Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Aug. 31, 2016
Accounting Policies [Abstract] |
Basis of Presentation | The consolidated financial statements include the accounts of CHS and all of our wholly-owned and majority-owned subsidiaries and limited liability companies. The effects of all significant intercompany transactions have been eliminated. The notes to our consolidated financial statements make reference to our Energy, Ag, Nitrogen Production and Foods reportable segments, as well as our Corporate and Other category, which represents an aggregation of individually immaterial operating segments. The Nitrogen Production reportable segment resulted from our investment in CF Industries Nitrogen, LLC ("CF Nitrogen") in February 2016. The Foods segment resulted from our investment in Ventura Foods, LLC ("Ventura Foods") becoming a significant operating segment in fiscal 2016. See Note 11, Segment Reporting for more information.
Major Maintenance Activities | Major Maintenance Activities Within our Energy segment, major maintenance activities (“turnarounds”) are performed at our Laurel, Montana and McPherson, Kansas refineries regularly. Turnarounds are the planned and required shutdowns of refinery processing units, which include the replacement or overhaul of equipment that have experienced decreased efficiency in resource conversion. Because turnarounds are performed to extend the life, increase the capacity, and/or improve the safety or efficiency of refinery processing assets, we follow the deferral method of accounting for turnarounds. Expenditures for turnarounds are capitalized (deferred) when incurred and amortized on a straight-line basis over a period of 2 to 4 years, which is the estimated time lapse between turnarounds. Should the estimated period between turnarounds change, we may be required to amortize the remaining cost of the turnaround over a shorter period, which would result in higher depreciation and amortization costs. Capitalized turnaround costs are included in other assets (long-term) on our Consolidated Balance Sheets and amortization expense related to the capitalized 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. Repair, maintenance and related labor costs are expensed as incurred and are included in operating cash flows.
Cash Equivalents | Cash and Cash Equivalents Cash equivalents include short-term, highly liquid investments with original maturities of three months or less at the date of acquisition. The fair value of cash and cash equivalents approximates the carrying value because of the short maturity of the instruments.
Inventories | Inventories Grain, processed grain, oilseed, processed oilseed and other minimally processed soy-based inventories are stated at net realizable values which approximate market values. These inventories are considered to be agricultural commodity inventories that are readily convertible to cash because of their commodity characteristics, widely available markets and international pricing mechanisms. Agricultural commodity inventories have quoted market prices in active markets, may be sold without significant further processing and have predictable and insignificant disposal costs. Changes in the net realizable value of merchandisable agricultural commodities inventories are recognized in earnings as a component of cost of goods sold. All other inventories are stated at the lower of cost or market. Costs for inventories produced or modified by us through a manufacturing process include fixed and variable production and raw material costs, and in-bound freight costs for raw materials. Costs for inventories purchased for resale include the cost of products and freight incurred to place the products at our points of sale. The costs of certain energy inventories (wholesale refined products, crude oil and asphalt) are determined on the last-in, first-out ("LIFO") method; all other inventories of non-grain products purchased for resale are valued on the first-in, first-out ("FIFO") and average cost methods.
Derivatives, Policy | Derivative Financial Instruments and Hedging Activities We enter into various derivative instruments to manage our exposure to movements primarily associated with agricultural commodity prices and freight costs, and to a lesser degree, foreign currency exchange rates and interest rates. With the exception of certain interest rate swap contracts, which are accounted for as cash flow hedges or fair value hedges, our derivative instruments represent economic hedges of price risk for which hedge accounting under ASC Topic 815, Derivatives and Hedging, is not applied. Rather, the derivative instruments are recorded on our Consolidated Balance Sheets at fair value with changes in fair value being recorded directly to earnings, primarily within cost of goods sold in our Consolidated Statements of Operations. See Note 12, Derivative Financial Instruments and Hedging Activities and Note 13, Fair Value Measurements for additional information. Although we have certain netting arrangements for our exchange-traded futures and options contracts and certain over-the-counter ("OTC") contracts, we have elected to report our derivative instruments on a gross basis on our Consolidated Balance Sheets under ASC Topic 210-20, Balance Sheet - Offsetting. 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 we do not apply hedge accounting under ASC Topic 815, Derivatives and Hedging, except with respect to certain interest rate swap contracts which are accounted for as cash flow hedges or fair value hedges as described below. Derivative instruments are recorded on our Consolidated Balance Sheets at fair value as described in Note 13, Fair Value Measurements. The following tables present the gross fair values of derivative assets, derivative liabilities, and margin deposits (cash collateral) recorded on our Consolidated Balance Sheets along with the related amounts permitted to be offset in accordance with U.S. GAAP. We have elected not to offset derivative assets and liabilities when we have the right of offset under ASC Topic 210-20, Balance Sheet - Offsetting; or when the instruments are subject to master netting arrangements under ASC Topic 815-10-45, Derivatives and Hedging - Overall.

