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. Certain prior year amounts in the Consolidated Statements of Cash Flows have been reclassified to conform to the current period presentation.

In the first quarter of 2017, the Company completed changes in its organizational structure that resulted in a change in how the Company manages its business and allocates resources. As a result, the Company revised its reportable segments to reflect how management currently reviews financial information and allocates resources. See Note 22 for additional details. All prior period amounts have been recast to reflect the change in reportable segments.

On February 1, 2016, the Company acquired all of the outstanding common stock of Ralcorp Holdings, Inc., the Missouri corporation through which the private brands business of ConAgra Foods, Inc. (“Private Brands Business”) was operated. Ralcorp Holdings, Inc. was renamed TreeHouse Private Brands, Inc. during the first quarter of 2016. The results of operations of the Private Brands Business are included in our financial statements from the date of acquisition and are included in the Baked Goods, Condiments, Meals, and Snacks segments, as applicable.

The Private Brands Business was on a 4-4-5 fiscal calendar during the first three quarters of 2016, which resulted in differences between the fiscal quarter ends of the Private Brands Business and the Company. In the fourth quarter of 2016, the Company changed the fiscal year end of the Private Brands Business to December 31. This change in reporting period for the Private Brands Business represents a change in accounting principle that is preferable as it provides more timely and relevant financial information to the users of its financial statements and eliminates the previously existing difference in reporting periods. The Company determined that it was impracticable to retrospectively apply this change to the first three quarters of 2016 as the data to determine the cumulative effect of the change was not available and cannot be prepared. Therefore, the Company reported the change in accounting principle prospectively in net income for the three months ended December 31, 2016 and did not retrospectively apply the effects of this change in prior periods, the cumulative effect of which the Company believes would be immaterial in all periods.

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, 2017 and 2016, $49.4 million and $61.9 million, respectively, represents cash and equivalents held in foreign jurisdictions, in local currencies, that are convertible into other currencies. The cash and equivalents held in foreign jurisdictions are expected to be used for general corporate purposes in foreign jurisdictions, including capital projects and acquisitions. The Prepaid expenses and other current assets line on the Consolidated Balance Sheets also includes restricted cash of $2.7 million as of December 31, 2017, which relates to cash held to meet certain insurance requirements.

Inventories — Inventories are stated at the lower of cost or market. Pickle inventories are valued using the LIFO method and a portion of our snack nuts inventories are valued using the weighted average costing approach, while all of our other inventories are 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:

Asset		Useful Life
Buildings and improvements		12-40 years
Machinery and equipment		3-15 years
Office furniture and equipment		3-12 years

We perform impairment tests when circumstances indicate that the carrying value of an asset may not be recoverable. Capitalized 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:

Asset		Useful Life
Customer relationships		5 to 20 years
Trademarks		10 to 20 years
Non-competition agreements		Based on the terms of the agreements
Deferred financing costs associated with line-of-credit arrangements		Based on the terms of the agreements
Formulas/recipes		5 to 7 years
Computer software		2 to 7 years

All amortization expense related to intangible assets is recorded in the Amortization expense line of 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 publically 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.

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. See Note 15.

Revenue Recognition — Sales are recognized when persuasive evidence of an arrangement exists, the price is fixed or determinable, title and risk of loss transfer to the customer, and there is a reasonable assurance of collection of the sales proceeds. Product is shipped FOB shipping point or FOB destination, depending on our agreement with the customer. Sales are reduced by certain sales incentives, some of which are recorded by estimating expense based on our historical experience.

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.

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 are included in Other income, net in the Consolidated Statements of Operations.

Shipping and Handling Fees — Our shipping and handling costs are included in both cost of sales and selling and distribution expense, depending on the nature of such costs. Shipping and handling costs included in cost of sales reflect inventory warehouse costs, product loading and handling costs, and costs associated with transporting finished products from our manufacturing facilities to distribution warehouses. Shipping and handling costs included in selling and distribution expense consist primarily of the cost of shipping products to customers through third party carriers. Shipping and handling costs recorded as a component of selling and distribution expense were approximately $220.8 million, $198.8 million, and $87.2 million for the years ended December 31, 2017, 2016, and 2015, respectively.

Derivative Financial Instruments — From time to time, we utilize derivative financial instruments including interest rate and commodity swaps, foreign currency contracts, and forward purchase contracts to manage our exposure to interest rate, foreign currency, and commodity price risks. We do not hold or issue financial instruments for speculative or trading purposes. The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value. Derivatives that are not designated as hedges according to GAAP must be adjusted to fair value through earnings. For derivative instruments that are designated as cash flow hedges, the effective portion of the gain or loss is reported as Accumulated other comprehensive loss and reclassified into earnings in the same period when the hedged transaction affects earnings. The ineffective gain or loss is recognized in current earnings. Commodity forward contracts 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 further information about our derivative instruments, see Note 20.

Capital Lease Obligations — Capital lease obligations represent machinery and equipment financing obligations, which are generally payable in monthly installments of principal and interest, and are collateralized by the related assets financed.

Insurance Accruals — We retain selected levels of property and casualty risks, primarily related to employee health care, workers’ compensation claims, and other casualty losses. Many of these potential losses are covered under conventional insurance programs with third party carriers having high deductible limits. In other areas, we are self-insured with stop-loss coverage. Accrued liabilities for incurred but not reported losses related to these retained risks are calculated based upon loss development factors that consider a number of elements, including claims history and expected trends. We develop these accruals with external insurance brokers and actuaries.

Facility Closing and Reorganization Costs — We periodically record facility closing and reorganization charges when we have identified a facility for closure or other reorganization opportunity, developed a plan, and notified the affected employees. These charges are incurred as a component of operating (loss) income. See Note 3 for more information.

Research and Development Costs — We record research and development charges to expense as they are incurred and report them in the General and administrative expense line of our Consolidated Statements of Operations. Expenditures totaled $30.8 million, $29.6 million, and $14.3 million for the years ended December 31, 2017, 2016, and 2015, respectively.

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

Accounting Changes And Error Corrections [Abstract]

Recently Issued Accounting Pronouncements

2.	RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

Adopted

In the fourth quarter of 2016, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No 2016-09, Improvements to Employee Share-Based Payment Accounting. Under this ASU, excess tax benefits and deficiencies are no longer recognized as additional paid-in capital in the Condensed Consolidated Balance Sheets. The ASU requires recognition of excess tax benefits and deficiencies in the Condensed Consolidated Statements of Operations, which resulted in the recognition of an income tax benefit of $4.3 million in 2016. As the Company adopted the ASU in the fourth quarter of 2016, any related adjustments were required to be reflected as of the beginning of the fiscal year of adoption. See Note 23 for the impact of these income tax benefits on the first three quarters of 2016. Additionally, the ASU requires excess tax benefits to be reported as a component of operating activities in the Consolidated Statements of Cash Flows. Excess tax benefits of $4.3 million and $5.3 million were retrospectively reclassified from financing to operating activities in the Consolidated Statements of Cash Flows for the years ended December 31, 2016 and 2015, respectively. The Company did not elect to change its accounting policy to account for forfeitures as they occur and, as a result, the Company will continue to estimate forfeitures. The effects of the adoption of the other provisions of this ASU were immaterial.

In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, to simplify the accounting for adjustments made to provisional amounts. This ASU requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The ASU also requires acquirers to present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. This ASU is effective on a prospective basis for fiscal periods beginning after December 15, 2015. The Company adopted the ASU for the fiscal 2016 reporting period.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory, which requires entities to measure inventory at the lower of cost and net realizable value (“NRV”). This ASU will not apply to inventory valued under the last-in-first-out method. Under current guidance, an entity is required to measure inventory at the lower of cost or market, with market defined as replacement cost, NRV, or NRV less a normal profit margin. The three market measurements added complexity and reduced comparability in the valuation of inventory. FASB issued this ASU as part of its simplification initiative to address these issues. The ASU is effective on a prospective basis for fiscal years, and interim periods within those years, beginning after December 15, 2016. The Company prospectively adopted the ASU during the first quarter of 2017, the impact of which was not significant.

