DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION	12 Months Ended

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. Certain reclassifications have been made to prior period amounts to conform to the current presentation. Adoption of New Accounting Standards in 2022 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 Company may elect to apply the amendments prospectively through December 31, 2024 as the transition from LIBOR is completed. As of December 31, 2022, the Company has interest rate swaps designated as fair value hedges and cross currency swaps designated as net investment hedges referencing three-month or six-month USD LIBOR with aggregate notional amounts as disclosed in Note 7. For derivative instruments that will be outstanding at the transition date, the Company intends to modify the contractual terms of the instruments to replace LIBOR with another reference rate, such as SOFR. Pursuant to the modification of the contractual terms of these instruments, the Company intends to utilize the various optional expedients set forth in ASC Topic 848 relating to derivative instruments used in hedging relationships. 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. 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 3.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Consolidation The consolidated financial statements include those of Moody’s Corporation and its majority- and wholly-owned subsidiaries. The effects of all intercompany transactions have been eliminated. Investments in companies for which the Company has significant influence over operating and financial policies but not a controlling interest are accounted for on an equity basis whereby the Company records its proportional share of the investment’s net income or loss as part of other non-operating income (expense), net and any dividends received reduce the carrying amount of the investment. Equity investments without a readily determinable fair value for which the Company does not have significant influence are accounted for under the ASC 321 measurement alternative; these investments are recorded at initial cost, less impairment, adjusted upward or downward for any observable price changes in similar investments. The Company applies the guidelines set forth in Topic 810 of the ASC in assessing its interests in variable interest entities to decide whether to consolidate an entity. The Company has reviewed the potential variable interest entities and determined that there are no consolidation requirements under Topic 810 of the ASC. The Company consolidates its ICRA subsidiaries on a three month lag. Cash and Cash Equivalents Cash equivalents principally consist of investments in money market deposit accounts as well as certificates of deposit with maturities of three months or less when purchased. Short-term Investments Short-term investments are securities with maturities greater than 90 days at the time of purchase that are available for operations in the next 12 months. The Company’s short-term investments primarily consist of certificates of deposit and their cost approximates fair value due to the short-term nature of the instruments. Interest and dividends on these investments are recorded into income when earned. Property and Equipment Property and equipment are stated at cost and are depreciated using the straight-line method over their estimated useful lives. Expenditures for maintenance and repairs that do not extend the economic useful life of the related assets are charged to expense as incurred. Computer Software Developed or Obtained for Internal Use The Company capitalizes costs related to software developed or obtained for internal use. These assets, included in property and equipment in the consolidated balance sheets, relate to the Company’s financial, website and other systems. Such costs generally consist of direct costs for third-party license fees, professional services provided by third parties and employee compensation, in each case incurred either during the application development stage or in connection with upgrades and enhancements that increase functionality. Such costs are depreciated over their estimated useful lives on a straight-line basis. Costs incurred during the preliminary project stage of development as well as maintenance costs are expensed as incurred. The Company also capitalizes implementation costs incurred in cloud computing arrangements (e.g., hosted arrangements) and depreciates the costs over the non-cancellable term of the cloud computing arrangements plus any option renewal periods that are reasonably certain to be exercised or for which the exercise is controlled by the service provider. The Company classifies the amortization of capitalized implementation costs in the same line item in the statement of operations as the fees associated with the hosting service (i.e., operating and SG&A expense) and classifies the related payments in the statement of cash flows in the same manner as payments made for fees associated with the hosting service (i.e. cash flows from operating activities). In addition, the capitalization of implementation costs is reflected in the balance sheet consistent with the location of prepayment of fees for the hosting element (i.e., within other current assets or other assets). Goodwill and Other Acquired Intangible Assets Moody’s evaluates its goodwill for impairment at the reporting unit level, defined as an operating segment (i.e., MIS and MA), or one level below an operating segment (i.e., a component of an operating segment), annually as of July 31 or more frequently if impairment indicators arise in accordance with ASC Topic 350. The Company evaluates the recoverability of goodwill using a two-step impairment test approach at the reporting unit level. In the first step, the Company assesses various qualitative factors to determine whether the fair value of a reporting unit may be less than its carrying amount. If a determination is made based on the qualitative factors that an impairment does not exist, the Company is not required to perform further testing. If the aforementioned qualitative assessment results in the Company concluding that it is more likely than not that the fair value of a reporting unit may be less than its carrying amount, the fair value of the reporting unit will be quantitatively determined and compared to its carrying value including goodwill. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and the Company is not required to perform further testing. If the fair value of the reporting unit is less than the carrying value, the Company will record a goodwill impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value. The Company evaluates its reporting units on an annual basis, or more frequently if there are changes in the reporting structure of the Company due to acquisitions, reporting unit realignments or if there are indicators of potential impairment. For the reporting units where the Company is consistently able to conclude that no impairment exists using only a qualitative approach, the Company’s accounting policy is to perform the second step of the aforementioned goodwill impairment assessment at least once every three years. Goodwill is assigned to a reporting unit at the date when an acquisition is integrated into one of the established reporting units, and is based on which reporting unit is expected to benefit from the synergies of the acquisition. For purposes of assessing the recoverability of goodwill, the Company has four reporting units: two within the Company’s ratings business (one for the ICRA business and one that encompasses all of Moody’s other ratings operations) and two reporting units within MA consisting of businesses that offer: i) data and data-driven analytical solutions; and ii) risk-management software, workflow and CRE solutions. Impairment of long-lived assets and definite-lived intangible assets Long-lived assets (including ROU Assets) and amortizable intangible assets are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Under the first step of the recoverability assessment, the Company compares the estimated undiscounted future cash flows attributable to the asset or asset group to their carrying value. If the undiscounted future cash flows are greater than the carrying value, no further assessment is required. If the undiscounted future cash flows are less than the carrying value, Moody's proceeds with step two of the assessment. Under step two of this assessment, Moody's is required to determine the fair value of the asset or asset group (reduced by the estimated cost to sell the asset for assets or disposal groups classified as held-for-sale) and recognize an impairment loss if the carrying amount exceeds its fair value. Stock-Based Compensation The Company records compensation expense over the requisite service period for all share-based payment award transactions granted to employees based on the fair value of the equity instrument at the time of grant. This includes shares issued under stock option and restricted stock plans. Derivative Instruments and Hedging Activities Based on the Company’s risk management policy, the Company may use derivative financial instruments to reduce exposure to changes in foreign exchange rates and interest rates. The Company does not enter into derivative financial instruments for speculative purposes. All derivative financial instruments are recorded on the balance sheet at their respective fair values on a gross basis. The changes in the value of derivatives that qualify as fair value hedges are recorded in the same income statement line item in earnings in which the corresponding adjustment to the carrying value of the hedged item is presented. The entire change in the fair value of derivatives that qualify as cash flow hedges is recorded to OCI and such amounts are reclassified from AOCI(L) to the same income statement line in earnings in the same period or periods during which the hedged transaction affects income. The Company assesses effectiveness for net investment hedges using the spot-method. The entire change in the fair value of derivatives that qualify as net investment hedges is initially recorded to OCI. Those changes in fair value attributable to components included in the assessment of hedge effectiveness in a net investment hedge are recorded in the currency translation adjustment component of OCI and remain in AOCI(L) until the period in which the hedged item affects earnings. Those changes in fair value attributable to components excluded from the assessment of hedge effectiveness in a net investment hedge are recorded to OCI and amortized to earnings using a systematic and rational method over the duration of the hedge. Any changes in the fair value of derivatives that the Company does not designate as hedging instruments under Topic 815 of the ASC are recorded in the consolidated statements of operations in the period in which they occur. Revenue Recognition and Costs to Obtain or Fulfill a Contract with a Customer Revenue recognition: Revenue is recognized when control of promised goods or services is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. When contracts with customers contain multiple performance obligations, the Company accounts for individual performance obligations separately if they are distinct. The transaction price is allocated to each distinct performance obligation on a relative SSP basis. The Company determines the SSP by using the price charged for a deliverable when sold separately or uses management’s best estimate of SSP for goods or services not sold separately using estimation techniques that maximize observable data points, including: internal factors relevant to its pricing practices such as costs and margin objectives; standalone sales prices of similar products; pricing policies; percentage of the fee charged for a primary product or service relative to a related product or service; and customer segment and geography. Additional consideration is also given to market conditions such as competitor pricing strategies and market trends. Sales, usage-based, value added and other taxes are excluded from revenues. MIS Revenue In the MIS segment, revenue arrangements with multiple elements are generally comprised of two distinct performance obligations, a rating and the related monitoring service. Revenue attributed to ratings of issued securities is generally recognized when the rating is delivered to the issuer. Revenue attributed to monitoring of issuers or issued securities is recognized ratably over the period in which the monitoring is performed, generally one year. In the case of certain structured finance products, primarily CMBS, issuers can elect to pay all of the annual monitoring fees upfront. These fees are deferred and recognized over the future monitoring periods based on the expected lives of the rated securities. MIS arrangements generally have standard contractual terms for which the stated payments are due at conclusion of the ratings process for ratings and either upfront or in arrears for monitoring services; and are signed by customers either on a per issue basis or at the beginning of the relationship with the customer. In situations when customer fees for an arrangement may be variable, the Company estimates the variable consideration at inception using the expected value method based on analysis of similar contracts in the same line of business, which is constrained based on the Company’s assessment of the realization of the adjustment amount. The Company allocates the transaction price within arrangements that include multiple performance obligations based upon the relative SSP of each service. The SSP for both rating and monitoring services is generally based upon observable selling prices where the rating or monitoring service is sold separately to similar customers. MA Revenue In the MA segment, products and services offered by the Company include hosted research and data subscriptions, installed and hosted software subscriptions, perpetual installed software licenses and related maintenance, or PCS, and professional services. Subscription and PCS contracts are generally invoiced in advance of the contractual coverage period, which is principally one year, but can range from 3-5 years. Perpetual software licenses are generally invoiced upon delivery and professional services are invoiced as those services are provided. Payment terms and conditions vary by contract type, but primarily include a requirement of payment within 30 to 60 days. Revenue from research, data and other hosted subscriptions is recognized ratably over the related subscription period as MA's performance obligation to provide access to these products is progressively fulfilled over the stated term of the contract. A large portion of these services are invoiced in the months of November, December and January. Revenue from the sale of a software license, when considered distinct from the related software implementation services, is generally recognized at the time the product master or first copy is delivered or transferred to the customer. PCS is generally recognized ratably over the contractual period commencing when the software license is fully delivered. Revenue from installed software subscriptions, which includes PCS, is bifurcated into a software license performance obligation and a PCS performance obligation, which follow the patterns of recognition described above. For implementation services and other service projects for which fees are fixed, the Company determined progress towards completion is most accurately measured on a percentage-of-completion basis (input method) as this approach utilizes the most directly observable data points and is therefore used to recognize the related revenue. For implementation services where price varies based