	Basis of Presentation and Revisions

	The unaudited Consolidated Balance Sheets as of February 28, 2014 and 2013, the Consolidated Statements of Operations for the the three and six months ended February 28, 2014 and 2013, the Consolidated Statements of Comprehensive Income for the three and six months ended February 28, 2014 and 2013, and the Consolidated Statements of Cash Flows for the six months ended February 28, 2014 and 2013, reflect in the opinion of our management, all normal recurring adjustments necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented. The results of operations and cash flows for interim periods are not necessarily indicative of results for a full fiscal year because of, among other things, the seasonal nature of our businesses. Our Consolidated Balance Sheet data as of August 31, 2013, has been derived from our audited consolidated financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (GAAP).

	The consolidated financial statements include our accounts and the accounts of our wholly-owned and majority-owned subsidiaries and limited liability companies, which is primarily National Cooperative Refinery Association (NCRA), included in our Energy segment. The effects of all significant intercompany accounts and transactions have been eliminated.

	These statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended August 31, 2013, included in our Annual Report on Form 10-K, filed with the Securities and Exchange Commission.

	We previously reported certain derivative assets and liabilities on a net basis on our Consolidated Balance Sheets. In connection with the issuance of our August 31, 2013 financial statements, we determined that such derivatives should have been reported on a gross basis and have therefore revised our February 28, 2013 Consolidated Balance Sheet, which resulted in an increase in both derivative assets and derivative liabilities of $212.7 million. The Consolidated Statement of Cash Flows for the six months ended February 28, 2013, has also been revised for this change with no impact to net operating, investing or financing cash flows. We do not believe these revisions are material.

	In December 2011, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-11, “Disclosures about Offsetting Assets and Liabilities.” ASU No. 2011-11, and the subsequent amendments issued in ASU No. 2013-01, "Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities," create new disclosure requirements about the nature of an entity’s rights of setoff and related arrangements associated with certain financial instruments and recognized derivative instruments. The disclosure requirements in this update are effective for annual reporting periods, and interim periods within those years, beginning on or after January 1, 2013. The required disclosures have been included in Note 9, Derivative Financial Instruments and Hedging Activities.

	In February 2013, the FASB issued ASU No. 2013-02, "Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income." ASU No. 2013-02 requires an entity to provide information about the effects of significant reclassifications out of accumulated other comprehensive income, by component, either on the face of the financial statements or in the notes to the financial statements and is intended to help improve the transparency of changes in other comprehensive income. ASU No. 2013-02 does not amend any existing requirements for reporting net income or other comprehensive income in the financial statements. ASU No. 2013-02 became effective for our annual and interim reporting periods beginning in fiscal 2014. The required disclosures have been included in Note 6, Equities.

	Goodwill and Other Intangible Assets

	Goodwill was $104.6 million, $85.1 million and $88.1 million on February 28, 2014, August 31, 2013 and February 28, 2013, respectively, and is included in other assets on our Consolidated Balance Sheets. We acquired goodwill of $19.4 million during the six months ended February 28, 2014, which related primarily to acquisitions in our Ag segment for which we paid $97.9 million in cash consideration. These acquisitions were not material, individually or in aggregate, to our consolidated financial statements.

	Intangible assets subject to amortization primarily include customer lists, trademarks and agreements not to compete, and are amortized over their respective useful lives (ranging from 2 to 30 years). Excluding goodwill, the gross carrying amount of our intangible assets was $113.5 million, $81.5 million and $81.8 million on February 28, 2014, August 31, 2013 and February 28, 2013, respectively. Accumulated amortization was $46.7 million, $46.0 million and $40.5 million as of February 28, 2014, August 31, 2013 and February 28, 2013, respectively. Intangible assets acquired were $36.2 million and $1.4 million during the six months ended February 28, 2014 and 2013, respectively. Intangible assets acquired during the six months ended February 28, 2014, primarily relate to various acquisitions in our Ag segment. Total amortization expense for intangible assets during the six months ended February 28, 2014 and 2013, was $4.9 million and $5.0 million, respectively. The estimated annual amortization expense related to intangible assets subject to amortization for the next five years is as follows:



		(Dollars in thousands)
	Year 1	$	8,141

	Year 2	8,654

	Year 3	7,902

	Year 4	6,334

	Year 5	3,543

	Thereafter	31,407

	Total	$	65,981


	In our Energy segment, major maintenance activities (turnarounds) at our two refineries are accounted for under the deferral method. Turnarounds are the scheduled and required shutdowns of refinery processing units. The costs related to the significant overhaul and refurbishment activities include materials and direct labor costs. The costs of turnarounds are deferred when incurred and amortized on a straight-line basis over the period of time estimated to lapse until the next turnaround occurs, which is generally 2 to 4 years. The amortization expense related to turnaround costs is included in cost of goods sold in our Consolidated Statements of Operations. The selection of the deferral method, as opposed to expensing the turnaround costs when incurred, results in deferring recognition of the turnaround expenditures. The deferral method also results in the classification of the related cash outflows as investing activities in our Consolidated Statements of Cash Flows, whereas expensing these costs as incurred, would result in classifying the cash outflows as operating activities.

	Supplier Advance Payments

	Beginning November 30, 2013, supplier advance payments are reported as a separate line item on our Consolidated Balance Sheets. Prior period amounts have been reclassified accordingly. Supplier advance payments primarily include amounts paid for in-transit grain purchases from suppliers and amounts paid to crop nutrient suppliers to lock in future supply and pricing.

	Customer Advance Payments

	Customer advance payments primarily consist of amounts received from customers for in-transit grain shipments and amounts received from crop nutrients customers for future shipments.

	Recent Accounting Pronouncements

	In February 2013, the FASB issued ASU No. 2013-04, "Liabilities." ASU No. 2013-04 requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in this ASU also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We are currently evaluating the impact that the adoption will have on our consolidated financial statements in fiscal 2015.

	Total receivables	$	2,658,922	$	2,935,478	$	2,751,952


	Trade accounts receivable are initially recorded at a selling price, which approximates fair value, upon the sale of goods or services to customers. Subsequently, trade accounts receivable are carried at net realizable value, which includes an allowance for estimated uncollectible amounts. We calculate this allowance based on our history of write-offs, level of past due accounts, and our relationships with, and the economics status of, our customers.

	CHS Capital, LLC (CHS Capital), our wholly-owned subsidiary, has notes receivable from commercial borrowers and producer borrowings. The short-term notes receivable generally have terms of 12-14 months and are reported at their outstanding principle balances as CHS Capital has the ability and intent to hold these notes to maturity. The carrying value of CHS Capital notes receivable approximates fair value, given their short duration and the use of market pricing adjusted for risk.The notes receivable from commercial borrowers are collateralized by various combinations of mortgages, personal property, accounts and notes receivable, inventories and assignments of certain regional cooperative’s capital stock. These loans are primarily originated in the states of Minnesota, Wisconsin and North Dakota. CHS Capital also has loans receivable from producer borrowers which are collateralized by various combinations of growing crops, livestock, inventories, accounts receivable, personal property and supplemental mortgages. In addition to the short-term amounts included in the table above, CHS Capital had long-term notes receivable with durations of not more than 10 years of $160.2 million, $127.7 million and $120.2 million at February 28, 2014, August 31, 2013 and February 28, 2013, respectively. The long-term notes receivable are included in other assets on our Consolidated Balance Sheets. As of February 28, 2014, August 31, 2013 and February 28, 2013 the commercial notes represented 76%, 59% and 79%, respectively, and the producer notes represented 24%, 41% and 21%, respectively, of the total CHS Capital notes receivable.

	CHS Capital evaluates the collectability of both commercial and producer notes on a specific identification basis, based on the amount and quality of the collateral obtained, and records specific loan loss reserves when appropriate. A general reserve is also maintained based on historical loss experience and various qualitative factors. In total, our specific and general loan loss reserves related to CHS Capital are not material to our consolidated financial statements, nor are the historical write-offs. The accrual of interest income is discontinued at the time the loan is 90 days past due unless the credit is well-collateralized and in process of collection. The amount of CHS Capital notes that were past due was not material at any reporting date presented.

	CHS Capital has commitments to extend credit to a customer as long as there is no violation of any condition established in the contract. As of February 28, 2014, CHS Capital's customers have additional available credit of $943.7 million.

	Total inventories	$	3,381,737	$	2,664,735	$	3,626,673


	As of February 28, 2014, we valued approximately 14% of inventories, primarily related to Energy, using the lower of cost, determined on the LIFO method, or market (16% and 14% as of August 31, 2013 and February 28, 2013, respectively). If the FIFO method of accounting had been used, inventories would have been higher than the reported amount by $579.4 million, $652.6 million and $535.1 million at February 28, 2014, August 31, 2013 and February 28, 2013, respectively. An actual valuation of inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Interim LIFO calculations are based on management's estimates of expected year-end inventory levels and costs, and are subject to the final year-end LIFO inventory valuation.

