Organization and Description of Business Macquarie Infrastructure Corporation (MIC) is a Delaware corporation formed on May 21, 2015. MICs predecessor, Macquarie Infrastructure Company LLC, was formed on April 13, 2004. Macquarie Infrastructure Corporation, both on an individual entity basis and together with its consolidated subsidiaries, is referred to in these financial statements as the Company or MIC. MIC is externally managed by Macquarie Infrastructure Management (USA) Inc. (the Manager) pursuant to the terms of a Management Services Agreement, subject to the oversight and supervision of the Board. Six of the eight members of the Board, and all of the members of each of the Company's Audit, Compensation and Nominating and Governance committees, are independent and have no affiliation with Macquarie. The Manager is a member of the Macquarie Group of companies comprising Macquarie Group Limited and its subsidiaries and affiliates worldwide. Macquarie Group Limited is headquartered in Australia and is listed on the Australian Securities Exchange. The Company owns its businesses through its direct wholly-owned subsidiary MIC Ohana Corporation, the successor to Macquarie Infrastructure Company Inc. The Company owns and operates a portfolio of infrastructure and infrastructure-like businesses that provide services to corporations, government agencies and individual customers primarily in the United States (U.S.). The Company's operations are organized into four segments:  International-Matex Tank Terminals (IMTT): a business providing bulk liquid storage and handling services to third-parties at 17 terminals in the U.S. and two in Canada;  Atlantic Aviation: a provider of jet fuel, terminal, aircraft hangaring and other services primarily to operators of general aviation (GA) jet aircraft at 70 airports throughout the U.S.;  MIC Hawaii: comprising a company that processes and distributes gas and provides related services (Hawaii Gas) and several smaller businesses collectively engaged in efforts to reduce the cost and improve the reliability and sustainability of energy in Hawaii; and  Corporate and Other: comprising MIC Corporate (holding company headquarters in New York City) and a shared services center in Plano, Texas. Effective October 1, 2018, the Bayonne Energy Center (BEC) and substantially all of the Companys portfolio of solar and wind power generation businesses were classified as discontinued operations and the Companys Contracted Power segment was eliminated. All periods reflect this change. In July 2019, the Company completed the sales of its wind power generating portfolio and all but one of the assets in its solar power generating portfolio. The sale of the remaining solar facility closed during September 2019. On January 1, 2019, the Company also classified its majority interest in a renewable power development business as a discontinued operation, the sale of which closed in July 2019. A remaining relationship with a third-party developer of renewable power facilities has been reported as a component of Corporate and Other through the expiration of the relationship in July 2019. For additional information, see Note 4, Discontinued Operations and Dispositions. In October 2019, in addition to the active management of the existing portfolio of businesses, the Board resolved to simultaneously pursue strategic alternatives including potentially a sale of the Company or its operating businesses as a means of unlocking additional value for stockholders. The Company has not set a timetable for completing any transaction and there can be no assurance that any transaction(s) will occur on favorable terms or at all.
