Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block]	'
	3. RECENT ACCOUNTING PRONOUNCEMENTS
	Accounting Standards or Updates Recently Adopted
	Balance Sheet Offsetting
	In December 2011, the FASB issued an accounting standard update requiring enhanced disclosures about certain financial instruments and derivative instruments that are offset in the balance sheet or that are subject to enforceable master netting arrangements or similar agreements. In January 2013, the FASB issued a clarifying accounting standard update, which limited the scope of the previous guidance to only derivatives, repurchase type agreements and securities borrowing and lending transactions. These accounting standard updates were effective for FactSet beginning in the first quarter of fiscal 2014. Other than the additional disclosure, the adoption of this accounting standard update did not have an impact on the Company’s consolidated financial statements.
	Indefinite-lived Intangible Assets
	In July 2012, the FASB issued an accounting standard update intended to simplify how an entity tests indefinite-lived intangible assets other than goodwill for impairment by providing entities with an option to perform a qualitative assessment to determine whether further impairment testing is necessary. This accounting standard update became effective for FactSet beginning in the first quarter of fiscal 2014 and did not have an impact on the Company’s consolidated financial statements.
	Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income
	In February 2013, the FASB issued an accounting standard update to require reclassification adjustments from other comprehensive income to be presented either in the financial statements or in the notes to the financial statements. This accounting standard update became effective for FactSet beginning in the first quarter of fiscal 2014 and the additional information has been disclosed.
	Cumulative Translation Adjustments
	In March 2013, the FASB issued an accounting standard update requiring an entity to release into net income the entire amount of a cumulative translation adjustment related to its investment in a foreign entity when as a parent it either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets within a foreign entity. This accounting standard update was adopted by FactSet beginning in the first quarter of fiscal 2014 and did not have an impact on the Company’s consolidated financial statements.
	Recent Accounting Standards or Updates Not Yet Effective
	Reporting Discontinued Operations
	In April 2014, the FASB issued an accounting standard update that changes the criteria for reporting discontinued operations. Under the accounting standard update, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has, or will have, a major effect on an entity's operations and financial results when either it qualifies as held for sale, disposed of by sale, or disposed of other than by sale. This accounting standard update will be effective for FactSet beginning in the first quarter of fiscal 2016. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.
	Revenue Recognition
	In May 2014, the FASB issued an accounting standard update which provides clarified principles for recognizing revenue arising from contracts with clients and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity recognizes revenue to depict the transfer of promised goods or services to clients in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the revenue model to contracts within its scope, an entity will identify the contract with a client, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when (or as) the entity satisfies a performance obligation. This accounting standard update will be effective for FactSet beginning in the first quarter of fiscal 2018. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.
	No other new accounting pronouncements issued or effective as of May 31, 2014 have had or are expected to have an impact on the Company’s consolidated financial statements.

Disclosure Text Block [Abstract]	'
Fair Value, Measurement Inputs, Disclosure [Text Block]	'
	4. FAIR VALUE MEASURES
	Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly transaction between market participants at the measurement date. In determining fair value, the use of various valuation methodologies, including market, income and cost approaches is permissible. The Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability.
	(a) Fair Value Hierarchy
	The accounting guidance for fair value measurements establishes a fair value hierarchy that requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value based on the reliability of inputs. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect their placement within the fair value hierarchy levels. FactSet has categorized its cash equivalents, investments and derivatives within the hierarchy as follows:
	Level 1 – applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. These Level 1 assets and liabilities include FactSet’s corporate money market funds that are classified as cash equivalents.
	Level 2 – applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. The Company’s certificates of deposit and derivative instruments are classified as Level 2.
	Level 3 – applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. There were no Level 3 assets or liabilities held by FactSet as of May 31, 2014 or August 31, 2013.
	(b) Assets and Liabilities Measured at Fair Value on a Recurring Basis
	The following tables shows by level within the fair value hierarchy the Company’s assets and liabilities that are measured at fair value on a recurring basis at May 31, 2014 and August 31, 2013 (in thousands):

	Total liabilities measured at fair value		$	0	$	7,740	$	0	$	7,740
		-1	The Company’s corporate money market funds are traded in an active market and the net asset value of each fund on the last day of the quarter is used to determine its fair value. As such, the Company’s corporate money market funds are classified as Level 1 and included in cash and cash equivalents on the consolidated balance sheet.
		-2	The Company’s certificates of deposit are held to maturity are not debt securities and are classified as Level 2. These certificates of deposit have original maturities greater than three months, but less than one year and, as such, are classified as investments (short-term) on the Company’s consolidated balance sheet.
		-3	The Company utilizes the income approach to measure fair value for its derivative instruments (foreign exchange forward contracts). The income approach uses pricing models that rely on market observable inputs such as spot, forward and interest rates, as well as credit default swap spreads and therefore are classified as Level 2.
	The Company did not have any transfers between Level 1 and Level 2 fair value measurements during the periods presented.
	Assets and liabilities measured at fair value on a recurring basis were presented on the Company’s Consolidated Balance Sheets at May 31, 2014 and August 31, 2013 as follows (in thousands):

