Restructuring and Related Activities [Abstract]
Growth, Reinvestment, and Restructuring Programs	3. GROWTH, REINVESTMENT, AND RESTRUCTURING PROGRAMS The Company’s growth, reinvestment, and restructuring activities are part of an enterprise-wide transformation to build long-term sustainable growth and improve profitability for the Company. These activities are aggregated into the following categories: (1) Strategic Growth Initiatives (expected completion in 2023) – a growth and reinvestment strategy, (2) Structure to Win (completed in 2020) – an operating expense improvement program, (3) TreeHouse 2020 (completed in 2020) – a long-term growth and margin improvement strategy, and (4) other (collectively the "Growth, Reinvestment, and Restructuring Programs"). Below is a description of each of the Growth, Reinvestment, and Restructuring Programs: (1) Strategic Growth Initiatives In the first quarter of 2021, the Company began executing on its growth and reinvestment initiatives designed to invest in our commercial organization, adapt the supply chain to better support long-term growth opportunities, and further enable the Company to build greater depth in growth categories. These initiatives are intended to better position the Company to accelerate future revenue and earnings growth, and improve the execution of our strategy to be our customer's preferred manufacturing and distribution partner. This reinvestment will occur through 2023, and the Company currently expects the total costs will be up to $130.0 million, comprised of consulting and professional fees, employee-related costs, and investment in information technology. Consulting and professional fees are expected to include building marketing competencies, furthering our e-commerce strategy and digital capabilities, and advancing automation and value engineering in our supply chain network. Employee-related costs primarily consist of dedicated employee costs. (2) Structure to Win In the first quarter of 2018, the Company announced an operating expenses improvement restructuring program ("Structure to Win") designed to align our organizational structure with strategic priorities. The program was intended to drive operational effectiveness, cost reduction, and position the Company for growth with a focus on a lean customer-centric go-to-market team, centralized supply chain, and streamlined administrative functions. This program was completed in 2020. Total costs within this program were $92.7 million, comprised primarily of consulting and professional fees, severance, dedicated employee costs, and Corporate office closing costs. (3) TreeHouse 2020 In the third quarter of 2017, the Company announced TreeHouse 2020, a program intended to accelerate long-term growth through optimization of our manufacturing network, transformation of our mixing centers and warehouse footprint, and leveraging of systems and processes to drive performance. The Company's workstreams related to these activities and selling, general, and administrative cost reductions were intended to increase our capacity utilization, expand operating margins, and streamline our plant structure to optimize our supply chain. This program was completed in 2020. Total costs within this program were $299.8 million, comprised primarily of consulting and professional fees, severance, dedicated employee costs, and accelerated depreciation for plant and other office closures. (4) Other Other costs include restructuring costs incurred for costs to exit facilities, information technology system implementation, severance, and other administrative costs. The costs by activity for the Growth, Reinvestment, and Restructuring Programs are outlined below: Three Months Ended Six Months Ended 2021 2020 2021 2020 (In millions) Strategic growth initiatives $ 14.5 $ — $ 30.6 $ — Structure to Win — 3.0 — 10.8 TreeHouse 2020 — 8.8 — 20.9 Other 7.7 — 11.2 — Total $ 22.2 $ 11.8 $ 41.8 $ 31.7 As part of our growth, reinvestment, and restructuring programs, we generally incur expenses that qualify as exit and disposal costs under U.S. GAAP. These include severance and employee separation costs and other exit costs. Severance and employee separation costs primarily relate to cash severance, non-cash severance, including accelerated equity award compensation expense, pension, and other termination benefits. Other exit costs typically relate to lease and contract terminations. We also incur expenses that are an integral component of, and directly attributable to, our growth, reinvestment, and restructuring activities, which do not qualify as exit and disposal costs under U.S. GAAP. These include asset-related costs and other costs. Asset-related costs primarily relate to accelerated depreciation and certain long-lived asset