Acquisitions	Acquisitions Gulf Power - On January 1, 2019, NEE acquired the outstanding common shares of Gulf Power, a rate-regulated electric utility under the jurisdiction of the FPSC. Gulf Power serves more than 460,000 customers in eight counties throughout northwest Florida, has approximately 9,400 miles of transmission and distribution lines and owns approximately 2,300 MW of net generating capacity. The purchase price included approximately $4.47 billion in cash consideration less estimated post-closing working capital adjustments of $104 million and the assumption of approximately $1.3 billion of Gulf Power debt. The cash purchase price was funded through $4.5 billion of borrowings by NEECH in December 2018 under certain short-term bi-lateral term loan agreements (see Note 10); the proceeds of which borrowings were restricted and included in noncurrent other assets on NEE's condensed consolidated balance sheet at December 31, 2018. Under the acquisition method, the purchase price was allocated to the assets acquired and liabilities assumed on January 1, 2019 based on their fair value. The approval by the FPSC of Gulf Power's rates, which is intended to allow Gulf Power to collect from retail customers total revenues equal to Gulf Power's costs of providing service, including a reasonable rate of return on invested capital, is considered a fundamental input in measuring the fair value of Gulf Power's assets and liabilities and, as such, NEE concluded that the carrying values of all assets and liabilities recoverable through rates are representative of their fair values. As a result, NEE acquired assets of approximately $5.3 billion, primarily relating to property, plant and equipment of $4.0 billion and regulatory assets of $490 million, and assumed liabilities of approximately $3.5 billion, including $1.3 billion of long-term debt, $640 million of regulatory liabilities and $590 million of deferred income taxes. The excess of the purchase price over the fair value of assets acquired and liabilities assumed resulted in approximately $2.6 billion of goodwill which has been recognized on NEE's condensed consolidated balance sheet at March 31, 2019. Goodwill associated with the Gulf Power acquisition will be reflected within Corporate and Other and, for impairment testing, will be included in the Gulf Power reporting unit. The goodwill arising from the transaction represents expected benefits from continued expansion of NEE's regulated business mix and the indefinite life of Gulf Power's service territory franchise. In connection with the acquisition, operating right-of-use assets and lease liabilities were recorded primarily related to a purchased power agreement; such amounts each totaled approximately $248 million at March 31, 2019. The operating leases have fixed payments with expiration dates ranging from late 2019 to 2023. At March 31, 2019, expected lease payments over the remaining terms of the operating leases were approximately $260 million with no one year being material. Gulf Power's operating leases did not have a material impact to NEE's condensed consolidated statements of income or cash flows. Trans Bay Cable, LLC - In March 2019, a wholly owned subsidiary of NextEra Energy Transmission, LLC received FERC approval to acquire the outstanding membership interests of Trans Bay Cable, LLC for approximately $1.05 billion, including the assumption of debt. The acquisition is expected to close in 2019, pending approval of the California Public Utilities Commission.