	Total liabilities measured at fair value		$	0	$	7,740	$	0	$	7,740
	(c) Assets and Liabilities Measured at Fair Value on a Non-recurring Basis
	Certain assets, including goodwill and intangible assets, and liabilities, are measured at fair value on a non-recurring basis; that is, the assets and liabilities are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances such as when they are deemed to be other-than-temporarily impaired. The fair values of these non-financial assets and liabilities are determined based on valuation techniques using the best information available, and may include quoted market prices, market comparables, and discounted cash flow projections. An impairment charge is recorded when the cost exceeds its fair value, based upon the results of such valuations. During the three and nine months ended May 31, 2014, no fair value adjustments or material fair value measurements were required for the Company’s non-financial assets or liabilities.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Instruments and Hedging Activities Disclosure [Text Block]	'
	5. DERIVATIVE INSTRUMENTS
	Cash Flow Hedges
	FactSet conducts business outside the U.S. in several currencies including the British Pound Sterling, Euro, Japanese Yen, Indian Rupee and Philippine Peso. As such, it is exposed to movements in foreign currency exchange rates compared to the U.S. dollar. To manage the exposures related to the effects of foreign exchange rate fluctuations, the Company utilizes derivative instruments (foreign currency forward contracts). The Company’s primary objective in holding derivatives is to reduce the volatility of earnings and cash flows associated with changes in foreign currency. The Company does not enter into foreign exchange forward contracts for trading or speculative purposes. In designing a specific hedging approach, FactSet considered several factors, including offsetting exposures, significance of exposures, forecasting risk and potential effectiveness of the hedge. The gains and losses on foreign currency forward contracts offset the variability in operating expenses associated with currency movements. There was no discontinuance of cash flow hedges during the three and nine months ended May 31, 2014 and 2013, respectively, and as such, no corresponding gains or losses were reclassified into earnings. The changes in fair value for these foreign currency forward contracts are initially reported as a component of accumulated other comprehensive loss (“AOCL”) and subsequently reclassified into operating expenses when the hedged exposure affects earnings.
	As of May 31, 2014 FactSet maintained foreign currency forward contracts to hedge approximately 75% of its Indian Rupee exposure through the fourth quarter of fiscal 2016 and approximately 50% of its Philippines Peso exposure through the second quarter of fiscal 2015. At May 31, 2014, the notional principal and fair value of foreign exchange contracts to purchase Indian Rupees with U.S. dollars was Rs.2.8 billion and $1.1 million, respectively. At May 31, 2014, the notional principal and fair value of foreign exchange contracts to purchase Philippine Pesos with U.S. dollars was Php 408.1 million and $0.1 million, respectively.
	The following is a summary of all hedging positions and corresponding fair values (in thousands):
		Gross Notional Value								Fair Value Asset (Liability)
	Currency Hedged (in U.S. dollars)	31-May-14				31-Aug-13				31-May-14				31-Aug-13
	Indian Rupee	$	42,751			$	47,388			$	1,128			$	(7,693	)

	Total	$	51,951			$	69,524			$	1,242			$	(7,740	)
	Counterparty Credit Risk
	As a result of the use of derivative instruments, the Company is exposed to counterparty credit risk. FactSet has incorporated counterparty risk into the fair value of its derivative assets and its own credit risk into the value of the Company’s derivative liabilities. FactSet calculates credit risk from observable data related to credit default swaps (“CDS”) as quoted by publicly available information. Counterparty risk is represented by CDS spreads related to the senior secured debt of the respective bank with whom FactSet has executed these derivative transactions. Because CDS spread information is not available for FactSet, the Company’s credit risk is determined based on using a simple average of CDS spreads for peer companies. To mitigate counterparty credit risk, FactSet enters into contracts with large financial institutions. The Company regularly reviews its credit exposure balances as well as the creditworthiness of the counterparties. The Company does not expect any losses as a result of default of its counterparties.

	7. SEGMENT INFORMATION
	Operating segments are defined as components of an enterprise that engage in business activities from which it may earn revenues and incur expenses, whose operating results are regularly reviewed by the enterprise’s chief operating decision maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available. FactSet’s CODM is its Chief Executive Officer, who is responsible for making decisions about resources allocated amongst the operating segments based on actual results.
	FactSet’s operating segments are aligned with how the Company, including its CODM, manages the business and the demographic markets in which FactSet serves. The Company’s internal financial reporting structure is based on three segments; U.S., Europe and Asia Pacific. FactSet believes this alignment helps it better manage the business and view the markets the Company serves, which are centered on providing integrated global financial and economic information. Sales, consulting, data collection and software engineering are the primary functional groups within the U.S., Europe and Asia Pacific segments that provide global financial and economic information to investment managers, investment banks and other financial services professionals. The U.S. segment services finance professionals including financial institutions throughout the Americas, while the European and Asia Pacific segments service investment professionals located throughout Europe and Asia, respectively.
	The European segment is headquartered in London, England and maintains office locations in France, Germany, the Netherlands, Latvia, Sweden, Dubai and Italy. The Asia Pacific segment is headquartered in Tokyo, Japan with office locations in Hong Kong, Singapore, Australia and Mumbai, India. Segment revenues reflect direct sales to clients based in their respective geographic locations. There are no intersegment or intercompany sales of the FactSet service. Each segment records compensation, including stock-based compensation, amortization of intangible assets, depreciation of furniture and fixtures, amortization of leasehold improvements, communication costs, professional fees, rent expense, travel, marketing, office and other direct expenses. Expenditures associated with the Company’s data centers, third party data costs and corporate headquarters charges are recorded by the U.S. segment and are not allocated to the other segments. The content collection centers located in India and the Philippines benefit all of the Company’s operating segments and thus the expenses incurred at these locations are allocated to each segment based on a percentage of revenues. Of the total $287.3 million of goodwill reported by the Company at May 31, 2014, 63% was recorded in the U.S. segment, 36% in the European segment and the remaining 1% in the Asia Pacific segment.
	The following reflects the results of operations of the segments consistent with the Company’s management system. These results are used by management, both in evaluating the performance of, and in allocating resources to, each of the segments (in thousands).

