NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

(in millions, except per share information and where indicated otherwise)

Note 1 — Background

Post Holdings, Inc. (“Post” or the “Company”) is a manufacturer, marketer and distributor of branded ready-to-eat cereals in the United States and Canada. Post’s products are generally sold to supermarket chains, wholesalers, supercenters, club stores, mass merchandisers, distributors, convenience stores and the foodservice channel in North America. The Company's products are primarily manufactured at four facilities located in Battle Creek, Michigan; Jonesboro, Arkansas; Modesto, California; and Niagara Falls, Ontario.

On February 3, 2012, Post completed its legal separation via a tax free spin-off (the “Spin-Off”) from Ralcorp Holdings, Inc., which was acquired by ConAgra Foods, Inc. on January 29, 2013 (“Ralcorp”) . On February 6, 2012, Post began regular trading on the New York Stock Exchange under the ticker symbol “POST” as an independent, public company.

Post has a single operating segment and manufactures and markets products under several brand names, including Honey Bunches of Oats^®, Pebbles™, Post Selects^®, Great Grains^®, Spoon Size^® Shredded Wheat, Post^® Raisin Bran, Grape-Nuts^® and Honeycomb^®. With the acquisition of substantially all of the assets of Attune Foods, Inc. on December 31, 2012 (see Note 3), Post's portfolio of brands now also includes Attune^®, Uncle Sam^® and Erewhon^®.

Unless otherwise stated or the context otherwise indicates, all references in this Form 10-Q to “Post,” “the Company,” “us,” “our” or “we” mean Post Holdings, Inc. and its consolidated subsidiaries, and for periods prior to the Spin-Off from Ralcorp, the Branded Cereal Business of Ralcorp.

Basis of Presentation

These unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”), under the rules and regulations of the United States Securities and Exchange Commission (the “SEC”), and on a basis substantially consistent with the audited consolidated financial statements of the Company as of and for the fiscal year ended September 30, 2012. These unaudited condensed consolidated financial statements should be read in conjunction with such audited consolidated financial statements, which are included in the Company’s Annual Report on Form 10-K filed with the SEC on December 13, 2012.

These unaudited condensed consolidated financial statements include all adjustments (consisting of normal recurring adjustments and accruals) that management considers necessary for a fair statement of its financial position, results of operations, comprehensive income and cash flows for the interim periods presented. Interim results are not necessarily indicative of the results for any other interim period or for the entire fiscal year.

Prior to the Spin-Off, Post's operations consisted of the Branded Cereals Business of Ralcorp. As such, the financial information prior to the Spin-Off may not necessarily reflect Post's financial position, results of operations, comprehensive income and cash flows had Post been an independent, publicly-traded company for the entirety of the three and six months ended March 31, 2012, as presented herein.

For periods prior to the Spin-Off, these unaudited condensed consolidated financial statements include allocations of certain Ralcorp corporate expenses. Management believes the assumptions and methodologies underlying the allocation of general corporate overhead expenses are reasonable. However, such expenses may not be indicative of the actual level of expense that would have been incurred by Post if it had operated as an independent, publicly-traded company. These allocated expenses relate to various services that were provided to Post by Ralcorp, including, but not limited to, cash management and other treasury services, administrative services (such as tax, employee benefit administration, risk management, internal audit, accounting and human resources) and stock-based compensation plan administration. See Note 15 for further information on services that Ralcorp continues to provide to the Company.

The financial position and operating results of foreign operations are consolidated using the local currency as the functional currency. Local currency assets and liabilities are translated at the rates of exchange on the balance sheet date, and local currency revenues and expenses are translated at average rates of exchange during the period. Resulting translation gains or losses are included in the condensed consolidated balance sheet as a component of accumulated other comprehensive loss.

Use of Estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported in the condensed consolidated financial statements and footnotes thereto. Actual results could differ from those estimates. Significant estimates inherent in the preparation of the condensed consolidated financial statements include accounting for reserves established for doubtful accounts, stock-based compensation, impairment analyses, depreciation and amortization, income taxes, litigation matters and contingencies.

5

Revision

In the preparation of the financial statements for the year ended September 30, 2012, the Company identified errors within the statements of cash flows for the six months ended March 31, 2012. The Company concluded the errors were not material to the previously reported interim financial statements. Accordingly, the Company has revised its 2012 comparative statements of cash flows included herein. The revisions are required to correct errors in the calculation of adjustments to the statements of cash flows that related to the Company's separation from Ralcorp on February 3, 2012. The impact of the revision was to increase net cash flows from operations and decrease net cash flows from financing activities by $10.0. The six month net cash flow from operations changed from $67.1 to $77.1.  The net cash flow from financing activities for the six months changed from $10.7 to $0.7. The errors did not impact the consolidated statements of operations and comprehensive income/(loss) for the three and six months ended March 31, 2012.

Note 2 — Recently Issued Accounting Standards

On January 31, 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-01, "Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities," which provides scope clarifications related to the previously issued ASU 2011- 11. These ASU's provide new requirements for disclosures about instruments and transactions eligible for offset in the statement of financial position, as well as instruments and transactions subject to an agreement similar to a master netting arrangement. The amendments in these updates are effective for annual reporting periods beginning on or after January 1, 2013 (i.e., Post's financial statements for the year ending September 30, 2014), and interim periods within those annual periods. The adoption of this update is not expected to have a material effect on Post's financial position, results of operations or cash flows.

On February 5, 2013, the FASB issued ASU 2013-02, "Reporting Amounts Reclassified out of Accumulated Other Comprehensive Income," which requires additional disclosure of amounts recorded in Accumulated Other Comprehensive Income and amounts that are reclassified from Accumulated Other Comprehensive Income. This update is effective for fiscal years beginning after December 15, 2012 (i.e., Post's financial statements for the year ending September 30, 2014), and interim periods within those annual periods. The adoption of this update is not expected to have a material effect on Post's financial position, results of operations or cash flows.

Note 3 — Business Combinations

On December 31, 2012, Post Foods, LLC, a subsidiary of the Company, purchased substantially all of the assets of Attune Foods, Inc. (“Attune”), a manufacturer and marketer of branded premium healthy and organic cereals and snacks headquartered in San Francisco, California, for approximately $9.2.

