Organization Consolidation And Presentation Of Financial Statements [Abstract]
Introduction and Basis of Presentation	1. INTRODUCTION AND BASIS OF PRESENTATION MSCI Inc., together with its wholly-owned subsidiaries (the “Company” or “MSCI”), offers content, applications and services to support the needs of institutional investors throughout their investment processes. The Company’s flagship products are its global equity indexes, custom indexes, factor indexes and ESG indexes; its analytics products, including multi-factor models, pricing models, methodologies for performance attribution, models for statistical analysis, and tools for portfolio optimization, back testing and stress testing; its ESG research and ratings; and its real estate benchmarks, indexes, business intelligence and analytics. Income (loss) from discontinued operations, net of income taxes in the Unaudited Condensed Consolidated Statement of Income for the six months ended June 30, 2015 represents the impact of an out-of-period income tax charge associated with tax obligations triggered upon the sale of Institutional Shareholder Services Inc. (“ISS”), which was completed on April 30, 2014. Basis of Presentation and Use of Estimates These unaudited condensed consolidated financial statements include the accounts of MSCI Inc. and its subsidiaries and include all adjustments of a normal, recurring nature necessary to present fairly the financial condition as of June 30, 2016 and December 31, 2015, the results of operations and comprehensive income for the three and six months ended June 30, 2016 and 2015 and cash flows for the six months ended June 30, 2016 and 2015. 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, 2015. The unaudited condensed consolidated financial statement information as of December 31, 2015 has been derived from the 2015 audited consolidated financial statements. 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 accounting principles generally accepted in the United States of America (“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, the allowance for doubtful accounts, impairment of long-lived assets, accrued compensation, income taxes 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. Concentrations No single customer represented 10.0% or more of the Company’s consolidated operating revenues for the six months ended June 30, 2016, while BlackRock, Inc. accounted for 10.5% of the Company’s consolidated operating revenues for the six months ended June 30, 2015. For the six months ended June 30, 2016 and 2015, BlackRock, Inc. accounted for 16.9% and 19.7% of the Index segment operating revenues, respectively. No single customer represented 10.0% or more of revenues within the Analytics and All Other segments for the six months ended June 30, 2016 and 2015.

Earnings Per Common Share

Earnings Per Share [Abstract]
Earnings Per Common Share	3. EARNINGS PER COMMON SHARE Basic earnings per share (“EPS”) is computed by dividing income available to MSCI common shareholders 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. There were no stock options or restricted stock units excluded from the calculation of diluted EPS for any period presented. The Company computes EPS using the two-class method and determines whether instruments granted in share-based payment transactions are participating securities. The following table presents the computation of basic and diluted EPS: Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 (in thousands, except per share data) Income from continuing operations, net of income taxes $ 66,957 $ 56,017 $ 127,324 $ 105,641 Income (loss) from discontinued operations, net of income taxes — — — (5,797 ) Net income $ 66,957 $ 56,017 $ 127,324 $ 99,844 Less: Allocations of earnings to unvested restricted stock units (1) — (18 ) — (32 ) Earnings available to MSCI common shareholders $ 66,957 $ 55,999 $ 127,324 $ 99,812 Basic weighted average common shares outstanding 96,412 112,143 97,918 112,330 Effect of dilutive securities: Stock options and restricted stock units 476 788 525 895 Diluted weighted average common shares outstanding 96,888 112,931 98,443 113,225 Earnings per basic common share from continuing operations $ 0.69 $ 0.50 $ 1.30 $ 0.94 Earnings per basic common share from discontinued operations — — — (0.05 ) Earnings per basic common share $ 0.69 $ 0.50 $ 1.30 $ 0.89 Earnings per diluted common share from continuing operations $ 0.69 $ 0.50 $ 1.29 $ 0.93 Earnings per diluted common share from discontinued operations — — — (0.05 ) Earnings per diluted common share $ 0.69 $ 0.50 $ 1.29 $ 0.88 (1) Restricted stock units granted to employees prior to 2013 and restricted stock units granted to independent directors of the Company prior to April 30, 2015 had a right to participate in all of the earnings of the Company in the computation of basic EPS and, therefore, these restricted stock units were not included as incremental shares in the diluted EPS computation.

