ART TECHNOLOGY GROUP, INC.
NOTES TO 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 six months ended June 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) Use of Estimates
     The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Such estimates relate to revenue recognition, the allowance for doubtful accounts, useful lives of fixed assets and identifiable intangible assets, deferred costs, software development costs, accrued liabilities, accrued taxes, deferred tax valuation allowances, and assumptions pertaining to share-based payments. Actual results could differ from those estimates.
     (c) Accounts Receivable
     Accounts receivable represents amounts currently due from customers. Accounts receivable also include $5.9 million and $2.5 million of unbilled accounts receivable at June 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 June 30, 2010, $2.6 million of the $5.9 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.
     ATG records bad debt allowances for accounts receivable based upon a specific review of all outstanding invoices and unbilled accounts receivable, known collection issues, and historical experience. ATG also records a provision for estimated allowances on professional service fees and hosting fees in the same period in which the related revenues are recorded as a reduction to revenue. These estimates are based on historical allowances, analysis of credit memo data, and other known factors and are generally recorded as a reduction in revenue.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
     (d) Revenue Recognition
     ATG derives revenue from the following sources: (1) perpetual software licenses, (2) recurring services, which are comprised of support and maintenance services, application hosting services and Optimization services, and (3) professional and education services. ATG sells certain of these product and service offerings individually or more commonly in multiple element arrangements under various arrangements as follows: 1. Sale of Perpetual Software Licenses and Professional and Education Services, 2. Sale of Application Hosting Services, and 3. Sale of Optimization Services.
     The Company recognizes revenue in accordance with FASB ASC 985-605, Software Revenue Recognition, (“ASC 985-605”), formerly known as AICPA Statement of Position 97-2, Software Revenue Recognition (“SOP 97-2”), or Securities and Exchange Commission Staff Accounting Bulletin No. 104, Revenue Recognition (“SAB 104”), applying the provisions of FASB ASC 605-25, Multiple Element Arrangements, (“ASC 605-25”) formerly known as Emerging Issues Task Force (“EITF”) Issue No. 00-21, Revenue Arrangements with Multiple Deliverables (“EITF 00-21”), depending on the nature of the arrangement.
     Revenue is recognized only when persuasive evidence of an arrangement exists, the fee is fixed or determinable, the product or service has been delivered, and collectability of the resulting receivable is probable. ATG makes significant judgments when evaluating if fees are fixed or determinable and in assessing the customer’s ability to pay for the products or services provided. This judgment is based on a combination of factors, including the contractual terms of the arrangement, completion of a credit check or financial review, payment history with the customer, and other forms of credit evaluation. Upon the completion of these steps and provided all other revenue recognition criteria are met, ATG recognizes revenue consistent with its revenue recognition policies provided below.
     ATG’s standard payment terms are normally within 90 days. The Company in some circumstances provides extended payment terms, and in certain cases considers amounts payable beyond 90 days but less than 12 months to be fixed or determinable. In such cases, judgment is required in evaluating the creditworthiness of the customer and the likelihood of a concession. The Company monitors its ability to collect amounts due under the stated contractual terms of such arrangements and to date has not experienced any concessions to this class of customer. If in the future the Company experiences adverse changes in its ability to collect without concession the amounts due under arrangements involving extended payment terms to this class of customer, it may no longer be able to conclude that such amounts are fixed or determinable and probable of collection, which could adversely affect the Company’s revenue in future periods.
1. Sales of Perpetual Software Licenses and Professional and Education Services
     ATG licenses software under perpetual license agreements and applies the provisions of ASC 985-605. In accordance with said provisions, revenue from software license agreements is recognized when the following criteria are met: (1) execution of a legally binding license agreement, (2) delivery of the software, which is generally through electronic license keys for the software, (3) the fee is fixed or determinable, as determined by the Company’s payment terms, and free of contingencies or significant uncertainties as to payment, and (4) collection is deemed probable by management based on a credit evaluation of the customer. In addition, under multiple element arrangements, to recognize software license revenue up-front, the Company must have vendor specific objective evidence (“VSOE”) of fair value of the undelivered elements in the transaction. The Company’s software license arrangements generally do not include acceptance provisions. However, if conditions for acceptance subsequent to delivery are required, revenue is recognized upon customer acceptance if such acceptance is not deemed to be perfunctory.
     In connection with the sale of its software licenses, ATG sells support and maintenance services, which are recognized ratably over the term of the arrangement, typically one year. Under support and maintenance services, customers receive unspecified software product upgrades, maintenance and patch releases during the term, and internet and telephone access to technical support personnel. Support and maintenance is priced as a percent of the net software license fee and is based on the contracted level of support.

ART TECHNOLOGY GROUP, INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
     Many of the Company’s software arrangements also include professional services for consulting implementation services sold separately under separate agreements. Professional services revenue from these arrangements is generally accounted for separately from the software license because the services qualify as a separate element under ASC 985-605. The more significant factors considered in determining whether professional services revenue should be accounted for separately include the nature of services (i.e. consideration of whether the services are essential to the functionality of the licensed product), degree of risk, availability of services from other vendors, timing of payments, and impact of milestones or acceptance criteria on the realizability of the software license fee. Professional services revenue under these arrangements is generally recognized as the services are performed on a time and materials basis.
     Education revenue, which is recognized as the training is provided to customers, is derived from instructor led training classes either at ATG or onsite at the customer location.
     For software arrangements with multiple elements, the Company applies the residual method in accordance with ASC 985-605. The residual method requires that the portion of the total arrangement fee attributable to the undelivered elements be deferred based on its VSOE of fair value and subsequently recognized as the service is delivered. The difference between the total arrangement fee and the amount deferred for the undelivered elements is recognized as revenue related to the delivered elements, which is generally the software license. VSOE of fair value for all elements in an arrangement is based upon the normal pricing for those products and services when sold separately. The Company has established VSOE of fair value for support and maintenance services, professional services, and education. The Company has not established VSOE for its software licenses, application hosting services or Optimization services. In arrangements that do not include application hosting services or Optimization services, product license revenue is generally recognized upon delivery of the software products.
2. Sales of Application Hosting Services
     ATG derives revenue from application hosting services either from hosting ATG perpetual software licenses purchased by the customer or by providing the software as a service solution to the customer in an arrangement in which the customer does not have the rights to the software license itself but can use the software for the contracted term. In both situations, ATG recognizes application hosting revenue in accordance with ASC 985-605, ASC 605-10, Revenue Recognition, (“ASC 605-10”) and ASC 605-25.
     In accordance with ASC 985-605, these arrangements are generally within the scope of ASC 605-10, and the Company therefore applies the provisions of ASC 605-10 and ASC 605-25, and accounts for the arrangement as a service contract. Pursuant to ASC 605-25, all elements of the arrangement are considered to be one unit of accounting. The elements in these arrangements generally include set-up and implementation services, support and maintenance services, the monthly hosting service and in certain instances a perpetual software license. All fees received up-front under these arrangements, regardless of the nature of the element, are deferred until the application hosting service commences, which is referred to as the “site-delivered” date. Once the site-delivered date has occurred, the up-front fees and hosting service fees are recognized ratably over the hosting period or estimated life of the customer arrangement, whichever is longer. ATG currently estimates the life of the customer arrangement to be four years. In addition, the monthly application hosting service fee is recognized as the application hosting service is provided.
3. Sales of Optimization Services
     ATG derives revenue from Optimization services, which are hosted services enabling ATG’s customers to provide click-to-call, click-to-chat and recommendations services to their customers. Optimization services are site-independent and are not required to be used in conjunction with ATG’s software products. These services are a stand-alone independent service solution, which are typically contracted for a one-year term. The Company recognizes revenue on a monthly basis as the services are provided. Fees are generally based on monthly minimums and transaction volumes. In certain instances Optimization services are bundled with ATG software arrangements, which typically include perpetual software licenses, support and maintenance services and professional services for the perpetual software license. In these situations the Company accounts for the arrangements in accordance with ASC 985-605. The Company does not have VSOE of fair value for Optimization services, and as a result, the up-front fees received under the arrangement regardless of the nature of the element are deferred and recognized ratably

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
over the period of providing the Optimization services, provided that the professional services, if applicable, have commenced.
     In certain instances, the Company sells perpetual software licenses with application hosting services and Optimization services. In these situations the Company accounts for the arrangements in accordance with ASC 605-10. All elements in the arrangement for which the Company receives up-front fees are recognized as revenue ratably over the period of providing the related service or estimated life of the customer arrangement, whichever is longer.
     The Company allocates and classifies revenue in its statement of operations based on its evaluation of VSOE of fair value, or an estimate of fair value when VSOE has not been established, for each applicable element of the transaction: professional services, support and maintenance services, application hosting services, and/or Optimization services. ATG uses the residual method to determine the amount of revenue to allocate to product license revenue. The fee for each element is recognized ratably, and as such, a portion of software license revenue recorded in the statement of operations is from these ratably recognized arrangements.
     (e) 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     Six Months Ended  
    June 30,     June 30,  
    2010     2009     2010     2009

Unrealized gain (loss) on available-for-sale securities
    (96 )     65       (215 )     116  
 
                       
Total comprehensive income
  $ 3,502     $ 5,637     $ 5,017     $ 8,350  
 
                       
     (f) Concentrations of Credit Risk and Major Customers
     Financial instruments that potentially subject ATG to concentrations of credit risk consist principally of marketable securities and accounts receivable. ATG maintains cash, cash equivalents and marketable securities with durations of twenty-three months or less.
     The Company sells its products and services to customers in a variety of industries, including consumer retail, financial services, manufacturing, communications and technology, travel, and media and entertainment. The Company has credit policies and standards and routinely assesses the financial strength of its customers through continuing credit evaluations. The Company generally does not require collateral or letters of credit from its customers.
     At June 30, 2010 and 2009 two customers and one customer respectively accounted for more than 10% of accounts receivable. Furthermore, one customer accounted for more than 10% of revenues for the three month period ended June 30, 2010 and no customers accounted for more than 10% of revenues for the three month period ended June 30, 2009 or the six month periods ended June 30, 2010 and 2009.

     (g) 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.
     In January 2010, the FASB issued ASU 2010-06, Fair Value Measurements and Disclosures: Improving Disclosures about Fair Value Measurements, which amends ASC 820-10, Fair Value Measurements and Disclosures. ASU 2010-06 requires additional disclosures for transfers in and out of Levels 1 and 2 fair value classifications and for activity in Level 3 and clarifies certain other existing disclosure requirements. It also clarifies existing fair value disclosures regarding the level of disaggregation and the inputs and valuation techniques used to measure fair value. The Company adopted ASU 2010-06 beginning January 15, 2010. This adoption had no impact on the Company’s financial position, results of operations or cash flows.
(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):

(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 three months ended June 30, 2010 and 2009 and related weighted average assumptions is as follows:
                 
    Six Months Ended June 30,
Stock Options   2010   2009
Options granted (in thousands)
    1,593       832  
Weighted-average exercise price
  $ 4.45     $ 2.48  
Weighted-average grant date fair value
  $ 2.81     $ 1.62  
Assumptions:
               
Expected volatility
    66.07 %     71.36 %
Expected term (in years)
    6.25       6.25  
Risk-free interest rate
    2.65 %     1.98 %
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% to all unvested options as of June 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.

