Commitments and Contingencies Disclosure [Abstract]
Litigation, Commitments and Contingencies	Litigation, Commitments and ContingenciesLitigation. There are no material pending legal proceedings, other than ordinary routine litigation incidental to the business, to which we or any of our subsidiaries are a party or of which any of our property is the subject. Legal fees associated with such matters are expensed as incurred.Environmental Remediation. During fiscal 2018, we recorded a liability of $0.6 million related to estimated remediation expenses associated with existing contamination at our Minneapolis facility. The liability is being reduced as we incur costs related to remediation efforts, and was $0.1 million as of December 29, 2019 and $0.4 million as of March 31, 2019. Given the many uncertainties involved in assessing environmental claims, our reserves may prove to be insufficient. While it is possible that additional expenses related to remediation will be incurred in future periods if currently unknown issues arise, we are unable to estimate the extent of any further financial impact at this time.
