Moody’s has two reportable segments: MIS and MA. MIS, the credit rating agency, publishes credit ratings on a wide range of debt obligations and the entities that i ssue such obligations in markets worldwide. Revenue is primarily derived from the originators and issuers of such transactions who use MIS ratings in the distribution of their debt issues to investors. Additionally, MIS earns revenue from certain non-ratin gs-related operations which consist primarily of the distribution of research and financial instrument pricing services in the Asia-Pacific region as well as revenue from ICRA’s non-ratings operations. The revenue from these operations is included in the M IS Other LOB and is not material to the results of the MIS segment. The MA segment develops a wide range of products and services that support financial analysis and risk management activities of institutional participants in global financial markets. With in its RD&A business, MA distributes research and data developed by MIS as part of its ratings process, including in-depth research on major debt issuers, industry studies and commentary on topical credit-related events. The RD&A business also produces economic research and data and analytical tools such as quantitative credit risk scores as well as business intelligence and company information products . Within its ERS business, MA provides software solutions as well as related risk management services. The PS business provides analytical and research services alon g with financial training and certification programs. These interim financial statements have been prepared in accordance with the instructions to Form 10-Q and should be read in conjunction with the Company’s consolidated financial statements and related notes in the Company’s 2016 annual report on Form 10-K filed with the SEC on February 25, 2017 .

As required by ASU 2016-09, Excess Tax Benefits or shortfalls recogniz ed on stock-based compensation expense are reflected in the consolidated statement of operations as a component of the provision for income taxes on a prospective basis. Prior to the adoption of this ASU, Excess Tax Benefits and shortfalls were recorded to capital surplus within shareholders’ deficit. The impact of this adoption was an $7.7 million and $35.6 million benefit to the provision for income taxes for the three and nine months ended September 30, 2017, respectively. Additionally, in accordance with this ASU, Excess Tax Benefits or shortfalls recognized on stock-based compensation are classified as operating cash flows in the consolidated statement of cash flows, and the Company has applied this provision on a retrospe ctive basis. Under previous accounting guidance, the Excess Tax Benefits or shortfalls were shown as a reduction to operating activity and an increase to financing activity. Furthermore, the Company has elected to continue to estimate the number of stock-b ased awards expected to vest, rather than accounting for award forfeitures as they occur, to determine the amount of stock-based compensation cost recognized in each period. The impact to the Company’s statement of cash flows for the nine months ended Sept ember 30, 2016 relating to the adoption of this provision of the ASU is set forth in the table below: (amounts in millions) As reported Nine Months Ended September 30, 2016 Adoption Adjustment Nine Months Ended September 30, 2016 As adjusted Net cash provided by operating activities $ 856.6 $ 32.4 $ 889.0 Net cash used in financing activities $ (882.6) $ (32.4) $ (915.0)

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: In accordance with the Company’s early adoption of ASU 2017-04, “Simplifying the Test for G oodwill Impairment (Topic 350)”, the Company has modified its accounting policy regarding long-lived assets, including goodwill and other acquired intangible assets. All other significant accounting policies described in the Form 10-K for the year ended December 31, 2016 remain unchanged. The Company’s revised acco unting policy regarding long-lived assets, including goodwill and other acquired intangible assets is disclosed below. Long-Lived Assets, including Goodwill and Other Acquired Intangible Assets Moody’s evaluates its goodwill for impairment at the reporting unit level, defined as an operating segment or one level below 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 tw o-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 that, based on the qualitative factors, 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 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 assigne d 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 recognize the difference as an impairment charge. The Company ev aluates its reporting units for impairment on an annual basis, or more frequently if there are changes in the reporting structure of the Company due to acquisitions or realignments or if there are indicators of potential impairment. For the reporting units where the Company is consistently able to conclude that an impairment does not exist 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 seven primary reporting units at September 30, 2017: two within the Company’s ratings business (one for the ICRA business and one that encompasses all of Moody’s other ratings operations) and f i ve reporting units within MA: RD&A, ERS, FSTC, MAKS and Bureau van Dijk. The RD&A reporting unit encompasses the distribution of investor-oriented research and data developed by MIS as part of its ratings process, in-depth research on major debt issuers, i ndustry studies, economic research and commentary on topical events and credit analytic tools. The ERS reporting unit consists of credit risk management and compliance software that is sold on a license or subscription basis as well as related advisory ser vices for implementation and maintenance. The FSTC reporting unit consists of the portion of the MA business that offers both credit training as well as other professional development training and certification services. The MAKS reporting unit consists of research and analytical services. The Bureau van Dijk reporting unit consists of business intelligence and company information products. Amortizable intangible assets are reviewed for recoverability whenever events or changes in circumstances indicate th at the carryin g amount may not be recoverable.