	Revere Data
	On September 1, 2013, FactSet acquired the assets of Revere Data, LLC (“Revere”) to complement the Company's commitment to provide its clients with insightful content sets, for $15.3 million in cash. Revere classifies companies into a unique industry taxonomy and offers a database of supply chain relationships that helps investors identify companies’ interrelationships and mutual dependencies. As of the date of acquisition, Revere had annual subscriptions of $4.9 million. The opportunity for FactSet to offer this robust data to new and existing clients contributed to a purchase price in excess of fair value of the Revere net tangible and intangible assets. As a result, FactSet recorded goodwill in connection with this transaction.
	Allocation of the purchase price to the assets acquired and liabilities assumed was finalized during the second quarter of fiscal 2014. The total purchase price was allocated to Revere’s net tangible and intangible assets based upon their estimated fair value as of the date of acquisition.
	The final Revere purchase price of $15.3 million was allocated as follows (in thousands):
	Tangible assets acquired	$	544
	Amortizable intangible assets
	Data content		2,799
	Client relationships		827
	Non-compete agreements		162
	Trade name		293
	Goodwill		11,612
	Total assets acquired		16,237
	Liabilities assumed		(949	)
	Net assets acquired	$	15,288
	Intangible assets of $4.1 million have been allocated to amortizable intangible assets consisting of data content, amortized over five years using a straight-line amortization method; client relationships, amortized over seven years using an accelerated amortization method; non-compete agreements, amortized over two years using a straight-line amortization method; and trade name, amortized over four years using a straight-line amortization method.
	Goodwill totaling $11.6 million represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. Goodwill generated from the Revere acquisition is included in the U.S. segment and is deductible for income tax purposes. The results of the operations of Revere have been included in the Company’s Consolidated Statement of Income since the completion of the acquisition on September 1, 2013 and did not have a material impact on fiscal 2014 results. Pro forma information has not been presented because the effects of this acquisition were not material to the Company’s consolidated financial results.
	Matrix Data Limited
	During the second quarter of fiscal 2014, FactSet acquired Matrix Data Limited (“Matrix”) for a total purchase price of $31.8 million. Matrix’ primary line of business is a provider of intelligence to the UK financial services industry, covering market share of mutual fund distribution. Matrix has developed customer, channel and market benchmarking solutions that help clients optimize product distribution and improve marketing effectiveness to drive revenue growth. At the time of acquisition, Matrix had annual subscriptions of $7.3 million. The acquisition of Matrix will allow FactSet to expand its current U.S. advisor-sold investments and insurance products to the UK, with the potential to ultimately expand this coverage throughout continental Europe. The opportunity for FactSet to develop an international presence and complement its existing U.S. product offerings contributed to a purchase price in excess of fair value of the Matrix net tangible and intangible assets. As a result, FactSet recorded goodwill in connection with this transaction.
	Allocation of the purchase price to the assets acquired and liabilities assumed was finalized during the third quarter of fiscal 2014. There were no material adjustments between the preliminary and final allocation of purchase price. The total purchase price was allocated to Matrix’ net tangible and intangible assets based upon their estimated fair value as of the date of acquisition.
	The final Matrix purchase price of $31.8 million was allocated as follows (in thousands):
	Tangible assets acquired	$	7,459

	Goodwill		25,531
	Total assets acquired		41,739
	Liabilities assumed		(9,941	)
	Net assets acquired	$	31,798
	Intangible assets of $8.7 million have been allocated to amortizable intangible assets consisting of data content, amortized over four years using a straight-line amortization method; client relationships, amortized over eight years using an accelerated amortization method; software technology, amortized over five years using a straight-line amortization method; non-compete agreements, amortized over three years using a straight-line amortization method; and trade name, amortized over four years using a straight-line amortization method.
	Goodwill totaling $25.5 million represents the excess of the purchase price over the fair value of the net tangible and intangible assets acquired. Goodwill generated from the Matrix acquisition is included in the European segment and is deductible for income tax purposes. The results of the operations of Matrix have been included in the Company’s Consolidated Statement of Income since the completion of the acquisition and did not have a material impact on fiscal 2014 results. Pro forma information has not been presented because the effects of this acquisition were not material to the Company’s consolidated financial results.

	Balance at May 31, 2014	$	179,434	$	104,645	$	3,208		$	287,287
	Goodwill is not amortized as it has an estimated indefinite life. At least annually, the Company evaluates goodwill at the reporting unit level for potential impairment. Goodwill is tested for impairment based on the present value of discounted cash flows, and, if impaired, written down to fair value based on discounted cash flows. The Company has three reporting units, which are consistent with the operating segments reported because there is no discrete financial information available for the subsidiaries within each operating segment. The Company’s reporting units evaluated for potential impairment were the U.S., Europe and Asia Pacific, which reflects the level of internal reporting the Company uses to manage its business and operations. The Company performed an annual goodwill impairment test during the fourth quarter of fiscal years 2013 and 2012, which determined that there were no reporting units that were deemed at risk. The fair value of each of the Company’s reporting units significantly exceeded carrying value, thus there had been no impairment.

	FactSet’s identifiable intangible assets consist of acquired content databases, client relationships, software technology, non-compete agreements and trade names resulting from acquisitions, which have been fully integrated into the Company’s operations. The weighted average useful life of FactSet’s acquired identifiable intangible assets at May 31, 2014 was 11.1 years. The Company amortizes intangible assets over their estimated useful lives, which are evaluated quarterly to determine whether events and circumstances warrant a revision to the remaining period of amortization. There have been no changes to the estimate of the remaining useful lives during fiscal 2014. If indicators of impairment appear to exist, amortizable intangible assets are tested for impairment based on undiscounted cash flows, and, if impaired, written down to fair value based on discounted cash flows. No impairment of intangible assets has been identified during any of the periods presented. The intangible assets have no assigned residual values.

