Nature of Business and Significant Accounting Policies [Abstract]  
Business Description and Accounting Policies
Nature of Business and Significant Accounting Policies
 
Principal business activity:  Lincolnway Energy, LLC (the Company), located in Nevada, Iowa, was formed in May 2004 to pool investors to build a 50 million gallon annual production dry mill corn-based ethanol plant.  The Company began making sales on May 30, 2006 and became operational during the quarter ended June 30, 2006. The Company is directly influenced by commodity markets and the agricultural and energy industries and, accordingly, its results of operations and financial condition may be significantly affected by cyclical market trends and the regulatory, political and economic conditions in these industries.

A summary of significant accounting policies follows:

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 those estimates.

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.

Cash and cash equivalents:  For the purposes of reporting the statement of cash flows, the Company includes as cash equivalents all cash accounts and highly liquid debt instruments which are not subject to withdrawal restrictions or penalties.  Certificates of deposit are considered investments as all have been purchased with maturities in excess of ninety days.  Although the Company maintains its cash accounts in one bank, the Company believes it is not exposed to any significant credit risk on cash and cash equivalents.  The Company has repurchase agreements with one bank, which totaled approximately $2,337,771 at September 30, 2013.  In accordance with the terms of the repurchase agreements, the Company does not take possession of the related securities.  The Company’s agreements also contain provisions to ensure that the market value of the underlying assets remain sufficient to protect the Company in the event of default by the banks by requiring that the underlying securities have a total market value of at least 100% of the bank’s total obligations under the agreements.

Trade accounts receivable:  Trade 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.  Receivables are written off when deemed uncollectible.  Recoveries of receivables written off are recorded when received.  A receivable is considered past due if any portion of the receivable is outstanding more than 90 days.

Deferred revenue: Deferred revenue represents fees received under a service agreement in advance of services being performed. The related revenue is deferred and recognized as the services are performed over the term of the contract.

Inventories:  Inventories are stated at the lower of cost or market using the first-in, first-out method.  In the valuation of inventories and purchase and sale commitments, market is based on current replacement values except that it does not exceed net realizable values and is not less than net realizable values reduced by allowances for approximate normal profit margin.

Financing costs:  Financing costs are recorded at cost and include expenditures directly related to securing debt financing.  The Company is amortizing these costs using the effective interest method over the term of the agreement.  The financing costs are included in interest expense on the statement of operations.

Property and equipment:  Property and equipment is stated at cost.  Construction in progress is comprised of costs related to the projects that are not completed.  Depreciation is computed using the straight-line method over the following estimated useful lives:

 
Years
Land improvements
20
Buildings and improvements
40
Plant and process equipment
5 – 20
Office furniture and equipment
3 – 7


Maintenance and repairs are expensed as incurred; major improvements and betterments are capitalized.  

Investments:  The Company has investments in financial service cooperatives.  These investments are carried at cost including allocated retained earnings of the cooperatives.

Derivative financial instruments:  The Company periodically enters into derivative contracts to hedge the Company’s exposure to price risk related to forecasted corn needs, forward corn purchase contracts and ethanol sales.  The Company does not typically enter into derivative instruments other than for hedging purposes.  All the derivative contracts are recognized on the balance sheet at their fair market value.  Although the Company believes its derivative positions are economic hedges, none have been designated as a hedge for accounting purposes.   Accordingly, any realized or unrealized gain or loss related to corn derivatives is recorded in the statement of operations as a component of cost of goods sold.  Any realized or unrealized gain or loss related to ethanol derivative instruments is recorded in the statement of operations as a component of revenue. The Company reports all contracts with the same counter party on a net basis on the balance sheet.

Deposit:  The Internal Revenue Service (under Section 7519) requires partnerships that elect a fiscal year over a calendar year to make a deposit each year.  The deposit is 25% of annual taxable net income, multiplied by the tax rate of 36% for the reporting fiscal year.

Revenue recognition:  Revenue from the sale of the Company’s ethanol and distillers grains is recognized at the time title and all risks of ownership transfer to the customers.  This generally occurs upon the loading of the product.  For ethanol, title passes at the time the product crosses the loading flange in either a railcar or truck.  For distiller’s grain, title passes upon the loading into trucks.  For railcar shipments, this takes place when the railcar is filled and the marketer receives written notice that they have been loaded and are available for billing.  Shipping and handling costs incurred by the Company for the sale of distiller’s grain are included in costs of goods sold. Ethanol revenue is reported free on board (FOB) and all shipping and handling costs are incurred by the ethanol marketer. For the years 2012 and 2011 freight for ethanol was included in costs of goods sold. Commissions for the marketing and sale of ethanol and distiller grains are included in costs of goods sold.

