FAIR VALUE OF FINANCIAL INSTRUMENTS
 
Financial instruments recorded at fair value on the Consolidated Balance Sheet are classified using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. The fair value hierarchy has the following levels:
 
Level 1   – 
valuation based on quoted prices (unadjusted) in active markets for identical assets or liabilities;
Level 2   – 
valuation techniques based on inputs other than quoted prices included in level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and
Level 3   – 
valuation techniques using inputs for the asset or liability that are not based on observable market data (unobservable inputs).
 
The fair value hierarchy requires the use of observable market inputs whenever such inputs exist. A financial instrument is classified to the lowest level of the hierarchy for which a significant input has been considered in measuring fair value. The following table presents the financial instruments recorded at fair value, classified using the fair value hierarchy described above:
