NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — INTERIM CONSOLIDATED FINANCIAL STATEMENTS

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for reporting on Form 10-Q. Accordingly, certain information and footnote disclosures required for complete financial statements are not included herein. It is recommended that these financial statements be read in conjunction with the consolidated financial statements and related notes that appear in the Annual Report of Forrester Research, Inc. (“Forrester”) as reported on Form 10-K for the year ended December 31, 2004. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the financial position, results of operations, and cash flows as of the dates and for the periods presented have been included. The results of operations for the three months ended March 31, 2005 may not be indicative of the results that may be expected for the year ended December 31, 2005, or any other period.

Stock-Based Compensation

Statement of Financial Accounting Standards (“SFAS”) No. 123, “Accounting for Stock-Based Compensation”, and SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure”, requires the measurement of the fair value of stock options or warrants to be included in the statement of income or disclosed in the notes to financial statements. Forrester has determined it will continue to account for stock-based compensation for employees under Accounting Principles Board Opinion (“APB”) No. 25 and elect the disclosure-only alternative under SFAS No. 123. There is no compensation expense related to option grants reflected in the accompanying financial statements.

If compensation cost for Forrester’s stock option plans had been determined using the fair value method prescribed in SFAS No. 123, net income (loss) for the three months ended March 31, 2005 and 2004 would have been approximately as follows (in thousands, except per share data):

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 ending December 31.

NOTE 2 — INTANGIBLE ASSETS

A summary of Forrester’s amortizable intangible assets as of March 31, 2005 is as follows:

6

Amortization expense related to identifiable intangible assets was approximately $1,123,000 and $2,344,000 during the three months ended March 31, 2005 and 2004, respectively. Estimated amortization expense related to identifiable intangible assets that will continue to be amortized is as follows:

NOTE 3 — REORGANIZATIONS

In November 2003, Forrester acquired the assets of GigaGroup S.A. (“GigaGroup”). In January 2004, Forrester announced a reduction of its workforce by approximately 15 positions in connection with the integration of GigaGroup’s operations. As a result, Forrester recorded an initial reorganization charge of $1,957,000 during the three months ended March 31, 2004. Approximately 53% of the terminated employees had been members of the sales force, while 27% and 20% had held administrative and research roles, respectively. The charge consisted primarily of severance and related benefit costs, and other payments for professional services incurred in connection with the reorganization. During the three-months ended June 30, 2004 and December 31, 2004, Forrester provided for additional severance and related benefits costs of $240,000 and $313,000, respectively.

In connection with the integration of GigaGroup’s operations, Forrester vacated and subleased office space in San Francisco, Amsterdam and London during the three-months ended June 30, 2004. As a result of these vacancies and related subleases, Forrester recorded reorganization charges of approximately $4,693,000 related to the excess of contractual lease commitments over the contracted sublease revenue and $1,861,000 for the write-off of related leasehold improvements and furniture and fixtures.

The activity related to the January 2004 reorganization during the three months ended March 31, 2005 is as follows:

The accrued costs related to the January 2004 reorganization are expected to be paid in the following periods:

In connection with prior reorganizations of its workforce, Forrester has consolidated its office space. As a result of these consolidations, Forrester has aggregate accrued facility consolidation costs of $441,000 as of March 31, 2005. The activity related to these costs during the three months ended March 31, 2005 is as follows:

7

     These accrued facility costs are expected to be paid in the following periods:

NOTE 4 – NET INCOME (LOSS) PER COMMON SHARE

Basic net income per common share for the three months ended March 31, 2005 and basic and diluted net loss per common share for the three months ended March 31, 2004 were computed by dividing the net income (loss) by the basic weighted average number of common shares outstanding during the period. Diluted net income per common share for the three months ended March 31, 2005 was computed by dividing net income by the diluted weighted average number of common 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 stock equivalents consist of common stock issuable on the exercise of outstanding options when dilutive. A reconciliation of basic to diluted weighted average shares outstanding is as follows:

During the three-month periods ended March 31, 2005 and 2004, approximately 3,242,000 and 5,022,000 stock options, respectively, were excluded from the calculation of diluted weighted average shares outstanding as the effect would have been anti-dilutive.

