| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation. Prior to the Separation on April 3, 2020, our historical financial statements were prepared on a standalone combined basis and were derived from the consolidated financial statements and accounting records of our former parent, UTC. For the period subsequent to April 3, 2020, our financial statements are presented on a consolidated basis as the Company became a standalone public company (collectively, the financial statements for all periods presented, including the historical results of the Company prior to April 3, 2020, are now referred to as "Consolidated Financial Statements" to reflect this change). They have been prepared in accordance with the instructions to Form 10-K. Prior to the Separation on April 3, 2020, the Consolidated Statements of Operations included all revenues and costs directly attributable to Otis, including costs for facilities, functions and services used by Otis. Costs for certain functions and services performed by centralized UTC organizations were directly charged to Otis based on specific identification when possible or based on a reasonable allocation driver such as net sales, headcount, usage or other allocation methods. All charges and allocations for facilities, functions and services performed by UTC organizations have been deemed settled in cash by Otis to UTC in the period in which the cost was recorded on the Consolidated Statements of Operations. Current and deferred income taxes were determined based on the standalone results of Otis. However, because the Company was included in our former parent UTC’s tax group in certain jurisdictions, the Company's actual tax balances may differ from those reported. The Company's portion of its domestic income taxes and certain income taxes for jurisdictions outside the U.S. are deemed to have been settled in the period the related tax expense was recorded prior to the Separation. The Consolidated Financial Statements include the accounts of Otis and its controlled subsidiaries, as well as entities where Otis has a variable interest and is the primary beneficiary as defined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, Consolidation . The factors we use to determine the primary beneficiary of a variable interest entity ("VIE") may include decision authority, control over management of day-to-day operations and the amount of our equity investment in relation to others' investments. All significant intracompany accounts and transactions within the Company have been eliminated in the preparation of the Consolidated Financial Statements. Certain amounts for prior years have been reclassified to conform to the current year presentation, which are immaterial. Use of Estimates. The preparation of the Consolidated Financial Statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities. In addition, estimates and assumptions may impact the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. We assessed certain accounting matters that generally require consideration of forecasted financial information in the context of the information reasonably available to us and the unknown future impacts of coronavirus ("COVID-19") as of December 31, 2021 and 2020, and through the date of this report. The accounting matters assessed included, but were not limited to, our allowance for credit losses, the carrying value of our goodwill and other long-lived assets, financial assets and revenue recognition. While there was not a material impact to our Consolidated Financial Statements as of and for the years ended December 31, 2021 and 2020 resulting from our assessments of these matters, future assessment of our current expectations at that time of the magnitude and duration of COVID-19, as well as other factors, could result in material impacts to our Consolidated Financial Statements in future reporting periods. Risks and Uncertainties. As the global COVID-19 pandemic continues and the economic recovery is ongoing, the Company continues to closely monitor and manage the impact of the COVID-19 pandemic on its business globally. It is difficult to estimate at this time the duration and extent of the continued impact of the pandemic and ongoing economic recovery on the Company's business, financial position, cash flow and results of operations. The results of our operations and overall financial performance were impacted during the years ended December 31, 2021 and 2020, including impacts to customer demand for our new equipment, maintenance and repair and modernization businesses, cancellations or delays of customer orders, customer liquidity constraints and related credit reserves, and supplier and raw material capacity constraints, delays and related costs. Primarily in 2020, there were also temporary closures and reduced capacity of our operations, limited new equipment job site closures and challenges in accessing units to provide maintenance and repair services that also impacted our results. Due to existing conditions and uncertainty, COVID-19 and ongoing economic recovery could have an impact on our business, cash flow and results of operations into 2022. The extent of the impact will depend largely on future developments, which are highly uncertain, including the severity of the outbreak and variants of COVID-19, efficacy, availability and distribution of vaccines, actions taken by government authorities to further contain the outbreak or address its impact and its longer-term impacts on the global economy, among other factors. Cash and Cash Equivalents. Cash and cash equivalents includes cash on hand, demand deposits and short-term cash investments that are highly liquid in nature and have original maturities of three months or less. Restricted Cash. In certain circumstances we are required to maintain cash deposits with certain banks with respect to contractual or other legal obligations, and therefore the use of these cash deposits for general operational purposes is restricted. Restricted cash as of December 31, 2 021 is primarily cash of $1.9 billion required to be held in escrow to fund the Tender Offer, which is expected to be completed in 2022. The non-current portion