MSCI Inc., together with its wholly owned subsidiaries (the “Company” or “MSCI”) provides critical decision support tools and services that bring greater transparency to the global financial markets. MSCI’s tools and services include indexes; portfolio construction tools and risk-management services; environmental, social and governance (“ESG”) research and ratings; and real estate benchmarks, return analytics services and market insights; much of which can be accessed by clients through multiple channels and platforms.

These unaudited condensed consolidated financial statements include the accounts of MSCI and its wholly owned subsidiaries and include all adjustments of a normal, recurring nature necessary to state fairly the financial condition as of ~~June~~September 30, 2020 and December 31, 2019, the results of operations, comprehensive income and shareholders’ equity (deficit) for the three and ~~six~~nine months ended ~~June~~September 30, 2020 and 2019 and cash flows for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019. The unaudited condensed consolidated statement of financial condition and related financial statement information as of December 31, 2019 have been derived from the 2019 audited consolidated financial statements but do not include all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”). The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in MSCI’s Annual Report on Form 10-K for the year ended December 31, 2019. The results of operations for interim periods are not necessarily indicative of results for the entire year.

The Company’s unaudited condensed consolidated financial statements are prepared in accordance with GAAP. These accounting principles require the Company to make certain estimates and judgments that can affect the reported amounts of assets and liabilities as of the date of the unaudited condensed consolidated financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Significant estimates and assumptions made by management include the deferral and recognition of revenue, research and development and software capitalization, assessment of impairment of long-lived assets, accrued compensation, income taxes, incremental borrowing rates and other matters that affect the unaudited condensed consolidated financial statements and related disclosures. The Company believes that estimates used in the preparation of these unaudited condensed consolidated financial statements are reasonable; however, actual results could differ materially from these estimates. Intercompany balances and transactions are eliminated in consolidation.

For the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, BlackRock, Inc. accounted for 10.9% and ~~11.6%~~11.5% of the Company’s consolidated operating revenues, respectively. For the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, BlackRock, Inc. accounted for ~~17.9%~~17.8% and ~~19.4%~~18.9% of the Index segment operating revenues, respectively. NaN single customer represented 10.0% or more of operating revenues within the Analytics and All Other segments for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019.

Following the adoption of Accounting Standards Update No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” effective beginning January 1, 2020, the Company records an allowance on customer accounts at the time of billing based on the estimated amount of the billing that will not be collected.

Changes in the allowance for credit losses on doubtful accounts receivable from December 31, 2018 to ~~June~~September 30, 2020 were as follows:

	Amount			Amount
	(in thousands)			(in thousands)
Balance as of December 31, 2018	$	1,027		$	1,027
Addition (reduction) to credit loss expense		1,024			1,024

In June 2016, the FASB issued Accounting Standards Update No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments,” or ASU 2016-13. The amendments in ASU 2016-13 introduce an approach based on expected losses to estimated credit losses on certain types of financial instruments, modify the impairment model for available-for-sale debt securities and provide for a simplified accounting model for purchased financial assets with credit deterioration since their origination.

The FASB issued Accounting Standards Update No. 2018-19, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses,” or ASU 2018-19, Accounting Standards Update No. 2019-04, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses,” or ASU 2019-04, Accounting Standards Update No. 2019-05, “Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief,” or ASU 2019-05, Accounting Standards Update No. 2019-10, “Financial Instruments-Credit Losses (Topic 326): Effective Dates,” or ASU 2019-10 and Accounting Standards Update No. 2019-11, “Codification Improvements to Topic 326, Financial Instruments—Credit Losses,” or ASU 2019-11. The amendments in these ASUs provide clarifications to ASU 2016-13.

The Company adopted ASU 2016-13 and the related clarifications effective January 1, 2020. The adoption did not have a material effect on the Company’s condensed consolidated financial statements.

In January 2017, the FASB issued Accounting Standards Update No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” or ASU 2017-04. The amendments in ASU 2017-04 simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity performed procedures to determine the fair value at the impairment testing date of its assets and liabilities. When applying the amendments in ASU 2017-04, an entity performs its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and recognizes an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, but not more than the total amount of goodwill allocated to the reporting unit. The Company adopted ASU 2017-04 effective January 1, 2020.

MSCI’s revenues are characterized by product type, which broadly reflects the nature of how they are recognized. The Company’s revenue types are recurring subscription, asset-based fees and non-recurring revenues. The Company also reports revenues by segment.

The amounts of revenue recognized in the periods that were included in the opening current deferred revenue, which reflects contract liability amounts, were ~~$385.6~~$494.4 million and ~~$367.2~~$464.3 million for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, respectively. The difference between the opening and closing balances of the Company’s deferred revenue was primarily driven by an increase in the amortization of deferred revenue to operating revenues, partially offset by an increase in billings. MSCI had an insignificant long-term deferred revenue balance as of ~~June~~September 30, 2020, reflected as a part of “Other non-current liabilities” on its Unaudited Condensed Consolidated Statement of Financial Condition.

For contracts that have a duration of one year or less, the Company has not disclosed either the remaining performance obligation as of the end of the reporting period or when the Company expects to recognize the revenue. The remaining performance obligations for contracts that have a duration of greater than one year and the periods in which they are expected to be recognized are as follows:

Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding during the period. Common shares outstanding include common stock and vested restricted stock unit awards where recipients have satisfied either the explicit vesting terms or retirement-eligible requirements. Diluted EPS reflects the assumed conversion of all dilutive securities.

The Company’s provision for income taxes was ~~an expense of $38.8~~$45.5 million and ~~a benefit of $15.8~~$15.9 million for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, respectively. These amounts reflect effective tax rates of ~~12.8%~~9.3% and ~~negative 5.5%~~3.5% for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, respectively.

