Basis Of Presentation, Description Of Business And Summary Of Significant Accounting Policies	'
	1.  BASIS OF PRESENTATION, DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	References to the Company
	References to “Green Plains” or the “Company” in the consolidated financial statements and in these notes to the consolidated financial statements refer to Green Plains Inc., an Iowa corporation, and its subsidiaries.
	Consolidated Financial Statements
	The consolidated financial statements include the accounts of the Company and its controlled subsidiaries. All significant intercompany balances and transactions have been eliminated on a consolidated basis for reporting purposes. Unconsolidated entities are included in the financial statements on an equity basis. Results for the interim periods presented are not necessarily indicative of results to be expected for the entire year.
	The accompanying unaudited consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, or GAAP, for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The consolidated financial statements should be read in conjunction with the Company’s annual report on Form 10-K for the year ended December 31, 2013.
	The unaudited financial information reflects all adjustments which are, in the opinion of management, necessary for a fair presentation of the results of operations, financial position and cash flows for the periods presented. The adjustments are of a normal recurring nature, except as otherwise noted.
	Use of Estimates in the Preparation of Consolidated Financial Statements
	The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Description of Business
	Green Plains is North America’s fourth largest ethanol producer. The Company operates its business within four segments: (1) production of ethanol and distillers grains, collectively referred to as ethanol production, (2) corn oil production, (3) grain handling and storage and cattle feedlot operations, collectively referred to as agribusiness, and (4) marketing, merchant trading and logistics services for Company-produced and third-party ethanol, distillers grains, corn oil and other commodities, and the operation of blending and terminaling facilities, collectively referred to as marketing and distribution. The Company also is a partner in a joint venture to commercialize advanced technologies for growing and harvesting of algal biomass.
	Revenue Recognition
	The Company recognizes revenue when all of the following criteria are satisfied: persuasive evidence of an arrangement exists; risk of loss and title transfer to the customer; the price is fixed and determinable; and collectability is reasonably assured.
	For sales of ethanol, distillers grains and other commodities by the Company’s marketing business, revenue is recognized when title to the product and risk of loss transfer to an external customer. Revenues related to marketing operations for third parties are recorded on a gross basis as the Company takes title to the product and assumes risk of loss. Unearned revenue is reflected on the consolidated balance sheets for goods in transit for which the Company has received payment and title has not been transferred to the customer. Revenues from the Company’s biofuel terminal operations, which include ethanol transload and splash blending services, are recognized when these services are completed.
	The Company routinely enters into fixed-price, physical-delivery ethanol sales agreements. In certain instances, the Company intends to settle the transaction by open market purchases of ethanol rather than by delivery from its own production. These transactions are reported net as a component of revenues. Revenues also include realized gains and losses on related derivative financial instruments, ineffectiveness on cash flow hedges, and reclassifications of realized gains and losses on effective cash flow hedges from accumulated other comprehensive income (loss).
	Sales of agricultural commodities, including cattle, are recognized when title to the product and risk of loss transfer to the customer, which is dependent on the agreed upon sales terms with the customer. These sales terms provide for passage of title either at the time shipment is made or at the time the commodity has been delivered to its destination and final weights, grades and settlement prices have been agreed upon with the customer. Revenues related to grain merchandising are presented gross in the statements of operations with amounts billed for shipping and handling included in revenues and also as a component of cost of goods sold. Revenues from grain storage are recognized as services are rendered.
	Cost of Goods Sold
	Cost of goods sold includes costs for direct labor, materials and certain plant overhead costs. Direct labor includes all compensation and related benefits of non-management personnel involved in the operation of the Company’s ethanol plants. Grain purchasing and receiving costs, other than labor costs for grain buyers and scale operators, are also included in cost of goods sold. Direct materials consist of the costs of corn feedstock, denaturant, and process chemicals. Corn feedstock costs include unrealized gains and losses on related derivative financial instruments not designated as cash flow hedges, inbound freight charges, inspection costs and transfer costs. Corn feedstock costs also include realized gains and losses on related derivative financial instruments, ineffectiveness on cash flow hedges, and reclassifications of realized gains and losses on effective cash flow hedges from accumulated other comprehensive income (loss). Plant overhead costs primarily consist of plant utilities, plant depreciation and outbound freight charges. Shipping costs incurred directly by the Company, including railcar lease costs, are also reflected in cost of goods sold.
