The change in the cost value of total intangible assets from December 31, 2012 to June 30, 2013 is a result of the effect of foreign currency translations.

c. Long-Term Assets

In the first quarter of this year, we had a sale to a customer of our Communications Systems segment of which $2,031, net of interest, had a payment term of greater than one year. This sale was in order to facilitate this customer’s ability to support a soldier modernization initiative. We expect this receivable to be fully collected within two years. Currently $1,174 is classified as long-term.
