Changes in our goodwill and gross intangible assets from November 30, 2012 to November 30, 2013 were primarily the result of our recent acquisition activities. Goodwill associated with the Polk acquisition was primarily recognized in the Americas segment, and none of the goodwill associated with the transaction is expected to be deductible for tax purposes. The change in net intangible assets was primarily due to the addition of intangible assets associated with the acquisitions described in Note 3, Business Combinations, partially offset by current year amortization. Goodwill, gross intangible assets, and net intangible assets were all subject to foreign currency translation effects.
