BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Consolidation —The consolidated financial statements include the accounts of Root, Inc. and its subsidiaries, all of which are wholly owned. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP. All intercompany accounts and transactions have been eliminated. To conform to the current year presentation, certain prior year amounts have been reclassified. Use of Estimates —The preparation of consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates reflected in our consolidated financial statements include, but are not limited to, reserves for loss and loss adjustment expense, or LAE, premium write-offs, fair value of warrants, intangible asset impairment and valuation allowance for income taxes. COVID-19 —In March 2020, the World Health Organization declared COVID-19 to be a global pandemic. The pandemic and related measures taken to contain the spread of COVID-19, such as government-mandated business closures, orders to “shelter in place” and travel and transportation restrictions, have negatively affected the U.S. and global economies, disrupted global supply chains, and led to unemployment. We, and other businesses within the insurance industry have been impacted by certain individual state bulletins that were issued in 2020 and outlined COVID-19-related premium relief efforts, including restrictions on the ability to cancel policies for non-payment, requirements to defer insurance premium payments for up to 60 days and restrictions on increasing policy premiums. The COVID-19 pandemic and governmental responses thereto have impacted and may further impact the broader economic environment, including creating or exacerbating supply chain disruptions and inflation and negatively impacting unemployment levels, economic growth, the proper functioning of financial and capital markets and interest rates. As a result of certain factors related to the COVID-19 global pandemic we continue to file in multiple states to establish rates that more closely follow the evolving loss cost trends. As the COVID-19 pandemic continues, there is uncertainty around the severity and duration of the pandemic and the pandemic’s potential impact on our business and our financial performance. Accordingly, we cannot predict the impact that it may have on our future results of operations and financial condition. Debt and Equity Issuance Costs —Debt and equity issuance costs, which primarily consist of advisor, legal, accounting, and other third-party fees directly related to issuing debt and equity instruments, are capitalized as other assets in our consolidated balance sheets as incurred. We incurred such costs in connection with our investment agreement we entered into with Carvana on August 21, 2021, or the Investment Agreement, and term loan agreement. Upon close of the related transaction, these deferred issuance costs are generally offset against the related proceeds. Debt issuance costs are subsequently amortized over the term of the financing agreement as interest expense on the consolidated statements of operations and comprehensive loss. Asset Acquisition —In November 2020, we acquired all of the authorized, issued and outstanding shares of Catlin Indemnity Company, renamed Root Property & Casualty, for $22.8 million, which included cash, cash equivalents, and accrued investment income of $14.4 million and insurance license indefinite-lived intangible assets of $8.4 million. The transaction costs associated with this acquisition were $0.5 million and were allocated to the insurance license indefinite-lived intangible assets acquired. This acquisition will expand our ability to sell personal auto insurance in 48 states and the District of Columbia. We accounted for the acquisition of Root Property & Casualty as an asset acquisition because substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets (the insurance licenses) and the acquisition of Root Property & Casualty did not include an input and a substantive process that together significantly contribute to the ability to create outputs and therefore does not meet the definition of a business under GAAP. Accordingly, we recognized the acquired assets at fair value as of the acquisition date, with transaction costs allocated to the insurance license indefinite-lived intangible assets. Indefinite-Lived Intangible Assets —In connection with the acquisition of Root Property & Casualty, we recognized insurance licenses of $8.9 million, including transaction costs, as of December 31, 2021 and 2020 in other assets in our consolidated balance sheets. We incur a minimal fee to renew each license. These intangible assets are not amortized, but instead are tested for impairment annually or when indicators of impairment exist. The impairment test for indefinite-lived intangibles involves first assessing qualitative factors to determine if it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. If so, then a quantitative test is performed to compare the estimated fair value of the indefinite-lived intangible asset to the respective asset's carrying amount. The evaluation requires the use of estimates and significant judgments and considers the weight of evidence and significance of all identified events and circumstances and most relevant drivers of fair value, both positive and negative, in determining whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount. No impairment was recognized for 2021 or 2020. Segment Information —Our chief operating decision maker is the Chief Executive Officer. The chief operating decision maker manages operations, allocates resources, and evaluates financial performance on a company-wide basis. We operate in one reporting segment providing direct-to-consumer insurance products to customers. Statement of Cash Flows —The supplemental disclosures for cash and non-cash flows for the years ended December 31, 2021, 2020 and 2019 are as follows: 2021 2020 2019 (in millions) Supplemental disclosures: Interest paid $ 23.9 $ 4.5 $ 4.3 Federal income taxes paid — — — Leasehold improvements - non-cash 1.5 — 1.5 Conversion of debt to preferred stock - non-cash — — 11.2 Conversion of preferred stock to common stock - non-cash — 560.4 — Conversion of warrants to common stock - non-cash — 75.0 — Lease liabilities arising from obtaining right-of-use asset 9.9 — — Investment Agreement issuance costs - non-cash 9.1 — — Purchases of treasury stock - non-cash — 0.5 — Cash, Cash Equivalents and Restricted Cash —Cash consists of cash on deposit. Cash equivalents are short-term, highly liquid investments that mature within three months from the date of origination and are principally stated at amortized cost, which approximates their fair value. Restricted cash consists of amounts held by a financial institution to satisfy letter of credit requirements for certain property leases. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amount in the consolidated statements of cash flows: 2021 2020 (in millions) Cash and cash equivalents $ 706.0 $ 1,112.8 Restricted cash 1.0 1.0 Total cash, cash equivalents and restricted cash shown in the statement of cash flows $ 707.0 $ 1,113.8 Book Overdraft —If checks are issued in excess of the amount of cash on hand, a book overdraft shall be reclassified to accounts payable on the consolidated balance sheets. When a check is issued whereby a disbursement account is used to write the check, but the account is not funded until the check is presented for payment this "negative cash" balance is included in cash and cash equivalents on the consolidated balance sheets, if the funding account has sufficient funds. Investments —Investments in debt securities are classified as short-term and available-for-sale securities and are carried at fair value with any unrealized gains and losses, net of taxes, recorded as a component of accumulated other comprehensive income. Management regularly reviews our securities for signs of impairment, an assessment requiring significant management judgment. Beginning with our adoption of Financial Accounting Standards Board, or FASB, Accounting Standard Update, or ASU, No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments as of January 1, 2021, the criteria that management considers are the financial condition of the issuer, including receipt of scheduled principal and interest cash flows, fair value of a security that has fallen below the amortized value, maturity dates, current economic conditions and intent to sell, including if it is more likely than not that we will be required to sell the security before recovery. We then assess whether the decline in value is due to non-credit related or credit related factors. Non-credit related declines in market value are recorded as unrealized losses in accumulated other comprehensive income. If we determine that the decline is credit related, we establish an allowance for credit losses equal to the difference between the discounted cash flow model and the amortized value, which is recorded in net realized gains (losses) on investments in our consolidated statements of operations and comprehensive loss. This allowance may be subsequently adjusted for recoveries or further credit losses. Prior to January 1, 2021, we were under an incurred loss model whereby we reviewed our securities for signs of other than temporary impairment. The criteria were similar to those noted above, except we also considered the length of time a security was in an unrealized loss position. When a debt security was determined to have an other than temporary impairment, the impairment charge was separated into an amount representing the credit loss, which would be recognized in earnings as a realized loss and the amount related to non-credit factors, which would be recognized in other comprehensive income. Subsequent recoveries of other than temporary impairment were not recognized. No such credit losses were recognized in 2021, nor were there other than temporary impairments recognized in 2020 or 2019. Other investments primarily consist of private equity investments without a readily determinable fair value. We elected to account for these investments at cost minus any impairment, plus or minus changes resulting from observable price changes in orderly transactions for an identical or a similar investment of the same issuer. Such changes are accounted for within net investment income on our consolidated statements of operations and comprehensive loss. We also invest in Low Income Housing Tax Credits, or LIHTC, projects by way of investing in a limited liability entity to offset Georgia premium taxes. The purpose of these investments is to encourage private capital investments into regions within Georgia that are in need of economic development, while providing tax credits and operating loss tax benefits to investors. We account for this investment using the cost method because our interest in the limited liability entity is so minor that we have virtually no influence over the entity’s operating and financial policies. When we utilize the tax credits, the associated investment becomes impaired. Impairment of the investment is recognized within net investment income in our consolidated statements of operations and comprehensive loss. Fair Value Measurements —Fair value is defined as the price that would be received upon selling an asset or the price paid to transfer a liability on the measurement date in the principal or most advantageous market for the asset or liability in an orderly transaction between willing market participants. A three-tier hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value. This hierarchy requires entities to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair values are: Level 1 - Financial assets and liabilities for which inputs are observable and are obtained from reliable quoted prices in active markets for identical assets and liabilities. Level 2 - Financial assets and liabilities for which values are based on quoted prices in markets that are not active or for which values are based on similar assets and liabilities that are actively traded. This also includes pricing models for which the inputs are corroborated by market data. Level 3 - Financial assets and liabilities for which values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Premiums, Premiums Receivable and Premium Write-offs —Premiums written are deferred and earned pro rata over the policy period. Unearned premium is established