impairments. Other costs primarily relate to start-up costs of new facilities, consulting and professional fees, information technology implementation, asset relocation costs, and costs to exit facilities. Expenses associated with these programs are recorded in Cost of sales, General and administrative, and Other operating expense, net in the Condensed Consolidated Statements of Operations. The Company does not allocate costs associated with Growth, Reinvestment, and Restructuring Programs to reportable segments when evaluating the performance of its segments. As a result, costs associated with Growth, Reinvestment, and Restructuring Programs are not presented by reportable segment. Refer to Note 17 for additional information. Below is a summary of costs by line item for the Growth, Reinvestment, and Restructuring Programs: Three Months Ended Six Months Ended 2021 2020 2021 2020 (In millions) Cost of sales $ — $ — $ — $ 0.7 General and administrative — 0.3 — 1.0 Other operating expense, net 22.2 11.5 41.8 30.0 Total $ 22.2 $ 11.8 $ 41.8 $ 31.7 Below is a summary of costs by type associated with the Growth, Reinvestment, and Restructuring Programs: Three Months Ended Six Months Ended 2021 2020 2021 2020 (In millions) Employee-related $ 7.1 $ 1.9 $ 12.0 $ 6.7 Other costs 15.1 9.9 29.8 25.0 Total $ 22.2 $ 11.8 $ 41.8 $ 31.7 For the three and six months ended June 30, 2021 and 2020, employee-related costs primarily consisted of dedicated project employee cost, severance, and retention; and other costs primarily consisted of consulting services.

Receivables Sales Program

Receivables Sales Program	6 Months Ended

Receivables [Abstract]
Receivables Sales Program	4. RECEIVABLES SALES PROGRAM In December 2017 and June 2019, the Company entered into agreements to sell certain trade accounts receivable to two unrelated, third-party financial institutions (collectively, "the Receivables Sales Program"). The agreements can be terminated by either party with 60 days' notice. The Receivables Sales Program is used by the Company to manage liquidity in a cost-effective manner. The Company has no retained interest in the receivables sold under the Receivables Sales Program; however, under the agreements the Company does have collection and administrative responsibilities for the sold receivables. Under the Receivables Sales Program, the maximum amount of receivables that may be sold at any time is $300.0 million.

Business Combination and Asset Acquisition [Abstract]
Acquisitions and Divestitures	6. ACQUISITIONS AND DIVESTITURES Acquisitions Pasta Acquisition On December 11, 2020, the Company completed the acquisition of the majority of the U.S. branded pasta portfolio as well as a manufacturing facility in St. Louis, Missouri of Riviana Foods, Inc. ("Riviana Foods"), a subsidiary of Ebro Foods, S.A. ("Ebro Foods") for a total purchase price of approximately $244.3 million in cash. Ebro Foods is a Spanish-based multinational food group operating primarily in the pasta and rice sectors. The acquisition includes the following brands: Skinner, No Yolks, American Beauty, Creamette, San Giorgio, Prince, Light 'n Fluffy, Mrs. Weiss', Wacky Mac, P&R Procino-Rossi, and New Mill. During the second quarter of 2021, the Company exercised its call option to acquire machinery and equipment utilized in the Riviana Foods Fresno, California facility, which increased the purchase consideration by $5.1 million, and was allocated to goodwill at $1.3 million and property, plant, and equipment, net at $3.8 million. The acquisition is expected to strengthen the Company's portfolio and expand its scale to better serve its national and regional customers. The acquisition was funded from the Company's existing cash resources. The pasta acquisition was accounted for under the acquisition method of accounting and the results of operations were included in our Consolidated Financial Statements from the date of acquisition in the Meal Preparation segment. The following table summarizes the preliminary purchase price allocation of the fair value of net tangible and intangible assets acquired and liabilities assumed: (In millions) Original consideration $ 239.2 Call option exercised 5.1 Total consideration transferred $ 244.3 Allocation of consideration to assets acquired and liabilities assumed: Inventories $ 20.0 Property, plant, and equipment, net 50.9 Customer relationships 68.0 Trade names 43.0 Formulas/recipes 2.3 Goodwill 60.2 Operating lease right-of-use assets 0.1 Assets acquired 244.5 Assumed liabilities (0.2) Total purchase price $ 244.3 The Company allocated the intangible assets acquired to the Meal Preparation segment which included $68.0 million of customer relationships with an estimated life of 20 years, $43.0 million of trade names with