The purchase price allocation includes $20,260,000 of acquired  intangible assets, as follows: The following table summarizes our allocation of the purchase price  to the estimated fair values of the assets acquired and liabilities  assumed at the date of acquisition: The deferred tax liability of $3,522,000 results primarily because  the amortization expense related to certain intangible assets is not  deductible for income tax purposes. Approximately $7,680,000 of  the intangible assets is deductible for U.S. income tax purposes  over a period of 15 years from the acquisition date. Goodwill of $35,683,000 represents the premium we paid over the  fair value of the net tangible and intangible assets we acquired.  We paid this premium for a number of reasons, including the stra- tegic benefits of expanding our equity data, especially in North  America and Europe; expanding our international brand presence,  products, and services; and enhancing our offshore data facilities.  The UK-based investor relations website business is a new market  for us that leverages our data and analytics. Approximately $8,900,000 of the goodwill is deductible for U.S.  income tax purposes over a period of 15 years from the acquisition date. In October 2008, we acquired Fundamental Data Limited  (Fundamental Data), a leading provider of data on closed-end funds  in the United Kingdom for $18,497,000 in cash including post-clos- ing adjustments and transaction costs directly related to the acqui- sition, less acquired cash. Fundamental Data’s flagship product is  FundWeb, an online subscription service allowing clients access to  the company’s comprehensive database. Fundamental Data also  provides data feeds, website feeds, and report outsourcing services  including production of fund fact sheets. It also offers an online  database of publicly issued documents relating to closed-end funds.  We began including the financial results of this acquisition in our  Consolidated Financial Statements on October 2, 2008. The purchase price allocation includes $9,276,000 of acquired intan- gible assets, as follows: The recorded goodwill of $12,844,000 for Fundamental Data repre- sents the premium we paid over the fair value of the net tangible  and intangible assets we acquired. We paid this premium for a  number of reasons, including Fundamental Data’s leadership posi- tion in global closed-end fund data. The deferred tax liability of $2,597,000 results mainly because the  amortization expense related to the intangible assets is not deduct- ible for income tax purposes. The goodwill we recorded is also not  considered deductible for income tax purposes.
