concern identified in the ROD (the “COCs”). Subsequently, the EPA conducted a settlement analysis using a third-party allocator and offered early cash out settlements to those PRPs for whom the third-party allocator determined did not discharge any of the COCs. The Company participated in this allocation process, and in November 2019, received a cash out settlement offer from the EPA in the amount of $0.6 million ($0.3 million for each of the former plant sites in question) for liabilities relating to the lower 8.3 miles of the Lower Passaic River area. The Company accepted this settlement offer, and the settlement became effective on April 16, 2021 following the completion of the EPA's administrative approval process. In September 2021, the EPA released a ROD selecting an interim remedy for the upper nine miles of the Lower Passaic River at an expected additional cost of $441 million. In October 2022, the Company, along with other settling defendants, entered into a Consent Decree with the EPA pursuant to which the Company paid $0.3 million to settle liabilities for both of the former plant sites in question related to the upper nine miles of the Lower Passaic River. The Company paid this amount into escrow, as the settlement is subject to the EPA’s administrative approval process, which includes publication, a public comment period and court approval. In December 2024, the court granted the issuance of the Consent Decree; however, this decision has been appealed. 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 Lower 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 Lower 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 Lower 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 Lower 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 Lower Passaic River. Furthermore, the Company’s settlements with the EPA described above could preclude certain of the claims alleged by OCC against the Company. 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 definitive evidence that the former Standard Tallow Corporation plant sites contributed any of the COCs 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.

Segment Reporting [Abstract]  
Business Segments Business Segments
In 2024, the Company adopted Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, on a retrospective basis.

The Company sells its products through a global network of over 260 locations across five continents within three industry segments: Feed Ingredients, Food Ingredients and Fuel Ingredients. The Company's segments are determined as those operations whose results are reviewed regularly by the chief operating decision maker (“CODM”), who is the Company's Chief Executive Officer, in deciding how to allocate resources and assess performance. Each segment is organized and managed based upon the nature of the Company's markets and customers and consists of similar products and services.

The following is a description of each segment's business operations.

Feed Ingredients
Feed Ingredients consists principally of (i) the Company’s U.S. ingredients business, including the Company’s fats and proteins, used cooking oil, trap grease, the Company's Canada ingredients business, and the ingredients and specialty products businesses conducted by Darling Ingredients International under the Sonac and FASA names (proteins, fats, and blood products) and (ii) the Company’s bakery residuals business. Feed Ingredients operations process animal by-products and used cooking oil into fats, proteins and hides.

Food Ingredients
Food Ingredients consists principally of (i) the collagen business conducted by Darling Ingredients International under the Rousselot and Gelnex names, (ii) the natural casings business conducted by Darling Ingredients International under the CTH name and (iii) certain specialty products businesses conducted by Darling Ingredients International under the Sonac name.

Fuel Ingredients
The Company’s Fuel Ingredients segment consists of (i) the Company’s investment in the DGD Joint Venture and (ii) the bioenergy business conducted by Darling Ingredients International under the Ecoson and Rendac names.

The performance of the operating segments is evaluated based on segment income (loss) which includes all revenues, operating expenses, and selling, general and administrative expenses incurred at all operating locations and excludes general corporate expenses. The CODM uses segment income (loss) as the measure to make resource (including financial or capital resources) allocation decisions for each segment, predominantly in the annual budget and forecasting process. The CODM considers budget-to-actual variances on a quarterly basis when evaluating performance for each segment and making decisions about capital allocation. Accounting policies have been applied consistently by all segments within the Company for all reporting periods. Intercompany revenue and expense amounts have been eliminated within each segment to report on the basis that management uses internally for evaluating segment performance. Our CODM is not provided with total assets by segment since we do not measure, evaluate the performance, or allocate capital resources on a segment basis. As a result, we have not disclosed any asset information by segment.

Revenue from Contract with Customer [Abstract]  
Revenue Revenue
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 an 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 Company elected to treat shipping and handling as fulfillment costs. Sales, value-add, and other taxes collected concurrently with revenue-producing activities are excluded from revenue and booked on a net basis.

The following tables present the Company revenues disaggregated by geographic area and major product types by reportable segment for the three and six months ended June 28, 2025 and June 29, 2024 (in thousands):

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, 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 28, 2025 and June 29, 2024, the Company recorded net sales to the DGD Joint Venture of approximately $291.5 million and $234.6 million, respectively. For the three months ended June 28, 2025 and June 29, 2024, our net sales to the DGD Joint Venture were approximately 20% and 16%, respectively of total net sales. For the six months
ended June 28, 2025 and June 29, 2024, the Company recorded net sales to the DGD Joint Venture of approximately $509.5 million and $481.3 million, respectively. For the six months ended June 28, 2025 and June 29, 2024, our net sales to the DGD Joint Venture were approximately 18% and 17%, respectively of total net sales. At June 28, 2025 and December 28, 2024, the Company had $18.6 million and $9.5 million in outstanding receivables due from the DGD Joint Venture, respectively. In addition, the Company has eliminated approximately $99.1 million and $55.7 million of additional sales for the six months ended June 28, 2025 and June 29, 2024, respectively, to defer the Company’s portion of profit of approximately $22.2 million and $9.5 million on those sales relating to inventory assets remaining on the DGD Joint Venture's balance sheet at June 28, 2025 and June 29, 2024, respectively.

