Fair Value Disclosures [Abstract] |
FAIR VALUE MEASUREMENTS | FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We are required to consider and reflect the assumptions of market participants in fair value calculations. These factors include nonperformance risk (the risk that an obligation will not be fulfilled) and credit risk, both of the reporting entity (for liabilities) and of the counterparty (for assets). We use, as appropriate, a market approach (generally, data from market transactions), an income approach (generally, present value techniques), and/or a cost approach (generally, replacement cost) to measure the fair value of an asset or liability. These valuation approaches incorporate inputs, such as observable, independent market data, that management believes are predicated on the assumptions market participants would use to price an asset or liability. These inputs may incorporate, as applicable, certain risks such as nonperformance risk and credit risk. The FASB has established a three-level fair value hierarchy that prioritizes the inputs used to measure fair value. The fair value hierarchy gives the highest priority to quoted market prices (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of inputs used to measure fair value are as follows:
▪ | Level 1—quoted prices in active markets for identical assets or liabilities accessible by the reporting entity.
▪ | Level 2—observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
▪ | Level 3—unobservable for an asset or liability. Unobservable inputs should only be used to the extent observable inputs are not available.
The fair value hierarchy gives the highest priority to quoted market prices (Level 1) and the lowest priority to unobservable inputs (Level 3). Financial assets and liabilities have been classified in their entirety based on the lowest level of input that is significant to the fair value measurement. When available, we use quoted market prices to determine fair value and we classify such measurements within Level 1. In some cases where market prices are not available, we make use of observable market-based inputs (i.e., Bloomberg and commodity exchanges) to calculate fair value, in which case the measurements are classified within Level 2. When quoted market prices or observable market-based inputs are unavailable, or when our fair value measurements incorporate significant unobservable inputs, we would classify such measurements within Level 3. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following tables set forth, by level within the fair value hierarchy, our non-pension financial assets and liabilities that were measured at fair value on a recurring basis as of July 31, 2011 and May 1, 2011:

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain assets and liabilities are measured at fair value on a nonrecurring basis after initial recognition; 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. During the first quarter of fiscal 2012, we had no assets or liabilities that were measured and recorded at fair value on a nonrecurring basis. Other Financial Instruments We determine the fair value of public debt using quoted market prices. We value all other debt using discounted cash flow techniques at estimated market prices for similar issues. The following table presents the fair value and carrying value of long-term debt, including the current portion of long-term debt as of July 31, 2011 and May 1, 2011.

The carrying amounts of cash and cash equivalents, accounts receivable, notes payable and accounts payable approximate their fair values because of the relatively short-term maturity of these instruments.