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment, to eliminate the second step of the goodwill impairment test. This ASU requires an entity to measure a goodwill impairment loss as the amount by which the carrying value of a reporting unit exceeds its fair value. Additionally, an entity should include the income tax effects from any tax deductible goodwill on the carrying value of the reporting unit when measuring a goodwill impairment loss, if applicable. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company early adopted the ASU during the third quarter of 2017. The assessment and related impairment charge recorded in 2017 was computed under this guidance. See Note 9 to our Consolidated Financial Statements for more information.

Not yet adopted

In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities, which simplifies hedge accounting by better aligning an entity’s financial reporting for hedging relationships with its risk management activities. The ASU also simplifies the application of the hedge accounting guidance. The new guidance is effective on January 1, 2019, with early adoption permitted. For cash flow hedges existing at the adoption date, the standard requires adoption on a modified retrospective basis with a cumulative-effect adjustment to the Consolidated Balance Sheet as of the beginning of the year of adoption. The amendments to presentation guidance and disclosure requirements are required to be adopted prospectively. The Company is currently assessing the impact and timing of adoption of this ASU.

In March 2017, the FASB issued ASU No. 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which revises how employers that sponsor defined benefit pension and other postretirement plans present net periodic benefit cost. The ASU requires an employer to present the service cost component in the same income statement line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside of any subtotal of operating income. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The standard requires adoption on a retrospective basis for the presentation of net benefit cost components. The Company does not expect this standard will have a significant impact upon adoption.

In November 2016, the FASB issued ASU No. 2016-18, Restricted Cash, to require that restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period amounts on the statement of cash flows. The Company currently classifies changes in restricted cash as an investing activity in the Consolidated Statements of Cash Flows. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company does not expect this standard will have a significant impact upon adoption.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, to provide cash flow statement classification guidance for certain cash receipts and payments including (a) debt prepayment or extinguishment costs; (b) contingent consideration payments made after a business combination; (c) insurance settlement proceeds; (d) distributions from equity method investees; (e) beneficial interests in securitization transactions and (f) application of the predominance principle for cash receipts and payments with aspects of more than one class of cash flows. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period, in which case adjustments should be reflected as of the beginning of the fiscal year that includes the interim period. The amendments in this ASU should be applied retrospectively. The Company does not expect this standard will have a significant impact upon adoption.

In February 2016, the FASB issued ASU No. 2016-02, Leases, to increase transparency and comparability by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The main difference between existing GAAP and this ASU is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under existing GAAP. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The standard requires that entities apply the effects of these changes using a modified retrospective approach, which includes a number of optional practical expedients. The adoption of this ASU will result in a significant increase to the Company’s Balance Sheets for lease liabilities and lease assets, and the Company is currently assessing the impact that this standard will have upon adoption on its accounting policies, processes, system requirements, internal controls, and disclosures. The Company has established a project plan, is in the process of completing an initial review of its lease contracts, and is considering impacted policies and processes.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which introduced a new framework to be used when recognizing revenue in an attempt to reduce complexity and increase comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The standard requires that entities apply the effects of these changes to all prior years presented, upon adoption, using either the full retrospective method, which presents the impact of the change separately in each prior year presented, or the modified retrospective method, which includes the cumulative changes to all prior years presented in beginning retained earnings in the year of initial adoption. The Company expects to use the modified retrospective method. The FASB also issued ASU No. 2016-10, Identifying Performance Obligations and Licensing, and ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients, in April 2016 and May 2016, respectively, which amend the guidance in ASU 2014-09 and have the same effective date as the original standard. The Company has finalized the impact that these standards will have on its accounting policies, processes, system requirements, internal controls, and disclosures. The Company has established a project plan, completed an initial review of its customer contracts, and is updating policies and procedures. Based upon implementation procedures, the Company determined there will be no significant changes in its revenue recognition policies. Upon adoption, the Company will reclassify approximately $56.9 million from accounts receivable to contract liabilities on the balance sheet.

Restructuring and Margin Improvement Activities

Restructuring And Related Activities [Abstract]

Restructuring and Margin Improvement Activities

3.	RESTRUCTURING AND MARGIN IMPROVEMENT ACTIVITIES

The Company’s restructuring and margin improvement activities are part of an enterprise-wide transformation to improve long-term profitability of the Company. Upon completion of our multi-year multi-phase programs, the projects are expected to deliver higher margin sales growth and reduced expenses resulting in margin expansion.

Expenses associated with these programs are primarily aggregated in the Other operating expense, net line of the Condensed Consolidated Statements of Operations, with the exception of asset-related costs, which are recorded in Cost of sales. The Company does not allocate restructuring and margin improvement activities costs to reportable segments when evaluating the performance of its segments. As a result, restructuring and margin improvement activity costs by reportable segment have not been presented. See Note 22 for more information.

Below is a summary of costs by line item:

	Year Ended December 31, 2017		Year Ended December 31, 2016

Cost of sales	$	46.3	$	7.9
Other operating expenses, net		41.4		13.1
Total	$	87.7	$	21.0

TreeHouse 2020

In the third quarter of 2017, the Company announced TreeHouse 2020, a program intended to expand margins through optimization of our manufacturing network, transformation of our mixing centers and warehouse footprint, and leveraging of systems and processes to drive performance. TreeHouse 2020 is expected to produce significant savings to achieve our operating margin expansion targets creating reinvestment opportunities to drive future growth.

This program will be executed in multiple phases over the next several years. The key elements of Phase 1 include the closure of the Company’s Brooklyn Park, Minnesota and Plymouth, Indiana facilities, as well as the downsizing of the Dothan, Alabama facility. By the end of the fourth quarter of 2017, we successfully transitioned production at the Brooklyn Park and Plymouth facilities. The facility downsizing at Dothan, Alabama is expected to be complete in the third quarter of 2018. In the fourth quarter of 2017, the company expanded its workstreams related to cost reduction and margin improvement activities and selling, general, and administrative reductions. These workstreams and the dedicated employees assigned to them are delivering value by increasing our capacity utilization, expanding operating margins, and streamlining our plant structure to optimize our supply chain.

The key information regarding the Company’s announced facility closures related to TreeHouse 2020 is outlined in the table below:

(1)	The downsizing of this facility began in January 2017 and is expected to last approximately 15 months. On January 31, 2018, the Company announced the full closure of this facility. The costs associated with the full closure are included in the TreeHouse 2020 section.

Total expected costs to close the City of Industry, California, Ayer, Massachusetts, Ripon, Wisconsin, and Delta, British Columbia facilities have been reduced by approximately $5.0 million, $0.9 million, $1.4 million, and $1.5 million, respectively, since the initial announcements, while total expected costs to close the Azusa, California and Battle Creek, Michigan facilities have been increased by approximately $6.2 million and $0.9 million, respectively, since their initial announcement.

Below is a summary of the plant closing costs by type of cost:

	Year Ended December 31, 2017		Cumulative Costs To Date		Total Expected Costs
	(In millions)
Asset-related	$	6.9	$	17.1	$	17.1

Other closure costs		14.1		18.6		20.0
Total	$	24.1	$	46.1	$	48.3

For the years ended December 31, 2017, asset-related costs primarily consisted of accelerated depreciation; employee-related costs primarily consisted of severance; and other costs primarily consisted of third-party costs.

Other individually insignificant cost reduction activities not related to our plant closings above totaled $5.9 million for the year ended December 31, 2017 and were primarily the result of a Private Brands plant closure initiated prior to TreeHouse’s acquisition. Other cost reduction activities were $3.2 million for the year ended December 31, 2016.

Liabilities recorded as of December 31, 2017 associated with these plant closings relate to severance and the partial withdrawal from a multiemployer pension plan. The severance liability is included in the Accounts payable and accrued expenses line of the Consolidated Balance Sheets while the multiemployer pension plan withdrawal liability is included in the Other long-term liabilities line of the Consolidated Balance Sheets.

