Fair Value Disclosures [Abstract]

Fair Value Measurements

(2) FAIR VALUE MEASUREMENTS

There are various valuation techniques used to estimate fair value, the primary one being the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, we consider the principal or most advantageous market in which we would transact and consider assumptions that market participants would use when pricing the asset or liability. We measure certain financial and nonfinancial assets and liabilities at fair value on a recurring and nonrecurring basis.

Fair Value Hierarchy

The three levels of inputs that may be used to measure fair value are as follows:

• Level 1. Quoted prices in active markets for identical assets or liabilities.

• Level 2. Observable inputs other than quoted prices included within Level 1, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable market data for substantially the full term of the assets or liabilities.

• Level 3. Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities.
