Accounting Policies [Abstract]
Basis of Presentation	1. BASIS OF PRESENTATION The unaudited Condensed Consolidated Financial Statements included herein have been prepared by TreeHouse Foods, Inc. and its consolidated subsidiaries (the “Company,” “TreeHouse,” “we,” “us,” or “our”), pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) applicable to quarterly reporting on Form 10-Q. In our opinion, these statements include all adjustments necessary for a fair presentation of the results of all interim periods reported herein. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted as permitted by such rules and regulations. Certain prior year amounts in the Condensed Consolidated Statements of Cash Flows have been reclassified to conform to the current period presentation. The Condensed Consolidated Financial Statements and related notes should be read in conjunction with the Consolidated Financial Statements and related notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016. Results of operations for interim periods are not necessarily indicative of annual results. 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 makes operating decisions. See Note 18 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 (“Private Brands Business”) of ConAgra Foods, Inc. 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 third quarter of 2016, and September 25, 2016 was the fiscal period end closest to the Company’s fiscal quarter end. This difference did not have a significant impact on the results of operations of the Private Brands Business. In the fourth quarter of 2016, the Company changed the fiscal year end of the Private Brands Business to December 31. The Company did not retrospectively apply the effects of this change to the three and nine month periods ended September 30, 2016 due to impracticability, and believes the effects would be immaterial. The preparation of our Condensed Consolidated Financial Statements in conformity with GAAP requires us to use our 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 Condensed Consolidated Financial Statements, and the reported amounts of net sales and expenses during the reporting period. Actual results could differ from these estimates. A detailed description of the Company’s significant accounting policies can be found in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Restructuring And Related Activities [Abstract]
Restructuring and Margin Improvement Activities	2. 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. During the three months ended September 30, 2017, the Company recorded total charges $20.7 million across all restructuring programs and margin improvement activities. The charges included $10.2 million recorded in Cost of sales and $10.5 million recorded in Other operating expenses, net. During the three months ended September 30, 2016, the Company recorded total charges of $5.9 million across all restructuring programs and margin improvement activities. The charges included $1.0 million recorded in Cost of sales and $4.9 million recorded in Other operating expenses, net. During the nine months ended September 30, 2017, the Company recorded charges of $39.5 million across all restructuring programs and margin improvement activities. These charges included $13.5 million recorded in Cost of sales and $26.0 million recorded in Other operating expenses, net. During the nine months ended September 30, 2016, the Company recorded charges of $12.9 million across all restructuring programs and margin improvement activities. These charges included $3.9 million recorded in Cost of sales and $9.0 million recorded in Other operating expenses, net. 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 activities costs by reportable segment has not been presented. See Note 18 for more information. TreeHouse 2020 In the third quarter of 2017, the Company announced TreeHouse 2020, a program intended to accelerate long-term growth through optimization of our manufacturing network, transformation of our mixing centers and warehouse footprint, and leveraging of systems and processes to drive performance. 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. Production at the Brooklyn Park, Minnesota and Plymouth, Indiana facilities is expected to cease in the fourth quarter of 2017. The facility downsizing at Dothan, Alabama is expected to be complete in the third quarter of 2018. In addition, we have taken steps toward increasing our capacity utilization, operational margin expansion, and streamlining our plant structure to optimize our supply chain. Below is a summary of costs by type associated with TreeHouse 2020: Three Nine Months Ended Cumulative Costs Total Expected September 30, 2017 September 30, 2017 To Date Costs (In millions) Asset-related $ 8.0 $ 8.0 $ 8.0 $ 14.8 Employee-related 4.3 4.3 4.3 7.0 Other costs 2.4 2.4 2.4 22.7 Total $ 14.7 $ 14.7 $ 14.7 $ 44.5 For the three months ended September 30, 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 Restructuring and Plant Closing Costs The Company continually analyzes its plant network to align operations with the current and future needs of its customers. Facility closure decisions are made when the Company identifies opportunities to lower production costs or eliminate excess manufacturing capacity while maintaining a competitive cost structure, service levels, and product quality. Expenses associated with facility closures are primarily aggregated in 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 key information regarding the Company’s announced facility closures is outlined in the table below.