to cover the unexpired portion of premiums written. A premium deficiency, as measured on a gross basis, is recorded when the sum of expected losses, LAE, unamortized acquisition costs and maintenance costs exceed the recorded unearned premium reserve and anticipated investment income. A premium deficiency reserve is recognized as a reduction of deferred acquisition costs and, if necessary, by accruing an additional liability for the deficiency, with a corresponding charge to operations. We did not record a premium deficiency reserve in 2021, 2020 or 2019. In August 2021, we commenced a fronting arrangement with an unaffiliated Texas county mutual insurance company, or the fronting carrier. We route all of our new auto policies, and, over time, expect to route certain renewal auto policies, in Texas through the fronting carrier whereby we assume 100% of the related premium and losses on those policies. The fronting arrangement allows us to have greater rating and underwriting flexibility. Premiums assumed are deferred and earned pro rata over the policy period. Unearned premium is established to cover the unexpired portion of premiums assumed. Premiums receivable represents premiums written but not yet collected. Generally, premiums are collected prior to providing risk coverage, minimizing our exposure to credit risk. Due to a variety of factors, certain premiums billed may not be collected, for which we establish an allowance for doubtful accounts based primarily on an analysis of historical collection experience, adjusted for current economic conditions. Allowance for credit losses was $5.4 million and $3.5 million as of December 31, 2021 and 2020, respectively, on the consolidated balance sheets. A policy is considered past due on the first day after its due date and policies greater than 90 days past due are written-off. We recognized bad debt expense of $20.9 million, $23.6 million and $9.0 million for the years ended December 31, 2021, 2020 and 2019, respectively. Fee Income —Fee income consists of the flat fee we charge to those policyholders who pay premiums on an installment basis. The fee relates to the additional administrative costs associated with processing more frequent billings. We recognize this fee income in the period in which we process each installment. Other Income —Other income primarily comprises revenue earned from distributing website and app policy inquiry leads in geographies where we do not have a presence, recognized when we generate the lead; commissions earned for homeowners policies placed with third-party insurance companies where we have no exposure to the insured risk, recognized on the effective date of the associated policy; and sale of enterprise technology products to provide telematics-based data collection and trip tracking, recognized ratably as the service is performed. Sales and Marketing —Sales and marketing expenses includes spend related to performance and embedded channels, channel media, advertising, branding, public relations, consumer insights and referral fees. These expenses also include related employee costs including salaries, health benefits, bonuses, employee retirement plan related expenses and employee share-based compensation expense, or Personnel Costs, and overhead allocated based on headcount, or Overhead. It also includes warrant compensation expense related to our embedded channel. We incur sales and marketing expenses for all product offerings. Sales and marketing costs are expensed as incurred. Other Insurance Expense (Benefit) —Other insurance expense (benefit) includes underwriting expenses, credit card and policy processing expenses, premium write-offs, insurance license expenses, and Personnel Costs and Overhead related to actuarial and certain data science activities. Other insurance expense (benefit) also includes amortization of deferred acquisition costs like premium taxes and report costs related to the successful acquisition of a policy. Other insurance expense (benefit) is expensed as incurred, except for costs related to deferred acquisition costs that are capitalized and subsequently amortized over the same period in which the related premiums are earned. These expenses are also recognized net of ceding commissions earned from our quota share reinsurance agreements. The ceding commission provides for reimbursement of both direct and other periodic acquisition costs, including certain underwriting and marketing costs, and is presented as a reduction of other insurance expense (benefit). Technology and development —Technology and development expense consists of software development costs related to our mobile app and homegrown information technology systems; third-party services related to infrastructure support; Personnel Costs and Overhead for engineering, product, technology, and certain data science activities; and amortization of internally developed software. Technology and development is expensed as incurred, except for development and testing costs related to internally developed software that are capitalized and subsequently amortized over the expected useful life. General and Administrative —General and administrative expenses primarily relate to external professional service expenses; Personnel Costs and Overhead for corporate functions; and depreciation expense for computers, furniture and other fixed assets. General and administrative expenses are expensed as incurred. Policy Acquisition Costs —Acquisition costs consist primarily of premium taxes, certain marketing costs and underwriting expenses, and fronting carrier commissions, net of ceding commissions, related to the successful acquisition of new or renewal business. They are deferred and amortized over the same period in which the related premiums are earned. Ceding commissions relating to reinsurance agreements are recorded as a reimbursement for both deferrable and non-deferrable acquisition costs. The portion of the ceding commission that is equal to the pro rata share of acquisition costs based on quota share percentage is recorded as an offset to the gross deferred acquisition costs. Any portion of the ceding commission that exceeds the acquisition costs of the business ceded is recorded as excess ceding