FAIR VALUE MEASUREMENT

NOTE 6—FAIR VALUE MEASUREMENT

The carrying amounts of cash, accounts receivable and accrued interest approximate estimated fair value. The U.S. Treasury securities, classified as cash equivalents, are measured using quoted market prices available on active markets. In measuring the fair value of the Senior Secured Notes, the Company used market information. These estimates require considerable judgment in interpreting market data, and changes in assumptions or estimation methods could significantly affect the fair value estimates.

The following table presents estimated fair value, and related carrying amounts, as of June 30, 2012 and December 31, 2011:
