[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 customer relationships, developed technology, and trade names of $82 million, $60 million, and $12 million, respectively, which are amortized over their estimated useful lives of seven to nine 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 existing product offerings.