Derivatives Not Designated as Hedging Instruments The majority of our derivative instruments have not been designated as hedging instruments. The following table sets forth the pretax gains (losses) on derivatives not accounted for as hedging instruments that have been included in our Consolidated Statements of Operations for the years ended August 31, 2016, 2015, and 2014. We have revised the information that we have historically included in this table below to correct for errors in the previously disclosed amounts. Although such gains and losses have been and continue to be appropriately recorded in the Consolidated Statements of Operations, the previous disclosures did not accurately reflect the derivative gains and losses in each period. These revisions did not materially impact our consolidated financial statements.

Commodity and Freight Contracts: When we enter into a commodity purchase or sales commitment, we incur risks related to price changes and performance including delivery, quality, quantity and shipment period. In the event that market prices decrease, we are exposed to risk of loss in the market value of inventory and purchase contracts with a fixed or partially fixed price. Conversely, we are exposed to risk of loss on our fixed or partially fixed price sales contracts in the event that market prices increase. Our use of hedging reduces the exposure to price volatility by protecting against adverse short-term price movements, but it also limits the benefits of favorable short-term price movements. To reduce the price risk associated with fixed price commitments, we generally enter into commodity derivative contracts, to the extent practical, to achieve a net commodity position within the formal position limits we have established and deemed prudent for each commodity. These contracts are primarily transacted on regulated commodity futures exchanges but may also include over-the-counter derivative instruments when deemed appropriate. For commodities where there is no liquid derivative contract, risk is managed through the use of forward sales contracts, other pricing arrangements and, to some extent, futures contracts in highly correlated commodities. These contracts are economic hedges of price risk, but are not designated as hedging instruments for accounting purposes. The contracts are recorded on our Consolidated Balance Sheets at fair values based on quotes listed on regulated commodity exchanges or the market prices of the underlying products listed on the exchanges, except that fertilizer and propane contracts are accounted for as normal purchase and normal sales transactions. Unrealized gains and losses on these contracts are recognized in cost of goods sold in our Consolidated Statements of Operations. When a futures position is established, initial margin must be deposited with the applicable exchange or broker. The amount of margin required varies by commodity and is set by the applicable exchange at its sole discretion. If the market price relative to a short futures position increases, an additional margin deposit would be required. Similarly, a margin deposit would be required if the market price relative to a long futures position decreases. Conversely, if the market price increases relative to a long futures position or decreases relative to a short futures position, margin deposits may be returned by the applicable exchange or broker. Our policy is to manage our commodity price risk exposure according to internal polices and in alignment with our tolerance for risk. Our profitability from operations is primarily derived from margins on products sold and grain merchandised, not from hedging transactions. At any one time, inventory and purchase contracts for delivery to us may be substantial. We have risk management policies and procedures that include established net position limits. These limits are defined for each commodity and business unit, and may include both trader and management limits as appropriate. The limits policy is overseen at a high level by our corporate compliance team, with day to day monitoring procedures managed within each individual business unit to ensure any limits overage is explained and exposures reduced or a temporary limit increase is established if needed. The position limits are reviewed, at least annually, with senior leadership and the Board of Directors. We monitor current market conditions and may expand or reduce our net position limits or procedures in response to changes in those conditions. In addition, all purchase and sales contracts are subject to credit approvals and appropriate terms and conditions. The use of hedging instruments does not protect against nonperformance by counterparties to cash contracts. We evaluate counterparty exposure by reviewing contracts and adjusting the values to reflect potential nonperformance. Risk of nonperformance by counterparties includes the inability to perform because of a counterparty’s financial condition and the risk that the counterparty will refuse to perform on a contract during periods of price fluctuations where contract prices are significantly different than the current market prices. We manage these risks by entering into fixed price purchase and sales contracts with preapproved producers and by establishing appropriate limits for individual suppliers. Fixed price contracts are entered into with customers of acceptable creditworthiness, as internally evaluated. Regarding our use of derivatives, we primarily transact in exchange traded instruments or enter into over-the-counter derivatives that clear through a designated clearing organization, which limits our counterparty exposure relative to hedging activities. Historically, we have not experienced significant events of nonperformance on open contracts. Accordingly, we only adjust the estimated fair values of specifically identified contracts for nonperformance. Although we have established policies and procedures, we make no assurances that historical nonperformance experience will carry forward to future periods. As of August 31, 2016 and 2015, we had outstanding commodity futures, options and freight contracts that were used as economic hedges, as well as fixed-price forward contracts related to physical purchases and sales of commodities. The table below presents the notional volumes for all outstanding commodity and freight contracts accounted for as derivative instruments.

