Basis of Presentation and Significant Accounting Policies [Text Block]	2. FactSet conducts business globally and is managed on a geographic basis. The accompanying consolidated financial statements include the accounts of the Company and it s wholly owned subsidiaries. All intercompany activity and balances have been eliminated from the consolidated financial statements. The Company ’s consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles. The preparation of consolidated financial statements and related disclosures in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates have been made in areas that include allocation of purchase price to acquired assets and liabilities, stock-based compensation, income taxes, accrued compensation, valuation of goodwill, and useful lives and valuation of fixed and intangible assets. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from those estimates. The Company has evaluated s ubsequent events through the date that the financial statements were issued.

Notes to Financial Statements
Significant Accounting Policies [Text Block]	3. The significant accounting policies of the Company and its subsidiaries are summarized below. Revenue Recognition The majority of the Company’s revenues are derived from subscriptions to services such as workstations (also referred to as users), content and applications. The majority of clients are invoiced monthly to reflect the actual services provided. The remaining clients are invoiced quarterly, annually or biannually in advance. Subscription revenue is earned each month as the service is rendered to clients on a monthly basis. FactSet recognizes revenue when the client subscribes to FactSet services, the service has been rendered and earned during the month, the amount of the subscription is fixed or determinable based on established rates quoted on an annualized basis and collectability is reasonably assured. A provision for billing adjustments and cancellation of services is estimated and accounted for as a reduction to revenue, with a corresponding reduction to accounts receivable. Accounts Receivable and Deferred Fees Amounts that have been earned but not on the Consolidated Balance Sheets as Accounts receivable, net of reserves. Amounts invoiced in advance of client payments that are in excess of earned subscription revenues are reflected on the Consolidated Balance Sheet as Deferred fees. As of August 31, 2017, $5.3 2018 . The Company calculate s its receivable reserve through analyzing aged client receivables, reviewing the recent history of client receivable write-offs and understanding general market and economic conditions. In accordance with this policy, a receivable reserve of $2.7 $1.5 August 31, 2017 2016, Cost of Services Cost of services is comprised of compensation for Company employees within the content collection, consulting, product development, software and systems engineering groups in addition to data costs, computer maintenance and depreciation expenses, amortization of identifiable intangible assets, and client-related communication costs. Selling, General and Administrative Selling, general and administrative expenses include compensation for the sales and various other support and administrative departments in addition to travel and entertainment expenses, marketing costs, rent, amortization of leasehold improvements, depreciation of furniture and fixtures, office expenses, professional fees and other miscellaneous expenses. Research and Product Development Costs FactSet does not alue to clients. As such, research and product development costs relate to the salary and benefits for the Company’s product development, software engineering and technical support staff and, as such, these costs are expensed when incurred within cost of services as employee compensation. The Company expects to allocate a similar percentage of its workforce in future years in order to continue to develop new products and enhancements, respond quickly to market changes and meet the needs of its clients efficiently. FactSet incurred $215.0 2017, 2016 2015 . Earnings per Share Basic earnings per share (“ EPS”) is computed by dividing net income by the number of weighted average common shares outstanding during the period. Diluted EPS is computed by dividing net income by the number of weighted average common shares outstanding during the period increased by the dilutive effect of potential common shares outstanding during the period. The number of potential common shares outstanding has been determined in accordance with the treasury stock method to the extent they are dilutive. Common share equivalents consist of common shares issuable upon the exercise of outstanding share-based compensation awards, including employee stock options and restricted stock. Under the treasury stock method, the exercise price paid by the optionee, future stock-based compensation expense that the Company has not Comprehensive Income (Loss) The Company discloses comprehensive income (loss) in accordance with applicable standards for the reporting and display of comprehensive income (loss) in a set of financial statements. Comprehensive income (loss) is defined as the change in net assets of a business enterprise during a period from transactions generated from non-owner sources. It includes all changes in equity during a period except those resulting from investments by owners and distributions to owners. 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. 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 may 1 2. no 3 August 31, 2017 2016 .