Based upon the Company's valuation, the following reflects the fair value of assets acquired and liabilities assumed in the transaction:

Receivables	$	0.5
Inventories	2.6
Prepaid expenses and other current assets	0.1
Property	0.1
Goodwill	3.6
Other intangible assets	3.8

Acquisition of Attune Foods, Inc.	3.6
Currency translation adjustment	(0.2		)
Balance, March 31, 2013	$	1,370.0

6

As discussed in Note 3, on December 31, 2012, the Company closed on an asset purchase agreement to acquire substantially all of the assets of Attune. Based upon the purchase price allocation the Company has recorded $3.6 of goodwill related to the acquisition.

Note 5 — Intangible Assets, net

Total intangible assets are as follows:

	March 31, 2013							September 30, 2012
	Carrying Amount		Accumulated Amortization			Net Amount		Carrying Amount		Accumulated Amortization			Net Amount

	$	792.3	$	(58.9	)	$	733.4	$	788.5	$	(52.5	)	$	736.0

Based upon the purchase price allocation for the Attune acquisition, the Company has recorded $2.7 and $1.1 of customer relationships and trademarks/brands, respectively. See Note 3 for further discussion.

Note 6 – Earnings per Share

Basic earnings per share is based on the average number of common shares outstanding during the period. Diluted earnings per share is based on the average number of shares used for the basic earnings per share calculation, adjusted for the dilutive effect of stock options, stock appreciation rights and restricted stock equivalents using the "treasury stock" method. The impact of potentially dilutive convertible preferred stock is calculated using the "if-converted" method. For the three and six months ended March 31, 2012, the computation of basic and diluted earnings per common share is calculated assuming the number of shares of Post common stock outstanding on February 3, 2012 had been outstanding at the beginning of the period.

The following table sets forth the computation of basic and diluted earnings per share for the three and six months ended March 31, 2013 and 2012, respectively.

	Three months ended March 31,					Six months ended March 31,
	2013			2012		2013			2012
Net earnings	$	5.1		$	10.5	$	12.7		$	23.3

Diluted earnings per common share	$	0.13		$	0.30	$	0.36		$	0.68

For the three and six months ended March 31, 2013, weighted-average shares for diluted earnings per common share excludes 0.6 million and 2.2 million equity awards, respectively and 5.1 million shares related to the potential conversion of the Company's convertible preferred stock, see Note 11, for both the three and six months ended March 31, 2013 as they were anti-dilutive.

Note 9 — 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 debt, and foreign currency exchange rate risks relating to its foreign subsidiary. 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.

8

Prior to the Spin-Off, Post participated in Ralcorp's derivative instrument program which consisted of commodity contracts (options, futures, and swaps) on raw material and fuel purchases. Prior to the Spin-Off date, Post no longer participated in the Ralcorp derivative instrument program. Derivative instrument gains and losses are included in “cost of goods sold” for all periods presented.

The Company maintains options and futures contracts which have been designated as economic hedges of raw materials and fuel purchases. The following table presents the balance sheet location and fair value of the Company's derivative instruments.

		Fair Value
Derivative Instrument	Balance Sheet Location	March 31, 2013		September 30, 2012
Commodity contracts	Prepaid expenses and other current assets	$	0.1	$	1.3
Natural gas futures	Prepaid expenses and other current assets	0.3		0.3
		$	0.4	$	1.6

The following table presents the loss from derivative instruments that were not designated as hedging instruments which were recorded on the Company's Statement of Operations.

		Three months ended March 31,						Six months ended March 31,

Commodity contracts	Cost of goods sold	0.3			—			0.8		—

Note 10 — Fair Value Measurements

The following table represents Post's assets and liabilities measured at fair value on a recurring basis and the basis for that measurement according to the levels in the fair value hierarchy in ASC Topic 820:

	March 31, 2013						September 30, 2012
	Total		Level 1		Level 2		Total		Level 1		Level 2
Deferred compensation investment	$	7.6	$	7.6	$	—	$	1.4	$	1.4	$	—
Derivative instruments	0.4		—		0.4		1.6		—		1.6
Deferred compensation liabilities	12.4		—		12.4		8.6		—		8.6

The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity's pricing based upon their own market assumptions. The fair value hierarchy consists of three levels: 

Level 1 — Inputs are quoted prices in active markets for identical assets or liabilities.

Level 2 — Inputs are quoted prices of similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.

Level 3 — Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The deferred compensation investment is invested primarily in mutual funds and is measured using the market approach. This investment is in the same funds and purchased in substantially the same amounts as the participants' selected investment options (excluding Post and Ralcorp 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.

9

Changes in the fair value of assets and liabilities measured at fair value on a recurring basis are recorded as a component of selling, general and administrative expense, except for derivative instruments which are recorded in cost of goods sold.

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 of these financial instruments. The fair value of long-term debt as of March 31, 2013 (see Note 12) is approximately$1,121.1 based on quoted market prices for the Company's senior notes.

Note 11 - Preferred Stock

In February 2013, the Company authorized and issued 2.4 million shares of its 3.75%Series B Cumulative Perpetual Convertible Preferred Stock. The Company received net proceeds of $234.1 after paying offering related fees and expenses of $7.4. The preferred stock has a $0.01 par value and a $100.00 liquidation value. The preferred stock earns cumulative dividends at a rate 3.75% per annum payable quarterly on February 15, May 15, August 15 and November 15, beginning on May 15, 2013. The preferred stock is non-voting and ranks senior to our outstanding common stock upon the Company's dissolution or liquidation. The preferred stock has no maturity date; however, holders of the preferred stock may convert their preferred 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. Additionally, on or after February 15, 2018, the Company will have the option to redeem some or all the preferred stock at a redemption price equal to 100% of the liquidation preference per share, plus accrued and unpaid dividends if the closing sale price of the Company's common stock has been at least 130% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period.

Note 12 - Long Term Debt

Long-term debt as of the dates indicated consists of the following:

	March 31, 2013		September 30, 2012
7.375% Senior Notes maturing February 2022, including net premium (1)	$	1,039.5	$	775.0
Term Loan maturing 2017	—		170.6
Revolving Credit Facility (2)	—		—
	$	1,039.5	$	945.6
Less: Current Portion	—		(15.3		)
Total long-term debt	$	1,039.5	$	930.3

(1) - On October 25, 2012, the Company issued an incremental $250.0 principal value of its 7.375% Senior Notes at 106% of par value

(2) - The revolving credit facility has an outstanding letter of credit of $1.1 which reduces available borrowing capacity to $173.9 as of March 31, 2013.