	13. EMPLOYEE STOCK OPTION AND RETIREMENT PLANS
	Stock Option Awards
	Options granted without performance conditions under the Company’s stock option plans expire either seven or ten years from the date of grant and the majority vest at a rate of 20% after the first year and 1.67% per month thereafter for years two through five. Options become vested and exercisable provided the employee continues employment with the Company through the applicable vesting date and remain exercisable until expiration or cancellation. The majority of options granted with performance conditions expire ten years from the date of grant and vest at a rate of 40% after the first two years and 1.67% per month thereafter for years three through five. Options are not transferable or assignable other than by will or the laws of descent and distribution. During the grantee’s lifetime, they may be exercised only by the grantee.
	During the first nine months of fiscal 2014, FactSet granted 391,478 stock options at a weighted average exercise price of $106.73 to existing employees of the Company.
	A summary of stock option activity is as follows (in thousands, except per share data):
		Number Outstanding			Weighted Average Exercise Price Per Share
	Balance at August 31, 2013		4,729		$	75.95
	Granted – non-performance-based		36			108.64
	Granted – performance-based		36			110.31
	Exercised		(136	)		59.38
	Forfeited		(10	)		79.22
	Balance at November 30, 2013		4,655		$	76.94
	Granted – non-performance-based		139			102.01
	Granted – performance-based		166			109.39
	Granted – non-employee Directors grant		14			107.65
	Exercised		(136	)		40.99
	Forfeited		(24	)		86.75
	Balance at February 28, 2014		4,814		$	79.85
	Exercised		(142	)		59.17
	Forfeited		(16	)		94.48
	Balance at May 31, 2014		4,656		$	80.42
	The total number of in-the-money options exercisable as of May 31, 2014 was 2.1 million with a weighted average exercise price of $66.34. As of August 31, 2013, 1.9 million in-the-money outstanding options were exercisable with a weighted average exercise price of $59.70. The aggregate intrinsic value of in-the-money stock options exercisable at May 31, 2014 and August 31, 2013 was $86.3 million and $82.1 million, respectively. Aggregate intrinsic value represents the difference between the Company’s closing stock price of $107.14 at May 31, 2014 and the exercise price multiplied by the number of options exercisable as of that date. The total pre-tax intrinsic value of stock options exercised during the three months ended May 31, 2014 and 2013 was $6.9 million and $31.4 million, respectively. The total pre-tax intrinsic value of stock options exercised during the nine months ended May 31, 2014 and 2013 was $22.9 million and $61.5 million, respectively.
	Performance-based Stock Options
	Performance-based stock options require management to make assumptions regarding the likelihood of achieving Company performance targets. The number of performance-based options that vest will be predicated on the Company achieving performance levels during the measurement period subsequent to the date of grant. Dependent on the financial performance levels attained by FactSet, a percentage of the performance-based stock options will vest to the grantees of those stock options. However, there is no current guarantee that such options will vest in whole or in part.
	November 2012 Annual Employee Performance-based Option Grant Review
	In November 2012, FactSet granted 1,011,510 performance-based employee stock options. The number of performance-based options that vest is based on the Company achieving performance levels for both organic annual subscription value and diluted earnings per share during the two fiscal years ended August 31, 2014. At May 31, 2014, FactSet estimated that 20% or 202,302 of the performance-based stock options would vest which results in unamortized stock-based compensation expense of $2.5 million to be recognized over the remaining vesting period of 3.4 years. However, a change in the actual financial performance levels achieved during the fourth quarter of 2014 could result in the following changes to the Company’s current estimate of the vesting percentage and related expense (in thousands):
	Vesting	Total Unamortized Stock-based			Cumulative Catch-up Adjustment*			Average Remaining Quarterly Expense to be Recognized
	Percentage	Compensation Expense at May 31, 2014
	0%	$	0		$	(2,265	)	$	0
	20%	$	2,483		$	0		$	182
	60%	$	7,449		$	4,530		$	545
	100%	$	12,415		$	9,060		$	908
	* Amounts represent the cumulative catch-up adjustment to be recorded if there was a change in the vesting percentage as of May 31, 2014.
	July 2012 Performance-based Option Grant Review
	In July 2012, FactSet granted 241,546 performance-based employee stock options, which are eligible to vest in 20% tranches depending upon future StreetAccount user growth through August 31, 2017. As a result of the accelerated expansion of StreetAccount users during the third quarter of fiscal 2014, FactSet determined that the second 20% tranche will vest by August 31, 2014. In addition, due to the accelerated third quarter growth and forecasted future usage growth, the Company estimated that the third 20% tranche will vest by August 31, 2017. This reflected a higher performance level than previously estimated and accordingly increased the number of options that will vest to a total 60%, which required FactSet to record a pre-tax stock-based compensation charge of $1.4 million in the third quarter of fiscal 2014. The change in estimate also results in unamortized stock-based compensation expense of $1.2 million to be recognized over the remaining vesting period of 3.3 years.
	A change, up or down, in the actual financial performance levels achieved by StreetAccount in future fiscal years could result in the following changes to the current estimate of the vesting percentage and related expense (in thousands):
	Vesting	Cumulative			Remaining Expense
	Percentage	Catch-up Adjustment*			to be Recognized
	Third 20%	$	(594	)	$	1,006
	Fourth 20%	$	736		$	2,055
	Fifth 20%	$	1,704		$	2,687
	* Amounts represent the cumulative catch-up adjustment to be recorded if there was a change in the vesting percentage as of May 31, 2014.
	Matrix and Revere Performance-based Option Grants
	In connection with the acquisitions of Matrix and Revere during fiscal 2014, FactSet granted 165,949 and 36,695 performance-based stock options, respectively. The performance-based options granted in connection with the acquisition of Matrix will vest only if ASV and operating margin targets related to the Matrix business are met during a five year measurement period ending December 23, 2018, and the option holders remain employed by FactSet. As of May 31, 2014 FactSet does not believe these targets are probable of being achieved, and as such, no stock-based compensation expense is expected to be realized in connection with these options. Of the 36,695 performance-based stock options granted in connection with the Revere acquisition, FactSet currently estimates that 18,553 options will vest based upon the achievement of certain ASV and operating margins during the measurement period ending August 31, 2015. This results in unamortized stock-based compensation expense of $0.5 million to be recognized over the remaining vesting period of 4.2 years.
	Restricted Stock and Stock Unit Awards
	The Company’s stock option and award plan permits the issuance of restricted stock and restricted stock units. Restricted stock awards are subject to continued employment over a specified period. During the first nine months of fiscal 2014, FactSet granted 204,124 restricted stock awards at a weighted average grant date fair value of $101.95 to employees of the Company.
	A summary of restricted stock award activity is as follows (in thousands, except per award data):
		Number Outstanding			Weighted Average Grant
					Date Fair Value Per Award
	Balance at August 31, 2013		358		$	80.43
	Granted (restricted stock and stock units)		162		$	102.27
	Vested		(63	)	$	83.49
	Canceled/forfeited		(2	)	$	69.27
	Balance at November 30, 2013		455		$	87.69
	Granted (restricted stock and stock units)		42		$	100.7
	Vested		(17	)	$	60.28