The Company also granted 1.0 million shares of restricted stock in the first nine months of 2017 , which had a weighted average grant date fair value of $113.39 per share. Both the employee stock options and restricted stock generally vest ratabl y over a four-year period. Additionally, the Company granted approximately 0.2 million shares of performance-based awards whereby the number of shares that ultimately vest are based on the achievement of certain non-market based performance metri cs of the Company over a three-year period. The weighted average grant date fair value of these awards was $109.36 per share. The following weighted average assumptions were used in determining the fair value for options granted in 2017 : Expected dividend yield 1.34% Expected stock volatility 26.8% Risk-free interest rate 2.19% Expected holding period 6.5 years Grant date fair value $30.00 Unrecognized compensation expense at September 30, 2017 was $8.0 million and $150.1 million for stock options and unvested restricted stock, respectively, which is expected to be recognized over a weighted average period of 1.4 years and 1.6 years, respectively . Additionally, there was $27.7 million of unrecognized compensation expense relating to the aforementioned non-market based performance-based awards, which is expected to be recognized over a weighted averag e period of 1.1 years.

INCOME TAXES

INCOME TAXES	NOTE 4 . INCOME TAXES Moody’s effective tax rate was 31.4% and 30.5% for the three months ended September 30, 2017 and 2016, respectively and 29.0% and 31.5% for the nine month periods ended September 30, 2017 and 2016, respectively. The increase for the three months ended September 30, 2017 is primarily due to the tax effects of a purchase price hedge gain and higher tax rates on non-US income, partially offset by Excess Tax Benefits of $7.7 million o n stock-based compensation, as further discussed in Note 1 above, which favorably benefited the ETR by approximately 160 BPS. The decrease in the ETR for the nine months ended September 30, 2017 was primarily due to Excess Tax Benefits of $35.6 million on stock-based compensation, as further discussed in Note 1, which favorably benefited the ETR by approximately 260 BPS coupled with the non-taxable CCXI Gain as discussed in Note 11 below. The Company classifies interest related to UTBs in interest expense, net in its consolidated statements of operations. Penalties, if incurred, would be recognized in other non-operating (expense) income, net. The Company had a net increase in its UTBs of $122.7 million ($122.6 million net of federal tax) during the third q uarter of 2017 and a net increase in its UTBs during the first nine months of 2017 of $136.6 million ($136.9 million net of federal tax). The increase in reserves is primarily due to the recording of UTBs in connection with the Bureau van Dijk acquisition . 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 the years 2011 and 2012 are under examination and its r eturns for 2013, 2014 and 2015 remain open to examination. The Company’s New York State tax returns for 2011 through 2014 are currently under examination and the Company’s New York City tax return for 2014 is currently under examination. The Company’s U.K. tax return for 2012 is currently under examination and its returns for 2013, 2014 and 2015 remain open to examination. For ongoing audits, it is possible the balance of UTBs could decrease in the next twelve months as a result of the settlement of these a udits, which might involve the payment of additional taxes, the adjustment of certain deferred taxes and/or the recognition of tax benefits. It is also possible that new issues might be raised by tax authorities which could necessitate increases to the bal ance of UTBs. As the Company is unable to predict the timing or outcome of these audits, it is therefore unable to estimate the amount of changes to the balance of UTBs at this time. However, the Company believes that it has adequately provided for its fin ancial exposure relating to all open tax years by tax jurisdiction in accordance with the applicable provisions of Topic 740 of the ASC regarding UTBs. On March 30, 2016, the FASB issued Accounting Standards Update (ASU) 2016-09, Improvements to Employee S hare Based Payment Accounting as more fully discussed in Note 1 to the condensed consolidated financial statements. The new guidance requires all tax effects related to share based payments to be recorded through the income statement. The Company has ado pted the new guidance as of the first quarter of 2017 and expects the adoption to result in a reduction in its income tax provision of approximately $40 million, or an approximate 225BPS reduction in the Company’s ETR for the full year of 2017. In the fi rst quarter of 2017, the Company adopted Accounting Standards Update 2016-16, Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory. Under previous guidance, the tax effects of intra-entity asset transfers (intercompany s ales) were deferred until the transferred asset was sold to a third party or otherwise recovered through use. The new guidance eliminates the exception for all intra-entity sales of assets other than inventory. Upon adoption, a cumulative-effect adjustmen t is recorded in retained earnings as of the beginning of the period of adoption. The net impact upon adoption is a reduction to retained earnings of $4.6 million. The Company does not expect any material impact on its future operations as a result of the adoption of this guidance. The following table shows the amount the Company paid for income taxes: Nine months ended September 30, 2017 2016 Income taxes paid* $ 194.7 $ 242.8 *The decrease in income taxes paid is primarily due to tax benefits relating to the Settlement Charge

