ART TECHNOLOGY GROUP, INC.
NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(1) Organization, Business and Summary of Significant Accounting Policies
     Art Technology Group, Inc. (“ATG” or the “Company”) develops and markets a comprehensive suite of e-commerce software products, and provides related services including support and maintenance, education, application hosting, professional services and Optimization service solutions for enhancing online sales and support.
(a) Principles of Consolidation
     The accompanying unaudited condensed consolidated financial statements of the Company have been prepared pursuant to the rules of the Securities and Exchange Commission for quarterly reports on Form 10-Q and Article 10 of Regulation S-X. Accordingly, the financial statements do not include all of the information and footnotes required by United States generally accepted accounting principles, and while the Company believes that the disclosures presented are adequate to make the information presented not misleading, these financial statements should be read in conjunction with the audited financial statements and related notes included in the Company’s 2009 Annual Report on Form 10-K. In the opinion of management, the accompanying unaudited condensed consolidated financial statements and notes contain all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows at the dates and for the periods indicated. The operating results for the three and nine months ended September 30, 2010 are not necessarily indicative of the results to be expected for the full year ending December 31, 2010. The Company considers which events or transactions that occur after the balance sheet date but before the financial statements are issued should be included to provide additional evidence relative to certain estimates or to identify matters that require additional disclosures.
     The accompanying consolidated financial statements include the accounts of ATG and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
(b) Accounts Receivable
     Accounts receivable represents amounts currently due from customers. Accounts receivable also include $8.6 million and $2.5 million of unbilled accounts receivable at September 30, 2010 and December 31, 2009, respectively. Unbilled accounts receivable consist of future billings related to transactions with extended payment terms, as well as future billings for professional services performed but not yet invoiced to the customer. At September 30, 2010, $6.4 million of the $8.6 million was unbilled due to extended payment terms. At December 31, 2009, $1.0 million of the $2.5 million related to extended payment terms. Unbilled accounts receivable related to professional services are generally invoiced the following month.
(c) Comprehensive Income
     Accounting guidance requires financial statements to include the reporting of comprehensive income, which includes net income and certain transactions that have generally been reported in the statement of stockholders’ equity. ATG’s comprehensive income consists of net income, foreign currency translation adjustments and unrealized gains and losses on available-for-sale securities.
     The components of accumulated other comprehensive income are as follows (in thousands):
                                 
    Three months ended     Nine months ended  
    September 30,     September 30,  
    2010     2009     2010     2009  
Net income
  $ 4,173     $ 3,963     $ 10,406     $ 11,557  
Net changes in:
                               
Foreign currency translation adjustment
    827       426       (172 )     1,061  
Unrealized gain (loss) on available-for-sale securities
    283       (12 )     66       112  
 
                       
Total comprehensive income
  $ 5,283     $ 4,377     $ 10,300     $ 12,730

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(d) Concentrations of Credit Risk and Major Customers
     At September 30, 2010 and 2009 no customer accounted for more than 10% of accounts receivable. Furthermore, no customer accounted for more than 10% of revenues for either the three or nine month periods ended September 30, 2010 and 2009.
(e) New Accounting Pronouncements
     In September 2009, the FASB issued Accounting Standards Update (“ASU”) 2009-13, Multiple Element Arrangements. ASU 2009-13 addresses the determination of when the individual deliverables included in a multiple element arrangement may be treated as separate units of accounting. ASU 2009-13 also modifies the manner in which the transaction consideration is allocated across separately identified deliverables and establishes definitions for determining fair value of elements in an arrangement. This standard must be adopted by the Company no later than January 1, 2011 with earlier adoption permitted. The Company is currently evaluating the impact, if any, that this standard update will have on its consolidated financial statements.
(2) Net Income Per Share
     Basic net income per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing net income by the weighted average number of shares of common stock outstanding plus the dilutive effect of common stock equivalents using the treasury stock method. Common stock equivalents consist of stock options, restricted stock and restricted stock unit awards. Under the treasury stock method, the assumed proceeds, including the exercise price as well as the average unrecognized compensation expense of dilutive stock options and restricted stock awards, are used to effect an “assumed” buyback of additional shares, thereby reducing the dilutive impact of the stock options and restricted stock awards.
     The following table sets forth the computation of basic and diluted net income per share for the periods indicated (in thousands, except per share amounts):
                                 
    Three months ended     Nine months ended  
    September 30,     September 30,

(3) Stock-Based Compensation
Grant-Date Fair Value of Stock Options
     The Company uses the Black-Scholes option pricing model to estimate the grant-date fair value of stock options. Information pertaining to stock options granted during the nine months ended September 30, 2010 and 2009 and related weighted average assumptions is as follows:
                 
    Nine months ended September 30,
Stock Options   2010   2009
Options granted (in thousands)
    1,849       1,088  
Weighted-average exercise price
  $ 4.33     $ 2.84  
Weighted-average grant date fair value
  $ 2.72     $ 1.86  
Assumptions:
               
Expected volatility
    65.02 %     70.50 %
Expected term (in years)
    6.25       6.25  
Risk-free interest rate
    1.84 %     2.68 %
Expected dividend yield
           
     Expected volatility — The Company has determined that the historical volatility of its common stock is the best indicator of the future volatility of its common stock, and therefore uses historical volatility to estimate the grant-date fair value of stock options. Historical volatility is calculated for the period that is commensurate with the stock option’s expected term.
     Expected term — The expected term of an option is based on the historical experience for the population of option holders.
     Risk-free interest rate — The yield on zero-coupon U.S. Treasury securities for a period that is commensurate with the expected term is used as the risk-free interest rate.
     Expected dividend yield — The Company’s Board of Directors historically has not declared cash dividends and does not expect to issue cash dividends in the future.
     The Company uses the straight-line attribution method to recognize stock-based compensation expense for stock options. The amount of stock-based compensation recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Expected forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered option. The Company has applied a forfeiture rate of 9.6% to all unvested options as of September 30, 2010. This estimate is re-evaluated periodically and the forfeiture rate is adjusted as necessary. Ultimately, the actual expense recognized over the vesting period will only be for those shares that vest.
Stock Option Award Activity
     A summary of the activity under the Company’s stock option plans for the nine months ended September 30, 2010 is presented below:

     During the nine months ended September 30, 2010 and 2009, the total intrinsic value of options exercised (i.e. the difference between the market price at exercise and the price paid by the employee to exercise the options) was $2.3 million and $1.9 million, respectively, and the total amount of cash received by the Company from exercise of these options was $2.0 million and $1.4 million, respectively.
Restricted Stock Awards
     A summary of the Company’s restricted stock unit (“RSU”) award activity for the nine months ended September 30, 2010 is presented below:
                 
