Level 3 Assets

Power Supply Agreement

During the year ended December 31, 2021, the Company recorded a derivative asset related to its Power Supply Agreement. The Power Supply Agreement was classified as a derivative asset and measured at fair value on the date of the Company’s acquisition of Whinstone, with changes in fair value recognized in change in fair value of derivative asset in operating income or loss on the accompanying consolidated statements of operations. The contract was not designated as a hedging instrument. Prior to the Whinstone Acquisition, the Company did not have any derivative contracts. The estimated fair value of the Company’s derivate asset is classified in Level 3 of the fair value hierarchy due to the significant unobservable inputs utilized in the valuation. Specifically, our discounted cash flow estimation models contain quoted commodity exchange spot and forward prices and are adjusted for basis spreads for load zone-to-hub differentials through the term of the Power Supply Agreement, which ends in December 2030. The discount rate utilized of approximately 21% includes observable market inputs, but also includes unobservable inputs based on qualitative judgment related to company-specific risk factors.

The terms of the Power Supply Agreement require margin-based collateral, calculated as exposure resulting from fluctuations in the market cost rate of electricity versus the fixed price stated in the contract. The margin-based collateral requirement to the Company is zero as of December 31, 2021.

Level 3 Liabilities

Business Combination Contingent Consideration

The Company recorded a Level 3 financial liability during the year ended December 31, 2021, relating to the contingent consideration arrangement arising from the acquisition of Whinstone. Contingent consideration represents an obligation of the Company to transfer cash to the Seller when Whinstone realizes or receives a benefit from utilization of certain defined power credits. See Note 4, “Acquisitions”. The Company estimated the fair value of the contingent consideration using a discounted cash flow analysis, which includes estimates of both the timing and amounts of potential future power credits. These estimates were determined using the Company’s historical consumption quantities and patterns combined with management’s expectations of its future consumption requirements, which require significant judgment and depend on various factors outside the Company’s control, such as construction delays. The discount rate of approximately 2.5% includes observable market inputs, such as TXU’s parent company’s Standard & Poor’s credit rating of BB, but also includes unobservable inputs such as interest rate spreads, which were estimated based on qualitative judgment related to company-specific risk factors. Specifically, due to the power credits being subordinated obligations for TXU’s parent, we used one credit rating lower than BB in our yield curve to estimate a reasonable interest rate spread to determine the cost of debt input. The significant assumptions used to estimate fair value of the derivative contract include a discount rate of 21%, which reflected the nature of the contract as it relates to the risk and uncertainty of the estimated future mark-to-market adjustments, forward price curves of the power supply, broker/dealer quotes and other similar data obtained from quoted market prices or independent pricing vendors. Although these estimates are based on management’s best knowledge of current events, the estimates could change significantly from period to period. Actual results that differ from the assumptions used and any changes to the significant assumptions and unobservable inputs used could have a material impact on future results of operations.

Changes in Level 3 assets and liabilities measured at fair value on a recurring basis

Unobservable inputs were used to determine the fair value of positions that the Company has classified within the Level 3 category. Unrealized gains and losses associated with the asset within the Level 3 category includes changes in fair value that were attributable to unobservable (e.g., changes in unobservable long-dated volatilities) inputs.

Additionally, during the year ended December 31, 2021, power sales back to ERCOT through its demand response programs of $6.5 million were recorded in change in fair value of derivative asset in the consolidated statements of operations. There were no Level 3 assets for the year ended December 31, 2020.

The following table presents the changes in the estimated fair value of our liability for contingent consideration measured using significant unobservable inputs (Level 3) for the year ended December 31, 2021 (in thousands):

	Contingent Consideration Liability
Balance as of January 1, 2021	$	-
Acquisition of Whinstone		82,953

For the year ended December 31, 2021 the change in Level 3 liabilities measured at fair value was approximately $1.0 million. There were no Level 3 liabilities for the year ended December 31, 2020. Our estimated liability for contingent consideration represents potential payments of additional consideration for the Whinstone Acquisition, payable if Whinstone realizes or receives a benefit from utilization of certain defined power credits. Changes in the fair value of contingent consideration are recorded in the consolidated statements of operations within change in fair value of contingent consideration.

There were no transfers of financial instruments between Level 1, Level 2 and Level 3 during the period presented.

Assets and Liabilities Not Measured at Fair Value on a Recurring Basis

In addition to assets and liabilities that are measured at fair value on a recurring basis, we also measure certain assets and liabilities at fair value on a nonrecurring basis. Our non-financial assets, including goodwill, intangible assets, operating lease right of use assets, and property, plant and equipment, are measured at fair value when there is an indication of impairment and the carrying amount exceeds the asset’s projected undiscounted cash flows. These assets are recorded at fair value only when an impairment charge is recognized.
