6. Fair Value Measurements

The Company determines a fair value measurement based on the assumptions a market participant would use in pricing an asset or liability. ASC 820, Fair Value Measurements and Disclosures (“ASC 820”), establishes a three level hierarchy making a distinction between market participant assumptions based on (i) unadjusted quoted prices for identical assets or liabilities in an active market (Level 1), (ii) quoted prices in markets that are not active or inputs that are observable either directly or indirectly for substantially the full term of the asset or liability (Level 2), and (iii) prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement (Level 3).

The following table presents information about assets and liabilities required to be carried at fair value and measured on a recurring basis as of May 31, 2011 and August 31, 2010:


	Fair Value Measurements as of:
	May 31, 2011				August 31, 2010
	Level 1		Total Fair Value		Level 1		Total Fair Value
Assets:
Cash and cash equivalents	$	160.8	$	160.8	$	191.0	$	191.0
Short-term investments (1)		0.8		0.8		1.3		1.3
Long-term investments (1)		1.3		1.3		1.8		1.8

Liabilities:
Deferred compensation plan (2)		2.1		2.1		3.1		3.1


(1)		The Company maintains certain investments that generate returns that offset changes in certain liabilities related to deferred compensation arrangements.

(2)		The Company maintains a self-directed, non-qualified deferred compensation plan primarily for certain retired executives and other highly compensated employees.

The Company utilizes valuation methodologies to determine the fair values of its financial assets and liabilities in conformity with the concepts of “exit price” and the fair value hierarchy as prescribed in ASC 820. All valuation methods and assumptions are validated at least quarterly to ensure the accuracy and relevance of the fair values. There were no material changes to the valuation methods or assumptions used to determine fair values during the current period.

The Company used the following valuation methods and assumptions in estimating the fair value of the following assets and liabilities:

Cash and cash equivalents are classified as Level 1 assets. The carrying amounts for cash reflect the assets’ fair values, and the fair values for cash equivalents are determined based on quoted market prices.

Short-term and long-term investments are classified as Level 1 assets. These investments consist primarily of publicly traded marketable equity securities and fixed income securities, and the fair values are obtained through market observable pricing.

Deferred compensation plan liabilities are classified as Level 1 within the hierarchy. The fair values of the liabilities are directly related to the valuation of the long-term investments held in trust for the plan. Hence, the carrying value of the deferred compensation liability represents the fair value of the investment assets.

The Company does not have any assets or liabilities that are carried at fair value and measured on a recurring basis classified as Level 2 or Level 3 assets or liabilities. In addition, no transfers between the levels of the fair value hierarchy occurred during the current fiscal period. In the event of a transfer in or out of Level 1, the transfers would be recognized on the date of occurrence.

Disclosures of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate that value are required each reporting period in addition to any financial instruments carried at fair value on a recurring basis as prescribed by ASC 825, Financial Instruments, (“ASC 825”). In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.

The carrying values and estimated fair values of certain of the Company’s financial instruments were as follows at May 31, 2011 and August 31, 2010:


	May 31, 2011				August 31, 2010
	Carrying Value		Fair Value		Carrying Value		Fair Value
Liabilities:
Senior unsecured public notes, net of unamortized discount	$	349.4	$	364.9	$	349.3	$	384.5
Industrial revenue bond		4.0		4.0		4.0		4.0

Senior unsecured public notes are carried at the outstanding balance, including bond discounts, as of the end of the reporting period. Fair value is estimated based on the discounted future cash flows using rates currently available for debt of similar terms and maturity.

The industrial revenue bond is carried at the outstanding balance as of the end of the reporting period. The industrial revenue bond is a tax-exempt, variable-rate instrument that resets on a weekly basis, and, therefore, the Company estimates that the face amount of the bond approximates fair value as of May 31, 2011.

ASC 825 excludes certain financial instruments and all nonfinancial instruments from its disclosure requirements. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. In many cases, the fair value estimates cannot be substantiated by comparison to independent markets, nor can the disclosed value be realized in immediate settlement of the instruments. In evaluating the Company’s management of liquidity and other risks, the fair values of all assets and liabilities should be taken into consideration, not only those presented above.
