__________________________________ (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 9, Derivatives. As of August 31, 2022, the Company had one Level 3 commodity derivative. The Company entered into its second and third Level 3 commodity derivatives in September 2022 and January 2023, respectively, with the same counterparty as the first Level 3 commodity derivative. Both the second and third Level 3 commodity derivatives will begin to settle in January 2025. The fair value estimates 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 ("floating rate"). The floating rate is the only significant unobservable input used in the Company's discounted cash flow models. The following table summarizes the floating rate used to measure the fair value of the Level 3 commodity derivatives at February 28, 2023 and August 31, 2022:
|  | Floating rate (PLN)
|  | Low |  | High |  | Average
February 28, 2023 |  | 575.51 |  |  | 1,298.53 |  |  | 793.65 |
August 31, 2022 |  | 460.11 |  |  | 1,298.53 |  |  | 717.22 |
Fair value, net derivative asset (liability) measured on recurring basis, unobservable input reconciliation | 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 included in other comprehensive income ("OCI") in the three and six months ended February 28, 2023 and 2022.
