NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

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 Renewable Energy, Inc., an Iowa corporation, and its subsidiaries.

Consolidated Financial Statements

The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and entities which it controls. 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, 2012.

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, collectively referred to as agribusiness, and (4) marketing 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. Additionally, the Company is a partner in a joint venture that was formed to commercialize advanced photo-bioreactor technologies for the 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 as these services are rendered.

7

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 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 inventories and forward purchase and sales contracts. Exchange-traded futures and options contracts are valued at quoted market prices. 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. 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 sales contracts.

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 purchases or normal sales 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 sales 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.

8

Certain qualifying derivatives within 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, 2013, the Company adopted the amended guidance in ASC Topic 210, Balance Sheet. The amended guidance addresses disclosure of offsetting financial assets and liabilities. It requires entities to add disclosures showing both gross and net information about instruments and transactions eligible for offset in the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. The updated disclosures have been implemented retrospectively and do not impact the Company’s financial position or results of operations.

Effective January 1, 2013, the Company adopted the amended guidance in ASC Topic 220, Comprehensive Income. The amended guidance requires entities to disclose additional information about reclassification adjustments, including (1) changes in accumulated other comprehensive income by component and (2) significant items reclassified out of accumulated other comprehensive income by presenting the amount reclassified and the individual income statement line items affected. The updated disclosures have been implemented prospectively and do not impact our financial position or results of operations. Refer toNote 10, Stockholders’ Equity, for expanded disclosures.

2.  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 Company believes the fair values of its debt, accounts receivable and accounts payable approximate book value, which were  $571.9 million,$106.0 million and $79.4 million, respectively, at June 30, 2013and $663.3 million,  $80.5 million and $95.6 million, respectively, at December 31, 2012. The Company estimates the fair value of its outstanding debt using Level 2 inputs.

Although the Company currently does not have any recurring Level 3 financial measurements, the fair values of the tangible assets and goodwill acquired 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 being valued.

3.  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, collectively referred to as agribusiness, and (4) marketing 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.

In December 2012, the Company sold twelve grain elevators located in northwestern Iowa and western Tennessee. The transaction involved approximately 32.6 million bushels, or 83%, of the Company’s reported agribusiness grain storage capacity and all of its agronomy and retail petroleum operations. The divested assets were reported within the Company’s agribusiness segment.

In June 2013, the Company acquired an ethanol plant located in Atkinson, Nebraska for approximately $15.2 million, with the capacity to produce approximately 50 million gallons of ethanol per year.The plant began ethanol production during the third quarter of 2013. Also in June 2013, the Company acquired a grain elevator in Archer, Nebraska with current storage capacity of 0.2 million bushels. The Company has begun construction of a flat storage facility to add 1.0 million bushels of grain storage capacity at this location before the 2013 fall harvest.

Agribusiness Segment

Green Plains Grain has a $195.0 millionsenior secured revolving credit facility with various lenders subject to a borrowing base as defined in the facility. The revolving credit facility matures on October 28, 2013.

The revolving credit facility includes total revolving credit commitments of $195.0 million and an accordion feature whereby amounts available under the facility may be increased by up to $55.0 million of new lender commitments upon agent approval. 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. 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. 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. We expect to extend or refinance the revolving credit facility prior to its maturity date.

Subsidiaries within the agribusiness segment were in compliance with their debt covenants as ofJune 30, 2013.

Marketing and Distribution Segment

Green Plains Trade has a senior secured asset-based revolving credit facility pursuant to which the lender will loan up to $130.0 million on eligible collateral. This credit facility was increased from $70.0 million in April 2013. The amount of eligible collateral is determined by a calculated borrowing base value equal to the sum ofpercentages 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.  At June 30, 2013, Green Plains Trade had $12.1 million in cash that was restricted for repayment of the then outstanding loan balance. Such cash is presented in restricted cash on the consolidated balance sheets. The revolving credit facility expires on April 25, 2016.  In addition to other customary covenants, this revolving credit facility contains restrictions on distributions with respect to capital stock, with exceptions (i) for distributions with respect to tax obligations, subject to certain conditions, and (ii) 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.

In June 2013, subsidiaries of the Companyexecuted a New Markets Tax Credits financing transaction. In order to facilitate this financing transaction, the Company was required toissuepromissory 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 receivablebear interest at 1% per annum, payable quarterly. Beginning in March 2020,the promissory notes and note receivable eachrequire quarterly

18

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 face 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 the recapture or reduction of the income tax credits is remote, and therefore has not established a liability in connection with this guarantee.

Subsidiaries within the marketing and distribution segment were in compliance with their debt covenants as of June 30, 2013.

Corporate Activities

In November 2010, the Company issued $90.0 million of 5.75% Convertible Senior Notes due 2015. The Notes represent senior, unsecured obligations of the Company, with interest payable on May 1 and November 1 of each year. The Notes may be converted into shares of the Company’s common stock and cash in lieu of fractional shares of the common stock based on a conversion rate equal to 69.7788 shares of the common stock per $1,000 principal amount of Notes, which is equal to a conversion price of $14.33 per share. The conversion rate is subject to adjustment upon the occurrence of specified events. The Company may redeem for cash all, but not less than all, of the Notes at any time on and after November 1, 2013, if the last reported sale price of the Company’s common stock equals or exceeds 140% of the applicable conversion price for a specified time period, at a redemption price equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest.Default with respect to any loan in excess of $10.0 million constitutes an event of default under the convertible senior notes, which could result in the convertible senior notes being declared due and payable.

A $27.2 million note payable to a subsidiary of NTR plc, which previously was the Company’s largest shareholder, was paid in full during the first quarter of 2013.

Capitalized Interest

The Company had no capitalized interest during the six months ended June 30, 2013.

At June 30, 2013, there were approximately $539.0 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.

8.  STOCK-BASED COMPENSATION

The Company has equity incentive plans which reserve a combined total of 3.5 million shares of common stock for issuance pursuant to their terms. The plans provide 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’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, 2013:

	Non-Vested Shares and Deferred Stock Units	Weighted-Average Grant-Date Fair Value		Weighted-Average Remaining Vesting Term (in years)
Nonvested at December 31, 2012	628,090	$	11.41
Granted	565,651		9.60
Forfeited	-		-
Vested	(455,683)		10.88
Nonvested at June 30, 2013	738,058	$	10.35	2.0

Compensation costs expensed for share-based payment plans described above during the three and six months ended June 30, 2013 were approximately $1.2 million and $3.4 million, respectively and during the three and six months ended June 30, 2012 were approximately $1.0 million and $3.3 million, respectively. At June 30, 2013, there were $6.4 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 2.0 years. The potential tax benefit realizable for the anticipated tax deductions of the exercise of share-based payment arrangements generally would approximate 38% of these expense amounts.

9.  EARNINGS PER SHARE

Basic earnings per common shares, 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 as-if-converted basis available to common stockholders by the weighted average number of common shares outstanding during the period, adjusted for the dilutive effect of any outstanding dilutive securities. The reconciliations of net income to net income on an as-if-converted basis and basic and diluted earnings per share are as follows (in thousands):

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 and0.3 million shares, respectively, and for the three and six months ended June 30, 2012 were stock-based compensation awards totaling 1.3 and 1.0 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. For the six months ended June 30, 2013, and the three and six months ended June 30, 2012,6.3 million,6.4 million and 6.5 million shares, respectively, related to the effect of the convertible debt and stock-based compensation awards, if applicable, were also excluded from the computation of diluted EPS as the inclusion of these shares would have been antidilutive. As consideration for the acquisition of the Lakota and Riga ethanol plants in October 2010, the Company issued warrants for 700,000 shares of its stock at a price of $14.00 per share exercisable for a period of three years from the closing date. The warrants are excluded from the computations of diluted EPS as the exercise price is greater than the average market price of the Company’s common stock for the three and six month periods ended June 30, 2013 and 2012.

11.  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, 2013 was $4.3 million and $5.9 million, respectively, compared to an income tax benefit of $4.1 million and $12.1 million, respectively, for the same periods in 2012. The effective tax rate (calculated as the ratio of income tax expense to income before income taxes) was approximately 41.8% and40.9% for the three and six months ended June 30, 2013, respectively,and 35.4% and 37.5% for the three and six months ended June 30 2012, respectively. The effective tax rate for the three and six months ended June 30, 2013 reflects the reduction in tax benefit for stock-based compensation awards vested during the period.

The Company’s unrecognized tax benefits at June 30, 2013 and December 31, 2012 were immaterial. There was no change in the Company’s liabilities related to unrecognized tax benefits during the first six months of 2013.  

The 2013 annual effective tax rate can be affected as a result of variances among the estimates and amounts of full-year sources of taxable income (among the various states), 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.

