FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS

Fair Value of Financial Instruments

We use an independent pricing source to determine the fair value of our securities. The independent pricing source utilizes various pricing models for each asset class; including the market approach. The inputs and assumptions for the pricing models are market observable inputs including trades of comparable securities, dealer quotes, credit spreads, yield curves and other market-related data.

We have not adjusted the prices obtained from the independent pricing service and we believe the prices received from the independent pricing service are representative of the prices that would be received to sell the assets at the measurement date (exit price).

The carrying value of the Company's cash equivalents and restricted cash equivalents approximate their fair values due to their short-term maturities.

We did not have any Level 3 financial instruments recognized in our balance sheet as of December 31, 2019 and 2018. There were no transfers between levels as of December 31, 2019 and 2018.

Fair Value of Financial Instruments Disclosure

Long-Term Debt

Our long-term debt is a floating rate debt and the fair value of our floating rate debt approximates its carrying value (exclusive of issuance costs) at December 31, 2019 and 2018. The fair value of our floating rate debt is estimated based on a discounted cash flow, which incorporates credit spreads and market interest rates to estimate the fair value and is considered Level 3 in the hierarchy for fair value measurement.

Derivative Instruments

In June 2019, we entered into an interest rate collar derivative transaction with no upfront premium to mitigate the risk of changes in interest rates on the interest payments on a portion of our floating rate debt. If short-term interest rates increase, we will incur higher interest expense on any future outstanding balances of floating rate debt. We use this derivative as part of our interest rate risk management strategy and designated it as a cash flow hedge. If interest rates rise above the cap strike rate on the contract, we will receive variable-rate amounts and if interest rates fall below the floor strike rate on the contract, we will pay variable-rate amounts.

The following table summarizes the fair value of our derivative instrument at December 31, 2019:



	December 31, 2019
					Fair Market Value
(in millions)	Hedge type	Final settlement date	Notional amount		Other current assets		Accounts payable and other current liabilities
Derivatives designated as hedging instruments
Collar - LIBOR	Cash flow	May 2022	$	213	$	—	$	—

The pre-tax effect of derivative instrument for year ended December 31, 2019 is insignificant and we estimate that an insignificant amount of net derivative gains or losses included in other comprehensive income will be reclassified into earnings within the following 12 months. There were no cash flows associated with the derivative for year ended December 31, 2019.

As of December 31, 2019, we do not hold, nor have we posted, any collateral related to the above derivative instrument.

The interest rate collar derivative is classified as Level 2 in the fair value hierarchy as its value is determined using observable inputs such as forward LIBOR curves.