As of March 31, 2013, the Company has $1,039.5 outstanding of its 7.375% senior notes (the “Notes”) due in 2022 which includes an unamortized premium of $14.5. The premium is amortized as a reduction to interest expense over the term of the Notes.The Notes were issued pursuant to an indenture among the Company, Post Foods, LLC, as guarantor, and Wells Fargo Bank, National Association, as trustee. Interest payments on the Notes are due semi-annually each February 15 and August 15. The maturity date of the Notes is February 15, 2022.

The Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by each of our existing and future domestic subsidiaries (other than immaterial subsidiaries or receivables finance subsidiaries). As of March 31, 2013, our only domestic subsidiary (and therefore the only subsidiary guarantor) was Post Foods, LLC. Our foreign subsidiaries do not guarantee the notes. These guarantees are subject to release in limited circumstances (only upon the occurrence of certain customary conditions).

The Company maintains a senior secured credit facility, as amended, (the “Credit Facility”) which provides for (i) a revolving credit facility with $175.0 of borrowing capacity and (ii) a term loan facility. On February 28, 2013, the Company paid the remaining principal and accrued interest on the term loan facility using the proceeds from our preferred stock issuance, see Note 11. As of March 31, 2013, the Company has no principal obligations due under Credit Facility whose term expires on February 3, 2017.

Borrowings under the Credit Facility bear interest at LIBOR or a base rate (as defined in the Credit Facility) plus an applicable margin ranging from 1.50% to 2.00% for LIBOR-based loans and from 0.50% to 1.00% for Base Rate-based loans, depending upon the Company's consolidated leverage ratio.

10

The Credit Facility contains customary affirmative and negative covenants for agreements of this type. The Credit Facility also contains customary financial covenants including (i) a maximum consolidated leverage ratio of 5.75 to 1.00 and stepping down to, 5.50 to 1.00 on October 1, 2013, 5.25 to 1.00 on October 1, 2014 and 5.00 to 1.00 on October 1, 2015, and (ii) a minimum interest expense coverage ratio initially set at 2.50 to 1.00 and then increasing to 2.75 to 1.00 on October 1, 2014.

The Credit Facility 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, the occurrence of certain judgments or attachments in excess of $25.0, change in control and certain ERISA events. Upon the occurrence of an event of default, and at the request of lenders holding more than 50% in principal amount of lender commitments and outstanding loans under the Credit Facility will cause the maturity of the loans to be accelerated.

The Company's obligations under the Credit Facility are unconditionally guaranteed by each of its existing and subsequently acquired or organized domestic subsidiaries. As of this date, the only domestic subsidiary (and therefore the only subsidiary guarantor) is Post Foods, LLC. The Credit Facility is secured by security interests and liens on substantially all of the assets of the Company and Post Foods, LLC.

Note 13 — Pension and Other Postretirement Benefits

Stock options granted during the six months ended March 31, 2013 had an aggregate grant date fair value of $3.5. Restricted stock units granted during the six months ended March 31, 2013 had an aggregate grant date fair value of $1.9. The grant date fair value of both the stock options and restricted stock units is expected to be recognized over a weighted-average period of 5.7 years. Cash settled restricted stock units granted during the six months ended March 31, 2013 had an aggregate grant date fair value of $0.3. The expense related to these awards, which is expected to be recognized over a weighted-average period of 3.0 years, will be adjusted each reporting period based on the period end fair value of the awards. During the six months ended March 31, 2013, the Company issued stock settled stock appreciation rights to non-management members of the board of directors. These awards had a grant date fair value of $0.4 which was expensed upon issuance due to vesting provisions of these awards.

Note 15 — Transactions with Former Owner

Prior to the Spin-Off, Post operated under Ralcorp's centralized cash management system, Post's cash requirements were provided directly by Ralcorp, and cash generated by Post was generally remitted directly to Ralcorp. Transaction systems (e.g. payroll, employee benefits and accounts payable) used to record and account for cash disbursements were generally provided by Ralcorp. Ralcorp also provided centralized demand planning, order management, billing, credit and collection services to Post. Transaction systems (e.g. revenues, accounts receivable and cash application) used to record and account for cash receipts were generally provided by centralized Ralcorp organizations. These Ralcorp systems were generally designed to track assets/liabilities and receipts/payments on a business specific basis. After the Spin-Off, Ralcorp continues to provide certain of these services to Post under a transition services agreement (“TSA”) between the companies.

For periods prior to the Spin-Off, costs and expenses in the accompanying condensed consolidated statements of operations represent direct and allocated costs and expenses related to Post. Costs for certain functions and services performed by centralized Ralcorp organizations were allocated to Post based upon reasonable activity bases (generally volume, revenues, net assets or a combination as compared to the total of Ralcorp and Post amounts) or other reasonable methods. The condensed consolidated statements of operations include expense allocations for certain manufacturing, shipping, distribution and administration costs including information systems, procurement, accounting shared services, legal, tax, human resources, payroll, credit and accounts receivable, customer service and cash management. For the three and six months ended March 31, 2012, total allocated costs were $0.8 and $4.6, respectively, which were reported in “selling, general and administrative expenses.” After the Spin-Off, costs for services provided by Ralcorp are based on agreed upon fees contained in the TSA. TSA charges were $1.5, $2.2, $3.1, and $2.2 for the three and six months ended March 31, 2013 and 2012, respectively, and were reported in “selling, general and administrative expenses.”

Post produces certain products for sale to Ralcorp. For periods prior to the Spin-Off, the amounts related to these transactions have been included in the accompanying financial statements based upon transfer prices in effect at the time of the individual transactions which were consistent with prices of similar arm's-length transactions. For periods subsequent to the Spin-Off, these transactions were based upon pricing governed by the TSA with Ralcorp. Net sales related to those transactions was $3.5, $3.4, $7.5 and $8.4 in the three and six months ended March 31, 2013 and 2012, respectively.

In connection with the Spin-Off, the Company entered into a series of agreements with Ralcorp which are intended to govern the relationship between the Company and Ralcorp and to facilitate an orderly separation of the Company from Ralcorp. These agreements include a Separation and Distribution Agreement, Tax Allocation Agreement and the TSA, among others. Additionally, the Company has agreed to indemnify Ralcorp for income taxes incurred if the Company violates certain provisions of the IRS private letter ruling obtained by Ralcorp. Under certain of these agreements, the Company will incur

12

expenses payable to Ralcorp in connection with certain administrative services provided for varying lengths of time. The Company incurred separation related costs of $2.4, $5.3, $5.2 and $8.0 during the three and six months ended March 31, 2013 and 2012, respectively. The costs incurred were primarily related to professional service fees to effect the Spin-Off and professional service fees and duplicative costs incurred by Post to establish stand-alone processes and systems for activities performed by Ralcorp under the TSA. These costs were reported as a component of “Selling, general and administrative expenses.” See Note 1 for additional information on the Spin-Off. As of March 31, 2013, the Company has a $3.7 net receivable related to the net transactions from these agreements.