Overview

We are a leading, vertically-integrated producer, marketer and distributor of ethanol. We focus on generating stable operating margins through our diversified business segments and our risk management strategy. We believe that owning and operating strategically-located assets throughout the ethanol value chain enables us to mitigate changes in commodity prices and differentiates us from companies focused only on ethanol production. Today, we have operations throughout the ethanol value chain, beginning upstream with our grain handling and storage operations, continuing through our ethanol, distillers grains and corn oil production operations and ending downstream with our ethanol marketing, distribution and blending facilities.

24

We review our operations within the following four separate operating segments:

· Ethanol Production. We are North America’s fourth largest ethanol producer. We operate a total of nine ethanol plants in Indiana, Iowa, Michigan, Minnesota, Nebraska and Tennessee. In June 2013, we acquired an ethanol plant located in Atkinson, Nebraska with the capacity to produce approximately 50 million gallons of ethanol per year, or mmgy.We began operations at the ethanol plant early in the third quarter of 2013. We have the capacity at our ten plants  to collectively consume approximately 280 million bushels of corn per year and produce approximately 790 mmgy of ethanol and approximately 2.2 million tons of distillers grains annually.

· Corn Oil Production. We operate corn oil extraction systems at our nine operating ethanol plants, with the capacity to produce approximately 155 million pounds annually. We plan to install corn oil extraction technology at the Atkinson plant in 2013. The corn oil systems are designed to extract non-edible corn oil, a value-added product, from the whole stillage process immediately prior to production of distillers grains. Industrial uses for corn oil include feedstock for biodiesel, livestock feed additives, rubber substitutes, rust preventatives, inks, textiles, soaps and insecticides.

· Agribusiness. Within our bulk grain business, we have four grain elevators with approximately 5.9 million bushels of total storage capacity. In June 2013, we acquired a grain elevator in Archer, Nebraska with current storage capacity of 0.2 million bushels; however, we have begun construction of a flat storage facility to add 1.0 million bushels of grain storage capacity at this location by the2013 fall harvest. Our ethanol plants have approximately 13.1 million bushels of additional storage capacity. We believe our bulk grain business provides synergies with our ethanol production segment as it supplies a portion of the feedstock for our ethanol plants.

· Marketing and Distribution.Our in-house marketing business is responsible for the sale, marketing and distribution of all ethanol, distillers grains and corn oil produced at our ethanol plants. We also market and provide logistical services for ethanol and other commodities for third-party producers. Additionally, our wholly-owned subsidiary, BlendStar LLC, operates eight blending or terminaling facilities with approximately 831 mmgy of total throughput capacity in seven south central U.S. states. To optimize the value of our assets, we utilize a portion of our railcar fleet to transport crude oil for third parties. At June 30, 2013, we had 632 railcars deployed for crude oil transportation.

We intend to continue to take a disciplined approach in evaluating new opportunities related to potential acquisition of additional ethanol plants by considering whether the plants meet our design, engineering, valuation and geographic criteria. In our marketing and distribution segment, our strategy is to expand our marketing efforts by entering into new or renewal contracts with other ethanol producers and realize additional profit margins by optimizing our commodity logistics.  During 2013 and 2014, we plan to add between five and ten million bushels per year of grain storage capacity around our ethanol plants to take advantage of our current grain handling infrastructure and processing demand. We also intend to pursue opportunities to develop or acquire additional grain elevators, specifically those located near our ethanol plants. We believe that owning additional grain handling and storage operations in close proximity to our ethanol plants enables us to strengthen relationships with local corn producers, allowing us to source corn more effectively and at a lower average cost. We also own approximately 52% of BioProcess Algae LLC, which was formed to commercialize advanced photo-bioreactor technologies for growing and harvesting algal biomass. We continue to support the BioProcess Algae joint venture.

Industry Factors Affecting our Results of Operations

Variability of Commodity Prices.  Our operations and our industry are highly dependent on commodity prices, especially prices for corn, ethanol, distillers grains and natural gas. Because the market prices of these commodities are not always correlated, at times ethanol production may be unprofitable. As commodity price volatility poses a significant threat to our margin structure, we have developed a risk management strategy focused on locking in favorable operating margins when available. We continually monitor market prices of corn, natural gas and other input costs relative to the prices for ethanol and distillers grains at each of our production facilities. We create offsetting positions by using derivative instruments, fixed-price purchases and sales contracts, or a combination of strategies within strict limits. Our primary focus is not to manage general price movements of individual commodities, for example to minimize the cost of corn consumed, but rather to lock in favorable profit margins whenever possible. By using a variety of risk management tools and hedging strategies, including our internally-developed real-time margin management system, we believe we are able to maintain a disciplined approach to price risks.

A combination of factors resulted in compressed ethanol margins in 2012. The ethanol industry increased production in the fourth quarter of 2011 to meet demand from ethanol blenders seeking to take advantage of the volumetric ethanol excise

25

tax credit prior to its expiration on December 31, 2011. As a result, ethanol stocks at the end of 2011 exceeded normal market levels which caused ethanol margins to compress to near break-even levels in the first half of 2012. Additionally, corn prices traded to all-time highs during 2012 due to drought conditions in the midwestern region of the United States. According to the Energy Information Administration, or EIA, as an industry, ethanol producers have responded to these factors by reducing production by approximately 4.9% in 2012 compared to 2011. EIA data also show ethanol imports increased from 174 million gallons in 2011 to 533 million gallons in 2012. Under the Renewable Fuels Standard II, or RFS II, certain parties are obligated to blend, in the aggregate, 2.0 billion gallons of advanced biofuels in 2012. During 2012, sugarcane ethanol imported from Brazil, which totaled approximately 530 million gallons, has been one of the most economical means for obligated parties to meet this standard. Effective May 1, 2013, the Brazilian government increased the required percentage of ethanol in vehicle fuel sold in Brazil to 25 percent (from 20 percent) due to arise in sugarcane production, which could possibly limit ethanol exports from Brazil into the U.S.

U.S. ethanol production reached its lowest level since 2010 in the first halfof 2013, averaging an annualized rate of 12.7 billion gallons in the first half of 2013 compared with 13.9 billion gallons in the first half of 2012 and the 13.8 billion gallon RFS II mandate for 2013. As a result of the U.S. ethanol industry rationalizing production, inventory stocks reached a low of 649 million gallons at the end of June 2013, the lowest level since October 2010. Lower production and lower stocks have had a positive effect on ethanol margins in the first half of 2013, which are significantly better than during the first half of 2012.In the first half of 2013, ethanol margins have been steadily improving; however, the margin structure for the third quarter of 2013 will be dependent on access to corn supplies late in the quarter, prior to the 2013 harvest. We believe that U.S. ethanol production levels will continue to adjust to supply and demand factors for ethanol and corn.

There may be periods of time that, due to the variability of commodity prices and compressed margins, we reduce or cease ethanol production operations at certain of our ethanol plants. In 2012, we reduced production volumes at several of our ethanol plants in direct response to unfavorable operating margins, and have continued our production during the first half of 2013 at approximately93% of our total capacity.The reduced production rates increase yield and optimize cash flow in lower margin environments.

Reduced Availability of Capital.  Some ethanol producers have faced financial distress over the past few years, culminating with bankruptcy filings by several companies. This, in combination with continued volatility in the capital markets, has resulted in reduced availability of capital for the ethanol industry in general. In this market environment, we may experience limited access to incremental financing.

Legislation.  Federal and state governments have enacted numerous policies and incentives to encourage the usage of domestically-produced alternative fuels. Passed in 2007 as part of the Energy Independence and Security Act, RFS II has been, and we expect will continue to be, a driving factor in the growth of ethanol usage. On April 10, 2013 the Renewable Fuel Standard Elimination Act was introduced as H.R. 1461. The bill is targeted to repeal the renewable fuel program of the Environmental Protection Agency, or EPA.  Also introduced on April 10, 2013 was the RFS Reform Bill, H.R. 1462, which would prohibit more than ten percent ethanol in gasoline and reduce the RFS II mandated volume of renewable fuel. On May 14, 2013, the Domestic Alternatives Fuels Act of 2013 was introduced in the U.S. House of Representatives as H.R. 1959 to allow ethanol produced from natural gas to be used to meet the RFS II mandate. These bills were assigned to a congressional committee, which will consider them before possibly sending any on to the House or Senate as a whole.

To further drive the increased adoption of ethanol, Growth Energy, an ethanol industry trade association, and a number of ethanol producers requested a waiver from the EPA to increase the allowable amount of ethanol blended into gasoline from the current 10% level, or E10, to a 15% level, or E15. Through a series of decisions beginning in October 2010, the EPA has granted a waiver for the use of E15 in model year 2001 and newer passenger vehicles, including cars, sport utility vehicles, and light pickup trucks.In June 2012, the EPA gave final approval for the sale and use of E15 ethanol blends. On June 24, 2013 the U.S. Supreme Court declined to hear an appeal from the American Petroleum Institute and other organizations challenging the EPA’s decision to permit the sale of E15. According to the EPA, as of December 31, 2012, 79 fuel manufacturers were registered to sell E15. Approximately 72% of the passenger vehicles in service are eligible to use E15.