of restricted cash is $2 million as of December 31, 2021 and 2020, and is included in Other assets on the Consolidated Balance Sheets. Accounts Receivable. The Company records accounts receivables when the right to consideration becomes unconditional. We regularly evaluate the collectability of our accounts receivable and maintain reserves for expected credit losses. See Note 6, "Accounts Receivable, Net" for additional information on the Company's policy for evaluation of expected credit losses. We do not believe that accounts receivable represent significant concentrations of credit risk because of the diversified portfolio of individual customers and geographic areas. Retainage and Unbilled Receivables. Current an d long-term accounts receivable as of December 31, 2021 and 2020 include retainage of $75 million and $61 million, respectively, and unbilled receiv ables of $109 million and $104 million, respectively. Retainage represents amounts that, pursuant to the applicable contract, are not due until after project completion and acceptance by the customer. Unbilled receivables represent revenues that are earned but may not be currently billable to the customer under the terms of the contract. These items are expected to be billed and collected in the ordinary course of business. Unbilled receivables where we have an unconditional right to payment are included in Accounts receivable, net as of December 31, 2021 and 2020. Customer Financing Notes Receivable. Through financing arrangements with our customers, we extend payment terms, which are generally not more than one year in duration. Factoring. The Company may sell certain trade accounts and notes receivable to lending institutions to manage credit risk. Financial assets sold under these arrangements are excluded from Accounts receivable, net in the Company’s Consolidated Balance Sheets at the time of sale if the Company has surrendered control over the related assets. Whether control has been relinquished requires, among other things, an evaluation of relevant legal considerations and an assessment of the nature and extent of the Company’s continuing involvement with the assets transferred. Gains and losses stemming from transfers reported as sales are included in Interest expense (income), net in the accompanying Consolidated Statements of Operations. Contract Assets and Liabilities. Contract assets and liabilities represent the difference in the timing of revenue recognition from receipt of cash from our customers and billings. Contract assets reflect revenue recognized and performance obligations satisfied in advance of customer billing. Performance obligations partially satisfied in advance of customer billings are included in Contract assets, current. Contract liabilities relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts. See Note 4, "Contract Assets and Liabilities" for further discussion of contract assets and liabilities. Inventories. Inventories are stated at the lower of cost or estimated realizable value and are primarily based on a first-in, first-out (“FIFO”) method. Valuation reserves for excess, obsolete and slow-moving inventory are estimated by comparing the inventory levels of individual parts to both future sales forecasts or production requirements and historical usage rates in order to identify inventory where the resale value or replacement value is less than inventoriable cost. See Note 7, "Inventories, Net" for further details of the inventories by classification. Fixed Assets. Fixed assets, including software capitalized for internal-use, are recorded at cost. Depreciation of fixed assets is computed over the fixed assets' useful lives on a straight-line basis, unless another systematic and rational basis is more representative of the fixed asset's pattern of use. See Note 8, "Fixed Assets" for further details of useful lives. Internal-use software. The Company capitalizes direct costs of services used in the development of, and external software acquired for use as, internal-use software. Amounts capitalized are amortized over a period ranging from three Asset Retirement Obligations. The Company records the fair value of legal obligations associated with the retirement of tangible long-lived assets in the period in which the legal obligations are determined to exist. Upon initial recognition of a liability, the Company capitalizes the cost of the asset retirement obligation by increasing the carrying amount of the related long-lived asset. Over time, the liabilit y is adjusted for c hanges in its present value and the capitalized cost is depreciated over the useful life of the related asset. Fair Value of Financial Instruments. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels: Level I – Quoted prices for identical instruments in active markets. Level II – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level III – Instruments whose significant value drivers are unobservable. The carrying amount of current trade receivables, accounts payable and accrued expenses approximates fair value due to the short maturity (less than one year) of the instruments. Equity Method Investments. Entities in which we have the ability to exercise significant influence, but do not control, are accounted for under the equity method of accounting and are included in Other assets on the Consolidated Balance Sheets. Under this method of accounting, our share of the net earnings or losses of the investee entity is included in Other income (expense), net in the Consolidated Statements of Operations since the activities of the investee entity are closely aligned with the operations of the Company. We evaluate our equity method investments whenever events or changes in circumstance indicate that the carrying amounts of such investments may be impaired. If a decline in the value of an equity method investment is determined to be other than temporary, a loss is recorded in earnings in the current period. Business Combinations. We account for transactions that are classified as business combinations in accordance with the FASB ASC Topic 805: Business Combinations . Once a business is acquired, the fair values of the identifiable assets acquired and liabilities assumed are d etermined with the excess cost recorded to goodwill. As required, preliminary fair values are determined once a business is acquired, with the final determination of the fair values being completed within the one-year measurement period from the date of acquisition. Goodwill, Intangible Assets and Long-Lived Assets. Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Intangible assets consist of service portfolios, patents, trademarks/trade names, customer relationships and other intangible assets. Acquired intangible assets are recognized at fair value during acquisition accounting and then amortized to Cost of products and services sold and Selling, general and administrative over the applicable useful lives. Goodwill and Indefinite-Lived Intangible Assets. Goodwill and intangible assets deemed to have indefinite lives are not amortized. Goodwill and indefinite-lived intangible assets are subject to impairment testing annually or when a triggering event occurs using the guidance and criteria described in FASB ASC Topic 350: Intangibles – Goodwill and Other . This testing compares carrying values to fair values and, when appropriate, the carrying value of these assets is reduced to fair value. We test goodwill for impairment at a level within the Company referred to as the reporting unit, which is one level below the operating segment level. When testing goodwill for impairment, the Company may first assess qualitative factors. If an initial qualitative assessment identified that it is more likely than not that the fair value of a reporting unit is less than its carrying value, additional quantitative testing is performed. The Company may also elect to skip the qualitative testing and proceed directly to the quantitative testing. If the quantitative testing indicates that goodwill is impaired, an impairment charge is recognized based on the difference between the reporting unit's carrying value and its fair value. When it is determined that a quantitative analysis is required, the Company primarily utilizes a discounted cash flow methodology to calculate the fair value of its reporting units. The Company completed its most recent annual impairment testing as of July 1, 2021, and determined in the qualitative assessment that quantitative testing is not necessary. There were no triggering events since the annual impairment test. Finite-Lived Intangible Assets and Long-Lived Assets. Useful lives of finite-lived intangible assets are estimated based upon the nature of the intangible asset. These intangible assets are amortized based on the pattern in which the economic benefits of the intangible assets are consumed or if straight-line amortization approximates the pattern of economic benefit, a straight-line amortization method may be used. The range of estimated useful lives is as follows: Purchased service portfolios 5 to 25 years Patents, trademarks/trade names 4 to 40 years Customer relationships and other 1 to 20 years The Company evaluates the potential impairment of long-lived assets, including finite-lived intangible assets whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. If the carrying value of other long-lived assets h eld and used exceeds the sum of the undiscounted expected future cash flows, the carrying value is written down to fair value. See Note 8, "Fixed Assets" and Note 9, " Business Acquisitions, Goodwill and Intangible Assets " for additional information regarding intangible assets and other long-lived asse ts. Income Taxes. In the ordinary course of business, there is inherent uncertainty in quantifying our income tax positions. We assess our income tax positions and record tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances and information available at the reporting date. For those tax positions where it is more-likely-than-not that a tax benefit will be sustained, we have recorded the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more-likely-than-not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. Where applicable, associated interest expense has also been recognized. We recognize accrued interest related to unrecognized tax benefits in Interest expense (income), net. Penalties, if incurred, would be recognized as a component of Income tax expense. The U.S. Tax Cuts and Jobs Act ("TCJA") subjects the Company to a tax on Global Intangible Low-Taxed Income (“GILTI”). GILTI is a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. We account for GILTI as a period cost as incurred. Income taxes as presented in the Consolidated Financial Statements of the Company for periods prior to the Separation attribute current and deferred income taxes of our former parent, UTC, to the Company's stand-alone financial statements in a manner that is systematic, rational and consistent with the asset and liability method prescribed by FASB ASC Topic 740: Income Taxes (“ASC 740”). Accordingly, the Company's income tax provision for periods prior to the Separation was prepared following the separate return method. The separate return method applies ASC 740 to the stand-alone financial statements of each member of the consolidated group as if the group members were a separate taxpayer and a stand-alone enterprise. The calculation of our income taxes on a separate return basis requires a considerable amount of judgment and use of both estimates and allocations. As a result, actual transactions included in the consolidated financial statements of UTC may not be included in the Consolidated Financial Statements of the Company. Similarly, the tax treatment of certain items reflected in the Consolidated Financial Statements of the Company may not be reflected in the consolidated financial statements and tax returns of UTC. Therefore, such items as net operating losses, credit carry-forwards and valuation allowances may exist in the stand-alone financial statements that may or may not exist in UTC’s consolidated financial statements. As such, the income taxes of the Company as presented in the Consolidated Financial Statements prior to the Separation may not be indicative of the income taxes that the Company will report in the future. See Note 