(1)   In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. Options expected to vest are calculated by applying an estimated forfeiture rate to the unvested options.
     During the six months ended June 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 $1.0 million and $0.6 million, respectively, and the total amount of cash received by the Company from exercise of these options was $1.1 million and $0.5 million, respectively.
     Restricted Stock Awards
     A summary of the Company’s restricted stock and restricted stock unit (“RSU”) award activity for the six months ended June 30, 2010 is presented below:
                 
            Weighted
            Average Grant
    Restricted Stock   Date Fair Value
    and RSUs   Per Share

Restrictions lapsed
    (1,763 )     2.88  
Awards forfeited
    (181 )     2.94  
     
Non-vested shares outstanding at June 30, 2010
    6,192       3.31  
     
     During the six months ended June 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 June 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 June 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 June 30, 2010, the achievement of this additional condition is not deemed probable by the Company.

     As of June 30, 2010, there was $23.3 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 2.2 years.
     The Company recorded total stock-based compensation expense of $2.5 million and $2.4 million respectively, for the three months ended June 30, 2010 and 2009 and $4.9 million and $4.4 million respectively, for the six 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 $13.4 million and $14.7 million for the three months ended June 30, 2010 and 2009, respectively and $25.1 million and $25.4 million for the six months ended June 30, 2010 and 2009 respectively. Revenues from foreign sources were primarily generated from customers located in Europe and the Asia/Pacific region. All of the Company’s product sales for the three and six months ended June 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 six month periods ended June 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 June 30, 2010, the Company’s marketable securities had a fair value of $137.2 million, amortized cost of $137.4 million, and unrealized loss recorded in other comprehensive income of $0.2 million. In addition, 82% of the marketable securities held by the Company at June 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 June 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 June 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) Restructuring
     During the three month period ended June 30, 2010, the Company recorded a one time charge of $0.4 million to exit a lease and write off certain assets acquired as part of the InstantService acquisition. The leased facility and associated assets were located in an area where the Company already had established office space. This was a one-time charge and is not associated with any ongoing Company-wide restructuring plan.
(9) 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.
(10) 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, which will continue to be amortized, consisted of the following (in thousands):

     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 June 30, 2010 and 2009, respectively and $2.4 million and $1.9 million for the six-month periods ended June 30, 2010 and 2009 respectively.

(11) 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 June 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 income tax provision in the amount of $0.4 million and income tax benefit of $0.4 million for the three and six months ended June 30, 2010, respectively, related to the U.S. alternative minimum tax (“AMT”) state and foreign income taxes as well as interest related to uncertain tax positions. The utilization of tax loss carryforwards is limited in the calculation of AMT and, as a result, a federal tax charge was recorded in the three and six months ended June 30, 2010 and 2009. The AMT liability is available as a credit against future tax obligations upon the full

utilization or expiration of the Company’s net operating loss carryforward. Included in the $0.4 million benefit for the six months ended June 30, 2010 is approximately $1.1 million related to the reversal of the valuation allowance on certain deferred tax assets as described below.
     For the three and six months ended June 30, 2009, the Company recorded income tax provisions of $0.6 million and $0.9 million, respectively, which related to foreign taxes on earnings in certain of the Company’s foreign subsidiaries as well as interest and penalties related to uncertain tax positions.
     During the quarter ended March 31, 2010, the Company recorded net deferred tax liabilities of approximately $1.1 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 $1.1 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.
(12) 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 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. Discovery in the LivePerson action has not yet commenced. 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.
     The Company’s industry is characterized by the existence of a large number of patents, trademarks and copyrights, and by increasingly frequent litigation based on allegations of infringement or other violations of intellectual property rights. Some of the Company’s competitors in the e-commerce software and services market have filed or may file patent applications covering aspects of their technology that they may claim the Company’s technology infringes. Such competitors could make claims of infringement against the Company with respect to the Company’s products and technology. Additionally, third parties who are not actively engaged in providing e-commerce products or services but who hold or acquire patents upon which they may allege the Company’s current or future products or services infringe may make claims of infringement against the Company or the Company’s customers. The Company’s agreements with its customers typically require it to indemnify them against claims of intellectual property infringement resulting from their use of the Company’s products and services with certain industry-standard exceptions. The Company periodically receives notices from customers regarding patent license inquiries they have received which may or may not implicate the Company’s indemnity obligations, and certain of its customers are currently parties to litigation in which it is alleged that the patent rights of others are infringed by the Company’s products or services. Any litigation over intellectual property rights, whether brought by the Company or by others, could result in the expenditure of significant financial resources and the diversion of management’s time and efforts. In addition,

litigation in which the Company or its customers are accused of infringement might cause product shipment or service delivery delays, require the Company to develop alternative technology or require the Company to enter into royalty or license agreements, which might not be available on acceptable terms, or at all. ATG could incur substantial costs in prosecuting or defending any intellectual property litigation. These claims, whether meritorious or not, could be time consuming, result in costly litigation, require expensive changes in the Company’s methods of doing business or could require the Company to enter into costly royalty or licensing agreements, if available. As a result, these claims could harm the Company’s business.
     The ultimate outcome of any litigation is uncertain, and either unfavorable or favorable outcomes could have a material negative impact on the Company’s financial position, results of operations, consolidated balance sheets and cash flows, due to defense costs, diversion of management resources and other factors.

