FAIR VALUE MEASUREMENTS [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The Company's cash and cash equivalents, restricted cash, restricted investments and diesel fuel swaps represent the financial assets and liabilities that were accounted for at fair value on a recurring basis as of May 2, 2015. As required, financial assets and liabilities are classified in the fair value hierarchy in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels. The fair value of the Company's cash and cash equivalents was $870.4 million and $387.1 million, at May 2, 2015 and May 3, 2014, respectively. The fair value of the Company's restricted cash was $7.2 billion and $0.0 at May 2, 2015 and May 3, 2014, respectively. The fair value of the Company's restricted investments was $90.9 million and $87.9 million, at May 2, 2015 and May 3, 2014, respectively. These fair values were determined using Level 1 measurements in the fair value hierarchy. The fair value of the diesel fuel swaps was a liability of $3.2 million as of May 2, 2015 and an asset of less than $0.1 million as of May 3, 2014 and were estimated using Level 2 measurements in the fair value hierarchy, which used discounted cash flow calculations based upon diesel fuel cost curves. The estimated fair value of the Company’s long-term debt was $7.9 billion as of May 2, 2015 and $770.8 million as of May 3, 2014. The fair value of the Senior Notes is determined through the use of a discounted cash flow analysis using Level 3 inputs as there are no quoted prices in active markets for these notes. The discount rate used in the analysis was based on borrowing rates available to the Company for debt of the same remaining maturities, issued in the same private placement debt market. The carrying values of the Company's acquisition notes and Term Loan B approximate their fair values because they were recently issued. The carrying value of the Company's Unsecured Credit Agreement at May 3, 2014 approximated its fair value because the interest rates vary with market interest rates. Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The Company did not record any significant impairment charges during the 13 weeks ended May 2, 2015.
