Fair Value Measurement

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.

The following table sets forth the Company's financial assets and liabilities measured at fair value on a recurring basis and the basis of measurement at December 31, 2015 and 2014:

Interest Rate Swap

The Company seeks to minimize risks from interest rate fluctuations through the use of interest rate swap contracts and hedge only exposures in the ordinary course of business. Interest rate swaps are used to manage interest rate risk associated with our floating rate debt. The Company accounts for its derivative instruments at fair value provided it meets certain documentary and analytical requirements to qualify for hedge accounting treatment. Hedge accounting creates the potential for a Consolidated Statements of Income match between the changes in fair values of derivatives and the changes in cost of the associated underlying transactions, in this case interest expense. Derivatives held by us are designated as hedges of specific exposures at inception, with an expectation that changes in the fair value will essentially offset the change in the underlying exposure. Discontinuance of hedge accounting is required whenever it is subsequently determined that an underlying transaction is not going to occur, with any gains or losses recognized in the Consolidated Statements of Income at such time, with any subsequent changes in fair value recognized currently in earnings. Fair values of derivatives are determined based on quoted prices for similar contracts. The effective portion of the change in fair value of the interest rate swap is reported in accumulated other comprehensive income, a component of stockholders' equity, and is being recognized as an adjustment to interest expense or other (expense) income, respectively, over the same period the related expenses are recognized in earnings. Ineffectiveness would occur when changes in the market value of the hedged transactions are not completely offset by changes in the market value of the derivative and those related gains and losses on derivatives representing hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized currently in earnings when incurred. No ineffectiveness was recognized during 2015, 2014 or 2013.

Contingent Consideration Receivable

During the third quarter of 2015, certain assets, which met the definition of a business, were sold to a third-party in an arms-length transaction (see also Note 1. Significant Accounting Policies and Practices for further detail on the sale of the business). Under the sales agreement, 40% of the sale proceeds from the buyer is contingent in nature and scheduled to be received by the Company in February 2017, or eighteen months from the date of the transaction. The contingent consideration amount expected to be received by the Company is based on the financial and operational performance of the business sold. The significant inputs used to derive the Level 3 fair value contingent consideration receivable is the probability of reaching certain revenue growth of the business and retention of current customers over the eighteen month period. The fair value of the contingent consideration receivable for the year ended December 31, 2015 was $0.5 million.

Contingent Consideration Obligation

The significant inputs used to derive the fair value of the contingent consideration obligation include financial forecasts of future operating results, the probability of reaching the forecast and the associated discount rate. The contingent acquisition obligation remaining for the year ended December 31, 2015 was not significant.

The following table provides a reconciliation of the beginning and ending balances for the contingent consideration obligation measured at fair value using significant unobservable inputs (Level 3):



(millions)	Due to Seller
Balance at December 31, 2012	$	(3.3	)
Increase related to new acquisitions	—
Payment of contingent consideration	0.9
Change in fair value	0.9
Balance at December 31, 2013	(1.5		)
Increase related to new acquisitions	—
Payment of contingent consideration	1.8
Change in fair value	(0.5		)
Balance at December 31, 2014	(0.3		)
Increase related to new acquisitions	—
Payment of contingent consideration	0.1
Change in fair value	0.2
Balance at December 31, 2015	$	—

Note: Amounts may not foot due to rounding.

For the year ended December 31, 2015, the Company recognized a benefit of $0.2 million in General and administrative expenses within the Consolidated Statement of Income due to the change in fair value measurements using a level three valuation technique. For the years ended December 31, 2014 and 2013, the Company recognized an expense and benefit, respectively, of $0.5 million and $0.9 million in General and administrative expenses due to the change in fair value measurements using a level three valuation technique. These adjustments were the result of using revised forecasts to operating results, updates to the probability of achieving the revised forecasts and updated fair value measurements that revised the Company's contingent consideration obligations related to the purchase of these businesses.

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 an 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 Company has not recorded impairment charges related to its business acquisitions. 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.

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 Sheet at December 31, 2015 and 2014:



	2015				2014
(millions)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Cash and cash equivalents	$	18.7	$	18.7	$	18.2	$	18.2
Long-term borrowings
Senior credit facility, net of original discount on borrowings and deferred financing costs	223.1		223.1		248.4		248.4
Other obligations	$	2.0	$	2.0	$	2.4	$	2.4

The carrying value of cash and cash equivalents approximates their fair value due to the short-term nature of these financial instruments and would be classified as a Level 1. The fair value of the Senior Credit Facility and Other obligations were estimated to not be materially different from the carrying amount and are generally measured using a discounted cash flow analysis based on current market interest rates for similar types of financial instruments and would be classified as a Level 2.