Revolving Loan Agreement

On June 15, 2023, Darling, through its wholly owned subsidiary Darling Green Energy LLC, (“Darling Green”), and Diamond Alternative Energy, LLC, a wholly owned subsidiary of Valero (“Diamond Alternative” and together with Darling Green, the “DGD Lenders”), entered into a revolving loan agreement (the “2023 DGD Loan Agreement”) with the DGD Joint Venture, pursuant to which the DGD Lenders committed to making loans available to the DGD Joint Venture in the total amount of $200.0 million with each lender committed to $100.0 million of the total commitment. Any borrowings by the DGD Joint Venture under the 2023 DGD Loan Agreement are at the applicable annum rate equal to the sum of (a) term SOFR on such day plus (b) 2.50%. The 2023 DGD Loan Agreement expires on June 15, 2026. In January 2024, the DGD Joint Venture borrowed all $200.0 million available under the 2023 DGD Loan Agreement, including the Company’s full $100.0 million commitment, which was repaid in March 2024. The DGD Joint Venture paid interest to the Company for the three months ended June 28, 2025 and June 29, 2024 of zero, respectively and paid interest to the Company for the six months ended June 28, 2025 and June 29, 2024 of zero and $1.6 million, respectively. As of June 28, 2025 and December 28, 2024, zero was owed to Darling Green under the 2023 DGD Loan Agreement.

Guarantee Agreements

In February 2020, in connection with the DGD Joint Venture’s expansion project at its Norco, LA facility, the DGD Joint Venture entered into two agreements (the “IMTT Terminaling Agreements”) with International-Matex Tank Terminals (“IMTT”), pursuant to which the DGD Joint Venture will move raw material and finished product to and from the IMTT terminal facility by pipeline, thereby providing better logistical capabilities.  As a condition to entering into the IMTT Terminaling Agreements, IMTT required that the Company and Valero guarantee their proportionate share, up to a maximum of approximately $50 million each, of the DGD Joint Venture’s obligations under the IMTT Terminaling Agreements (the “IMTT Guarantee”), subject to the conditions provided for in the IMTT Terminaling Agreements. The Company has not recorded any liability as a result of the IMTT Guarantee, as the Company believes the likelihood of having to make any payments under the IMTT Guarantee is remote.

In April 2021, in connection with the DGD Joint Venture’s expansion project at its Port Arthur, TX facility, the DGD Joint Venture entered into two agreements (the “GTL Terminaling Agreements”) with GT Logistics, LLC (“GTL”), pursuant to which the DGD Joint Venture will move raw material and finished product to and from the GTL terminal facility by pipeline, thereby providing better logistical capabilities. As a condition to entering into the GTL Terminaling Agreements, GTL required that the Company and Valero guarantee their proportionate share, up to a maximum of approximately $160 million each, of the DGD Joint Venture’s obligations under the GTL Terminaling Agreements (the “GTL Guarantee”), subject to the conditions provided for in the GTL Terminaling Agreements. The maximum amount of the GTL Guarantee is reduced over the 20-year initial term of the GTL Terminaling Agreements as the termination fee under such agreements declines. The Company has not recorded any liability as a result of the GTL Guarantee, as the Company believes the likelihood of having to make any payments under the GTL Guarantee is remote.

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’s consolidated subsidiaries' net assets held by parties other than the Company. These ownership interests are presented separately as “Noncontrolling interests” within “Stockholders' Equity.” All 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 28, 2025, and include the 13 and 26 weeks ended June 28, 2025, and the 13 and 26 weeks ended June 29, 2024.
Cash and Cash Equivalents Cash and Cash Equivalents
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. Restricted cash shown on the Consolidated Balance Sheet as of June 28, 2025 and December 28, 2024, primarily represents the current portion of acquisition consideration hold-back amounts that are part of the purchase price set aside in escrow in the Company’s name for possible indemnification claims by the Company, which amounts will be paid to the sellers in the future if no claims arise. Restricted cash included in other long term assets on the Consolidated Balance Sheet as of June 28, 2025 and December 28, 2024, primarily represents the long term acquisition consideration hold-back amounts that are part of the purchase price set aside in escrow in the Company’s name for possible indemnification claims by the Company, which amounts will be paid to the sellers in the future if no claims arise. A reconciliation of cash, cash equivalents, and restricted cash reported
within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statement of Cash flows is as follows (in thousands):

Total cash, cash equivalents and restricted cash shown in the statement of cash flows$218,709 $217,307 
Revenue Recognition Revenue RecognitionThe 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 in accrued expenses and recognized when control of the promised finished product is transferred to the Company’s customer.
Use of Estimates Use of Estimates
The preparation of the consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

If it is at least reasonably possible that the estimate of the effect on the financial statements of a condition, situation, or set of circumstances that exist at the date of the financial statements will change in the near term due to one or more future confirming events, and the effect of the change would be material to the financial statements, the Company will disclose the nature of the uncertainty and include an indication that it is at least reasonably possible that a change in the estimate will occur in the near term.  If the estimate involves certain loss contingencies, the disclosure will also include an estimate of the probable loss or range of loss or state that an estimate cannot be made.

As a result of the Russia-Ukraine war and the ongoing or emerging conflicts in the Middle East and the current inflationary environment that might be further impacted by tariffs, we have evaluated the potential impact to the Company’s operations and for any indicators of triggering events that could indicate certain of the Company’s assets may be impaired. Through the six months ended June 28, 2025, the Company has not observed any impairments of the Company’s assets or a significant change in their fair value due to the Russia-Ukraine war and the ongoing or emerging conflicts in the Middle East or inflation or the impacts of tariffs.
Earnings Per Share Earnings Per ShareBasic income 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.
Income Taxes The Company has provided income taxes for the three months ended June 28, 2025 and June 29, 2024, based on its estimate of the effective tax rate for the entire 2025 and 2024 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.
