Subsequent Events [Text Block]	Note 12: Subsequent Events Subsequent to December 31, 2017, the Company decided to vacate its facility in Mt. Airy, North Carolina, and move current operations to a smaller building. While no definitive date for this move has been set yet, the Company anticipates that the move will happen within the next 12 months. The Company incurred a $4.1 million impairment charge in fiscal 2016, when the majority of the plant’s operations were relocated to the Company’s Brazilian production facility. As of December 31, 2017, the carrying value of the building is $2.0 million, and the Company believes that the current fair value exceeds the carrying value. The Company expects that there may be restructuring costs, including severance payments, and equipment relocation costs that will be incurred in connection with this decision. These costs will be recorded as incurred.