	Canceled/forfeited		(3	)	$	89.77
	Balance at May 31, 2014		418		$	89.34
	* Of the total 55,431 restricted stock awards that vested during the third quarter of fiscal 2014, 29,087 related to awards granted on April 14, 2011 at the grant date price of $103.30. These restricted stock awards cliff vested 100% after three years on April 14, 2014. The awards were amortized to expense over the vesting period using the straight-line attribution method. The remaining 26,344 restricted stock awards that vested during the third quarter were granted on April 8, 2013 and cliff vest 20% annually upon each anniversary date of the grant.
	November 2013 Employee Restricted Stock Award
On November 1, 2013, FactSet granted 153,972 restricted stock awards with a fair value of $102.22, which entitle the holder to shares of common stock as the awards vest over time. These restricted stock awards cliff vest 60% after three years (on November 1, 2016) and the remaining 40% after five years (on November 1, 2018). As of May 31, 2014 unamortized stock-based compensation expense of $12.0 million is to be amortized ratably to compensation expense over the remaining vesting period of 4.4 years.
Matrix and Revere Restricted Stock Units
In connection with the acquisitions of Matrix and Revere, FactSet granted 30,144 and 7,744 performance-based restricted stock units, respectively. The Matrix restricted stock units cliff vest 20% annually upon each anniversary date of the grant and as of May 31, 2014 unamortized stock-based compensation expense of $2.8 million is to be amortized ratably to compensation expense over the remaining vesting period of 4.6 years. Of the 7,744 performance-based restricted stock units granted in connection with the Revere acquisition, 3,872 are estimated to vest based upon management’s belief that certain of the ASV and operating margin targets will be achieved during the measurement period ending August 31, 2017. As of May 31, 2014 unamortized stock-based compensation of $0.3 million will be amortized to compensation expense over the remaining vesting period of 4.3 years. The remaining 3,872 performance-based restricted stock units granted in connection with the Revere acquisition are expected to be forfeited.
Other Restricted Stock Units
An additional 12,264 restricted stock awards were granted during the first nine months of fiscal 2014 to existing employees of FactSet. These restricted stock awards cliff vest 60% after three years, with the remaining 40% vesting on the fifth year anniversary date. As of May 31, 2014 unamortized stock-based compensation of $1.0 million will be amortized to compensation expense over the remaining vesting period of 4.7 years.

Employee Stock Purchase Plan
On December 16, 2008, the Company’s stockholders ratified the adoption of the FactSet Research Systems Inc. 2008 Employee Stock Purchase Plan (the “Purchase Plan”). A total of 500,000 shares have been reserved for issuance under the Purchase Plan. There is no expiration date for the Purchase Plan. Shares of FactSet common stock may be purchased by eligible employees under the Purchase Plan in three-month intervals at a purchase price equal to at least 85% of the lesser of the fair market value of the Company’s common stock on either the first day or the last day of each three-month offering period. Employee purchases may not exceed 10% of their gross compensation during an offering period.
During the three months ended May 31, 2014, employees purchased 18,068 shares at a weighted average price of $88.55 as compared to 16,739 shares at a weighted average price of $82.67 in the same period a year ago. During the nine months ended May 31, 2014, employees purchased 54,597 shares at a weighted average price of $88.33 as compared to 56,230 shares at a weighted average price of $79.77 in the same period a year ago. At May 31, 2014, 65,173 shares were reserved for future issuance under the Purchase Plan.
401(k) Plan
The Company established a 401(k) Plan (the “401(k) Plan”) in fiscal 1993. The 401(k) Plan is a defined contribution plan covering all full-time, U.S. employees of the Company and is subject to the provisions of the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code of 1986. Each year, participants may contribute up to 60% of their eligible annual compensation, subject to annual limitations established by the Internal Revenue Code. The Company matches up to 4% of employees’ earnings, capped at the IRS annual maximum. Company matching contributions are subject to a five year graduated vesting schedule. All full-time, U.S. employees are eligible for the matching contribution by the Company. The Company contributed $5.7 million and $5.5 million in matching contributions to employee 401(k) accounts during the nine months ended May 31, 2014 and 2013, respectively.

