| 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. 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, 2017 and 2016 , 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, 2017 , the Company was committed to sell 7.0 million gallons of ethanol, 84.7 thousand tons of dried distillers grains, 92.3 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, 2017 , the Company was committed to purchasing 2.9 million bushels of corn on a forward contract basis resulting in a total commitment of $10.3 million . In addition the Company was committed to purchasing 691.1 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, 2017 and 2016 are as follows: Balance Sheet Classification September 30, 2017 September 30, 2016 in 000's in 000's Futures and option contracts In gain position $ 190 $ 361 In loss position (100 ) (20 ) Cash (due to) broker (67 ) (253 ) Current asset 23 88 Forward contracts, corn Current liability 911 1,526 Net futures, options, and forward contracts $ (888 ) $ (1,438 ) The net realized and unrealized gains and losses on the Company’s derivative contracts for the years ended September 30, 2017 and 2016 consist of the following: Statement of Operations Classification September 30, 2017 September 30, 2016 Net realized and unrealized (gains) losses related to: (in 000's) (in 000's) Forward purchase contracts (corn) Cost of Goods Sold $ 1,590 $ 6,468 Futures and option contracts (corn) Cost of Goods Sold (1,980 ) (6,008 ) Futures and option contracts (ethanol) Revenue — 429 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 2017 or Fiscal 2016 . 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, 2017 and 2016 was 5.7 million and $6.1 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, 2017 and 2016, 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 2016, 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, 2017 September 30, 2016 Numerator: Net income for basic earnings per unit $ 13,445 $ 5,093 Change in fair value of put option liability $ (400 ) $ — Net income for diluted earnings per unit $ 13,045 $ 5,093 Denominator: Weighted average units outstanding - basic 13,327 13,327 Weighted average units outstanding - diluted 14,394 13,327 Income per unit - basic $ 1,008.85 $ 382.16 Income per unit - diluted $ 906.28 $ 382.16 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 will be 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. Leases In February 2016, FASB issued ASU 2016-02 "Leases” (" ASU 2016-02 "). ASU 2016-02 requires the recognition of lease assets and lease liabilities by lessees for all leases greater than one year in duration and classified as operating leases under previous GAAP. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, and for interim periods within that fiscal year. We will not implement ASU 2016-02 until October 2019, when Fiscal 2020 starts. The Company does not expect the new standard to have a material impact on the Company's financial statements. Interest - Imputation of Interest In April 2015, the Financial Accounting Standards Board issued ASU 2015-03 that simplifies the presentation of debt issuance costs and requires that debt issuance costs related to a recognized debt liability be presented in the statement of financial position as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. This was adopted for the presentation of 2017 financial documents, and we made reclassifications to the 2016 financial statements to conform with the 2017 presentation. There was no impact on financial position or results of operations. |
