Summary of Significant Accounting Policies

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.

Change in Segments — In the first quarter of 2020, the Company changed how it manages its business, allocates resources, and goes to market, which resulted in modifications to its organizational and segment structure. All prior period information has been recast to reflect this change in reportable segments. Refer to Note 21 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 Equivalents — We consider temporary cash investments with an original maturity of three months or less to be cash equivalents. As of December 31, 2020 and 2019, $92.3 million and $72.7 million, respectively, represents cash and cash equivalents held in foreign jurisdictions, in local currencies.

Inventories — Inventories are stated at the lower of cost or net realizable value. The Company's inventory is valued using the FIFO method. The costs of finished goods inventories include raw materials, labor, and overhead costs.

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:
AssetUseful Life
Buildings and improvements
12-40 years
Machinery and equipment
3-15 years
Office furniture and equipment
3-12 years

Building improvements are depreciated over the shorter of the estimated useful life of the assets or the remaining useful life.

We perform impairment tests when circumstances indicate that the carrying value of an asset may not be recoverable. Finance leases are amortized over the shorter of their lease term or their estimated useful lives, and amortization expense is included in depreciation expense. 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:
AssetUseful Life
Customer-related
5 to 20 years
Trademarks
10 to 20 years
Non-competition agreementsBased on the terms of the agreements
Deferred financing costs associated with line-of-credit arrangementsBased 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 is written down to its estimated fair value, which is generally based on discounted future cash flows.

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, distributors, food manufacturers, and the food-away-from-home business. 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 $153.6 million, $148.3 million, and $199.2 million for the years ended December 31, 2020, 2019, and 2018, respectively. In addition, any taxes collected on behalf of government authorities are excluded from net sales.
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.

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.

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 review our actuarial assumptions on an annual basis and make modifications to the assumptions based on 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.

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) loss 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 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 charges are incurred as a component of Operating income (loss).

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. Expenditures totaled $16.6 million, $18.8 million, and $19.2 million for the years ended December 31, 2020, 2019, and 2018, respectively.

Advertising Costs —Advertising costs are expensed as incurred and reported in Selling and distribution expense of our Consolidated Statements of Operations.

Accounting Standards Update and Change in Accounting Principle [Abstract]  
Recently Issued Accounting Pronouncements
2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

Adopted

In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, Simplifying the Accounting for Income Taxes (Topic 740), which removes certain exceptions to the general principles in Topic 740 and improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2020 with early adoption permitted. Amendments are to be applied prospectively, except for certain amendments that are to be applied either retrospectively or with a modified retrospective approach through a cumulative effect adjustment recorded to retained earnings. The Company early adopted this guidance during the first quarter of 2020. The adoption did not have a material impact on the Company's financial statements.

In March 2020, the SEC amended Rules 3-10 and 3-16 of Regulation S-X regarding financial disclosure requirements for registered debt offerings involving subsidiaries as either issuers or guarantors and affiliates whose securities are pledged as collateral. This new guidance narrows the circumstances that require separate financial statements of subsidiary issuers and guarantors and streamlines the alternative disclosures required in lieu of those statements. The final rule also allows for the simplified disclosure to be included within Management’s Discussion and Analysis of Financial Condition and Results of Operations. This rule is effective January 4, 2021 with earlier adoption permitted. The Company early adopted this new rule during the first quarter of 2020. In October 2020, the FASB issued ASU 2020-09, Amendments to SEC Paragraphs Pursuant to SEC Release No. 33-10762 (Topic 470), to reflect the SEC’s new disclosure rules on guaranteed debt securities offerings adopted by the Company in the first quarter of 2020.

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. The new 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. Entities may apply the ASU from March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this new ASU on its Consolidated Financial Statements and related disclosures.

Restructuring and Related Activities [Abstract]  
Restructuring Programs
3. RESTRUCTURING PROGRAMS
The Company’s restructuring and margin improvement activities are part of an enterprise-wide transformation to improve long-term profitability of the Company. These activities are aggregated into three categories: (1) TreeHouse 2020 – a long-term growth and margin improvement strategy; (2) Structure to Win – an operating expense improvement program; and (3) other restructuring and plant closing costs (collectively the "Restructuring Programs").

The costs by activity for the Restructuring Programs are outlined below:
 Year Ended December 31,
202020192018
(In millions)
TreeHouse 2020$40.5 $89.5 $118.4 
Structure to Win32.7 15.9 44.1 
Other restructuring and plant closing costs— — 4.2 
Total Restructuring Programs$73.2 $105.4 $166.7 

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 Restructuring Programs to reportable segments when evaluating the performance of its segments. As a result, costs associated with Restructuring Programs are not presented by reportable segment. See Note 21 for additional information.  