5, "Related Parties" and Note 16, "Income Taxes" for additional information. Revenue Recognition. We recognized revenue in accordance with FASB ASC Topic 606: Revenue from Contracts with Customers and its related amendments, (referred to, collectively, as "ASC 606”). The Company's revenue streams include new equipment, maintenance and repair, and modernization. New equipment, modernization and repair services revenue are recognized over time as we are enhancing an asset the customer controls. Maintenance revenue is recognized on a straight-line basis over the life of the maintenance contract. New Equipment, Modernization and Repair services. For new equipment and modernization transactions, equipment and installation are typically procured in a single contract providing the customer with a complete installed elevator or escalator unit. The combination of equipment and installation promises are typically a single performance obligation. For repair services, the customer typically contracts for specific short-term services which form a single performance obligation. For these performance obligations, revenue is recognized over time using costs incurred to date relative to total estimated costs at completion to measure progress. Incurred costs represent work performed, which corresponds with and best depicts transfer of control or the enhancement of the customer’s assets. Contract costs included in the calculation are comprised of labor, materials, subcontractors’ costs or other direct costs and indirect costs, which include indirect labor costs. Specific to new equipment and modernization arrangements, the Company, based on project progression, reviews cost estimates on significant contracts on a quarterly basis, and for others, no less frequently than annually or when circumstances change and warrant a modification to a previous estimate. These estimates form the basis for the amount of revenue to be recognized and include the latest updated total transaction price, costs and risks for each contract. These estimates for our ongoing contracts may materially change due to the change and completions of the contract scopes, cost estimates and customers' plans, among other factors. For performance obligations recognized under the cost to cost method, we record changes in contract estimates using the cumulative catch-up method. Modifications are recognized as a cumulative catch-up or treated as a separate accounting contract if the modification adds distinct goods or services and the modification is priced at its stand-alone selling price. Maintenance. Our customers purchase maintenance contracts which include services such as required periodic maintenance procedures, preventive services and stand ready obligations to remediate issues with the elevator/escalator when and if they arise. Given the continuous nature of these services throughout the year, we recognize revenue on maintenance contracts on a straight-line basis which aligns with the cost profile of these services. Contractual changes are typically recognized prospectively as most modifications are extensions of the existing arrangement. Transaction Price Considerations. Our contracts typically include fixed payments which are generally received as we progress under our contracts. As a result, we have not identified any significant financing elements in our contract, and our contracts do not have significant estimates related to variable consideration except in the case of a project having an underlying performance issue, which is rare. In situations where multiple performance obligations in a single contract (e.g. , new equipment and maintenance) e xist, the transaction price is allocated to each performance obligation in proportion to their stand-alone selling prices. Estimates are made to account for changes in transaction prices attributable to pricing disputes that occur subsequent to the inception of contracts, based upon historical experience and the status of contracts. Certain costs to obtain or fulfill contracts . Certain costs to obtain or fulfill a contract with a customer must be capitalized, to the extent recoverable from the associated contract margin, and subsequently amortized as the products or services are delivered to the customer. Sales commissions related to new equipment, modernization and maintenance contracts, excluding renewals, are capitalized as contract fulfillment costs and are amortized consistent with the pattern of transfer of the goods or services. Customer contract costs, which do not qualify for capitalization as contract fulfillment costs, are expensed as incurred. Loss Contracts. Loss provisions on contracts are recognized to the extent that estimated contract costs exceed the estimated consideration from the products contemplated under the contractual arrangement. For new commitments, we generally record loss provisions at contract inception. For existing commitments, anticipated losses on contractual arrangements are recognized in the period in which losses become probable. Remaining Performance Obligations ("RPO"). RPO represents the aggregate amount of total contract transaction price that is unsatisfied or partially unsatisfied. As of December 31, 2021, our total RPO was approximately $17.1 billion. Of the total RPO as of December 31, 2021, we expect approximately 89% will be recognized as sales over the following 24 months. Additional disclosure required by ASC 606 is provided in Note 23, "Segment Financial Data", including disaggregation of revenue into categories that depict how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Self-Insurance. The Company is primarily self-insured for a number of risks including, but not limited to, workers’ compensation, general liability, automobile liability and employee-related healthcare benefits. The Company has obtained insurance coverage for amounts exceeding individual and aggregate loss limits. The Company accrues for known future claims and incurred but not reported losses wit hin Accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets, totaling $287 million and $299 million as of December 31, 2021 and 2020, respectively. Derivatives and Hedging Activity. We have