FAIR VALUE OF ASSETS AND LIABILITIES

Note 5    FAIR VALUE OF ASSETS AND LIABILITIES

        Fair value is defined as "the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price)." The standard establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value measurements. This accounting standard, among other things, requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value.

        The table below presents the balances of investments measured at fair value on a recurring basis at December 31, 2011:

        The Company's investments, with the exception of auction-rate securities, are classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities and money market securities. Such instruments are generally classified within Level 1 of the fair value hierarchy. The types of instruments valued based on other observable inputs include corporate debt securities and other obligations. Such instruments are generally classified within Level 2 of the fair value hierarchy.

        Auction-rate securities are classified within Level 3 as significant assumptions are not observable in the market. The total amount of assets measured using Level 3 valuation methodologies represented less than 1% of total assets as of December 31, 2011.

        A summary of the changes in Level 3 assets measured at fair value on a recurring basis is as follows:
