Fair Value Measurements Fair Value Measurements
Assets and liabilities recorded at fair value in the Consolidated Balance Sheets are categorized based upon observable or unobservable inputs used to estimate fair value. Level inputs are as follows:
Level Input: Input Definition:
Level I Inputs are unadjusted, quoted prices for identical assets or liabilities in active markets at the measurement date.
 
Level II Inputs other than quoted prices included in Level I that are observable for the asset or liability through corroboration with market data at the measurement date.
 
Level III Unobservable inputs that reflect management's best estimate of what market participants would use in pricing the asset or liability at the measurement date.