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.
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

19


Table of Contents

ART TECHNOLOGY GROUP, INC.
future financial performance that excludes amounts that are included in the most directly comparable measure 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 weak economy. As recovery from the recent global recession progresses, its impact across all sectors of the U.S. and most foreign economies continues to create substantial uncertainty for our business. These weakened economic conditions have led to delays or reductions in capital spending, including purchases of information technology across industries and markets, and some customers in markets that we serve, such as luxury retailers, have been particularly affected. We cannot accurately predict the duration or severity of the current uncertainty regarding economic conditions or its specific impact on our customers’ 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 is growing 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 in light of current uncertain economic conditions 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 27% for the three and six months ended June 30, 2010 compared to 27% and 30% for the three and six months ended June 30, 2009. The primary driver of the decrease in foreign source revenues as a percentage of total revenues compared to similar periods in the prior year is the addition of the InstantService business acquired January 8, 2010. InstantService’s customer portfolio is primarily US based. 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, as well as increased competition from smaller competitors entering this market. 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 believe the following critical accounting policies are those that are most important to the portrayal of our results of operations and financial condition and that require the most subjective judgment.
Revenue Recognition
     We generate revenue through the sale of perpetual software licenses, recurring services, which are comprised of support and maintenance services, application hosting services, Optimization services, and professional and education services. Please refer to the notes to the condensed consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q for a more comprehensive discussion of our revenue recognition policy.
     Our policy is to recognize revenue when the applicable revenue recognition criteria have been met, which generally include the following:
     Persuasive evidence of an arrangement — We use a legally binding contract signed by the customer as evidence of an arrangement. We consider the signed contract to be the most persuasive evidence of the arrangement.
     Delivery has occurred or services rendered — Software and the corresponding access keys are generally delivered to customers electronically. Electronic delivery occurs when we provide the customer access to the software. Our software license agreements generally do not contain conditions for acceptance. Our support and maintenance services, Optimization services, and application hosting services are delivered on a monthly basis. Professional services are generally delivered on a time and material basis.
     Fee is fixed or determinable — We assess whether the fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the transaction. Our standard payment terms are normally within 90 days. In some circumstances we provide extended payment terms, and in certain cases consider amounts payable beyond 90 days but less than 12 months to be fixed or determinable. Significant judgment is involved in assessing whether a fee is fixed or determinable. Our experience has been that we are generally able to determine whether a fee is fixed or determinable.
     Our standard payment terms are normally within 90 days. In some circumstances we provide extended payment terms, and in certain cases we consider amounts payable beyond 90 days but less than 12 months to be fixed or determinable. In such cases, judgment is required in evaluating the creditworthiness of the customer and the likelihood of a concession. We monitor our ability to collect amounts due under the stated contractual terms of such arrangements and to date we have not experienced any material concessions to this class of customer. Significant

judgment is involved in assessing whether a contractual amendment constitutes a concession. If in the future we experience adverse changes in our ability to collect without concession the amounts due under arrangements involving extended payment terms to this class of customer, we may no longer be able to conclude that such amounts are fixed or determinable and probable of collection, which could adversely affect our revenue in future periods.
     Collection is probable — We assess the probability of collection from each customer at the outset of the arrangement based on a number of factors, including the customer’s payment history and its current creditworthiness. If in our judgment collection of a fee is not probable, we do not record revenue until the uncertainty is removed, which generally means revenue is recognized upon our receipt of the cash payment. Our experience has been that we are generally able to estimate whether collection is probable.
     Generally we enter into arrangements that include multiple elements. Such arrangements may include sales of software licenses and related support and maintenance services in conjunction with application hosting services, Optimization services or professional and/or education services. In these situations we must determine whether the various elements meet the applicable criteria to be accounted for as separate elements. If the elements cannot be separated, revenue is recognized once the revenue recognition criteria for the entire arrangement have been met or over the period that our obligations to the customer are fulfilled, as appropriate. If the elements are determined to be separable, revenue is allocated to the separate elements based on VSOE of fair value and recognized separately for each element when the applicable revenue recognition criteria for each element have been met. In accounting for these multiple element arrangements, we must make determinations about whether elements can be accounted for separately and make estimates regarding their relative fair values.
     Recording revenue from arrangements that include application hosting services requires us to estimate the expected life of the customer arrangement. Pursuant to the application of relevant GAAP literature, ASC 605-25, Multiple Element Arrangements, our arrangements with application hosting services are accounted for as one unit of accounting. In such situations, we recognize the entire arrangement fee ratably over the term of the estimated life of the customer arrangement. Based on our historical experience with our customers, we estimate the life of the typical customer arrangement to be approximately four years.
     Our VSOE of fair value for certain elements of an arrangement is based upon the pricing in comparable transactions when the element is sold separately. VSOE of fair value for support and maintenance is based upon our history of charging our customers stated annual renewal rates. VSOE of fair value for professional services and education services is based on the price charged when the services are sold separately. Annually, we evaluate whether or not we have maintained VSOE of fair value for support and maintenance services and professional services. We have concluded that we have maintained VSOE of fair value for both support and maintenance services and professional services because the majority of our support and maintenance contract renewal rates and professional service rates per personnel level fall in a narrow range of variability within each service offering.
     For multiple element arrangements, VSOE of fair value must exist to allocate the total arrangement fee among all delivered and undelivered elements of a perpetual license arrangement. If VSOE of fair value does not exist for all elements to support the allocation of the total fee among all delivered and undelivered elements of the arrangement, revenue is deferred until such evidence does exist for the undelivered elements, or until all elements are delivered, whichever is earlier. If VSOE of fair value of all undelivered elements exists but VSOE of fair value does not exist for one or more delivered elements, revenue is recognized using the residual method. Under the residual method, the VSOE of fair value of the undelivered elements is deferred, and the remaining portion of the arrangement fee is recognized as revenue as the elements are delivered.
     We also sell perpetual software licenses with application hosting services and/or Optimization services. We do not have VSOE of fair value for either of these services. In these situations all elements in the arrangement for which we receive up-front fees, which typically include perpetual software fees, support and maintenance fees, and set-up and implementation fees, are recognized as revenue either ratably over the period of providing the application hosting service or Optimization services, or ratably over the longer of the service period or estimated customer life, depending on the elements included in the arrangement. We allocate and classify revenue in our statement of operations based on our evaluation of VSOE of fair value, or a proxy of fair value thereof, available for each

