Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP, and Securities and Exchange Commission, or SEC, requirements. The consolidated financial statements include the accounts of Q2 Holdings, Inc. and its direct and indirect wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses. Significant items subject to such estimates include: revenue recognition; estimate of credit losses; fair value of certain stock awards issued; the carrying value of goodwill; the fair value of acquired intangibles; the useful lives of property and equipment and long-lived intangible assets; the impairment assessment of long-lived assets; and, income taxes. In accordance with GAAP, management bases its estimates on historical experience and on various other assumptions that management believes are reasonable under the circumstances. Management regularly evaluates its estimates and assumptions using historical experience and other factors; however, actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all highly liquid investments acquired with an original maturity of ninety days or less at the date of purchase to be cash equivalents. Cash equivalents are stated at cost or fair value based on the underlying security. Restricted Cash Restricted cash consists of deposits held as collateral for the Company's secured letters of credit or bank guarantees issued in place of security deposits for the Company's corporate headquarters and various other leases and deposits that are restricted to withdrawal or use as of the reporting date under contractual terms with certain customer arrangements. Investments Investments typically include U.S. government securities, corporate bonds, commercial paper, certificates of deposit, money market funds and other equity investments. All debt investments are considered available for sale and are carried at fair value. Equity investments without a readily determinable fair value, where the Company has no influence over the operating and financial policies of the investee, are recorded at cost, less impairment and adjusted for subsequent observable price changes obtained from orderly transactions for identical or similar investments issued by the same investee. Adjustments resulting from impairment, fair value, or observable price changes are accounted for in the consolidated statements of comprehensive loss. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, restricted cash, investments, accounts receivable and contract assets. The Company's cash and cash equivalents, restricted cash and investments are placed with high credit quality financial institutions and issuers, and at times may exceed federally insured limits. The Company has not experienced any loss relating to cash and cash equivalents or restricted cash in these accounts. The Company provides credit, in the normal course of business, to a majority of its customers. The Company performs periodic credit evaluations of its customers' financial condition and generally does not require collateral. No individual customer accounted for 10% or more of revenues for each of the years ended December 31, 2023, 2022 and 2021. No individual customer accounted for 10% or more of accounts receivable, net, as of December 31, 2023 and two customers accounted for 12% and 10% of accounts receivable, net, as of December 31, 2022. Contract Assets and Deferred Revenue The timing of revenue recognition, billings and cash collections can result in billed accounts receivable, unbilled receivables, contract assets, and deferred revenues or contract liabilities. Billings scheduled to occur after the performance obligation has been satisfied and revenue recognition has occurred result in contract assets. Contract assets that are expected to be billed during the succeeding twelve-month period are recorded in contract assets, current portion, and the remaining portion is recorded in contract assets, net of current portion on the consolidated balance sheets at the end of each reporting period. Contract liabilities, or deferred revenues, primarily consist of amounts that have been billed to or received from customers in advance of revenue recognition and prepayments or deposits received from customers in advance for implementation, maintenance and other services, as well as subscription fees. Customer prepayments are generally applied against invoices issued to customers when services are performed and billed. The Company recognizes deferred revenues as revenues when the services are performed and the corresponding revenue recognition criteria are met. Customer prepayments are generally applied against invoices issued to customers when services are performed and billed. Contract liabilities that are expected to be recognized as revenues during the succeeding twelve-month period are recorded in deferred revenues, current portion, and the remaining portion is recorded in deferred revenues, net of current portion, on the consolidated balance sheets at the end of each reporting period. The Company's payment terms vary by the type and location of its customer and the products or services offered. The period of time between invoicing and when payment is due is not significant. For certain products or services and customer types, the Company requires payment before the products or services are delivered to the customer. Accounts Receivable Accounts receivable are stated at net realizable value, including both billed and unbilled receivables to customers. Unbilled receivable balances arise primarily when the Company provides services in advance of billing for those services. Generally, billing for revenues related to the number of End Users and the number of transactions processed by the customers' End Users that are included in the customers' minimum subscription fee occurs in the month the revenue is recognized, resulting in accounts receivable. Billing for revenues relating to the number of End Users and the number of transactions processed by the End Users that are in excess of the customers' minimum subscription fees are, generally, billed in the month following the month the revenues were earned, resulting in an unbilled receivable. Unbilled receivables of $7.4 million and $5.8 million were included