Total expected costs to close the City of Industry, California, Ayer, Massachusetts, Ripon, Wisconsin, and Delta, British Columbia facilities have been reduced by approximately $4.9 million, $0.6 million, $1.2 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 $4.6 million and $0.9 million, respectively, since their initial announcement. Below is a summary of the plant closing costs by type of cost: Three Nine Months Ended September 30, Cumulative Costs Total Expected 2017 2016 2017 2016 To Date Costs (In millions) Asset-related $ 0.8 $ 1.0 $ 4.3 $ 2.5 $ 14.5 $ 16.6 Employee-related 0.2 2.2 2.9 4.1 10.2 11.9 Other closure costs 1.9 2.7 12.2 3.8 16.7 18.8 Total $ 2.9 $ 5.9 $ 19.4 $ 10.4 $ 41.4 $ 47.3 For the three months ended September 30, 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 $3.1 million for the three months ended September 30, 2017 and $5.4 million for the nine months ended September 30, 2017 and were primarily the result of a Private Brands plant closure initiated prior to TreeHouse’s acquisition. Other cost reduction activities were insignificant for the three months ended September 30, 2016 and $2.5 million for the nine months ended September 30, 2016. Liabilities recorded as of September 30, 2017 associated with total exit cost reserves relate to severance, the partial withdrawal from a multiemployer pension plan, and lease termination costs. The severance and lease termination liabilities were included in the Accounts payable and accrued expenses line of the Condensed Consolidated Balance Sheets, while the multiemployer pension plan withdrawal liability was included in the Other long-term liabilities line of the Condensed Consolidated Balance Sheets. The table below presents a reconciliation of the liabilities as of September 30, 2017: Severance Multiemployer Plan Other Costs Total Liabilities (In millions) Balance as of December 31, 2016 $ 3.5 $ 0.8 $ - $ 4.3 Expense 6.6 — 2.4 9.0 Payments (4.2 ) — (0.5 ) (4.7 ) Adjustments (0.3 ) — — (0.3 ) Balance as of September 30, 2017 $ 5.6 $ 0.8 $ 1.9 $ 8.3

Business Combinations [Abstract]
Acquisitions	3 . 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 Private Brands Business acquisition was accounted for under the acquisition method of accounting and the results of operations were included in our Condensed Consolidated Financial Statements from the date of acquisition in the Baked Goods, Condiments, Meals, and Snacks segments. Included in the Company’s Condensed Consolidated Statements of Operations are the Private Brands Business’s net sales of approximately $2,074.6 million and income before income taxes of $55.6 million from the date of acquisition through September 30, 2016. Integration costs of $7.5 million, which were included in the Cost of sales and General and administrative expense lines of the Condensed Consolidated Statements of Operations, were included in determining income before income taxes. We have completed the purchase price allocation 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 Customer relationships 510.9 Trade names 33.0 Software 19.6 Formulas 23.2 Other assets 50.2 Goodwill 1,141.2 Assets acquired 3,237.4 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 $555.0 million, $73.3 million, $413.8 million, and $97.9 million of goodwill to the Baked Goods, 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 Condensed 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. Since the preliminary purchase price allocation included in the Company’s Annual Report for the fiscal year ended December 31, 2016, the Company recorded purchase price adjustments related to taxes, resulting in an increase to goodwill of approximately $3.0 million in the first quarter of 2017. These adjustments did not impact the Condensed Consolidated Statements of Operations. 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, 2016. 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 were $35.2 million of costs incurred by the Company in connection with the acquisition. 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. Nine September 30, 2016 (In millions, except per share data) Pro forma net sales $ 4,722.4 Pro forma net income $ 74.9 Pro forma basic earnings per common share $ 1.32 Pro forma diluted earnings per common share $ 1.30

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	6. GOODWILL AND INTANGIBLE ASSETS 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 18 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.

