Summary Of Significant Accounti

Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with a maturity of three months or less when purchased to be cash equivalents. Concentration of Credit Risk The Company’s cash balances are maintained in bank deposit accounts which at times may exceed federally-insured limits. The Company has not experienced any losses in such accounts. Revenue Recognition The Company sells ethanol and related products pursuant to marketing agreements. Revenues are recognized when the marketing company has taken title to the product, prices are fixed or determinable and collectability is reasonably assured. The Company’s products are generally shipped FOB loading point, and recorded as a sale upon delivery of the applicable bill of lading. The Company’s ethanol sales are handled through an ethanol purchase agreement (the “ Ethanol Agreement ”) with Bunge North America, Inc. (“ Bunge ”). Syrup and distillers grains (co-products) are sold through a distillers grains agreement (the “ DG Agreement ”) with Bunge, based on market prices. The Company markets and distributes all of the corn oil it produces directly to end users at market prices. Carbon dioxide is sold through a Carbon Dioxide Purchase and Sale Agreement (the “ CO2 Agreemen t”) with Air Products and Chemicals, Inc., formerly known as EPCO Carbon Dioxide Products, Inc. (" Air Products ”). Marketing fees, agency fees, and commissions due to the marketer are calculated separately from the settlement for the sale of the ethanol products and co-products and are included as a component of cost of goods sold. Shipping and handling costs incurred by the Company for the sale of ethanol and co-products are included in cost of goods sold. ASU 2014-09 Revenue from Contracts with Customers (Topic 606) will be effective for SIRE on October 1, 2018. The Company expects to have enhanced disclosures, but does not expect the new standard to have a material impact on the Company's financial statements, as we are currently compliant with the new provisions. Accounts Receivable Accounts receivable are recorded at original invoice amounts less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering customers’ financial condition, credit history and current economic conditions. As of September 30, 2018 and 2017 , management had determined no allowance is necessary. Receivables are written off when deemed uncollectable and recoveries of receivables written off are recorded when received. Risks and Uncertainties The Company's operating and financial performance is largely driven by the prices at which ethanol is sold and the net expense of corn. The price of ethanol is influenced by factors such as supply and demand, weather, government policies and programs, and unleaded gasoline and the petroleum markets with ethanol selling, in general, for less than gasoline at the wholesale level. Excess ethanol supply in the market, in particular, puts downward pressure on the price of ethanol. The Company's largest cost of production is corn. The cost of corn is generally impacted by factors such as supply and demand, weather, government policies and programs. The Company's risk management program is used to protect against the price volatility of these commodities. Investment in Commodities Contracts, Derivative Instruments and Hedging Activities The Company’s operations and cash flows are subject to fluctuations due to changes in commodity prices. The Company is subject to market risk with respect to the price and availability of corn, the principal raw material used to produce ethanol and ethanol by-products. Exposure to commodity price risk results from its dependence on corn in the ethanol production process. In general, rising corn prices result in lower profit margins and, therefore, represent unfavorable market conditions. This is especially true when market conditions do not allow the Company to pass along increased corn costs to customers. The availability and price of corn is subject to wide fluctuations due to unpredictable factors such as weather conditions, farmer planting decisions, governmental policies with respect to agriculture and international trade and global demand and supply. To minimize the risk and the volatility of commodity prices, primarily related to corn and ethanol, the Company uses various derivative instruments, including forward corn, ethanol and distillers grains purchase and sales contracts, over-the-counter and exchange-trade futures and option contracts. When the Company has sufficient working capital available, it enters into derivative contracts to hedge its exposure to price risk related to forecasted corn needs and forward corn purchase contracts. Management has evaluated the Company’s contracts to determine whether the contracts are derivative instruments. Certain contracts that literally meet the definition of a derivative may be exempted from derivative accounting as normal purchases or normal sales. Normal purchases and normal sales are contracts that provide for the purchase or sale of something other than a financial instrument or derivative instrument that will be delivered in quantities expected to be used or sold over a reasonable period in the normal course of business. Gains and losses on contracts that are designated as normal purchases or normal sales contracts are not recognized until quantities are delivered or utilized in production. The Company applies the normal sale exemption to forward contracts relating to ethanol, distillers