Bargain purchase gain (3)
$9.6 
(1) The gross amount of trade receivables was collected subsequent to the acquisition date.
(2) The fair value of Property, plant and equipment was estimated by applying the income approach and utilizing the discounted cash flow method. This methodology assesses the value of tangible assets by computing the anticipated cash flows expected to be generated by the respective assets.
(3) The bargain purchase gain represents the excess of the fair value of the underlying net assets acquired and liabilities assumed over the purchase consideration and is included in “Other non-operating income (expense), net” in the condensed consolidated statement of operations and comprehensive income. The bargain purchase gain is non-taxable and primarily related to the seller being a single-asset corporation aiming to monetize its investment in the facility subsequent to closing a tax equity deal.

$16.1 
(1) The fair value of Property, plant and equipment was estimated by applying the income approach and utilizing the discounted cash flow method. This methodology assesses the value of tangible assets by computing the anticipated cash flows expected to be generated by the respective assets.
(2) Other long-term liability is related to the long-term electricity PPA described above, and is amortized over the term of the PPA. The fair value of the long-term liability represents a PPA price that is relatively lower than the related prevailing market price, and was estimated by applying the income approach and utilizing the With and Without method.
(3) Goodwill is primarily related to the expected synergies, potential cost savings in operations as a result of the purchase transaction as well as potential future enhancements to the geothermal asset. The goodwill is allocated to the Electricity segment and is deductible for tax purposes.