an estimated life of 20 years, and $2.3 million of formulas/recipes with estimated life of 5 years. The aforementioned intangible assets will be amortized over their estimated useful lives. The Company increased the cost of acquired inventories by approximately $3.1 million as of December 31, 2020. No expense was incurred during the three months ended June 30, 2021, and $1.0 million was expensed as a component of Cost of sales during the six months ended June 30, 2021 for the amortization of the inventory step up adjustment. The Company has allocated $60.2 million of goodwill to the Meal Preparation segment. Goodwill arises principally as a result of expansion opportunities of its scale to better serve its regional and national customers and plant operation synergies across its legacy Pasta category. The goodwill resulting from this acquisition is tax deductible. The purchase price allocation in the table above is preliminary and subject to the finalization of the Company's valuation analysis. During the second quarter of 2021, the Company recorded a purchase price adjustment which increased goodwill and decreased property, plant, and equipment, net by $1.1 million. The fair values for customer relationships at the acquisition date were determined using the excess earnings method under the income approach. Trade name fair values were determined using the relief from royalty method, while the fair value of formulas/recipes was determined using the cost approach. Real property and personal property fair values were determined using the cost approach. The fair value measurements of intangible assets are based on significant unobservable inputs, and thus represent Level 3 inputs. Significant assumptions used in assessing the fair values of intangible assets include discounted future cash flows, customer attrition rates, and royalty rates. The following unaudited pro forma information shows the results of operations for the Company as if its pasta acquisition had been completed as of January 1, 2019. Adjustments have been made for the pro forma effects of depreciation and amortization of tangible and intangible assets recognized as part of the business combination and related income taxes. The pro forma results may not necessarily reflect actual results of operations that would have been achieved, nor are they necessarily indicative of future results of operations.

("Post") for a base purchase price of $85.0 million. The Company classified the proceeds within Net cash provided by (used in) investing activities - discontinued operations, and a pre-tax gain was recognized on the transaction upon closing of $18.4 million as a component of Net income from discontinued operations in the Condensed Consolidated Statements of Operations. The pre-tax gain recognized was a result of the sale proceeds received being at the high end of the range of management's previous estimate of the disposal group's fair value. The sale of this business is part of the Company's portfolio optimization strategy. RTE Cereal operated as two manufacturing plants located in Lancaster, Ohio and Sparks, Nevada. The Company entered into a Transition Services Agreement ("TSA") with Post, which is designed to ensure and facilitate an orderly transfer of business operations. The services provided under the TSA terminate at various times up to twelve months from the date of sale and can be renewed with a maximum of an additional six-month period for certain services. The income received under the TSA was not material for the three and six months ended June 30, 2021 and is primarily classified within General and administrative expenses or Cost of sales in the Company's Condensed Consolidated Statements of Operations depending on the functions being supported by the Company. The Company has reflected the RTE Cereal business as a discontinued operation for all periods presented through the date of sale. Unless otherwise noted, amounts and disclosures throughout these Notes to Condensed Consolidated Financial Statements relate to the Company's continuing operations. Prior to the sale, there were expected disposal loss adjustments of $0.3 million recognized as an impairment charge during both the six months ended June 30, 2021 and 2020, and no impairment adjustments were recognized during both the three months ended June 30, 2021 and 2020 within Net income from discontinued operations.

These two facilities were included within the Snacking & Beverages reporting segment. On April 17, 2020, the sale of these facilities was completed for $26.9 million. The Company recognized a loss upon divestiture of $0.3 million within Other operating expense, net in the Condensed Consolidated Statements of Operations during the three and six months ended June 30, 2020.