in the accounts receivable balance as of December 31, 2023 and 2022, respectively. Deferred Implementation Costs The Company capitalizes certain personnel and other costs, such as employee salaries, stock-based compensation, benefits and the associated payroll taxes that are identifiable and directly related to the implementation of its solutions. The Company analyzes implementation costs that may be capitalized to assess their recoverability and only capitalizes costs that it anticipates being recoverable through the terms of the associated contract. The Company begins amortizing the deferred implementation costs for an implementation to cost of revenues once the revenue recognition criteria have been met, and the Company amortizes those deferred implementation costs ratably over the expected period of customer benefit. The Company has determined this period to be the estimated life of the technology for new contracts, which is estimated to be five to a competitor's product, all of which are governed by the estimated useful life of the technology. The Company monitors deferred implementation costs for impairment and records impairment when customers terminate or allow services to lapse due to contract modifications and/or from other assessments as needed. Any impairment losses identified are recognized in the form of an expense acceleration with the applicable amount recorded to deferred implementation costs, current portion and/or deferred implementation costs, net of current portion on the consolidated balance sheet and in cost of revenues in the consolidated statements of comprehensive loss. The portion of deferred implementation costs expected to be amortized during the succeeding twelve-month period is recorded in current assets as deferred implementation costs, current portion, and the remainder is recorded in long-term assets as deferred implementation costs, net of current portion on the consolidated balance sheets. The Company recognized $13.4 million, $11.5 million and $11.9 million of amortization during the years ended December 31, 2023, 2022 and 2021, respectively. Amortization expense is included in cost of revenues in the consolidated statements of comprehensive loss. Deferred Solution and Other Costs The Company capitalizes sales commissions and other third-party costs such as third-party licenses and maintenance related to its customer agreements. The Company capitalizes sales commissions because the commission payments are considered incremental and recoverable costs of obtaining a contract with a customer. The Company capitalizes commissions and related bonuses for those involved in the sale which are incremental to the sale and their associated management. Substantially all commissions are paid in a single payment once the contract has been executed and the initial deposit has been received from the customer. The Company begins amortizing deferred solution and other costs for a particular customer agreement once the revenue recognition criteria are met and amortizes those deferred costs over the expected period of customer benefit. The Company has determined this period to be the estimated life of the technology for new contracts, which is estimated to be five due to contract modifications and/or from other assessments as needed. Any impairment losses identified are recognized in the form of an expense acceleration with the applicable amount recorded to deferred solution and other costs, current portion and/or deferred solution and other costs, net of current portion on the consolidated balance sheet and in sales and marketing expenses in the consolidated statements of comprehensive loss. The Company capitalizes solution and other costs that it anticipates being recoverable. The portion of capitalized costs expected to be amortized during the succeeding twelve-month period is recorded in current assets as deferred solution and other costs, current portion, and the remainder is recorded in long-term assets as deferred solution and other costs, net of current portion. The Company recognized $12.5 million, $11.7 million and $12.6 million of amortization from sales commissions during the years ended December 31, 2023, 2022 and 2021 respectively. Amortization expense related to sales commissions is included in sales and marketing expenses in the consolidated statements of comprehensive loss. Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the related assets. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful lives of the related assets. Maintenance and repairs that do not extend the life of or improve an asset are expensed in the period incurred. The estimated useful lives of property and equipment are as follows: Computer hardware and equipment 3 - 5 years Purchased software and licenses 3 - 5 years Furniture and fixtures 7 years Leasehold improvements Lesser of estimated useful life or lease term Purchase Price Allocation, Intangible Assets, and Goodwill The purchase price allocation for business combinations and asset acquisitions requires extensive use of accounting estimates and judgments to allocate the purchase price to the identifiable tangible and intangible assets acquired and liabilities assumed based on their respective fair values. The Company determines whether substantially all the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the single asset or group of assets, as applicable, is not a business. If it is not met, the Company determines whether the single asset or group of assets, as applicable, meets the definition of a business. In connection with the Company's business combinations, the Company recorded certain intangible assets, including acquired technology, customer relationships, trademarks, and non-compete agreements. Amounts allocated to the acquired intangible assets are amortized on a straight-line basis over the estimated useful lives. The Company periodically reviews the estimated useful lives and fair values of its identifiable intangible assets, taking into consideration any events or circumstances which might result in a diminished fair value or revised useful life. The excess purchase price over the fair value of assets acquired is recorded as goodwill. The Company tests goodwill