23

applicable element of the transaction. We generally base our proxy of fair value on arms-length negotiations for the contracted elements. This allocation methodology requires judgment and is based on our analysis of our sales transactions.
Allowances for Accounts Receivable
     We maintain allowances for estimated losses resulting from the inability of our customers to make required payments. We perform credit reviews of each customer, monitor collections and payments from our customers, and determine the allowance based upon historical experience and specific customer collection issues. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances would be required. In addition, we record allowances to revenue based on past credit memo history.
Research and Development Costs
     We account for research and development costs for our software products that we license to our customers in accordance with ASC 730-10, Accounting for Research and Development Costs, and ASC 985-20, Accounting for the Costs of Computer Software to be Sold, Leased, or Otherwise Marketed, which specifies that costs incurred internally to develop computer software products should be charged to expense as incurred until technological feasibility is reached for the product. Once technological feasibility is reached, all software costs should be capitalized until the product is made available for general release to customers. Judgment is required in determining when technological feasibility is established. We believe that the time period from reaching technological feasibility until the time of general product release is very short. Costs incurred after technological feasibility is reached are not material, and accordingly, all such costs are charged to research and development expense as incurred.
     Costs incurred to develop software applications used internally in our Optimization services are accounted for in accordance with ASC 350-10, Accounting for Computer Software Developed or Obtained for Internal Use. Our capitalized costs include certain external direct costs of materials and services incurred in developing or obtaining internal-use computer software and payroll and payroll-related costs for employees who are directly associated with, and who devote time to, the project. These costs generally consist of internal labor during configuration, coding, and testing activities. Costs incurred during the preliminary project stage or costs incurred for data conversion activities, training, maintenance, and general and administrative or overhead costs are expenses as incurred. Costs that cannot be separated between maintenance of, and relatively minor upgrades and enhancements to, internal-use software are also expensed as incurred. Capitalization begins when the preliminary project stage is complete, management with the relevant authority authorizes and commits to the funding of the software project, it is probable the project will be completed, the software will be used to perform the functions intended, and certain functional and quality standards have been met. We evaluate any capitalized costs for impairment whenever conditions or events indicate that the carrying amount of the asset may not be recoverable.
Impairment or Disposal of Long Lived Assets, including Intangible Assets
     We review our long-lived assets, including intangible assets subject to amortization, whenever events or changes in circumstances indicate that the carrying amount of such an asset may not be recoverable. Recoverability of these assets is measured by comparison of their carrying amount to the future undiscounted cash flows the assets are expected to generate. If such assets are considered impaired, the impairment to be recognized is equal to 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. In assessing recoverability, we must make assumptions regarding estimated future cash flows and discount factors. If these estimates or related assumptions change in the future, we may be required to record impairment charges. Intangible assets with determinable lives are amortized over their estimated useful lives, based upon the pattern in which the expected benefits will be realized, or on a straight-line basis, whichever is greater. We did not record any impairment charges in any of the periods presented.

Goodwill
     Goodwill represents the excess of the purchase price over the fair value of net tangible and intangible assets acquired in a business combination. In accordance with ASC 350-10, Goodwill and Other Intangible Assets, we evaluate goodwill for impairment annually on December 1, as well as whenever events or changes in circumstances suggest that the carrying amount may not be recoverable. Because we have one reporting segment under ASC 350-10, we utilize the entity-wide approach for assessing goodwill for impairment and compare our market value to our net book value to determine if impairment exists. No impairment of goodwill resulted from our evaluation of goodwill in any of the periods presented, however in the future these impairment tests may result in impairment losses that could have a material adverse impact on our results of operations.
Accounting for Income Taxes
     In connection with preparing our financial statements, we are required to compute income tax expense in each jurisdiction in which we operate. This process requires us to project our current tax liability and estimate our deferred tax assets and liabilities, including net operating loss and tax credit carryforwards. We also are required to assess the need for a valuation allowance against deferred tax assets. As part of this assessment, we have considered our recent operating results, future taxable income projections, and all prudent and feasible tax planning strategies.
     As of June 30, 2010 we maintained a full valuation allowance against our U.S. net deferred tax assets. We currently believe that we have not sustained profitability in amounts that are sufficient to support a conclusion that a valuation allowance is no longer required. We believe there is significant uncertainty in our future profits due to the growing breadth of our product mix and the effect that can have on the timing of revenue recognition, and the related effect on U.S. reported income. Specifically, we may be required to defer the recognition of revenue in amounts greater than we are currently projecting. Assuming that, among other factors of positive and negative evidence, we meet our estimates of 2010 forecasted earnings, we may release a portion of our U.S. valuation allowance during the second half of 2010, which is consistent with the timing of our annual forecasting exercise. Additionally, in connection with our January 2010 acquisition of InstantService, we assessed the acquired deferred tax assets and liabilities and we released a portion of our valuation allowance amounting to approximately $1.1 million as a result of acquired net deferred tax liabilities. The release of the valuation allowance was recorded as a tax benefit in our statement of operations in accordance with ASC 805, Business Combinations.
     As of June 30, 2010, there was no change in our valuation allowance analysis relating to the deferred tax assets in certain foreign jurisdictions. We continue to believe that the deferred tax assets would more likely than not be realized based upon our expected future results from operations in these jurisdictions.
     We account for our uncertain tax positions in accordance with ASC 740-10, Income Taxes. During the quarter ended June 30, 2010, there was no change in our gross liability for unrecognized tax benefits. As of June 30, 2010 we have recorded less than $0.1 million of interest and penalties in our statement of operations and have accrued approximately $0.1 million of potential interest and penalties 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.
Stock-Based Compensation Expense
     We account for stock-based compensation in accordance with ASC 718-10, Compensation — Stock Compensation. Under the fair value recognition provisions of ASC 718-10, stock-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the vesting period. We use the Black-Scholes option pricing model to estimate the fair value of our stock option awards. Estimating the fair value of stock-based awards at the grant date requires judgment, including estimating the expected life of the stock awards and the volatility of our underlying common stock. Changes to the assumptions may have a significant impact on the fair value of stock options, which could have a material impact on our financial statements. In addition, judgment is also required in estimating the amount of stock-based awards that are expected to be forfeited. Should our actual forfeiture rates differ significantly from our estimates, our stock-based compensation expense and results of operations could be materially impacted.