	The Company uses exchange-traded futures and options contracts to minimize the effects of changes in the prices of agricultural commodities on its agribusiness segment’s grain and cattle inventories and forward purchase and sale contracts. Exchange-traded futures and options contracts are valued at quoted market prices. These contracts are predominantly settled in cash. The Company is exposed to loss in the event of non-performance by the counter-party to forward purchase and forward sale contracts. Grain inventories held for sale, forward purchase contracts and forward sale contracts in the agribusiness segment are valued at market prices, where available, or other market quotes adjusted for differences, primarily transportation, between the exchange-traded market and the local markets on which the terms of the contracts are based. Changes in the fair value of grain inventories held for sale, forward purchase and sale contracts, and exchange-traded futures and options contracts in the agribusiness segment are recognized in earnings as a component of cost of goods sold.
	Derivative Financial Instruments
	To minimize the risk and the effects of the volatility of commodity price changes primarily related to corn, ethanol and natural gas, the Company uses various derivative financial instruments, including exchange-traded futures, and exchange-traded and over-the-counter options contracts. The Company monitors and manages this exposure as part of its overall risk management policy. As such, the Company seeks to reduce the potentially adverse effects that the volatility of these markets may have on its operating results. The Company may take hedging positions in these commodities as one way to mitigate risk. While the Company attempts to link its hedging activities to purchase and sales activities, there are situations in which these hedging activities can themselves result in losses.
	By using derivatives to hedge exposures to changes in commodity prices, the Company has exposures on these derivatives to credit and market risk. The Company is exposed to credit risk that the counterparty might fail to fulfill its performance obligations under the terms of the derivative contract. The Company minimizes its credit risk by entering into transactions with high quality counterparties, limiting the amount of financial exposure it has with each counterparty and monitoring the financial condition of its counterparties. Market risk is the risk that the value of the financial instrument might be adversely affected by a change in commodity prices or interest rates. The Company manages market risk by incorporating monitoring parameters within its risk management strategy that limit the types of derivative instruments and derivative strategies the Company uses, and the degree of market risk that may be undertaken by the use of derivative instruments.
	The Company evaluates its contracts that involve physical delivery to determine whether they may qualify for the normal purchase or normal sale exemption and are expected to be used or sold over a reasonable period in the normal course of business. Any contracts that do not meet the normal purchase or sale criteria are recorded at fair value with the change in fair value recorded in operating income unless the contracts qualify for, and the Company elects, hedge accounting treatment.
	Certain qualifying derivatives related to the ethanol production segment are designated as cash flow hedges. Prior to entering into cash flow hedges, the Company evaluates the derivative instrument to ascertain its effectiveness. For cash flow hedges, any ineffectiveness is recognized in current period results, while other unrealized gains and losses are reflected in accumulated other comprehensive income until gains and losses from the underlying hedged transaction are realized. In the event that it becomes probable that a forecasted transaction will not occur, the Company would discontinue cash flow hedge treatment, which would affect earnings. These derivative financial instruments are recognized in current assets or other current liabilities at fair value.
	At times, the Company hedges its exposures to changes in the value of inventories and designates certain qualifying derivatives as fair value hedges. The carrying amount of the hedged inventory is adjusted through current period results for changes in the fair value arising from changes in underlying prices. Any ineffectiveness is recognized in current period results to the extent that the change in the fair value of the inventory is not offset by the change in the fair value of the derivative.
	Recent Accounting Pronouncements
	Effective January 1, 2017, the Company will adopt the amended guidance in ASC Topic 606, Revenue from Contracts with Customers. The amended guidance requires revenue recognition to reflect the transfer of promised goods or services to customers and replaces existing revenue recognition guidance. The updated standard permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method nor has it determined the effect of the updated standard on its consolidated financial statements and related disclosures.

Disposition Of Assets [Abstract]	'
Acquisition	'
	2.  ACQUISITION
	Acquisition of Fairmont and Wood River Ethanol Plants
	In November 2013, the Company acquired two ethanol plants, located in Fairmont, Minnesota and Wood River, Nebraska, with a combined annual production capacity of 230 million gallons, from Ethanol Holding Company, LLC, an entity composed of the predecessor owners’ lender group. Consideration of $108.0 million, which included a preliminary amount for working capital, was paid in cash and acquisition-related costs of $0.8 million were recorded in selling, general and administrative expenses. The Company issued approximately $77.0 million of short-term notes payable and term debt shortly after the acquisition, with the acquired assets serving as collateral for these loans, and entered into capital leases totaling $10.0 million for grain facilities that were previously leased by the predecessor owner of the acquired assets. At the time of acquisition, the ethanol plant in Fairmont, Minnesota was not operational; however, upon completion of certain maintenance and enhancement projects, the Company began operations at the plant in early January 2014. The following is a summary of assets acquired and liabilities assumed (in thousands):
	Amounts of Identifiable Assets Acquired
	and Liabilities Assumed
	Accounts receivable	$	119
	Inventory		8,680
	Prepaid expenses and other		2,696
	Property and equipment, net		105,956
	Other assets		4,193
	Current liabilities		-4,260
	Long-term portion of capital leases and
	tax increment financing bond		-7,895
	Other liabilities		-1,489
	Total identifiable net assets	$	108,000
	The amounts above reflect an updated preliminary purchase price allocation, which did not change materially from the initial allocation.  Later this year, upon finalization of the purchase price, including working capital adjustments, the Company will complete the allocation, which it does not expect to differ materially from the preliminary amounts shown above.