The Domestic Alternative Fuels Act of 2012 was introduced on January 18, 2012 in the U.S. House of Representatives and was re-introduced March 15, 2013 as H.R. 1214 to provide liability protection for claims based on the saleor use of certain fuels and fuel additives.Passage of this bill would provide liability protection to consumers in the event they unintentionally put any transportation fuel into their motor vehicle for which such fuel has not been approved. The American Fuel Protection Act of 2013 was introduced on June 5, 2013 in the U.S. House of Representatives to make the United States exclusively liable for certain claims of liability for damages resulting from, or aggravated by, the inclusion of ethanol in transportation fuel.

26

The Master Limited Partnership Parity Act was introduced on April 24, 2013 in the U.S. House of Representatives as H.R. 1696 to extend the publicly traded partnership ownership structure to renewable energy projects. The legislation would provide a level financing system and tax treatment for renewable energy and fossil energy projects. 

Industry Fundamentals.  The ethanol industry is supported by a number of market fundamentals that drive its long-term outlook and extend beyond the short-term margin environment. Following the EPA’s approval, the industry is working to broadly introduce E15 into the retail fuel market. The RFS II mandate increased to 13.8 billion gallons for 2013, 600 million gallons over the mandated volume in 2012, and continues to increase each year through 2015. The domestic gasoline market continues to evolve as refiners are producing more CBOB, a sub-grade (84 octane) gasoline, which requires ethanol or other octane sources to meet the minimum octane rating requirements for the U.S. gasoline market. The demand for ethanol is also affected by the overall demand for transportation fuel, which peaked in 2007 and has been declining steadily since then. Currently, according to the EIA, total gasoline demand in the U.S. is approximately 133 billion gallons annually. Demand for transportation fuel is affected by the number of miles traveled by consumers and the fuel economy of vehicles. Market acceptance of E15 may partially offset the effects of this decrease. Consumer acceptance of E15 and E85 fuels is needed before ethanol can achieve any significant growth in market share. In addition, ethanol export markets, although affected by competition from other ethanol exporters, mainly from Brazil, are expected to remain active in 2013. Overall, the industry is producing below the mandated levels butethanol prices have remained at a discount to gasoline, providing blenders and refiners with an economic incentive to blend.

BioProcess Algae Joint Venture

Our BioProcess Algae joint venture is focused on developing technology to grow and harvest algae, which consume carbon dioxide, in commercially viable quantities. We completed construction of Phase II next to our Shenandoah, Iowa ethanol plant in January 2011 and started operation of our Grower Harvesters™ bioreactors. Phase II allowed for verification of growth rates, energy balances and operating expenses, which are considered to be some of the key steps to commercialization.

BioProcess Algae initiated Phase III and broke ground on a five-acre algae farm at the Shenandoah ethanol plant in the first quarter of 2012. Construction is complete on approximately three acres of the algae farm and the facilities were inoculated with algae in October 2012. Construction of Phase IV, involving the addition of 900-foot Grower Harvester™ reactors and a new processing facility, has begun with completion expected in early 2014.  When completed, expected annual capacity will be 350 to 400 tons of dry wholesale algae. We increased our ownership of BioProcess Algae to approximately 52% during the first quarter of 2013. However, we do not possess the requisite control of this investment to consolidate it.

BioProcess Algae announced on April 22, 2013, that it had been selected to receive a grant of up to $6.4 million from the U.S. Department of Energy as part of a pilot-scale biorefinery project related to production of hydrocarbon fuels meeting military specification. The project will use renewable carbon dioxide, lignocellulosic sugars and waste heat through BioProcess Algae’s Grower Harvester™ technology platform. The objective of the project is to demonstrate technologies to cost-effectively convert biomass into advanced drop-in biofuels. BioProcess Algae is required to contribute a minimum of 50% matching funds for the project.

If we and the other BioProcess Algae members determine that the venture can achieve the desired economic performance from Phases III and IV, we and the other BioProcess Algae members will consider a larger build-out, possibly as large as 200 to 400 acres, of Grower Harvester™ reactors at the Shenandoah, Iowa ethanol plant. Such a build-out may be completed in stages and could take up to two years to complete. Funding for such a project would come from a variety of sources including current partners, new equity investors, debt financing or a combination thereof.

Critical Accounting Policies and Estimates

This disclosure is based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires that we make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and other assumptions that we believe are proper and reasonable under the circumstances. We continually evaluate the appropriateness of estimates and assumptions used in the preparation of our consolidated financial statements. Actual results could differ materially from those estimates. Key accounting policies, including but not limited to those relating to revenue recognition, depreciation of property and equipment, impairment of long-lived assets and goodwill, derivative financial instruments, and accounting for income taxes, are impacted significantly by judgments, assumptions and estimates used in the preparation of the consolidated

27

financial statements. See further discussion of our critical accounting policies and estimates, as well as significant accounting policies, in our annual report on Form 10-K for the year ended December 31, 2012.

Recent Accounting Pronouncements

Effective January 1, 2013, we adopted the amended guidance in ASC Topic 210, Balance Sheet. The amended guidance addresses disclosure of offsetting financial assets and liabilities. It requires entities to add disclosures showing both gross and net information about instruments and transactions eligible for offset in the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. The updated disclosures have been implemented retrospectively and do not impact our financial position or results of operations.

Effective January 1, 2013, we adopted the amended guidance in ASC Topic 220, Comprehensive Income. The amended guidance requires entities to disclose additional information about reclassification adjustments, including (1) changes in accumulated other comprehensive income by component and (2) significant items reclassified out of accumulated other comprehensive income by presenting the amount reclassified and the individual income statement line items affected. The updated disclosures have been implemented prospectively and do not impact our financial position or results of operations.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future material effect on our consolidated financial condition, results of operations or liquidity.

Components of Revenues and Expenses

Revenues.  In our ethanol production segment, our revenues are derived primarily from the sale of ethanol and distillers grains, which is a co-product of the ethanol production process. In our corn oil production segment, our revenues are derived from the sale of corn oil, which is extracted from the whole stillage process immediately prior to the production of distillers grains. In our agribusiness segment, the sale of grain is our primary source of revenue. In our marketing and distribution segment, the sale of ethanol, distillers grains and corn oil that we market for our ethanol plants, the sale of ethanol we market for third-party ethanol plants and the sale of other commodities purchased in the open market represent our primary sources of revenue. Revenues also include net gains or losses from derivatives.

Cost of Goods Sold.Cost of goods sold in our ethanol production and corn oil production segments 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 our ethanol plants. Plant overhead costs primarily consist of plant utilities, plant depreciation and outbound freight charges. Our cost of goods sold in these segments is mainly affected by the cost of corn, natural gas, purchased distillers grains and transportation. Within our corn oil segment, we compensate the ethanol plants for the value of distillers grains displaced during the production process. In the ethanol production segment, corn is our most significant raw material cost. We purchase natural gas to power steam generation in our ethanol production process and to dry our distillers grains. Natural gas represents our second largest cost in this business segment. Cost of goods sold also includes net gains or losses from derivatives.

Grain acquisition costs represent the primary components of cost of goods sold in our agribusiness segment. Grain inventories held for sale, forward purchase contracts and forward sale contracts 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 market value of grain inventories, forward purchase and sale contracts, and exchange-traded futures and options contracts are recognized in earnings as a component of cost of goods sold.

In our marketing and distribution segment, purchases of ethanol, distillers grains and corn oil represent the largest components of cost of goods sold. Transportation expense represents an additional major component of our cost of goods sold in this segment. Transportation expense includes rail car leases, freight and shipping of our ethanol and co-products, as well as costs incurred in storing ethanol at destination terminals.

Selling, General and Administrative Expenses. Selling, general and administrative expenses are recognized at the operating segment level, as well as at the corporate level. These expenses consist of employee salaries, incentives and benefits; office expenses; directorfees; and professional fees for accounting, legal, consulting, and investor relations activities. Personnel costs, which include employee salaries, incentives and benefits, are the largest single category of expenditures in selling, general and administrative expenses. We refer to selling, general and administrative expenses that are

28

not allocable to a segment as corporate activities.

Other Income (Expense).Other income (expense) includes interest earned, interest expense and other non-operating items.

Results of Operations

Segment Results

Our operations fall within the following four segments: (1) production of ethanol and related distillers grains, collectively referred to as ethanol production, (2) corn oil production, (3) grain handling and storage, collectively referred to as agribusiness, and (4) marketing 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. When the Company’s management evaluates segment performance, they review the information provided below, as well as segment earnings before interest, income taxes, noncontrolling interest, depreciation and amortization.

