Fair Value Measurements [Abstract] |
Fair Value Measurements | (14) 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, 2014 and December 31, 2013 and the level they fall within the fair value hierarchy (in thousands):
Amounts Recorded at Fair Value | Financial Statement Classification | Fair Value Hierarchy |  | December 31, 2014 |  |  | December 31, 2013 |
Non-COLI assets held in DSC Plan | Other assets | Level 1 |  | $ | 253 |  |  | $ | 198 |
Interest rate swaps | Accrued expenses | Level 2 |  | $ | - |  |  | $ | 326 |
Earn-out obligations - current | Current portion of earn-out obligations | Level 3 |  | $ | 9,455 |  |  | $ | - |
Earn-out obligations - long-term | Earn-out obligations | Level 3 |  | $ | - |  |  | $ | 9,062 |
Changes in the fair value of the Non-COLI assets held in the deferred supplemental compensation plan are recorded as selling, general and administrative expenses. Our interest rate swap agreements expired on June 30, 2014. The amounts paid and received on the swap agreements were recorded in interest expense as yield adjustments in the period during which the related floating-rate interest was incurred. We determined the fair value of the swap agreements based on a valuation model using market data inputs. Our acquisition of WBI in 2011 required us to make additional payments to the sellers of up to a total of $40 million over a four-year post-acquisition period ending June 30, 2015 if WBI achieves certain financial performance. WBI's sellers earned approximately $2.7 million, $219 thousand and $7.1 million based on WBI's financial performance for the earn-out years ended June 30, 2014, 2013, and 2012, respectively. Included in earn-out obligations on our December 31, 2014 balance sheet is approximately $9.5 million classified as the current portion of earn-out obligations, which represents our best estimate of the present value. Changes in the fair value of the earn-out obligations are recorded as contract costs in the period of change through settlement. The following table provides a reconciliation of the beginning and ending balance of the earn-out obligations measured at fair value on a recurring basis that used significant unobservable inputs (Level 3).
|  | Current portion |  |  | Long-term portion |  |  | Total |
Balance as of December 31, 2013 |  | $ | - |  |  | $ | 9,062 |  |  | $ | 9,062 |
Earn-out payments |  |  | - |  |  |  | (2,666 | ) |  |  | (2,666 | )
Fair value adjustment included in earnings |  |  | - |  |  |  | 3,059 |  |  |  | 3,059 |
Reclassification from long-term to short-term |  |  | 9,455 |  |  |  | (9,455 | ) |  |  | - |
Balance as of December 31, 2014 |  | $ | 9,455 |  |  | $ | - |  |  | $ | 9,455 |
We utilize the Monte Carlo valuation model for our earn-out obligation. Significant unobservable inputs used to value the contingent consideration include projected earnings before interest, taxes, depreciation and amortization and the discount rate. The model used a discount rate of 7.5% as of December 31, 2014. If a significant increase or decrease in the discount rate occurred in isolation, the result could be a significantly lower or higher fair value measurement of our earn-out obligation.