The effective tax rate of ~~12.8%~~9.3% for the ~~six~~nine months ended ~~June~~September 30, 2020 reflects the Company’s estimate of the effective tax rate for the period and was impacted by certain discrete items totaling ~~$34.1~~$61.7 million. For the ~~six~~nine months ended ~~June~~September 30, 2020, these discrete items primarily related to ~~$21.5~~$21.9 million of excess tax benefits recognized on the conversion of equity awards during the period, $20.8 million related to the favorable impact on prior years of final regulations released duringthe three months ended September 30, 2020clarifying certain provisions established in the Tax Cuts and Jobs Act that was enacted on December 22, 2017 (“2017 Tax Act”) and $11.5 million related to the tax impact of loss on debt extinguishment recognized during the period on the redemption of the 2024 Senior Notes and 2025 Senior Notes. Also included in the discrete items is a ~~$0.8~~$6.3 million benefit related to the revaluation of the cost of deemed repatriation of foreign earnings. ~~In addition, the effective tax rate was impacted by a beneficial geographic mix of earnings.~~

The effective tax rate of ~~negative 5.5%~~3.5% for the ~~six~~nine months ended ~~June~~September 30, 2019 reflects the Company’s estimate of the effective tax rate for the period and was impacted by certain discrete items totaling ~~$78.6~~$82.7 million. For the ~~six~~nine months ended ~~June~~September 30, 2019, these discrete items primarily related to $66.6 million of excess tax benefits recognized on the conversion during the period of certain multi-year restricted stock units that were subject to the achievement of multi-year total shareholder return targets (performance targets subject to market conditions) granted in 2016 (“2016 multi-year PSUs”) and ~~$11.0~~$10.8 million of excess tax benefits related to the conversion of other equity awards recognized during the period. In addition, the effective tax rate was impacted by a beneficial geographic mix of earnings.

During the ~~six~~nine months ended ~~June~~September 30, 2020, a number of countries enacted economic stimulus laws including the CARES Act in the U.S. The Company has evaluated the laws that were passed during the ~~six~~nine months ended ~~June~~September 30, 2020 and does not believe the laws have a material impact on the Company’s effective tax rate or cash flows. A number of the laws, however, have enabled the Company to defer certain eligible tax payments that would have fallen due ~~into later~~in earlier quarters.

The Company is under examination by the IRS and other tax authorities in certain jurisdictions, including foreign jurisdictions, such as the United Kingdom, Switzerland and India, and states in which the Company has significant operations, such as New York. The tax years currently under examination vary by jurisdiction but include years ranging from 2007 through 2019.

The Company regularly assesses the likelihood of additional assessments in each of the taxing jurisdictions in which it files income tax returns. The Company has established unrecognized tax benefits that the Company believes are adequate in relation to the potential for additional assessments. Once established, the Company adjusts unrecognized tax benefits only when more information is available or when an event occurs necessitating a change. As part of the Company’s periodic review of unrecognized tax benefits and based on new information regarding the status of federal and state examinations, the Company’s unrecognized tax benefits were remeasured. Based on the current status of income tax audits, the total amount of unrecognized benefits may decrease by approximately $9.6 million in the next twelve months as a result of the resolution of tax examinations.

ASC Subtopic 280-10, “Segment Reporting,” establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or CODM, in deciding how to allocate resources and assess performance. MSCI’s Chief Executive Officer and its President and Chief Operating Officer, who are together considered to be its CODM, review financial information presented on an operating segment basis for purposes of making operating decisions and assessing financial performance.

The CODM measures and evaluates reportable segments based on segment operating revenues as well as Adjusted EBITDA and other measures. The Company excludes the following items from segment Adjusted EBITDA: provision for income taxes, other expense (income), net, depreciation and amortization of property, equipment and leasehold improvements, amortization of intangible assets and, at times, certain other transactions or adjustments, including the impact related to the vesting of the 2016 Multi-Year PSUs, that the CODM does not consider for the purposes of making decisions to allocate resources among segments or to assess segment performance. Although these amounts are excluded from segment Adjusted EBITDA, they are included in reported consolidated net income and are included in the reconciliation that follows.

The Company’s computation of segment Adjusted EBITDA may not be comparable to other similarly titled measures computed by other companies because all companies do not calculate segment Adjusted EBITDA in the same fashion.

Operating revenues and expenses directly associated with each segment are included in determining its operating results. Other expenses that are not directly attributable to a particular segment are based upon allocation methodologies, including time estimates, revenue, headcount, sales targets, data center consumption and other relevant usage measures. Due to the integrated structure of MSCI’s business, certain costs incurred by one segment may benefit other segments. A segment may use the content and data produced by another segment without incurring an arm’s-length intersegment charge.

The CODM does not review any information regarding total assets on an operating segment basis. Operating segments do not record intersegment revenues, and, accordingly, there is none to be reported. The accounting policies for segment reporting are the same as for MSCI as a whole.

The Company has 5 operating segments: Index, Analytics, ESG, Real Estate and The Burgiss Group, LLC (“Burgiss”).

The Index operating segment is a provider of primarily equity indexes. The indexes are used in many areas of the investment process, including index-linked product creation (e.g., ~~ETFs~~Exchange Traded Funds (“ETFs”) and futures and options), performance benchmarking, portfolio construction and rebalancing, broker-dealer structured products and asset allocation.

The Analytics operating segment offers risk management, performance attribution and portfolio management content, applications and services that provide clients with an integrated view of risk and return and an analysis of market, credit, liquidity and counterparty risk across all major asset classes, spanning short-, medium- and long-term time horizons. Clients access Analytics content through MSCI’s own proprietary applications and application programming interfaces, third-party applications or directly through their own platforms. Additionally, the Analytics operating segment also provides various managed services to help clients operate more efficiently, including consolidation of client portfolio data from various sources, review and reconciliation of input data and results, and customized reporting.

The ESG operating segment offers products and services that help institutional investors understand how ESG considerations can impact the long-term risk and return of their portfolio and individual security-level investments. In addition, MSCI ESG Research data and ratings are used in the construction of equity and fixed income indexes to help institutional investors more effectively benchmark ESG investment performance, issue index-based investment products, as well as manage, measure and report on ESG mandates.

The Real Estate operating segment offers research, reporting, market data and benchmarking offerings that provide real estate performance analysis for funds, investors and managers. Real Estate performance and risk analytics range from enterprise-wide to property-specific analysis. The Real Estate operating segment also provides business intelligence to real estate owners, managers, developers and brokers worldwide.

The Burgiss operating segment represents the Company’s equity method investment in Burgiss, a global provider of investment decision support tools for private capital. See Note 12, “Equity Method Investments,” for further information.

The operating segments of ESG, Real Estate and Burgiss do not individually meet the segment reporting thresholds and have been combined and presented as part of All Other for disclosure purposes. Burgiss is an equity-method investment, therefore, the All Other segment does not include the Company’s proportionate share of operating revenues and Adjusted EBITDA related to Burgiss. The Company’s proportionate share of Burgiss’s equity earnings is not a component of Adjusted EBITDA as it is reported as a component of other (expense) income, net.