Acquisitions

4.	ACQUISITIONS

Private Brands Business

On February 1, 2016, the Company acquired the Private Brands Business, which is primarily engaged in manufacturing, distributing, and marketing private label products to retail grocery, food away from home, and industrial and export customers. The business’s primary product categories include snacks, retail bakery, pasta, cereal, bars, and condiments. The purchase price, after considering working capital adjustments, was $2,644.4 million, net of acquired cash. The acquisition was funded by $835.1 million in net proceeds from a public sale of the Company’s common stock, $760.7 million in net proceeds from a private issuance of senior unsecured notes (“2024 Notes”), and a $1,025.0 million term loan (“Term Loan A-2”) which was refinanced in 2017, with the remaining balance funded by borrowings from the Company’s revolving credit facility (the “Revolving Credit Facility”). The acquisition resulted in a broader portfolio of products and further diversified the Company’s product categories.

The Private Brands Business 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 Baked Goods, Condiments, Meals, and Snacks segments. Included in the Company’s Consolidated Statements of Operations are the Private Brands Business’s net sales of approximately $2,992.9 million and income before income taxes of $117.3 million from the date of acquisition through December 31, 2016. Integration costs of $9.7 million, which were included in the Cost of sales and General and administrative expense lines of the Consolidated Statements of Operations for the year ended December 31, 2016, were included in determining income before income taxes.

The purchase price was allocated to net tangible and intangible assets acquired and liabilities assumed as follows:

	(In millions)
Cash	$	43.3
Receivables		162.7
Inventory		443.7
Property, plant, and equipment		809.6

Deferred taxes		(152.8	)
Assumed current liabilities		(246.6	)
Assumed long-term liabilities		(150.3	)
Total purchase price	$	2,687.7

The Company allocated $496.1 million to customer relationships with retail grocery customers, which have an estimated life of 13 years, and $14.8 million to customer relationships with food away from home customers, which have an estimated life of 10 years. The Company allocated $33.0 million to trade names, which have an estimated life of 10 years. The Company allocated $23.2 million to formulas, which have an estimated life of 5 years. The Company allocated $19.6 million to capitalized software with estimated lives of 1 to 5 years, depending on expected use. The aforementioned intangibles will be amortized over their expected useful lives. Indemnification assets related to taxes of approximately $13.8 million were also recorded. The Company increased the cost of acquired inventories by approximately $8.4 million and expensed the amount as a component of Cost of sales. The Company has allocated $555.6 million, $1.1 million, $73.3 million, $413.3 million, and $97.9 million of goodwill to the Baked Goods, Beverages, Condiments, Meals, and Snacks segments, respectively. Goodwill arises principally as a result of expansion opportunities and synergies across both new and legacy product categories. None of the goodwill resulting from this acquisition is tax deductible. The Company incurred approximately $35.2 million in acquisition costs in 2016 and none in 2017. These costs are included in the General and administrative expense line of the Consolidated Statements of Operations.

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 was determined using the cost approach. Real property fair values were determined using the cost and market approaches, while the fair value of personal property was determined using the indirect 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 acquisition of the Private Brands Business had been completed as of January 1, 2015. 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 issuance of common stock, interest expense related to the financing of the business combination, and related income taxes. Excluded from the 2016 pro forma results are $35.2 million of costs incurred by the Company in connection with the acquisition. The 2015 pro forma results include $1.3 billion in asset impairment charges incurred by the seller. 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.

We determine the appropriate classification of our investments at the time of purchase and reevaluate such designation as of each balance sheet date. The Company accounts for investments in debt and marketable equity securities as held-to-maturity, available-for-sale, or trading, depending on their classification. The investments held by the Company are classified as trading securities and are stated at fair value, with changes in fair value recorded as a component of the Interest income or Interest expense line on the Consolidated Statements of Operations. Cash flows from purchases, sales, and maturities of trading securities are included in cash flows from investing activities in the Consolidated Statements of Cash Flows based on the nature and purpose for which the securities were acquired.

Our investments include U.S. equity, non-U.S. equity, and fixed income securities that are classified as short-term investments on the Consolidated Balance Sheets. The U.S. equity, non-U.S. equity, and fixed income securities are classified as short-term investments as they have characteristics of other current assets and are actively managed.

For the year ended December 31, 2017, we recognized unrealized losses totaling $0.1 million that are included in the Interest expense line of the Consolidated Statements of Operations and $2.0 million in unrealized gains that are included in the Interest income line of the Consolidated Statements of Operations. Additionally, for the year ended December 31, 2017, we recognized a realized gain on investments totaling $0.2 million that was included in the Interest income line of the Consolidated Statements of Operations. When securities are sold, their cost is determined based on the FIFO method.

Receivables [Abstract]
Receivables Sales Agreement	6. RECEIVABLES SALES AGREEMENT In December 2017, the Company entered into an agreement (the “Receivables Sales Agreement”), to sell, on a revolving basis, certain trade accounts receivable balances to an unrelated third-party financial institution. Transfers under this agreement are accounted for as sales of receivables resulting in the receivables being de-recognized from the Consolidated Balance Sheet. The Receivables Sales Agreement provides for the continuing sale of certain receivables on a revolving basis until terminated by either party. The maximum receivables that may be sold at any time is $200.0 million. For the year ended December 31, 2017, $74.6 million of accounts receivable have been sold via this arrangement. The proceeds from these sales of receivables are included in Cash flows from operating activities in the Consolidated Statements of Cash Flows. The recorded net loss on sale of receivables is $0.2 million for the year ended December 31, 2017 and is included in the Other income, net line in the Consolidated Statements of Operations. The Company has no retained interest in the receivables sold under the program above, however the Company does have collection and administrative responsibilities for the sold receivables. The Company has not recorded any servicing assets or liabilities as of December 31, 2017 as the fair value of the servicing arrangement as well as the fees earned were not material to the financial statements.

Goodwill and Intangible Assets

9.	GOODWILL AND INTANGIBLE ASSETS

Goodwill

As a result of the changes in organizational structure completed in the first quarter of 2017, the Company has the following five operating segments, which are also its reporting units: Baked Goods, Beverages, Condiments, Meals, and Snacks. See Note 22 for more information.

The Company allocated the goodwill balance as of January 1, 2017 between the new 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, 2017. The Company performed the first step of the impairment test, which did not result in the identification of any impairment losses. Changes in the carrying amount of goodwill for the years ended December 31, 2017 and 2016 are as follows:

	Baked
	Goods		Beverages		Condiments			Meals		Snacks			Total
	(In millions)

Upon completion of the annual goodwill impairment analysis as of December 31, 2017, the Company recorded impairment losses of $276.4 million related to the Snacks reporting unit. This reporting unit did not achieve the forecasted results for the year ended December 31, 2017. The Company finalized its budgeting process in the fourth quarter which resulted in reduced future revenue and profitability expectations. The primary factor impacting the future revenue and profitability expectations for the Snacks reporting unit was competitive pressures. These changes in expectations and the related reductions in discounted future cash flows resulted in book values that exceeded the fair values for these reporting units, which required the recognition of impairment losses. The income approach was used to calculate the impairment. This approach utilizes projected cash flow estimates developed by the Company to determine fair value, which are unobservable, Level 3 inputs. Unobservable inputs are used to measure fair value to the extent that relevant observable inputs are not available. The Company developed our estimates using the best information available at the time.

Upon completion of the annual goodwill impairment analysis as of December 31, 2016, the Company recorded impairment losses of $333.4 million and $11.5 million related to the Snacks and Condiments reporting units, respectively. These reporting units did not achieve their forecasted results for the year ended December 31, 2016 and after finalizing the budgeting process in the fourth quarter of 2016, resulted in reduced future revenue and profitability expectations due to competitive pressures.

The goodwill impairment losses are included in the Impairment of goodwill and other intangible assets line of the Consolidated Statements of Operations. No other instances of goodwill impairment were identified in connection with annual impairment tests.

Approximately $430.0 million of goodwill is deductible for tax purposes.

Indefinite-lived Intangible Assets

The carrying amounts of our intangible assets with indefinite lives, other than goodwill, as of December 31, 2017 and 2016 are as follows:

	December 31,
	2017		2016
	(In millions)
Trademarks	$	22.8	$	21.6
Total indefinite lived intangibles	$	22.8	$	21.6

The Company performed the annual impairment assessment on indefinite-lived intangibles as of December 31, 2017 resulting in no impairment losses.

