Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited consolidated condensed financial statements have been prepared in accordance with generally accepted accounting principles ("GAAP") in the U.S. and in accordance with the instructions for Form 10-Q and Article 10 of Regulation S-X for interim financial information. Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial reporting. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The consolidated balance sheet on December 31, 2021 has been derived from audited financial statements but does not include all the information and notes required by GAAP for complete financial statements. Certain reclassifications were made to the consolidated financial statements for the prior period to conform to current period presentation. The interim financial information contained herein should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2021 included in the Company's Annual Report on Form 10-K, as filed with the SEC on February 22, 2022. Operating results for the quarter ended March 31, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022 or for any future interim periods. Use of Estimates The preparation of unaudited consolidated condensed financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures related thereto at the date of the unaudited consolidated condensed financial statements and the reported amounts of revenue and expenses during the reporting period. Management evaluates these estimates and assumptions on an ongoing basis. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited interim consolidated condensed financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from estimates. Financial Instruments The Company’s financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, and variable-rate senior debt, are carried at cost, which approximates their fair value because of either the short-term maturity or competitive interest rates assigned to these financial instruments. The fair values of the Company’s other debt instruments fall within level 1 or level 2 of the fair value hierarchy. The Company considers all highly liquid investments, including commercial paper issued by counterparties with Standard & Poor's rating of A1+ or higher, with maturity of three months or less when purchased to be cash and cash equivalents. The Company did not have any investments in commercial paper on March 31, 2022 or December 31, 2021. Income Taxes MIH is a limited liability company treated as a partnership for tax purposes.

The subsidiaries of the Company are owned by an intermediate holding company organized as a limited liability company and classified as a corporation for tax purposes. The intermediate holding company files a consolidated federal income tax return and a combined Hawaii state income tax return. Recently Issued Accounting Standards In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of Effects of Reference Rate Reform on Financial Reporting, which provides practical expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by the amendments in this update apply only to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued as a result of reference rate reform. In January 2021, the FASB also issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope, which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. These amendments are elective and apply to all entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. These amendments are not applicable to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022. ASU No. 2020-04 and ASU No. 2021-01 are effective as of March 12, 2020 and through December 31, 2022, and may be applied to contract modifications and hedging relationships from the beginning of an interim period that includes or is subsequent to March 12, 2020. The Company is currently evaluating the impact of adoption on its financial statements and related disclosures.