	As of August 31, 2013, we owned 79.2% of NCRA. In fiscal 2012, we entered into an agreement to purchase the remaining shares of NCRA from Growmark Inc. and MFA Oil Company in separate closings to be held annually through fiscal 2016. Pursuant to this agreement, we made payments during the six months ended February 28, 2014 and 2013 of $66.0 million and $66.0 million respectively; increasing our ownership to 84.0%. The present value of the remaining payments is included as mandatorily redeemable noncontrolling interest on our consolidated balances sheets. In addition to these payments, we paid $16.5 million during the six months ended February 28, 2014 related to the associated crack spread contingent liability. The fair value of the remaining contingent liability was $140.6 million as of February 28, 2014.

	We have a 24% ownership in Horizon Milling, LLC and Horizon Milling G.P., flour milling joint ventures with Cargill Incorporated (Cargill), which are included in Corporate and Other. On March 4, 2013, we entered into a definitive agreement with Cargill and ConAgra Foods, Inc. to form Ardent Mills, a joint venture combining the North American flour milling operations of the three parent companies, including the Horizon Milling, LLC and Horizon Milling G.P. assets, with CHS holding a 12% interest. Upon closing, Ardent Mills is expected to be financed with funds from third-party borrowings, which would not require credit support from the owners. The borrowings are anticipated to be no less than $600 million with proceeds distributed to each owner in proportion to the ownership interests, adjusted for any deviations in specified working capital target amounts. The transaction is expected to close in fiscal 2014, subject to financing and certain other customary closing conditions. In connection with the closing, the parties will also enter into various ancillary and non-compete agreements including, among other things, an agreement for CHS to supply Ardent Mills with certain wheat and durum products.

	We have a 50% interest in Ventura Foods, LLC (Ventura Foods), a joint venture which produces and distributes primarily vegetable oil-based products, and is included in Corporate and Other. We account for Ventura Foods as an equity method investment, and as of February 28, 2014, our carrying value of Ventura Foods exceeded our share of their equity by $12.9 million, which represents equity method goodwill.

Amounts reclassified from accumulated other comprehensive income (loss) were related to pension and other postretirement benefits and cash flow hedges, and were recorded to net income. Pension and other postretirement reclassifications include amortization of net actuarial loss, prior service credit and transition amounts as disclosed in Note 7, Benefit Plans. In February 2014, interest rate swaps, which were previously accounted for as cash flow hedges, were terminated as the issuance of the underlying debt was no longer probable. As a result, a $13.5 million gain was reclassified from accumulated other comprehensive loss into net income. This pre-tax gain is included as a component of interest, net in the consolidated statements of operations for the three and six months ended February 28, 2014.

At this time, we do not anticipate having to make a contribution for our benefit plans in fiscal 2014.

	Segment Reporting

	We have aligned our segments based on an assessment of how our businesses are operated and the products and services they sell.

	Our Energy segment produces and provides primarily for the wholesale distribution of petroleum products and transportation of those products. Our Ag segment purchases and further processes or resells grains and oilseeds originated by our country operations business, by our member cooperatives and by third parties, and also serves as a wholesaler and retailer of crop inputs. Corporate and Other primarily represents the non-consolidated wheat milling and packaged food joint ventures, as well as our business solutions operations, which consist of commodities hedging, insurance and financial services related to crop production.

	Corporate administrative expenses are allocated to each business segment, and Corporate and Other, based on direct usage for services that can be tracked, such as information technology and legal, and other factors or considerations relevant to the costs incurred.

	Many of our business activities are highly seasonal and operating results will vary throughout the year. Historically, our income is generally lowest during the second fiscal quarter and highest during the third fiscal quarter. For example, in our Ag segment, agronomy and country operations businesses experience higher volumes and income during the spring planting season and in the fall, which corresponds to harvest. Also in our Ag segment, our grain marketing operations are subject to fluctuations in volumes and earnings based on producer harvests, world grain prices and demand. Our Energy segment generally experiences higher volumes and profitability in certain operating areas, such as refined products, in the summer and early fall when gasoline and diesel fuel usage is highest and is subject to global supply and demand forces. Other energy products, such as propane, may experience higher volumes and profitability during the winter heating and crop drying seasons.

