Organization, Consolidation and Presentation of Financial Statements [Abstract]
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION Moody’s is a global integrated risk assessment firm that empowers organizations and investors to make better decisions. Moody’s reports in two reportable segments: MIS and MA. MIS publishes credit ratings and provides assessment services on a wide range of debt obligations, programs and facilities, and the entities that issue such obligations in markets worldwide, including various corporate, financial institution and governmental obligations, and structured finance securities. MA is a global provider of: i) data and information; ii) research and insights; and iii) decision solutions, which help companies make better and faster decisions. MA leverages its industry expertise across multiple risks such as credit, market, financial crime, supply chain, catastrophe and climate to deliver integrated risk assessment solutions that enable business leaders to identify, measure and manage the implications of interrelated risks and opportunities. These interim financial statements have been prepared in accordance with the instructions to Form 10-Q and should be read in conjunction with the Company’s consolidated financial statements and related notes in the Company’s 2021 annual report on Form 10-K filed with the SEC on February 22, 2022. The results of interim periods are not necessarily indicative of results for the full year or any subsequent period. In the opinion of management, all adjustments (including normal recurring accruals) considered necessary for a fair presentation of financial position, results of operations and cash flows at the dates and for the periods presented have been included. The year-end consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. Certain reclassifications have been made to prior period amounts to conform to the current presentation. Adoption of New Accounting Standards On January 1, 2022, the Company adopted ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" ("ASU No. 2021-08"). This ASU requires companies to apply the definition of a performance obligation under ASC Topic 606 to recognize and measure contract assets and contract liabilities (i.e., deferred revenue) relating to contracts with customers that are acquired in a business combination. The adoption of this ASU will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under ASC Topic 606. Accordingly, upon adoption, the Company will no longer be required to adjust acquired deferred revenue to fair value in business combination transactions. The amendments in ASU No. 2021-08 are applied prospectively and have been applied to business combination transactions completed subsequent to January 1, 2022. COVID-19 The COVID-19 pandemic has not had a material adverse impact on the Company's reported results to date and is currently not expected to have a material adverse impact on its near-term outlook. However, Moody's is unable to predict the longer-term impact that the pandemic may have on its business, future results of operations, financial position or cash flows due to numerous uncertainties. Russia/Ukraine Conflict The Company is closely monitoring the impact of the ongoing Russia/Ukraine conflict on all aspects of its business. In response to the conflict, the Company is no longer conducting commercial operations in Russia for both MIS and MA and is complying with all applicable regulatory restrictions set forth by the jurisdictions in which Moody's operates. Furthermore, the Company also has withdrawn MIS credit ratings on Russian entities. While Moody's Russian operations and net assets are not material, broader global market volatility, which partially relates to uncertainties surrounding the conflict, has contributed to an adverse impact on rated issuance volumes in 2022. The Company is unable to predict either the near-term or longer-term impact that the conflict may have on its financial position and operating results due to numerous uncertainties regarding the severity and duration of the conflict and its broader potential macroeconomic impact. Reclassification of Previously Reported Revenue by LOB In the first quarter of 2022, the Company realigned its revenue by LOB reporting structure for the MA operating segment to enhance insight and transparency into this business. As of January 1, 2022, the MA LOBs have been realigned from RD&A and ERS to: – Decision Solutions (DS) - provides software and workflow tools for specific use cases (banking, insurance, KYC/KYS, CRE and structured finance solutions). This LOB utilizes components from the Data & Information and Research & Insights LOBs to provide integrated risk solutions; – Research & Insights (R&I) - provides models, scores, expert insights and commentary. This LOB includes: credit research; credit models and analytics; and economics data and models; and – Data & Information (D&I) - provides vast data sets on companies and securities via data feeds and data applications products. Prior year revenue by LOB disclosures have been reclassified to conform to the new LOB reporting structure, which is presented in Note 2.