The change in the Company's effective tax rate for the three and six months ended June 30, 2021 compared to 2020 is primarily the result of a benefit recognized in 2020 due to the enactment of the "Coronavirus Aid, Relief, and Economic Security Act" (the "CARES Act"), a tax benefit recognized in 2020 due to our cross-border intercompany financing structure, and a change in the amount of non-deductible executive compensation. Our effective tax rate may change from period to period based on recurring and non-recurring factors, including the jurisdictional mix of earnings, enacted tax legislation, state income taxes, settlement of tax audits, and the expiration of the statute of limitations in relation to unrecognized tax benefits.

Under the Plan, the Compensation Committee may grant awards of various types of compensation, including stock options, restricted stock, restricted stock units, performance shares, performance units, other types of stock-based awards, and other cash-based compensation. The maximum number of shares available to be awarded under the Plan is approximately 17.5 million, of which approximately 3.6 million remained available at June 30, 2021. Total compensation expense related to stock-based payments and the related income tax benefit recognized in Net loss from continuing operations are as follows: Three Months Ended Six Months Ended 2021 2020 2021 2020 (In millions) (In millions) Compensation expense related to stock-based payments $ 4.5 $ 7.0 $ 9.4 $ 14.9 Related income tax benefit 1.1 1.8 2.5 3.9 All amounts below include continuing and discontinued operations. Restricted Stock Units — Employee restricted stock unit awards generally vest based on the passage of time in approximately three equal installments on each of the first three anniversaries of the grant date. Director restricted stock units generally vest on the first anniversary of the grant date. Certain directors have elected to defer receipt of their awards until either their departure from the Board of Directors or a specified date beyond the first anniversary of the grant date. The following table summarizes the restricted stock unit activity during the six months ended June 30, 2021: Employee Weighted Director Weighted (In thousands) (In thousands) Outstanding, at December 31, 2020 707 $ 47.92 125 $ 54.67 Granted 346 52.04 37 48.03 Vested (313) 46.77 (69) 57.03 Forfeited (92) 51.22 (1) 52.46 Outstanding, at June 30, 2021 648 50.24 92 50.20 Vested and deferred, at June 30, 2021 50 52.32 Three Months Ended Six Months Ended 2021 2020 2021 2020 (In millions) (In millions) Fair value of vested restricted stock units $ 3.6 $ 1.8 $ 20.0 $ 10.2 Tax benefit recognized from vested restricted stock units 0.9 0.5 3.2 1.9 Future compensation costs related to restricted stock units are approximately $29.7 million as of June 30, 2021 and will be recognized on a weighted average basis over the next 2.1 years. The grant date fair value of the awards is equal to the Company's closing stock price on the grant date. Performance Units — Performance unit awards are granted to certain members of management. These awards contain both service and performance conditions. For awards granted in years prior to 2020, for each year of the three-year performance period, one-third of the units will accrue, multiplied by a predefined percentage generally between 0% and 200%, depending on the achievement of certain operating performance measures. Accrued shares are not earned until the end of the full three-year performance period. For performance unit awards granted in 2020 and 2021, performance goals are set and measured annually with one-quarter of the units eligible to accrue for each year in the three-year performance period. Accrued shares are earned at the end of the three-year performance period. Additionally, for the cumulative three-year performance period, one-quarter of the units will accrue. In 2021, certain executive members of management received awards that had a market condition as described below. For both the annual and cumulative shares, the earned shares are equal to the number of units granted multiplied by a predefined percentage generally between 0% and 200%, depending on the achievement of certain operating performance measures. Accrued units will be converted to stock or cash, at the discretion of the Compensation Committee, generally, on the third anniversary of the grant date. The Company intends to settle these awards in stock and has the shares available to do so. In 2021, the Compensation Committee of the Board approved performance unit awards granted to certain executive members of management that include a relative total shareholder return market condition that is measured over a three-year performance period in addition to the existing operating performance measures. The units will accrue, multiplied by a predefined percentage generally between 0% and 200% for the operating performance measures and 0% and 150% for the relative total shareholder return measure, depending on the achievement attained for each performance measure. The fair value of the portion of the award earned based on relative total shareholder return was valued using a Monte Carlo simulation model with a grant-date fair value of $59.16 on approximately 23,200 units granted. These awards will be converted to stock or cash, at the discretion of the Compensation Committee, generally, on the third anniversary of the grant date. The Company intends to settle these awards in stock and has the shares available to do so.

