Summary of Significant Accounting Policies | Note 2. Summary of Significant Accounting Policies Fair Value of Financial Instruments — Certain financial assets and liabilities are reported at fair value in the accompanying consolidated balance sheets in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 820, Fair Value Measurement . ASC 820 establishes a framework for measuring fair value and expands disclosures about fair value measurements. ASC 820 defines fair value as the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The valuation techniques required by ASC 820 are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy: Level 1 — Quoted prices for identical instruments in active markets. Level 2 — Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 — Significant inputs to the valuation model are unobservable (supported by little or no market activities). These inputs may be used with internally developed methodologies that reflect the Company’s best estimate of fair value from a market participant. The carrying amounts of cash and cash equivalents, receivables, and accounts payable approximate fair value due to the short-term maturities of these financial instruments (Level 1). The fair values and carrying values of the Company’s long-term debt are disclosed in Note 7, “Debt”. The following table presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis and their assigned levels within the valuation hierarchy as of December 31, 2024 (in thousands): Level 1 Level 2 Level 3 Assets Interest rate swaps $ — $ 3,110 $ — Liabilities Interest rate swaps $ — $ 247 $ — Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Other intangible assets are subject to nonrecurring fair value measurement as the result of business acquisitions. The fair values of these assets were estimated using the present value of expected future cash flows through unobservable inputs (Level 3). Cash and Cash Equivalents — The Company considers cash equivalents to be cash and all short-term investments that have an original maturity of ninety days or less. Interest income earned on short-term investments and interest bearing accounts is included in interest expense, net in the accompanying consolidated statements of operations and comprehensive (loss) income. The Company recorded $ 9.6 million , $ 13.4 million , and $ 5.0 million of interest income for the years ended December 31, 2024, 2023, and 2022, respectively. Outstanding checks in excess of funds on deposit are classified as current liabilities in the accompanying consolidated balance sheets. As of December 31, 2024 and 2023 , the Company had no outstanding checks in excess of funds on deposit. Accounts Receivable — Accounts receivable are due from customers in a broad range of industries located throughout the United States and internationally. Credit is extended based on evaluation of the customer’s financial condition, and generally, collateral is not required. The allowance for all uncollectible receivables is based on a combination of historical data, cash payment trends, specific customer issues, write-off trends, general economic conditions, and other factors. These factors are continuously monitored by management to arrive at the estimate for the amount of accounts receivable that may be ultimately uncollectible. In circumstances where the Company is aware of a specific customer’s inability to meet its financial obligations, the Company records a specific allowance for doubtful accounts against amounts due in order to reduce the net recognized receivable to the amount it reasonably believes will be collected. The Company believes that the allowance for doubtful accounts at December 31, 2024 and 2023 is reasonably stated. Property and Equipment — Property and equipment are recorded at cost. Property and equipment include computer software for internal uses either developed internally, acquired by business combination or otherwise purchased. Software development costs, including internal personnel and third-party professional services, are capitalized during the application development stage of initial development or during development of new features and enhancements. Amortization commences when the software is placed into service and is computed using the straight-line method over the useful lives of the underlying software of three to five years . This is based on the historical observed pace of change in the Company’s delivery, technology, and product offerings as well as market competition. The Company amortizes purchased software using the straight-line method over the estimated useful life of three to five years and incremental software acquired by business combination on an accelerated basis over its expected useful life of five years . Software development costs not meeting the criteria for capitalization are expensed as incurred. Depreciation on leasehold improvements is computed on the straight-line method over the shorter of the life of the asset , or the lease term, ranging from one to fifteen years . Depreciation on data processing equipment and furniture and equipment is computed using the straight-line method over their estimated useful lives ranging from three to ten years . Business Combinations — The Company records business combinations using the acquisition method of accounting in accordance with ASC 805, Business Combinations . Under the acquisition method of accounting, identifiable assets acquired and liabilities assumed are recorded at their acquisition-date fair values. The excess of the purchase price over the estimated fair value is recorded as goodwill. Changes in the estimated fair values of net assets recorded for acquisitions prior to the finalization of more detailed analysis, but not to exceed one year from the date of acquisition, will adjust the amount of the purchase price allocable to goodwill. Measurement period adjustments are reflected in the period in which they occur. In valuing the trade names, customer lists, and software developed for internal use, the Company utilizes variations of the income approach, which relies on historical financial and qualitative information, as well as assumptions and estimates for projected financial