Fair Value Disclosures [Abstract]	'
Fair Value Disclosures	'
	3.  FAIR VALUE DISCLOSURES
	The following methods, assumptions and valuation techniques were used in estimating the fair value of the Company’s financial instruments:
	Level 1 – unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 1 unrealized gains and losses on commodity derivatives relate to exchange-traded open trade equity and option values in the Company’s brokerage accounts.
	Level 2 – directly or indirectly observable inputs such as quoted prices for similar assets or liabilities in active markets other than quoted prices included within Level 1; quoted prices for identical or similar assets in markets that are not active; and other inputs that are observable or can be substantially corroborated by observable market data by correlation or other means. Grain inventories held for sale in the agribusiness segment are valued at nearby futures values, plus or minus nearby basis levels.
	Level 3 – 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. The Company currently does not have any recurring Level 3 financial instruments.
	There have been no changes in valuation techniques and inputs used in measuring fair value. The following tables set forth the Company’s assets and liabilities by level for the periods indicated (in thousands):

	(1) Represents long-term restricted cash related to the $22.0 million revenue bond of Green Plains Bluffton.
	The Company believes the fair value of its debt approximated $636.1 million compared to a book value of $631.7 million at June 30, 2014 and the fair value of its debt approximated $775.7 million compared to a book value of $735.2 million at December 31, 2013. The Company estimates the fair value of its outstanding debt using Level 2 inputs. The Company believes the fair values of its accounts receivable and accounts payable approximated book value, which were $120.9 million and $111.7 million, respectively, at June 30, 2014 and $106.8 million and $112.0 million, respectively, at December 31, 2013.
	Although the Company currently does not have any recurring Level 3 financial measurements, the fair values of the tangible assets and goodwill acquired and the equity component of convertible debt represent Level 3 measurements and were derived using a combination of the income approach, the market approach and the cost approach as considered appropriate for the specific assets or liabilities being valued.

Segment Information	'
	4.  SEGMENT INFORMATION
	Company management reviews financial and operating performance in the following four separate operating segments: (1) production of ethanol and distillers grains, collectively referred to as ethanol production, (2) corn oil production, (3) grain handling and storage and cattle feedlot operations, collectively referred to as agribusiness, and (4) marketing, merchant trading and logistics services for Company-produced and third-party ethanol, distillers grains, corn oil and other commodities, and the operation of blending and terminaling facilities, collectively referred to as marketing and distribution. Selling, general and administrative expenses, primarily consisting of compensation of corporate employees, professional fees and overhead costs not directly related to a specific operating segment, are reflected in the table below as corporate activities.
	During the normal course of business, the Company enters into transactions between segments. Examples of these intersegment transactions include, but are not limited to, the ethanol production segment selling ethanol to the marketing and distribution segment and the agribusiness segment selling grain to the ethanol production segment. These intersegment activities are recorded by each segment at prices approximating market and treated as if they are third-party transactions. Consequently, these transactions impact segment performance. However, revenues and corresponding costs are eliminated in consolidation and do not impact the Company’s consolidated results.
	The following tables set forth certain financial data for the Company’s operating segments for the periods indicated (in thousands):

	At June 30, 2014, the Company’s consolidated balance sheet reflects unrealized losses, net of tax, of $13.9 million in accumulated other comprehensive loss. The Company expects that all of the unrealized losses at June 30, 2014 will be reclassified into operating income over the next 12 months as a result of hedged transactions that are forecasted to occur. The amount ultimately realized in operating income, however, will differ as commodity prices change.

During the second quarter of 2014, Green Plains Processing LLC, a wholly-owned subsidiary of Green Plains Inc., issued term debt under a $225 million Term Loan B facility, which was used to repay all term loans and revolving term loans at Green Plains Bluffton, Green Plains Central City, Green Plains Ord, Green Plains Otter Tail and Green Plains Shenandoah, including the Green Plains Bluffton Revenue Bonds. The new facility is secured by the Atkinson, Bluffton, Central City, Ord, Otter Tail and Shenandoah ethanol plants and bears interest at a rate equal to 5.5% plus LIBOR, subject to a 1.0% floor. At June 30, 2014, the interest rate on this term debt was 6.5%. The facility matures on June 30, 2020.
