The Company also granted 0.9 million shares of restricted stock in the first nine months of 2014, which had a weighted average grant date fair value of $79.62 per share and generally vest ratably 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 metrics of the Company over a three-year period. The weighted average grant date fair value of these awards was $76.35 per share.
	The following weighted average assumptions were used in determining the fair value for options granted in 2014:
	Expected dividend yield	1.41%
	Expected stock volatility	41.20%
	Risk-free interest rate	2.30%
	Expected holding period	7.2 years
	Grant date fair value	$31.53
	Unrecognized compensation expense at September 30, 2014 was $9.9 million and $96.2 million for stock options and unvested restricted stock, respectively, which is expected to be recognized over a weighted average period of 1.3 years and 1.7 years, respectively. Additionally, there was $17.8 million of unrecognized compensation expense relating to the aforementioned non-market based performance-based awards, which is expected to be recognized over a weighted average period of 1.0 years.

INCOME TAXES	'
	NOTE 3. INCOME TAXES
	Moody’s effective tax rate was 33.5% and 29.1% for the three months ended September 30, 2014 and 2013, respectively. The increase in the ETR compared to the third quarter of 2013 is primarily due to higher U.S. and non-U.S. taxes on foreign income in 2014 and certain discrete items that reduced the ETR in 2013.
	Moody’s ETR was 32.0% and 30.1% for the nine month periods ended September 30, 2014 and 2013, respectively. The increase over the prior year is primarily due to higher U.S. and non-U.S. taxes on foreign income. The nine months ended September 30, 2013 ETR included a tax benefit related to U.S. tax legislation enacted in early 2013 which retroactively extended certain tax benefits to the 2012 tax year, as well as tax benefits on a litigation settlement in the first quarter of 2013. The ETR for the nine month period ended September 30, 2014 includes a benefit related to the reversal of UTPs resulting from the favorable resolution of certain international tax matters.
	The Company classifies interest related to UTPs in interest expense, net in its consolidated statements of operations. Penalties, if incurred, would be recognized in other non-operating (expense) income, net. The Company had an increase in its UTPs of $7.1 million ($4.0 million net of federal tax benefit) during the third quarter of 2014 and an overall increase in its UTPs during the first nine months of 2014 of $16.0 million ($8.4 million net of federal tax benefits).
	Moody’s Corporation and subsidiaries are subject to U.S. federal income tax as well as income tax in various states, local and foreign jurisdictions. The Company’s U.S. federal income tax returns for the years 2008 through 2010 are under examination and its returns for 2011 through 2013 remain open to examination. The Company’s New York State tax returns for 2011 and 2012 remain open to examination. Income tax filings in the U.K. for 2012 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 audits, which might involve the payment of additional taxes, the adjustment of certain deferred taxes and/or the recognition of tax benefits. It is also possible that new issues might be raised by tax authorities which could necessitate increases to the balance 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 financial exposure relating to all open tax years by tax jurisdiction in accordance with the applicable provisions of Topic 740 of the ASC regarding UTBs.
	The following table shows the amount the Company paid for income taxes:
		Nine Months Ended

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	'
	NOTE 6. 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.
	Interest Rate Swaps
	In the fourth quarter of 2010, the Company entered into interest rate swaps with a total notional amount of $300 million to convert the fixed interest rate on the Series 2005-1 Notes to a floating interest rate based on the 3-month LIBOR. The purpose of this hedge was to mitigate the risk associated with changes in the fair value of the Series 2005-1 Notes, thus the Company has designated these swaps as fair value hedges. The fair value of the swaps was adjusted quarterly with a corresponding adjustment to the carrying value of the Series 2005-1 Notes. The changes in the fair value of the hedges and the underlying hedged item generally offset and the net cash settlements on the swaps were recorded each period within interest income (expense), net, in the Company’s consolidated statement of operations. In August of 2014, the Company terminated the swaps on the Series 2005-1 Notes concurrent with the early retirement of those notes as further described in Note 13. The termination of these swaps resulted in a gain of approximately $4 million in the third quarter of 2014 which is recorded in interest income (expense), net in the Company’s condensed consolidated financial statements.