Reed, et al. , Case No. 17-cv-01014, in the Northern District of Illinois, against TreeHouse and certain of its officers. This complaint is also purportedly brought derivatively on behalf of TreeHouse, and it asserts state law claims against certain officers for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and corporate waste. On February 8, 2019, another purported TreeHouse shareholder filed an action captioned Bartelt v. Reed, et al. , Case No. 1:19-cv-00835, in the United States District Court for the Northern District of Illinois. This complaint is purportedly brought derivatively on behalf of TreeHouse and asserts state law claims against certain officers for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and corporate waste, in addition to asserting violations of Section 14 of the Securities Exchange Act of 1934. Finally, on June 3, 2019, another purported TreeHouse shareholder filed an action captioned City of Ann Arbor Employees' Retirement System v. Reed, et al. , Case No. 2019-CH-06753, in the Circuit Court of Cook County, Illinois, against TreeHouse and certain of its officers. Like Wells , Lavin , and Bartelt , this complaint is purportedly brought derivatively on behalf of TreeHouse and asserts claims for contribution and indemnification, breach of fiduciary duty, and aiding and abetting breaches of fiduciary duty. All five complaints make substantially similar allegations (though the amended complaint in Tarara now contains additional detail). Essentially, the complaints allege that TreeHouse, under the authority and control of the individual defendants: (i) made certain false and misleading statements regarding the Company's business, operations, and future prospects; and (ii) failed to disclose that (a) the Company's private label business was underperforming; (b) the Company's Flagstone business was underperforming; (c) the Company's acquisition strategy was underperforming; (d) the Company had overstated its full-year 2016 guidance; and (e) TreeHouse's statements lacked reasonable basis. The complaints allege that these actions artificially inflated the market price of TreeHouse common stock during the class period, thus purportedly harming investors. The Bartelt action also includes substantially similar allegations concerning events in 2017, and the Ann Arbor complaint also seeks contribution from the individual defendants for losses incurred by the company in these litigations. We believe that these claims are without merit and intend to defend against them vigorously, but note that, as described below, an agreement in principle has been reached to resolve the federal securities class action. Due to the similarity of the complaints, the parties in Wells and Lavin entered stipulations deferring the litigation until the earlier of (i) the court in Public Employees' entering an order resolving defendants' anticipated motion to dismiss therein or (ii) plaintiffs' counsel receiving notification of a settlement of Public Employees' or until otherwise agreed to by the parties. On September 27, 2018, the parties in Wells and Lavin filed joint motions for entry of agreed orders further deferring the matters in light of the Public Employees' Court's denial of the motion to dismiss in February 2018. The Wells and Lavin Courts entered the agreed orders further deferring the matters on September 27, 2018 and October 10, 2018, respectively. On June 25, 2019, the parties jointly moved to consolidate the Bartelt matter with Lavin , so that it would be subject to the Lavin deferral order. This motion was granted on June 27, 2019, and Bartelt is now consolidated with Lavin and deferred. The parties filed a status report on April 13, 2021. Similarly, Ann Arbor was consolidated with Wells on August 13, 2019, and is now deferred. On February 8, 2021, the plaintiffs in Wells moved to modify the deferral order to lift the stay, and defendants thereafter opposed the motion. On April 15, 2021, the court denied the motion and set a status hearing for July 15, 2021. On July 12, 2021, the parties entered a joint status report, informing the court that the securities class action settlement was not yet approved. The July 15 status hearing was stricken, and another status hearing is set for October 18, 2021. Since its initial docketing, the Tarara matter has been re-captioned as Public Employees' Retirement Systems of Mississippi v. TreeHouse Foods, Inc., et al. , in accordance with the Court's order appointing Public Employees' Retirement Systems of Mississippi as the lead plaintiff. On May 26, 2017, the Public Employees' defendants filed a motion to dismiss, which the court denied on February 12, 2018. On April 12, 2018, the Public Employees' defendants filed