Gartner delivers its principal products and services globally through four business segments: Research, Events, Consulting and Talent Assessment & Other.

When used in these notes, the terms “Gartner,” “Company,” “we,” “us,” or “our” refer to Gartner, Inc. and its consolidated subsidiaries. Basis of presentation . The accompanying interim condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”), as defined in the Financial Accounting Standards Board ("FASB") Accounting Standards Codification (“ASC”) Topic 270 for interim financial information and with the applicable instructions of the U.S. Securities and Exchange Commission (“SEC”) Rule 10-01 of Regulation S-X on Form 10-Q and should be read in conjunction with the consolidated financial statements and related notes of the Company filed in its Annual Report on Form 10-K for the year ended December 31, 2017 . The fiscal year of Gartner is the twelve-month period from January 1 through December 31. In the opinion of management, all normal recurring accruals and adjustments considered necessary for a fair presentation of financial position, results of operations and cash flows at the dates and for the periods presented herein have been included. The results of operations for the three months ended March 31, 2018 may not be indicative of the results of operations for the remainder of 2018 or beyond. Principles of consolidation . The accompanying interim condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated. Use of estimates . The preparation of the accompanying interim condensed consolidated financial statements requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Such estimates include the valuation of fees receivable, goodwill, intangible assets, and other long-lived assets, as well as tax accruals and other liabilities. In addition, estimates are used in revenue recognition, income tax expense or benefit, performance-based compensation charges, depreciation and amortization. Management believes its use of estimates in these interim condensed consolidated financial statements to be reasonable. Management continually evaluates and revises its estimates using historical experience and other factors, including the general economic environment and actions it may take in the future. Management adjusts these estimates when facts and circumstances dictate. However, these estimates may involve significant uncertainties and judgments and cannot be determined with precision. In addition, these estimates are based on management’s best judgment at a point in time. As a result, differences between our estimates and actual results could be material and would be reflected in the Company’s consolidated financial statements in future periods. Adoption of new accounting standards. The Company adopted the accounting standards described below during the three months ended March 31, 2018: Stock Compensation Award Modifications — On January 1, 2018, the Company adopted ASU No. 2017-09, " Compensation—Stock Compensation - Scope of Modification Accounting " ("ASU No. 2017-09"). ASU No. 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The adoption of ASU No. 2017-09 had no impact on the Company's consolidated financial statements. Retirement Benefits Cost Presentation — On January 1, 2018, the Company adopted ASU No. 2017-07, "Compensation—Retirement Benefits" ("ASU No. 2017-07"). ASU No. 2017-07 improves the reporting of net benefit cost in the financial statements, and provides additional guidance on the presentation of net benefit cost in the income statement and clarifies the components eligible for capitalization. The adoption of ASU No. 2017-07 had an immaterial impact on the classification of benefit expense on the Company's Condensed Consolidated Statements of Operations. Partial Sales of Non-financial Asset s — On January 1, 2018, the Company adopted ASU No. 2017-05, "Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Non-financial Assets" ("ASU No. 2017-05"). ASU No. 2017-05 clarifies the scope of the FASB’s recently established guidance on non-financial asset de-recognition as well as the accounting for partial sales of non-financial assets. It conforms the de-recognition guidance on non-financial assets with the model for revenue transactions. The adoption of ASU No. 2017-05 had no impact on the Company's consolidated financial statements. Definition of a Business — On January 1, 2018, the Company adopted ASU No. 2017-01, "Clarifying the Definition of a Business" ("ASU No. 2017-01"). ASU No. 2017-01 changes the U.S. GAAP definition of a business. Such change can impact the accounting for asset purchases, acquisitions, goodwill impairment and other assessments. The adoption of ASU No. 2017-01 had no impact on the Company's consolidated financial statements. Presentation of Restricted Cash — On January 1, 2018, the Company adopted ASU No. 2016-18, "Restricted Cash" ("ASU No. 2016-18"). ASU No. 2016-18 requires that amounts generally described as restricted cash and restricted cash equivalents be presented with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts presented on an entity's statement of cash flows. ASU