During the normal course of business, our operating segments enter into transactions with one another. For example, our ethanol production and corn oil production segments sell ethanol, distillers grains and corn oil to our marketing and distribution segment and our agribusiness segment sells grain to our 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, intersegment revenues and corresponding costs are eliminated in consolidation, and do not impact our consolidated results.

In December 2012, we sold 12 grain elevators located in northwestern Iowa and western Tennessee consisting of approximately 32.6 million bushels, or approximately 85%, of our grain storage capacity and all of our agronomy and retail petroleum operations, which will affect the comparability of our operating results. The table below reflects selected operating segment financial information for the periods indicated (in thousands):

Three Months Ended June 30, 2013 Compared to the Three Months Ended June 30, 2012

Consolidated Results

Consolidated revenues decreased by $65.7 million for the three months ended June 30, 2013 compared to the same period in 2012 as a result of lower grain and agronomy sales and a decrease in ethanol volumes sold, partially offset by higher average prices realized for ethanol and distillers grains.  The decline in grain and agronomy sales resulted from the sale of certain grain elevators during the fourth quarter of 2012.Gross profit increased by  $14.5 million for the three months ended June 30, 2013 compared to the same period in 2012 primarily as a result of improvedmargins for ethanol production and for marketing and distribution activities. Operating income (loss) increased by  $19.6 million to $18.6 million for the three months ended June 30, 2013 compared to the same period in 2012 as a result of the factors discussed above and a $5.2 million decrease in selling, general and administrative expenses. Selling, general and administrative expenses were lower for the three months ended June 30, 2013 compared to the same period in 2012 due most significantly to the sale of certain grain elevators during the fourth quarter of 2012. Interest expense decreased by $2.1 million for the three months ended June 30, 2013 compared to the same period in 2012 due to lower average debt balances. Income tax expense was $4.3 million for the three months ended June 30, 2013 compared to an income tax benefit of $4.1 million for the same period in 2012.

The following discussion of segment results provides greater detail on period-to-period results.

Ethanol Production Segment

The table below presents key operating data within our ethanol production segment for the periods indicated:

	Three Months Ended June 30,
	2013	2012
Ethanol sold
(thousands of gallons)	172,529	176,729
Ethanol produced
(thousands of gallons)	172,355	171,755
Distillers grains sold
(thousands of equivalent dried tons)	483	472
Corn consumed
(thousands of bushels)	60,965	60,323

Revenues in the ethanol production segment increased by $63.5 million for the three months ended June 30, 2013 compared to the same period in 2012. The increase in revenues was due to higher average ethanol and distillers grains prices

30

realized, partially offset by lower volumes sold. The ethanol production segment produced 172.4 million gallons of ethanol, which represents approximately 93% ofproduction capacity, during the second quarter of 2013.

Cost of goods sold in the ethanol production segment increased by $45.9 million for the three months ended June 30, 2013 compared to the same period in 2012. Consumption of corn increased by 0.6 million bushels and the average cost per bushel increased by 10% during the three months ended June 30,  2013 compared to the same period in 2012. As a result of the factors identified above, gross profit and operating income for the ethanol production segment increased by $17.6 million and $18.0 million, respectively, for the three months ended June 30, 2013 compared to the same period in 2012.

Corn Oil Production Segment

Revenues in the corn oil production segment increased by $0.8 million for the three months ended June 30, 2013 compared to the same period in 2012. During the three months ended June 30, 2013, we sold 39.4 million pounds of corn oil compared to 38.6 million pounds in the same period of 2012. The average price for corn oil was 3% higher for thesecond quarter of 2013 compared to the same period in 2012.

Gross profit and operating income in the corn oil production segment decreased by $1.5 million for the three months ended June 30, 2013 compared to the same period in 2012. The increases in revenues were offset by $2.4 million of additional expense related to higher input costs due to the increased prices for distillers grains during the three months ended June 30, 2013 compared to the same period in 2012.

Agribusiness Segment

Revenues in the agribusiness segment increased by $34.3 million and gross profit and operating income decreased by $7.7 million and $2.2 million, respectively, for the three months ended June 30, 2013 compared to the same period in 2012. We sold 27.2million bushels of grain, including 25.4million bushels to our ethanol production segment, and had no fertilizer sales during the three months ended June 30, 2013 compared to sales of 15.1 million bushels of grain, including 6.1 million bushels to our ethanol production segment, and 30 thousand tons of fertilizer during the same period in 2012. Subsequent to the sale of certain grain elevators and the agronomy business during the fourth quarter of 2012, we increased our focus on supplying corn to our ethanol plants from our agribusiness segment. As a result, 93% of the grain sold by our agribusiness segment was sold to our ethanol plants rather than to external customers. The decrease in gross profit and operating income is due to the factors discussed above.

Marketing and Distribution Segment

Revenues in our marketing and distribution segment increased by $38.6 million for the three months ended June 30, 2013 compared to the same period in 2012. The increase in revenues was primarily due to higher average prices of ethanol and distillers grains and expanded trading and logistic operations and operation of the BlendStar LLC unit-train terminal in Birmingham, Alabama,partially offset by lower ethanol volumes and lower revenues from crude oil transportation. Ethanol and distillers grains revenues increased by  $21.4 million and $13.8 million, respectively. We sold 240.1million and 286.2 million gallons of ethanol during the three months ended June 30, 2013 and 2012, respectively, within the marketing and distribution segment.

Gross profit and operating income for the marketing and distribution segment increased by  $6.8 million and $6.3 million, respectively, for the three months ended June 30, 2013 compared to the same period in 2012, primarily due to profits realized from commodity trading and logistics, higher margins related to the deployment of railcars for crude oil transportationand operation of the Birmingham unit-train terminal.

Intersegment Eliminations

Intersegment eliminations of revenues increased by  $202.9 million for the three months ended June 30, 2013 compared to the same period in 2012 due to increases of $67.0 million and $13.8 million in ethanol and distillers grains, respectively, related to sales from our ethanol production segment to our marketing and distribution segment. In addition, corn sales from our agribusiness segment to our ethanol segment increased $120.7 million between the periods.

31

Corporate Activities

Operating income was impacted by an increase in operating expenses for corporate activities of $0.3 million for the three months ended June 30, 2013 compared to the same period in 2012 primarily due to anincrease in personnel costs.

Income Taxes

We record income tax expense or benefit during interim periods based on our 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. We recorded income tax expense of $4.3 million for the three months ended June 30, 2013 compared to an income tax benefit of $4.1 million for the same period in 2012.  The effective tax rate (calculated as the ratio of income tax expense to income before income taxes) was approximately 41.8% for the three months ended June 30, 2013 compared to 35.4% for the three months ended June 30, 2012.The effective tax rate for the three months ended June 30, 2013 reflects the reduction in tax benefit for stock-based compensation awards vested during the period. The annual effective tax rate can be affected as a result of variances among the estimates and amounts of full-year sources of taxable income (among the various states), 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 an assessment of our liability for uncertain tax positions.

Six Months Ended June 30, 2013 Compared to the Six Months Ended June 30, 2012

Consolidated Results

Consolidated revenues decreased by  $75.6 million for the six months ended June 30, 2013 compared to the same period in 2012 as a result of lower grain and agronomy sales due to the sale of certain grain elevators during the fourth quarter of 2012and a decrease in ethanol volumes sold, partially offset by higher average prices realized for ethanol and distillers grains. Gross profit increased by  $32.9 million for the six months ended June 30, 2013 compared to the same period in 2012 primarily as a result of improvedmargins for ethanol production and for marketing and distribution activities. Operating income (loss) increased by $43.4 million to $31.3 million for the six months ended June 30, 2013 compared to the same period in 2012 as a result of the factors discussed above. Selling, general and administrative expenses were $10.5million lower for the six months ended June 30, 2013 compared to the same period in 2012 due most significantly to the sale of certain grain elevators during the fourth quarter of 2012. Interest expense decreased by $3.1 million for the six months ended June 30, 2013 compared to the same period in 2012 due to lower average debt balances. Income tax expense was $5.9 million for the six months ended June 30, 2013 compared to an income tax benefit of $12.1 million for the same period in 2012.

The following discussion of segment results provides greater detail on period-to-period results.

Ethanol Production Segment

The table below presents key operating data within our ethanol production segment for the periods indicated:

	Six Months Ended June 30,
	2013	2012
Ethanol sold
(thousands of gallons)	343,370	346,349

Distillers grains sold
(thousands of equivalent dried tons)	965	959
Corn consumed
(thousands of bushels)	120,714	122,195

Revenues in the ethanol production segment increased by  $114.4 million for the six months ended June 30, 2013 compared to the same period in 2012. The increase in revenues was due to higher average ethanol and distillers grains prices realized, partially offset by lower volumes sold. The ethanol production segment produced 342.8 million gallons of ethanol, which represents approximately 93% ofproduction capacity, during the first half of 2013.