	In the second quarter of 2014, the Company entered into interest rate swaps with a total notional amount of $250 million to convert the fixed interest rate on the 2010 Senior Notes to a floating interest rate based on the 3-month LIBOR. In the third quarter of 2014, the Company entered into interest rate swaps with a total notional amount of $250 million to convert the fixed interest rate on the remaining balance of the 2010 Senior Notes to a floating interest rate based on the 3-month LIBOR. The purpose of these hedges is to mitigate the risk associated with changes in the fair value of the 2010 Senior Notes, 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 2010 Senior Notes. The changes in the fair value of the hedges and the underlying hedged item generally offset and the net cash settlements on the swaps are recorded each period within interest income (expense), net, in the Company’s consolidated statement of operations.
	In the third quarter of 2014, the Company entered into interest rate swaps with a total notional amount of $250 million to convert the fixed interest rate on a portion of the 2014 Senior Notes (5-year) to a floating interest rate based on the 3-month LIBOR. The purpose of this hedge was to mitigate the risk associated with changes in the fair value of a portion of the 2014 Senior Notes (5-year), 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 2014 Senior Notes (5-year). The changes in the fair value of the hedges and the underlying hedged item generally offset and the net cash settlements on the swaps are recorded each period within interest income (expense), net, in the Company’s consolidated statement of operations.
	Foreign Exchange Forwards
	The Company also enters into foreign exchange forwards to mitigate the change in fair value on certain assets and liabilities denominated in currencies other than a subsidiary’s functional currency. These forward contracts are not designated as accounting hedges under the applicable sections of Topic 815 of the ASC. Accordingly, changes in the fair value of these contracts are recognized immediately in other non-operating (expense) income, net in the Company’s consolidated statements of operations along with the FX gain or loss recognized on the assets and liabilities denominated in a currency other than the subsidiary’s functional currency. These contracts have expiration dates at various times through February 2015.

	Net Investment Hedges
	The Company enters into foreign currency forward contracts to hedge the exposure related to non-U.S. dollar net investments in certain foreign subsidiaries against adverse changes in foreign exchange rates. These forward contracts are designated as accounting hedges under the applicable sections of Topic 815 of the ASC. Hedge effectiveness is assessed based on the overall changes in the fair value of the forward contracts on a pre-tax basis. For hedges that meet the effectiveness requirements, any change in the fair value for the hedge is recorded in the currency translation adjustment component of AOCI. Any change in the fair value of these hedges that is the result of ineffectiveness would be recognized immediately in other non-operating (expense) income in the Company’s consolidated statement of operations. These outstanding contracts expire in December 2014 for contracts to sell euros for USD and in November 2014 for contracts to sell Japanese yen for USD.

	Foreign currency translation adjustments					-0.2			-0.1
	Balance as of September 30				$	13.3		$	12.4
	The losses included in earnings in the table above are recorded within SG&A expenses in the Company’s consolidated statements of operations and relate to contingent consideration obligations outstanding at September 30, 2014.
	Of the $13.3 million of contingent consideration obligations as of September 30, 2014, $11.1 million is classified in accounts payable and accrued liabilities and $2.2 million is classified in other liabilities within the Company’s consolidated balance sheet.
	The following are descriptions of the methodologies utilized by the Company to estimate the fair value of its derivative contracts, fixed maturity plans and contingent consideration obligations:
	Derivatives:
	In determining the fair value of the derivative contracts, the Company utilizes industry standard valuation models. Where applicable, these models project future cash flows and discount the future amounts to a present value using spot rates, forward points, currency volatilities, interest rates as well as the risk of non-performance of the Company and the counterparties with whom it has derivative contracts. The Company established strict counterparty credit guidelines and only enters into transactions with financial institutions that adhere to these guidelines. Accordingly, the risk of counterparty default is deemed to be minimal.
	Fixed maturity and open ended mutual funds:
	The fixed maturity mutual funds and open ended mutual funds primarily represent exchange traded funds in India held by ICRA and are classified as securities available-for-sale. Accordingly, any unrealized gains and losses in future quarters will be recognized through OCI until the instruments mature. The cost basis of these investments is $41.2 million at September 30, 2014.
	Contingent consideration:
	At September 30, 2014, the Company has contingent consideration obligations related to the acquisitions of CSI and Copal which are carried at estimated fair value, and are based on certain financial and non-financial metrics set forth in the acquisition agreements. These obligations are measured using Level 3 inputs as defined in the ASC. The Company recorded the obligations for these contingent consideration arrangements on the date of each respective acquisition based on management’s best estimates of the achievement of the metrics and the value of the obligations are adjusted quarterly.
