NOTE 13 – Derivative Instruments
Warrant Liabilities
In June 2022, 234,399 Private Placement Warrants were exercised on cashless basis at an exercise price of $11.50 per share in exchange for a total of 100,009 shares of Class A Common Stock. As of June 30, 2022, 6,536,601 Private Placement Warrants remain outstanding, and each is exercisable to purchase one share of Class A Common Stock or, in certain circumstances, one Class A Opco Unit and corresponding share of Class B Common Stock. The Private Placement Warrants expire on September 15, 2026, or earlier upon redemption or liquidation. Private Placement Warrants are nonredeemable so long as they are held by the initial purchasers or their permitted transferees. The outstanding Private Placement Warrants continue to be held by the initial purchasers or their permitted transferees as of June 30, 2022.
The Private Placement Warrants contain exercise and settlement features that preclude them from being classified within stockholders’ equity, and therefore are recognized as derivative liabilities. The Company recognizes the warrant instruments as liabilities at fair value with changes in fair value included within gain (loss) on warrants and derivative contracts in the Company’s consolidated statements of operations. Derivative warrant liabilities are classified as non-current liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.
The fair value of the Private Placement Warrants is estimated using the Black-Scholes option pricing model (a Level 3 measurement).
The Company used the following assumptions to estimate the fair value of the Private Placement Warrants:
June 30, 2022 December 31, 2021
Stock price
$ 15.53 $ 18.28
Exercise price
$ 11.50 $ 11.50
49.5  % 46.0  %
Expected term (years)
4.2 4.7
Risk-free interest rate
3.0  % 1.2  %
The change in the fair value of the warrant liabilities is recognized in gain (loss) on warrants and derivative contracts in the consolidated statement of operations. The changes in the warrant liabilities for the six months ended June 30, 2022 are as follows:

Natural Gas Swap
In conjunction with the Business Combinations, the Company assumed a natural gas variable to fixed priced swap agreement entered into by Aria. The Company is the fixed price payer under the swap agreement that provides for monthly net settlements through the termination date of June 30, 2023. The agreement was intended to manage the risk associated with changing commodity prices. The agreement has a remaining notional of 219,000 MMBtu as of June 30, 2022.
Changes in the fair values and realized gains (losses) for the natural gas swap are recognized in gain (loss) on warrants and derivative contracts in the consolidated statement of operations. Valuation of the natural gas swap was calculated by discounting future net cash flows that were based on a forward price curve for natural gas over the remaining life of the contract (a Level 2 measurement), with an adjustment for each counterparty’s credit rate risk.
Interest Rate Swap
In December 2021, the Company entered into an interest rate swap that locks in payments of a fixed interest rate of 1.094% in exchange for a floating interest rate that resets monthly based on LIBOR. The interest rate swap was not designated as a hedging instrument, and net gains and losses are recognized currently in gain (loss) on warrants and derivative contracts. The interest rate swap notional was $107.9 million as of June 30, 2022 and declines over the term of the swap to $94.9 million at the December 2024 contract termination date.