	Our revenues, assets and cash flows can be significantly affected by global market prices for commodities such as petroleum products, natural gas, grains, oilseeds, crop nutrients and flour. Changes in market prices for commodities that we purchase without a corresponding change in the selling prices of those products can affect revenues and operating earnings. Commodity prices are affected by a wide range of factors beyond our control, including the weather, crop damage due to disease or insects, drought, the availability and adequacy of supply, government regulations and policies, world events, and general political and economic conditions.

	While our revenues and operating results are derived from businesses and operations which are wholly-owned and majority-owned, a portion of our business operations are conducted through companies in which we hold ownership interests of 50% or less and do not control the operations. We account for these investments primarily using the equity method of accounting, wherein we record our proportionate share of income or loss reported by the entity as equity income from investments, without consolidating the revenues and expenses of the entity in our Consolidated Statements of Operations. In our Ag segment, this principally includes our 50% ownership in TEMCO, LLC (TEMCO). In Corporate and Other, these investments principally include our 50% ownership in Ventura Foods and our 24% ownership in Horizon Milling, LLC and Horizon Milling G.P.

	Reconciling Amounts represent the elimination of revenues between segments. Such transactions are executed at market prices to more accurately evaluate the profitability of the individual business segments.

	Segment information for the three and six months ended February 28, 2014 and February 28, 2013 is as follows:

	Derivative Financial Instruments and Hedging Activities

	Our derivative instruments primarily consist of commodity and freight futures and forward contracts and, to a minor degree, may include foreign currency and interest rate swap contracts. These contracts are economic hedges of price risk, but are not designated or accounted for as hedging instruments for accounting purposes, with the exception of certain interest rate swap contracts which are accounted for as cash flow hedges. Derivative instruments are recorded on our Consolidated Balance Sheets at fair values as discussed in Note 10, Fair Value Measurements.

	Even though we have netting arrangements for our exchange-traded futures and options contracts and certain over-the-counter (OTC) contracts, we report our derivatives on a gross basis on our Consolidated Balance Sheets. Our associated margin deposits are also reported on a gross basis. Many of our derivative contracts with futures and options brokers require us to make both initial margin deposits of cash or other assets and subsequent deposits, depending on changes in commodity prices, in order to comply with applicable regulations. Our margin deposit assets are held by external brokers in segregated accounts and will be used to settle the associated derivative contracts on their specified settlement dates.

	As of February 28, 2014, August 31, 2013 and February 28, 2013, we had the following outstanding purchase and sales contracts:

In fiscal 2013, we entered into derivative contracts designated as cash flow hedging instruments that were terminated in February 2014 as the issuance of the underlying debt was no longer probable. As a result, a $13.5 million gain was reclassified from accumulated other comprehensive loss into net income. This pre-tax gain is included as a component of interest, net in the consolidated statements of operations for the three and six months ended February 28, 2014. As of February 28, 2014, August 31, 2013 and February 28, 2013, the unrealized gains deferred to accumulated other comprehensive loss were as follows:

	Fair Value Measurements

	The following table presents assets and liabilities, included in on our Consolidated Balance Sheets, that are recognized at fair value on a recurring basis, and indicates the fair value hierarchy utilized to determine such fair value. Assets and liabilities are classified, in their entirety, based on the lowest level of input that is a significant component of the fair value measurement. The lowest level of input is considered Level 3. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the classification of fair value assets and liabilities within the fair value hierarchy levels.

	Fair value measurements at February 28, 2014, August 31, 2013 and February 28, 2013 are as follows:

Readily marketable inventories — Our readily marketable inventories primarily include grain, oilseed, and minimally processed soy-based inventories that are stated at fair values. These commodities are readily marketable, have quoted market prices and may be sold without significant additional processing. We estimate the fair market values of these inventories included in Level 2 primarily based on exchange quoted prices, adjusted for differences in local markets. Changes in the fair market values of these inventories are recognized in our Consolidated Statements of Operations as a component of cost of goods sold.
Commodity, freight and foreign currency derivatives — Exchange traded futures and options contracts are valued based on unadjusted quoted prices in active markets and are classified within Level 1. Our forward commodity purchase and sales contracts, flat price or basis fixed derivative contracts, ocean freight contracts and other OTC derivatives are determined using inputs that are generally based on exchange traded prices and/or recent market bids and offers, adjusted for location specific inputs, and are classified within Level 2. The location specific inputs are generally broker or dealer quotations, or market transactions in either the listed or OTC markets. Changes in the fair values of these contracts are recognized in our Consolidated Statements of Operations as a component of cost of goods sold.
Other assets — Our available-for-sale investments in common stock of other companies, deferred compensation investments and Rabbi Trust assets are valued based on unadjusted quoted prices on active exchanges and are classified within Level 1. Changes in the fair values of these other assets are primarily recognized in our Consolidated Statements of Operations as a component of marketing, general and administrative expenses.
Interest rate swap derivatives — Fair values of our interest rate swap liabilities are determined utilizing valuation models that are widely accepted in the market to value such OTC derivative contracts. The specific terms of the contracts, as well as market observable inputs, such as interest rates and credit risk assumptions, are factored into the models. As all significant inputs are market observable, all interest rate swaps are classified within Level 2. Changes in the fair values of contracts not designated as hedging instruments for accounting purposes are recognized in our Consolidated Statements of Operations as a component of interest, net. Changes in the fair values of contracts designated as hedging instruments are deferred to accumulated other comprehensive loss in the equity section of our Consolidated Balance Sheets and are amortized into earnings within interest, net over the term of the agreements.
Accrued liability for contingent crack spread payment related to purchase of noncontrolling interests — The fair value of the accrued liability was calculated utilizing an average price option model, an adjusted Black-Scholes pricing model commonly used in the energy industry to value options. The model uses market observable inputs and unobservable inputs. Due to significant unobservable inputs used in the pricing model, the liability is classified within Level 3.

			Risk-free interest rate (d)	1.80-2.60% (2.23%)
			Expected life - years (e)	0.50-3.50 (2.12)
(a) Represents forward crack spread margin quotes and management estimates based on future settlement dates
(b) Represents the minimum contractual threshold that would require settlement with the counterparties
(c) Represents quarterly adjusted volatility estimates derived from daily historical market data
(d) Represents yield curves for U.S. Treasury securities
(e) Represents the range in the number of years remaining related to each contingent payment

Valuation processes for Level 3 measurements — Management is responsible for determining the fair value of our Level 3 financial instruments. Option pricing methods are utilized, as indicated above. Inputs used in the option pricing models are based on quotes obtained from third party vendors as well as management estimates for periods in which quotes cannot be obtained. Each reporting period, management reviews the unobservable inputs provided by third-party vendors for reasonableness utilizing relevant information available to us. Management also takes into consideration current and expected market trends and compares the liability’s fair value to hypothetical payments using known historical market data to assess reasonableness of the resulting fair value.
Sensitivity analysis of Level 3 measurements — The significant unobservable inputs that are susceptible to periodic fluctuations used in the fair value measurement of the accrued liability for contingent crack spread payments related to the purchase of noncontrolling interests are the adjusted forward crack spread margin and the expected volatility. Significant increases (decreases) in either of these inputs in isolation would result in a significantly higher (lower) fair value measurement. Although changes in the expected volatility are driven by fluctuations in the underlying crack spread margin, changes in expected volatility are not necessarily accompanied by a directionally similar change in the forward crack spread margin. Directional changes in the expected volatility can be affected by a multitude of factors including the magnitude of daily fluctuations in the underlying market data, market trends, timing of fluctuations, and other factors.

The discounted, aggregate amount of the minimum required payments under long-term unconditional purchase obligations, based on current exchange rates at February 28, 2014 is $437.9 million.

Guarantees

We are a guarantor for lines of credit and performance obligations of related companies. As of February 28, 2014, our bank covenants allowed maximum guarantees of $1.0 billion, of which $81.4 million was outstanding. We have collateral for a portion of these contingent obligations. We have not recorded a liability related to the contingent obligations as we do not expect to pay out any cash related to them, and the fair values are considered immaterial. The underlying loans to the counterparties for which we provide guarantees are current as of February 28, 2014.

Contingencies

In May 2013, we initiated a voluntary recall of certain soy protein products produced at our Ashdod, Israel facility following one customer's report to us of a positive test result for salmonella in product purchased from us. We notified applicable food safety regulators, including the Israel Ministry of Health and the U.S. Food and Drug Administration, of both the positive test result and our determination to conduct a voluntary recall. We have received no reports of salmonella-related illness in relation to the recalled products. We estimate our range of loss associated with this recall to be between $13.5 million and $27.0 million. During the year ended August 31, 2013, we recorded a reserve of $25.0 million, which is the amount within the range that we believe is the best estimate given the claims experience so far. We maintain product liability and general liability insurance (which includes product liability coverage), which we believe will offset some related product liability expenses. However, as of February 28, 2014, no insurance recoveries have been recorded related to this incident.