At any time prior to August 15, 2020, the Company may redeem all or part of the 2025 Senior Notes upon not less than 30 nor more than 60 days’ prior notice at a redemption price equal to the sum of (i) 100% of the principal amount thereof, plus (ii) a make-whole premium as of the date of redemption, plus (iii) accrued and unpaid interest and additional interest, if any, thereon, to the date of redemption. In addition, the Company may redeem all or part of the 2025 Senior Notes, together with accrued and unpaid interest, on or after August 15, 2020, at redemption prices set forth in the indenture governing the 2025 Senior Notes. At any time prior to August 15, 2018, the Company may use the proceeds of certain equity offerings to redeem up to 35% of the aggregate principal amount of the 2025 Senior Notes, including any permitted additional notes, at a redemption price equal to 105.75% of the principal amount. Interest payments attributable to the 2024 Senior Notes are due on May 15 and November 15 of each year. The first interest payment was made on May 15, 2015. Interest payments attributable to the 2025 Senior Notes are due on February 15 and August 15 of each year. The first interest payment was made on February 16, 2016. Long-term debt at June 30, 2016 was $1,580.5 million, net of $19.5 million in deferred financing fees. Long-term debt at December 31, 2015 was $1,579.4 million, net of $20.6 million in deferred financing fees. In connection with the closing of the 2024 Senior Notes and 2025 Senior Notes offerings and entering into the 2014 Revolving Credit Agreement, the Company paid certain fees which, together with the existing fees related to prior credit facilities, are being amortized over the related lives. At June 30, 2016, $21.6 million of the deferred financing fees remain unamortized, $0.6 million of which is included in “Prepaid and other assets,” $1.5 million of which is included in “Other non-current assets” and $19.5 million of which is grouped and presented as part of “Long-term debt” on the Unaudited Condensed Consolidated Statement of Financial Condition. The Company amortized $0.7 million and $0.4 million of deferred financing fees in interest expense during the three months ended June 30, 2016 and 2015, respectively. The Company amortized $1.4 million and $0.9 million of deferred financing fees in interest expense during the six months ended June 30, 2016 and 2015, respectively. At June 30, 2016 and December 31, 2015, the fair market value of the Company’s debt obligations was $1,652.5 million and $1,638.0 million, respectively. The fair market value is determined in accordance with accounting standards related to the determination of fair value and represents Level 2 valuations, which are based on one or more quoted prices in markets that are not considered to be active or for which all significant inputs are observable, either directly or indirectly. The Company utilizes the market approach and obtains security pricing from a vendor who uses broker quotes and third-party pricing services to determine fair values. Derivatives and Hedging Activities. The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk primarily by managing the amount, sources and duration of its debt funding and the use of derivative financial instruments. Certain of the Company’s foreign operations expose the Company to fluctuations of foreign exchange rates. These fluctuations may impact the value of the Company’s cash receipts and payments in terms of the Company’s functional currency, the U.S. dollar. The Company enters into derivative financial instruments to protect the value or fix the amount of certain obligations in terms of its functional currency. Non-designated Hedges of Foreign Exchange Risk. Derivatives not designated as hedges are not speculative and are used to manage the Company’s economic exposure to foreign exchange rate movements but do not meet the strict hedge accounting requirements. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings. As of June 30, 2016, the Company had outstanding foreign currency forwards with a notional amount of $24.2 million that were not designated as hedges in qualifying hedging relationships. The following table presents the fair values of the Company’s derivative instruments and the location in which they are presented on the Company’s Unaudited Condensed Consolidated Statements of Financial Condition: Unaudited Condensed Consolidated Statements of As of (in thousands) Financial Condition Location June 30, 2016 December 31, 2015 Non-designated hedging instruments: Asset derivatives: Foreign exchange contracts Prepaid and other assets $ 1,367 $ 640 Liability derivatives: Foreign exchange contracts Other accrued liabilities $ (52 ) $ (2 ) The Company’s foreign exchange forward contracts represent Level 2 valuations, as they were valued using pricing models that took into account the contract terms as well as multiple observable inputs where applicable, such as prevailing spot rates and forward points.

