Dec. 31, 2021
Accounting Policies [Abstract]
Basis of presentation and principles of consolidation	Basis of Presentation and Principles of ConsolidationThe accompanying Consolidated Financial Statements include the accounts of NantHealth and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. These Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The results of operations of the entities disposed of are included in the Consolidated Financial Statements up to the date of disposal and, where appropriate, these operations have been reflected as discontinued operations.
Use of Estimates	Use of Estimates The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results may differ from those estimates. The estimates and assumptions used in the accompanying Consolidated Financial Statements are based upon management’s evaluation of the relevant facts and circumstances at the balance sheet date. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, accounts receivable allowance, useful lives of long-lived assets and intangible assets, income taxes, stock-based compensation, impairment of long-lived assets and intangible assets, and the expected performance against minimum reseller commitments. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which can affect the reported amounts of assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented.
Segment Reporting	Segment Reporting The chief operating decision maker for the Company is its Chief Executive Officer. The Chief Executive Officer reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company has one business activity and there are no segment managers who are held accountable for operations, operating results, or plans for levels or components below the consolidated unit level. Accordingly, management has determined that the Company operates in one reportable segment.
Revenue from Contracts with Customers	Revenue from Contracts with Customers Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue is recognized net of sales taxes collected from customers, which are subsequently remitted to governmental authorities. The Company’s revenue is generated from the following sources: •Software-as-a-service (“SaaS”) related - SaaS related revenue is generated from customers’ access to and usage of the Company’s hosted software solutions on a subscription basis for a specified contract term. In SaaS arrangements, the customer cannot take possession of the software during the term of the contract and generally has the right to access and use the software and receive any software upgrades published during the subscription period. SaaS contracts are accounted for as a single performance obligation, as implementation and hosting services are not distinct. As a result, the Company recognizes all fees, including any up front initial system implementation service fees, or other fees, ratably over time from when the system implementation or deployment services are completed, and where necessary accepted by the customer, over the contract term, as stated, or with consideration of termination for convenience clauses as discussed below. •Maintenance - Maintenance revenue includes technical support and maintenance on OpenNMS software during the contract term. Revenue is recognized over the maintenance or support term. The Company’s networking monitoring solutions typically consist of a term-based subscription to the OpenNMS software license and maintenance, which entitle customers to unspecified software updates and upgrades on a when-and-if-available basis. The Company has determined that its promises to transfer the software license and the related maintenance are not separately identifiable because the licensed software and the software updates and upgrades are highly interdependent and highly interrelated, working together to deliver a continuously updated networking monitoring solution. The Company therefore considers the software license and related maintenance obligations to represent a single, combined performance obligation with revenue recognized over the subscription period. •Professional services - Professional services revenue is generated from consulting services to help customers install, integrate and optimize OpenNMS, sponsored development, and training to assist customers deploy and use OpenNMS solutions. Sponsored development relates to professional services to build customer specific functionality, features, and enhancements into the OpenNMS open source platform. Revenue is recognized over time for most of the Company's contracts as performance obligations are satisfied, as the Company is continuously transferring control to the customer. Typically, revenue is recognized over time using direct labor hours as a measure of progress. If any significant obligations to the customer remain post-delivery, typically involving obligations relating to acceptance by the customer, revenue recognition is deferred until such obligations have been fulfilled. Customers are generally billed as the Company satisfies its performance obligations. Billings under certain fixed-price contracts may be based upon the achievement of specified milestones. Management assesses whether contracts entered into at, or near, the same time, should be combined, based on evaluation of the commercial objectives of the contracts. Certain of the Company’s customer contracts allow for termination for convenience, with advanced notice, without substantive termination penalty. In these cases, the Company has concluded the contract term is equal to the remaining non-cancelable period. Such termination rights do not allow for refunds other than prepaid services. These provisions do not affect when the Company commences revenue recognition. Contracts with Multiple Promises for Goods and Services The Company engages in various contracts with promises for multiple goods and services, which may generate revenue across any of the sources noted above. In certain contracts, the Company recognizes its proprietary software, software license, technical support, maintenance, consulting services, sponsored development services, training, certain professional services, and other software-related services as distinct performance obligations. Standalone selling prices (“SSP”) are required to be allocated and revenue recognized for each distinct performance obligation within each contract. Judgment is required to determine the SSP for each distinct performance obligation. The SSP for each performance obligation is determined by considering contracts in which the good or service is sold separately and other factors, including market conditions and the Company’s experience selling similar goods and services, as well as costs and margins achieved. In some cases, to estimate the SSP, the Company first estimates the selling price of each performance obligation for which an SSP is observable and then estimates the SSP of the remaining performance obligation as the residual contractual amount. Generally, consulting and sponsored development professional services do not involve significant integration or customization of the OpenNMS software. As such, consulting and sponsored development are considered distinct performance obligations. The Company has reseller arrangements, and for each promised good or service, the Company evaluates whether it is a principal or an agent. The Company assesses control in terms of relevant indicators of performance, inventory, and pricing risk, such as which party negotiates pricing with the end customer and which party is ultimately responsible for fulfilling services, transferring goods and services, and ensuring support.