In January 2020, MSCI entered into a strategic relationship with Burgiss, a global provider of investment decision support tools for private capital. The Company acquired a 40% non-controlling interest for $190.8 million, including capitalized costs, which is accounted for as an equity method investment with the Company’s share of Burgiss’ earnings being recognized in “Other expense (income), net” in the Condensed Consolidated Statements of Income. The Company is applying a policy election to recognize its share of Burgiss’ earnings on a three-month lag. Accordingly, the Company has recognized in its results of operations ~~for the first time~~ an immaterial amount in earnings related to its investment in Burgiss in both the three months and ~~six~~nine months ended ~~June~~September 30, 2020. MSCI has also elected to apply the nature of the distribution approach to determine the classification of the distributions it receives from its equity method ~~investees.~~investee. In the three months ended September 30, 2020, MSCI received an immaterial amount in distributions from its equity method investee.

The Company’s investment substantially exceeds the Company’s share of the underlying equity of Burgiss. A portion of this excess, representing the excess of the fair value of Burgiss’ intangible assets over their book value, is amortized into “Other expense (income), net” over the useful lives of the respective intangible assets.

On ~~July 27,~~October 26, 2020, the Board of Directors declared a quarterly cash dividend of $0.78 per share for the three months ending ~~September 30,~~December 31, 2020 (“~~third~~fourth quarter 2020”). The ~~third~~fourth quarter 2020 dividend is payable on ~~August 31,~~November 30, 2020 to shareholders of record as of the close of trading on ~~August 14,~~November 13, 2020.

Subsequent to the nine months ended September 30, 2020 and through October 23, 2020, the Company repurchased an additional 0.1 million shares of common stock at an average price of $347.26 per share for a total value of $51.0 million.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of the financial condition and results of operations should be read in conjunction with the condensed consolidated financial statements and related notes included elsewhere in this Form 10-Q and in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (the “Form 10-K”). This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in “Item 1A.—Risk Factors,” in our Form 10-K.

Except as the context otherwise indicates, the terms “MSCI,” the “Company,” “we,” “our” and “us” refer to MSCI Inc., together with its subsidiaries.

Through our integrated franchise we provide solutions across our products and services to support our clients’ dynamic and complex needs. We are flexible in the delivery of our content and capabilities, much of which can be accessed by our clients through multiple channels and platforms.

We are focused on staying at the forefront of investment trends to address the evolving needs of our clients in a changing industry. In order to most effectively serve our clients, we are committed to driving an integrated solutions-based approach, achieving service excellence, enhancing our differentiated research and content, and delivering flexible, cutting-edge technology and platforms.

Our clients comprise a wide spectrum of the global investment industry and include the following key client types:

As of ~~June~~September 30, 2020, we served over ~~7,800~~7,900 clients in more than 90 countries. To calculate the number of clients, we use the shipping address of the ultimate customer utilizing the product, which counts affiliates, user locations or business units within a single organization as separate clients. If we aggregate all related clients under their respective parent entity, the number of clients would be over 4,300, as of ~~June~~September 30, 2020. As of ~~June~~September 30, 2020, we had offices in more than 3530 cities across more than 2220 countries to help serve our diverse client base, with ~~47.4%~~47.1% of our revenues coming from clients in the Americas, ~~37.0%~~36.9% in EMEA and ~~15.6%~~16.0% in Asia and Australia.

Our principal business model is generally to license annual, recurring subscriptions for the majority of our Index, Analytics and ESG products and services for a fee due in advance of the service period. We also license annual recurring subscriptions for the majority of our Real Estate products for a fee which is primarily paid in arrears after the product is delivered, with the exception of the Market Information product for which the fees are generally paid in advance. A portion of our fees comes from clients who use our indexes as the basis for index-linked investment products. Such fees are primarily based on a client’s assets under management (“AUM”), trading volumes and fee levels.

In evaluating our financial performance, we focus on revenue and profit growth, including results accounted for under accounting principles generally accepted in the United States (“GAAP”) as well as non-GAAP measures, for the Company as a whole and by operating segment. In addition, we focus on operating metrics, including Run Rate, subscription sales and Retention Rate, to manage the business. Our business is not highly capital intensive and, as such, we expect to continue to convert a high percentage of our profits into excess cash in the future. Our growth strategy includes: (a) expanding leadership in research-enhanced content, (b) strengthening existing and new client relationships by providing solutions, (c) improving access to our solutions through cutting-edge technology and platforms, (d) expanding value-added service offerings and (e) executing strategic relationships and acquisitions with complementary content and technology companies.

In the discussion that follows, we provide certain variances excluding the impact of foreign currency exchange rate fluctuations. Foreign currency exchange rate fluctuations reflect the difference between the current period results as reported compared to the current period results recalculated using the foreign currency exchange rates in effect for the comparable prior period. While operating revenues adjusted for the impact of foreign currency fluctuations includes asset-based fees that have been adjusted for the impact of foreign currency fluctuations, the underlying AUM, which is the primary component of asset-based fees, is not adjusted for foreign currency fluctuations. Approximately two-thirds of the AUM are invested in securities denominated in currencies other than the U.S. dollar, and accordingly, any such impact is excluded from the disclosed foreign currency-adjusted variances.

The discussion of our results of operations for the three and ~~six~~nine months ended ~~June~~September 30, 2020 and 2019 are presented below. The results of operations for interim periods may not be indicative of future results.

Adjusting for the impact of foreign currency exchange rate fluctuations, the increase would have been ~~6.4%~~7.5% for the three months ended ~~June~~September 30, 2020 compared to the three months ended ~~June~~September 30, 2019.

For the ~~six~~nine months ended ~~June~~September 30, 2020, the increase was ~~9.2%~~8.7%, growing to ~~$826.4~~$1,251.7 million compared to ~~$756.9~~$1,151.2 million for the ~~six~~nine months ended ~~June~~September 30, 2019. ~~Adjusting for the~~The impact of foreign currency exchange rate fluctuations ~~the increase would have been 9.3% for the six months ended June 30, 2020 compared to the six months ended June 30, 2019.~~on total operating revenues was negligible.

As a result of the impact of the COVID-19 pandemic, growth in operating revenues from recurring subscriptions may moderate in the near term. In addition, the volatility in the global equity markets may adversely impact AUM levels which in turn may impact future operating revenues from asset-based fees.