NOTE 5 – COMPREHENSIVE INCOME (LOSS)

The components of total comprehensive income (loss) for the three month periods ended March 31, 2005 and 2004 are as follows:

NOTE 6 — MARKETABLE INVESTMENT

As of March 31, 2004, Forrester held an approximately 1.1% ownership interest in Greenfield Online, Inc. (“Greenfield”), an Internet-based market research firm. This investment was accounted for as a cost basis investment and valued at approximately $267,000 as of March 31, 2004. In July 2004, Greenfield (NASDAQ: SRVY) completed an initial public offering in which Forrester’s ownership interest was converted to approximately 136,000 shares of common stock. Upon consummation of the offering, Forrester received a conversion payment of approximately $463,000, and participated in the offering by selling approximately 21,000 shares of common stock for which net proceeds of approximately $256,000 were received. In December 2004, Greenfield completed a secondary offering in which Forrester participated and sold an additional 26,000 shares of common stock, receiving net proceeds of approximately $445,000. Upon expiration of the 90 day lock-up agreement in March 2005, Forrester sold the remainder of its holdings, approximately 89,000 shares of common stock, received net proceeds of approximately $1.7 million and recognized a gain of approximately $1.5 million related to the sale of these shares.

NOTE 7 — NON-MARKETABLE INVESTMENTS

8

In June 2000, Forrester committed to invest $20.0 million in two technology-related private equity investment funds with capital contributions required to be funded over a period of up to five years. During the three months ended March 31, 2005 and 2004, Forrester contributed approximately $150,000 and $963,000 to these investment funds, respectively, resulting in total cumulative contributions of approximately $18.0 million to date. One of these investments is being accounted for using the cost method and, accordingly, is valued at cost unless an other than temporary impairment in its value occurs or the investment is liquidated. The other investment is being accounted for using the equity method. During the three months ended March 31, 2005, distributions of $367,000 were recorded and resulted in a gain of $180,000 in the consolidated statement of income. During the three months ended March 31, 2005 and 2004, there were no impairments recorded. During the three months ended March 31, 2005 and 2004, fund management charges of approximately $84,000 were included in other income, net for each period in the consolidated statements of income, bringing the total cumulative fund management charges paid by Forrester to approximately $2.0 million as of March 31, 2005. Fund management charges are recorded as a reduction of the investments’ carrying value.

Forrester has adopted a cash bonus plan to pay bonuses, after the return of invested capital, measured by the proceeds of a portion of its share of net profits from these investments, if any, to certain key employees, subject to the terms and conditions of the plan. The payment of such bonuses would result in compensation expense with respect to the amounts so paid. To date, no bonuses have been paid under this plan. The principal purposes of this cash bonus plan was to retain key employees by allowing them to participate in a portion of the potential return from Forrester’s technology-related investments if they remained employed by the Company. The plan was established at a time when technology and internet companies were growing significantly, and providing incentives to retain key employees during that time was important.

The timing of the recognition of future gains or losses from these investment funds is beyond Forrester’s control. As a result, it is not possible to predict when Forrester will recognize such gains or losses, if Forrester will award cash bonuses based on the net profit from such investments, or when Forrester will incur compensation expense in connection with the payment of such bonuses. If the investment funds realize large gains or losses on their investments, Forrester could experience significant variations in its quarterly results unrelated to its business operations. These variations could be due to significant gains or losses or to significant compensation expenses. While gains may offset compensation expenses in a particular quarter, there can be no assurance that related gains and compensation expenses will occur in the same quarters.

NOTE 8 — STOCK REPURCHASE

In October 2001, Forrester announced a program authorizing the repurchase of up to $50 million of its common stock. The shares repurchased may be used, among other things, in connection with Forrester’s employee stock option and stock purchase plans and for potential acquisitions. In February 2005, the Board of Directors authorized the repurchase of up to an additional $50.0 million of common stock (“stock repurchase program”). During the three months ended March 31, 2005, Forrester repurchased 309,000 shares of common stock at an aggregate cost of approximately $4.8 million. As of March 31, 2005, Forrester had repurchased approximately 3,354,000 shares of common stock at an aggregate cost of approximately $54.8 million.