Note 16 — Information About Geographic Areas and Major Customers

Products sold can be grouped into three primary categories of cereals: balanced, sweetened and unsweetened. Net sales by category are shown in the following table.

	Three months ended March 31,				Six months ended March 31,
	2013		2012		2013		2012
Balanced	$	150.7	$	149.3	$	292.3	$	277.0
Sweetened	61.2		63.3		120.7		119.6
Unsweetened	36.3		37.9		72.1		73.2
	$	248.2	$	250.5	$	485.1	$	469.8

Post's external revenues were primarily generated by sales within the United States; foreign (primarily Canadian) sales were approximately 12% and 14% of total net sales for the three and six months ended March 31, 2013, respectively. Sales are attributed to individual countries based on the address to which the product is shipped.

As of March 31, 2013, the majority of Post's tangible long-lived assets were located in the United States; the remainder is located in Canada and has a net carrying value of approximately $48.5.

During the three and six months ended March 31, 2013 and 2012, one customer accounted for $49.6, $52.0, $105.0 and $99.8, respectively, or approximately 20%, 21%, 22% and 21% respectively, of total net sales.

Note 17 — Condensed Financial Statements of Guarantors

The Company issued the Notes in an aggregate principal amount of $1,025.0. The Notes were issued pursuant to an indenture dated as of February 3, 2012 among the Company, Post Foods, LLC, as guarantor, and Wells Fargo Bank, National Association, as trustee.

The Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by each of our existing and future domestic subsidiaries, the “Guarantors.” Our foreign subsidiaries, the “Non-Guarantors,” will not guarantee the 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 Post Holdings, Inc., the “Parent Company”, 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 Foods, LLC, currently the Company's sole domestic subsidiary, is a disregarded entity for U.S. income tax purposes, therefore income tax expense has been presented on the Guarantors' Condensed Statements of Operations using the U.S. effective tax rate for the Company. Income tax payable and deferred tax items for the consolidated U.S. tax paying group reside solely on the Parent Company's Condensed Balance Sheet. For periods prior to February 3, 2012, the Parent Company had no operations and therefore no Parent Company financial information is presented for those periods and accordingly the equity earnings of the Parent Company will not equal the earnings of the subsidiaries.

Recent Events

Preferred Stock Issuance

On February 26, 2013, we issued 2.4 million shares of our 3.75% Series B Cumulative Perpetual Convertible Preferred Stock. We received net proceeds of $234.1 million after paying offering related fees and expenses of $7.4 million. On February 28, 2013, we used a portion of these proceeds to repay the remaining principal balance on our term loan of $168.4 million.

On April 24, 2013, our Board of Directors declared a quarterly dividend of $0.8125 per share, representing a pro-rata payment for the partial dividend period from the issue date of February 26, 2013 to May 14, 2013, on our 3.75% Series B Cumulative Perpetual Convertible Preferred Stock.  The dividend will be paid on May 15, 2013 to preferred shareholders as of record date May 1, 2013.

Modesto Plant Shut-down

On April 4, 2013, we announced management's decision to close our manufacturing facility located in Modesto, California. The Modesto plant has approximately 140 employees. The transfer of production capabilities and closure of the plant is expected to be completed by September 2014.

Upon completion of the transfer and start-up of production to other facilities, which is estimated to require capital expenditures of approximately $29.8 million, we expect to achieve net pretax annual cash manufacturing cost savings of approximately $14.0 million.

Acquisition of certain assets of Hearthside Foods

On May 9, 2013, we announced the signing of a definitive agreement to acquire the branded and private label cereal, granola and snacks business of Hearthside Food Solutions for $158.0, subject to a working capital adjustment. We anticipate completing the all cash transaction by June 2013, subject to certain limited closing conditions including the expiration of waiting periods required under antitrust laws and the receipt of necessary third party consents.

Results of Operations

The following discussion compares our summarized operating results for the three months ended March 31, 2013 and 2012.

The following table summarizes operational results for the periods indicated (dollars in millions).

	Three months ended March 31,
	2013		2012
Net Sales	$	248.2	$	250.5
Operating Profit	28.9		33.2
Net Earnings	5.1		10.5

22

Net Sales

Percentage volume changes for the three months ended March 31, 2013 relative to comparable amounts for the prior year period were as follows:

	Three months ended March 31, 2013
Honey Bunches of Oats	(9	)%
Pebbles	(3	)%
Other	19	%
Total	3	%

Net sales for the three months ended March 31, 2013 decreased $2.3 million or 0.9% compared to prior year. This decrease was primarily driven by a 3% improvement in overall volumes which was offset by a 4% decrease in average net selling prices. For the three months ended March 31, 2013 the improved volumes were primarily driven by increases from our Great Grains and Grape Nuts brands which increased 15% and 13%, respectively and volumes from co-manufactured products and for our recently introduced Good Morenings brand products. The decline in Honey Bunches of Oats volumes resulted from an increase in prior quarter shipments, primarily related new product extensions, that reduced shipping volumes in the current period. The decrease in average net selling prices was primarily the result of higher trade and promotion spending, which included higher slotting fees resulting from a higher level of new product introductions in the current year, volume shifts to larger package sizes and increases in co-manufactured product sales and sales of our Good Morenings brand cereals which sell at a lower price point.

Margins

	Three months ended March 31,
	2013		2012
	(% of net sales)
Gross Profit	41.3	%	44.3	%
Selling, General and Administrative Expenses	28.2	%	29.6	%
Operating Profit	11.6	%	13.3	%

Gross profit margins decreased by 3.0 percentage points in 2013 compared to 2012. Gross profit margin declines were driven by $10.6 million of unfavorable net pricing primarily from a product mix shift to lower margin products and higher trade spending and $0.9 million of higher raw material costs (primarily grains and fruits partially offset by lower sugar costs). These cost increases were partially offset by $1.3 million of favorable manufacturing costs due to favorable fixed cost absorption on higher production volumes and ingredient mix.

Selling, general and administrative expenses (“SG&A”) as a percentage of net sales decreased 1.4 percentage points when compared to the prior year quarter. The decrease was driven by reduced advertising and promotion costs of $8.5 million which was partially offset by $5.3 million of incremental holding company costs incurred in the second quarter of fiscal 2013 to support Post as an independent publicly traded company.