In 2007, Green Plains Bluffton issued $22.0 million of Subordinate Solid Waste Disposal Facility Revenue Bonds bearing interest at 7.50% per annum with the City of Bluffton, Indiana. The revenue bonds required: (1) semi-annual principal and interest payments of approximately $1.5 million through March 1, 2019 and (2) a final principal and interest payment of $3.7 million on September 1, 2019. On July 16, 2014, the revenue bonds were paid in full in accordance with the terms of the $225 million Term Loan B facility.
Green Plains Otter Tail issued $19.2 million in senior notes under New Market Tax Credits financing. The notes bear interest at an annual rate equal to the prime rate (as defined) plus 1.5%, but not less than 4.0%, payable monthly, and require monthly principal payments of approximately $0.3 million beginning in September 2014. These senior notes, which were scheduled to mature in September 2018, were extinguished on April 25, 2014, with $2.2 million of the outstanding obligation forgiven according to terms of the financing, which is included in other income in the consolidated financial statements for the three and six months ended June 30, 2014.
Allowable dividends and other non-overhead distributions from each respective subsidiary are subject to certain additional restrictions including compliance with all loan covenants, terms and conditions, as follows:
•	Green Plains Fairmont and	Up to amounts equal to permitted tax distributions, as defined in the
	Green Plains Wood River	loan agreement
•	Green Plains Holdings II	Up to 40% of net profit before tax, and unlimited if working capital is greater
		than or equal to $20.0 million
•	Green Plains Obion	Up to 40% of net profit before tax, and unlimited if working capital is greater
		than or equal to $15.0 million
•	Green Plains Processing	Unlimited amount may be distributed after free cash flow payment is made, as
		defined in the loan agreement
•	Green Plains Superior	Up to 40% of net profit before tax, and unlimited after free cash flow payment
		is made
In February 2014, the Green Plains Holdings II credit agreement was amended and in June 2014, the Green Plains Obion revolving term loan was amended. The discussions above have been updated to reflect the amendments.
Agribusiness Segment
Green Plains Grain has a $125.0 million senior secured asset-based revolving credit facility with various lenders to provide for working capital financing subject to a borrowing base as defined in the facility. The lenders will make loans up to the maximum commitment based on eligible collateral. The amount of eligible collateral is determined by a calculated borrowing base value equal to the sum of percentages of eligible cash, eligible receivables and eligible inventories, less certain miscellaneous adjustments. Advances are subject to interest charges at a rate per annum equal to the LIBOR rate for the outstanding period plus the applicable margin or a rate per annum equal to the base rate plus the applicable margin. The revolving credit facility matures on August 26, 2016. The revolving credit facility includes total revolving credit commitments of $125.0 million and an accordion feature whereby amounts available under the facility may be increased by up to $75.0 million of new lender commitments upon agent approval. The facility also allows for additional seasonal borrowings up to $50.0 million. The total commitments outstanding under the facility cannot exceed $250.0 million. As security for the revolving credit facility, the lender received a first priority lien on certain cash, inventory, accounts receivable and other assets owned by subsidiaries of the agribusiness segment. In addition to other customary covenants, this revolving credit facility contains restrictions on distributions with respect to capital stock, with exceptions for distributions of up to 40% of net profit before tax, subject to certain conditions.
Marketing and Distribution Segment
Green Plains Trade has a $130.0 million senior secured asset-based revolving credit facility with various lenders to provide for working capital financing subject to a borrowing base as defined in the facility. The lenders will make loans up to $130.0 million based on eligible collateral. The amount of eligible collateral is determined by a calculated borrowing base value equal to the sum of percentages of eligible receivables and eligible inventories, less certain miscellaneous adjustments. The outstanding balance, if any, is subject to interest charges at the lender’s floating base rate plus the applicable margin or LIBOR plus the applicable margin. The revolving credit facility matures on April 26, 2016. In addition to other customary covenants, this revolving credit facility contains restrictions on distributions with respect to capital stock, with exceptions for distributions with respect to tax obligations, subject to certain conditions, whereby distributions may be made in an amount up to 50% of net income if, (a) undrawn availability under this facility, on a pro forma basis, is greater than $10.0 million for the preceding 30 days and (b) as of the date of the distribution, the borrower would be in compliance with the fixed charge coverage ratio on a pro forma basis. At June 30, 2014, Green Plains Trade had $18.0 million presented as restricted cash on the consolidated balance sheets, the use of which was restricted for repayment towards the outstanding loan balance.
