Goodwill, gross intangible assets, and net intangible assets were all subject to foreign currency translation effects. Changes in our goodwill and gross intangible assets from November 30, 2013 to August 31, 2014 were primarily the result of recent acquisitions and foreign currency translation effects, partially offset by the removal of fully amortized intangible assets. The change in net intangible assets was primarily due to current year amortization, partially offset by the acquisitions made in the third quarter of 2014.