Operating profit as a percentage of net sales decreased to 11.6% from 13.3%. This decrease was primarily driven by margin compression in the current year due to decreases in gross profit margin as previously described.

Interest Expense

Interest expense was $21.6 million for the three months ended March 31, 2013, compared to $15.1 million for the three months ended March 31, 2012. The increase is driven primarily by the $250.0 million increase in outstanding debt through the issuance of our Senior Notes in October 2012 and the increased debt incurred at the time of our spin-off from Ralcorp in February 2012. Additionally, interest expense for the three months ended March 31, 2013 includes the write-off of approximately $1.6 million of deferred financing costs associated with our term loan which was paid in full on February 28, 2013.

Income Taxes

Income tax expense was $2.2 million, which represents an effective income tax rate of 30.1%, for the three months ended March 31, 2013, compared to expense of $8.6 million and an effective income tax rate of 45.0%, for the three months ended March 31, 2012.

23

The effective tax rate for fiscal 2013 is favorably impacted, as compared to statutory tax rates, by the effects of the Domestic Production Activities Deduction (“DPAD”). The DPAD is a U.S. federal deduction of a percentage of taxable income from domestic manufacturing. The amount of the DPAD is affected not only by pre-tax book income, but also temporary differences in the timing and amounts of certain tax deductions including depreciation of property and post retirement benefits. The effective tax rate for fiscal 2013 was also favorably impacted by an estimated fiscal 2012 research and development credit which was retroactively reinstated by legislation enacted in January 2013. The effective tax rate for fiscal 2012 was unfavorably impacted by $4.6 million of non-deductible transaction expenses, which resulted in $1.8 million of incremental tax expense, incurred to effect our separation from Ralcorp.

The following discussion compares our summarized operating results for the six months ended March 31, 2013 and 2012.

The following table summarizes operational results for the periods indicated (dollars in millions).

	Six months ended March 31,
	2013		2012
Net Sales	$	485.1	$	469.8
Operating Profit	59.2		64.5
Net Earnings	12.7		23.3

Net Sales

Percentage volume changes for the six months ended March 31, 2013 relative to comparable amounts for the prior year period were as follows:

	Six months ended March 31, 2013
Honey Bunches of Oats	(3	)%
Pebbles	1	%
Other	14	%
Total	5	%

Net sales for the six months ended March 31, 2013 increased $15.3 million or 3% compared to prior year. This increase was primarily driven by a 5% improvement in overall volumes and slightly lower average net selling prices. For the six months ended March 31, 2013 the improved volumes were primarily driven by increases in sales of co-manufactured products and our Good Morenings,Great Grains and Grape Nuts brands. The decrease in average net selling prices was primarily the result of increased trade spending primarily related to increased slotting fees on new product introductions in the current year and a shift in product mix to products with lower average gross selling prices, partially offset by lower coupon redemption.

Margins

	Six months ended March 31,
	2013		2012
	(% of net sales)
Gross Profit	42.9	%	44.5	%
Selling, General and Administrative Expenses	29.3	%	29.3	%
Operating Profit	12.2	%	13.7	%

Gross profit margins decreased by 1.6 percentage points in 2013 compared to 2012. Gross profit margin declines were driven by $6.8 million of higher raw material costs (primarily grains and fruits partially offset by favorable sugar costs) and unfavorable net pricing. These unfavorable factors were partially offset by $5.3 million of favorable manufacturing costs due to favorable ingredient mix.

SG&A as a percentage of net sales was 29.3% for both the six months ended March 31, 2013 and 2012. For the six months ended March 31, 2013, the overall SG&A expenses increased $4.5 million compared to the prior year on

24

incremental holding company costs of $13.7 million to support Post as an independent publicly traded company. These increases were partially offset by a $9.2 million reduction in advertising and promotion expense and a $2.8 million decrease in our costs to effect our separation from Ralcorp.

Operating profit as a percentage of net sales decreased to 12.2% from 13.7%. This decrease was primarily driven by margin compression in the current year due to decreases in gross profit margin as previously described.

Interest Expense

Interest expense was $40.8 million for the six months ended March 31, 2013, compared to $28.1 million for the six months ended March 31, 2012. The increase is driven primarily by debt incurred at the time of our spin-off from Ralcorp in February 2012 and the $250.0 million increase in outstanding debt through the issuance of our Senior Notes in October 2012. Additionally, for periods in the prior year before the spin-off interest expense was related to debt obligations of Ralcorp which were assumed from Kraft in the August 2008 acquisition of Post. These debt obligations were settled at the time of our separation from Ralcorp.

Income Taxes

Income tax expense was $5.7 million, which represents an effective income tax rate of 31.0%, for the six months ended March 31, 2013, compared to expense of $14.7 million and an effective income tax rate of 38.7%, for the six months ended March 31, 2012.

The effective tax rate for fiscal 2013 was favorably impacted by an estimated 2012 research and development tax credit which was retroactively reinstated by legislation passed in January 2013. The effective tax rate for fiscal 2012 was unfavorably impacted by $4.6 million of non-deductible transaction expenses, which resulted in $1.8 million of incremental tax expense, incurred to effect our separation from Ralcorp and $0.7 million of tax expense related to an uncertain tax position we expect to take on our 2012 short-period tax return.

Liquidity and Capital Resources

Historically, we have generated and expect to continue to generate positive cash flows from operations, supported by favorable operating income margins. We believe our cash on hand, cash flows from operations and our current and future credit facilities will be sufficient to satisfy our future working capital, research and development activities, capital expenditures, pension contributions and other financing requirements for the foreseeable future. Our ability to generate positive cash flows from operations is dependent on general economic conditions, competitive pressures and other business and risk factors. If we are unable to generate sufficient cash flows from operations, or otherwise to comply with the terms of our credit facilities, we may be required to seek additional financing alternatives. There can be no assurance that we would be able to obtain additional financing on terms acceptable to us or at all.

Short-term financing needs primarily consist of working capital requirements interest payments on our senior notes and dividend payments on our recently issued cumulative preferred stock. Long-term financing needs will depend largely on potential growth opportunities, including acquisition activity.

The following tables show recent cash flow data, which is discussed below (dollars in millions).

