[1] We initiated a restructuring plan during the third quarter of fiscal year 2013. Under the plan, we eliminated certain positions in the US., Mexico, China, and Europe, and transitioned some of these positions to lower cost locations. The pre-tax charges incurred during fiscal year 2013 included $1.9 million for severance and related benefits and an immaterial amount of accelerated amortization on leasehold assets with no alternative future use.