grains, and corn oil and therefore these forward contracts are not marked to market. As of September 30, 2018 , the Company had no commitments to sell ethanol , but was committed to sell 59 thousand tons of dried distillers grains, 102 thousand tons of wet distillers grains and 3.7 million pounds of corn oil. Corn purchase contracts are treated as derivative financial instruments. Changes in fair value of forward corn contracts, which are marked to market each period, are included in costs of goods sold. As of September 30, 2018 , the Company was committed to purchasing 4.0 million bushels of corn on a forward contract basis resulting in a total commitment of $14.9 million . In addition the Company was committed to purchasing 237.3 thousand bushels of corn using basis contracts. In addition, the Company enters into short-term cash, options and futures contracts as a means of managing exposure to changes in commodity prices. The Company enters into derivative contracts to hedge the exposure to volatile commodity price fluctuations. The Company maintains a risk management strategy that uses derivative instruments to minimize significant, unanticipated earnings fluctuations caused by market volatility. The Company’s specific goal is to protect itself from large moves in commodity costs. All derivatives are designated as non-hedge derivatives and the contracts will be accounted for at fair value. Although the contracts are considered effective economic hedges of specified risks, they are not designated as or accounted for as hedging instruments. Derivatives not designated as hedging instruments along with cash due to brokers at September 30, 2018 and 2017 are as follows: Balance Sheet Classification September 30, 2018 September 30, 2017 in 000's in 000's Futures and option contracts In gain position $ 583 $ 190 In loss position (82 ) (100 ) Cash held by (due to) broker 545 (67 ) Current asset 1,046 23 Forward contracts, corn Current liability 1,567 911 Net futures, options, and forward contracts $ (521 ) $ (888 ) The net realized and unrealized gains and losses on the Company’s derivative contracts for the years ended September 30, 2018 and 2017 consist of the following: Statement of Operations Classification September 30, 2018 September 30, 2017 Net realized and unrealized (gains) losses related to: (in 000's) (in 000's) Forward purchase contracts (corn) Cost of Goods Sold $ 1,894 $ 1,590 Futures and option contracts (corn) Cost of Goods Sold (3,568 ) (1,980 ) Futures and option contracts (ethanol) Revenue — — Inventory Inventory is stated at the lower of average cost or net realizable value. In the valuation of inventories and purchase commitments, net realizable value is defined as estimated selling price in the ordinary course of business less reasonable predictable costs of completion, disposal and transportation. Property and Equipment Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: Buildings 40 Years Process Equipment 10 - 20 Years Office Equipment 3-7 Years Maintenance and repairs are charged to expense as incurred; major improvements are capitalized. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows from operations are less than the carrying value of the asset group. An impairment loss would be measured by the amount by which the carrying value of the asset exceeds the fair value of the asset. Management has determined there were no events or changes in circumstances that required an impairment evaluation during Fiscal 2018 or Fiscal 2017 . Income Taxes The Company has elected to be treated as a partnership for federal and state income tax purposes and generally does not incur income taxes. Instead, the Company’s earnings and losses are included in the income tax returns of the members. Therefore, no provision or liability for federal or state income taxes has been included in these financial statements. Management has evaluated the Company’s tax positions under the Financial Accounting Standards Board issued guidance on accounting for uncertainty in income taxes and concluded that the Company has taken no uncertain tax positions that require adjustment to the financial statements to comply with the provisions of this guidance. Fair value of financial instruments The carrying amounts of cash and cash equivalents, derivative financial instruments, accounts receivable, accounts payable and accrued expenses approximate fair value due to the short term nature of these instruments. The put option liability consists of an agreement between the Company and ICM that contains a conditional obligation to repurchase feature. In accordance with accounting for put options as a liability, the Company calculated the fair value of the put option under Level 3, using a valuation model called the Monte Carlo Simulation. Using this model, the estimated value at September 30, 2018 and 2017 was $5.4 million and $5.7 million , respectively. The carrying amount of the notes payable approximates fair value, as the interest rate is a floating rate. The terms are consistent with those available in the market as of September 30, 2018 and 2017 , using level 3 inputs. Income Per Unit Basic income per unit is calculated by dividing net income by the weighted average units outstanding for each period. Diluted income per unit is adjusted for convertible debt, using the treasury stock method and the put option using the reverse treasury stock method. In Fiscal 2018 , the put option did not impact diluted income per unit as it was