The value of goodwill and other intangible assets in the condensed consolidated financial statements at October 31, 2011 differs from the value assigned to them in the original allocation of purchase price due to the effect of fluctuations in the exchange rates used to translate the financial statements into the United States Dollar between the date of acquisition and October 31, 2011.
Amortization expense on intangible assets was $4,080 and $5,147 for the three-month periods ended October 31, 2011 and 2010, respectively. The amortization over each of the next five fiscal years is projected to be $16,436, $10,578, $5,617, $5,263 and $4,163 for the fiscal years ending July 31, 2012, 2013, 2014, 2015 and 2016, respectively.