their answer to the amended complaint. On April 23, 2018, the parties filed a joint status report with the Court, which set forth a proposed discovery and briefing schedule for the Court's consideration. On July 13, 2018, lead plaintiff filed a motion to certify the class, and defendants filed their response in opposition to the motion to certify the class on October 8, 2018. On November 12, 2018, the parties filed an agreed motion to stay proceedings to allow them to explore mediation. The motion was granted on November 19. The parties thereafter engaged in mediation but failed to resolve the dispute. On March 29, 2019, the parties resumed litigation by filing an agreed motion for extension of time, which was granted on April 9. Under that schedule, lead plaintiff filed its reply class certification brief on May 17, 2019. On February 26, 2020, the court granted lead plaintiff's motion for class certification. Defendants then filed a petition for permissive appeal of the class certification order in the United States Court of Appeals for the Seventh Circuit on March 11, 2020. After ordering lead plaintiff to file a response, the court denied the petition on May 4, 2020. On December 16, 2019, the parties agreed to extend the case schedule 90 days. This agreed motion was granted on December 25, 2019. At a status conference on March 10, 2020, the parties informed the court that they intended to engage in a second mediation and the court extended then-upcoming deadlines under the case schedule, pending a further status report from the parties regarding the extent of the stay needed to facilitate mediation. The court subsequently issued multiple general orders as a result of the COVID-19 outbreak, which together postponed all case deadlines for a total of 77 days. On June 9, 2020, the parties filed a joint status report informing the court that mediation had been scheduled for July 9, 2020. The next day, the court stayed the case pending the outcome of mediation. Any in-person mediation was thereafter postponed due to ongoing COVID-19 concerns, and the parties proceeded to mediate remotely. On April 19, 2021, the parties advised the Court that they have reached an agreement in principle to resolve the matter, subject to various conditions, definitive documentation, and Court approval. On July 14, 2021, the parties filed a stipulation of settlement and moved for preliminary approval of the settlement. The agreement includes a cash payment of $27.0 million (funded by D&O insurance) in exchange for dismissal with prejudice of the class claims and full releases. As a result of these developments, the Company has an accrual for a $27.0 million liability and a corresponding insurance receivable within Accrued expenses and Prepaid expenses and other current assets, respectively, in the Condensed Consolidated Balance Sheets as of June 30, 2021. On July 27, 2021, the court granted the motion for preliminary approval of the settlement and scheduled a final approval hearing for November 16, 2021. The Company is party to matters challenging its wage and hour practices. These matters include a number of class actions consolidated under the caption Negrete v. Ralcorp Holdings, Inc ., et al, pending in the U.S. District Court for the Central District of California, in which plaintiffs allege a pattern of violations of California and/or federal law at three former Company manufacturing facilities in California. The Company has notified the Court that it has reached a preliminary settlement understanding with the Negrete plaintiffs that would resolve all associated matters for a payment by the Company of $9.0 million. The preliminary understanding reached with the Negrete plaintiffs involves procedural requirements and Court approval which may continue through 2021. As a result of these developments, the Company has an accrual for a $9.0 million liability within Accrued expenses in the Condensed Consolidated Balance Sheets as of June 30, 2021. In addition, the Company is party in the ordinary course of business to certain claims, litigation, audits, and investigations. The Company will record an accrual for a loss contingency when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The Company believes it has established adequate accruals for liabilities that are probable and reasonably estimable that may be incurred in connection with any such currently pending or threatened matter, none of which are significant. In the Company's opinion, the settlement of any such currently pending or threatened matter is not expected to have a material impact on the Company's financial position, results of operations, or cash flows. In February 2014, TreeHouse, along with its 100% owned subsidiaries, Bay Valley Foods, LLC and Sturm Foods, Inc., filed suit against Keurig Dr. Pepper Inc.'s wholly-owned subsidiary, Keurig Green Mountain ("KGM"), in the U.S. District Court for the Southern District of New York ("SDNY") captioned TreeHouse Foods, Inc. et al. v. Green Mountain Coffee Roasters, Inc. et al . TreeHouse asserted claims under the federal antitrust laws and various state antitrust laws and unfair competition statutes, contending that KGM had monopolized alleged markets for single serve coffee brewers and single serve coffee pods. TreeHouse is seeking monetary damages, declaratory relief, injunctive relief, and attorneys' fees. KGM is denying the allegations made by TreeHouse in the litigation. As such, TreeHouse has not recorded any amount in its Condensed Consolidated Financial Statements as of June 30, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	16. DERIVATIVE INSTRUMENTS The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by derivative instruments include interest rate risk, foreign currency risk, commodity price risk, and market risk associated with the unfunded portion of the Company's deferred compensation liability. Derivative contracts are entered into for periods consistent with the related underlying exposure and do not constitute positions independent of those exposures. The Company does not enter into derivative instruments for trading or speculative purposes. Interest Rate Swap Agreements - The Company manages its exposure to changes in interest rates by optimizing the use of variable-rate and fixed-rate debt and by utilizing interest rate swaps to hedge our exposure to changes in interest rates, to reduce the volatility of our financing costs, and to achieve a desired proportion of fixed versus floating-rate debt, based on current and projected market conditions. As of June 30, 2021, the Company had entered into $875.0 million of long-term interest rate swap agreements to lock into a fixed LIBOR interest rate base. Under the terms of the agreements, $875.0 million in variable-rate debt was swapped for a weighted average fixed interest rate base of approximately 2.68% in 2020 and 2.91% from 2021 through 2025. These instruments are not accounted for under hedge accounting and the changes in their fair value are recognized in the Condensed Consolidated Statements of Operations. Foreign Currency Contracts - Due to the Company's foreign operations, it is exposed to foreign currency risk. The Company enters into foreign currency contracts to manage the risk associated with foreign currency cash flows. This includes, but is not limited to, using foreign currency contracts to establish a fixed foreign currency exchange rate for the net cash flow requirements for purchases of inventory, sales of finished goods, and future settlement of foreign-denominated assets and liabilities. These contracts do not qualify for hedge accounting and changes in their fair value are recognized in the Condensed Consolidated Statements of Operations. As of June 30, 2021, the Company had $6.1 million of foreign currency contracts outstanding, expiring throughout 2021 and 2022. Commodity Contracts - Certain commodities the Company uses in the production and distribution of its products are exposed to market price risk. The Company utilizes derivative contracts to manage this risk. The majority of commodity forward contracts are not derivatives, and those that are generally qualify for the normal purchases and normal sales scope exception under the guidance for derivative instruments and hedging activities and, therefore, are not subject to its provisions. For derivative commodity contracts that do not qualify for the normal purchases and normal sales scope exception, the Company records their fair value on the Condensed Consolidated Balance Sheets, with changes in value being recognized in the Condensed Consolidated Statements of Operations. The Company's derivative commodity contracts may include contracts for diesel, oil, plastics, natural gas, electricity, resin, corn, coffee, flour, and other commodity contracts that do not meet the requirements for the normal purchases and normal sales scope exception. Diesel contracts are used to manage the Company's risk associated with the underlying cost of diesel fuel used to deliver products. Contracts for oil, plastics, and resin are used to manage the Company's risk associated with the underlying commodity cost of a significant component used in packaging materials. Contracts for natural gas and electricity are used to manage the Company's risk associated with the utility costs of its manufacturing facilities, and other commodity contracts that are derivatives that do not meet the normal purchases and normal sales scope