No. 2016-18 must be applied using a retrospective transition method to each comparative period presented in an entity's financial statements. As a result of the adoption of ASU No. 2016-18, the Company's restricted cash balances are now included in the beginning-of-period and end-of-period total amounts presented on the accompanying Condensed Consolidated Statements of Cash Flows. When compared to the Company's previously issued statement of cash flows for the three months ended March 31, 2017, the adoption of ASU No. 2016-18 resulted in: (i) a reduction of $18.2 million in cash used in investing activities; (ii) an increase of $43.3 million in the end-of-period total cash amount; and (iii) an increase of $25.1 million in the beginning-of-period total cash amount. Below is a table reconciling the beginning-of-period and end-of-period total cash amounts included in the Condensed Consolidated Balance Sheets to the amounts presented in the Condensed Consolidated Cash Flow Statements (in thousands). March 31, December 31, 2018 2017 2017 2016 Cash and cash equivalents $ 189,979 $ 1,227,891 $ 538,908 $ 474,233 Restricted cash classified in (1), (2): Prepaid expenses and other current assets 18,143 25,121 15,148 25,121 Other assets — 18,150 3,002 — Cash classified as held-for-sale (3) 19,508 — 10,000 — Cash and cash equivalents and restricted cash per the Condensed Consolidated Statements of Cash Flows $ 227,630 $ 1,271,162 $ 567,058 $ 499,354 (1) Restricted cash pertains to escrow accounts established in connection with certain of the Company's business acquisitions. Generally, such cash is restricted to use due to provisions contained in the underlying asset purchase agreement. The Company will disburse the restricted cash to the sellers of the businesses upon satisfaction of any contingencies described in such agreements (e.g., potential indemnification claims, etc.). (2) Restricted cash is recorded in Prepaid expenses and other current assets and Other assets in the Company's consolidated balance sheets with the short-term or long-term classification dependent on the projected timing of disbursements to the sellers. (3) Represents cash classified as a held-for-sale asset for certain businesses that were acquired as part of the CEB acquisition. See Note 2 — Acquisitions and Divestitures for additional information. Income Taxes — On January 1, 2018, the Company adopted ASU No. 2016-16, "Intra-Entity Transfers of Assets Other Than Inventory" ("ASU No. 2016-16"). ASU No. 2016-16 accelerates the recognition of taxes on certain intra-entity transactions. U.S. GAAP previously required deferral of the income tax implications of an intercompany sale of assets until the assets were sold to a third party or recovered through use. Under ASU No. 2016-16, the seller’s tax effects and the buyer’s deferred taxes on asset transfers are immediately recognized upon the sale. Pursuant to the transition rules in ASU No. 2016-16, any taxes attributable to pre-2018 intra-entity transfers that were previously deferred should be accelerated and recorded to accumulated earnings on the date of adoption. As a result of this transition rule, certain of the Company's balance sheet income tax accounts pertaining to pre-2018 intra-entity transfers, which aggregated $13.7 million , were reversed against accumulated earnings on January 1, 2018. ASU No. 2016-16 could have a material post-adoption impact on the Company's consolidated financial statements, depending on the nature, size and tax consequences of future intra-entity transfers, if any. However, ASU 2016-16 had no impact on the Company's operating results during the three months ended March 31, 2018. Statement of Cash Flows — On January 1, 2018, the Company adopted ASU No. 2016-15, "Classification of Certain Cash Receipts and Cash Payments" ("ASU No. 2016-15"). ASU No. 2016-15 sets forth classification requirements for certain cash flow transactions. The adoption of ASU No. 2016-15 had no impact on the Company's consolidated financial statements. Financial Instruments Recognition and Measurement — On January 1, 2018, the Company adopted ASU No. 2016-01, " Financial Instruments Overall - Recognition and Measurement of Financial Assets and Liabilities " ("ASU No. 2016-01") to address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. Among the significant changes required by ASU No. 2016-01 is that equity investments are to be measured at fair value with changes in fair value recognized in net income. The adoption of ASU No. 2016-01 had no impact on the Company's consolidated financial statements. Revenue Recognition — On January 1, 2018, the Company adopted ASU No. 2014-09, " Revenue from Contracts with Customers " ("ASU No. 2014-09"). The adoption of the standard did not have a material impact on the Company's accounting policies or consolidated financial statements. However, as required by ASU No. 2014-09, the Company's disclosures around revenue recognition have been significantly expanded. The following sections provide an overview of the Company's revenues by segment along with the required disclosures under the new standard: Our business and