	Six months ended March 31,
	2013			2012
Cash provided by operating activities	$	18.6		$	77.1
Cash used by investing activities	(20.2		)	(15.8		)
Cash provided by financing activities	309.1			0.7
Effect of exchange rate changes on cash	(0.3		)	0.4
Net increase in cash and cash equivalents	$	307.2		$	62.4

Cash provided by operating activities for the six months ended March 31, 2013 decreased $58.5 million compared to the prior year period. The decrease includes incremental cash of $15.0 million provided by the premium received on the issuance of our senior notes. After reducing current year operating cash flows for this item, the decrease from the prior year period was $73.5 million. This decrease was primarily driven by $49.7 million of unfavorable working capital changes during the six months ended March 31, 2013 when compared to working capital changes in fiscal 2012, primarily driven by increased inventory levels related to production of new products and new package sizes for existing products. Additionally, we made interest payments totaling $39.8 million in fiscal 2013. In fiscal 2012, prior to our spin-off from Ralcorp, we were not required to cash settle interest expense.

25

Cash used in investing activities for the six months ended March 31, 2013 increased $4.4 million compared to the prior year period. The increase was driven primarily by a business acquisition for $9.2 million. This increase was partially offset by lower capital expenditures in the current year. The prior year capital expenditures included the purchase of our corporate office building and related furniture and fixtures.

Cash provided by financing activities was $309.1 million for the six months ended March 31, 2013 compared to $0.7 million in the prior year period. The increase is primarily driven by the proceeds from issuance of additional debt of $250.0 million and the net proceeds from the issuance of preferred stock of $234.1 million partially offset by payment of related debt issuance costs and the $170.6 million principal repayment on our term loan during the six months ended March 31, 2013.

Debt Covenants

Under the terms of our senior secured credit facility, as amended, we are required to comply with certain financial covenants consisting of ratios for maximum consolidated leverage and minimum interest expense coverage. As of March 31, 2013, we were in compliance with all such financial covenants.

Critical Accounting Policies and Estimates

The following discussion is presented pursuant to the United States Securities and Exchange Commission’s Financial Reporting Release No. 60, “Cautionary Advice Regarding Disclosure About Critical Accounting Policies.” The policies below are both important to the representation of Post’s financial condition and results and require management’s most difficult, subjective or complex judgments.

Under generally accepted accounting principles in the United States, we make estimates and assumptions that impact the reported amounts of assets, liabilities, revenues, and expenses as well as the disclosure of contingent liabilities. We base estimates on past experience and on various other assumptions that are believed to be reasonable under the circumstances. Those estimates form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Our critical accounting policies and estimates are more fully described in our Annual Report on Form 10-K for the year ended September 30, 2012 as filed with the SEC on December 13, 2012. There have been no significant changes to our critical accounting policies and estimates since September 30, 2012. As discussed in greater detail in our Annual Report on Form 10-K for the year ended September 30, 2012, we incurred impairment losses related to goodwill and certain of our indefinite lived trademarks during fiscal years 2011 and 2010. While we incurred no impairment losses during fiscal 2012, the estimated fair values for two of our trademarks only slightly exceeded their respective carrying values as of September 30, 2012. During the six months ended 2013 there have been no changes in our long-term expectations for these trademarks, however, we will continue to monitor our actual performance against our long-range estimates. Future unfavorable changes in our assumptions affecting the valuation of these trademarks would likely result in an impairment, which could be material to our financial statements.

Recently Issued Accounting Standards

See Note 2 of “Notes to Condensed Consolidated Financial Statements” for a discussion regarding recently issued accounting standards.

ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

As of March 31, 2013, we have indebtedness in the form of secured notes with a principal value of $1,025.0 million (the “Notes”) and our senior secured credit facility, as amended, (the “Credit Facility”) which consists of an unfunded revolving credit facility with $173.9 million of available capacity after consideration of $1.1 million of letters of credit outstanding.

The Notes bear fixed rate interest of 7.375% per annum. Interest payments on the Notes are due semi-annually each February 15 and August 15. The maturity date of the Notes is February 15, 2022.

Borrowings under the Credit Facility bear interest at LIBOR or a base rate (as defined in the Credit Facility) plus an applicable margin ranging from 1.50% to 2.00% for LIBOR-based loans and from 0.50% to 1.00% for Base Rate-based loans, depending upon the Company's consolidated leverage ratio. Accordingly, borrowings under the Credit Facility are subject to an element of market risk from changes in interest rates.

There have been no material changes in our assessment of market risk sensitivity since our presentation of “Quantitative and Qualitative Disclosures About Market Risk,” in our Annual Report on Form 10-K, as filed with the SEC on December 13, 2012.

26

ITEM 4.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of the Chief Executive Officer and Chief Financial Officer of the Company, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, our CEO and CFO concluded that, as of the end of the period covered by this report, the Company's disclosure controls and procedures were effective to provide reasonable assurance of achieving the desired control objectives.

Changes in Internal Control Over Financial Reporting

There have not been any changes in the Company’s internal control over financial reporting that occurred during the Company’s fiscal quarter ended March 31, 2013 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

We are subject to various legal proceedings and actions arising in the normal course of our business. While the results of all such proceedings and actions cannot be predicted, management believes, based on facts known to management today, that the ultimate outcome of all such proceedings and actions will not have a material adverse affect on our consolidated financial position, results of operation, or cash flows.

ITEM 1A. RISK FACTORS.

There have been no material changes to the risk factors we previously disclosed in our Annual Report on Form 10-K, filed with the SEC on December 13, 2012, as of and for the year ended September 30, 2012.

Recently Issued Accounting Standards

Recently Issued Accounting Standards

On January 31, 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-01, "Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities," which provides scope clarifications related to the previously issued ASU 2011- 11. These ASU's provide new requirements for disclosures about instruments and transactions eligible for offset in the statement of financial position, as well as instruments and transactions subject to an agreement similar to a master netting arrangement. The amendments in these updates are effective for annual reporting periods beginning on or after January 1, 2013 (i.e., Post's financial statements for the year ending September 30, 2014), and interim periods within those annual periods. The adoption of this update is not expected to have a material effect on Post's financial position, results of operations or cash flows.

On February 5, 2013, the FASB issued ASU 2013-02, "Reporting Amounts Reclassified out of Accumulated Other Comprehensive Income," which requires additional disclosure of amounts recorded in Accumulated Other Comprehensive Income and amounts that are reclassified from Accumulated Other Comprehensive Income. This update is effective for fiscal years beginning after December 15, 2012 (i.e., Post's financial statements for the year ending September 30, 2014), and interim periods within those annual periods. The adoption of this update is not expected to have a material effect on Post's financial position, results of operations or cash flows.