Below is a summary of costs by line item for the Restructuring Programs:
Year Ended December 31,

(In millions)
Balance as of December 31, 2019$5.6 
Expenses recognized6.0 
Cash payments(6.7)
Balance as of December 31, 2020$4.9 

Liabilities as of December 31, 2020 associated with total exit cost reserves relate to severance. The severance liability is included in Accrued expenses in the Consolidated Balance Sheets.
(1) TreeHouse 2020 
In the third quarter of 2017, the Company announced TreeHouse 2020, a program that was 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. 
The key information regarding the Company's announced plant closures during the periods presented are as follows:
The Company announced the closure of its Visalia, California Pretzels facility within the Snacking & Beverages segment in 2018, and the closure was completed 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 Dothan, Alabama; Battle Creek, Michigan; and Minneapolis, Minnesota facility closures are classified within Net loss from discontinued operations. Total costs to close these three facilities were $29.7 million. Refer to Note 7 for additional information.
Below is a summary of the overall TreeHouse 2020 program costs by type: 
Year Ended December 31,Cumulative Costs

Total$40.5 $89.5 $118.4 $299.8 $299.8 

For the years ended December 31, 2020, 2019, and 2018, asset-related 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 costs. Asset-related costs are included in Cost of sales while employee-related and other costs are primarily included in Other operating expense, net in the Consolidated Statements of Operations.

(2) Structure to Win
In the first quarter of 2018, the Company announced an operating expenses improvement program ("Structure to Win") designed to align our organizational structure with strategic priorities. The program was intended to drive operational effectiveness, cost reduction, and position the Company for growth with a focus on a lean customer-centric go-to-market team, centralized supply chain, and streamlined administrative functions. This program was completed in 2020. 

Below is a summary of costs by type associated with the Structure to Win program:
Year Ended December 31,Cumulative Costs
To Date		Total Expected Costs
202020192018
(In millions)
Asset-related$— $1.8 $2.1 $4.0 $4.0

Other costs23.3 9.3 20.6 53.2 53.2 
Total$32.7 $15.9 $44.1 $92.7 $92.7 
In the first quarter of 2020, the Company changed how it manages its business, allocates resources, and goes to market, which resulted in modifications to its organizational and segment structure. Transition expenses related to the reorganization, which primarily relate to dedicated employee cost, severance, and consulting are included within Structure to Win. In connection with this reorganization, the Company increased the total expected costs for the Structure to Win program from $60.4 million to $92.7 million during the year ended December 31, 2020.

For the years ended December 31, 2020, 2019, and 2018, asset-related costs primarily consisted of accelerated depreciation, employee-related costs primarily consisted of severance and retention, and other costs primarily consisted of consulting services. Asset-related costs are included in General and administrative expense and the employee-related and other costs are included in Other operating expense, net of the Consolidated Statements of Operations.

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.

Other Restructuring and Plant Closing Costs — The Company continually analyzes its plant network to align operations with the current and future needs of its customers. Facility closure decisions are made when the Company identifies opportunities to lower production costs or eliminate excess manufacturing capacity while maintaining a competitive cost structure, service levels, and product quality. Expenses associated with facility closures are primarily aggregated in Other operating expense, net of the Consolidated Statements of Operations, with the exception of asset-related costs, which are recorded in Cost of sales.

Below is a summary of costs by type associated with the other restructuring and plant closing costs:
Year Ended December 31,
 2018
 (In millions)
Asset-related$1.3 
Other closure costs0.3 
Total$1.6 

For the year ended December 31, 2018, asset-related costs primarily consisted of inventory dispositions and other closure costs primarily consisted of third-party costs. Asset-related costs are included in Cost of sales and other closure costs are recorded in Other operating expense, net in the Consolidated Statements of Operations. There were no costs associated with other restructuring and plant closing costs for the years ended December 31, 2020 and 2019.
Charges related to other cost reduction activities that are not related to our plant closings above totaled $2.6 million for the year ended December 31, 2018. These charges were primarily the result of a Private Brands plant closure initiated prior to TreeHouse’s acquisition and severance-related costs.

Leases [Abstract]  
Leases
4. LEASES

The Company has changed its method of accounting for leases effective January 1, 2019 due to the adoption of ASU 2016-02, Leases (Topic 842), using the modified retrospective transition method. Under this transition method, financial results reported in periods prior to 2019 are unchanged.

The Company has operating and finance leases for manufacturing facilities, warehouses and distribution centers, office space, and certain equipment. Remaining lease terms for these leases range from 1 year to 13 years. Some of the Company’s leases include options to extend the leases for up to 28 years, and some include options to terminate the leases within 1 year.

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.

Supplemental balance sheet information related to leases was as follows:

Total lease liabilities$182.4 $194.4 

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.

Discount Rates

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 weighted-average discount rates for the Company's operating and finance leases are as follows:

December 31,
Weighted-average discount rate20202019
Operating leases4.5 %4.7 %
Finance leases3.1 %3.5 %

Lease Payments
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. 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.

Receivables Sales Program
5. RECEIVABLES SALES PROGRAM

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

The following table includes the outstanding amount of accounts receivable sold under the Receivables Sales Program and the amount collected but not yet remitted to the financial institutions:

(In millions)
Outstanding accounts receivable sold$284.3 $243.0 
Collections not remitted to financial institutions202.8 158.3 

Receivables sold under the Receivables Sales Program are de-recognized 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 amount collected but not yet remitted to the financial institutions is included in Accounts payable in the Consolidated Balance Sheets.

The loss on sale of receivables was $2.4 million, $4.3 million, and $3.8 million for the years ended December 31, 2020, 2019, and 2018, respectively, and is included in Other expense, net in the Consolidated Statements of Operations. The Company has not recognized any servicing assets or liabilities as of December 31, 2020 or December 31, 2019, as the fair value of the servicing arrangement as well as the fees earned were not material to the financial statements.