	The consolidated financial statements include our accounts and the accounts of our wholly-owned and majority-owned subsidiaries and limited liability companies, which is primarily National Cooperative Refinery Association (NCRA), included in our Energy segment. The effects of all significant intercompany accounts and transactions have been eliminated.
Derivative Financial Instruments and Hedging Activities	'
	Even though we have netting arrangements for our exchange-traded futures and options contracts and certain over-the-counter (OTC) contracts, we report our derivatives on a gross basis on our Consolidated Balance Sheets. Our associated margin deposits are also reported on a gross basis. Many of our derivative contracts with futures and options brokers require us to make both initial margin deposits of cash or other assets and subsequent deposits, depending on changes in commodity prices, in order to comply with applicable regulations. Our margin deposit assets are held by external brokers in segregated accounts and will be used to settle the associated derivative contracts on their specified settlement dates.
Goodwill and Other Intangible Assets	'
	Goodwill and Other Intangible Assets

	Goodwill was $104.6 million, $85.1 million and $88.1 million on February 28, 2014, August 31, 2013 and February 28, 2013, respectively, and is included in other assets on our Consolidated Balance Sheets. We acquired goodwill of $19.4 million during the six months ended February 28, 2014, which related primarily to acquisitions in our Ag segment for which we paid $97.9 million in cash consideration. These acquisitions were not material, individually or in aggregate, to our consolidated financial statements.

	Intangible assets subject to amortization primarily include customer lists, trademarks and agreements not to compete, and are amortized over their respective useful lives (ranging from 2 to 30 years). Excluding goodwill, the gross carrying amount of our intangible assets was $113.5 million, $81.5 million and $81.8 million on February 28, 2014, August 31, 2013 and February 28, 2013, respectively. Accumulated amortization was $46.7 million, $46.0 million and $40.5 million as of February 28, 2014, August 31, 2013 and February 28, 2013, respectively. Intangible assets acquired were $36.2 million and $1.4 million during the six months ended February 28, 2014 and 2013, respectively. Intangible assets acquired during the six months ended February 28, 2014, primarily relate to various acquisitions in our Ag segment. Total amortization expense for intangible assets during the six months ended February 28, 2014 and 2013, was $4.9 million and $5.0 million, respectively. The estimated annual amortization expense related to intangible assets subject to amortization for the next five years is as follows:

	In our Energy segment, major maintenance activities (turnarounds) at our two refineries are accounted for under the deferral method. Turnarounds are the scheduled and required shutdowns of refinery processing units. The costs related to the significant overhaul and refurbishment activities include materials and direct labor costs. The costs of turnarounds are deferred when incurred and amortized on a straight-line basis over the period of time estimated to lapse until the next turnaround occurs, which is generally 2 to 4 years. The amortization expense related to turnaround costs is included in cost of goods sold in our Consolidated Statements of Operations. The selection of the deferral method, as opposed to expensing the turnaround costs when incurred, results in deferring recognition of the turnaround expenditures. The deferral method also results in the classification of the related cash outflows as investing activities in our Consolidated Statements of Cash Flows, whereas expensing these costs as incurred, would result in classifying the cash outflows as operating activities.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements

	In February 2013, the FASB issued ASU No. 2013-04, "Liabilities." ASU No. 2013-04 requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation within the scope of this guidance is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and any additional amount the reporting entity expects to pay on behalf of its co-obligors. The guidance in this ASU also requires an entity to disclose the nature and amount of the obligation as well as other information about those obligations. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. We are currently evaluating the impact that the adoption will have on our consolidated financial statements in fiscal 2015.

	Amounts reclassified from accumulated other comprehensive income (loss) were related to pension and other postretirement benefits and cash flow hedges, and were recorded to net income. Pension and other postretirement reclassifications include amortization of net actuarial loss, prior service credit and transition amounts as disclosed in Note 7, Benefit Plans. In February 2014, interest rate swaps, which were previously accounted for as cash flow hedges, were terminated as the issuance of the underlying debt was no longer probable. As a result, a $13.5 million gain was reclassified from accumulated other comprehensive loss into net income. This pre-tax gain is included as a component of interest, net in the consolidated statements of operations for the three and six months ended February 28, 2014.
