Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Note 3 – Fair Value Measurements We have adopted the rules prescribed under GAAP for our financial assets and liabilities. GAAP includes a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels: Level 1: Inputs are quoted prices in active markets for identical assets or liabilities. Level 2: Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable, and market-corroborated inputs that are derived principally from or corroborated by observable market data. Level 3: Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. We have used financial derivative instruments to manage our overall cash flow exposure to fluctuations in interest rates. We accounted for derivative instruments in accordance with GAAP that requires derivative instruments to be recorded on the balance sheet at fair value. Changes in fair value of derivative instruments must be recognized in earnings unless specific hedge accounting criteria are met, in which case, the gains and losses are included in other comprehensive income rather than in earnings. We had entered into interest rate swaps with our lender, CoBank, ACB, to manage our cash flow exposure to fluctuations in interest rates. These instruments were designated as cash flow hedges and were effective at mitigating the risk of fluctuations on interest rates in the market place. Any gains or losses related to changes in the fair value of these derivatives are accounted for as a component of accumulated other comprehensive income (loss) for as long as the hedge remains effective. The fair value of our interest rate swap agreements is discussed in Note 6 – “Interest Rate Swaps”. The fair value of our swap agreements were determined based on Level 2 inputs. Other Financial Instruments Other Investments - It is difficult to estimate a fair value for equity investments in companies carried on the equity or cost basis due to a lack of quoted market prices. We conducted an evaluation of our investments in all of our companies in connection with the preparation of our audited financial statements at December 31, 2012. We believe the carrying value of our investments is not impaired. Debt – We estimate the fair value of our long-term debt based on the discounted future cash flows we expect to pay using current rates of borrowing for similar types of debt. Fair value of the debt approximates carrying value. Other Financial Instruments - Our financial instruments also include cash equivalents, trade accounts receivable and accounts payable where the current carrying amounts approximate fair market value.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