The assumed proceeds in 2017 do not include Excess Tax Benefits pursuant to the prospective adoption of ASU 2016-09 in the first quarter of 2017. The assumed proceeds in 2016 include Excess Tax Benefits. The decrease in the diluted shares outst anding in the nine months ended September 30, 2017 primarily reflects treasury share repurchases under the Company’s Board authorized share repurch ase program.

ACQUISITIONS	NOTE 7 . ACQUISITIONS 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. Bureau van Dijk On August 10, 2017, a subsidiary of the Company acquired 100% of Yellow Maple I B.V., an indirect parent company of Bureau van Dijk Electronic Publishing B.V., a global provider of business intelligence and company information products . The cash payment of $3,542.0 million w as funded with a combination of cash on hand, primarily offshore, and new debt financing. The acquisition extends Moody’s position as a leader in risk data and analytical insight. Shown below is the preliminary purchase price allocation, which summarizes the fair value of the assets and liabilities assumed, at the date of acquisition: (Amounts in millions) Current assets $ 160.5 Property and equipment, net 4.2 Intangible assets: Customer relationships (23 year weighted average life) $ 998.7 Product technology (12 year weighted average life) 258.5 Trade name (18 year weighted average life) 82.2 Database (10 year weighted average life) 13.0 Total intangible assets (21 year weighted average life) 1,352.4 Goodwill 2,636.1 Other assets 4.3 Liabilities Deferred revenue $ (101.1) Accounts payable and accrued liabilities (48.3) Deferred tax liabilities, net (348.1) Other liabilities (118.0) Total liabilities (615.5) Net assets acquired $ 3,542.0 The Company has performed a preliminary valuation analysis of the fair market value of assets and liabilities of the Bureau van Dijk business. The final purchase price allocation will be determined when the Company has completed and fully reviewed the detailed valuations. The final allocation could differ materially from the preliminary allocation. The final allocation may include changes in allocations to acquired intangible assets as well as goodwill and other changes to assets and liabilities includi ng reser ves for uncertain tax positions and deferred tax liabilities. The estimated useful lives of acquired intangibles assets are also preliminary. Current assets in the table above include acquired cash of $ 3 6 million. Additionally, current assets incl ude accounts receivable of approximately $9 0 million (net of an allowance for uncollectible accounts of $1.4 million) . The amount of Bureau van Dijk's revenue and N et Income from August 10, 2017 through September 30, 2017 included in the Company's statement of operatio ns was $ 30.3 million and ( $ 2.0) million, respectively. The acquired deferred revenue balance was reduced by $53 million as part of acquisition accounting to establish the fair value of deferred revenue. This will reduce reported revenue by $53 million ov er the remaining contractual period of in progress customer arrangements assumed as of the acquisition date. This resulted in an approximate $14 million reduction in reported revenue for the period from August 10, 2017 to September 30, 2017. Amortization of acquired in tangible assets was approximately $10 million for the period from August 10, 2017 through September 30, 2017. Goodwill Under the acquisition method of accounting for business combinations, the excess of the purchase price over the fair value of the net assets acquired is allocated 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 qual ify for separate recognition. The goodwill recognized as a result of this acquisition includes, among other things, the value of combining the complementary product portfolios of the Company and Bureau van Dijk which is expected to extend the Company’s rea ch to new and evolving market segments as well as cost savings synergies, expected new customer acquisitions and products. Goodwill, which has been assigned to the MA segment, is not deductible for tax purposes. Bureau van Dijk will be a separate reporti ng unit for purposes of the Company’s annual goodwill impairment assessment. Other Liabilities Assumed In connection with the acquisition, the Company assumed liabilities relating to UTBs as well as deferred tax liabilities which relate to acquired intangible assets. These items are included in other liabilities in the table above. Transaction and Non-Recurring Integration Costs. In connection with the acquisition, the Company incurred transaction and non-recurring integration costs (Acquisition-Rel ated Expenses) through the first nine months of 2017. Acquisition-Related Expenses of $16.7 million were comprised of transaction costs (consisting primarily of legal and advisory costs) of $8.5 million and non-recurring integration costs of $ 8.2 million f or the nine months ended September 30, 2017. Supplementary Unaudited Pro Forma Information Supplemental information on an unaudited pro forma basis is presented below for the nine months ended September 30, 2017 and 2016 as if the acquisition of Bureau van Dijk occurred on January 1, 2016. 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 o perations or the results that would have been reported if the acquisition had been completed at January 1, 2016. The unaudited pro forma information includes amortization of acquired intangible assets , based on the preliminary 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 r elates. (Amounts in millions) For the nine months ended September 30, 2017 For the nine months ended September 30, 2016 Proforma Revenue $ 3,226.9 $ 2,821.8 Proforma Net Income attributable to Moody's $ 965.9 $ 695.1 The unaudited pro forma results do not include any anticipated cost savings or other effects of the planned integration of Bureau van Dijk . 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 Bureau van Dijk results included in the above have been converted to U.S. GAAP from IFRS as issued by t he IASB and have been translated to USD at rates in effect for the periods presented. The Bureau van Dijk amounts in the pro forma results include a reduction in revenue of approximately $50 million and $1 million relating to a fair value adjustment to de ferred revenue required as part of acquisition accounting for the nine months ended September 30, 2016 and 2017, respectively. The following acquisitions occurred prior to the third quarter 2017. The Company has not presented proforma combined results for these acquisitions because the impact on previously reported statements of operations would not have been material. Additionally, the near term impact to the Company’s operations and cash flows is not material. SCDM Financial On February 13, 2017, a subsidiary of the Company acquired the structured finance data and analytics business of SCDM Financial. The aggregate pu rchase price was not material and the near term impact to the Company’s operations and cash flow is not expected to be material. This business unit operates in the MA reportable segment and goodwill related to this acquisition has been allocated to the RD& A reporting unit. Korea Investor Service (KIS) In July 2016, a subsidiary of the Company acquired the non-controlling interest of KIS and additional shares of KIS Pricing. The aggregate purchase price was not material and the near term impact to the Compa ny’s operations and cash flow is not expected to be material. KIS and KIS Pricing are a part of the MIS segment. Gilliland Gold Young (GGY) On March 1, 2016, subsidiaries of the Company acquired 100 % of GGY, a leading provider of advan ced actuarial software for the life insurance industry. The cash payments noted in the table below were funded with cash on hand. The acquisition of GGY will allow MA to provide an industry-leading enterprise risk offering for global life insurers and reinsurers.