In the MIS segment, excluding MIS Other, transaction revenue represents the initial rating of a new debt issuance as well as other one-time fees while recurring revenue represents the recurring monitoring fees of a rated debt obligation and/or entities that issue such obligations, as well as revenue from programs such as commercial paper, medium-term notes and shelf registrations. In MIS Other, transaction revenue represents revenue from professional services and recurring revenue represents subscription-based revenues. In the MA segment, recurring revenue represents subscription-based revenues and software maintenance revenue. Transaction revenue in MA represents perpetual software license fees and revenue from software implementation services, risk management advisory projects, and training and certification services.

In addition, for certain MA arrangements, the timing of when the Company has the unconditional right to consideration and recognizes revenue occurs prior to invoicing the customer. The following table presents the Company's unbilled receivables, which are included within accounts receivable, net, at September 30, 2022 and December 31, 2021: As of September 30, 2022 As of December 31, 2021 MIS MA MIS MA Unbilled Receivables $ 381 $ 147 $ 386 $ 152 Deferred revenue The Company recognizes deferred revenue when a contract requires a customer to pay consideration to the Company in advance of when revenue related to that contract is recognized. This deferred revenue is relieved when the Company satisfies the related performance obligation and revenue is recognized. Significant changes in the deferred revenue balances during the three and nine months ended September 30, 2022 and 2021 are as follows: Three Months Ended September 30, 2022 Three Months Ended September 30, 2021 MIS MA Total MIS MA Total Balance at June 30, $ 347 $ 1,019 $ 1,366 $ 368 $ 867 $ 1,235 Changes in deferred revenue Revenue recognized that was included in the deferred revenue balance at the beginning of the period (110) (480) (590) (118) (484) (602) Increases due to amounts billable excluding amounts recognized as revenue during the period 82 389 471 85 393 478 Increases due to acquisitions during the period — — — — 89 89 Effect of exchange rate changes (5) (9) (14) (2) (12) (14) Total changes in deferred revenue (33) (100) (133) (35) (14) (49) Balance at September 30, $ 314 $ 919 $ 1,233 $ 333 $ 853 $ 1,186 Nine Months Ended September 30, 2022 Nine Months Ended September 30, 2021 MIS MA Total MIS MA Total Balance at December 31, $ 296 $ 1,039 $ 1,335 $ 313 $ 874 $ 1,187 Changes in deferred revenue Revenue recognized that was included in the deferred revenue balance at the beginning of the period (186) (883) (1,069) (200) (814) (1,014) Increases due to amounts billable excluding amounts recognized as revenue during the period 218 819 1,037 224 713 937 Increases due to acquisitions during the period — 1 1 — 93 93 Effect of exchange rate changes (14) (57) (71) (4) (13) (17) Total changes in deferred revenue 18 (120) (102) 20 (21) (1) Balance at September 30, $ 314 $ 919 $ 1,233 $ 333 $ 853 $ 1,186 Deferred revenue - current $ 238 $ 917 $ 1,155 $ 247 $ 852 $ 1,099 Deferred revenue - non-current $ 76 $ 2 $ 78 $ 86 $ 1 $ 87 For the MIS segment, the changes in the deferred revenue balance during the three and nine months ended September 30, 2022 were primarily related to the significant portion of contract renewals that occurred during the first quarter of 2022 and are generally recognized over a one year period. For the MA segment, the decrease in deferred revenue for the three months ended September 30, 2022 was primarily due to the recognition of annual subscription and maintenance billings from December 2021 and January 2022. For the nine months ended September 30, 2022, the decrease in the deferred revenue balance is attributable to recognition of revenues related to the aforementioned December 2021 billings and unfavorable changes in FX translation rates being mostly offset by the impact of the high concentration of billings in the first quarter of 2022. Remaining performance obligations Remaining performance obligations in the MIS segment largely reflect deferred revenue related to monitoring fees for certain structured finance products, primarily CMBS, where the issuers can elect to pay the monitoring fees for the life of the security in advance. As of September 30, 2022, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $103 million. The Company expects to recognize into revenue approximately 20% of this balance within one year, approximately 50% of this balance between one to five years and the remaining amount thereafter. With respect to the remaining performance obligations for the MIS segment, the Company has applied a practical expedient set forth in ASC Topic 606 permitting the omission from the amounts stated above relating to unsatisfied performance obligations for contracts with an original expected length of one year or less. Remaining performance obligations in the MA segment include both amounts recorded as deferred revenue on the balance sheet as of September 30, 2022 as well as amounts not yet invoiced to customers as of September 30, 2022, largely reflecting future revenue related to signed multi-year arrangements for hosted and installed subscription-based products. As of September 30, 2022, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $3.1 billion. The Company expects to recognize into revenue approximately 60% of this balance within one year, approximately 30% of this balance between one to two years and the remaining amount thereafter.

STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION Presented below is a summary of the stock-based compensation cost and associated tax benefit included in the accompanying consolidated statements of operations: Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Stock-based compensation cost $ 46 $ 41 $ 130 $ 127 Tax benefit $ 10 $ 8 $ 30 $ 29 During the first nine months of 2022, the Company granted 0.1 million employee stock options, which had a weighted average grant date fair value of $84.00 per share. The Company also granted 0.6 million shares of restricted stock in the first nine months of 2022, which had a weighted average grant date fair value of $321.70 per share. Both the employee stock options and restricted stock generally vest ratably over four years. Additionally, the Company granted 0.1 million shares of performance-based awards whereby the number of shares that ultimately vest are based on the achievement of certain non-market-based performance metrics of the Company over three years. The weighted average grant date fair value of these awards was $310.62 per share. The following weighted average assumptions were used in determining the fair value using the Black-Scholes option-pricing model for options granted in 2022: Expected dividend yield 0.86 % Expected stock volatility 27 % Risk-free interest rate 1.91 % Expected holding period 5.6 years Unrecognized stock-based compensation expense at September 30, 2022 was $18 million and $260 million for stock options and unvested restricted stock, respectively, which is expected to be recognized over a weighted average period of 2.1 years and 2.6 years, respectively. Additionally, there was $34 million of unrecognized stock-based compensation expense relating to the aforementioned non-market-based performance-based awards, which is expected to be recognized over a weighted average period of 1.6 years. The following table summarizes information relating to stock option exercises and restricted stock vesting: Nine Months Ended 2022 2021 Exercise of stock options: Proceeds from stock option exercises $ 6 $ 20 Aggregate intrinsic value $ 7 $ 44 Tax benefit realized upon exercise $ 2 $ 10 Number of shares exercised (1) — 0.2 Vesting of restricted stock: Fair value of shares vested $ 174 $ 193 Tax benefit realized upon vesting $ 41 $ 43 Number of shares vested 0.5 0.7 Vesting of performance-based restricted stock: Fair value of shares vested $ 50 $ 28 Tax benefit realized upon vesting $ 7 $ 4 Number of shares vested 0.2 0.1

INCOME TAXES

INCOME TAXES	9 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Moody’s effective tax rate (ETR) was 20.5% and 23.4% for the three months ended September 30, 2022 and 2021, respectively, and 21.3% and 20.2% for the nine months ended September 30, 2022 and 2021, respectively. The 2.9% decrease in the ETR for the three months ended September 30, 2022 compared to the same period in the prior year was primarily due to lower pre-tax income, which increases the percentage impact of net beneficial discrete items, as well as a favorable mix of earnings in the jurisdictions in which Moody’s operates. The 1.1% increase in the ETR for the nine months ended September 30, 2022 compared to the same period in the prior year was primarily due to tax benefits realized upon resolution of UTPs during 2021 that did not recur to the same extent in 2022 and a non-deductible loss associated with the Company no longer conducting commercial operations in Russia. The Company’s year-to-date 2022 income tax expense differs from the tax computed by applying its estimated annual effective tax rate to the pre-tax earnings primarily due to the following items recognized in 2022: i) Excess Tax Benefits from stock-based compensation of $19 million; and ii) net reductions in UTPs of $20 million related to the resolution of UTPs. The Company classifies interest related to UTPs in interest expense, net in its consolidated statements of operations. Penalties, if incurred, would be recognized in other non-operating (expense) income, net. The Company had a decrease in its UTPs of $28 million (net of federal tax) during the third quarter of 2022 and a decrease in its UTPs of $80 million ($75 million net of federal tax) during the nine months of 2022, which primarily related to the aforementioned resolution of UTPs. Moody’s Corporation and subsidiaries are subject to U.S. federal income tax as well as income tax in various state, local and foreign jurisdictions. The Company’s U.S. federal income tax returns for 2017 through 2020 are currently under examination and 2021 remains open to examination. The Company’s New York State tax returns for 2017 through 2018 and New York City tax returns for 2015 through 2018 are currently under examination. The Company’s U.K. tax returns for 2012 through 2020 remain open to examination. For ongoing audits, it is possible the balance of UTPs could decrease in the next twelve months as a result of the settlement of such audits, which might involve the payment of additional taxes, the adjustment of certain deferred taxes and/or the recognition of tax benefits. It is also possible that new issues will be raised by tax authorities which could necessitate increases to the balance of UTPs. As the Company is unable to predict the timing or outcome of these audits, it is unable to estimate the amount of changes to the balance of UTPs at this time. However, the Company believes that it has adequately provided for its financial exposure relating to all open tax years, by tax jurisdiction, in accordance with the applicable provisions of Topic 740 of the ASC regarding UTPs. The following table shows the amount the Company paid for income taxes: Nine Months Ended September 30, 2022 2021 Income taxes paid $ 394 $ 501 In August 2022, the U.S. Congress passed the Inflation Reduction Act, which included a corporate minimum tax on book earnings of 15%, an excise tax on corporate share repurchases of 1%, and certain climate change and energy tax credit incentives. The adoption of a corporate minimum tax of 15% is not expected to impact Moody’s ETR. The excise tax of 1% on corporate share buybacks will not have an impact on the Company’s ETR for the years 2022 or 2023.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS	ACQUISITIONS The material business combination described below is accounted for using the acquisition method of accounting whereby assets acquired and liabilities assumed were recognized at fair value or other values set forth in U.S. GAAP on the date of the transaction. Any excess of the purchase price over the fair value of the assets acquired and liabilities assumed was recorded to goodwill. Goodwill typically results through expected synergies from combining operations of an acquiree and an acquirer, anticipated new customer acquisition and products, as well as from intangible assets that do not qualify for separate recognition. RMS On September 15, 2021, the Company acquired 100% of RMS, a global provider of climate and natural disaster risk modeling and analytics. The cash payment was funded with new debt financing and a combination of U.S. and offshore cash on hand. The acquisition will expand Moody’s insurance data and analytics business and accelerate the development of the Company’s global integrated risk capabilities to address the next generation of risk assessment. The table below details the total consideration relating to the acquisition: Cash paid at closing $ 1,922 Replacement equity compensation awards 5 Total consideration $ 1,927 Shown below is the purchase price allocation, which summarizes the fair value of the assets and liabilities assumed, at the date of acquisition: Cash (1) $ 55 Accounts receivable 38 Other current assets (1) 12 Property and equipment, net 13 Operating lease right-of-use assets 64 Intangible assets: Customer relationships (23 year useful life) $ 518 Product technology (7 year useful life) 212 Trade name (9 year useful life) 49 Total intangible assets (18 year weighted average useful life) 779 Goodwill (1) 1,357 Deferred tax assets, net 50 Other assets 99 Liabilities: Accounts payable and accrued liabilities (1) $ (96) Deferred revenue (89) Operating lease liabilities (68) Deferred tax liabilities, net (214) Uncertain tax positions (1) (71) Other liabilities (2) Total liabilities (540) Net assets acquired $ 1,927 (1) During the third quarter of 2022, the Company adjusted the purchase price allocation pursuant to the receipt of additional information from the sellers relating to RMS's pre-acquisition income taxes. These adjustments included a decrease to UTPs of $25 million along with other immaterial adjustments. These adjustments resulted in a corresponding decrease in goodwill of $19 million. Goodwill The goodwill recognized as a result of this acquisition includes, among other things, the value of combining the complementary product portfolios of Moody's and RMS, which is expected to extend the Company's reach into new market segments. The goodwill also includes the combined company's ability to accelerate technology innovations into new product adjacencies (leveraging RMS's team of data scientists, modelers and software engineers) as well as combining RMS's products with Moody’s core data and analytics offerings to provide holistic integrated risk solutions. Goodwill, of which $1,267 million and $90 million has been assigned to the MA and MIS segments, respectively, is not deductible for tax purposes. The amount of goodwill allocated to the MIS segment relates to the integration of certain of RMS's models/processes into the Company's ESG solutions offerings. Other assets in the table above includes an indemnification asset of $95 million related to UTPs assumed in the transaction, for which the Company expects to be indemnified by the sellers in the event of an unfavorable outcome. Transaction costs Transaction costs incurred in the year ended December 31, 2021 directly related to the RMS acquisition were $22 million and were recorded in SG&A expenses in the statement of operations. Supplementary Unaudited Pro Forma Information Supplemental information on an unaudited pro forma basis is presented below for the three and nine months ended September 30, 2021 as if the acquisition of RMS occurred on January 1, 2020. The pro forma financial information is presented for comparative purposes only and is based on certain estimates and assumptions, which the Company believes to be reasonable but not necessarily indicative of future results of operations or the results that would have been reported if the acquisition had been completed at January 1, 2020. The unaudited pro forma information includes amortization of acquired intangible assets, based on the purchase price allocation and an estimate of useful lives reflected above, and incremental financing costs resulting from the acquisition, net of income tax, which was estimated using the weighted average statutory tax rates in effect in the jurisdiction for which the pro forma adjustment relates.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES The Company is exposed to global market risks, including risks from changes in FX rates and changes in interest rates. Accordingly, the Company uses derivatives in certain instances to manage the aforementioned financial exposures that occur in the normal course of business. The Company does not hold or issue derivatives for speculative purposes. Derivatives and non-derivative instruments designated as accounting hedges: Fair Value Hedges Interest Rate Swaps The Company has entered into interest rate swaps to convert the fixed interest rate on certain of its long-term debt to a floating interest rate based on the 3-month LIBOR, 6-month LIBOR, and SOFR. The purpose of these hedges is to mitigate the risk associated with changes in the fair value of the long-term debt, thus the Company has designated these swaps as fair value hedges. The fair value of the swaps is adjusted quarterly with a corresponding adjustment to the carrying value of the debt. The changes in the fair value of the swaps and the underlying hedged item generally offset and the net cash settlements on the swaps are recorded each period within interest expense, net in the Company’s consolidated statements of operations. The following table summarizes the Company’s interest rate swaps designated as fair value hedges: Notional Amount Hedged Item Nature of Swap As of September 30, 2022 As of December 31, 2021 Floating Interest Rate 2017 Senior Notes due 2023 Pay Floating/Receive Fixed $ — $ 250 3-month USD LIBOR 2017 Senior Notes due 2028 Pay Floating/Receive Fixed $ 500 $ 500 3-month USD LIBOR 2020 Senior Notes due 2025 Pay Floating/Receive Fixed $ 300 $ 300 6-month USD LIBOR 2014 Senior Notes due 2044 Pay Floating/Receive Fixed $ 300 $ 300 3-month USD LIBOR 2018 Senior Notes due 2048 Pay Floating/Receive Fixed $ 300 $ 300 3-month USD LIBOR 2018 Senior Notes due 2029 (1) Pay Floating/Receive Fixed $ 400 $ — SOFR 2022 Senior Notes due 2052 (2) Pay Floating/Receive Fixed $ 500 $ — SOFR 2022 Senior Notes due 2032 (3) Pay Floating/Receive Fixed $ 250 $ — SOFR Total $ 2,550 $ 1,650 (1) Executed in the first quarter of 2022.

