Organization and Background	3 Months Ended
Organization and Background	Mar. 31, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Background	Note 1 - Organization and Background Business ZoomInfo Technologies Inc., through its operating subsidiaries provides a go-to-market intelligence platform for sales and marketing teams. The Company’s cloud-based platform provides accurate and comprehensive information on organizations and professionals to help users identify target customers and decision makers, obtain continually updated predictive lead and company scoring, monitor buying signals and other attributes of target companies, craft messages, engage via automated sales tools, and track progress through the deal cycle. Unless otherwise indicated or the context otherwise requires, references to “we,” “us,” “our,” “ZoomInfo,” and the “Company” refer (1) prior to the consummation of the Reorganization Transactions, to ZoomInfo OpCo and its consolidated subsidiaries, and (2) after the consummation of the Reorganization Transactions, to ZoomInfo Technologies Inc. and its consolidated subsidiaries. Organization ZoomInfo Technologies Inc. was formed on November 14, 2019 with no operating assets or operations as a Delaware corporation for the purposes of facilitating an initial public offering (“IPO”) and other related transactions in order to carry on the business of ZoomInfo Holdings LLC (“ZoomInfo OpCo”) (formerly known as DiscoverOrg Holdings, LLC), a Delaware limited liability company. Following consummation of the Reorganization Transactions (as described below), ZoomInfo OpCo became a direct subsidiary of ZoomInfo Intermediate Holdings LLC (“ZoomInfo HoldCo”), a Delaware limited liability company and an indirect subsidiary of ZoomInfo Technologies Inc. The Company headquarters are located in Vancouver, WA, and we operate in eight offices throughout the U.S. and one office in Israel. Initial Public Offering On June 8, 2020, ZoomInfo Technologies Inc. completed the IPO, in which it sold 51,175,000 shares of Class A common stock (including shares issued pursuant to the exercise in full of the underwriters’ option to purchase additional shares) at a public offering price of $21.00 per share for net proceeds of $1,019.6 million, after deducting underwriters’ discounts (but excluding other offering expenses and reimbursements). ZoomInfo Technologies Inc. used all of the proceeds from the IPO to (i) purchase 48,528,783 newly issued HoldCo Units from ZoomInfo HoldCo for approximately $966.9 million (which ZoomInfo HoldCo in turn used to purchase the same number of newly issued OpCo Units from ZoomInfo OpCo); (ii) purchase 2,370,948 OpCo Units from certain Pre-IPO OpCo Unitholders for approximately $47.2 million; and (iii) fund $5.5 million of merger consideration payable to certain Pre-IPO Blocker Holders in connection with the Blocker Mergers (as defined below). Reorganization Transactions In connection with the IPO, the Company completed the following transactions (“Reorganization Transactions”): •ZoomInfo OpCo effected a four—for—one reverse unit split; •ZoomInfo Technologies Inc. formed a new merger subsidiary with respect to each of the Blocker Companies through which certain of our Pre-IPO Blocker Holders held their interests in ZoomInfo OpCo, each merger subsidiary merged with and into the respective Blocker Companies in reverse-subsidiary mergers, and the surviving entities merged with and into ZoomInfo Technologies Inc. (such mergers, the “Blocker Mergers”), which Blocker Mergers resulted in the Pre-IPO Blocker Holders receiving a combination of (i) shares of Class C common stock of ZoomInfo Technologies Inc. and (ii) a cash amount in respect of reductions in such Pre-IPO Blocker Holders’ equity interests, based on the initial offering price of the Class A common stock in the IPO; •certain Pre-IPO Owners acquired interests in ZoomInfo HoldCo as a result of the merger of an entity that held OpCo Units on behalf of such Pre-IPO Owners into ZoomInfo HoldCo (the “ZoomInfo HoldCo Contributions”) and the redemption of some OpCo Units pursuant to which the holders of such OpCo Units received HoldCo Units; and •the limited liability company agreement of each of ZoomInfo OpCo and ZoomInfo HoldCo was amended and restated to, among other things, modify their capital structure by reclassifying the interests held by the Pre-IPO OpCo Unitholders, the Continuing Class P Unitholders, and the Pre-IPO HoldCo Unitholders, resulting in OpCo Units of ZoomInfo OpCo, Class P Units of ZoomInfo OpCo, and HoldCo Units of ZoomInfo HoldCo, respectively (such reclassification, the “Reclassification”). We refer to the Reclassification, together with the Blocker Mergers and the ZoomInfo HoldCo Contributions, as the “Reorganization Transactions.” Following the Reorganization Transactions, ZoomInfo Technologies Inc. became a holding company, with its sole material asset being a controlling equity interest in ZoomInfo HoldCo, which became a holding company with its sole material asset being a controlling equity interest in ZoomInfo OpCo. ZoomInfo Technologies Inc. will operate and control all of the business and affairs, and consolidate the financial results, of ZoomInfo OpCo through ZoomInfo HoldCo and, through ZoomInfo OpCo and its subsidiaries, conduct our business. Accordingly, ZoomInfo Technologies Inc. consolidates the financial results of ZoomInfo HoldCo, and therefore ZoomInfo OpCo, and reports the non-controlling interests of the Pre-IPO HoldCo Units and Pre-IPO OpCo Units on its consolidated financial statements. As of March 31, 2021, ZoomInfo Technologies Inc. owned 99% of the outstanding HoldCo Units, and ZoomInfo HoldCo owned 48% of the outstanding OpCo Units. In connection with the Reorganization Transactions and the IPO, ZoomInfo Technologies Inc. entered into two tax receivable agreements. See Note 16.

Basis of Presentation and Summary of Significant Accounting Policies	3 Months Ended