Upon completion of the annual indefinite lived intangibles analysis as of December 31, 2016, the Company recorded a $3.6 million impairment loss related to the Saucemarker® trademark, which was included in the Impairment of goodwill and other intangible assets line of the Consolidated Statements of Operations. The impairment loss was determined using the relief from royalty method, and resulted from the reduced revenue and profitability expectations related to the Condiments reporting unit, as described above. The Company also changed the classification of this trademark from indefinite lived to finite lived. No other impairments were identified related to indefinite lived intangibles.

Finite-lived Intangible Assets

The gross carrying amounts and accumulated amortization of intangible assets, with finite lives, as of December 31, 2017 and 2016 are as follows:

	December 31,

In the fourth quarter, the Company determined the carrying value of certain long-lived assets may not be recoverable due to the decline in forecasted future cash flows in the Snacks segment. As a result, we evaluated long-lived assets for impairment and determined that the book value of the customer-related assets in the Snacks segment were not recoverable. The customer-related assets were determined to have no fair value using an excess earnings approach and an impairment charge of $273.3 million was recorded on all remaining Snacks segment customer-related assets. The excess earnings approach calculates the Company’s earnings above an expected return on the Company’s tangible assets. This approach utilizes projected cash flow estimates developed by the Company to determine fair value, which are unobservable, Level 3 inputs. Unobservable inputs are used to measure fair value to the extent that relevant observable inputs are not available. The Company developed our earnings estimates using the best information available at the time. No other impairments were identified related to the remaining long-lived assets of asset groups. The impairment is included in the Impairment of goodwill and other intangible assets line of the Consolidated Statements of Operations.

In 2016, the Company recorded a $3.8 million impairment loss related to the Amport® trademark, which is included in the Impairment of goodwill and other intangible assets line of the Consolidated Statements of Operations. The Amport® trademark was related to the Snacks segment. The impairment loss was determined using the relief from royalty method and resulted from the transition of certain products previously sold under this trademark to the Goodfields® trademark in the fourth quarter of 2016. No other impairments were identified related to finite lived intangibles.

As of December 31, 2017, the weighted average remaining useful lives for the amortizable intangible assets are (1) customer-related at 11.1 years, (2) contractual agreements at 0.5 years, (3) trademarks at 8.2 years, (4) formulas/recipes at 3.0 years, and (5) computer software at 4.5 years. The weighted average remaining useful life in total for all amortizable intangible assets is 10.3 years as of December 31, 2017.

Total intangible assets, excluding goodwill, as of December 31, 2017 and 2016 were $773.0 million and $1,137.6 million, respectively. Amortization expense on intangible assets was $114.1 million, $109.9 million, and $60.6 million for the years ended December 31, 2017, 2016, and 2015, respectively. Estimated amortization expense on intangible assets for the next five years is as follows:

	(In millions)
2018	$	101.0
2019		98.4
2020		96.3
2021		87.5
2022		83.5

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.

On December 22, 2017, the Tax Act was signed into law making significant changes to the Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21%, limitation of the tax deduction for interest expense to 30% of adjusted earnings, the transition of U.S international taxation from a worldwide tax system to a territorial system, allowing for the full expensing of certain qualified property and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings. The changes are effective for tax years beginning after December 31, 2017.

Shortly after enactment of the Tax Act, the SEC issued Staff Accounting Bulletin No. 118 ("SAB 118") to address the application of US GAAP in situations where a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. To the extent that a company’s accounting for the Tax Act is incomplete but it is able to provide a reasonable estimate, it must record a provisional amount in the financial statements. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740.

In relation to our initial analysis of the impact of the Tax Act, we have recorded a net tax benefit of $104.2 million primarily consisting of (1) a $108.4 million benefit related to adjustments to our net deferred tax liability and (2) a $9.6 million expense related to the one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings. The adjustments to our net deferred tax liability and the liability related to the transition tax are provisional amounts based on information available as of December 31, 2017. These amounts are subject to change due to, among other things, additional analysis, changes in interpretations and assumptions the Company has made, and additional regulatory guidance that may be issued. Any subsequent adjustment to these amounts will be recorded to tax expense in the quarter when the analysis is complete.

The Tax Act also creates a new requirement that certain income (i.e., Global Intangible Low Taxed Income or “GILTI”) earned by controlled foreign corporations (“CFCs”) must be included currently in the gross income of the CFC’s U.S. shareholder. Because of the complexity of the GILTI tax rules, we are continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, we are allowed to make an accounting policy election of either (1) treating taxes due of future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred or (2) factoring such amounts into the company’s measurement of deferred taxes. We have not made any adjustments related to potential GILTI tax in our financial statements and have not made a policy decision regarding whether to record deferred taxes on GILTI.

The Company has income tax net operating loss carryforwards related to its domestic and international operations which have a 20 year definite life. The Company has recorded a deferred tax asset of $10.5 million reflecting the benefit of $42.2 million in loss carryforwards. All of the loss carryforwards expire between 2033 and 2037. The Company has recorded a deferred tax asset of $28.4 million reflecting the benefit of foreign tax credit carryforwards. The foreign tax credits have a 10 year life and expire in 2026 and 2027. The Company also has state net operating loss and income tax credit carryforwards. The Company has recorded a deferred tax asset of $8.3 million reflecting the benefit of state net operating losses of $168.2 million. The state net operating loss carryforwards have a 1 to 20 year life and expire between 2018 and 2037. The Company has recorded a deferred tax asset of $13.2 million reflecting the benefit of state tax credit carryforwards. The state income tax credits have a 1 to 15 year life and expire between 2018 and 2031.

The Company has recorded a valuation allowance of $14.9 million and $8.9 million for the years ended December 31, 2017 and 2016, respectively. The Company assessed the realizability of its deferred tax assets and has determined that certain foreign non-capital loss carryforwards, state net operating loss carryforwards, and state tax credit carryforwards will more likely than not expire unused.

The Company or one of its subsidiaries files income tax returns in the U.S., Canada, Italy, 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, 2008 and forward; for Italian purposes, the Company is open to examination for the tax years ended September 30, 2012 and forward; and for the various U.S. states the Company is generally open to examination for the tax year ended December 31, 2012 and forward.

The Internal Revenue Service (“IRS”) is currently examining the TreeHouse Foods, Inc. & Subsidiaries’ 2015 tax year. Our Canadian operations are under exam by the Canadian Revenue Agency (“CRA”) for tax years 2008 through 2015. These examinations are expected to be completed in 2018. The Italian Agency of Revenue (“IAR”) is examining the 2007 through 2009 and 2013 tax years of our Italian operations. The IAR examinations are not expected to be completed prior to 2020 due to a backlog of appeals before the agency. The Company has examinations in process with various state taxing authorities, which are expected to be completed in 2018.

During the year, the Company recorded adjustments to its unrecognized tax benefits. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

	Year Ended December 31,
	2017			2016			2015
	(in millions)
Unrecognized tax benefits beginning balance	$	31.4		$	19.5			13.2
Additions and reductions based on tax positions related to the current year		1.1			—			0.1
Additions and reductions based on tax positions of prior years		0.4			1.8			1.5
Additions resulting from acquisitions		—			14.4			6.4
Reductions due to statute lapses		(4.6	)		(4.2	)		(1.4	)
Reductions related to settlements with taxing authorities		(2.0	)		—			—
Foreign currency translation		0.1			(0.1	)		(0.3	)
Unrecognized tax benefits ending balance	$	26.4		$	31.4		$	19.5

Unrecognized tax benefits are included in the Other long-term liabilities line of the Consolidated Balance Sheets. Included in the balance at December 31, 2017 are amounts that are offset by deferred taxes (i.e., temporary differences). Of the amount accrued at December 31, 2017 and 2016, $5.7 million and $7.3 million, respectively, would impact net income when settled. Of the amounts accrued at December 31, 2017 and 2016, $20.7 million and $20.1 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 $9.5 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 $1.4 million of the $9.5 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, 2017, 2016, and 2015, the Company recognized $1.2 million, $0.8 million, and $0.1 million of interest and penalties in income tax expense, respectively. The Company has accrued approximately $5.5 million and $4.6 million for the payment of interest and penalties at December 31, 2017 and 2016, respectively, of which $5.3 million and $4.3 million is indemnified.

