Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements The accounting standard for fair value measurements defines fair value, and establishes a market-based framework or hierarchy for measuring fair value. The standard is applicable whenever assets and liabilities are measured at fair value. The fair value hierarchy established in the standard prioritizes the inputs used in valuation techniques into three levels as follows: Level 1 – Observable inputs – quoted prices in active markets for identical assets and liabilities; Level 2 – Observable inputs other than the quoted prices in active markets for identical assets and liabilities – includes quoted prices for similar instruments, quoted prices for identical or similar instruments in inactive markets, and amounts derived from valuation models where all significant inputs are observable in active markets; and Level 3 – Unobservable inputs – includes amounts derived from valuation models where one or more significant inputs are unobservable and require us to develop relevant assumptions. The following table summarizes the financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2018 and December 31, 2017 and the level they fall within the fair value hierarchy (in thousands):
Amounts Recorded at Fair Value |  | Financial Statement Classification |  | Fair Value Hierarchy |  | Fair Value December 31, 2018 |  | Fair Value December 31, 2017
Non-COLI assets held in Deferred Supplemental Compensation Plan |  | Other assets |  | 1 |  | $ | 403 |  |  | $ | 389 |
Interest rate swaps |  | Other current assets |  | 2 |  | $ | 195 |  |  | $ | 294 |
Non-COLI assets held in the deferred supplemental compensation plan consist of equity funds with fair value based on observable inputs such as quoted prices for identical assets in active markets and changes in its fair value are recorded as selling, general and administrative expenses. We account for our interest rate swap agreements under the provisions of ASC 815, Derivatives and Hedging, and have determined that our swap agreements qualify as cash flow hedges. Accordingly, the fair value of the swap agreements, which is an asset recorded in other current assets of approximately $195 thousand and approximately $294 thousand at December 31, 2018 and 2017, respectively. The offset, net of an income tax effect of approximately $49 thousand and $113 thousand is included in accumulated other comprehensive income in the accompanying balance sheets as of December 31, 2018 and 2017, respectively. The amounts paid and received on the swap agreements are recorded in interest expense in the period during which the related floating-rate interest is incurred. We determine the fair value of the swap agreements based on a valuation model using market data inputs.