Property, Equipment and Leasehold Improvements Property, equipment and leasehold improvements are stated at cost, less accumulated depreciation an d amortization. Computers and related equipment are depreciated on a straight-line basis over estimated useful lives of three seven not not The Company performs a test for impairment whenever events or changes in circumstances indicate that the carrying amount of an individual asset or asset group may not e recoverable. Should projected undiscounted future cash flows be less than the carrying amount of the asset or asset group, an impairment charge reducing the carrying amount to fair value is required. Fair value is determined based on the most appropriate valuation technique, including discounted cash flows. Goodwill The Company is required to test goodwill for impairment annually, or more frequently if impairment indicators occur. Goodwill is tested for impairment based on the present value of discount ed cash flows, and, if impaired, written down to fair value based on discounted cash flows. FactSet has three no fourth 2017, no Intangible Assets 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. Depending on the nature of the intangible asset, the identifiable intangible assets are amortized on either a straight-line or an accelerated basis using estimated useful lives ranging between two twenty no may not No Accrued Liabilities Accrued liabilities include estimates relating to employee compensation, operating expenses and tax liabilities. Approximately 15% ’s employee incentive compensation programs are discretionary. At the end of each fiscal year, FactSet conducts a final review of both Company and individual performance within each department to determine the amount of discretionary employee compensation. The Company also reviews compensation throughout the year to determine how overall performance tracks against management’s expectations. Management takes these and other factors, including historical performance, into account in reviewing accrued compensation estimates quarterly and adjusting accrual rates as appropriate. The amount of the variable employee compensation recorded within accrued compensation as of August 31, 2017 2016, $39.2 million and $38.2 Derivative Instruments FactSet conducts business outside the U.S. in several currencies includ ing the Indian Rupee, Philippine Peso, British Pound Sterling, Euro and Japanese Yen. As such, it is exposed to movements in foreign currency exchange rates compared to the U.S. dollar. The Company utilizes derivative instruments (foreign currency forward contracts) to manage the exposures related to the effects of foreign exchange rate fluctuations and reduce the volatility of earnings and cash flows associated with changes in foreign currency. The Company does not Foreign Currency Translation Certain wholly owned subsidiaries within the Europe an and Asia Pacific segments operate under a functional currency different from the U.S. dollar, such as the British Pound Sterling, Euro, Japanese Yen, Indian Rupee and Philippine Peso. The financial statements of these foreign subsidiaries are translated into U.S. dollars using period-end rates of exchange for assets and liabilities, and average rates for the period for revenues and expenses. Translation gains and losses that arise from translating assets, liabilities, revenues and expenses of foreign operations are recorded in AOCL as a component of stockholders’ equity. The accumulated foreign currency translation loss totaled $38.5 $67.3 August 31, 2017 2016, Income and Deferred Taxes Income tax expense is based on taxable income determined in accordance with current ly enacted laws and tax rates. Deferred income taxes are recorded for the temporary differences between the financial statement and tax bases of assets and liabilities using currently enacted tax rates. FactSet recognizes the financial effect of an income tax position only if it is more likely than not 50% no 50% August 31, 2017, $11.5 $1.5 Taxes Payable . Stock-Based Compensation Accounting guidance requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including stock opt ions, restricted stock and common shares acquired under employee stock purchases based on estimated fair values of the share awards that are scheduled to vest during the period. FactSet uses the straight-line attribution method for all awards with graded vesting features and service conditions only. Under this method, the amount of compensation expense that is recognized on any date is at least equal to the vested portion of the award on that date. For all stock-based awards with performance conditions, the graded vesting attribution method is used by the Company to determine the monthly stock-based compensation expense over the applicable vesting periods. As stock-based compensation expense recognized is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures are estimated based primarily on historical experience. Windfall tax benefits, defined as tax deductions that exceed recorded stock-based compensation, are classified as cash inflows from financing activities. Performance-based stock options require management to make assumptions regarding the likelihood of ach ieving Company performance targets on a quarterly basis. The number of performance-based options that vest will be predicated on the Company achieving certain performance levels. A change in the financial performance levels the Company achieves could result in changes to FactSet’s current estimate of the vesting percentage and related stock-based compensation. Treasury Stock The Company accounts for repurchased common stock under the cost method and includes such treasury stock as a component of its stockho lders’ equity. At the time treasury stock retirement is approved by FactSet’s Board of Directors, the Company’s accounting policy is to deduct its par value from common stock, reduce APIC by the amount recorded in APIC when the stock was originally issued and any remaining excess of cost as a deduction from retained earnings. Operating Leases The Company conducts all of its operations in leased facilities which have minimum lease obligations under non-cancelable operating leases. Certain of these leases co ntain rent escalations based on specified percentages. Most of the leases contain renewal options and require payments for taxes, insurance and maintenance. Rent expense is charged to operations as incurred except for escalating rents, which are charged to operations on a straight-line basis over the life of the lease. Lease incentives, relating to allowances provided by landlords, are amortized over the term of the lease as a reduction of rent expense. Costs associated with acquiring a subtenant, including broker commissions and tenant allowances, are amortized over the sublease term as a reduction of sublease income. Business Combinations The Company records acquisitions using the purchase method of accounting. All of the assets acquired, liabilities assu med, contractual contingencies and contingent consideration are recognized at their fair value on the acquisition date. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses and restructuring costs are recognized separately from the business combination and are expensed as incurred. Concentrations of Risk Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may may inancial 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.