Restructuring and Related Activities [Abstract]
RESTRUCTURING	RESTRUCTURING On June 30, 2022, the chief executive officer of Moody’s approved a restructuring program (the “2022 - 2023 Geolocation Restructuring Program”) for which the scope was expanded in October 2022, prior to the filing of this quarterly report on Form 10-Q. T he Company estimates that the program will result in annualized savings of $100 million to $135 million per year. This program relates to the Company's post-COVID-19 geolocation strategy and includes the rationalization and exit of certain real estate leases and a reduction in staff, including the relocation of certain job functions from their current locations. The exit from certain leased office spaces is expected to begin late in 2022 or early 2023 and is expected to result in $50 million to $70 million of pre-tax charges to either terminate or sublease the affected real estate leases. The program also includes $75 million to $100 million of pre-tax personnel-related restructuring charges, an amount that includes severance and related costs primarily determined under the Company’s existing severance plans. The savings generated from the 2022 - 2023 Geolocation Restructuring Program are expected to strengthen the Company's operating margin, with a portion being deployed to support strategic investments, including the Company's Workplace of the Future program and employee retention initiatives. The 2022 - 2023 Geolocation Restructuring Program is expected to be substantially complete by the end of 2023. Cash outlays associated with this program are expected to be $75 million to $100 million, which are expected to be paid through 2024. On December 22, 2020, the chief executive officer of Moody’s approved a restructuring program (the “2020 MA Strategic Reorganization Restructuring Program”) that the Company estimates will result in annualized savings of $20 million per year. This program relates to a strategic reorganization in the MA reportable segment consisting of severance and related costs primarily determined under the Company’s existing severance plans. The 2020 MA Strategic Reorganization Restructuring Program resulted in a total of $19 million in pre-tax charges and was substantially completed in the first half of 2021. Cash outlays associated with this program are expected to be $20 million, which will be paid through 2022.