Equity [Abstract]
Shareholders' Equity	7. SHAREHOLDERS’ EQUITY Return of capital . On February 4, 2014, the Board of Directors approved a stock repurchase program authorizing the purchase of up to $300.0 million worth of shares of MSCI’s common stock, which was increased to $850.0 million on September 17, 2014 (the “2014 Repurchase Program”). On October 14, 2015, the Company exhausted the $850.0 million share repurchase authorization under the 2014 Repurchase Program. On October 28, 2015, the Board of Directors approved a new stock repurchase program authorizing the purchase of up to $1.0 billion worth of shares of MSCI’s common stock (the “2015 Repurchase Program”). Share repurchases made pursuant to the 2015 Repurchase Program may take place in the open market or in privately negotiated transactions from time to time based on market and other conditions. This authorization may be modified, suspended or terminated by the Board of Directors at any time without prior notice. On June 2, 2015, the Company began purchasing shares of its common stock on the open market in accordance with SEC Rule 10b5-1. Through December 31, 2015, the Company paid $670.8 million to receive approximately 10.7 million shares pursuant to open market repurchases under the 2014 Repurchase Program and the 2015 Repurchase Program at an average purchase price of $62.63 per share. For the six months ended June 30, 2016, the Company received approximately 6.5 million shares at an average purchase price of $70.12 per share for a total value of $455.5 million under the 2015 Repurchase Program. Since 2012 and through June 30, 2016, approximately $1.9 billion has been returned to shareholders through share repurchases and payment of cash dividends. The following table presents cash dividends declared, deferred and distributed per common share for the periods indicated: Dividends (in thousands) Per Share Declared Distributed Deferred 2016 Three Months Ended March 30, $ 0.22 $ 22,046 $ 21,889 $ 157 Three Months Ended June 30, 0.22 21,588 21,391 197 Total $ 0.44 $ 43,634 $ 43,280 $ 354 2015 Three Months Ended March 30, $ 0.18 $ 20,424 $ 20,411 $ 13 Three Months Ended June 30, 0.18 20,443 20,441 2 Total $ 0.36 $ 40,867 $ 40,852 $ 15 Common Stock.

Income Tax Disclosure [Abstract]
Income Taxes	8. INCOME TAXES The Company’s provision for income taxes was $64.0 million and $59.4 million for the six months ended June 30, 2016 and 2015, respectively. These amounts reflect effective tax rates of 33.5% and 36.0% for the six months ended June 30, 2016 and 2015, respectively. The decrease in the effective tax rate was primarily driven by efforts to better align our tax profile with our global operating footprint. The Company is under examination by the IRS and other tax authorities in certain jurisdictions, including foreign jurisdictions, such as India, and states in which the Company has significant business operations, such as New York. The tax years currently under examination vary by jurisdiction but include years ranging from 2005 through 2015. As a result of having previously been a member of the Morgan Stanley consolidated group, the Company may have future settlements with Morgan Stanley related to the ultimate disposition of their New York State and New York City examination relating to the tax years 2007 and 2008 and their IRS examination relating to the tax years 2006 through 2008. The Company does not believe it has any material exposure to the New York State and New York City examinations. Additionally, the Company believes it has adequate reserves for any tax issues that may arise out of the IRS examination relating to the tax years 2006 through 2008 and therefore does not believe any related settlement with Morgan Stanley will have a material impact. 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. It is reasonably possible that significant changes in the balance of unrecognized tax benefits may occur within the next 12 months. At this time, however, it is not possible to reasonably estimate the expected change to the total amount of unrecognized tax benefits and the impact on the effective tax rate over the next 12 months.

