Assets Held for Sale	3 Months Ended
	Mar. 31, 2018
Discontinued Operations and Disposal Groups [Abstract]
Assets Held for Sale	Assets Held for Sale As of March 31, 2018, we had designated two unused properties as held for sale, due to strategic initiatives, which was unchanged from December 30, 2017. At the time that these properties were designated as “held for sale,” we ceased recognizing depreciation expense on these assets. As of both March 31, 2018, and December 30, 2017, the net book value of total assets held for sale was $0.8 million and was included in “other current assets” in our Consolidated Balance Sheets. We are actively marketing the properties that are designated as held for sale.