NOTE 9 – OPERATING SEGMENT AND ENTERPRISE WIDE REPORTING

During 2004, Forrester viewed its operations within the following three operating groups (“Operating Groups”): (i) North America, (ii) Europe and, (iii) World Markets which includes Asia, Middle East, Africa, and Latin America. Effective January 1, 2005, Forrester reorganized the operating groups as follows (i) Americas, (ii) Europe, Middle East and Africa (EMEA) and (iii) Asia Pacific. All of the Operating Groups generate revenues through sales of the same research and advisory and other service offerings. Each of the Operating Groups is composed of sales forces responsible for clients located in such Operating Group’s region and research personnel focused primarily on issues generally more relevant to clients in that region. Forrester evaluates reportable segment performance and allocates resources based on direct margin. Direct margin, as presented below, is defined as operating income excluding certain selling and marketing expenses, general and administrative expenses, depreciation expense, amortization of intangibles and reorganization charges. The accounting policies used by the reportable segments are the same as those used by Forrester.

Forrester does not identify or allocate assets, including capital expenditures, by operating segment. Accordingly, assets are not being reported by segment because the information is not available by segment and is not reviewed in the evaluation of performance or making decisions in the allocation of resources.

9

The following tables present information about reportable segments. Segment information for the three months ended March 31, 2004 has been restated to conform to the current year’s presentation.

Net revenues by geographic client location and as a percentage of total revenues are as follows:

NOTE 10 — RECENT ACCOUNTING PRONOUNCEMENTS

In December 2004, the Financial Accounting Standards Board (FASB) revised SFAS No. 123 (SFAS No. 123-R) which requires the measurement of the cost of employee services received in exchange for an award of an equity instrument based on the grant-date fair value of the award. The measured cost is to be recognized over the period during which an employee is required to provide service in exchange for the award, usually the vesting period. The provisions of SFAS No. 123-R are effective for all employee equity awards granted and to any unvested awards outstanding as of January 1, 2006. Retrospective application is permitted. The adoption of this statement is expected to have a material adverse impact on the company’s results of operations. The company is currently assessing the transition method it will use upon adoption.

10

In December 2004, the FASB issued SFAS No. 153, “Exchanges of Nonmonetary Assets,” which eliminates the exception of fair value measurement for nonmonetary exchanges of similar productive assets in existing accounting literature and replaces it with an exception for exchanges that do not have commercial substance. SFAS No. 153 specifies that a nonmonetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange. The provisions of SFAS No. 153 are effective for nonmonetary asset exchanges occurring in fiscal periods beginning after June 15, 2005. Adoption of this statement is not expected to have a material impact on the company’s financial position or results of operations.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “expects,” “believes,” “anticipates,” “intends,” “plans,” “estimates,” or similar expressions are intended to identify these forward-looking statements. These statements include, but are not limited to, statements about the potential success of WholeView 2 and other product offerings, the ability to achieve all of the anticipated benefits from the acquisition of Giga Information Group, the amount of the charge and any cost savings related to reductions in force and associated actions, and our ability to achieve success as the economy improves. These statements are based on our current plans and expectations and involve risks and uncertainties that could cause actual future activities and results of operations to be materially different from those set forth in the forward-looking statements. Important factors that could cause actual future activities and results to differ include, among others, our ability to anticipate business and economic conditions, market trends, competition, the ability to attract and retain professional staff, possible variations in our quarterly operating results, risks associated with our ability to offer new products and services, the actual amount of the charge and any cost savings related to reductions in force and associated actions, and our dependence on renewals of our membership-based research services and on key personnel. We undertake no obligation to update publicly any forward-looking statements, whether as a result of new information, future events, or otherwise.

We are a leading independent emerging-technology research firm that conducts research and analysis on the impact of emerging technologies on business, consumers, and society. We provide our clients with an integrated perspective on technology and business, which we call WholeView 2. This approach provides companies with the strategies, data, and product evaluations they need to win customers, identify new markets, and gain competitive operational advantages. Our products and services primarily are targeted to benefit the senior management, business strategists, and marketing and technology professionals at companies with revenues of $1 billion-plus who use our prescriptive, executable research to understand and capitalize on business models and emerging technologies.

We derive revenues from memberships to our research product offerings and from our advisory services and events available through what we refer to as Research, Data, Consulting, and Community offerings. We offer contracts for our research products that are typically renewable annually and payable in advance. Research revenues are recognized as revenue ratably over the term of the contract. Accordingly, a substantial portion of our billings are initially recorded as deferred revenue. Clients purchase advisory services offered through our Data, Consulting and Community products and services to supplement their memberships to our research. Billings attributable to advisory services are initially recorded as deferred revenue and are recognized as revenue when performed. Event billings are also initially recorded as deferred revenue and are recognized as revenue upon completion of each event. Consequently, changes in the number and value of client contracts, both net decreases as well as net increases, impact our revenues and other results over a period of several months.