In June 2013, subsidiaries of the Company executed a New Markets Tax Credits financing transaction related to the Birmingham, Alabama terminal. In order to facilitate this financing transaction, the Company was required to issue promissory notes payable in the amount of $10.0 million and a note receivable in the amount of $8.1 million. The promissory notes payable and note receivable bear interest at 1% per annum, payable quarterly. Beginning in March 2020, the promissory notes and note receivable each require quarterly principal and interest payments of approximately $0.2 million; the Company retains the right to call $8.1 million of the promissory notes in 2020. The promissory notes payable and note receivable mature on September 15, 2031 and will be fully amortized upon maturity. In connection with the New Markets Tax Credits financing transaction, income tax credits were generated for the benefit of the lender. The Company has guaranteed the lender the value of these income tax credits over their statutory lives, a period of seven years, in the event that the income tax credits are recaptured or reduced. The value of the income tax credits was anticipated to be $5.0 million at the time of the transaction. The Company believes the likelihood of recapture or reduction of the income tax credits is remote, and therefore has not established a liability in connection with this guarantee.
Corporate Activities
In September 2013, the Company issued $120.0 million of 3.25% Convertible Senior Notes due 2018, or the 3.25% Notes. The 3.25% Notes represent senior, unsecured obligations of the Company, with interest payable on April 1 and October 1 of each year. At the time the Company issued the 3.25% Notes, it was only permitted to settle conversions with shares of its common stock. The Company received shareholder approval at its 2014 annual meeting, held in the second quarter, to allow for flexible settlement which gives it the option to settle conversions in cash, shares of common stock, or any combination thereof. The Company intends to satisfy conversion of the 3.25% Notes with cash for the principal amount of the debt and cash or shares of common stock for any related conversion premium. The 3.25% Notes contain liability and equity components which were bifurcated and accounted for separately. The liability component of the 3.25% Notes, as of the issuance date, was calculated by estimating the fair value of a similar liability issued at an 8.21% effective interest rate, which was determined by considering the rate of return investors would require for comparable debt of the Company without conversion rights. The amount of the equity component was calculated by deducting the fair value of the liability component from the principal amount of the 3.25% Notes, resulting in the initial recognition of $24.5 million as debt discount costs recorded in additional paid-in capital. The carrying amount of the 3.25% Notes will be accreted to the principal amount over the remaining term to maturity and the Company will record a corresponding amount of noncash interest expense. Additionally, the Company incurred debt issuance costs of $5.1 million related to the 3.25% Notes and allocated $4.0 million of debt issuance costs to the liability component of the 3.25% Notes. These costs will be amortized to noncash interest expense over the five-year term of the 3.25% Notes. Prior to April 1, 2018, the 3.25% Notes will not be convertible unless certain conditions are satisfied. The initial conversion rate is 47.9627 shares of common stock per $1,000 principal amount of 3.25% Notes, which is equal to an initial conversion price of approximately $20.85 per share. The conversion rate is subject to adjustment upon the occurrence of certain events, including the payment of a quarterly cash dividend that exceeds $0.04 per share. In addition, the Company may be obligated to increase the conversion rate for any conversion that occurs in connection with certain corporate events, including the Company calling the 3.25% Notes for redemption.
The Company may redeem for cash all, but not less than all, of the 3.25% Notes at any time on or after October 1, 2016 if the sale price of the Company's common stock equals or exceeds 140% of the applicable conversion price for a specified time period ending on the trading day immediately prior to the date the Company delivers notice of the redemption. The redemption price will equal 100% of the principal amount of the 3.25% Notes, plus any accrued and unpaid interest. In addition, upon the occurrence of a fundamental change, such as a change in control, holders of the 3.25% Notes will have the right, at their option, to require the Company to repurchase their 3.25% Notes in cash at a price equal to 100% of the principal amount of the 3.25% Notes to be repurchased, plus accrued and unpaid interest. Default with respect to any loan in excess of $10.0 million constitutes an event of default under the 3.25% Notes, which could result in the 3.25% Notes being declared due and payable.
On February 14, 2014, the Company gave notice of its intention to redeem all of its previously-issued and outstanding $90.0 million of 5.75% Convertible Senior Notes due 2015, or the 5.75% Notes, pursuant to the optional redemption right in the indenture governing the 5.75% Notes. The 5.75% Notes were convertible into shares of the Company’s common stock at the conversion rate of 72.5846 shares of common stock for each $1,000 principal amount of 5.75% Notes from February 14, 2014 through February 28, 2014. From March 1, 2014 through March 19, 2014, the conversion rate was adjusted to 72.6961 shares of common stock for each $1,000 principal amount as a result of the quarterly cash dividend. Approximately $89.95 million of the 5.75% Notes were submitted for conversion into 6,532,713 shares of common stock through March 19, 2014. On March 20, 2014, the Company redeemed the remaining 5.75% Notes at par value plus accrued and unpaid interest through March 19, 2014. All $90.0 million of the 5.75% Notes were retired effective March 20, 2014.