32

Cost of goods sold in the ethanol production segment increased by $85.5 million for the six months ended June 30, 2013 compared to the same period in 2012. Consumption of corn decreased by 1.5 million bushels, but the average cost per bushel increased by 12% during the six months ended June 30, 2013 compared to the same period in 2012. As a result of the factors identified above, gross profit and operating income for the ethanol production segment increased by $28.9 million and $29.6 million, respectively, for the six months ended June 30, 2013 compared to the same period in 2012.

Corn Oil Production Segment

Revenues in the corn oil production segment increased by $3.0 million for the six months ended June 30, 2013 compared to the same period in 2012. During the six months ended June 30, 2013, we sold 77.5 million pounds of corn oil compared to 72.1 million pounds in the same period of 2012. The average price for corn oil was 5% higher for the first half of 2013 compared to the same period in 2012.

Gross profit and operating income in the corn oil production segment decreased by $1.6 million for the six months ended June 30, 2013 compared to the same period in 2012. The increases in revenues were offset by $4.6 million of additional expense related to higher input costs due to the increased prices for distillers grains during the six months ended June 30, 2013 compared to the same period in 2012.

Agribusiness Segment

Revenues in the agribusiness segment increased by $3.1 million and gross profit and operating income decreased by $12.7 million and $2.5 million, respectively, for the six months ended June 30, 2013 compared to the same period in 2012. We sold 38.2million bushels of grain, including 34.1million to our ethanol production segment, and had no fertilizer sales during the six months ended June 30, 2013 compared to sales of 29.5 million bushels of grain, including 13.0 million bushels to our ethanol production segment, and 32 thousand tons of fertilizer during the same period in 2012. Subsequent to the sale of certain grain elevators and the agronomy business during the fourth quarter of 2012, we increased our focus on supplying corn to our ethanol plants from our agribusiness segment. As a result, 89% of the grain sold by our agribusiness segment was sold to our ethanol plants rather than to external customers. The decrease in gross profit and operating income is due to the factors discussed above.

Marketing and Distribution Segment

Revenues in our marketing and distribution segment increased by $82.0 million for the six months ended June 30, 2013 compared to the same period in 2012. The increase in revenues was primarily due to higher average prices of ethanol and distillers grains and expanded trading and logistic operations and operation of the BlendStar LLC unit-train terminal in Birmingham, Alabama, partially offset by lower ethanol volumes and lower revenues from crude oil transportation. Ethanol and distillers grains revenues increased by  $39.2 million and $26.2 million, respectively. We sold 479.3million and 537.6 million gallons of ethanol during the six months ended June 30, 2013 and 2012, respectively, within the marketing and distribution segment.

Gross profit and operating income for the marketing and distribution segment increased by $19.7 million and $18.8 million, respectively, for the six months ended June 30, 2013 compared to the same period in 2012, primarily due to profits realized from commodity trading and logistics, higher margins related to the deployment of railcars for crude oil transportationand the operation of the Birmingham unit-train terminal.

Intersegment Eliminations

Intersegment eliminations of revenues increased by $278.2 million for the six months ended June 30, 2013 compared to the same period in 2012 due to increases of $104.8 million and $28.9 million in ethanol and distillers grains, respectively, related to sales from our ethanol production segment to our marketing and distribution segment. In addition, corn sales from our agribusiness segment to our ethanol segment increased $140.5 million between the periods.

Corporate Activities

Operating income was impacted by a decrease in operating expenses for corporate activities of $0.5 million for the six months ended June 30, 2013 compared to the same period in 2012 primarily due to a decrease in consulting and promotional costs, which were partially offset by increased fees for professional services during the first six months of 2013.

33

Income Taxes

We record income tax expense or benefit during interim periods based on our 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. We recorded income tax expense of $5.9 million for the six months ended June 30, 2013 compared to an income tax benefit of $12.1 million for the same period in 2012.  The effective tax rate (calculated as the ratio of income tax expense to income before income taxes) was approximately 40.9% for the six months ended June 30, 2013 compared to 37.5% for the six months ended June 30, 2012.The effective tax rate for the six months ended June 30, 2013 reflects the reduction in tax benefit for stock-based compensation awards vested during the period. The annual effective tax rate can be affected as a result of variances among the estimates and amounts of full-year sources of taxable income (among the various states), 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 an assessment of our liability for uncertain tax positions.

EBITDA

Management uses earnings before interest, income taxes, noncontrolling interests, depreciation and amortization, or EBITDA, to measure our financial performance and to internally manage our businesses. Management believes that EBITDA provides useful information to investors as a measure of comparison with peer and other companies. EBITDA should not be considered an alternative to, or more meaningful than, net income or cash flow as determined in accordance with generally accepted accounting principles. EBITDA calculations may vary from company to company. Accordingly, our computation of EBITDA may not be comparable with a similarly titled measure of another company. The following sets forth the reconciliation of net income (loss) to EBITDA for the periods indicated (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2013		2012		2013		2012
Net income (loss) attributable to Green Plains	$	5,965	$	(7,550)	$	8,520	$	(20,242)
Net loss attributable to noncontrolling interests		-		(4)		-		(8)
Interest expense		7,762		9,842		15,833		18,909
Income tax expense (benefit)		4,288		(4,145)		5,886		(12,145)

EBITDA	$	30,450	$	11,402	$	55,283	$	12,931

Liquidity and Capital Resources

On June 30, 2013, we had $213.5 million in cash and equivalents, excluding restricted cash, comprised of $56.4 million held at our parent company and the remainder at our subsidiaries. We also had up to an additional $220.2  million available under revolving credit agreements at our subsidiaries, some of which was subject to borrowing base restrictions or other specified lending conditions at June 30, 2013. Funds held at our subsidiaries are generally required for their ongoing operational needs and distributions from our subsidiaries are restricted pursuant to their credit agreements. At June 30, 2013, there were approximately $539.0 million of net assets at our 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.

We incurred capital expenditures of $4.9 million in the first sixmonths of 2013 for various projects. Capital spending for the remainder of 2013 is expected to be approximately $15.1 million which includes expansion of the grain storage facilities at some of our ethanol plants. The remainder of our capital spending is expected to be financed with available borrowings under our credit facilities and cash provided by operating activities.

Net cash providedby operating activities was $69.8 million for the six months ended June 30, 2013 compared to net cash used by operating activities of  $40.4 million for the same period in 2012.  Operating activities were affected by adecrease in working capital for the six months ended June 30, 2013, primarily consisting of a reduction in grain inventory, partially offset by cash outlays related to payments for deferred grain contract payables and accrued expenses and an increase in accounts receivable.Cash used by operating activities for the six months ended June 30,  2012 included significant cash outflows for deferred grain contract payables partially offset by inventory reductions.  Additionally, during the six months ended June 30,  2013, we had net income of $8.5 million compared witha net loss of $20.3 million for the same period in 2012. Net cash used by investing activities was $21.1 million for the six months ended June 30, 2013, due primarily to the acquisition of an ethanol plant in June 2013 and$4.9 million in capital expenditures. Net cash used by financing activities was $89.6 million

34

for the six months ended June 30, 2013 due primarily to net payments of long-term debttotaling  $32.9 million,the payment of ashort-term note payable of $27.2 million related to a  2012 common stock repurchase anda $40.7 millionnet decrease in short-term debt and inventory financing arrangements used to finance grain inventories. Financing activities were also affected by a $12.7 million decrease in restricted cash related to a revolving credit agreement in the first six months of 2013. Green Plains Trade and Green Plains Grain utilize revolving credit facilities to finance working capital requirements. These facilities are frequently drawn upon and repaid resulting in significant cash movements that are reflected on a gross basis within financing activities as proceeds from and payments on short-term borrowings.

Our business is highly impacted by commodity prices, including prices for corn, ethanol, distillers grains and natural gas. We attempt to reduce the market risk associated with fluctuations in commodity prices through the use of derivative financial instruments. Sudden changes in commodity prices may require cash deposits with brokers or margin calls. Depending on our open derivative positions, we may require significant liquidity with little advanced notice to meet margin calls. We continuously monitor our exposure to margin calls and believe that we will continue to maintain adequate liquidity to cover such margin calls from operating results and borrowings. Increases in grain pricesand hedging activity have led to more frequent and larger margin calls.

We were in compliance with our debt covenants at June 30, 2013. Based upon our forecasts and the current margin environment, we believe certain ethanol production subsidiaries mayrequire capital injections from the parent company at times to maintain compliance with certain covenants during fiscal year2013. We believe we will maintain compliance with our debt covenants at each of our subsidiaries for the upcoming twelve months, or if necessary have sufficient liquidity available at the parent company to resolve a subsidiary’s noncompliance; however, no obligation exists to provide such liquidity for a subsidiary’s compliance. No assurance can be provided that actual operating results will approximate our forecasts or that we will inject the necessary capital into a subsidiary to maintain compliance with its respective covenants. In the event actual results differ significantly from our forecasts and a subsidiary is unable to comply with its respective debt covenants under its credit facility, such subsidiary’s lenders may determine that an event of default has occurred. Upon the occurrence of an event of default, and following notice, the lenders may terminate any commitment and declare the entire unpaid balance due and payable.