Our primary operating expenses consist of cost of services and fulfillment, selling and marketing expenses, general and administrative expenses, depreciation and amortization of intangible assets. Cost of services and fulfillment represents the costs associated with the production and delivery of our products and services, and it includes the costs of salaries, bonuses, and related benefits for research personnel and all associated editorial, travel, and support services. Selling and marketing expenses include salaries, employee benefits, travel expenses, promotional costs, sales commissions, and other costs incurred in marketing and selling our products and services. General and administrative expenses include the costs of the technology, operations, finance, and strategy groups and our other administrative functions. Overhead costs are allocated over these categories according to the number of employees in each group. Amortization of intangible assets represents the cost of amortizing acquired intangible assets such as customer base, research content and trademarks.

14

Agreement value, client retention, dollar retention and enrichment are metrics we believe are important to understanding our business. We believe that the “agreement value” of contracts to purchase research and advisory services provides a significant measure of our business volume. We calculate agreement value as the total revenues recognizable from all research and advisory service contracts in force at a given time, without regard to how much revenue has already been recognized. No single client accounted for more than 3% of agreement value at March 31, 2005. We calculate client retention as the number of client companies who renewed with memberships as a percentage of those that would have expired. We calculate dollar retention as a percentage of the dollar value of all client membership contracts renewed during the most recent twelve month fiscal period to the total dollar value of all client membership contracts that expired during the period. We calculate enrichment as a percentage of the dollar value of client membership contracts renewed during the period to the dollar value of the corresponding expiring contracts. Client retention, dollar retention, and enrichment are not necessarily indicative of the rate of future retention of our revenue base. A summary of our key metrics is as follows:

The increase in agreement value from 2004 to 2005 is primarily due to increases in average contract sizes and in the number of clients. The average contract for annual memberships for research only at March 31, 2005 was approximately $40,300, an increase of 5% from $38,300 at March 31, 2004. The average contract for an annual membership for research which also included advisory services at March 31, 2005 was approximately $88,800, an increase of 2% from $87,200 at March 31, 2004. Client retention, dollar retention and enrichment increases in 2005 reflect an improving economic environment.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Management’s discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our policies and estimates, including but not limited to, those related to our revenue recognition, allowance for doubtful accounts, non-marketable investments, goodwill and other intangible assets and income taxes. Management bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We consider the following accounting policies to be those that require that most subjective judgment or those most important to the portrayal of our financial condition and results of operations. If actual results differ significantly from management’s estimates and projections, there could be a material effect on our financial statements. This is not a comprehensive list of all of our accounting policies. In many cases, the accounting treatment of a particular transaction is specifically dictated by generally accepted accounting principles, with no need for management’s judgment in their application. There are also areas in which management’s judgment in selecting any available alternative would not produce a materially different result. For further discussion of the application of these and our other accounting policies, see Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Notes to Consolidated Financial Statements in our December 31, 2004 Annual Report on Form 10-K for the year ended December 31, 2004, previously filed with the SEC.