used derivative instruments, principally forward contracts, to help manage certain foreign currency and commodity price exposures. Derivative instruments are viewed as risk management tools by us and are not used for trading or speculative purposes. By their nature, all financial instruments involve market and credit risks. We enter into derivative and other financial instruments with major investment grade financial institutions and have policies to monitor the credit risk of those counterparties. We limit counterparty exposure and concentration of risk by diversifying counterparties. While there can be no assurance, we do not anticipate any material non-performance by any of these counterparties. Designated Derivative Instruments. Derivatives used for hedging purposes may be designated and effective as a hedge of the identified risk exposure at the inception of the contract. All derivative instruments are recorded on the Consolidated Balance Sheets at fair value. Derivatives used to hedge foreign currency denominated balance sheet items and commodity prices for materials recognized in cost of sales, and are reported directly in earnings along with offsetting transaction gains and losses on the items being hedged. Derivatives used to hedge forecasted cash flows associated with foreign currency commitmen ts or forecasted commodity purchases m ay be accounted for as cash flow hedges, as deemed appropriate. Gains and losses on derivatives designated as cash flow hedges are recorded in other comprehensive income (loss), net of tax and reclassified to earnings as a component of product sales or expenses, as applicable, when the hedged transaction occurs. Gains and losses on derivatives designated as cash flow hedges are recorded in Other operating activities, net within the Consolidated Statement of Cash Flows. To the extent that a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hed ging relationship is recorded currently in earnings in the period it occurs. Additional information pertaining to net investment hedging is included in Note 18, "Financial Instruments". Non-designated Derivative Instruments. To the extent the hedge accounting criteria are not applied, the foreign currency forward contracts and commodity price contracts are utilized as economic hedges and changes in the fair value of these contracts are recorded currently in earnings in the period in which they occur. Additional information pertaining to these contracts is included in Note 18, "Financial Instruments". In addition, the Company periodically enters into sales contracts denominated in currencies other than the functional currency of the parties to the transaction. The Company accounts for these transactions separately valuing the embedded derivative component of these contracts. The changes in the fair value of these embedded derivatives are recorded in Other income (expense), net in th e Consolidated Statements of Operations . For the years ended December 31, 2021, 2020 and 2019, we recognized a gain of $1 million, a loss of $3 million and a loss of $27 million, respectively, due to the changes in fair value of embedded derivatives. Environmental. Environmental investigatory, remediation, operating and maintenance costs are accrued when it is probable that a liability has been incurred and the amount can be reasonably estimated. The most likely cost to be incurred is accrued based on an evaluation of currently available facts with respect to each individual site, including current laws, regulations and prior remediation experience. Whe re no amount within a range of estimates is more likely, the minimum is accrued. Liabilities with fixed or reliably determinable future cash payments are discounted. Accrued environmental liabilities are not reduced by potential insurance reimbursements. See Note 22, "Contingent Liabilities" for additional details on the environmental remediation activities. Research and Development. These costs are expensed in the period incurred and are shown on a separate line of the Consolidated Statements of Operations. Research and development expenses, covering research and the advancement of potential new and improved products and their uses, primarily include salaries and other employment costs. Other Income (Expense), Net. Other income (expense), net i ncludes the impact of changes in the fair value and settlement of derivatives, gains or losses on sale of businesses and fixed assets, earnings from equity method investments, fair value changes on equity securities, impairments, non-recurring Separation-related expenses, gains on insurance recoveries and certain other infrequent operating income and expense items. Foreign Exchange. We conduct business in many different currencies and, accordingly, are subject to the inherent risks associated with foreign exchange rate movements. The financial position and results of operations of substantially all of our foreign subsidiaries are measured using the local currency as the functional currency. Foreign currency denominated assets and liabilities are translated into U.S. Dollars at the exchange rates existing at the respective balance sheet dates, and income and expense items are translated at the average exchange rates during the respective periods. The aggregate effects of translating the balance sheets of these subsidiaries are deferred within Accumulated other comprehensive income (loss). Pension and Postretirement Obligations. Guidance under FASB ASC Topic 715: Compensation – Retirement Benefits requires balance sheet recognition of the overfunded or underfunded status of pension and postretirement benefit plans. Under this guidance, actuarial gains and losses, prior service costs or credits and any remaining transition assets or obligations that have not been recognized under previous accounting standards must be recognized in other comprehensive income (loss), net of tax effects, until they are amortized as a component of net periodic benefit cost. Pension and postretirement obligation balances and related costs reflected within the Consolidated Financial Statem ents include both costs directly attributable to plans dedicated to Otis, as well as an alloc |
