Goodwill

9. Goodwill

Goodwill represents the excess of the cost of an acquired entity over the fair value assigned to the assets purchased and liabilities assumed in connection with the Company’s acquisition. The carrying amount of goodwill is evaluated annually, and between annual evaluations if events occur or circumstances change indicating that the carrying amount of goodwill may be impaired.

The $8.0 million of goodwill at June 30, 2012 and September 30, 2011 is related to the In Vitro Diagnostics reporting unit. The goodwill was not impaired based on the outcome of the fiscal 2011 annual impairment test, and there have been no events or circumstances that have occurred in fiscal 2012 to indicate that the goodwill may be impaired.