on time expended, a time-based measure of progress towards completion of the performance obligation is utilized. Revenue from professional services rendered is generally recognized over time as the services are performed. Products and services offered within the MA segment are sold either stand-alone or together in various combinations. In instances where an arrangement contains multiple performance obligations, the Company accounts for the individual performance obligations separately if they are considered distinct. Revenue is generally allocated to all performance obligations based upon the relative SSP at contract inception. For certain performance obligations, judgment is required to determine the SSP. Revenue is recognized for each performance obligation based upon the conditions for revenue recognition noted above. In the MA segment, customers usually pay a fixed fee for the products and services based on signed contracts. However, accounting for variable consideration is applied mainly for: i) estimates for cancellation rights and price concessions and ii) T&M based services. The Company estimates the variable consideration associated with cancellation rights and price concessions based on the expected amount to be provided to customers and reduces the amount of revenue to be recognized. Costs to Obtain or Fulfill a Contract with a Customer: Costs to obtain a contract with a customer Costs incurred to obtain customer contracts, such as sales commissions, are deferred and recorded within other current assets and other assets when such costs are determined to be incremental to obtaining a contract, would not have been incurred otherwise and the Company expects to recover those costs. These costs are amortized to expense on a systematic basis consistent with the transfer of the products or services to the customer. Depending on the line of business to which the contract relates, this may be based upon the average economic life of the products sold or average period for which services are provided, inclusive of anticipated contract renewals. Determining the estimated economic life of the products sold requires judgment with respect to anticipated future technological changes. Costs to obtain customer contracts are only incurred in the MA segment. Cost to fulfill a contract with a customer Costs incurred to fulfill customer contracts, are deferred and recorded within other current assets and other assets when such costs relate directly to a contract, generate or enhance resources of the Company that will be used in satisfying performance obligations in the future and the Company expects to recover those costs. The Company capitalizes work-in-process costs for in-progress MIS ratings, which is recognized consistent with the rendering of the related services to the customers, as ratings are issued. In addition, within the MA segment, the Company capitalizes royalty costs related to third-party information data providers associated with hosted company information and business intelligence products. These costs are amortized to expense consistent with the recognition pattern of the related revenue over time. Accounts Receivable Allowances In order to determine an estimate of expected credit losses, receivables are segmented based on similar risk characteristics including historical credit loss patterns and industry or class of customers to calculate reserve rates. The Company uses an aging method for developing its allowance for credit losses by which receivable balances are stratified based on aging category. A reserve rate is calculated for each aging category which is generally based on historical information, and is adjusted, when necessary, for current conditions (e.g., macroeconomic or industry related) and reasonable and supportable forecasts about the future. The Company also considers customer specific information (e.g., bankruptcy or financial difficulty) when estimating its expected credit losses, as well as the economic environment of the customers, both from an industry and geographic perspective, in evaluating the need for allowances. Expected credit losses are reflected as additions to the accounts receivable allowance. Actual uncollectible account write-offs are recorded against the allowance. Leases The Company has operating leases, which substantially all relate to the lease of office space. The Company’s leases which are classified as finance leases are not material to the consolidated financial statements. The Company determines if an arrangement meets the definition of a lease at contract inception. The Company recognizes in its consolidated balance sheet a lease liability and an ROU Asset for all leases with a lease term greater than 12 months. In determining the length of the lease term, the Company utilizes judgment in assessing the likelihood of whether it is reasonably certain that it will exercise an option to extend or early-terminate a lease, if such options are provided in the lease agreement. ROU Assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU Assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As substantially all of the Company’s leases do not provide an implicit interest rate, the Company uses its estimated secured incremental borrowing rates at the lease commencement date in determining the present value of lease payments. These secured incremental borrowing rates are attributable to the currency in which the lease is denominated. At commencement, the Company’s initial measurement of the ROU Asset is calculated as the present value of the remaining lease payments (i.e., lease liability), with additive adjustments reflecting: initial direct costs (e.g., broker commissions) and prepaid lease payments (if any); and reduced by any lease incentives provided by the lessor if: (i) received before lease commencement or (ii) receipt of the lease incentive is contingent upon future events for which the occurrence is both probable and within the Company’s control. Lease expense for minimum operating lease payments is recognized on a straight-line basis over the lease term. This straight-line lease expense represents a single lease cost which is comprised of both an interest accretion component relating to the lease liability and amortization of the ROU Assets. The Company records this single lease cost in operating and SG&A expenses. However, in situations where an operating lease ROU Asset has been impaired, the subsequent amortization of the ROU Asset is then recorded on a straight-line basis over the remaining lease term and is combined with accretion expense on the lease liability to result in single operating lease cost (which subsequent to impairment will no longer follow a straight-line recognition pattern). The Company has lease agreements which include lease and non-lease components. For the Company’s office space leases, the lease components (e.g., fixed rent payments) and non-lease components (e.g., fixed common-area maintenance costs) are combined and accounted for as a single lease component. Variable lease payments (e.g. variable common-area-maintenance costs) are only included in the initial measurement of the lease liability to the extent those payments depend on an index or a rate. Variable lease payments not included in the lease liability are recognized in net income in the period in which the obligation for those payments is incurred. Contingencies Moody’s is involved in legal and tax proceedings, governmental, regulatory and legislative investigations and inquiries, claims and litigation that are incidental to the Company’s business, including claims based on ratings assigned by MIS. Moody’s is also subject to ongoing tax audits in the normal course of business. Management periodically assesses the Company’s liabilities and contingencies in connection with these matters based upon the latest information available. Moody’s discloses material pending legal proceedings pursuant to SEC rules and other pending matters as it may determine to be appropriate. 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. In view of the inherent difficulty of assessing the potential outcome of legal proceedings, governmental, regulatory and legislative investigations and inquiries, claims and litigation and similar matters and contingencies, particularly when the claimants seek large or indeterminate damages or assert novel legal theories or the matters involve a large number of parties, the Company often cannot predict what the eventual outcome of the pending matters will be or the timing of any resolution of such matters. The Company also may be unable to predict the impact (if any) that any such matters may have on how its business is conducted, on its competitive position or on its financial position, results of operations or cash flows. As the process to resolve any pending matters progresses, management will continue to review the latest information available and assess its ability to predict the outcome of such matters and the effects, if any, on its operations and financial condition and to accrue for and disclose such matters as and when required. However, because such matters are inherently unpredictable and unfavorable developments or resolutions can occur, the ultimate outcome of such matters, including the amount of any loss, may differ from those estimates. Operating Expenses Operating expenses include costs associated with the development and production of the Company’s products and services and their delivery to customers. These expenses principally include employee compensation and benefits and travel costs that are incurred in connection with these activities. Operating expenses are charged to income as incurred. Selling, General and Administrative Expenses SG&A expenses include such items as compensation and benefits for corporate officers and staff and compensation and other expenses related to sales. They also include items such as office rent, business insurance and professional fees. SG&A expenses are charged to income as incurred. Foreign Currency Translation For all operations outside the U.S. where the Company has designated the local currency as the functional currency, assets and liabilities are translated into U.S. dollars using end of year exchange rates, and revenue and expenses are translated using average exchange rates for the year. For these foreign operations, currency translation adjustments are recorded to other comprehensive income. Comprehensive Income Comprehensive income represents the change in net assets of a business enterprise during a period due to transactions and other events and circumstances from non-owner sources including: foreign currency translation impacts; net actuarial gains and losses and net prior service costs related to pension and other retirement plans; and gains and losses on derivative instruments designated as net investment hedges or cash flow hedges. Comprehensive income items, including cumulative translation adjustments of entities that are less-than-wholly-owned subsidiaries, will be reclassified to noncontrolling interests and thereby, adjusting accumulated other comprehensive income proportionately in accordance with the percentage of ownership interest of the non-controlling shareholder. Income Taxes The Company accounts for income taxes under the asset and liability method in accordance with ASC Topic 740. Therefore, income tax expense is based on reported income before income taxes and deferred income taxes reflect the effect of temporary differences between the amounts of assets and liabilities that are recognized for financial reporting purposes and the amounts that are recognized for income tax purposes. The Company classifies interest related to unrecognized tax benefits as a component of interest expense in its consolidated statements of operations. Penalties are recognized in other non-operating expenses. For UTPs, the Company first determines whether it is more-likely-than-not (defined as a likelihood of more than fifty percent) that a tax position will be sustained based on its technical merits as of the reporting date, assuming that taxing authorities will examine the position and have full knowledge of all relevant information. A tax position that meets this more-likely-than-not threshold is then measured and recognized at the largest amount of benefit that is greater than fifty percent likely to be realized upon effective settlement with a taxing authority. On December 22, 2017, the Tax Act was signed into law, resulting in all previously undistributed foreign earnings being subject to U.S. tax. The Company has provided deferred taxes for those entities whose earnings are not considered indefinitely reinvested. Fair Value of Financial Instruments The Company’s financial instruments include cash, cash equivalents, trade receivables and payables, and certain short-term investments consisting primarily of certificates of deposit and money market deposits, all of which are short-term in nature and, accordingly, approximate fair value. The Company also invests in mutual funds, which are accounted for as equity securities with readily determinable fair values under ASC Topic 321. The Company measures these investments at fair value with both realized gains and losses and unrealized holding gains and losses for these investments included in net income. Also, the Company uses derivative instruments to manage certain financial exposures that occur in the normal course of business. These derivative instruments are carried at fair value in the Company’s consolidated balance sheets. Fair value is defined by the ASC 820 as the price that would be received from selling an asset or paid to transfer a liability (i.e., an exit price) in an orderly transaction between market participants at the measurement date. The determination of this fair value is based on the principal or most advantageous market in which the Company could commence transactions and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions and risk of nonperformance. Also, determination of fair value assumes that market participants will consider the highest and best use of the asset. The ASC establishes a fair value hierarchy whereby the inputs contained in valuation techniques used to measure fair value are categorized into three broad levels as follows: Level 1: quoted market prices in active markets that the reporting entity has the ability to access at the date of the fair value measurement; Level 2: inputs other than quoted market prices described in Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value measurement of the assets or liabilities. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk principally consist of cash and cash equivalents, short-term investments, trade receivables and derivatives. For cash and cash equivalents, short-term investments and derivatives, the Company manages its credit exposure by limiting the amount of counterparty risk with any particular financial institution; limits are assigned to each counterparty based on perceived quality of credit, and are monitored daily. Cash equivalents are held among various money market deposit accounts and certificates of deposits as of December 31, 2022 and 2021. Short-term investments primarily consist of certificates of deposit as of December 31, 2022 and 2021. Derivatives primarily consist of foreign exchange forwards or swap contracts (interest rate swaps and cross-currency swaps) as of December 31, 2022 and 2021. For trade receivables, no customer accounted for 10% or more of accounts receivable at December 31, 2022 or 2021. Earnings per Share of Common Stock Basic shares outstanding is calculated based on the weighted average number of shares of common stock outstanding during the reporting period. Diluted shares outstanding is calculated giving effect to

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.