exception are used to manage the price risk associated with raw material costs. As of June 30, 2021, the Company had outstanding contracts for the purchase of 0.1 million megawatts of electricity, expiring throughout 2021 and 2022; 8.0 million gallons of diesel, expiring throughout 2021; 5.2 million dekatherms of natural gas, expiring throughout 2021 and 2022; 2.2 million pounds of coffee, expiring throughout 2021; 12.3 million pounds of resin, expiring throughout 2021 and 2022, and 0.4 million bushels of flour, expiring throughout 2021. Total Return Swap Contract - In March 2021, the Company entered into an economic hedge program that uses a total return swap contract to hedge the market risk associated with the unfunded portion of the Company's deferred compensation liability. The total return swap contract trades generally have a duration of one month and are rebalanced and re-hedged at the end of each monthly term. While the total return swap contract is treated as an economic hedge, the Company has not designated it as a hedge for accounting purposes. The total return swap contract is measured at fair value and recognized in the Condensed Consolidated Balance Sheets, with changes in value being recognized in the Condensed Consolidated Statements of Operations. As of June 30, 2021, the notional value of the total return swap contract was $7.2 million. The following table identifies the fair value of each derivative instrument: June 30, 2021 December 31, 2020 (In millions) Asset derivatives Commodity contracts $ 17.1 $ 12.6 Total return swap contract 0.1 — $ 17.2 $ 12.6 Liability derivatives Commodity contracts $ — $ 0.7 Foreign currency contracts 0.8 — Interest rate swap agreements 74.0 97.4 $ 74.8 $ 98.1 Asset derivatives are included within Prepaid expenses and other current assets and liability derivatives are included within Accrued expenses in the Condensed Consolidated Balance Sheets. The fair values of the commodity contracts, foreign currency contracts, interest rate swap agreements, and the total return swap contract are determined using Level 2 inputs. Level 2 inputs are inputs other than quoted market prices that are observable for an asset or liability, either directly or indirectly. The fair values of the commodity contracts, foreign currency contracts, interest rate swap agreements, and total return swap contract are based on an analysis comparing the contract rates to the market rates at the balance sheet date.

Segment Reporting [Abstract]
Segment Information	17. SEGMENT INFORMATION The Company manages operations on a company-wide basis, thereby making determinations as to the allocation of resources in total rather than on a segment-level basis. The Company has designated reportable segments based on how management views its business. The Company does not segregate assets between segments for internal reporting. Therefore, asset-related information has not been presented. The reportable segments, as presented below, are consistent with the manner in which the Company reports its results to the Chief Operating Decision Maker. The principal products that comprise each segment are as follows: Meal Preparation – Our Meal Preparation segment sells aseptic cheese & pudding; baking and mix powders; hot cereals; jams, preserves, and jellies; liquid and powdered non-dairy creamer; macaroni and cheese; mayonnaise; Mexican, barbeque, and other sauces; pasta; pickles and related products; powdered soups and gravies; refrigerated and shelf stable dressings and sauces; refrigerated dough; single serve hot beverages; skillet dinners; and table and flavored syrups. Snacking & Beverages – Our Snacking & Beverages segment sells bars; broths; candy; cookies; crackers; in-store bakery products; pita chips; powdered drinks; pretzels; ready-to-drink coffee; retail griddle waffles, pancakes, and French toast; specialty teas; and sweeteners. The Company evaluates the performance of its segments based on net sales dollars and direct operating income. Direct operating income is defined as gross profit less freight out, sales commissions, and direct selling, general, and administrative expenses. The amounts in the following tables are obtained from reports used by senior management and do not include income taxes. Other expenses not allocated include unallocated selling, general, and administrative expenses, unallocated costs of sales, and unallocated corporate expenses (amortization expense, other operating expense, and asset impairment). The accounting policies of the Company's segments are the same as those described in the summary of significant accounting policies set forth in Note 1 to the Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended December 31, 2020.
