goodwill will be increased by the amount of the additional consideration , if any , when it becomes due and payable for the second annual earn-out .
in addition to the earn-out discussed above , the company increased goodwill related to the suros acquisition in the amount of $ 210 during the year ended september 29 , 2007 .
the increase was primarily related to recording a liability of approximately $ 550 in accordance with eitf 95-3 related to the termination of certain employees who have ceased all services for the company .
approximately $ 400 of this liability was paid during the year ended september 29 , 2007 and the balance is expected to be paid by the end of the second quarter of fiscal 2008 .
this increase was partially offset by a decrease to goodwill as a result of a change in the valuation of certain assets and liabilities acquired based on information received during the year ended september 29 , 2007 .
there have been no other material changes to purchase price allocations as disclosed in the company 2019s form 10-k for the year ended september 30 , 2006 .