We believe that we have sufficient working capital for our existing operations. However, a sustained period of unprofitable operations may strain our liquidity and make it difficult to maintain compliance with our financing arrangements. While we may seek additional sources of working capital in response, we can provide no assurance that we will be able to secure this funding if necessary. We may sell additional equity or borrow additional amounts to improve or preserve our liquidity, expand our existing businesses, or build additional or acquire existing businesses. We can provide no assurance that we will be able to secure the funding necessary for these additional projects or for additional working capital needs at reasonable terms, if at all.

Each term loan, except for the Green Plains Holdings II and Green Plains Otter Tail agreements, has a provision that requires us to make annual special payments equal to a percentage ranging from 65% to 75% of the available free cash flow from the related entity’s operations (as defined in the respective loan agreements), subject to certain limitations. With certain exceptions, the revolving term loans within this segment are generally available for advances throughout the life of the commitment with interest-only payments due each month until the final maturity date.

The term loans and revolving term loans bear interest at LIBOR plus 3.00% to 4.50% or lender-established prime rates. Some have established a floor on the underlying LIBOR index. In some cases, the lender may allow us to elect to pay interest at a fixed interest rate to be determined. As security for the loans, the lenders received a first-position lien on all personal property and real estate owned by the respective entity borrowing the funds, including an assignment of all contracts and rights pertinent to construction and on-going operations of the plant. Additionally, debt facilities of Green Plains Central City and Green Plains Ord are cross-collateralized. These borrowing entities are also required to maintain certain combined financial and non-financial covenants during the terms of the loans.

Green Plains Bluffton issued a $22.0 million Subordinate Solid Waste Disposal Facility Revenue Bond with the city of Bluffton, Indiana, of which $16.7 million remained outstanding at June 30, 2013. The revenue bond requires: semi-annual principal and interest payments of approximately $1.5 million through March 1, 2019; and a final principal and interest payment of $3.745 million on September 1, 2019. The revenue bond bears interest at 7.50% per annum.

36

Green Plains Otter Tail also issued $19.2 million in senior notes under New Market Tax Credits financing of which $19.1 million remained outstanding at June 30, 2013. The notes bear interest at arate 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 October 2014. The notes mature on September 1, 2018 with an expected outstanding balance of $4.7 million upon maturity.

Agribusiness Segment

Green Plains Grain has a $195.0 million senior secured revolving credit facility with various lenders to provide the agribusiness segment with working capital funding subject to a borrowing base as defined in the facility. The revolving credit facility matures on October 28, 2013. Advances of the revolving credit facility are subject to interest charges at a rate per annum equal to the LIBOR rate for the outstanding period, or the base rate, plus the respective applicable margin. At June 30, 2013, $70.0 million on the revolving credit facility was outstanding. As security for the revolving credit facility, the lender receives a first priority lien on certain cash, inventory, accounts receivable and other assets owned by subsidiaries of the agribusiness segment. We expect to extend or refinance the revolving credit facility prior to its maturity date.

Marketing and Distribution Segment

Green Plains Trade has a senior secured asset-based revolving credit facility of up to $130.0 million, subject to a borrowing base value equal to the sum of percentages of eligible receivables and eligible inventories, less certain miscellaneous adjustments. At June 30, 2013, $34.8 million was outstanding on the revolving credit facility. The revolving credit facility expires on April 25, 2016 and bears interest at the lender’s commercial floating rate plus the applicable margin or LIBOR plus the applicable margin. As security for the loan, the lender received a first-position lien on substantially all of the assets of Green Plains Trade, including accounts receivable, inventory and other property and collateral owned by Green Plains Trade.

In June 2013, subsidiaries of the Company executed a New Markets Tax Credits financing transaction. 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 receivablebear 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. We have guaranteed the lender the face 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. We believe the likelihood of recapture or reduction of the income tax credits is remote, and therefore have not established a liability in connection with this guarantee.

Corporate Activities

We have $90.0 million of 5.75% Convertible Senior Notes due 2015. The Notes represent senior, unsecured obligations, with interest payable on May 1 and November 1 of each year. The Notes may be converted into shares of common stock and cash in lieu of fractional shares of the common stock based on a conversion rate equal to 69.7788 shares of the common stock per $1,000 principal amount of Notes, which is equal to a conversion price of $14.33 per share. The conversion rate is subject to adjustment upon the occurrence of specified events. We may redeem for cash all, but not less than all, of the Notes at any time on and after November 1, 2013, if the last reported sale price of our common stock equals or exceeds 140% of the applicable conversion price for a specified time period, at a redemption price equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest. Payment default with respect to any loan in excess of $10.0 million constitutes an event of default under the convertible senior notes, which could result in the convertible senior notes being declared due and payable.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to various market risks, including changes in commodity prices and interest rates. Market risk is the potential loss arising from adverse changes in market rates and prices. In the ordinary course of business, we enter into various types of transactions involving financial instruments to manage and reduce the impact of changes in commodity prices and interest rates. At this time, we do not expect to have exposure to foreign currency risk as we expect to conduct all of our business in U.S. dollars.

Interest Rate Risk

We are exposed to market risk from changes in interest rates. Exposure to interest rate risk results primarily from holding term and revolving loans that bear variable interest rates. Specifically, we had$571.9 million outstanding in debt as of June 30, 2013, $453.0 million of which is variable-rate in nature. Interest rates on our variable-rate debt are determined based upon the market interest rate of either the lender’s prime rate or LIBOR, as applicable. A 10% change in interest rates would affect our interest cost on such debt by approximately $1.6 million per year in the aggregate. Other details of our outstanding debt are discussed in the notes to the consolidated financial statements included as a part of this report.

Commodity Price Risk

We produce ethanol, distillers grains and corn oil from corn and our business is sensitive to changes in the prices of each of these commodities. The price of corn is subject to fluctuations due to unpredictable factors such as weather; corn planted and harvested acreage; changes in national and global supply and demand; and government programs and policies. We use natural gas in the ethanol production process and, as a result, our business is also sensitive to changes in the price of natural gas. The price of natural gas is influenced by such weather factors as extreme heat or cold in the summer and winter, or other natural events like hurricanes in the spring, summer and fall. Other natural gas price factors include North American exploration and production, and the amount of natural gas in underground storage during both the injection and withdrawal seasons. Ethanol prices are sensitive to world crude-oil supply and demand; crude-oil refining capacity and utilization; government regulation; and consumer demand for alternative fuels. Distillers grains prices are sensitive to various demand factors such as numbers of livestock on feed, prices for feed alternatives, and supply factors, primarily production by ethanol plants and other sources.

We attempt to reduce the market risk associated with fluctuations in the price of corn, natural gas, ethanol, distillers grains and corn oil by employing a variety of risk management and economic hedging strategies. Strategies include the use of forward fixed-price physical contracts and derivative financial instruments, such as futures and options executed on the Chicago Board of Trade and the New York Mercantile Exchange.

38

We focus on locking in operating margins based on a model that continually monitors market prices of corn, natural gas and other input costs against prices for ethanol and distillers grains at each of our production facilities. We create offsetting positions by using a combination of forward fixed-price physical purchases and sales contracts and derivative financial instruments. As a result of this approach, we frequently have gains on derivative financial instruments that are conversely offset by losses on forward fixed-price physical contracts or inventories and vice versa. In our ethanol production segment, gains and losses on derivative financial instruments are recognized each period in operating resultswhile corresponding gains and losses on physical contracts are generally designated as normal purchases or normal sales contracts and are not recognized until quantities are delivered or utilized in production. For cash flow hedges, any ineffectiveness is recognized in current period results, while other unrealized gains and losses are deferred 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, we would discontinue cash flow hedge treatment, which would affect earnings. During the six months ended June 30, 2013, revenues included net losses of $48.7 million and cost of goods sold included net gains of  $4.3 million from derivative financial instruments. To the extent net gains or losses from settled derivative instruments are related to hedging current period production, they are generally offset by physical commodity purchases or sales resulting in the realization of the intended operating margins. However, our results of operations are impacted when there is a mismatch of gains or losses associated with the change in fair value of derivative instruments at the reporting period when the physical commodity purchase or sales has not yet occurred since they are designated as a normal purchase or normal sale.

In our agribusiness segment, inventory positions, physical purchase and sale contracts, and financial derivatives are marked to market with gains and losses included in results of operations.  The market value of derivative financial instruments such as exchange-traded futures and options has a high, but not perfect, correlation to the underlying market value of grain inventories and related purchase and sale contracts.

