Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background	Post Holdings, Inc. (“Post” or the “Company”) is a consumer packaged goods holding company operating in the center-of-the-store, foodservice, food ingredient, refrigerated, active nutrition and private brand food categories. The Company’s products are sold through a variety of channels such as grocery, club and drug stores, mass merchandisers, foodservice, ingredient and via the internet. Post operates in four reportable segments: Post Consumer Brands, Michael Foods Group, Active Nutrition and Private Brands. The Post Consumer Brands segment primarily consists of the ready-to-eat (“RTE”) cereal business, the Michael Foods Group segment includes predominantly foodservice and food ingredient egg, potato and pasta businesses and a retail cheese business, the Active Nutrition segment includes protein shakes, bars and powders and nutritional supplements and the Private Brands segment primarily consists of peanut and other nut butters, dried fruit and nuts and granola. On February 6, 2012, Post common stock began trading on the New York Stock Exchange under the ticker symbol “POST.” Unless otherwise stated or the context otherwise indicates, all references in this Form 10-K to “Post,” “the Company,” “us,” “our” or “we” mean Post Holdings, Inc. and its consolidated subsidiaries. Certain prior year amounts have been reclassified to conform with the 2016 presentation. These reclassifications had no impact on Net Loss or Shareholders’ Equity, as previously reported.

Summary of Significant Accounting Policies	Sep. 30, 2016
Accounting Policies [Abstract]
Summary of Signifcant Accounting Policies	Principles of Consolidation — The consolidated financial statements include the operations of Post Holdings, Inc. and its wholly-owned subsidiaries. All intercompany transactions have been eliminated. Use of Estimates and Allocations — The consolidated financial statements of the Company are prepared in conformity with accounting principles generally accepted in the United States of America, which require certain elections as to accounting policy, estimates and assumptions that affect the reported amounts of assets, liabilities, the disclosure of contingent liabilities at the dates of the financial statements and the reported amount of net revenues and expenses during the reporting periods. Significant accounting policy elections, estimates and assumptions include, among others, pension and benefit plan assumptions, valuation assumptions of goodwill and other intangible assets, marketing programs, self insurance reserves and income taxes. Actual results could differ from those estimates. Business Combinations — The Company uses the acquisition method in accounting for acquired businesses. Under the acquisition method, our financial statements reflect the operations of an acquired business starting from the completion of the acquisition. The assets acquired and liabilities assumed are recorded at their respective estimated fair values at the date of the acquisition. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill. Cash Equivalents — Cash equivalents include all highly liquid investments with original maturities of less than three months. Restricted Cash — Restricted cash includes items such as cash deposits which serve as collateral for certain commodity hedging contracts as well as the Company's high deductible workers’ compensation insurance program. In addition, restricted cash includes deposits with third party escrow agents in connection with a recently announced acquisition that will be credited against the purchase price when the transaction closes. Receivables — Receivables are reported at net realizable value. This value includes appropriate allowances for doubtful accounts, cash discounts, and other amounts which the Company does not ultimately expect to collect. The Company determines its allowance for doubtful accounts based on historical losses as well as the economic status of, and its relationship with its customers, especially those identified as “at risk.” A receivable is considered past due if payments have not been received within the agreed upon invoice terms. Receivables are written off against the allowance when the customer files for bankruptcy protection or is otherwise deemed to be uncollectible based upon the Company’s evaluation of the customer’s solvency. Inventories — Inventories, other than flocks, are generally valued at the lower of average cost (determined on a first-in, first-out basis) or market. Reported amounts have been reduced by an allowance for obsolete product and packaging materials based on a review of inventories on hand compared to estimated future usage and sales. Flock inventory represents the cost of purchasing and raising chicken flocks to egg laying maturity. The costs included in our flock inventory include the costs of the chicks, the feed fed to the birds and the labor and overhead costs incurred to operate the pullet facilities until the birds are transferred into the laying facilities, at which time their cost is amortized to operations, as cost of goods sold, over their expected useful lives of one to two years. Restructuring Expenses and Assets Held For Sale — Restructuring charges principally consist of severance, accelerated stock compensation and other employee separation costs, accelerated depreciation and certain long-lived asset impairments. The Company recognizes restructuring obligations and liabilities for exit and disposal activities at fair value in the period the liability is incurred. Employee severance costs are expensed when they become probable and reasonably estimable under established severance plans. Depreciation expense related to assets that will be disposed of or idled as a part of the restructuring activity is accelerated through the expected date of the asset shut down. Assets are classified as held for sale if the Company has committed to a plan for selling the assets, is actively and reasonably marketing them, and sale is reasonably expected within one year. The carrying value of assets held for sale is included in “Prepaid expenses and other current assets” on the Consolidated Balance Sheets. See Note 4 for information about restructuring expenses and assets held for sale. Property — Property is recorded at cost, and depreciation expense is generally provided on a straight-line basis over the estimated useful lives of the properties. Estimated useful lives range from 1 to 20 years for machinery and equipment and 3 to 40 years for buildings, building improvements and leasehold improvements, and 1 to 5 years for software. Total depreciation expense was $150.2 , $131.1 and $85.0 in fiscal 2016 , 2015 and 2014 , respectively. Any gains and losses incurred on the sale or disposal of assets are included in "Other operating expenses, net” in the Consolidated Statements of Operations. Repair and maintenance costs incurred in connection with on-going and planned major maintenance activities are accounted for under the direct expensing method. During the year ended September 30, 2015, the Company had non-monetary exchanges of fixed assets. The cash and non-cash portions of these transactions were $9.8 and $12.6 , respectively. Property consisted of: September 30, 2016 2015 Land and land improvements $ 58.0 $ 52.8 Buildings and leasehold improvements 618.2 591.3 Machinery and equipment 1,094.5 1,006.4 Software 50.4 49.2 Construction in progress 79.2 38.0 1,900.3 1,737.7 Accumulated depreciation (545.9 ) (404.5 ) $ 1,354.4 $ 1,333.2 Other Intangible Assets — Other intangible assets consist primarily of customer relationships and trademarks/brands acquired in business combinations and includes both indefinite and definite-lived assets. Amortization expense related to definite-lived intangible assets, which is provided on a straight-line basis over the estimated useful lives of the assets, was $152.6 , $141.7 , and $70.8 in fiscal 2016 , 2015 and 2014 , respectively. For the definite-lived intangible assets recorded as of September 30, 2016 , amortization expense of $152.6 , $152.6 , $151.7 , $151.7 and $151.7 is scheduled for fiscal 2017 , 2018 , 2019 , 2020 and 2021 , respectively. Other intangible assets consisted of: September 30, 2016 September 30, 2015 Carrying Amount Accum. Amort. Net Amount Carrying Amount Accum. Amort. Net Amount Subject to amortization: Customer relationships $ 2,012.7 $ (302.0 ) $ 1,710.7 $ 1,998.6 $ (192.7 ) $ 1,805.9 Trademarks/brands 795.1 (120.6 ) 674.5 780.9 (79.1 ) 701.8 Other 21.7 (7.7 ) 14.0 21.3 (5.4 ) 15.9 2,829.5 (430.3 ) 2,399.2 2,800.8 (277.2 ) 2,523.6 Not subject to amortization: Trademarks/brands 434.5 — 434.5 445.7 — 445.7 $ 3,264.0 $ (430.3 ) $ 2,833.7 $ 3,246.5 $ (277.2 ) $ 2,969.3 Recoverability of Assets — The Company continually evaluates whether events or circumstances have occurred which might impair the recoverability of the carrying value of its assets, including property, identifiable intangibles and goodwill. Trademarks with indefinite lives are reviewed for impairment during the fourth quarter of each fiscal year following the annual forecasting process, or more frequently if facts and circumstances indicate the trademark may be impaired. The trademark impairment tests require us to estimate the fair value of the trademark and compare it to its carrying value. The estimated fair value is determined using an income-based approach (the relief-from-royalty method), which requires significant assumptions for each brand, including estimates regarding future revenue growth, discount rates, and appropriate royalty rates. Assumptions are determined after consideration of several factors for each brand, including profit levels, research of external royalty rates by third party experts and the relative importance of each brand to the Company. Revenue growth assumptions are based on historical trends and management’s expectations for future growth by brand. The discount rate is based on a weighted-average cost of capital utilizing industry market data of similar companies. In addition, definite-lived assets and indefinite-lived intangible assets are reassessed as needed when information becomes available that is believed to negatively impact the fair market value of an asset. In general, an asset is deemed impaired and written down to its fair value if estimated related future cash flows are less than its carrying amount. See Note 6 for information about goodwill impairments. For the year ended September 30, 2016, the Company conducted an impairment review and concluded there was no impairment of intangible assets as of September 30, 2016. At September 30, 2016, the estimated fair values of all intangible assets exceeded their carrying value by at least 36% . At September 30, 2015, Post recorded impairment losses in the Post Consumer Brands Segment of $3.7 for the Grape-Nuts brand and $0.1 for the 100% Bran brand to record these trademarks at their estimated current fair values of $11.2 and zero , respectively. Due to repeated past impairments, continued weakness in the brand forecasts and a lack of sales growth from recent brand support efforts, as of October, 1 2015, the Grape-Nuts brand was converted to a definite-lived asset and assigned a 20 year useful life. At September 30, 2014, Post recorded impairment losses in the Post Consumer Brands segment of $34.4 for the Post brand, $23.0 for the Honey Bunches of Oats brand, $17.2 for the Post Shredded Wheat brand and $8.4 for the Grape-Nuts brand to record these trademarks at their estimated current fair values of $144.0 , $243.9 , $8.2 and $14.9 , respectively. Due to repeated past impairments, continued weakness in the brand forecasts and a lack of sales growth from recent brand support efforts, as of October 1, 2014, the Post Shredded Wheat brand was converted to a definite-lived asset and assigned a 20 year useful life. These fair value measurements fell within Level 3 of the fair value hierarchy as described in Note 13. The trademark and goodwill impairment losses are reported in “Impairment of goodwill and other intangible assets” on the Consolidated Statements of Operations. Investments — The Company funds a portion of its deferred compensation liability by investing in certain mutual funds in the same amounts as selected by the participating employees. Because management’s intent is to invest in a manner that matches the deferral options chosen by the participants and those participants can elect to transfer amounts in or out of each of the designated deferral options at any time, these investments have been classified as trading assets and are stated at fair value in “Prepaid expenses and other current assets” and “Other Assets” (see Note 13). Both realized and unrealized gains and losses on these assets are included in “Selling, general and administrative expenses” and offset the related change in the deferred compensation liability. Revenue — Revenue is recognized when title of goods and risk of loss is transferred to the customer, as specified by the shipping terms. Net sales reflect gross sales, including amounts billed to customers for shipping and handling, less sales discounts and trade allowances (including promotional price buy downs and new item promotional funding). Customer trade allowances are generally computed as a percentage of gross sales. Products are generally sold with no right of return except in the case of goods which do not meet product specifications or are damaged, and related reserves are maintained based on return history. If additional rights of return are granted, revenue recognition is deferred. Estimated reductions to revenue for customer incentive offerings are based upon customer redemption history. Cost of Goods Sold — Cost of goods sold includes, among other things, inbound and outbound freight costs and depreciation expense related to assets used in production, while storage and other warehousing costs are included in “Selling, general and administrative expenses.” Storage and other warehousing costs totaled $ 124.1 , $ 103.4 and $ 65.4 in fiscal 2016 , 2015 and 2014 , respectively. Advertising — Advertising costs are expensed as incurred except for costs of producing media advertising such as television commercials or magazine advertisements, which are deferred until the first time the advertising takes place. The amounts reported as assets on the balance sheet were $1.6 and $1.4 as of September 30, 2016 and 2015 , respectively. Stock-based Compensation — The Company recognizes the cost of employee services received in exchange for awards of equity instruments based on the grant-date fair value of equity awards and the fair market value at each quarterly reporting date for liability awards. That cost is recognized over the period during which an employee is required to provide service in exchange for the award — the requisite service period (usually the vesting period). See Note 17 for disclosures related to stock-based compensation. Income Tax (Benefit) Provision — Income tax (benefit) provision is estimated based on income taxes in each jurisdiction and includes the effects of both current tax exposures and the temporary differences resulting from differing treatment of items for tax and financial reporting purposes. These temporary differences result in deferred tax assets and liabilities. A valuation allowance is established against the related deferred tax assets to the extent that it is not more likely than not that the future benefits will be realized. Reserves are recorded for estimated exposures associated with the Company’s tax filing positions, which are subject to periodic audits by governmental taxing authorities. Interest due to an underpayment of income taxes is classified as income taxes. The Company considers the undistributed earnings of its foreign subsidiaries to be permanently reinvested, so no U.S. taxes have been provided in relation to the Company's investment in its foreign subsidiaries. See Note 7 for disclosures related to income taxes.

