Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS INVESTMENTS The Company invests in marketable securities, principally equity based mutual funds, to mitigate the risk associated with the investment return on employee deferrals of compensation. All of the marketable securities are included in Other assets on the accompanying consolidated balance sheets, and their aggregate fair values were approximately $16.7 million and $12.3 million at the end of fiscal 2017 and fiscal 2016, respectively. These investments are classified as Level 1 within the fair value hierarchy. Investments in marketable securities incurred a net loss of approximately $0.1 million for fiscal 2017 and a net gain of approximately $0.9 million for fiscal 2016. The fair value of the Company's pension plan assets at December 30, 2017 and December 31, 2016, by asset category, are disclosed in Note 10, Employee Benefits Plans, to the consolidated financial statements. FOREIGN EXCHANGE FORWARD CONTRACTS Fair values of any unsettled foreign exchange forward contracts are calculated by using readily observable market inputs (market-quoted currency exchange rates in effect between the U.S. dollar and the currencies of Canada and Mexico) and are classified as Level 2 within the fair value hierarchy. Any unsettled foreign exchange forward contracts are included in other current assets or other current liabilities on the Company's consolidated balance sheet at the end of each fiscal reporting period. At December 30, 2017, the fair value of open foreign currency contracts was not material. At December 31, 2016, there were no open foreign exchange forward contracts. Realized and unrealized gains and losses on foreign currency contracts were not material for fiscal 2017. For foreign currency contracts settled during fiscal 2016 and 2015, the Company realized net losses of $3.2 million and net gains of $3.1 million, respectively. Unrealized gains for fiscal 2015, including mark-to-market adjustments on contracts open at the end of fiscal 2015, were approximately $2.1 million. These amounts are included in other (income) expense, net on the Company's consolidated statement of operations. The were no open foreign currency contracts at the end of fiscal 2016. BORROWINGS As of December 30, 2017, the fair value of the Company's $221.0 million in borrowings under its secured revolving credit facility approximated carrying value. The fair value of the Company's senior notes at December 30, 2017 was approximately $410 million. The fair value of these senior notes with a notional value and carrying value (gross of debt issuance costs) of $400 million was estimated using a quoted price as provided in the secondary market, which considers the Company's credit risk and market related conditions, and is therefore within Level 2 of the fair value hierarchy.