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 purchase price of approximately $239.2 million in cash, subject to customary purchase price adjustments. Ebro Foods is a Spanish-based multinational food group operating primarily in the pasta and rice sectors. The acquisition includes the following regional brands: Skinner, No Yolks, American Beauty, Creamette, San Giorgio, Prince, Light ‘n Fluffy, Mrs. Weiss’, Wacky Mac, P&R Procino-Rossi, and New Mill. Additionally, the Company and Riviana Foods have a mutual put or call right to acquire or sell, respectively, the equipment utilized in the Riviana Foods Fresno, California facility for $5.0 million by December 31, 2021. 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. These costs are included in General and administrative expense of the Consolidated Statements of Operations.

The following table summarizes the preliminary purchase price allocation of the fair value of net tangible and intangible assets acquired and liabilities assumed:

(In millions)
Inventories$20.0 
Property, plant, and equipment, net48.2 
Customer relationships68.0 
Trade names43.0 
Formulas/recipes2.3 
Goodwill57.8 
Operating lease right-of-use assets0.1 
Assets acquired239.4 
Assumed liabilities(0.2)
Total purchase price$239.2 

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 expected useful lives. The Company increased the cost of acquired inventories by approximately $3.1 million and expensed $2.1 million as a component of Cost of sales during the year ended December 31, 2020. The Company has allocated $57.8 million of goodwill to the Meal Preparation segment. Goodwill arises principally as a result of expansion opportunities of its scale to better serve its regional and national customers and plant operation synergies across its legacy Pasta category. The goodwill resulting from this acquisition is tax deductible. The purchase price allocation in the table above is preliminary and subject to the finalization of the Company’s valuation analysis, including a working capital adjustment, and the option to exercise its right to acquire the $5.0 million equipment utilized in the Fresno, California facility.

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.

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

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 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 million in cash, subject to customary purchase price adjustments. The Company classified the proceeds within Net cash (used in) provided by 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 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 is 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.

Ready-to-eat Cereal

On May 1, 2019, the Company entered into a definitive agreement to sell its Ready-to-eat ("RTE") Cereal business to Post Holdings, Inc. ("Post"), which until that time had been a component of the Meal Preparation reporting segment. The sale of this business is part of the Company's portfolio optimization strategy. On December 19, 2019, the Federal Trade Commission objected to the sale to Post. On January 13, 2020, the sale to Post was terminated and the Company announced its intention to pursue a sale of the RTE Cereal business to an alternative buyer. The Company continues to market the business and is committed to a plan of sale to dispose of the business.

The RTE Cereal business continues to be classified as a discontinued operation as of December 31, 2020. Expected disposal losses of $51.2 million and $74.5 million were recognized as asset impairment charges during the years ended December 31, 2020 and 2019, respectively, within Net loss from discontinued operations. The expected disposal loss for the RTE Cereal business is remeasured each period at the lower of carrying value or estimated fair value less costs to sell and is included in the
valuation allowance in the balance sheet. Completion of the sale may be for amounts that could be significantly different from the current fair value estimate. The Company's estimate of fair value will be evaluated and recognized each reporting period until the divestiture is complete.

The Company has reflected the Snacks division (through the date of sale) and RTE Cereal business 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.

In-Store Bakery Facilities

During the fourth quarter of 2019, the Company reached the decision to sell two of its In-Store Bakery facilities located in Fridley, Minnesota and Lodi, California, which manufacture breads, rolls, and cakes for in-store retail bakeries and food-away-from-home customers. These two facilities were included within the Snacking & Beverages reporting segment. The associated assets met the held for sale accounting criteria as of December 31, 2019 and were classified accordingly in the Consolidated Balance Sheets. These two facilities did not meet the criteria to be presented as a discontinued operation. The disposal group was measured at fair value, and the Company recognized the expected disposal loss as an impairment charge of $41.1 million during the year ended December 31, 2019, as the fair value was determined to be less than the carrying value of the associated assets, including the related goodwill. The impairment is recognized within Asset impairment in the Consolidated Statements of Operations.

On January 10, 2020, the Company entered into a definitive agreement to sell these facilities. On April 17, 2020, the sale of these facilities was completed for $24.0 million, subject to customary purchase price adjustments. 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.

The following table represents detail of assets held for sale as of December 31, 2019:

The Company also had $2.7 million of assets classified as held for sale as of December 31, 2019 related to the closure of the Minneapolis, Minnesota facility. The sale of these assets was completed during the first quarter of 2020.

McCann's Business

On July 16, 2018, the Company completed the divestiture of its McCann's business. The McCann's business produced steel cut Irish oatmeal and was previously reported within the Meal Preparation segment. This divestiture did not meet the criteria to be presented as a discontinued operation. The Company recognized a gain upon divestiture of $14.3 million within Other operating expense, net in the Consolidated Statements of Operations during the year ended December 31, 2018.

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 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.

Depreciation expense was $132.5 million, $136.5 million, and $145.0 million in 2020, 2019, and 2018, respectively.

Goodwill

As a result of the changes in organizational structure completed in the first quarter of 2020, the Company now has the following two reportable segments: Meal Preparation and Snacking & Beverages. See Note 21 for additional information regarding the change in segment structure.

In connection with the change in organizational structure completed in the first quarter of 2020, the Company allocated goodwill and accumulated impairment loss balances as of January 1, 2020 between reporting units using a relative fair value allocation approach. The change was considered a triggering event indicating a test for goodwill impairment was required as of January 1, 2020. The Company performed the impairment test, which did not result in impairment losses.