There was no stock-based compensation capitalized as of May 31, 2014 or August 31, 2013.
	Employee Stock Option Fair Value Determinations
	The Company utilizes the lattice-binomial option-pricing model (“binomial model”) to estimate the fair value of new employee stock option grants. The Company’s determination of fair value of stock option awards on the date of grant using the binomial model is affected by the Company’s stock price as well as assumptions regarding a number of variables. These variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards, interest rates, option forfeitures and employee stock option exercise behaviors.
	Fiscal 2014
		-	Q1 2014 – 35,508 non performance-based employee stock options and 36,695 performance-based employee stock options were granted at a weighted average exercise price of $109.49 and a weighted average estimated fair value of $31.78 per share.
		-	Q2 2014 – 138,902 non performance-based employee stock options and 165,949 performance-based employee stock options were granted at a weighted average exercise price of $106.03 and a weighted average estimated fair value of $29.14 per share.
		-	Q3 2014 - There were no employee stock options granted during the three months ended May 31, 2014.
	Fiscal 2013
		-	Q1 2013 – 635,308 non performance-based employee stock options and 1,011,510 performance-based employee stock options were granted at a weighted average exercise price of $92.22 and a weighted average estimated fair value of $26.87 per share.
		-	Q2 2013 – 9,367 non performance-based employee stock options were granted at a weighted average exercise price of $92.55 and a weighted average estimated fair value of $26.69 per share.
		-	Q3 2013 - There were no employee stock options granted during the three months ended May 31, 2013.
	The weighted average estimated fair value of employee stock options granted during fiscal 2014 and 2013 was determined using the binomial model with the following weighted average assumptions. There were no employee stock options granted during the three months ended May 31, 2014 and 2013.
			Nine Months Ended
			May 31,
			2014			2013
	Term structure of risk-free interest rate			0.01% - 2.61	%		0.16% - 1.91	%
	Expected life (in years)		7.6 – 7.8			7.6 – 7.8
	Term structure of volatility			23% - 33	%		24% - 33	%
	Dividend yield			1.35	%		1.3	%
	Weighted average estimated fair value		$	29.64		$	26.87
	Weighted average exercise price		$	106.69		$	92.22
	Fair value as a percentage of exercise price			27.8	%		29.1	%
	The risk-free interest rate assumption for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on a combination of historical volatility of the Company’s stock and implied volatilities of publicly traded options to buy FactSet common stock with contractual terms closest to the expected life of options granted to employees. The approach to utilize a mix of historical and implied volatility was based upon the availability of actively traded options on the Company’s stock and the Company’s assessment that a combination of implied volatility and historical volatility is best representative of future stock price trends. The Company uses historical data to estimate option exercises and employee termination within the valuation model. The dividend yield assumption is based on the Company’s history and expectation of dividend payouts. The expected life of employee stock options represents the weighted average period the stock options are expected to remain outstanding and is a derived output of the binomial model. The binomial model estimates employees exercise behavior is based on the option’s remaining vested life and the extent to which the option is in-the-money. The binomial model estimates the probability of exercise as a function of these two variables based on the entire history of exercises and cancellations of all past option grants made by the Company.
	Non-Employee Director Stock Option Fair Value Determinations
	The 2008 Non-Employee Directors’ Stock Option Plan (the “Directors’ Plan”) provides for the grant of share-based awards, including stock options, to non-employee directors of FactSet. A total of 250,000 shares of FactSet common stock have been reserved for issuance under the Directors’ Plan. The expiration date of the Directors’ Plan is December 1, 2018.
	The Company utilizes the Black-Scholes model to estimate the fair value of new non-employee Director stock option grants. The Company’s determination of fair value of share-based payment awards on the date of grant is affected by the Company’s stock price as well as assumptions regarding a number of variables. These variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards, interest rates, option forfeitures and employee stock option exercise behaviors.
	Fiscal 2014
	On January 15, 2014, FactSet granted 14,424 stock options to the Company’s non-employee Directors. All of the options granted on January 15, 2014 have a weighted average estimated fair value of $27.04 per share, using the Black-Scholes option-pricing model with the following weighted average assumptions:
	Risk-free interest rate			1.66	%
	Expected life (in years)			5.4
	Expected volatility			28.9	%
	Dividend yield			1.35	%
	Fiscal 2013
	On January 15, 2013, FactSet granted 18,781 stock options to the Company’s non-employee Directors at a weighted average estimated fair value of $24.23 per share, using the Black-Scholes option-pricing model with the following weighted average assumptions:
	Risk-free interest rate			0.89	%
	Expected life (in years)			5.4
	Expected volatility			32.3	%
	Dividend yield			1.3	%
	The risk-free interest rate assumption for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on the historical volatility of the Company’s stock. The Company uses historical data to estimate option exercises and non-employee director terminations within the valuation model. The dividend yield assumption is based on the Company’s history and expectation of dividend payouts.
	Restricted Stock Fair Value Determinations
	Restricted stock granted to employees entitle the holder to shares of common stock as the award vests over time, but not to dividends declared on the underlying shares while the restricted stock is unvested. The grant date fair value of restricted stock awards are measured by reducing the grant date price of FactSet’s common stock by the present value of the dividends expected to be paid on the underlying stock during the requisite service period, discounted at the appropriate risk-free interest rate.
	Employee Stock Purchase Plan Fair Value Determinations
	During the three months ended May 31, 2014, employees purchased 18,068 shares at a weighted average price of $88.55 as compared to 16,739 shares at a weighted average price of $82.67 in the same period a year ago. During the nine months ended May 31, 2014, employees purchased 54,597 shares at a weighted average price of $88.33 as compared to 56,230 shares at a weighted average price of $79.77 in the same period a year ago. Stock-based compensation expense recorded for the three months ended May 31, 2014 and 2013, relating to the employee stock purchase plan was $0.3 million, respectively.
	The Company uses the Black-Scholes model to calculate the estimated fair value for the employee stock purchase plan. The estimated fair value of employee stock purchase plan grants during the three months ended May 31, 2014 and 2013 were $17.81 and $16.15 per share, respectively, with the following assumptions:
			Three Months Ended
			May 31,
			2014			2013
	Risk-free interest rate			0.04	%		0.06	%
	Expected life (in months)			3			3
	Expected volatility			13.3	%		10.4	%
	Dividend yield			1.5	%		1.44	%
	The weighted average estimated fair value of employee stock purchase plan grants during the nine months ended May 31, 2014 and 2013 were $17.91 and $15.65 per share, respectively, with the following weighted average assumptions:
			Nine Months Ended
			May 31,
			2014			2013
	Risk-free interest rate			0.04	%		0.08	%
	Expected life (in months)			3			3
	Expected volatility			10.8	%		9.9	%
	Dividend yield			1.36	%		1.36	%
	Accuracy of Fair Value Estimates
	The Company is responsible for determining the assumptions used in estimating the fair value of its share-based payment awards. The Company’s determination of fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards, interest rates, option forfeiture rates and actual and projected employee stock option exercise behaviors. Option-pricing models were developed for use in estimating the value of traded options that have no vesting or hedging restrictions and are fully transferable.