information. The Company considers the income approach the most appropriate valuation technique because the inherent value of these assets is their ability to generate current and future income. Projected financial information is subject to risk if estimates are incorrect. The most significant estimate relates to projected revenues and profitability. If the projected revenues and profitability used in the valuation calculations are not met, then the asset could be impaired . Goodwill, Trade Names, Customer Lists, and Other Intangible Assets — The Company tests goodwill for impairment annually as of October 31 or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit or indefinite-lived intangible asset below its carrying value. During 2023, the Company changed its annual impairment testing date from December 31 to October 31. The Company believes the new date is preferable because it aligns the impairment test with the budgeting processes. The Company applied the change in accounting principle prospectively. The change in the annual impairment testing date did not delay, accelerate, or avoid an impairment charge. Goodwill is tested for impairment at the reporting unit level using a fair value approach. At October 31, 2024, the Company had three reporting units comprised of First Advantage Americas, First Advantage International, and Sterling. When testing goodwill for impairment, the Company may first perform an optional qualitative assessment. If the Company determines it is not more likely than not the reporting unit’s fair value is less than its carrying value, then no further analysis is necessary. If the Company determines that it is more likely than not that the fair value of its reporting unit is less than its carrying amount, then the quantitative impairment test will be performed. Under the quantitative impairment test, if the carrying amount of the Company’s reporting unit exceeds its fair value, the Company will recognize an impairment loss in an amount equal to that excess but limited to the total amount of goodwill. The Company performs a quantitative impairment test every three years, irrespective of the outcome of the Company’s qualitative assessment. No impairment charges have been required. The Company’s trade names are amortized on an accelerated basis over their expected useful lives ranging from five to twenty years . The Company recorded $ 9.3 million , $ 7.3 million , and $ 7.6 million of amortization expense related to trade names for the years ended December 31, 2024, 2023, and 2022, respectively. Customer lists are amortized on an accelerated basis based upon their estimated useful lives, ranging from thirteen to fourteen years. The Company recorded $ 58.9 million , $ 54.6 million , and $ 60.7 million of amortization expense related to customer lists for the years ended December 31, 2024, 2023, and 2022, respectively. The Company’s other intangible assets are amortized on a straight-line or accelerated basis over their expected useful life of five year s. The Company recorded $ 0.5 million and $ 0.1 million of amortization expense related to other intangible assets for the year ended December 31, 2024 and 2023 , respectively. No amortization expense was recorded for the year ended December 31, 2022. The Company regularly evaluates the amortization period assigned to each intangible asset to determine whether there have been any events or circumstances that warrant revised estimates of useful lives. No impairment charges have been required. Income Taxes — The Company is a U.S. domiciled corporation for tax purposes. Accordingly, the Company has followed ASC 740, Income Taxes , which provides for income taxes using the liability method, which requires an asset and liability based approach in accounting for income taxes for all periods presented. Deferred income taxes reflect the net tax effect on future years of temporary differences in the carrying amount of assets and liabilities between financial statements and income tax purposes. Valuation allowances are established when the Company determines that it is more likely than not that some portion or the entire deferred tax asset will not be realized. The Company evaluates its effective tax rates regularly and adjusts them when appropriate based on currently available information relative to statutory rates, apportionment factors and the applicable taxable income in the jurisdictions in which the Company operates, among other factors. The Company calculates additional tax provisions, where applicable, related to accounting for uncertainty in income taxes, which prescribe a recognition threshold and measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The amount recognized is measured as the largest benefit that has a greater than 50% likelihood of being realized upon settlement. The Company adjusts its estimates of uncertain tax positions periodically because of ongoing examinations by, and settlements with, various taxing authorities, as well as changes in tax laws, regulations, and interpretations. The Company classifies interest and penalties associated with its unrecognized tax benefits as a component of income tax expense (see Note 9. “Income Taxes”). Impairment of Long-Lived Assets — The Company regularly evaluates whether events and circumstances have occurred that indicate the carrying amount of property and equipment, ROU assets, and finite-life intangible assets may not be recoverable. Conditions that could indicate an impairment assessment is needed include a significant decline in the observable market value of an asset or asset group, a significant change in the extent or manner in which an asset or asset group is used, or a significant adverse change that would indicate that the carrying amount of an asset or asset group is not recoverable. When factors indicate that these long-lived assets or asset groups should be evaluated for possible impairment, the Company assesses the potential impairment by determining whether the carrying value of such long-lived assets or asset groups will be recovered through the future undiscounted cash flows expected from use of the asset or asset group and its eventual disposition. If the carrying