Fair Value Disclosures [Text Block] | Note 7. 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, 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 estimate the value of our equity-method investment, which is recorded at fair value on a non-recurring basis, based on a market valuation approach. We use prices and other relevant information generated primarily by recent market transactions involving similar or comparable assets. Because these valuations contain unobservable inputs, we classified the measurement of fair value of our equity-method investment as Level 3. We estimate the value of other long-lived assets that are recorded at fair value on a non-recurring basis based on a market valuation approach. We use prices and other relevant information generated primarily by recent market transactions involving similar or comparable assets, as well as our historical experience in divestitures, acquisitions and real estate transactions. Additionally, we may use a cost valuation approach to value long-lived assets when a market valuation approach is unavailable. Under this approach, we determine the cost to replace the service capacity of an asset, adjusted for physical and economic obsolescence. When available, we use valuation inputs from independent valuation experts, such as real estate appraisers and brokers, to corroborate our estimates of fair value. Real estate appraisers’ and brokers’ valuations are typically developed using one or more valuation techniques including market, income and replacement cost approaches. Because these valuations contain unobservable inputs, we classified the measurement of fair value of long-lived assets as Level 3. There were no changes to our valuation techniques during the three-month period ended March 31, 2016. Assets and Liabilities Measured at Fair Value Following are the disclosures related to our assets that are measured at fair value (in thousands):
Fair Value at March 31, 2016 |  | Level 1 |  |  | Level 2 |  |  | Level 3 |
Measured on a non-recurring basis: |  |  |  |  |  |  |  |  |  |  |  |
Equity-method investment |  | $ | — |  |  | $ | — |  |  | $ | 16,721 |
Fair Value at December 31, 2015 |  | Level 1 |  |  | Level 2 |  |  | Level 3 |

Certain buildings and improvements |  | $ | — |  |  | $ | — |  |  | $ | 6,559 |
Based on operating losses recognized by the equity-method investment, we determined that an impairment of our investment had occurred. Accordingly, we performed a fair value calculation for this investment and determined that a $3.5 million and a $4.1 million impairment, respectively, was required to be recorded as asset impairments in our Consolidated Statements of Operations for the three months ended March 31, 2016 and 2015, respectively. See Note 9. 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 nature of their terms 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 methodology. 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 March 31, 2016, this debt had maturity dates between May 1, 2018 and October 1, 2034. A summary of the aggregate carrying values and fair values of our long-term fixed interest rate debt is as follows (in thousands):
|  | March 31, 2016 |  |  | December 31, 2015 |
Carrying value |  | $ | 290,008 |  |  | $ | 297,463 |
Fair value |  |  | 284,075 |  |  |  | 296,961 |

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 820 -SubTopic 10 -Section 50 -Paragraph 2 -URI http://asc.fasb.org/extlink&oid=66048111&loc=d3e19207-110258 Reference 2: 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 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 825 -SubTopic 10 -Section 50 -Paragraph 21 -URI http://asc.fasb.org/extlink&oid=73719730&loc=d3e13537-108611 Reference 5: 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=73719730&loc=d3e13504-108611 Reference 6: 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=73719730&loc=d3e13433-108611 + Details