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 licenses revenue, as reported under GAAP, our product license bookings for the periods presented:

     Product license bookings increased $1.6 million, or 9.5%, to $18.2 million and increased $3.1 million, or 10.6% to $32.0 million in the three and six months ended June 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 31.0% and 44.0% of our total product license bookings for the three months ended June 30, 2010 and 2009 respectively and 34.0% and 41.4% respectively for the six 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 $3.8 million and $4.3 million for the three month periods ended June 30, 2010 and 2009 respectively and $8.0 million and $9.5 million respectively for the six month periods then ended. All of the aforementioned amounts were recognized upon the resolution of contractual conditions or other conditions that required their initial deferral.
     We expect third quarter 2010 product license bookings growth to be in the range of an 8% to 12% increase over the third quarter of 2009. We are currently forecasting that approximately 20% to 30% of our product license bookings will be deferred and recognized ratably and approximately $3.0 will be recognized from previously deferred license revenue.

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 $9.5 million, or 12.8%, product license and recurring services revenues, which was partially offset by a decrease of $2.0 million, or 15.0%

in professional and education services. Information on revenue changes, by type, for the three and six month periods ended June 30, 2010 compared to the same periods in 2009 is provided below.
     Revenue generated from international customers decreased to $13.4 million from $14.7 million of total revenue during the three months ended June 30, 2010 when compared to the same period in 2009. In both the three month periods ended June 30, 2010 and 2009 revenue generated from international customers represented 27% of total revenues. International revenue also decreased to $25.1 million, or 27% of total revenue from $25.4 million, or 30% of total revenue respectively for the six month periods ended June 30, 2010 and 2009. The primary driver of the decrease in foreign source revenues as a percentage of total revenues compared to similar periods in the prior year is the addition of the InstantService business acquired January 8, 2010, as InstantService’s customer portfolio is primarily US based.
     During the three month period ended June 30, 2010, one customer accounted for more than 10% of total revenues and no customer accounted for more than 10% of revenues for the three month period ended June 30, 2009 or the six month periods ended June 30, 2010 and 2009.
     We expect third quarter 2010 revenues to be in the range of $47.0 million to $49.0 million.

     Product license revenue increased $2.8 million, or 20.4%, to $16.4 million and increased $2.7 million, or 10.2% to $29.2 million in the three and six months ended June 30, 2010, respectively, when compared to the same periods in 2009. The increase experienced in the three months ended June 30, 2010 compared to the same period in 2009 is based on an increase in product license bookings of $1.6 million and a decrease in product license deferred revenue of $1.7 million offset by a decrease in the recognition of previously deferred product license revenue of $0.5 million. The increase experienced in the six months ended June 30, 2010 compared to the same period in 2009 is based on an increase in product license bookings of $3.1 million and a decrease in product license deferred revenue of $1.1 million offset by a decrease in the recognition of previously deferred product license revenue of $1.5 million. As noted above, 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 $4.4 million and $7.3 million respectively for the three and six months ended June 30, 2010 compared to $3.8 million and $10.5 million respectively for the same periods in 2009.
     We expect product license revenues to be in the range of $11.0 million to $12.0 million in the third quarter of 2010.

     Our recurring services revenue increased $3.2 million, or 13.2%, to $27.2 million and increased $6.7 million, or 14.3% to $53.9 million respectively in the three and six months ended June 30, 2010 when compared to the same periods in 2009, as follows:
    Support and maintenance revenue increased $1.1 million, or 8.9%, to $13.2 million and increased $2.6 million, or 11.0% to $26.1 million respectively in the three and six months ended June 30, 2010 when compared to the same periods in 2009 primarily based on continued renewal rates in excess of 90% and growth in our installed base of ATG e-commerce software.
 
    e-Commerce optimization services and managed application hosting services revenue increased $2.1 million, or 17.6%, to $14.0 million and increased $4.2 million, or 17.6% to $27.8 million respectively in the three and six months ended June 30, 2010 when compared to the same periods in 2009 primarily based on the inclusion of the revenues of InstantService 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 $6.5 million and $13.3 million respectively for the three and six months ended June 30, 2010 compared to $6.8 million and $12.6 million respectively for the same periods in 2009.
     We expect recurring services revenue to be in the range of $29.0 million to $30.0 million in the third quarter of 2010.

     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 $1.2 million, or 17.9%, to $5.6 million and decreased $1.9 million, or 15.0% to $10.8 million respectively in the three and six months ended June 30, 2010 when compared to the same periods in 2009, primarily due to the winding down of the government funded research business that we acquired with CleverSet in 2008.
     Professional services and education revenue generated from international customers was $2.5 million and $4.5 million respectively for the three and six months ended June 30, 2010 compared to $1.3 million and $3.2 million respectively for the same periods in 2009.
     We expect professional and education services revenue to be in the range of $6.0 million to $7.0 million in third quarter of 2010.

     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 $1.7 million, or 17.6%, to $17.0 million and increased $4.4 million, or 13.3% to $33.9 million respectively in the three and six months ended June 30, 2010 when compared to the same periods in 2009. The increase in cost of recurring services in the three and six month periods in 2010 is primarily due to increased salary and benefit related costs.
     We expect third quarter 2010 recurring services gross margin to be in the low 60% range.

     Cost of professional and education services revenues 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 $0.7 million, or 12.7%, to $4.8 million and decreased $1.2 million, or 10.7% to $9.6 million respectively in the three and six months ended June 30, 2010 when compared to the same periods in 2009. The decrease in cost of professional and education services in the three and six month periods in 2010 primarily relates to increases in costs deferred on multiple element arrangements that will not be recorded until recognition of revenue commences, of $1.5 million and $2.4 million respectively in the three and six month periods ended June 30, 2010 over the same periods in 2009. These were partially offset by an increase in salary and benefit related costs of $0.3 million and $0.5 million respectively in the three and six month periods ended June 30, 2010 compared to the same periods in 2009.
     We expect third quarter 2010 professional and education services gross margin to be 5% to 10%.