	The contingent consideration obligation for CSI is based on the achievement of a certain contractual milestone by January 2016. The Company utilizes a discounted cash flow methodology to value this obligation. The future expected cash flow for this obligation is discounted using an interest rate available to borrowers with similar credit risk profiles to that of the Company. The most significant unobservable input involved in the measurement of this obligation is the probability that the milestone will be reached by January 2016. At September 30, 2014, the Company expects that this milestone will be reached by the aforementioned date.
	There are several contingent consideration obligations relating to the acquisition of Copal. A portion of the contingent cash payments are based on revenue and EBITDA growth for certain of the Copal entities. This growth is calculated by comparing revenue and EBITDA in the year immediately prior to the exercise of the put/call option to acquire the remaining 33% ownership interest of Copal Partners Limited which the Company does not currently own, to revenue and EBITDA in Copal’s fiscal year ended March 31, 2011. There are no limitations set forth in the acquisition agreement relating to the amount payable under this contingent consideration arrangement. Payments under this arrangement, if any, would be made upon the exercise of the aforementioned put/call option, which expires in November 2017. The Company utilizes discounted cash flow methodologies to value these obligations. The expected future cash flows for these obligations are discounted using a risk-free interest rate plus a credit spread based on the option adjusted spread of the Company’s publicly traded debt as of the valuation date plus sovereign and size risk premiums. The most significant unobservable input involved in the measurement of these obligations is the projected future financial results of the applicable Copal entities. These remaining obligations will be settled upon closing of Moody’s exercise of its call option which is expected to occur in the fourth quarter of 2014 as discussed in Note 10. The payment is expected to be approximately $11 million. Other contingent cash payments were based on the achievement of revenue targets for Copal’s fiscal year ended March 31, 2013 and a $2.5 million payment was made in 2013.
	For the contingent consideration obligations relating to the acquisition of Amba, the payment was based on the acquired entity achieving a revenue target for its fiscal year ended March 31, 2014 which was met resulting in a $4.3 million payment in 2014.
	A significant increase or decrease in any of the aforementioned significant unobservable inputs related to the fair value measurement of the Company’s contingent consideration obligations would result in a significantly higher or lower reported fair value for these obligations.

	Redeemable Noncontrolling Interest:
	In connection with the acquisition of Copal, the Company and the non-controlling shareholders entered into a put/call option agreement whereby the Company has the option to purchase from the non-controlling shareholders and the non-controlling shareholders have the option to sell to the Company the remaining 33% ownership interest of Copal Partners Limited based on a strike price to be calculated on pre-determined formulas using a combination of revenue and EBITDA multiples when exercised. The value of the estimated put/call option strike price on the date of acquisition was based on a Monte Carlo simulation model. This model contemplated multiple scenarios which simulated certain of Copal’s revenue, EBITDA margins and equity values to estimate the present value of the expected strike price of the option. In connection with the acquisition of Amba in December 2013, which was combined with Copal to form the Copal Amba reporting unit, the aforementioned revenue and EBITDA multiples set forth in the put/call option were modified to include the results of Amba. The option is subject to a minimum exercise price of $46 million. There is no limit as to the maximum amount of the strike price on the put/call option.
	In the third quarter of 2014, the Company notified the non-controlling shareholders that it planned to exercise its call option to acquire the remaining interest of Copal Amba that it does not currently own which is expected to close in the fourth quarter of 2014. In accordance with certain agreements relating to the acquisition of Copal Amba, the Company will incur a 25% premium to the formulaic redemption value of the non-controlling interest.
	The following table shows changes in the redeemable noncontrolling interest related to the acquisition of Copal:

	The fair value of the Company’s long-term debt is estimated using discounted cash flows with inputs based on prevailing interest rates available to the Company for borrowings with similar maturities.
	The Company has the capacity to borrow up to $1 billion under its unsecured revolving credit facility which expires in April 2017. Any future borrowings under this facility would accrue interest at LIBOR plus a premium that can range from 77.5 bps to 120 bps per annum based on the Company’s debt/EBITDA ratio.
	On August 7, 2014, the Company prepaid the Series 2005-1 Notes using proceeds from the issuance of the 2014 Senior Notes (30-year) and the 2014 Senior Notes (5-year), which are discussed below.