The Company performed the annual impairment assessment on indefinite-lived intangibles as of December 31, 2020 and 2019, resulting in no impairment losses. The fair value of one of our trademarks with a book value of $16.4 million as of December 31, 2020 exceeds its book value by 12%. Based on our plans for this product line, we do not anticipate impairment of this trademark in the foreseeable future. However, if our revenue and profit expectations are not met or certain factors outside of our control, such as discount rates, change then this trademark could become impaired. Changes in our estimates or any of our other assumptions used in our analysis could result in a different conclusion.

Asset Impairment

During 2019, the Company recognized $45.2 million of finite lived intangible asset impairment. Refer to Note 8 for additional information.

There were no other impairments related to finite lived intangibles.

Considerable management judgment is necessary to evaluate the impact of operating changes and to estimate future cash flows. Assumptions used in our impairment evaluations, such as forecasted growth rates and our cost of capital, are consistent with our internal projections and operating plans.

Estimated amortization expense on intangible assets for the next five years is as follows:

The Company assessed the realizability of its deferred tax assets and has recorded valuation allowances for certain foreign non-capital loss carryforwards, state net operating loss carryforwards, and state tax credit carryforwards that will more likely than not expire unused. 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 year ended December 31, 2014 and forward; for Canadian purposes, the Company is open to examination for the tax year ended December 31, 2011 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, 2015 and forward.
The Internal Revenue Service ("IRS") is currently examining the TreeHouse Foods, Inc. & Subsidiaries’ 2019 tax year. Our Canadian operations are under exam by the Canadian Revenue Agency ("CRA") for tax years 2012 through 2015 and 2017 through 2018. These examinations are expected to be completed in 2021. The Company has examinations in process with various state taxing authorities, which are expected to be completed in 2021.
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:

Unrecognized tax benefits are included in Other long-term liabilities of the Consolidated Balance Sheets. Of the amount accrued at December 31, 2020 and 2019, $5.5 million and $3.4 million, respectively, would impact net income from continuing operations when settled. Of the amounts accrued at December 31, 2020 and 2019, $4.8 million and $9.9 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 $5.1 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 $2.0 million of the $5.1 million would affect net income when settled.
The Company recognizes interest expense (income) and penalties related to unrecognized tax benefits in income tax expense. During the years ended December 31, 2020, 2019, and 2018, the Company recognized $(1.4) million, $(0.2) million, and $(0.2) million of interest and penalties in income tax expense from continuing operations, respectively. The Company has accrued approximately $2.4 million and $3.9 million for the payment of interest and penalties at December 31, 2020 and 2019, respectively, of which $1.7 million and $3.7 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 $29.3 million income tax benefit related to the NOL carryback provisions of the CARES Act for the year ended December 31, 2020.

During the first quarter of 2008, the Company entered into an intercompany financing structure that results in the recognition of
certain foreign earnings subject to a low effective tax rate. For the years ended December 31, 2020, 2019, and 2018, the Company recognized a tax benefit of approximately $1.4 million. $2.1 million, and $2.3 million, respectively, related to this item. During the fourth quarter of 2020 the Company exited the intercompany financing structure.

Credit Agreement

On December 1, 2017, the Company entered into the Second Amended and Restated Credit Agreement (the "Credit Agreement") which amends, restates, and replaces the Company’s prior credit agreement, dated as of February 1, 2016 (as amended from time to time prior to February 1, 2016, the "Prior Credit Agreement"). 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.

On June 11, 2018, the Company entered into Amendment No. 1 (the "Amendment") to the Credit Agreement. Under the Amendment, 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 the Amendment. In connection with this Amendment, $0.6 million in lender fees are amortized ratably through January 31, 2025 and $1.8 million of fees are amortized ratably through February 1, 2023.

On August 26, 2019, the Company entered into Amendment No. 2 (the "Amendment") to the Credit Agreement. This Amendment permanently maintains the secured status of the credit facility and the maximum permitted leverage ratio at 4.5x.  Absent the Amendment, 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 the Amendment.

The Company’s average interest rate on debt outstanding under its Credit Agreement for the year ended December 31, 2020 was 2.27%. Including the impact of the interest rate swap agreements in effect as of December 31, 2020, the average rate increased to 3.86%.

Revolving Credit Facility — As of December 31, 2020, $727.1 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, 2020, there were $22.9 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. 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. The maturity date is January 31, 2025. 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 $900 million term loan which amended and extended the Company’s existing tranche A-1 and tranche A-2 term loans. The maturity date is February 1, 2023. 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.

2022 Notes — The Company previously issued 2022 Notes. On August 26, 2020, the Company, through the trustee, issued a notice of redemption to redeem all of the $375.9 million outstanding principal of its 2022 Notes at a price of 100% of the principal amount, plus accrued and unpaid interest to, but not including, the redemption date (the "2022 Notes Redemption"). The 2022 Notes Redemption was completed on September 25, 2020. For 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.

2024 Notes — On January 29, 2016, the Company completed an exempt offering under Rule 144A and Regulation S of the Securities Act of the 2024 Notes. The net proceeds from the issuance of the 2024 Notes (approximately $760.7 million after deducting issuance costs, providing an effective interest rate of 6.23%) were used to fund a portion of the purchase price of the Private Brands Business. Interest is payable on February 15 and August 15 of each year. The payments began on August 15, 2016. The 2024 Notes will mature on February 15, 2024.