Certain MIS arrangements contain contractual terms whereby the customers are billed in arrears for annual monitoring services and rating fees, requiring revenue to be accrued as an unbilled receivable as such services are provided. 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. Accordingly, at December 31, 2022 and December 31, 2021, accounts receivable included approximately $148 million and $152 million, respectively, of unbilled receivables related to the MA segment. Deferred revenue The Company recognizes deferred revenue when a contract requires a customer to pay consideration to the Company in advance of when revenue 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 year ended December 31, 2022 are as follows: Year Ended December 31, 2022 MIS MA Total Balance at December 31, 2021 $ 296 $ 1,039 $ 1,335 Changes in deferred revenue Revenue recognized that was included in the deferred revenue balance at the beginning of the period (210) (996) (1,206) Increases due to amounts billable excluding amounts recognized as revenue during the period 202 1,018 1,220 Increases due to acquisitions during the period — 1 1 Effect of exchange rate changes (10) (7) (17) Total changes in deferred revenue (18) 16 (2) Balance at December 31, 2022 $ 278 $ 1,055 $ 1,333 Deferred revenue - current $ 205 $ 1,053 $ 1,258 Deferred revenue - noncurrent $ 73 $ 2 $ 75 Significant changes in the deferred revenue balances during the year ended December 31, 2021 are as follows: Year Ended December 31, 2021 MIS MA Total Balance at December 31, 2020 $ 313 $ 874 $ 1,187 Changes in deferred revenue Revenue recognized that was included in the deferred revenue balance at the beginning of the period (220) (810) (1,030) Increases due to amounts billable excluding amounts recognized as revenue during the period 207 884 1,091 Increases due to acquisitions during the period — 94 94 Effect of exchange rate changes (4) (3) (7) Total changes in deferred revenue (17) 165 148 Balance at December 31, 2021 $ 296 $ 1,039 $ 1,335 Deferred revenue—current $ 214 $ 1,035 $ 1,249 Deferred revenue—noncurrent $ 82 $ 4 $ 86 For the MA segment, for the year ended December 31, 2021, the increase in the deferred revenue balance was primarily due to acquisitions (Cortera, RMS, and PassFort) and organic growth. Significant changes in the deferred revenue balances during the year ended December 31, 2020 are as follows: Year Ended December 31, 2020 MIS MA Total Balance at December 31, 2019 $ 322 $ 840 $ 1,162 Changes in deferred revenue Revenue recognized that was included in the deferred revenue balance at the beginning of the period (229) (800) (1,029) Increases due to amounts billable excluding amounts recognized as revenue during the period 215 792 1,007 Increases due to acquisitions during the period — 24 24 Effect of exchange rate changes 5 18 23 Total changes in deferred revenue (9) 34 25 Balance at December 31, 2020 $ 313 $ 874 $ 1,187 Deferred revenue—current $ 216 $ 873 $ 1,089 Deferred revenue—noncurrent $ 97 $ 1 $ 98 For the MA segment, for the year ended December 31, 2020, the increase in the deferred revenue balance was primarily due to acquisitions (RDC, Acquire Media, ZMFS, and Catylist) and changes in FX translation rates. 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 December 31, 2022, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $99 million. The Company expects to recognize into revenue approximately 25% 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 of unsatisfied performance obligations relating to 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 December 31, 2022 as well as amounts not yet invoiced to customers as of December 31, 2022 largely reflecting future revenue related to signed multi-year arrangements for hosted and installed subscription-based products. As of December 31, 2022, the aggregate amount of the transaction price allocated to remaining performance obligations was approximately $3.5 billion. The Company expects to recognize into revenue approximately 60% of this balance within one year, approximately 25% of this balance between one to two years and the remaining amount thereafter.

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: Nature of Swap Notional Amount Floating Interest Rate Hedged Item 2022 2021 2017 Senior Notes due 2023 Pay Floating/Receive Fixed $ — $ 250 3-month LIBOR 2017 Senior Notes due 2028 Pay Floating/Receive Fixed $ 500 $ 500 3-month LIBOR 2020 Senior Notes due 2025 Pay Floating/Receive Fixed $ 300 $ 300 6-month LIBOR 2014 Senior Notes due 2044 Pay Floating/Receive Fixed $ 300 $ 300 3-month LIBOR 2018 Senior Notes due 2048 Pay Floating/Receive Fixed $ 300 $ 300 3-month LIBOR 2018 Senior Notes due 2029 (1) Pay Floating/Receive Fixed $ 400 $ — SOFR 2022 Senior Notes due 2052 (1) Pay Floating/Receive Fixed $ 500 $ — SOFR 2022 Senior Notes due 2032 (1) Pay Floating/Receive Fixed $ 250 $ — SOFR Total Total $ 2,550 $ 1,650 (1) Executed in 2022.

These hedges are designated as accounting hedges under the applicable sections of ASC Topic 815 and will end upon the repayment of the notes in 2027 and 2030, respectively, unless terminated early at the discretion of the Company. Cross currency swaps designated as net investment hedges The Company enters into cross-currency swaps to mitigate FX exposure related to a portion of the Company’s euro net investment in certain foreign subsidiaries against changes in euro/USD exchange rates.

These forward contracts are not designated as accounting hedges under the applicable sections of Topic 815 of the ASC. Accordingly, changes in the fair value of these contracts are recognized immediately in other non-operating income, net in the Company’s consolidated statements of operations along with the FX gain or loss recognized on the assets and liabilities denominated in a currency other than the subsidiary’s functional currency. These contracts have expiration dates at various times through April 2023.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS	ACQUISITIONS The following is a discussion of material acquisitions completed by the Company. The business combinations described below are accounted for using the acquisition method of accounting whereby assets acquired and liabilities assumed were recognized at fair value 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. With the exception of RMS, the Company has not presented pro forma combined results for these acquisitions because the impact on previously reported statements of operations would not have been material. PassFort On November 30, 2021, the Company acquired 100% of PassFort, a U.K. SaaS-based workflow platform for identity verification, customer onboarding, and risk analysis. The table below details the total consideration relating to the acquisition: Cash paid at closing $ 157 Additional consideration paid to sellers in 2022 (1) 1 Total consideration $ 158 (1) Represents additional consideration paid to the sellers following finalization of customary post-closing completion adjustments. Shown below is the purchase price allocation, which summarizes the fair value of the assets and liabilities assumed, at the date of acquisition: Cash $ 10 Accounts receivable 1 Intangible assets: Product technology (5 year useful life) $ 14 Customer relationships (16 year useful life) 8 Trade name (4 year useful life) 1 Total intangible assets (9 year weighted average useful life) 23 Goodwill 138 Liabilities: Accounts payable and accrued liabilities $ (7) Deferred revenue (1) Deferred tax liabilities (6) Total liabilities (14) Net assets acquired $ 158 Goodwill The goodwill recognized as a result of this acquisition includes, among other things, value created by combining the complementary risk assessment products of the Company and PassFort. The integration of PassFort’s platform into Moody’s suite of KYC and compliance offerings is expected to create a holistic workflow solution to benefit both new and existing Moody's customers. Goodwill, which has been assigned to the MA segment, is not deductible for tax purposes. Transaction costs Transaction costs directly related to the PassFort acquisition were not material. 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 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 uncertain tax positions 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 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 twelve months ended December 31, 2021 and 2020 as if the acquisition of RMS occurred on January 1, 2020. The pro forma financial information is presented for comparative purposes only, 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. Year Ended December 31, Unaudited 2021 2020 Pro forma Revenue $ 6,463 $ 5,667 Pro forma Net Income attributable to Moody's $ 2,244 $ 1,666 The unaudited pro forma results do not include any anticipated cost savings or other effects of the planned integration of RMS. Accordingly, the pro forma results above are not necessarily indicative of the results that would have been reported if the acquisition had occurred on the dates indicated, nor are the pro forma results indicative of results which may occur in the future. The RMS results included in the above have been converted to U.S. GAAP from IFRS as issued by the IASB and have been translated to USD at rates in effect for the periods presented. The RMS amounts in the pro forma results include an addition to revenue of approximately $18 million and a reduction to revenue of approximately $22 million relating to a fair value adjustment to deferred revenue required as part of acquisition accounting for the years ended December 31, 2021 and 2020, respectively.

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. The 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 leased office spaces and a reduction in staff, including the relocation of certain job functions. The exit from certain leased office spaces began late in 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 $85 million to $100 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 are expected to be $85 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 related 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. On July 29, 2020, the chief executive officer of Moody’s approved a restructuring program (the “2020 Real Estate Rationalization Restructuring Program”) primarily in response to the COVID-19 pandemic which revolved around the rationalization and exit of certain leased office spaces. The exit from certain leased office space began in the third quarter of 2020 and was substantially completed at December 31, 2021. The 2020 Real Estate Rationalization Restructuring Program primarily reflected non-cash charges related to the impairment of operating lease right-of-use assets and leasehold improvements. The 2020 Restructuring Program is expected to result in an estimated annualized savings of approximately $5 million to $6 million a year. Total expenses included in the accompanying consolidated statements of operations relating to the Company's restructuring programs are as follows: Year Ended December 31, 2022 Employee Termination Costs (1) Real Estate Related Costs (2) Other Costs (3) Total 2020 Real Estate Rationalization Restructuring Program $ — $ 2 $ — $ 2 2020 MA Strategic Reorganization Restructuring Program (1) — — (1) 2022 - 2023 Geolocation Restructuring Program 85 27 1 113 Total Restructuring $ 84 $ 29 $ 1 $ 114 Year Ended December 31, 2021 Employee Termination Costs (1) Real Estate Related Costs Other Total 2018 Restructuring Program $ (2) $ — $ — $ (2) 2020 MA Strategic Reorganization Restructuring Program 2 — — 2 Total Restructuring $ — $ — $ — $ — Year Ended December 31, 2020 Employee Termination Costs (1) Real Estate Related Costs (4) Other Total 2018 Restructuring Program $ (4) $ — $ — $ (4) 2020 Real Estate Rationalization Restructuring Program — 36 — 36 2020 MA Strategic Reorganization Restructuring Program 18 — — 18 Total Restructuring $ 14 $ 36 $ — $ 50 (1) Includes severance costs and expense related to the modification of equity awards.

