ASSETS AND LIABILITIES MEASURED AT FAIR VALUE

ASSETS MEASURED AT FAIR VALUE

The following tables present information about our financial assets measured at fair value, on a recurring basis, as of September 30, 2012, and December 31, 2011. The tables indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value. We did not have any financial liabilities measured at fair value, on a recurring basis, as of September 30, 2012, and December 31, 2011.

In the third quarter of 2012, we reclassified our investments in corporate bonds and municipal bonds from Level 1 into Level 2 as we believe this more appropriately reflects the level of inputs available for valuing these financial instruments. There were no transfers in or out of Level 1, 2, or 3 fair value measurements during the three months or nine months ended September 30, 2012.