            Weighted
            Average Grant

Non-vested shares outstanding at September 30, 2010
    5,999       3.32  
       
     During the nine months ended September 30, 2010, the Company granted 2.7 million RSUs to employees, directors and executives. The fair value of the RSUs is based on the market value of ATG’s common stock price on the date of grant. Stock-based compensation expense related to RSUs is recognized on a straight-line basis over the requisite service period provided there are no performance-based measures. The Company has applied a forfeiture rate of 18% to its RSUs as of September 30, 2010.
     The RSUs provide the holder with the right to receive shares of ATG common stock upon vesting. RSUs granted to employees generally vest over four years. A majority of the RSUs vest based on the lapsing of time. A portion of the RSUs granted to executives are subject to performance criteria. Of the RSUs outstanding at September 30, 2010, 1.9 million were performance-based. The fair value of these performance-based awards is being recognized over the requisite service period under the accelerated method. All performance-based RSUs contain an additional condition which, if achieved, would result in the immediate vesting of the awards. At September 30, 2010, the achievement of this additional condition is not deemed probable by the Company.
     As of September 30, 2010, there was $20.4 million of total unrecognized compensation cost related to unvested awards of stock options and RSUs. That cost is expected to be recognized over a weighted-average period of 2.1 years.
     The Company recorded total stock-based compensation expense of $2.9 million and $2.5 million, respectively, for the three months ended September 30, 2010 and 2009 and $7.7 million and $6.8 million, respectively, for the nine months then ended.
(4) Disclosures About Segments of an Enterprise
     Operating segments are components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision-maker in making decisions on how to allocate resources and assess performance. The Company’s chief operating decision-maker is its Chief Executive Officer. ATG views its operations and manages its business as one segment with three product offerings: software licenses, recurring

services, and professional and education services. ATG evaluates these product offerings based on their respective revenues and gross margins. As a result, the financial information disclosed in the consolidated financial statements represents the material financial information related to our principal operating segment.
     Revenues from foreign sources were approximately $16.2 million and $12.7 million for the three months ended September 30, 2010 and 2009, respectively, and $41.3 million and $39.0 million for the nine months ended September 30, 2010 and 2009, respectively. Revenues from foreign sources were primarily generated from customers located in Europe. All of the Company’s product sales for the three and nine months ended September 30, 2010 and 2009 were delivered from ATG’s headquarters located in the United States.
     The following table represents the percentage of total revenue by geographic region for the three and nine month periods ended September 30, 2010 and 2009:

(5) Fair Value Measurement
     As defined in ASC 820-10, Fair Value Measurements and Disclosures (“ASC 820-10”), fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In order to increase consistency and comparability in fair value measurements, ASC 820-10 establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:
     Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.
     Level 2: Other inputs that are observable directly or indirectly, such as quoted prices for similar assets and liabilities or market corroborated inputs.
     Level 3: Unobservable inputs are used when little or no market data is available, which requires the Company to develop its own assumptions about how market participants would value the assets or liabilities. The fair value hierarchy gives the lowest priority to Level 3 inputs.
     In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible in its assessment of fair value.

     When available, the Company uses unadjusted quoted market prices to measure the fair value and classifies such items as Level 1. The valuation technique used to measure fair value for our Level 2 assets is a market approach, using prices and other relevant information generated by market transactions involving identical or comparable assets.
     As of September 30, 2010, the Company’s marketable securities had a fair value of $137.5 million, amortized cost of $137.4 million, and unrealized gain recorded in other comprehensive income of $0.1 million. In addition, 78% of the marketable securities held by the Company at September 30, 2010 had a maturity of less than one year, and all investments had fair value greater than 90% of their amortized cost.
(6) Restricted Cash
     At September 30, 2010, the Company has collateralized $0.8 million in outstanding letters of credit with certificates of deposit. The letters of credit were issued in favor of various landlords to secure obligations under ATG’s facility leases expiring through December 2018. The collateral for the letters of credit is reflected on the Company’s balance sheet as restricted cash within short-term and long-term marketable securities dependent on the underlying term of the leases.
(7) Acquisitions
     On January 8, 2010, the Company acquired all of the outstanding shares of common stock of privately held InstantService.com, Inc. (“InstantService”) in a non-material business combination. During the three months ended September 30, 2010, the Company did not record any material revisions to any of the assumptions, estimates or

amounts used to complete its preliminary purchase price accounting as of March 31, 2010; however, pending the outcome of further analysis related to certain other assets and contingencies recorded as part of the transaction, the preliminary purchase price allocation could change.
(8) Commitments and Contingencies
Indemnifications
     The Company in general agrees to indemnification provisions in its software license agreements and service agreements in the ordinary course of its business.
     With respect to software license and service agreements, these indemnifications generally include provisions indemnifying the customer against losses, expenses, and liabilities from damages that may be awarded against the customer in the event the Company’s software is found to infringe upon the intellectual property rights of others. The software license and service agreements generally limit the scope of and remedies for such indemnification obligations in a variety of industry-standard respects. The Company relies on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect its intellectual property rights. The Company believes such laws and practices, along with its internal development processes and other policies and practices, limit its exposure related to the indemnification provisions of the software license agreements and service agreements. However, in recent years there has been significant litigation in the United States involving patents and other intellectual property rights. Companies providing Internet-related products and services are increasingly bringing and becoming subject to suits alleging infringement of proprietary rights, particularly patent rights. From time to time, the Company’s customers have been subject to third party patent claims, and the Company has agreed to indemnify these customers from claims to the extent the claims relate to the Company’s products.
(9) Goodwill and Intangible Assets
Goodwill
     The Company evaluates goodwill for impairment annually and whenever events or changes in circumstances suggest that the carrying value of goodwill may not be recoverable. No impairment of goodwill resulted from the Company’s most recent evaluation of goodwill for impairment, which occurred in the fourth quarter of fiscal 2009, nor in any of the periods presented. The Company’s next annual impairment assessment will be made in the fourth quarter of 2010. The following table presents the changes in goodwill during fiscal 2010 and 2009 (in thousands):

Intangible Assets
     The Company reviews identified intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. Recoverability of these assets is measured by comparison of their carrying value to future undiscounted cash flows the assets are expected to generate over their remaining economic lives. If such assets are considered to be impaired, the impairment to be recognized in the statement of operations equals the amount by which the carrying value of the assets exceeds their fair value determined by either a quoted market price, if any, or a value determined by utilizing a discounted cash flow technique.

     Intangible assets are amortized based upon the pattern of estimated economic use or on a straight-line basis over their estimated useful lives, which range from 1 to 5 years. Amortization expense related to intangibles was $1.2 million and $0.9 million for the three-month periods ended September 30, 2010 and 2009, respectively, and $3.6 million and $2.8 million for the nine-month periods ended September 30, 2010 and 2009, respectively.