13

•	REVENUE RECOGNITION. We generate revenues from licensing research, performing advisory services, and hosting events. We execute contracts that govern the terms and conditions of each arrangement. Revenues from contracts that contain multiple deliverables are allocated among the separate units based on their relative fair values, the estimate of which requires us to make estimates of such fair values. The amount of revenue recognized is limited to the amount that is not contingent on future performance conditions. Research service revenues are recognized ratably over the term of the agreement. Advisory service revenues are recognized during the period in which the services are performed. Events revenues are recognized upon completion of the events. While our historical business practice has been to offer membership contracts with a non-cancelable term, we do from time to time, in response to competitive conditions, offer clients the right to cancel their membership contracts prior to the end of the contract term. For these cancelable contracts that can be terminated during the contract term, any refund would be issued on a pro-rata basis only. Reimbursed out of pocket expenses are recorded as advisory revenue. Furthermore, our revenue recognition determines the timing of commission expenses that are deferred and expensed to operations as the related revenue is recognized. We evaluate the recoverability of deferred commissions at each balance sheet date. As of March 31, 2005, deferred revenues and deferred commissions totaled $73.0 million and $6.7 million, respectively.
•	ALLOWANCE FOR DOUBTFUL ACCOUNTS. We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make contractually obligated payments that totaled approximately $956,000 as of March 31, 2005. Management specifically analyzes accounts receivable and historical bad debts, customer concentrations, current economic trends, and changes in our customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required, and if the financial condition of our customers were to improve, the allowances may be reduced accordingly.
•	NON-MARKETABLE INVESTMENTS. We hold minority interests in technology-related companies and equity investment funds that totaled approximately $13.3 million as of March 31, 2005. These investments are in companies that are not publicly traded, and, therefore, because no established market for these securities exists, the estimate of the fair value of our investments requires significant judgment. We have a policy in place to review the fair value of our investments on a regular basis to evaluate the carrying value of the investments in these companies which consists primarily of reviewing the investee’s revenue and earnings trends relative to predefined milestones and overall business prospects. We record impairment charges when we believe that an investment has experienced a decline in value that is other than temporary. During the three months ended March 31, 2005, we have no investments that have experienced a decline in value which we believe is permanent or temporary and accordingly no impairment charges have been recorded. Future adverse changes in market conditions or poor operating results of underlying investments could result in losses or an inability to recover the carrying value of the investments that may not be reflected in an investment’s current carrying value, thereby possibly requiring an impairment charge in the future.
•	GOODWILL AND OTHER INTANGIBLE ASSETS. At March 31, 2005, we had goodwill of approximately $53.2 million and identified intangible assets with finite lives related to our acquisitions of approximately $6.0 million. SFAS No. 142, Goodwill and Other Intangible Assets, requires that goodwill and intangible assets with indefinite lives no longer be amortized but instead be measured for impairment at least annually or whenever events indicate that there may be an impairment. In order to determine if an impairment exists, we obtain an independent appraisal which determines if the carrying amount of the reporting unit exceeds the fair value. The estimates of the reporting unit’s fair value are based on market conditions and operational performance. Absent an event that indicates a specific impairment may exist, we have selected November 30th as the date of performing the annual goodwill impairment test. As of March 31, 2005, we believe that the carrying value of our goodwill is not impaired. Future events could cause us to conclude that impairment indicators exist and that goodwill associated with our acquired businesses are impaired. Any resulting impairment loss could have a material adverse impact on our financial condition and results of operations.
	Intangible assets with finite lives are valued according to the future cash flows they are estimated to produce. These assigned values are amortized on an accelerated basis which matches the periods those cash flows are estimated to be produced. We continually evaluate whether events or circumstances have occurred that indicate that the estimated remaining useful life of our intangible assets may warrant revision or that the carrying value of these assets may be impaired. To compute whether assets have been impaired, the estimated undiscounted future cash flows for the estimated remaining useful life of the assets are

14

	compared to the carrying value. To the extent that the future cash flows are less than the carrying value, the assets are written down to the estimated fair value of the asset.
•	INCOME TAXES. We have deferred tax assets related to temporary differences between the financial statement and tax bases of assets and liabilities as well as operating loss carryforwards (primarily from stock option exercises and the acquisition of Giga) that totaled approximately $43.2 million as of March 31, 2005. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible and the carryforwards expire. Although realization is not assured, based upon the level of our historical taxable income and projections for our future taxable income over the periods during which the deferred tax assets are deductible and the carryforwards expire, management believes it is more likely than not that we will realize the benefits of these deductible differences. The amount of the deferred tax asset considered realizable, however, could be reduced if estimates of future taxable income during the carry-forward periods are incorrect.

RESULTS OF OPERATIONS

The following table sets forth selected financial data as a percentage of total revenues for the periods indicated:

THREE MONTHS ENDED MARCH 31, 2005 AND MARCH 31, 2004

REVENUES.

15

The increase in total revenues as well as the increase in the number of clients is primarily attributable to improving economic conditions and to the effects of foreign currency translation which resulted in approximately a 1% positive effect on revenues in the three months ended March 31, 2005. No single client company accounted for more than 3% of revenues during the three months ended March 31, 2005 or 2004.