Cost of Revenue	Cost of Revenue Cost of revenue includes associated salaries and fringe benefits, stock-based compensation, consultant costs, direct reimbursable travel expenses, depreciation related to software developed for internal use, depreciation related to lab equipment, and other direct engagement costs associated with the design, development, sale and installation of systems, including system support and maintenance services for customers. System support includes ongoing customer assistance for software updates and upgrades, installation, training and functionality. All service costs, except development of internal use software and deferred implementation costs, are expensed when incurred. Amortization of deferred implementation costs are also included in cost of revenue. Cost of revenue associated with each of the Company’s revenue sources consists of the following types of costs: •Software-as-a-service related - SaaS related cost of revenue includes personnel-related costs, amortization of deferred implementation costs, amortization of internal-use software, and other direct costs associated with the delivery and hosting of the Company's subscription services. •Maintenance - Maintenance cost of revenue includes personnel-related costs, amortization of internal-use software, and other direct costs associated with the ongoing support or maintenance provided to the Company’s customers. •Professional services - Professional services cost of revenue include personnel-related costs and other direct costs associated with consulting, sponsored development, and training provided to the Company's customers.
Selling, General and Administrative Expenses	Selling, General and Administrative ExpensesSelling, general and administrative expense consists primarily of personnel-related expenses for the Company's sales and marketing, finance, legal, human resources, administrative personnel, stock-based compensation, advertising and marketing promotions of NantHealth solutions, and corporate shared services fees from NantWorks. This includes amortization of deferred commission costs. It also includes trade show and event costs, sponsorship costs, point of purchase display expenses and related amortization as well as legal costs, facility costs, consulting and professional fees, insurance and other corporate and administrative costs.
Research and Development Expenses	Research and Development Expenses Research and development (“R&D”) costs incurred to establish the technological feasibility of software to be sold are expensed as incurred. These expenses include the costs of the Company’s proprietary R&D efforts, as well as costs incurred in connection with certain licensing arrangements. Research and development expenses consist primarily of personnel-related costs for employees working on development of solutions, including salaries, benefits, and stock-based compensation. Also included are non-personnel costs such as consulting and professional fees to third-party development resources. Substantially all of the Company's research and development expenses are related to developing new software solutions and improving its existing software solutions. These costs incurred in the research and development of new software products and maintenance to existing software products are expensed as incurred. These costs are associated with both the preliminary project stage and post-implementation stage of internal-use software. Qualifying costs associated with the application development stage are capitalized.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation arrangements granted to employees in accordance with ASC 718, Compensation–Stock Compensation, by measuring the grant date fair value of the award and recognizing the resulting expense over the period during which the employee is required to perform service in exchange for the award. The Company accounts for stock-based compensation arrangements issued to nonemployees using the fair value approach prescribed by ASC 505-50, Equity-Based Payments to Non-Employees. Prior to January 1, 2019 when the Company adopted ASU No. 2018-07, Improvement to nonemployee share-based payment accounting, the value of nonemployee stock-based compensation was re-measured at the end of each reporting period until the award vests and is recognized as stock-based compensation expense over the period during which the nonemployee provides the services. After the adoption of ASU No. 2018-07, the value of nonemployee stock-based compensation is measured at the grant date fair value of the award and the resulting expense is recognized over the period during which the nonemployee provides the services. Stock-based compensation expense for both employee and nonemployee awards is recognized on a straight-line basis over the appropriate service period for awards that are only subject to service conditions and is recognized using the accelerated attribution method for awards that are subject to performance conditions. Stock-based compensation expense is only recognized for awards subject to performance conditions if it is probable that the performance condition will be achieved. All excess tax benefits and tax deficiencies are recognized as income tax benefit or expense in the income statement as discrete items in the reporting period in which they occur, and such tax benefits and tax deficiencies are not included in the estimate of an entity’s annual effective tax rate, applied on a prospective basis. The recognition of excess tax benefits is deferred until the benefit is realized through a reduction to taxes payable. When the Company applies the treasury stock method in calculating diluted earnings per share, excess tax benefits, if applicable, and deficiencies from the calculation of assumed proceeds are excluded since such amounts are recognized in the income statement. Excess tax benefits if applicable, are classified as operating activities in the same manner as other cash flows related to income taxes on the statement of cash flows. The Company has elected to account for forfeitures when they occur. Cash paid by the Company when directly withholding shares for tax withholding purposes is classified as a financing activity in the Consolidated Statements of Cash Flows
Change In Fair Value Of Bookings Commitment	Change in Fair Value of Bookings Commitment The Company has classified the Bookings Commitment assumed upon the disposal of the provider/patient engagement solutions business described in Note 12 as part of accrued and other current liabilities and other liabilities in the Consolidated Balance Sheets. This liability is subject to re-measurement at each balance sheet date, and the Company recognizes any changes in fair value within other income/expense, net. The fair value of the liability is estimated using a Monte Carlo Simulation model to calculate average payments due under the Bookings Commitment, based on management's estimate of its performance in securing bookings and resulting annual payments, discounted at the cost of debt based on a yield curve. The change in the fair value of this liability is primarily due to changes in the costs of debt based on a yield curve and the passage of time (see Note 12). Management believes the assumptions used on projected financial information is reasonable, but those assumptions require judgment and are forward looking in nature. However, actual results may differ materially from those projections. The fair value of the Bookings Commitment is most sensitive to management's estimate of the discount rate applied to present value the liability.
Income Taxes	Income Taxes The Company records the federal and state tax provision of the consolidated group and foreign tax provision of its foreign subsidiaries. ASC 740, Income Taxes, provides the accounting treatment for uncertainty in income taxes recognized in an enterprise’s financial statements. ASC 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognizing, classification, interest and penalties, accounting in interim periods, disclosure, and transition. As part of the process of preparing its Consolidated Financial Statements, the Company is required to estimate its provision for income taxes in each of the tax jurisdictions in which the Company conducts business. This process involves estimating the actual current tax expense in conjunction with the evaluation and measurement of temporary differences resulting from differing treatment of certain items for tax and accounting purposes. These temporary differences result in the establishment of deferred tax assets and liabilities, which are recorded on a net basis and included in the Company's Consolidated Balance Sheets. The Company then evaluates on a periodic basis the probability that the net deferred tax assets will be recovered and therefore realized from future taxable income and to the extent the Company believes that recovery is not more likely than not, a valuation allowance is established to address such risk resulting in an additional related provision for income taxes during the period. Significant management judgment is required in determining its provision for income taxes, its deferred tax assets and liabilities, tax contingencies, unrecognized tax benefits, and any required valuation allowance, including taking into consideration the probability of the tax contingencies being incurred. Management assesses this probability based upon information provided by its tax advisers, its legal advisers and similar tax cases. If at a later time its assessment of the probability of these tax contingencies changes, its accrual for such tax uncertainties may increase or decrease. The Company has a valuation allowance due to management’s overall assessment of risks and uncertainties related to its future ability to realize and, hence, utilize certain deferred tax assets, primarily consisting of net operating losses ("NOLs"), carry forward temporary differences and future tax deductions. The effective tax rate for annual and interim reporting periods could be impacted if uncertain tax positions that are not recognized are settled at an amount which differs from the Company's estimate. Finally, if the Company is impacted by a change in the valuation allowance resulting from a change in judgment regarding the realizability of deferred tax assets, such effect will be recognized in the interim period in which the change occurs.
