This excerpt taken from the ATVI 8-K filed Nov 5, 2008.
As of September 30, 2007 and December 31, 2006, Vivendi Games had $1.35 million and $2.35 million, respectively, held in escrow accounts associated with certain businesses acquired during 2006. During the nine months ended September 30, 2007, partial payment was released from escrow to the selling shareholders of the acquired businesses. Additional funds will be released from the escrow account after September 30, 2007, to either Vivendi Games or the sellers of the acquired businesses, depending on the sufficiency of the net working capital delivered at the time of acquisition, as defined, or the existence of acquired businesses liabilities that were not previously recorded within the working capital delivered. To the extent amounts are released from escrow to the sellers, additional goodwill will be recorded at the time of release.
