5. FAIR VALUE MEASUREMENTS

The fair value measurement standard defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date (referred to as an “exit price”).  Authoritative guidance on fair value measurements and disclosures clarifies that a fair value measurement for a liability should reflect the entity’s non-performance risk.  In addition, a fair value hierarchy is established that prioritizes the inputs to valuation techniques used to measure fair value.  The hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets and liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Fair Value on Recurring Basis

The carrying values of cash and cash equivalents, receivables, net, and accounts payable are considered to be representative of their respective fair values due to the short-term nature of these instruments.  We measure our contingent consideration liabilities related to business combinations at fair value.  For more information see Note 12 – Business Combinations.

Fair Value on Non-Recurring Basis

Fair value measurements were applied to our long-term debt portfolio.  We believe the carrying value of our term loan approximates the fair market value primarily due to the fact that the non-performance risk of servicing our debt obligations, as reflected in our business and credit risk profile, has not materially changed since we assumed our debt obligations under the Amended Credit Agreement.  In addition, due to the floating-rate nature of our term loan, the market value is not subject to variability solely due to changes in the general level of interest rates as is the case with a fixed-rate debt obligation.  Based on active market trades of our Senior Notes close to June 30, 2018 (level 1 fair value measurement), we estimate that the fair value of the Senior Notes is approximately $385.0 million compared to a carrying value of $400.0 million at June 30, 2018.

During all periods presented, there were no transfers between fair value hierarchical levels.