(10) Income Taxes
     The Company records a deferred tax asset or liability based on the difference between the financial statement and tax bases of assets and liabilities, as measured by enacted tax rates assumed to be in effect when these differences reverse. The Company believes there is significant uncertainty in its future profits due to the growing breadth of its product mix and the effect that can have on the timing of revenue recognition, and the related effect on reported U.S. income. At September 30, 2010, the Company determined that it is more likely than not that the net U.S. deferred tax assets may not be realized and a full valuation allowance continues to be recorded.
     The $0.3 million income tax provision recorded for the three month period ended September 30, 2010 relates to the U.S. alternative minimum tax (“AMT”), inclusive of allowable tax loss carryforwards, state and foreign income taxes as well as interest related to uncertain tax positions. The AMT liability is available as a credit against future tax obligations upon the full utilization or expiration of our net operating loss carryforwards. The $0.2 million benefit for the nine months ended September 30, 2010 includes approximately $1.4 million related to the reversal of the valuation allowance on certain deferred tax assets as described below.
     During the nine months ended September 30, 2010, the Company recorded net deferred tax liabilities of approximately $1.4 million related to basis differences resulting from the acquisition of InstantService. As a result of the InstantService acquisition, the Company released a portion of its valuation allowance amounting to approximately $1.4 million to offset the impact of the deferred tax liabilities acquired on its pre-acquisition net deferred tax asset balance. In accordance with ASC 805, Business Combinations, the release of the valuation allowance was recorded as a tax benefit in the statement of operations.
     For the three and nine months ended September 30, 2009, the Company recorded income tax benefits of $1.7 million and $0.8 million, respectively, which related to the tax benefits recorded as a result of the decreases in the Company’s uncertain tax positions offset by U.S. federal alternative minimum tax, state and foreign income taxes.
(11) Litigation
     In December 2001, a purported class action complaint was filed against the Company’s wholly owned subsidiary Primus Knowledge Solutions, Inc., two former officers of Primus and the underwriters of Primus’ 1999 initial public offering. The complaints are similar and allege violations of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, primarily based on the allegation that the underwriters received

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
undisclosed compensation in connection with Primus’ initial public offering. The litigation has been coordinated in the United States District Court for the Southern District of New York with claims against approximately 300 other companies that had initial public offerings during the same general time period. The parties have reached a global settlement of the litigation under which insurance will pay the full amount of the settlement share allocated to Primus, and Primus bears no financial liability. In October 2009, the Court issued an order granting final approval of the settlement. Certain objectors are appealing the final order. While the Company cannot predict the outcome of the litigation, it does not expect any material adverse impact to its business, or the results of its operations, from this matter.
     In May 2009, LivePerson, Inc. (“LivePerson”) commenced an action in the United States District Court for the Southern District of New York against InstantService. In the action, LivePerson alleges that InstantService infringes two United States patents held by LivePerson and seeks injunctive relief, damages and attorneys’ fees. In April 2010, InstantService asserted counter-claims against LivePerson, alleging that LivePerson infringes one of InstantService’s patents and is seeking injunctive relief, damages and attorneys fees. In May 2010, the Company joined the action and asserted counter claims against LivePerson, alleging that LivePerson infringes two of its patents and is seeking injunctive relief, damages and attorneys fees against LivePerson. In August 2010, LivePerson added the Company as a defendant to the suit. The Company is investigating the claims made by LivePerson and has reached no conclusion as to the likelihood of an adverse outcome in the litigation, which the Company intends to contest vigorously.
(12) Subsequent Events
Merger Agreement with Oracle (Non-recognized subsequent event)
     On November 2, 2010, ATG, Oracle Corporation, a Delaware corporation (“Oracle”), and Amsterdam Acquisition Sub Corporation, a Delaware corporation and wholly-owned subsidiary of Oracle (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, subject to satisfaction or waiver of the conditions therein, Merger Sub will merge with and into ATG (the “Merger”) with ATG surviving as a wholly-owned subsidiary of Oracle. A description of the Merger Agreement is contained in the Company’s Current Report on Form 8-K filed with the SEC on November 2, 2010, and a copy of the Merger Agreement is attached thereto as Exhibit 2.1.
Shareholder Lawsuit (Non-recognized subsequent event)
     On November 4, 2010, a putative shareholder class action lawsuit was filed in the Court of Chancery in the State of Delaware in and for New Castle County (Cronenwett v. Art Technology Group, Inc. et al) naming the Company and its directors, as well as Oracle Corporation and its wholly-owned subsidiary Amsterdam Acquisition Sub Corporation, as defendants. The complaint seeks to enjoin the proposed acquisition of the Company by Oracle Corporation and alleges claims for breach of fiduciary duty against the Company’s directors and for aiding and abetting a breach of fiduciary duty against Oracle Corporation and Amsterdam Acquisition Sub Corporation. The complaint generally alleges that the consideration offered in the proposed transaction is unfair and inadequate. The Company intends to defend this case vigorously. There can be no assurance, however, that the Company will be successful in its defense of this action. It is not known when or on what basis the action will be resolved.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Overview
     This Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our condensed consolidated financial statements and the notes contained in Item 1 of this Quarterly Report on Form 10-Q. The following discussion contains forward-looking statements. The forward-looking statements do not include the potential impact of any mergers, acquisitions, or divestitures of business combinations that may be announced after the date hereof.
     We develop and market a comprehensive suite of e-commerce software solutions, as well as provide related services in conjunction with our products, including support and maintenance, professional services, managed application hosting services, and Optimization services for enhancing online sales and support. We primarily derive revenue from the sale of software products and related services. Our software licenses are priced based on the size of the customer implementation. Our recurring services revenue is attributable to managed application hosting services, Optimization services, and support and maintenance services. Managed application hosting revenue is recognized monthly as the services are provided and pricing is based on a per transaction, per CPU or percent of customer’s revenue basis. Optimization services are priced on a per transaction basis and recognized monthly as the services are provided. Support and maintenance arrangements are priced based on the level of support services provided as a percent of net license fees per annum. Under support and maintenance services, customers are generally entitled to receive software upgrades and updates, maintenance releases and technical support. Professional and education services revenue includes implementation, technical consulting and education training. We bill professional service fees primarily on a time and materials basis. Education services are billed as services are provided.
Recent Developments
     On November 2, 2010, our Company, Oracle Corporation, a Delaware corporation (“Oracle”), and Amsterdam Acquisition Sub Corporation, a Delaware corporation and wholly-owned subsidiary of Oracle (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, subject to satisfaction or waiver of the conditions therein. Merger Sub will merge with and into our Company (the “Merger”) with our Company surviving as a wholly-owned subsidiary of Oracle. A description of the Merger Agreement is contained in our Current Report on Form 8-K filed with the SEC on November 2, 2010, and a copy of the Merger Agreement is attached thereto as Exhibit 2.1.
Shift to Increasing Ratably Recognized Revenue
     Before 2007, most of our revenue from arrangements involving the sale of our software was derived from perpetual software licenses and in most circumstances was recognized at the time the license agreement was executed and the software was delivered. Beginning in the first quarter of 2007, an increasing number of our perpetual software license arrangements have also included the sale of our managed application hosting services or Optimization services. As a result of applying the requirements of accounting principles generally accepted in the United States of America, (“GAAP”) to our evolving business model, the revenue from these arrangements with combined product offerings is recognized on a ratable basis over the estimated term of the contract or in certain cases over the estimated term of the customer arrangement, commencing with the “site-delivered” date for providing the managed application hosting services or Optimization services.
     The addition of Optimization services and managed application hosting services solution offerings introduced new products to our portfolio for which we do not have vendor-specific objective evidence (or “VSOE”) of fair value. As a result, when we sell Optimization services and managed application hosting services in conjunction with e-commerce software, we defer all up-front fees, such as those for licenses, support and maintenance, and professional services, received prior to the delivery of the managed application hosting services or Optimization services. We recognize revenue from these fees ratably over either the term of the contract or estimated life of the arrangement depending on the specific facts of the arrangement, commencing with the “site-delivered” date for providing the managed application hosting services or Optimization services. In addition, when professional services revenue is deferred in connection with these arrangements and other instances in which there are undelivered elements to a transaction for which we do not have VSOE of fair value, we defer the direct costs related to performing the professional services prior to delivery of the element related to these services. These amounts are recognized to cost of revenue ratably in the same manner as the related revenue.
Key measures that we use to evaluate our performance:
     In addition to the traditional measures of financial performance that are reflected in our results of operations determined in accordance with GAAP, we also monitor certain non-GAAP financial measures related to the performance of our business. A “non-GAAP financial measure” is a numerical measure of a company’s historical or future financial performance that excludes amounts that are included in the most directly comparable measure

