The gross carrying amount of goodwill and other intangible assets in the condensed consolidated balance sheets at October 31, 2014 differs from the value assigned to them in the original allocation of purchase price due to impairments and the effect of currency fluctuations between the date of acquisition and October 31, 2014.
Amortization expense on intangible assets was $3,369 and $5,077 for the three months ended October 31, 2014 and 2013, respectively.