The following are descriptions of the methodologies utilized by the Company to estimate the fair value of its derivative contracts, mutual funds and money market mutual funds: Derivatives: In determining the fair value of the derivative contracts in the table above, the Company utilizes industry standard valuation models. Where applicable, these models project future cash flows and discount the future amounts to a present value using spot rates, forward points, currency volatilities, interest rates as well as the risk of non-performance of the Company and the counterparties with whom it has derivative contracts. The Company established strict counterparty credit guidelines and only enters into transactions with financial institutions that adhere to these guidelines. Accordingly, the risk of counterparty default is deemed to be minimal. Mutual funds: The mutual funds in the table above are deemed to be equity securities with readily determinable fair values with changes in the fair value recognized through net income under ASC Topic 321. The fair value of these instruments is determined using Level 1 inputs as defined in the ASC Topic 820.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES Given the nature of the Company's activities, Moody’s and its subsidiaries are subject to legal and tax proceedings, governmental, regulatory and legislative investigations, subpoenas and other inquiries, and claims and litigation by governmental and private parties that are based on ratings assigned by MIS or that are otherwise incidental to the Company’s business. Moody’s and MIS also are subject to periodic reviews, inspections, examinations and investigations by regulators in the U.S. and other jurisdictions, any of which may result in claims, legal proceedings, assessments, fines, penalties or restrictions on business activities. Moody’s also is subject to ongoing tax audits as addressed in Note 4 to the condensed consolidated financial statements. Management periodically assesses the Company’s liabilities and contingencies in connection with these matters based upon the latest information available. For claims, litigation and proceedings and governmental investigations and inquiries not related to income taxes, the Company records liabilities in the consolidated financial statements when it is both probable that a liability has been incurred and the amount of loss can be reasonably estimated and periodically adjusts these as appropriate. When the reasonable estimate of the loss is within a range of amounts, the minimum amount of the range is accrued unless some higher amount within the range is a better estimate than another amount within the range. In instances when a loss is reasonably possible but uncertainties exist related to the probable outcome and/or the amount or range of loss, management does not record a liability but discloses the contingency if material. As additional information becomes available, the Company adjusts its assessments and estimates of such matters accordingly. Moody’s also discloses material pending legal proceedings pursuant to SEC rules and other pending matters as it may determine to be appropriate.