As of December 31, 2017, the Company has approximately $82.3 million of undistributed earnings generated by its foreign subsidiaries which was subject to the one-time transition tax on cumulative foreign earnings required by the Tax Act. As there will not be an incremental tax cost on the future repatriation of these earnings, the Company no longer considers the earnings to be permanently reinvested outside the U.S.

During the first quarter of 2008, the Company entered into an intercompany financing structure that results in the recognition of foreign earnings subject to a low effective tax rate. For the years ended December 31, 2017 and 2016, the Company recognized a tax benefit of approximately $3.9 and $3.8 million, respectively, related to this item.

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.

In connection with the Credit Agreement, $5.2 million in fees will be amortized ratably through January 31, 2025 and $13.6 million of fees will be amortized ratably through February 1, 2023. Fees associated with Term Loan A and Term Loan A-1 (the “Term Loans”) are presented as a direct deduction from outstanding debt, while fees associated with the Revolving Credit Facility are presented as an asset.

The Company’s average interest rate on debt outstanding under the Prior Credit Agreement and under the Credit Agreement for the year ended December 31, 2017 was 2.976%.

Revolving Credit Facility — As of December 31, 2017, $716.0 million of the aggregate commitment of $750 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, 2017, there were $34.0 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 1.60%, or (ii) a Base Rate (as defined in the Credit Agreement), plus a margin ranging from 0.20% to 0.60%. 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 0.30%.

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.; Cains Foods, Inc.; Cains Foods L.P.; Cains GP, LLC; Flagstone Foods, Inc., Protenergy Holdings, Inc.; Protenergy Natural Foods, Inc.; TreeHouse Private Brands, Inc. (formerly Ralcorp Holdings, Inc.); American Italian Pasta Company.; Nutcracker Brands, Inc.; 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 4.0 to 1.0 (or no greater than 4.5 to 1.0 for a measurement period that includes a fiscal quarter in which the Company entered into a permitted acquisition), 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 2.075%, or (ii) a Base Rate (as defined in the Credit Agreement), plus a margin ranging from 0.675% to 1.075 %. 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. As of December 31, 2017, $498.8 million was outstanding under Term Loan A.

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. As of December 31, 2017, $897.8 million was outstanding under Term Loan A-1.

Term Loan A-2 — On December 1, 2017, Term Loan A-2 was paid off as part the Credit Agreement utilizing borrowings under Term Loan A and Term Loan A-1.

2022 Notes — On March 11, 2014, the Company completed its underwritten public offering of $400 million in aggregate principal amount of 4.875% notes due March 15, 2022 (the “2022 Notes”). The net proceeds of $394.0 million ($400.0 million less underwriting discount of $6.0 million, providing an effective interest rate of 4.99%) were used to extinguish the Company’s previously issued 7.75% notes due on March 1, 2018 (the “2018 Notes”). Interest is payable on March 15 and September 15 of each year. The 2022 Notes will mature on March 15, 2022.

The Company may redeem all or some of the 2022 Notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices as set forth in the indenture plus any accrued or unpaid interest to the applicable redemption date. Subject to certain limitations, in the event of a change in control of the Company, the Company will be required to make an offer to purchase the 2022 Notes at a purchase price equal to 101% of the principal amount of the 2022 Notes, plus accrued and unpaid interest up to the purchase date.

2024 Notes — On January 29, 2016, the Company completed an exempt offering under Rule 144A and Regulation S of the Securities Act of $775 million in aggregate principal amount of 6.0% notes due February 15, 2024. 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.

The Company may redeem some or all of the 2024 Notes at any time on or after February 15, 2019 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 addition, prior to February 15, 2019, the Company may redeem all or a portion of the 2024 Notes at a price equal to 100% of the principal amount plus the “make-whole” premium set forth in the Indenture plus accrued and unpaid interest, if any, up to but not including the redemption date. The Company may also redeem up to 40% of the 2024 Notes prior to February 15, 2019 with the net cash proceeds received from certain equity offerings at the redemption price set forth in the Indenture. 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.

The Company issued the 2022 Notes and 2024 Notes pursuant to a single base Indenture among the Company, the Guarantor Subsidiaries, and the Trustee. The Indenture provides, among other things, that the 2022 Notes and 2024 Notes will be senior unsecured obligations of the Company. The Company’s payment obligations under the 2022 Notes and 2024 Notes are fully and unconditionally, as well as jointly 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 agreement, or guarantee certain other indebtedness incurred by the Company or its restricted subsidiaries. The Indenture was supplemented during the first quarter of 2016 to include the changes in Guarantor Subsidiaries noted above.

The Indenture governing the 2022 Notes and 2024 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) pay dividends or make other restricted payments, (ii) make certain investments, (iii) incur additional indebtedness or issue preferred stock, (iv) create liens, (v) pay dividends or make other payments (except for certain dividends and payments to the Company and certain subsidiaries of the Company), (vi) merge or consolidate with other entities or sell substantially all of its assets, (vii) enter into 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 2022 Notes or 2024 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 2022 Notes or 2024 Notes for so long as the 2022 Notes or 2024 Notes are rated investment grade by the two rating agencies.

Interest Rate Swap Agreements — In June 2016, the Company entered into $500 million of long-term interest rate swap agreements to lock into a fixed LIBOR interest rate base. Under the terms of the agreements, $500 million in variable-rate debt was swapped for a weighted average fixed interest rate base of approximately 0.86% for a period of 37 months, beginning on January 31, 2017 and ending on February 28, 2020. The borrowing cost on the swapped principal will range from 2.26% to 2.76% during the life of the swap agreement based on the credit spreads under the Credit Agreement.

Capital Lease Obligations and Other — The Company owes $3.1 million related to capital leases. Capital 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.

Deferred financing costs – As of December 31, 2017, deferred financing costs of $5.1 million and $23.7 million were included in Current portion of long-term debt and Long-term debt, respectively. Deferred financing costs of $6.7 million and $26.6 million were included in Current portion of long-term debt and Long-term debt, respectively, as of December 31, 2016. In connection with the Amended and Restated Credit Agreement, $3.3 million of historical debt issuance costs were written-off in 2017.

Earnings Per Share [Abstract]

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 per share:

	Year Ended December 31,
	2017			2016			2015
	(In millions, except per share data)
Net (loss) income	$	(286.2	)	$	(228.6	)	$	114.9

Weighted average common shares outstanding		57.1			55.7			43.1
Assumed exercise/vesting of equity awards (1)		—			—			0.6
Weighted average diluted common shares outstanding		57.1			55.7			43.7

Net (loss) earnings per basic share	$	(5.01	)	$	(4.10	)	$	2.67
Net (loss) earnings per diluted share	$	(5.01	)	$	(4.10	)	$	2.63

(1)

Incremental shares from equity awards are computed by the treasury stock method. For the years ended December 31, 2017 and 2016, weighted average common shares outstanding is the same for the computations of basic and diluted shares 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 1.6 million, 1.2 million, and 0.7 million for the years ended December 31, 2017, 2016, and 2015, respectively.

The Board of Directors adopted, and the Company’s Stockholders approved, the “TreeHouse Foods, Inc. Equity and Incentive Plan” (the “Plan”). The Plan is administered by our Compensation Committee, which consists entirely of independent directors. The Compensation Committee determines specific awards for our executive officers. For all other employees, if the committee designates, our Chief Executive Officer or such other officers will, from time to time, determine specific persons to whom awards under the Plan will be granted, and the terms and conditions of each award. The Compensation Committee or its designee, pursuant to the terms of the Plan, also will make all other necessary decisions and interpretations under the Plan.

Under the Plan, the Compensation Committee may grant awards of various types of compensation, including stock options, restricted stock, restricted stock units, performance shares, performance units, other types of stock-based awards, and other cash-based compensation. The number of shares authorized to be awarded under the Plan is approximately 16.1 million, of which approximately 5.1 million remain available at December 31, 2017.