The following are descriptions of the methodologies utilized by the Company to estimate the fair value of its derivative contracts and 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.

Retirement Benefits [Abstract]
PENSION AND OTHER RETIREMENT BENEFITS	PENSION AND OTHER RETIREMENT BENEFITS U.S. Plans Moody’s maintains funded and unfunded noncontributory Defined Benefit Pension Plans ("DBPPs"). The DBPPs provide defined benefits using a cash balance formula based on years of service and career average salary or final average pay for selected executives. The Company also provides certain healthcare and life insurance benefits for retired U.S. employees. The retirement healthcare plans are contributory; the life insurance plans are noncontributory. Moody’s funded and unfunded U.S. pension plans, the U.S. retirement healthcare plans and the U.S. retirement life insurance plans are collectively referred to herein as the “Retirement Plans.” The U.S. retirement healthcare plans and the U.S. retirement life insurance plans are collectively referred to herein as the “Other Retirement Plans.” Through 2007, substantially all U.S. employees were eligible to participate in the Company’s DBPPs. Effective January 1, 2008, the Company no longer offers DBPPs to U.S. employees hired or rehired on or after January 1, 2008 and new hires in the U.S. instead will receive a retirement contribution in similar benefit value under the Company’s Profit Participation Plan. Current participants of the Company’s Retirement Plans and Other Retirement Plans continue to accrue benefits based on existing plan benefit formulas. Following is a summary of changes in benefit obligations and fair value of plan assets for the Retirement Plans for the years ended December 31: Pension Plans Other Retirement Plans 2022 2021 2022 2021 Change in benefit obligation: Benefit obligation, beginning of the period $ (570) $ (663) $ (48) $ (48) Service cost (14) (19) (4) (4) Interest cost (15) (14) (1) (1) Plan participants’ contributions — — (1) (1) Benefits paid 20 68 2 2 Actuarial (loss) gain 1 (6) — (3) Assumption changes 116 64 13 7 Benefit obligation, end of the period $ (462) $ (570) $ (39) $ (48) Change in plan assets: Fair value of plan assets, beginning of the period $ 544 $ 528 $ — $ — Actual return on plan assets (111) 34 — — Benefits paid (20) (68) (2) (2) Employer contributions 7 50 1 1 Plan participants’ contributions — — 1 1 Fair value of plan assets, end of the period $ 420 $ 544 $ — $ — Funded status of the plans $ (42) $ (26) $ (39) $ (48) Amounts recorded on the consolidated balance sheets: Pension and retirement benefits asset – non current $ 39 $ 74 $ — $ — Pension and retirement benefits liability – current (5) (5) (2) (1) Pension and retirement benefits liability – non current (76) (95) (37) (47) Net amount recognized $ (42) $ (26) $ (39) $ (48) Accumulated benefit obligation, end of the period $ (432) $ (524) The net decrease in the pension benefit obligation from assumption changes and actuarial gains in 2022 primarily resulted from increases to discount rates, partially offset by an increase to the annuity conversion rate. The net decrease in the pension benefit obligation from assumption changes and actuarial losses in 2021 primarily resulted from increases to the discount rates and changes to certain actuarial assumptions, including increased rates of retirement at younger ages.

As the assumption reflects a long-term time horizon, the plan performance in any one particular year does not, by itself, significantly influence the Company’s evaluation. For 2022, the expected rate of return used in calculating the net periodic benefit costs was 5.05%. For 2023, the Company’s expected rate of return assumption is 6.55% to reflect the Company’s current view of long-term capital market outlook. Plan Assets Moody’s investment objective for the assets in the funded pension plan is to earn total returns that will minimize future contribution requirements over the long-term within a prudent level of risk. The Company works with its independent investment consultants to determine asset allocation targets for its pension plan investment portfolio based on its assessment of business and financial conditions, demographic and actuarial data, funding characteristics, and related risk factors. Other relevant factors, including historical and forward looking views of inflation and capital market returns, are also considered. Risk management practices include monitoring plan asset performance, diversification across asset classes and investment styles and periodic rebalancing toward asset allocation targets. The Company’s Asset Management Committee is responsible for overseeing the investment activities of the plan, which includes selecting acceptable asset classes, defining allowable ranges of holdings by asset class and by individual investment managers, defining acceptable securities within each asset class, and establishing investment performance expectations. Ongoing monitoring of the plan includes reviews of investment performance and managers on a regular basis, annual liability measurements, and periodic asset/liability studies. The Company’s investment policy uses risk-controlled investment strategies by increasing the plan’s asset allocation to fixed income securities and specifying ranges of acceptable target allocation by asset class based on different levels of the plan’s accounting funded status. In addition, the investment policy also requires the investment-grade fixed income assets to be rebalanced between shorter and longer duration bonds as the interest rate environment changes. This investment policy is designed to help protect the plan’s funded status and to limit volatility of the Company’s contributions. Based on the policy, the Company’s current target asset allocation is approximately 33% (range of 28% to 38%) in equity securities, 62% (range of 57% to 67%) in fixed income securities and 5% (range of 2% to 8%) in other investments and the plan will use a combination of active and passive investment strategies and different investment styles for its investment portfolios within each asset class. The plan’s equity investments are diversified across U.S. and non-U.S. stocks of small, medium and large capitalization. The plan’s fixed income investments are diversified principally across U.S. and non-U.S. government and corporate bonds, which are expected to help reduce plan exposure to interest rate variation and to better align assets with obligations. The plan also invests in other fixed income investments such as debts rated below investment grade, emerging market debt, and convertible securities. The plan’s other investment, which is made through a private real estate debt fund, is expected to provide additional diversification benefits and absolute return enhancement to the plan assets. Fair value of the assets in the Company’s funded pension plan by asset category at December 31, 2022 and 2021 are as follows: Fair Value Measurement as of December 31, 2022 Asset Category Balance Level 1 Level 2 Measured using NAV practical expedient (1) % of total Cash and cash equivalent $ 5 $ — $ 5 $ — 1 % Common/collective trust funds—equity securities U.S. large-cap 96 — 96 — 23 % U.S. small and mid-cap 17 — 17 — 4 % Emerging markets 19 — 19 — 5 % Total equity investments 132 — 132 — 31 % Emerging markets bond fund 26 — — 26 6 % Common/collective trust funds and corporate bonds —fixed income securities Intermediate-term investment grade U.S. government/ corporate bonds 54 — 54 — 13 % Mutual funds Long duration corporate bonds 126 — 126 — 30 % U.S. Treasury Inflation-Protected Securities (TIPs) 24 24 — — 6 % Convertible securities 14 14 — — 3 % Private investment fund—high yield securities 12 — — 12 3 % Total fixed-income investments 256 38 180 38 61 % Other investment—private real estate fund 27 — — 27 6 % Total Assets $ 420 $ 38 $ 317 $ 65 100 % Fair Value Measurement as of December 31, 2021 Asset Category Balance Level 1 Level 2 Measured using NAV practical expedient (1) % of total Cash and cash equivalent $ 4 $ — $ 4 $ — 1 % Common/collective trust funds—equity securities U.S. large-cap 135 — 135 — 25 % U.S. small and mid-cap 23 — 23 — 4 % Emerging markets 27 — 27 — 5 % Total equity investments 185 — 185 — 34 % Emerging markets bond fund 30 — — 30 6 % Common/collective trust funds and corporate bonds —fixed income securities Intermediate-term investment grade U.S. government/ corporate bonds 68 — 68 — 13 % Mutual funds Long duration corporate bonds 177 — 177 — 33 % U.S. Treasury Inflation-Protected Securities (TIPs) 24 24 — — 4 % Convertible securities 17 17 3 % Private investment fund—high yield securities 14 — — 14 3 % Total fixed-income investments 330 41 245 44 61 % Other investment—private real estate debt fund 25 — — 25 4 % Total Assets $ 544 $ 41 $ 434 $ 69 100 % (1) Investments are measured using the net asset value per share (or its equivalent) practical expedient and have not been categorized in the fair value hierarchy. The fair value amounts presented in the table are intended to permit a reconciliation of the fair value hierarchy to the value of the total plan assets. Cash and cash equivalents are primarily comprised of investments in money market mutual funds. In determining fair value, Level 1 investments are valued based on quoted market prices in active markets. Investments in common/collective trust and private mutual funds are valued using the NAV per unit in each fund. The NAV is based on the value of the underlying investments owned by each fund, minus its liabilities, and then divided by the number of shares outstanding. Common/collective trust funds and the private mutual fund are categorized in Level 2 to the extent that they are considered to have a readily determinable fair value. Investments for which fair value is estimated by using the NAV per share (or its equivalent) as a practical expedient are not categorized in the fair value hierarchy. Except for the Company’s U.S. funded pension plan, all of Moody’s Retirement Plans are unfunded and therefore have no plan assets. Cash Flows The Company did not contribute to its U.S. funded pension plan during the years ended December 31, 2022 and 2021. The Company made payments of $7 million and $50 million related to its U.S. unfunded pension plan obligations during the years ended December 31, 2022 and 2021, respectively. The Company currently does not anticipate making a contribution to its funded pension plan in 2023, and anticipates making payments of $6 million related to its unfunded U.S. pension plans and immaterial payments related to its other Retirement Plans during the year ended December 31, 2023. Estimated Future Benefits Payable Estimated future benefits payments for the Retirement Plans are as follows as of the year ended December 31, 2022: Year Ending December 31, Pension Plans Other Retirement Plans 2023 $ 22 $ 2 2024 25 2 2025 31 2 2026 29 2 2027 30 3 2028 - 2032 160 17 Defined Contribution Plans Moody’s has a Profit Participation Plan covering substantially all U.S. employees. The Profit Participation Plan provides for an employee salary deferral and the Company matches employee contributions, equal to 50% of employee contribution up to a maximum of 3% of the employee’s pay. Effective January 1, 2008, all new hires are automatically enrolled in the Profit Participation Plan when they meet eligibility requirements unless they decline participation. As the Company’s U.S. DBPPs are closed to new entrants effective January 1, 2008, all eligible new hires will instead receive a retirement contribution into the Profit Participation Plan in value similar to the pension benefits. Additionally, effective January 1, 2008, the Company implemented a deferred compensation plan in the U.S., which is unfunded and provides for employee deferral of compensation and Company matching contributions related to compensation in excess of the IRS limitations on benefits and contributions under qualified retirement plans. Total expenses associated with U.S. defined contribution plans were $35 million, $54 million and $44 million in the years ended December 31, 2022, 2021 and 2020, respectively. Effective January 1, 2008, Moody’s has designated the Moody’s Stock Fund, an investment option under the Profit Participation Plan, as an Employee Stock Ownership Plan and, as a result, participants in the Moody’s Stock Fund may receive dividends in cash or may reinvest such dividends into the Moody’s Stock Fund. Moody’s paid approximately $1 million during each of the years ended December 31, 2022, 2021, and 2020, respectively, for the Company’s common shares held by the Moody’s Stock Fund. The Company records the dividends as a reduction of retained earnings in the Consolidated Statements of Shareholders’ Equity. The Moody’s Stock Fund held approximately 329,300 and 328,500 shares of Moody’s common stock at December 31, 2022 and 2021, respectively. Non-U.S. Plans

