Note 12. Fair Value Measurements

We present fair value measurements and disclosures applicable to both our financial and nonfinancial assets and liabilities that are measured and reported on a fair value basis. Fair value is an exit price representing the expected amount we would receive to sell an asset or pay to transfer a liability in an orderly transaction with market participants at the measurement date. We have followed consistent methods and assumptions to estimate the 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. At June 30, 2017, the carrying values of all 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 June 30, 2017, we had no significant 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 the assets and liabilities measured at fair value on a recurring basis for our 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 in which we agree to exchange the difference between fixed and variable interest amounts calculated by reference to an agreed upon notional principal amount.

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 we believe carry only a minimal risk of nonperformance.

We have elected to present the derivative contracts on a gross basis in the Condensed Consolidated Balance Sheet included within other current assets, other non-current assets, other current liabilities and other non-current liabilities. To the extent we presented the derivative contract on a net basis, we would have a derivative in a net liability position of $1.7 million as of June 30, 2017. We do not have any cash collateral due under such agreements.

As of June 30, 2017, we reported no gains or losses in accumulated other comprehensive income related to the interest rate swaps. Additionally, during the three and six months ended June 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 $0.5 million and $0.9 million, respectively, of net hedging losses on the interest rate swap in the interest expense line on the Condensed Consolidated Statements of Operations. We recognized $0.5 and $1.0 million of interest rate swap settlements during the three and six months ended June 30, 2017, in the “Derivative losses on change in interest rate swap fair value” line on the Condensed Consolidated Statements of Operations. If there are no changes in the interest rates for the next twelve months, we expect to make $1.3 million in cash payments related to the interest rate swap.
