Certain information and disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted as permitted by such rules and regulations. These financial statements and related notes should be read in conjunction with the financial statements and notes thereto included in the Company’s audited financial statements for the year ended October 31, 2012, contained in the Company’s annual report on Form 10-K.   In the opinion of management, the condensed consolidated interim financial statements reflect all adjustments consisting of normal recurring accruals that we consider necessary to present fairly the Company’s results of operations, financial position and cash flows. The results reported in these condensed consolidated interim financial statements should not be regarded as necessarily indicative of results that may be expected for any other quarter or for the fiscal year.   Nature of Business   The Company owns and operates an ethanol plant near Heron Lake, Minnesota with a permitted capacity of approximately 59.2 million gallons.  In addition, the Company produces and sells distillers grains with solubles and corn oil as co-products of ethanol production.   The Company entered into an asset purchase agreement dated January 22, 2013, which provided for the sale of substantially all of the Company’s assets to, and the assumption of certain of the Company’s liabilities by, Guardian Energy Heron Lake, LLC (Guardian). On April 4, 2013, the Company terminated the agreement in accordance with its terms. As a result of terminating the purchase agreement and the Company renegotiating their loan agreements with AgStar Financial Services, PCA (“AgStar”), AgStar required certain principal paydowns by July 31, 2013. The Company raised all the required funds to pay down its debt to AgStar, to provide adequate working capital to operate the Company effectively and to meet AgStar’s requirements.   Pursuant to an asset purchase agreement dated January 3, 2013, the Company’s subsidiary, Lakefield Farmers Elevator, LLC, sold substantially all of its assets consisting of the elevator and grain storage facilities in Lakefield, Minnesota and Wilder, Minnesota to FCA Co-op, a Minnesota cooperative, for approximately $3.7 million plus the purchase price for corn and fuel inventory (the “Elevator Sale”).  The Elevator Sale closed on February 1, 2013.   Principles of Consolidation   The financial statements include the accounts of Heron Lake BioEnergy, LLC and its wholly owned subsidiaries, Lakefield Farmers Elevator, LLC and HLBE Pipeline Company, LLC, collectively, the “Company.”  HLBE Pipeline Company, LLC owns 73% of Agrinatural Gas, LLC (“Agrinatural”). Given the Company’s control over the operations of Agrinatural and its majority voting interest, the Company consolidates the financial statements of Agrinatural with its consolidated financial statements, with the equity and earnings (loss) attributed to the remaining 27% noncontrolling interest identified separately in the accompanying Consolidated Balance Sheets and Statements of Operations. All significant intercompany balances and transactions are eliminated in consolidation.   Noncontrolling Interest   Amounts recorded as noncontrolling interest on the balance sheet relate to the net investment by an unrelated party in Agrinatural. Income and losses are allocated to the members of Agrinatural based on their respective percentage of membership units held. Agrinatural will provide natural gas to the plant with a specified price per MMBTU for an initial term of 10 years, with two renewal options for five year periods.   Accounting Estimates   Management uses estimates and assumptions in preparing these financial statements in accordance with generally accepted accounting principles. Those estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses.  The Company uses estimates and assumptions in accounting for significant matters including, among others, the analysis of impairment of long-lived assets, contingencies and valuation of forward purchase contract commitments and inventory.  The Company periodically reviews estimates and assumptions, and the effects of revisions are reflected in the period in which the revision is made. Actual results could differ from those estimates.   Long-Lived Assets   The Company reviews property, plant and equipment and other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.  If circumstances require a long-lived asset to be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by an asset to the carrying value of the asset.  If the carrying value of the long-lived asset is not recoverable on an undiscounted basis, impairment is recognized to the extent the carrying value exceeds fair value.  Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values and third-party independent appraisals, as considered necessary.   Fair Value of Financial Instruments   Except for those assets and liabilities which are required by authoritative accounting guidance to be recorded at fair value in our balance sheets, the Company has elected not to record any other assets or liabilities at fair value. No events occurred during the periods ended July 31, 2013 or October 31, 2012 that required adjustment to the recognized balances of assets or liabilities, which are recorded at fair value on a nonrecurring basis.   The carrying value of cash and equivalents, restricted cash, restricted certificates of deposit, accounts receivable, accounts payable and accrued liabilities approximates fair value due to the short maturity of these instruments. The fair value of long-term debt has been estimated using discounted cash flow analysis based upon the Company’s current incremental borrowing rates for similar types of financing arrangements. The fair value of outstanding debt will fluctuate with changes in applicable interest rates. Fair value will exceed carrying value when the current market interest rate is lower than the interest rate at which the debt was originally issued. The fair value of a company’s debt is a measure of its current value under present market conditions. It does not impact the financial statements under current accounting rules. The Company believes the carrying amount of the debt approximates the fair value.   Environmental Liabilities   The Company’s operations are subject to environmental laws and regulations adopted by various governmental entities in the jurisdiction in which it operates.  These laws require the Company to investigate and remediate the effects of the release or disposal of materials at its location.  Accordingly, the Company has adopted policies, practices, and procedures in the areas of pollution control, occupational health, and the production, handling, storage and use of hazardous materials to prevent material environmental or other damage, and to limit the financial liability that could result from such events.  Environmental liabilities are recorded when the liability is probable and the costs can be reasonably estimated.   Net Income (Loss) per Unit   Basic net income (loss) per unit is computed by dividing net income (loss) by the weighted average number of members’ units outstanding during the period.  Diluted net income per unit is computed by dividing net income by the weighted average number of members’ units and members’ unit equivalents outstanding during the period. </div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for the general note to the financial statements for the reporting entity which may include, descriptions of the basis of presentation, business description, significant accounting policies, consolidations, reclassifications, new pronouncements not yet adopted and changes in accounting principles.No definition available.false0SUMMARY OF SIGNIFICANT ACCOUNTING POLICIESfalseSUMMARY OF SIGNIFICANT ACCOUNTING POLICIESUnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.heronlakebioenergy.com/role/DisclosureSummaryOfSignificantAccountingPolicies12