Covenant Compliance
The Company, including all of its subsidiaries, was in compliance with its debt covenants as of June 30, 2014.
Capitalized Interest
The Company had $25 thousand in capitalized interest during the three and six months ended June 30, 2014.
Restricted Net Assets
At June 30, 2014, there were approximately $663.0 million of net assets at the Company’s subsidiaries that were not available to be transferred to the parent company in the form of dividends, loans or advances due to restrictions contained in the credit facilities of these subsidiaries.

Stock-Based Compensation [Abstract]	'
Stock-Based Compensation	'
	9.  STOCK-BASED COMPENSATION
	The Company has an equity incentive plan which reserves a total of 3.5 million shares of common stock for issuance pursuant to its terms. The plan provides for the granting of shares of stock, including options to purchase shares of common stock, stock appreciation rights tied to the value of common stock, restricted stock, and restricted and deferred stock unit awards to eligible employees, non-employee directors and consultants. The Company measures share-based compensation grants at fair value on the grant date, adjusted for estimated forfeitures. The Company records noncash compensation expense related to equity awards in its consolidated financial statements over the requisite service period on a straight-line basis. Substantially all of the Company’s existing share-based compensation awards have been determined to be equity awards.
	The following table summarizes stock option activity for the six months ended June 30, 2014:
		Shares	Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)

	(1) Includes in-the-money options totaling 383,850 shares at a weighted-average exercise price of $10.54.
	The Company’s option awards allow employees to exercise options through cash payment to the Company for the shares of common stock or through a simultaneous broker-assisted cashless exercise of a share option through which the employee authorizes the exercise of an option and the immediate sale of the option shares in the open market. The Company uses newly-issued shares of common stock to satisfy its share-based payment obligations.
	The following table summarizes non-vested stock award and deferred stock unit activity for the six months ended June 30, 2014:
		Non-Vested Shares and Deferred Stock Units	Weighted-Average Grant-Date Fair Value		Weighted-Average Remaining Vesting Term

	Vested	-454,438		13.41
	Non-Vested at June 30, 2014	683,005	$	16.07	2.1
	Compensation costs expensed for share-based payment plans described above during the three and six months ended June 30, 2014 were approximately $1.2 million and $4.5 million, respectively, and during the three and six months ended June 30, 2013 were approximately $1.2 million and $3.4 million, respectively. At June 30, 2014, there were $9.2 million of unrecognized compensation costs from share-based compensation arrangements, which are related to non-vested awards. This compensation is expected to be recognized over a weighted-average period of approximately 2.1 years. The potential tax benefit realizable for the anticipated tax deductions of the exercise of share-based payment arrangements generally would approximate 38.5% of these expense amounts.

Earnings Per Share	'
	10.  EARNINGS PER SHARE
	Basic earnings per share, or EPS, is calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed by dividing net income on an if-converted basis for 2013 and the first quarter of 2014, with respect to the 3.25% Notes and the 5.75% Notes, by the weighted average number of common shares outstanding during the period, adjusted for the dilutive effect of any outstanding dilutive securities. All of the 5.75% Notes were retired during the first quarter of 2014. During the second quarter of 2014, the Company received shareholder approval to allow for flexible settlement in cash, shares of common stock, or a combination of cash and shares of common stock for the conversion of the 3.25% Notes. The Company intends to settle conversions in cash for the principal amount and cash or shares of the Company’s common stock for any related conversion premium. Accordingly, beginning in the second quarter of 2014, diluted EPS is computed using the treasury stock method by dividing net income by the weighted average number of common shares outstanding during the period, adjusted for the dilutive effect of any outstanding dilutive securities. The calculations of basic and diluted EPS are as follows (in thousands):
		Three Months Ended				Six Months Ended

	EPS  - diluted	$	0.82	$	0.19	$	1.88	$	0.28
	Excluded from the computations of diluted EPS for the three and six months ended June 30, 2013 were stock-based compensation awards totaling 0.1 million and 0.3 million shares, respectively, because the exercise prices or the grant-date fair value, as applicable, of the corresponding awards were greater than the average market price of the Company’s common stock during the respective periods. Also, for the six months ended June 30, 2013, 6.3 million shares related to the effect of the 5.75% Notes were excluded from the computation of diluted EPS as the inclusion of these shares would have been antidilutive.

