2. Fair Value Disclosures

Cash Equivalents and Short-term Investments

The financial instruments of the Company measured at fair value on a recurring basis are cash equivalents and short-term investments.

The Company's fixed income available-for-sale securities consist of high quality, investment grade securities. The Company values these securities based on pricing from pricing vendors, who may use quoted prices in active markets for identical assets (Level 1) or inputs other than quoted prices that are observable either directly or indirectly (Level 2) in determining fair value. However, the Company currently classifies all of its fixed income available-for-sale securities as having Level 2.

The types of instruments valued based on quoted market prices in active markets include most money market securities. Such instruments are generally classified within Level 1 of the fair value hierarchy.

The types of instruments valued based on quoted prices in markets that are less active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency are generally classified within Level 2 of the fair value hierarchy and include most U.S. treasury securities and most investment-grade corporate commercial paper.

The types of instruments valued based on unobservable inputs which reflect the reporting entity's own assumptions or data that market participants would use in valuing an instrument are generally classified within Level 3 of the fair value hierarchy.

In January 2010, the FASB ratified ASU 2010-06 "Fair Value Measurements and Disclosures – Improving Disclosures about Fair Value Measurements" ("ASU 2010-06"). ASU 2010-06 requires new disclosures for significant transfers in and out of Level 1 and 2 of the fair value hierarchy and the level of disaggregation of assets or liabilities and the valuation techniques and inputs used to measure fair value. The Company adopted the updated guidance which was effective for the Company's annual reporting period at December 31, 2009, with the exception of new Level 3 activity disclosures, which was adopted January 1, 2011. The adoption of this guidance did not have a material impact on its consolidated results of operations and financial condition.

Financial instruments measured at fair value on a recurring basis as of December 31, 2011 and December 31, 2010 are classified based on the valuation technique in the table below:


	December 31, 2011 Fair value measurements using						Total
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
	(In thousands)
Assets:
U.S. Treasury securities	$	0	$	48,987	$	0	$	48,987
Money market funds		3,617		0		0		3,617

Total assets at fair value	$	3,617	$	48,987	$	0	$	52,604

The above table excludes $3.7 million of cash held in banks.


	December 31, 2010 Fair value measurements using						Total
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)




	(In thousands)
Assets:
U.S. Treasury securities	$	0	$	48,961	$	0	$	48,961
Money market funds		7,356		0		0		7,356

Total assets at fair value	$	7,356	$	48,961	$	0	$	56,317

Subsequent to the issuance of the 2010 consolidated financial statements, the Company determined that $49.0 million of U.S. Treasury securities should have been classified as level 2 investments rather than level 1 in 2010, as the company does not have access to active trading information on such securities. Accordingly, the Company has corrected the classification of the U.S. Treasury securities from level 1 to level 2 in the table above as of December 31, 2010.

The above table excludes $4.9 million of cash held in banks.

Short-term Investments


	December 31, 2011
	Amortized Cost		Gross Unrealized Holding Gains		Gross Unrealized Holding Losses		Fair Value
	(In thousands)
U.S. Treasury securities	$	48,970	$	17	$	0	$	48,987

Total	$	48,970	$	17	$	0	$	48,987


	December 31, 2010
	Amortized Cost		Gross Unrealized Holding Gains		Gross Unrealized Holding Losses		Fair Value
	(In thousands)
U.S. Treasury securities	$	48,942	$	19	$	0	$	48,961

Total	$	48,942	$	19	$	0	$	48,961

The contractual maturities of the Company's available-for-sale securities on December 31, 2011 and December 31, 2010 were all due within one year.

- Definition

Tabular disclosure of the fair value measurement of assets and liabilities which includes [financial] instruments measured at fair value that are classified in stockholders' equity. Such assets and liabilities may be measured on a recurring or nonrecurring basis. The disclosures which may be required or desired include: (1) for assets and liabilities measured on a recurring basis, disclosure may include: (a) the fair value measurements at the reporting date; (b) the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3); (c) for fair value measurements using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to the following: (i) total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings (or changes in net assets), and a description of where those gains or losses included in earnings (or changes in net assets) are reported in the statement of income (or activities); (ii) purchases, sales, issuances, and settlements (net); (iii) transfers in and transfers out of Level 3 (for example, transfers due to changes in the observability of significant inputs); (d) the amount of the total gains or losses for the period in subparagraph (c) (i) above included in earnings (or changes in net assets) that are attributable to the change in unrealized gains or losses relating to those assets and liabilities still held at the reporting date and a description of where those unrealized gains or losses are reported in the statement of income (or activities); (e) the valuation technique(s) used to measure fair value and a discussion of changes in valuation techniques, if any, during the period and (2) for assets and liabilities that are measured at fair value on a nonrecurring basis (for example, impaired assets) disclosure may include, in addition to (a) above: (a) the reasons for the fair value measurements recorded; (b) the same as (b) above; (c) for fair value measurements using significant unobservable inputs (Level 3), a description of the inputs and the information used to develop the inputs; and (d) the valuation technique(s) used to measure fair value and a discussion of changes, if any, in the valuation technique(s) used to measure similar assets and/or liabilities in prior periods. Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.
