Fair Value Disclosures [Abstract] |
Fair Value Measurements | NOTE 9. — FAIR VALUE MEASUREMENTS Debt Instruments As of June 30, 2018 and December 31, 2017, the carrying value of the borrowings under the Restated Credit Agreement approximated fair value. As of June 30, 2018 and December 31, 2017, the fair value of the borrowings under senior unsecured notes was $331,800,000 and $233,500,000, respectively. The fair value of the borrowings outstanding as of June 30, 2018 and December 31, 2017, was determined using a discounted cash flow technique that incorporates a market interest yield curve with adjustments for duration, risk profile and borrowings outstanding, which are based on unobservable inputs within Level 3 of the Fair Value Hierarchy. Supplemental Retirement Plan We have mutual fund assets that are measured at fair value on a recurring basis using Level 1 inputs. We have a Supplemental Retirement Plan for executives. The amounts held in trust under the Supplemental Retirement Plan using Level 2 inputs may be used to satisfy claims of general creditors in the event of our or any of our subsidiaries’ bankruptcy. We have liability to the executives participating in the Supplemental Retirement Plan for the participant account balances equal to the aggregate of the amount invested at the executives’ direction and the income earned in such mutual funds. The following summarizes as of June 30, 2018, our assets and liabilities measured at fair value on a recurring basis by level within the Fair Value Hierarchy (in thousands):
|  | Level 1 |  |  | Level 2 |  |  | Level 3 |  |  | Total |
Assets: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |

Real Estate Assets We have certain real estate assets that are measured at fair value on a non-recurring basis using Level 3 inputs as of June 30, 2018 and December 31, 2017, of $2,217,000 and $2,785,000, respectively, where impairment charges have been recorded. Due to the subjectivity inherent in the internal valuation techniques used in estimating fair value, the amounts realized from the sale of such assets may vary significantly from these estimates.