	On July 16, 2014, the Company issued $300 million aggregate principal amount of senior unsecured notes in a public offering. The 2014 Senior Notes (30-year) bear interest at a fixed rate of 5.250% and mature on July 15, 2044. Interest on the 2014 Senior Notes (30-year) will be due semi-annually on January 15 and July 15 of each year, commencing January 15, 2015. The Company may prepay the 2014 Senior Notes (30-year), in whole or in part, at any time at a price equal to 100% of the principal amount being prepaid, plus accrued and unpaid interest and a Make-Whole Amount. Additionally, at the option of the holders of the notes, the Company may be required to purchase all or a portion of the notes upon occurrence of a “Change of Control Triggering Event,” as defined in the 2014 Indenture, at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase. The 2014 Indenture contains covenants that limit the ability of the Company and certain of its subsidiaries to, among other things, incur or create liens and enter into sale and leaseback transactions. In addition, the 2014 Indenture contains a covenant that limits the ability of the Company to consolidate or merge with another entity or to sell all or substantially all of its assets to another entity. The 2014 Indenture contains customary default provisions. In addition, an event of default will occur if the Company or certain of its subsidiaries fail to pay the principal of any indebtedness (as defined in the 2014 Indenture) when due at maturity in an aggregate amount of $50 million or more, or a default occurs that results in the acceleration of the maturity of the Company’s or certain of its subsidiaries’ indebtedness in an aggregate amount of $50 million or more. Upon the occurrence and during the continuation of an event of default under the 2014 Indenture, the 2014 Senior Notes (30-year) may become immediately due and payable either automatically or by the vote of the holders of more than 25% of the aggregate principal amount of all of the notes then outstanding.
	On July 16, 2014, the Company issued $450 million aggregate principal amount of senior unsecured notes in a public offering. The 2014 Senior Notes (5-year) bear interest at a fixed rate of 2.750% and mature July 15, 2019. Interest on the 2014 Senior Notes (5-year) will be due semi-annually on January 15 and July 15 of each year, commencing January 15, 2015. The Company may prepay the 2014 Senior Notes (5-year), in whole or in part, at any time at a price prior to June 15, 2019, equal to 100% of the principal amount being prepaid, plus accrued and unpaid interest and a Make-Whole Amount. Notwithstanding the immediately preceding sentence, the Company may redeem the 2014 Senior Notes (5-year), in whole or in part, at any time or from time to time on or after June 15, 2019 (one month prior to their maturity), at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding the redemption date. Additionally, at the option of the holders of the notes, the Company may be required to purchase all or a portion of the notes upon occurrence of a “Change of Control Triggering Event,” as defined in the 2014 Indenture, at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase. The 2014 Indenture contains covenants that limit the ability of the Company and certain of its subsidiaries to, among other things, incur or create liens and enter into sale and leaseback transactions. In addition, the 2014 Indenture contains a covenant that limits the ability of the Company to consolidate or merge with another entity or to sell all or substantially all of its assets to another entity. The 2014 Indenture contains customary default provisions. In addition, an event of default will occur if the Company or certain of its subsidiaries fail to pay the principal of any indebtedness (as defined in the 2014 Indenture) when due at maturity in an aggregate amount of $50 million or more, or a default occurs that results in the acceleration of the maturity of the Company’s or certain of its subsidiaries’ indebtedness in an aggregate amount of $50 million or more. Upon the occurrence and during the continuation of an event of default under the 2014 Indenture, the 2014 Senior Notes (5-year) may become immediately due and payable either automatically or by the vote of the holders of more than 25% of the aggregate principal amount of all of the notes then outstanding.
	The proceeds from both notes issued on July 16, 2014 were used for the aforementioned prepayment of the Series 2005-1 Notes and will also be used for general corporate purposes.

CONTINGENCIES	'
	From time to time, Moody’s is involved in legal and tax proceedings, governmental 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.
	Following the global credit crisis of 2008, MIS and other credit rating agencies have been the subject of intense scrutiny, increased regulation, ongoing inquiry and governmental investigations, and civil litigation. Legislative, regulatory and enforcement entities around the world are considering additional legislation, regulation and enforcement actions, including with respect to MIS’s compliance with regulatory standards. Moody’s has received subpoenas and inquiries from states attorneys general and other domestic and foreign governmental authorities and is responding to such investigations and inquiries.