STOCK-BASED COMPENSATION PLANS

STOCK-BASED COMPENSATION PLANS	12 Months Ended

Share-Based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION PLANS	STOCK-BASED COMPENSATION PLANS Under the 1998 Plan, 33.0 million shares of the Company’s common stock have been reserved for issuance. The 2001 Plan, which is shareholder approved, permits the granting of up to 50.6 million shares, of which not more than 14.0 million shares are available for grants of awards other than stock options. The stock plans also provide for the granting of restricted stock. The stock plans provide that options are exercisable not later than ten years from the grant date. The vesting period for awards under the stock plans is generally determined by the Board at the date of the grant and has been four years except for employees who are at or near retirement eligibility, as defined, for which vesting is between one The Company maintains the Directors’ Plan for its Board, which permits the granting of awards in the form of non-qualified stock options, restricted stock or performance shares. The vesting period is determined by the Board at the date of the grant and is generally one year for both options and restricted stock. Under the Directors’ Plan, 1.7 million shares of common stock were reserved for issuance. Any director of the Company who is not an employee of the Company or any of its subsidiaries as of the date that an award is granted is eligible to participate in the Directors’ Plan. On September 15, 2021, the Company acquired RMS, which is discussed in more detail in Note 9. As part of the acquisition, the Company registered the RMS 2014 Equity Award Plan and the RMS 2015 Equity Incentive Plan (collectively, "RMS Plans") as part of the purchase agreement to acquire RMS. Under the RMS Plans, 1.2 million shares of the Company’s common stock have been reserved for issuance. The RMS Plans provide that options are exercisable not later than ten years from the grant date. The vesting period is generally determined by the Board at the date of the grant and is four years for both options and restricted stock granted during 2021. As a result of the acquisition, certain RMS employees' unvested equity awards (employee stock options and restricted stock) with an acquisition-date fair value of $33 million were converted into equity awards of the Company based on an exchange ratio as defined in the purchase agreement. The portion of the fair value of the replacement awards related to services provided prior to the acquisition was $5 million and was accounted for as consideration transferred (See Note 9). The remaining portion of the replacement awards of $28 million, which is associated with post-acquisition service requirements, will be recognized as compensation expense over the remaining vesting period. Presented below is a summary of the stock-based compensation expense and associated tax benefit in the accompanying consolidated statements of operations: Year Ended December 31, 2022 2021 2020 Stock-based compensation expense $ 169 $ 175 $ 154 Tax benefit $ 41 $ 42 $ 30 The fair value of each employee stock option award is estimated on the date of grant using the Black-Scholes option-pricing model that uses the assumptions noted below. The expected dividend yield is derived from the annual dividend rate on the date of grant. The expected stock volatility is based on an assessment of historical weekly stock prices of the Company as well as implied volatility from Moody’s traded options. The risk-free interest rate is based on U.S. government zero coupon bonds with maturities similar to the expected holding period. The expected holding period is determined by examining historical and projected post-vesting exercise behavior activity. The following weighted average assumptions were used for options granted (excluding the aforementioned RMS replacement awards for the year ended December 31, 2021): Year Ended December 31, 2022 2021 2020 Expected dividend yield 0.86 % 0.89 % 0.80 % Expected stock volatility 27 % 28 % 23 % Risk-free interest rate 1.91 % 0.82 % 1.43 % Expected holding period (in years) 5.6 5.6 5.7 Due to the RMS replacement option awards being heavily in-the-money at the acquisition date, the Company utilized a binomial valuation approach in 2021 to determine the fair value of the options, which approximated the intrinsic value of the replaced awards at the acquisition date. The following represents the fair value of the options at grant date (including the RMS replacement option awards for the year ended December 31, 2021): Year Ended December 31, 2022 2021 2020 Weighted average grant date fair value per share $ 84.00 $ 121.14 $ 60.66 A summary of option activity as of December 31, 2022 and changes during the year then ended is presented below: Options Shares Weighted Average Exercise Price Per Share Weighted Average Remaining Contractual Term Aggregate Intrinsic Value Outstanding, December 31, 2021 1.0 $ 166.16 Granted 0.1 $ 324.64 Exercised (0.1) $ 148.28 Outstanding, December 31, 2022 1.0 $ 181.35 5.2 years $ 107 Vested and expected to vest, December 31, 2022 1.0 $ 181.01 5.2 years $ 107 Exercisable, December 31, 2022 0.7 $ 139.08 4.0 years $ 99 The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between Moody’s closing stock price on the last trading day of the year ended December 31, 2022 and the exercise prices, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options as of December 31, 2022. This amount varies based on the fair value of Moody’s stock. As of December 31, 2022, there was $14 million of total unrecognized compensation expense related to options. The expense is expected to be recognized over a weighted average period of 2.0 years. The following table summarizes information relating to stock option exercises: Year Ended December 31, 2022 2021 2020 Proceeds from stock option exercises $ 8 $ 24 $ 39 Aggregate intrinsic value $ 9 $ 55 $ 132 Tax benefit realized upon exercise $ 2 $ 13 $ 32 A summary of nonvested restricted stock activity for the year ended December 31, 2022 is presented below: Nonvested Restricted Stock Shares Weighted Average Grant Date Fair Value Per Share Balance, December 31, 2021 1.4 $ 253.85 Granted 0.6 $ 318.88 Vested (0.6) $ 229.86 Forfeited (0.1) $ 281.24 Balance, December 31, 2022 1.3 $ 288.47 As of December 31, 2022, there was $216 million of total unrecognized compensation expense related to nonvested restricted stock. The expense is expected to be recognized over a weighted average period of 2.4 years. The following table summarizes information relating to the vesting of restricted stock awards: Year Ended December 31, 2022 2021 2020 Fair value of shares vested $ 180 $ 194 $ 202 Tax benefit realized upon vesting $ 42 $ 46 $ 46 A summary of performance-based restricted stock activity for the year ended December 31, 2022 is presented below: Performance-based restricted stock Shares Weighted Average Grant Date Fair Value Per Share Balance, December 31, 2021 0.4 $ 266.89 Granted 0.1 $ 310.62 Vested (0.2) $ 169.80 Balance, December 31, 2022 0.3 $ 303.80 The following table summarizes information relating to the vesting of the Company’s performance-based restricted stock awards: Year Ended December 31, 2022 2021 2020 Fair value of shares vested $ 50 $ 28 $ 70 Tax benefit realized upon vesting $ 7 $ 7 $ 17 As of December 31, 2022, there was $22 million of total unrecognized compensation expense related to this plan. The expense is expected to be recognized over a weighted average period of 1.4 years. The Company has a policy of issuing treasury stock to satisfy shares issued under stock-based compensation plans. In addition, the Company also sponsors the ESPP. Under the ESPP, 6 million shares of common stock were reserved for issuance. The ESPP permits eligible employees to purchase common stock of the Company on a monthly basis at a discount to the average of the high and the low trading prices on the New York Stock Exchange on the last trading day of each month. This discount was 5% in 2022, 2021, and 2020 resulting in the ESPP qualifying for non-compensatory status under Topic 718 of the ASC. Accordingly, no compensation expense was recognized for the ESPP in 2022, 2021, and 2020. The employee purchases are funded through after-tax payroll deductions, which plan participants can elect from one percent to ten percent of compensation, subject to the annual federal limit.

The Tax Act includes a mandatory one-time deemed repatriation tax (“transition tax”) on previously untaxed accumulated earnings of foreign subsidiaries and beginning in 2018 reduces the statutory federal corporate income tax rate from 35% to 21%. Accordingly, the Company determined the transition tax to be $236 million, with the remaining balance due of $48 million as of December 31, 2022. As a result of the Tax Act, all previously net undistributed foreign earnings have now been subject to U.S. tax. The Company regularly evaluates which entities it will indefinitely reinvest earnings. The Company has provided deferred taxes for those entities whose earnings are not considered indefinitely reinvested. The Company’s annual tax expense for the year ended December 31, 2022 includes Excess Tax Benefits from stock compensation of $19 million, benefits from the resolution of certain UTPs of $30 million and other net increases to tax positions of $12 million. The Company had valuation allowances of $21 million and $18 million at December 31, 2022 and 2021, respectively, related to foreign net operating losses for which realization is uncertain. As of December 31, 2022, the Company had $322 million of UTPs of which $297 million represents the amount that, if recognized, would impact the effective tax rate in future periods. The decrease in 2022 resulted primarily from lapses in statutes of limitation for non-U.S. jurisdictions along with state income tax settlement payments. The decrease in 2021 resulted primarily from the resolutions of uncertain tax positions. The increase in 2020 was primarily due to the additional reserves established for non-U.S. tax exposures. A reconciliation of the beginning and ending amount of UTPs is as follows: Year Ended December 31, 2022 2021 2020 Balance as of January 1 $ 388 $ 483 $ 477 Additions for tax positions related to the current year 12 102 37 Additions for tax positions of prior years 12 18 17 Reductions for tax positions of prior years (27) — (2) Settlements with taxing authorities (30) (134) (5) Lapse of statute of limitations (33) (81) (41) Balance as of December 31 $ 322 $ 388 $ 483 The Company classifies interest related to UTPs in interest expense in its consolidated statements of operations. Penalties, if incurred, are recognized in other non-operating (expense) income, net. Refer to Note 18 for disclosure of interest (expense) income relating to UTPs and other tax-related liabilities. As of December 31, 2022, 2021 and 2020 the amount of accrued interest recorded in the Company’s consolidated balance sheets related to UTPs was $47 million, $59 million and $113 million, respectively. 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 City tax returns for 2015 through 2017 are currently under examination. After the resolution of a tax audit for 2012, certain of the Company’s U.K. subsidiaries’ returns from 2012 to 2021 remain open to examination. For current ongoing matters related to open tax years, the Company estimates that it is reasonably possible that a significant portion of the balance of UTPs could decrease in the next twelve months as a result of the effective settlement of these audits. Given the number of years and nature of matters that remain subject to examination in various tax jurisdictions both in the U.S. and internationally, the Company is unable to estimate a range of possible changes to its UTPs for 2023. It is also possible that new issues might be raised by tax authorities which might necessitate increases to the balance of UTPs. As the Company is unable to predict the timing of conclusion of these audits, the Company 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 ASC Topic 740. 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.

