Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business Overview	Business Overview Otis (as defined below) is the world’s largest elevator and escalator manufacturing, installation and service company. Our operations are classified into two segments: New Equipment and Service. Through the New Equipment segment, we design, manufacture, sell and install a wide range of passenger and freight elevators, as well as escalators and moving walkways, for residential, commercial and infrastructure projects. The Service segment provides maintenance and repair services for both our products and those of other manufacturers, and provides modernization services to upgrade elevators and escalators. On November 26, 2018, United Technologies Corporation, subsequently renamed to Raytheon Technologies Corporation on April 3, 2020 ("UTC" or "RTX", as applicable), announced its intention to spin-off its Otis reportable segment and its Carrier reportable segment into two separate publicly-traded companies (the "Separation"). On April 3, 2020, the Company became an independent publicly-traded company through a pro-rata distribution of 0.5 shares of Common Stock for every share of UTC common stock held at the close of business on the record date of March 19, 2020 ("Distribution"). Otis began to trade as a separate public company (New York Stock Exchange ("NYSE"): OTIS) on April 3, 2020. Unless the context otherwise requires, references to "Otis", "we", "us", "our" and "the Company" refer to (i) Otis Worldwide Corporation's business prior to the Separation and (ii) Otis Worldwide Corporation and its subsidiaries following the Separation, as applicable. References to "UTC" relate to pre-Separation matters, and references to "RTX" relate to post-Separation matters. Sale of Russia Business The Company sold its business in Russia during 2022. See Note 9, "Business Acquisitions, Dispositions, Goodwill and Intangible Assets" for additional information regarding the sale of our Russia business. Zardoya Otis Tender Offer The Company previously announced its Tender Offer to acquire all of the issued and outstanding shares of Zardoya Otis not owned by the Company in cash, and its intention to delist the shares of Zardoya Otis from the Spanish stock exchanges subsequent to the Tender Offer (the "Tender Offer"). The price per share of the Tender Offer was €7.07 in cash as of March 31, 2022, after adjustments for dividends paid. The Tender Offer was approved by the Spanish regulator on February 28, 2022. As a result of the Tender Offer approval, the issued and outstanding shares of Zardoya Otis owned by Euro Syns, S.A. ("Euro Syns") were reclassified to current liabilities as Forward purchase agreement, and the remaining shares not owned by the Company were deemed redeemable at the option of the other shareholders and were reclassified from Noncontrolling interest to Redeemable noncontrolling interest on our Consolidated Financial Statements. The difference between the historical noncontrolling interest carrying value in the balance sheet and the fair value of the Tender Offer was recorded to Accumulated deficit. The results of the Tender Offer were announced on April 7, 2022, with tenders, including Euro Syns' shares, of 45.49% of the shares outstanding accepted, resulting in the Company owning 95.51% of Zardoya Otis. The shares tendered to the Company were settled in cash on April 12, 2022 for approximately €1.5 billion from the Company's restricted cash held in escrow. The acquisition and settlement of the remaining issued and outstanding shares of Zardoya Otis not owned by the Company occurred in the second quarter for approximately €150 million. The automatic delisting of Zardoya Otis shares occurred on May 9, 2022. Zardoya Otis was then renamed Otis Mobility S.A. ("Otis Mobility"). The Company owned a controlling interest and had operational control of Otis Mobility (formerly Zardoya Otis) as of and for the years ended December 31, 2022, 2021 and 2020, and therefore its financial results are included in our Consolidated Financial Statements. The Company owned 50.02% of Otis Mobility prior to the Tender Offer and 100% after completion of the Tender Offer. See Note 10, "Borrowings and Lines of Credit" for additional information regarding financing agreements entered into by the Company and its subsidiaries in connection with the Tender Offer.