(Loss) income before income taxes for the years ended December 31, 2017, 2016, and 2015 includes stock-based compensation expense for employees and directors of $30.0 million, $29.9 million, and $22.9 million, respectively. The tax benefit recognized related to the compensation cost of these share-based awards was approximately $11.1 million, $10.9 million, and 9.5 million for 2017, 2016, and 2015, respectively.

The Company estimates that certain employees and all directors will complete the required service conditions associated with their awards. For all other employees, the Company estimates forfeitures, as not all employees are expected to complete the required service conditions. The expected service period is the longer of the derived service period, as determined from the output of the valuation models, and the service period based on the term of the awards.

Compensation costs related to unvested options totaled $13.5 million at December 31, 2017 and will be recognized over the remaining vesting period of the grants, which averages 1.9 years. The weighted average grant date fair value of options granted in 2017, 2016, and 2015 was $25.56, $25.89, and $22.04, respectively.

Stock options granted under the plan generally have a three year vesting schedule, vest one-third on each of the first three anniversaries of the grant date, and expire ten years from the grant date. Stock options are generally only granted to employees and non-employee directors.

Stock options are valued using the Black-Scholes option pricing model. Expected volatilities for 2017, 2016, and 2015 are based on historical volatilities of the Company’s stock price. The risk-free interest rate for periods within the contractual life of the stock options is based on the U.S. Treasury yield curve in effect at the time of the grant. We based our expected term on the simplified method as described under the SEC Staff Accounting Bulletin No. 107. Under this approach the expected term is 6 years. The assumptions used to calculate the value of the stock option awards granted in 2017, 2016, and 2015 are presented as follows:

	2017			2016			2015
Weighted average expected volatility		26.74	%		25.15	%		25.07	%
Weighted average risk-free interest rate		2.07	%		1.19	%		1.97	%
Expected dividends		0.00	%		0.00	%		0.00	%
Expected term	6.0 years			6.0 years			6.0 years

Restricted Stock Units — Employee restricted stock unit awards generally vest based on the passage of time. These awards generally vest one-third on each anniversary 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. As of December 31, 2017, 100 thousand director restricted stock units have been earned and deferred. The following table summarizes the restricted stock unit activity during the year ended December 31, 2017:

				Weighted					Weighted

Fair value of vested restricted stock units		14.0		16.3		14.9
Tax benefit recognized from vested restricted stock units		5.1		5.7		4.9

Future compensation costs related to restricted stock units are approximately $26.2 million as of December 31, 2017 and will be recognized on a weighted average basis over the next 1.8 years. The grant date fair value of the awards is equal to the Company’s closing stock price on the grant date.

Performance Units — Performance unit awards are granted to certain members of management. These awards contain service and performance conditions. For each of the three performance periods, one-third of the units will accrue, multiplied by a predefined percentage between 0% and 200%, depending on the achievement of certain operating performance measures. Additionally, for the cumulative performance period, a number of units will accrue, equal to the number of units granted multiplied by a predefined percentage 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 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.

During the year ended December 31, 2017, based on achievement of operating performance measures, 72,335 performance units were converted into 81,556 shares of common stock, an average conversion ratio of 1.13 shares for each performance unit.

The following table summarizes the performance unit activity during the year ended December 31, 2017:

	Performance Units			Weighted Average Grant Date Fair Value

Employee Pension and Postretirement Benefit Plans

Compensation And Retirement Disclosure [Abstract]

Employee Pension and Postretirement Benefit Plans

17.	EMPLOYEE PENSION AND POSTRETIREMENT BENEFIT PLANS

Pension and Postretirement Benefits — Certain of our employees and retirees participate in pension and other postretirement benefit plans. In connection with the acquisition of the Private Brands Business, the Company acquired three pension plans and one postretirement benefit plan. The obligations related to these plans were assumed by the Company at the acquisition date. 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.

Defined Contribution Plans — Certain of our 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. For 2017, 2016, and 2015, the Company made matching contributions to the plan of $22.1 million, $18.7 million, and $6.7 million, respectively.

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 partially withdrew from the Western Conference of Teamsters Pension Trust Plan as a result of the closure of our City of Industry, California facility during 2016, which was announced in November 2015. The Company is liable for a share of the plan’s unfunded vested benefits. An estimated partial withdrawal liability of approximately $0.8 million was accrued as of December 31, 2016 and 2017. It will not result in a full withdrawal. No other liabilities were established, as withdrawal from the remaining plans is not probable. In 2017, 2016, and 2015, the contributions to these plans, excluding withdrawal payments, were $3.3 million, $3.2 million, and $1.4 million, respectively.

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 2017 and 2016 is for the plan’s years ended December 31, 2016, and 2015, 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. The Company began participating in the Bakery and Confectionery Union and Industry International Pension Fund and the Retail, Wholesale and Department Store International Union and Industry Pension Fund in 2016 as a result of the acquisition of the Private Brands Business. 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.

Defined Benefit Pension Plans —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. A curtailment charge of $1.4 million was recorded in 2017 reflecting the freeze of several defined benefit pension plans.

A lump sum settlement window was offered to approximately 1,474 terminated, vested participants in the U.S. Pension Plans. This window expired on October 31, 2107 and approximately 59% of these participants accepted the offer. Payments to participants who accepted the offer were made in the fourth quarter of 2017 and totaled $32.8 million. This amount is included in the Benefits paid line of the Change in benefit obligation table below.

The Company’s overall investment strategy is to provide a regular and reliable source of income to meet the liquidity needs of the pension plans and minimize reliance on plan sponsor contributions as a source of benefit security. The Company’s investment policy includes various guidelines and procedures designed to ensure assets are invested in a manner necessary to meet expected future benefits earned by participants. Central to the policy are target allocation ranges by major asset classes. The objective of the target allocations is to ensure the assets are invested with the intent to protect pension plan assets so that such assets are preserved for the provision of benefits to participants and their beneficiaries and such long-term growth as may maximize the amounts available to provide such benefits without undue risk. Additionally, we consider the weighted average return of a capital markets model and historical returns on comparable equity, debt, and other investments. Our current asset mix guidelines, under the investment policy, target equities at 55% to 65% of the portfolio and fixed income at 35% to 45%. At December 31, 2017, our master trust was invested as follows: equity securities of 60.6%, fixed income securities of 39.0%, and cash and cash equivalents of 0.4%. Equity securities primarily include investments in collective equity funds that invest in domestic and international securities, with a primary focus on domestic securities. Fixed income securities primarily include investments in collective funds that invest in corporate bonds of companies from diversified industries. Other investments are short term in nature, including certificates of deposit, investments in a collective bond fund that invests in commercial paper, time deposits, fixed rate notes and bonds, and others.

The fair value of the Company’s pension plan assets at December 31, 2017 and 2016 by asset category is as follows:

	Pension Plan Assets Fair Value Measurements at December 31, (h)

	$	278.7	$	317.6

(a)	This fund is an investment vehicle for cash reserves, which seeks to offer a competitive rate of return through a portfolio of high-grade, short term, and money market instruments. Principal preservation is the primary objective of this fund.

(b)	The primary objective of this fund is to hold a portfolio representative of the overall United States bond and debt market, as characterized by the Barclays Capital Aggregate Bond Index.

(c)	The primary objective of this fund is to approximate the risk and return characteristics of the Dow Jones U.S. ex-LP’s Total Stock Market Index.

(d)	The primary objective of this fund is to approximate the risk and return characteristics of the Morgan Stanley All Country World ex-US (MSCI ACWI ex-US) ND Index. This fund is commonly used to represent the non-U.S. equity in developed and emerging markets.

(e)	The primary objective of this fund is to hold a portfolio representative of the intermediate credit securities portion of the United States bond and debt markets, as characterized by the Barclays Capital U.S. 1-5 year Credit Bond Index.

(f)	The primary objective of this fund is to provide investment results that replicate the overall performance of the MSCI Emerging Markets Index. The Fund may make limited use of futures and/or options to maintain equity exposure.

(g)	The primary objective of this fund is to outperform the Barclay’s Capital High Yield Index over a market cycle while maintaining a similar level of volatility and credit quality as the index. This Fund can serve as a core bond investment position, providing exposure to the U.S. Fixed Income market.

(h)	As the fair values of all of these assets are measured using the net asset value per share practical expedient, levels within the fair value hierarchy are not provided for these assets.