	FactSet’s effective tax rate is based on recurring factors and nonrecurring events, including the taxation of foreign income. The Company’s effective tax rate will vary based on changes in levels of foreign income, as well as discrete and other nonrecurring events that may not be predictable. The effective tax rate was lower than the U.S. statutory rate of 35% for the three and nine months ended May 31, 2014 and 2013 due to foreign income, which is subject to lower statutory tax rates than in the U.S., benefits from foreign tax credits and the U.S. Federal R&D tax credit partially offset by additional state and local income taxes.

	A provision has not been made for additional U.S. Federal taxes as of May 31, 2014 as all undistributed earnings of foreign subsidiaries are considered to be invested indefinitely or will be repatriated free of additional tax. The amount of such undistributed earnings of these foreign subsidiaries included in consolidated retained earnings was immaterial at May 31, 2014 and August 31, 2013. As such, the unrecognized deferred tax liability on those undistributed earnings was immaterial. These earnings could become subject to additional tax if they are remitted as dividends, loaned to FactSet, or upon sale of the subsidiary’s stock.
	Unrecognized Tax Positions
	Applicable accounting guidance prescribes a comprehensive model for the financial statement recognition, measurement, classification and disclosure of uncertain tax positions that a company has taken or expects to take on a tax return. A company can recognize the financial effect of an income tax position only if it is more likely than not (greater than 50%) that the tax position will prevail upon tax examination, based solely on the technical merits of the tax position. Otherwise, no benefit or expense can be recognized in the consolidated financial statements. The tax benefits recognized are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. Additionally, companies are required to accrue interest and related penalties, if applicable, on all tax exposures for which reserves have been established consistent with jurisdictional tax laws.
	As of May 31, 2014, the Company had gross unrecognized tax benefits totaling $5.2 million, including $1.0 million of accrued interest, recorded as non-current taxes payable in the consolidated balance sheet. Unrecognized tax benefits represent tax positions taken on tax returns but not yet recognized in the consolidated financial statements. When applicable, the Company adjusts the previously recorded tax expense to reflect examination results when the position is effectively settled. The Company regularly engages in discussions and negotiations with tax authorities regarding tax matters in various jurisdictions. It is reasonably possible that certain federal, foreign, and state tax matters may be concluded in the next 12 months. However, FactSet has no reason to believe that such audits will result in the payment of additional taxes and/or penalties that would have a material adverse effect on the Company’s results of operations or financial position, beyond current estimates. Any changes in accounting estimates resulting from new developments with respect to uncertain tax positions will be recorded as appropriate. The Company does not currently anticipate that the total amounts of unrecognized tax benefits will significantly change within the next 12 months.
	The following table summarizes the changes in the balance of gross unrecognized tax benefits during the first nine months of fiscal 2014 (in thousands):
	Unrecognized income tax benefits at August 31, 2013	$	5,435
	Additions based on tax positions related to the current year		691
	Reductions for tax positions of prior years		(203	)
Reductions from settlements with taxing authorities		(766	)
Unrecognized income tax benefits at May 31, 2014	$	5,157
In the normal course of business, the Company’s tax filings are subject to audit by federal, state and foreign tax authorities. At May 31, 2014, the Company remained subject to examination in the following major tax jurisdictions for the tax years as indicated below:
Major Tax Jurisdictions	Open Tax Years