15


Table of Contents

ART TECHNOLOGY GROUP, INC.
calculated and presented in the GAAP statement of operations. Among the GAAP and non-GAAP measures that we believe are most important in evaluating the performance of our business are the following:
    We use product license bookings, a non-GAAP financial measure, as an important measure of growth in demand for our ATG e-commerce platform and the success of our sales and marketing efforts. We define product license bookings as the sale of perpetual software licenses regardless of the timing of revenue recognition under GAAP. When considering the value of perpetual software licenses executed during the period we use our judgment in assessing collectability and likelihood of granting future concessions. Factors that we consider include the financial condition of the customer and contractual provisions included in the license contract. See “Results of Operations-Product License Bookings” below.
 
      Product license revenue associated with a particular transaction may be deferred for reasons other than the presence of a managed application hosting or Optimization services arrangement, such as the presence of credit risk or other contractual terms that, under GAAP, require us to defer the recognition of revenue. The deferred revenue for such a transaction may be recognized in a single future period rather than ratably when the conditions that originally required deferral have been resolved. We include all additions to deferred product license revenue in our calculation of product license bookings.
 
    We use cash flow from operations as an indicator of the success of the business. Because a portion of our revenue is deferred in the near term, our net income may be significantly different from the cash that we generate from operations.
 
    We use recurring services revenue, as reported under GAAP, to evaluate the success of our strategy to deliver site-independent online services and the growth of our recurring revenue sources. Recurring services revenue includes Optimization services, application hosting services, and support and maintenance related to ATG e-commerce platform sales.
 
    We use revenue and gross margins on our various lines of business to measure our success at meeting cash and non-cash cost and expense targets in relation to revenue earned.
 
    We use days sales outstanding (“DSO”), calculated by dividing accounts receivable at period end (including unbilled accounts receivable which may exist as a result of extended payment terms) by revenue and multiplying the result by the number of days in the period. The percentage of accounts receivable that are less than 60 days old is an important factor that our management uses to understand the strength of our accounts receivable portfolio. This measure is important because a disproportionate percentage of our product license bookings often occur late in the quarter, which has the effect of increasing our DSO.
Trends in On-Line Sales and our Business
     Set forth below is a discussion of recent developments in our industry that we believe offer us significant opportunities, or present us with significant challenges, and have the potential to significantly influence our results of operations.
     Impact of recovering economy. The rate of recovery from the global recession impacts all sectors of the U.S. and most foreign economies and continues to create uncertainty for our business. These fragile economic conditions have led to delays or reductions in capital spending, including purchases of information technology across industries and markets including customers across the markets that we serve. We cannot accurately predict the duration or potential severity of the current economic uncertainty or the impact it will have on our customers’ or their demand for our products and services.
     Trend in on-line sales. The growth of e-commerce as an important sales channel is the principal driver for demand for our products and services. We believe that in the current environment, the on-line channel continues to grow in importance for many of our customers, as e-commerce may offer more opportunities for revenue growth as well as significant cost savings and operational benefits such as improved inventory control and purchasing processes.

     E-commerce “replatforming.” Enterprises periodically upgrade or replace the network and enterprise applications software and the related hardware systems that they use to run their e-commerce operations in order to take advantage of advances in computing power, system architectures, and enterprise software functionality that enable them to increase the capabilities of their e-commerce systems while simplifying operation and maintenance of these systems and reducing their cost of ownership. In the e-commerce software industry, we refer to these major system upgrades or replacements as “replatforming.” We believe that on average, customers in our market replatform or refresh their e-commerce software approximately every four to five years. The extent to which this trend will continue is unknown. However, we are cautiously optimistic that in the near term spending on e-commerce technology will continue at levels comparable to those we have recently experienced, and that it may even increase as a priority for some of our customers and prospects, due to the growing importance and cost benefits of the on-line channel.
     Emergence of the “on demand” model of Software as a Service (“SaaS”). An important trend throughout the enterprise software industry in recent years has been the emergence of the SaaS software delivery model whereby a software vendor that has developed a software application hosts and operates it for use by its customers over the Internet. The emergence of SaaS has been driven by customers’ desire to reduce the costs of owning and operating critical applications software, while shifting the risks and burdens associated with operating and maintaining the software to the software vendor, enabling the customer to focus its resources on its core business.
     Rapidly evolving and increasingly complex customer requirements. The market for e-commerce is constantly and rapidly evolving, as we and our competitors introduce new and enhanced products, retire older ones, and react to changes in Internet-related technology and customer demands. The market for e-commerce has seen diminishing product differentiators, increasing product commoditization, and evolving industry standards. To succeed, we need to enhance our current products and develop or acquire new products on a timely basis to keep pace with market needs, satisfy the increasingly sophisticated requirements of customers, and leverage strategic alliances with third parties in the e-commerce field who have complementary products. Our customers may request that we structure our arrangements with them in new ways that may impact the timing of revenue recognition and cash flows.
     International expansion. Revenues derived from foreign sales as a percentage of our total revenues were 32% and 29%, respectively, for the three and nine months ended September 30, 2010, remaining relatively stable compared to 29% and 30%, respectively, for the three and nine months ended September 30, 2009. We continue to seek opportunities to invest resources into further developing our reach internationally. In support of this initiative we have entered into partnership agreements abroad that will support our continued growth. As the international market opportunity continues to develop we will adjust our strategy accordingly.
     Competitive trend. The market for online sales, marketing, and customer service software is intensely competitive, subject to rapid technological change, and significantly affected by new product introductions by large competitors with significantly greater resources and installed customer bases. We expect competition to persist and intensify in the future.
     Virtualization. The trend towards virtualization could challenge our current software license pricing structure. Virtualization is an approach to computing wherein the actual, physical hardware resources of a computer system are configured to simulate the operations of one or more abstract computers, known as “virtual machines,” on which software can be executed. The introduction of virtualization technologies may require us to consider alternative pricing strategies.
     Development of ATG’s partner ecosystem. As we train and develop our ATG partner ecosystem we will see a larger number of implementations outsourced to these partners resulting in stable, or potentially lower, professional services revenue.