	In addition, the Company is facing litigation from market participants relating to the performance of MIS rated securities. Although Moody’s in the normal course experiences such litigation, the volume and cost of defending such litigation has significantly increased following the events in the U.S. subprime residential mortgage sector and global credit markets more broadly over the last several years.
	On August 25, 2008, Abu Dhabi Commercial Bank filed a purported class action in the United States District Court for the Southern District of New York asserting numerous common-law causes of action against two subsidiaries of the Company, another rating agency, and Morgan Stanley & Co. The action related to securities issued by a structured investment vehicle called Cheyne Finance (the “Cheyne SIV”) and sought, among other things, compensatory and punitive damages. The central allegation against the rating agency defendants was that the credit ratings assigned to the securities issued by the Cheyne SIV were false and misleading. In early proceedings, the court dismissed all claims against the rating agency defendants except those for fraud and aiding and abetting fraud. In June 2010, the court denied plaintiff’s motion for class certification, and additional plaintiffs were subsequently added to the complaint. In January 2012, the rating agency defendants moved for summary judgment with respect to the fraud and aiding and abetting fraud claims. Also in January 2012, in light of new New York state case law, the court permitted the plaintiffs to file an amended complaint that reasserted previously dismissed claims against all defendants for breach of fiduciary duty, negligence, negligent misrepresentation, and related aiding and abetting claims. In May 2012, the court, ruling on the rating agency defendants’ motion to dismiss, dismissed all of the reasserted claims except for the negligent misrepresentation claim, and on September 19, 2012, after further proceedings, the court also dismissed the negligent misrepresentation claim. On August 17, 2012, the court ruled on the rating agencies’ motion for summary judgment on the plaintiffs’ remaining claims for fraud and aiding and abetting fraud. The court dismissed, in whole or in part, the fraud claims of four plaintiffs as against Moody’s but allowed the fraud claims to proceed with respect to certain claims of one of those plaintiffs and the claims of the remaining 11 plaintiffs. The court also dismissed all claims against Moody’s for aiding and abetting fraud. Three of the plaintiffs whose claims were dismissed filed motions for reconsideration, and on November 7, 2012, the court granted two of these motions, reinstating the claims of two plaintiffs that were previously dismissed. On February 1, 2013, the court dismissed the claims of one additional plaintiff on jurisdictional grounds. Trial on the remaining fraud claims against the rating agencies, and on claims against Morgan Stanley for aiding and abetting fraud and for negligent misrepresentation, was scheduled for May 2013. On April 24, 2013, pursuant to confidential settlement agreements, the 14 plaintiffs with claims that had been ordered to trial stipulated to the voluntary dismissal, with prejudice, of these claims as against all defendants, and the Court so ordered that stipulation on April 26, 2013. The settlement did not cover certain claims of two plaintiffs that were previously dismissed by the Court. On May 23, 2013, these two plaintiffs filed a Notice of Appeal to the Second Circuit, seeking reversal of the dismissal of their claims and also seeking reversal of the Court’s denial of class certification. According to pleadings filed by plaintiffs in earlier proceedings, they seek approximately $76 million in total compensatory damages in connection with the two claims at issue on the appeal.
	On July 9, 2009, the California Public Employees’ Retirement System (“CalPERS”) filed an action in the Superior Court of California in San Francisco (the “Superior Court”) asserting two common-law causes of action, negligent misrepresentation and negligent interference with prospective economic advantage. The complaint named as defendants the Company, one of the Company’s subsidiaries (Moody’s Investors Service, Inc.), The McGraw-Hill Companies, Fitch, Inc., and various subsidiaries of Fitch, Inc. (CalPERS subsequently released the Fitch entities from the case). The action relates to the plaintiff’s purchase of securities issued by three structured investment vehicles (“SIVs”), known as Cheyne, Sigma, and Stanfield Victoria. The plaintiff’s complaint seeks unspecified compensatory damages arising from alleged losses in connection with investments that purportedly totaled approximately $1.3 billion; in subsequent court filings, the plaintiff claimed to have suffered “unrealized losses” of approximately $779 million. The central allegation against the defendants is that the credit ratings assigned to the securities issued by the SIVs were inaccurate and that the methodologies used by the rating agencies had no reasonable basis. In August 2009, the defendants removed the action to federal court, but the case was remanded to state court in November 2009 based on a finding that CalPERS is an “arm of the State.” In April 2010, in response to a motion by the defendants, the Superior Court dismissed the claim for negligent interference with prospective economic advantage but declined to dismiss the claim for negligent misrepresentation. In October 2010, the defendants filed a special motion to dismiss the remaining negligent misrepresentation claim under California’s “anti-SLAPP” statute, which limits the maintenance of lawsuits based on speech on matters of public interest. In January 2012, the Superior Court denied the anti-SLAPP motion, ruling that, although the ratings qualify as protected speech activity under California law, the plaintiff had provided sufficient evidence in support of its claims to proceed. The defendants appealed this decision to the California Court of Appeal, which affirmed the Superior Court’s rulings in May 2014, and in September 2014, the Supreme Court of California declined to review the Court of Appeal’s decision. The action has been returned to the Superior Court, and discovery is likely to begin shortly.
