Fair Value Measurements

We account for certain assets and liabilities at fair value. Fair value is defined as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date, assuming the transaction occurs in the principal or most advantageous market for that asset or liability.

Fair Value Hierarchy

The hierarchy below lists three levels of fair value based on the extent to which inputs used in measuring fair value are observable in the market. We categorize each of our fair value measurements in one of these three levels based on the lowest level input that is significant to the fair value measurement in its entirety. These levels are:

 

Level 1: 

Quoted prices in active markets for identical assets or liabilities;

 

Level 2: 

Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-based valuation techniques in which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

 

Level 3: 

Unobservable inputs that are supported by little or no market activity and typically reflect management's estimates of assumptions that market participants would use in pricing the asset or liability.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

There were no assets and liabilities measured at fair value on a recurring basis at March 31, 2019 or December 31, 2018.

Fair Value of Other Financial Instruments

The estimated fair value of each class of financial instruments at March 31, 2019 was as follows:

Cash and cash equivalents The carrying amount of $18.8 million approximates fair value due to the short maturity of those instruments (less than three months).

Debt The estimated fair value of outstanding borrowings under the Credit Agreement, which includes term loan facilities and a revolving credit facility (see Note 11), is determined based on the fair value hierarchy as discussed above.

The Term Loans are actively traded and therefore are classified as Level 1 valuations. The estimated fair value is based on the last quoted price of the Term Loans through March 31, 2019. The Revolving Credit Facility is not actively traded and therefore is classified as a Level 2 valuation based on the market for similar instruments.  There was no amount outstanding under the Revolving Credit Facility as of March 31, 2019. The estimated fair value and carrying amount of outstanding borrowings under the Term Loans at March 31, 2019 were $1,146 million and $1,165 million, respectively.