During the year ended December 31, 2018, the Company repurchased $24.1 million and $172.1 million of its 2022 Notes and 2024 Notes, respectively. The Company wrote off $2.4 million of debt issuance costs and recorded a loss of $4.2 million related to the repurchases totaling $6.6 million within Loss on extinguishment of debt of the Consolidated Statement of Operations.

The Company may redeem some or all of the 2024 Notes upon not less than 30 nor more than 60 days' notice, at the applicable redemption prices described in the Indenture plus accrued and unpaid interest, if any, up to but not including the redemption date. In the event of certain change of control events, as described in the Indenture, the Company may be required to purchase the 2024 Notes from the holders at a purchase price of 101% of the principal amount plus any accrued and unpaid interest. 

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, beginning 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 2024 Notes and 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 2024 Notes and 2028 Notes will be senior unsecured obligations of the Company. The Company’s payment obligations under the 2024 Notes and 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 2024 Notes and 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 2024 Notes or 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 2024 Notes or 2028 Notes for so long as the 2024 Notes or 2028 Notes are rated investment grade by the two rating agencies.

Interest Rate Swap Agreements — As of December 31, 2020, 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, 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. At December 31, 2019, the aggregate fair value of the Company's total debt was $2,146.1 million and its carrying value was $2,118.8 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 values of the Company's 2022 Notes, 2024 Notes, and 2028 Notes were 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 $4.1 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, 2020 and December 31, 2019, deferred financing costs of $18.3 million and $15.7 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.

Common Stock — The Company has authorized 90 million shares of common stock with a par value of $0.01 per share. No dividends have been declared or paid.

Share Repurchase Authorization — On November 2, 2017, the Company announced that the Board of Directors adopted a stock repurchase program. The stock repurchase program authorizes the Company to repurchase up to $400 million of the Company’s common stock at any time, or from time to time. Any repurchases under the program may be made by means of open market transactions, negotiated block transactions, or otherwise, including pursuant to a repurchase plan administered in accordance with Rules 10b5-1 and 10b-18 under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The size and timing of any repurchases will depend on price, market and business conditions, and other factors. The Company has the ability to make discretionary repurchases up to an annual cap of $150 million under the $400 million total authorization. Any shares repurchased will be held as treasury stock.

The following table summarizes the Company's repurchases of its common stock:

Earnings Per Share
14. EARNINGS PER SHARE

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.

The following table summarizes the effect of the share-based compensation awards on the weighted average number of shares outstanding used in calculating diluted earnings (loss) per share:

For the years ended December 31, 2019 and 2018, weighted average common shares outstanding is the same for the computations of both basic and diluted shares outstanding because the Company had a net loss for the period. Equity awards, excluded from our computation of diluted earnings per share because they were anti-dilutive, were 1.4 million, 1.6 million, and 1.7 million for the years ended December 31, 2020, 2019, and 2018, respectively.

In 2018, the Company entered into an amended employment agreement with our former Chief Executive Officer. The amended plan resulted in the modification of his outstanding equity awards by accelerating the vesting dates, changing outstanding performance units to vest at target, and extending the exercisability of options outstanding. Modification of the existing awards resulted in a charge of $10.0 million in the year ended December 31, 2018. The impact of this modification on expense recognized for stock options, restricted stock units, and performance units was $1.2 million, $3.8 million, and $5.0 million, respectively.
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.

Restricted Stock Units — Employee restricted stock unit awards generally vest based on the passage of time. These awards generally vest in approximately three equal installments on each of the first three anniversaries of the grant date. Director restricted stock units vest on the first anniversary of the grant date. Certain directors have deferred receipt of their awards until either their departure from the Board of Directors or a specified date.

Performance Units — Performance unit awards are granted to certain members of management. These awards contain service and performance conditions. For each of the three performance periods, 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. For performance unit awards granted in 2020, performance goals are set and measured annually with earned amounts accrued for settlement at the end of the three year cycle. Additionally, for the cumulative performance period, a number of units will accrue, 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, less any units previously accrued. 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.

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, 2020, 2019, and 2018, the Company made matching and profit sharing contributions to the plans of $20.4 million, $19.4 million, and $19.3 million, respectively.
Pension and Postretirement Benefits — Certain of our 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 2021 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 2021 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. In 2018, we adopted 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, 2020, our master trust was invested as follows: investments in equity securities were at 42%; investments in fixed income were at 52%; investments in hedge funds were at 5%; and cash and cash equivalents were less than 1%. We believe the allocation of our master trust investments as of December 31, 2020 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, 2020 and 2019 was as follows:

Multiemployer Pension Plans - The Company contributes to several multiemployer pension plans on behalf of employees covered by collective bargaining agreements. 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, 2020 and 2019 is for the plan’s years ended December 31, 2019, and 2018, 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.

