Goodwill decreased by $1,832 during the six months ended January 31, 2014. The decrease was due to purchase accounting adjustments of $2,168 for the deferred tax impact related to the release of escrow from the fiscal 2013 acquisition of Precision Dynamics Corporation ("PDC"), partially offset by the positive effects of foreign translation of $336.

Goodwill at January 31, 2014 included $18,225 and $172,280 of accumulated impairment losses within the IDS and WPS segments, respectively, for a total of $190,505.

The Company also has unamortized indefinite-lived trademarks that are classified as other intangible assets. The net book value of these assets was as follows:

The gross carrying amount of goodwill and other intangible assets in the condensed consolidated balance sheets at January 31, 2014, differs from the value assigned to them in the original allocation of purchase price due to the effect of currency fluctuations between the date of acquisition and January 31, 2014.
Amortization expense on intangible assets was $5,047 and $5,015 for the three months ended January 31, 2014 and 2013, respectively, and $10,124 and $9,162 for the six months ended January 31, 2014 and 2013, respectively. The amortization over each of the next five fiscal years is projected to be $19,376, $18,555, $16,364, $13,253 and $11,969 for the fiscal years ending July 31, 2014, 2015, 2016, 2017 and 2018, respectively.
