Segments. Gartner delivers its products and services globally through three business segments: Research, Conferences and Consulting. Note 9 — Revenue and Related Matters and Note 16 — Segment Information describe the products and services offered by each of our segments and provide additional financial information for those segments.

During 2018, the Company divested all of the non-core businesses that comprised its Other segment and moved a small residual product from the Other segment into the Research business and, as a result, no operating activity has been recorded in the Other segment in 2019 or 2020. Note 2 — Acquisitions and Divestitures provides additional information regarding the Company’s 2018 divestitures.

Basis of presentation. The accompanying 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”), for financial information and with the applicable instructions of U.S. Securities and Exchange Commission (“SEC”) Regulation S-X.

The fiscal year of Gartner is the twelve-month period from January 1 through December 31. All references to 2020, 2019 and 2018 herein refer to the fiscal year unless otherwise indicated. When used in these notes, the terms “Gartner,” the “Company,” “we,” “us” or “our” refer to Gartner, Inc. and its consolidated subsidiaries.

Use of estimates. The preparation of the accompanying 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 the accompanying 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.

In December 2019, a novel coronavirus disease (“COVID-19”) was reported in Wuhan, China and on March 11, 2020, the World Health Organization characterized COVID-19 as a pandemic. Any future asset impairment charges, increase in allowance for doubtful accounts, or restructuring charges could be more likely if the negative effects of the COVID-19 pandemic continue and will be dependent on the severity and duration of this crisis. To date, the Company has not observed any material impairments of its assets or a significant change in the fair value of assets due to the COVID-19 pandemic.

Business acquisitions. The Company accounts for business acquisitions in accordance with the acquisition method of accounting as prescribed by FASB ASC Topic 805, Business Combinations. The acquisition method of accounting requires the Company to record the assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date, with certain exceptions. Any excess of the consideration transferred over the estimated fair value of the net assets acquired, including identifiable intangible assets, is recorded as goodwill. Under the acquisition method, the operating results of acquired

The determination of the fair values of intangible and other assets acquired in an acquisition requires management judgment and the consideration of a number of factors, including the historical financial performance of acquired businesses and their projected future performance, and estimates surrounding customer turnover, as well as assumptions regarding the level of competition and the costs necessary to reproduce certain assets. Establishing the useful lives of intangible assets also requires management judgment and the evaluation of a number of factors, including the expected use of an asset, historical client retention rates, consumer awareness and trade name history, as well as any contractual provisions that could limit or extend an asset’s useful life.

•Research revenues are mainly derived from subscription contracts for research products. The related revenues are deferred and recognized ratably over the applicable contract term. Fees derived from assisting organizations in selecting the right business software for their needs are recognized when the leads are provided to vendors.

•Consulting revenues are principally generated from fixed fee and time and materials engagements. Revenues from fixed fee contracts are recognized as the Company works to satisfy our performance obligations. Revenues from time and materials engagements are recognized as work is delivered and/or services are provided. Revenues related to contract optimization engagements are contingent in nature and are only recognized upon satisfaction of all conditions related to their payment.

The majority of the Company’s Research contracts are billable upon signing, absent special terms granted on a limited basis from time to time. Research contracts are generally non-cancelable and non-refundable, except for government contracts that may have cancellation or fiscal funding clauses. It is the Company’s 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.

Allowance for losses. On January 1, 2020 , the Company adopted ASU No. 2016-13, Financial Instruments—Credit Losses. Prior to January 1, 2020, the Company recognized the allowance for losses on bad debts in accordance with then-existing U.S. GAAP under FASB ASC Topic 310, Receivables. Information regarding the Company’s accounting for credit losses, including our adoption of the new accounting standard, is provided below under the heading “Adoption of new accounting standards”.

Commission expense. The Company records deferred commissions upon signing a customer contract and amortizes the deferred amount over a period that aligns with the transfer to the customer of the services to which the commissions relate. Note 9 — Revenue and Related Matters provides additional information regarding deferred commissions and the amortization of such costs.

