401(k) Plan [Abstract]
401(k) Plan	13. 401(k) Plan We have a 401(k) tax deferred savings plan that covers all eligible employees based in the U.S. As part of our financial improvement plan announced in the third quarter of fiscal 2016, we ceased making discretionary contributions at that time. In December 2016, we reinstated discretionary contributions which we expect to continue into our fiscal year 2018. Our contribution during fiscal years 2017, 2016 and 2015 were $171,000, $385,000 and $640,000, respectively.