Foreign Exchange Contracts: We conduct a substantial portion of our business in U.S. dollars, but we are exposed to immaterial risks relating to foreign currency fluctuations primarily due to grain marketing transactions in South America and Europe, and purchases of products from Canada. We use foreign currency derivative instruments to mitigate the impact of exchange rate fluctuations. Although our overall risk relating to foreign currency transactions is not significant, exchange rate fluctuations do, however, impact the ability of foreign buyers to purchase U.S. agricultural products and the competitiveness of U.S. agricultural products compared to the same products offered by alternative sources of world supply. The notional amounts of our foreign exchange derivative contracts were $802.2 million and $1.3 billion as of August 31, 2016 and August 31, 2015, respectively. Derivatives Designated as Cash Flow or Fair Value Hedging Strategies As of August 31, 2016 and 2015, we have certain derivatives designated as cash flow and fair value hedges. Interest Rate Contracts: We have outstanding interest rate swaps with an aggregate notional amount of $420.0 million designated as fair value hedges of portions of our fixed-rate debt. Our objective in entering into these transactions is to offset changes in the fair value of the debt associated with the risk of variability in the 3-month U.S. dollar LIBOR interest rate, in essence converting the fixed-rate debt to variable-rate debt. Offsetting changes in the fair values of both the swap instruments and the hedged debt are recorded contemporaneously each period and only create an impact to earnings to the extent that the hedge is ineffective. During the years ended August 31, 2016 and 2015, we recorded offsetting fair value adjustments of $9.8 million and $8.0 million, respectively, with no ineffectiveness recorded in earnings. In fiscal 2015, we entered into forward-starting interest rate swaps with an aggregate notional amount of $300.0 million designated as cash flow hedges of the expected variability of future interest payments on our anticipated issuance of fixed-rate debt. During the first quarter of fiscal 2016, we determined that certain of the anticipated debt issuances would be delayed; and we consequently recorded an immaterial amount of losses on the ineffective portion of the related swaps in earnings. Additionally, we paid $6.4 million in cash to settle two of the interest rate swaps upon their scheduled termination dates. During the second quarter of fiscal 2016, we settled an additional two interest rate swaps, paying $5.3 million in cash upon their scheduled termination. In January 2016, we issued the fixed-rate debt associated with these swaps and will amortize the amounts which were previously deferred to other comprehensive income into earnings over the life of the debt. The amounts to be included in earnings are not expected to be material during any 12-month period. During the third quarter of fiscal 2016, we settled the remaining two interest rate swaps, paying $5.1 million in cash upon their scheduled termination. We did not issue additional fixed-rate debt as previously planned, and we reclassified all amounts previously recorded to other comprehensive income into earnings. 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 expense, net in our Consolidated Statement of Operations for the year ended August 31, 2014. The following table presents the pretax gains (losses) recorded in other comprehensive income relating to cash flow hedges for the years ended August 31, 2016, 2015, and 2014:

Margin Deposits | Margin Deposits Many of our derivative contracts with futures and options brokers require us to make margin deposits of cash or other assets. Subsequent margin deposits may also be necessary when changes in commodity prices result in a loss on the contract value, in order to comply with applicable regulations. Our margin deposit assets are held by external brokers in segregated accounts to support the associated derivative contracts and may be used to fund or partially fund the settlement of those contracts as they expire. Similar to our derivative financial instruments, margin deposits are also reported on a gross basis.
Investments | Investments The equity method of accounting is used for joint ventures and other investments in which we are able to exercise significant influence over the entity’s operations, but do not have a controlling interest in the entity. Various factors are considered when assessing significant influence, including our ownership interest, representation on the Board of Directors, voting rights, and the impact of commercial arrangements that may exist with the entity. The cost method of accounting is used for other investments in which we do not exercise significant influence. Investments in other cooperatives are stated at cost, plus patronage dividends received in the form of capital stock and other equities. Patronage dividends are recorded as a reduction to cost of goods sold at the time qualified written notices of allocation are received. Investments in other debt and equity securities are classified as available-for-sale financial instruments and are stated at fair value, with unrealized gains and losses included as a component of accumulated other comprehensive loss on our Consolidated Balance Sheets. Investments in debt and equity instruments are carried at amounts that approximate fair values.