DERIVATIVE INSTRUMENTS AND HEDG

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	9 Months Ended
	Sep. 30, 2017
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	NOTE 7 . 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: Interest Rate Swaps The Com pany has entered into interest rate swaps to convert the fixed interest rate on certain of its long-term debt to a floating interest rate ba sed on the 3-month LIBOR. The purpose of these hedges is to mitigate the risk associated with changes in the fair va lue 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) income, net in the Company’s consolidated statement of operations. The following table summarizes the Company’s intere st rate swaps designated as fair value hedges: Hedged Item Nature of Swap Notional Amount Floating Interest Rate As of September 30, 2017 As of December 31, 2016 2010 Senior Notes due 2020 Pay Floating/Receive Fixed $ 500.0 $ 500.0 3-month LIBOR 2014 Senior Notes due 2019 Pay Floating/Receive Fixed $ 450.0 $ 450.0 3-month LIBOR 2012 Senior Notes due 2022 Pay Floating/Receive Fixed $ 80.0 $ 80.0 3-month LIBOR The following table summarizes the impact to the statement of operations of the Company’s interest rate swaps designated as fair value hedges : Amount of income recognized in the consolidated statements of operations Three Months Ended Nine months ended September 30, September 30, Derivatives designated as fair value accounting hedges Location on Statement of Operations 2017 2016 2017 2016 Interest rate swaps Interest expense, net $ 1.6 $ 2.7 $ 5.8 $ 8.8 Cross-currency swaps In conjunction with the issuance of the 2015 Senior Notes, the Company entered into a cross-currency swap to exchange € 100 million for U.S. dollars on the date of the settlement of the notes. The purpose of this cross-currency swap is to mitigate FX risk on the remaining principal balance on the 2015 Senior Notes that was not designated as a net investment hedge as more fully discussed below. Under the terms of the swap, the Company will pay the counterparty interest on the $ 110.5 mill ion received at 3.945 % per annum and the counterparty will pay the Company interest on the €100 million paid at 1.75 % per annum. These interest payments will be settled in March of each year, beginning in 2016, until either the maturity of the cross-curren cy swap in 2027 or upon early termination at the discretion of the Company. The principal payments on this cross currency swap will be settled in 2027, concurrent with the repayment of the 2015 Senior Notes at maturity or upon early termination at the disc retion of the Company. In March 2016, the Company designated these cross-currency swaps as cash flow hedges. Accordingly, changes in fair value subsequent to the date the swaps were designated as cash flow hedges will initially be recognized in OCI. Gains and losses on the swaps initially recognized in OCI will be reclassified to the statement of operations in the period in which changes in the underlying hedged item affects net income. Ineffectiveness, if any, will be recognized in other non-operating (exp ense) income, net in the Company’s consolidated statement of operations. Forward start interest rate swaps In the second quarter of 2017, i n con junction with the then-forecasted issuance of the Company’s 2017 Private Placement Notes Due 2023 and 2017 Priv ate Placement Notes Due 202 8, the Company entered into forward starting interest rate swap s to mitigate the risk of changes in the semi-annual interest payments attributable to changes in market interest rates during the period leading up to the forecasted debt issuance. The swaps were terminated on June 5, 2017 following the issuance of the aforementioned notes and the losses recorded to OCI upon settlement were not material. Net investment hedges The Company entered into foreign currency forward contracts that are designated as net investment hedges and additionally has designated € 400 million of the 2015 Senior Notes D ue 2027 as a net investment hedge. These hedges are intended to mitigate FX exposure related to non-U.S. dol lar net investments in certain foreign subsidiaries against changes in foreign exchange rates. These net investment hedges are designated as accounting hedges under the applicable sections of Topic 815 of the ASC. This net investment hedge will end upon th e repayment of the notes in 2027 unless terminated earlier at the discretion of the Company. Hedge effectiveness is assessed based on the overall changes in the fair value of the hedge. For hedges that meet the effectiveness requirements, any change in th e fair value is recorded in OCI in the foreign currency translation account.

CCXI Gain: CCXI is a Chinese credit rating agency in which Moody’s acquired a 49 % stake in 2006. Moody’s accounts for this investment under the equity method of accounting. On March 21, 2017, CCXI, as part of a strategic business realignment, issued additional capital to its majority shareholder in exchange for a ratings business wholly-owned by the majority shareholder and which has the right to rate a different class of debt instrument in the Chinese market. The capital issuance by CCXI in exchange for this ratings business diluted Moody’s ownership interest in CCXI to 30 % of a larger business and resulted in a $ 59.7 million non-cash, non-taxable gain. The issuance of additional capital by CCXI is treated as if Moody’s sold a 19% interest in CCXI at fair value. The fair value of the 19 % interest in CCXI that Moody’s hypothetically sold was estimated using both a discounted cash flow methodology and comparable public company multiples. A DCF analysis requires significant estimates, including projection s of future operating results and cash flows based on the budgets and forecasts of CCXI, expected long-term growth rates, terminal values, WACC and the effects of external factors and market conditions. Moody’s will continue to account for its 30% interest in CCXI under the equity method of accounting.

The U.S. plans provide defined benefits using a cash balance formula based on years of service and career average salary for its employees 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 noncontribu tory. 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”.

CONTINGENCIES

CONTINGENCIES	NOTE 15 . CONTINGENCIES Given the nature of their activities, Moody’s and its subsidiaries are subject to legal and tax proceedings, governmental, regulatory and legislative investigations and inquiries, and claims and litigation that are based on ratings assigned by MIS or that are otherwise incidental to the Company’s business. The Company periodically receives and responds to subpoenas and other inquiries which may relate to Moody’s activities or to activities of others that may result in claims and litigation, proceedings or in vestigations by private litigants or governmental, regulatory or legislative authorities. Moody’s also is subject to ongoing tax audits as addressed in Note 4 to the financial statements. Management periodically assesses the Company’s liabilities and cont ingencies 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 fi nancial 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 mini mum 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 a nd/or the amou nt 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 materi al 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 investi gations 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 canno t 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 compet itive 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 oc cur, the ultimate outcome of such matters, including the amount of any loss, may differ from those estimates.