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 2018 contributions to its pension plans will be $1.5 million. The measurement date for the defined benefit pension plans is December 31. In 2017, the actuarial loss relating to the defined benefit pension plans was primarily driven by the change in the discount rate.

Other Postretirement Benefits — 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 2018 contributions to its postretirement benefit plans will be $1.8 million. The measurement date for the other postretirement benefit plans is December 31.

The Company contributes to certain multiemployer postretirement benefit plans other than pensions on behalf of employees covered by collective bargaining agreements. These plans are administered jointly by management and union representatives and cover all eligible retirees. These plans are primarily health and welfare funds and carry the same multiemployer risks as identified at the beginning of this Note. Total contributions to these plans were $0.3 million, $2.8 million, and $2.6 million ended December 31, 2017, 2016, and 2015, respectively. The decline in total contributions from 2016 to 2017 was related to the divestiture of the Soup and Infant Feeding business.

Service cost plus interest cost for the year	$	0.1
1% Decrease:

Service cost plus interest cost for the year	$	(0.1	)

Most of our employees are not eligible for postretirement medical benefits and of those that are, the majority are covered by a multi-employer plan in which expenses are paid as incurred. The effect on those covered by plans for which we maintain a liability was not significant.

Litigation, Investigations, and Audits — On November 16, 2016, a purported TreeHouse shareholder filed a putative 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, 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, Case No. 17-cv-01014, in the Northern District of Illinois, against TreeHouse and certain of its officers. This complaint, like Wells, is 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.

All three 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. 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. The Public Employees’ defendants have filed a motion to dismiss, which has been fully briefed. The next status date for the Public Employees’ matter is set for March 8, 2018.

Additionally, due to the similarity of the complaints, the parties in Wells and Lavin have 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. The next status date in Wells is April 27, 2018. There is no set status date in Lavin at this time.

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.

On October 29, 2017, Mr. Robert Aiken resigned as the Company’s President and Chief Operating Officer. On December 1, 2017, Mr. Aiken filed a demand for arbitration under his employment agreement. Shortly thereafter, the Company filed a counterclaim in arbitration against Mr. Aiken. At this time, no dates have been set for the arbitration and fact discovery has yet to commence.

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, with a bias toward fixed-rate debt.

In June 2016, the Company entered into $500 million of long-term interest rate swap agreements to lock into a fixed LIBOR interest rate base. Under the terms of the agreements, $500 million in variable-rate debt was swapped for a weighted average fixed interest rate base of approximately 0.86% for a period of 37 months, beginning on January 31, 2017 and ending on February 28, 2020. These agreements do not qualify for hedge accounting and changes in their fair value are recorded in the Consolidated Statements of Operations, with their fair value recorded on the Consolidated Balance Sheets.

Foreign Currency Risk — Due to the Company’s foreign operations, we are exposed to foreign currency risk. The Company enters into foreign currency contracts to manage the risk associated with foreign currency cash flows. The Company’s objective in using foreign currency contracts is to establish a fixed foreign currency exchange rate for the net cash flow requirements for purchases that are denominated in U.S. dollars. These contracts do not qualify for hedge accounting and changes in their fair value are recorded in the Consolidated Statements of Operations, with their fair value recorded on the Consolidated Balance Sheets. As of December 31, 2017, the Company had $27.0 million of U.S. dollar foreign currency contracts outstanding, expiring throughout 2018.

Commodity Risk — Certain commodities we use in the production and distribution of our 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, 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 and plastics 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 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, 2017, the Company had outstanding contracts for the purchase of 0.3 million megawatts of electricity, expiring throughout 2018, 2019, and 2020; 8.8 million gallons of diesel, expiring throughout 2018; 3.2 million dekatherms of natural gas, expiring throughout 2018; 0.9 million bushels of corn, expiring throughout 2018.

Cash and cash equivalents and accounts receivable are financial assets with carrying values that approximate fair value. Accounts payable are financial liabilities with carrying values that approximate fair value.

The fair value of the Revolving Credit Facility, Term Loan A, Term Loan A-1, Term Loan A-2, 2022 Notes, 2024 Notes, 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 Revolving Credit Facility, Term Loan A, Term Loan A-1, and Term Loan A-2 were estimated using present value techniques and market based interest rates and credit spreads. The fair values of the Company’s 2022 Notes and 2024 Notes were estimated based on quoted market prices for similar instruments, where the inputs are considered Level 2, due to their infrequent trading volume. 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. The commodity contracts, foreign currency contracts, and interest rate swap agreements are recorded at fair value on the Consolidated Balance Sheets.

The fair value of the investments was determined using Level 1 inputs. Level 1 inputs are quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement dates. The investments are recorded at fair value on the Consolidated Balance Sheets.

Segment Reporting [Abstract]

Segment and Geographic Information and Major Customers

22.	SEGMENT AND GEOGRAPHIC INFORMATION AND MAJOR CUSTOMERS

In the first quarter of 2017, the Company completed changes in its organizational structure that resulted in a change in how the Company manages its business and allocates resources. Our reportable segments are now organized and managed by products: Baked Goods, Beverages, Condiments, Meals, and Snacks. Previously, our reportable segments were organized and managed by customer channels: North American Retail Grocery, Food Away From Home, and Industrial and Export. All prior period information has been recast to reflect this change.

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. Our segments are as follows:

Baked Goods – Our Baked Goods segment sells candy; cookies; crackers; in-store bakery products; pita chips; pretzels; refrigerated dough; and retail griddle waffles, pancakes, and French toast.

Beverages – Our Beverages segment sells broths; liquid non-dairy creamer; non-dairy powdered creamers; powdered drinks; single serve hot beverages; specialty teas, and sweeteners.

Condiments – Our Condiments segment sells aseptic cheese and pudding products; jams, preserves, and jellies; mayonnaise; Mexican, barbeque, and other sauces; pickles and related products; refrigerated and shelf stable dressings and sauces; and table and flavored syrups.

Meals – Our Meals segment sells baking and mix powders; powdered soups and gravies; macaroni and cheese; pasta; ready-to-eat and hot cereals; and skillet dinners. Condensed and ready to serve soup and infant feeding products were sold within the Meals segment through the divestiture of the SIF business on May 22, 2017.

Snacks – Our Snacks segment sells bars; dried fruit; snack nuts; trail mixes; and other wholesome snacks.

The Company evaluates the performance of its segments based on net sales dollars and direct operating income. In conjunction with the change in segments, the Company revised its calculation of direct operating income to include direct general and administrative expenses. Direct operating income is now defined as gross profit less freight out, sales commissions, and direct selling, general, and administrative expenses. All prior period information has been recast to reflect this change. 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 and other operating expense). 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.

The Company’s 2022 Notes and 2024 Notes are guaranteed fully and unconditionally, as well as jointly and severally, by its Guarantor Subsidiaries. The guarantees of the Guarantor Subsidiaries are subject to release in limited circumstances, only upon the occurrence of certain customary conditions. There are no significant restrictions on the ability of the parent company or any guarantor to obtain funds from its subsidiaries by dividend or loan. The following supplemental consolidating financial information presents the results of operations, financial position, and cash flows of the parent company, its Guarantor Subsidiaries, its non-guarantor subsidiaries and the eliminations necessary to arrive at the information for the Company on a consolidated basis as of December 31, 2017 and 2016, and for the years ended December 31, 2017, 2016, and 2015. The equity method has been used with respect to investments in subsidiaries. The principal elimination entries eliminate investments in subsidiaries and intercompany balances and transactions.

Battle Creek Full Closure

On January 31, 2018, the Company announced its intention to close its remaining operations in Battle Creek Michigan. In November 2016, the Company announced its initial decision to downsize the Battle Creek facility. Following completion of the first phase of downsizing, it was determined that the remaining operations would not be economically viable. Current production at Battle Creek will be moved to other cereal manufacturing facilities. The decision is consistent with the August 2017 announcement of TreeHouse 2020. The costs to close the remainder of the Battle Creek facility are expected to be approximately $15.2 million, of which approximately $8.8 million is expected to be in cash. Components of the charges include non-cash asset write-offs of approximately $6.4 million, employee-related costs of approximately $2.4 million, and other closure costs of approximately $6.4 million. Total expected costs to close decreased $14.8 million since the initial announcement due to revised estimates.

