Fair Value Disclosures [Abstract] |
Fair Value Disclosures [Text Block] | Note 8. Fair Value Measurements Factors used in determining the fair value of our financial assets and liabilities are summarized into three broad categories:
| ● | Level 1 – quoted prices in active markets for identical securities;
| ● | Level 2 – other significant observable inputs, including quoted prices for similar securities, interest rates, prepayment spreads and credit risk; and
| ● | Level 3 – significant unobservable inputs, including our own assumptions in determining fair value.
The inputs or methodology used for valuing financial assets and liabilities are not necessarily an indication of the risk associated with investing in them. We use the income approach to determine the fair value of our interest rate swap using observable Level 2 market expectations at each measurement date and an income approach to convert estimated future cash flows to a single present value amount (discounted) assuming that participants are motivated, but not compelled, to transact. Level 2 inputs for the swap valuation are limited to quoted prices for similar assets or liabilities in active markets (specifically futures contracts on LIBOR for the first two years) and inputs other than quoted prices that are observable for the asset or liability (specifically LIBOR cash and swap rates and credit risk at commonly quoted intervals). Mid-market pricing is used as a practical expedient for fair value measurements. Key inputs, including the cash rates for very short-term borrowings, futures rates for up to two years and LIBOR swap rates beyond the derivative maturity are used to predict future reset rates to discount those future cash flows to present value at the measurement date. Inputs are collected from Bloomberg on the last market day of the period. The same method is used to determine the rate used to discount the future cash flows. The valuation of the interest rate swap also takes into consideration our own, as well as the counterparty’s, risk of non-performance under the contract. There were no changes to our valuation techniques during the nine-month period ended September 30, 2013. Assets and Liabilities Measured at Fair Value Following are the disclosures related to our assets and (liabilities) that are measured at fair value (in thousands):

See Note 9 for more details regarding our derivative contracts. Fair Value Disclosures for Financial Assets and Liabilities We determined the carrying value of cash equivalents, accounts receivable, trade payables, accrued liabilities and short-term borrowings approximate their fair values because of the short-term nature and current market rates of these instruments. We believe the carrying value of our variable rate debt approximates fair value. We have fixed-rate debt and calculate the estimated fair value of our fixed-rate debt using a discounted cash flow method. Using estimated current interest rates based on a similar risk profile and duration (Level 2), the fixed cash flows are discounted and summed to compute the fair value of the debt. As of September 30, 2013, this debt had maturity dates between November 2016 and May 2031. A summary of the aggregate carrying values and fair values of our long-term fixed-interest rate debt is as follows (in thousands):
|  | September 30, 2013 |  |  | December 31, 2012 |
Carrying value |  | $ | 133,994 |  |  | $ | 130,469 |
Fair value |  |  | 135,010 |  |  |  | 134,688 |

- 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. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 21 -URI http://asc.fasb.org/extlink&oid=28364263&loc=d3e13537-108611 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 10 -URI http://asc.fasb.org/extlink&oid=28364263&loc=d3e13433-108611 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 28 -URI http://asc.fasb.org/extlink&oid=6957238&loc=d3e14064-108612 Reference 4: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 820 -SubTopic 10 -Section 50 -Paragraph 2 -URI http://asc.fasb.org/extlink&oid=25499696&loc=d3e19207-110258 Reference 5: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 30 -URI http://asc.fasb.org/extlink&oid=6957238&loc=d3e14172-108612 Reference 6: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 825 -SubTopic 10 -Section 50 -Paragraph 16 -URI http://asc.fasb.org/extlink&oid=28364263&loc=d3e13504-108611 + Details