19. COMMITMENTS AND CONTINGENCIES
Litigation, Investigations, and Audits - On November 16, 2016, a purported TreeHouse shareholder filed a class action captioned Tarara v. TreeHouse Foods, Inc., et al., Case No. 1:16-cv-10632, in the United States District Court for the Northern District of Illinois against TreeHouse and certain of its officers. The complaint, amended on March 24, 2017, is purportedly brought on behalf of all purchasers of TreeHouse common stock from January 20, 2016 through and including November 2, 2016. It asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder and seeks, among other things, damages and costs and expenses. On December 22, 2016, another purported TreeHouse shareholder filed an action captioned Wells v. Reed, et al., Case No. 2016-CH-16359, in the Circuit Court of Cook County, Illinois, against TreeHouse and certain of its officers. This complaint, purportedly brought derivatively on behalf of TreeHouse, asserts state law claims against certain officers for breach of fiduciary duty, unjust enrichment, and corporate waste. On February 7, 2017, another purported TreeHouse shareholder filed an action captioned Lavin v. Reed, et al., Case No. 17-cv-01014, in the Northern District of Illinois, against TreeHouse and certain of its officers. This complaint is also purportedly brought derivatively on behalf of TreeHouse, and it asserts state law claims against certain officers for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and corporate waste. On February 8, 2019, another purported TreeHouse shareholder filed an action captioned Bartelt v. Reed, et al., Case No. 1:19-cv-00835, in the United States District Court for the Northern District of Illinois. This complaint is purportedly brought derivatively on behalf of TreeHouse and asserts state law claims against certain officers for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and corporate waste, in addition to asserting violations of Section 14 of the Securities Exchange Act of 1934. Finally, on June 3, 2019, another purported TreeHouse shareholder filed an action captioned City of Ann Arbor Employees’ Retirement System v. Reed, et al., Case No. 2019-CH-06753, in the Circuit Court of Cook County, Illinois, against TreeHouse and certain of its officers. Like Wells, Lavin, and Bartelt, this complaint is purportedly brought derivatively on behalf of TreeHouse and asserts claims for contribution and indemnification, breach of fiduciary duty, and aiding and abetting breaches of fiduciary duty.

All five complaints make substantially similar allegations (though the amended complaint in Tarara now contains additional detail). Essentially, the complaints allege that TreeHouse, under the authority and control of the individual defendants: (i) made certain false and misleading statements regarding the Company’s business, operations, and future prospects; and (ii) failed to disclose that (a) the Company’s private label business was underperforming; (b) the Company’s Flagstone business was underperforming; (c) the Company’s acquisition strategy was underperforming; (d) the Company had overstated its full-year
2016 guidance; and (e) TreeHouse’s statements lacked reasonable basis. The complaints allege that these actions artificially inflated the market price of TreeHouse common stock during the class period, thus purportedly harming investors. The Bartelt action also includes substantially similar allegations concerning events in 2017, and the Ann Arbor complaint also seeks contribution from the individual defendants for losses incurred by the company in these litigations. We believe that these claims are without merit and intend to defend against them vigorously.

Since its initial docketing, the Tarara matter has been re-captioned as Public Employees’ Retirement Systems of Mississippi v. TreeHouse Foods, Inc., et al., in accordance with the Court’s order appointing Public Employees’ Retirement Systems of Mississippi as the lead plaintiff. On May 26, 2017, the Public Employees’ defendants filed a motion to dismiss, which the court denied on February 12, 2018. On April 12, 2018, the Public Employees’ defendants filed their answer to the amended complaint. On April 23, 2018, the parties filed a joint status report with the Court, which set forth a proposed discovery and briefing schedule for the Court’s consideration. On July 13, 2018, lead plaintiff filed a motion to certify the class, and defendants filed their response in opposition to the motion to certify the class on October 8, 2018. On November 12, 2018, the parties filed an agreed motion to stay proceedings to allow them to explore mediation. The motion was granted on November 19. The parties thereafter engaged in mediation but failed to resolve the dispute. On March 29, 2019, the parties resumed litigation by filing an agreed motion for extension of time, which was granted on April 9. Under that schedule, lead plaintiff filed its reply class certification brief on May 17, 2019.

On February 26, 2020, the court granted lead plaintiff’s motion for class certification. Defendants then filed a petition for permissive appeal of the class certification order in the United States Court of Appeals for the Seventh Circuit on March 11, 2020. After ordering lead plaintiff to file a response, the court denied the petition on May 4, 2020.

On December 16, 2019, the parties agreed to extend the case schedule 90 days. This agreed motion was granted on December 25, 2019. At a status conference on March 10, 2020, the parties informed the court that they intended to engage in a second mediation and the court extended then-upcoming deadlines under the case schedule, pending a further status report from the parties regarding the extent of the stay needed to facilitate mediation. The court subsequently issued multiple general orders as a result of the COVID-19 outbreak, which together postponed all case deadlines for a total of 77 days. On June 9, 2020, the parties filed a joint status report informing the court that mediation had been scheduled for July 9, 2020. The next day, the court stayed the case pending the outcome of mediation. Any in-person mediation was thereafter postponed due to ongoing COVID-19 concerns.

Due to the similarity of the complaints, the parties in Wells and Lavin entered stipulations deferring the litigation until the earlier of (i) the court in Public Employees’ entering an order resolving defendants’ anticipated motion to dismiss therein or (ii) plaintiffs’ counsel receiving notification of a settlement of Public Employees’ or until otherwise agreed to by the parties. On September 27, 2018, the parties in Wells and Lavin filed joint motions for entry of agreed orders further deferring the matters in light of the Public Employees’ Court’s denial of the motion to dismiss in February 2018. The Wells and Lavin Courts entered the agreed orders further deferring the matters on September 27, 2018 and October 10, 2018, respectively. On June 25, 2019, the parties jointly moved to consolidate the Bartelt matter with Lavin, so that it would be subject to the Lavin deferral order. This motion was granted on June 27, 2019, and Bartelt is now consolidated with Lavin and deferred. There is no set status date in Lavin at this time. Similarly, Ann Arbor was consolidated with Wells on August 13, 2019, and is now deferred. In Wells, the plaintiffs have notified the court that they intend to move to modify the deferral order to lift the stay. Plaintiff’s motion is due February 8, 2021, and briefing is to be completed by March 20, 2021. A status hearing is scheduled for March 22, 2021.

