As of March 31, 2012, the Company held 15 corporate debt securities with an aggregate fair value of $31,328 that were in an unrealized loss position for less than 12 months. The gross unrealized losses of $19 at March 31, 2012 represent temporary impairments on corporate debt securities related to multiple issuers, and were primarily caused by fluctuations in U.S. interest rates. The Company has determined that the gross unrealized losses on these securities at March 31, 2012 are temporary in nature. The Company evaluates securities for other-than-temporary impairment on a quarterly basis. Impairment is evaluated considering numerous factors, and their relative significance varies depending on the situation. Factors considered include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the issuer, and our intent and ability to hold the security in order to allow for an anticipated recovery in fair value.

All of the Company's long-term available-for-sale securities were due between one and two years as of March 31, 2012.

The fair values of the Company's financial instruments are the amounts that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants and are recorded using a hierarchal disclosure framework based upon the level of subjectivity of the inputs used in measuring assets and liabilities. The levels are described below:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

Level 3: Unobservable inputs are used when little or no market data is available.

The Company classifies its financial instruments within Level 1 or Level 2 of the fair value hierarchy. This is because the Company values financial instruments using quoted market prices or alternate pricing sources and models utilizing market observable inputs. The Company held no Level 3 financial instruments as of March 31, 2012 and December 31, 2011.