Schedule Of Condensed Financial Statements [Abstract]

Guarantor Financials

Condensed Financial Statements of Guarantors

The Company issued the Notes in an aggregate principal amount of $1,025.0. The Notes were issued pursuant to an indenture dated as of February 3, 2012 among the Company, Post Foods, LLC, as guarantor, and Wells Fargo Bank, National Association, as trustee.

The Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by each of our existing and future domestic subsidiaries, the “Guarantors.” Our foreign subsidiaries, the “Non-Guarantors,” will not guarantee the 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 Post Holdings, Inc., the “Parent Company”, 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 Foods, LLC, currently the Company's sole domestic subsidiary, is a disregarded entity for U.S. income tax purposes, therefore income tax expense has been presented on the Guarantors' Condensed Statements of Operations using the U.S. effective tax rate for the Company. Income tax payable and deferred tax items for the consolidated U.S. tax paying group reside solely on the Parent Company's Condensed Balance Sheet. For periods prior to February 3, 2012, the Parent Company had no operations and therefore no Parent Company financial information is presented for those periods and accordingly the equity earnings of the Parent Company will not equal the earnings of the subsidiaries.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Background

Background

Post Holdings, Inc. (“Post” or the “Company”) is a manufacturer, marketer and distributor of branded ready-to-eat cereals in the United States and Canada. Post’s products are generally sold to supermarket chains, wholesalers, supercenters, club stores, mass merchandisers, distributors, convenience stores and the foodservice channel in North America. The Company's products are primarily manufactured at four facilities located in Battle Creek, Michigan; Jonesboro, Arkansas; Modesto, California; and Niagara Falls, Ontario.

On February 3, 2012, Post completed its legal separation via a tax free spin-off (the “Spin-Off”) from Ralcorp Holdings, Inc., which was acquired by ConAgra Foods, Inc. on January 29, 2013 (“Ralcorp”) . On February 6, 2012, Post began regular trading on the New York Stock Exchange under the ticker symbol “POST” as an independent, public company.

Post has a single operating segment and manufactures and markets products under several brand names, including Honey Bunches of Oats^®, Pebbles™, Post Selects^®, Great Grains^®, Spoon Size^® Shredded Wheat, Post^® Raisin Bran, Grape-Nuts^® and Honeycomb^®. With the acquisition of substantially all of the assets of Attune Foods, Inc. on December 31, 2012 (see Note 3), Post's portfolio of brands now also includes Attune^®, Uncle Sam^® and Erewhon^®.

Unless otherwise stated or the context otherwise indicates, all references in this Form 10-Q to “Post,” “the Company,” “us,” “our” or “we” mean Post Holdings, Inc. and its consolidated subsidiaries, and for periods prior to the Spin-Off from Ralcorp, the Branded Cereal Business of Ralcorp.

Basis of Presentation

These unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”), under the rules and regulations of the United States Securities and Exchange Commission (the “SEC”), and on a basis substantially consistent with the audited consolidated financial statements of the Company as of and for the fiscal year ended September 30, 2012. These unaudited condensed consolidated financial statements should be read in conjunction with such audited consolidated financial statements, which are included in the Company’s Annual Report on Form 10-K filed with the SEC on December 13, 2012.

These unaudited condensed consolidated financial statements include all adjustments (consisting of normal recurring adjustments and accruals) that management considers necessary for a fair statement of its financial position, results of operations, comprehensive income and cash flows for the interim periods presented. Interim results are not necessarily indicative of the results for any other interim period or for the entire fiscal year.

Prior to the Spin-Off, Post's operations consisted of the Branded Cereals Business of Ralcorp. As such, the financial information prior to the Spin-Off may not necessarily reflect Post's financial position, results of operations, comprehensive income and cash flows had Post been an independent, publicly-traded company for the entirety of the three and six months ended March 31, 2012, as presented herein.

For periods prior to the Spin-Off, these unaudited condensed consolidated financial statements include allocations of certain Ralcorp corporate expenses. Management believes the assumptions and methodologies underlying the allocation of general corporate overhead expenses are reasonable. However, such expenses may not be indicative of the actual level of expense that would have been incurred by Post if it had operated as an independent, publicly-traded company. These allocated expenses relate to various services that were provided to Post by Ralcorp, including, but not limited to, cash management and other treasury services, administrative services (such as tax, employee benefit administration, risk management, internal audit, accounting and human resources) and stock-based compensation plan administration. See Note 15 for further information on services that Ralcorp continues to provide to the Company.

The financial position and operating results of foreign operations are consolidated using the local currency as the functional currency. Local currency assets and liabilities are translated at the rates of exchange on the balance sheet date, and local currency revenues and expenses are translated at average rates of exchange during the period. Resulting translation gains or losses are included in the condensed consolidated balance sheet as a component of accumulated other comprehensive loss.

Use of Estimates

The preparation of the financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported in the condensed consolidated financial statements and footnotes thereto. Actual results could differ from those estimates. Significant estimates inherent in the preparation of the condensed consolidated financial statements include accounting for reserves established for doubtful accounts, stock-based compensation, impairment analyses, depreciation and amortization, income taxes, litigation matters and contingencies.

Revision

In the preparation of the financial statements for the year ended September 30, 2012, the Company identified errors within the statements of cash flows for the six months ended March 31, 2012. The Company concluded the errors were not material to the previously reported interim financial statements. Accordingly, the Company has revised its 2012 comparative statements of cash flows included herein. The revisions are required to correct errors in the calculation of adjustments to the statements of cash flows that related to the Company's separation from Ralcorp on February 3, 2012. The impact of the revision was to increase net cash flows from operations and decrease net cash flows from financing activities by $10.0. The six month net cash flow from operations changed from $67.1 to $77.1.  The net cash flow from financing activities for the six months changed from $10.7 to $0.7. The errors did not impact the consolidated statements of operations and comprehensive income/(loss) for the three and six months ended March 31, 2012.

The preferred stock has no maturity date; however, holders of the preferred stock may convert their preferred 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. Additionally, on or after February 15, 2018, the Company will have the option to redeem some or all the preferred stock at a redemption price equal to 100% of the liquidation preference per share, plus accrued and unpaid dividends if the closing sale price of the Company's common stock has been at least 130% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period.