Ethanol Production Segment

A sensitivity analysis has been prepared to estimate our ethanol production segment exposure to ethanol, corn, distillers grains and natural gas price risk. Market risk related to these factors is estimated as the potential change in net income resulting from hypothetical 10% changes in prices of our expected corn and natural gas requirements, and ethanol and distillers grains output for a one-year period from June 30, 2013. This analysis includes the impact of risk management activities that result from our use of fixed-price purchase and sale contracts and derivatives. The results of this analysis, which may differ from actual results, are as follows (in thousands):

Commodity	Estimated Total Volume Requirements for the Next 12 Months (1)	Unit of Measure	Net Income Effect of Approximate 10% Change in Price
Ethanol	790,000	Gallons	$	93,100
Corn	280,000	Bushels	$	85,381
Distillers grains	2,240	Tons (2)	$	21,682
Natural gas	21,830	MMBTU (3)	$	4,418
(1) Assumes production at full capacity.
(2) Distillers grains quantities are stated on an equivalent dried ton basis.
(3) Millions of British Thermal Units.

Corn Oil Production Segment

A sensitivity analysis has been prepared to estimate our corn oil production segment exposure to corn oil price risk. Market risk related to these factors is estimated as the potential change in net income resulting from hypothetical 10% changes in prices of our expected corn oil output for a one-year period from June 30, 2013. This analysis includes the impact of risk management activities that result from our use of fixed-price sale contracts. Market risk at June 30, 2013,  based on the estimated net income effect resulting from a hypothetical 10% change in such prices, was approximately $1.9million.

Agribusiness Segment

The availability and price of agricultural commodities are subject to wide fluctuations due to unpredictable factors such as weather, plantings, foreign and domestic government farm programs and policies, changes in global demand created by population changes and changes in standards of living, and global production of similar and competitive crops. To reduce price risk caused by market fluctuations in purchase and sale commitments for grain and grain held in inventory, we enter

39

into exchange-traded futures and options contracts that function as economic hedges. The market value of exchange-traded futures and options used for hedging has a high, but not perfect correlation, to the underlying market value of grain inventories and related purchase and sale contracts. The less correlated portion of inventory and purchase and sale contract market value, known as basis, is much less volatile than the overall market value of exchange-traded futures and tends to follow historical patterns. We manage this less volatile risk by constantly monitoring our position relative to the price changes in the market. In addition, inventory values are affected by the month-to-month spread relationships in the regulated futures markets, as we carry inventories over time. These spread relationships are also less volatile than the overall market value and tend to follow historical patterns, but also represent a risk that cannot be directly mitigated. Our accounting policy for our futures and options, as well as the underlying inventory held for saleand purchase and sale contracts, is to mark them to the market and include gains and losses in the consolidated statement of operations in sales and merchandising revenues.

A sensitivity analysis has been prepared to estimate agribusiness segment exposure to market risk of our commodity position (exclusive of basis risk). Our daily net commodity position consists of inventories related to purchase and sale contracts and exchange-traded contracts. The fair value of our position, which is a summation of the fair values calculated for each commodity by valuing each net position at quoted futures market prices, is approximately $0.8 million at June 30, 2013. Market risk at that date, based on the estimated net income effect resulting from a hypothetical 10% change in such prices, was approximately $47 thousand.

Item 4.  Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934, or Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required financial disclosure.

As of the end of the period covered by this report, our management carried out an evaluation, under the supervision of and with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. These disclosure controls and procedures are designed to ensure that information required to be disclosed by us in the reports that it files or submits under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required financial disclosure. Based upon that evaluation, our management, including our Chief Executive Officer and the Chief Financial Officer, concluded that our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining effective internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with generally accepted accounting principles. There were no material changes in our internal control over financial reporting that occurred during the period covered by this quarterly report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1.  Legal Proceedings.

We are currently involved in litigation that has arisen in the ordinary course of business; however, we do not believe that any of this litigation will have a material adverse effect on our financial position, results of operations or cash flows.

Item 1A.  Risk Factors.

Investors should carefully consider the discussion of risks and the other information included in our annual report on Form 10-K for the year ended December 31, 2012 and in this quarterly report on Form 10-Q, including Cautionary

40

Information Regarding Forward-Looking Information, which is included in Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Although we have attempted to discuss key factors, our investors need to be aware that other risks may prove to be important in the future. New risks may emerge at any time and we cannot predict such risks or estimate the extent to which they may affect our financial performance.

The following risk factors should be considered in conjunction with the other information included in, or incorporated by reference in, this quarterly report on Form 10-Q.

The ethanol industry is highly dependent on government usage mandates affecting ethanol production and any changes to such regulation could adversely affect the market for ethanol and our results of operations.

The domestic market for ethanol is largely dictated by federal mandates for blending ethanol with gasoline. The RFS II mandate level for conventional biofuels for 2013 of 13.8 billion gallons approximates currentdomestic production levels. Future demand will be largely dependent upon the economic incentives to blend based upon the relative value of gasoline versus ethanol, taking into consideration the relative octane value ofethanol, environmental requirements and the RFS II mandate. Any significant increase in production capacitybeyond the RFS II mandated level might have an adverse impact on ethanol prices.

Additionally, under the provisions of the Energy Independence and Security Act, the EPA has the authority to waive the mandated RFS II requirements in whole or in part. To grant the waiver, the EPA administrator mustdetermine, in consultation with the Secretaries of Agriculture and Energy, that one of two conditions has beenmet: (1) there is inadequate domestic renewable fuel supply or (2) implementation of the requirement wouldseverely harm the economy or environment of a state, region or the United States. In the third quarter of 2012,the governors of North Carolina and Arkansas, as well as a number of livestock groups, filed waiver requestswith the EPA based on drought conditions. In November 2012, the agency decided not to grant the requestedwaiver. Our operations could be adversely impacted if a waiver is requested and granted in the future.

Due to drought conditions in 2012 and claims that blending of ethanol into the motor fuel supply will beconstrained by unwillingness of the market to accept greater than ten percent ethanol blends (the “blend wall”),legislation aimed at reducing or eliminating the renewable fuel use required by RFS II has beenintroduced in Congress.On April 10, 2013 the Renewable Fuel Standard Elimination Act was introduced as H.R. 1461. The bill is targeted to repeal the renewable fuel program of the Environmental Protection Agency, or EPA.  Also introduced on April 10, 2013 was the RFS Reform Bill, H.R. 1462, which would prohibit more than ten percent ethanol in gasoline and reduce the RFS II mandated volume of renewable fuel. On May 14, 2013, the Domestic Alternatives Fuels Act of 2013 was introduced in the U.S. House of Representatives as H.R. 1959 to allow ethanol produced from natural gas to be used to meet the RFS II mandate. These bills were assigned to a congressional committee, which will consider them before possibly sending any on to the House or Senate as a whole. We believe RFS II is a significant component of nationalenergy policy that reduces dependence on foreign oil by the United States. Our operations could be adverselyimpacted if the RFS Reform Bill of 2013, the RFS Elimination Bill of 2013, or other legislation reducing the RFSII mandate is enacted.

The compliance mechanism for RFS II is generation of renewable identification numbers, or RINs, which aregenerated and attached to renewable fuels such as the ethanol we produce and detached when the renewable fuel isblended into the transportation fuel supply. Detached RINs may be retired by obligated parties to demonstratecompliance with RFS II or may be separately traded in the market. The market price of detached RINs may affect theprice of ethanol in certain U.S. markets as obligated parties may factor these costs into their purchasing decisions.Moreover, at certain price levels for various types of RINs, it becomes more economical to import foreign sugar caneethanol. If changes to RFS II result in significant changes in the price of various types of RINs, it could negativelyaffect the price of ethanol, and our operations could be adversely impacted.

Federal law mandates the use of oxygenated gasoline in the winter in areas that do not meet Clean Air Actstandards for carbon monoxide. If these mandates are repealed, the market for domestic ethanol could be diminished. Additionally, flexible-fuel vehicles receive preferential treatment in meeting corporate average fuel economy, or CAFE, standards. However, high blend ethanol fuels such as E85 result in lower fuel efficiencies.Absent the CAFE preferences, it may be unlikely that auto manufacturers would build flexible-fuel vehicles. Anychange in these CAFE preferences could reduce the growth of E85 markets and result in lower ethanol prices,which could adversely impact our operating results.

To the extent that such federal or state laws or regulations are modified, the demand for ethanol may bereduced, which could negatively and materially affect our ability to operate profitably.

We may be required to pay substantial penalties if we inadvertently trade fraudulent RINs.

In the past, one of our wholly-owned subsidiaries has traded ethanol and associated RINs acquired fromthird-parties, and may make such trades in the future. In 2012, it was discovered that some entities in thebiodiesel industry sold fraudulent biodiesel RINs (biodiesel RINs registered with the EPA that had no physicalrenewable fuel associated with them). The EPA brought enforcement actions against purchasers of the fraudulentbiodiesel RINs, even though they had purchased the RINs without knowledge of their fraudulent nature. If itwere to be discovered that we had purchased ethanol and associated RINs that were determined to be fraudulentethanol RINs, albeit unknowingly, we could be subject to penalties. If assessed at the maximum amount allowedby law, such penalties could be very substantial. EPA policy has been to assess very modest penalties forunknowing purchase of fraudulent RINs prior to 2013. With the industry now on notice of the possibility offraudulent RINs, the EPA may assess much higher penalties going forward, and if we were subject to suchpenalties, it could have an adverse impact on our profitability.