Commitments and Contingencies Disclosure [Abstract]	'
Commitments and Contingencies Disclosure [Text Block]	'
	16. COMMITMENTS AND CONTINGENCIES
	Commitments represent obligations, such as those for future purchases of goods or services that are not yet recorded on the balance sheet as liabilities. FactSet records liabilities for commitments when incurred (i.e., when the goods or services are received).
	Lease Commitments
	At May 31, 2014 the Company leases approximately 193,000 square feet of office space at its headquarters in Norwalk, Connecticut. In addition, FactSet leases office space for its U.S. reportable segment in New York, New York; Boston, Massachusetts; Chicago, Illinois; San Francisco, California; Austin, Texas; Jackson, Wyoming; Atlanta, Georgia; Tuscaloosa, Alabama; Newark, Ridgewood and Piscataway, New Jersey; Manchester, New Hampshire; Reston, Virginia, and Youngstown, Ohio. The Company’s European segment operates in leased office space in London, England; Paris and Avon, France; Amsterdam, the Netherlands; Frankfurt, Germany; Dubai, United Arab Emirates; Milan, Italy; Stockholm, Sweden; and Riga, Latvia. Office space in Tokyo, Japan; Hong Kong; Singapore; Mumbai, India; and Sydney, Australia are leased by FactSet for its Asia Pacific operating segment. The data content collection centers located in Hyderabad, India and Manila, the Philippines benefit all of the Companies operating segments. The leases expire on various dates through 2031. Total minimum rental payments associated with the leases are recorded as rent expense (a component of selling, general and administrative expenses) on a straight-line basis over the periods of the respective non-cancelable lease terms.
	During the three months ended May 31, 2014 and 2013, rent expense (including operating costs) for all operating leases amounted to $9.7 million and $8.8 million, respectively. Rent expense for all operating leases for the nine months of fiscal 2014 and 2013 amounted to $28.0 million and $27.2 million, respectively. Approximately $1.8 million of standby letters of credit have been issued during the ordinary course of business in connection with the Company’s current leased office space as of May 31, 2014. These standby letters of credit contain covenants that, among other things, require the Company to maintain minimum levels of consolidated net worth and certain leverage and fixed charge ratios. As of May 31, 2014, FactSet was in compliance with all covenants contained in the standby letters of credit.
	At May 31, 2014, FactSet leases approximately 836,000 square feet of office space, which the Company believes is adequate for its current needs and that additional space is available for lease to meet any future needs.
	At May 31, 2014, the Company’s lease commitments for office space provide for the following future minimum rental payments under non-cancelable operating leases with remaining terms in excess of one year (in thousands):
	Years Ended August 31,	Minimum Lease
		Payments
	2014 (remaining three months)	$	7,516
	2015		26,013
	2016		19,827
	2017		23,715
	2018		22,523
	Thereafter		112,511
	Total	$	212,105
	Included in the future minimum rental payments outlined above are $93.7 million in future rent payments related to a 15-year lease agreement executed in February 2014 to support the Company’s New York operations into calendar year 2031. During the third quarter of fiscal 2014, FactSet executed two leases for new office space in Mumbai, India and Austin, Texas, which resulted in additional future minimum rental payments totaling $2.4 million into calendar year 2019. Additional lease commitments assumed in connection with the Revere and Matrix acquisitions were immaterial, but did add approximately 11,000 square feet of office space.
	Purchase Commitments with Suppliers
	Purchase obligations represent payments due in future periods in respect of commitments to the Company’s various data vendors as well as commitments to purchase goods and services such as telecommunication and computer maintenance services. These purchase commitments are agreements that are enforceable and legally binding on FactSet and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and the approximate timing of the transaction. As of August 31, 2013, the Company had total purchase commitments of $50.2 million. There were no material changes in FactSet’s purchase commitments during fiscal 2014.
	Contingencies
	Legal Matters
	FactSet accrues non income-tax liabilities for contingencies when management believes that a loss is probable and the amounts can be reasonably estimated, while contingent gains are recognized only when realized. The Company is subject to legal proceedings, claims, and litigation arising in the ordinary course of business, including intellectual property litigation. Based on currently available information at May 31, 2014, FactSet’s management does not believe that the ultimate outcome of these unresolved matters against the Company, individually or in the aggregate, is likely to have a material adverse effect on the Company’s consolidated financial position, its results of operations or its cash flows.
	Income Taxes
	Uncertain income tax positions are accounted for in accordance with applicable accounting guidance (see Note 15). FactSet is currently under audit by tax authorities. The Company has reserved for potential adjustments to its provision for income taxes that may result from examinations by, or any negotiated settlements with, these tax authorities, and the Company believes that the final outcome of these examinations or settlements will not have a material effect on its results of operations. If events occur which indicate payment of these amounts is unnecessary, the reversal of the liabilities would result in the recognition of tax benefits in the period FactSet determines the liabilities are no longer necessary. If the Company’s estimates of the federal, state, and foreign income tax liabilities are less than the ultimate assessment, a further charge to expense would result.
	Indemnifications
	As permitted or required under Delaware law and to the maximum extent allowable under that law, FactSet has certain obligations to indemnify its current and former officers and directors for certain events or occurrences while the officer or director is, or was serving, at FactSet’s request in such capacity. These indemnification obligations are valid as long as the director or officer acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The maximum potential amount of future payments FactSet could be required to make under these indemnification obligations is unlimited; however, FactSet has a director and officer insurance policy that should mitigate FactSet's exposure and enables FactSet to recover a portion of any future amounts paid. The Company believes the estimated fair value, prior to consideration of any potential insurance recoveries, of these indemnification obligations is not material.
	Concentrations of Credit Risk
	Cash equivalents - Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may exceed the amount of insurance provided on such deposits. These deposits may be redeemed upon demand and are maintained with financial institutions with reputable credit and therefore bear minimal credit risk. The Company seeks to mitigate its credit risks by spreading such risks across multiple counterparties and monitoring the risk profiles of these counterparties.
	Accounts Receivable - Accounts receivable are unsecured and are derived from revenues earned from clients located around the globe. FactSet performs ongoing credit evaluations of its clients and does not require collateral from its clients. The Company maintains reserves for potential write-offs and these losses have historically been within expectations. No single client represented 10% or more of FactSet’s total revenues in any period presented. At May 31, 2014, the Company’s largest individual client accounted for 2% of total annual subscriptions and subscriptions from the ten largest clients did not surpass 15% of total annual subscriptions, consistent with August 31, 2013. At May 31, 2014 and August 31, 2013, the receivable reserve was $1.7 and $1.6 million, respectively.
	Derivative Instruments - As a result of the use of derivative instruments, the Company is exposed to counterparty credit risk. FactSet has incorporated counterparty risk into the fair value of its derivative assets and its own credit risk into the value of the Company’s derivative liabilities. FactSet calculates credit risk from observable data related to credit default swaps as quoted by publicly available information. Counterparty risk is represented by CDS spreads related to the senior secured debt of the respective bank with whom FactSet has executed these derivative transactions. Because CDS spread information is not available for FactSet, the Company’s credit risk is determined based on using a simple average of CDS spreads for peer companies as determined by FactSet. To mitigate counterparty credit risk, FactSet enters into contracts with large financial institutions and regularly reviews its credit exposure balances as well as the creditworthiness of the counterparties.

[1]	The Company's corporate money market funds are traded in an active market and the net asset value of each fund on the last day of the quarter is used to determine its fair value. As such, the Company's corporate money market funds are classified as Level 1 and included in cash and cash equivalents on the consolidated balance sheet.
[2]	The Company's certificates of deposit are held to maturity are not debt securities and are classified as Level 2. These certificates of deposit have original maturities greater than three months, but less than one year and, as such, are classified as investments (short-term) on the Company's consolidated balance sheet.
[3]	The Company utilizes the income approach to measure fair value for its derivative instruments (foreign exchange forward contracts). The income approach uses pricing models that rely on market observable inputs such as spot, forward and interest rates, as well as credit default swap spreads and therefore are classified as Level 2.