There were no three Revenue Recognition In May 2014 July 2015, recognizing revenue arising from contracts with clients and supersede most current revenue recognition guidance, including industry-specific guidance.

These accounting standard updates will be effective for FactSet beginning in the first 2019, 2018 Balance Sheet Classification of Deferred Taxes In November 2015, will require an entity to present all deferred tax assets and deferred tax liabilities as non-current on the balance sheet.

This guidance also amends certain disclosure requirements associated with the fair value of financial instruments. This guidance will be effective for FactSet beginning in the first 2019. Leases In February 2016, The guidance introduces a lessee model that requires most leases to be reported on the balance sheet. The accounting standard update aligns many of the underlying principles of the new lessor model with those in the FASB’s new revenue recognition standard. The guidance also eliminates the requirement in current U.S. GAAP for an entity to use bright-line tests in determining lease classification. This accounting standard update will be effective for FactSet beginning in the first 2020, 2019 Share-Based Payments In March 2016, implifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flow.

Fair Value, Measurement Inputs, Disclosure [Text Block]	4. Fair value is defined as the price that would be received from selling an asset or pai d 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. 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 may may Level 1 - applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. These Level 1 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.

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 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 Non-Employee Director Stock Option Fair Value Determinations The 2008 on-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.

Concentration Risk Disclosure [Text Block]	20. Financial Risk Management Foreign Currency Exchange Risk The Company is exposed to changes in foreign currency exchange rates, which could affect its operating results, financial position and cash flows. The Company ’s primary foreign currency market exposures include the British Pound Sterling, Euro, Japanese Yen, Indian Rupee and Philippine Peso. To the extent that FactSet’s international activities recorded in local currencies increase in the future, its exposure to fluctuations in currency exchange rates will correspondingly increase. FactSet manages its exposure to foreign currency exchange risk through its regular operating and financing activities and, when appropriate, through the use of derivative financial instruments. These derivative financial instruments are utilized to hedge currency exposures as well as to reduce earnings volatility resulting from shifts in market rates. FactSet only enters into foreign currency forward contracts to manage foreign currency exposures. The fair market values of all the Company’s derivative contracts change with fluctuations in currency rates and are designed so that any changes in their values are offset by changes in the values of the underlying exposures. See Note 5, Derivative Instruments , for additional analysis of the Company’s foreign currency exchange rate risk.