Earnings Per Share [Abstract]

Earnings per Share

Note 6 – Earnings per Share

Basic earnings per share is based on the average number of common shares outstanding during the period. Diluted earnings per share is based on the average number of shares used for the basic earnings per share calculation, adjusted for the dilutive effect of stock options, stock appreciation rights and restricted stock equivalents using the "treasury stock" method. The impact of potentially dilutive convertible preferred stock is calculated using the "if-converted" method. For the three and six months ended March 31, 2012, the computation of basic and diluted earnings per common share is calculated assuming the number of shares of Post common stock outstanding on February 3, 2012 had been outstanding at the beginning of the period.

The following table sets forth the computation of basic and diluted earnings per share for the three and six months ended March 31, 2013 and 2012, respectively.

	Three months ended March 31,					Six months ended March 31,

Diluted earnings per common share	$	0.13		$	0.30	$	0.36		$	0.68

For the three and six months ended March 31, 2013, weighted-average shares for diluted earnings per common share excludes 0.6 million and 2.2 million equity awards, respectively and 5.1 million shares related to the potential conversion of the Company's convertible preferred stock, see Note 11, for both the three and six months ended March 31, 2013 as they were anti-dilutive.

Derivative financial instruments and hedging

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 debt, and foreign currency exchange rate risks relating to its foreign subsidiary. 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.

Prior to the Spin-Off, Post participated in Ralcorp's derivative instrument program which consisted of commodity contracts (options, futures, and swaps) on raw material and fuel purchases. Prior to the Spin-Off date, Post no longer participated in the Ralcorp derivative instrument program. Derivative instrument gains and losses are included in “cost of goods sold” for all periods presented.

The Company maintains options and futures contracts which have been designated as economic hedges of raw materials and fuel purchases. The following table presents the balance sheet location and fair value of the Company's derivative instruments.

Fair Value Disclosures [Abstract]

Fair value measurements

Fair Value Measurements

The following table represents Post's assets and liabilities measured at fair value on a recurring basis and the basis for that measurement according to the levels in the fair value hierarchy in ASC Topic 820:

	March 31, 2013						September 30, 2012
	Total		Level 1		Level 2		Total		Level 1		Level 2
Deferred compensation investment	$	7.6	$	7.6	$	—	$	1.4	$	1.4	$	—
Derivative instruments	0.4		—		0.4		1.6		—		1.6
Deferred compensation liabilities	12.4		—		12.4		8.6		—		8.6

The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity's pricing based upon their own market assumptions. The fair value hierarchy consists of three levels: 

Level 1 — Inputs are quoted prices in active markets for identical assets or liabilities.

Level 2 — Inputs are quoted prices of similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable and market-corroborated inputs which are derived principally from or corroborated by observable market data.

Level 3 — Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

The deferred compensation investment is invested primarily in mutual funds and is measured using the market approach. This investment is in the same funds and purchased in substantially the same amounts as the participants' selected investment options (excluding Post and Ralcorp 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.

Changes in the fair value of assets and liabilities measured at fair value on a recurring basis are recorded as a component of selling, general and administrative expense, except for derivative instruments which are recorded in cost of goods sold.

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 of these financial instruments. The fair value of long-term debt as of March 31, 2013 (see Note 12) is approximately$1,121.1 based on quoted market prices for the Company's senior notes.

Transactions with Former Owner

Prior to the Spin-Off, Post operated under Ralcorp's centralized cash management system, Post's cash requirements were provided directly by Ralcorp, and cash generated by Post was generally remitted directly to Ralcorp. Transaction systems (e.g. payroll, employee benefits and accounts payable) used to record and account for cash disbursements were generally provided by Ralcorp. Ralcorp also provided centralized demand planning, order management, billing, credit and collection services to Post. Transaction systems (e.g. revenues, accounts receivable and cash application) used to record and account for cash receipts were generally provided by centralized Ralcorp organizations. These Ralcorp systems were generally designed to track assets/liabilities and receipts/payments on a business specific basis. After the Spin-Off, Ralcorp continues to provide certain of these services to Post under a transition services agreement (“TSA”) between the companies.

For periods prior to the Spin-Off, costs and expenses in the accompanying condensed consolidated statements of operations represent direct and allocated costs and expenses related to Post. Costs for certain functions and services performed by centralized Ralcorp organizations were allocated to Post based upon reasonable activity bases (generally volume, revenues, net assets or a combination as compared to the total of Ralcorp and Post amounts) or other reasonable methods. The condensed consolidated statements of operations include expense allocations for certain manufacturing, shipping, distribution and administration costs including information systems, procurement, accounting shared services, legal, tax, human resources, payroll, credit and accounts receivable, customer service and cash management. For the three and six months ended March 31, 2012, total allocated costs were $0.8 and $4.6, respectively, which were reported in “selling, general and administrative expenses.” After the Spin-Off, costs for services provided by Ralcorp are based on agreed upon fees contained in the TSA. TSA charges were $1.5, $2.2, $3.1, and $2.2 for the three and six months ended March 31, 2013 and 2012, respectively, and were reported in “selling, general and administrative expenses.”

Post produces certain products for sale to Ralcorp. For periods prior to the Spin-Off, the amounts related to these transactions have been included in the accompanying financial statements based upon transfer prices in effect at the time of the individual transactions which were consistent with prices of similar arm's-length transactions. For periods subsequent to the Spin-Off, these transactions were based upon pricing governed by the TSA with Ralcorp. Net sales related to those transactions was $3.5, $3.4, $7.5 and $8.4 in the three and six months ended March 31, 2013 and 2012, respectively.

In connection with the Spin-Off, the Company entered into a series of agreements with Ralcorp which are intended to govern the relationship between the Company and Ralcorp and to facilitate an orderly separation of the Company from Ralcorp. These agreements include a Separation and Distribution Agreement, Tax Allocation Agreement and the TSA, among others. Additionally, the Company has agreed to indemnify Ralcorp for income taxes incurred if the Company violates certain provisions of the IRS private letter ruling obtained by Ralcorp. Under certain of these agreements, the Company will incur expenses payable to Ralcorp in connection with certain administrative services provided for varying lengths of time. The Company incurred separation related costs of $2.4, $5.3, $5.2 and $8.0 during the three and six months ended March 31, 2013 and 2012, respectively. The costs incurred were primarily related to professional service fees to effect the Spin-Off and professional service fees and duplicative costs incurred by Post to establish stand-alone processes and systems for activities performed by Ralcorp under the TSA. These costs were reported as a component of “Selling, general and administrative expenses.” See Note 1 for additional information on the Spin-Off. As of March 31, 2013, the Company has a $3.7 net receivable related to the net transactions from these agreements.
