Fair Value Disclosures [Abstract]

FAIR VALUE

FAIR VALUE

Fair value is the price that would be received from selling an asset for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants as of the measurement date. Applicable accounting guidance provides a hierarchy for inputs used in measuring fair value that prioritize the use of observable inputs over the use of unobservable inputs, when such observable inputs are available. The three levels of inputs that may be used to measure fair value are as follows:

• Level 1 - Quoted prices in active markets for identical assets or liabilities.

• Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-driven valuations in which all significant inputs are observable or can be derived principally from, or corroborated with, observable market data.

• Level 3 - Fair value is derived from valuation techniques in which one or more significant inputs are unobservable, including assumptions and judgments made by the Company.

Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the observable inputs may result in a reclassification of assets and liabilities within the three levels of the hierarchy outlined above.

Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis

The Company measures certain assets and liabilities at fair value on a recurring basis such as our financial instruments, marketable securities and contingent consideration related to business combinations.

There have been no transfers between Level 1, 2 or 3 assets or liabilities during the three and six months endedMarch 30, 2012. The Company recognizes transfers within the fair value hierarchy at the end of the fiscal quarter in which the change in circumstances that caused the transfer occurred.

Due to the illiquid markets for the Company's ARS, discussed in Note 3, Marketable Securities, these securities are appropriately classified as a Level 3 asset.

The Company has classified its contingent consideration recorded for business combinations in fiscal 2011 as a Level 3 liability. The contingent consideration liability is computed based on expected revenue to be generated by the acquired enterprises using a weighted probability income approach. Revenue assumptions used in the calculation require significant management judgment. Accordingly, the liability is classified as Level 3. The Company reassesses the fair value of the contingent consideration on a quarterly basis and determined that there was no change during the three and six months endedMarch 30, 2012.

As of March 30, 2012, assets and liabilities recorded at fair value on a recurring basis consist of the following (in thousands):                         

			Fair Value Measurements

The following table summarizes the changes to Level 3 assets and liabilities recorded at fair value on a recurring basis as of March 30, 2012 (in thousands):

	Auction Rate Securities		Contingent Consideration

Purchases	805		—
Balance at March 30, 2012	$	3,093	$	59,400

Transfers into Level 3 assets consist of ARS acquired from AATI during the three and six months ended March 30, 2012.

Assets Measured and Recorded at Fair Value on a Nonrecurring Basis

The Company's non-financial assets and liabilities, such as goodwill, intangible assets, and other long lived assets resulting from business combinations are measured at fair value using income approach valuation methodologies at the date of acquisition and subsequently re-measured if there are indicators of impairment. There were no indicators of impairment identified during the three and six months endedMarch 30, 2012.