The Company is party to matters challenging its wage and hour practices. These matters include a number of class actions consolidated under the caption Negrete v. Ralcorp Holdings, Inc., et al, pending in the U.S. District Court for the Central District of California, in which plaintiffs allege a pattern of violations of California and/or federal law at three former Company manufacturing facilities in California. The Company has notified the Court that it has reached a preliminary settlement understanding with the Negrete plaintiffs that would resolve all associated matters for a payment by the Company of $9.0 million. The preliminary understanding reached with the Negrete plaintiffs involves procedural requirements and Court approval which may continue through 2021. As a result of these developments, the Company has an accrual for a $9.0 million liability as of December 31, 2020.

In addition, the Company is party in the ordinary course of business to certain claims, litigation, audits, and investigations. The Company will record an accrual for a loss contingency when it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. The Company believes it has established adequate accruals for liabilities that are probable and reasonably estimable that may be incurred in connection with any such currently pending or threatened matter, none of which are significant. In the Company’s opinion, the settlement of any such currently pending or threatened matter is not expected to have a material impact on the Company’s financial position, results of operations, or cash flows.

Derivative Instruments
20. 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, and commodity price risk. Derivative contracts are entered into for periods consistent with the related underlying exposure and do not constitute positions independent of those exposures. The Company does not enter into derivative instruments for trading or speculative purposes.
Interest Rate Risk — The Company manages its exposure to changes in interest rates by optimizing the use of variable-rate and fixed-rate debt and by utilizing interest rate swaps to hedge our exposure to changes in interest rates, to reduce the volatility of our financing costs, and to achieve a desired proportion of fixed versus floating-rate debt, based on current and projected market conditions.
As of December 31, 2020, the Company had entered into $875.0 million of long-term interest rate swap agreements to lock into a fixed LIBOR interest rate base. Under the terms of the agreements, $875.0 million in variable-rate debt was swapped for a weighted average fixed interest rate base of approximately 2.68% in 2020 and 2.91% from 2021 through 2025. These instruments are not accounted for under hedge accounting and the changes in their fair value are recorded in the Consolidated Statements of Operations.

Foreign Currency Risk — Due to the Company’s foreign operations, it is exposed to foreign currency risk. The Company enters into foreign currency contracts to manage the risk associated with foreign currency cash flows. This includes, but is not limited to, using foreign currency contracts to establish a fixed foreign currency exchange rate for the net cash flow requirements for purchases of inventory, sales of finished goods, and future settlement of foreign-denominated assets and liabilities. These contracts do not qualify for hedge accounting and changes in their fair value are recognized in the Consolidated Statements of Operations. As of December 31, 2020, the Company had $7.7 million of foreign currency contracts outstanding, expiring throughout 2021 and 2022.

Commodity Risk — Certain commodities the Company uses in the production and distribution of its products are exposed to market price risk. The Company utilizes derivative contracts to manage this risk. The majority of commodity forward contracts are not derivatives, and those that are generally qualify for the normal purchases and normal sales scope exception under the guidance for derivative instruments and hedging activities and, therefore, are not subject to its provisions. For derivative commodity contracts that do not qualify for the normal purchases and normal sales scope exception, the Company records their fair value on the Consolidated Balance Sheets, with changes in value being recorded in the Consolidated Statements of Operations.

The Company’s derivative commodity contracts may include contracts for diesel, oil, plastics, natural gas, electricity, resin, corn, coffee, 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 corn, coffee, 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, 2020, the Company had outstanding contracts for the purchase of 0.1 million megawatts of electricity, expiring throughout 2021 and 2022; 20.1 million gallons of diesel, expiring throughout 2021; 4.5 million dekatherms of natural gas, expiring throughout 2021; 3.6 million pounds of coffee, expiring throughout 2021; and 21.0 million pounds of resin, expiring throughout 2021.

As of December 31, 2020 and 2019, asset derivatives are included within Other assets, net and liability derivatives are included within Accrued expenses in the Consolidated Balance Sheets.
The fair values of the commodity contracts, foreign currency contracts, and interest rate swap agreements 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, and interest rate swap agreements are based on an analysis comparing the contract rates to the market rates at the balance sheet date.

Segment and Geographic Information and Major Customers
21. SEGMENT AND GEOGRAPHIC INFORMATION AND MAJOR CUSTOMERS
On January 1, 2020, the Company changed how it manages its business, allocates resources, and goes to market, which resulted in modifications to its organizational and segment structure. As a result, the Company reorganized from a three segment structure previously organized by product category (Baked Goods, Beverages, and Meal Solutions) to a two segment structure organized by market dynamics (Meal Preparation and Snacking & Beverages). In connection with this segment reorganization, the Company also recast expenses related to its commercial sales organization from direct selling, general, and administrative expense previously included within the segments to corporate unallocated selling, general, and administrative expense to align with the revised organizational structure. All prior period information has been recast to reflect this change in reportable segments.

