[1] Net tangible assets included deferred revenue which was adjusted down from $13 million to $3 million representing our estimate of the fair value of the contractual obligation assumed for support services.

[2] Intangible assets included developed technology, customer relationships and tradename of $60 million, $96 million and $12 million, respectively, which are amortized over their estimated useful lives of seven to eight years.

[3] Goodwill is not tax deductible. The amount resulted primarily from our expectation of synergies from the integration of Clearwell product offerings with our product offerings.