Operating revenues from recurring subscriptions for the three months ended ~~June~~September 30, 2020 increased ~~7.2%~~8.7% to ~~$309.9~~$313.2 million compared to ~~$289.1~~$288.1 million for the three months ended ~~June~~September 30, 2019, primarily driven by growth in Index products, which increased ~~$13.3~~$13.0 million, or ~~10.0%~~9.7%, growth in ESG products, which increased ~~$4.8~~$5.6 million, or ~~22.7%~~24.8%, and growth in Analytics products, which increased ~~$4.5~~$4.1 million, or ~~3.7%~~3.4%.

The increase in asset-based fees was primarily driven by ~~a strong~~an increase in revenues from ~~exchange traded futures and options contracts~~ETFs linked to MSCI indexes and ~~an increase in revenues from~~ non-ETF indexed funds ~~linked to MSCI indexes, offset by a decline in revenues from ETFs~~ linked to MSCI indexes. The increase in revenues from ~~exchange traded futures and options contracts~~ETFs linked to MSCI indexes was ~~primarily~~ driven by ~~price increases.~~a 10.2% increase in average AUM in equity ETFs, partially offset by the impact of a change in product mix. Revenue growth from non-ETF indexed funds linked to MSCI indexes was primarily driven by an increase in average AUM. The ~~decline in revenues from ETFs linked to MSCI indexes was driven by a 4.3% decrease in average AUM and by the impact of a change in product mix. The~~ impact of foreign currency exchange rate fluctuations on revenues from asset-based fees was negligible.

For the ~~six~~nine months ended ~~June~~September 30, 2020, revenues from asset-based fees increased ~~11.0%~~8.7% to ~~$188.3~~$288.6 million compared to ~~$169.5~~$265.6 million for the ~~six~~nine months ended ~~June~~September 30, 2019. The increase in asset-based fees was primarily driven by a strong increase in revenues from exchange traded futures and options contracts linked to MSCI indexes, primarily driven by price and volume increases. The increase was also driven by higher revenues from non-ETF indexed funds linked to MSCI indexes, primarily driven by an increase in average AUM. The impact of foreign currency exchange rate fluctuations on revenues from asset-based fees was negligible.

G&A expenses consist of costs primarily related to finance operations, human resources, office of the CEO, legal, corporate technology, corporate development and certain other administrative costs that are not directly attributed, but are instead allocated, to a product or service.

G&A expenses for the three months ended ~~June~~September 30, 2020 increased ~~7.3%~~4.0% to ~~$28.3~~$27.6 million compared to ~~$26.4~~$26.6 million for the three months ended ~~June~~September 30, 2019, reflecting increases across all three reportable segments. The change was driven by increases in compensation and benefits costs, primarily relating to higher ~~incentive compensation and wages and salaries,~~severance costs, partially offset by ~~lower severance~~decreases in non-compensation costs.

For the ~~six~~nine months ended ~~June~~September 30, 2020, the increase was ~~9.8%~~7.9%, growing to ~~$59.1~~$86.8 million compared to ~~$53.9~~$80.4 million for the ~~six~~nine months ended ~~June~~September 30, 2019, reflecting increases across all three reportable segments. The change was driven by increases in compensation and benefits costs, primarily relating to higher incentive compensation, wages and salaries and ~~benefits~~severance costs, partially offset by the absence of $3.5 million of payroll tax expense associated with the vesting of the 2016 Multi-Year PSUs recognized in ~~2019.~~2019 and lower non-compensation costs.

The following table presents operating expenses using compensation and non-compensation categories, rather than using activity categories, for the periods indicated:

Compensation and benefits costs are our most significant expense and typically represent approximately 65% of operating expenses or more than 70% of Adjusted EBITDA expenses. We had ~~3,513~~3,545 and ~~3,266~~3,358 employees as of ~~June~~September 30, 2020 and 2019, respectively, reflecting a ~~7.6%~~5.6% growth in the number of employees. Continued growth of our emerging market centers around the world is an important factor in our ability to manage and control the growth of our compensation and benefit expenses. As of ~~June~~September 30, 2020, ~~63.7%~~64.2% of our employees were located in emerging market centers compared to ~~62.8%~~63.3% as of ~~June~~September 30, 2019.

Compensation and benefits costs for the three months ended ~~June~~September 30, 2020 increased ~~3.6%~~6.5% to ~~$128.8~~$129.9 million compared to ~~$124.3~~$122.0 million for the three months ended ~~June~~September 30, 2019, driven by higher severance costs, wages and salaries and benefits costs, partially offset by lower incentive compensation costs.

For the nine months ended September 30, 2020, the increase was 1.9%, growing to $396.0 million compared to $388.5 million for the nine months ended September 30, 2019, primarily driven by higher ~~incentive compensation and~~ wages and salaries, benefits costs and severance costs, partially offset ~~by lower severance costs.~~

~~For the six months ended June 30, 2020, the decrease was 0.2%, declining to $266.1 million compared to $266.5 million for the six months ended June 30, 2019, primarily driven~~ by the absence of $15.4 million of payroll tax expense associated with the vesting of the 2016 Multi-Year PSUs recognized in ~~2019, partially offset by higher wages and salaries, incentive compensation and benefits costs.~~2019.

A significant portion of the incentive compensation component of operating expenses is based on the achievement of a number of financial and operating metrics. In a scenario where operating revenue growth and profitability moderate as a result of the impact of the COVID-19 pandemic, incentive compensation is expected to decrease accordingly.

Non-compensation expenses for the three months ended ~~June~~September 30, 2020 decreased ~~10.8%~~10.7% to ~~$44.1~~$46.0 million compared to ~~$49.4~~$51.5 million for the three months ended ~~June~~September 30, 2019, primarily driven by lower travel and entertainment costs ~~marketing costs~~ and ~~recruiting costs, partially offset by higher information technology costs.~~professional fees.

For the ~~six~~nine months ended ~~June~~September 30, 2020, the decrease was ~~2.0%~~5.0%, declining to ~~$94.4~~$140.4 million compared to ~~$96.3~~$147.8 million for the ~~six~~nine months ended ~~June~~September 30, 2019, primarily driven by lower travel and entertainment ~~costs,~~and marketing ~~costs and recruiting~~ costs, partially offset by higher information technology ~~costs, professional fees and occupancy~~ costs.