Segment Information [Abstract]

Segment Information

3.  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, collectively referred to as agribusiness, and (4) marketing 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.

In December 2012, the Company sold twelve grain elevators located in northwestern Iowa and western Tennessee. The transaction involved approximately 32.6 million bushels, or 83%, of the Company’s reported agribusiness grain storage capacity and all of its agronomy and retail petroleum operations. The divested assets were reported within the Company’s agribusiness segment.

In June 2013, the Company acquired an ethanol plant located in Atkinson, Nebraska for approximately $15.2 million, with the capacity to produce approximately 50 million gallons of ethanol per year. The plant began ethanol production during the third quarter of 2013. Also in June 2013, the Company acquired a grain elevator in Archer, Nebraska with current storage capacity of 0.2 million bushels. The Company has begun construction of a flat storage facility to add 1.0 million bushels of grain storage capacity at this location before the 2013 fall harvest.

Income Taxes

11.  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, 2013 was $4.3 million and $5.9 million, respectively, compared to an income tax benefit of $4.1 million and $12.1 million, respectively, for the same periods in 2012. The effective tax rate (calculated as the ratio of income tax expense to income before income taxes) was approximately 41.8% and 40.9% for the three and six months ended June 30, 2013, respectively, and 35.4% and 37.5% for the three and six months ended June 30 2012, respectively. The effective tax rate for the three and six months ended June 30, 2013 reflects the reduction in tax benefit for stock-based compensation awards vested during the period.

The Company’s unrecognized tax benefits at June 30, 2013 and December 31, 2012 were immaterial. There was no change in the Company’s liabilities related to unrecognized tax benefits during the first six months of 2013.

The 2013 annual effective tax rate can be affected as a result of variances among the estimates and amounts of full-year sources of taxable income (among the various states), 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.

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 Renewable Energy, Inc., an Iowa corporation, and its subsidiaries.

Consolidated Financial Statements

The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and entities which it controls. 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, 2012.

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, collectively referred to as agribusiness, and (4) marketing 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. Additionally, the Company is a partner in a joint venture that was formed to commercialize advanced photo-bioreactor technologies for the 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 as these services are rendered.

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 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 inventories and forward purchase and sales contracts. Exchange-traded futures and options contracts are valued at quoted market prices. 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. 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 sales contracts.

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 purchases or normal sales 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 sales 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 within 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, 2013, the Company adopted the amended guidance in ASC Topic 210, Balance Sheet. The amended guidance addresses disclosure of offsetting financial assets and liabilities. It requires entities to add disclosures showing both gross and net information about instruments and transactions eligible for offset in the balance sheet and instruments and transactions subject to an agreement similar to a master netting arrangement. The updated disclosures have been implemented retrospectively and do not impact the Company’s financial position or results of operations.

Effective January 1, 2013, the Company adopted the amended guidance in ASC Topic 220, Comprehensive Income. The amended guidance requires entities to disclose additional information about reclassification adjustments, including (1) changes in accumulated other comprehensive income by component and (2) significant items reclassified out of accumulated other comprehensive income by presenting the amount reclassified and the individual income statement line items affected. The updated disclosures have been implemented prospectively and do not impact our financial position or results of operations. Refer to Note 10, Stockholders’ Equity, for expanded disclosures.

Fair Value Disclosures

2.  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):

Subsidiaries within the ethanol production segment were in compliance with their debt covenants as of June 30, 2013.

Agribusiness Segment

Green Plains Grain has a $195.0 million senior secured revolving credit facility with various lenders subject to a borrowing base as defined in the facility. The revolving credit facility matures on October 28, 2013.

The revolving credit facility includes total revolving credit commitments of $195.0 million and an accordion feature whereby amounts available under the facility may be increased by up to $55.0 million of new lender commitments upon agent approval. 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. 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. 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. We expect to extend or refinance the revolving credit facility prior to its maturity date.

Subsidiaries within the agribusiness segment were in compliance with their debt covenants as of June 30, 2013.

Marketing and Distribution Segment

Green Plains Trade has a senior secured asset-based revolving credit facility pursuant to which the lender will loan up to $130.0 million on eligible collateral. This credit facility was increased from $70.0 million in April 2013. 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. At June 30, 2013, Green Plains Trade had $12.1 million in cash that was restricted for repayment of the then outstanding loan balance. Such cash is presented in restricted cash on the consolidated balance sheets. The revolving credit facility expires on April 25, 2016. In addition to other customary covenants, this revolving credit facility contains restrictions on distributions with respect to capital stock, with exceptions (i) for distributions with respect to tax obligations, subject to certain conditions, and (ii) 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.

In June 2013, subsidiaries of the Company executed a New Markets Tax Credits financing transaction. 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 face 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 the recapture or reduction of the income tax credits is remote, and therefore has not established a liability in connection with this guarantee.

Subsidiaries within the marketing and distribution segment were in compliance with their debt covenants as of June 30, 2013.

Corporate Activities

In November 2010, the Company issued $90.0 million of 5.75% Convertible Senior Notes due 2015. The Notes represent senior, unsecured obligations of the Company, with interest payable on May 1 and November 1 of each year. The Notes may be converted into shares of the Company’s common stock and cash in lieu of fractional shares of the common stock based on a conversion rate equal to 69.7788 shares of the common stock per $1,000 principal amount of Notes, which is equal to a conversion price of $14.33 per share. The conversion rate is subject to adjustment upon the occurrence of specified events. The Company may redeem for cash all, but not less than all, of the Notes at any time on and after November 1, 2013, if the last reported sale price of the Company’s common stock equals or exceeds 140% of the applicable conversion price for a specified time period, at a redemption price equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest. Default with respect to any loan in excess of $10.0 million constitutes an event of default under the convertible senior notes, which could result in the convertible senior notes being declared due and payable.

A $27.2 million note payable to a subsidiary of NTR plc, which previously was the Company’s largest shareholder, was paid in full during the first quarter of 2013.

Capitalized Interest

The Company had no capitalized interest during the six months ended June 30, 2013.

Restricted Net Assets

At June 30, 2013, there were approximately $539.0 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.

In April 2013, the Green Plains Bluffton loan and the Green Plains Trade revolving credit facility were both amended. The discussion above has been updated to reflect these amendments.

Earnings Per Share [Abstract]

Earnings Per Share

9.  EARNINGS PER SHARE

Basic earnings per common shares, 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 as-if-converted basis available to common stockholders by the weighted average number of common shares outstanding during the period, adjusted for the dilutive effect of any outstanding dilutive securities. The reconciliations of net income to net income on an as-if-converted basis and basic and diluted earnings per share are as follows (in thousands):

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2013		2012		2013		2012
Basic EPS:

Net income (loss) attributable to Green Plains - basic	$	0.20	$	(0.25)	$	0.28	$	(0.65)
Diluted EPS:

Net income (loss) attributable to Green Plains - diluted	$	0.19	$	(0.25)	$	0.28	$	(0.65)

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, and for the three and six months ended June 30, 2012 were stock-based compensation awards totaling 1.3 and 1.0 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. For the six months ended June 30, 2013, and the three and six months ended June 30, 2012, 6.3 million, 6.4 million and 6.5 million shares, respectively, related to the effect of the convertible debt and stock-based compensation awards, if applicable, were also excluded from the computation of diluted EPS as the inclusion of these shares would have been antidilutive. As consideration for the acquisition of the Lakota and Riga ethanol plants in October 2010, the Company issued warrants for 700,000shares of its stock at a price of $14.00per share exercisable for a period of three years from the closing date. The warrants are excluded from the computations of diluted EPS as the exercise price is greater than the average market price of the Company’s common stock for the three and six month periods ended June 30, 2013 and 2012.

Stock-Based Compensation [Abstract]

Stock-Based Compensation

8.  STOCK-BASED COMPENSATION

The Company has equity incentive plans which reserve a combined total of 3.5million shares of common stock for issuance pursuant to their terms. The plans provide 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 financial statements over the requisite service period on a straight-line basis. All of the Company’s existing share-based compensation awards have been determined to be equity awards.

A summary of stock option activity for the six months ended June 30, 2013 is as follows:

	Shares	Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)

(1) Includes in-the-money options totaling 520,250shares at a weighted-average exercise price of $8.80.

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, 2013:

	Non-Vested Shares and Deferred Stock Units	Weighted-Average Grant-Date Fair Value		Weighted-Average Remaining Vesting Term (in years)
