Assets and Liabilities Measured at Fair Value
For assets and liabilities required to be reported or disclosed at fair value, U.S. 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, other than quoted market prices included within Level 1, are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability.
The Company's assets and liabilities measured or disclosed at fair value were as follows:

The majority of the Company's Level 2 financial liabilities are debt instruments with quoted market prices that are not considered to be traded on "active markets," as defined in U.S. GAAP. Accordingly, the financial instruments are reported in the foregoing tables as Level 2 fair value instruments.
