Subsequent Events [Abstract]
Subsequent Events	Subsequent Events In April 2013, we signed a loan agreement with the Mississippi Development Authority ("MDA") for draws up to $1.5 million at an interest rate of 2.25%. Fixed principal and interest payments commence in March 2014 and continue until February 2021. Draws under the agreement are permitted for purchases of certain equipment for our Tupelo, Mississippi location. In May 2013, we announced to our French employees that we have begun a process of reducing our indirect staff through a social plan. This announcement commences negotiations at each of our French locations. We perform review procedures for subsequent events, and determine any necessary disclosures that arise from such evaluation, up to the date of issuance of our annual and interim reports.