Net Loss Per Share	Net Loss Per ShareBasic net loss per common share attributable to NantHealth is computed by dividing the net loss attributable to NantHealth by the weighted average number of shares of common stock outstanding during the respective periods, without consideration of common stock equivalents. Diluted net loss per common share attributable to NantHealth is computed by dividing the net loss attributable to NantHealth by the weighted average number of shares of common stock outstanding during the respective periods, adjusted to give effect to potentially dilutive securities. However, potentially dilutive securities are excluded from the computation of diluted net loss per common share attributable to NantHealth to the extent that their effect is anti-dilutive. If there is a net loss from continuing operations attributable to NantHealth, diluted net loss per share attributable to NantHealth is computed in the same manner as basic net loss per share attributable to NantHealth is computed, even if the Company reports net income as a result of discontinued operations attributable to NantHealth. The Company applies treasury method in calculating weighted average dilutive number of shares for its stock plans. The convertible notes will be reflected in diluted loss per share using the if-converted method until the Company makes an irrevocable settlement election requiring the future settlement of the convertible notes to have the principal amount settled in cash.
Foreign Currency Translation	Foreign Currency Translation The Company has operations and holds assets in various foreign countries. The local currency is the functional currency for the Company’s subsidiaries in the United Kingdom and Canada. Assets and liabilities are translated at end-of-period exchange rates while revenues and expenses are translated at the average exchange rates in effect during the period. Equity is translated at historical rates and the resulting cumulative translation adjustments are included as a component of accumulated other comprehensive income/loss until the translation adjustments are realized.
Leases	Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in the Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, net, other current liabilities, and other liabilities in the Consolidated Balance Sheets. The Company currently does not have any finance leases. Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company's leases do not provide an implicit rate; therefore, the Company uses the incremental borrowing rate based on the information available at commencement date, or at January 1, 2019 for the Company's leases on transition to ASC 842, in determining the present value of future payments. The operating lease ROU asset excludes lease incentives and initial direct costs incurred. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components. For data center leases and real estate leases, the Company accounts for the lease and non-lease components as a single lease component. The Company treats data center leases with lease terms of less than one year as short-term leases and recognizes the lease expense straight-line over the lease term.
Business Combinations	Business Combinations Business combinations are accounted for using the acquisition method of accounting. Under the acquisition method, assets acquired and liabilities assumed are recorded at their respective fair values as of the acquisition date. Any excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Management routinely monitors the factors impacting the acquired assets and liabilities. Transaction related costs are expensed as incurred. The operating results of the acquired business are reflected in the Company’s Consolidated Financial Statements as of the acquisition date.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are classified and disclosed in one of the following three categories: •Level 1—Quoted prices for identical assets or liabilities in active markets; •Level 2—Quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in markets that are not active or are directly or indirectly observable; and •Level 3—Unobservable inputs that reflect estimates and assumptions. The carrying amounts reported in the Consolidated Balance Sheets for cash and cash equivalents, accounts receivable, accounts payable, notes payable, deferred revenue, and other current monetary assets and liabilities approximate fair value because of the immediate or short-term maturity of these financial instruments. In accordance with this guidance, the Company measures its cash equivalents at fair value. The Company’s cash equivalents are classified within Level 1. The Company's fair value estimate of the Bookings Commitment and convertibles notes are based on Level 3 inputs.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all unrestricted, highly liquid investments with an initial maturity of three months or less to be cash equivalents. These amounts are stated at cost, which approximates fair value. At December 31, 2021 and 2020, cash equivalents were deposited in financial institutions and consisted of immediately available fund balances. Cash and cash equivalents are maintained at stable financial institutions, generally at amounts in excess of federally insured limits, which represents a concentration of credit risk. The Company has not experienced any losses on deposits of cash and cash equivalents to date.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts. The allowance for doubtful accounts is based on management’s assessment of the collectability of accounts. The Company regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice and the collection history of each customer to determine whether a specific allowance is appropriate. Accounts receivable deemed uncollectible are charged against bad debt expense when identified.
Insurance Recoveries	Insurance Recoveries The Company records probable insurance recoveries gross of related liabilities. The income and expense related to these amounts are recorded net in selling, general and administrative expenses. If the recoveries exceed the loss recognized in the financial statements, such recoveries are recorded in other expense, net, once any contingencies relating to the insurance claim have been resolved.