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided on the straight-line method by charges to operations at rates based upon the expected useful lives of individual or groups of assets (15 to 20 years for land improvements; 20 to 40 years for buildings; 5 to 20 years for machinery and equipment; and 3 to 10 years for office and other). The cost and related accumulated depreciation and amortization of assets sold or otherwise disposed of are removed from the related accounts and resulting gains or losses are reflected in operations. Expenditures for maintenance and minor repairs and renewals are expensed, while the costs for major maintenance activities are capitalized and amortized on a straight-line basis over the period of time estimated to lapse until the next major maintenance activity occurs. We also capitalize and amortize eligible costs to acquire or develop internal-use software that are incurred during the application development stage. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation and amortization are removed from the related accounts and resulting gains or losses are reflected in operations. Property, plant and equipment and other long-lived assets are reviewed for impairment when events or changes in circumstances indicate that the carrying amounts may not be recoverable. This evaluation of recoverability is based on various indicators, including the nature, future economic benefits and geographic locations of the assets, historical or future profitability measures, and other external market conditions. If these indicators suggest that the carrying amounts of an asset or asset group may not be recoverable, potential impairment is evaluated using undiscounted estimated future cash flows. Should the sum of the expected future net cash flows be less than the carrying value, an impairment loss would be recognized. An impairment loss would be measured by the amount by which the carrying value of the asset or asset group exceeds its fair value. We have asset retirement obligations with respect to certain of our refineries and other assets due to various legal obligations to clean and/or dispose of the component parts at the time they are retired. In most cases, these assets can be used for extended and indeterminate periods of time, as long as they are properly maintained and/or upgraded. It is our practice and current intent to maintain refineries and related assets and to continue making improvements to those assets based on technological advances. As a result, we believe our refineries and related assets have indeterminate lives for purposes of estimating asset retirement obligations because dates or ranges of dates upon which we would retire a refinery and related assets cannot reasonably be estimated at this time. When a date or range of dates can reasonably be estimated for the retirement of any component part of a refinery or other asset, we will estimate the cost of performing the retirement activities and record a liability for the fair value of that future cost. We have other assets that we may be obligated to dismantle at the end of corresponding lease terms subject to lessor discretion for which we have recorded asset retirement obligations. Based on our estimates of the timing, cost and probability of removal, these obligations are not material.
Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets Goodwill and other intangible assets are included in other assets (long-term) on our Consolidated Balance Sheets. Goodwill represents the excess of cost over the fair value of identifiable assets acquired. Goodwill is tested for impairment on an annual basis as of May 31, or more frequently if events or circumstances occur which could indicate impairment. Goodwill is tested for impairment at the reporting unit level, which has been determined to be our operating segments or one level below our operating segments in certain instances. Other intangible assets consist primarily of customer lists, trademarks and non-compete agreements. Intangible assets subject to amortization are expensed over their respective useful lives, which generally range from 2 to 30 years. We have no material intangible assets with indefinite useful lives. See Note 6, Other Assets for more information on goodwill and other intangible assets. We made acquisitions during the three years ended August 31, 2016, which were accounted for using the acquisition method of accounting. Operating results for these acquisitions were included in our consolidated financial statements beginning on the respective acquisition dates. The respective purchase prices were preliminarily allocated to the assets, liabilities and identifiable intangible assets acquired based upon the acquisition-date fair values. Any excess purchase price over the fair values of the acquired net assets acquired was recognized as goodwill. See Note 17, Acquisitions for more information on acquisition activity.
Revenue Recognition | Revenue Recognition We provide a wide variety of products and services, from agricultural inputs such as fuels, farm supplies and crop nutrients, to agricultural outputs that include grain and oilseed, processed grains and oilseeds and food products, and ethanol production and marketing. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability is reasonably assured. Grain and oilseed sales are recorded after the commodity has been delivered to its destination and final weights, grades and settlement prices have been agreed upon. All other sales are recognized upon transfer of title, which could occur either upon shipment to or receipt by the customer, depending upon the terms of the transaction. Shipping and handling amounts billed to a customer as part of a sales transaction are included in revenues and the related costs are included in cost of goods sold.
Environmental Expenditures | Environmental Expenditures We are subject to various federal, state, and local environmental laws and regulations. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Liabilities, including legal costs, related to remediation of contaminated properties are recognized when the related costs are considered probable and can be reasonably estimated. Estimates of environmental costs are based on current available facts, existing technology, undiscounted site-specific costs and currently enacted laws and regulations. Recoveries, if any, are recorded in the period in which recovery is received. Liabilities are monitored and adjusted as new facts or changes in law or technology occur.
