Fair Value Disclosures [Abstract] |
Fair Value Measurements | 11. Fair Value Measurements The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued payroll and contractor professional pay approximate their fair value based on their short-term nature. The carrying value of the revolving credit facility approximates its fair value. The fair value of the term B loans was $1.1 billion as of March 31, 2019, excluding the $22.3 million of unamortized deferred loan costs (see Note 5. Long-Term Debt) and was determined using Level 1 inputs (quoted prices in active markets for identical assets and liabilities) from the fair value hierarchy. The Company had investments, primarily mutual funds, of $10.1 million and $6.2 million at March 31, 2019 and December 31, 2018, held in a rabbi trust restricted to fund the Company's deferred compensation plan. The fair value of these investments was determined using Level 1 inputs from the fair value hierarchy. These assets are included in other non-current assets. Certain assets and liabilities, such as goodwill and trademarks, 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 the three months ended March 31, 2019 and 2018, no fair value adjustments were required for non-financial assets or liabilities.