our revenues Gartner delivers its principal products and services globally through four business segments: Research, Events, Consulting and Talent Assessment & Other. Our revenues by business segment are discussed below: Research Research provides trusted, objective insights and advice on the mission-critical priorities of leaders across all functional areas of an enterprise through research and other reports, briefings, proprietary tools, access to our analysts, peer networking services and membership programs that enable our clients to make better decisions. Gartner's traditional strengths in information technology (“IT”), marketing and supply chain research were enhanced in 2017 with Gartner's acquisition of CEB Inc. ("CEB"), which added CEB's best practice and talent management research insights across a range of business functions, to include human resources, finance, sales and legal. Research revenues are mainly derived from subscription contracts for research products, representing approximately 90% of the segment’s revenue. The related revenues are deferred and recognized ratably over the applicable contract term (i.e., as we provide the service over the contract period). Fees derived from assisting organizations in selecting the right business software for their needs are recognized at a point in time (i.e., when the lead is provided to the vendor). The Company enters into subscription contracts for research products that generally are for twelve-month periods or longer. Approximately 65% of our annual and multi-year Research subscription contracts provide for billing of the first annual period upon signing. In subsequent years, multi-year subscription contracts are normally billed prior to the contract’s anniversary date. Our other Research subscription contracts are usually invoiced in advance, commencing with the contract signing, on (i) a quarterly, monthly or other recurring basis or (ii) in accordance with a customized invoicing schedule. Research contracts are generally non-cancelable and non-refundable, except for government contracts that may have cancellation or fiscal funding clauses, which historically have not produced material cancellations. It is our policy to record the amount of a subscription contract that is billable as a fee receivable at the time the contract is signed with a corresponding amount as deferred revenue because the contract represents a legally enforceable claim. Events Events provides business professionals across an organization with the opportunity to learn, share and network. From our flagship Chief Information Officer event, Gartner Symposium/ITxpo, to industry-leading conferences focused on specific business roles and topics, to member-driven sessions, our events enable attendees to experience the best of Gartner insight and advice live. We earn revenues from both the attendees and exhibitors at our events. Attendees are generally invoiced for the full attendance fee upon their completion of an online registration form or their signing of a contract, while exhibitors typically make several individual payments commencing with the signing of a contract. We collect almost all of the invoiced amounts in advance of the related event, resulting in the recording of deferred revenue. We recognize both the attendee and exhibitor revenue as we satisfy our related performance obligations (i.e., when the related symposium, conference, summit or exhibition is held). The Company defers certain costs directly related to its events and expenses those costs in the period during which the related symposium, conference or exhibition occurs. The Company's policy is to defer only those costs, primarily prepaid site and production services costs, which are incremental and are directly attributable to a specific event. Other costs of organizing and producing our events, primarily Company personnel and non-event specific expenses, are expensed in the period incurred. At the end of each fiscal quarter, the Company assesses, on an event-by-event basis, whether the expected direct costs of producing a scheduled event will exceed the expected revenues. If such costs are expected to exceed revenues, the Company records the expected loss in the period determined. Consulting Consulting provides customized solutions to unique client needs through on-site, day-to-day support, as well as proprietary tools for measuring and improving IT performance with a focus on cost, performance, efficiency and quality, and contract optimization services. Consulting revenues, primarily derived from custom consulting and measurement services, are principally generated from fixed fee or time and materials engagements. Revenues from fixed fee engagements are recognized on a proportional performance basis, while revenues from time and material engagements are recognized as work is delivered and/or services are provided. In both of these circumstances, we satisfy our performance obligations and control of the services are passed to our customers over time (i.e., during the duration of the contract or consulting engagement). On a contract-by-contract basis, we typically use actual labor hours incurred compared to total expected labor hours to measure the Company’s proportional performance in respect of our fixed fee engagements. If our labor and other costs on an individual contract are expected to exceed the total contract value or the contract’s funded ceiling amount, the Company reflects an adjustment to the contract’s overall profitability in the period determined. Revenues related to contract optimization engagements are contingent in nature and are only recognized at a point in time when all of the conditions related to their payment have been satisfied. Consulting customers are invoiced based on the specific terms and conditions in their underlying contracts. We typically invoice our Consulting customers after we have satisfied some or all of the related performance obligation and the related revenue has been recognized. We record fees receivable for amounts that are billed or billable. We also record contract assets, which represent amounts for which we have recognized revenue but lack the unconditional right to payment as of the balance sheet date due to our required continued performance under the relevant contract, progress billing milestones, or other billing-related restrictions. The Company’s contract assets are discussed below. Talent Assessment & Other The Talent Assessment & Other segment helps organizations assess, engage, manage and improve talent. These services are provided through knowledge and skills assessments, training programs, workshops, and survey and questionnaire services. Talent Assessment & Other segment revenues arising from knowledge and skills assessment services are recognized based on the nature of the underlying contract: (i) ratably over the term of the service period; (ii) upon delivery; or (iii) on a proportional performance basis. Revenues from training programs, workshops, and survey and questionnaire products are primarily recognized upon delivery of the service. In April 2018, the Company sold its CEB Talent Assessment and CEB Workforce Survey and Analytics businesses, which were reported in the Talent Assessment & Other segment. Note 2 - Acquisitions and Divestitures provides additional information regarding these divestitures. Overview of ASU No. 2014-09 ASU No. 2014-09 requires a five-step evaluative process that consists of: (1) Identifying the contract with the customer; (2) Identifying the performance obligations in the contract; (3) Determining the transaction price for the contract; (4) Allocating the transaction price to the performance obligations in the contract; and (5) Recognizing revenue when (or as) performance obligations are satisfied. ASU No. 2014-09 is intended to clarify the principles for recognizing revenue by removing inconsistencies and weaknesses in existing revenue recognition rules; provide a more robust framework for addressing revenue recognition issues; improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and provide more useful information to users of financial statements through improved disclosures. The Company adopted ASU No. 2014-09 using the modified retrospective method of adoption. Under this method of adoption, the cumulative effect of applying the new standard is recorded at the date of initial application, with no restatement of the comparative prior periods presented. The adoption of ASU No. 2014-09 did not result in a cumulative effect adjustment to the Company's Accumulated earnings in its consolidated financial statements. However, the adoption of the new standard required reclassifications of certain amounts presented in the Company’s consolidated balance sheet. As of January 1, 2018, these items were (i) the reclassification of certain fees receivable that met the definition of a contract asset, aggregating $26.7 million , from Fees receivable, net to Prepaid expenses and other current assets; and (ii) the reclassification of a refund liability, aggregating $6.2 million , from the allowance for fees receivable to Accounts payable and accrued liabilities. Related to our adoption of ASU No. 2014-09, we elected to (i) apply the provisions of this new accounting guidance only to contracts that were not completed at the date of initial application and (ii) utilize a practical expedient whereby we reflected the aggregate effect of all contract modifications that occurred prior to January 1, 2018 (rather than retrospectively restating the affected contracts) when identifying our satisfied and unsatisfied performance obligations, determining the transaction prices with our customers, and allocating such transaction prices to our satisfied and unsatisfied performance obligations. These two elections had no financial impact. Prior to January 1, 2018, the Company recognized revenue in accordance with then-existing U.S. GAAP and SEC Staff Accounting Bulletin No. 104, "Revenue Recognition" (“prior GAAP”). Under both ASU No. 2014-09 and prior GAAP, revenue can only be recognized when all of the required criteria are met. Although there were some minor changes to the Company’s revenue recognition policies and procedures effective January 1, 2018 with the adoption of ASU No. 2014-09, there were no material differences between the timing and amount of revenues recognized under ASU No. 2014-09 and prior GAAP. The accompanying Condensed Consolidated Statements of Operations present revenues net of any sales or value-added taxes that we collect from customers and remit to government authorities. ASU No. 2014-09 requires that we assess at inception all of the promises in a customer contract to determine if a promise is a separate performance obligation. To identify our performance obligations, we consider all of the services promised in a customer contract, regardless of whether they are explicitly stated or are implied by customary business practices. If we conclude that a service is separately identifiable and distinct from the other offerings in a contract, we account for such a promise as a separate performance obligation. If a customer contract has more than one performance obligation, then the total contract consideration is allocated among the separate deliverables based on their stand-alone selling prices, which are determined based on the prices at which the Company discretely sells the stand-alone services. If a contract includes a discount or other pricing concession, the transaction price is allocated among the performance obligations on a proportionate basis using the relative stand-alone selling prices of the individual deliverables being transferred to the customer, unless the discount or other pricing concession can be ascribed to specifically identifiable performance obligations. The contracts with our customers delineate the final terms and conditions of the underlying arrangement, including product descriptions, subscription periods, deliverables, quantity and price of each service purchased. Since the transaction price of almost all of our customer contracts is typically agreed upon upfront and generally does not fluctuate during the duration of the contract, variable consideration is insignificant. The Company may engage in certain financing transactions with customers but these arrangements have been limited in number and not material. Required Disclosures under ASU No. 2014-09 ASU No. 2014-09 requires significantly expanded disclosures around the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. These additional disclosures are provided below: Disaggregated Revenues We believe that disaggregating the Company’s revenues by primary geographic location and the timing of when revenue is recognized achieves the disclosure objectives in ASU No. 2014-09. Our disaggregated revenue information by reportable segment is presented for the periods indicated in the tables below (in thousands). Three Months Ended March 31, 2018 Research Events Consulting Talent Assessment & Other Total Primary Geographic Markets: (1) United States and Canada $ 489,713 $ 24,069 $ 45,129 $ 34,594 $ 593,505 Europe, Middle East and Africa 184,547 16,891 29,938 28,290 259,666 Other International 89,664 5,127 7,829 7,774 110,394 Total revenues $ 763,924 $ 46,087 $ 82,896 $ 70,658 $ 963,565 Three Months Ended March 31, 2017 Research Events Consulting Talent Assessment & Other Total Primary Geographic Markets: (1) United States and Canada $ 327,492 $ 17,663 $ 47,832 $ — $ 392,987 Europe, Middle East and Africa 115,802 14,095 23,823 — 153,720 Other International 68,012 3,511 6,939 — 78,462 Total revenues $ 511,306 $ 35,269 $ 78,594 $ — $ 625,169 (1) Revenues are reported based on where the sale is fulfilled. Three Months Ended March 31, 2018 Research Events Consulting Talent Assessment & Other Total Timing of Revenue Recognition: Transferred over time (1) $ 701,096 $ — $ 74,010 $ 58,946 $ 834,052 Transferred at a point in time (2) 62,828 46,087 8,886 11,712 129,513 Total revenues $ 763,924 $ 46,087 $ 82,896 $ 70,658 $ 963,565 Three Months Ended March 31, 2017 Research Events Consulting Talent Assessment & Other Total Timing of Revenue Recognition: Transferred over time (1) $ 466,706 $ — $ 64,994 $ — $ 531,700 Transferred at a point in time (2) 44,600 35,269 13,600 — 93,469 Total revenues $ 511,306 $ 35,269 $ 78,594 $ — $ 625,169 (1) These Research revenues were recognized in connection with performance obligations that were satisfied over time using a time-elapsed output method to measure progress. The corresponding Consulting revenues were recognized over time using labor hours as an input measurement basis. Talent Assessment & Other revenues in this category were recognized using either a time-elapsed output method, performance-based milestone approach or labor hours, depending on the nature of the underlying customer contract. (2) The revenues in this category were recognized in connection with performance obligations that were satisfied at the point in time the contractual deliverables were provided to the customer. Determining a measure of progress for performance obligations that are satisfied over time and when control transfers for performance obligations that are satisfied at a point in time requires us to make judgments that affect the timing of when revenue is recognized. A key factor in this determination is when the customer is able to