Critical Accounting Policies and Estimates
     This management’s discussion and analysis of financial condition and results of operations discusses our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the 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. On an ongoing basis, management evaluates its estimates and judgments, including those related to revenue recognition, deferral of costs, the allowance for accounts receivable, research and development costs, the impairment of long-lived assets and goodwill, income taxes, and assumptions for stock-based compensation. Management bases its estimates and judgments on historical experience, known trends, or events and various other factors 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 define our “critical accounting policies” as those that require us to make subjective estimates about matters that are uncertain and are likely to have a material impact on our financial condition and results of operations or that concern the specific manner in which we apply GAAP. Our estimates are based upon assumptions and judgments about matters that are highly uncertain at the time the accounting estimate is made and applied and require us to assess a range of potential outcomes. We have not made any changes to any of our critical accounting policies or our procedures for developing material estimates from those disclosed in our Annual Report on Form 10-K for the year ended December 31, 2009, as filed with the Securities and Exchange Commission on February 1, 2010.

Product License Bookings
     We use product license bookings, a non-GAAP financial measure, as an important measure of growth in demand for our ATG Commerce and the success of our sales and marketing efforts. We define product license bookings as the sale of perpetual software licenses regardless of the timing of revenue recognition under GAAP. When considering the value of perpetual software licenses executed during the period we use our judgment in assessing collectability and likelihood of granting future concessions. Factors that we consider include the financial condition of the customer and contractual provisions included in the license contract.
     The following table summarizes and reconciles to our product license revenue, as reported under GAAP, our product license bookings for the periods presented:
                                 
    Three months ended   Nine months ended
    September 30,   September 30,

Product license revenue
  $ 13,729     $ 10,890     $ 42,937     $ 37,396  
         
     Product license bookings increased $3.8 million, or 36%, to $14.2 million and increased $6.8 million, or 17% to $46.3 million in the three and nine months ended September 30, 2010, respectively, when compared to the same periods in 2009. The increase in both cases reflects growth in the demand for our e-commerce solutions and the success of our sales and marketing initiatives.
     Product license bookings deferred was 26% and 41% of our total product license bookings for the three months ended September 30, 2010 and 2009, respectively, and 31% and 41%, respectively, for the nine month periods then ended. The deferral of bookings is due to various factors which may include e-commerce Optimization services or application hosting included in the arrangement for which we do not have VSOE of fair value, extended payment terms in the arrangement, the inclusion of hosting services in the arrangement which may require that revenue be deferred and recorded over the estimated customer life, or other elements in our contracts that preclude recognition of revenue at the time of booking. Deferred revenue will be recognized in future periods when delivery of the service commences or as contractual requirements are met.
     Product license deferred revenue recognized was $3.2 million and $4.8 million for the three month periods ended September 30, 2010 and 2009, respectively, and $11.2 million and $14.3 million, respectively, for the nine month periods then ended. These amounts were recognized upon the resolution of contractual conditions or other conditions that required their initial deferral.

Total revenue
  $ 50,335     $ 43,381     $ 144,222     $ 129,719  
     Total revenue increased $7.0 million, or 16%, to $50.3 million and increased $14.5 million, or 11% to $144.2 million, respectively, in the three and nine months ended September 30, 2010 when compared to the same periods in 2009. Revenue is derived from perpetual software licenses, recurring services, which is comprised of support and maintenance services, application hosting services, and e-commerce optimization services, and professional and education services. The revenue growth in 2010 is primarily due to a combined increase of $17.6 million, or 16%, in product license and recurring services revenues, which was partially offset by a decrease of $3.0 million, or 15% in professional and education services. Information on revenue changes, by type, for the three and nine month periods ended September 30, 2010 compared to the same periods in 2009 is provided below.
     Revenue generated from international customers increased to $16.2 million or 32% of total revenue from $12.7 million, or 29% of total revenue, respectively, for the three months ended September 30, 2010 when compared to the same period in 2009. International revenue also increased to $41.3 million or 29% of total revenue from $39.0 million, or 30% of total revenue, respectively, for the nine month periods ended September 30, 2010 and 2009. The primary driver of the overall increase in foreign source revenues as a percentage of total revenues compared to similar periods in the prior year was the consummation of two significant product license transactions totaling $5.0 million in revenue recognized during the quarter ended September 30, 2010. Offsetting this amount is an increase in U.S. revenues in 2010 as a result of the addition of the InstantService business acquired January 8, 2010, as InstantService’s customer portfolio is primarily U.S. based.
     No customer accounted for more than 10% of revenues for either the three or nine month periods ended September 30, 2010 and 2009.

The increase experienced in the three months ended September 30, 2010 compared to the same period in 2009 is due to an increase in current period product license bookings of $3.8 million and a decrease in product license deferred revenue of $0.6 million offset by a decrease in the recognition of previously deferred product license revenue of $1.6 million. The increase experienced in the nine months ended September 30, 2010 compared to the same period in 2009 is based on an increase in product license bookings of $6.8 million and a decrease in product license deferred revenue of $1.8 million offset by a decrease in the recognition of previously deferred product license revenue of $3.1 million. Bookings have increased due to increased demand for our e-commerce solutions and the success of our sales and marketing initiatives.
     Product license revenue generated from international customers was $6.1 million and $13.4 million, respectively, for the three and nine months ended September 30, 2010 compared to $4.4 million and $14.9 million, respectively, for the same periods in 2009.