anti-dilutive. Basic earnings and diluted per unit data were computed as follows (in thousands except per unit data): Twelve Months Ended September 30, 2018 September 30, 2017 Numerator: Net income (loss) for basic earnings per unit $ (2,137 ) $ 13,445 Change in fair value of put option liability $ (300 ) $ (400 ) Net income (loss) for diluted earnings per unit $ (2,437 ) $ 13,045 Denominator: Weighted average units outstanding - basic 13,327 13,327 Weighted average units outstanding - diluted 13,327 14,394 Income (loss) per unit - basic $ (160.35 ) $ 1,008.85 Income (loss) per unit - diluted $ (160.35 ) $ 906.28 Recently Issued Accounting Pronouncements Revenue Recognition In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes all existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. The new standard is effective for us on October 1, 2018. The Company expects to have enhanced disclosures, but does not expect the new standard to have a material impact on the Company's financial statements.

Fair Value Measurement

Fair Value Disclosures [Abstract]
Fair Value Measurement	Fair Value Measurement Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, the Company used various methods including market, income and cost approaches. Based on these approaches, the Company often utilized certain assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and/or the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated, or generally unobservable inputs. The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Based on the observable inputs used in the valuation techniques, the Company is required to provide the following information according to the fair value hierarchy. The fair value hierarchy ranks the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories: Level 1 - Valuations for assets and liabilities traded in active markets from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 - Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third-party pricing services for identical or similar assets or liabilities. Level 3 - Valuations incorporate certain assumptions and projections in determining the fair value assigned to such assets or liabilities. A description of the valuation methodologies used for instruments measured at fair value, including the general classifications of such instruments pursuant to the valuation hierarchy, is set below. Put Option liability . The put option liability consists of an agreement between the Company and ICM that contains a conditional obligation to repurchase feature. In accordance with accounting for put options as a liability, the Company calculated the fair value of the put option under Level 3, using a valuation model called the Monte Carlo Simulation. Derivative financial statements . Commodity futures and exchange traded options are reported at fair value utilizing Level 1 inputs. For these contracts, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes and live trading levels from the Chicago Mercantile Exchange (“ CME ”) market. Ethanol contracts are reported at fair value utilizing Level 2 inputs from third-party pricing services. Forward purchase contracts are reported at fair value utilizing Level 2 inputs. For these contracts, the Company obtains fair value measurements from local grain terminal values. The fair value measurements consider observable data that may include live trading bids from local elevators and processing plants which are based off the CME market. The following table summarizes financial instruments measured at fair value on a recurring basis as of September 30, 2018 and 2017 , categorized by the level of the valuation inputs within the fair value hierarchy: (dollars in '000s) September 30, 2018 Level 1 Level 2 Level 3 Assets: Derivative financial instruments $ 583 $ — $ — Liabilities: Derivative financial instruments 82 1,567 — Put Option Liability — — 5,400 September 30, 2017 Level 1 Level 2 Level 3 Assets: Derivative financial instruments $ 190 $ — $ — Liabilities: Derivative financial instruments 100 911 — Put Option Liability — — 5,700 The following table summarizes the assumptions used in computing the fair value of the put option subject to fair value: September 30, 2018 September 30, 2017 Expected dividend yield — — Risk-free interest rate 2.57 % 1.34 % Expected volatility 22 % 26 % Expected life (years) 1.25 1.25 Exercise price $ 10,897 $ 10,897 Company unit price $ 5,500 $ 5,670 The following table reflects the activity for liabilities measured at fair value using Level 3 inputs as of September 30, 2018 : September 30, 2018 September 30, 2017 Beginning Balance $ 5,700 $ 6,100 Change in Value (300 ) (400 ) Ending Balance $ 5,400 $ 5,700

Employee Benefits and Share-based Compensation, Noncash [Abstract]
Incentive Compensation	Incentive Compensation The Company has an equity incentive plan which provides that the Board of Directors may make awards of equity appreciation units (“ EAU ”) and equity participation units (“ EPU ”) to employees from time to time, subject to vesting provisions as determined for each award. There are no EAUs outstanding. The EPUs are valued in accordance with the agreement which is based on the book value per unit of the Company. The Company had 65.4 unvested EPUs outstanding under this plan as of September 30, 2018 , which will vest three years from the dates of the awards. During the Fiscal 2018 and 2017 , the Company recorded compensation expense related to this plan of approximately $100,000 and $342,000 , respectively.