Stock-based compensation expense. The Company accounts for stock-based compensation awards in accordance with FASB ASC Topics 505 and 718 and SEC Staff Accounting Bulletins No. 107 and No. 110. Stock-based compensation expense for equity awards is based on the fair value of the award on the date of grant. The Company recognizes stock-based compensation expense over the period that the related service is performed, which is generally the same as the vesting period of the underlying award. Forfeitures are recognized as they occur. A change in any of the terms or conditions of stock-based

compensation awards is accounted for as a modification of the award. Incremental compensation cost is measured as the excess, if any, of the fair value of the modified award over the fair value of the original award immediately before its terms are modified, measured based on the fair value of the awards at the modification date. For vested awards, the Company recognizes incremental compensation cost in the period the modification occurs. For unvested awards, the Company recognizes any incremental compensation expense at the modification date or ratably over the requisite remaining service period, as appropriate. If the fair value of the modified award is lower than the fair value of the original award immediately before modification, the minimum compensation cost the Company recognizes is the cost of the original award. Note 10 — Stock-Based Compensation provides additional information regarding the Company’s stock-based compensation activity.

Income taxes. The Company uses the asset and liability method of accounting for income taxes. We estimate our income taxes in each of the jurisdictions where we operate. This process involves estimating our current tax expense or benefit together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in our consolidated balance sheets. When assessing the realizability of deferred tax assets, we consider if it is more likely than not that some or all of the deferred tax assets will not be realized. In making this assessment, we consider the availability of loss carryforwards, projected reversals of deferred tax liabilities, projected future taxable income, and ongoing prudent and feasible tax planning strategies. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained based on the technical merits of the position. Recognized tax positions are measured at the largest amount of benefit with greater than a 50% likelihood of being realized. The Company uses estimates in determining the amount of unrecognized tax benefits associated with uncertain tax positions. Significant judgment is required in evaluating tax law and measuring the benefits likely to be realized. Uncertain tax positions are periodically re-evaluated and adjusted as more information about their ultimate realization becomes available. Note 12 — Income Taxes provides additional information regarding the Company’s income taxes.

On April 1, 2018, the Company early adopted ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU No. 2018-02”). ASU No. 2018-02 provides an entity with the option to reclassify to retained earnings the tax effects from items that have been stranded in accumulated other comprehensive income as a result of the U.S. Tax Cuts and Jobs Act of 2017 (the “Act”). Gartner elected to early adopt ASU No. 2018-02 as of the beginning of the second quarter of 2018, which resulted in a reclassification of $0.6 million of stranded tax amounts related to the Act from Accumulated other comprehensive (loss) income, net to Accumulated earnings. ASU No. 2018-02 had no impact on the Company’s operating results in 2020, 2019 or 2018.

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, a seller’s tax effects and a buyer’s deferred taxes on asset transfers are immediately recognized upon a 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, 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. Additionally, in accordance with the new requirements of ASU No. 2016-16, the Company recorded income tax benefits of approximately (i) $28.3 million and $38.1 million in 2020 and 2019, respectively, from intercompany sales of certain intellectual property and (ii) $6.8 million in 2018 related to intra-entity transfers upon the merger of certain foreign subsidiaries. In the future, there could be a material impact from ASU No. 2016-16, depending on the nature, size and tax consequences of intra-entity transfers, if any.

Cash and cash equivalents and restricted cash. Cash and cash equivalents includes cash and all highly liquid investments with original maturities of three months or less, which are considered to be cash equivalents. The carrying value of cash equivalents approximates fair value due to the short-term maturity of such instruments. Investments with maturities of more than three months are classified as marketable securities. Interest earned is recorded in Interest income in the Consolidated Statements of Operations.

U.S. GAAP 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. Below is a table presenting the beginning-of-period and end-of-period cash amounts from the


	December 31,
	2020		2019		2018		2017
Cash and cash equivalents	$	712,583	$	280,836	$	156,368	$	538,908
Restricted cash classified in (1), (2):
Prepaid expenses and other current assets	—		—		2,295		15,148
Other assets	—		—		—		3,002
Cash classified as held-for-sale (3)	—		—		—		10,000
Cash and cash equivalents and restricted cash per the Consolidated Statements of Cash Flows	$	712,583	$	280,836	$	158,663	$	567,058

(1)Restricted cash consists of 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 stock or 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.).

Leases. On January 1, 2019, the Company adopted ASC 842, Leases using a modified retrospective approach. ASC 842 significantly changed the accounting for leases because a right-of-use model is now used whereby a lessee must record a right-of-use asset and a related lease liability on its balance sheet for most of its leases. Under ASC 842, leases are classified as either operating or finance arrangements, with such classification affecting the pattern of expense recognition in an entity’s income statement. For operating leases, ASC 842 requires recognition in an entity’s income statement of a single lease cost, calculated so that the cost of the lease is allocated over the lease term, generally on a straight-line basis.

Prior to January 1, 2019, the Company recognized lease expense in accordance with then-existing U.S. GAAP under FASB ASC Topic 840, Leases (“ASC Topic 840”). Although there were significant changes to the Company’s leasing policies and procedures effective January 1, 2019 with the adoption of ASC 842, the lease expense recognition patterns under ASC Topic 842 in 2020 and 2019 and ASC Topic 840 in 2018 were substantively the same. As required by the new lease standard, the Company’s disclosures regarding its leasing activities have been significantly expanded to enable users of our Consolidated Financial Statements to assess the amount, timing and uncertainty of cash flows related to leases. Information regarding our adoption of ASC 842 and its impact on the Company’s Consolidated Financial Statements and related disclosures is provided at Note 7 — Leases.

Property, equipment and leasehold improvements. Equipment, leasehold improvements and other fixed assets owned by the Company are recorded at cost less accumulated depreciation and amortization. Fixed assets, other than leasehold improvements, are depreciated using the straight-line method over the estimated useful life of the underlying asset. Leasehold improvements are amortized using the straight-line method over the shorter of the estimated useful life of the improvement or the remaining term of the related lease. Depreciation and amortization expense for fixed assets was $93.9 million, $82.1 million and $68.6 million in 2020, 2019 and 2018, respectively. Property, equipment and leasehold improvements, net are presented in the table below (in thousands).


	Useful Life	December 31,
Category	(Years)	2020		2019
Computer equipment and software	2-7	$	277,973	$	256,451
Furniture and equipment	3-8	114,622		104,370
Leasehold improvements	2-15	283,773		275,114
Total cost		676,368		635,935
Less — accumulated depreciation and amortization		(339,603)		(291,356)
Property, equipment and leasehold improvements, net		$	336,765	$	344,579

The Company incurs costs to develop internal-use software used in its operations. Certain of those costs that meet the criteria in FASB ASC Topic 350, Intangibles - Goodwill and Other are capitalized and amortized over future periods. Net capitalized internal-use software development costs were $58.2 million and $55.7 million at December 31, 2020 and 2019, respectively, and are included in Computer equipment and software in the table above. Amortization expense for capitalized internal-use software development costs, which is included with Depreciation in the Consolidated Statements of Operations, totaled $28.9 million, $20.0 million and $13.2 million in 2020, 2019 and 2018, respectively.

Goodwill. Goodwill represents the excess of the purchase price of acquired businesses over the estimated fair values of the tangible and identifiable intangible net assets acquired. Evaluations of the recoverability of goodwill are performed in accordance with FASB ASC Topic 350, which requires an annual assessment of potential goodwill impairment at the reporting unit level and whenever events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable.

When performing our annual assessment of the recoverability of goodwill, we initially perform a qualitative analysis evaluating whether any events or circumstances occurred or exist that provide evidence that it is more likely than not that the fair value of any of our reporting units is less than the related carrying amount. If we do not believe that it is more likely than not that the fair value of any of our reporting units is less than the related carrying amount, then no quantitative impairment test is performed. However, if the results of our qualitative assessment indicate that it is more likely than not that the fair value of a reporting unit is less than its respective carrying amount, then we perform a two-step quantitative impairment test. Evaluating the recoverability of goodwill requires judgments and assumptions regarding future trends and events. As a result, both the precision and reliability of our estimates are subject to uncertainty.

Our most recent annual impairment test of goodwill was a qualitative analysis conducted during the quarter ended September 30, 2020 that indicated no impairment. Subsequent to completing our 2020 annual impairment test, no events or changes in circumstances were noted that required an interim goodwill impairment test. Note 3 — Goodwill and Intangible Assets provides additional information regarding the Company’s goodwill.

Impairment of long-lived assets. The Company’s long-lived assets primarily consist of intangible assets other than goodwill and property, equipment and leasehold improvements. The Company reviews its long-lived asset groups for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or an asset group may not be recoverable. Such evaluation may be based on a number of factors, including current and projected operating results and cash flows, and changes in management’s strategic direction as well as external economic and market factors. The Company evaluates the recoverability of assets and asset groups by determining whether their carrying values can be recovered through undiscounted future operating cash flows. If events or circumstances indicate that the carrying values might not be recoverable based on undiscounted future operating cash flows, an impairment loss may be recognized. The amount of impairment is measured based on the difference between the projected discounted future operating cash flows, using a discount rate reflecting the Company’s average cost of funds, and the carrying value of the asset or asset group. The Company did not record any impairment charges for long-lived assets or asset groups during the three-year period ended December 31, 2020.

Pension obligations. The Company has defined benefit pension plans at several of its international locations. Benefits earned and paid under those plans are generally based on years of service and level of employee compensation. The Company’s defined benefit pension plans are accounted for in accordance with FASB ASC Topics 715 and 960. The Company determines the periodic pension expense and related liabilities for its defined benefit pension plans through actuarial assumptions and valuations. The service cost component of pension expense is recorded as SG&A expense and all other components of pension expense are recorded as Other (expense) income, net in the Consolidated Statements of Operations. Note 15 — Employee Benefits provides additional information regarding the Company’s defined benefit pension plans.

Foreign currency exposure. The functional currency of our foreign subsidiaries is typically the local currency. All assets and liabilities of foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Income and expense items are translated at average exchange rates for the year. The resulting translation adjustments are recorded as foreign

Currency transaction gains or losses arising from transactions denominated in currencies other than the functional currency of a subsidiary are recognized in results of operations as part of Other (expense) income, net in the Consolidated Statements of Operations. The Company had net currency transaction gains (losses) of $12.5 million, $(1.1) million and $9.2 million in 2020, 2019 and 2018, respectively. The Company enters into foreign currency forward exchange contracts to mitigate the effects of adverse fluctuations in foreign currency exchange rates on certain transactions. Those contracts generally have short durations and are recorded at fair value with both realized and unrealized gains and losses recorded in Other (expense) income, net. The net loss from foreign currency forward exchange contracts was $14.1 million, $2.5 million and $10.4 million in 2020, 2019 and 2018, respectively. Note 13 — Derivatives and Hedging provides additional information regarding the Company’s foreign currency forward exchange contracts.

Concentrations of credit risk. Assets that may subject the Company to concentration of credit risk consist primarily of short-term, highly liquid investments classified as cash equivalents, fees receivable, contract assets, interest rate swaps and a pension reinsurance asset. The majority of the Company’s cash equivalent investments and its interest rate swap contracts are with investment grade commercial banks. Fees receivable and contract asset balances deemed to be collectible from customers have limited concentration of credit risk due to our diverse customer base and geographic dispersion. The Company’s pension reinsurance asset (see Note 15 — Employee Benefits) is maintained with a large international insurance company that was rated investment grade as of December 31, 2020 and 2019.

Stock repurchase programs. The Company records the cost to repurchase shares of its own common stock as treasury stock. Shares repurchased by the Company are added to treasury shares and are not retired. Note 8 — Stockholders’ Equity provides additional information regarding the Company’s common stock repurchase activity.

Implementation Costs in a Cloud Computing Arrangement — In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU No. 2018-15”). ASU No. 2018-15 aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. Costs that are capitalized under ASU No. 2018-15 will be expensed over the term of the cloud computing arrangement. Gartner adopted ASU No. 2018-15 on January 1, 2020 on a prospective basis. The adoption of ASU No. 2018-15 did not have a material impact on the Company’s Consolidated Financial Statements.

Fair Value Measurement Disclosures — In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU No. 2018-13”). ASU No. 2018-13, which is part of the FASB’s broader disclosure framework project, modified and supplemented the previous U.S. GAAP disclosure requirements pertaining to fair value measurements, with an emphasis on Level 3 disclosures of the valuation hierarchy. Gartner adopted ASU No. 2018-13 on January 1, 2020. The adoption of ASU No. 2018-13 did not have a material impact on the Company’s Consolidated Financial Statements.

Goodwill Impairment — In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other - Simplifying the Test for Goodwill Impairment (“ASU No. 2017-04”). ASU No. 2017-04 simplified the determination of the amount of goodwill to be potentially charged off by eliminating Step 2 of the goodwill impairment test under previous U.S. GAAP. Gartner adopted ASU No. 2017-04 on January 1, 2020. The adoption of ASU No. 2017-04 did not have a material impact on the Company’s Consolidated Financial Statements.

Financial Instrument Credit Losses — In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (“ASU No. 2016-13”). ASU No. 2016-13 amended the previous financial instrument impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables. Gartner adopted ASU No. 2016-13 on January 1, 2020 with no cumulative effect adjustment to the Company’s opening retained earnings. The Company applied the expected credit loss model to its fees receivable balance on January 1, 2020 using a historical loss rate method. The Company’s trade receivables are collected fairly quickly and its credit losses have historically been low. The adoption of ASU No. 2016-13 did not have a material impact on the Company’s Consolidated Financial Statements.

Defined Benefit Plan Disclosures — In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans (“ASU No. 2018-14”). ASU No. 2018-14, which is part of the FASB’s broader disclosure framework project, modified and supplemented the previous U.S. GAAP annual disclosure requirements for employers that sponsor defined benefit pension plans. Gartner adopted ASU No. 2018-14 on December 31, 2020 on a retroactive basis and applied to each comparative period presented in the Company’s Consolidated Financial Statements. The adoption of ASU No. 2018-14 did not have a material impact on the Company’s Consolidated Financial Statements.

Reference Rate Reform — In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform—Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU No. 2020-04”). ASU No. 2020-04 provides that an entity can elect not to apply certain required modification accounting in U.S. GAAP to contracts where all changes to the critical terms relate to reference rate reform (e.g., the expected discontinuance of LIBOR and the transition to an alternative reference interest rate, etc.). In addition, the rule provides optional expedients and exceptions that enable entities to continue to apply hedge accounting for hedging relationships where one or more of the critical terms change due to reference rate reform. The rule became effective for all entities as of March 12, 2020 and will generally no longer be available to apply after December 31, 2022. The Company is currently evaluating the potential impact of ASU No. 2020-04 on its Consolidated Financial Statements, including the rule’s potential impact on any debt modifications or other contractual changes in the future that may result from reference rate reform.

Simplifying the Accounting for Income Taxes — In December 2019, the FASB issued ASU No. 2019-12, Income Taxes—Simplifying the Accounting for Income Taxes (“ASU No. 2019-12”). ASU No. 2019-12 provides new guidance to simplify the accounting for income taxes in certain areas, changes the accounting for select income tax transactions and makes minor ASC improvements. Gartner adopted ASU No. 2019-12 on January 1, 2021. The Company has concluded that ASU No. 2019-12 will not have a material impact on its Consolidated Financial Statements upon adoption.
