Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements The recorded values of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair value based on their short-term nature. Long-term debt recorded in the Company’s Consolidated Balance Sheets at December 31, 2015 was $755.5 million (net of $18.5 million of unamortized deferred loan costs, see "Note 6. Long-Term Debt"). The fair value of the long-term debt at that same date was $779.8 million as determined using the quoted price technique, based on Level 2 inputs (significant observable inputs other than quoted prices for identical assets in active markets) from the fair value hierarchy, and included the yields of comparable companies with similar credit characteristics. Related to its acquisitions, at December 31, 2015, the Company had obligations to pay contingent consideration in cash if certain performance targets were met. The fair value of this contingent consideration was determined using an expected present value technique. Expected cash flows were determined using the probability-weighted average of possible outcomes that would occur should certain financial metrics be reached. There is no market data available to use in valuing the contingent consideration, therefore, the Company developed its own assumptions related to the future financial performance of the businesses to evaluate the fair value of these liabilities. As such, the contingent consideration is classified within Level 3 inputs (unobservable inputs) from the fair value hierarchy. The fair value of the liability for contingent consideration is established at the time of the acquisition and finalized by the end of the measurement period. Its fair value is then remeasured on a recurring basis with changes due to the accretion of the present value discount, recorded in interest expense and changes related to new developments in expected performance, recorded in SG&A. In 2015 there was discount accretion totaling $1.4 million and expense of $2.8 million related to an increase in the obligation. The performance period for these contingent consideration arrangements ended on December 31, 2015; the liability was estimated to be $21.0 million and is included in other current liabilities. At December 31, 2014, contingent consideration was estimated to be $3.0 million and was included in other long-term liabilities (refer to "Note 4. Acquisitions" for further information). The reconciliation of contingent consideration liability measured and carried at fair value on a recurring basis with the use of significant unobservable inputs (Level 3) are as follows (in thousands):

Certain assets and liabilities, such as goodwill, are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (e.g., when there is evidence of impairment). For 2015 and 2014, no fair value adjustments were required for non-financial assets or liabilities.