Accounting Policies [Abstract]
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition The majority of the Company’s revenues are derived from subscriptions to services such as workstations (also referred to as users), content and applications. The majority of clients are invoiced monthly to reflect the actual services provided. The remaining clients are invoiced quarterly, annually or biannually in advance. Subscription revenue is earned each month as the service is rendered to clients on a monthly basis. FactSet recognizes revenue when the client subscribes to FactSet services, the service has been rendered and earned during the month, the amount of the subscription is fixed or determinable based on established rates quoted on an annualized basis and collectability is reasonably assured. A provision for billing adjustments and cancellation of services is estimated and accounted for as a reduction to revenue, with a corresponding reduction to accounts receivable.
Accounts Receivable and Deferred Fees [Policy Text Block]	Accounts Receivable and Deferred Fees Amounts that have been earned but not on the Consolidated Balance Sheets as Accounts receivable, net of reserves. Amounts invoiced in advance of client payments that are in excess of earned subscription revenues are reflected on the Consolidated Balance Sheet as Deferred fees. As of August 31, 2017, $5.3 2018 . The Company calculate s its receivable reserve through analyzing aged client receivables, reviewing the recent history of client receivable write-offs and understanding general market and economic conditions. In accordance with this policy, a receivable reserve of $2.7 $1.5 August 31, 2017 2016,
Cost of Sales, Policy [Policy Text Block]	Cost of Services Cost of services is comprised of compensation for Company employees within the content collection, consulting, product development, software and systems engineering groups in addition to data costs, computer maintenance and depreciation expenses, amortization of identifiable intangible assets, and client-related communication costs.
Selling, General and Administrative Expenses, Policy [Policy Text Block]	Selling, General and Administrative Selling, general and administrative expenses include compensation for the sales and various other support and administrative departments in addition to travel and entertainment expenses, marketing costs, rent, amortization of leasehold improvements, depreciation of furniture and fixtures, office expenses, professional fees and other miscellaneous expenses.
Research and Development Expense, Policy [Policy Text Block]	Research and Product Development Costs FactSet does not alue to clients. As such, research and product development costs relate to the salary and benefits for the Company’s product development, software engineering and technical support staff and, as such, these costs are expensed when incurred within cost of services as employee compensation. The Company expects to allocate a similar percentage of its workforce in future years in order to continue to develop new products and enhancements, respond quickly to market changes and meet the needs of its clients efficiently. FactSet incurred $215.0 2017, 2016 2015 .
Earnings Per Share, Policy [Policy Text Block]	Earnings per Share Basic earnings per share (“ EPS”) is computed by dividing net income by the number of weighted average common shares outstanding during the period. Diluted EPS is computed by dividing net income by the number of weighted average common shares outstanding during the period increased by the dilutive effect of potential common shares outstanding during the period. The number of potential common shares outstanding has been determined in accordance with the treasury stock method to the extent they are dilutive. Common share equivalents consist of common shares issuable upon the exercise of outstanding share-based compensation awards, including employee stock options and restricted stock. Under the treasury stock method, the exercise price paid by the optionee, future stock-based compensation expense that the Company has not
Comprehensive Income, Policy [Policy Text Block]	Comprehensive Income (Loss) The Company discloses comprehensive income (loss) in accordance with applicable standards for the reporting and display of comprehensive income (loss) in a set of financial statements. Comprehensive income (loss) is defined as the change in net assets of a business enterprise during a period from transactions generated from non-owner sources. It includes all changes in equity during a period except those resulting from investments by owners and distributions to owners.
Fair Value Measurement, Policy [Policy Text Block]	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. 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 may 1 2. no 3 August 31, 2017 2016 .

Computers and related equipment are depreciated on a straight-line basis over estimated useful lives of three seven not not The Company performs a test for impairment whenever events or changes in circumstances indicate that the carrying amount of an individual asset or asset group may not e recoverable. Should projected undiscounted future cash flows be less than the carrying amount of the asset or asset group, an impairment charge reducing the carrying amount to fair value is required. Fair value is determined based on the most appropriate valuation technique, including discounted cash flows.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill The Company is required to test goodwill for impairment annually, or more frequently if impairment indicators occur. Goodwill is tested for impairment based on the present value of discount ed cash flows, and, if impaired, written down to fair value based on discounted cash flows. FactSet has three no fourth 2017, no

