We invest in various financial instruments including corporate and government bonds and notes, commercial paper and auction rate securities. The Company carries these instruments at their fair value in accordance with ASC 820. The framework under the provisions of ASC 820 establishes three levels of inputs that may be used to measure fair value. Each level of input has different levels of subjectivity and difficulty involved in determining fair value.

Level 1instruments generally represent quoted prices for identical assets or liabilities in active markets. Therefore, determining fair value for Level 1 instruments generally does not require significant management judgment, and the estimation is not difficult. Our Level 1 instruments consist of federal agency, municipal or corporate notes and bonds, and commercial paper that are traded in active markets and are classified as Short-term marketable securities on our Consolidated Balance Sheet.

Level 2instruments include inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices for identical instruments in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 instruments include unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Our auction rate securities are classified as Level 3 instruments. Management uses a combination of the market and income approach to derive the fair value of auction rate securities, which include third party valuation results, investment broker provided market information and available information on the credit quality of the underlying collateral. As a result, the determination of fair value for Level 3 instruments requires significant management judgment and subjectivity. Our Level 3 instruments are classified as Long-term marketable securities on our Consolidated Balance Sheet.

During the fiscal year ended December 31, 2011, the following changes occurred in our Level 3 assets (in thousands):

	Year Ended
	December 31, 2011			January 1, 2011
Beginning fair value of Long-term marketable securities	$	10,232		$	12,939
Fair value of securities sold or redeemed	(2,843		)	(4,147		)
Temporary or other-than-temporary fluctuations in fair value	(443		)	1,440
Ending fair value of Long-term marketable securities	$	6,946		$	10,232

In accordance with ASC 320, “Investments - Debt and Equity Securities,” the Company recorded an unrealized loss of $0.1 million during the year ended December 31, 2011 on certain Short-term marketable securities (Level 1 instruments) which has been recorded in Accumulated other comprehensive income. Future fluctuations in fair value related to these instruments that the Company deems to be temporary, including any recoveries of previous write-downs, would be recorded to Accumulated other comprehensive income. For the year ended December 31, 2011, approximately $0.4 million in unrealized losses were recorded in Accumulated other comprehensive income. If the Company were to determine in the future that any further decline in fair value is other-than-temporary, we would record an impairment charge, which could have a materially detrimental impact on our operating results. If we were to liquidate our position in these securities, it is likely that the amount of any future realized gain or loss would be different from the unrealized gain or loss reported in Accumulated other comprehensive income.