     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 $0.5 million, or 6.3%, to $8.2 million and increased $1.7 million, or 11.1% to $16.8 million in the three and six months ended June 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 consistent. The increase for the three month period ended June 30, 2010 compared to the same period in 2009 is primarily related to increases in salary and benefit expenses of $0.7 million offset by a credit of $0.3 million received in a grant from the government of the United Kingdom as part of their Invest in Northern Ireland program as well as greater capitalization of costs over the prior year. Increases in salary and benefits were a result of increased headcount over the prior year. The increase for the six month period ended June 30, 2010 compared to the same period in 2009 primarily relates to increases in salary and benefit expenses of $1.5 million offset by the aforementioned $0.3 received from the government of the United Kingdom.
     During the three and six month periods ended June 30, 2010, we capitalized $0.4 million and $0.6 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 $0.2 million and $0.3 million respectively during the same periods in 2009.

     Sales and marketing expenses increased $2.9 million, or 23.2%, to $15.5 million and increased $5.1 million, or 20.3% to $29.9 million in the three and six months ended June 30, 2010, respectively, when compared to the same periods in 2009. Over the same periods, sales and marketing expenses as a percentage of total revenue increased 3.0% compared to the three and six month periods in the prior year. The increase for the three month period ended June 30, 2010 compared to the same period in 2009 is primarily related to increases in salary and benefit expenses, primarily driven by commissions due to higher bookings, of $1.7 million and $0.4 million in travel related expenses. The increase for the six month period ended June 30, 2010 compared to the same period in 2009 primarily relates to increases in salary and benefit expenses, primarily driven by commissions due to higher bookings, of $2.8 million, $0.7 million in travel related expenses and $0.6 million in marketing costs.

     General and administrative expenses increased $0.4 million, or 9.5%, to $5.1 million and increased $1.0 million, or 11.8% to $10.2 million in the three and six months ended June 30, 2010, respectively, when compared to the same periods in 2009. Over the same periods, general and administrative expenses as a percentage of total revenues remained relatively stable at 10-11%. The increase for the three month period ended June 30, 2010 compared to the same period in 2009 is primarily related to an increase in salary and benefit expenses of $0.5 million and the increase for the six month period ended June 30, 2010 compared to the same period in 2009 primarily relates to increases in salary and benefit expenses of $1.1 million.
     We expect total operating expenses to be in the range of $28.0 million to $29.0 million in the third quarter of 2010.
Stock-Based Compensation Expense
     Stock-based compensation expense was $2.4 million for both three month periods ended June 30, 2010 and 2009 and was $4.9 million and $4.4 million for the six month periods ended June 30, 2010 and 2009 respectively, and is reflected in our costs and expenses above based on the function of the relevant personnel. As of June 30, 2010, the total compensation cost related to unvested awards not yet recognized in the statement of operations was approximately $23.3 million, which will be recognized over a weighted average period of approximately 2.2 years.
     We expect stock-based compensation expense to be approximately $3.0 million in the third quarter of 2010.
Interest and Other (Expense) Income, Net
     Interest and other income, net was $0.1 million and $0.3 million for the three months ended June 30, 2010 and 2009 respectively and $(0.2) million and $0.6 million for the six months ended June 30, 2010 and 2009 respectively. The decreases realized for both the three and six month periods compared to the same periods in 2009 primarily related to unfavorable changes in foreign exchange rates.

Provision for Income Taxes
     The income tax provision in the amount of $0.4 million and income tax benefit of $0.4 million for the three and six months ended June 30, 2010, respectively, related to the U.S. alternative minimum tax (“AMT”) state and foreign income taxes as well as interest related to uncertain tax positions. The utilization of tax loss carryforwards is limited in the calculation of AMT and, as a result, a federal tax charge was recorded in the three and six months ended June 30, 2010 and 2009. The AMT liability is available as a credit against future tax obligations upon the full utilization or expiration of our net operating loss carryforward. Included in the $0.4 million benefit for the six months ended June 30, 2010 is approximately $1.1 million related to the reversal of the valuation allowance on certain deferred tax assets as described below.
     For the three and six months ended June 30, 2009, we recorded income tax provisions of $0.6 million and $0.9 million, respectively, which related to foreign taxes on earnings in certain of our foreign subsidiaries as well as interest and penalties related to uncertain tax positions.
     During the quarter ended March 31, 2010, we recorded net deferred tax liabilities of approximately $1.1 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 $1.1 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.
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 June 30, 2010 were our cash, cash equivalents, short and long-term marketable securities of $171.0 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 $17.6 million for the six months ended June 30, 2010, an increase of $4.6 million compared to the same period in the prior year. This difference is primarily driven by an increase in cash inflows related to deferred revenue of $12.7 million to $13.4 million compared to $0.7 million in the six months ended June 30, 2009 being offset by increased cash outflows related to deferred costs, accounts payable and prepaid and other assets over the same periods of $2.8 million, $4.1 million and $2.8 million respectively. The increase in deferred revenue is being driven by improved renewal rates for support maintenance contracts and the entrance into certain hosting contracts and professional service engagements during the six months ended June 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 payment of rent and information technology related support fees during the six months ended June 30, 2010 coupled with the recording of $1.4 million in interest receivable related to our portfolio of marketable securities.
     Net cash used in investing activities was $129.3 million for the six months ended June 30, 2010, an increase of $126.1 million compared to the six months ended June 30, 2009. The difference is primarily driven by a net cash outflow in purchases/settlements of marketable securities of $106.7 million as a result of cash raised from our equity offering coupled with a cash outflow of $15.2 million related to our acquisition of InstantService, net of cash acquired.
     Net cash provided by financing activities was $92.9 million for the six months ended June 30, 2010, an increase of $92.7 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 being offset by cash outflows related to repayment of debt acquired as part of the purchase of InstantService and increased payment of employee withholding taxes related to RSU vesting in the amounts of $1.6 million and $1.3 million respectively.