Revenue by product is as follows:

Income taxes:  The Company is organized 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 material tax positions and determined there were no uncertain tax positions that require adjustment to the financial statements. The Company does not currently anticipate significant changes in its uncertain tax positions over the next 12 months. Generally, the Company remains subject to income tax examinations by U.S. federal or state tax authorities for fiscal years 2010 and thereafter.

Earnings per unit:  Basic and diluted earnings per unit have been computed on the basis of the weighted average number of units outstanding during each period presented.

Fair value of financial instruments:  The carrying amounts of cash and cash equivalents, derivative financial instruments, trade and other accounts receivable, restricted cash, accounts payable and accrued expenses approximate fair value.  The carrying amount of long-term debt approximates fair value because the interest rates are based on current rates offered to the Company for debt with similar terms and maturities.

Lease Commitments
 
The Company entered into a lease agreement with an unrelated third party to lease 90 hopper rail cars for the purpose of transporting distiller’s grain.  The five-year term of the lease commenced March 2006 and ended March 2011.  On March 26, 2011 the Company extended this lease with a rider. The rider calls for monthly payments of $56,700 plus applicable taxes.  There was also an additional usage rental of 2.5 cents per mile for each car that exceeds 30,000 miles.  The amendment that was made to the lease agreement on June 19, 2007, allowed the Company to purchase a certificate of deposit for $351,000 in lieu of the letter of credit that was required as partial security for the Company’s obligation under the lease.  The Company has classified this certificate of deposit as restricted cash in other assets. The lease term on the rider is for three years commencing March 2011 and expiring March 2014. In conjunction with a change in the Company’s ethanol marketer, on September 21, 2009, the Company was assigned a lease that was previously between the Company’s previous ethanol marketer and an unrelated third party.  The lease includes 100 tank rail cars for the purpose of transporting ethanol.  The lease calls for monthly payments of $52,500 plus applicable taxes, beginning October 1, 2009.  There is also an additional usage rental of 3 cents per mile for each car that exceeds 35,000 miles.  The lease has an expiration date of September 2016.
 
On February 2, 2010, the Company entered into a lease agreement with an unrelated third party to lease an additional 30 ethanol tank rail cars.  The one-year term of the lease ended on February 2011.  On March 8, 2011 the Company extended this lease with two riders for 15 railcars each. Each rider calls for monthly payments of $9,750 plus applicable taxes. There was also an additional usage rental of 3 cents per mile for each car that exceeds 30,000 miles.  The lease term on the riders is for three years commencing March 2011 and expiring March 2014.

Risk Management [Abstract]  
Derivative Instruments and Hedging Activities Disclosure
Risk Management
 
The Company’s activities expose it to a variety of market risks, including the effects of changes in commodity prices.  These financial exposures are monitored and managed by the Company as an integral part of its overall risk management program.  The Company’s risk management program focuses on the unpredictability of commodity markets and seeks to reduce the potentially adverse effects that the volatility of these markets may have on its operating results.

The Company maintains a risk management strategy that uses derivative instruments to minimize significant, unanticipated earnings fluctuations caused by market fluctuations.  The Company’s specific goal is to protect the Company from large moves in the commodity costs.

To reduce price risk caused by market fluctuations, the Company generally follows a policy of using exchange-traded futures and options contracts to minimize its net position of merchandisable agricultural commodity inventories and forward purchases and sales contracts.

Exchange traded futures and options contracts are designated as non-hedge derivatives and are valued at market price with changes in market price recorded in operating income through cost of goods sold for corn derivatives and through revenue for ethanol derivatives.
 
Derivatives not designated as hedging instruments as of September 30, 2013 and 2012 are as follows:

Fair Value Disclosures [Abstract]  
Fair Value Measurements
Fair Value Measurements
 
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 uses various methods including market, income and cost approaches.  Based on these approaches, the Company often utilizes 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 observability of the 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 2Valuations 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 3Valuations 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 classification of such instruments pursuant to the valuation hierarchy, is set forth below.  These valuation methodologies were applied to all of the Company’s financial assets and financial liabilities carried at fair value.
 
Derivative financial instruments:  Commodity futures and exchange-traded commodity options contracts 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 CME and NYMEX markets.  The fair value measurements consider observable data that may include dealer quotes and live trading levels from the over-the-counter markets.