Income Taxes | Income Taxes CHS is a nonexempt agricultural cooperative and files a consolidated federal income tax return with our 80% or more owned subsidiaries. We are subject to tax on income from nonpatronage sources, non-qualified patronage distributions and undistributed patronage-sourced income. Income tax expense is primarily the current tax payable for the period and the change during the period in certain deferred tax assets and liabilities. Deferred income taxes reflect the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for federal and state income tax purposes, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Due to the inherent uncertainty involved in making estimates, actual results could differ from those estimates.
Recent Accounting Pronouncements | Recent Accounting Pronouncements Adopted In November 2015, the FASB issued Accounting Standards Update ("ASU") No. 2015-17, Balance Sheet Classification of Deferred Taxes. ASU No. 2015-17 clarifies and simplifies the presentation of deferred income taxes by requiring deferred tax liabilities and assets to be classified as non-current in a classified statement of financial position. This ASU is effective for us beginning September 1, 2017, for our fiscal year 2018 and for interim periods within that fiscal year. Early adoption is permitted. We elected to early adopt ASU 2015-17 effective August 31, 2016 on a prospective basis. Adoption of ASU No. 2015-17 resulted in the netting of our current deferred tax assets against our non-current deferred tax assets in our Consolidated Balance Sheet as of August 31, 2016. Prior periods were not retrospectively adjusted. See Note 8, Income Taxes for more information on the adoption of ASU No. 2015-17. Not Yet Adopted In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU is intended to reduce existing diversity in practice in how certain cash receipts and payments are presented and classified in the statement of cash flows. This ASU is effective for us beginning September 1, 2018, for our fiscal year 2019 and for interim periods within that fiscal year. Early adoption is permitted, including in an interim period. We are currently evaluating the impact the adoption will have on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses. This ASU is intended to provide financial statement users with more decision-useful information about the expected credit losses. This ASU is effective for us beginning September 1, 2020, for our fiscal year 2021 and for interim periods within that fiscal year. Entities may early adopt beginning after December 15, 2018. We are currently evaluating the impact the adoption will have on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which replaces the existing guidance in ASC 840 – Leases. This ASU requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of use asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset, and for operating leases, the lessee would recognize a straight-line total lease expense. This ASU is effective for us beginning September 1, 2019, for our fiscal year 2020 and for interim periods within that fiscal year. We are currently evaluating the impact the adoption will have on our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. ASU No. 2014-09 requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires an entity to disclose sufficient qualitative and quantitative information surrounding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts from customers. This ASU supersedes the revenue recognition requirements in Topic 605, Revenue Recognition and most industry-specific guidance throughout the Industry Topics of the Codification. In August 2015, the FASB issued ASU No. 2015-14 delaying the effective date for adoption. This ASU is now effective for us beginning September 1, 2018, for our fiscal year 2019 and for interim periods within that fiscal year. Subsequently, the FASB issued ASUs in 2016 containing implementation guidance related to ASU No. 2014-09, including: ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which is intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations; ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which is intended to clarify two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance; and ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which contains certain provision and practical expedients in response to identified implementation issues. We will adopt ASU No. 2014-09 and the related ASUs on September 1, 2018, in the first quarter of fiscal 2019. Early application as of the original date is permitted. ASU No. 2014-09 permits the use of either the full or modified retrospective method. We are evaluating the effect this guidance will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.
Fair Value Measurement, Policy | Fair Value Measurements ASC Topic 820, Fair Value Measurement defines fair value as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We determine fair values of derivative instruments and certain other assets, based on the fair value hierarchy established in ASC Topic 820, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. ASC Topic 820 describes three levels within its hierarchy that may be used to measure fair value, and our assessment of relevant instruments within those levels is as follows: Level 1: Values are based on unadjusted quoted prices in active markets for identical assets or liabilities. These assets and liabilities include exchange-traded derivative instruments, Rabbi Trust investments, deferred compensation investments and available-for-sale investments. Level 2: Values are based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. These assets and liabilities include interest rate, foreign exchange, and commodity swaps; forward commodity and freight purchase and sales contracts with a fixed price component; and other OTC derivatives whose value is determined with inputs that are based on exchange traded prices, adjusted for location specific inputs that are primarily observable in the market or can be derived principally from, or corroborated by, observable market data. Level 3: Values are generated from unobservable inputs that are supported by little or no market activity and that are a significant component of the fair value of the assets or liabilities. These unobservable inputs would reflect our own estimates of assumptions that market participants would use in pricing related assets or liabilities. Valuation techniques might include the use of pricing models, discounted cash flow models or similar techniques. The following tables present assets and liabilities, included on our Consolidated Balance Sheets, that are recognized at fair value on a recurring basis, and indicate the fair value hierarchy utilized to determine these fair values. 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.