	For claims, litigation and proceedings and governmental investigations and inquires not related to income taxes, where it is both probable that a liability is expected to be incurred and the amount of loss can be reasonably estimated, the Company records liabilities in the consolidated financial statements 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 other instances, because of uncertainties related to the probable outcome and/or the amount or range of loss, management does not record a liability but discloses the contingency if significant. As additional information becomes available, the Company adjusts its assessments and estimates of such matters accordingly. In view of the inherent difficulty of predicting the outcome of litigation, regulatory, governmental investigations and inquiries, enforcement and similar matters and contingencies, particularly where the claimants seek large or indeterminate damages or where the parties assert novel legal theories or the matters involve a large number of parties, the Company cannot predict what the eventual outcome of the pending matters will be or the timing of any resolution of such matters. The Company also cannot 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. However, in light of the large or indeterminate damages sought in some of them, the absence of similar court rulings on the theories of law asserted and uncertainties regarding apportionment of any potential damages, an estimate of the range of possible losses cannot be made at this time.
	Legacy Tax Matters
	Moody’s continues to have exposure to potential liabilities arising from Legacy Tax Matters. As of September 30, 2014, Moody’s has recorded liabilities for Legacy Tax Matters totaling $10.8 million. This includes liabilities and accrued interest due to New D&B arising from the 2000 Distribution Agreement. It is possible that the ultimate liability for Legacy Tax Matters could be greater than the liabilities recorded by the Company, which could result in additional charges that may be material to Moody’s future reported results, financial position and cash flows.
	In the fourth quarter of 2013, certain Legacy Tax Matters were resolved, resulting in a $19.2 million reduction of Legacy Tax liabilities and a $3.6 million reduction of related accrued interest expense.
	In the third quarter of 2014, the year 2010 Legacy Tax Matters statute of limitations lapsed, resulting in a $6.4 million reduction of Legacy Tax liabilities and a $0.7 million reduction of related accrued interest expense.

SEGMENT INFORMATION	'
	NOTE 15. SEGMENT INFORMATION
	Beginning in January 2014, pursuant to certain management realignment, the Company revised its operating segments. Accordingly, the Company is now organized into four operating segments: (i) MIS, (ii) MA, (iii) Copal Amba and (iv) an immaterial operating segment that provides fixed income pricing services and research in the Asia-Pacific region. The Copal Amba and the immaterial operating segment have been aggregated with the MA operating segment to form the MA reportable segment based on the determination that all of the operating segments demonstrate similar economic characteristics. Accordingly, the Company continues to be organized into two reportable segments: (i) MIS and (ii) MA. The MIS segment is comprised of all of the Company’s ratings activities. All of Moody’s other non-rating commercial activities are included in the MA reportable segment. Revenue from the Copal Amba operating segment continues to be reported within the PS LOB while revenue from the immaterial operating segment that provides fixed income pricing services and research in the Asia-Pacific region continues to be reported within RD&A.
	The MIS segment consists of four lines of business—corporate finance, structured finance, financial institutions and public, project and infrastructure finance—that 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 MA segment, which includes all of the Company’s non-rating commercial activities, develops a wide range of products and services that support the risk management activities of institutional participants in global financial markets. The MA segment consists of three lines of business – RD&A, ERS and PS.
	In December 2013, a subsidiary of the Company acquired Amba, a provider of investment research and quantitative analytics for global financial institutions. Amba is part of the MA reportable segment and its revenue is included in the PS LOB. In July 2014, a subsidiary of the Company acquired WebEquity, a leading provider of cloud-based loan origination solutions for financial institutions. WebEquity is part of the MA reporting segment and its revenue is included in the ERS LOB.
	Revenue for MIS and expenses for MA include an intersegment royalty charged to MA for the rights 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 which exclusively benefit only one segment, are fully charged to that segment. Overhead costs and corporate expenses of the Company which benefit both segments are allocated to each segment based on a revenue-split methodology. Overhead expenses include costs such as rent and occupancy, information technology and support staff such as finance, human resources and information technology. “Eliminations” in the table below represent intersegment revenue/expense.
	Financial Information by Segment
	The table below shows revenue, Adjusted Operating Income and operating income by reportable segment. Adjusted Operating Income is a financial metric utilized by the Company’s chief operating decision maker to assess the profitability of each reportable segment.

RECENTLY ISSUED ACCOUNTING STANDARDS	'
	NOTE 16. RECENTLY ISSUED ACCOUNTING STANDARDS
	In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers”. 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. This ASU is effective for annual and interim reporting periods beginning after December 15, 2016 and early adoption is not permitted. The Company is currently evaluating its adoption options and the impact that adoption of this update will have on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period.” This ASU clarifies the current accounting guidance for entities that issue share-based payment awards that require a specific performance target be achieved for employees to become eligible to vest in the awards, which may occur subsequent to a required service period. The current accounting guidance does not explicitly address how to account for these types of award. The ASU provides explicit guidance and clarifies that these types of performance targets should be treated as performance conditions, and accordingly should not be reflected in the determination of the grant-date fair value of the award. This ASU is effective for all annual periods and interim reporting periods beginning after December 15, 2015, with early adoption permitted. The Company currently accounts for transactions involving stock-based compensation awards with performance conditions in accordance with the provisions set forth in this ASU. Accordingly, the adoption of this update will not have an impact on the Company's consolidated financial statements.

	NOTE 7. ACQUISITIONS
	The acquisitions described below are accounted for using the acquisition method of accounting whereby assets acquired and liabilities assumed were recognized at their acquisition date fair value.  Any excess of the purchase price over the fair value of the assets acquired and liabilities assumed was recorded to goodwill. For the acquisitions described below, the Company has not presented proforma combined results because the impact on previously reported statements of operations would not have been material. These acquisitions are discussed below in more detail.

	WebEquity Solutions, LLC
	Amba Investment Services
	On December 10, 2013, Copal Partners Limited, a majority-owned subsidiary of the Company, acquired 100% of Amba Investment Services, a provider of outsourced investment research and quantitative analytics for global financial institutions.

ICRA Limited
On June 26, 2014, a subsidiary of the Company acquired 2,154,722 additional shares of ICRA Limited, a publicly traded company in India, pursuant to a conditional open tender offer which was initiated in February 2014. ICRA is a leading provider of credit ratings and research in India and will extend MIS’s reach in the growing domestic debt market in India as well as other emerging markets in the region. The acquisition of the additional shares increased Moody’s ownership stake in ICRA from 28.5% to 50.06%, resulting in a controlling interest in ICRA. Accordingly, the Company will consolidate ICRA’s financial statements and as of September 30, 2014, ICRA’s balance sheet was consolidated. Moody’s will consolidate ICRA’s financial statements on a three month lag, and accordingly, did not consolidate ICRA’s operating results for the third quarter and will consolidate only one quarter of ICRA’s operating results in 2014.
Prior to the acquisition of the additional shares, Moody’s accounted for its investment in ICRA on an equity basis whereby the Company recorded its proportional share of the investment’s net income or loss as part of other non-operating income (expense), net. The acquisition of the additional shares has resulted in the Company consolidating ICRA into its financial statements. As a result of this consolidation and in accordance with ASC 805, the carrying value of the Company’s equity investment in ICRA was remeasured to fair value as of the acquisition date resulting in a pre-tax gain of $102.8 million ($78.5 million after-tax) in the nine months ended September 30, 2014. The fair value of the Company’s equity investment was based on ICRA’s quoted market price on the date of acquisition.
The Company incurred approximately $2 million of costs directly related to the acquisition of ICRA during the nine months ended September 30, 2014 which are recorded within selling, general and administrative expenses in the Company’s consolidated statements of operations.
The table below details the total consideration relating to the ICRA step-acquisition:
