Note 13. 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 2016 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 September 30, 2017, 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. As of September 30, 2017, we had no fixed-rate debt outstanding.

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.

The following table summarizes assets and liabilities measured at fair value on a recurring basis for the interest rate swap derivative financial instrument:

Our policy is to manage interest expense using a mix of fixed and variable rate debt. To manage this mix effectively, we may enter into interest rate swaps to exchange the difference between fixed and variable interest amounts.

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. Counterparties to these derivative contracts are highly rated financial institutions which management believes carry only a minimal risk of nonperformance.

We have elected to present the derivative contracts on a gross basis in the Condensed Consolidated Balance Sheets included within other current assets, other non-current assets, other current liabilities and other non-current liabilities. If the derivative contract were presented on a net basis, the derivative would reflect in a net liability position of $1.5 million as of September 30, 2017. We do not have any cash collateral due under such agreements.

As of September 30, 2017, we had no gains or losses in accumulated other comprehensive income related to the interest rate swap. Additionally, during the nine months ended September 30, 2016, when the interest rate swap was accounted for in accordance with hedge accounting, the periodic settlements and related reclassification of other comprehensive income was $1.4 million of net hedging losses on the interest rate swap in the interest expense line on the Condensed Consolidated Statements of Operations and Comprehensive Income. The “Derivative loss (gain) on change in interest rate swap fair value” line on the Condensed Consolidated Statements of Operations and Comprehensive Income includes interest rate swap settlements of $0.3 million and $1.3 million for the three-month and nine-month periods ended September 30, 2017, and $0.6 million for the three-month and nine-month periods ended September 30, 2016. Effective October 27, 2017, we terminated our interest rate swap with a cash payment of $1.3 million. Therefore, we classified all amounts related to the interest rate swap as current assets and current liabilities on our balance sheet as of September 30, 2017.
