Fair Value Measurements-Recurring Basis

In determining fair value, the Company uses various valuation approaches within the fair value measurement framework. Fair value measurements are determined based on the assumptions that market participants would use in pricing an asset or liability. Applicable accounting literature establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The fair value hierarchy is based on observable or unobservable inputs to valuation techniques that are used to measure fair value. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity's pricing based upon its own market assumptions. Applicable accounting literature defines levels within the hierarchy based on the reliability of inputs as follows:


•	Level 1: Inputs are quoted prices in active markets for identical assets or liabilities.


•	Level 2: Inputs are quoted prices for similar assets or liabilities in an active market, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs other than quoted prices that are observable and market-corroborated inputs, which are derived principally from or corroborated by observable market data.


•	Level 3: Inputs that are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.

As of December 31, 2018 and 2017, the Company had no financial assets and liabilities, other than cash and cash equivalents measured at fair value on a recurring basis. The carrying value of cash and cash equivalents approximates their fair value due to the short-term nature of these financial instruments and has been classified as a Level 1.

Nonrecurring Fair Value Measurements

Certain assets are measured at fair value on a nonrecurring basis; that is, the assets are measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). Non-financial assets such as goodwill, intangible assets, and leasehold improvements, equipment land and construction in progress are subsequently measured at fair value when there is an indicator of impairment and recorded at fair value only when impairment is recognized. The Company assesses the impairment of intangible assets annually or whenever events or changes in circumstances indicate that the carrying amount of an intangible asset may not be recoverable. The fair value of its goodwill and intangible assets is not estimated if there is no change in events or circumstances that indicate the carrying amount of an intangible asset may not be recoverable. The purchase price of business acquisitions is primarily allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values on the acquisition dates, with the excess recorded as goodwill. The Company utilizes Level 3 inputs in the determination of the initial fair value using certain assumptions, which are further discussed in Note 2. Acquisition. There were no impairment charges for the years ended December 31, 2018, 2017 and 2016.

Financial Instruments not Measured at Fair Value

The following table presents the carrying amounts and estimated fair values of financial instruments not measured at fair value in the Consolidated Balance Sheets at December 31, 2018 and 2017:



	2018				2017
(millions)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-term borrowings
Credit Facility, net of original discount on borrowings and deferred financing costs	$	371.2	$	371.2	$	151.0	$	151.0
Other obligations	$	15.4	$	15.4	$	2.8	$	2.8

The fair value of the Restated Credit Facility and Other obligations approximates the carrying amount due to variable interest rates and would be classified as a Level 2. See Note 13. Borrowing Arrangements, for further information.

- 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.
