Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation — The Consolidated Financial Statements include the accounts of TreeHouse Foods, Inc. and its 100% owned direct and indirect subsidiaries (the "Company," "TreeHouse,” "we," "us," or "our"). All intercompany balances and transactions are eliminated in consolidation. Discontinued Operations — Beginning in the third quarter of 2019, the Company determined that both its Snacks division and its Ready-to-eat ("RTE") Cereal business met the discontinued operations criteria in Accounting Standards Codification ("ASC") 205-20-45 and were classified as discontinued operations. As such, both businesses have been excluded from continuing operations and segment results for all periods presented. Refer to Note 7 for additional information. Use of Estimates — The preparation of our Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to use judgment to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the Consolidated Financial Statements, and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from these estimates. Cash and Cash Equivalents — We consider temporary cash investments with an original maturity of three months or less to be cash equivalents. As of December 31, 2021 and 2020, $39.3 million and $92.3 million, respectively, represents cash and cash equivalents held in foreign jurisdictions, in local currencies. The Company is exposed to potential risks associated with its cash and cash equivalents. The Company places its cash and cash equivalents with high credit quality financial institutions. Deposits with these financial institutions may exceed the amount of insurance provided; however, these deposits typically are redeemable upon demand and, therefore, the Company believes the financial risks associated with these financial instruments are minimal. Accounts Receivable — We provide credit terms to customers in-line with industry standards, perform ongoing credit evaluations of our customers, and maintain allowances for potential credit losses based on historical experience. Customer balances are written off after all collection efforts are exhausted. Estimated product returns, which have not been material, are deducted from sales at the time of shipment. Inventories — Inventories are stated at the lower of cost or net realizable value. We value inventories using the standard cost method which approximates costs determined on the first-in first-out basis. The costs of finished goods inventories include raw materials, labor, and overhead costs. Leases — Right-of-use assets and their corresponding lease liabilities are measured and recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. The Company does not record leases with an initial term of 12 months or less on the balance sheet. Expense for these short-term leases is recognized on a straight-line basis over the lease term. The majority of the Company's leases do not provide an implicit rate; therefore, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments for those leases. The Company has elected the practical expedient to apply discount rates to its lease portfolio based on the portfolio approach. The Company grouped the leases into portfolios by remaining lease term. The Company includes lease payments under options to extend or terminate the lease in the measurement of the right-of-use asset and lease liability when it is reasonably certain that it will exercise such options. For operating leases, lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Finance leases are amortized over the shorter of their lease term or their estimated useful lives, and amortization expense is included in depreciation expense. Fixed lease costs represent the explicitly quantified lease payments prescribed by the lease agreement and are included in the measurement of the right-of-use asset and corresponding lease liability. Variable lease payments that depend on an index or a rate are included in the calculation of the right-of-use asset and lease liability based on the index or rate at lease commencement. Other variable lease payments such as those that depend on the usage or performance of an underlying asset are not included in the measurement of the right-of-use asset or lease liability. The Company has elected the practical expedient to combine lease and nonlease components into a single component for all of its leases. Property, Plant, and Equipment — Property, plant, and equipment are stated at acquisition cost, plus capitalized interest on borrowings during the actual construction period of major capital projects. Depreciation and amortization are calculated using the straight-line method over the estimated useful lives of the assets as follows: Asset Useful Life Buildings and improvements 12-40 years Machinery and equipment 3-15 years Office furniture and equipment 3-12 years Building and leasehold improvements are depreciated over the shorter of the estimated useful life of the assets or the remaining useful life of the associated building or lease. We perform impairment tests when circumstances indicate that the carrying value of an asset may not be recoverable. Refer to Note 8 for additional information. Expenditures for repairs and maintenance, which do not improve or extend the life of the assets, are expensed as incurred. Intangible and Other Assets — Identifiable intangible assets with finite lives are amortized over their estimated useful lives as follows: Asset Useful Life Customer-related 5 to 20 years Trademarks 10 to 20 years Non-competition agreements Based on the terms of the agreements Deferred financing costs associated with line-of-credit arrangements Based on the terms of the agreements Formulas/recipes 5 to 7 years Computer software 3 to 10 years All amortization expense related to intangible assets is recorded in Amortization expense in the Consolidated Statements of Operations. Indefinite lived trademarks are evaluated for impairment annually in the fourth quarter or more frequently, if events or changes in circumstances indicate that the asset might be impaired. Impairment is indicated when their book value exceeds fair value. If the fair value of an evaluated asset is less than its book value, the asset is written down to fair value, which is generally based on its discounted future cash flows. Amortizable intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If an evaluation of the undiscounted cash flows indicates impairment, the asset group is impaired to its estimated fair value, which is generally based on discounted future cash flows, and the impairment is allocated to the individual assets within the asset group. Goodwill is evaluated annually in the fourth quarter or more frequently, if events or changes in circumstances require an interim assessment. We assess goodwill for impairment (as of December 31) at the reporting unit level using income and market approaches, employing significant assumptions regarding growth, discount rates, and profitability at each reporting unit. Our estimates under the income approach are determined based on a discounted cash flow model. The market approach uses a market multiple methodology employing earnings before interest, taxes, depreciation, and amortization ("EBITDA") and applies a range of multiples to those amounts in determining the indicated fair value. In determining the multiples used in this approach, we obtain the multiples for selected peer companies using the most recent publicly available information. In determining the indicated fair value of each reporting unit, the Company concludes based on the income approach, and uses the market approach to corroborate, as the Company believes the income approach is the most reliable indicator of the fair value of the reporting units. The resulting value is then compared to the carrying value of each reporting unit to determine if impairment is necessary. Revenue Recognition — We manufacture and sell food and beverage products to retailers, foodservice distributors, co-manufacturers, and industrial and export channels. Revenue recognition is completed on a point in time basis when product control is transferred to the customer. In general, control transfers to the customer when the product is shipped or delivered to the customer based upon applicable shipping terms. For each contract, the Company considers the transfer of products, each of which is distinct, to be the identified performance obligation generally satisfied within one year. No payment terms beyond one year are granted at contract inception. Most contracts also include some form of variable consideration. The most common forms of variable consideration include discounts, rebates, and sales returns and allowances. Variable consideration is treated as a reduction in revenue when product revenue is recognized. Depending on the specific type of variable consideration, we use either the expected value or most likely amount method to determine the variable consideration. The Company reviews and updates its estimates and related accruals of variable consideration each period based on the terms of the agreements, historical experience, and any recent changes in the market. The Company does not have significant deferred revenue or unbilled receivable balances arising from transactions with customers. We do not capitalize contract inception costs, as contracts are one year or less. The Company does not incur significant fulfillment costs requiring capitalization. Shipping and handling costs associated with outbound freight are included within Selling and distribution expenses and are accounted for as a fulfillment cost as incurred, including shipping and handling costs after control over a product has transferred to a customer. Shipping and handling costs recorded as a component of Selling and distribution expense were approximately $173.5 million, $153.6 million, and $148.3 million for the years ended December 31, 2021, 2020, and 2019, respectively. In addition, any taxes collected on behalf of government authorities are excluded from net sales. Cost of Sales — Cost of sales represents costs directly related to the manufacture and distribution of our products. Such costs include raw materials, packaging, direct and indirect labor, shipping and handling costs, and overhead which includes depreciation of manufacturing and distribution facilities. Shipping and handling costs included in cost of sales reflect inbound freight, inventory warehouse costs, product loading and handling costs, and costs associated with transporting finished products from our manufacturing facilities to distribution warehouses. Stock-Based Compensation — We measure compensation expense for our equity awards at their grant date fair value. The resulting expense is recognized over the relevant service period. Employment-Related Benefits — We provide a range of benefits to our employees, including pension and postretirement benefits to our eligible employees and retirees. We record annual amounts relating to these plans based on calculations specified by GAAP, which include various actuarial assumptions, such as discount rates, assumed investment rates of return, compensation increases, employee turnover rates, and health care cost trend rates. We make modifications to the actuarial assumptions based on plan changes, current rates, and trends when appropriate. Workers' Compensation — The measurement of the liability for our cost of providing these benefits is largely based upon loss development factors that contemplate a number of variables, including claims history and expected trends. These loss development factors are based on industry factors and, along with the estimated liabilities, are developed by us in consultation with external insurance brokers and actuaries. Changes in loss development factors, claims history, and cost trends could result in substantially different results in the future. Income Taxes — The provision for income taxes includes federal, foreign, state, and local income taxes currently payable, and those deferred because of temporary differences between the financial statement and tax bases of assets and liabilities. Deferred tax assets or liabilities are computed based on the difference between the financial statement and income tax bases of assets and liabilities using enacted tax rates. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Deferred income tax expenses or credits are based on the changes in the asset or liability from period to period. We account for uncertain tax positions using a "more-likely-than-not" threshold. A tax benefit from an uncertain tax position is recognized if it is more-likely-than-not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position, or the statute of limitations concerning such issues lapses. 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. All derivatives are recorded on a gross basis and carried at fair value in our Consolidated Balance Sheets. None of the Company's derivative instruments are accounted for under hedge accounting and the changes in their fair value are recorded in the Consolidated Statements of Operations. Foreign Currency Translation and Transactions — The functional currency of the Company’s foreign operations is the applicable local currency. The functional currency is translated into U.S. dollars for balance sheet accounts using currency exchange rates in effect as of the balance sheet date, and for revenue and expense accounts using a weighted-average exchange rate during the fiscal year. The translation adjustments are deferred as a separate component of Stockholders’ equity in Accumulated other comprehensive loss. Gains or losses resulting from transactions denominated in foreign currencies and intercompany debt that is not of a long-term investment nature are included in Gain on foreign currency exchange in the Consolidated Statements of Operations. Gains or losses resulting from intercompany debt that is designated a long-term investment are recorded as a separate component of Stockholders' equity in Accumulated other comprehensive loss. Restructuring Expenses — Restructuring charges principally consist of retention, severance, and other employee separation costs, contract termination costs, accelerated depreciation, professional fees, and certain long-lived asset impairments. The Company recognizes restructuring obligations and liabilities for exit and disposal activities at fair value in the period the liability is incurred. One-time employee termination benefits for employee severance costs are expensed evenly starting at the communication date over the period during which the employee is required to render service to receive the severance. Ongoing benefit arrangements for employee severance costs are expensed when they become probable and reasonably estimable. Depreciation expense related to assets that will be disposed of or idled as a part of the restructuring activity is accelerated through the expected date of the asset shut down.