    Support and maintenance revenue increased $2.2 million, or 17%, to $14.6 million and increased $4.8 million, or 13.0% to $40.6 million, respectively, in the three and nine months ended September 30, 2010 when compared to the same periods in 2009, primarily as a result of continued renewal rates of 98% for the three months ended September 30, 2010 and 99% for the nine months then ended, coupled with growth in our installed base of ATG e-commerce software.
 
    e-Commerce optimization services and managed application hosting services revenue increased $3.1 million, or 25%, to $15.6 million and increased $7.3 million, or 20% to $43.4 million, respectively, in the three and nine months ended September 30, 2010 when compared to the same periods in 2009 primarily as a result of the addition of InstantService revenues not included in the prior year and growth in the average contract size for customers purchasing e-commerce Optimization services.
     Recurring service revenue generated from international customers was $7.2 million and $20.4 million, respectively, for the three and nine months ended September 30, 2010 compared to $6.7 million and $19.3 million, respectively, for the same periods in 2009.

     Professional and education services revenue consists primarily of revenue from consulting and implementation services, which typically are performed in the quarters closely following the execution of a product license transaction. Our professional services and education revenue decreased $1.1 million, or 15%, to $6.4 million and decreased $3.0 million, or 15.0% to $17.2 million, respectively, in the three and nine months ended September 30, 2010 when compared to the same periods in 2009, primarily due to the continued winding down of the government funded research business that we acquired with CleverSet in 2008 and the deferral of revenue on multiple element arrangements.
     Professional services and education revenue generated from international customers was $3.0 million and $7.5 million, respectively, for the three and nine months ended September 30, 2010 compared to $1.6 million and $4.1 million , respectively, for the same periods in 2009.

     Cost of recurring services revenues includes salary, benefits, and stock-based compensation and other costs for recurring services support staff, costs associated with the hosting centers, third-party contractors, amortization of technology acquired in connection with acquisitions, and royalties.
     When we perform professional consulting and implementation services in connection with managed application hosting arrangements we generally defer the direct costs incurred prior to delivery of the element related to the performance of these services. Deferred costs are amortized to cost of revenue ratably over the longer of the contract term or the estimated life of the arrangement once services commence.
     Cost of recurring services revenue increased $1.5 million, or 16%, to $10.9 million and increased $3.8 million, or 14% to $30.8 million, respectively, in the three and nine months ended September 30, 2010 when compared to the same periods in 2009. The increase in cost of recurring services in the three months ended September 30, 2010 is primarily related to increased salary and benefit-related costs of $0.6 million due to increased headcount stemming from the InstantService acquisition, an increase in depreciation and amortization expense of $0.7 million related to equipment purchases made in 2010 to support new hosting customers and to intangible assets obtained as part of the InstantService acquisition, and an increase in telecommunications and hosting expenses of $0.6 related to our new hosting customers. The causes of the increases in salaries and benefit related costs of $1.8 million, depreciation and amortization expense of $1.4 million and telecommunications and hosting expenses of $0.7 million in the nine months ended September 30, 2010 when compared to the prior year, are consistent with those experienced in the three months then ended.

     Cost of professional and education services revenue includes salary, benefits, and stock-based compensation and other costs for professional services and technical support staff and third-party contractors.
     Cost of professional and education services revenue decreased $0.3 million, or 4%, to $5.8 million and decreased $1.4 million, or 8% to $15.4 million, respectively, in the three and nine months ended September 30, 2010 when compared to the same periods in 2009. The decrease in cost of professional and education services in the three months ended September 30, 2010 is primarily driven by a decrease in outside service expenses of $0.7 related to a reduction in cost for contract/temporary labor due to the winding down of the of the government funded research business that we acquired with CleverSet in 2008 coupled with a $0.5 million increase in the amount of costs that were deferred on multiple element arrangements that will not be recorded until recognition of revenue commences. These decreases were offset by an increase in salary and benefit and travel-related costs of $0.8 million. The decrease in cost of professional and education services in the nine months ended September 30, 2010 is primarily related to a decrease in outside service expenses of $0.4 coupled with a $3.1 million increase in the amount of costs that were deferred on multiple element arrangements, offset by an increase in salary and benefit and travel-related costs of $1.8 million. The decrease in professional and education services gross margins for both the three and nine months ended September 30, 2010, was caused by increases in the use of outside contractors in 2010 compared to 2009 which resulted in higher cost.

     Research and development expenses consist primarily of salary, benefits, and stock-based compensation costs to support product development. To date all of our software development costs have been expensed as research and development costs in the period incurred.
     Research and development expenses increased $1.4 million, or 18%, to $9.0 million and increased $3.1 million, or 13% to $25.8 million in the three and nine months ended September 30, 2010, respectively, when compared to the same periods in 2009. Over the same periods, research and development expenses as a percentage of total revenue remained relatively consistent. The increase for the three month period ended September 30, 2010 compared to the same period in 2009 is primarily related to increases in salary and benefit expenses of $1.2 million coupled with an increase in cost related to contract/temporary labor of $0.2 million. Increases in salary and benefits were a result of increased headcount over the prior year and the increase in contract/temporary labor is related to our increased research and development activities. The increase for the nine month period ended September 30, 2010 compared to the same period in 2009 primarily relates to increases in salary and benefit expenses of $2.6 million, in contract/temporary labor of $0.3 million and in travel related expenses of $0.2 million. The primary drivers of the increases during the nine months ended September 30, 2010 compared to the same period

in 2009 are the same as those experienced over the three month period then ended. The increase in travel related expenses is due to the fact that many of the outside contractors used are based internationally.
     During the three and nine month periods ended September 30, 2010, we capitalized $0.5 million and $1.1 million, respectively, in certain internal use software development costs related to our optimization and hosting services in accordance with ASC 350-40, Internal-Use Software. We capitalized an insignificant amount of these cost during the three and nine month periods ended September 30, 2009.

     Sales and marketing expenses consist primarily of salaries, commissions, benefits, and stock-based compensation and other related costs for sales and marketing personnel, travel, public relations and marketing materials and events. We generally recognize commission expense upon contract execution with the result that commission expense may be recognized earlier than the related revenue.
     Sales and marketing expenses increased $2.7 million, or 22%, to $15.2 million and increased $7.8 million, or 21% to $45.1 million in the three and nine months ended September 30, 2010, respectively, when compared to the same periods in 2009. Sales and marketing expenses as a percentage of total revenue remained relatively consistent when compared to the three and nine month periods of the prior year. The increase for the three month period ended September 30, 2010 compared to the same period in 2009 is primarily related to increases in salary and benefit expenses of $2.3 million and an increase of $0.4 million in travel related expenses. The increase in salary and benefit expenses was driven by increased headcount and an increase in commissions of $1.2 million due to higher bookings. The increase for the nine month period ended September 30, 2010 compared to the same period in 2009 is primarily related to increases in salary and benefit expenses of $5.0 million, driven by increased headcount and an increase in commissions of $1.9 million due to higher bookings coupled with increases in travel and entertainment related expenses of $1.3 million and other direct expenses, such as amortization and facilities charges, of $1.2 million.

     General and administrative expenses increased $0.3 million, or 7%, to $5.2 million and increased $1.4 million, or 10% to $15.4 million in the three and nine months ended September 30, 2010, respectively, when compared to the same periods in 2009. General and administrative expenses as a percentage of total revenues remained relatively consistent when compared to the three and nine month periods of the prior year. The increase for the three month period ended September 30, 2010 compared to the same period in 2009 is primarily related to an increase in salary and benefit expenses of $0.5 million. The increase for the nine month period ended September 30, 2010 compared to the same period in 2009 primarily relates to an increase in salary and benefit expenses of $1.5 million.

Stock-Based Compensation Expense
     Stock-based compensation expense was $2.9 million and $2.5 million for the three month periods ended September 30, 2010 and 2009, respectively, and was $7.7 million and $6.8 million for the nine month periods ended September 30, 2010 and 2009, respectively, and is reflected in our costs and expenses above based on the function of the relevant personnel. As of September 30, 2010, the total compensation cost related to unvested awards not yet recognized in the statement of operations was approximately $20.4 million, which will be recognized over a weighted average period of approximately 2.1 years.
Interest and Other Income (Expense), Net
     Interest and other income (expense), net was $0.8 million and ($0.3) million for the three months ended September 30, 2010 and 2009, respectively, and $0.7 million and $0.2 million for the nine months ended September 30, 2010 and 2009, respectively. The changes for both the three and nine month periods compared to the same periods in 2009 primarily related to favorable changes in foreign exchange rates and net increases in interest income in both the three and nine month periods in 2010 due to the increase in our marketable securities balances.
Provision for Income Taxes
     Our $0.3 million income tax provision recorded for the three month period ended September 30, 2010 relates to the U.S. alternative minimum tax (“AMT”), inclusive of allowable tax loss carryforwards, state and foreign income taxes as well as interest related to uncertain tax positions. Our AMT liability is available as a credit against future tax obligations upon the full utilization or expiration of our net operating loss carryforwards. Our $0.2 million benefit for the nine months ended September 30, 2010 includes approximately $1.4 million related to the reversal of the valuation allowance on certain deferred tax assets as described below.
     During the nine months ended September 30, 2010, we recorded net deferred tax liabilities of approximately $1.4 million related to basis differences resulting from the acquisition of InstantService. As a result of the InstantService acquisition, we released a portion of our valuation allowance amounting to approximately $1.4 million to offset the impact of the deferred tax liabilities acquired on our pre-acquisition net deferred tax asset balance. In accordance with ASC 805, Business Combinations, the release of the valuation allowance was recorded as a tax benefit in our statement of operations.
     For the three and nine months ended September 30, 2009, we recorded income tax benefits of $1.7 million and $0.8 million, respectively, which related to the tax benefits recorded as a result of decreases in our uncertain tax positions offset by U.S. federal alternative minimum tax, state and foreign income taxes.
     We account for our uncertain tax positions in accordance with ASC 740-10, Income Taxes. During the quarter ended September 30, 2010, there was no change in our gross liability for unrecognized tax benefits. Through the nine months ended September 30, 2010 we have recorded less than $0.1 million of interest and penalties in our statement of operations and at September 30, 2010, we have approximately $0.1 million of potential interest and penalties accrued in our statement of financial position. If the uncertain tax positions are ultimately resolved in our favor, the effective tax rates in any future periods would be favorably affected by approximately $0.4 million.
Liquidity and Capital Resources
     Our capital requirements relate primarily to labor costs, facilities, employee and customer infrastructure, and working capital requirements. Our primary sources of liquidity at September 30, 2010 were our cash, cash equivalents, short and long-term marketable securities of $182.5 million, including $0.8 million of restricted cash used to collateralize letters of credit, and our cash flows from operations.
     Cash provided by operating activities was $32.5 million for the nine months ended September 30, 2010, an increase of $9.5 million compared to the same period in the prior year. This increase is primarily driven by an increase in cash inflows related to deferred revenue of $19.7 million, to $15.6 million, compared to a cash outflow of ($4.1) million in the nine months ended September 30, 2009. This increase was offset by an increase in cash outflows related to deferred costs, accounts payable and prepaid and other assets over the same periods of $3.8

million, $4.9 million and $3.4 million, respectively. The increase in deferred revenue was driven by improved renewal rates for support and maintenance contracts and the entrance into certain hosting contracts and professional service engagements during the nine months ended September 30, 2010 which require the deferral of revenue. The change in deferred costs relates to work performed on projects where both costs and revenues are being deferred until certain contractual terms are met and the increased cash outflows related to accounts payable are due to timing of vendor payments during the period. Finally, the change in our prepaid expenses and other current assets account is primarily related to prepayment of rent and information technology related support fees.
     Net cash used in investing activities was $123.8 million for the nine months ended September 30, 2010, an increase of $105.6 million compared to the nine months ended September 30, 2009. The difference is primarily driven by a net cash outflow in purchases/settlements of marketable securities of $97.8 million as a result of cash raised from our equity offering coupled with cash outflows of $15.2 million related to our acquisition of InstantService, net of cash acquired and $5.3 million related to the purchase of property and equipment. We do not expect any material adjustments to the cash flows related to the IntantService acquisition in the fourth quarter of 2010 and would expect continued changes in our net cash flows related to our marketable securities as certain investments mature and are either reinvested or converted to cash.
     Net cash provided by financing activities was $92.6 million for the nine months ended September 30, 2010, an increase of $95.5 million compared to the same period in the prior year. The difference between the periods primarily relates to a cash inflow of $95.0 million in net proceeds from our February 2010 equity offering.
     We believe that our cash equivalents, and marketable securities, along with other working capital and cash expected to be generated by our operations, will allow us to meet our liquidity requirements over at least the next twelve months and for the foreseeable future; however, our actual cash requirements will depend on many factors, including particularly, overall economic conditions both domestically and abroad. We may find it necessary or advisable to seek additional external funds through public or private securities offerings, strategic alliances or other financing sources. There can be no assurance that if we seek external funding, it will be available on favorable terms, if at all.
     On October 27, 2009 our Board of Directors authorized a stock repurchase program providing for the repurchase of up to $25.0 million of our outstanding common stock in the open market or in privately negotiated transactions, at times and prices considered appropriate depending on the prevailing market conditions. This authorization was in addition to the remaining $3.9 million under our existing $20.0 million repurchase program authorized in April 2007. During the nine months ended September 30, 2010, we repurchased 444,600  shares of our common stock. Over the life of the stock repurchase program through September 30, 2010, we have repurchased 7,134,695  shares of our common stock at a cost of $17.6 million.

     We evaluate our performance on collections on a quarterly basis. As of September 30, 2010, our days sales outstanding increased from December 31, 2009 due to timing of sales and associated billings during the quarter, as well as the effect of receiving payments on sales made during the current and previous quarters.
Recent Accounting Pronouncements
     In September 2009, the FASB issued ASU 2009-13, Multiple Element Arrangements. ASU 2009-13 addresses the determination of when the individual deliverables included in a multiple arrangement may be treated as separate units of accounting. ASU 2009-13 also modifies the manner in which the transaction consideration is allocated across separately identified deliverables and establishes definitions for determining fair value of elements in an arrangement. This standard must be adopted by us no later than January 1, 2011, with earlier adoption permitted. We are currently evaluating the impact, if any, that this standard update will have on our consolidated financial statements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
     We maintain an investment portfolio consisting mainly of money market funds, commercial paper, corporate obligations, and government obligations with a weighted average maturity of less than one year. These available-for-sale securities are subject to interest rate risk. However, a 10% change in interest rates would not have a material impact to the fair values of these securities at September 30, 2010, primarily due to their short maturity and our intent to hold the securities to maturity. There have been no significant changes subsequent to September 30, 2010.
     The majority of our operations are based in the U.S., and accordingly, the majority of our transactions are denominated in U.S. dollars. However, we have foreign-based operations where transactions are denominated in foreign currencies and are subject to market risk with respect to fluctuations in the relative value of foreign currencies. Our primary foreign currency exposures relate to our short-term intercompany balances with our foreign subsidiaries and accounts receivables valued in the United Kingdom in U.S. dollars. Our primary foreign subsidiaries have functional currencies denominated in the British pound and Euro, and foreign denominated assets and liabilities are remeasured each reporting period with any exchange gains and losses recorded in our consolidated statements of operations. Based on currency exposures existing at September 30, 2010, a 10% movement in foreign exchange rates would not expose us to significant gains or losses in earnings or cash flows. We may use derivative instruments to manage the risk of exchange rate fluctuations. However, at September 30, 2010, we had no outstanding derivative instruments. We do not use derivative instruments for trading or speculative purposes.
Item 4. Controls and Procedures
(a) Evaluation of Disclosure Controls and Procedures
     Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2010. The term “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”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of September 30, 2010, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

(b) Changes in Internal Control over Financial Reporting
     No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the quarter ended September 30, 2010 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
PART II. OTHER INFORMATION
Item 1. Legal Proceedings
     On November 4, 2010, a putative shareholder class action lawsuit was filed in the Court of Chancery in the State of Delaware in and for New Castle County (Cronenwett v. Art Technology Group, Inc. et al) naming our Company and our directors, as well as Oracle Corporation and its wholly-owned subsidiary Amsterdam Acquisition Sub Corporation, as defendants. The complaint seeks to enjoin the proposed acquisition of our Company by Oracle Corporation and alleges claims for breach of fiduciary duty against our directors and for aiding and abetting a breach of fiduciary duty against Oracle Corporation and Amsterdam Acquisition Sub Corporation. The complaint generally alleges that the consideration offered in the proposed transaction is unfair and inadequate. We intend to defend this case vigorously. There can be no assurance, however, that we will be successful in our defense of this action. It is not known when or on what basis the action will be resolved.
     No previously disclosed legal proceedings were terminated during the three months ended September 30, 2010.
Item 1A. Risk Factors
     In addition to the other information set forth in this report, you should carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2009, which could materially affect our business, financial condition or future results. To the best of our knowledge, as of the date of this report there has been no material change in any of the risk factors described in that Annual Report on Form 10-K.
The announcement and pendency of our agreement to be acquired by Oracle could adversely affect our business.
     On November 2, 2010, we entered into a Merger Agreement with Oracle and Amsterdam Acquisition Sub Corporation, a Delaware corporation and wholly-owned subsidiary of Oracle (“Merger Sub”), pursuant to which, subject to satisfaction or waiver of the conditions therein, Merger Sub will merge with us (the “Merger”) with the Company surviving as a wholly-owned subsidiary of Oracle. Subject to the terms of the Merger Agreement, which has been approved by our board of directors and the boards of directors of Oracle and Merger Sub, at the effective time of the Merger (the “Effective Time”), each share of our common stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive $6.00 in cash, without interest. The Merger is conditioned upon, among other things, customary closing conditions. We will continue to operate separately from Oracle until the transaction closes. The announcement and pendency of the Merger, or any significant delay in the consummation of the Merger, could cause disruptions in our business, including affecting our relationship with our customers, vendors and employees, which could have an adverse effect on our business, financial results and operations.
The failure to complete the merger could adversely affect our business.
     There is no assurance that the Merger with Oracle or any other transaction will occur. If the proposed Merger or a similar transaction is not completed, the share price of our common stock may change to the extent that the current market price of our common stock reflects an assumption that a transaction will be completed. In addition, under circumstances defined in the Merger Agreement, we may be required to pay a termination fee of $33.5 million and, in certain circumstances, reimburse reasonable out-of-pocket fees and expenses of Oracle up to $5.0 million incurred with respect to the transactions contemplated by the Merger Agreement. Further, a failed transaction may result in negative publicity and a negative impression of us in the investment community.
In certain instances, the Merger Agreement requires us to pay a termination fee of $33.5 million to Oracle. This payment could affect the decisions of a third party considering making an alternative acquisition proposal to the merger.
     Under the terms of the Merger Agreement, we will be required to pay to Oracle a termination fee of $33.5 million if the Merger Agreement is terminated under certain circumstances. This payment could affect the structure, pricing and terms proposed by a third party seeking to acquire or merge with us and could deter such third party from making a competing acquisition proposal.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds
     On October 27, 2009 our Board of Directors authorized a new stock repurchase program providing for the repurchase of up to $25.0 million of our outstanding common stock in the open market or in privately negotiated transactions, at times and prices considered appropriate depending on the prevailing market conditions. This new authorization is in addition to the remaining $3.9 million under our existing $20 million repurchase program authorized in April of 2007. During the nine months ended September 30, 2010, we repurchased 444,600  shares of our common stock at a cost of $1.5 million. Under the program to date, we have repurchased 7,134,695  shares of our common stock at a cost of $17.6 million.
     Our stock repurchase authorization does not have an expiration date and the pace of our repurchase activity will depend on factors such as our working capital needs, our cash requirements for acquisitions, any debt repayment obligations which may arise, our stock price, and economic and market conditions. Our stock repurchases may be effected from time to time through open market purchases or pursuant to a Rule 10b5-1 plan. Our stock repurchase program may be accelerated, suspended, delayed or discontinued at any time.
     The table below presents information regarding our repurchases of our common stock during the three months ended September 30, 2009.