amount of the asset or asset group is determined not to be recoverable, an impairment charge is recorded based on the excess, if any, of the carrying amount over fair value. Fair values are determined based on quoted market values or discounted cash flows analyses as applicable. The Company regularly evaluates whether events and circumstances have occurred that indicate the useful lives of property and equipment, right of use (“ROU”) assets, and finite-life intangible assets may warrant revision. No material impairment charges have been required for the years ended December 31, 2024, 2023 and 2022. Leases — The Company accounts for leases in accordance with ASC 842, Leases . The Company measures ROU assets and liabilities based on the present value of the future minimum lease payments over the lease term at the commencement date. Minimum lease payments include the fixed lease and non-lease components of the agreement, as well as any variable rent payments that depend on an index, initially measured using the index at the lease commencement date. ROU assets are adjusted for any initial direct costs incurred less any lease incentives received, in addition to payments made on or before the commencement date of the lease. The Company recognizes lease expense for leases on a straight-line basis over the lease term. As the implicit rate is not readily determinable for most of the Company’s lease agreements, the Company uses its estimated incremental borrowing rate to determine the initial present value of lease payments. The Company determines if a contract is or contains a lease at inception. The Company has operating and finance leases for office space, data centers, and equipment. Leases with an initial term of 12 months or less are not recorded on the balance sheet. The Company enters into lease contracts ranging from 1 to 8 years. Some leases include one or more options to renew, with renewal terms that can extend the lease term from 1 to 5 years or more. The exercise of these lease renewal options is at the Company’s sole discretion and typically are not reasonably certain to renew at inception. The depreciable life of assets and leasehold improvements are limited by the expected lease term. Advertising Costs — Advertising costs are expensed as incurred and are included in selling, general and administrative expense in the accompanying consolidated statements of operations and comprehensive (loss) income. Advertising costs were $ 2.9 million , $ 1.9 million , and $ 2.9 million for the years ended December 31, 2024, 2023, and 2022 , respectively. Derivative Instruments — The Company is exposed to certain risks relating to its ongoing business operations and mitigates interest rate risk through the use of derivative instruments. Interest rate swaps have been entered into to manage a portion of the interest rate risk associated with the Company’s variable-rate borrowings. In accordance with ASC 815, Derivatives and Hedging , the derivative instruments are recognized and subsequently measured on the balance sheet at fair value. The Company reviewed its interest rate swaps and determined they do not meet the definition of cash flow hedges. Therefore, the guidance requires that the change in fair value of the interest rate swaps be recognized as a component of income or expense in the consolidated statements of operations and comprehensive (loss) income (see Note 8. “Derivatives”). Concentrations of Credit Risk — Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents and accounts receivable. Cash is deposited with major financial institutions and, at times, such balances with each financial institution may be in excess of insured limits. The Company has not experienced, and does not anticipate, any losses with respect to its cash deposits. Accounts receivable represent credit granted to customers for services provided. The Company performs ongoing credit evaluations of its customers’ financial condition and generally does not require collateral on accounts receivable. The Company had one customer which represented approximately 12 % , 12 %, and 10 % of its consolidated revenues for the years ended December 31, 2024, 2023, and 2022 , respectively, in its First Advantage Americas segment. No other customer represented 10 % or more of its revenue for these periods. The Company had one customer which represented approximately 17 %, of its consolidated accounts receivable, net as of December 31, 2023 . No other customers represented 10 % or more of its consolidated accounts receivable, net for any period presented. The Company has entered into interest rate derivative agreements with a counterparty bank to reduce its exposure to interest rate volatility. The Company has determined the counterparty bank to be a high credit quality institution. The Company does not enter into financial instruments for trading or speculative purposes. Revenue Recognition — Revenues are recognized when control of the Company’s services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. In accordance with ASC 606, Revenue from Contracts with Customers revenues are recognized based on the following steps: a) Identify the contract with a customer b) Identify the performance obligations in the contract c) Determine the transaction price d) Allocate the transaction price to the performance obligations in the contract e) Recognize revenue when (or as) the entity satisfies a performance obligation A substantial majority of the Company’s revenues are derived from pre-onboarding and related services to our customers on a transactional basis, in which an individual background screening package or selection of services is ordered by a customer related to a single individual. Substantially all of the Company’s customers are employers, staffing companies, and other businesses or organizations. The Company’s revenues are mostly comprised of a significant volume of low-dollar services fulfilled by multiple highly automated, proprietary systems and applications. The processing of transactions and recording of revenue is based on contractual terms with the Company’s customers. The Company satisfies its performance obligations and recognizes revenues for services rendered as the orders are completed and the completed reports are transmitted, or otherwise made available. The Company’s remaining services, substantially consisting of tax consulting, fleet management, and driver qualification services, are delivered over time as the customer simultaneously receives and consumes the benefits of the services delivered. To measure the Company’s performance over time, the output method is utilized to measure the value to the customer based on the transfer to date of the services promised, with no rights of return once consumed. In these cases, revenues on transactional contracts with a defined price but an undefined quantity are recognized utilizing the right to invoice expedient resulting in revenues being recognized when the service is provided and becomes billable. Additionally, under this practical expedient, the Company is not required to estimate the transaction price. For revenue arrangements containing multiple services, the Company accounts for the individual service as separate performance obligations if they are distinct, the service is separately identifiable from other terms in the contract, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. If these criteria are not met, the promised services are accounted for as a combined performance obligation. The Company allocates the contract price to each performance obligation based on the standalone selling prices of each distinct product or service in the contract. The Company considers negotiated and anticipated incentives and estimated adjustments, including historical collections experience, when recording revenues. The Company’s contracts with customers generally include standard commercial payment terms acceptable in each region, and do not include any financing components. The Company does not have any significant obligations for refunds, warranties, or similar obligations. The Company records revenues net of sales taxes. Due to the Company’s contract terms and the nature of the background screening industry, the Company determined its contract terms for ASC 606 purposes are generally one year or less, but can extend up to three years in limited circumstances. Incremental costs of obtaining a contract with a customer are recognized as an asset if the benefit of such costs is expected to be longer than one year. Beginning in 2024, incremental costs primarily consist of sales commissions and are amortized over three years, for certain contracts, as management estimates that this corresponds to the period over which a customer benefits from the contract. Deferred commissions as of December 31, 2024 were immaterial and included in prepaid expenses and other current assets and other assets in the accompanying consolidated balance sheets. The Company records third-party pass-through fees incurred as part of screening related services on a gross revenue basis, with the related expense recorded as a cost of services expense, as the Company has control over the transaction and is therefore considered to be acting as a principal. The Company records motor vehicle registration and other tax payments paid on behalf of the Company’s fleet management customers on a net revenue basis as the Company does not have control over the transaction and therefore, is considered to be acting as an agent of the customer. Amounts received from fleet management customers are recorded in cash and cash equivalents in the accompanying consolidated balance sheets as the funds are not legally restricted. Contract balances are generated when the revenues recognized in a given period varies from billing. A contract asset is created when the Company performs a service for a customer and recognizes more revenues than what has been billed. The Company recognizes these contract assets as accounts receivable, in the accompanying consolidated balance sheets, when a conditional right to consideration exists and transfer of control has occurred. A contract liability is created when the Company transfers a good or service to a customer and recognizes less than what has been billed. The Company recognizes these contract liabilities as deferred revenues, in the accompanying consolidated balance sheets, when the Company has an obligation to perform services for a customer in the future and has already received consideration from the customer. Foreign Currency — The functional currency of all of the Company’s foreign subsidiaries is the applicable local currency. The translation of the applicable foreign currencies into U.S. dollars is performed for balance sheet accounts using current exchange rates in effect at the balance sheet date and for revenues and expense accounts using average exchange rates prevailing during the fiscal year. Adjustments resulting from the translation of foreign currency financial statements are accumulated net of tax in a separate component of equity. Currency translation (loss) income included in accumulated other comprehensive (loss) income were approximately $( 16.2 ) million , $ 1.2 million , and $( 20.7 ) million , for the years ended December 31, 2024, 2023, and 2022, respectively. Gains or losses resulting from foreign currency transactions are included in the accompanying consolidated statements of operations and comprehensive (loss) income, except for those relating to intercompany transactions of a long-term investment nature, which are captured in a separate component of equity as accumulated other comprehensive income (loss). Currency transaction income (loss) included in the accompanying consolidated statements of operations and comprehensive (loss) income was approximately $ 0.4 million , $( 0.1 ) million , and $ 2.3 million , for the years ended December 31, 2024, 2023, and 2022 , respectively. Share-based Compensation — Prior to the Company’s Initial Public Offering (“IPO”), all share-based awards were issued by a parent of the Company under individual grant agreements and the partnership agreement (collectively the “2020 Equity Plan”). Following the IPO, share-based awards are issued to employees and non-employee directors under the 2021 Omnibus Incentive Plan (as amended by the First Amendment, dated as of May 