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 which primarily reside in our Snacking & Beverages segment. 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 customers' 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 and retention. (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 and cost reduction, develop a lean customer-centric go-to-market team, centralize our supply chain, and streamline 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. Under the Structure to Win program, the Company reduced its Corporate office space in Oak Brook, Illinois and completed the closure of its St. Louis, Missouri Corporate office during the fourth quarter of 2020 and the second quarter of 2019, respectively. (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. The key information regarding the Company's completed plant closures during the periods presented are as follows: The Company completed the closure of its Visalia, California Pretzels facility within the Snacking & Beverages segment in the first quarter of 2019. Total costs to close this facility were $22.1 million and are classified within Other operating expense, net in the Consolidated Statements of Operations. Additionally, the Company completed the closure of its Omaha, Nebraska Corporate office during the first quarter of 2019. Expenses associated with the Company's Battle Creek, Michigan and Minneapolis, Minnesota 2019 facility closures are classified within Net income (loss) from discontinued operations. Total costs to close these two facilities were $17.9 million. Refer to Note 7 for additional information. (4) Other Other costs include restructuring costs incurred for costs to exit facilities, information technology system implementation, retention, severance, and other administrative costs. During the fourth quarter of 2021, the Company announced one-time employee recognition payments to drive retention for all incentive-eligible participants who remain actively employed until payment in the first quarter of 2022. The expense for these payments is recognized ratably through the required service period and the total estimated expense is $15.2 million. In the fourth quarter of 2021, $8.1 million was recognized in other costs and included as a liability within Accrued expenses in the Consolidated Balance Sheets as of December 31, 2021. The remaining expense is expected to be recognized in the first quarter of 2022. An additional $1.6 million of other retention liabilities was recognized primarily for employees in connection with the ongoing, Board-led strategic review and is included within Accrued expenses in the Consolidated Balance Sheets as of December 31, 2021. The costs by activity for the Growth, Reinvestment, and Restructuring Programs are outlined below: Year Ended December 31, 2021 2020 2019 (In millions) Strategic Growth Initiatives $ 57.8 $ — $ — Structure to Win — 32.7 15.9 TreeHouse 2020 — 40.5 89.5 Other 29.3 — — Total $ 87.1 $ 73.2 $ 105.4 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 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 21 for additional information. Below is a summary of costs by line item for the Growth, Reinvestment, and Restructuring Programs: Year Ended December 31, 2021 2020 2019 (In millions) Cost of sales $ — $ 0.9 $ 4.4 General and administrative — 1.2 1.7 Other operating expense, net 87.1 71.1 99.3 Total $ 87.1 $ 73.2 $ 105.4 Below is a summary of costs by type associated with the Growth, Reinvestment, and Restructuring Programs: Year Ended December 31, 2021 2020 2019 (In millions) Asset-related $ — $ 0.2 $ 4.7 Employee-related 28.9 13.5 15.6 Other costs 58.2 59.5 85.1 Total $ 87.1 $ 73.2 $ 105.4 For the years ended December 31, 2021, 2020, and 2019, asset-related costs primarily consisted of accelerated depreciation; employee-related costs primarily consisted of dedicated project employee cost, severance, and retention; and other costs primarily consisted of consulting services. Asset-related costs are primarily recognized in Cost of sales while employee-related and other costs are primarily recognized in Other operating expense, net in the Consolidated Statements of Operations.

Receivables [Abstract]
Receivables Sales Program	5. RECEIVABLES SALES PROGRAM The Company has entered into agreements to sell certain trade accounts receivable to unrelated, third-party financial institutions at a discount (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 outstanding accounts receivables sold at any time is $500.0 million. The following table includes the outstanding amount of accounts receivable sold under the Receivables Sales Program and the receivables collected from customers and not remitted to the financial institutions: December 31, 2021 2020 (In millions) Outstanding accounts receivable sold $ 357.3 $ 284.3 Receivables collected and not remitted to financial institutions 205.0 202.8 Receivables sold under the Receivables Sales Program are derecognized from the Company's Consolidated Balance Sheet at the time of the sale and the proceeds from such sales are reflected as a component of the change in receivables in the operating activities section of the Consolidated Statements of Cash Flows. The receivables collected and not remitted to financial institutions are included in Accounts payable in the Consolidated Balance Sheets. The following table summarizes the cash flows of the Company's accounts receivables associated with the Receivables Sales Program: Year Ended December 31, 2021 2020 2019 (In millions) Receivables sold $ 1,846.9 $ 1,185.1 $ 1,114.1 Receivables collected and remitted to financial institutions (1,773.9) (1,143.8) (1,048.0) The loss on sale of receivables represents the discount taken by third-party financial institutions and was $2.4 million, $2.4 million, and $4.3 million for the years ended December 31, 2021, 2020, and 2019, respectively, and is included in Other (income) expense, net in the Consolidated Statements of Operations. The Company has not recognized any servicing assets or liabilities as of December 31, 2021 or December 31, 2020, as the fair value of the servicing arrangement as well as the fees earned were not material to the financial statements.

