* On November 15, 2011, we acquired certain patents. The total purchase price was $0.6 million. Payment terms under the agreement require us to pay $0.2 million upon signing the purchase agreement, $0.2 million 18 months following the purchase date and a final payment of $0.2 million two years following the purchase date. The purchase of these patents is considered to be the acquisition of "defensive intangible assets" and has been accounted for under ASC Topic 350-30-25 "General Intangibles Other than Goodwill", as well as in accordance with ASC Topic 805-50-05 "Acquisition of Assets Rather than a Business". The patents have an amortization period of approximately 11 years.