Depending on the nature of the intangible asset, the identifiable intangible assets are amortized on either a straight-line or an accelerated basis using estimated useful lives ranging between two twenty no may not No
Accrued Liabilities [Policy Text Block]	Accrued Liabilities Accrued liabilities include estimates relating to employee compensation, operating expenses and tax liabilities. Approximately 15% ’s employee incentive compensation programs are discretionary. At the end of each fiscal year, FactSet conducts a final review of both Company and individual performance within each department to determine the amount of discretionary employee compensation. The Company also reviews compensation throughout the year to determine how overall performance tracks against management’s expectations. Management takes these and other factors, including historical performance, into account in reviewing accrued compensation estimates quarterly and adjusting accrual rates as appropriate. The amount of the variable employee compensation recorded within accrued compensation as of August 31, 2017 2016, $39.2 million and $38.2
Derivatives, Policy [Policy Text Block]	Derivative Instruments FactSet conducts business outside the U.S. in several currencies includ ing the Indian Rupee, Philippine Peso, British Pound Sterling, Euro and Japanese Yen. As such, it is exposed to movements in foreign currency exchange rates compared to the U.S. dollar. The Company utilizes derivative instruments (foreign currency forward contracts) to manage the exposures related to the effects of foreign exchange rate fluctuations and reduce the volatility of earnings and cash flows associated with changes in foreign currency. The Company does not
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translation Certain wholly owned subsidiaries within the Europe an and Asia Pacific segments operate under a functional currency different from the U.S. dollar, such as the British Pound Sterling, Euro, Japanese Yen, Indian Rupee and Philippine Peso. The financial statements of these foreign subsidiaries are translated into U.S. dollars using period-end rates of exchange for assets and liabilities, and average rates for the period for revenues and expenses. Translation gains and losses that arise from translating assets, liabilities, revenues and expenses of foreign operations are recorded in AOCL as a component of stockholders’ equity. The accumulated foreign currency translation loss totaled $38.5 $67.3 August 31, 2017 2016,
Income Tax, Policy [Policy Text Block]	Income and Deferred Taxes Income tax expense is based on taxable income determined in accordance with current ly enacted laws and tax rates. Deferred income taxes are recorded for the temporary differences between the financial statement and tax bases of assets and liabilities using currently enacted tax rates. FactSet recognizes the financial effect of an income tax position only if it is more likely than not 50% no 50% August 31, 2017, $11.5 $1.5 Taxes Payable .
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-Based Compensation Accounting guidance requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including stock opt ions, restricted stock and common shares acquired under employee stock purchases based on estimated fair values of the share awards that are scheduled to vest during the period. FactSet uses the straight-line attribution method for all awards with graded vesting features and service conditions only. Under this method, the amount of compensation expense that is recognized on any date is at least equal to the vested portion of the award on that date. For all stock-based awards with performance conditions, the graded vesting attribution method is used by the Company to determine the monthly stock-based compensation expense over the applicable vesting periods. As stock-based compensation expense recognized is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures are estimated based primarily on historical experience. Windfall tax benefits, defined as tax deductions that exceed recorded stock-based compensation, are classified as cash inflows from financing activities. Performance-based stock options require management to make assumptions regarding the likelihood of ach ieving Company performance targets on a quarterly basis. The number of performance-based options that vest will be predicated on the Company achieving certain performance levels. A change in the financial performance levels the Company achieves could result in changes to FactSet’s current estimate of the vesting percentage and related stock-based compensation.
Treasury Stock [Policy Text Block]	Treasury Stock The Company accounts for repurchased common stock under the cost method and includes such treasury stock as a component of its stockho lders’ equity. At the time treasury stock retirement is approved by FactSet’s Board of Directors, the Company’s accounting policy is to deduct its par value from common stock, reduce APIC by the amount recorded in APIC when the stock was originally issued and any remaining excess of cost as a deduction from retained earnings.
Lessee, Leases [Policy Text Block]	Operating Leases The Company conducts all of its operations in leased facilities which have minimum lease obligations under non-cancelable operating leases. Certain of these leases co ntain rent escalations based on specified percentages. Most of the leases contain renewal options and require payments for taxes, insurance and maintenance. Rent expense is charged to operations as incurred except for escalating rents, which are charged to operations on a straight-line basis over the life of the lease. Lease incentives, relating to allowances provided by landlords, are amortized over the term of the lease as a reduction of rent expense. Costs associated with acquiring a subtenant, including broker commissions and tenant allowances, are amortized over the sublease term as a reduction of sublease income.
Business Combinations Policy [Policy Text Block]	Business Combinations The Company records acquisitions using the purchase method of accounting. All of the assets acquired, liabilities assu med, contractual contingencies and contingent consideration are recognized at their fair value on the acquisition date. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Acquisition-related expenses and restructuring costs are recognized separately from the business combination and are expensed as incurred.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations of Risk Cash and cash equivalents are maintained with several financial institutions. Deposits held with banks may may inancial 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.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Standards or Updates Recently Adopted As of the beginning of fiscal 2017, (“FASB”) that were in effect. There were no three Revenue Recognition In May 2014 July 2015, recognizing revenue arising from contracts with clients and supersede 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. These accounting standard updates will be effective for FactSet beginning in the first 2019, 2018 Balance Sheet Classification of Deferred Taxes In November 2015, will require an entity to present all deferred tax assets and deferred tax liabilities as non-current on the balance sheet.

[1]	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.
[2]	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 within the Consolidated Balance Sheets.
[3]	The Company's mutual funds have a fair value based on the fair value of the underlying investments held by the mutual funds allocated to each share of the mutual fund using a net asset value approach. The fair value of the underlying investments is based on observable inputs. As such, the Company’s mutual funds are classified as Level 2 and are classified as investments (short-term) on the Consolidated Balance Sheets.
[4]	The Company's certificates of deposit held for investment 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) within the Consolidated Balance Sheets.