Recently Issued Accounting Standards [Abstract]
Recently Issued and Adopted Accounting Standards	The Company has considered all new accounting pronouncements, and has concluded there are no new pronouncements (other than the ones described below) that will have a material impact on the results of operations, financial condition or cash flows based on current information. Recently Issued In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09, “Compensation - Stock Compensation (Topic 718): Improvement to Employee Share-Based Payment Accounting.” The updated guidance changes the accounting for certain aspects of share-based payment awards to employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification of certain items in the statement of cash flows. This ASU is effective for annual periods beginning after December 15, 2016, and interim periods therein (i.e., Post’s financial statements for the year ending September 30, 2018) with early adoption permitted. The Company is currently evaluating the impact of adopting this guidance. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross Versus Net),” which is intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” which clarifies the identification of performance obligations and the licensing implementation guidance. In May 2016, the FASB issued ASU 2016-11, “Revenue Recognition (Topic 605) and Derivatives and Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 Emerging Issues Task Force (“EITF”) Meeting,” which rescinds certain SEC Staff Observer comments from Accounting Standards Codification (“ASC”) Topic 605 “Revenue Recognition.” These rescissions include changes to topics pertaining to accounting for shipping and handling fees and costs and accounting for consideration given by a vendor to a customer. In May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients,” which provides clarifying guidance in certain narrow areas and adds some practical expedients. The effective dates for these ASUs are the same as the effective date for ASU 2014-09 (i.e., Post’s financial statements for the year ending September 30, 2019). The Company is currently evaluating its existing revenue recognition policies to determine the types of contracts that are within the scope of this guidance and the impact the adoption of this standard may have on the consolidated financial statements. It has not yet been determined if the full retrospective or the modified retrospective method will be applied. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” This standards update requires a company to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for lessees, lessors and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. This ASU is effective for annual periods beginning after December 15, 2018, and interim periods therein (i.e., Post’s financial statements for the year ending September 30, 2020), with early adoption permitted. At adoption, this update will be applied using a modified retrospective approach. The Company is currently evaluating the impact and timing of adopting this guidance, however, an increase in both assets and liabilities is expected. Recently Adopted In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments,” which provides guidance on the following cash flow issues: debt prepayment or extinguishment costs, settlement of zero-coupon debt or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions and separately identifiable cash flows and application of the predominance principle. The Company early adopted this ASU using a retrospective approach, as permitted by the standard, at September 30, 2016, and all applicable changes have been made to the Consolidated Statements of Cash Flows. The adoption of this ASU had no impact on the Consolidated Statements of Cash Flows for the years ended September 30, 2015 and 2014. In November 2015, the FASB issued ASU 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” This standards update requires an entity to classify all deferred tax assets and liabilities as non-current. ASU 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, with early adoption permitted and can be applied either retrospectively or prospectively. The Company prospectively adopted this ASU at December 31, 2015 and is now presenting all deferred tax assets and liabilities as non-current on the Condensed Balance Sheets. Balances at September 30, 2015 were not retrospectively adjusted as the Company chose to prospectively adopt this ASU. In April 2015, the FASB issued ASU 2015-03 “Simplifying the Presentation of Debt Issuance Costs,” which changes the presentation of debt issuance costs in financial statements. The standards update requires an entity to present debt issuance costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. In August 2015, the FASB issued ASU 2015-15 “Presentation and Subsequent Measurement of Debt issuance Costs Associated with Line-of-Credit,” which indicates the Securities and Exchange Commission (“SEC”) staff would not object to an entity deferring and presenting debt issuance costs related to line-of-credit arrangements as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The Company early adopted this ASU using a retrospective approach at September 30, 2016, as permitted by the standard. The adoption resulted in the reclassification of $53.5 and $56.5 in debt issuance costs, net of accumulated amortization, from “Prepaid expenses and other current assets” and “Other assets” to “Long-term debt” on the Consolidated Balance Sheets at September 30, 2016 and 2015, respectively. The reclassifications excluded amounts related to the Company’s credit agreement, in accordance with the standard.

WEF is a producer, processor and wholesale distributor of eggs and egg products and is reported in the Michael Foods Group segment (see Note 20). Based upon the purchase price allocation, the Company recorded $12.7 of customer relationships to be amortized over a weighted-average period of 20 years and $2.5 to trademarks and brands to be amortized over a weighted-average period of 20 years. Net sales and operating profit included in the Consolidated Statements of Operations related to WEF were $88.3 and $14.6 , respectively, for the year ended September 30, 2016 .

The purchase price was allocated to acquired assets and assumed liabilities based on their estimated fair values at the date of acquisition, and any excess was allocated to goodwill, as shown in the table below. Goodwill represents the value the Company expects to achieve through the implementation of operational synergies and the expansion of the business into new or growing segments of the industry. The Company expects the final fair value of goodwill related to the acquisition of WEF to be deductible for U.S. income tax purposes. The following table provides the allocation of the purchase price related to the fiscal 2016 acquisition of WEF based upon the fair value of assets and liabilities assumed. WEF Cash and cash equivalents $ 19.2 Receivables 11.1 Inventories 10.3 Prepaid expenses and other current assets 0.5 Property 56.2 Goodwill 4.2 Other intangible assets 15.2 Other assets 0.1 Accounts payable (2.2 ) Other current liabilities (1.0 ) Total acquisition cost $ 113.6 Divestitures In March 2016, the Company sold certain assets of its Michael Foods Canadian egg business, included in the Michael Foods Group segment (see Note 20), to a third party for $6.9 , subject to working capital and other adjustments, resulting in net cash received of $6.4 .

The respective purchase prices were allocated to acquired assets and liabilities based on their estimated fair values at the date of acquisition, and any excess was allocated to goodwill, as shown in the following table and discussed above. Goodwill represents the value the Company expects to achieve through the implementation of operational synergies and the expansion of the business into new growing segments of the industry.

The Company estimates approximately $104.4 of tax deductible goodwill and intangible assets will result from the Dymatize acquisition. The Company expects the fair value of goodwill generated by the cereal brand acquisition to be fully tax deductible.

Post Consumer Brands Michael Foods Group Active Nutrition Private Brands Total Balance, September 30, 2014 Goodwill (gross) $ 1,799.3 $ 1,347.2 $ 151.3 $ 229.3 $ 3,527.1 Accumulated impairment losses (609.1 ) — (31.3 ) — (640.4 ) Goodwill (net) $ 1,190.2 $ 1,347.2 $ 120.0 $ 229.3 $ 2,886.7 Goodwill acquired 195.6 — 18.6 49.6 263.8 Impairment loss — — (57.0 ) — (57.0 ) Purchase price true-up adjustment — (5.6 ) 10.8 — 5.2 Currency translation adjustment (1.0 ) — — (24.9 ) (25.9 ) Balance, September 30, 2015 Goodwill (gross) $ 1,993.9 $ 1,341.6 $ 180.7 $ 254.0 $ 3,770.2 Accumulated impairment losses (609.1 ) — (88.3 ) — (697.4 ) Goodwill (net) $ 1,384.8 $ 1,341.6 $ 92.4 $ 254.0 $ 3,072.8 Goodwill acquired — 4.2 — — 4.2 Currency translation adjustment 0.1 — — 2.6 2.7 Balance, September 30, 2016 Goodwill (gross) $ 1,994.0 $ 1,345.8 $ 180.7 $ 256.6 $ 3,777.1 Accumulated impairment losses (609.1 ) — (88.3 ) — (697.4 ) Goodwill (net) $ 1,384.9 $ 1,345.8 $ 92.4 $ 256.6 $ 3,079.7 Goodwill represents the excess of the cost of acquired businesses over the fair market value of their identifiable net assets. The Company conducts a goodwill impairment qualitative assessment during the fourth quarter of each fiscal year following the annual forecasting process, or more frequently if facts and circumstances indicate that goodwill may be impaired. The goodwill impairment qualitative assessment requires an assessment to determine if it is more likely than not that the fair value of the business is less than its carrying amount. If adverse qualitative trends are identified that could negatively impact the fair value of the business, a quantitative goodwill impairment test is performed. In fiscal years 2016 , 2015 and 2014 , the Company elected not to perform a qualitative assessment and instead performed a quantitative impairment test for all reporting units. The estimated fair value is determined using a combined income and market approach with a greater weighting on the income approach. The income approach is based on discounted future cash flows and requires significant assumptions, including estimates regarding future revenue, profitability, and capital requirements. The market approach is based on a market multiple (revenue and EBITDA which stands for earnings before interest, income taxes, depreciation, and amortization) and requires an estimate of appropriate multiples based on market data. For the year ended September 30, 2016, the Company concluded that there was no impairment of goodwill as of September 30, 2016. With the exception of Dymatize, all reporting units passed the first step of the impairment test. Dymatize failed step one and accordingly, step two of the analysis was performed. Based on the results of step two, it was determined that the fair value of the goodwill allocated to the Dymatize reporting unit exceeded its carrying value by approximately $36.0 and was therefore not impaired as of September 30, 2016. At September 30, 2016, the estimated fair values of all other reporting units exceed their carrying values by at least 33% . As of September 30, 2015, the Company recorded a charge of $57.0 for the impairment of goodwill. The impairment charge related to the Active Nutrition segment and was primarily the result of fourth quarter production issues at Dymatize which resulted in the Company’s decision to close its manufacturing facility and permanently transfer production to third party facilities under co-manufacturing agreements. As of September 30, 2014, the Company recorded a total charge of $212.6 for the impairment of goodwill. The Post Consumer Brands segment recognized $181.3 primarily resulting from the acceleration of declines within the branded RTE cereal category. Additionally, the expectation was that revenue and profit growth would be challenged in the medium to long-term. The Active Nutrition segment recognized charges of $31.3 resulting from reduced near-term profitability related to supply chain disruptions at Dymatize, which were identified subsequent to the initial valuation at the acquisition date of February 1, 2014, and incremental remediation expenses. These fair value measurements fell within Level 3 of the fair value hierarchy as described in Note 13. The goodwill impairment losses are aggregated with trademark impairment losses in “Impairment of goodwill and other intangible assets” in the Consolidated Statements of Operations.

A reconciliation of income tax benefit with amounts computed at the statutory federal rate follows: Year Ended September 30, 2016 2015 2014 Computed tax at federal statutory rate (35%) $ (10.5 ) $ (58.6 ) $ (149.4 ) Non-deductible goodwill impairment loss — 16.5 70.9 Non-deductible compensation 2.6 0.4 0.8 Non-deductible transaction costs — 0.6 2.8 Domestic production activities deduction (4.3 ) (5.9 ) — State income taxes, net of effect on federal tax (6.2 ) (7.2 ) (6.6 ) Non-taxable interest income (2.6 ) (2.7 ) (2.9 ) Valuation allowances 3.8 6.7 2.3 Change in deferred tax rates (2.0 ) 4.9 (0.9 ) Uncertain tax positions (2.0 ) (3.4 ) (0.2 ) Sale and liquidation of Michael Foods Canadian egg business (3.6 ) — — Enacted tax law and changes 0.7 (0.4 ) — Income tax credits (1.5 ) (0.4 ) (0.1 ) Rate differential on foreign income (1.8 ) (1.4 ) (0.1 ) Other, net (none in excess of 5% of statutory tax) 0.6 (1.1 ) (0.3 ) Income tax benefit $ (26.8 ) $ (52.0 ) $ (83.7 ) Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

As of September 30, 2016, Post had no NOL carryforwards in foreign jurisdictions. Certain of these NOLs and carryforwards were acquired through acquisitions made during fiscal 2013 and 2014. As a result of these ownership changes, the deductibility of the NOLs is subject to limitation under section 382 of the Internal Revenue Code and similar limitations under state tax law. Giving consideration to the section 382 and state limitations, the Company believes it will generate sufficient taxable income to fully utilize the federal and certain state NOLs before they expire. Approximately $7.8 of the deferred tax asset related to the state NOLs has been offset by a valuation allowance based on management’s judgment that it is more likely than not that the benefits of those deferred tax assets will not be realized in the future. No provision has been made for income taxes on undistributed earnings of consolidated non-U.S. subsidiaries of $18.9 at September 30, 2016 since it is our intention to indefinitely reinvest undistributed earnings of our foreign subsidiaries. It is not practicable to estimate the additional income taxes and applicable foreign withholding taxes that would be payable on the remittance of such undistributed earnings. For fiscal 2016 , 2015 and 2014 , foreign income before income taxes was $29.6 , $7.0 and $0.6 , respectively. Unrecognized Tax Benefits The Company recognizes the tax benefit from uncertain tax positions only if it is “more likely than not” the tax position will be sustained on examination by the taxing authorities. The tax benefits recognized from such positions are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. To the extent the Company’s assessment of such tax positions changes, the change in estimate will be recorded in the period in which the determination is made. Unrecognized tax benefits activity for the years ended September 30, 2016 and 2015 is presented in the following table: Unrecognized tax benefits, September 30, 2014 $ 7.4 Additions for tax positions taken in current year and acquisitions 7.2 Reductions for tax positions taken in prior years (2.8 ) Settlements with tax authorities/statute expirations (0.5 ) Unrecognized tax benefits, September 30, 2015 $ 11.3 Additions for tax positions taken in current year and acquisitions 0.1 Reductions for tax positions taken in prior years (1.6 ) Settlements with tax authorities/statute expirations (0.5 ) Unrecognized tax benefits, September 30, 2016 $ 9.3 The amount of the net unrecognized tax benefits that, if recognized, would directly affect the effective tax rate is $6.0 at September 30, 2016 . The Company believes that, due to expiring statutes of limitations and settlements with authorities, it is reasonably possible that the total unrecognized tax benefits may decrease by approximately $0.7 within twelve months of the reporting date. The Company classifies tax-related interest and penalties as components of income tax expense. The accrued interest and penalties are not included in the table above. The Company had accrued interest and penalties of approximately $2.4 and $2.5 at September 30, 2016 and September 30, 2015 , respectively. The Company had net expense of approximately $(0.1) , $0.0 and $0.8 for interest and penalties in the Consolidated Statements of Operations for the years ended September 30, 2016 , 2015 and 2014 , respectively. Interest and penalties were computed on the difference between the tax position recognized for financial reporting purposes and the amount previously taken on the Company’s tax returns. U.S. federal, U.S. state and Canadian income tax returns for the tax years ended September 30, 2015 , 2014 and 2013 are subject to examination by the tax authorities in each respective jurisdiction. The Michael Foods tax return for the short year ended June 2, 2014 was examined by the Internal Revenue Service without adjustment. For the acquisitions made in 2015 and 2014 , the seller generally retained responsibility for all income tax liabilities through the date of acquisition. With respect to the Michael Foods acquisition, the Company assumed all income tax liabilities for those jurisdictions which remain subject to examination, consisting of tax years 2012 through the short year ended June 2, 2014, the date of acquisition. The Company did not assume any pre-acquisition tax liabilities related to the 2016 acquisition of WEF.

Earnings Per Share [Abstract]
Earnings Per Share	Basic loss per share is based on the average number of common shares outstanding during the period. Diluted loss per share is based on the average number of shares used for the basic per share calculation, adjusted for the dilutive effect of stock options, stock appreciation rights and restricted stock units using the “treasury stock” method. The impact of potentially dilutive convertible preferred stock is calculated using the “if-converted” method. The Company’s tangible equity units (“TEUs”) (see Note 18) are assumed to be settled at the minimum settlement amount for weighted-average shares for basic loss per share. For diluted loss per share, the shares, to the extent dilutive, are assumed to be settled as described in Note 18. Year ended September 30, 2016 2015 2014 Net loss for basic loss per share $ (28.4 ) $ (132.3 ) $ (358.6 ) Net loss for diluted loss per share $ (28.4 ) $ (132.3 ) $ (358.6 ) Weighted-average shares outstanding 63.9 51.8 38.0 Effect of TEUs on weighted-average shares for basic loss per share 4.9 4.9 1.7 Weighted-average shares for basic loss per share 68.8 56.7 39.7 Total dilutive securities — — — Weighted-average shares for diluted loss per share 68.8 56.7 39.7 Basic loss per common share $ (0.41 ) $ (2.33 ) $ (9.03 ) Diluted loss per common share $ (0.41 ) $ (2.33 ) $ (9.03 ) The following table details the securities that have been excluded from the calculation of weighted-average shares for diluted loss per share as they were anti-dilutive.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments and Hedging	In the ordinary course of business, the Company is exposed to commodity price risks relating to the acquisition of raw materials and supplies, interest rate risks relating to floating rate debt, and foreign currency exchange rate risks relating to its foreign subsidiaries. The Company utilizes derivative financial instruments, including (but not limited to) futures contracts, option contracts, forward contracts and swaps, to manage certain of these exposures by hedging when it is practical to do so. The Company does not hold or issue financial instruments for speculative or trading purposes. The Company maintains options, futures contracts and interest rate swaps which have been designated as economic hedges of raw materials, energy purchases and variable rate debt. As of September 30, 2016 , the notional amounts of commodity contracts and energy futures were $49.8 and $23.6 , respectively. These contracts relate to raw materials that generally will be utilized within the next 12 months. At September 30, 2016 and September 30, 2015 , the Company had pledged collateral of $6.1 and $10.7 , respectively, related to its commodity and energy hedging contracts. These amounts are classified as “Restricted cash” on the Consolidated Balance Sheets. As of September 30, 2016 , the Company had interest rate swaps with a notional amount of $77.6 that obligate Post to pay a fixed rate of 3.1% and receive one-month LIBOR, and require monthly settlements. These settlements began in July 2016 and end in May 2021. In addition, the Company has interest rate swaps with a $750.0 notional amount that obligate Post to pay a weighted-average fixed interest rate of approximately 4.0% and receive three-month LIBOR and will result in a net lump sum settlement in July 2018, as well as interest rate swaps with a $899.3 notional amount that obligate Post to pay a weighted-average fixed interest rate of approximately 3.7% and receive three-month LIBOR and will result in a net lump sum settlement in December 2019. Commodity and energy derivatives are valued using an income approach based on index prices less the contract rate multiplied by the notional amount. The Company’s calculation of the fair value of interest rate swaps is derived from a discounted cash flow analysis based on the terms of the contract and the relevant interest rate curve. The following tables present the balance sheet location and fair value of the Company’s derivative instruments on a gross and net basis as of September 30, 2016 and 2015 . The Company does not offset derivative assets and liabilities within the Consolidated Balance Sheets.

This investment is in the same funds and purchased in substantially the same amounts as the participants’ selected investment options (excluding Post common stock equivalents), which represent the underlying liabilities to participants in the Company’s deferred compensation plans. Deferred compensation liabilities are recorded at amounts due to participants in cash, based on the fair value of participants’ selected investment options (excluding certain Post common stock equivalents to be distributed in shares) using the market approach. The Company utilizes the income approach to measure fair value for its derivative assets, which include commodity options and futures contracts. The income approach uses pricing models that rely on market observable inputs such as yield curves and forward prices. Refer to Note 12 for the classification of changes in fair value of derivative assets and liabilities measured at fair value on a recurring basis within the Consolidated Statements of Operations. As stated previously (see Note 4), the Company had land, building and equipment classified as assets held for sale related to the closure of its Modesto, California facility, and land and building classified as assets held for sale related to the closure of its Farmers Branch, Texas facility as of September 30, 2016 . At September 30, 2015 , the Company had land, building and equipment classified as assets held for sale related to the closure of its Modesto, California facility as well as machinery and equipment classified as assets held for sale related to the closure of its Farmers Branch, Texas facility. At September 30, 2016 and September 30, 2015 , the carrying value and estimated fair value less estimated costs to sell of the assets held for sale was $10.1 and $11.4 , respectively, and is included in “Prepaid expenses and other current assets” on the Consolidated Balance Sheets. The fair value of the assets held for sale were measured at fair value on a nonrecurring basis based on third-party offers to purchase the assets. The fair value measurement was categorized as Level 3, as the fair values utilize significant unobservable inputs. The following table summarizes the Level 3 activity. Balance, September 30, 2014 $ 16.4 Transfers into held for sale 46.2 Losses on assets held for sale (34.2 ) Proceeds from the sale of assets held for sale (24.0 ) Gain on sale of plant 7.0 Balance, September 30, 2015 $ 11.4 Transfers into held for sale 9.6 Losses on assets held for sale (9.3 ) Proceeds from the sale of assets held for sale (1.6 ) Balance, September 30, 2016 $ 10.1 The carrying amounts reported on the Consolidated Balance Sheets for cash and cash equivalents, receivables and accounts payable approximate fair value because of the short maturities (less than 12 months) of these financial instruments.

The outstanding amounts under the Revolving Credit Facility must be repaid on or before January 29, 2019. The Company incurred $3.6 of issuance costs in connection with the Credit Agreement. The revolving credit facility has outstanding letters of credit of $11.8 which reduces the available borrowing capacity to $388.2 at September 30, 2016 . Borrowings under the Revolving Credit Facility bear interest at the Eurodollar Rate or the Base Rate (as such terms are defined in the Credit Agreement) plus an applicable margin ranging from 2.00% to 2.50% for Eurodollar Rate-based loans and from 1.00% to 1.50% for Base Rate-based loans, depending upon the Company’s senior secured leverage ratio. On June 2, 2014, the Company entered into a Joinder Agreement No. 2 (the “Joinder No. 2”), by and among Barclays Bank PLC, the Company and the guarantors party thereto, and consented to by Wells Fargo Bank, National Association, as Administrative Agent. The Joinder No. 2 provided for, upon completion of the acquisition of Michael Foods and subject to certain other conditions, an incremental term loan of $885.0 (the “Prior Term Loan”) under the Company’s existing Credit Agreement. Pursuant to the Joinder No. 2, the Company borrowed approximately $885.0 as a Term Loan under the Credit Agreement. The loan was issued at 99.5% of par and the Company received $860.9 after accounting for the original issue discount of $4.4 and paying investment banking and other fees of $19.7 . On March 6, 2015, the Company entered into a Second Amendment to the Credit Agreement. On May 4, 2015, Post entered into a Joinder Agreement No. 3 (the “Joinder No. 3”), by and among Credit Suisse AG, Cayman Islands Branch, the Company and the guarantors party thereto, and consented to by Wells Fargo Bank, National Association, as Administrative Agent. The Joinder No. 3 provided for, in connection with the completion of the Company’s acquisition of MOM Brands, an incremental term loan of $700.0 (the “New Term Loan”) under the Company’s Credit Agreement. The Company incurred $19.4 of issuance costs in connection with the Credit Agreement and the New Term Loan as of September 30, 2015. The outstanding amounts under the New Term Loan bear interest at the same rate as the outstanding amounts under the Prior Term Loan. On May 4, 2015, Wells Fargo Bank, National Association resigned as Administrative Agent under the Credit Agreement and was replaced by Barclays Bank PLC. The Company utilized a portion of the net proceeds from the fiscal 2015 issuance of the 7.75% senior notes and the 8.00% senior notes, together with the net proceeds from the August 18, 2015 common stock issuance to repay $1,200.0 of the Prior Term Loan and the New Term Loan outstanding under the Credit Agreement. In fiscal 2016, the Company utilized a portion of the net proceeds from the issuance of the 5.00% senior notes to repay the remaining $374.4 balance of the term loan. In connection with the early repayment of the term loan, the Company expensed $7.8 and $30.0 of deferred financing fees and unamortized debt discount in the years ended September 30, 2016 and 2015, respectively, which is reported as “Loss on extinguishment of debt” in the Consolidated Statement of Operations. The Credit Agreement contains customary affirmative and negative covenants for agreements of this type, including delivery of financial and other information, compliance with laws, maintenance of property, existence, insurance and books and records, inspection rights, obligation to provide collateral and guarantees by new subsidiaries, limitations with respect to indebtedness, liens, fundamental changes, restrictive agreements, use of proceeds, amendments of organization documents, accounting changes, prepayments and amendments of indebtedness, dispositions of assets, acquisitions and other investments, transactions with affiliates, dividends and redemptions or repurchases of stock, capital expenditures, and granting liens on certain real property. The Credit Agreement also contains customary financial covenants including: (a) a quarterly maximum senior secured leverage ratio of 3.00 to 1.00, and (b) a quarterly minimum interest coverage ratio of 1.75 to 1.00. With limited exceptions, the Credit Agreement permits the Company to incur additional unsecured debt only if its consolidated interest coverage ratio, calculated as provided in the Credit Agreement, would be greater than 2.00 to 1.00 after giving effect to such new debt. The Credit Agreement provides for customary events of default, including material breach of representations and warranties, failure to make required payments, failure to comply with certain agreements or covenants, failure to pay, or default under, certain other material indebtedness, certain events of bankruptcy and insolvency, inability to pay debts, the occurrence of one or more unstayed or undischarged judgments in excess of $75.0 , or attachments issued against a material part of the Company’s property, change in control, the invalidity of any loan document, the failure of the collateral documents to create a valid and perfected first priority lien and certain ERISA events. Upon the occurrence of an event of default, the maturity of the loans under the Credit Agreement may be accelerated and the agent and lenders under the Credit Agreement may exercise other rights and remedies available at law or under the loan documents, including with respect to the collateral and guarantees for the Company’s obligations under the Credit Agreement. The Company’s obligations under the Credit Agreement are unconditionally guaranteed by each of its existing and subsequently acquired or organized material domestic subsidiaries. The Company’s obligations under the Credit Agreement are secured by security interests on substantially all of the personal property assets of the Company and the Guarantors and are secured by the material domestic real property assets of the Company and the Guarantors. In February 2014, the Company paid $2.5 of financing fees to the underwriters of a financing commitment the Company entered into in September 2013 to fund our acquisition of Dakota Growers. The commitment was not exercised and the Company recorded the full amount to “Interest expense, net” in the Consolidated Statement of Operations during the year ended September 30, 2014. In addition, financing costs of $4.3 related to the unused bridge loan and $6.7 for the portion of the term loan commitment not used were immediately recorded to “Interest expense, net” in the Consolidated Statement of Operations during the year ended September 30, 2014. In connection with the acquisition of Michael Foods, the Company assumed a 4.57% 2012 Series Bond that guarantees the repayment of certain industrial revenue bonds used for the expansion of the wastewater treatment facility in Wakefield, Nebraska. The bond bears interest at a rate of 4.57% and matures September 15, 2017. Debt Covenants The terms of the Credit Facility require the Company to comply with certain financial covenants consisting of ratios for maximum senior secured leverage and minimum interest expense coverage. As of September 30, 2016 , the Company was in compliance with all such financial covenants. The Company does not believe non-compliance is reasonably likely in the foreseeable future.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Legal Proceedings Antitrust claims: In late 2008 and early 2009, some 22 class-action lawsuits were filed in various federal courts against Michael Foods, Inc. and approximately 20 other defendants (producers of shell eggs and egg products, and egg industry organizations), alleging violations of federal and state antitrust laws in connection with the production and sale of shell eggs and egg products, and seeking unspecified damages. Michael Foods has denied liability. In December 2008, the Judicial Panel on Multidistrict Litigation ordered the transfer of all cases to the Eastern District of Pennsylvania for coordinated and/or consolidated pretrial proceedings. Between late 2010 and early 2012, a number of companies (primarily large grocery chains and food companies that purchase considerable quantities of eggs) opted out of any eventual class of direct purchaser plaintiffs and brought their own separate actions against the defendants. These “opt-out” plaintiffs assert essentially the same allegations as plaintiffs in the main direct purchaser action. The opt-out cases also are pending in the Eastern District of Pennsylvania, where they are being treated as related to the main action. Additionally, all or most defendants, including Michael Foods, received a Civil Investigative Demand (“CID”) issued by the Florida Attorney General in late 2008, regarding an investigation of possible anticompetitive activities “relating to the production and sale of eggs or egg products.” The CID requested information related to the pricing and supply of shell eggs and egg products, and participation in various programs of United Egg Producers. The Florida Attorney General’s Office has not taken any further enforcement action during the pendency of the civil antitrust litigation referenced above. Motions related to class certification: On September 18, 2015, the court denied the motion of the indirect purchaser plaintiffs (primarily consumers who purchased shell eggs from grocery stores) for class certification. The indirect purchaser plaintiffs have filed an alternative motion for certification of an injunction class, and the denial of their original motion is subject to appeal. On September 21, 2015, the court granted the motion of the direct purchaser plaintiffs to certify a shell-egg subclass, but denied their motion to certify an egg-products subclass. However, on September 2, 2016, the defendants filed a motion to decertify the class of direct purchasers of shell eggs; there has been no ruling on that motion. Motions for summary judgment : On September 6, 2016, the court granted the defendants’ motion to dismiss claims based on purchases of egg products, thereby limiting the claims to shell eggs. Certain of the egg products purchasers whose claims were dismissed have appealed to the Third Circuit Court of Appeals. On September 28, 2016, the court denied individual motions for summary judgment made by Michael Foods and three other defendants that had sought the dismissal of all claims against them. Michael Foods has moved to have denial of its motion for summary judgment certified for immediate appeal to the Third Circuit Court of Appeals; there has been no ruling on that motion. In light of the denial of Michael Foods’ motion for summary judgment, the Company will continue to vigorously defend the cases. Past settlements with the direct purchaser class in this case by other defendants have been as high as $28.0 . Amounts paid in settlements with the opt-out plaintiffs are not known. There can be no assurance that the cases against Michael Foods will be resolved by settlements, or that any settlements would be in line with the previous settlements referenced. Under current law, any settlement paid, if any, would be deductible for federal income tax purposes. The Company has accrued $28.5 for these matters. We record reserves for litigation losses in accordance with ASC Topic 450, “Contingencies” (“ASC 450”). Under ASC 450, a loss contingency is recorded if a loss is probable and can be reasonably estimated. We record probable loss contingencies based on the best estimate of the loss. If a range of loss can be reasonably estimated, but no single amount within the range appears to be a better estimate than any other amount within the range, the minimum amount in the range is accrued. These estimates are often initially developed earlier than when the ultimate loss is known, and the estimates are adjusted if additional information becomes known. While the Company believes its accruals for this matter are appropriate, the final amounts required to resolve such matters could differ materially from recorded estimates and the Company's results of operations and cash flows could be materially affected. Accordingly, the Company cannot predict what impact, if any, these matters and any results from such matters could have on the future results of operations. Other: The Company is subject to various other legal proceedings and actions arising in the normal course of business. In the opinion of management, based upon the information presently known, the ultimate liability, if any, arising from such pending legal proceedings, as well as from asserted legal claims and known potential legal claims which are likely to be asserted, taking into account established accruals for estimated liabilities (if any), are not expected to be material individually or in the aggregate to the consolidated financial position, results of operations or cash flows. In addition, while it is difficult to estimate the potential financial impact of actions regarding expenditures for compliance with regulatory matters, in the opinion of management, based upon the information currently available, the ultimate liability arising from such compliance matters is not expected to be material to the consolidated financial position, results of operations or cash flows. Post’s operations also are subject to various federal, state and local laws and regulations with respect to environmental matters, including air quality, wastewater discharge and pretreatment, storm water, waste handling and disposal, and other regulations intended to protect public health and the environment. In the United States, the laws and regulations include the Clean Air Act, the Clean Water Act and the Resource Conservation and Recovery Act. The Company’s foreign facilities are subject to local and national regulations similar to those applicable to us in the United States. Additionally, many of the Michael Foods facilities discharge wastewater pursuant to wastewater discharge permits. The Company disposes of waste from its internal egg production primarily by transferring it to farmers for use as fertilizer and disposes of solid waste from potato processing primarily by transferring it to one or more processors who convert it to animal feed. Post has made, and will continue to make, expenditures to ensure environmental compliance. Lease Commitments Future minimum rental payments under noncancelable operating leases in effect as of September 30, 2016 were $16.7 , $16.2 , $15.2 , $12.7 , $11.6 and $25.9 for fiscal 2017 , 2018 , 2019 , 2020 , 2021 and thereafter, respectively.

Pension and Other Postretirement Benefit Expense [Abstract]
Pension and Other Postretirement Benefits	The Company maintains qualified defined benefit plans in the United States and Canada for certain employees primarily within its Post Consumer Brands segment. Certain of the Company’s employees are eligible to participate in the Company’s qualified and supplemental noncontributory defined benefit pension plans and other postretirement benefit plans (partially subsidized retiree health and life insurance) or separate plans for Post Foods Canada Inc. The following disclosures reflect amounts related to the Company’s employees based on separate actuarial valuations, projections and certain allocations. Amounts for the Canadian plans are included in these disclosures and are not disclosed separately because they do not constitute a significant portion of the combined amounts. Effective January 1, 2011, benefit accruals for defined benefit pension plans were frozen for all administrative employees and certain production employees. The following table provides a reconciliation of the changes in the plans’ benefit obligations and fair value of assets over the two year period ended September 30, 2016 , and a statement of the funded status and amounts recognized in the combined balance sheets as of September 30 of both years.

The accumulated benefit obligation exceeded the fair value of plan assets for the domestic pension plans at September 30, 2016 and September 30, 2015 . The aggregate accumulated benefit obligation for pension plans was $68.6 at September 30, 2016 and $55.1 at September 30, 2015 . The following tables provide the components of net periodic benefit cost for the plans and amounts recognized in other comprehensive income.

The discount rate was 4.6% for the first five months of benefit cost and 4.22% for the last seven months of benefit cost. The estimated net actuarial loss and prior service cost (credit) expected to be reclassified from accumulated other comprehensive loss into net periodic benefit cost during 2017 related to pension benefits are $1.6 and $0.2 , respectively. The corresponding amounts related to other postretirement benefits are $0.7 and $(4.8) , respectively. The expected return on pension plan assets was determined based on historical and expected future returns of the various asset classes, using the target allocation. The broad target allocations are 50.0% equity securities (comprised of 27.5% U.S. equities and 22.5% foreign equities), 39.5% debt securities, 10.0% real assets and 0.5% cash. At September 30, 2016 , equity securities were 49.8% , debt securities were 42.4% , real assets were 6.6% and other was 1.2% of the fair value of total plan assets, approximately 81.0% of which was invested in passive index funds. At September 30, 2015 , equity securities were 48.6% , debt securities were 45.2% , real assets were 4.4% and other was 1.8% of the fair value of total plan assets, approximately 80.0% of which was invested in passive index funds. The allocation guidelines were established based on management’s determination of the appropriate risk posture and long-term objectives. The following table represents the pension plan’s assets measured at fair value on a recurring basis and the basis for that measurement. September 30, 2016 September 30, 2015 Total Level 1 Level 2 Total Level 1 Level 2 Mutual funds: Equities $ 27.0 $ — $ 27.0 $ 21.5 $ — $ 21.5 Bonds 6.0 6.0 — 4.8 4.8 — Pooled Assets 4.3 — 4.3 3.9 — 3.9 Fixed income 12.8 — 12.8 11.4 — 11.4 Real assets 3.6 — 3.6 2.0 — 2.0 53.7 6.0 47.7 43.6 4.8 38.8 Cash 0.6 0.6 — 0.8 0.8 — $ 54.3 $ 6.6 $ 47.7 $ 44.4 $ 5.6 $ 38.8 The fair value of mutual funds is based on quoted net asset values of the shares held by the plan at year end. For September 30, 2016 measurement purposes, the assumed annual rate of increase in the future per capita cost of covered health care benefits related to domestic plans for 2017 was 7.5% and 6.0% for participants under the age of 65 and over the age of 65, respectively, declining gradually to an ultimate rate of 5.0% for 2022 and beyond. For September 30, 2015 measurement purposes, the assumed annual rate of increase in the future per capita cost of covered health care benefits related to domestic plans for 2016 was 8.0% and 6.2% for participants under the age of 65 and over the age of 65, respectively, declining gradually to an ultimate rate of 5.0% for 2022 and beyond. For September 30, 2016 and 2015 measurement purposes, the assumed annual rate of increase in the future per capita cost of covered health care benefits related to Canadian plans for the following fiscal year was 7.0% and 7.5% , respectively, declining gradually to an ultimate rate of 4.5% for 2021 and beyond for the year ended September 30, 2016 and 5.0% for 2021 and beyond for the year ended September 30, 2015 . A 1% change in assumed health care cost trend rates would result in the following changes in the accumulated postretirement benefit obligation and in the total service and interest cost components for fiscal 2016 . Increase Decrease Effect on postretirement benefit obligation $ 7.6 $ (6.1 ) Effect on total service and interest cost 0.9 (0.7 ) As of September 30, 2016 , expected future benefit payments and related federal subsidy receipts (Medicare Part D) in the next ten fiscal years were as follows: 2017 2018 2019 2020 2021 2022- 2026 Pension benefits $ 2.3 $ 2.2 $ 2.2 $ 2.3 $ 2.6 $ 16.9 Other benefits 2.4 2.9 3.1 3.3 3.3 18.0 Subsidy receipts — — 0.1 0.1 0.1 0.9 In addition to the above expected benefit payments, the Company expects to make contributions of $6.0 to its defined benefit pension plans during fiscal 2017 . In addition to the defined benefit plans described above, the Company sponsors a defined contribution 401(k) plan under which it makes matching contributions. The Company expensed $ 15.6 , $ 11.7 and $ 7.1 for the fiscal years ended September 30, 2016 , 2015 and 2014 , respectively.

Stock-Based Compensation Plans

Stock-Based Compensation Plans	12 Months Ended
Stock-Based Compensation Plans	Sep. 30, 2016
Stock-Based Compensation [Abstract]
Stock-Based Compensation	On February 3, 2012, the Company established the 2012 Long-Term Incentive Plan (the “2012 Plan”) which permits the issuance of various stock-based compensation awards up to 6.5 million shares. On January 29, 2016, the Company established the 2016 Long-Term Incentive Plan (the “2016 Plan”) which permits issuance of various stock-based compensation awards up to 2.4 million shares. The 2012 and 2016 plans allow the issuance of stock options, stock appreciation rights, performance shares, restricted stock, restricted stock units or other awards. Awards issued under the plans have a maximum term of 10 years, provided, however, that the Compensation Committee of the Board of Directors may, in its discretion, grant awards with a longer term to participants who are located outside the United States. Total compensation cost for cash and non-cash stock-based compensation awards recognized in the fiscal years ended 2016 , 2015 and 2014 was $25.6 , $29.2 and $16.6 , respectively, and the related recognized deferred tax benefit for each of those periods was approximately $8.0 , $10.6 and $5.4 , respectively. As of September 30, 2016 , the total compensation cost related to nonvested awards not yet recognized was $39.3 , which is expected to be recognized over a weighted average period of 2.8 years. In connection with an employee retirement and reorganization initiatives during fiscal 2015, the Company accelerated the vesting of unvested equity awards for 25 and 4 employees in the fiscal years ended September 2016 and 2015, respectively. As a result of this acceleration, the Company recorded $2.2 and $8.0 of incremental cash and stock-based compensation expense in the fiscal years ended September 30, 2016 and 2015, respectively. No such expense was recorded in the year ended September 30, 2014. Stock Appreciation Rights Information about stock-settled stock appreciation rights (“SSAR”) is summarized in the following table. Upon exercise of each SSAR, the holder will receive the number of shares of Post common stock equal in value to the difference between the exercise price and the fair market value at the date of exercise, less all applicable taxes. The Company uses shares from the Plan to settle SSARs exercised. The total intrinsic value of SSARs exercised was $5.1 , $2.1 and $2.4 in the fiscal years ended September 30, 2016 , 2015 and 2014 , respectively. Stock-Settled Stock Appreciation Rights Weighted- Average Exercise Price Per Share Weighted- Average Remaining Contractual Term in Years Aggregate Intrinsic Value Outstanding at September 30, 2015 242,335 $ 34.76 Granted — — Exercised (89,504 ) 22.28 Forfeited — — Expired — — Outstanding at September 30, 2016 152,831 42.07 6.75 $ 5.4 Vested and expected to vest as of September 30, 2016 152,831 42.07 6.75 5.4 Exercisable at September 30, 2016 92,831 35.19 5.94 3.9 In 2015 and 2014 , the Company granted 40,000 and 30,000 SSARs, respectively, to its non-management members of the Board of Directors. Due to vesting provisions of these awards the Company determined that these awards had subjective acceleration rights such that the Company expensed the grant date fair value upon issuance and recognized $0.7 and $0.5 of related expense for the years ended September 30, 2015 and 2014 , respectively. The following table provides the weighted-average grant date fair value of SSARs granted calculated using the Black-Scholes valuation model, which uses assumptions of expected life (term), expected stock price volatility, risk-free interest rate, and expected dividends (collectively, the “Black-Scholes Model”). The expected term is estimated based on the award’s vesting period and contractual term, along with historical exercise behavior on similar awards.

The weighted average assumptions and grant date fair values for SSARs granted during fiscal years ended 2015 and 2014 are summarized in the table below.

Expected volatilities are based on historical volatility trends and other factors. The risk-free rate is the interpolated U.S. Treasury rate for a term equal to the expected term. The following table presents the assumptions used to remeasure the fair value of outstanding SARs at September 30, 2016 , 2015 and 2014 . 2016 2015 2014 Expected term 3.8 4.8 2.5 Expected stock price volatility 32.4% 29.7% 27.6% Risk-free interest rate 1.0% 1.3% 0.8% Expected dividends 0% 0% 0% Fair value (per right) $44.44 $29.10 $15.80 Stock Options Stock Options Weighted- Average Exercise Price Per Share Weighted- Average Remaining Contractual Term in Years Aggregate Intrinsic Value Outstanding at September 30, 2015 4,175,000 $ 40.40 Granted 280,500 60.50 Exercised (200,000 ) 31.25 Forfeited — — Expired — — Outstanding at September 30, 2016 4,255,500 42.15 6.93 $ 149.0 Vested and expected to vest as of September 30, 2016 4,255,500 42.15 6.93 149.0 Exercisable at September 30, 2016 2,624,998 37.33 6.27 104.6 The fair value of each stock option was estimated on the date of grant using the Black-Scholes Model. The Company uses the simplified method for estimating a stock option term as it does not have sufficient historical share options exercise experience upon which to estimate an expected term. The expected term is estimated based on the award’s vesting period and contractual term, along with historical exercise behavior on similar awards. Expected volatilities are based on historical volatility trends and other factors. The risk-free rate is the interpolated U.S. Treasury rate for a term equal to the expected term. The weighted average assumptions and fair values for stock options granted during the years ended September 30, 2016 , 2015 and 2014 are summarized in the table below. 2016 2015 2014 Expected term 6.5 5.3 5.2 Expected stock price volatility 29.1% 27.9% 26.1% Risk-free interest rate 1.9% 1.6% 1.5% Expected dividends 0% 0% 0% Fair value (per option) $20.22 $7.22 $10.65 The total intrinsic value of stock options exercised was $5.1 and $12.4 in the fiscal years ended September 30, 2016 and 2015 , respectively.

The total vest date fair value of restricted stock units that vested during fiscal 2016 , 2015 and 2014 was $32.0 , $9.3 and $6.3 , respectively. In 2016 , the Company granted 15,000 restricted stock units to its non-management members of the Board of Directors. Due to vesting provisions of these awards, the Company determined that 12,500 of these awards had subjective acceleration rights such that the Company expensed the grant date fair value upon issuance and recognized $0.7 of related expense for the year ended September 30, 2016 .

Cash used by the Company to settle restricted stock units was $5.9 , $3.4 and $1.8 for the years ended September 30, 2016 , 2015 and 2014 , respectively. Deferred Compensation Post provides a deferred compensation plan for directors and key employees through which eligible participants may elect to defer payment of all or a portion of their compensation or bonus until a later date based on the participant’s elections. Deferrals for employee participants may be made into Post common stock equivalents (Equity Option) or into a number of funds operated by The Vanguard Group Inc. with a variety of investment strategies and objectives (Vanguard Funds). Deferrals for director participants must be made into Post common stock equivalents to also receive a 33% matching contribution. Deferrals into the Equity Option are distributed in Post stock for employees and cash for directors, while deferrals into the Vanguard Funds are distributed in cash. There are no significant costs related to the deferred compensation plan. Post funds its deferred compensation liability (potential cash distributions) by investing in the Vanguard Funds in the same amounts as selected by the participating employees. Both realized and unrealized gains and losses on these investments are included in “Selling, general and administrative expenses” and offset the related change in the deferred compensation liability.

Tangible Equity Units [Abstract]
Tangible Equity Units	In May 2014, the Company completed a public offering of 2.875 million TEUs, each with a stated value of $100.00 . Each TEU is comprised of a prepaid stock purchase contract and a senior amortizing note due June 1, 2017. The prepaid common stock purchase contracts were recorded as additional paid-in capital, net of issuance costs, and the senior notes have been recorded as long-term debt. Issuance costs associated with the debt component were recorded as deferred financing costs within “Long-term debt” on the Consolidated Balance Sheets and are being amortized using the effective interest rate method over the term of the instrument to June 1, 2017. Post allocated the proceeds from the issuance of the TEUs to equity and debt based on the relative fair values of the respective components of each TEU. The proceeds received in the offering were $278.6 , which were net of financing fees of $8.9 . The aggregate values assigned upon issuance of each component of the TEUs were as follows (amounts in millions except price per TEU): Equity Component Debt Component TEUs Total Price per TEU $ 85.48 $ 14.52 $ 100.00 Gross proceeds $ 245.7 $ 41.8 $ 287.5 Issuance costs (7.6 ) (1.3 ) (8.9 ) Net proceeds $ 238.1 $ 40.5 $ 278.6 Balance sheet impact (at issuance) Long-term debt (deferred financing fees) $ — $ 1.3 $ 1.3 Current portion of long-term debt — 13.3 13.3 Long-term debt — 28.5 28.5 Additional paid-in capital 238.1 — 238.1 The senior amortizing note component of each TEU’s initial principal amount of $14.5219 , bears interest at 5.25% per annum and has a final installment payment date on June 1, 2017. The Company pays equal quarterly cash installments of $1.3125 per amortizing note on March 1, June 1, September 1 and December 1 of each year. Payments commenced on September 1, 2014. Each installment constitutes a payment of interest and a partial repayment of principal. Unless settled earlier at the holder’s or the Company’s option, each purchase contract will automatically settle on June 1, 2017 (subject to postponement in certain limited circumstances), and the Company will deliver not more than 2.0964 shares and not less than 1.7114 shares of its common stock per purchase contract, each subject to adjustment. For each purchase contract, the Company will deliver on the third business day immediately following the last trading day of the observation period a number of shares of its common stock determined as described below. The “observation period” will be the 20 consecutive trading day period beginning on, and including, the 22nd scheduled trading day immediately preceding June 1, 2017 (the “mandatory settlement date”). The number of shares of the Company’s common stock issuable upon mandatory settlement of each purchase contract (the “settlement amount”) will be equal to the sum of the “daily settlement amounts” (as defined below) for each of the 20 consecutive trading days during the relevant observation period. The daily settlement amount for each purchase contract and for each of the 20 consecutive trading days during the observation period will consist of: • if the daily volume-weighted average price (“VWAP”) is equal to or greater than $58.4325 per share (the “threshold appreciation price”), subject to adjustment, a number of shares of the Company’s common stock equal to (i) 1.7114 shares of common stock, subject to adjustment (the “minimum settlement rate”) divided by (ii) 20; • if the daily VWAP is less than $58.4325 per share, subject to adjustment, but greater than $47.70 per share (the “reference price”), subject to adjustment, a number of shares of the Company’s common stock equal to (i) $100.00 divided by the daily VWAP (ii) divided by 20 ; and • if the daily VWAP of our common stock is less than or equal to $47.70 per share, subject to adjustment, a number of shares of the Company’s common stock equal to (i) 2.0964 shares of common stock, subject to adjustment (the “maximum settlement rate”), divided by (ii) 20. The initial minimum settlement rate is approximately equal to the TEU stated amount of $100.00 divided by the initial threshold appreciation price of $58.4325 per share. The initial maximum settlement rate is approximately equal to the TEU stated amount of $100.0 divided by the initial reference price of $47.70 per share. During the year ended September 30, 2016, holders settled 108,039 purchase contracts for which the Company issued 184,897 shares of common stock. No purchase contracts were settled and no shares of common stock were issued relating to the TEUs during the years ended September 30, 2015 and 2014.

Stockholders' Equity Attributable to Parent [Abstract]
Shareholders' Equity	The Company has two classes of preferred stock, the 3.75% Series B Cumulative Perpetual Convertible Preferred Stock (the “Series B Preferred”) and the 2.5% Series C Cumulative Perpetual Convertible Preferred Stock (the “Series C Preferred”). There are 50.0 preferred shares authorized. The Series B Preferred has a $0.01 par value per share and a $100.00 liquidation value per share. There were 1.5 and 2.4 shares outstanding at September 30, 2016 and 2015, respectively. The Series B Preferred earns cumulative dividends at a rate of 3.75% per annum payable quarterly on February 15, May 15, August 15 and November 15. The Series B Preferred is non-voting and ranks senior to the Company’s outstanding common stock upon the Company’s dissolution or liquidation. The Series B Preferred has no maturity date; however, holders of the Series B Preferred may convert their stock at an initial conversion rate of 2.1192 shares of the Company’s common stock per share of convertible preferred stock, which is equivalent to a conversion price of $47.19 per share of common stock. The Series C Preferred has a $0.01 par value per share and a $100.00 liquidation value per share. There were 3.2 and 3.2 shares outstanding at September 30, 2016 and 2015, respectively. The Series C Preferred earns cumulative dividends at a rate of 2.5% per annum payable quarterly on February 15, May 15, August 15 and November 15. The Series C Preferred is non-voting and ranks senior to the Company’s outstanding common stock upon the Company’s dissolution or liquidation. The Series C Preferred has no maturity date; however, holders of the Series C Preferred may convert their stock at an initial conversion rate of 1.8477 shares of the Company’s common stock per share of convertible preferred stock, which is equivalent to a conversion price of $54.12 per share of common stock. Fiscal 2016 In December 2015, the Company and a holder of the Company’s Series B Preferred entered into an exchange agreement pursuant to which the shareholder agreed to deliver 0.9 shares of the Series B Preferred to the Company in exchange for 2.0 shares of common stock and $10.9 of cash. The number of shares of common stock exchanged in the transaction was based upon the current conversion rate, under the Certificate of Designation, Rights and Preferences for the Series B Preferred, of 2.1192 shares of common stock per share of Series B Preferred. The cash paid of 10.9 was recorded as “Additional paid-in capital” on the Consolidated Balance Sheet. The Company may, from time to time, enter into common stock structured repurchase arrangements with financial institutions using general corporate funds. Under such arrangements, the Company pays a fixed sum of cash upon execution of each agreement in exchange for the right to receive either a pre-determined amount of cash or Post common stock. Upon expiration of each agreement, if the closing market price of Post’s common stock is above the pre-determined price, the Company will have the initial investment returned with a premium in cash. If the closing market price of Post’s common stock is at or below the pre-determined price, the Company will receive the number of shares specified in the agreement. In March 2016, the Company entered into a structured share repurchase arrangement which required cash payments totaling $28.3 , including transaction-related fees of $0.2 . At the May 2016 expiration of the agreement, the market price of Post’s common stock exceeded the pre-determined contract price, resulting in cash payments to the Company of $29.4 . Prepayments and cash receipts at settlement under the agreement were recorded as “Additional paid-in capital” on the Consolidated Balance Sheets. Fiscal 2015 In February 2015, the Company issued 7.48 million shares of common stock at a price to the public of $47.50 per share. The Company received net proceeds of $341.4 after paying offering related fees and expenses of approximately $13.7 . On May 4, 2015, the Company completed its acquisition of MOM Brands. The purchase price was partially funded by the issuance of 2.45 million shares of the Company’s common stock to the former owners of MOM Brands. The shares were valued at the May 1, 2015 closing price of $46.60 per share for a total issuance of $114.4 . The Company did not receive any of the proceeds from these shares of common stock. In August 2015, the Company issued 6.73 million shares of common stock at a price to the public of $60.00 per share. The Company received net proceeds of $391.3 after paying offering related fees and expenses of approximately $12.3 .

Schedule Of Condensed Financial Statements [Abstract]
Guarantor Financials	All of the Company’s senior notes (see Note 14) are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by each of our existing 100% owned domestic subsidiaries and future domestic subsidiaries, the “Guarantors.” Our foreign subsidiaries, the “Non-Guarantors,” do not guarantee the senior notes. These guarantees are subject to release in limited circumstances (only upon the occurrence of certain customary conditions). Set forth below are the condensed consolidating financial statements presenting the results of operations, financial position and cash flows of the Parent Company (Post Holdings, Inc.), the Guarantors on a combined basis, the Non-Guarantors on a combined basis and eliminations necessary to arrive at the information for the Company as reported, on a consolidated basis. The Condensed Consolidating Financial Statements present the Parent Company’s investments in subsidiaries using the equity method of accounting. Eliminations represent adjustments to eliminate investments in subsidiaries and intercompany balances and transactions between or among the Parent Company, the Guarantor and the Non-Guarantor subsidiaries. Post Holdings, Inc. and all of its domestic subsidiaries form a single consolidated tax group for U.S. income tax purposes. Accordingly, income tax expense has been presented on the Guarantors’ Condensed Statements of Operations using the consolidated U.S. effective tax rate for the Company.

Subsequent Events [Abstract]
Subsequent Events	On October 3, 2016, the Company completed the previously announced acquisition of National Pasteurized Eggs, Inc (“NPE”) for $94.7 , subject to net working capital and other adjustments. NPE is a producer of pasteurized shell eggs, including cage-free and hard boiled eggs. NPE will be combined with Post’s existing Michael Foods egg business. The transaction will be accounted for as a business combination under the acquisition method of accounting. The Company will record the assets acquired and liabilities assumed at their fair values as of the acquisition date. Due to the limited time since closing of the acquisition, the valuation efforts and related acquisition accounting are incomplete at the time of this filing. As a result, the Company is unable to provide amounts recognized as of the acquisition date for major classes of assets and liabilities acquired, including goodwill. In addition, because the acquisition accounting is incomplete, the Company is unable to provide the supplemental pro forma revenue and earnings for the combined entity, as the pro forma adjustments are expected to primarily consist of estimates for the amortization of identifiable intangible assets acquired and related income tax effects which will result from the purchase price allocation and determination of the fair values for the assets acquired and liabilities assumed.

Summary of Significant Accoun31

Summary of Significant Accounting Policies Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Sep. 30, 2016
Accounting Policies [Abstract]
Principles of combination	Principles of Consolidation — The consolidated financial statements include the operations of Post Holdings, Inc. and its wholly-owned subsidiaries. All intercompany transactions have been eliminated.
Use of estimates and allocations	Use of Estimates and Allocations — The consolidated financial statements of the Company are prepared in conformity with accounting principles generally accepted in the United States of America, which require certain elections as to accounting policy, estimates and assumptions that affect the reported amounts of assets, liabilities, the disclosure of contingent liabilities at the dates of the financial statements and the reported amount of net revenues and expenses during the reporting periods. Significant accounting policy elections, estimates and assumptions include, among others, pension and benefit plan assumptions, valuation assumptions of goodwill and other intangible assets, marketing programs, self insurance reserves and income taxes. Actual results could differ from those estimates.
Business combinations	Business Combinations — The Company uses the acquisition method in accounting for acquired businesses. Under the acquisition method, our financial statements reflect the operations of an acquired business starting from the completion of the acquisition. The assets acquired and liabilities assumed are recorded at their respective estimated fair values at the date of the acquisition. Any excess of the purchase price over the estimated fair values of the identifiable net assets acquired is recorded as goodwill.
Cash equivalents	Cash Equivalents — Cash equivalents include all highly liquid investments with original maturities of less than three months.
Restricted cash	Restricted Cash — Restricted cash includes items such as cash deposits which serve as collateral for certain commodity hedging contracts as well as the Company's high deductible workers’ compensation insurance program. In addition, restricted cash includes deposits with third party escrow agents in connection with a recently announced acquisition that will be credited against the purchase price when the transaction closes.
Receivables	Receivables — Receivables are reported at net realizable value. This value includes appropriate allowances for doubtful accounts, cash discounts, and other amounts which the Company does not ultimately expect to collect. The Company determines its allowance for doubtful accounts based on historical losses as well as the economic status of, and its relationship with its customers, especially those identified as “at risk.” A receivable is considered past due if payments have not been received within the agreed upon invoice terms. Receivables are written off against the allowance when the customer files for bankruptcy protection or is otherwise deemed to be uncollectible based upon the Company’s evaluation of the customer’s solvency.
Inventories	Inventories — Inventories, other than flocks, are generally valued at the lower of average cost (determined on a first-in, first-out basis) or market. Reported amounts have been reduced by an allowance for obsolete product and packaging materials based on a review of inventories on hand compared to estimated future usage and sales. Flock inventory represents the cost of purchasing and raising chicken flocks to egg laying maturity. The costs included in our flock inventory include the costs of the chicks, the feed fed to the birds and the labor and overhead costs incurred to operate the pullet facilities until the birds are transferred into the laying facilities, at which time their cost is amortized to operations, as cost of goods sold, over their expected useful lives of one to two years.
Restructuring Expenses and Assets Held-for-sale	Restructuring Expenses and Assets Held For Sale — Restructuring charges principally consist of severance, accelerated stock compensation and other employee separation costs, accelerated depreciation and certain long-lived asset impairments. The Company recognizes restructuring obligations and liabilities for exit and disposal activities at fair value in the period the liability is incurred. Employee severance costs are expensed when they become probable and reasonably estimable under established severance plans. Depreciation expense related to assets that will be disposed of or idled as a part of the restructuring activity is accelerated through the expected date of the asset shut down. Assets are classified as held for sale if the Company has committed to a plan for selling the assets, is actively and reasonably marketing them, and sale is reasonably expected within one year. The carrying value of assets held for sale is included in “Prepaid expenses and other current assets” on the Consolidated Balance Sheets. See Note 4 for information about restructuring expenses and assets held for sale.
Property	Property — Property is recorded at cost, and depreciation expense is generally provided on a straight-line basis over the estimated useful lives of the properties. Estimated useful lives range from 1 to 20 years for machinery and equipment and 3 to 40 years for buildings, building improvements and leasehold improvements, and 1 to 5 years for software. Total depreciation expense was $150.2 , $131.1 and $85.0 in fiscal 2016 , 2015 and 2014 , respectively. Any gains and losses incurred on the sale or disposal of assets are included in "Other operating expenses, net” in the Consolidated Statements of Operations. Repair and maintenance costs incurred in connection with on-going and planned major maintenance activities are accounted for under the direct expensing method. During the year ended September 30, 2015, the Company had non-monetary exchanges of fixed assets. The cash and non-cash portions of these transactions were $9.8 and $12.6 , respectively. Property consisted of: September 30, 2016 2015 Land and land improvements $ 58.0 $ 52.8 Buildings and leasehold improvements 618.2 591.3 Machinery and equipment 1,094.5 1,006.4 Software 50.4 49.2 Construction in progress 79.2 38.0 1,900.3 1,737.7 Accumulated depreciation (545.9 ) (404.5 ) $ 1,354.4 $ 1,333.2
Other intangible assets	Other Intangible Assets — Other intangible assets consist primarily of customer relationships and trademarks/brands acquired in business combinations and includes both indefinite and definite-lived assets. Amortization expense related to definite-lived intangible assets, which is provided on a straight-line basis over the estimated useful lives of the assets, was $152.6 , $141.7 , and $70.8 in fiscal 2016 , 2015 and 2014 , respectively. For the definite-lived intangible assets recorded as of September 30, 2016 , amortization expense of $152.6 , $152.6 , $151.7 , $151.7 and $151.7 is scheduled for fiscal 2017 , 2018 , 2019 , 2020 and 2021 , respectively. Other intangible assets consisted of: September 30, 2016 September 30, 2015 Carrying Amount Accum. Amort. Net Amount Carrying Amount Accum. Amort. Net Amount Subject to amortization: Customer relationships $ 2,012.7 $ (302.0 ) $ 1,710.7 $ 1,998.6 $ (192.7 ) $ 1,805.9 Trademarks/brands 795.1 (120.6 ) 674.5 780.9 (79.1 ) 701.8 Other 21.7 (7.7 ) 14.0 21.3 (5.4 ) 15.9 2,829.5 (430.3 ) 2,399.2 2,800.8 (277.2 ) 2,523.6 Not subject to amortization: Trademarks/brands 434.5 — 434.5 445.7 — 445.7 $ 3,264.0 $ (430.3 ) $ 2,833.7 $ 3,246.5 $ (277.2 ) $ 2,969.3
Recoverability of assets	Recoverability of Assets — The Company continually evaluates whether events or circumstances have occurred which might impair the recoverability of the carrying value of its assets, including property, identifiable intangibles and goodwill. Trademarks with indefinite lives are reviewed for impairment during the fourth quarter of each fiscal year following the annual forecasting process, or more frequently if facts and circumstances indicate the trademark may be impaired. The trademark impairment tests require us to estimate the fair value of the trademark and compare it to its carrying value. The estimated fair value is determined using an income-based approach (the relief-from-royalty method), which requires significant assumptions for each brand, including estimates regarding future revenue growth, discount rates, and appropriate royalty rates. Assumptions are determined after consideration of several factors for each brand, including profit levels, research of external royalty rates by third party experts and the relative importance of each brand to the Company. Revenue growth assumptions are based on historical trends and management’s expectations for future growth by brand. The discount rate is based on a weighted-average cost of capital utilizing industry market data of similar companies. In addition, definite-lived assets and indefinite-lived intangible assets are reassessed as needed when information becomes available that is believed to negatively impact the fair market value of an asset. In general, an asset is deemed impaired and written down to its fair value if estimated related future cash flows are less than its carrying amount. See Note 6 for information about goodwill impairments. For the year ended September 30, 2016, the Company conducted an impairment review and concluded there was no impairment of intangible assets as of September 30, 2016. At September 30, 2016, the estimated fair values of all intangible assets exceeded their carrying value by at least 36% . At September 30, 2015, Post recorded impairment losses in the Post Consumer Brands Segment of $3.7 for the Grape-Nuts brand and $0.1 for the 100% Bran brand to record these trademarks at their estimated current fair values of $11.2 and zero , respectively. Due to repeated past impairments, continued weakness in the brand forecasts and a lack of sales growth from recent brand support efforts, as of October, 1 2015, the Grape-Nuts brand was converted to a definite-lived asset and assigned a 20 year useful life. At September 30, 2014, Post recorded impairment losses in the Post Consumer Brands segment of $34.4 for the Post brand, $23.0 for the Honey Bunches of Oats brand, $17.2 for the Post Shredded Wheat brand and $8.4 for the Grape-Nuts brand to record these trademarks at their estimated current fair values of $144.0 , $243.9 , $8.2 and $14.9 , respectively. Due to repeated past impairments, continued weakness in the brand forecasts and a lack of sales growth from recent brand support efforts, as of October 1, 2014, the Post Shredded Wheat brand was converted to a definite-lived asset and assigned a 20 year useful life. These fair value measurements fell within Level 3 of the fair value hierarchy as described in Note 13. The trademark and goodwill impairment losses are reported in “Impairment of goodwill and other intangible assets” on the Consolidated Statements of Operations.
Investments	Investments — The Company funds a portion of its deferred compensation liability by investing in certain mutual funds in the same amounts as selected by the participating employees. Because management’s intent is to invest in a manner that matches the deferral options chosen by the participants and those participants can elect to transfer amounts in or out of each of the designated deferral options at any time, these investments have been classified as trading assets and are stated at fair value in “Prepaid expenses and other current assets” and “Other Assets” (see Note 13). Both realized and unrealized gains and losses on these assets are included in “Selling, general and administrative expenses” and offset the related change in the deferred compensation liability.
Revenue	Revenue — Revenue is recognized when title of goods and risk of loss is transferred to the customer, as specified by the shipping terms. Net sales reflect gross sales, including amounts billed to customers for shipping and handling, less sales discounts and trade allowances (including promotional price buy downs and new item promotional funding). Customer trade allowances are generally computed as a percentage of gross sales. Products are generally sold with no right of return except in the case of goods which do not meet product specifications or are damaged, and related reserves are maintained based on return history. If additional rights of return are granted, revenue recognition is deferred. Estimated reductions to revenue for customer incentive offerings are based upon customer redemption history.
Cost of products sold	Cost of Goods Sold — Cost of goods sold includes, among other things, inbound and outbound freight costs and depreciation expense related to assets used in production, while storage and other warehousing costs are included in “Selling, general and administrative expenses.” Storage and other warehousing costs totaled $ 124.1 , $ 103.4 and $ 65.4 in fiscal 2016 , 2015 and 2014 , respectively.
Advertising	Advertising — Advertising costs are expensed as incurred except for costs of producing media advertising such as television commercials or magazine advertisements, which are deferred until the first time the advertising takes place. The amounts reported as assets on the balance sheet were $1.6 and $1.4 as of September 30, 2016 and 2015 , respectively.
Stock-based compensation	Stock-based Compensation — The Company recognizes the cost of employee services received in exchange for awards of equity instruments based on the grant-date fair value of equity awards and the fair market value at each quarterly reporting date for liability awards. That cost is recognized over the period during which an employee is required to provide service in exchange for the award — the requisite service period (usually the vesting period). See Note 17 for disclosures related to stock-based compensation.
Income tax expense	Income Tax (Benefit) Provision — Income tax (benefit) provision is estimated based on income taxes in each jurisdiction and includes the effects of both current tax exposures and the temporary differences resulting from differing treatment of items for tax and financial reporting purposes. These temporary differences result in deferred tax assets and liabilities. A valuation allowance is established against the related deferred tax assets to the extent that it is not more likely than not that the future benefits will be realized. Reserves are recorded for estimated exposures associated with the Company’s tax filing positions, which are subject to periodic audits by governmental taxing authorities. Interest due to an underpayment of income taxes is classified as income taxes. The Company considers the undistributed earnings of its foreign subsidiaries to be permanently reinvested, so no U.S. taxes have been provided in relation to the Company's investment in its foreign subsidiaries. See Note 7 for disclosures related to income taxes.
