__________________________________ (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 the 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 11, Derivatives. The fair value estimate of the Level 3 commodity derivative is based on an internally developed discounted cash flow model primarily utilizing unobservable inputs in 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 model. The following table summarizes the floating rate during 2022 and 2021:
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 derivative recognized in the consolidated statements of comprehensive income. The fluctuation in energy rates over time may cause volatility in the fair value estimate and is the primary reason for the unrealized gains and losses in other comprehensive income ("OCI") in 2022, 2021 and 2020.