	12.  INCOME TAXES
	The Company records income tax expense or benefit during interim periods based on its best estimate of the annual effective tax rate. Certain items are given discrete period treatment and, as a result, the tax effects of such items are reported in full in the relevant interim period.
	Income tax expense for the three and six months ended June 30, 2014 was $17.8 million and $44.3 million, respectively, compared to an income tax expense of $4.3 million and $5.9 million, respectively, for the same periods in 2013. The effective tax rate (calculated as the ratio of income tax expense to income before income taxes) was approximately 35.5% and 37.0% for the three and six months ended June 30, 2014, respectively, and 41.8% and 40.9% for the three and six months ended June 30, 2013, respectively. The effective tax rate for the three and six months ended June 30, 2014 reflects the release of a valuation allowance for state tax credits, as well as new state tax credits generated, that the Company expects to utilize in the future, and an income tax deduction for qualified production activities. This was partially offset by a change in estimate related to the Company’s filing position in various jurisdictions.
	The amount of unrecognized tax benefits for uncertain tax positions was $0.3 million as of June 30, 2014 and $0.2 million as of December 31, 2013. Recognition of these benefits would have a favorable impact on the Company’s effective tax rate. The increase during the six months ended June 30, 2014 is due to a change in estimate related to the Company’s filings in certain jurisdictions.
	The 2014 annual effective tax rate can be affected as a result of variances among the estimates and amounts of full-year sources of taxable income (both among the various states and activity types), the realization of tax credits, adjustments that may arise from the resolution of tax matters under review, variances in the release of valuation allowances and the Company’s assessment of its liability for uncertain tax positions.

	Legal
	The Company is currently involved in litigation that has arisen in the ordinary course of business, but it does not believe that any pending litigation will have a material adverse effect on its financial position, results of operations or cash flows.
	Insurance Recoveries
	In March 2014, the Green Plains Otter Tail ethanol plant was damaged by a fire, which caused substantial property damage and business interruption costs. The Company has property damage and business interruption insurance coverages and, as a result, the fire has not had a material impact on the Company’s financial results through June 30, 2014.

	Use of Estimates in the Preparation of Consolidated Financial Statements
	The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Description Of Business	'
	Description of Business
	Green Plains is North America’s fourth largest ethanol producer. The Company operates its business within four segments: (1) production of ethanol and distillers grains, collectively referred to as ethanol production, (2) corn oil production, (3) grain handling and storage and cattle feedlot operations, collectively referred to as agribusiness, and (4) marketing, merchant trading and logistics services for Company-produced and third-party ethanol, distillers grains, corn oil and other commodities, and the operation of blending and terminaling facilities, collectively referred to as marketing and distribution. The Company also is a partner in a joint venture to commercialize advanced technologies for growing and harvesting of algal biomass.
Revenue Recognition	'
	Revenue Recognition
	The Company recognizes revenue when all of the following criteria are satisfied: persuasive evidence of an arrangement exists; risk of loss and title transfer to the customer; the price is fixed and determinable; and collectability is reasonably assured.
	For sales of ethanol, distillers grains and other commodities by the Company’s marketing business, revenue is recognized when title to the product and risk of loss transfer to an external customer. Revenues related to marketing operations for third parties are recorded on a gross basis as the Company takes title to the product and assumes risk of loss. Unearned revenue is reflected on the consolidated balance sheets for goods in transit for which the Company has received payment and title has not been transferred to the customer. Revenues from the Company’s biofuel terminal operations, which include ethanol transload and splash blending services, are recognized when these services are completed.
	The Company routinely enters into fixed-price, physical-delivery ethanol sales agreements. In certain instances, the Company intends to settle the transaction by open market purchases of ethanol rather than by delivery from its own production. These transactions are reported net as a component of revenues. Revenues also include realized gains and losses on related derivative financial instruments, ineffectiveness on cash flow hedges, and reclassifications of realized gains and losses on effective cash flow hedges from accumulated other comprehensive income (loss).
	Sales of agricultural commodities, including cattle, are recognized when title to the product and risk of loss transfer to the customer, which is dependent on the agreed upon sales terms with the customer. These sales terms provide for passage of title either at the time shipment is made or at the time the commodity has been delivered to its destination and final weights, grades and settlement prices have been agreed upon with the customer. Revenues related to grain merchandising are presented gross in the statements of operations with amounts billed for shipping and handling included in revenues and also as a component of cost of goods sold. Revenues from grain storage are recognized as services are rendered.
