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 the 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.

The Company periodically transfers U.S. Treasury securities and obligations of U.S. government corporations and agencies between Level I and Level II fair value measurements dependent upon the level of trading activity for the specific securities at the measurement date.  The Company’s policy regarding the timing of transfers between Level I and Level II is to measure and record the transfers at the end of the reporting period.  At December 31, 2014, there were $14 million of transfers from Level I to Level II and $1 million of transfers from Level II to Level I.  The Company utilizes matrix pricing services to estimate fair value for securities which are not actively traded on the measurement date.  The Company designates these securities as Level II fair value measurements.  The aggregate carrying amount of the Company’s life insurance contracts and other non-majority owned investments, which approximates fair value, was $84 million and $37 million as of December 31, 2014 and December 31, 2013, respectively.