Property, Plant and Equipment, net	Property, Plant and Equipment, net Property, plant and equipment received in connection with business combinations are recorded at fair value. Property, plant and equipment acquired in the normal course of business are recorded at cost. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets (see Note 7). Maintenance and repairs are charged to expense as incurred while expenditures for refurbishments and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. Property, plant and equipment is tested for impairment, and depreciation estimates and methods are reviewed, whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. Internal-Use Software The Company accounts for the costs of computer software obtained or developed for internal use in accordance with ASC 350, Intangibles—Goodwill and Other. Computer software development costs are expensed as incurred, except for internal-use software costs that qualify for capitalization, and include employee related expenses, including salaries, benefits and stock-based compensation expenses; costs of computer hardware and software; and costs incurred in developing features and functionality. These capitalized costs are included in property and equipment in the Consolidated Balance Sheets. The Company expenses costs incurred in the preliminary project and post implementation stages of software development and capitalizes qualifying costs incurred in the application development stage and costs associated with significant enhancements to existing internal-use software applications. Software costs are amortized using the straight-line method over an estimated useful life of three years commencing when the software project is ready for its intended use. Internal-use software is tested for impairment where assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets whenever events or changes in circumstances indicate that its carrying amount may not be recoverable.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill acquired in a business combination and determined to have an indefinite useful life is not amortized but is tested for impairment annually as of October 1 or between annual tests when an impairment indicator exists. In the event there is a change in reporting units or segments, the Company will test for impairment at the reporting unit. A component of an operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and segment management regularly reviews the operating results of that component. As part of the annual impairment test, the Company may conduct an assessment of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. In a qualitative assessment, the Company would consider the macroeconomic conditions, including any deterioration of general conditions, industry and market conditions, including any deterioration in the environment where the reporting unit operates, increased competition, changes in the products/services and regulator and political developments; cost of doing business; overall financial performance, including any declining cash flows and performance in relation to planned revenues and earnings in past periods; other relevant reporting unit specific facts, such as changes in management or key personnel or pending litigation, and events affecting the reporting unit, including changes in the carrying value of net assets. If an optional qualitative goodwill impairment assessment is not performed, the Company is required to determine the fair value of each reporting unit. If a reporting unit’s carrying value is in excess of its fair value, such excess is recorded as an impairment loss. Under the accounting guidance, there is no requirement to perform a qualitative assessment for reporting units with zero or negative carrying values. Accounting guidance requires that definite-lived intangible assets be amortized over their respective estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Amortization of finite-lived intangible assets is provided over their estimated useful lives on a straight-line basis or the pattern in which economic benefits are consumed, if reliably determinable. If the estimates of the useful lives change, the Company amortizes the remaining book value over the remaining useful lives or, if an asset is deemed to be impaired, a write-down of the value of the asset to its fair value may be required at such time. The Company reviews its finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
Investment in Related Party	Investment in Related Party Investment in and advances to a related party in which the Company has a substantial ownership interest of approximately 20% to 50%, or for which the Company exercises significant influence but not control over policy decisions, are accounted for by the equity method. An investment in a limited liability company that is similar to a partnership is also accounted for under the equity method if more than minor influence over the operation of the investee exists (generally through more than 3-5% ownership). As part of that accounting, the Company recognizes gains and losses that arise from the issuance of stock by a related party that results in changes in the Company’s proportionate share of the dollar amount of the related party’s equity. Investment in related party is assessed for possible impairment when events indicate that the fair value of the investment may be below the Company’s carrying value. When such a condition is deemed to be other than temporary, the carrying value of the investment is written down to its fair value, and the amount of the write-down is included in net loss. In making the determination as to whether a decline is other than temporary, the Company considers such factors as the duration and extent of the decline, the investee’s financial performance, and the Company’s ability and intention to retain its investment for a period that will be sufficient to allow for any anticipated recovery in the investment’s market value. The new cost basis of investments in these equity investees is not changed for subsequent recoveries in fair value. As of June 30, 2020, the Company determined that other-than-temporary impairments in the full remaining carrying value of the investment in NantOmics have occurred (see Note 10). After the Company's equity method investment in NantOmics was reduced to zero, the Company no longer applies the equity method to record additional losses until NantOmics subsequently reports net income and that net income equals the share of net losses not recognized during the period the equity method was suspended.
Deferred Revenue	Deferred Revenue The Company records deferred revenue when it receives cash from customers prior to meeting the applicable revenue recognition criteria. The Company uses judgment in determining the period over which the deliverables are recognized as revenue. As of December 31, 2021 and 2020, current and non-current deferred revenue are comprised of deferrals for fees related to SaaS arrangements, technical support and maintenance, services and other revenue. Non-current deferred revenue as of December 31, 2021 is expected to be recognized in a period more than 12 months after that date.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU') No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40). This update simplifies the accounting for convertible instruments by eliminating the cash conversion and beneficial conversion feature models which require separate accounting for embedded conversion features. This update also amends the guidance for the derivatives scope exception for contracts in an entity's own equity to reduce form-over-substance-based accounting conclusions and requires the application of the if-converted method for calculating diluted earnings per share. ASU No. 2020-06 is effective for fiscal periods beginning after December 15, 2023. The Company early adopted ASU 2020-06 on a modified retrospective basis on January 1, 2021. The cumulative effect of the adoption on accumulated deficit and additional paid-in capital was a decrease of $8,572 and $14,318, respectively, on January 1, 2021. Under the new guidance, the Company will record less noncash interest expense going forward as the cash conversion model that was previously applied is now eliminated. Upcoming Accounting Standard Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which changes how companies measure credit losses on most financial instruments measured at amortized cost, such as loans, receivables and held-to-maturity debt securities. Rather than generally recognizing credit losses when it is probable that the loss has been incurred, the revised guidance requires companies to recognize an allowance for credit losses for the difference between the amortized cost basis of a financial instrument and the amount of amortized cost that the Company expects to collect over the instrument's contractual life. ASU No. 2016-13 is effective for fiscal periods beginning after December 15, 2022 and must be adopted as a cumulative effect adjustment to retained earnings. Early adoption is permitted. The Company is still evaluating the effects of this ASU. Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants, and the SEC did not have, nor are believed by management to have, a material impact on the Company's present or future Consolidated Financial Statements.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2021

