Fair Value Disclosures [Abstract] |
Fair Value Measurements | Fair Value Measurements Fair value is an exit price representing the expected amount that an entity would receive to sell an asset or pay to transfer a liability in an orderly transaction with market participants at the measurement date. We followed consistent methods and assumptions to estimate fair values as more fully described in the 2018 Annual Report. Our financial instruments that are subject to fair value disclosure consist of cash and cash equivalents, accounts receivable, accounts payable, derivatives, and long-term debt. As of June 30, 2019, the carrying values of these financial instruments approximated fair value. The fair value of floating-rate debt approximates the carrying amount because the interest rates paid are based on short-term maturities. The fair value of our outstanding fixed-rate debt included in the “International lines of credit and other loans” line item within Note 9 to these Notes to Condensed Consolidated Financial Statements was $9.5 million and $10.4 million as of June 30, 2019 and December 31, 2018, respectively. These fair values represent Level 2 under the three-tier hierarchy described above. The book value of our outstanding fixed-rate debt included in the “International lines of credit and other loans” line item within Note 9 to these Notes to Condensed Consolidated Financial Statements was $9.4 million and $9.8 million as of June 30, 2019 and December 31, 2018, respectively. Recurring Fair Value Measurements Fair value principles prioritize valuation inputs across three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the assumptions used to measure assets and liabilities at fair value. An asset or liability’s classification within the various levels is determined based on the lowest level input that is significant to the fair value measurement. We manage our exposure to fluctuations in interest rates using a mix of fixed and variable rate debt. On February 8, 2019, we entered into a $700.0 million fixed-rate interest rate swap agreement that changed the LIBOR-based portion of the interest rate on a portion of our variable rate debt to a fixed rate of 2.4575% (the “interest rate swap”). The term of the interest rate swap is from the effective date of February 12, 2019, through the termination date of October 19, 2022 (the “interest rate swap term”). The interest rate swap effectively mitigates our exposures to the risks and variability of changes in LIBOR. The notional amount of the interest rate swap will decrease over the interest rate swap term as follows:
|  | Notional Amount
February 12, 2019 - December 30, 2020 |  | $ | 700,000 |
December 31, 2020 - December 30, 2021 |  | 466,667 |
December 31, 2021 - October 19, 2022 |  | 233,333 |
The objective of the interest rate swap is to eliminate the variability of cash flows in interest payments on the first $700.0 million of variable rate debt attributable to changes in benchmark one-month LIBOR interest rates. The hedged risk is the interest rate risk exposure to changes in interest payments, attributable to changes in benchmark one-month LIBOR interest rates over the interest rate swap term. If one-month LIBOR is greater than the minimum percentage under the Senior Secured Term Loan, the changes in cash flows of the interest rate swap are expected to exactly offset changes in cash flows of the variable rate debt. The interest rate swap is designated as a cash flow hedge. As of June 30, 2019, we reported a $10.8 million loss, net of tax, in accumulated other comprehensive income related to the interest rate swap. The following shows the liabilities measured at fair value on a recurring basis for the interest rate swap as of June 30, 2019.

Description |  | Quoted Prices in Active Markets for Identical Assets (Level 1) |  | Significant Other Observable Inputs (Level 2) |  | Significant Unobservable Inputs (Level 3)
Derivative liability - other current liabilities |  | $ | — |  |  | $ | 4,244 |  |  | $ | — |
Derivative liability - other non-current liabilities |  | — |  |  | 9,671 |  |  | — |
Total |  | $ | — |  |  | $ | 13,915 |  |  | $ | — |
The inputs for determining fair value of the interest rate swap are classified as Level 2 inputs. Level 2 fair value is based on estimates using standard pricing models. These standard pricing models use inputs which are derived from or corroborated by observable market data such as interest rate yield curves, index forward curves, discount curves, and volatility surfaces. Counterparty to this derivative contract is a highly rated financial institution which we believe carries only a minimal risk of nonperformance. As of December 31, 2018, we had no interest rate swap agreements or other derivative financial instruments outstanding.

- Definition The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information. + References Reference 1: http://www.xbrl.org/2003/role/disclosureRef -Publisher FASB -Name Accounting Standards Codification -Topic 820 -SubTopic 10 -Section 50 -Paragraph 2 -URI http://asc.fasb.org/extlink&oid=117815213&loc=d3e19207-110258 + Details