Research services revenues as a percentage of total revenues declined from 72% in the three months ended March 31, 2004 to 69% in the three months ended March 31, 2005 as customer demand is shifting towards advisory services. The increase in advisory services and other revenues is primarily attributable to increased demand for advisory services as well as an increase in events revenues resulting from an increase in the number of events held and from event sponsorships by third parties.

The decrease in international revenues in dollars and as a percentage of revenue is primarily attributable to business growing faster in the United States than in Europe and Asia. International revenues decreased 2% to $10.5 million in the three months ended March 31, 2005 from $10.7 million in the three months ended March 31, 2004.

COST OF SERVICS AND FULFILLMENT.

The increase in cost of services and fulfillment is primarily attributable to increased compensation expense resulting from an increase in average research headcount and annual compensation costs as well as to increased survey costs.

SELLING AND MARKETING.

The increase in selling and marketing expenses is primarily attributable to increased compensation expense resulting from an increase in average headcount and annual increases in compensation costs as well as to increased professional fees related to the Forrester magazine, the first issue of which was published in February 2005.

GENERAL AND ADMINISTRATIVE.

16

The increase in general and administrative expenses is primarily attributable to increased compensation expense resulting from an increase in average headcount and annual increases in compensation costs.

DEPRECIATION. Depreciation expense decreased 13% to $874,000 in the three months ended March 31, 2005 from $1.0 million in the three months ended March 31, 2004. The decrease is primarily attributable to computer and software assets purchased prior to 2002 becoming fully depreciated and to the write-off of certain depreciable assets in connection with office vacancies.

AMORTIZATION OF INTANGIBLE ASSETS. Amortization of intangible assets decreased to $1.1 million in the three months ended March 31, 2005 from $2.3 million in the three months ended March 31, 2004. This decrease in amortization expense is primarily attributable to the accelerated method we are using to amortize our acquired intangible assets according to the expected cash flows to be received from these assets. Specifically, research content and registered trademarks that were acquired in connection with the Giga acquisition in 2003 were fully amortized by the end of 2004.

OTHER INCOME, NET. Other income, net, consisting primarily of interest income, decreased 9% to $750,000 during the three months ended March 31, 2005 from $826,000 million during the three months ended March 31, 2004. The decrease is primarily due to declines in interest income resulting from lower returns on invested capital.

REALIZED GAINS ON SALES OF SECURITIES. In the three months ended March 31, 2005, we sold the remaining total of approximately 89,000 shares of Greenfield Online, Inc., received net proceeds of approximately $1.7 million, and recognized a gain of approximately $1.5 million related to these sales. Net gains on distributions from non-marketable investments totaled approximately $180,000 during the three months ended March 31, 2005.

REORGANIZATION COSTS. Reorganization costs in the three months ended March 31, 2004 consisted primarily of severance and related benefits costs in connection with the elimination of approximately 15 positions in January 2004.

PROVISION FOR INCOME TAXES. During the three months ended March 31, 2005, we recorded an income tax provision of $1.8 million, which reflected an effective tax rate of 39%. During the three months ended March 31, 2004, we recorded an income tax benefit of $130,000 reflecting an effective tax rate of 33.5%. The increase in our effective tax rate for fiscal year 2005 resulted primarily from our tax-exempt investment income comprising a smaller percentage of our estimated total pre-tax income in 2005 as compared to 2004.

LIQUIDITY AND CAPITAL RESOURCES

We have financed our operations primarily through funds generated from operations. Memberships for research services, which constituted approximately 69% of our revenues during the three months ended March 31, 2005, are annually renewable and are generally payable in advance. We generated cash from operating activities of $11.4 million and $9.5 million during the three months ended March 31, 2005 and 2004, respectively. The increase in cash provided from operations is primarily attributable to the increase in our income from operations and the collection of accounts receivable.

During the three months ended March 31, 2005, we used $127,000 of cash from investing activities, consisting primarily of $1.2 million received from net sales of marketable securities, offset by $1.6 million for capital expenditures. We regularly invest excess funds in short-and intermediate-term interest-bearing obligations of investment grade.