The following table summarizes the financial assets and liabilities measured at fair value on a recurring basis as of September 30, 2013 and 2012, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

Nature of Business and Significant Accounting Policies (Policies)
12 Months Ended
Sep. 30, 2013
Nature of Business and Significant Accounting Policies [Abstract]  
Use of estimates
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 those estimates.
Concentration of credit risk
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.
Cash and cash equivalents
Cash and cash equivalents:  For the purposes of reporting the statement of cash flows, the Company includes as cash equivalents all cash accounts and highly liquid debt instruments which are not subject to withdrawal restrictions or penalties.  Certificates of deposit are considered investments as all have been purchased with maturities in excess of ninety days.  Although the Company maintains its cash accounts in one bank, the Company believes it is not exposed to any significant credit risk on cash and cash equivalents.  The Company has repurchase agreements with one bank, which totaled approximately $2,337,771 at September 30, 2013.  In accordance with the terms of the repurchase agreements, the Company does not take possession of the related securities.  The Company’s agreements also contain provisions to ensure that the market value of the underlying assets remain sufficient to protect the Company in the event of default by the banks by requiring that the underlying securities have a total market value of at least 100% of the bank’s total obligations under the agreements.
Trade accounts receivable
Trade accounts receivable:  Trade 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.  Receivables are written off when deemed uncollectible.  Recoveries of receivables written off are recorded when received.  A receivable is considered past due if any portion of the receivable is outstanding more than 90 days.
Inventories
Inventories:  Inventories are stated at the lower of cost or market using the first-in, first-out method.  In the valuation of inventories and purchase and sale commitments, market is based on current replacement values except that it does not exceed net realizable values and is not less than net realizable values reduced by allowances for approximate normal profit margin.
Financing costs
Financing costs:  Financing costs are recorded at cost and include expenditures directly related to securing debt financing.  The Company is amortizing these costs using the effective interest method over the term of the agreement.  The financing costs are included in interest expense on the statement of operations.
Property and equipment
Property and equipment:  Property and equipment is stated at cost.  Construction in progress is comprised of costs related to the projects that are not completed.  Depreciation is computed using the straight-line method over the following estimated useful lives:

 
Years
Land improvements
20
Buildings and improvements
40
Plant and process equipment
5 – 20
Office furniture and equipment
3 – 7


Maintenance and repairs are expensed as incurred; major improvements and betterments are capitalized.  
Investments
Investments:  The Company has investments in financial service cooperatives.  These investments are carried at cost including allocated retained earnings of the cooperatives.
Derivative financial instruments
Derivative financial instruments:  The Company periodically enters into derivative contracts to hedge the Company’s exposure to price risk related to forecasted corn needs, forward corn purchase contracts and ethanol sales.  The Company does not typically enter into derivative instruments other than for hedging purposes.  All the derivative contracts are recognized on the balance sheet at their fair market value.  Although the Company believes its derivative positions are economic hedges, none have been designated as a hedge for accounting purposes.   Accordingly, any realized or unrealized gain or loss related to corn derivatives is recorded in the statement of operations as a component of cost of goods sold.  Any realized or unrealized gain or loss related to ethanol derivative instruments is recorded in the statement of operations as a component of revenue. The Company reports all contracts with the same counter party on a net basis on the balance sheet.
Deposit
Deposit:  The Internal Revenue Service (under Section 7519) requires partnerships that elect a fiscal year over a calendar year to make a deposit each year.  The deposit is 25% of annual taxable net income, multiplied by the tax rate of 36% for the reporting fiscal year.
Revenue recognition
Revenue recognition:  Revenue from the sale of the Company’s ethanol and distillers grains is recognized at the time title and all risks of ownership transfer to the customers.  This generally occurs upon the loading of the product.  For ethanol, title passes at the time the product crosses the loading flange in either a railcar or truck.  For distiller’s grain, title passes upon the loading into trucks.  For railcar shipments, this takes place when the railcar is filled and the marketer receives written notice that they have been loaded and are available for billing.  Shipping and handling costs incurred by the Company for the sale of distiller’s grain are included in costs of goods sold. Ethanol revenue is reported free on board (FOB) and all shipping and handling costs are incurred by the ethanol marketer. For the years 2012 and 2011 freight for ethanol was included in costs of goods sold. Commissions for the marketing and sale of ethanol and distiller grains are included in costs of goods sold.
Income taxes
Income taxes:  The Company is organized 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 material tax positions and determined there were no uncertain tax positions that require adjustment to the financial statements. The Company does not currently anticipate significant changes in its uncertain tax positions over the next 12 months. Generally, the Company remains subject to income tax examinations by U.S. federal or state tax authorities for fiscal years 2010 and thereafter.
Earnings per unit
Earnings per unit:  Basic and diluted earnings per unit have been computed on the basis of the weighted average number of units outstanding during each period presented.
Fair value of financial instruments
Fair value of financial instruments:  The carrying amounts of cash and cash equivalents, derivative financial instruments, trade and other accounts receivable, restricted cash, accounts payable and accrued expenses approximate fair value.  The carrying amount of long-term debt approximates fair value because the interest rates are based on current rates offered to the Company for debt with similar terms and maturities.