Cost Of Goods Sold	'
	Cost of Goods Sold
	Cost of goods sold includes costs for direct labor, materials and certain plant overhead costs. Direct labor includes all compensation and related benefits of non-management personnel involved in the operation of the Company’s ethanol plants. Grain purchasing and receiving costs, other than labor costs for grain buyers and scale operators, are also included in cost of goods sold. Direct materials consist of the costs of corn feedstock, denaturant, and process chemicals. Corn feedstock costs include unrealized gains and losses on related derivative financial instruments not designated as cash flow hedges, inbound freight charges, inspection costs and transfer costs. Corn feedstock costs also include realized gains and losses on related derivative financial instruments, ineffectiveness on cash flow hedges, and reclassifications of realized gains and losses on effective cash flow hedges from accumulated other comprehensive income (loss). Plant overhead costs primarily consist of plant utilities, plant depreciation and outbound freight charges. Shipping costs incurred directly by the Company, including railcar lease costs, are also reflected in cost of goods sold.
	The Company uses exchange-traded futures and options contracts to minimize the effects of changes in the prices of agricultural commodities on its agribusiness segment’s grain and cattle inventories and forward purchase and sale contracts. Exchange-traded futures and options contracts are valued at quoted market prices. These contracts are predominantly settled in cash. The Company is exposed to loss in the event of non-performance by the counter-party to forward purchase and forward sale contracts. Grain inventories held for sale, forward purchase contracts and forward sale contracts in the agribusiness segment are valued at market prices, where available, or other market quotes adjusted for differences, primarily transportation, between the exchange-traded market and the local markets on which the terms of the contracts are based. Changes in the fair value of grain inventories held for sale, forward purchase and sale contracts, and exchange-traded futures and options contracts in the agribusiness segment are recognized in earnings as a component of cost of goods sold.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	To minimize the risk and the effects of the volatility of commodity price changes primarily related to corn, ethanol and natural gas, the Company uses various derivative financial instruments, including exchange-traded futures, and exchange-traded and over-the-counter options contracts. The Company monitors and manages this exposure as part of its overall risk management policy. As such, the Company seeks to reduce the potentially adverse effects that the volatility of these markets may have on its operating results. The Company may take hedging positions in these commodities as one way to mitigate risk. While the Company attempts to link its hedging activities to purchase and sales activities, there are situations in which these hedging activities can themselves result in losses.
	By using derivatives to hedge exposures to changes in commodity prices, the Company has exposures on these derivatives to credit and market risk. The Company is exposed to credit risk that the counterparty might fail to fulfill its performance obligations under the terms of the derivative contract. The Company minimizes its credit risk by entering into transactions with high quality counterparties, limiting the amount of financial exposure it has with each counterparty and monitoring the financial condition of its counterparties. Market risk is the risk that the value of the financial instrument might be adversely affected by a change in commodity prices or interest rates. The Company manages market risk by incorporating monitoring parameters within its risk management strategy that limit the types of derivative instruments and derivative strategies the Company uses, and the degree of market risk that may be undertaken by the use of derivative instruments.
	The Company evaluates its contracts that involve physical delivery to determine whether they may qualify for the normal purchase or normal sale exemption and are expected to be used or sold over a reasonable period in the normal course of business. Any contracts that do not meet the normal purchase or sale criteria are recorded at fair value with the change in fair value recorded in operating income unless the contracts qualify for, and the Company elects, hedge accounting treatment.
	Certain qualifying derivatives related to the ethanol production segment are designated as cash flow hedges. Prior to entering into cash flow hedges, the Company evaluates the derivative instrument to ascertain its effectiveness. For cash flow hedges, any ineffectiveness is recognized in current period results, while other unrealized gains and losses are reflected in accumulated other comprehensive income until gains and losses from the underlying hedged transaction are realized. In the event that it becomes probable that a forecasted transaction will not occur, the Company would discontinue cash flow hedge treatment, which would affect earnings. These derivative financial instruments are recognized in current assets or other current liabilities at fair value.
	At times, the Company hedges its exposures to changes in the value of inventories and designates certain qualifying derivatives as fair value hedges. The carrying amount of the hedged inventory is adjusted through current period results for changes in the fair value arising from changes in underlying prices. Any ineffectiveness is recognized in current period results to the extent that the change in the fair value of the inventory is not offset by the change in the fair value of the derivative.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	Effective January 1, 2017, the Company will adopt the amended guidance in ASC Topic 606, Revenue from Contracts with Customers. The amended guidance requires revenue recognition to reflect the transfer of promised goods or services to customers and replaces existing revenue recognition guidance. The updated standard permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method nor has it determined the effect of the updated standard on its consolidated financial statements and related disclosures.
