NOTE 9. FAIR VALUE

The Company has established a fair value hierarchy which prioritizes the inputs to the valuation techniques used to measure fair value into three levels. These levels are determined based on the lowest level input that is significant to the fair value measurement. Levels within the hierarchy are defined as follows:

Level 1 - Unadjusted quoted prices in active markets for identical assets and liabilities;

Level 2 - Quoted prices for similar assets and liabilities in active markets (other than those included in Level 1) which are observable, either directly or indirectly; and

Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

The following tables summarize information regarding the Company's financial assets and financial liabilities that were measured at fair value on a recurring basis:

(1) Investment deposit accounts are short-term in nature, and the value is determined by principal plus interest. The investment portfolio mix can change each period based on the Company's assessment of investment options.

(2) Derivative assets and liabilities classified as Level 1 are commodity futures contracts valued based on quoted market prices in the London Metal Exchange or New York Mercantile Exchange. Amounts in Level 2 are based on broker quotes in the over-the-counter market. Further discussion regarding the Company's use of derivative instruments and the classification of the assets and liabilities is included in Note 8, Derivatives and Risk Management.

There were no material non-recurring fair value remeasurements during the three months ended November 30, 2017.

The carrying values of the Company's short-term items, including the deferred purchase price of accounts receivable, documentary letters of credit and notes payable, approximate fair value due to their short-term nature.

The carrying values and estimated fair values of the Company's financial assets and liabilities that are not required to be measured at fair value on the unaudited condensed consolidated balance sheets were as follows:



		November 30, 2017				August 31, 2017
(in thousands)	Fair Value Hierarchy	Carrying Value		Fair Value		Carrying Value		Fair Value
2027 Notes ⁽¹⁾	Level 2	$	300,000	$	307,431	$	300,000	$	314,286
2023 Notes ⁽¹⁾	Level 2	330,000		339,824		330,000		340,052
2022 Term Loan ⁽²⁾	Level 2	150,000		150,000		150,000		150,000
