|FAIR VALUE OF FINANCIAL INSTRUMENTS
FAIR VALUE OF FINANCIAL INSTRUMENTS:
Authoritative guidance establishes a framework for measuring fair value and requires disclosures about fair value measurements for financial instruments. This guidance emphasizes that fair value is a market-based measurement, not an entity-specific measurement, and states that a fair value measurement should be determined based on assumptions that market participants would use in pricing an asset or liability. It establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The hierarchy includes three levels:
The methods and assumptions we use to estimate the fair value for each class of our financial instruments are presented in Notes 1 and 7 to our consolidated financial statements included in our 2015 Annual Report and have not changed significantly during the three months ended May 31, 2015. The carrying amounts of certain of our financial instruments, including cash and cash equivalents, accounts receivable, accounts payable and notes payable to banks, approximate fair value as of May 31, 2015, and February 28, 2015, due to the relatively short maturity of these instruments. As of May 31, 2015, the carrying amount of long-term debt, including the current portion, was $7,216.7 million, compared with an estimated fair value of $7,559.7 million. As of February 28, 2015, the carrying amount of long-term debt, including the current portion, was $7,295.6 million, compared with an estimated fair value of $7,378.6 million.
The following table presents our financial assets and liabilities measured at estimated fair value on a recurring basis.
Our foreign currency contracts consist of foreign currency forward and option contracts which are valued using market-based inputs, obtained from independent pricing services, into valuation models. These valuation models require various inputs, including contractual terms, market foreign exchange prices, interest-rate yield curves and currency volatilities. Commodity derivative fair values are based on quotes from respective counterparties. Quotes are corroborated by using market data. Interest rate swap fair values are based on quotes from respective counterparties. Quotes are corroborated by using discounted cash flow calculations based upon forward interest-rate yield curves, which are obtained from independent pricing services. AFS debt securities are valued using market-based inputs into discounted cash flow models.