Income Tax Disclosure [Abstract]
Income Taxes	8. INCOME TAXES Income taxes were recorded at an effective rate of 4.3% and (65.2)% for the three and nine months ended September 30, 2017, respectively, compared to 28.9% and 24.0% for the three and nine months ended September 30, 2016, respectively. The changes in the effective tax rates for the three and nine months ended September 30, 2017 compared to September 30, 2016 was primarily a result of the income tax benefits related to share-based payments, the income tax benefit from the release of reserves for unrecognized tax benefits, and the income tax benefit derived from foreign tax credits. Our effective tax rate may change from period to period based on recurring and non-recurring factors including the jurisdictional mix of earnings, enacted tax legislation, state income taxes, settlement of tax audits, and the expiration of the statute of limitations in relation to unrecognized tax benefits. The Company’s effective tax rate differs from the U.S. federal statutory tax rate primarily due to state tax expense, the benefits associated with the federal domestic production activities deduction, and an intercompany financing structure entered into in conjunction with the E.D. Smith Foods, Ltd. (“E.D. Smith”) acquisition in 2007. In addition, the Company’s effective tax rate for the nine months ended September 30, 2017 reflects a discrete benefit of approximately 17.7% attributable to the vesting and exercise of share-based awards. 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 2017 or 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 2017 and 2018. Management estimates that it is reasonably possible that the total amount of unrecognized tax benefits could decrease by as much as $9.2 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 $1.5 million of the $9.2 million would affect net income when settled.

The Amended and Restated Credit Agreement (1) amended the maturity dates of the Revolving Credit Facility, Term Loan A, and Term Loan A-1 so that they are conterminous and mature on February 1, 2021, (2) provided for the issuance of Term Loan A-2, and (3) increased credit spreads. The proceeds from Term Loan A-2 were used to fund a portion of the purchase price of the Private Brands Business. After satisfying all of the required collateral release conditions set forth in the Credit Agreement, the Credit Facility became unsecured in August 2017. Amongst other conditions, the Company had to reach a leverage ratio of 3.5 as defined in the Credit Agreement and have no other pari-passu secured debt outstanding to become unsecured. The Revolving Credit Facility, Term Loan A, Term Loan A-1, and Term Loan A-2 are known collectively as the “Amended and Restated Credit Agreement.” The Company’s average interest rate on debt outstanding under its Amended and Restated Credit Agreement for the three months ended September 30, 2017 was 3.106%. Including the interest rate swap agreements described below with a weighted average fixed interest rate base of approximately 0.86% on $500 million, the average rate decreases to 2.99%. Revolving Credit Facility — As of September 30, 2017, $729.5 million of the aggregate commitment of $900 million of the Revolving Credit Facility was available. Under the Amended and Restated Credit Agreement, the Revolving Credit Facility matures on February 1, 2021. In addition, as of September 30, 2017, there were $50.5 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.

Earnings Per Share [Abstract]
Earnings Per Share	10. 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: Three Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 (In millions, except per share data) Net income $ 28.8 $ 37.4 $ 22.8 $ 53.2 Weighted average common shares outstanding 57.3 56.8 57.1 55.4 Assumed exercise/vesting of equity awards (1) 0.4 0.8 0.6 0.8 Weighted average diluted common shares outstanding 57.7 57.6 57.7 56.2 Net earnings per basic share $ 0.50 $ 0.66 $ 0.40 $ 0.96 Net earnings per diluted share $ 0.50 $ 0.65 $ 0.40 $ 0.95 (1) Incremental shares from equity awards are computed using the treasury stock method. Equity awards, excluded from our computation of diluted earnings per share because they were anti-dilutive, were 1.7 million and 1.4 million for the three and nine months ended September 30, 2017, respectively, and 0.4 million and 0.7 million for the three and nine months ended September 30, 2016, respectively.

Stock-Based Compensation	11. STOCK-BASED COMPENSATION The Board of Directors adopted, and the Company’s stockholders approved, the “TreeHouse Foods, Inc. Equity and Incentive Plan” (the “Plan”). On April 27, 2017, the Plan was amended and restated to increase the number of shares available for issuance under the Plan by 3.8 million shares, effective February 14, 2017. 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, will also 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 maximum number of shares available to be awarded under the Plan is approximately 16.1 million, of which approximately 4.9 million remain available at September 30, 2017. Income before income taxes for the three and nine month periods ended September 30, 2017 includes stock-based compensation expense of $6.6 million and $25.2 million, respectively. Stock-based compensation expense for the three and nine months ended September 30, 2016 was $8.5 million and $22.8 million, respectively. The tax benefit recognized related to the compensation cost of these share-based awards was approximately $2.4 million and $9.3 million for the three and nine months ended September 30, 2017, respectively, and $3.1 million and $8.3 million for the three and nine months ended September 30, 2016, respectively. Stock Options — The following table summarizes stock option activity during the nine months ended September 30, 2017. Stock options generally vest in approximately three equal installments on each of the first three anniversaries of the grant date, and expire ten years from the grant date.

The Company uses the Black-Scholes option pricing model to value its stock option awards. The assumptions used to calculate the fair value of stock options issued in 2017 include the following: weighted average expected volatility of 26.71%, expected term of six years, weighted average risk free rate of 2.07%, and no dividends. The weighted average grant date fair value of awards granted in 2017 was $24.41. Restricted Stock Units — Employee restricted stock unit awards generally vest based on the passage of time. These awards generally vest in approximately three equal installments on each of the first three anniversaries of the grant date. Director restricted stock units generally 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 September 30, 2017, 100 thousand director restricted stock units have been earned and deferred.

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, generally, on the third anniversary of the grant date. The Company intends to settle these awards in stock and has the shares available to do so. On June 27, 2017, based on an achievement of operating performance measures, 72,335 performance units were converted into 81,556 shares of stock, an average conversion of 1.13 shares for each performance unit.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Instruments	16. DERIVATIVE INSTRUMENTS The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by derivative instruments include interest rate risk, foreign currency risk, 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. 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 Condensed Consolidated Statements of Operations, with their fair value recorded on the Condensed Consolidated Balance Sheets. 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 Condensed Consolidated Statements of Operations, with their fair value recorded on the Condensed Consolidated Balance Sheets. As of September 30, 2017, the Company had $46.5 million of U.S. dollar foreign currency contracts outstanding, expiring throughout 2018. 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 Condensed Consolidated Balance Sheets, with changes in value being recorded in the Condensed 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 September 30, 2017, the Company had outstanding contracts for the purchase of 66,473 megawatts of electricity, expiring throughout 2017 and 2018; 8.8 million gallons of diesel, expiring throughout 2017 and early 2018; 1.9 million dekatherms of natural gas, expiring throughout 2017 and 2018; 0.1 million bushels of wheat, expiring throughout 2017 and early 2018; and 0.9 million bushels of corn, expiring throughout 2017 and early 2018.

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 Condensed 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 Condensed Consolidated Balance Sheets.

Segment Reporting [Abstract]
Segment and Geographic Information and Major Customers	18. 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 to the Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended December 31, 2016. Financial information relating to the Company’s reportable segments is as follows: Three Months Ended Nine Months Ended September 30, September 30, 2017 2016 2017 2016 (In millions) (In millions) Net sales to external customers: Baked Goods $ 351.2 $ 329.4 $ 1,016.6 $ 871.8 Beverages 244.9 234.9 759.1 672.7 Condiments 333.8 322.9 988.8 959.0 Meals 284.6 347.9 897.0 937.3 Snacks 332.6 351.7 940.2 967.5 Unallocated 1.7 0.1 5.5 (9.8 ) Total $ 1,548.8 $ 1,586.9 $ 4,607.2 $ 4,398.5 Direct operating income: Baked Goods $ 46.9 $ 33.8 $ 121.3 $ 97.4 Beverages 51.7 63.8 170.7 175.6 Condiments 34.4 38.0 102.2 115.0 Meals 32.1 33.1 99.9 88.9 Snacks 1.8 18.5 24.4 47.3 Total 166.9 187.2 518.5 524.2 Unallocated selling, general, and administrative expenses (66.0 ) (74.3 ) (228.1 ) (254.2 ) Unallocated cost of sales (1) (5.2 ) (1.5 ) 3.2 (20.8 ) Unallocated corporate expense and other (37.9 ) (33.8 ) (192.2 ) (101.0 ) Operating income 57.8 77.6 101.4 148.2 Other expense (27.7 ) (25.0 ) (87.6 ) (78.2 ) Income before income taxes $ 30.1 $ 52.6 $ 13.8 $ 70.0 (1) Includes charges related to restructuring and margin improvement activities, and other costs managed at corporate.