for impairment annually in October, or whenever events or changes in circumstances indicate an impairment may have occurred. Because the Company operates as a single reporting unit, the impairment test is performed at the consolidated entity level by comparing the estimated fair value of the Company to the carrying value of the Company. The Company estimates the fair value of the reporting unit using a "step one" analysis using a fair-value-based approach based on market capitalization to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount. Determining the fair value of goodwill is subjective in nature and often involves the use of estimates and assumptions including, without limitation, use of estimates of future prices and volumes for the Company's products, capital needs, economic trends and other factors which are inherently difficult to forecast. If actual results, or the plans and estimates used in future impairment analyses are lower than the original estimates used to assess the recoverability of these assets, the Company could incur impairment charges in a future period. Revenues Revenues are recognized when control of the promised goods or services is transferred to the Company's customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services over the term of the agreement, generally when the Company's solutions are implemented and made available to the customers. The promised consideration may include fixed amounts, variable amounts or both. Revenues are recognized net of sales credits and allowances. Revenue-generating activities are directly related to the sale, implementation and support of the Company's solutions within a single operating segment. The Company derives the majority of its revenues from subscription fees for the use of its solutions hosted in either the Company's data centers or with cloud-based service providers, transactional revenue from bill-pay solutions, revenues for professional services and implementation services related to the Company's solutions and certain third-party related pass-through fees. Subscription Revenues The Company's software solutions are available for use as hosted application arrangements under subscription fee agreements without licensing rights to the software. Subscription fees from these applications, including contractual periodic price increases, are recognized over time on a ratable basis over the customer agreement term beginning on the date the Company's solution is made available to the customer. Amounts that have been invoiced are recorded in accounts receivable and deferred revenues or revenues, depending on whether the revenue recognition criteria have been met. Periodic price increases are estimated at contract inception where appropriate and result in contract assets as revenue recognition may exceed the amount billed early in the contract. Additional fees for monthly usage above the levels included in the standard subscription fee are recognized as revenue in the month when the usage amounts are determined and reported. A small portion of the Company's customers host and manage the Company's solutions on-premises or in third-party data centers under term license and maintenance agreements. Term licenses sold with maintenance entitle the customer to technical support, upgrades and updates to the software on a when-and-if-available basis. The Company recognizes software license revenue once the customer obtains control of the license, which generally occurs at the start of each license term. The Company recognizes the remaining arrangement consideration for maintenance revenue over time on a ratable basis over the term of the software license. Revenues from term licenses and maintenance agreements were not significant in the periods presented. Transactional Revenues The Company generates a majority of its transactional revenues based on the number of bill-pay transactions that End Users initiate on its digital banking platform. The Company also generates a portion of its transactional revenues from third-party fees related to End Users utilizing remote deposit products and from fees generated when End Users utilize debit cards integrated with its Helix products. The Company recognizes revenue for transaction services in the month incurred based on actual or estimated transactions. Services and Other Revenues Implementation services are required for new digital banking and lending and other standalone contracts, and there is a significant level of integration and configuration for each customer. The Company's revenue for implementation services is billed upfront and generally recognized over time on a ratable basis over the customer's term for its hosted application agreements. Implementation services for on-premises agreements are recognized at commencement date. Under certain circumstances, the Company has determined that these implementation services qualify as a separate performance obligation in certain markets and geographies, and the implementation services for these agreements are recognized over time as services are performed. Professional services revenues consist primarily of Premier Services. Premier Services revenue is generated from select established customer relationships where the Company has engaged with the customer for more tailored, premium professional services, resulting in a deeper and ongoing level of engagement with them. Professional services revenues also consist of custom services, core conversion services and other general professional services. These revenues are generally billed and recognized when delivered. Other Revenues also include certain third-party related pass-through fees primarily in our Helix business that are not transactional in nature. Certain out-of-pocket expenses billed to customers are recorded as revenues rather than an offset to the related expense. Significant Judgments Performance Obligations and Standalone Selling Price A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of accounting. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may require significant judgment. The Company has contracts with customers that often include multiple performance obligations, usually including multiple subscription and implementation services. For these contracts, the Company accounts for individual performance obligations that are separately identifiable by allocating the contract's total transaction price to each performance obligation in an amount based on the relative standalone selling price, or SSP, of each distinct good or service in the contract. In determining whether implementation services are distinct from subscription services, the Company considered various factors including the significant level of integration, interdependency, and interrelation between the implementation and subscription service, as well as the inability of the customer's personnel or other service providers to perform significant portions of the services. The Company has concluded that the implementation services included in contracts with multiple performance obligations across the majority of its markets and product offerings are not distinct and, as a result, the Company defers any arrangement fees for implementation services and recognizes such amounts over time on a ratable basis as one performance obligation with the underlying subscription revenue for the initial agreement term of the hosted application agreements. The Company has concluded that for some of its products in certain markets the implementation services included in contracts with multiple performance obligations are distinct and, as a result, the Company recognizes implementation fees on such arrangements over time as services are performed. The majority of the Company's revenue recognized at a particular point in time is for usage revenue, on-premise software licenses and certain professional services. These services are recognized as the customer obtains control of the asset, as services are performed, or the point the customer obtained control of the software. Judgment is required to determine the SSP for each distinct performance obligation. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The Company determines SSP based on overall pricing objectives and strategies, taking into consideration entity-specific factors, including the value of our contracts, historical standalone sales, customer demographics and the numbers and types of users within our contracts. Variable Consideration The Company recognizes usage revenue related to End Users accessing its products in excess of contracted amounts and from fees that End Users generate using the Company's solutions. Judgment is required to determine the accounting for these types of revenue. The Company considers various factors including the degree to which usage is interdependent or interrelated to past services, costs to the Company per user over the contract, and contractual price per user changes and their relationship to market terms, forecasted data, and the Company's cost to fulfill the obligation. The Company has concluded that its usage revenue relates specifically to the transfer of the service to the customer and is consistent with the allocation objective of Topic 606 when considering all of the performance obligations and payment terms in the contract. Therefore, the Company recognizes usage revenue on a monthly or quarterly basis in accordance with the agreement, as determined and reported. This allocation reflects the amount the Company expects to receive for the services for the given period. The Company sometimes provides credits or incentives to its customers. Known and estimable credits and incentives represent a form of variable consideration, which are estimated at contract inception and generally result in reductions to revenues recognized for a particular contract. These estimates are updated at the end of each reporting period as additional information becomes available. The Company believes that there will not be significant changes to its estimates of variable consideration as of December 31, 2023. Other Considerations The Company evaluates whether it is the principal (i.e., reports revenues on a gross basis) or agent (i.e., reports revenues on a net basis) with respect to the vendor reseller agreements pursuant to which the Company resells certain third-party solutions along with the Company's solutions. Generally, the Company reports revenues from these types of contracts on a gross basis, meaning the amounts billed to customers are recorded as revenues, and expenses incurred are recorded as cost of revenues. Where the Company is the principal, it first obtains control of the inputs to the specific good or service and directs their use to create the combined output. The Company's control is evidenced by its involvement in the integration of the good or service on its platform before it is transferred to its customers and is further supported by the Company being primarily responsible to its customers and having a level of discretion in establishing pricing. Revenues provided from agreements in which the Company is an agent are insignificant. Cost of Revenues Cost of revenues is comprised primarily of salaries and other personnel-related costs, including employee benefits, bonuses and stock-based compensation, for employees providing services to the Company's customers. This includes the costs of the Company's personnel performing implementation, customer support, data center and customer training activities. Cost of revenues also includes the direct costs of bill-pay and other third-party intellectual property included in the Company's solutions, the amortization of deferred solution and services costs, amortization of certain software development costs, co-location facility costs and depreciation of the Company's data center assets, debit card related pass-through fees, cloud-based hosting services, an allocation of general overhead costs, the amortization of acquired technology intangibles and referral fees. The Company allocates general overhead expenses to all departments based on the number of employees in each department, which the Company considers to be a fair and representative means of allocation. The Company capitalizes certain personnel costs directly related to the implementation of its solutions to the extent those costs are recoverable from future revenues. The Company amortizes the costs for an