Fair Value, Measurement Inputs, Disclosure [Text Block]	4. 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. 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.

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.

[1]	The Company utilizes the income approach to measure fair value for its derivative instruments (foreign currency 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 on 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) on the Consolidated Balance Sheets.
