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 (i.e., hosting 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; while 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 within the ERS and ESA businesses 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 as the services are performed over time. 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. T&M based contracts represent about half of MA’s service projects within the ERS and ESA businesses. The Company provides agreed upon services at a contracted daily or hourly rate. The commitment represents a series of goods and services that are substantially the same and have the same pattern of transfer to the customer. As such, if T&M services are sold with other MA products, the Company allocates the variable consideration entirely to the T&M performance obligation if the services are sold at standard pricing or at a similar discount level compared to other performance obligations in the same revenue contract. If these criteria are not met, the Company estimates variable consideration for each performance obligation upfront. Each form of variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal of any incremental revenue will not occur. 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, of 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, professional fees and gains and losses from sales and disposals of assets. 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. The Company manages its credit risk exposure by allocating its cash equivalents among various money market deposit accounts and certificates of deposits. Short-term investments primarily consist of certificates of deposit as of December 31, 2021 and 2020. The Company manages its credit risk exposure on cash equivalents and short-term investments by limiting the amount it can invest with any single entity. No customer accounted for 10% or more of accounts receivable at December 31, 2021 or 2020. 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 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 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. Recently Issued Accounting Pronouncements 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. Both ASU's were effective upon issuance, and the Company may elect to apply the amendments prospectively through December 31, 2022 as the transition from LIBOR is completed. As of December 31, 2021, 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 6. 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. In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" ("ASU No. 2021-08"). ASU No. 2021-08 will require 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. Under current GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 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. ASU No. 2021-08 is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company intends to early adopt this ASU effective January 1, 2022.

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.

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.

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 (i.e., hosting 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).

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.

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.

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.

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.

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.

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; while 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 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 within the ERS and ESA businesses 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.

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.

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. T&M based contracts represent about half of MA’s service projects within the ERS and ESA businesses. The Company provides agreed upon services at a contracted daily or hourly rate. The commitment represents a series of goods and services that are substantially the same and have the same pattern of transfer to the customer. As such, if T&M services are sold with other MA products, the Company allocates the variable consideration entirely to the T&M performance obligation if the services are sold at standard pricing or at a similar discount level compared to other performance obligations in the same revenue contract. If these criteria are not met, the Company estimates variable consideration for each performance obligation upfront. Each form of variable consideration is included in the transaction price only to the extent that it is probable that a significant reversal of any incremental revenue will not occur.

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.

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.

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).

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.

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 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.

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.

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.

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;

The Company manages its credit risk exposure by allocating its cash equivalents among various money market deposit accounts and certificates of deposits. Short-term investments primarily consist of certificates of deposit as of December 31, 2021 and 2020. The Company manages its credit risk exposure on cash equivalents and short-term investments by limiting the amount it can invest with any single entity. No customer accounted for 10% or more of accounts receivable at December 31, 2021 or 2020.

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 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 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. Both ASU's were effective upon issuance, and the Company may elect to apply the amendments prospectively through December 31, 2022 as the transition from LIBOR is completed.

As of December 31, 2021, 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 6. 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.

In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers" ("ASU No. 2021-08"). ASU No. 2021-08 will require 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. Under current GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 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. ASU No. 2021-08 is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company intends to early adopt this ASU effective January 1, 2022.