INDEBTEDNESS	INDEBTEDNESS The Company’s debt is recorded at its carrying amount, which represents the issuance amount plus or minus any issuance premium or discount, except for certain debt as depicted in the table below, which is recorded at the carrying amount adjusted for the fair value of an interest rate swap used to hedge the fair value of the note. The following table summarizes total indebtedness: December 31, 2022 Principal Amount Fair Value of Interest Rate Swaps (1) Unamortized (Discount) Premium Unamortized Debt Issuance Costs Carrying Value Notes Payable: 4.875% 2013 Senior Notes, due 2024 $ 500 $ — $ (1) $ (1) $ 498 5.25% 2014 Senior Notes, due 2044 600 (42) 3 (4) 557 1.75% 2015 Senior Notes, due 2027 534 — — (2) 532 3.25% 2017 Senior Notes, due 2028 500 (37) (3) (2) 458 4.25% 2018 Senior Notes, due 2029 400 (42) (2) (2) 354 4.875% 2018 Senior Notes, due 2048 400 (44) (6) (4) 346 0.950% 2019 Senior Notes, due 2030 800 — (2) (4) 794 3.75% 2020 Senior Notes, due 2025 700 (27) (1) (3) 669 3.25% 2020 Senior Notes, due 2050 300 — (4) (3) 293 2.55% 2020 Senior Notes, due 2060 300 — (2) (3) 295 2.00% 2021 Senior Notes, due 2031 600 — (7) (4) 589 2.75% 2021 Senior Notes, due 2041 600 — (13) (5) 582 3.10% 2021 Senior Notes, due 2061 500 — (7) (5) 488 3.75% 2022 Senior Notes, due 2052 500 (35) (8) (5) 452 4.25% 2022 Senior Notes, due 2032 500 (12) (2) (4) 482 Total long-term debt $ 7,734 $ (239) $ (55) $ (51) $ 7,389 December 31, 2021 Principal Amount Fair Value of Interest Rate Swaps (1) Unamortized (Discount) Premium Unamortized Debt Issuance Costs Carrying Value Notes Payable: 4.875% 2013 Senior Notes, due 2024 $ 500 $ — $ (1) $ (1) $ 498 5.25% 2014 Senior Notes, due 2044 600 (7) 3 (5) 591 1.75% 2015 Senior Notes due 2027 568 — — (2) 566 2.625% 2017 Senior Notes, due 2023 500 5 — (1) 504 3.25% 2017 Senior Notes, due 2028 500 8 (3) (2) 503 4.25% 2018 Senior Notes, due 2029 400 — (2) (2) 396 4.875% 2018 Senior Notes, due 2048 400 (7) (6) (4) 383 0.950% 2019 Senior Notes, due 2030 853 — (2) (5) 846 3.75% 2020 Senior Notes, due 2025 700 (9) (1) (4) 686 3.25% 2020 Senior Notes, due 2050 300 — (4) (3) 293 2.55% 2020 Senior Notes, due 2060 500 — (4) (5) 491 2.00% 2021 Senior Notes, due 2031 600 — (8) (5) 587 2.75% 2021 Senior Notes, due 2041 600 — (13) (6) 581 3.10% 2021 Senior Notes, due 2061 500 — (7) (5) 488 Total long-term debt $ 7,521 $ (10) $ (48) $ (50) $ 7,413 (1) The fair value of interest rate swaps in the tables above represents the cumulative amount of fair value hedging adjustments included in the carrying amount of the hedged debt. Credit Facility The following summarizes information relating to the Company's revolving credit facility: December 31, 2022 December 31, 2021 Issue Date Capacity Maturity Drawn Undrawn Drawn Undrawn 2021 Credit Facility December 17, 2021 $ 1,250 December 17, 2026 $ — $ 1,250 $ — $ 1,250 Interest on borrowings under the 2021 Credit Facility is payable at rates that are based on an adjusted term SOFR Rate plus a premium that can range from 80.5 basis points to 122.5 basis points, depending on the Company’s index debt ratings, as set forth in the 2021 Facility Agreement. The Company also has the option to choose other rates, such as those based on adjusted Daily Simple SOFR or an alternate base rate as set forth in the 2021 Facility Agreement. The Company also pays quarterly facility fees, regardless of borrowing activity under the Facility. The quarterly fees for the 2021 Facility can range from 7 basis points of the 2021 Credit Facility amount to 15 basis points, depending on the Company’s index debt ratings. The facility fees for the 2021 Credit Facility are subject to sustainability-based pricing adjustments based on the Company’s annual performance with respect to certain spending with vendors who have committed to and publicly announced the setting of science-based targets to reduce greenhouse gas emissions. The 2021 Facility contains a financial covenant that requires the Company to maintain a total debt to EBITDA Ratio of (i) not more than 4 to 1 at the end of any fiscal quarter or (ii) not more than 4.5 to 1 as of the end of the first three consecutive quarters immediately following any acquisition with consideration in excess of $500 million, subject to certain conditions as set forth in the 2021 Facility. Commercial Paper On August 3, 2016, the Company entered into a private placement commercial paper program under which the Company may issue CP notes up to a maximum amount of $1.0 billion. Borrowings under the CP Program are backstopped by the 2021 Facility. Amounts under the CP Program may be re-borrowed. The maturity of the CP Notes will vary, but may not exceed 397 days from the date of issue. The CP Notes are sold at a discount from par, or alternatively, sold at par and bear interest at rates that will vary based upon market conditions. The rates of interest will depend on whether the CP Notes will be a fixed or floating rate. The interest on a floating rate may be based on the following: (a) certificate of deposit rate; (b) commercial paper rate; (c) the federal funds rate; (d) the LIBOR; (e) prime rate; (f) Treasury rate; or (g) such other base rate as may be specified in a supplement to the private placement agreement. The CP Program contains certain events of default including, among other things: non-payment of principal, interest or fees; entrance into any form of moratorium; and bankruptcy and insolvency events, subject in certain instances to cure periods. As of December 31, 2022, the Company has no CP borrowings outstanding. Notes Payable The Company may prepay certain of its senior notes, in whole or in part, but may incur a Make Whole amount penalty. During 2022, the Company issued the 2022 Senior Notes due 2052 and the 2022 Senior Notes due 2032. The key terms of these debt issuances are set forth in the table above. In 2022, the Company fully repaid $500 million of the 2017 Senior Notes due 2023 via a tender offer. Additionally, in December 2022, the Company repaid a portion of its outstanding 2.55% 2020 Senior Notes due 2060 via a partial tender offer. Pursuant to this tender offer, the Company early redeemed $200 million in principal amount of the notes for $126 million, resulting in a net $70 million gain on extinguishment. This gain on extinguishment is net of $4 million related to unamortized discounts and debt issuance costs associated with the principal amount that was repaid. At December 31, 2022, the Company was in compliance with all covenants contained within all of the debt agreements. All the debt agreements contain cross default provisions which state that default under one of the aforementioned debt instruments could in turn permit lenders under other debt instruments to declare borrowings outstanding under those instruments to be immediately due and payable. As of December 31, 2022, there were no such cross defaults. The repayment schedule for the Company’s borrowings is as follows: Year Ending December 31, Total 2023 $ — 2024 500 2025 700 2026 — 2027 534 Thereafter 6,000 Total $ 7,734 Interest expense, net The following table summarizes the components of interest as presented in the consolidated statements of operations: Year Ended December 31, 2022 2021 2020 Expense on borrowings $ (216) $ (185) $ (163) (Expense) income on UTPs and other tax related liabilities (1) (13) 21 (34) Net periodic pension costs - interest component (17) (16) (19) Income 15 9 11 Interest expense, net $ (231) $ (171) $ (205) Interest paid (2) $ 198 $ 162 $ 132 (1) The amount for the year ended December 31, 2021 includes a $45 million benefit relating to the reversal of tax-related interest accruals pursuant to the resolution of tax matters. (2) Interest paid includes net settlements on interest rate swaps more fully discussed in Note 7. The fair value and carrying value of the Company’s debt as of December 31, 2022 and 2021 are as follows: December 31, 2022 December 31, 2021 Carrying Amount Estimated Fair Value Carrying Amount Estimated Fair Value Long-term debt $ 7,389 $ 6,564 $ 7,413 $ 7,982 The fair value of the Company’s debt is estimated based on quoted prices in active markets as of the reporting date, which are considered Level 1 inputs within the fair value hierarchy.

CONTINGENCIES

CONTINGENCIES	12 Months Ended

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 17 to the 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. In view of the inherent difficulty of assessing the potential outcome of legal proceedings, governmental, regulatory and legislative investigations and inquiries, claims and litigation and similar matters and contingencies, particularly when the claimants seek large or indeterminate damages or assert novel legal theories or the matters involve a large number of parties, the Company often cannot predict what the eventual outcome of the pending matters will be or the timing of any resolution of such matters. The Company also may be unable to predict the impact (if any) that any such matters may have on how its business is conducted, on its competitive position or on its financial position, results of operations or cash flows. As the process to resolve any pending matters progresses, management will continue to review the latest information available and assess its ability to predict the outcome of such matters and the effects, if any, on its operations and financial condition and to accrue for and disclose such matters as and when required. However, because such matters are inherently unpredictable and unfavorable developments or resolutions can occur, the ultimate outcome of such matters, including the amount of any loss, may differ from those estimates.

SEGMENT INFORMATION

SEGMENT INFORMATION	12 Months Ended
	Dec. 31, 2022
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, SFG, FIG and PPIF 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 3 for further details on the components of the Company’s revenue.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
New Accounting Pronouncements	Adoption of New Accounting Standards in 2022 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 Company may elect to apply the amendments prospectively through December 31, 2024 as the transition from LIBOR is completed. As of December 31, 2022, the Company has interest rate swaps designated as fair value hedges and cross currency swaps designated as net investment hedges referencing three-month or six-month USD LIBOR with aggregate notional amounts as disclosed in Note 7. For derivative instruments that will be outstanding at the transition date, the Company intends to modify the contractual terms of the instruments to replace LIBOR with another reference rate, such as SOFR. Pursuant to the modification of the contractual terms of these instruments, the Company intends to utilize the various optional expedients set forth in ASC Topic 848 relating to derivative instruments used in hedging relationships. 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.
Basis of Consolidation	Basis of Consolidation The consolidated financial statements include those of Moody’s Corporation and its majority- and wholly-owned subsidiaries. The effects of all intercompany transactions have been eliminated. Investments in companies for which the Company has significant influence over operating and financial policies but not a controlling interest are accounted for on an equity basis whereby the Company records its proportional share of the investment’s net income or loss as part of other non-operating income (expense), net and any dividends received reduce the carrying amount of the investment. Equity investments without a readily determinable fair value for which the Company does not have significant influence are accounted for under the ASC 321 measurement alternative; these investments are recorded at initial cost, less impairment, adjusted upward or downward for any observable price changes in similar investments. The Company applies the guidelines set forth in Topic 810 of the ASC in assessing its interests in variable interest entities to decide whether to consolidate an entity. The Company has reviewed the potential variable interest entities and determined that there are no consolidation requirements under Topic 810 of the ASC. The Company consolidates its ICRA subsidiaries on a three month lag.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash equivalents principally consist of investments in money market deposit accounts as well as certificates of deposit with maturities of three months or less when purchased.
Short-term Investments	Short-term Investments Short-term investments are securities with maturities greater than 90 days at the time of purchase that are available for operations in the next 12 months. The Company’s short-term investments primarily consist of certificates of deposit and their cost approximates fair value due to the short-term nature of the instruments. Interest and dividends on these investments are recorded into income when earned.
Property and Equipment	Property and Equipment Property and equipment are stated at cost and are depreciated using the straight-line method over their estimated useful lives. Expenditures for maintenance and repairs that do not extend the economic useful life of the related assets are charged to expense as incurred.
Computer Software Developed or Obtained for Internal Use	Computer Software Developed or Obtained for Internal Use The Company capitalizes costs related to software developed or obtained for internal use. These assets, included in property and equipment in the consolidated balance sheets, relate to the Company’s financial, website and other systems. Such costs generally consist of direct costs for third-party license fees, professional services provided by third parties and employee compensation, in each case incurred either during the application development stage or in connection with upgrades and enhancements that increase functionality. Such costs are depreciated over their estimated useful lives on a straight-line basis. Costs incurred during the preliminary project stage of development as well as maintenance costs are expensed as incurred.
Goodwill and Other Acquired Intangible Assets	Goodwill and Other Acquired Intangible Assets Moody’s evaluates its goodwill for impairment at the reporting unit level, defined as an operating segment (i.e., MIS and MA), or one level below an operating segment (i.e., a component of an operating segment), annually as of July 31 or more frequently if impairment indicators arise in accordance with ASC Topic 350. The Company evaluates the recoverability of goodwill using a two-step impairment test approach at the reporting unit level. In the first step, the Company assesses various qualitative factors to determine whether the fair value of a reporting unit may be less than its carrying amount. If a determination is made based on the qualitative factors that an impairment does not exist, the Company is not required to perform further testing. If the aforementioned qualitative assessment results in the Company concluding that it is more likely than not that the fair value of a reporting unit may be less than its carrying amount, the fair value of the reporting unit will be quantitatively determined and compared to its carrying value including goodwill. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, goodwill is not impaired and the Company is not required to perform further testing. If the fair value of the reporting unit is less than the carrying value, the Company will record a goodwill impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value. The Company evaluates its reporting units on an annual basis, or more frequently if there are changes in the reporting structure of the Company due to acquisitions, reporting unit realignments or if there are indicators of potential impairment. For the reporting units where the Company is consistently able to conclude that no impairment exists using only a qualitative approach, the Company’s accounting policy is to perform the second step of the aforementioned goodwill impairment assessment at least once every three years. Goodwill is assigned to a reporting unit at the date when an acquisition is integrated into one of the established reporting units, and is based on which reporting unit is expected to benefit from the synergies of the acquisition. For purposes of assessing the recoverability of goodwill, the Company has four reporting units: two within the Company’s ratings business (one for the ICRA business and one that encompasses all of Moody’s other ratings operations) and two reporting units within MA consisting of businesses that offer: i) data and data-driven analytical solutions; and ii) risk-management software, workflow and CRE solutions.
Impairment of long-lived assets and definite-lived intangible assets	Impairment of long-lived assets and definite-lived intangible assets Long-lived assets (including ROU Assets) and amortizable intangible assets are reviewed for recoverability whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.
Stock-Based Compensation	Stock-Based Compensation The Company records compensation expense over the requisite service period for all share-based payment award transactions granted to employees based on the fair value of the equity instrument at the time of grant. This includes shares issued under stock option and restricted stock plans.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Based on the Company’s risk management policy, the Company may use derivative financial instruments to reduce exposure to changes in foreign exchange rates and interest rates. The Company does not enter into derivative financial instruments for speculative purposes. All derivative financial instruments are recorded on the balance sheet at their respective fair values on a gross basis. The changes in the value of derivatives that qualify as fair value hedges are recorded in the same income statement line item in earnings in which the corresponding adjustment to the carrying value of the hedged item is presented. The entire change in the fair value of derivatives that qualify as cash flow hedges is recorded to OCI and such amounts are reclassified from AOCI(L) to the same income statement line in earnings in the same period or periods during which the hedged transaction affects income. The Company assesses effectiveness for net investment hedges using the spot-method. The entire change in the fair value of derivatives that qualify as net investment hedges is initially recorded to OCI. Those changes in fair value attributable to components included in the assessment of hedge effectiveness in a net investment hedge are recorded in the currency translation adjustment component of OCI and remain in AOCI(L) until the period in which the hedged item affects earnings. Those changes in fair value attributable to components excluded from the assessment of hedge effectiveness in a net investment hedge are recorded to OCI and amortized to earnings using a systematic and rational method over the duration of the hedge. Any changes in the fair value of derivatives that the Company does not designate as hedging instruments under Topic 815 of the ASC are recorded in the consolidated statements of operations in the period in which they occur.
Revenue Recognition and Costs to Obtain or Fulfill a Contract with a Customer	Revenue Recognition and Costs to Obtain or Fulfill a Contract with a Customer Revenue recognition: Revenue is recognized when control of promised goods or services is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. When contracts with customers contain multiple performance obligations, the Company accounts for individual performance obligations separately if they are distinct. The transaction price is allocated to each distinct performance obligation on a relative SSP basis. The Company determines the SSP by using the price charged for a deliverable when sold separately or uses management’s best estimate of SSP for goods or services not sold separately using estimation techniques that maximize observable data points, including: internal factors relevant to its pricing practices such as costs and margin objectives; standalone sales prices of similar products; pricing policies; percentage of the fee charged for a primary product or service relative to a related product or service; and customer segment and geography. Additional consideration is also given to market conditions such as competitor pricing strategies and market trends. Sales, usage-based, value added and other taxes are excluded from revenues. MIS Revenue In the MIS segment, revenue arrangements with multiple elements are generally comprised of two distinct performance obligations, a rating and the related monitoring service. Revenue attributed to ratings of issued securities is generally recognized when the rating is delivered to the issuer. Revenue attributed to monitoring of issuers or issued securities is recognized ratably over the period in which the monitoring is performed, generally one year. In the case of certain structured finance products, primarily CMBS, issuers can elect to pay all of the annual monitoring fees upfront. These fees are deferred and recognized over the future monitoring periods based on the expected lives of the rated securities. MIS arrangements generally have standard contractual terms for which the stated payments are due at conclusion of the ratings process for ratings and either upfront or in arrears for monitoring services; and are signed by customers either on a per issue basis or at the beginning of the relationship with the customer. In situations when customer fees for an arrangement may be variable, the Company estimates the variable consideration at inception using the expected value method based on analysis of similar contracts in the same line of business, which is constrained based on the Company’s assessment of the realization of the adjustment amount. The Company allocates the transaction price within arrangements that include multiple performance obligations based upon the relative SSP of each service. The SSP for both rating and monitoring services is generally based upon observable selling prices where the rating or monitoring service is sold separately to similar customers. MA Revenue In the MA segment, products and services offered by the Company include hosted research and data subscriptions, installed and hosted software subscriptions, perpetual installed software licenses and related maintenance, or PCS, and professional services. Subscription and PCS contracts are generally invoiced in advance of the contractual coverage period, which is principally one year, but can range from 3-5 years. Perpetual software licenses are generally invoiced upon delivery and professional services are invoiced as those services are provided. Payment terms and conditions vary by contract type, but primarily include a requirement of payment within 30 to 60 days. Revenue from research, data and other hosted subscriptions is recognized ratably over the related subscription period as MA's performance obligation to provide access to these products is progressively fulfilled over the stated term of the contract. A large portion of these services are invoiced in the months of November, December and January. Revenue from the sale of a software license, when considered distinct from the related software implementation services, is generally recognized at the time the product master or first copy is delivered or transferred to the customer. PCS is generally recognized ratably over the contractual period commencing when the software license is fully delivered. Revenue from installed software subscriptions, which includes PCS, is bifurcated into a software license performance obligation and a PCS performance obligation, which follow the patterns of recognition described above. For implementation services and other service projects for which fees are fixed, the Company determined progress towards completion is most accurately measured on a percentage-of-completion basis (input method) as this approach utilizes the most directly observable data points and is therefore used to recognize the related revenue. For implementation services where price varies based on time expended, a time-based measure of progress towards completion of the performance obligation is utilized. Revenue from professional services rendered is generally recognized over time as the services are performed. Products and services offered within the MA segment are sold either stand-alone or together in various combinations. In instances where an arrangement contains multiple performance obligations, the Company accounts for the individual performance obligations separately if they are considered distinct. Revenue is generally allocated to all performance obligations based upon the relative SSP at contract inception. For certain performance obligations, judgment is required to determine the SSP. Revenue is recognized for each performance obligation based upon the conditions for revenue recognition noted above. In the MA segment, customers usually pay a fixed fee for the products and services based on signed contracts. However, accounting for variable consideration is applied mainly for: i) estimates for cancellation rights and price concessions and ii) T&M based services. The Company estimates the variable consideration associated with cancellation rights and price concessions based on the expected amount to be provided to customers and reduces the amount of revenue to be recognized. Costs to Obtain or Fulfill a Contract with a Customer: Costs to obtain a contract with a customer Costs incurred to obtain customer contracts, such as sales commissions, are deferred and recorded within other current assets and other assets when such costs are determined to be incremental to obtaining a contract, would not have been incurred otherwise and the Company expects to recover those costs. These costs are amortized to expense on a systematic basis consistent with the transfer of the products or services to the customer. Depending on the line of business to which the contract relates, this may be based upon the average economic life of the products sold or average period for which services are provided, inclusive of anticipated contract renewals. Determining the estimated economic life of the products sold requires judgment with respect to anticipated future technological changes. Costs to obtain customer contracts are only incurred in the MA segment. Cost to fulfill a contract with a customer Costs incurred to fulfill customer contracts, are deferred and recorded within other current assets and other assets when such costs relate directly to a contract, generate or enhance resources of the Company that will be used in satisfying performance obligations in the future and the Company expects to recover those costs.