10, 2023, the “2021 Equity Plan”). Both plans were designed with the intention of promoting the long-term success of the Company by attracting, motivating, and retaining key employees of the Company. Additionally, as discussed in Note 1. “Organization, Nature of Business, and Basis of Presentation”, the Company completed its cash-and-stock acquisition of Sterling on October 31, 2024. As part of the acquisition, certain outstanding equity awards held by Sterling employees were converted into equity awards of the Company (“Sterling Acquisition Awards”). The Company accounts for awards issued in accordance with ASC 718, Compensation — Stock Compensation . Management expects to allow its employees granted awards under all plans to bear the risks and rewards normally associated with equity ownership for a reasonable period of time when all requisite vesting requirements have been rendered. No outstanding awards are callable, and therefore, the related share-based awards are classified as equity. The calculation of share-based employee compensation expense involves estimates that require management’s judgment. These estimates include the fair value of each of the share-based awards granted, which is estimated on the date of grant using a Black-Scholes option-pricing model. There are four inputs into the Black-Scholes option-pricing model: expected volatility, risk-free interest rates, expected term, and estimated fair value of the underlying unit. The Company estimates expected volatility based on an analysis of guidelines of publicly traded peer companies’ historical volatility. The risk-free interest rate is based on the treasury constant maturities rate based on data published by the U.S. Federal Reserve. The expected term of share-based awards granted is derived from historical exercise experience under the Company’s share-based plans and represents the period of time that awards granted are expected to be outstanding. Because of the limitations on the sale or transfer of our equity as a privately held company and a lack of historical option exercises as a public company, the Company does not believe our historical exercise pattern is indicative of the pattern we will experience in future periods. The Company has consequently used the simplified method to calculate the expected term, which is the average of the contractual term and vesting period, and plans to continue to use the simplified method until we have sufficient exercise and pricing history. Finally, prior to the IPO, the estimated fair value of the underlying equity was determined using either a transaction valuation or a blend of income and market approaches. After the IPO, the estimated fair value of the underlying equity was based on the observable market price of the Company’s equity. The assumptions used in calculating the fair value of share-based payment awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management’s judgment. As a result, if factors change and the Company uses different assumptions, share-based compensation expenses could be materially different in the future. In addition, for awards with a service condition, the Company has elected to account for forfeitures as they occur. Therefore, the Company will reverse compensation costs previously recognized when an unvested award is forfeited. For awards with a performance condition, the Company is required to estimate the expected forfeiture rate, and only recognize expenses for those shares expected to vest. The Company estimates the expected forfeiture rate based on the Company’s historical data, grant terms, and anticipated plan participant turnover. If the Company’s actual forfeiture rate is materially different from its estimate, the share-based compensation expense could be significantly different from what the Company has recorded in the current period. Comprehensive Income — Comprehensive income includes gains and losses from foreign currency translation adjustments, net. Net Income Per Share of Equity — Basic net income per share are computed by dividing net income by the weighted average number of common shares outstanding during the period. Basic weighted-average shares outstanding excludes nonvested restricted stock. Diluted net income per share is computed by dividing net income by the weighted average number of shares outstanding during the period after adjusting for the impact of securities that would have a dilutive effect on net income per share. Diluted weighted average shares outstanding, is similar to basic weighted-average shares outstanding, except that the weighted-average number of shares is increased to include the number of additional common shares that would have been outstanding if the potentially dilutive common share had been issued, including the dilutive impact of nonvested restricted stock. The Company uses the treasury stock method to incorporate potentially dilutive securities in diluted net income per share. The potentially dilutive securities outstanding during the year ended December 31, 2024 had an anti-dilutive effect and were therefore not included in the calculation of diluted net loss per share for the period. The potentially dilutive securities outstanding during the years ended December 31, 2023 and 2022 had a dilutive effect and were included in the calculation of diluted net income per share for the period. Recent Accounting Pronouncements —In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which requires a public business entity to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. The ASU also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions. This guidance is effective for fiscal years beginning after December 15, 2024, and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. The Company is currently evaluating the guidance and its impact to its consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (Subtopic 220-40) . The ASU requires the disaggregated disclosure of specific expense categories, including purchases of inventory, employee compensation, depreciation, and amortization included in each relevant expense caption presented on the statement of operations. The guidance also requires disclosure of a qualitat |