direct the use of, and can obtain substantially all of the benefits from, the deliverable. For performance obligations recognized in accordance with a time-elapsed output method, the Company’s efforts are expended consistently throughout the contractual period and the Company transfers control evenly by providing stand-ready services. For performance obligations satisfied under our Consulting fixed fee and time and materials engagements, we believe that labor hours are the best measure of depicting the Company’s progress because labor output corresponds directly to the value of the Company’s performance to date as control is transferred. In our Talent Assessment & Other segment, we select a method to assess the completion of our performance obligations that best aligns with the specific characteristics of the individual customer contract. We believe that these methods to measure progress provide a reasonable and supportable determination as to when we transfer control over these services to our customers. For customer contracts that are greater than one year in duration, the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied (or partially unsatisfied) as of March 31, 2018 was approximately $2.1 billion . The Company expects to recognize $1,060.6 million , $856.7 million and $209.8 million of this revenue (most of which pertains to Research) during the remainder of 2018, the year ending December 31, 2019 and thereafter, respectively. The Company applies the practical expedient allowed in ASU No. 2014-09 and, accordingly, it does not disclose such performance obligation information for customer contracts that have original durations of one year or less. Customer Contract Assets and Liabilities The timing of the recognition of revenues, the amount and timing of our billings and cash collections, as well as upfront customer payments, result in the recording of both assets and liabilities on our Condensed Consolidated Balance Sheets. The payment terms and conditions in our customer contracts vary. In some cases, customers prepay and, in other cases, after we conduct a credit evaluation, payment may be due in arrears. Because the timing of the delivery of our services typically differs from the timing of customer payments, the Company recognizes either a contract asset (we perform either fully or partially under the contract but a contingency remains) or a contract liability (upfront customer payments precede our performance, resulting in deferred revenue). Amounts recorded as contract assets are reclassified to fees receivable when all of the outstanding conditions have been resolved and our right to payment becomes unconditional. Contracts with payments due in arrears are also recognized as fees receivable. As our contractual performance obligations are satisfied over time or at a point in time, the Company correspondingly relieves its contract liabilities and records the associated revenue. The table below provides information regarding certain of the Company’s balance sheet accounts that pertain to its contracts with customers, to exclude our held-for-sale businesses (in thousands): March 31, December 31, 2018 2017 Assets: Fees receivable, gross (1) $ 1,142,064 $ 1,162,871 Contract assets (2) $ 27,593 $ 26,672 Contract liabilities: Deferred revenues (current liability) (3) $ 1,719,637 $ 1,630,198 Non-current deferred revenues (3) 16,139 16,205 Total contract liabilities $ 1,735,776 $ 1,646,403 (1) Fees receivable represent the unconditional right of payment from our customers and includes both billed and unbilled amounts. (2) Contract assets represent recognized revenue for which we do not have an unconditional right to payment as of the balance sheet date because the project may be subject to a progress milestone or some other billing restriction. In the accompanying Condensed Consolidated Balance Sheets, contract assets are recorded in Prepaid expenses and other current assets as of March 31, 2018 and Fees receivable, net as of December 31, 2017. (3) Deferred revenues represent amounts (i) for which the Company has received an upfront customer payment or (ii) that pertain to recognized fees receivable. Both situations occur before the completion of our performance obligation(s). During the three months ended March 31, 2018, the Company recognized $605.5 million of revenue that was attributable to deferred revenues that were recorded at December 31, 2017. Such amount primarily consisted of (i) Research and Talent Assessment & Other revenue that was recognized ratably as control of the goods or services passed to the customer and (ii) Events revenue pertaining to symposia, conferences, summits or exhibitions that occurred during the calendar quarter. During the three months ended March 31, 2018, the Company recorded no material impairments related to its contract assets. The Company does not in the normal course of business recognize revenues from performance obligations satisfied in prior periods. Allowance for Losses and Revenue Reserves As of December 31, 2017, the Company maintained an allowance for losses that included a bad debt allowance and a revenue reserve.