Business Combination and Asset Acquisition [Abstract]
Acquisitions and Divestitures	7. 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 $1.5 million and property, plant, and equipment, net at $3.6 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. Included in the Company’s Consolidated Statements of Operations are the pasta acquisition’s net sales of approximately $11.6 million and loss before income taxes of $(0.9) million from the date of acquisition through December 31, 2020. The Company incurred approximately $6.3 million in acquisition-related costs in 2020. These costs are included in General and administrative expense of the Consolidated Statements of Operations. The following table summarizes the final 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 50.7 Customer relationships 68.0 Trade names 43.0 Formulas/recipes 2.3 Goodwill 60.4 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 and expensed $1.0 million and $2.1 million as a component of Cost of sales during the year ended December 31, 2021 and 2020, respectively, for the amortization of the inventory step up adjustment. The Company allocated $60.4 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 Company recorded measurement period adjustments which increased goodwill and decreased property, plant, and equipment, net by $1.1 million during the second quarter of 2021 related to the original consideration and $0.2 million during the third quarter of 2021 related to the call option exercised. 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, the amortization of the inventory fair value step-up, acquisition-related costs, and related income taxes. Excluded from the 2020 pro forma results are $6.3 million of acquisition-related costs incurred by the Company in connection with the acquisition as they have been included in the 2019 pro forma results. 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. Year Ended December 31, 2020 2019 (Unaudited, in millions) Pro forma net sales from continuing operations $ 4,550.4 $ 4,454.1 Pro forma net income (loss) from continuing operations 83.4 (106.3) Refrigerated Dough Acquisition On September 1, 2020, the Company completed an acquisition of a refrigerated dough business for a purchase price of $17.5 million, which included the recognition of $10.7 million of goodwill within the Meal Preparation segment. Discontinued Operations Ready-to-eat Cereal On June 1, 2021, the Company simultaneously entered into a definitive agreement and completed the sale of its Ready-to-eat ("RTE") Cereal business to Post Holdings, Inc. ("Post") for a base purchase price of $85.0 million, subject to customary purchase price adjustments, resulting in cash proceeds at closing of $88.0 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 (loss) from discontinued operations in the 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. A third plant in Battle Creek, Michigan was not included with the sale and closed in 2019. 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 year ended December 31, 2021 and is primarily classified within General and administrative expenses or Cost of sales in the Company's Consolidated Statements of Operations depending on the functions being supported by the Company. Prior to the sale of the RTE Cereal business, there were expected disposal loss adjustments of $0.3 million, $51.2 million, and $74.5 million recognized as asset impairment charges during the years ended December 31, 2021, 2020, and 2019, respectively, within Net income (loss) from discontinued operations. Snacks During the second quarter of 2019, due to changes in market price expectations for the sale of the Company's Snacks division, the Company assessed the recoverability of the carrying value of the long-lived assets associated with the division. This assessment resulted in total long-lived asset impairment losses of $66.5 million, comprised of $63.2 million of property, plant, and equipment impairment losses and $3.3 million of intangible asset impairment losses. These losses result from the estimated fair value of the Snacks asset group, which was determined by its estimated discounted cash flows. These cash flows represent Level 3 inputs under ASC 820. These impairment charges are included in Net income (loss) from discontinued operations in the Consolidated Statements of Operations. On August 1, 2019, the Company completed the sale of its Snacks division to Atlas Holdings, LLC. ("Atlas") for $90.0 million in cash, subject to customary purchase price adjustments. The Company classified the proceeds within Net cash provided by (used in) investing activities - discontinued operations and used the net proceeds of the sale to pay down debt. The Company recognized a non-cash pre-tax loss on the transaction upon closing of $98.4 million, which is recognized as a component of Net income (loss) from discontinued operations in the Consolidated Statements of Operations. For tax purposes, the sale has resulted in a capital loss of $586.2 million. As a result, we have established a deferred tax asset of $149.1 million. A full valuation allowance was recorded against the deferred tax asset as we have not met the accounting requirements for recognition of a benefit at this time. The sale of this business is part of the Company's portfolio optimization strategy. The Snacks division operated three plants located in Robersonville, North Carolina; El Paso, Texas; and Dothan, Alabama. A fourth plant in Minneapolis, Minnesota was not included with the sale and closed during the third quarter of 2019. The Company entered into a Transition Services Agreement ("TSA") with Atlas, which was designed to ensure and facilitate an orderly transfer of business operations. The services provided under the TSA terminated August 1, 2020. The income received under the TSA was not material for the years ended December 31, 2020 and 2019 and is primarily classified within General and administrative expenses or Cost of sales in the Company's Consolidated Statements of Operations depending on the functions being supported by the Company. The Company has reflected the RTE Cereal business and Snacks division (through the dates of sale) as discontinued operations for all periods presented. Unless otherwise noted, amounts and disclosures throughout these Notes to Consolidated Financial Statements relate to the Company's continuing operations.

These two facilities were included within the Snacking & Beverages reporting segment. These two facilities did not meet the criteria to be presented as a discontinued operation. On April 17, 2020, the sale of these facilities was completed for $26.9 million. The cash proceeds were classified within Net cash used in investing activities - continuing operations. The Company recognized a loss upon divestiture of $0.3 million within Other operating expense, net in the Consolidated Statements of Operations during the year ended December 31, 2020. During the year ended December 31, 2019, the disposal group was measured at fair value prior to the sale, and the Company recognized the expected disposal loss as an impairment charge of $41.1 million recognized within Asset impairment in the Consolidated Statements of Operations.

Asset Impairment We evaluate property, plant, and equipment, operating lease right-of-use assets, and finite lived intangible assets for impairment when circumstances indicate that their carrying values may not be recoverable. Indicators of impairment include deteriorations in operating cash flows, the anticipated sale or disposal of an asset group, and other significant changes in business conditions. During the fourth quarter of 2021, as a result of rising input costs coupled with lower than expected new business wins, we revised our forecast expectations for the Bars asset group and performed a recoverability assessment. Our assessment indicated that the Bars asset group was not recoverable, and we were required to determine the fair value of the business. Our fair value assessment indicated that the carrying value was in excess of the fair value, and an impairment of $9.2 million of property, plant, and equipment was recognized in our Bars asset group, within the Snacking & Beverages segment. The impairment charge is included in Asset impairment in the Consolidated Statements of Operations. During 2019, our assessment indicated an impairment in our Cookies and Dry Dinners asset groups, within the Snacking & Beverages and Meal Preparation segments, respectively, driven by the historical and forecasted performance of these businesses. As a result, we recognized $42.8 million of property, plant, and equipment impairment losses and $45.2 million of finite lived intangible asset impairment. The impairment charges are included in Asset impairment in the Consolidated Statements of Operations. Impairment charges are measured by comparing the carrying values of the asset groups to their estimated fair values. The fair value of these assets were based on expected future cash flows using Level 3 inputs under ASC 820. We can provide no assurance regarding the prospect of additional impairment charges in future periods.

In addition, as described in Note 7, the Company has recorded a full valuation allowance against the deferred tax asset of $149.1 million it established for its capital loss resulting from the sale of the Snacks division. The Company or one of its subsidiaries files income tax returns in the U.S., Canada, Italy, the Netherlands, and various U.S. states. In the U.S. federal jurisdiction, the Company is open to examination for the tax years ended December 31, 2014 through December 31, 2016 and December 31, 2018 and forward; for Canadian purposes, the Company is open to examination for the tax year ended December 31, 2012 and forward; for Italian purposes, the Company is open to examination for the tax years ended December 31, 2016 and forward; and for the various U.S. states the Company is generally open to examination for the tax year ended December 31, 2017 and forward. The Internal Revenue Service ("IRS") is currently examining the TreeHouse Foods, Inc. & Subsidiaries’ 2019 and 2020 tax years. Our Canadian operations are under exam by the Canadian Revenue Agency ("CRA") for tax years 2012 through 2018. These examinations are expected to be completed in 2022. The Company has examinations in process with various state taxing authorities, which are expected to be completed in 2022. During the year, the Company recorded adjustments to its unrecognized tax benefits. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: Year Ended December 31, 2021 2020 2019 (In millions) Unrecognized tax benefits beginning balance $ 10.7 $ 12.3 $ 17.3 Additions (reductions) based on tax positions of prior years 0.5 2.4 (1.1) Reductions resulting from dispositions — — (1.1) Reductions due to statute lapses (4.1) (3.4) (2.8) Reductions related to settlements with taxing authorities — (0.7) (0.1) Foreign currency translation — 0.1 0.1 Unrecognized tax benefits ending balance $ 7.1 $ 10.7 $ 12.3 Unrecognized tax benefits are included in Other long-term liabilities of the Consolidated Balance Sheets. Of the amount accrued at December 31, 2021 and 2020, $4.4 million and $5.5 million, respectively, would impact Net (loss) income from continuing operations when settled. Of the amounts accrued at December 31, 2021 and 2020, $1.8 million and $4.8 million, respectively, relates to unrecognized tax benefits assumed in prior acquisitions, which have been indemnified by the previous owners. Management estimates that it is reasonably possible that the total amount of unrecognized tax benefits could decrease by as much as $1.0 million within the next 12 months, primarily as a result of the resolution of audits currently in progress and the lapsing of statutes of limitations. Approximately $0.9 million of the $1.0 million would affect net income when settled. The timing of cash settlement, if any, cannot be reasonably estimated for uncertain tax benefits. The Company recognizes interest expense (income) and penalties related to unrecognized tax benefits in income tax expense. During the years ended December 31, 2021, 2020, and 2019, the Company recognized $(1.3) million, $(1.4) million, and $(0.2) million of interest and penalties in income tax expense from continuing operations, respectively. The Company has accrued approximately $1.1 million and $2.4 million for the payment of interest and penalties at December 31, 2021 and 2020, respectively, of which $0.6 million and $1.7 million is indemnified. On March 27, 2020, the CARES Act was signed into law, which features several tax provisions and other measures that assist businesses impacted by the economic effects of the COVID-19 pandemic. The significant tax provisions include an increase in the limitation of the tax deduction for interest expense from 30% to 50% of adjusted earnings in 2019 and 2020, a five-year carryback allowance for net operating losses ("NOLs") generated in tax years 2018-2020, increased charitable contribution limitations to 25% of taxable income in 2020, and a retroactive technical correction to the 2017 Tax Cuts and Jobs Act that makes qualified improvement property placed in service after December 31, 2017 eligible for bonus depreciation. The Company has recorded a $1.9 million income tax expense and a $29.3 million income tax benefit related to the NOL carryback provisions of the CARES Act for the years ended December 31, 2021 and 2020, respectively.