Basis of presentation and principles of consolidation

Basis of Presentation and Principles of ConsolidationThe accompanying Consolidated Financial Statements include the accounts of NantHealth and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. These Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The results of operations of the entities disposed of are included in the Consolidated Financial Statements up to the date of disposal and, where appropriate, these operations have been reflected as discontinued operations.

Use of Estimates

The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Actual results may differ from those estimates. The estimates and assumptions used in the accompanying Consolidated Financial Statements are based upon management’s evaluation of the relevant facts and circumstances at the balance sheet date. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, accounts receivable allowance, useful lives of long-lived assets and intangible assets, income taxes, stock-based compensation, impairment of long-lived assets and intangible assets, and the expected performance against minimum reseller commitments. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which can affect the reported amounts of assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented.

Segment Reporting

The chief operating decision maker for the Company is its Chief Executive Officer. The Chief Executive Officer reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company has one business activity and there are no segment managers who are held accountable for operations, operating results, or plans for levels or components below the consolidated unit level. Accordingly, management has determined that the Company operates in one reportable segment.

Revenue from Contracts with Customers

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. Revenue is recognized net of sales taxes collected from customers, which are subsequently remitted to governmental authorities. The Company’s revenue is generated from the following sources:

•Software-as-a-service (“SaaS”) related - SaaS related revenue is generated from customers’ access to and usage of the Company’s hosted software solutions on a subscription basis for a specified contract term. In SaaS arrangements, the customer cannot take possession of the software during the term of the contract and generally has the right to access and use the software and receive any software upgrades published during the subscription period.

SaaS contracts are accounted for as a single performance obligation, as implementation and hosting services are not distinct. As a result, the Company recognizes all fees, including any up front initial system implementation service fees, or other fees, ratably over time from when the system implementation or deployment services are completed, and where necessary accepted by the customer, over the contract term, as stated, or with consideration of termination for convenience clauses as discussed below.

•Maintenance - Maintenance revenue includes technical support and maintenance on OpenNMS software during the contract term. Revenue is recognized over the maintenance or support term.

The Company’s networking monitoring solutions typically consist of a term-based subscription to the OpenNMS software license and maintenance, which entitle customers to unspecified software updates and upgrades on a when-and-if-available basis. The Company has determined that its promises to transfer the software license and the related maintenance are not separately identifiable because the licensed software and the software updates and upgrades are highly interdependent and highly interrelated, working together to deliver a continuously updated networking monitoring solution. The Company therefore considers the software license and related maintenance obligations to represent a single, combined performance obligation with revenue recognized over the subscription period.

•Professional services - Professional services revenue is generated from consulting services to help customers install, integrate and optimize OpenNMS, sponsored development, and training to assist customers deploy and use OpenNMS solutions. Sponsored development relates to professional services to build customer specific functionality, features, and enhancements into the OpenNMS open source platform.

Revenue is recognized over time for most of the Company's contracts as performance obligations are satisfied, as the Company is continuously transferring control to the customer. Typically, revenue is recognized over time using direct labor hours as a measure of progress. If any significant obligations to the customer remain post-delivery, typically involving obligations relating to acceptance by the customer, revenue recognition is deferred until such obligations have been fulfilled.

Customers are generally billed as the Company satisfies its performance obligations. Billings under certain fixed-price contracts may be based upon the achievement of specified milestones.

Management assesses whether contracts entered into at, or near, the same time, should be combined, based on evaluation of the commercial objectives of the contracts.

Certain of the Company’s customer contracts allow for termination for convenience, with advanced notice, without substantive termination penalty. In these cases, the Company has concluded the contract term is equal to the remaining non-cancelable period. Such termination rights do not allow for refunds other than prepaid services. These provisions do not affect when the Company commences revenue recognition.

Contracts with Multiple Promises for Goods and Services

The Company engages in various contracts with promises for multiple goods and services, which may generate revenue across any of the sources noted above.

In certain contracts, the Company recognizes its proprietary software, software license, technical support, maintenance, consulting services, sponsored development services, training, certain professional services, and other software-related services as distinct performance obligations.

Standalone selling prices (“SSP”) are required to be allocated and revenue recognized for each distinct performance obligation within each contract. Judgment is required to determine the SSP for each distinct performance obligation. The SSP for each performance obligation is determined by considering contracts in which the good or service is sold separately and other factors, including market conditions and the Company’s experience selling similar goods and services, as well as costs and margins achieved. In some cases, to estimate the SSP, the Company first estimates the selling price of each performance obligation for which an SSP is observable and then estimates the SSP of the remaining performance obligation as the residual contractual amount.

Generally, consulting and sponsored development professional services do not involve significant integration or customization of the OpenNMS software. As such, consulting and sponsored development are considered distinct performance obligations.

The Company has reseller arrangements, and for each promised good or service, the Company evaluates whether it is a principal or an agent. The Company assesses control in terms of relevant indicators of performance, inventory, and pricing risk, such as which party negotiates pricing with the end customer and which party is ultimately responsible for fulfilling services, transferring goods and services, and ensuring support.

Cost of Revenue

Cost of revenue includes associated salaries and fringe benefits, stock-based compensation, consultant costs, direct reimbursable travel expenses, depreciation related to software developed for internal use, depreciation related to lab equipment, and other direct engagement costs associated with the design, development, sale and installation of systems, including system support and maintenance services for customers. System support includes ongoing customer assistance for software updates and upgrades, installation, training and functionality. All service costs, except development of internal use software and deferred implementation costs, are expensed when incurred. Amortization of deferred implementation costs are also included in cost of revenue. Cost of revenue associated with each of the Company’s revenue sources consists of the following types of costs:

•Software-as-a-service related - SaaS related cost of revenue includes personnel-related costs, amortization of deferred implementation costs, amortization of internal-use software, and other direct costs associated with the delivery and hosting of the Company's subscription services.

•Maintenance - Maintenance cost of revenue includes personnel-related costs, amortization of internal-use software, and other direct costs associated with the ongoing support or maintenance provided to the Company’s customers.