implementation once revenue recognition commences, and the Company amortizes those implementation costs to cost of revenues over the expected period of customer benefit, which has been determined to be the estimated life of the technology. Other costs not directly recoverable from future revenues are expensed in the period incurred. The Company also amortizes the costs capitalized for software development, as described in the next section, to cost of revenues, when products and enhancements are released or made available over the products' estimated economic lives. Software Development Costs During the application development stage, the Company capitalizes certain development costs associated with internal use software and the Company's SaaS platform. Software development costs include salaries and other personnel-related costs for those employees who are directly associated with and who devote time to developing the Company's software solutions, including employee benefits, stock-based compensation and bonuses attributed to software engineers, quality control teams and third-party development costs. Capitalized software development costs are computed on an individual product basis. The Company also capitalizes certain costs related to specific enhancements when it is probable the expenditures will result in additional features and functionality. Capitalization ceases for products and enhancements when released or made available. Software development costs for internal-use software are amortized to cost of revenues when products and enhancements are released or made available over the products' estimated economic lives, which are expected to be three Research and Development Costs Research and development expenses include salaries and personnel-related costs, including employee benefits, bonuses and stock-based compensation, third-party contractor expenses, software development costs, allocated overhead and other related expenses incurred in developing new solutions and enhancing existing solutions. Certain research and development costs that are related to the Company's software development, which include salaries and other personnel-related costs, comprised of employee benefits, stock-based compensation and bonuses attributed to programmers, software engineers and quality control teams working on the Company's software solutions, are capitalized and included in intangible assets, net on the consolidated balance sheets. Advertising Advertising costs of the Company are generally expensed the first time the advertising takes place. Advertising costs were $4.3 million, $4.4 million and $2.7 million for the years ended December 31, 2023, 2022 and 2021, respectively. The Company entered into a long-term stadium sponsorship agreement in 2020, and beginning in the second quarter of 2021, payments under this arrangement are deferred and expensed as advertising costs on a straight-line basis over the term of the arrangement. Sales Tax The Company presents sales taxes and other taxes collected from customers and remitted to governmental authorities on a net basis and, as such, excludes them from revenues. Comprehensive Loss Comprehensive loss includes net loss as well as other changes in stockholders' equity that result from transactions and economic events other than those with stockholders. Other comprehensive loss consists of net loss, unrealized gains and losses on available-for-sale investments, and foreign currency translation adjustments. Stock-Based Compensation Stock-based compensation includes grants of stock options, restricted stock units, or RSUs, performance-based restricted stock units, and purchase rights under our employee stock purchase plan, or ESPP, and is used to compensate employees, directors and consultants. All awards are measured at fair value on grant date and forfeitures are recognized as they occur. The Company values RSUs at the closing market price on the date of grant. RSUs typically vest in equal installments over a four-year period and compensation expense is recognized straight-line over the requisite service period. The Company values stock options and purchase rights under the ESPP using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires inputs including the risk-free interest rate, expected term and expected volatility and the Company assumes no dividend yield. Generally, options vest 25% on the one-year anniversary of the grant date with the balance vesting monthly over the following 36 months. The Company's ESPP has two six-month offering periods which commence on each June 1 and December 1. The Company recognizes compensation expense straight-line over the requisite service period for stock options and over the withholding period for the ESPP. The Company grants performance-based restricted stock units which provide for shares of common stock to be earned based on its total stockholder return, or TSR, performance relative to the TSR performance of specified stock indexes, or TSR PSUs, and previously referred to as Market Stock Units, or MSUs. The Company values TSR PSUs and MSUs on grant date using the Monte Carlo simulation model. The determination of fair value is affected by the Company's stock price and a number of assumptions including the expected volatility and the risk-free interest rate. The Company's expected volatility at the date of grant is based on the historical volatilities of its stock and peer firms' stocks and the Index over the performance period. The Company assumes no dividend yield and recognizes compensation expense ratably over the performance period of the award, as applicable. TSR PSUs and MSUs vest based on TSR relative to the TSR as set forth in the award agreement. The minimum percentage that can vest is 0%, with a maximum percentage of 200%. TSR PSUs and MSUs will vest over two-year and three-year performance periods. The Company recognizes compensation expense using the graded attribution method on a straight-line basis over the performance period for each award, as applicable. The Company also grants performance-based restricted stock units which provide for shares of common stock to be earned based on its attainment of Adjusted EBITDA as a percentage of non-GAAP Revenu |