As amended, the senior unsecured credit facility includes a revolving credit facility (the "Revolving Credit Facility" or the "Revolver") and two term loans. The Credit Agreement (1) extended the maturity dates of the Revolving Credit Facility, Term Loan A, and Term Loan A-1, (2) resized the Revolver from $900 million to $750 million, (3) consolidated three term loans into two, (4) tightened pricing, and (5) modified the fee structure on the Revolving Credit Facility to now calculate based on the unused portion of the commitments under the Revolving Credit Facility rather than the total commitments under the Revolving Credit Facility. The Credit Agreement has been amended as follows: • On June 11, 2018, the Company entered into Amendment No. 1 to the Credit Agreement. Under Amendment No. 1, among other things, (i) the leverage covenant threshold increased through fiscal year 2019, (ii) the Company and the other loan parties secured the obligations with liens on substantially all of their personal property, and (iii) such liens will be released upon the Company’s leverage ratio being less than or equal to 4.00 to 1.00 no earlier than the fiscal quarter ended on December 31, 2019. The material terms and conditions under the Credit Agreement are otherwise substantially consistent with those contained in the Credit Agreement prior to Amendment No. 1. • On August 26, 2019, the Company entered into Amendment No. 2 to the Credit Agreement. Amendment No. 2 permanently maintains the secured status of the credit facility and the maximum permitted leverage ratio at 4.5x. Absent Amendment No. 2, the Credit Agreement was scheduled to return to unsecured status with a maximum permitted leverage ratio of 4.0x in the fourth quarter of 2019. The material terms and conditions under the Credit Agreement are otherwise substantially consistent with those contained in the Credit Agreement prior to Amendment No. 2. • On March 26, 2021, the Company entered into Amendment No. 3 to the Credit Agreement among the Company, the other loan parties thereto, the lenders from time to time party thereto and Bank of America N.A., as administrative agent, swing line lender and L/C issuer. Under Amendment No. 3, among other things, the parties have agreed to: (i) amend and extend the maturity date of the Revolving Credit Facility and Tranche A-1 Term Loans until March 26, 2026 and the maturity date of the Term A Loans until March 26, 2028 (each as defined in the Credit Agreement), (ii) refinance the existing Term A Loans and increase the Tranche A-1 Term Loan amount to $930.0 million, and (iii) include customary provisions under Amendment No. 3 providing for the replacement of LIBOR with any successor rate. The material terms and conditions under the Credit Agreement are otherwise substantially consistent with those contained in the Credit Agreement prior to Amendment No. 3. • On February 14, 2022, the Company entered into Amendment No. 4 to the Credit Agreement. Amendment No.4 temporarily increases the leverage covenant threshold from 4.50x to 5.50x through June 30, 2022, then 5.25x through September 30, 2022 and thereafter reverts to 4.50x. The material terms and conditions under the Credit Agreement are otherwise substantially consistent with those contained in the Credit Agreement prior to Amendment No. 4. The Company’s average interest rate on debt outstanding under its Credit Agreement for the year ended December 31, 2021 was 1.68%. Including the impact of interest rate swap agreements in effect as of December 31, 2021, the average rate is 3.44%. Revolving Credit Facility — As of December 31, 2021, $730.1 million of the aggregate commitment of $750.0 million of the Revolving Credit Facility was available. Under the Credit Agreement, the Revolving Credit Facility matures on February 1, 2023. In addition, as of December 31, 2021, there were $19.9 million in letters of credit under the Revolving Credit Facility that were issued but undrawn, which have been included as a reduction to the calculation of available credit. Interest is payable quarterly or, if earlier, at the end of the applicable interest period in arrears on any outstanding borrowings under the Revolving Credit Facility. The interest rates applicable to the Revolving Credit Facility are based upon the Company’s consolidated net leverage ratio or the Company’s Corporate Credit Rating, whichever results in lower pricing, and are determined by either (i) LIBOR, plus a margin ranging from 1.20% to 1.70%, or (ii) a Base Rate (as defined in the Credit Agreement), plus a margin ranging from 0.20% to 0.70%. The unused fee on the Revolving Credit Facility is also based on the Company’s consolidated net leverage ratio or the Company’s Corporate Credit Rating, whichever results in lower pricing, and accrues at a rate ranging from 0.20% to 0.35%. The Credit Agreement is fully and unconditionally, as well as jointly and severally, guaranteed by our 100% owned direct and indirect domestic subsidiaries: Bay Valley Foods, LLC; Sturm Foods, Inc.; S.T. Specialty Foods, Inc.; Associated Brands, Inc.; TreeHouse Foods Services, LLC; Protenergy Holdings, Inc.; Protenergy Natural Foods, Inc.; TreeHouse Private Brands, Inc.; American Italian Pasta Company; Linette Quality Chocolates, Inc.; Ralcorp Frozen Bakery Products, Inc.; Cottage Bakery, Inc.; The Carriage House Companies, Inc. and certain other domestic subsidiaries that may become guarantors in the future, which are collectively known as the "Guarantor Subsidiaries." The Credit Agreement contains various financial and restrictive covenants and requires that the Company maintain a consolidated net leverage ratio of no greater than 4.50 to 1.0, with the exception of the temporary increase in Amendment No. 4. The Credit Agreement also contains cross-default provisions which could result in the acceleration of payments in the event TreeHouse or the Guarantor Subsidiaries (i) fails to make a payment when due in respect of any indebtedness or guarantee having an aggregate principal amount greater than $75.0 million or (ii) fails to observe or perform any other agreement or condition related to such indebtedness or guarantee as a result of which the holder(s) of such debt are permitted to accelerate the payment of such debt. Term Loan A — On December 1, 2017, the Company entered into a $500 million term loan which amended and extended the Company’s existing term A loan. Amendment No. 3 of the Credit Agreement extended the maturity date to March 26, 2028. The interest rates applicable to Term Loan A are based upon the Company’s consolidated net leverage ratio or the Company’s Corporate Credit Rating, whichever results in lower pricing, and are determined by either (i) LIBOR, plus a margin ranging from 1.675% to 2.175%, or (ii) a Base Rate (as defined in the Credit Agreement), plus a margin ranging from 0.675% to 1.175%. Principal amortization payments are due on a quarterly basis and interest is payable quarterly or, if earlier, at the end of the applicable interest period in arrears on any outstanding borrowings under Term Loan A. Term Loan A is subject to substantially the same covenants as the Revolving Credit Facility, and also has the same Guarantor Subsidiaries. Term Loan A-1 — On December 1, 2017, the Company entered into a term loan which amended and extended the Company’s existing tranche A-1 term loan. Amendment No. 3 of the Credit Agreement increased the loan amount to $930 million and extended the maturity date to March 26, 2026. The interest rates applicable to Term Loan A-1 are the same as those applicable to the Revolving Credit Facility (other than, for the avoidance of doubt, the unused fee). Principal amortization payments are due on a quarterly basis and interest is payable quarterly or, if earlier, at the end of the applicable interest period in arrears on any outstanding borrowing under Term Loan A-1. Term Loan A-1 is subject to substantially the same covenants as the Revolving Credit Facility, and has the same Guarantor Subsidiaries. 2024 Notes — The Company previously issued 6.000% notes in the aggregate principal amount of $775 million due on February 15, 2024 (the "2024 Notes"). On February 16, 2021 the Company, through Wells Fargo Bank, National Association, as trustee (the "Trustee"), completed a partial redemption of $200.0 million of its 2024 Notes, and on March 31, 2021, the Company completed the full redemption of the remaining $402.9 million outstanding principal of its 2024 Notes at a price of 101.50% of the principal amount, plus accrued and unpaid interest to, but not including, each redemption date (the "2024 Notes Redemption"). 