SEGMENT INFORMATION

SEGMENT INFORMATION	9 Months Ended

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company is organized into two operating segments: MIS and MA and accordingly, the Company reports in two reportable segments: MIS and MA. The MIS segment consists of five LOBs. The CFG, FIG, PPIF and SFG LOBs generate revenue principally from fees for the assignment and ongoing monitoring of credit ratings on debt obligations and the entities that issue such obligations in markets worldwide. The MIS Other LOB primarily consists of financial instruments pricing services in the Asia-Pacific region, ICRA non-ratings revenue and revenue from providing ESG research, data and assessments. The MA segment develops a wide range of products and services that support the risk management activities of institutional participants in global financial markets. The MA segment consists of three LOBs - Decision Solutions, Research and Insights, and Data and Information. Revenue for MIS and expenses for MA include intersegment fees charged to MA for the rights to use and distribute content, data and products developed by MIS. Additionally, revenue for MA and expenses for MIS include an intersegment fee charged to MIS from MA for certain MA products and services utilized in MIS’s ratings process. These intersegment fees are generally based on the market value of the products and services being transferred between the segments. Overhead expenses include costs such as rent and occupancy, information technology and support staff such as finance, human resources and legal. Such costs and corporate expenses that exclusively benefit one segment are fully charged to that segment. For overhead costs and corporate expenses that benefit both segments, costs are allocated to each segment based on the segment’s share of full-year 2018 actual revenue which comprises a “Baseline Pool” established in 2019, which will remain fixed over time. In subsequent periods, incremental overhead costs (or reductions thereof) will be allocated to each segment based on the prevailing shares of total revenue represented by each segment. “Eliminations” in the following table represent intersegment revenue/expense. Moody’s does not report the Company’s assets by reportable segment, as this metric is not used by the chief operating decision maker to allocate resources to the segments. Consequently, it is not practical to show assets by reportable segment. Financial Information by Segment The table below shows revenue and Adjusted Operating Income by reportable segment. Adjusted Operating Income is a financial metric utilized by the Company’s chief operating decision maker to assess the profitability of each reportable segment. Refer to Note 2 for further details on the components of the Company’s revenue.

Adoption of New Accounting Standards	Adoption of New Accounting Standards On January 1, 2022, the Company adopted ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" ("ASU No. 2021-08"). This ASU requires companies to apply the definition of a performance obligation under ASC Topic 606 to recognize and measure contract assets and contract liabilities (i.e., deferred revenue) relating to contracts with customers that are acquired in a business combination. The adoption of this ASU will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under ASC Topic 606. Accordingly, upon adoption, the Company will no longer be required to adjust acquired deferred revenue to fair value in business combination transactions. The amendments in ASU No. 2021-08 are applied prospectively and have been applied to business combination transactions completed subsequent to January 1, 2022.

Revenues - Expected Recognition

Revenues - Expected Recognition Period for Remaining Performance Obligations (Detail) $ in Millions	9 Months Ended
	Sep. 30, 2022 USD ($)
Revenue, Remaining Performance Obligation, Expected Timing of Satisfaction [Line Items]
Revenue, remaining performance obligation, expected timing of satisfaction, explanation	Remaining performance obligations in the MIS segment largely reflect deferred revenue related to monitoring fees for certain structured finance products, primarily CMBS, where the issuers can elect to pay the monitoring fees for the life of the security in advance. As of September 30, 2022, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $103 million. The Company expects to recognize into revenue approximately 20% of this balance within one year, approximately 50% of this balance between one to five years and the remaining amount thereafter. With respect to the remaining performance obligations for the MIS segment, the Company has applied a practical expedient set forth in ASC Topic 606 permitting the omission from the amounts stated above relating to unsatisfied performance obligations for contracts with an original expected length of one year or less.Remaining performance obligations in the MA segment include both amounts recorded as deferred revenue on the balance sheet as of September 30, 2022 as well as amounts not yet invoiced to customers as of September 30, 2022, largely reflecting future revenue related to signed multi-year arrangements for hosted and installed subscription-based products. As of September 30, 2022, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $3.1 billion. The Company expects to recognize into revenue approximately 60% of this balance within one year, approximately 30% of this balance between one to two years and the remaining amount thereafter.

Inflation reduction act impact on ETR			In August 2022, the U.S. Congress passed the Inflation Reduction Act, which included a corporate minimum tax on book earnings of 15%, an excise tax on corporate share repurchases of 1%, and certain climate change and energy tax credit incentives. The adoption of a corporate minimum tax of 15% is not expected to impact Moody’s ETR. The excise tax of 1% on corporate share buybacks will not have an impact on the Company’s ETR for the years 2022 or 2023.