Related Party Transaction, Due from (to) Related Party [Abstract]
Related Party Transactions	Related Party Transactions and Major Customers Related Party Transactions Bunge On December 5, 2014, the Company entered into an Amended and Restated Ethanol Purchase Agreement (the “ Ethanol Agreement ”) with Bunge. Under the Ethanol Agreement, the Company has agreed to sell Bunge all of the ethanol produced by the Company, and Bunge has agreed to purchase the same. The Company will pay Bunge a percentage marketing fee for ethanol sold by Bunge, subject to a minimum and maximum annual fee. The initial term of the Ethanol Agreement expires on December 31, 2019, however it will automatically renew for one five-year term unless Bunge provides the Company with notice of election to terminate. The Company has incurred ethanol marketing expenses of $1.5 million in each year for Fiscal 2018 and 2017 , under the Ethanol Agreement. On June 26, 2009, the Company executed a Railcar Agreement with Bunge for the lease of 325 ethanol cars and 300 hopper cars which are used for the delivery and marketing of ethanol and distillers grains. In November 2016, we reduced the number of leased ethanol cars to 323 and in both November 2013 and January 2015 we reduced the number of hopper cars by one for a total of 298 leased hopper cars. Under the Railcar Agreement, the Company leases railcars for terms lasting 120 months and continuing on a month to month basis thereafter. The Railcar Agreement will terminate upon the expiration of all railcar leases. Expenses under this agreement were $4.0 million in each year for Fiscal 2018 and 2017 , net of subleases and accretion, respectively. In November 2016, the Company entered into a sublease for 96 hoppers with Bunge that is set to expire on March 24, 2019. The Company has subleased another 92 hopper cars to unrelated third parties, which expires March 25, 2019. In June 2018, one of the third party customers entered into an assignment agreement for their 52 hopper cars with the Company and Bunge which will be phased in over the fourth quarter, and the start of the first quarter in our fiscal year ending September 30, 2019. SIRE received an up front assignment payment, and the net result will be financially neutral, and the number of side-leased railcars by SIRE remains the same. The Company continues to work with Bunge to determine the need for ethanol and hopper cars in light of current market conditions, and the expected conditions in 2019 and beyond. The Company believes we will be able to fully utilize our fleet of hopper cars in the future, to allow us to cost-effectively ship distillers grains to distant markets, primarily the export markets. On December 5, 2014, the Company and Bunge entered into an Amended and Restated Distiller’s Grain Purchase Agreement (the “ DG Purchase Agreement ”). Under the DG Purchase Agreement, Bunge will purchase all distiller’s grains produced by the Company, and will receive a marketing fee based on the net sale price of distillers grains, subject to a minimum and maximum annual fee. The initial term of the DG Purchase Agreement expires on December 31, 2019 and will automatically renew for one additional five year term unless Bunge provides notice of election to the Company to terminate. The Company has incurred distillers grains marketing expenses of $1.2 million and $1.1 million during Fiscal 2018 and 2017 , respectively. The Company and Bunge also entered into an Amended and Restated Grain Feedstock Agency Agreement on December 5, 2014 (the “ Agency Agreement ”). The Agency Agreement provides that Bunge will procure corn for the Company, the Company will pay Bunge a per bushel fee, subject to a minimum and maximum annual fee. The initial term of the Agency Agreement expires on December 31, 2019 and will automatically renew for one additional five year term unless Bunge provides notice of election to the Company to terminate. Expenses for corn procurement by Bunge were $0.7 million for each year of the fiscal years ended September 30, 2018 and 2017 . The Company has outstanding corn contracts of 116 thousand bushels with a $393 thousand liability as of September 30, 2018 , and 181 thousand bushels with a $620 thousand liability as of September 30, 2017 included in derivative financial instruments liability on the balance sheet. Starting with the 2015 