FAIR VALUE MEASUREMENTS

NOTE 5 — FAIR VALUE MEASUREMENTS

Financial instruments recorded on the balance sheet include cash and cash equivalents, trade accounts receivable, marketable securities, notes and accounts payable, and debt.

An allowance for anticipated uncollectible trade receivable amounts is established using a combination of specifically identified accounts to be reserved, and a reserve covering trends in collectibility. These estimates are based on an analysis of trends in collectibility, past experience, and individual account balances identified as doubtful based on specific facts and conditions. Receivable losses are charged against the allowance when we confirm uncollectibility.

All derivative instruments are recognized on our Consolidated Balance Sheet and measured at fair value. Changes in the fair values of derivative instruments that do not qualify as hedges and/or any ineffective portion of hedges are recognized as a gain or (loss) in our Consolidated Statement of Income in the current period. Changes in the fair value of derivative instruments used effectively as cash flow hedges are recognized in other comprehensive income (loss), along with the change in the value of the hedged item. We do not hold or issue derivative instruments for speculative purposes.

The valuation techniques utilized for establishing the fair values of assets and liabilities are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect management’s market assumptions. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value, as follows:

Level 1 Inputs — Quoted prices for identical instruments in active markets.

Level 2 Inputs — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3 Inputs — Instruments with primarily unobservable value drivers.

The following table presents our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy.

Our marketable securities are composed of mainly available-for-sale securities, and are valued using a market approach based on quoted market prices for identical instruments. The availability of inputs observable in the market varies from instrument to instrument and depends on a variety of factors including the type of instrument, whether the instrument is actively traded, and other characteristics particular to the transaction. For most of our financial instruments, pricing inputs are readily observable in the market, the valuation methodology used is widely accepted by market participants, and the valuation does not require significant management discretion. For other financial instruments, pricing inputs are less observable in the market and may require management judgment.

Our cross-currency swap is a liability that has a fair value of $23.1 million at August 31, 2011, that was originally designed to fix our interest and principal payments in euros for the life of our unsecured 6.70% senior notes due November 1, 2015, which resulted in an effective euro fixed-rate borrowing of 5.31%. The basis for determining the rates for this swap included three legs at the inception of the agreement: the U.S. dollar (USD) fixed rate to a USD floating rate; the euro floating to euro fixed rate; and the dollar to euro basis fixed rate at inception. Therefore, we essentially exchanged fixed payments denominated in USD for fixed payments denominated in euros, paying fixed euros at 5.31% and receiving fixed USD at 6.70%. The ultimate payments are based on the notional principal amounts of 150 million USD and approximately 125 million euros. There will be an exchange of the notional amounts at maturity. The rates included in this swap are based upon observable market data, but are not quoted market prices, and therefore, the cross-currency swap is considered a Level 2 liability on the fair value hierarchy. Additionally, this cross-currency swap has been designated as a hedging instrument, and is classified as other long-term liabilities in our Consolidated Balance Sheets.

We have a foreign currency forward contract has a fair value of $6.3 million at August 31, 2011, and is classified in prepaid expenses and other current assets on our Consolidated Balance Sheets. This foreign currency forward contract, which has not been designated as a hedge, was designed to reduce our exposure to the changes in the cash flows of intercompany foreign-currency-denominated loans related to changes in foreign currency exchange rates by fixing the functional currency cash flows. Upon inception of the contract, we purchased 80.4 million USD and sold approximately 59.9 million euros. Changes in the USD/euro exchange rate will either increase or decrease our USD functional currency earnings, and will be reflected in selling, general and administrative expenses on our Consolidated Statements of Income. The foreign currency forward contract matures on November 23, 2011, one year from the date of inception. There will be an exchange of the notional amounts at maturity. The foreign exchange rates included in this forward contract are based upon observable market data, but are not quoted market prices, and therefore, the forward currency forward contract is considered a Level 2 liability on the fair value hierarchy.

The carrying value of our current financial instruments, which include cash and cash equivalents, marketable securities, trade accounts receivable, accounts payable and short-term debt approximates fair value because of the short-term maturity of these financial instruments. At August 31, 2011 and May 31, 2011, the fair value of our long-term debt was estimated using active market quotes, based on our current incremental borrowing rates for similar types of borrowing arrangements, which are considered to be Level 2 inputs. Based on the analysis performed, the fair value and the carrying value of our financial instruments and long-term debt as of August 31, 2011 and May 31, 2011 are as follows:
