The fair values of these financial assets have been classified as Level 1, 2 or 3 within the fair value hierarchy as described in the accounting standards for fair value measurements. Level 1 — Fair value based on quoted prices in active markets for identical assets or liabilities. Level 2 — Fair value based on inputs other than Level 1 inputs that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Fair value based on unobservable inputs that are supported by little or no market activity and such inputs are significant to the fair value of the assets or liabilities. The following table represents the Company’s fair value hierarchy for its financial assets (cash equivalents and investments) measured at fair value on a recurring basis as of June 30, 2015 and December 31, 2014 (in thousands): As of June 30, 2015 Level 1 Level 2 Level 3 Total Money market funds (1) $ 852 $ — $ — $ 852 Corporate obligations — 60,677 — 60,677 Total $ 852 $ 60,677 $ — $ 61,529 As of December 31, 2014 Level 1 Level 2 Level 3 Total Money market funds (1) $ 1,794 $ — $ — $ 1,794 Corporate obligations — 54,885 — 54,885 Total $ 1,794 $ 54,885 $ — $ 56,679 (1) Included in cash and cash equivalents. Level 2 assets consist of the Company’s entire portfolio of corporate bonds. Level 2 assets have been initially valued at the transaction price and subsequently valued, at the end of each reporting period, typically utilizing third party pricing services or other market observable data. The pricing services utilize industry standard valuation methods, including both income and market based approaches and observable market inputs to determine value. These observable market inputs include reportable trades, benchmark yields, credit spreads, broker/dealer quotes, bids, offers, current spot rates and other industry and economic events.

Investments Debt And Equity Securities [Abstract]
Non-Marketable Investments	Note 4 — Non-Marketable Investments At June 30, 2015 and December 31, 2014, the carrying value of the Company’s non-marketable investments, which were composed primarily of interests in technology-related private equity funds, was $3.7 million and $3.8 million, respectively, and is included in other assets in the Consolidated Balance Sheets. One of the Company’s investments, with a book value of $0.6 million and $0.7 million at June 30, 2015 and December 31, 2014, respectively, is being accounted for using the cost method and, accordingly, is valued at cost unless an other-than-temporary impairment in its value occurs. The other investments are being accounted for using the equity method as the investments are limited partnerships and the Company has an ownership interest in excess of 5% and, accordingly, the Company records its share of the investee’s operating results each period. Gains and losses from non-marketable investments were insignificant during the three and six months ended June 30, 2015 and 2014, and are included in gains (losses) on investments, net in the Consolidated Statements of Income. During the six months ended June 30, 2015 and 2014, gross distributions of $0.1 million and $1.4 million, respectively, were received from the funds.

Reorganization

Reorganization	6 Months Ended

Restructuring And Related Activities [Abstract]
Reorganization	Note 5 — Reorganization In the first quarter of 2015, the Company implemented a reduction in its workforce of approximately 4% of its employees across various geographies and functions, in order to reallocate investment in 2015 to planned sales expansion and to delivery areas seeing the greatest client demand. Overall the Company expects to increase its headcount by 5% to 7% at the end of 2015 compared to 2014 levels. The Company recorded $(0.2) million and $3.2 million of severance and related costs for this action during the three and six months ended June 30, 2015. In addition, the Company incurred $0.3 million during the three months ended June 30, 2015 primarily for a non-cash charge for the liquidation of a small non-U.S. subsidiary. The costs under this plan are expected to be substantially paid by the end of 2015. During 2014 the Company incurred $1.8 million of severance and related costs for the termination of approximately 1% of its employees across various geographies and functions primarily to realign resources due to the Company’s new organizational structure put in place in late 2013. Approximately $0.8 million of the costs were recognized in the three months ended March 31, 2014 and approximately $1.0 million were recognized in the three months ended June 30, 2014. The following table rolls forward the activity in the reorganization accrual for the six months ended June 30, 2015 (in thousands): Workforce Subsidiary Reduction Liquidation Total Accrual at December 31, 2014 $ 118 $ — $ 118 Additions 3,173 332 3,505 Cash payments (2,768 ) — (2,768 ) Non-cash charge — (318 ) (318 ) Accrual at June 30, 2015 $ 523 $ 14 $ 537

Earnings Per Share [Abstract]
Net Income Per Common Share	Note 6 — Net Income Per Common Share Basic net income per common share is computed by dividing net income by the basic weighted average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing net income by the diluted weighted average number of common shares and common equivalent shares outstanding during the period. The weighted average number of common equivalent shares outstanding has been determined in accordance with the treasury-stock method. Common equivalent shares consist of common stock issuable on the exercise of outstanding options and vesting of restricted stock units when dilutive. Basic and diluted weighted average common shares are as follows (in thousands): Three Months Ended Six Months Ended June 30, June 30, 2015 2014 2015 2014 Basic weighted average common shares outstanding 18,007 18,757 18,033 19,184 Weighted average common equivalent shares 261 287 281 295 Diluted weighted average common shares outstanding 18,268 19,044 18,314 19,479 Options excluded from diluted weighted average share calculation as effect would have been anti-dilutive 1,012 602 852 582

In the six months ended June 30, 2014, the Company declared and paid dividends of $6.1 million consisting of a $0.16 per share dividend in each of the first two quarters of 2014. In July 2015, the Company declared a dividend of $0.17 per share payable on September 16, 2015 to shareholders of record as of September 2, 2015. Treasury Stock As of June 30, 2015 Forrester’s Board of Directors had authorized an aggregate $435.0 million to purchase common stock under its stock repurchase program, including $25.0 million authorized in February 2015. In July 2015, the Board of Directors authorized an additional $25.0 million to be repurchased under the Company’s stock repurchase program. The shares repurchased may be used, among other things, in connection with Forrester’s employee and director equity incentive and purchase plans. In the three and six months ended June 30, 2015, the Company repurchased approximately 0.2 million shares and 0.3 million shares, respectively, of common stock at an aggregate cost of approximately $6.1 million and $11.8 million, respectively. In the three and six months ended June 30, 2014, the Company repurchased approximately 0.7 million shares and 1.5 million shares, respectively, of common stock at an aggregate cost of approximately $25.2 million and $54.9 million, respectively. From the inception of the program through June 30, 2015, Forrester repurchased approximately 14.7 million shares of common stock at an aggregate cost of approximately $414.0 million.

Income Tax Disclosure [Abstract]
Income Taxes	Note 8 — Income Taxes Forrester provides for income taxes on an interim basis according to management’s estimate of the effective tax rate expected to be applicable for the full fiscal year. Certain items such as changes in tax rates and tax benefits related to disqualifying dispositions of incentive stock options are treated as discrete items and are recorded in the period in which they arise. Income tax expense for the six months ended June 30, 2015 was $4.0 million resulting in an effective tax rate of 42.1% for the period. Income tax expense for the six months ended June 30, 2014 was $3.0 million resulting in an effective tax rate of 41.3% for the period. The increase in the effective tax rate for the six months ended June 30, 2015 as compared to the prior year period is primarily due to a $0.3 million loss on the liquidation of a foreign subsidiary in the 2015 period for which a tax benefit could not be recognized, partially offset by a $0.2 million expense in the 2014 period for a U.S. state audit that did not recur in 2015.

The transition was essentially complete at the end of 2014 such that the vast majority of project consulting will be delivered by the project consulting organization in 2015. The Product segment includes the costs of the product management organization that is responsible for product pricing and packaging and the launch of new products. In addition, this segment includes the costs of the Company’s data, Forrester Leadership Boards and events organizations. Revenue in this segment includes all revenue for the Company (including RoleView) except for revenue from advisory services and project consulting services that are delivered by personnel in the Research and Project Consulting segments. The Project Consulting segment includes the costs of the consultants that deliver the Company’s project consulting services. During 2013 the Company began to hire dedicated consultants to transition the delivery of project consulting services from research personnel (included in the Research segment) to the new Project Consulting segment. Revenue in this segment includes the project consulting revenue delivered by the consultants in this segment. The Company evaluates reportable segment performance and allocates resources based on segment revenues and expenses. Segment expenses include the direct expenses of each segment organization and exclude selling and marketing expenses, general and administrative expenses, stock-based compensation expense, depreciation expense, adjustments to incentive bonus compensation from target amounts, amortization of intangible assets, reorganization costs, other income and gains (losses) on investments.

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Pronouncements	Note 10 — Recent Accounting Pronouncements In May, 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-09, Revenue from Contracts with Customers, which supersedes all existing revenue recognition requirements, including most industry-specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. The new standard will be effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, with early adoption permitted for the first interim period within annual reporting periods beginning after December 15, 2016.
