Assets and Liabilities Measured at Fair Value
For assets and liabilities required to be reported at fair value, GAAP provides a hierarchy that prioritizes inputs to valuation techniques used to measure fair value into three broad levels. Level 1 inputs are quoted market prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 2 inputs are inputs, other than quoted market prices included within Level 1, that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. Liberty does not have any assets or liabilities required to be measured at fair value considered to be Level 3.
Liberty's assets and liabilities measured at fair value are as follows:

The majority of Liberty's Level 2 financial assets and liabilities are debt instruments with quoted market prices which are not considered to be traded on "active markets," as defined in GAAP and other financial instruments valued based on financial models that use observable market data such as interest rates, stock prices and volatilities. Accordingly, the financial instruments are reported in the foregoing table as Level 2 fair value.