2028 Notes — On September 9, 2020, the Company completed its public offering of $500 million aggregate principal amount of the 2028 Notes. The 2028 Notes pay interest at the rate of 4.000% per annum and mature on September 1, 2028. Interest is payable on the 2028 Notes on March 1 and September 1 of each year. The payments began on March 1, 2021. The Company may redeem some or all of the 2028 Notes at any time prior to September 1, 2023 at a price equal to 100% of the principal amount of the 2028 Notes redeemed plus an applicable "make-whole" premium and accrued and unpaid interest to the redemption date. On or after September 1, 2023, the Company may redeem some or all of the 2028 Notes at redemption prices set forth in the Indenture, plus accrued and unpaid interest to the redemption date. In addition, at any time prior to September 1, 2023, the Company may redeem up to 40% of the 2028 Notes at a redemption price of 104.000% of the principal amount of the 2028 Notes redeemed, plus accrued and unpaid interest to the redemption date, with the net cash proceeds of certain equity offerings. Subject to certain limitations, in the event of a change of control of the Company, the Company will be required to make an offer to purchase the 2028 Notes at a purchase price equal to 101% of the principal amount of the 2028 Notes, plus accrued and unpaid interest to the date of purchase. The Company issued the 2028 Notes pursuant to a single base Indenture among the Company, the Guarantor Subsidiaries, and the Trustee. The Indenture provides, among other things, that the 2028 Notes will be senior unsecured obligations of the Company. The Company’s payment obligations under the 2028 Notes are fully and unconditionally, as well as joint and severally, guaranteed on a senior unsecured basis by the Guarantor Subsidiaries, in addition to any future domestic subsidiaries that guarantee or become borrowers under its credit facility or guarantee certain other indebtedness incurred by the Company or its restricted subsidiaries. The Indenture governing the 2028 Notes contains customary event of default provisions (including, without limitation, defaults relating to the failure to pay at final maturity or the acceleration of certain other indebtedness). If an event of default occurs and is continuing, the trustee under the Indenture or holders of at least 25% in principal amount of such notes may declare the principal amount and accrued and unpaid interest, if any, on all such notes to be due and payable. The Indenture also contains restrictive covenants that, among other things, limit the ability of the Company and the Guarantor Subsidiaries to: (i) incur additional indebtedness and issue certain preferred shares, (ii) make certain distributions, investments and other restricted payments, (iii) sell certain assets, (iv) agree to restrictions on the ability of restricted subsidiaries to make payments to the Company, (v) create liens, (vi) merge, consolidate or sell substantially all of the Company’s assets (vii) enter into certain transactions with affiliates, and (viii) engage in certain sale and leaseback transactions. The foregoing limitations are subject to exceptions as set forth in the Indenture. In addition, if in the future, the 2028 Notes have an investment grade credit rating by both Moody’s Investors Services, Inc. and Standard & Poor’s Ratings Services, certain of these covenants will, thereafter, no longer apply to the 2028 Notes for so long as the 2028 Notes are rated investment grade by the two rating agencies. Loss on Extinguishment of Debt — During the year ended December 31, 2021, the Company incurred a loss on extinguishment of debt totaling $14.4 million, which included a premium of $9.0 million and a write off of deferred financing costs of $5.4 million in connection with the 2024 Notes Redemption and Credit Agreement refinancing. During the year ended December 31, 2020, the Company incurred a loss on extinguishment of debt totaling $1.2 million representing the write-off of deferred financing costs in connection with the redemption of its 2022 Notes completed on September 25, 2020. Interest Rate Swap Agreements — As of December 31, 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. The swaps cover a period through February 28, 2025. Fair Value — At December 31, 2021, the aggregate fair value of the Company's total debt was $1,899.5 million and its carrying value was $1,919.3 million. At December 31, 2020, the aggregate fair value of the Company's total debt was $2,250.4 million and its carrying value was $2,228.9 million. The fair values of Term Loan A and Term Loan A-1 were estimated using present value techniques and market-based interest rates and credit spreads. The fair value of the Company's 2024 and 2028 Notes was estimated based on quoted market prices for similar instruments due to their infrequent trading volume. Accordingly, the fair value of the Company's debt is classified as Level 2 within the valuation hierarchy. Finance Lease Obligations and Other — The Company owes $3.1 million related to finance leases. Finance lease obligations represent machinery and equipment financing obligations, which are payable in monthly installments of principal and interest, and are collateralized by the related assets financed. Refer to Note 4 for additional information regarding the Company's finance leases. Deferred Financing Costs — As of December 31, 2021 and December 31, 2020, deferred financing costs of $16.1 million and $18.3 million were included as a direct deduction from outstanding long-term debt. Fees associated with the Revolving Credit Facility are presented in Other assets, net.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	15. STOCK-BASED COMPENSATION The Board of Directors adopted, and the Company’s Stockholders approved, the "TreeHouse Foods, Inc. Equity and Incentive Plan" (the "Plan"). 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 authorized to be awarded under the Plan is approximately 17.5 million, of which approximately 3.8 million remained available at December 31, 2021. Total compensation expense related to stock-based payments and the related income tax benefit recognized in Net (loss) income from continuing operations are as follows: Year Ended December 31, 2021 2020 2019 (In millions) Compensation expense related to stock-based payments $ 15.6 $ 26.1 $ 22.6 Related income tax benefit 3.9 6.7 5.8 The Company estimates that certain key executives and all directors will complete the required service conditions associated with their awards. For all other employees, the Company estimates its forfeiture rate based on historical experience. All amounts below include continuing and discontinued operations. Stock Options — The following table summarizes stock option activity during 2021: Employee Weighted Weighted Aggregate (In thousands) (In millions) Outstanding, at January 1, 2021 1,312 $ 77.62 3.1 $ — Expired (163) 64.32 Outstanding, at December 31, 2021 1,149 79.51 2.3 — Vested/expected to vest, at December 31, 2021 1,149 79.51 2.3 — Exercisable, at December 31, 2021 1,149 79.51 2.3 — Year Ended December 31, 2021 2020 2019 (In millions) Intrinsic value of stock options exercised $ — $ 0.7 $ 0.1 Tax benefit recognized from stock option exercises — 0.2 — There are no future compensation costs related to unvested options at December 31, 2021. There were no options granted in 2021, 2020, or 2019. Stock options granted under the plan generally have a three year vesting schedule, vest one-third on each of the first three anniversaries of the grant date, and expire ten years from the grant date. Stock options are generally only granted to employees and non-employee directors. Restricted Stock Units — Employee restricted stock unit awards generally vest based on the passage of time in approximately three three three The following table summarizes the restricted stock unit activity during the year ended December 31, 2021: Employee Weighted Director Weighted (In thousands) (In thousands) Outstanding, at January 1, 2021 707 $ 47.92 125 $ 54.67 Granted 440 49.56 37 48.03 Vested (333) 46.96 (111) 55.38 Forfeited (154) 50.71 (1) 52.46 Outstanding, at December 31, 2021 660 48.88 50 48.15 Vested and deferred, at December 31, 2021 16 48.35 Year Ended December 31, 2021 2020 2019 (In millions) Fair value of vested restricted stock units $ 22.6 $ 11.1 $ 19.5 Tax benefit recognized from vested restricted stock units 3.8 2.0 3.7 Future compensation costs related to restricted stock units are approximately $22.3 million as of December 31, 2021 and will be recognized on a weighted average basis over the next 1.6 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. The assumptions used in the Monte Carlo simulation were as follows: Year Ended December 31, 2021 Dividend yield 0 % Risk-free rate 0.30 % Expected volatility 35.65 % Expected term (in years) 2.75 The following table summarizes the performance unit activity during the year ended December 31, 2021: Performance Weighted (In thousands) Unvested, at January 1, 2021 541 $ 52.38 Granted 166 52.80 Vested (105) 45.79 Forfeited (122) 55.10 Unvested, at December 31, 2021 480 54.21 Year Ended December 31, 2021 2020 2019 (In millions) Fair value of vested performance units $ 5.6 $ 3.3 $ 0.9 Tax benefit recognized from performance units vested 0.3 0.7 0.2

Retirement Benefits [Abstract]
Employee Pension and Postretirement Benefit Plans	17. EMPLOYEE PENSION AND POSTRETIREMENT BENEFIT PLANS Defined Contribution Plans — Certain of our union and non-union employees participate in savings and profit sharing plans. These plans generally provide for salary reduction contributions to the plans on behalf of the participants of between 1% and 80% of a participant’s annual compensation and provide for employer matching and profit sharing contributions. The Company established a tax-qualified defined contribution plan to manage the assets. On a continuing operations basis, for the years ended December 31, 2021, 2020, and 2019, the Company made matching and profit sharing contributions to the plans of $20.7 million, $20.4 million, and $19.4 million, respectively. Pension and Postretirement Benefits — Certain employees and retirees participate in pension and other postretirement benefit plans. Employee benefit plan obligations and expenses included in the Consolidated Financial Statements are determined based on plan assumptions, employee demographic data, including years of service and compensation, benefits and claims paid, and employer contributions. The information below includes the activities of the Company's continuing and discontinued operations. Pension benefits for eligible salaried and non-union employees were frozen in 2002 for years of creditable service. For these employees, incremental pension benefits are only earned for changes in compensation affecting final average pay. Pension benefits earned by union employees covered by collective bargaining agreements, but not participating in multiemployer pension plans, are earned based on creditable years of service and the specified benefit amounts negotiated as part of the collective bargaining agreements. The Company’s funding policy provides that annual contributions to the pension plan master trust will be at least equal to the minimum amounts required by Employee Retirement Income Security Act of 1974, as amended. The Company estimates that its 2022 contributions to its pension plans will be $0.7 million. The measurement date for the defined benefit pension plans is December 31. Certain employees participate in benefit programs that provide certain health care and life insurance benefits for retired employees and their eligible dependents. The plans are unfunded. The Company estimates that its 2022 contributions to its postretirement benefit plans will be $1.5 million. The measurement date for the other postretirement benefit plans is December 31. The Company established a tax-qualified pension plan and master trust to manage the portion of the pension plan assets related to eligible salaried, non-union, and union employees not covered by a multiemployer pension plan. We also retain investment consultants to assist our Investment Committee with formulating a long-term investment policy for the master trust. The expected long-term rate of return on assets is based on projecting long-term market returns for the various asset classes in which the plan’s assets are invested, weighted by the target asset allocations. The estimated ranges are primarily based on observations of historical asset returns and their historical volatility. In determining the expected returns, we also consider consensus forecasts of certain market and economic factors that influence returns, such as inflation, gross domestic product trends, and dividend yields. Active management of the plan assets may result in adjustments to the historical returns. We review the rate of return assumption annually. Our investment objectives are to minimize the volatility of the value of our pension assets relative to our pension liabilities and to ensure assets are sufficient to pay plan benefits. We have a broad pension de-risking strategy intended to align the characteristics of our assets relative to our liabilities. The strategy targets investments depending on the funded status of the obligation. We anticipate this strategy will continue in future years and will be dependent upon market conditions and plan characteristics. At December 31, 2021, our master trust was invested as follows: investments in equity securities were at 40%; investments in fixed income were at 53%; investments in hedge funds were at 6%; and cash and cash equivalents were less than 1%. The allocation of our master trust investments as of December 31, 2021 is generally consistent with the targets set forth by our Investment Committee. The fair value of the Company’s pension plan assets at December 31, 2021 and 2020 is as follows: December 31, Pricing Category 2021 2020 (In millions) Cash and cash equivalents (a) Level 1 $ 1.5 $ 1.6 Investments valued using NAV per share: Equity funds (b) 129.7 137.3 Fixed income funds (c) 173.4 170.2 Alternative funds (d) 18.7 16.8 Total plan assets $ 323.3 $ 325.9 (a) Includes cash and cash equivalents such as short-term marketable securities. Cash and cash equivalents include money market funds traded in active markets. (b) This investment class includes domestic and international equity funds that includes both large and small/mid cap funds that track the S&P index as well as other equity indices. The Company elected the NAV practical expedient to value these funds. (c) This investment class includes U.S. Treasury index funds as well as bond funds representative of the United States bond and debt markets with varying benchmark indices. The Company elected the NAV practical expedient to value these funds. (d) This investment class primarily includes a hedge fund. The valuation is based on NAV as reported by the asset manager or investment company and adjusted for cash flows, if necessary. In making such an assessment, a variety of factors are reviewed by management, including but not limited to the timeliness of NAV as reported by the asset manager and changes in general economic and market conditions subsequent to the last NAV reported by the asset manager. The following table summarizes information about our pension and postretirement benefit plans for the years ended December 31, 2021 and 2020: Pension Benefits Postretirement 2021 2020 2021 2020 (in millions) Change in projected benefit obligation: Projected benefit obligation, at beginning of year $ 355.1 $ 336.0 $ 26.1 $ 27.5 Service cost 1.0 1.8 — — Interest cost 8.8 10.5 0.7 0.8 Curtailment (1) (0.7) — (0.4) — Actuarial (gains) losses (2) (14.2) 24.9 (1.6) (0.7) Benefits paid (19.1) (18.1) (1.5) (1.5) Projected benefit obligation, at end of year $ 330.9 $ 355.1 $ 23.3 $ 26.1 Change in plan assets: Fair value of plan assets, at beginning of year $ 325.9 $ 294.0 $ — $ — Actual gain on plan assets 15.8 48.5 — — Company contributions 0.7 1.5 1.5 1.5 Benefits paid (19.1) (18.1) (1.5) (1.5) Fair value of plan assets, at end of year $ 323.3 $ 325.9 $ — $ — Funded status of the plan $ (7.6) $ (29.2) $ (23.3) $ (26.1) Amounts recognized in the Consolidated Balance Sheets: Noncurrent asset $ 2.6 $ — $ — $ — Current liability (0.7) (0.7) (1.5) (1.5) Noncurrent liability (9.5) (28.5) (21.8) (24.6) Net amount recognized $ (7.6) $ (29.2) $ (23.3) $ (26.1) Amounts recognized in Accumulated other Net actuarial gain $ (20.5) $ (3.9) $ (2.6) $ (0.9) Prior service cost 0.2 0.4 — — Total, before tax effect $ (20.3) $ (3.5) $ (2.6) $ (0.9) (1) Curtailment relates to the sale of the RTE Cereal business.

These plans are administered jointly by management and union representatives and cover substantially all full-time and certain part-time union employees who are not covered by other plans. The risks of participating in multiemployer plans are different from single-employer plans in the following aspects: (1) assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers, (2) if a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers, and (3) if the Company chooses to stop participating in a multiemployer plan, we could, under certain circumstances, be liable for unfunded vested benefits or other expenses of jointly administered union/management plans. The Company’s participation in multiemployer pension plans is outlined in the table below. The EIN column provides the Employer Identification Number ("EIN") of each plan. Unless otherwise noted, the most recent Pension Protection Act zone status available in December 31, 2021 and 2020 is for the plan’s years ended December 31, 2020, and 2019, respectively. The zone status is based on information that the Company received from the plan, and is certified by the plan’s actuary. Among other factors, plans in the red zone are generally less than 65% funded, plans in the yellow zone are less than 80% funded, and plans in the green zone are at least 80% funded. The FIP column indicates plans for which a financial improvement plan ("FIP") is either pending or has been implemented. The last column lists the expiration dates of the collective bargaining agreements to which the plans are subject. There have been no other significant changes in the number of Company employees covered by the multiemployer plans or other significant events that would affect the comparability of contributions to the plans. The following table lists information about the Company's individually significant multiemployer pension plans: Pension TreeHouse Foods Expiration EIN / Pension Plan Year Ended FIP Contributions Surcharge Of Collective Plan Name Plan Number 2020 2019 (yes or no) 2021 2020 2019 (yes or no) Agreement(s) Bakery and Confectionery Union and Industry 7/22/2023 International Pension Fund 52-6118572 / 001 Red Red Yes $ 2.0 $ 1.6 $ 1.5 Yes 12/4/2023 Central States Southeast and Southwest Areas Pension Fund 36-6044243 / 001 Red Red Yes 1.1 1.1 1.0 Yes 12/31/2022 Retail, Wholesale and Department Store International Union and Industry Pension Fund 63-0708442 / 001 Yellow Yellow Yes — — 0.3 Yes (1) Rockford Area Dairy Industry Local 754, Intl.

(2) A subsidiary of the Company was listed in the plan’s Form 5500 as providing more than 5.0% of the total contributions for the plan's year ended December 31, 2020 and 2019. At the date these financial statements were issued, Forms 5500 were not available for the multiemployer pension plans for the plan year ended December 31, 2021. No other withdrawal liabilities were established related to multiemployer pension plans, as withdrawal from the remaining plans is not probable as of December 31, 2021. The Company contributes to certain multiemployer postretirement benefit plans other than pensions on behalf of employees covered by collective bargaining agreements. These plans are administered jointly by management and union representatives and cover all eligible retirees. These plans are primarily health and welfare funds and carry the same multiemployer risks as identified at the beginning of this Note. Total contributions to these plans were $0.3 million, $0.3 million, and $0.2 million for the years ended December 31, 2021, 2020, and 2019, respectively.