In June 2000, we committed to invest $20.0 million in two private equity investment funds over a period of up to five years. As of March 31, 2005, we had contributed approximately $18.0 million to the funds. The timing and amount of future contributions are entirely within the discretion of the investment funds. In July, 2000, we adopted a cash bonus plan to pay bonuses, after the return of invested capital, measured by the proceeds of a portion of the share of net profits from these investments, if any, to certain key employees who must remain employed with us at the time any bonuses become payable under the plan, subject to the terms and conditions of the plan. The principal purposes of this cash bonus plan was to retain key employees by allowing them to participate in a portion of the potential return from Forrester’s technology-related investments if they remained employed by the Company. The plan was established at a time when technology and internet companies were growing significantly, and providing incentives to retain key employees during that time was important. To date, we have not paid any bonuses under this plan.

In December 2003, we committed to invest an additional $2.0 million over an expected period of 2 years in an annex fund of one of the two private equity investment funds. As of March 31, 2005, we had contributed approximately $1.6 million to the annex fund. The timing of this additional investment is within the discretion of the fund.

During the three months ended March 31, 2005, we used $4.6 million of cash in financing activities, consisting of $4.8 million for repurchases of our common stock offset by $215,000 in proceeds from the exercise of employee stock options.

In February 2005, our Board of Directors authorized an additional $50.0 million to purchase common stock under the stock repurchase program. During the three months ended March 31, 2005, we repurchased 309,000 shares of common stock at an aggregate cost of approximately $4.8 million. As of March 31, 2005, we had repurchased 3.4 million shares of common stock at an aggregate cost of approximately $54.9 million.

During the three months ended March 31, 2004, we entered into a structured stock repurchase agreement giving us the right to acquire shares of our common stock in exchange for an up-front net payment of $1.5 million. The $1.5 million up-front net payment was recorded in stockholders’ equity as a reduction of additional paid-in capital and upon expiration of this agreement in May 2004, we received approximately $1.6 million in cash which was recorded as an increase to additional paid-in capital in the accompanying consolidated balance sheet.

As of March 31, 2005, we had cash and cash equivalents of $43.9 million and marketable securities of $87.8 million. We do not have a line of credit and do not anticipate the need for one in the foreseeable future. We plan to continue to introduce new products and services and expect to make minimal investments in our infrastructure during the next 12 months. We believe that our current cash balance, marketable securities, and cash flows from operations will satisfy working capital, financing activities, and capital expenditure requirements for at least the next two years.

As of March 31, 2005, we had future contractual obligations as follows for operating leases*:

We do not maintain any off-balance sheet financing arrangements.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following discussion about our market risk disclosures involves forward-looking statements. Actual results could differ materially from those projected in the forward-looking statements. We are exposed to market risk related to changes in interest rates and foreign currency exchange rates. We do not use derivative financial instruments for speculative or trading purposes.

INTEREST RATE SENSITIVITY. We maintain an investment portfolio consisting mainly of federal, state and municipal government obligations and corporate obligations, with a weighted-average maturity of less than one year. These available-for-sale securities are subject to interest rate risk and will decline in value if market interest rates increase. We have the ability to hold our fixed income investments until maturity (except for any future acquisitions or mergers). Therefore, we would not expect our operating results or cash flows to be affected to any significant degree by a sudden change in market interest rates on our securities portfolio. The following table provides information about our investment portfolio. For investment securities, the table presents principal cash flows and related weighted-average interest rates by expected maturity dates.

     Principal amounts by expected maturity in U.S. dollars are as follows:

FOREIGN CURRENCY EXCHANGE. On a global level, we face exposure to movements in foreign currency exchange rates. This exposure may change over time as business practices evolve and could have a material adverse impact on our financial results. Historically, our primary exposure has been related to non-U.S. dollar-denominated operating expenses in Canada and Asia, where we sell primarily in U.S. dollars. The introduction of the Euro as a common currency for members of the European Monetary Union has not, to date, had a significant impact on our financial position or results of operations. However, during the three-months ended March 31, 2005, currency translation resulted in a 1% increase in our revenues. To date, we have not entered into any hedging agreements. However, we are prepared to hedge against fluctuations that the Euro, or other foreign currencies, will have on foreign exchange exposure if this exposure becomes material. As of March 31, 2005, the total assets related to non-U.S. dollar denominated currencies that are subject to foreign currency exchange risk were approximately $24.0 million.

ITEM 4. CONTROLS AND PROCEDURES

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), as of March 31, 2005. Based on such evaluation, our principal executive officer and principal financial officer have concluded that as of such date, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable SEC rules and forms and were effective.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING