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Note 2 - Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) pertaining to interim financial information. Certain information in footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP” or “GAAP”) has been condensed or omitted pursuant to those rules and regulations. The financial statements included in this report should be read in conjunction with the Company’s audited financial statements for the year ended December 31, 2020. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the operating results that may be expected for the full fiscal year ending December 31, 2021 or any future period. The accompanying unaudited consolidated financial statements contain all adjustments necessary for a fair statement of financial position as of March 31, 2021, and results of operations for the three months ended March 31, 2021 and 2020, and cash flows for the three months ended March 31, 2021 and 2020. The Condensed Consolidated Balance Sheet as of December 31, 2020 was derived from the audited consolidated balance sheets of the Company but does not contain all of the footnote disclosures from those annual financial statements. Accordingly, certain footnote disclosures normally included in annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the reporting period. These estimates relate to, but are not limited to, revenue recognition, allowance for doubtful accounts, contingencies, valuation and useful lives of long-lived assets, fair value of tangible and intangible assets acquired in business combinations, equity-based compensation, and income taxes, among other things. We base these estimates on historical and anticipated results, trends, and other assumptions with respect to future events that we believe are reasonable and evaluate our estimates on an ongoing basis. Given that estimates and judgments are required, actual results may differ from our estimates and such differences could be material to our consolidated financial position and results of operations. Principles of Consolidation The consolidated financial statements include the accounts of ZoomInfo Technologies Inc. and its subsidiaries that it controls due to ownership of a majority voting interest or pursuant to variable interest entity (“VIE”) accounting guidance. All intercompany transactions and balances have been eliminated in consolidation. ZoomInfo Technologies Inc., through our intermediate holding company ZoomInfo HoldCo, owns a minority economic interest in, but operates and has the power to control all of the businesses and affairs of, ZoomInfo OpCo. ZoomInfo Technologies Inc. has the obligation to absorb losses of, and receive benefits from, ZoomInfo OpCo, that could be significant. We determined that, as a result of the Reorganization Transactions described above, ZoomInfo OpCo is a VIE. Further, ZoomInfo Technologies Inc. has no contractual requirement to provide financial support to ZoomInfo OpCo and, for the three months ended March 31, 2021, ZoomInfo Technologies Inc. did not provide support to ZoomInfo OpCo. Accordingly, ZoomInfo Technologies Inc. is considered the primary beneficiary and consolidates ZoomInfo OpCo in the Company’s consolidated financial statements. The Reorganization Transactions were accounted for consistent with a combination of entities under common control. As a result, the financial reports filed with the SEC by the Company subsequent to the Reorganization Transactions are prepared “as if” ZoomInfo OpCo is the accounting predecessor of the Company. The historical operations of ZoomInfo OpCo are deemed to be those of the Company. Thus, the financial statements included in this report reflect (i) the historical operating results of ZoomInfo OpCo prior to the Reorganization Transactions; (ii) the consolidated results of ZoomInfo Technologies Inc. and ZoomInfo OpCo following the Reorganization Transactions; (iii) the assets and liabilities of ZoomInfo OpCo and ZoomInfo Technologies Inc. at their historical cost; and (iv) ZoomInfo Technologies Inc. equity structure for all periods presented. No step-up basis of intangible assets or goodwill was recorded. ZoomInfo OpCo has been determined to be our predecessor for accounting purposes and, accordingly, the consolidated financial statements for periods prior the Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes. The Company’s financial position, performance and cash flows effectively represent those of ZoomInfo OpCo as of and for all periods presented. Revenue Recognition The company derives revenue primarily from subscription services. Our subscription services consist of our SaaS applications and related access to our databases. Subscription contracts are generally based on the number of users that access our applications, the level of functionality that they can access, and the amount of data that a customer integrates with their systems. Our subscriptions contracts typically have a term of 1 to 3 years and are non-cancelable. We typically bill for services annually, semi-annually, or quarterly in advance of delivery. The Company accounts for revenue contracts with customers through the following steps: (1)identify the contract with a customer; (2)identify the performance obligations in the contract; (3)determine the transaction price; (4)allocate the transaction price; and (5)recognize revenue when or as the Company satisfies a performance obligation. We recognize revenue for subscription contracts on a ratable basis over the contract term based on the number of calendar days in each period, beginning on the date that our service is made available to the customer. Unearned revenue results from revenue amounts billed to customers in advance or cash received from customers in advance of the satisfaction of performance obligations. Determining the transaction price often involves judgments and estimates that can have a significant impact on the timing and amount of revenue reported. At times, the Company may adjust billing under a contract based on the addition of services or other circumstances, which are accounted for as variable consideration. The Company estimates these amounts based on historical experience and reduces revenue recognized. Cash, Cash Equivalents, and Short-term Investments Cash equivalents consist of highly liquid marketable debt securities with remaining maturities of three months or less at the date of purchase. We classify our investments in marketable securities as “available-for-sale.” We carry these investments at fair value, based on quoted market prices or other readily available market information. Unrealized gains and losses, net of taxes, are included in accumulated other comprehensive income, which is reflected as a separate component of stockholders’ equity in our Condensed Consolidated Balance Sheets. Gains and losses are determined using the specific identification method and recognized when realized in our Consolidated Statements of Operations. If we were to determine that an other-than-temporary decline in fair value has occurred, the amount of the decline related to a credit loss will be recognized in income. Fair Value Measurements The Company measures assets and liabilities at fair value based on an expected exit price, which represents the amount that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value: Level 1 - Observable inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities Level 2 - Other inputs that are directly or indirectly observable in the marketplace Level 3 - Unobservable inputs that are supported by little or no market activity, including the Company’s own assumptions in determining fair value The inputs or methodology used for valuing financial assets and liabilities are not necessarily an indication of the risk associated with investing in them. Concentrations of Credit Risk and Significant Customers Financial instruments that potentially subject us to concentrations of credit risk consist principally of cash and cash equivalents, short-term investments, and accounts receivable. The Company holds cash at major financial institutions that often exceed Federal Deposit Insurance Corporation (“FDIC”) insured limits. The Company manages its credit risk associated with cash concentrations by concentrating its cash deposits in high-quality financial institutions and by periodically evaluating the credit quality of the primary financial institutions holding such deposits. The carrying value of cash approximates fair value. Our investment portfolio is comprised of highly rated securities with a weighted-average maturity of less than 12 months in accordance with our investment policy which seeks to preserve principal and maintain a high degree of liquidity. Historically, the Company has not experienced any losses due to such cash concentrations. The Company does not have any off-balance-sheet credit exposure related to its customers. Concentrations of credit risk with respect to accounts receivable and revenue are limited due to a large, diverse customer base. We do not require collateral from clients. We maintain an allowance for doubtful accounts based upon the expected collectability of accounts receivable. The Company performs ongoing credit evaluations of its customers and maintains allowances for possible losses, which, when realized, have been within the range of management’s expectations. No single customer accounted for 10% or more of our revenue for the three months ended March 31, 2021 and 2020, or accounted for more than 10% of accounts receivable as of March 31, 2021 and December 31, 2020. Net assets located outside of the United States were immaterial as of March 31, 2021 and December 31, 2020. Accounts Receivable and Contract Assets Accounts receivable is comprised of invoices of revenue, net of allowance for doubtful accounts and does not bear interest. We consider receivables past due based on the contractual payment terms. Management’s evaluation of the adequacy of the allowance for doubtful accounts considers historical collection experience, changes in customer payment profiles, the aging of receivable balances, as well as current economic conditions, all of which may impact a customer’s ability to pay. Account balances are written-off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have significant bad debt experience with customers, and therefore, the allowance for doubtful accounts is immaterial as of March 31, 2021 and December 31, 2020. The assessment of variable consideration to be constrained is based on estimates, and actual consideration may vary from current estimates. As adjustments to these estimates become necessary, they are reported in earnings in the periods in which they become known. Changes in variable consideration are recorded as a component of net revenue. Contract assets represent a contractual right to consideration in the future. Contract assets are generated when contractual billing schedules differ from revenue recognition timing. Property and Equipment, Net Property and equipment is stated at cost, net of accumulated depreciation and amortization. All repairs and maintenance costs are expensed as incurred. Depreciation and amortization costs are expensed on a straight-line basis over the lesser of the estimated useful life of the asset or the remainder of the lease term for leasehold improvements. Qualifying internal use software costs incurred during the application development stage, which consist primarily of internal product development costs, outside services, and purchased software license costs, are capitalized and amortized over the estimated useful life of the asset. Estimated useful lives range from 3 years to 10 years. Deferred Commissions Certain sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. These sales commissions for initial contracts are capitalized and included in Deferred costs and other assets, net of current portion in our Condensed Consolidated Balance Sheets. Deferred sales commissions are amortized on a straight-line basis over the estimated period of benefit from the customer relationship which we have determined to be 1 and 3 years for renewals and new clients, respectively. We determined the period of benefit by taking into consideration our customer contracts, our technology, and other factors. Amortization expense is included in Sales and marketing expense on the Consolidated Statements of Operations. Commissions payable at March 31, 2021 were $19.7 million, of which the current portion of $17.4 million was included in Accrued expenses and other current liabilities in our Condensed Consolidated Balance Sheets, and the long-term portion of $2.3 million was included in Other long-term liabilities in our Condensed Consolidated Balance Sheets. Commissions payable at December 31, 2020 were $25.6 million, of which the current portion of $23.3 million was included in Accrued expenses and other current liabilities in our Condensed Consolidated Balance Sheets, and the long-term portion of $2.3 million was included in Other long-term liabilities in our Condensed Consolidated Balance Sheets. Certain commissions are not capitalized as they do not represent incremental costs of obtaining a contract. Such commissions are expensed as incurred. Advertising and Promotional Expenses The Company expenses advertising costs as incurred. Advertising expenses of $3.9 million and $2.9 million were recorded for the three months ended March 31, 2021 and 2020, respectively. Advertising expenses are included in Sales and marketing on the Consolidated Statements of Operations. Research and Development Research and development expenses consist primarily of compensation expense for our employees, including employee benefits, certain IT program expenses, facilities and related overhead costs. We continue to focus our research and development efforts on developing new products, adding new features and services, integrating acquired technologies, and increasing functionality. Expenditures for software developed or obtained for internal use are capitalized and amortized over a four-year period on a straight-line basis. Restructuring and Transaction-Related Expenses The Company defines restructuring and transaction related expenses as costs directly associated with acquisition or disposal activities. Such costs include employee severance and termination benefits, contract termination fees and penalties, and other exit or disposal costs. In general, the Company records involuntary employee-related exit and disposal costs when there is a substantive plan for employee severance and related costs that are probable and estimable. For one-time termination benefits for key members of management (i.e., no substantive plan), transaction related bonuses and employee retention costs, expense is recorded when the employees are entitled to receive such benefits and the amount can be reasonably estimated. Contract termination fees and penalties and other exit and disposal costs are generally recorded when incurred. Business Combinations We allocate purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values. The purchase price is determined based on the fair value of the assets transferred, liabilities assumed and equity interests issued, after considering any transactions that are separate from the business combination. The fair value of equity issued as part of a business combination is determined based on grant date stock price of the Company. The excess of fair value of purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets and contingent liabilities. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired customer bases, acquired technology and acquired trade names, useful lives, royalty rates, and discount rates. The estimates are inherently uncertain and subject to revision as additional information is obtained during the measurement period for an acquisition, which may last up to one year from the acquisition date. During the measurement period, we may record adjustments to the fair value of tangible and intangible assets acquired and liabilities assumed, with a corresponding offset to goodwill. After the conclusion of the measurement period or the final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to earnings. In addition, uncertain tax positions and tax-related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. We reevaluate these items based upon the facts and circumstances that existed as of the acquisition date, with any revisions to our preliminary estimates being recorded to goodwill, provided that the timing is within the measurement period. Subsequent to the measurement period, changes to uncertain tax positions and tax-related valuation allowances will be recorded to earnings. Goodwill and Acquired Intangible Assets Goodwill is calculated as the excess of the purchase consideration paid in a business combination over the fair value of the assets acquired less liabilities assumed. Goodwill is not amortized and is tested for impairment at least annually or when events and circumstances indicate that fair value of a reporting unit may be below its carrying value. The company has one reporting unit. We first assess qualitative factors to evaluate whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount or elect to bypass such assessment. If it is determined that it is more likely than not that the fair value of the reporting unit is less than its carrying value, or we elect to bypass the qualitative assessment, we perform a quantitative test by determining the fair value of the reporting unit. If the carrying value of the reporting unit exceeds the fair value, then an impairment loss is recognized for the difference. Acquired technology, customer lists, trade names or brand portfolios, and other intangible assets are related to previous acquisitions (see Note 7). Acquired intangible assets are amortized on a straight-line basis over the estimated period over which we expect to realize economic value related to the intangible asset. The amortization periods range from 2 years to 15 years. Any costs incurred to renew or extend the life of an intangible or long-lived asset are reviewed for capitalization. Indefinite-lived intangible assets consist primarily of brand portfolios acquired from Pre-Acquisition ZI and represent costs paid to legally register phrases and graphic designs that identify and distinguish products sold by the Company. Brand portfolios are not amortized, rather potential impairment is considered on an annual basis in the fourth quarter, or more frequently upon the occurrence of a triggering event, when circumstances indicate that the book value of trademarks are greater than their fair value. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than the carrying value as a basis to determine whether further impairment testing is necessary. No impairment charges relating to acquired goodwill or indefinite lived intangible assets were recorded for the three month periods ended March 31, 2021 and 2020. Impairment of Long-lived Assets Long-lived assets, such as property and equipment and acquired intangible assets, are reviewed for impairment whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the undiscounted future cash flows expected to be generated by the asset or group of assets. If the carrying amount of the asset exceeds the estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the estimated future cash flows of the asset. Leases We determine if an arrangement is or contains a lease at contract inception. Determining if a contract contains a lease requires judgement. In certain of our lease arrangements, primarily those related to our data center arrangements, judgment is required in determining if a contract contains a lease. For these arrangements, there is judgment in evaluating if the arrangement involves an identified asset that is physically distinct or whether we have the right to substantially all of the capacity of an identified asset that is not physically distinct. In arrangements that involve an identified asset, there is also judgment in evaluating if we have the right to direct the use of that asset. We do not have any finance leases. Operating leases are recorded in our Condensed Consolidated Balance Sheets. Right-of-use assets and lease liabilities are measured at the lease commencement date based on the present value of the fixed minimum remaining lease payments over the lease term, determined using the discount rate for the lease at the commencement date. Because the rate implicit in our leases is not readily determinable, we use our incremental borrowing rate as the discount rate, which approximates the interest rate at which we could borrow on a collateralized basis with similar terms and payments and in similar economic environments. Some leases include options to extend or options to terminate the lease prior to the stated lease expiration. Optional periods to extend a lease, including by not exercising a termination option, are included in the lease term when it is reasonably certain that the option will be exercised (or not exercised in the case of termination options). Operating lease expense is recognized on a straight-line basis over the lease term. We account for lease and non-lease components, principally common area maintenance for our facilities leases, as a single lease component. Short term leases, defined as leases having an original lease term less than or equal to one year, are excluded from our right-of-use assets and liabilities. Unearned Revenue Unearned revenue consists of customer payments and billings in advance of revenue being recognized from our subscription services. Unearned revenue that is anticipated to be recognized within the next 12 months is recorded as Unearned revenue, current portion and the remaining portion is included in Unearned revenue, net of current portion in our Condensed Consolidated Balance Sheets. Debt Issuance Costs Costs incurred in connection with the issuance of long-term debt are deferred and amortized as interest expense over the terms of the related debt using the effective interest method for term debt and on a straight-line basis for revolving debt. To the extent that the debt is outstanding, these amounts are reflected in the consolidated balance sheets as direct deductions from a combination of current and long-term portions of debt. Upon a refinancing or amendment, previously-capitalized debt issuance costs are expensed and included in loss on extinguishment of debt, if the Company determines that there has been a substantial modification of the related debt. If the Company determines that there has not been a substantial modification of the related debt, any previously-capitalized debt issuance costs are amortized as interest expense over the term of the new debt instrument. The company performs assessments of debt modifications at a lender-specific level for all syndicated financing arrangements. Tax Receivable Agreements In connection with our IPO, we entered into two Tax Receivable Agreements ("TRAs") with certain non-controlling interest owners (the “TRA Holders”). The TRAs generally provide for payment by the Company to the TRA Holders of 85% of the net cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the Company actually realizes or is deemed to realize in certain circumstances. The Company will retain the benefit of the remaining 15% of these net cash savings. Amounts payable under the TRA are accrued by a charge to income when it is probable that a liability has been incurred and the amount is estimable. TRA related liabilities are classified as current or noncurrent based on the expected date of payment and are included in the Company’s Condensed Consolidated Balance Sheets under the captions Current portion of tax receivable agreements liability and Tax receivable agreements liability, net of current portion, respectively. Subsequent changes to the measurement of the TRA liability are recognized in the statements of income as a component of other income (expense), net. See Note 16 for further details on the TRA liability. Income Taxes ZoomInfo Technologies Inc. is a corporation and is subject to U.S. federal as well as state income tax related to its ownership percentage in ZoomInfo Holdings LLC. ZoomInfo Holdings LLC is a limited liability company treated as a partnership for U.S. federal income tax purposes and files a U.S. Return of Partnership Income. Consequently, the members of ZoomInfo Holdings are taxed individually on their share of earnings for U.S. federal and state income tax purposes. However, ZoomInfo Holdings is subject to the Texas Margins Tax. Additionally, our operations in Israel are subject to local country income taxes. See Note 17 for additional information regarding income taxes. Deferred taxes are recorded using the asset and liability method, whereby tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. We regularly evaluate the valuation allowances established for deferred tax assets for which future realization is uncertain. In assessing the realizability of deferred tax assets, we consider both positive and negative evidence, including scheduled reversals of deferred tax assets and liabilities, projected future taxable income, tax planning strategies and results of recent operations. If, based on the weight of available evidence, it is more likely than not that the deferred tax assets will not be realized, a valuation allowance is recorded. Equity-Based Compensation Expense The Company periodically grants incentive units to employees and non-employees, which generally vest over a four-year period. Incentive units may be in the form of various equity-based awards such as restricted stock and restricted stock units, Class A stock options, and awards in one of the Company’s subsidiary partnerships which are typically in the form of profits interests. Profits interests are an interest in the increase in the value of the entity over a participation threshold. Prior to the IPO, the participation threshold was based on the valuation determined by the Board of Managers of OpCo Units on or around the grant date. Subsequent to the IPO, the participation threshold is determined by reference to the closing price of our Class A Common Stock from the preceding trading day. The holders of profits interests have the right to participate in distributions of profits only in excess of the participation threshold. Compensation expense for incentive units is measured at the estimated fair value of the incentive units and is included as compensation expense over the vesting period during which an employee provides service in exchange for the award. The Company uses a Black-Scholes option pricing model to determine the fair value of stock options and profits interests, as profits interests have certain economic similarities to options. The Black-Scholes option pricing model includes various assumptions, including the expected life of incentive units, the expected volatility and the expected risk-free interest rate. These assumptions reflect the Company’s best estimates, but they involve inherent uncertainties based on market conditions generally outside the control of the Company. As a result, if other assumptions are used, compensation cost could be materially impacted. The Company measures employee, non-employee, and board of director equity-based compensation on the grant date fair value basis. Equity-based compensation expense is recognized over the requisite service period of the awards. For equity awards that have a performance condition, the Company recognizes compensation expense based on its assessment of the probability that the performance condition will be achieved. The Company classifies equity-based compensation expense in its Consolidated Statements of Operations in the same manner in which the award recipient’s salary and related costs are classified or in which the award recipient’s service payments are classified. Recent Accounting Pronouncements Recent Accounting Pronouncements Not Yet Adopted In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform, if certain criteria are met. The standard applies to contract modifications that replace a reference rate affected by reference rate reform and contemporaneous modifications of other contract terms related to the replacement of the reference rate. Further, the standard provides exceptions to certain guidance in ASC 815, Derivatives and Hedging, related to changes to the critical terms of a hedging relationship due to reference rate reform and provides optional expedients for fair value, cash flow, and net investment hedging relationships for which the component excluded from the assessment of hedge effectiveness is affected by reference rate reform. The standard is effective for us as of March 12, 2020 through December 31, 2022, and we may elect to apply the provisions of the standard as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020 up to the date that the financial statements are available to be issued. Once elected, the provisions of the standard must be applied prospectively for all similar eligible contract modifications other than derivatives, which may be applied at a hedging relationship level. The standard would apply to our existing variable rate financing and derivatives designated as hedges if elected in the future. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in more timely recognition of credit losses. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company adopted ASU 2016-13 and ASU 2019-05 effective January 1, 2020. The adoption of this guidance was on a modified retrospective basis and did not have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), which amends disclosure requirements for fair value measurements by requiring new disclosures, modifying existing requirements, and eliminating others. The amendments are the result of a broader disclosure project, which aims to improve the effectiveness of disclosures. ASU No. 2018-13 is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company adopted ASU 2018-13 on January 1, 2020, and the adoption did not have a material effect on the Company’s financial statements or disclosures.

Revenue from Contracts with Customers

Note 3 - Revenue from Contracts with Customers

Revenue comprised the following service offerings:


	Three Months Ended March 31,
(in millions)	2021		2020
Subscription	$	151.4	$	101.2
Usage-based	1.9		1.0
Total revenue	$	153.3	$	102.2

Go-To-Market business intelligence tools are subscription services that allow customers access to our SaaS tools to support sales and marketing processes, which include data, analytics, and insights to provide accurate and comprehensive intelligence on organizations and professionals. Our customers use our platform to identify target customers and decision makers, obtain continually updated predictive lead and company scoring, monitor buying signals and other attributes of target companies, craft messages, engage via automated sales tools, and track progress through the deal cycle.

Usage-based revenue is comprised largely of email verification and intent-driven audience and targeting services, which are charged to our customers on a per unit basis based on their usage. We regularly observe that customers integrate our usage-based services into their internal workflows and use our services on an ongoing basis. We recognize usage-based revenue at the point in time the services are consumed by the customer, thereby satisfying our performance obligation.

Of the total revenue recognized in the three months ended March 31, 2021 and 2020, $108.3 million and $79.9 million were included in the unearned revenue balance as of December 31, 2020 and 2019, respectively. Revenue recognized from performance obligations satisfied (or partially satisfied) in previous periods was not material.

Revenues derived from customers and partners located outside the United States, as determined based on the address provided by our customers and partners, accounted for approximately 10% and 9% of our total revenues for the three months ended March 31, 2021 and 2020, respectively. We have no Company sales offices located in a foreign country as of March 31, 2021, and contracts denominated in currencies other than U.S. Dollar were not material for the three months ended March 31, 2021 and 2020.

Contract Assets and Unearned Revenue

The Company’s standard billing terms typically require payment at the beginning of each annual, semi-annual or quarterly period. Subscription revenue is generally recognized ratably over the contract term starting with when our service is made available to the customer. Usage-based revenue is recognized in the period services are utilized by our customers. The amount of revenue recognized reflects the consideration the Company expects to be entitled to receive in exchange for these services.

The Company records a contract asset when revenue recognized on a contract exceeds the billings to date for that contract. Unearned revenue results from cash received or amounts billed to customers in advance of revenue recognized upon the satisfaction of performance obligations. The unearned revenue balance is influenced by several factors, including seasonality, the compounding effects of renewals, invoice duration, invoice timing, dollar size, and new business timing within the quarter. The unearned revenue balance does not represent the total contract value of annual or multi-year, non-cancelable subscription agreements.

As of March 31, 2021 and December 31, 2020, the Company had contract assets of $2.2 million and $2.4 million, respectively, which are recorded as current assets within Prepaid expenses and other current assets in the Company’s Condensed Consolidated Balance Sheets. As of March 31, 2021 and December 31, 2020, the Company had unearned revenue of $261.9 million and $222.7 million, respectively.

ASC 606 requires the allocation of the transaction price to the remaining performance obligations of a contract. Transaction price allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes unearned revenue and unbilled amounts that will be recognized as revenue in future periods. Transaction price allocated to remaining performance obligations is influenced by several factors, including seasonality, the timing of renewals, and disparate contract terms. Revenue allocated to remaining performance obligations represents contracted revenue that has not yet been recognized, which includes unearned revenue and backlog. The Company's backlog represents installment billings for periods beyond the current billing cycle. The majority of the Company’s noncurrent remaining performance obligations will be recognized in the next 13 to 36 months.

The remaining performance obligations consisted of the following:


(in millions)	Recognized within one year		Noncurrent		Total

As of March 31, 2021	$	461.3	$	130.3	$	591.6

Cash and Cash Equivalents [Abstract]

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

2020 Acquisitions

The Company acquired all of the assets of Clickagy, LLC in October 2020 and all of the membership interests in EverString Technology, LLC in November 2020 for a total purchase consideration of $71.9 million. During the first quarter of fiscal year 2021, the Company recorded immaterial post-close net working capital adjustments. The preliminary purchase price allocation was updated to reflect the $0.2 million increase in consideration paid as well as to reflect the $0.2 million measurement period adjustment to unearned revenue. The Company included the financial results of these businesses in the consolidated financial statements from each date of acquisition. Transaction costs associated with each acquisition were not material. As part of the acquisitions, the Company agreed to issue $2.1 million of RSUs and agreed to pay $4.8 million of incentive compensation to acquired employees, subject to continued employment, to be recognized in the post-combination periods. The Company classifies compensation expense in its Consolidated Statements of Operations in the same manner in which the award recipient’s salary is classified.

The acquisition date fair value of the total consideration transferred was comprised of the following (in millions):


Cash	$	61.8
Purchase consideration liabilities	7.2
Issuance of 67,075 Class A shares	2.9
Total Purchase Consideration	$	71.9

The following table summarizes the aggregate fair values of the assets acquired and liabilities assumed, as of the date of the acquisitions (in millions):



Cash and cash equivalents	$	2.9
Accounts receivable	3.0
Prepaid expenses and other assets	1.1
Intangible assets	37.0
Accounts payable and other	(2.2)
Unearned revenue	(3.2)
Total identifiable net assets acquired	38.6
Goodwill	33.3
Total consideration	71.9
Issuance of 67,075 Class A shares	(2.9)
Cash acquired	(2.9)
Cash paid for acquisitions	$	66.1

The excess of purchase consideration over the fair value of net tangible and intangible assets acquired was recorded as goodwill. The fair values assigned to tangible and identifiable intangible assets acquired and liabilities assumed are based on management’s estimates and assumptions. The fair values of assets acquired and liabilities assumed may be subject to change as additional information is received, including the finalization of tax assets and liabilities.

The following table sets forth the components of identifiable intangible assets acquired and the estimated useful lives as of the dates of acquisition (in millions):


	Fair Value		Weighted Average Useful Life
Brand portfolio	$	2.0	6.5 years
Developed technology	29.6		7.0 years
Database	2.0		4.0 years
Customer relationships	3.4		9.3 years
Total intangible assets	$	37.0

Developed technology represents the fair value of the technology portfolios acquired. The goodwill is primarily attributed to the expanded market opportunities when integrating technology with the Company’s technology and the assembled workforce. The goodwill balance from both acquisitions is expected to be deductible for U.S. income tax purposes.

Pro forma information related to the acquisitions has not been presented as the impact was not material to the Company’s financial results.

Senior Notes

In February 2021, ZoomInfo Technologies LLC and ZoomInfo Finance Corp., indirect subsidiaries of ZoomInfo Technologies Inc., issued $350.0 million in aggregate principal amount of 3.875% Senior Notes due February 2029 to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. Interest on the Senior Notes is payable semi-annually in arrears beginning on August 1, 2021. The Issuers may redeem all or a part of the Notes at any time prior to February 1, 2024 at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus a make-whole premium and accrued and unpaid interest, if any, to, but not including, the redemption date. In addition, beginning on February 1, 2024, the Issuers may redeem all or a part of the Notes at a redemption price equal to 101.938% of the principal amount redeemed. The redemption price decreases to 100.969% and 100.000% of the principal amount redeemed on February 1, 2025 and February 1, 2026, respectively. In addition, at any time prior to February 1, 2024, the Issuers may redeem up to 40% of the Notes from the proceeds of certain equity offerings at a redemption price equal to 103.875% of the principal amount of the Senior Notes, plus accrued and unpaid interest.

First Lien Term Loan

In February 2021, we used all of the net proceeds from issuance of the Senior Notes, along with cash on hand, to prepay $356.4 million aggregate principal amount of our first lien term loans outstanding under the first lien credit agreement (the “Debt Prepayment”). Following the Debt Prepayment, $400.0 million aggregate principal amount of first lien term loans were outstanding under our First Lien Credit Agreement. In February 2021, we entered into an amendment to our first lien credit agreement (the “Second Amendment”), pursuant to which the Company completed a repricing of its First Lien Term Loan Facility, which decreased the interest rate by 75 basis points to LIBOR plus 3.00% per annum. The Company recognized $5.9 million in the three months ended March 31, 2021 within Loss on debt extinguishment on the Consolidated Statements of Operations, primarily comprised of the write-off of unamortized issuance costs associated with the Debt Prepayment.

The first lien term debt has a variable interest rate whereby the Company can elect to use a Base Rate or the London Interbank Offer Rate (“LIBOR”) plus an applicable rate. The applicable rate is 2.00% for Base Rate loans or 3.00% for LIBOR Based Loans. The effective interest rate on the first lien debt was 3.5% and 4.3% as of March 31, 2021 and December 31, 2020, respectively.

First Lien Revolving Credit Facility

Pursuant to the Second Amendment to the First Lien Credit Agreement entered into in February 2021, the Company increased the aggregate commitments to $250.0 million under our first lien revolving credit facility. The Second Amendment also provided an extension of the maturity date of our first lien revolving credit facility to November 2025. The first lien revolving debt has a variable interest rate whereby the Company can elect to use a Base Rate or the London Interbank Offer Rate (“LIBOR”) plus an applicable rate. The applicable margin is 1.00% to 1.25% for Base Rate loans or 2.00% to 2.25% for LIBOR Based Loans, depending on the Company’s leverage.

On March 25th, 2020, the Company drew down $35.0 million under the revolving credit facility. On June 8, 2020, the Company paid off the outstanding $35.0 million balance of the revolving credit facility with proceeds from the IPO. The effective interest rate was 3.7% as of the repayment date. Immaterial debt issuance costs were incurred in connection with the entry into the revolving credit facility. These debt issuance costs are amortized into interest expense over the expected life of the arrangement. Unamortized debt issuance costs included in Deferred costs, net of current portion on the accompanying Condensed Consolidated Balance Sheets were immaterial as of March 31, 2021 and December 31, 2020.

First Lien Credit Agreement

The First Lien Credit Agreement is secured by substantially all the productive assets of the Company. The First Lien Credit Agreement contains a number of covenants that restrict, subject to certain exceptions, the Company’s ability to, among other things:

•incur additional indebtedness;

•create or incur liens;

•engage in certain fundamental changes, including mergers or consolidations;

•sell or transfer assets;

•pay dividends and distributions on our subsidiaries’ capital stock;

•make acquisitions, investments, loans or advances;

•engage in certain transactions with affiliates; and

•enter into negative pledge clauses and clauses restricting subsidiary distributions.

If the Company draws more than $87.5 million of the revolving credit loan, the revolving credit loan is subject to a springing financial covenant pursuant to which the consolidated first lien net leverage ratio must not exceed 5.00 to 1.00. The credit agreements also contain certain customary affirmative covenants and events of default, including a change of control. If an event of default occurs, the lenders under the credit agreements will be entitled to take various actions, including the acceleration of amounts due under the credit agreements and all actions permitted to be taken by a secured creditor.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging Activities

Note 9 - Derivatives and Hedging Activities

We are exposed to changes in interest rates, primarily relating to changes in interest rates on our first lien term loan. Consequently, from time to time, we may use interest rate swaps or other financial instruments to manage our exposure to interest rate movements. Our primary objective in holding derivatives is to reduce the volatility of cash flows associated with changes in interest rates. We do not enter into derivative transactions for speculative or trading purposes.

We recognize derivative instruments and hedging activities on a gross basis as either assets or liabilities on the Company’s Condensed Consolidated Balance Sheets and measure them at fair value. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the earnings effect of the hedged forecasted transactions in a cash flow hedge. For derivatives designated as cash flow hedges, the change in the estimated fair value of the effective portion of the derivative is recognized in Accumulated other comprehensive income (loss) on our Condensed Consolidated Balance Sheets. To receive hedge accounting treatment, all hedging relationships are formally documented at the inception of the hedge, and the hedges must be highly effective in offsetting changes to future cash flows on hedged transactions.

In February 2021, concurrent with the prepayment of $356.4 million aggregate principal amount of the first lien term loans outstanding under the First Lien Credit Agreement, we fully dedesignated the interest rate cap contract and partially dedesignated $100.0 million of the notional amount of one of the forward-starting interest rate swap contracts. As of March 31, 2021, $500.0 million of the notional amount of the interest rate cap contract and $100.0 million of the notional amount of one of the forward-starting interest rate swap contracts are not designated as accounting hedges. Gains and losses resulting from valuation adjustments on dedesignated portions of our derivative contracts subsequent to dedesignation of hedge accounting are recorded within Interest expense, net in our Consolidated Statements of Operations. As it is not probable the forecasted transaction will not occur, the amounts in Accumulated other comprehensive income (loss) as of the date of dedesignation will be released based on our original forecast.

As of March 31, 2021, the Company had the following outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk ($ in millions):


Interest Rate Derivatives (Level 2)	Number of Instruments	Notional Aggregate Principal Amount		Interest Cap / Swap Rate		Maturity Date
Interest rate cap contract	One	$	—	3.500	%	April 30, 2024
Interest rate swap contracts	Two	$	350.0	2.301	%	April 29, 2022
Forward-starting interest rate swap contracts - April 2022	Two	$	400.0	0.370	%	January 30, 2026

The following table summarizes the fair value and presentation in the Company’s Condensed Consolidated Balance Sheets for derivatives as of March 31, 2021 and December 31, 2020 (in millions):

(2) Included in Other long-term liabilities on our Condensed Consolidated Balance Sheets.

(3) Included in Deferred costs and other assets, net of current portion on our Condensed Consolidated Balance Sheets.

The change in fair value of any derivative instruments was recorded, net of income tax, in Accumulated other comprehensive income (loss) (“AOCI”) on the Company’s Condensed Consolidated Balance Sheets to the extent the agreements were designated as effective hedges. In the period that the hedged item affects earnings, such as when interest payments are made on the Company’s variable-rate debt, we reclassify the related gain or loss on the interest rate swap cash flow hedges and any receipts on the cap to Interest expense, net and as operating cash flows in our Consolidated Statements of Cash Flows in the period settled in cash. Income tax effects from changes in fair value of derivative instruments are recorded in our Consolidated Statements of Operations when the derivative instruments are settled. Over the next 12 months, we expect to reclassify approximately $5.9 million into interest expense from AOCI.

Refer to the Company’s Consolidated Statements of Comprehensive Income (Loss) for amounts reclassified from AOCI into earnings related to the Company’s Derivative Instruments designated as cash flow hedging instruments for each of the reporting periods.

Fair Value Disclosures [Abstract]

Fair Value

Note 10 - Fair Value

The Company's financial instruments consist principally of cash and cash equivalents, short-term investments, prepaid expenses and other current assets, accounts receivable, and accounts payable, accrued expenses, and long-term debt. The carrying value of cash and cash equivalents, prepaid expenses and other current assets, accounts receivable, accounts payable, and accrued expenses approximate fair value, primarily due to short maturities. We classify our money market mutual funds as Level 1 of the fair value hierarchy. We classify our corporate debt securities, securities guaranteed by U.S. government, and other governmental securities as Level 2 of the fair value hierarchy. The carrying values of the Company's debt instruments approximate their fair value based on Level 2 inputs since the instruments carry variable interest rates based on LIBOR or other applicable reference rates.