crop year, the Company is using corn containing Syngenta Seeds, Inc.’s proprietary Enogen® technology (“ Enogen Corn ”) for a portion of its ethanol production needs. The Company contracts directly with growers to produce Enogen Corn for sale to the Company. The Company has contracted for 25,500 acres of Enogen corn for Fiscal 2019. Concurrent with the Agency Agreement, the Company and Bunge entered into a Services Agreement regarding corn purchases (the “ Services Agreement ”). Under this agreement, the Company originates all Enogen Corn contracts for its facility and Bunge assists the Company with certain administrative matters related to Enogen Corn, including facilitating delivery to the facility. The Company pays Bunge a per bushel service fee. The initial term of the Services Agreement expires on December 31, 2019 and will automatically renew for one additional five year term unless Bunge provides notice of election to the Company to terminate. Expenses under the Services Agreement are included as part of the Amended and Restated Grain Feedstock Agency Agreement discussed above. ICM In connection with the payoff of the ICM subordinated debt, the Company entered into the SIRE ICM Unit Agreement dated December 17, 2014 (the “ Unit Agreement ”). Under the Unit Agreement, the Company granted ICM the right to sell to the Company its 1,000 Series C and 18 Series A Membership Units (the “ ICM Units ”) commencing anytime during the earliest of several alternative dates and events at the greater of $10,897 per unit or the fair market value (as defined in the agreement) on the date of exercise. The Company reduced expense in Fiscal 2017 by $400 thousand , and in Fiscal 2018 reduced expense by $300 thousand in conjunction with this put right under the Unit Agreement (the "Loss from debt extinguishment" and the "Change in fair value of put option liability" ). See Note 7 Fair Value Measurement, for the terms of this agreement. Major Customers The Company is party to the Ethanol Agreement and the Distillers Grain Purchase Agreement with Bunge for the exclusive marketing, selling, and distributing of all of the ethanol and distillers grains produced by the Company.

The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. The new standard is effective for us on October 1, 2018. The Company expects to have enhanced disclosures, but does not expect the new standard to have a material impact on the Company's financial statements.

Use Of Estimates	Use of EstimatesThe preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from these estimates.
Cash & Cash Equivalents	Cash and Cash EquivalentsThe Company considers all highly liquid investments purchased with a maturity of three months or less when purchased to be cash equivalents.
Concentration Of Credit Risk	Concentration of Credit RiskThe Company’s cash balances are maintained in bank deposit accounts which at times may exceed federally-insured limits.  The Company has not experienced any losses in such accounts.
Revenue Recognition	Revenue Recognition The Company sells ethanol and related products pursuant to marketing agreements. Revenues are recognized when the marketing company has taken title to the product, prices are fixed or determinable and collectability is reasonably assured. The Company’s products are generally shipped FOB loading point, and recorded as a sale upon delivery of the applicable bill of lading. The Company’s ethanol sales are handled through an ethanol purchase agreement (the “ Ethanol Agreement ”) with Bunge North America, Inc. (“ Bunge ”). Syrup and distillers grains (co-products) are sold through a distillers grains agreement (the “ DG Agreement ”) with Bunge, based on market prices. The Company markets and distributes all of the corn oil it produces directly to end users at market prices. Carbon dioxide is sold through a Carbon Dioxide Purchase and Sale Agreement (the “ CO2 Agreemen t”) with Air Products and Chemicals, Inc., formerly known as EPCO Carbon Dioxide Products, Inc. (" Air Products ”). Marketing fees, agency fees, and commissions due to the marketer are calculated separately from the settlement for the sale of the ethanol products and co-products and are included as a component of cost of goods sold. Shipping and handling costs incurred by the Company for the sale of ethanol and co-products are included in cost of goods sold.
