Fair Value of Financial Instruments

6 Months Ended

Jun. 30, 2016

Fair value is the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable.

The market approach is applied for recurring fair value measurements and endeavors to utilize the best available information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair value balances are classified based on the observability of those inputs.

A fair value hierarchy prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). Level 2 measurements utilize observable inputs in markets other than active markets.

In estimating the fair value of the financial instruments presented, we used the following methods and assumptions:

Cash and cash equivalents

For cash and cash equivalents, we believe that the carrying value is a reasonable estimate of fair value due to the short-term nature of the instruments.

Restricted cash

Restricted cash is comprised of certificates of deposit that are pledged for various letters of credit. We deem the carrying value to be a reasonable estimate of fair value due to the nature of these instruments.

Marketable securities

Marketable securities are classified as available-for-sale securities and are valued using quoted prices in active markets.

Contingent consideration

The fair value of the contingent consideration was estimated using the Monte Carlo simulation model, which relies on significant assumption and estimates including discount rates and future market conditions, among others.

Long-term debt

The fair value of long-term debt was estimated based on the current rates available to us for similar debt of the same remaining maturities and consideration of our default and credit risk.

Interest rate swap agreements

The fair value of the interest rate swap agreements was estimated based on market-value quotes received from the counterparties to the agreements.

The fair values of our financial instruments as of June 30, 2016 are presented in the following table:

There were no transfers between Level 1, Level 2 or Level 3 securities during the three and six months ended June 30, 2016. In connection with the contingent consideration, we recorded $0.9 million of unrealized losses in our condensed consolidated statement of operations for the three and six months ended June 30, 2016.