•Professional services - Professional services cost of revenue include personnel-related costs and other direct costs associated with consulting, sponsored development, and training provided to the Company's customers.

Selling, General and Administrative Expenses

Selling, General and Administrative ExpensesSelling, general and administrative expense consists primarily of personnel-related expenses for the Company's sales and marketing, finance, legal, human resources, administrative personnel, stock-based compensation, advertising and marketing promotions of NantHealth solutions, and corporate shared services fees from NantWorks. This includes amortization of deferred commission costs. It also includes trade show and event costs, sponsorship costs, point of purchase display expenses and related amortization as well as legal costs, facility costs, consulting and professional fees, insurance and other corporate and administrative costs.

Research and Development Expenses

Research and development (“R&D”) costs incurred to establish the technological feasibility of software to be sold are expensed as incurred. These expenses include the costs of the Company’s proprietary R&D efforts, as well as costs incurred in connection with certain licensing arrangements.

Research and development expenses consist primarily of personnel-related costs for employees working on development of solutions, including salaries, benefits, and stock-based compensation. Also included are non-personnel costs such as consulting and professional fees to third-party development resources.

Substantially all of the Company's research and development expenses are related to developing new software solutions and improving its existing software solutions.

These costs incurred in the research and development of new software products and maintenance to existing software products are expensed as incurred. These costs are associated with both the preliminary project stage and post-implementation stage of internal-use software. Qualifying costs associated with the application development stage are capitalized.

Stock-Based Compensation

The Company accounts for stock-based compensation arrangements granted to employees in accordance with ASC 718, Compensation–Stock Compensation, by measuring the grant date fair value of the award and recognizing the resulting expense over the period during which the employee is required to perform service in exchange for the award.

The Company accounts for stock-based compensation arrangements issued to nonemployees using the fair value approach prescribed by ASC 505-50, Equity-Based Payments to Non-Employees. Prior to January 1, 2019 when the Company adopted ASU No. 2018-07, Improvement to nonemployee share-based payment accounting, the value of nonemployee stock-based compensation was re-measured at the end of each reporting period until the award vests and is recognized as stock-based compensation expense over the period during which the nonemployee provides the services. After the adoption of ASU No. 2018-07, the value of nonemployee stock-based compensation is measured at the grant date fair value of the award and the resulting expense is recognized over the period during which the nonemployee provides the services.

Stock-based compensation expense for both employee and nonemployee awards is recognized on a straight-line basis over the appropriate service period for awards that are only subject to service conditions and is recognized using the accelerated attribution method for awards that are subject to performance conditions. Stock-based compensation expense is only recognized for awards subject to performance conditions if it is probable that the performance condition will be achieved.

All excess tax benefits and tax deficiencies are recognized as income tax benefit or expense in the income statement as discrete items in the reporting period in which they occur, and such tax benefits and tax deficiencies are not included in the estimate of an entity’s annual effective tax rate, applied on a prospective basis. The recognition of excess tax benefits is deferred until the benefit is realized through a reduction to taxes payable. When the Company applies the treasury stock method in calculating diluted earnings per share, excess tax benefits, if applicable, and deficiencies from the calculation of assumed proceeds are excluded since such amounts are recognized in the income statement. Excess tax benefits if applicable, are classified as operating activities in the same manner as other cash flows related to income taxes on the statement of cash flows.

The Company has elected to account for forfeitures when they occur. Cash paid by the Company when directly withholding shares for tax withholding purposes is classified as a financing activity in the Consolidated Statements of Cash Flows

Change In Fair Value Of Bookings Commitment

Change in Fair Value of Bookings Commitment

The Company has classified the Bookings Commitment assumed upon the disposal of the provider/patient engagement solutions business described in Note 12 as part of accrued and other current liabilities and other liabilities in the Consolidated Balance Sheets. This liability is subject to re-measurement at each balance sheet date, and the Company recognizes any changes in fair value within other income/expense, net. The fair value of the liability is estimated using a Monte Carlo Simulation model to calculate average payments due under the Bookings Commitment, based on management's estimate of its performance in securing bookings and resulting annual payments, discounted at the cost of debt based on a yield curve. The change in the fair value of this liability is primarily due to changes in the costs of debt based on a yield curve and the passage of time (see Note 12).

Management believes the assumptions used on projected financial information is reasonable, but those assumptions require judgment and are forward looking in nature. However, actual results may differ materially from those projections. The fair value of the Bookings Commitment is most sensitive to management's estimate of the discount rate applied to present value the liability.

Income Taxes

The Company records the federal and state tax provision of the consolidated group and foreign tax provision of its foreign subsidiaries.

ASC 740, Income Taxes, provides the accounting treatment for uncertainty in income taxes recognized in an enterprise’s financial statements. ASC 740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognizing, classification, interest and penalties, accounting in interim periods, disclosure, and transition.

As part of the process of preparing its Consolidated Financial Statements, the Company is required to estimate its provision for income taxes in each of the tax jurisdictions in which the Company conducts business. This process involves estimating the actual current tax expense in conjunction with the evaluation and measurement of temporary differences resulting from differing treatment of certain items for tax and accounting purposes. These temporary differences result in the establishment of deferred tax assets and liabilities, which are recorded on a net basis and included in the Company's Consolidated Balance Sheets. The Company then evaluates on a periodic basis the probability that the net deferred tax assets will be recovered and therefore realized from future taxable income and to the extent the Company believes that recovery is not more likely than not, a valuation allowance is established to address such risk resulting in an additional related provision for income taxes during the period.

Significant management judgment is required in determining its provision for income taxes, its deferred tax assets and liabilities, tax contingencies, unrecognized tax benefits, and any required valuation allowance, including taking into consideration the probability of the tax contingencies being incurred. Management assesses this probability based upon information provided by its tax advisers, its legal advisers and similar tax cases. If at a later time its assessment of the probability of these tax contingencies changes, its accrual for such tax uncertainties may increase or decrease.