Fixed costs constitute a significant portion of the non-compensation component of operating expenses. The discretionary non-compensation component of operating expenses could, however, be reduced in the near-term in a scenario where operating revenue growth moderates as a result of the COVID-19 pandemic.

Amortization of intangible assets expense relates to definite-lived intangible assets arising from past acquisitions and internal capitalized software projects recognized over their estimated useful lives. Amortization of intangible assets expense for the three months ended ~~June~~September 30, 2020 increased ~~17.1%~~16.0% to ~~$14.1~~$14.3 million compared to ~~$12.0~~$12.4 million for the three months ended ~~June~~September 30, 2019, primarily driven by higher amortization of internally developed capitalized software.

For the ~~six~~nine months ended ~~June~~September 30, 2020, it increased ~~16.9%~~16.6% to ~~$27.8~~$42.2 million compared to ~~$23.8~~$36.2 million for the ~~six~~nine months ended ~~June~~September 30, 2019, primarily driven by higher amortization of internally developed capitalized software.

Depreciation and amortization of property, equipment and leasehold improvements consists of expenses related to depreciating or amortizing the cost of furniture and fixtures, computer and related equipment and leasehold improvements over the estimated useful life of the assets. Depreciation and amortization of property, equipment and leasehold improvements for the three months ended ~~June~~September 30, 2020 ofincreased 4.0% to $7.5 million ~~remained consistent~~ compared to $7.2 million for the three months ended ~~June 30, 2019.~~

~~For the six months ended June 30, 2020, it decreased 1.5% to $15.0 million compared to $15.3 million for the six months ended June~~September 30, 2019. The ~~decrease~~increase was primarily the result of ~~lower depreciation on leasehold improvements, partially offset by~~ higher depreciation on computer and related ~~equipment.~~equipment and furniture.

For the nine months ended September 30, 2020, it remained consistent at $22.5 million compared to the nine months ended September 30, 2019.

Other expense (income), net for the three months ended ~~June~~September 30, 2020 increased ~~132.9%~~18.8% to ~~$76.0~~$38.6 million compared to ~~$32.6~~$32.5 million for the three months ended ~~June~~September 30, 2019. The increase in net expenses was primarily driven by lower interest income due to lower rates earned on cash balances and higher interest expense associated with the higher outstanding debt during the three months ended September 30, 2020.

For the nine months ended September 30, 2020, it increased 60.4% to $159.6 million compared to $99.5 million for the nine months ended September 30, 2019. The increase in net expenses was primarily driven by the $35.0 million and $10.0 million loss on debt extinguishment ~~recognized on~~associated with the redemption of all of the outstanding $800.0 million aggregate principal amount of the 2025 Senior Notes (“2025 Senior Notes Redemption”). and the redemption of all of the remaining $300.0 million of the 5.250% Senior Notes due 2024 (“2024 Senior Notes Redemption”), respectively. The loss on debt extinguishment associated with the 2025 Senior Notes included an applicable premium of approximately $29.5 million (as defined in the indenture governing the terms of the 2025 Senior Notes) and the write-off of approximately $5.5 million of unamortized debt issuance costs. In addition, the increase reflects higher interest expense associated with the higher outstanding debt during the three months ended June 30, 2020 and lower interest income due to lower rates earned on cash balances.

For the six months ended June 30, 2020, it increased 80.6% to $121.0 million compared to $67.0 million for the six months ended June 30, 2019.

The loss on debt extinguishment associated with the 2024 Senior Notes Redemption ~~includes~~included a redemption price of approximately $7.9 million (as set forth in the indenture governing the terms of the 2024 Senior Notes) and the write-off of approximately $2.1 million of unamortized debt issuance costs. In addition, the increase reflects higher interest expense associated with the higher outstanding debt during the ~~six~~nine months ended ~~June~~September 30, 2020 and lower interest income due to lower rates earned on cash ~~balances, partially offset by higher foreign currency exchange gains.~~balances.

The Company’s provision for income taxes for the three months ended ~~June~~September 30, 2020 and 2019 was ~~$24.0~~$6.7 million and ~~$34.1~~$31.8 million, respectively. These amounts reflect effective tax rates of ~~17.3%~~3.5% and ~~21.3%~~18.8% for the three months ended ~~June~~September 30, 2020 and 2019, respectively.

For the three months ended ~~June~~September 30, 2020, the effective tax rate of ~~17.3%~~3.5% reflects the Company’s estimate of the effective tax rate for the period which was impacted by certain favorable discrete items totaling ~~$11.7~~$27.7 million. These discrete items primarily related to the ~~$9.0~~$20.8 million tax impact from the favorable impact on prior years of ~~loss on debt extinguishment recognized~~final regulations released during the ~~period on~~three months ended September 30, 2020 clarifying certain provisions established in the ~~2025 Senior Notes Redemption and $2.3~~2017 Tax Act.

In addition, the effective tax rate was also impacted by a beneficial geographic mix of earnings and lower anticipated taxes on the repatriation of foreign earnings. In addition, the effective tax rate was impacted by certain discrete items totaling $0.8 million. These discrete items included $1.2 million of excess tax benefits related to the conversion of equity awards.

The Company’s provision for income taxes for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019 was ~~an expense of $38.8~~$45.5 million and ~~a benefit of $15.8~~$15.9 million, respectively. These amounts reflect effective tax rates of ~~12.8%~~9.3% and ~~negative 5.5%~~3.5% for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, respectively.

The decreases primarily reflect the impact of share repurchases made prior to ~~June~~September 30, 2020 pursuant to the 2019 Repurchase Program and the vesting of the restricted stock units that were included in the dilutive share count in the prior year.

For the ~~six~~nine months ended ~~June~~September 30, 2020 compared to the ~~six~~nine months ended ~~June~~September 30, 2019, the weighted average shares outstanding remained ~~consistent.~~flat.

“Adjusted EBITDA,” a non-GAAP measure used by management to assess operating performance, is defined as net income before (1) provision for income taxes, (2) other expense (income), net, (3) depreciation and amortization of property, equipment and leasehold improvements, (4) amortization of intangible assets and, at times, (5) certain other transactions or adjustments, including the impact related to the vesting of the 2016 Multi-Year PSUs.

“Adjusted EBITDA expenses,” a non-GAAP measure used by management to assess operating performance, is defined as operating expenses less depreciation and amortization of property, equipment and leasehold improvements and amortization of intangible assets and, at times, certain other transactions or adjustments, including the impact related to the vesting of the 2016 Multi-Year PSUs.

Adjusted EBITDA and Adjusted EBITDA expenses are believed to be meaningful measures of the operating performance of the Company because they adjust for significant one-time, unusual or non-recurring items as well as eliminate the accounting effects of certain capital spending and acquisitions that do not directly affect what management considers to be the Company’s ongoing operating performance in the period. All companies do not calculate adjusted EBITDA and adjusted EBITDA expenses in the same way. These measures can differ significantly from company to company depending on, among other things, long-term strategic decisions regarding capital structure, the tax jurisdictions in which companies operate and capital investments. Accordingly, the Company’s computation of the Adjusted EBITDA and Adjusted EBITDA expenses measures may not be comparable to similarly titled measures computed by other companies.

The following table presents the calculation of Adjusted EBITDA for the periods indicated:

“Run Rate” estimates at a particular point in time the annualized value of the recurring revenues under our client license agreements (“Client Contracts”) for the next 12 months, assuming all Client Contracts that come up for renewal are renewed and assuming then-current currency exchange rates, subject to the adjustments and exclusions described below. For any Client Contract where fees are linked to an investment product’s assets or trading volume/fees, the Run Rate calculation reflects, for ETFs, the market value on the last trading day of the period, for futures and options, the most recent quarterly volumes and/or reported exchange fees, and for other non-ETF products, the most recent client-reported assets. Run Rate does not include fees associated with “one-time” and other non-recurring transactions. In addition, we add to Run Rate the annualized fee value of recurring new sales, whether to existing or new clients, when we execute Client Contracts, even though the license start date, and associated revenue recognition, may not be effective until a later date. We remove from Run Rate the annualized fee value associated with products or services under any Client Contract with respect to which we have received a notice of termination or non-renewal during the period and have determined that such notice evidences the client’s final decision to terminate or not renew the applicable products or services, even though such notice is not effective until a later date.

Changes in our recurring revenues typically lag changes in Run Rate. The actual amount of recurring revenues we will realize over the following 12 months will differ from Run Rate for numerous reasons, including:

Sales represents the annualized value of products and services clients commit to purchase from MSCI and will result in additional operating revenues. Non-recurring sales represent the actual value of the customer agreements entered into during the period and are not a component of Run Rate. New recurring subscription sales represent additional selling activities, such as new customer agreements, additions to existing agreements or increases in price that occurred during the period and are additions to Run Rate. Subscription cancellations reflect client activities during the period, such as discontinuing products and services and/or reductions in price, resulting in reductions to Run Rate. Net new recurring subscription sales represent the amount of new recurring subscription sales net of subscription cancellations during the period, which reflects the net impact to Run Rate during the period.

Total gross sales represent the sum of new recurring subscription sales and non-recurring sales. Total net sales represent the total gross sales net of the impact from subscription cancellations.

A significant portion of MSCI's operating revenues are derived from subscriptions or licenses of products and services, which are provided over contractually-agreed periods of time that are subject to renewal or cancellation at the end of current contract terms. As of ~~June~~September 30, 2020, cancellations have not deviated significantly from historical levels as a result of the COVID-19 pandemic. However, new sales could moderate and cancellations could increase in the near term as a result of the COVID-19 pandemic.

The following table presents our Retention Rate by reportable segment for the periods indicated:

Retention Rate is an important metric because subscription cancellations decrease our Run Rate and ultimately our operating revenues over time. The annual Retention Rate represents the retained subscription Run Rate (subscription Run Rate at the beginning of the fiscal year less actual cancels during the year) as a percentage of the subscription Run Rate at the beginning of the fiscal year.

The Retention Rate for a non-annual period is calculated by annualizing the cancellations for which we have received a notice of termination or for which we believe there is an intention not to renew during the non-annual period, and we believe that such notice or intention evidences the client’s final decision to terminate or not renew the applicable agreement, even though such notice is not effective until a later date. This annualized cancellation figure is then divided by the subscription Run Rate at the beginning of the fiscal year to calculate a cancellation rate. This cancellation rate is then subtracted from 100% to derive the annualized Retention Rate for the period.

Retention Rate is computed by operating segment on a product/service-by-product/service basis. In general, if a client reduces the number of products or services to which it subscribes within a segment, or switches between products or services within a segment, we treat it as a cancellation for purposes of calculating our Retention Rate except in the case of a product or service switch that management considers to be a replacement product or service. In those replacement cases, only the net change to the client subscription, if a decrease, is reported as a cancel. In the Analytics and the ESG operating segments, substantially all product or service switches are treated as replacement products or services and netted in this manner, while in our Index and Real Estate operating segments, product or service switches that are treated as replacement products or services and receive netting treatment occur only in certain limited instances. In addition, we treat any reduction in fees resulting from a down-sale of the same product or service as a cancellation to the extent of the reduction. We do not calculate Retention Rate for that portion of our Run Rate attributable to assets in index-linked investment products or futures and options contracts, in each case, linked to our indexes.

In our product lines, Retention Rate is generally higher during the first three quarters and lower in the fourth quarter, as the fourth quarter is traditionally the largest renewal period in the year.

We describe our significant accounting policies in Note 1, “Introduction and Basis of Presentation,” of the Notes to Consolidated Financial Statements included in our Form 10-K and also in Note 2, “Recent Accounting Standards Updates,” in the Notes to ~~Unaudited~~ Condensed Consolidated Financial Statements (Unaudited) included herein. There have been no significant changes in our accounting policies or critical accounting estimates since the end of the fiscal year ended December 31, 2019 other than those described in Note 2, “Recent Accounting Standards Updates” in the Notes to ~~Unaudited~~ Condensed Consolidated Financial Statements (Unaudited) included herein.

We require capital to fund ongoing operations, internal growth initiatives and acquisitions. Our primary sources of liquidity are cash flows generated from our operations, existing cash and cash equivalents and credit capacity under our existing credit facility. In addition, we believe we have access to additional funding in the public and private markets. We intend to use these sources of liquidity to, among other things, service our existing and future debt obligations, fund our working capital requirements for capital expenditures, investments, acquisitions and dividend payments, and repurchases of our common stock. In connection with our business strategy, we regularly evaluate acquisition and strategic partnership opportunities. We believe our liquidity, along with other financing alternatives, will provide the necessary capital to fund these transactions and achieve our planned growth.