SEGMENT INFORMATION

SEGMENT INFORMATION	9 Months Ended
	Sep. 30, 2017
SEGMENT INFORMATION	NOTE 16 . 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 the distribution of research and financ ial instruments pricing services in the Asia-Pacific region as well as ICRA non-ratings revenue. The MA segment develops a wide range of products and services that support the risk management activities of institutional participants in global financial mar kets. The MA segment consists of three LOBs - RD&A, ERS and PS. On August 10 , 2017, a subsidiary of the C ompany acquired Yellow Maple I B.V., an indirect parent of Bureau van Dijk, a global provider of business intelligence and company information products . Bureau van Dijk is part of the MA reportable segment and its revenue is included in the RD&A LOB. Refer to Note 7 for further discussion on the acquisition . Revenue for MIS and expenses for MA include an intersegment royalty charged to MA for the right s to use and distribute content, data and products developed by MIS. The royalty rate charged by MIS approximates the fair value of the aforementioned content, data and products and is generally based on comparable market transactions. Also, 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 fees charged by MA are generally equal to the costs incurred by MA to produce these products and services . Additionally, overhead costs and corporate expenses of the Company that exclusively benefit only one segment are fully charged to that segment. Overhead costs and corporate expenses of the Company that benefit both segments are allocated to each segment based on a revenue-split methodology. Accordingly, a reportable segment’s share of these costs will increase as its proportion of revenue relative to Moody’s total revenue increases. Overhead expenses include costs such as rent and occupancy, information t echnology and support staff such as finance, human resources and information technology. “Eliminations” in the table below represent intersegment revenue/expense. Moody’s does not report the Company’s assets by reportable segment, as this metric is not use d 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, Adjusted Operating Income and operating i ncome 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.

