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: MA and MIS. 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. 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. 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 2022 annual report on Form 10-K filed with the SEC on February 15, 2023. 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 in 2023 In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform - Scope,” which clarified the scope and application of the original guidance, ASU No. 2020-04, "Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU No. 2020-04"), issued in March 2020 (codified into ASC Topic 848 "Reference Rate Reform"). ASU No. 2020-04 provides temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. In December 2022, the FASB issued ASU 2022-06, "Reference Rate Reform—Deferral of the Sunset Date of Topic 848," which deferred the sunset date of Topic 848 to December 31, 2024. These ASU's were effective upon issuance and the amendments may be applied prospectively through December 31, 2024 as the transition from LIBOR is completed. During the first quarter of 2023, the Company modified the contractual terms of certain of its interest rate swaps designated as fair value hedges and cross-currency swaps designated as net investment hedges. These modifications replaced the previous LIBOR/EURIBOR-based reference rates included in the swap agreements to SOFR/ESTR-based rates. Pursuant to the modification of the contractual terms of these instruments, the Company utilized the optional expedients set forth in ASC Topic 848 relating to derivative instruments used in hedging relationships. The aggregate notional amounts of these swaps is disclosed in Note 8.

The following table presents the timing of revenue recognition: Three Months Ended March 31, 2023 Three Months Ended March 31, 2022 MA MIS Total MA MIS Total Revenue recognized at a point in time $ 27 $ 431 $ 458 $ 41 $ 529 $ 570 Revenue recognized over time 710 302 1,012 654 298 952 Total $ 737 $ 733 $ 1,470 $ 695 $ 827 $ 1,522 Unbilled receivables, deferred revenue and remaining performance obligations Unbilled receivables 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. In addition, certain MIS arrangements contain contractual terms whereby the customers are billed in arrears for annual monitoring services, requiring revenue to be accrued as an unbilled receivable as such services are provided. The following table presents the Company's unbilled receivables, which are included within accounts receivable, net, at March 31, 2023 and December 31, 2022: As of March 31, 2023 As of December 31, 2022 MA MIS MA MIS Unbilled Receivables $ 114 $ 439 $ 148 $ 385 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 months ended March 31, 2023 and 2022 are as follows: Three Months Ended March 31, 2023 Three Months Ended March 31, 2022 MA MIS Total MA MIS Total Balance at December 31, $ 1,055 $ 278 $ 1,333 $ 1,039 $ 296 $ 1,335 Changes in deferred revenue Revenue recognized that was included in the deferred revenue balance at the beginning of the period (471) (98) (569) (431) (95) (526) Increases due to amounts billable excluding amounts recognized as revenue during the period 688 179 867 636 178 814 Increases due to acquisitions during the period — — — 1 — 1 Effect of exchange rate changes 16 1 17 (11) (2) (13) Total changes in deferred revenue 233 82 315 195 81 276 Balance at March 31, $ 1,288 $ 360 $ 1,648 $ 1,234 $ 377 $ 1,611 Deferred revenue - current $ 1,287 $ 291 $ 1,578 $ 1,231 $ 294 $ 1,525 Deferred revenue - non-current $ 1 $ 69 $ 70 $ 3 $ 83 $ 86 The increase in deferred revenue during both the three months ended March 31, 2023 and 2022 is primarily due to the significant portion of contract renewals that occur during the first quarter within both segments.

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 March 31, 2023 2022 Stock-based compensation cost $ 47 $ 46 Tax benefit $ 10 $ 11 During the first three months of 2023, the Company granted 0.1 million employee stock options, which had a weighted average grant date fair value of $94.67 per share. The Company also granted 0.6 million shares of restricted stock in the first three months of 2023, which had a weighted average grant date fair value of $295.53 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 $286.04 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 2023: Expected dividend yield 1.04 % Expected stock volatility 29 % Risk-free interest rate 4.18 % Expected holding period 5.8 years Unrecognized stock-based compensation expense at March 31, 2023 was $20 million and $354 million for stock options and unvested restricted stock, respectively, which is expected to be recognized over a weighted average period of 2.2 years and 2.8 years, respectively. Additionally, there was $43 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 2.4 years. The following table summarizes information relating to stock option exercises and restricted stock vesting: Three Months Ended 2023 2022 Exercise of stock options: Proceeds from stock option exercises $ 7 $ 3 Aggregate intrinsic value $ 15 $ 4 Tax benefit realized upon exercise $ 4 $ 1 Number of shares exercised (1) 0.1 — Vesting of restricted stock: Fair value of shares vested $ 140 $ 166 Tax benefit realized upon vesting $ 33 $ 39 Number of shares vested 0.5 0.5 Vesting of performance-based restricted stock: Fair value of shares vested $ 24 $ 50 Tax benefit realized upon vesting $ 3 $ 7 Number of shares vested 0.1 0.2

