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 within Note 1, Nature of Operations and Summary of Significant Accounting Policies, to the consolidated financial statements in the 2023 Form 10-K.

The Company presents the fair value of its derivative contracts on a net-by-counterparty basis when a legal right to offset exists under an enforceable netting agreement. The following table summarizes 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. Derivatives classified as Level 3 are described below. Further discussion regarding the Company's use of derivative instruments is included in Note 8, Derivatives.

The fair value estimate of the Level 3 commodity derivatives are based on internally developed discounted cash flow models primarily utilizing unobservable inputs for which there is little or no market data. The Company forecasts future energy rates using a range of historical prices (the "floating rate"), which is the only significant unobservable input used in the Company's discounted cash flow models. Significantly higher or lower floating rates could have resulted in a material difference in the fair value measurement. The following table summarizes the range of floating rates used to measure the fair value of the Level 3 commodity derivatives at February 29, 2024 and August 31, 2023, which are applied uniformly across each of our Level 3 commodity derivatives:

Below is a reconciliation of the beginning and ending balances of the Level 3 commodity derivatives recognized in the condensed consolidated statements of comprehensive income. The fluctuation in energy rates over time causes volatility in the fair value estimates and is the primary reason for unrealized gains and losses included in OCI in the three and six months ended February 29, 2024 and February 28, 2023, respectively.

There were no material non-recurring fair value remeasurements during the three or six months ended February 29, 2024 or February 28, 2023.

The carrying values of the Company's short-term items, including documentary letters of credit and notes payable, approximate fair value.

The carrying value and fair value of the Company's long-term debt, including current maturities, excluding other borrowings and finance leases, was $1.0 billion and $935.6 million, respectively, at February 29, 2024, and $1.0 billion and $900.9 million, respectively, at August 31, 2023. The Company estimates these fair values based on Level 2 of the fair value hierarchy using indicated market values. The Company's other borrowings contain variable interest rates, and as a result, their carrying values approximate fair values.