The Company has a valuation allowance due to management’s overall assessment of risks and uncertainties related to its future ability to realize and, hence, utilize certain deferred tax assets, primarily consisting of net operating losses ("NOLs"), carry forward temporary differences and future tax deductions.

The effective tax rate for annual and interim reporting periods could be impacted if uncertain tax positions that are not recognized are settled at an amount which differs from the Company's estimate. Finally, if the Company is impacted by a change in the valuation allowance resulting from a change in judgment regarding the realizability of deferred tax assets, such effect will be recognized in the interim period in which the change occurs.

Net Loss Per Share

Net Loss Per ShareBasic net loss per common share attributable to NantHealth is computed by dividing the net loss attributable to NantHealth by the weighted average number of shares of common stock outstanding during the respective periods, without consideration of common stock equivalents. Diluted net loss per common share attributable to NantHealth is computed by dividing the net loss attributable to NantHealth by the weighted average number of shares of common stock outstanding during the respective periods, adjusted to give effect to potentially dilutive securities. However, potentially dilutive securities are excluded from the computation of diluted net loss per common share attributable to NantHealth to the extent that their effect is anti-dilutive. If there is a net loss from continuing operations attributable to NantHealth, diluted net loss per share attributable to NantHealth is computed in the same manner as basic net loss per share attributable to NantHealth is computed, even if the Company reports net income as a result of discontinued operations attributable to NantHealth. The Company applies treasury method in calculating weighted average dilutive number of shares for its stock plans. The convertible notes will be reflected in diluted loss per share using the if-converted method until the Company makes an irrevocable settlement election requiring the future settlement of the convertible notes to have the principal amount settled in cash.

Foreign Currency Translation

The Company has operations and holds assets in various foreign countries. The local currency is the functional currency for the Company’s subsidiaries in the United Kingdom and Canada. Assets and liabilities are translated at end-of-period exchange rates while revenues and expenses are translated at the average exchange rates in effect during the period. Equity is translated at historical rates and the resulting cumulative translation adjustments are included as a component of accumulated other comprehensive income/loss until the translation adjustments are realized.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, other current liabilities, and operating lease liabilities in the Consolidated Balance Sheets. Finance leases are included in property, plant, and equipment, net, other current liabilities, and other liabilities in the Consolidated Balance Sheets. The Company currently does not have any finance leases.

Operating lease ROU assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company's leases do not provide an implicit rate; therefore, the Company uses the incremental borrowing rate based on the information available at commencement date, or at January 1, 2019 for the Company's leases on transition to ASC 842, in determining the present value of future payments. The operating lease ROU asset excludes lease incentives and initial direct costs incurred. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.

The Company has lease agreements with lease and non-lease components. For data center leases and real estate leases, the Company accounts for the lease and non-lease components as a single lease component.

The Company treats data center leases with lease terms of less than one year as short-term leases and recognizes the lease expense straight-line over the lease term.

Business Combinations

Business combinations are accounted for using the acquisition method of accounting. Under the acquisition method, assets acquired and liabilities assumed are recorded at their respective fair values as of the acquisition date. Any excess of the purchase price over the estimated fair values of the net assets acquired is recorded as goodwill. Management routinely monitors the factors impacting the acquired assets and liabilities. Transaction related costs are expensed as incurred. The operating results of the acquired business are reflected in the Company’s Consolidated Financial Statements as of the acquisition date.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are classified and disclosed in one of the following three categories:

•Level 1—Quoted prices for identical assets or liabilities in active markets;

•Level 2—Quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in markets that are not active or are directly or indirectly observable; and

•Level 3—Unobservable inputs that reflect estimates and assumptions.

The carrying amounts reported in the Consolidated Balance Sheets for cash and cash equivalents, accounts receivable, accounts payable, notes payable, deferred revenue, and other current monetary assets and liabilities approximate fair value because of the immediate or short-term maturity of these financial instruments.

In accordance with this guidance, the Company measures its cash equivalents at fair value. The Company’s cash equivalents are classified within Level 1.

The Company's fair value estimate of the Bookings Commitment and convertibles notes are based on Level 3 inputs.

Cash and Cash Equivalents

The Company considers all unrestricted, highly liquid investments with an initial maturity of three months or less to be cash equivalents. These amounts are stated at cost, which approximates fair value. At December 31, 2021 and 2020, cash equivalents were deposited in financial institutions and consisted of immediately available fund balances. Cash and cash equivalents are maintained at stable financial institutions, generally at amounts in excess of federally insured limits, which represents a concentration of credit risk. The Company has not experienced any losses on deposits of cash and cash equivalents to date.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recorded at the invoiced amount, net of allowances for doubtful accounts. The allowance for doubtful accounts is based on management’s assessment of the collectability of accounts. The Company regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice and the collection history of each customer to determine whether a specific allowance is appropriate. Accounts receivable deemed uncollectible are charged against bad debt expense when identified.

Insurance Recoveries

The Company records probable insurance recoveries gross of related liabilities. The income and expense related to these amounts are recorded net in selling, general and administrative expenses. If the recoveries exceed the loss recognized in the financial statements, such recoveries are recorded in other expense, net, once any contingencies relating to the insurance claim have been resolved.

Property, Plant and Equipment, net

Property, plant and equipment received in connection with business combinations are recorded at fair value. Property, plant and equipment acquired in the normal course of business are recorded at cost. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets (see Note 7). Maintenance and repairs are charged to expense as incurred while expenditures for refurbishments and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized. Property, plant and equipment is tested for impairment, and depreciation estimates and methods are reviewed, whenever events or changes in circumstances indicate that its carrying amount may not be recoverable.

Internal-Use Software

The Company accounts for the costs of computer software obtained or developed for internal use in accordance with ASC 350, Intangibles—Goodwill and Other. Computer software development costs are expensed as incurred, except for internal-use software costs that qualify for capitalization, and include employee related expenses, including salaries, benefits and stock-based compensation expenses; costs of computer hardware and software; and costs incurred in developing features and functionality. These capitalized costs are included in property and equipment in the Consolidated Balance Sheets. The Company expenses costs incurred in the preliminary project and post implementation stages of software development and capitalizes qualifying costs incurred in the application development stage and costs associated with significant enhancements to existing internal-use software applications. Software costs are amortized using the straight-line method over an estimated useful life of three years commencing when the software project is ready for its intended use. Internal-use software is tested for impairment where assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets whenever events or changes in circumstances indicate that its carrying amount may not be recoverable.

Goodwill and Intangible Assets

Goodwill acquired in a business combination and determined to have an indefinite useful life is not amortized but is tested for impairment annually as of October 1 or between annual tests when an impairment indicator exists. In the event there is a change in reporting units or segments, the Company will test for impairment at the reporting unit. A component of an operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and segment management regularly reviews the operating results of that component.

As part of the annual impairment test, the Company may conduct an assessment of qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. In a qualitative assessment, the Company would consider the macroeconomic conditions, including any deterioration of general conditions, industry and market conditions, including any deterioration in the environment where the reporting unit operates, increased competition, changes in the products/services and regulator and political developments; cost of doing business; overall financial performance, including any declining cash flows and performance in relation to planned revenues and earnings in past periods; other relevant reporting unit specific facts, such as changes in management or key personnel or pending litigation, and events affecting the reporting unit, including changes in the carrying value of net assets.

If an optional qualitative goodwill impairment assessment is not performed, the Company is required to determine the fair value of each reporting unit. If a reporting unit’s carrying value is in excess of its fair value, such excess is recorded as an impairment loss. Under the accounting guidance, there is no requirement to perform a qualitative assessment for reporting units with zero or negative carrying values.

Accounting guidance requires that definite-lived intangible assets be amortized over their respective estimated useful lives and reviewed for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Amortization of finite-lived intangible assets is provided over their estimated useful lives on a straight-line basis or the pattern in which economic benefits are consumed, if reliably determinable. If the estimates of the useful lives change, the Company amortizes the remaining book value over the remaining useful lives or, if an asset is deemed to be impaired, a write-down of the value of the asset to its fair value may be required at such time. The Company reviews its finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Investment in Related Party

Investment in and advances to a related party in which the Company has a substantial ownership interest of approximately 20% to 50%, or for which the Company exercises significant influence but not control over policy decisions, are accounted for by the equity method. An investment in a limited liability company that is similar to a partnership is also accounted for under the equity method if more than minor influence over the operation of the investee exists (generally through more than 3-5% ownership). As part of that accounting, the Company recognizes gains and losses that arise from the issuance of stock by a related party that results in changes in the Company’s proportionate share of the dollar amount of the related party’s equity.

Investment in related party is assessed for possible impairment when events indicate that the fair value of the investment may be below the Company’s carrying value. When such a condition is deemed to be other than temporary, the carrying value of the investment is written down to its fair value, and the amount of the write-down is included in net loss. In making the determination as to whether a decline is other than temporary, the Company considers such factors as the duration and extent of the decline, the investee’s financial performance, and the Company’s ability and intention to retain its investment for a period that will be sufficient to allow for any anticipated recovery in the investment’s market value. The new cost basis of investments in these equity investees is not changed for subsequent recoveries in fair value.

As of June 30, 2020, the Company determined that other-than-temporary impairments in the full remaining carrying value of the investment in NantOmics have occurred (see Note 10). After the Company's equity method investment in NantOmics was reduced to zero, the Company no longer applies the equity method to record additional losses until NantOmics subsequently reports net income and that net income equals the share of net losses not recognized during the period the equity method was suspended.

Deferred Revenue

The Company records deferred revenue when it receives cash from customers prior to meeting the applicable revenue recognition criteria. The Company uses judgment in determining the period over which the deliverables are recognized as revenue. As of December 31, 2021 and 2020, current and non-current deferred revenue are comprised of deferrals for fees related to SaaS arrangements, technical support and maintenance, services and other revenue. Non-current deferred revenue as of December 31, 2021 is expected to be recognized in a period more than 12 months after that date.

Recently Adopted Accounting Pronouncements

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU') No. 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40). This update simplifies the accounting for convertible instruments by eliminating the cash conversion and beneficial conversion feature models which require separate accounting for embedded conversion features. This update also amends the guidance for the derivatives scope exception for contracts in an entity's own equity to reduce form-over-substance-based accounting conclusions and requires the application of the if-converted method for calculating diluted earnings per share. ASU No. 2020-06 is effective for fiscal periods beginning after December 15, 2023. The Company early adopted ASU 2020-06 on a modified retrospective basis on January 1, 2021. The cumulative effect of the adoption on accumulated deficit and additional paid-in capital was a decrease of $8,572 and $14,318, respectively, on January 1, 2021. Under the new guidance, the Company will record less noncash interest expense going forward as the cash conversion model that was previously applied is now eliminated.

Upcoming Accounting Standard Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which changes how companies measure credit losses on most financial instruments measured at amortized cost, such as loans, receivables and held-to-maturity debt securities. Rather than generally recognizing credit losses when it is probable that the loss has been incurred, the revised guidance requires companies to recognize an allowance for credit losses for the difference between the amortized cost basis of a financial instrument and the amount of amortized cost that the Company expects to collect over the instrument's contractual life. ASU No. 2016-13 is effective for fiscal periods beginning after December 15, 2022 and must be adopted as a cumulative effect adjustment to retained earnings. Early adoption is permitted. The Company is still evaluating the effects of this ASU.

Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants, and the SEC did not have, nor are believed by management to have, a material impact on the Company's present or future Consolidated Financial Statements.