The Company manages operations on a company-wide basis, thereby making determinations as to the allocation of resources in total rather than on a segment-level basis. The Company has designated reportable segments based on how management views its business. The Company does not segregate assets between segments for internal reporting. Therefore, asset-related information has not been presented. The reportable segments, as presented below, are consistent with the manner in which the Company reports its results to the Chief Operating Decision Maker.

The principal products that comprise each segment are as follows:

Meal Preparation – Our Meal Preparation segment sells aseptic cheese & pudding; baking and mix powders; hot cereals; jams, preserves, and jellies; liquid and powdered non-dairy creamer; macaroni and cheese; mayonnaise; Mexican, barbeque, and other sauces; pasta; pickles and related products; powdered soups and gravies; refrigerated and shelf stable dressings and sauces; refrigerated dough; single serve hot beverages; skillet dinners; and table and flavored syrups.

Snacking & Beverages – Our Snacking & Beverages segment sells bars; broths; candy; cookies; crackers; in-store bakery products; pita chips; powdered drinks; pretzels; ready-to-drink coffee; retail griddle waffles, pancakes, and French toast; specialty teas; and sweeteners.

The Company evaluates the performance of its segments based on net sales dollars and direct operating income. Direct operating income is defined as gross profit less freight out, sales commissions, and direct selling, general, and administrative expenses. The amounts in the following tables are obtained from reports used by senior management and do not include income taxes. Other expenses not allocated include unallocated selling, general, and administrative expenses, unallocated costs of sales, and unallocated corporate expenses (amortization expense, other operating expense, and asset impairment). The accounting policies of the Company’s segments are the same as those described in the summary of significant accounting policies set forth in Note 1.
Financial information relating to the Company’s reportable segments on a continuing operations basis, revised to reflect the new segment structure, is as follows:

Summary of Significant Accounting Policies (Policies)
 12 Months Ended
Dec. 31, 2020
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 — 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.
Change in Segments — In the first quarter of 2020, the Company changed how it manages its business, allocates resources, and goes to market, which resulted in modifications to its organizational and segment structure. All prior period information has been recast to reflect this change in reportable segments. Refer to Note 21 for additional information.
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 Equivalents Cash Equivalents — We consider temporary cash investments with an original maturity of three months or less to be cash equivalents. As of December 31, 2020 and 2019, $92.3 million and $72.7 million, respectively, represents cash and cash equivalents held in foreign jurisdictions, in local currencies.
Inventories Inventories — Inventories are stated at the lower of cost or net realizable value. The Company's inventory is valued using the FIFO method. The costs of finished goods inventories include raw materials, labor, and overhead costs.
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:
AssetUseful Life
Buildings and improvements
12-40 years
Machinery and equipment
3-15 years
Office furniture and equipment
3-12 years

Building improvements are depreciated over the shorter of the estimated useful life of the assets or the remaining useful life.

We perform impairment tests when circumstances indicate that the carrying value of an asset may not be recoverable. Finance leases are amortized over the shorter of their lease term or their estimated useful lives, and amortization expense is included in depreciation expense. 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:
AssetUseful Life
Customer-related
5 to 20 years
Trademarks
10 to 20 years
Non-competition agreementsBased on the terms of the agreements
Deferred financing costs associated with line-of-credit arrangementsBased 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 is written down to its estimated fair value, which is generally based on discounted future cash flows.

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, distributors, food manufacturers, and the food-away-from-home business. 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 $153.6 million, $148.3 million, and $199.2 million for the years ended December 31, 2020, 2019, and 2018, respectively. In addition, any taxes collected on behalf of government authorities are excluded from net sales.
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.
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.
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 review our actuarial assumptions on an annual basis and make modifications to the assumptions based on 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 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.
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) loss 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 — Restructuring charges principally consist of 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 charges are incurred as a component of Operating income (loss).
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.
Recently Issued Accounting Pronouncements
Adopted

In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, Simplifying the Accounting for Income Taxes (Topic 740), which removes certain exceptions to the general principles in Topic 740 and improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2020 with early adoption permitted. Amendments are to be applied prospectively, except for certain amendments that are to be applied either retrospectively or with a modified retrospective approach through a cumulative effect adjustment recorded to retained earnings. The Company early adopted this guidance during the first quarter of 2020. The adoption did not have a material impact on the Company's financial statements.

In March 2020, the SEC amended Rules 3-10 and 3-16 of Regulation S-X regarding financial disclosure requirements for registered debt offerings involving subsidiaries as either issuers or guarantors and affiliates whose securities are pledged as collateral. This new guidance narrows the circumstances that require separate financial statements of subsidiary issuers and guarantors and streamlines the alternative disclosures required in lieu of those statements. The final rule also allows for the simplified disclosure to be included within Management’s Discussion and Analysis of Financial Condition and Results of Operations. This rule is effective January 4, 2021 with earlier adoption permitted. The Company early adopted this new rule during the first quarter of 2020. In October 2020, the FASB issued ASU 2020-09, Amendments to SEC Paragraphs Pursuant to SEC Release No. 33-10762 (Topic 470), to reflect the SEC’s new disclosure rules on guaranteed debt securities offerings adopted by the Company in the first quarter of 2020.

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. The new 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. Entities may apply the ASU from March 12, 2020 through December 31, 2022. The Company is currently evaluating the impact of this new ASU on its Consolidated Financial Statements and related disclosures.
