There were no impairment charges recorded during the nine months ended April 30, 2015. The decrease in the gross carrying amount of other intangible assets as of April 30, 2015 compared to July 31, 2014 was due the effect of currency fluctuations during the nine month period. The gross carrying amount of goodwill and other intangible assets in the condensed consolidated balance sheet at April 30, 2015 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 April 30, 2015. Amortization expense on intangible assets was $2,900 and $4,713 for the three months ended April 30, 2015 and 2014, respectively, and $9,251 and $14,837 for the nine months ended April 30, 2015 and 2014, respectively. The amortization over each of the next five fiscal years is projected to be $11,768, $9,670, $7,388, $6,634 and $6,352 for the fiscal years ending July 31, 2015, 2016, 2017, 2018 and 2019, respectively.
