The Revolving Term Loan will be used by the Company to optimize its cash management.  The additional equity raised was used to improve working capital availability by paying down the Revolving Term Loan and meeting the required $5 million payment obligation by July 31, 2013. The Company’s Board of Governors loaned the Company $1.4 million in convertible secured debt, which was used to bring the previous AgStar loans up to date.   In addition, the Company is expecting to raise approximately $3.6 million, subsequent to July 31, 2013, in convertible secured debt, which will be released from escrow as described in Note 8.   While the Company believes these changes will improve the operating performance of the plant, provide additional working capital, and reduce the effects on our plant of volatility in the industry, it is not yet certain as to whether these efforts and changes will be successful. </div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure of the entity's ability to continue as a going concern for a reasonable period of time (generally a year from the balance sheet date).No definition available.false0GOING CONCERNfalseGOING CONCERNUnKnownUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.heronlakebioenergy.com/role/DisclosureGoingConcern12