     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.
     We expect third quarter 2010 cash flow from operations to be in the range of $8.0 million to $10.0 million.
     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 six months ended June 30, 2010 and 2009, we repurchased no shares of our common stock. For the life of the stock repurchase program through June 30, 2010, we have repurchased 6,690,095 shares of its common stock at a cost of $16.1 million
Accounts Receivable and Days Sales Outstanding
     Information about our accounts receivable balance and days sales outstanding for the quarters ended June 30, 2010 and December 31, 2009 is as follows:
                 
    As of and for the
    Quarter Ended
    June 30,   December 31,
    2010   2009
    (In thousands)
Days sales outstanding
    82       75  
Revenue
  $ 49,163     $ 49,663  
Accounts receivable, net
  $ 44,963     $ 41,522  
Percent of accounts receivable less than 60 days
    96 %     97 %
     We evaluate our performance on collections on a quarterly basis. As of June 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.
     In January 2010, the FASB issued ASU 2010-06, Fair Value Measurements and Disclosures: Improving Disclosures about Fair Value Measurements, which amends ASC 820-10, Fair Value Measurements and Disclosures. ASU 2010-06 requires additional disclosures for transfers in and out of Levels 1 and 2 fair value classifications and for activity in Level 3 and clarifies certain other existing disclosure requirements. It also clarifies existing fair value disclosures regarding the level of disaggregation and the inputs and valuation techniques used to measure fair value. We adopted ASU 2010-06 beginning January 15, 2010. This adoption had no impact on our financial position, results of operations or cash flows.

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 June 30, 2010 and December 31, 2009 primarily due to their short maturity and our intent to hold the securities to maturity. There have been no significant changes subsequent to June 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 June 30, 2010 and December 31, 2009, 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 June 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 June 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 June 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 June 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
     As previously disclosed, in December 2001, a purported class action complaint was filed against our 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 undisclosed compensation in connection with Primus’ initial public offering. The litigation has been coordinated in

ART TECHNOLOGY GROUP, INC.
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 we cannot predict the outcome of the litigation, we do not expect any material adverse impact to our business, or the results of our 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, we joined the action and filed counter claims against LivePerson, alleging that LivePerson infringes two of our patents and we are seeking injunctive relief, damages and attorneys fees against LivePerson. Discovery in the LivePerson action has not yet commenced. We are investigating the claims made by LivePerson and have reached no conclusion as to the likelihood of an adverse outcome in the litigation, which we intend to contest vigorously.
     Our industry is characterized by the existence of a large number of patents, trademarks and copyrights, and by increasingly frequent litigation based on allegations of infringement or other violations of intellectual property rights. Some of our competitors in the market for e-commerce software and services have filed or may file patent applications covering aspects of their technology that they may claim our technology infringes. Such competitors could make claims of infringement against us with respect to our products and technology. Additionally, third parties who are not actively engaged in providing e-commerce products or services but who hold or acquire patents upon which they may allege our current or future products or services infringe may make claims of infringement against us or our customers. Our agreements with our customers typically require us to indemnify them against claims of intellectual property infringement resulting from their use of our products and services with certain industry-standard exceptions. We periodically receive notices from customers regarding patent license inquiries they have received which may or may not implicate our indemnity obligations, and certain of our customers are currently parties to litigation in which it is alleged that the patent rights of others are infringed by our products or services. Any litigation over intellectual property rights, whether brought by us or by others, could result in the expenditure of significant financial resources and the diversion of management’s time and efforts. In addition, litigation in which we or our customers are accused of infringement might cause product shipment or service delivery delays, require us to develop alternative technology or require us to enter into royalty or license agreements, which might not be available on acceptable terms, or at all. We could incur substantial costs in prosecuting or defending any intellectual property litigation. These claims, whether meritorious or not, could be time consuming, result in costly litigation, require expensive changes in our methods of doing business or could require us to enter into costly royalty or licensing agreements, if available. As a result, these claims could harm our business.
     The ultimate outcome of any litigation is uncertain, and either unfavorable or favorable outcomes could have a material negative impact on our results of operations, consolidated balance sheets and cash flows, due to defense costs, diversion of management resources and other factors.
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.

Item 4. (Reserved)
Item 5. Other Information
Compensatory Arrangements of Certain Officers
     At our annual meeting of stockholders on May 24, 2010, our stockholders approved amendments to the Amended and Restated 1996 Stock Option Plan (the “1996 Plan”), in which our executive officers are entitled to participate. As more fully set forth in our definitive proxy materials for the meeting, the principal purposes of the amendments were to:
    Increase the number of shares issuable under the 1996 Plan by 14,000,000 shares;
 
    Alter the ratio within the 1996 Plan that determines how full value awards, such as grants of restricted stock, are counted against the number of shares reserved for issuance under the plan, which we refer to as the “fungibility ratio,” from the then-current ratio of 1.24 to a new ratio of 1.39; and
 
    Extend the term of the 1996 Plan by six years until December 31, 2019.
     Additionally, on April 21, 2010, our Board of Directors (“Board”) approved an amendment to the 1996 Plan providing that (a) time-based awards, other than options or SARS, shall vest in full no earlier than three (3) years from the date of grant and (b) performance-based awards, other than options or SARS, shall vest in full no earlier than one year from the date of the grant. Notwithstanding the above, the Board may grant awards that do not conform to such vesting requirements, so long as the aggregate number of shares of common stock subject to all such non-conforming awards outstanding at any time does not exceed ten percent (10%) of the shares of common stock then subject to the 1996 Plan.
     The 1996 Plan, as amended and restated, is attached as Exhibit 10.1 to this Quarterly Report.