RECENTLY ISSUED ACCOUNTING STAN

RECENTLY ISSUED ACCOUNTING STANDARDS	9 Months Ended
	Sep. 30, 2017
RECENTLY ISSUED ACCOUNTING STANDARDS	NOTE 17 . RECENTLY ISSUED ACCOUNTING STANDARDS In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”. This ASU outlines a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14 “Revenue from Contracts with Customers (Topic 606), Deferral of the Effective Date” which defers the effective date of the ASU for annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted up to the original effective date of December 15, 2016. In addition, during 2016, the FASB issued additional upd ates clarifying the implementation guidance for the new revenue recognition standard. The Company intends to adopt the new revenue guidance as of January 1, 2018 using the modified retrospective transition method. Under this adoption method, the Company w ill record a cumulative adjustment to retained earnings at January 1, 2018 and apply the provisions of the ASU prospectively. Currently, the Company believes this ASU will have an impact on, which is not limited to: i) the accounting for certain software s ubscription revenue in MA whereby the license rights within the arrangement would be recognized at the inception of the contract based on estimated stand-alone selling price with the remainder recognized over the subscription period (compared to ASC 605 wh ereby all software subscription revenue is currently recognized over the subscription period); ii) the accounting for certain ERS and ESA revenue arrangements where VSOE is not currently available under ASC 605 would result in the acceleration of revenue r ecognition (compared to ASC 605 whereby revenue is currently deferred due to lack of VSOE); iii) the capitalization and related period of expense recognition for sales commissions, which are incurred in the MA segment; iv) the capitalization of s oftware implementation project costs to fulfill a contract for its ERS and ESA businesses which will be expensed as incurred under the new standard; and v) the capitalization of work in process costs for in-progress MIS ratings at the end of each reporting period. This ASU will also require new comprehensive disclosures about contracts with customers including the significant reasonable judgments the Company has made when applying the ASU. At September 30, 2017, the Company continues to assess and docume nt key changes to its accounting policies relating to the adoption of the new revenue accounting standard. Additionally, the Company is assessing the impact that the standard will have on its processes and controls. Furthermore, the Company is in the proc ess of implementing software in order to support the accounting under the new standard as well as assessing the impact that the new standard for MA multi-element arrangements, which primarily occur within the ERS and ESA revenue streams. In January 2016, the FASB issued ASU No. 2016-01 “Financial Instruments – Overall (Subtopic 825-10), Recognition and Measurement of Financial Assets and Financial Liabilities”. The amendments in this ASU update various aspects of recognition, measurement, presentation and disclosures relating to financial instruments. This ASU is effective for fiscal years beginning after December 15, 2017. The Company is currently evaluating the impact of this ASU on the Company’s financial statements. The Company believes that the most p ertinent impact to its financial statements upon the adoption of this ASU will relate to the discontinuance of the available-for-sale classification for investments in equity securities (unrealized gains and losses were recorded through OCI). Accordingly, subsequent to adoption of this ASU, changes in the fair value of equity securities held by the Company will be recorded through earnings. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” requiring lessees to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses and cash flows will depend on classification as either a finance or operating lease. This ASU is effective for fiscal years b eginning after December 15, 2018, with early adoption permitted. This standard must be adopted using a modified retrospective approach whereby leases will be presented in accordance with the new standard as of the earliest period presented. The Company is currently evaluating the impact of this ASU on the Company’s financial statements. The Company believes that the most notable impact to its financial statements upon the adoption of this ASU will be the recognition of a material right-of-use asset and leas e liability for its real estate leases. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments”. The amendments in this ASU require the use of an “expected c redit loss” impairment model for most financial assets reported at amortized cost which will require entities to estimate expected credit losses over the lifetime of the instrument. This may result in the earlier recognition of allowances for losses. For a vailable-for-sale debt securities with unrealized losses, an allowance for credit losses will be recognized as a contra account to the amortized cost carrying value of the asset rather than a direct reduction to the carrying value, with changes in the allo wance impacting earnings. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019, with early adoption permitted in annual and interim reporting periods beginning after December 15, 2018. Entities will apply the sta ndard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first effective reporting period. The Company is currently evaluating the impact of this ASU on its financial statements. Currently, the Company believes t hat the most notable impact of this ASU will relate to its processes around the assessment of the adequacy of its allowance for doubtful accounts on accounts receivable. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230) , Classification of Certain Cash Receipts and Cash Payments”. This ASU adds or clarifies guidance on the classification of certain cash receipts and payments in the statement of cash flows with the intent to alleviate diversity in practice for classifying various types of cash flows. This ASU is effective for annual and interim reporting periods beginning after December 15, 2017, with early adoption permitted. The Company will apply this clarification guidance in its statements of cash flows upon adoption. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805), Clarifying the Definition of a Business”. This ASU clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whethe r transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This ASU is effective for annual and interim reporting periods beginning after December 15, 2017 and should be applied prospectively. Upon adoption, the Company will apply the guidance in this ASU when evaluating whether acquired assets and activities constitute a business. In March 2017, the FASB issued ASU No. 2017-07, “Compensation – Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic P ension Cost and Net Periodic Postretirement Benefit Cost”. This ASU impacts the presentation of net periodic pension costs in the statement of operations. Entities will be required to report the service cost component in the same line item or items as othe r compensation costs (either Operating or SG&A in Moody’s statement of operations). The other components of net benefit cost are required to be presented in the statement of operations separately from the service cost component and outside of operating inc ome. The ASU permits only the service cost component of net periodic pension cost to be eligible for capitalization, when applicable. This ASU is effective for annual and interim reporting periods beginning after December 15, 2017. Upon adoption, the Compa ny will bifurcate its net periodic pension costs reported in its statements of operations in accordance with this ASU. In May 2017, the FASB issued ASU No. 2017-09, “ Compensation—Stock Compensation (Topic 718) , Scope of Modification Accounting ” . This ASU c larifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. Under this ASU, an entity will not apply modification accounting to a share-based payment award if the award’s fair value, vesting condi tions and classification as an equity or liability instrument are the same immediately before and after the change. The new guidance will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications . This ASU is effective for annual and interim reporting periods beginning after December 15, 2017 and should be applied prospectively to awards modified on or after the adoption date. The Company does not expect the adoption of this ASU to have a material impact on its financial statements . In July 2017, the FASB issued ASU No. 2017-12, “ Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities ”. This ASU enables entitie s to enhance transparency relating to risk management activities and simplifies the application of hedge accounting in certain circumstances. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those years with early adoption permitted. The Company is currently in the process of assessing the impact that this ASU will have on its financial statements.