INCOME TAXES

INCOME TAXES	3 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Moody’s effective tax rate (ETR) was 1.0% and 18.2% for the three months ended March 31, 2023 and 2022, respectively. The 17.2% decrease in the ETR for the three months ended March 31, 2023 compared to the same period in the prior year was primarily due to tax benefits recognized in the first quarter of 2023, which reflect the resolutions of uncertain tax positions in various U.S. and non-U.S. tax jurisdictions. The Company’s first quarter 2023 provision for income taxes 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 2023: i) net reductions in UTPs of $117 million related to the resolutions of UTPs; and ii) excess tax benefits from stock-based compensation of $6 million. 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 income (expense), net. 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 2019 through 2020 are currently under examination and 2021 remains open to examination. The Company’s New York City tax returns for 2015 through 2019 are currently under examination. The Company’s U.K. tax returns for 2017 through 2021 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 ASC Topic 740 regarding UTPs. The following table shows the amount the Company paid for income taxes: Three Months Ended March 31, 2023 2022 Income taxes paid $ 66 $ 70 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 2023.

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 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.

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”). T he Company estimates that the program will result in annualized savings of $120 million to $140 million per year. This program relates to the Company's post-COVID-19 geolocation strategy and includes the rationalization and exit of certain leased office spaces and a reduction in staff, including the relocation of certain job functions. The exit from certain leased office spaces began in the fourth quarter of 2022 and is expected to result in $50 million to $70 million of pre-tax charges from vacating the affected office spaces, a large portion of which Moody's intends to sublease. The program also includes $105 million to $120 million of pre-tax personnel-related restructuring charges, an amount that includes severance costs, expense related to the modification of equity awards, 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, which primarily relate to personnel-related costs, are expected to be $105 million to $120 million, which are expected to be paid through 2024. Substantially all of the $14 million in restructuring charges recognized during the quarter ended March 31, 2023 relate to employee termination costs. Changes to the restructuring liability for the aforementioned restructuring programs during the first three months of 2023 were as follows: Balance as of December 31, 2022 $ 65 2022 - 2023 Geolocation Restructuring Program: Cost incurred and adjustments $ 14 Cash payments and adjustments $ (42) Balance as of March 31, 2023 $ 37 Cumulative expense incurred through March 31, 2023 Employee Real Estate Related Other Costs Total 2022 - 2023 Geolocation Restructuring Program $ 98 $ 28 $ 1 $ 127

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	3 Months Ended

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company is organized into two operating segments: MA and MIS and accordingly, the Company reports in two reportable segments: MA and MIS. 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. 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 professional services. 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. Additionally, 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. 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.

Adoption of New Accounting Standards in 2023	Adoption of New Accounting Standards in 2023In January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform - Scope,” which clarified the scope and application of the original guidance, ASU No. 2020-04, "Facilitation of the Effects of Reference Rate Reform on Financial Reporting" ("ASU No. 2020-04"), issued in March 2020 (codified into ASC Topic 848 "Reference Rate Reform"). ASU No. 2020-04 provides temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens related to the expected market transition from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. In December 2022, the FASB issued ASU 2022-06, "Reference Rate Reform—Deferral of the Sunset Date of Topic 848," which deferred the sunset date of Topic 848 to December 31, 2024. These ASU's were effective upon issuance and the amendments may be applied prospectively through December 31, 2024 as the transition from LIBOR is completed.

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 2023.
