[1] Net tangible assets included deferred revenue, which was adjusted down from $286 million to $68 million, representing our estimate of the fair value of the contractual obligation assumed for the support of the authentication business.

[2] Intangible assets included customer relationships of $226 million, developed technology of $123 million and trade names of $5 million, which are amortized over their estimated useful lives of 18 months to nine years. The weighted-average estimated useful lives were 8.0 years for customer relationships and 9.0 years for developed technology. Intangible assets also included indefinite-lived trade names and trademarks of $274 million.

[3] Goodwill is partially tax deductible. The goodwill amount resulted primarily from our expectation of synergies from the integration of VeriSign product offerings with our existing product offerings.

[4] The fair value of the noncontrolling interest was calculated on a market basis using the closing stock price of VeriSign Japan on the date of acquisition.