We have an aggregate of $3,400.0 million in Senior Notes outstanding and a $400.0 million undrawn Revolving Credit Agreement with a syndicate of banks. See Note 7, “Commitments and Contingencies,” of the Notes to ~~Unaudited~~ Condensed Consolidated Financial Statements (Unaudited) included herein for additional information on our Senior Notes and Revolving Credit Agreement.

The Senior Notes and the Revolving Credit Agreement are fully and unconditionally, and jointly and severally, guaranteed by our direct or indirect wholly owned domestic subsidiaries that account for more than 5% of our and our subsidiaries’ consolidated assets, other than certain excluded subsidiaries (the “subsidiary guarantors”). Amounts due under the Revolving Credit Agreement are our and the subsidiary guarantors’ senior unsecured obligations and rank equally with the Senior Notes and any of our other unsecured, unsubordinated debt, senior to any of our subordinated debt and effectively subordinated to our secured debt to the extent of the assets securing such debt.

The indentures governing our Senior Notes (the “Indentures”) among us, each of the subsidiary guarantors, and Wells Fargo Bank, National Association, as trustee, contain covenants that limit our and certain of our subsidiaries’ ability to, among other things, incur liens, enter into sale/leaseback transactions and consolidate, merge or sell all or substantially all of our assets. In addition, the Indentures restrict our non-guarantor subsidiaries’ ability to create, assume, incur or guarantee additional indebtedness without such non-guarantor subsidiaries guaranteeing the Senior Notes on a pari passu basis.

The Revolving Credit Agreement contains affirmative and restrictive covenants that, among other things, limit our ability and the ability of our existing or future subsidiaries to:

The Revolving Credit Agreement and the Indentures also contain customary events of default, including those relating to non-payment, breach of representations, warranties or covenants, cross-default and cross-acceleration, bankruptcy and insolvency events, invalidity or impairment of loan documentation or collateral, change of control and customary ERISA defaults. None of the restrictions above are expected to impact our ability to effectively operate the business.

The Revolving Credit Agreement also requires us and our subsidiaries to achieve financial and operating results sufficient to maintain compliance with the following financial ratios on a consolidated basis through the termination of the Revolving Credit Agreement: (1) the maximum Consolidated Leverage Ratio (as defined in the Revolving Credit Agreement) measured quarterly on a rolling four-quarter basis shall not exceed 4.25:1.00 and (2) the minimum Consolidated Interest Coverage Ratio (as defined in the Revolving Credit Agreement) measured quarterly on a rolling four-quarter basis shall be at least 4.00:1.00. As of ~~June~~September 30, 2020, our Consolidated Leverage Ratio was ~~3.40:~~3.31:1.00 and our Consolidated Interest Coverage Ratio was ~~5.98:~~6.81:1.00. As of ~~June~~September 30, 2020, there were no amounts drawn and outstanding under the Revolving Credit Agreement.

Our non-guarantor subsidiaries under the Senior Notes consist of: (i) domestic subsidiaries of the Company that account for 5% or less of consolidated assets of the Company and its subsidiaries and (ii) any foreign or domestic subsidiary of the Company that is deemed to be a controlled foreign corporation within the meaning of Section 957 of the Internal Revenue Code of 1986, as amended. Our non-guarantor subsidiaries accounted for approximately ~~$925.6~~$956.6 million, or ~~56.9%~~57.7%, of our total revenue for the trailing 12 months ended ~~June~~September 30, 2020, approximately ~~$310.5~~$341.0 million, or ~~37.7%~~40.1%, of our consolidated operating income for the trailing 12 months ended ~~June~~September 30, 2020, and approximately ~~$891.9~~$947.0 million, or ~~21.2%~~23.0%, of our consolidated total assets (excluding intercompany assets) and ~~$614.1~~$605.0 million, or ~~13.7%~~13.5%, of our consolidated total liabilities, in each case as of ~~June~~September 30, 2020.

The following table provides information with respect to repurchases of the Company’s common stock pursuant to open market repurchases:

As of ~~June~~September 30, 2020, there was ~~$1,099.3~~$892.8 million of available authorization remaining under the ~~2018~~2019 Repurchase Program.

On ~~July 27,~~October 26, 2020, the Board of Directors declared a quarterly cash dividend of $0.78 per share for the three months ending September 30, 2020. ~~This reflects an increase of 14.7% over the quarterly cash dividend declared for the three months ended June 30, 2020.~~ The ~~third~~fourth quarter 2020 dividend is payable on ~~August 31,~~November 30, 2020 to shareholders of record as of the close of trading on ~~August 14,~~November 13, 2020.

Cash and cash equivalents were ~~$1,385.0~~$1,302.9 million and $1,506.6 million as of ~~June~~September 30, 2020 and December 31, 2019, respectively. We typically seek to maintain minimum cash balances globally of approximately $200.0 million to $250.0 million for general operating purposes but may maintain higher minimum cash balances while the COVID-19 pandemic continues to impact global economic markets. As of ~~June~~September 30, 2020 and December 31, 2019, ~~$336.0~~$411.0 million and $321.2 million, respectively, of the cash and cash equivalents were held by foreign subsidiaries. As a result of the 2017 Tax ~~Reform,~~Act, we can now more efficiently access a significant portion of our cash held outside of the U.S. in the short-term without being subject to U.S. income taxes. Repatriation of some foreign cash may still be subject to certain withholding taxes in local jurisdictions and other distribution restrictions. The global cash and cash equivalent balances that are maintained will be available to meet our global needs whether for general corporate purposes or other needs, including acquisitions or expansion of our products.

We believe that global cash flows from operations, together with existing cash and cash equivalents and funds available under our existing credit facility and our ability to access the debt and capital markets for additional funds, will continue to be sufficient to fund our global operating activities and cash commitments for investing and financing activities, such as material capital expenditures and share repurchases, for at least the next 12 months and for the foreseeable future thereafter. In addition, we expect that foreign cash flows from operations, together with existing cash and cash equivalents will continue to be sufficient to fund our foreign operating activities and cash commitments for investing activities, such as material capital expenditures, for at least the next 12 months and for the foreseeable future thereafter.