Commitments and Contingencies	19. COMMITMENTS AND CONTINGENCIES Shareholder Class Action and Related Derivative Actions The Company, as nominal defendant, and certain of its directors, officers and former directors and officers are parties to the following four shareholder derivative suits, each of which involves substantially similar claims and allegations: (i) Wells v. Reed, et al. , Case No. 2016-CH-16359 (filed Dec. 22, 2016 in the Circuit Court of Cook County, Illinois), asserting state law claims for breach of fiduciary duty, unjust enrichment and corporate waste; (ii) Lavin v. Reed, et al. , Case No. 17-cv-01014 (filed Feb. 7, 2017 in the United States District Court for the Northern District of Illinois), asserting state law claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and corporate waste; (iii) Bartelt v. Reed, et al. , Case No. 1:19-cv-00835 (filed Feb. 8, 2019 in the United States District Court for the Northern District of Illinois), asserting state law claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and corporate waste, as well as violations of Section 14 of the Securities Exchange Act of 1934; and (iv) City of Ann Arbor Employees' Retirement System v. Reed, et al. , Case No. 2019-CH-06753 (filed June 3, 2019 in the Circuit Court of Cook County, Illinois), asserting claims breach of fiduciary duty, aiding and abetting breaches of fiduciary duty and contribution and indemnification from the individual defendants for losses incurred by the Company. Essentially, all four 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, among other things, that these actions artificially inflated the market price of TreeHouse common stock and resulted in harm to the Company, including the filing of the MPERS federal securities fraud class action (see below). The Bartelt action also includes substantially similar allegations concerning events in 2017. Each of these cases involves allegations similar to those in an earlier-filed, recently resolved federal securities class action, Public Employees' Retirement Systems of Mississippi v. TreeHouse Foods, Inc., et al., Case No. 1:16-cv-10632 (originally captioned Tarara v. TreeHouse Foods, Inc., et al. ) (“ MPERS ”) (filed Nov. 16, 2016), in the United States District Court for the Northern District of Illinois brought on behalf of a class of all purchasers of TreeHouse common stock from January 20, 2016 through and including November 2, 2016. The MPERS complaint asserted claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder and sought, among other things, damages and costs and expenses based on essentially the same facts described above. Following denial of defendants’ motion to dismiss, grant of plaintiff’s motion to certify a class, limited discovery, and extended mediator-facilitated negotiations with Greg Lindstrom of Phillips ADR, on July 14, 2021, the parties filed a stipulation of settlement to resolve the case for 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. After briefing, preliminary approval, notice and a hearing, on November 17, 2021, the Court granted final approval of the settlement and entered final judgment dismissing the case with prejudice on a classwide basis. On November 18, 2021, the Court granted lead counsel’s request for attorneys’ fees and expenses and approved a plan of allocation. Due to the similarity of the derivative complaints, Bartelt was consolidated with Lavin , Ann Arbor was consolidated with Wells , and the parties entered stipulations deferring all of the derivative cases until either summary judgment or settlement of the MPERS class action. Pursuant to a schedule entered in light of the resolution of the MPERS class action, plaintiffs in the consolidated Wells case have until February 28, 2022, to either file a consolidated complaint or designate one of the existing complaints as the operative complaint and a briefing schedule has been set if defendants move to dismiss. The parties are to appear for a status conference or hearing on June 27, 2022. The court in the consolidated Lavin case has asked the parties to submit a case schedule by January 31, 2022. 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 Consolidated Balance Sheets as of December 31, 2021. Employment Related Claims 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 , (the first of which was filed in California state court on October 20, 2015) 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. On January 13, 2022, the Court orally approved the settlement at a final hearing. As a result of these developments, the Company has an accrual for a $9.0 million liability within Accrued expenses in the Consolidated Balance Sheets as of December 31, 2021 with the settlement payment expected to be made in 2022. Other Claims 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. In the Company's opinion, the eventual resolution of such matters, either individually or in the aggregate, is not expected to have a material impact on the Company's financial position, results of operations, or cash flows. However, litigation is inherently unpredictable and resolutions or dispositions of claims or lawsuits by settlement or otherwise could have an adverse impact on our financial position, results of operations or cash flows for the reporting period in which any such resolution or disposition occurs. 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. The matter remains pending, with summary judgment, motions to exclude certain expert opinions, and discovery sanctions motions fully briefed. KGM is denying the allegations made by TreeHouse in the litigation. As such, TreeHouse has not recorded any amount in its Consolidated Financial Statements as of December 31, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	20. DERIVATIVE INSTRUMENTS 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. The Company has entered into long-term interest rate swap agreements to lock into a fixed LIBOR interest rate base that have a notional value of $875.0 million as of both December 31, 2021 and 2020. Under the terms of the agreements, $875.0 million in variable-rate debt is swapped for a weighted average fixed interest rate base of approximately 2.68% in 2020 and 2.91% from 2021 through 2025. 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. As of December 31, 2021 and 2020, the notional value of the foreign currency contracts outstanding was $5.5 million and $7.7 million, respectively. These foreign currency contracts have maturities expiring throughout 2022 as of December 31, 2021. 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 accounts for the contracts as derivatives. 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 December 31, 2021 and 2020, the notional value of the commodity contracts outstanding was $58.8 million and $47.0 million, respectively. These commodity contracts have maturities expiring throughout 2022 as of December 31, 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 Consolidated Balance Sheets, with changes in value being recognized in the Consolidated Statements of Operations. As of December 31, 2021, the notional value of the total return swap contract was $7.0 million. The following table identifies the fair value of each derivative instrument: December 31, 2021 2020 (In millions) Asset derivatives Commodity contracts $ 3.9 $ 12.6 $ 3.9 $ 12.6 Liability derivatives Commodity contracts $ 0.9 $ 0.7 Foreign currency contracts 0.2 — Interest rate swap agreements 51.2 97.4 $ 52.3 $ 98.1 As of December 31, 2021 and 2020, asset derivatives are included within Prepaid expense and other current assets and liability derivatives are included within Accrued expenses in the 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. We recognized the following gains and losses on our derivative contracts in the Consolidated Statements of Operations: Location of Gain (Loss) Year Ended Recognized in Net (Loss) Income 2021 2020 2019 (In millions) Mark-to-market unrealized gain (loss): Commodity contracts Other (income) expense, net $ (8.9) $ 11.7 $ 1.5 Foreign currency contracts Other (income) expense, net (0.2) 0.1 (1.6) Interest rate swap agreements Other (income) expense, net 46.2 (41.7) (46.9) Total unrealized gain (loss) $ 37.1 $ (29.9) $ (47.0) Realized gain (loss): Commodity contracts Manufacturing related to Cost of sales and transportation related to Selling and distribution $ 31.6 $ (9.8) $ 1.5 Foreign currency contracts Cost of sales (0.3) 0.4 0.5 Interest rate swap agreements Interest expense (24.9) (18.4) 6.5 Total return swap contract General and administrative 1.0 — — Total realized gain (loss) $ 7.4 $ (27.8) $ 8.5 Total gain (loss) $ 44.5 $ (57.7) $ (38.5)

Segment Reporting [Abstract]
Segment and Geographic Information and Major Customers	21. SEGMENT AND GEOGRAPHIC INFORMATION AND MAJOR CUSTOMERS 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 two reportable segments, as presented below, are consistent with the manner in which the Company reports its results to the Chief Executive Officer, who has been identified as our 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. Financial information relating to the Company’s reportable segments on a continuing operations basis is as follows: Year Ended December 31, 2021 2020 2019 (In millions) Net sales to external customers: Meal Preparation $ 2,737.7 $ 2,701.4 $ 2,680.7 Snacking & Beverages 1,589.9 1,649.4 1,608.2 Unallocated — (1.1) — Total $ 4,327.6 $ 4,349.7 $ 4,288.9 Direct operating income: Meal Preparation $ 260.8 $ 370.6 $ 381.3 Snacking & Beverages 159.5 234.6 192.8 Total 420.3 605.2 574.1 Unallocated selling, general, and administrative expenses (237.6) (277.2) (270.9) Unallocated cost of sales (1) 11.0 (36.0) (16.5) Unallocated corporate expense and other (1) (172.4) (142.9) (302.8) Operating income (loss) 21.3 149.1 (16.1) Other expense (52.8) (132.0) (139.7) (Loss) income before income taxes $ (31.5) $ 17.1 $ (155.8) Depreciation: Meal Preparation $ 65.9 $ 57.8 $ 60.2 Snacking & Beverages 67.7 64.6 68.6 Corporate office (2) 7.6 10.1 7.7 Total $ 141.2 $ 132.5 $ 136.5 (1) Includes charges related to growth, reinvestment, and restructuring programs and other costs managed at corporate.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation — The Consolidated Financial Statements include the accounts of TreeHouse Foods, Inc. and its 100% owned direct and indirect subsidiaries (the "Company," "TreeHouse,” "we," "us," or "our"). All intercompany balances and transactions are eliminated in consolidation. Discontinued Operations —
Use of Estimates	Use of Estimates — The preparation of our Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") requires management to use judgment to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the Consolidated Financial Statements, and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents — We consider temporary cash investments with an original maturity of three months or less to be cash equivalents. As of December 31, 2021 and 2020, $39.3 million and $92.3 million, respectively, represents cash and cash equivalents held in foreign jurisdictions, in local currencies. The Company is exposed to potential risks associated with its cash and cash equivalents. The Company places its cash and cash equivalents with high credit quality financial institutions. Deposits with these financial institutions may exceed the amount of insurance provided; however, these deposits typically are redeemable upon demand and, therefore, the Company believes the financial risks associated with these financial instruments are minimal.
Accounts Receivable	Accounts Receivable — We provide credit terms to customers in-line with industry standards, perform ongoing credit evaluations of our customers, and maintain allowances for potential credit losses based on historical experience. Customer balances are written off after all collection efforts are exhausted. Estimated product returns, which have not been material, are deducted from sales at the time of shipment.
Inventories	Inventories — Inventories are stated at the lower of cost or net realizable value. We value inventories using the standard cost method which approximates costs determined on the first-in first-out basis. The costs of finished goods inventories include raw materials, labor, and overhead costs.