Accounts Receivable Allowances	Accounts Receivable Allowances In order to determine an estimate of expected credit losses, receivables are segmented based on similar risk characteristics including historical credit loss patterns and industry or class of customers to calculate reserve rates. The Company uses an aging method for developing its allowance for credit losses by which receivable balances are stratified based on aging category. A reserve rate is calculated for each aging category which is generally based on historical information, and is adjusted, when necessary, for current conditions (e.g., macroeconomic or industry related) and reasonable and supportable forecasts about the future. The Company also considers customer specific information (e.g., bankruptcy or financial difficulty) when estimating its expected credit losses, as well as the economic environment of the customers, both from an industry and geographic perspective, in evaluating the need for allowances. Expected credit losses are reflected as additions to the accounts receivable allowance. Actual uncollectible account write-offs are recorded against the allowance.
Leases	Leases The Company has operating leases, which substantially all relate to the lease of office space. The Company’s leases which are classified as finance leases are not material to the consolidated financial statements. The Company determines if an arrangement meets the definition of a lease at contract inception. The Company recognizes in its consolidated balance sheet a lease liability and an ROU Asset for all leases with a lease term greater than 12 months. In determining the length of the lease term, the Company utilizes judgment in assessing the likelihood of whether it is reasonably certain that it will exercise an option to extend or early-terminate a lease, if such options are provided in the lease agreement. ROU Assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU Assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. As substantially all of the Company’s leases do not provide an implicit interest rate, the Company uses its estimated secured incremental borrowing rates at the lease commencement date in determining the present value of lease payments. These secured incremental borrowing rates are attributable to the currency in which the lease is denominated. At commencement, the Company’s initial measurement of the ROU Asset is calculated as the present value of the remaining lease payments (i.e., lease liability), with additive adjustments reflecting: initial direct costs (e.g., broker commissions) and prepaid lease payments (if any); and reduced by any lease incentives provided by the lessor if: (i) received before lease commencement or (ii) receipt of the lease incentive is contingent upon future events for which the occurrence is both probable and within the Company’s control. Lease expense for minimum operating lease payments is recognized on a straight-line basis over the lease term. This straight-line lease expense represents a single lease cost which is comprised of both an interest accretion component relating to the lease liability and amortization of the ROU Assets. The Company records this single lease cost in operating and SG&A expenses. However, in situations where an operating lease ROU Asset has been impaired, the subsequent amortization of the ROU Asset is then recorded on a straight-line basis over the remaining lease term and is combined with accretion expense on the lease liability to result in single operating lease cost (which subsequent to impairment will no longer follow a straight-line recognition pattern). The Company has lease agreements which include lease and non-lease components. For the Company’s office space leases, the lease components (e.g., fixed rent payments) and non-lease components (e.g., fixed common-area maintenance costs) are combined and accounted for as a single lease component. Variable lease payments (e.g. variable common-area-maintenance costs) are only included in the initial measurement of the lease liability to the extent those payments depend on an index or a rate. Variable lease payments not included in the lease liability are recognized in net income in the period in which the obligation for those payments is incurred.
Contingencies	Contingencies Moody’s is involved in legal and tax proceedings, governmental, regulatory and legislative investigations and inquiries, claims and litigation that are incidental to the Company’s business, including claims based on ratings assigned by MIS. Moody’s is also subject to ongoing tax audits in the normal course of business. Management periodically assesses the Company’s liabilities and contingencies in connection with these matters based upon the latest information available. Moody’s discloses material pending legal proceedings pursuant to SEC rules and other pending matters as it may determine to be appropriate. 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. In view of the inherent difficulty of assessing the potential outcome of legal proceedings, governmental, regulatory and legislative investigations and inquiries, claims and litigation and similar matters and contingencies, particularly when the claimants seek large or indeterminate damages or assert novel legal theories or the matters involve a large number of parties, the Company often cannot predict what the eventual outcome of the pending matters will be or the timing of any resolution of such matters. The Company also may be unable to predict the impact (if any) that any such matters may have on how its business is conducted, on its competitive position or on its financial position, results of operations or cash flows. As the process to resolve any pending matters progresses, management will continue to review the latest information available and assess its ability to predict the outcome of such matters and the effects, if any, on its operations and financial condition and to accrue for and disclose such matters as and when required. However, because such matters are inherently unpredictable and unfavorable developments or resolutions can occur, the ultimate outcome of such matters, including the amount of any loss, may differ from those estimates.
Operating Expenses	Operating Expenses Operating expenses include costs associated with the development and production of the Company’s products and services and their delivery to customers. These expenses principally include employee compensation and benefits and travel costs that are incurred in connection with these activities. Operating expenses are charged to income as incurred.
Selling, General and Administrative Expenses	Selling, General and Administrative Expenses SG&A expenses include such items as compensation and benefits for corporate officers and staff and compensation and other expenses related to sales. They also include items such as office rent, business insurance and professional fees. SG&A expenses are charged to income as incurred.
Foreign Currency Translation	Foreign Currency Translation For all operations outside the U.S. where the Company has designated the local currency as the functional currency, assets and liabilities are translated into U.S. dollars using end of year exchange rates, and revenue and expenses are translated using average exchange rates for the year. For these foreign operations, currency translation adjustments are recorded to other comprehensive income.
Comprehensive Income	Comprehensive Income Comprehensive income represents the change in net assets of a business enterprise during a period due to transactions and other events and circumstances from non-owner sources including: foreign currency translation impacts; net actuarial gains and losses and net prior service costs related to pension and other retirement plans; and gains and losses on derivative instruments designated as net investment hedges or cash flow hedges. Comprehensive income items, including cumulative translation adjustments of entities that are less-than-wholly-owned subsidiaries, will be reclassified to noncontrolling interests and thereby, adjusting accumulated other comprehensive income proportionately in accordance with the percentage of ownership interest of the non-controlling shareholder.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method in accordance with ASC Topic 740. Therefore, income tax expense is based on reported income before income taxes and deferred income taxes reflect the effect of temporary differences between the amounts of assets and liabilities that are recognized for financial reporting purposes and the amounts that are recognized for income tax purposes. The Company classifies interest related to unrecognized tax benefits as a component of interest expense in its consolidated statements of operations. Penalties are recognized in other non-operating expenses. For UTPs, the Company first determines whether it is more-likely-than-not (defined as a likelihood of more than fifty percent) that a tax position will be sustained based on its technical merits as of the reporting date, assuming that taxing authorities will examine the position and have full knowledge of all relevant information. A tax position that meets this more-likely-than-not threshold is then measured and recognized at the largest amount of benefit that is greater than fifty percent likely to be realized upon effective settlement with a taxing authority. On December 22, 2017, the Tax Act was signed into law, resulting in all previously undistributed foreign earnings being subject to U.S. tax. The Company has provided deferred taxes for those entities whose earnings are not considered indefinitely reinvested.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments include cash, cash equivalents, trade receivables and payables, and certain short-term investments consisting primarily of certificates of deposit and money market deposits, all of which are short-term in nature and, accordingly, approximate fair value. The Company also invests in mutual funds, which are accounted for as equity securities with readily determinable fair values under ASC Topic 321. The Company measures these investments at fair value with both realized gains and losses and unrealized holding gains and losses for these investments included in net income. Also, the Company uses derivative instruments to manage certain financial exposures that occur in the normal course of business. These derivative instruments are carried at fair value in the Company’s consolidated balance sheets. Fair value is defined by the ASC 820 as the price that would be received from selling an asset or paid to transfer a liability (i.e., an exit price) in an orderly transaction between market participants at the measurement date. The determination of this fair value is based on the principal or most advantageous market in which the Company could commence transactions and considers assumptions that market participants would use when pricing the asset or liability, such as inherent risk, transfer restrictions and risk of nonperformance. Also, determination of fair value assumes that market participants will consider the highest and best use of the asset. The ASC establishes a fair value hierarchy whereby the inputs contained in valuation techniques used to measure fair value are categorized into three broad levels as follows: Level 1: quoted market prices in active markets that the reporting entity has the ability to access at the date of the fair value measurement; Level 2: inputs other than quoted market prices described in Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value measurement of the assets or liabilities.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentration of credit risk principally consist of cash and cash equivalents, short-term investments, trade receivables and derivatives. For cash and cash equivalents, short-term investments and derivatives, the Company manages its credit exposure by limiting the amount of counterparty risk with any particular financial institution; limits are assigned to each counterparty based on perceived quality of credit, and are monitored daily. Cash equivalents are held among various money market deposit accounts and certificates of deposits as of December 31, 2022 and 2021. Short-term investments primarily consist of certificates of deposit as of December 31, 2022 and 2021. Derivatives primarily consist of foreign exchange forwards or swap contracts (interest rate swaps and cross-currency swaps) as of December 31, 2022 and 2021. For trade receivables, no customer accounted for 10% or more of accounts receivable at December 31, 2022 or 2021.
Earnings per Share of Common Stock	Earnings per Share of Common Stock Basic shares outstanding is calculated based on the weighted average number of shares of common stock outstanding during the reporting period. Diluted shares outstanding is calculated giving effect to all potentially dilutive common shares, assuming that such shares were outstanding and dilutive during the reporting period.
Pension and Other Retirement Benefits	Pension and Other Retirement Benefits Moody’s maintains various noncontributory DBPPs as well as other contributory and noncontributory retirement plans. The expense and assets/liabilities that the Company reports for its pension and other retirement benefits are dependent on many assumptions concerning the outcome of future events and circumstances. These assumptions represent the Company’s best estimates and may vary by plan. The differences between the assumptions for the expected long-term rate of return on plan assets and actual experience is spread over a five-year period to the market-related value of plan assets, which is used in determining the expected return on assets component of annual pension expense. All other actuarial gains and losses are generally deferred and amortized over the estimated average future working life of active plan participants. The Company recognizes as an asset or liability in its consolidated balance sheet the funded status of its defined benefit retirement plans, measured on a plan-by-plan basis. Changes in the funded status due to actuarial gains/losses are recorded as part of other comprehensive income during the period the changes occur.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates.

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.

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.