Segment Reporting [Abstract]
Segment Information	9. SEGMENT INFORMATION ASC Subtopic 280-10, “Segment Reporting,” The CODM measures and evaluates reportable segments based on segment Adjusted EBITDA and key performance indicators, which include operating revenues and other items. The Company excludes the following items from segment Adjusted EBITDA: income (loss) from discontinued operations, net of income taxes, provision for income taxes, other expense (income), net, depreciation and amortization of property, equipment and leasehold improvements, amortization of intangible assets and certain transactions or adjustments that the CODM does not primarily 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. 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 allocated based upon various methodologies, including time estimates, headcount, sales targets, data center consumption and other relevant usage measures. Due to the integrated structure of our 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 revenue, 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 four operating segments: Index, Analytics, ESG and Real Estate. The Index operating segment is a provider of investment decision support tools, including equity indexes and equity index benchmarks. The products are used in many areas of the investment process, including portfolio construction and rebalancing, asset allocation, performance benchmarking and attribution, regulatory and client reporting and index-linked investment product creation. The Analytics operating segment consists of products and services used for portfolio construction, risk management and reporting. The products enable institutional investors to monitor, analyze and report on the risk and return of investments across a variety of asset classes. They are based on proprietary, integrated fundamental multi-factor risk models, value-at-risk methodologies, performance attribution frameworks and asset valuation models. In addition, the Analytics segment includes products that help investors value, model and hedge physical assets and derivatives across a number of market segments, including energy and commodity assets. The ESG operating segment offers products institutional investors use for assessing risks and opportunities arising from environmental, social and governance issues. ESG tools are used to evaluate both individual securities and investment portfolios. The Real Estate operating segment is a provider of real estate performance analysis for funds, investors, managers, lenders and occupiers. It provides index products and offers services that include research, reporting and benchmarking. The operating segments of ESG and Real Estate do not individually meet the segment reporting thresholds and have been combined and presented as part of the All Other segment for disclosure purposes. The following table presents operating revenue by the reportable segment for the periods indicated: Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 (in thousands) Operating revenues Index $ 152,117 $ 140,131 $ 296,730 $ 273,685 Analytics 112,393 107,570 222,656 214,415 All Other 26,086 22,879 50,038 45,249 Total $ 290,596 $ 270,580 $ 569,424 $ 533,349 The following table presents segment profitability and a reconciliation to net income for the periods indicated: Three Months Ended Six Months Ended June 30, June 30, 2016 2015 2016 2015 (in thousands) Index Adjusted EBITDA $ 106,518 $ 98,017 $ 206,567 $ 191,070 Analytics Adjusted EBITDA 33,302 21,264 63,662 35,344 All Other Adjusted EBITDA 6,207 (1,010 ) 8,947 (492 ) Total operating segment profitability 146,027 118,271 279,176 225,922 Amortization of intangible assets 11,943 11,695 23,783 23,397 Depreciation and amortization of property, equipment and leasehold improvements 8,393 8,065 16,561 15,272 Operating income 125,691 98,511 238,832 187,253 Other expense (income), net 25,147 11,095 47,511 22,177 Provision for income taxes 33,587 31,399 63,997 59,435 Income from continuing operations 66,957 56,017 127,324 105,641 Income (loss) from discontinued operations, net of income taxes — — — (5,797 ) Net income $ 66,957 $ 56,017 $ 127,324 $ 99,844 Revenue by geography is based on the shipping address of the ultimate customer utilizing the product.

Basis of Presentation and Use of Estimates	Basis of Presentation and Use of Estimates These unaudited condensed consolidated financial statements include the accounts of MSCI Inc. and its subsidiaries and include all adjustments of a normal, recurring nature necessary to present fairly the financial condition as of June 30, 2016 and December 31, 2015, the results of operations and comprehensive income for the three and six months ended June 30, 2016 and 2015 and cash flows for the six months ended June 30, 2016 and 2015. 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, 2015. The unaudited condensed consolidated financial statement information as of December 31, 2015 has been derived from the 2015 audited consolidated financial statements. 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 accounting principles generally accepted in the United States of America (“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, the allowance for doubtful accounts, impairment of long-lived assets, accrued compensation, income taxes 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.
Concentrations	Concentrations No single customer represented 10.0% or more of the Company’s consolidated operating revenues for the six months ended June 30, 2016, while BlackRock, Inc. accounted for 10.5% of the Company’s consolidated operating revenues for the six months ended June 30, 2015. For the six months ended June 30, 2016 and 2015, BlackRock, Inc. accounted for 16.9% and 19.7% of the Index segment operating revenues, respectively. No single customer represented 10.0% or more of revenues within the Analytics and All Other segments for the six months ended June 30, 2016 and 2015.