Visalia Facility Closure

On February 15, 2018, the Company announced the planned closure of its Visalia, California facility by the end of the first quarter of 2019. The plant primarily produces pretzels and cereal snack mixes for the Baked Goods segment. Current pretzel production will be moved to other TreeHouse manufacturing facilities prior to the plant closure. The decision is consistent with the August 2017 announcement of TreeHouse 2020. The costs to close the Visalia facility are expected to be approximately $21 million, of which approximately $8 million is expected to be in cash. Components of the charges include non-cash asset write-offs of approximately $13 million, employee-related costs of approximately $3 million, and other closure costs of approximately $5 million.

Summary of Significant Accounting Policies (Policies)

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. Certain prior year amounts in the Consolidated Statements of Cash Flows have been reclassified to conform to the current period presentation.

In the first quarter of 2017, the Company completed changes in its organizational structure that resulted in a change in how the Company manages its business and allocates resources. As a result, the Company revised its reportable segments to reflect how management currently reviews financial information and allocates resources. See Note 22 for additional details. All prior period amounts have been recast to reflect the change in reportable segments.

On February 1, 2016, the Company acquired all of the outstanding common stock of Ralcorp Holdings, Inc., the Missouri corporation through which the private brands business of ConAgra Foods, Inc. (“Private Brands Business”) was operated. Ralcorp Holdings, Inc. was renamed TreeHouse Private Brands, Inc. during the first quarter of 2016. The results of operations of the Private Brands Business are included in our financial statements from the date of acquisition and are included in the Baked Goods, Condiments, Meals, and Snacks segments, as applicable.

The Private Brands Business was on a 4-4-5 fiscal calendar during the first three quarters of 2016, which resulted in differences between the fiscal quarter ends of the Private Brands Business and the Company. In the fourth quarter of 2016, the Company changed the fiscal year end of the Private Brands Business to December 31. This change in reporting period for the Private Brands Business represents a change in accounting principle that is preferable as it provides more timely and relevant financial information to the users of its financial statements and eliminates the previously existing difference in reporting periods. The Company determined that it was impracticable to retrospectively apply this change to the first three quarters of 2016 as the data to determine the cumulative effect of the change was not available and cannot be prepared. Therefore, the Company reported the change in accounting principle prospectively in net income for the three months ended December 31, 2016 and did not retrospectively apply the effects of this change in prior periods, the cumulative effect of which the Company believes would be immaterial in all periods.

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, 2017 and 2016, $49.4 million and $61.9 million, respectively, represents cash and equivalents held in foreign jurisdictions, in local currencies, that are convertible into other currencies. The cash and equivalents held in foreign jurisdictions are expected to be used for general corporate purposes in foreign jurisdictions, including capital projects and acquisitions. The Prepaid expenses and other current assets line on the Consolidated Balance Sheets also includes restricted cash of $2.7 million as of December 31, 2017, which relates to cash held to meet certain insurance requirements.

Inventories

Inventories — Inventories are stated at the lower of cost or market. Pickle inventories are valued using the LIFO method and a portion of our snack nuts inventories are valued using the weighted average costing approach, while all of our other inventories are 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:

Asset		Useful Life
Buildings and improvements		12-40 years
Machinery and equipment		3-15 years
Office furniture and equipment		3-12 years

We perform impairment tests when circumstances indicate that the carrying value of an asset may not be recoverable. Capitalized 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:

Asset		Useful Life
Customer relationships		5 to 20 years
Trademarks		10 to 20 years
Non-competition agreements		Based on the terms of the agreements
Deferred financing costs associated with line-of-credit arrangements		Based on the terms of the agreements
Formulas/recipes		5 to 7 years
Computer software		2 to 7 years

All amortization expense related to intangible assets is recorded in the Amortization expense line of 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 publically 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.

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. See Note 15.

Revenue Recognition

Revenue Recognition — Sales are recognized when persuasive evidence of an arrangement exists, the price is fixed or determinable, title and risk of loss transfer to the customer, and there is a reasonable assurance of collection of the sales proceeds. Product is shipped FOB shipping point or FOB destination, depending on our agreement with the customer. Sales are reduced by certain sales incentives, some of which are recorded by estimating expense based on our historical experience.

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.

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 are included in Other income, net in the Consolidated Statements of Operations.

Shipping and Handling Fees

Shipping and Handling Fees — Our shipping and handling costs are included in both cost of sales and selling and distribution expense, depending on the nature of such costs. Shipping and handling costs included in cost of sales reflect inventory warehouse costs, product loading and handling costs, and costs associated with transporting finished products from our manufacturing facilities to distribution warehouses. Shipping and handling costs included in selling and distribution expense consist primarily of the cost of shipping products to customers through third party carriers. Shipping and handling costs recorded as a component of selling and distribution expense were approximately $220.8 million, $198.8 million, and $87.2 million for the years ended December 31, 2017, 2016, and 2015, respectively.

Derivative Financial Instruments

Derivative Financial Instruments — From time to time, we utilize derivative financial instruments including interest rate and commodity swaps, foreign currency contracts, and forward purchase contracts to manage our exposure to interest rate, foreign currency, and commodity price risks. We do not hold or issue financial instruments for speculative or trading purposes. The Company accounts for its derivative instruments as either assets or liabilities and carries them at fair value. Derivatives that are not designated as hedges according to GAAP must be adjusted to fair value through earnings. For derivative instruments that are designated as cash flow hedges, the effective portion of the gain or loss is reported as Accumulated other comprehensive loss and reclassified into earnings in the same period when the hedged transaction affects earnings. The ineffective gain or loss is recognized in current earnings. Commodity forward contracts 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 further information about our derivative instruments, see Note 20.

Capital Lease Obligations

Capital Lease Obligations — Capital lease obligations represent machinery and equipment financing obligations, which are generally payable in monthly installments of principal and interest, and are collateralized by the related assets financed.

Insurance Accrual

Insurance Accruals — We retain selected levels of property and casualty risks, primarily related to employee health care, workers’ compensation claims, and other casualty losses. Many of these potential losses are covered under conventional insurance programs with third party carriers having high deductible limits. In other areas, we are self-insured with stop-loss coverage. Accrued liabilities for incurred but not reported losses related to these retained risks are calculated based upon loss development factors that consider a number of elements, including claims history and expected trends. We develop these accruals with external insurance brokers and actuaries.

Facility Closing and Reorganization Costs

Facility Closing and Reorganization Costs — We periodically record facility closing and reorganization charges when we have identified a facility for closure or other reorganization opportunity, developed a plan, and notified the affected employees. These charges are incurred as a component of operating (loss) income. See Note 3 for more information.

Research and Development Costs

Research and Development Costs — We record research and development charges to expense as they are incurred and report them in the General and administrative expense line of our Consolidated Statements of Operations. Expenditures totaled $30.8 million, $29.6 million, and $14.3 million for the years ended December 31, 2017, 2016, and 2015, respectively.

Advertising Costs

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

Summary of Effect of Share-Based Compensation Awards on Weighted Average Number of Shares Outstanding Used in Calculating Diluted Earnings Per Share

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 per share:

	Year Ended December 31,
	2017			2016			2015
	(In millions, except per share data)

Incremental shares from equity awards are computed by the treasury stock method. For the years ended December 31, 2017 and 2016, weighted average common shares outstanding is the same for the computations of basic and diluted shares 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 1.6 million, 1.2 million, and 0.7 million for the years ended December 31, 2017, 2016, and 2015, respectively.

[1]	The Company acquired the Private Brands Business on February 1, 2016.
[2]	(1)Incremental shares from equity awards are computed by the treasury stock method. For the years ended December 31, 2017 and 2016, weighted average common shares outstanding is the same for the computations of basic and diluted shares 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 1.6 million, 1.2 million, and 0.7 million for the years ended December 31, 2017, 2016, and 2015, respectively.
[3]	Due to rounding and the fluctuations in shares, the sum of the four quarters may not be the same as the total for the year.
