Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments: Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date. The Company uses a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company’s financial instruments consist of cash and cash equivalents, short-term receivables, trade payables, debt instruments and interest rate swaps. Due to their short-term nature, the carrying values of cash and cash equivalents, short-term receivables and trade payables approximate current fair value at each balance sheet date. The Company had $543.0 million in borrowings under its debt facilities (as discussed in Note 5) at June 30, 2018, $427.5 million in borrowings at December 30, 2017, and $455.0 million in borrowings at July 1, 2017. Based on market interest rates (Level 2 inputs), the carrying value of borrowings in our debt facilities approximates fair value for each period reported. The fair value of the Company’s interest rate swaps is determined based on the present value of expected future cash flows using forward rate curves (a Level 2 input). As described in further detail in Note 6, the fair value of the interest rate swaps, excluding accrued interest, was an $8.4 million asset at June 30, 2018, a $5.2 million asset at December 30, 2017 and a $3.0 million asset at July 1, 2017.