Cash flows from operating activities consist of net income adjusted for certain non-cash items and changes in assets and liabilities. Cash provided by operating activities was ~~$375.4~~$575.2 million and ~~$277.3~~$465.9 million for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, respectively. The year-over-year increase was primarily driven by higher cash collections from customers, ~~and the benefit of lower~~partially offset by higher payments for income taxes ~~partially offset by~~and higher interest payments. As a result of a provision within the Cares Act, we ~~have~~ elected to defer estimated payments for income taxes for the year ending December 31, 2020 that historically would have been paid in the six months ended June 30, 2020 into the month of July 2020.

Our primary uses of cash from operating activities are for the payment of cash compensation expenses, office rent, technology costs, market data costs, interest expenses and income taxes. Historically, the payment of cash for compensation and benefits is at its highest level in the first quarter when we pay discretionary employee compensation related to the previous fiscal year.

~~Cash flows from operating activities for the year ending December 31, 2020 are expected to decrease from those for the year ended December 31, 2019, in part, from the impact of the COVID-19 pandemic.~~

Cash used in investing activities was ~~$213.2~~$224.9 million for the ~~six~~nine months ended ~~June~~September 30, 2020 compared to ~~$20.5~~$35.3 million for the ~~six~~nine months ended ~~June~~September 30, 2019. The year-over-year change was primarily driven by the $190.8 million investment in Burgiss.

We expect to continue to invest in the business despite the COVID-19 pandemic, with cash flows for capital expenditures for the year ending December 31, 2020 expected to increase from the year ended December 31, 2019.

Cash used in financing activities was ~~$275.1~~$549.5 million for the ~~six~~nine months ended ~~June~~September 30, 2020 compared to ~~$391.5~~$450.3 million for the ~~six~~nine months ended ~~June~~September 30, 2019. The year-over-year change was primarily driven ~~by the impact of the 2031 Senior Notes and 2030 Senior Notes offerings in May 2020 and February 2020, respectively. This was partially offset~~ by the early redemptions of the 2025 Senior Notes and 2024 Senior Notes, as well as the impact of higher share repurchases. This was partially offset by the impact of the 2031 Senior Notes and 2030 Senior Notes offerings in May 2020 and February 2020, respectively.

We do not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

We are subject to foreign currency exchange fluctuation risk. Exchange rate movements can impact the U.S. dollar-reported value of our revenues, expenses, assets and liabilities denominated in non-U.S. dollar currencies or where the currency of such items is different than the functional currency of the entity where these items were recorded.

We generally invoice our clients in U.S. dollars; however, we invoice a portion of our clients in Euros, British pounds sterling, Japanese yen and a limited number of other non-U.S. dollar currencies. For the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, ~~13.9%~~14.0% and ~~14.0%~~13.6%, respectively, of our revenues are subject to foreign currency exchange rate risk and primarily includes clients billed in foreign currency as well as U.S. dollar exposures on non-U.S. dollar foreign operating entities. Of the ~~13.9%~~14.0% of non-U.S. dollar exposure for the ~~six~~nine months ended ~~June~~September 30, 2020, ~~39.7%~~40.4% was in Euros, ~~27.4%~~27.2% was in Japanese yen and ~~23.6%~~24.2% was in British pounds sterling. Of the ~~14.0%~~13.6% of non-U.S. dollar exposure for the ~~six~~nine months ended ~~June~~September 30, 2019, ~~41.2%~~41.0% was in Euros, ~~26.0%~~26.4% was in Japanese yen and ~~22.5%~~23.0% was in British pounds sterling.

Revenues from index-linked investment products represented ~~22.8% and 22.4%~~23.1% of operating revenues for both the ~~six~~nine months ended ~~June~~September 30, 2020 and ~~2019, respectively.~~2019. While a substantial portion of our fees for index-linked investment products are invoiced in U.S. dollars, the fees are based on the investment product’s assets, of which more than three-fifths are invested in securities denominated in currencies other than the U.S. dollar. Accordingly, declines in such other currencies against the U.S. dollar will decrease the fees payable to us under such licenses. In addition, declines in such currencies against the U.S. dollar could impact the attractiveness of such investment products resulting in net fund outflows, which would further reduce the fees payable under such licenses.

We are exposed to additional foreign currency risk in certain of our operating costs. Approximately ~~40.5%~~40.7% and ~~40.8%~~40.6% of our operating expenses for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, respectively, were denominated in foreign currencies, the significant majority of which were denominated in British pounds sterling, Indian rupees, Hungarian forints, Euros, Hong Kong dollars, Swiss francs, and Mexican pesos. Expenses incurred in foreign currency may increase as we expand our business outside the U.S.

We have certain monetary assets and liabilities denominated in currencies other than local functional amounts and when these balances are remeasured into their local functional currency, either a gain or a loss results from the change of the value of the functional currency as compared to the originating currencies. We manage foreign currency exchange rate risk, in part, through the use of derivative financial instruments comprised principally of forward contracts on foreign currency which are not designated as hedging instruments for accounting purposes. The objective of the derivative instruments is to minimize the impact on the income statement of the volatility of amounts denominated in certain foreign currencies. We recognized total foreign currency exchange ~~gains~~losses of ~~$1.4~~$1.0 million and ~~losses of $3.1~~$3.2 million for the ~~six~~nine months ended ~~June~~September 30, 2020 and 2019, respectively.

Our Chief Executive Officer and Chief Financial Officer have evaluated our disclosure controls and procedures, as defined in Rule 13a-15(e) or 15d-15(e) of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”), as of ~~June~~September 30, 2020, and have concluded that these disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time specified in the SEC’s rules and forms. These disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and the Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended ~~June~~September 30, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Various lawsuits, claims and proceedings have been or may be instituted or asserted against the Company in the ordinary course of business. While the amounts claimed could be substantial, the ultimate liability cannot now be determined because of the considerable uncertainties that exist. Therefore, it is possible that MSCI’s business, operating results, financial condition or cash flows in a particular period could be materially affected by certain contingencies. However, based on facts currently available, management believes that the disposition of matters that are currently pending or asserted will not, individually or in the aggregate, have a material effect on MSCI’s business, operating results, financial condition or cash flows.

There have been no material changes to the significant risk factors and uncertainties known to the Company and disclosed in the Company’s Form 10-K for the fiscal year ended December 31, 2019 and Form 10-Q for the period ended March 31, 2020 that, if they were to materialize or occur, would, individually or in the aggregate, have a material effect on MSCI’s business, operating results, financial condition or cash flows.

For a discussion of the risk factors affecting the Company, see “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for fiscal year 2019 and in Part II, Item 1A of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020.
