Organization, Consolidation and Presentation of Financial Statements [Abstract]
Condensed Consolidated Financial Statements	Condensed Consolidated Financial Statements The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal and recurring adjustments unless otherwise disclosed) considered necessary for a fair presentation have been included. Operating results for the three months ended March 26, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. For further information, refer to the consolidated financial statements and notes thereto included in the Company’s annual report on Form 10-K for the year ended December 25, 2022. The Company operates on the basis of a 52/53 week fiscal year ending on the Sunday falling on or before December 31. Any reference we make to a particular year (for example, 2023) in the notes to these Condensed Consolidated Financial Statements applies to our fiscal year and not the calendar year. The three months ended March 26, 2023 represents the period from December 26, 2022 through March 26, 2023. The three months ended March 27, 2022 represents the period from December 27, 2021 through March 27, 2022. The Condensed Consolidated Financial Statements include the accounts of the Company and its majority-owned subsidiaries. We eliminate all significant affiliate accounts and transactions upon consolidation. The Condensed Consolidated Financial Statements have been prepared in conformity with U.S. GAAP using management’s best estimates and judgments. These estimates and judgments affect the reported amounts of assets and liabilities and disclosure of the contingent assets and liabilities at the date of the financial statements. The estimates and judgments will also affect the reported amounts for certain revenues and expenses during the reporting period. Actual results could differ materially from these estimates and judgments. Significant estimates made by the Company include the allowance for credit losses, reserves related to inventory obsolescence or valuation, useful lives of long-lived assets, goodwill, valuation of deferred tax assets, insurance accruals, valuation of pension and other postretirement benefits obligations, income tax accruals, certain derivative positions, certain litigation reserves and valuations of acquired businesses.
Foreign Currency Transactions and Translations	The functional currency of the Company’s U.S. and Mexico operations and certain holding-company subsidiaries in Luxembourg, the U.K., Malta and the Republic of Ireland is the U.S. dollar. The functional currency of its U.K. operations is the British pound. The functional currency of the Company’s operations in France, the Netherlands and the Republic of Ireland is the euro. For foreign currency-denominated entities other than the Company’s Mexico operations, translation from local currencies into U.S. dollars is performed for most assets and liabilities using the exchange rates in effect as of the balance sheet date. Income and expense accounts are remeasured using average exchange rates for the period. Adjustments resulting from translation of these financial records are reflected as a separate component of Accumulated other comprehensive loss in the Condensed Consolidated Balance Sheets. For the Company’s Mexico operations, remeasurement from the Mexican peso to U.S. dollars is performed for monetary assets and liabilities using the exchange rate in effect as of the balance sheet date. Remeasurement is performed for non-monetary assets using the historical exchange rate in effect on the date of each asset’s acquisition. Income and expense accounts are remeasured using average exchange rates for the period. Net adjustments resulting from remeasurement of these financial records, as well as foreign currency transaction gains and losses, are reflected in Foreign currency transaction losses in the Condensed Consolidated Statements of Income.
Restricted Cash	Restricted Cash and Restricted Cash Equivalents The Company is required to maintain cash balances with a broker as collateral for exchange-traded futures contracts. These balances are classified as restricted cash as they are not available for use by the Company to fund daily operations. The balance of restricted cash and restricted cash equivalents may also include investments in U.S. Treasury Bills that qualify as restricted cash equivalents, as required by the broker, to offset the obligation to return cash collateral.
Recent Accounting Pronouncements	Accounting Pronouncements Adopted in 2023 In September 2022, the FASB issued ASU 2022-04, Liabilities - Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations, which requires disclosure of the existence of supplier financing programs. The guidance requires disclosure about the nature of the supplier financing agreements, including key terms and payment timing and determination of amounts, the accounting treatment for the transactions and the effect of the transactions on the financial statements, as well as any assets pledged or guarantees provided to the providers of the financing programs. The provisions of the new guidance were effective for years beginning after December 15, 2022 with the requirement to add rollforward disclosures for years beginning after December 15, 2023. The Company adopted this guidance effective December 26, 2022. The adoption of this guidance did not have a material impact on our Condensed Consolidated Financial Statements. Additional information regarding supplier finance programs is included in “Note 10. Supplier Finance Programs.” In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions to the application of current GAAP to existing contracts, hedging relationships and other transactions affected by reference rate reform. The new guidance will ease the transition to new reference rates by allowing entities to update contracts and hedging relationships without applying many of the contract modification requirements specific to those contracts. The provisions of the new guidance are effective beginning March 12, 2020, extending through December 31, 2022 with the option to apply the guidance at any point during that time period. In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848), which provides further clarification on the scope of Topic 848 so that derivatives affected by the discounting transition are explicitly eligible for certain optional expedients and exceptions in Topic 848. Once an entity elects an expedient or exception it must be applied to all eligible contracts or transactions. We currently have hedging transactions and debt agreements that reference LIBOR and will apply the new guidance as these contracts are modified to reference other rates. The Company adopted this guidance effective December 26, 2022. The adoption did not have a material impact on our Condensed Consolidated Financial Statements.
Revenue	The vast majority of the Company’s revenue is derived from contracts which are based upon a customer ordering our products. While there may be master agreements, the contract is only established when the customer’s order is accepted by the Company. The Company accounts for a contract, which may be verbal or written, when it is approved and committed by both parties, the rights of the parties are identified along with payment terms, the contract has commercial substance and collectability is probable. The Company evaluates the transaction for distinct performance obligations, which are the sale of its products to customers. Since its products are commodity market-priced, the sales price is representative of the observable, standalone selling price. Each performance obligation is recognized based upon a pattern of recognition that reflects the transfer of control to the customer at a point in time, which is upon destination (customer location or port of destination), which faithfully depicts the transfer of control and recognition of revenue. There are instances of customer pick-up at the Company’s facility, in which case control transfers to the customer at that point and the Company recognizes revenue. The Company’s performance obligations are typically fulfilled within days to weeks of the acceptance of the order. The Company makes judgments regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from revenue and cash flows with customers. Determination of a contract requires evaluation and judgment along with the estimation of the total contract value and if any of the contract value is constrained. Due to the nature of our business, there is minimal variable consideration, as the contract is established at the acceptance of the order from the customer. When applicable, variable consideration is estimated at contract inception and updated on a regular basis until the contract is completed. Allocating the transaction price to a specific performance obligation based upon the relative standalone selling prices includes estimating the standalone selling prices including discounts and variable consideration. Contract Costs The Company can incur incremental costs to obtain or fulfill a contract such as broker expenses that are not expected to be recovered. The amortization period for such expenses is less than one year; therefore, the costs are expensed as incurred. Taxes The Company excludes all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity from a customer (for example, sales, use, value added and some excise taxes) from the transaction price. Contract Balances The Company receives payment from customers based on terms established with the customer. Payments are typically due within 14 to 30 days of delivery. Revenue contract liabilities relate to payments received in advance of satisfying the performance under the customer contract. The revenue contract liabilities relate to customer prepayments and the advanced consideration, such as cash, received from governmental agency contracts for which performance obligations to the end customer have not been satisfied.
Accounts Receivable	Accounts Receivable The Company records accounts receivable when revenue is recognized. We record an allowance for credit losses, reducing our receivables balance to an amount we estimate is collectible from our customers. Estimates used in determining the allowance for credit losses are based on historical collection experience, current trends, aging of accounts receivable and periodic credit evaluations of our customers’ financial condition. We write off accounts receivable when it becomes apparent, based upon age or customer circumstances, that such amounts will not be collected. Generally, the Company does not require collateral for its accounts receivable.