Leases	Leases — Right-of-use assets and their corresponding lease liabilities are measured and recognized based on the present value of the future minimum lease payments over the lease term at the commencement date. The Company does not record leases with an initial term of 12 months or less on the balance sheet. Expense for these short-term leases is recognized on a straight-line basis over the lease term. The majority of the Company's leases do not provide an implicit rate; therefore, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of future payments for those leases. The Company has elected the practical expedient to apply discount rates to its lease portfolio based on the portfolio approach. The Company grouped the leases into portfolios by remaining lease term. The Company includes lease payments under options to extend or terminate the lease in the measurement of the right-of-use asset and lease liability when it is reasonably certain that it will exercise such options. For operating leases, lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. Finance leases are amortized over the shorter of their lease term or their estimated useful lives, and amortization expense is included in depreciation expense. Fixed lease costs represent the explicitly quantified lease payments prescribed by the lease agreement and are included in the measurement of the right-of-use asset and corresponding lease liability. Variable lease payments that depend on an index or a rate are included in the calculation of the right-of-use asset and lease liability based on the index or rate at lease commencement. Other variable lease payments such as those that depend on the usage or performance of an underlying asset are not included in the measurement of the right-of-use asset or lease liability. The Company has elected the practical expedient to combine lease and nonlease components into a single component for all of its leases.
Property, Plant, and Equipment	Property, Plant, and Equipment — Property, plant, and equipment are stated at acquisition cost, plus capitalized interest on borrowings during the actual construction period of major capital projects. Depreciation and amortization are calculated using the straight-line method over the estimated useful lives of the assets as follows: Asset Useful Life Buildings and improvements 12-40 years Machinery and equipment 3-15 years Office furniture and equipment 3-12 years Building and leasehold improvements are depreciated over the shorter of the estimated useful life of the assets or the remaining useful life of the associated building or lease. We perform impairment tests when circumstances indicate that the carrying value of an asset may not be recoverable. Refer to Note 8 for additional information. Expenditures for repairs and maintenance, which do not improve or extend the life of the assets, are expensed as incurred.
Intangible and Other Assets	Intangible and Other Assets — Identifiable intangible assets with finite lives are amortized over their estimated useful lives as follows: Asset Useful Life Customer-related 5 to 20 years Trademarks 10 to 20 years Non-competition agreements Based on the terms of the agreements Deferred financing costs associated with line-of-credit arrangements Based on the terms of the agreements Formulas/recipes 5 to 7 years Computer software 3 to 10 years All amortization expense related to intangible assets is recorded in Amortization expense in the Consolidated Statements of Operations. Indefinite lived trademarks are evaluated for impairment annually in the fourth quarter or more frequently, if events or changes in circumstances indicate that the asset might be impaired. Impairment is indicated when their book value exceeds fair value. If the fair value of an evaluated asset is less than its book value, the asset is written down to fair value, which is generally based on its discounted future cash flows. Amortizable intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If an evaluation of the undiscounted cash flows indicates impairment, the asset group is impaired to its estimated fair value, which is generally based on discounted future cash flows, and the impairment is allocated to the individual assets within the asset group. Goodwill is evaluated annually in the fourth quarter or more frequently, if events or changes in circumstances require an interim assessment. We assess goodwill for impairment (as of December 31) at the reporting unit level using income and market approaches, employing significant assumptions regarding growth, discount rates, and profitability at each reporting unit. Our estimates under the income approach are determined based on a discounted cash flow model. The market approach uses a market multiple methodology employing earnings before interest, taxes, depreciation, and amortization ("EBITDA") and applies a range of multiples to those amounts in determining the indicated fair value. In determining the multiples used in this approach, we obtain the multiples for selected peer companies using the most recent publicly available information. In determining the indicated fair value of each reporting unit, the Company concludes based on the income approach, and uses the market approach to corroborate, as the Company believes the income approach is the most reliable indicator of the fair value of the reporting units. The resulting value is then compared to the carrying value of each reporting unit to determine if impairment is necessary.
Revenue Recognition	Revenue Recognition — We manufacture and sell food and beverage products to retailers, foodservice distributors, co-manufacturers, and industrial and export channels. Revenue recognition is completed on a point in time basis when product control is transferred to the customer. In general, control transfers to the customer when the product is shipped or delivered to the customer based upon applicable shipping terms. For each contract, the Company considers the transfer of products, each of which is distinct, to be the identified performance obligation generally satisfied within one year. No payment terms beyond one year are granted at contract inception. Most contracts also include some form of variable consideration. The most common forms of variable consideration include discounts, rebates, and sales returns and allowances. Variable consideration is treated as a reduction in revenue when product revenue is recognized. Depending on the specific type of variable consideration, we use either the expected value or most likely amount method to determine the variable consideration. The Company reviews and updates its estimates and related accruals of variable consideration each period based on the terms of the agreements, historical experience, and any recent changes in the market. The Company does not have significant deferred revenue or unbilled receivable balances arising from transactions with customers. We do not capitalize contract inception costs, as contracts are one year or less. The Company does not incur significant fulfillment costs requiring capitalization. Shipping and handling costs associated with outbound freight are included within Selling and distribution expenses and are accounted for as a fulfillment cost as incurred, including shipping and handling costs after control over a product has transferred to a customer. Shipping and handling costs recorded as a component of Selling and distribution expense were approximately $173.5 million, $153.6 million, and $148.3 million for the years ended December 31, 2021, 2020, and 2019, respectively. In addition, any taxes collected on behalf of government authorities are excluded from net sales.
Cost of Sales	Cost of Sales — Cost of sales represents costs directly related to the manufacture and distribution of our products. Such costs include raw materials, packaging, direct and indirect labor, shipping and handling costs, and overhead which includes depreciation of manufacturing and distribution facilities. Shipping and handling costs included in cost of sales reflect inbound freight, inventory warehouse costs, product loading and handling costs, and costs associated with transporting finished products from our manufacturing facilities to distribution warehouses.
Stock-Based Compensation	Stock-Based Compensation — We measure compensation expense for our equity awards at their grant date fair value. The resulting expense is recognized over the relevant service period.
Employee-Related Benefits	Employment-Related Benefits — We provide a range of benefits to our employees, including pension and postretirement benefits to our eligible employees and retirees. We record annual amounts relating to these plans based on calculations specified by GAAP, which include various actuarial assumptions, such as discount rates, assumed investment rates of return, compensation increases, employee turnover rates, and health care cost trend rates. We make modifications to the actuarial assumptions based on plan changes, current rates, and trends when appropriate.
Income Taxes	Income Taxes — The provision for income taxes includes federal, foreign, state, and local income taxes currently payable, and those deferred because of temporary differences between the financial statement and tax bases of assets and liabilities. Deferred tax assets or liabilities are computed based on the difference between the financial statement and income tax bases of assets and liabilities using enacted tax rates. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized. Deferred income tax expenses or credits are based on the changes in the asset or liability from period to period. We account for uncertain tax positions using a "more-likely-than-not" threshold. A tax benefit from an uncertain tax position is recognized if it is more-likely-than-not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position, or the statute of limitations concerning such issues lapses.
Derivatives Instruments	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. All derivatives are recorded on a gross basis and carried at fair value in our Consolidated Balance Sheets. None of the Company's derivative instruments are accounted for under hedge accounting and the changes in their fair value are recorded in the Consolidated Statements of Operations.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions — The functional currency of the Company’s foreign operations is the applicable local currency. The functional currency is translated into U.S. dollars for balance sheet accounts using currency exchange rates in effect as of the balance sheet date, and for revenue and expense accounts using a weighted-average exchange rate during the fiscal year. The translation adjustments are deferred as a separate component of Stockholders’ equity in Accumulated other comprehensive loss. Gains or losses resulting from transactions denominated in foreign currencies and intercompany debt that is not of a long-term investment nature are included in Gain on foreign currency exchange in the Consolidated Statements of Operations. Gains or losses resulting from intercompany debt that is designated a long-term investment are recorded as a separate component of Stockholders' equity in Accumulated other comprehensive loss.
Restructuring Expenses	Restructuring Expenses
Research and Development Costs	Research and Development Costs — We record research and development charges to expense as they are incurred and report them in General and administrative expense in our Consolidated Statements of Operations.
Advertising Costs	Advertising Costs — Advertising costs are expensed as incurred and reported in Selling and distribution expense of our Consolidated Statements of Operations.
Earnings (loss) per share from Continuing Operations	Earnings (Loss) Per Share from Continuing Operations — Basic earnings per share is computed by dividing net income by the number of weighted average common shares outstanding during the reporting period. The weighted average number of common shares used in the diluted earnings per share calculation is determined using the treasury stock method and includes the incremental effect related to the Company’s outstanding stock-based compensation awards.
Recently Issued Accounting Pronouncements	Not yet adopted 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 temporary optional guidance to ease the potential burden in accounting for reference rate reform. ASU 2020-04 was further amended in January 2021 by ASU 2021-01, Reference Rate Reform (Topic 848): Scope. This guidance provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate reform if certain criteria are met. These transactions include contract modifications, hedging relationships, and the sale or transfer of debt securities classified as held-to-maturity. This guidance is effective as of March 12, 2020 through December 31, 2022 and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company has identified agreements that reference LIBOR, including interest rate swap agreements, accounts receivable sale agreements, and debt agreements. The new guidance will be applied as these contracts are modified to reference other rates.
