Revolving Credit Facilities and Long-Term Obligations [Abstract]
Revolving Credit Facilities	6. Revolving Credit Facilities Effective May 31, 2011, the Company and Farm Credit West, PCA (FCW), entered into a Term Revolving Credit Agreement (Revolving Agreement). Under the terms of the Revolving Agreement, we are advanced funds for working capital purposes, the purchase and installation of capital items, as well as other corporate needs of the Company. Total credit available under the borrowing agreement is $40 million, up from $30 million, and expires on February 1, 2016. This increase was at our request and not due to any immediate cash flows needs. Effective September 30, 2011, the Company and Bank of America, N.A. (BoA), entered into an agreement, Amendment No. 4 to Loan Agreement (the Agreement), which amended our existing credit facility with BoA. Under the terms of the Agreement, we are advanced funds primarily for working capital purposes. Total credit available under the borrowing agreement is now $25 million, up from $15 million and now expires on February 1, 2016. This increase was at our request and not due to any immediate cash flows needs. Under the terms of these agreements, we are advanced funds for both working capital and long-term productive asset purchases. Total credit available under these combined borrowing agreements was $65 million, with a weighted-average interest rate of 1.8% and 1.6% at October 31, 2012 and 2011. Under these credit facilities, we had $20.2 million and $17.9 million outstanding as October 31, 2012 and 2011. These credit facilities contain various financial covenants, the most significant relating to Tangible Net Worth (as defined), Current Ratio (as defined), and Fixed Charge Coverage Ratio (as defined). We were in compliance with all such covenants at October 31, 2012.