Accounts Receivable	Accounts Receivable Accounts receivable are recorded at original invoice amounts less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering customers’ financial condition, credit history and current economic conditions. As of September 30, 2018 and 2017 , management had determined no
Concentration Risk Disclosure [Text Block]	Risks and UncertaintiesThe Company's operating and financial performance is largely driven by the prices at which ethanol is sold and the net expense of corn. The price of ethanol is influenced by factors such as supply and demand, weather, government policies and programs, and unleaded gasoline and the petroleum markets with ethanol selling, in general, for less than gasoline at the wholesale level. Excess ethanol supply in the market, in particular, puts downward pressure on the price of ethanol. The Company's largest cost of production is corn. The cost of corn is generally impacted by factors such as supply and demand, weather, government policies and programs. The Company's risk management program is used to protect against the price volatility of these commodities.
Investment In Commodities Contracts, Derivative Instruments And Hedging Activities	Investment in Commodities Contracts, Derivative Instruments and Hedging Activities The Company’s operations and cash flows are subject to fluctuations due to changes in commodity prices. The Company is subject to market risk with respect to the price and availability of corn, the principal raw material used to produce ethanol and ethanol by-products. Exposure to commodity price risk results from its dependence on corn in the ethanol production process. In general, rising corn prices result in lower profit margins and, therefore, represent unfavorable market conditions. This is especially true when market conditions do not allow the Company to pass along increased corn costs to customers. The availability and price of corn is subject to wide fluctuations due to unpredictable factors such as weather conditions, farmer planting decisions, governmental policies with respect to agriculture and international trade and global demand and supply. To minimize the risk and the volatility of commodity prices, primarily related to corn and ethanol, the Company uses various derivative instruments, including forward corn, ethanol and distillers grains purchase and sales contracts, over-the-counter and exchange-trade futures and option contracts. When the Company has sufficient working capital available, it enters into derivative contracts to hedge its exposure to price risk related to forecasted corn needs and forward corn purchase contracts. Management has evaluated the Company’s contracts to determine whether the contracts are derivative instruments. Certain contracts that literally meet the definition of a derivative may be exempted from derivative accounting as normal purchases or normal sales. Normal purchases and normal sales are contracts that provide for the purchase or sale of something other than a financial instrument or derivative instrument that will be delivered in quantities expected to be used or sold over a reasonable period in the normal course of business. Gains and losses on contracts that are designated as normal purchases or normal sales contracts are not recognized until quantities are delivered or utilized in production. The Company applies the normal sale exemption to forward contracts relating to ethanol, distillers grains, and corn oil and therefore these forward contracts are not marked to market. As of September 30, 2018 , the Company had no commitments to sell ethanol , but was committed to sell 59 thousand tons of dried distillers grains, 102 thousand tons of wet distillers grains and 3.7 million pounds of corn oil. Corn purchase contracts are treated as derivative financial instruments. Changes in fair value of forward corn contracts, which are marked to market each period, are included in costs of goods sold. As of September 30, 2018 , the Company was committed to purchasing 4.0 million bushels of corn on a forward contract basis resulting in a total commitment of $14.9 million . In addition the Company was committed to purchasing 237.3 thousand bushels of corn using basis contracts. In addition, the Company enters into short-term cash, options and futures contracts as a means of managing exposure to changes in commodity prices. The Company enters into derivative contracts to hedge the exposure to volatile commodity price fluctuations. The Company maintains a risk management strategy that uses derivative instruments to minimize significant, unanticipated earnings fluctuations caused by market volatility. The Company’s specific goal is to protect itself from large moves in commodity costs. All derivatives are designated as non-hedge derivatives and the contracts will be accounted for at fair value. Although the contracts are considered effective economic hedges of specified risks, they are not designated as or accounted for as hedging instruments. Derivatives not designated as hedging instruments along with cash due to brokers at September 30, 2018 and 2017 are as follows: Balance Sheet Classification September 30, 2018 September 30, 2017 in 000's in 000's Futures and option contracts In gain position $ 583 $ 190 In loss position (82 ) (100 ) Cash held by (due to) broker 545 (67 ) Current asset 1,046 23 Forward contracts, corn Current liability 1,567 911 Net futures, options, and forward contracts $ (521 ) $ (888 ) The net realized and unrealized gains and losses on the Company’s derivative contracts for the years ended September 30, 2018 and 2017 consist of the following: Statement of Operations Classification September 30, 2018 September 30, 2017 Net realized and unrealized (gains) losses related to: (in 000's) (in 000's) Forward purchase contracts (corn) Cost of Goods Sold $ 1,894 $ 1,590 Futures and option contracts (corn) Cost of Goods Sold (3,568 ) (1,980 ) Futures and option contracts (ethanol) Revenue — —
Inventory	InventoryInventory is stated at the lower of average cost or net realizable value. In the valuation of inventories and purchase commitments, net realizable value is defined as estimated selling price in the ordinary course of business less reasonable predictable costs of completion, disposal and transportation.
Property And Equipment	Property and Equipment Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the following estimated useful lives: Buildings 40 Years Process Equipment 10 - 20 Years Office Equipment 3-7 Years Maintenance and repairs are charged to expense as incurred; major improvements are capitalized. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows from operations are less than the carrying value of the asset group. An impairment loss would be measured by the amount by which the carrying value of the asset exceeds the fair value of the asset. Management has determined there were no events or changes in circumstances that required an impairment evaluation during Fiscal 2018 or Fiscal 2017
Income Taxes	Income Taxes The Company has elected to be treated as a partnership for federal and state income tax purposes and generally does not incur income taxes. Instead, the Company’s earnings and losses are included in the income tax returns of the members. Therefore, no provision or liability for federal or state income taxes has been included in these financial statements.
Net (Loss) Per Unit	Income Per Unit Basic income per unit is calculated by dividing net income by the weighted average units outstanding for each period. Diluted income per unit is adjusted for convertible debt, using the treasury stock method and the put option using the reverse treasury stock method. In Fiscal 2018 , the put option did not impact diluted income per unit as it was anti-dilutive. Basic earnings and diluted per unit data were computed as follows (in thousands except per unit data): Twelve Months Ended September 30, 2018 September 30, 2017 Numerator: Net income (loss) for basic earnings per unit $ (2,137 ) $ 13,445 Change in fair value of put option liability $ (300 ) $ (400 ) Net income (loss) for diluted earnings per unit $ (2,437 ) $ 13,045 Denominator: Weighted average units outstanding - basic 13,327 13,327 Weighted average units outstanding - diluted 13,327 14,394 Income (loss) per unit - basic $ (160.35 ) $ 1,008.85 Income (loss) per unit - diluted $ (160.35 ) $ 906.28
Fair Value Of Financial Instruments	Fair value of financial instruments The carrying amounts of cash and cash equivalents, derivative financial instruments, accounts receivable, accounts payable and accrued expenses approximate fair value due to the short term nature of these instruments. The put option liability consists of an agreement between the Company and ICM that contains a conditional obligation to repurchase feature. In accordance with accounting for put options as a liability, the Company calculated the fair value of the put option under Level 3, using a valuation model called the Monte Carlo Simulation. Using this model, the estimated value at September 30, 2018 and 2017 was $5.4 million and $5.7 million , respectively. The carrying amount of the notes payable approximates fair value, as the interest rate is a floating rate. The terms are consistent with those available in the market as of September 30, 2018 and 2017
