Fair Value Disclosures [Abstract]

Fair Value

FAIR VALUE

In accordance with ASC 820 - Fair Value Measurements and Disclosure (“ASC 820”), the Company groups its financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:

Level 1 - Valuation is based upon quoted market price for identical instruments traded in active markets.

Level 2 - Valuation is based upon quoted market prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market. Valuation techniques include use of discounted cash flow models and similar techniques.

The Company has cash equivalents classified as Level 1 and has no Level 2 securities. The Company's ARS, discussed in Note 4, Marketable Securities, are classified as Level 3 assets. There have been no transfers between Level 1, Level 2 or Level 3 assets during the fiscal year ended September 30, 2011. There have been no purchases, sales, issuances or settlements of the marketable securities classified as Level 3 assets during the fiscal year ended September 30, 2011.

The Company has classified its contingent consideration recorded for business combinations as a Level 3 liability. There have been no transfers of or changes to the value of this Level 3 liability during the fiscal year ended September 30, 2011.

Non-Financial 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 at the date of acquisition and subsequently re-measured if there is an indicator of impairment. There were no indicators of impairment identified during the fiscal year ended September 30, 2011.
