During the third quarter the Company acquired Glutino which increased goodwill by $19,506, trademarks by $13,604 and added customer relationships of $25,963. These amounts are subject to revision based on finalization of a valuation. See Note 2 for more information on the Glutino acquisition.

Adjustments to trademarks primarily relate to a legal settlement received of $367 and serve to reduce related costs previously capitalized. Adjustments to patent technology primarily relate to the capitalization of legal defense costs associated with the Company’s licensed patents from Brandeis University.  Amortization expense was $1,667 and $4,010 for the three and nine months ended September 30, 2011, respectively, and $1,019 and $3,052 for the three and nine months ended September 30, 2010, respectively.  At June 30, 2010, the Company recognized an impairment loss on goodwill of $130,000 (see Note 7 for further details).

Based on the Company's amortizable intangible assets as of September 30, 2011, amortization expense is expected to be approximately $1,900 for the remainder of 2011 and range from approximately $7,000 to $7,600 for each of the next five fiscal years.