The Company has elected to use the income approach to value the interest rate derivatives using observable Level 2 market expectations at measurement date and standard valuation techniques to convert future amounts to a single present amount (discounted) reflecting current market expectations about those future amounts. Level 2 inputs for the derivative valuations are limited to quoted prices for similar assets or liabilities in active markets (specifically futures contracts) and inputs other than quoted prices that are observable for the asset or liability (specifically LIBOR cash and swap rates, implied volatility for options, caps and floors, basis swap adjustments, overnight indexed swap (“OIS”) short term rates and OIS swap rates, when applicable, and credit risk at commonly quoted intervals). Mid-market pricing is used as a practical expedient for most fair value measurements. Key inputs, including the cash rates for very short term, futures rates and swap rates beyond the derivative maturity are interpolated to provide spot rates at resets specified by each derivative (reset rates are then further adjusted by the basis swap, if necessary). Derivatives are discounted to present value at the measurement date at LIBOR rates unless they are fully collateralized. Fully collateralized derivatives are discounted to present value at the measurement date at OIS rates (short term OIS rates and long term OIS swap rates).

Inputs are collected from SuperDerivatives, an independent third-party derivative pricing data provider, as of the close on the last day of the period. The valuation of the interest rate swaps also take into consideration estimates of our own, as well as counterparty’s, risk of non-performance under the contract.

We estimate the value of other long-lived assets that are recorded at fair value on a non-recurring basis based on a market valuation approach. We use prices and other relevant information generated primarily by recent market transactions involving similar or comparable assets, as well as our historical experience in divestitures, acquisitions and real estate transactions. Additionally, we may use a cost valuation approach to value long-lived assets when a market valuation approach is unavailable. Under this approach, we determine the cost to replace the service capacity of an asset, adjusted for physical and economic obsolescence. When available, we use valuation inputs from independent valuation experts, such as real estate appraisers and brokers, to corroborate our estimates of fair value. Real estate appraisers’ and brokers’ valuations are typically developed using one or more valuation techniques including market, income and replacement cost approaches. Because these valuations contain unobservable inputs, we classify the measurement of fair value of long-lived assets as Level 3.

The fair value (in millions) of our financial assets and (liabilities) was determined using the following inputs:

Earnings Per Share

Note 13 - Earnings Per Share

Basic earnings per share of Class A and Class C common stock is computed by dividing net income attributable to ZoomInfo Technologies, Inc. by the weighted-average number of shares of Class A and Class C common stock outstanding during the period. Diluted earnings per share of Class A and Class C common stock is computed by dividing net income attributable to ZoomInfo Technologies, Inc., adjusted for the assumed exchange of all potentially dilutive instruments for Class A common stock, by the weighted-average number of shares of Class A and Class C common stock outstanding, adjusted to give effect to potentially dilutive elements.

Prior to the IPO, the ZoomInfo OpCo membership structure included Series A Preferred Units, Preferred units, Common units, and Profits Interests in the form of Class P Units. The Company analyzed the calculation of earnings per unit for periods prior to the IPO and determined that it resulted in values that would not be meaningful to the users of these unaudited consolidated financial statements. Therefore, earnings per share information has not been presented for the three months ended March 31, 2020.

Leases

Note 14 - Leases

The Company has operating leases for corporate offices under non-cancelable agreements with various expiration dates. Our leases do not have significant rent escalation, holidays, concessions, material residual value guarantees, material restrictive covenants, or contingent rent provisions. Our leases include both lease (e.g., fixed payments including rent, taxes, and insurance costs) and non-lease components (e.g., common-area or other maintenance costs) which are accounted for as a single lease component. In addition, we have elected the practical expedient to exclude short-term leases, which have an original lease term of less than one year, from our right-of-use assets and lease liabilities as well as the package of practical expedients relating to adoption of Topic 842.

The Company also subleases a former corporate office space. The sublease has a remaining lease term of less than one year. Sublease income, which is recorded as a reduction of rent expense and allocated to the appropriate financial statement line item to arrive at Income from operations in the Consolidated Statements of Operations was immaterial for the three months ended March 31, 2021 and 2020.

During the three months ended March 31, 2021, the Company executed an agreement to sublease our existing Waltham office space for the remainder of our lease term in anticipation of our office relocation which will commence in June 2021. Sublease income will be recorded as a reduction of rent expense and allocated to the appropriate financial statement line item to arrive at Income from operations in the Consolidated Statements of Operations. In connection with these activities, and as referenced in Note 6 - Property and Equipment, we recorded a cumulative impairment charge of $1.5 million to reduce the carrying values of our existing Waltham right-of-use asset and related leasehold improvements to their respective fair values.

The following are additional details related to leases recorded on our balance sheet as of March 31, 2021 and December 31, 2020:

Equity-based Compensation

Note 15 - Equity-based Compensation

2020 Omnibus Incentive Plan - On May 27, 2020, the Board of Directors of the Company (the “Board”) adopted the ZoomInfo Technologies Inc. 2020 Omnibus Incentive Plan (the “Omnibus Plan”). The Omnibus Plan provides for potential grants of the following awards with respect to shares of the Company’s Class A common stock and OpCo Units: (i) incentive stock options qualified as such under U.S. federal income tax laws; (ii) non-qualified stock options or any other form of stock options; (iii) stock appreciation rights; (iv) restricted stock; (v) restricted stock units; (vi) OpCo Units, and (vii) other equity-based and cash-based incentive awards as determined by the compensation committee of the Board or any properly delegated subcommittee.

The maximum aggregate number of shares of the Company’s Class A common stock that may be issued pursuant to awards under the Omnibus Plan shall not exceed 18,650,000 shares (including OpCo Units or other securities which have been issued under the plan and can be exchanged or converted into shares of Class A common stock) (the “Plan Share Reserve”). The Omnibus Plan also contains a provision that will add an additional number of shares of Class A common stock to the Plan Share Reserve on the first day of each year starting with January 1, 2021, equal to the lesser of (i) the positive difference between (x) 5% of the outstanding Class A Common Stock on the last day of the immediately preceding year, and (y) the Plan Share Reserve on the last day of the immediately preceding year, and (ii) a lower number of shares of Class A Common Stock as may be determined by the Board.

The Company currently has equity-based compensation awards outstanding as follows: Restricted Stock Units, Class A Common Stock Options, HoldCo Units, OpCo Units, Class P Units, and LTIP units. In addition, the Company recognizes equity-based compensation expense from awards granted to employees by noncontrolling interest holders of HoldCo Units and OpCo Units as further described below under HSKB Incentive Units.

In connection with the Reorganization Transactions and the IPO, 1,950,930 Class P Units held directly by employees of the Company or indirectly through DiscoverOrg Management Holdings, LLC, were converted into 1,325,330 unvested HoldCo Units and 576,708 unvested Options based on their respective participation thresholds and the IPO price of $21.00 per share. In connection with this conversion of Class P Units as part of the Reorganization Transactions, the Company incurred incremental grant date fair value of $4.0 million. The HoldCo Units and Options issued upon the conversion remain subject to the same service vesting requirements of the original Class P Units.

Except where indicated otherwise, the equity-based compensation awards described below are subject to time-based service requirements. For grants issued prior to June 2020, the service vesting condition is generally over four years with 50% vesting on the two year anniversary of the grant date of the award and the remainder vesting monthly thereafter. For awards made after May 2020, the service vesting condition is generally over four years with 25% vesting on the one year anniversary of the grant date of the award and 6.25% vesting quarterly thereafter.

Restricted Stock Units

Restricted Stock Unit (“RSU”) activity was as follows during the periods indicated:


	Three Months Ended March 31, 2021
	Restricted Stock Units	Weighted Average Grant Date Fair Value
Unvested at beginning of period	985,398	$	28.84

Class A Common Stock Options

Outstanding options activity was as follows during the period indicated:


	Three Months Ended March 31, 2021
	Options	Weighted Average Exercise Price
Unvested at beginning of period	552,440	$	21.00

Forfeited	(3,561)	$	21.00
Unvested at end of period	441,061	$	21.00

Options have a maximum contractual term of ten years. The aggregate intrinsic value and weighted average remaining contractual terms of Options outstanding and Options exercisable were as follows as of March 31, 2021.


	March 31, 2021
Aggregate intrinsic value (in millions)
Unit Options outstanding	$	14.6
Unit Options exercisable	$	2.3
Weighted average remaining contractual life (in years)
Unit Options outstanding	9.2 years
Unit Options exercisable	9.2 years

All Options outstanding were issued at the time of the IPO in 2020. No additional options have been issued to date. The fair value of Class A stock options granted at the time of the IPO was determined using the Black-Scholes option pricing model. We estimated the future stock price volatility based on the volatility of a set of publicly traded comparable companies with a look back period consistent with the expected life. The estimated life for the units was based on the expected hold period of private equity owners. The risk-free rate is based on the rate for a U.S. government security with the same estimated life at the time of grant.

HoldCo Units

Unvested HoldCo Unit activity was as follows during the periods indicated:

Class P Units

Class P Units were issued under both the prior and current LLC agreement of ZoomInfo OpCo. Class P Unit activity was as follows during the periods indicated:


	Three Months Ended March 31, 2021			Three Months Ended March 31, 2020
	Class P Units	Weighted Average Participation Threshold		Class P Units
Unvested at beginning of period	8,796,642	$	6.59	16,893,603

Unvested at end of period	6,019,149	$	6.76	15,716,246

In September 2019, ZoomInfo OpCo expanded its employee incentive programs under a newly-formed upper tier entity DiscoverOrg Management Holdings, LLC (“Management Holdings”), established to issue Incentive Units to employees of the Company. Through this newly formed upper tier entity, Class P Units were issued by Management Holdings to employees, directors, and consultants or advisors of the Company, and ZoomInfo OpCo issued corresponding Class P Units to Management Holdings. The cancellation or forfeiture of any Management Holdings’ Class P Units automatically results in a cancellation of an equal number of ZoomInfo OpCo’s Class P Units. Management Holdings was subsequently merged with and into ZoomInfo HoldCo in connection with the Reorganization Transactions and IPO. Class P Units issued directly by ZoomInfo OpCo and by Management Holdings are combined in the table above.

The fair value of these Class P Units was determined using the Black-Scholes option pricing model. We estimated the future stock price volatility based on the volatility of a set of publicly traded comparable companies with a look back period consistent with the expected life. The estimated life for the units was based on the expected holding period of private equity owners. The risk-free rate is based on the rate for a U.S. government security with the same estimated life at the time of grant. There were no grants of Class P Units during the three months ended March 31, 2021 and 2020.

LTIP Units

LTIP Unit activity was as follows during the periods indicated:


	Three Months Ended March 31, 2021
	LTIP Units	Weighted Average Participation Threshold
Unvested at beginning of period	47,620	$	21.00

Granted	247,045	$	52.42


Unvested at end of period	294,665	$	47.34

HSKB Incentive Units

After selling units to TA Associates and funds affiliated with 22C Capital LLC, the founders of the Company contributed membership units of ZoomInfo OpCo into an upper tier entity, HSKB Funds, LLC, which is controlled by the current CEO of the Company (“HSKB Manager”). In connection with the Reorganization Transactions, HSKB was reorganized into HSKB I and HSKB II (together, “HSKB”), with HSKB I owning OpCo Units and HSKB II owning HoldCo Units. HSKB may issue LLC units to employees of the Company (“HSKB Grant”) in the form of Class 1 units and Class 2 units, with a Class 1 unit being exchangeable into one share of Class A Common Stock, and a Class 2 unit equal to any residual interests in HSKB upon liquidation. These awards are recorded in accordance with the measurement and recognition criteria of ASC 718 for awards made to non-employees.

Prior to December 2019, most HSKB Grants were issued with a performance vesting condition wherein the award vests upon the cumulative change of more than 90% of the membership interests in the Company. In December 2019, unvested HSKB Grants were modified to add an alternative vesting condition and modify the forfeiture provisions, wherein 50% of an HSKB Grant will no longer be subject to forfeiture and will be eligible to vest on the later of September 1, 2020 or two years following the award grant date, and 1/48th will no longer be subject to forfeiture and be eligible to vest on the first day of each subsequent month. This additional vesting condition (but not the forfeiture modification) is conditioned upon the ability to exchange the HSKB Units for the Class A Common Stock of the Company after an IPO. This modification affected 142 grantees at the time and resulted in an increase in unrecognized equity-based compensation cost related to the HSKB Grants of approximately $88.4 million. Upon completion of the IPO in June 2020, this performance condition was satisfied and the Company began to recognize compensation cost under these awards on a straight-line basis in the same manner as if the Company had paid cash in lieu of awarding the HSKB Grants, per the requirements of ASC 718.

In 2018, in connection with the Carlyle Investment described above, holders of HSKB Grants received $21.8 million in cash distributions. In addition, HSKB allocated $31.3 million to be paid over three years from 2019 to 2021 if the holder of the HSKB Grant remains employed by the Company as of the payment date. On March 31, 2020, HSKB allocated an additional $5.3 million to be paid out over four years, starting with March 31, 2020, to holders of HSKB Grants who received their grants after the March 2018 Carlyle Investment, subject to the holders continued employment by the Company. During the three months ended March 31, 2021, HSKB paid $9.0 million from allocated funds and has $3.1 million remaining that it has allocated to be paid through 2023.

HSKB Phantom Units - In December 2019, HSKB I adopted the HSKB Funds, LLC 2019 Phantom Unit Plan wherein HSKB may grant Phantom Units (“HSKB Phantom Units”) to employees of the Company. HSKB Phantom Units are recorded in accordance with the measurement and recognition criteria of ASC 718 for awards made to non-employees. HSKB Phantom Units represent the economic equivalent of one Class A Common Share in the Company and generally have the same vesting and forfeiture conditions as the modified HSKB Grants (see HSKB Incentive Units above). In connection with the Reorganization Transactions, all HSKB Phantom Units were moved from HSKB I to HSKB II. Within 30 days of the later of the date upon which a Phantom Unit vests and the date that HSKB II is capable of making an exchange of a corresponding ZoomInfo HoldCo Common Unit for Class A Common Stock, HSKB II must settle the HSKB Phantom Unit in exchange for either (1) cash or (2) Class A Common Stock as determined by the HSKB Manager, in each case, equal to the fair market value of such Common Unit at the time of such exchange. The HSKB Incentive Units and HSKB Phantom Units both had time-based vesting conditions that were conditional upon the completion of an IPO.

Compensation expense incurred from all the equity-based incentive awards described above was the following (in millions):

Tax Receivable Agreements	3 Months Ended
Tax Receivable Agreements	Mar. 31, 2021
Tax Receivable Agreements [Abstract]
Tax Receivable Agreements	Note 16 - Tax Receivable Agreements In connection with the Reorganization Transactions and the IPO, the Company entered into (i) the Exchange Tax Receivable Agreement with certain Pre-IPO OpCo Unitholders and (ii) the Reorganization Tax Receivable Agreement with the Pre-IPO Blocker Holders (collectively, the “Tax Receivable Agreements”). These Tax Receivable Agreements provide for the payment by ZoomInfo Technologies Inc. or any member of its affiliated, consolidated, combined, or unitary tax group (collectively, the “ZoomInfo Tax Group”) to such Pre-IPO Owners and certain Pre-IPO HoldCo Unitholders of 85.0% of the benefits, if any, the ZoomInfo Tax Group actually realizes, or is deemed to realize in certain circumstances, as a result of certain tax attributes and benefits covered by the Tax Receivable Agreements. The Exchange Tax Receivable Agreement provides for the payment by members of the ZoomInfo Tax Group to certain Pre-IPO OpCo Unitholders and certain Pre-IPO HoldCo Unitholders of 85.0% of the benefits, if any, that the ZoomInfo Tax Group realizes as a result of (i) the ZoomInfo Tax Group’s allocable share of existing tax basis acquired in the IPO and (ii) increases in the ZoomInfo Tax Group’s allocable share of existing tax basis and tax basis adjustments that will increase the tax basis of the tangible and intangible assets of the ZoomInfo Tax Group as a result of sales or exchanges of OpCo Units for shares of Class A common stock after the IPO, and certain other tax benefits, including tax benefits attributable to payments under the Exchange Tax Receivable Agreement. The Reorganization Tax Receivable Agreement provides for the payment by ZoomInfo Technologies Inc. to the Pre-IPO Blocker Holders and certain Pre-IPO HoldCo Unitholders of 85.0% of the benefits, if any, that the ZoomInfo Tax Group realizes as a result of the ZoomInfo Tax Group’s utilization of certain tax attributes of the Blocker Companies (including the ZoomInfo Tax Group’s allocable share of existing tax basis acquired in the Reorganization Transactions), and certain other tax benefits, including tax benefits attributable to payments under the Reorganization Tax Receivable Agreement. The Company expects to benefit from the remaining 15.0% of any of cash savings that it realizes. The Company expects to obtain an increase in its share of the tax basis in the net assets of ZoomInfo HoldCo when OpCo Units are exchanged by Pre-IPO OpCo Unitholders. The Company intends to treat any redemptions and exchanges of OpCo Units as direct purchases for U.S. federal income tax purposes. These increases in tax basis may reduce the amounts that it would otherwise pay in the future to various tax authorities. They may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. As of March 31, 2021, the Company had a liability of $390.2 million related to its projected obligations under the Tax Receivable Agreements in connection with the Reorganization Transactions and OpCo units exchanged. Tax Receivable Agreements related liabilities are classified as current or noncurrent based on the expected date of payment and are included in the Company’s Condensed Consolidated Balance Sheets under the captions Current portion of tax receivable agreements liability and Tax receivable agreements liability, net of current portion, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Note 17 - Income Taxes The Company recorded $49.7 million of income tax expense and $0.4 million of income tax benefit for the three months ended March 31, 2021 and 2020, respectively. The Company’s estimated effective tax rate for the three months ended March 31, 2021 was 314.5%. The Company’s estimated annual effective tax rate differs from the statutory rate of 21.0% primarily due to the recognition of non-cash tax expense resulting from a shift in GAAP basis from a non-taxable entity to a taxable entity. The Company does not believe it has any significant uncertain tax positions and therefore has no unrecognized tax benefits as of March 31, 2021, that if recognized, would affect the annual effective tax rate.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Revenue from Contract with Customer [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) pertaining to interim financial information. Certain information in footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP” or “GAAP”) has been condensed or omitted pursuant to those rules and regulations. The financial statements included in this report should be read in conjunction with the Company’s audited financial statements for the year ended December 31, 2020.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make certain estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the reporting period. These estimates relate to, but are not limited to, revenue recognition, allowance for doubtful accounts, contingencies, valuation and useful lives of long-lived assets, fair value of tangible and intangible assets acquired in business combinations, equity-based compensation, and income taxes, among other things. We base these estimates on historical and anticipated results, trends, and other assumptions with respect to future events that we believe are reasonable and evaluate our estimates on an ongoing basis. Given that estimates and judgments are required, actual results may differ from our estimates and such differences could be material to our consolidated financial position and results of operations.
Organization and Principles of Consolidation	Organization ZoomInfo Technologies Inc. was formed on November 14, 2019 with no operating assets or operations as a Delaware corporation for the purposes of facilitating an initial public offering (“IPO”) and other related transactions in order to carry on the business of ZoomInfo Holdings LLC (“ZoomInfo OpCo”) (formerly known as DiscoverOrg Holdings, LLC), a Delaware limited liability company. Following consummation of the Reorganization Transactions (as described below), ZoomInfo OpCo became a direct subsidiary of ZoomInfo Intermediate Holdings LLC (“ZoomInfo HoldCo”), a Delaware limited liability company and an indirect subsidiary of ZoomInfo Technologies Inc. Principles of Consolidation The consolidated financial statements include the accounts of ZoomInfo Technologies Inc. and its subsidiaries that it controls due to ownership of a majority voting interest or pursuant to variable interest entity (“VIE”) accounting guidance. All intercompany transactions and balances have been eliminated in consolidation. ZoomInfo Technologies Inc., through our intermediate holding company ZoomInfo HoldCo, owns a minority economic interest in, but operates and has the power to control all of the businesses and affairs of, ZoomInfo OpCo. ZoomInfo Technologies Inc. has the obligation to absorb losses of, and receive benefits from, ZoomInfo OpCo, that could be significant. We determined that, as a result of the Reorganization Transactions described above, ZoomInfo OpCo is a VIE. Further, ZoomInfo Technologies Inc. has no contractual requirement to provide financial support to ZoomInfo OpCo and, for the three months ended March 31, 2021, ZoomInfo Technologies Inc. did not provide support to ZoomInfo OpCo. Accordingly, ZoomInfo Technologies Inc. is considered the primary beneficiary and consolidates ZoomInfo OpCo in the Company’s consolidated financial statements.
Reorganization Transactions	We refer to the Reclassification, together with the Blocker Mergers and the ZoomInfo HoldCo Contributions, as the “Reorganization Transactions.” Following the Reorganization Transactions, ZoomInfo Technologies Inc. became a holding company, with its sole material asset being a controlling equity interest in ZoomInfo HoldCo, which became a holding company with its sole material asset being a controlling equity interest in ZoomInfo OpCo. ZoomInfo Technologies Inc. will operate and control all of the business and affairs, and consolidate the financial results, of ZoomInfo OpCo through ZoomInfo HoldCo and, through ZoomInfo OpCo and its subsidiaries, conduct our business. Accordingly, ZoomInfo Technologies Inc. consolidates the financial results of ZoomInfo HoldCo, and therefore ZoomInfo OpCo, and reports the non-controlling interests of the Pre-IPO HoldCo Units and Pre-IPO OpCo Units on its consolidated financial statements.The Reorganization Transactions were accounted for consistent with a combination of entities under common control. As a result, the financial reports filed with the SEC by the Company subsequent to the Reorganization Transactions are prepared “as if” ZoomInfo OpCo is the accounting predecessor of the Company. The historical operations of ZoomInfo OpCo are deemed to be those of the Company. Thus, the financial statements included in this report reflect (i) the historical operating results of ZoomInfo OpCo prior to the Reorganization Transactions; (ii) the consolidated results of ZoomInfo Technologies Inc. and ZoomInfo OpCo following the Reorganization Transactions; (iii) the assets and liabilities of ZoomInfo OpCo and ZoomInfo Technologies Inc. at their historical cost; and (iv) ZoomInfo Technologies Inc. equity structure for all periods presented. No step-up basis of intangible assets or goodwill was recorded.ZoomInfo OpCo has been determined to be our predecessor for accounting purposes and, accordingly, the consolidated financial statements for periods prior the Reorganization Transactions have been adjusted to combine the previously separate entities for presentation purposes. The Company’s financial position, performance and cash flows effectively represent those of ZoomInfo OpCo as of and for all periods presented
Revenue Recognition	Revenue Recognition The company derives revenue primarily from subscription services. Our subscription services consist of our SaaS applications and related access to our databases. Subscription contracts are generally based on the number of users that access our applications, the level of functionality that they can access, and the amount of data that a customer integrates with their systems. Our subscriptions contracts typically have a term of 1 to 3 years and are non-cancelable. We typically bill for services annually, semi-annually, or quarterly in advance of delivery. The Company accounts for revenue contracts with customers through the following steps: (1)identify the contract with a customer; (2)identify the performance obligations in the contract; (3)determine the transaction price; (4)allocate the transaction price; and (5)recognize revenue when or as the Company satisfies a performance obligation. We recognize revenue for subscription contracts on a ratable basis over the contract term based on the number of calendar days in each period, beginning on the date that our service is made available to the customer. Unearned revenue results from revenue amounts billed to customers in advance or cash received from customers in advance of the satisfaction of performance obligations. Determining the transaction price often involves judgments and estimates that can have a significant impact on the timing and amount of revenue reported. At times, the Company may adjust billing under a contract based on the addition of services or other circumstances, which are accounted for as variable consideration. The Company estimates these amounts based on historical experience and reduces revenue recognized. Deferred Commissions Certain sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. These sales commissions for initial contracts are capitalized and included in Deferred costs and other assets, net of current portion in our Condensed Consolidated Balance Sheets. Deferred sales commissions are amortized on a straight-line basis over the estimated period of benefit from the customer relationship which we have determined to be 1 and 3 years for renewals and new clients, respectively. We determined the period of benefit by taking into consideration our customer contracts, our technology, and other factors. Amortization expense is included in Sales and marketing expense on the Consolidated Statements of Operations. Commissions payable at March 31, 2021 were $19.7 million, of which the current portion of $17.4 million was included in Accrued expenses and other current liabilities in our Condensed Consolidated Balance Sheets, and the long-term portion of $2.3 million was included in Other long-term liabilities in our Condensed Consolidated Balance Sheets. Commissions payable at December 31, 2020 were $25.6 million, of which the current portion of $23.3 million was included in Accrued expenses and other current liabilities in our Condensed Consolidated Balance Sheets, and the long-term portion of $2.3 million was included in Other long-term liabilities in our Condensed Consolidated Balance Sheets. Certain commissions are not capitalized as they do not represent incremental costs of obtaining a contract. Such commissions are expensed as incurred. Unearned Revenue Unearned revenue consists of customer payments and billings in advance of revenue being recognized from our subscription services. Unearned revenue that is anticipated to be recognized within the next 12 months is recorded as Unearned revenue, current portion and the remaining portion is included in Unearned revenue, net of current portion in our Condensed Consolidated Balance Sheets.
Cash and Cash Equivalents	Cash equivalents consist of highly liquid marketable debt securities with remaining maturities of three months or less at the date of purchase.
Short-term Investments	We classify our investments in marketable securities as “available-for-sale.” We carry these investments at fair value, based on quoted market prices or other readily available market information. Unrealized gains and losses, net of taxes, are included in accumulated other comprehensive income, which is reflected as a separate component of stockholders’ equity in our Condensed Consolidated Balance Sheets. Gains and losses are determined using the specific identification method and recognized when realized in our Consolidated Statements of Operations. If we were to determine that an other-than-temporary decline in fair value has occurred, the amount of the decline related to a credit loss will be recognized in income.
Fair Value Measurements	Fair Value Measurements The Company measures assets and liabilities at fair value based on an expected exit price, which represents the amount that would be received on the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value may be based on assumptions that market participants would use in pricing an asset or liability. The authoritative guidance on fair value measurements establishes a consistent framework for measuring fair value on either a recurring or nonrecurring basis whereby inputs, used in valuation techniques, are assigned a hierarchical level. The following are the hierarchical levels of inputs to measure fair value: Level 1 - Observable inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities Level 2 - Other inputs that are directly or indirectly observable in the marketplace Level 3 - Unobservable inputs that are supported by little or no market activity, including the Company’s own assumptions in determining fair value The inputs or methodology used for valuing financial assets and liabilities are not necessarily an indication of the risk associated with investing in them.
Concentrations of Credit Risk and Significant Customers	Concentrations of Credit Risk and Significant CustomersFinancial instruments that potentially subject us to concentrations of credit risk consist principally of cash and cash equivalents, short-term investments, and accounts receivable. The Company holds cash at major financial institutions that often exceed Federal Deposit Insurance Corporation (“FDIC”) insured limits. The Company manages its credit risk associated with cash concentrations by concentrating its cash deposits in high-quality financial institutions and by periodically evaluating the credit quality of the primary financial institutions holding such deposits. The carrying value of cash approximates fair value. Our investment portfolio is comprised of highly rated securities with a weighted-average maturity of less than 12 months in accordance with our investment policy which seeks to preserve principal and maintain a high degree of liquidity. Historically, the Company has not experienced any losses due to such cash concentrations. The Company does not have any off-balance-sheet credit exposure related to its customers. Concentrations of credit risk with respect to accounts receivable and revenue are limited due to a large, diverse customer base. We do not require collateral from clients. We maintain an allowance for doubtful accounts based upon the expected collectability of accounts receivable. The Company performs ongoing credit evaluations of its customers and maintains allowances for possible losses, which, when realized, have been within the range of management’s expectations.
Accounts Receivable and Contract Assets	Accounts Receivable and Contract Assets Accounts receivable is comprised of invoices of revenue, net of allowance for doubtful accounts and does not bear interest. We consider receivables past due based on the contractual payment terms. Management’s evaluation of the adequacy of the allowance for doubtful accounts considers historical collection experience, changes in customer payment profiles, the aging of receivable balances, as well as current economic conditions, all of which may impact a customer’s ability to pay. Account balances are written-off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have significant bad debt experience with customers, and therefore, the allowance for doubtful accounts is immaterial as of March 31, 2021 and December 31, 2020. The assessment of variable consideration to be constrained is based on estimates, and actual consideration may vary from current estimates. As adjustments to these estimates become necessary, they are reported in earnings in the periods in which they become known. Changes in variable consideration are recorded as a component of net revenue. Contract assets represent a contractual right to consideration in the future. Contract assets are generated when contractual billing schedules differ from revenue recognition timing.
Property and Equipment, Net	Property and Equipment, NetProperty and equipment is stated at cost, net of accumulated depreciation and amortization. All repairs and maintenance costs are expensed as incurred. Depreciation and amortization costs are expensed on a straight-line basis over the lesser of the estimated useful life of the asset or the remainder of the lease term for leasehold improvements. Qualifying internal use software costs incurred during the application development stage, which consist primarily of internal product development costs, outside services, and purchased software license costs, are capitalized and amortized over the estimated useful life of the asset. Estimated useful lives range from 3 years to 10 years.
Advertising and Promotional Expenses	Advertising and Promotional ExpensesThe Company expenses advertising costs as incurred.
Research and Development	Research and Development Research and development expenses consist primarily of compensation expense for our employees, including employee benefits, certain IT program expenses, facilities and related overhead costs. We continue to focus our research and development efforts on developing new products, adding new features and services, integrating acquired technologies, and increasing functionality. Expenditures for software developed or obtained for internal use are capitalized and amortized over a four-year period on a straight-line basis.
Restructuring and Transaction-Related Expenses	Restructuring and Transaction-Related Expenses The Company defines restructuring and transaction related expenses as costs directly associated with acquisition or disposal activities. Such costs include employee severance and termination benefits, contract termination fees and penalties, and other exit or disposal costs. In general, the Company records involuntary employee-related exit and disposal costs when there is a substantive plan for employee severance and related costs that are probable and estimable. For one-time termination benefits for key members of management (i.e., no substantive plan), transaction related bonuses and employee retention costs, expense is recorded when the employees are entitled to receive such benefits and the amount can be reasonably estimated. Contract termination fees and penalties and other exit and disposal costs are generally recorded when incurred.
Business Combinations	Business Combinations We allocate purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values. The purchase price is determined based on the fair value of the assets transferred, liabilities assumed and equity interests issued, after considering any transactions that are separate from the business combination. The fair value of equity issued as part of a business combination is determined based on grant date stock price of the Company. The excess of fair value of purchase consideration over the fair values of the identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets and contingent liabilities. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired customer bases, acquired technology and acquired trade names, useful lives, royalty rates, and discount rates. The estimates are inherently uncertain and subject to revision as additional information is obtained during the measurement period for an acquisition, which may last up to one year from the acquisition date. During the measurement period, we may record adjustments to the fair value of tangible and intangible assets acquired and liabilities assumed, with a corresponding offset to goodwill. After the conclusion of the measurement period or the final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to earnings. In addition, uncertain tax positions and tax-related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. We reevaluate these items based upon the facts and circumstances that existed as of the acquisition date, with any revisions to our preliminary estimates being recorded to goodwill, provided that the timing is within the measurement period. Subsequent to the measurement period, changes to uncertain tax positions and tax-related valuation allowances will be recorded to earnings.
Goodwill and Acquired Intangible Assets	Goodwill and Acquired Intangible Assets Goodwill is calculated as the excess of the purchase consideration paid in a business combination over the fair value of the assets acquired less liabilities assumed. Goodwill is not amortized and is tested for impairment at least annually or when events and circumstances indicate that fair value of a reporting unit may be below its carrying value. The company has one reporting unit. We first assess qualitative factors to evaluate whether it is more likely than not that the fair value of a reporting unit is less than the carrying amount or elect to bypass such assessment. If it is determined that it is more likely than not that the fair value of the reporting unit is less than its carrying value, or we elect to bypass the qualitative assessment, we perform a quantitative test by determining the fair value of the reporting unit. If the carrying value of the reporting unit exceeds the fair value, then an impairment loss is recognized for the difference. Acquired technology, customer lists, trade names or brand portfolios, and other intangible assets are related to previous acquisitions (see Note 7). Acquired intangible assets are amortized on a straight-line basis over the estimated period over which we expect to realize economic value related to the intangible asset. The amortization periods range from 2 years to 15 years. Any costs incurred to renew or extend the life of an intangible or long-lived asset are reviewed for capitalization. Indefinite-lived intangible assets consist primarily of brand portfolios acquired from Pre-Acquisition ZI and represent costs paid to legally register phrases and graphic designs that identify and distinguish products sold by the Company. Brand portfolios are not amortized, rather potential impairment is considered on an annual basis in the fourth quarter, or more frequently upon the occurrence of a triggering event, when circumstances indicate that the book value of trademarks are greater than their fair value. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than the carrying value as a basis to determine whether further impairment testing is necessary.
Impairment of Long-lived Assets	Impairment of Long-lived Assets Long-lived assets, such as property and equipment and acquired intangible assets, are reviewed for impairment whenever events or circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the undiscounted future cash flows expected to be generated by the asset or group of assets. If the carrying amount of the asset exceeds the estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the estimated future cash flows of the asset.
Leases	Leases We determine if an arrangement is or contains a lease at contract inception. Determining if a contract contains a lease requires judgement. In certain of our lease arrangements, primarily those related to our data center arrangements, judgment is required in determining if a contract contains a lease. For these arrangements, there is judgment in evaluating if the arrangement involves an identified asset that is physically distinct or whether we have the right to substantially all of the capacity of an identified asset that is not physically distinct. In arrangements that involve an identified asset, there is also judgment in evaluating if we have the right to direct the use of that asset. We do not have any finance leases. Operating leases are recorded in our Condensed Consolidated Balance Sheets. Right-of-use assets and lease liabilities are measured at the lease commencement date based on the present value of the fixed minimum remaining lease payments over the lease term, determined using the discount rate for the lease at the commencement date. Because the rate implicit in our leases is not readily determinable, we use our incremental borrowing rate as the discount rate, which approximates the interest rate at which we could borrow on a collateralized basis with similar terms and payments and in similar economic environments. Some leases include options to extend or options to terminate the lease prior to the stated lease expiration. Optional periods to extend a lease, including by not exercising a termination option, are included in the lease term when it is reasonably certain that the option will be exercised (or not exercised in the case of termination options). Operating lease expense is recognized on a straight-line basis over the lease term. We account for lease and non-lease components, principally common area maintenance for our facilities leases, as a single lease component. Short term leases, defined as leases having an original lease term less than or equal to one year, are excluded from our right-of-use assets and liabilities.
Debt Issuance Costs	Debt Issuance Costs Costs incurred in connection with the issuance of long-term debt are deferred and amortized as interest expense over the terms of the related debt using the effective interest method for term debt and on a straight-line basis for revolving debt. To the extent that the debt is outstanding, these amounts are reflected in the consolidated balance sheets as direct deductions from a combination of current and long-term portions of debt. Upon a refinancing or amendment, previously-capitalized debt issuance costs are expensed and included in loss on extinguishment of debt, if the Company determines that there has been a substantial modification of the related debt. If the Company determines that there has not been a substantial modification of the related debt, any previously-capitalized debt issuance costs are amortized as interest expense over the term of the new debt instrument. The company performs assessments of debt modifications at a lender-specific level for all syndicated financing arrangements.
Tax Receivable Agreements	Tax Receivable Agreements In connection with our IPO, we entered into two Tax Receivable Agreements ("TRAs") with certain non-controlling interest owners (the “TRA Holders”). The TRAs generally provide for payment by the Company to the TRA Holders of 85% of the net cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the Company actually realizes or is deemed to realize in certain circumstances. The Company will retain the benefit of the remaining 15% of these net cash savings. Amounts payable under the TRA are accrued by a charge to income when it is probable that a liability has been incurred and the amount is estimable. TRA related liabilities are classified as current or noncurrent based on the expected date of payment and are included in the Company’s Condensed Consolidated Balance Sheets under the captions Current portion of tax receivable agreements liability and Tax receivable agreements liability, net of current portion, respectively. Subsequent changes to the measurement of the TRA liability are recognized in the statements of income as a component of other income (expense), net.
Income Taxes	Income Taxes ZoomInfo Technologies Inc. is a corporation and is subject to U.S. federal as well as state income tax related to its ownership percentage in ZoomInfo Holdings LLC. ZoomInfo Holdings LLC is a limited liability company treated as a partnership for U.S. federal income tax purposes and files a U.S. Return of Partnership Income. Consequently, the members of ZoomInfo Holdings are taxed individually on their share of earnings for U.S. federal and state income tax purposes. However, ZoomInfo Holdings is subject to the Texas Margins Tax. Additionally, our operations in Israel are subject to local country income taxes. See Note 17 for additional information regarding income taxes. Deferred taxes are recorded using the asset and liability method, whereby tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. We regularly evaluate the valuation allowances established for deferred tax assets for which future realization is uncertain. In assessing the realizability of deferred tax assets, we consider both positive and negative evidence, including scheduled reversals of deferred tax assets and liabilities, projected future taxable income, tax planning strategies and results of recent operations. If, based on the weight of available evidence, it is more likely than not that the deferred tax assets will not be realized, a valuation allowance is recorded.
Equity-Based Compensation Expense	Equity-Based Compensation Expense The Company periodically grants incentive units to employees and non-employees, which generally vest over a four-year period. Incentive units may be in the form of various equity-based awards such as restricted stock and restricted stock units, Class A stock options, and awards in one of the Company’s subsidiary partnerships which are typically in the form of profits interests. Profits interests are an interest in the increase in the value of the entity over a participation threshold. Prior to the IPO, the participation threshold was based on the valuation determined by the Board of Managers of OpCo Units on or around the grant date. Subsequent to the IPO, the participation threshold is determined by reference to the closing price of our Class A Common Stock from the preceding trading day. The holders of profits interests have the right to participate in distributions of profits only in excess of the participation threshold. Compensation expense for incentive units is measured at the estimated fair value of the incentive units and is included as compensation expense over the vesting period during which an employee provides service in exchange for the award. The Company uses a Black-Scholes option pricing model to determine the fair value of stock options and profits interests, as profits interests have certain economic similarities to options. The Black-Scholes option pricing model includes various assumptions, including the expected life of incentive units, the expected volatility and the expected risk-free interest rate. These assumptions reflect the Company’s best estimates, but they involve inherent uncertainties based on market conditions generally outside the control of the Company. As a result, if other assumptions are used, compensation cost could be materially impacted. The Company measures employee, non-employee, and board of director equity-based compensation on the grant date fair value basis. Equity-based compensation expense is recognized over the requisite service period of the awards. For equity awards that have a performance condition, the Company recognizes compensation expense based on its assessment of the probability that the performance condition will be achieved. The Company classifies equity-based compensation expense in its Consolidated Statements of Operations in the same manner in which the award recipient’s salary and related costs are classified or in which the award recipient’s service payments are classified.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recent Accounting Pronouncements Not Yet Adopted In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, which provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued because of reference rate reform, if certain criteria are met. The standard applies to contract modifications that replace a reference rate affected by reference rate reform and contemporaneous modifications of other contract terms related to the replacement of the reference rate. Further, the standard provides exceptions to certain guidance in ASC 815, Derivatives and Hedging, related to changes to the critical terms of a hedging relationship due to reference rate reform and provides optional expedients for fair value, cash flow, and net investment hedging relationships for which the component excluded from the assessment of hedge effectiveness is affected by reference rate reform. The standard is effective for us as of March 12, 2020 through December 31, 2022, and we may elect to apply the provisions of the standard as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020 up to the date that the financial statements are available to be issued. Once elected, the provisions of the standard must be applied prospectively for all similar eligible contract modifications other than derivatives, which may be applied at a hedging relationship level. The standard would apply to our existing variable rate financing and derivatives designated as hedges if elected in the future. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. It also eliminates the concept of other-than-temporary impairment and requires credit losses related to available-for-sale debt securities to be recorded through an allowance for credit losses rather than as a reduction in the amortized cost basis of the securities. These changes will result in more timely recognition of credit losses. The guidance is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Company adopted ASU 2016-13 and ASU 2019-05 effective January 1, 2020. The adoption of this guidance was on a modified retrospective basis and did not have a material impact on the Company's consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), which amends disclosure requirements for fair value measurements by requiring new disclosures, modifying existing requirements, and eliminating others. The amendments are the result of a broader disclosure project, which aims to improve the effectiveness of disclosures. ASU No. 2018-13 is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The Company adopted ASU 2018-13 on January 1, 2020, and the adoption did not have a material effect on the Company’s financial statements or disclosures.
