FAIR VALUE MEASUREMENTS
NOTE 21 - FAIR VALUE MEASUREMENTS

The accounting framework for determining fair value includes a hierarchy for ranking the quality and reliability of the information used to measure fair value, which enables the reader of the financial statements to assess the inputs used to develop those measurements. The fair value hierarchy consists of three tiers as follows:

Level 1- These are investments where values are based on unadjusted quoted prices for identical assets in an active market the Company has the ability to access.

Level 2- These are investments where values are based on quoted market prices that are not active or model derived valuations in which all significant inputs are observable in active markets.

Level 3- These are investments where values are derived from techniques in which one or more significant inputs are unobservable.

The following are the major categories of assets measured at fair value on a recurring basis using quoted prices in active markets for identical assets (Level 1), significant other observable inputs (Level 2) and significant unobservable inputs (Level 3):