commission, a deferred liability, and amortized over the same period in which the related premiums are earned. Deferred acquisition costs, net of accumulated amortization, was $2.8 million and $1.7 million as of December 31, 2021 and 2020, respectively.We amortized deferred acquisition costs of $26.4 million, $17.1 million and $12.2 million for the years ended December 31, 2021, 2020 and 2019, respectively. Loss and Loss Adjustment Expense and Reserves —Loss and LAE reserves include an amount determined using adjuster determined case-base estimates for reported claims and actuarial determined unpaid claim estimates using past experience and historical emergence patterns for unreported losses and LAE. These reserves are a liability established to cover the estimated ultimate cost to settle insured losses. The estimation of the liability for loss and LAE reserves is complex and includes subjective considerations and management’s judgement. The actuarial methods to determine unpaid loss es timates consider loss trends, contract interpretation, mix of business, regulatory environment, economic conditions, inflation and other risk factors impacting claims settlement. The method used to estimate unpaid LAE liability is based on claims transaction data, including the relative cost of adjusting and settling a range of claim types from express material damage claims to more complex injury cases. There is considerable uncertainty associated with the actuarial estimates, and therefore no assurance can be made that the ultimate unpaid claim liability will not vary materially from such estimates. These loss estimates are continually reviewed by management and adjusted as necessary, with adjustments included in the period determined and recorded in loss and LAE on our consolidated statements of operations and comprehensive loss. As such, loss and LAE reserves represent management’s best estimate of the ultimate liability related to reported and unreported claims. Our loss and LAE reserves are recorded gross of reinsurance and net of amounts expected to be received from salvage (the amount recovered from a total loss claims expense) and subrogation (the right to recover payments from third parties). Loss and LAE is recorded net of amounts ceded to reinsurers. We enter into reinsurance contracts to limit our exposure to potential losses as well as to provide additional capacity for growth. These expenses are a function of the size and term of the insurance policies we write and the loss experience associated with the underlying risks. Loss and LAE may be paid out over a period of years. Various other expenses incurred during claims processing are allocated to LAE. These amounts include claims Personnel Costs, software expense, internally developed software amortization, and Overhead. Reinsurance —In the ordinary course of business, we cede and retrocede a portion of our business written and assumed, respectively, to reinsurers to limit the maximum net loss potential arising from large risks and catastrophes. These arrangements, known as treaties, provide for reinsurance coverage on quota-share and excess-of-loss basis. All reinsurance contracts provide for indemnification against loss or liability relating to insurance risk and have been accounted for as reinsurance. Although the ceding of reinsurance does not discharge us from our primary liability to the policyholder, the insurance company that assumes the coverage assumes the related liability. Amounts recoverable from and payable to reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured business. Reinsurance premiums, commissions and expense reimbursements related to reinsured business are accounted for on a basis consistent with the basis used in accounting for the original policies issued and the terms of the reinsurance contracts. Premiums ceded to other companies have been reported as a reduction of premiums earned and are recognized over the remaining policy period based on the reinsurance protection provided. Amounts applicable to reinsurance ceded for unearned premium reserves are reported as a prepaid reinsurance premiums asset in the accompanying consolidated balance sheets and as reduction of unearned premiums in Note 6, “Reinsurance.” Ceding commissions received in connection with reinsurance ceded have been accounted for as a reduction of other insurance (benefit) expense in the consolidated statements of operations and comprehensive loss. Some of our reinsurance agreements provide for adjustment of commissions or amount of coverage based on loss experience. We recognize the asset or liability arising from these adjustable features in the period the adjustment occurs, which is calculated based on experience to-date under the agreement. In the event that all or any of the reinsuring companies might be unable to meet their obligations under existing reinsurance agreements, we would be liable for such defaulted amounts. We evaluate and monitor the financial condition associated with our reinsurers in order to minimize our exposure to significant losses from reinsurer insolvencies. We obtain our reinsurance from a diverse group of reinsurers and monitor concentration as well as financial strength ratings of the reinsurers to minimize counterparty credit risk. To recognize this risk of credit loss, we have established an allowance for credit losses based on the probability of default and the expected loss given default as influenced by factors such as the reinsurer’s credit rating and average life of our reinsurance recoverables. Allowance for credit losses was $0.2 million and zero as of December 31, 2021 and 2020, respectively. Income Taxes —For the 2021 tax year, Root, Inc. will file a consolidated federal income tax return with Caret Holdings, Inc., Root Insurance Company, Root Property & Casualty, Root Lone Star Insurance Agency, Inc, and Root Reinsurance Company, Ltd. The consolidated return also includes Root Insurance Agency, LLC, Root Enterprise, LLC and Root Scout, LLC, which are disregarded entities under Caret Holdings, Inc. for federal income tax purposes. Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Deferred tax assets are recognized to the extent that there is sufficient positive evidence, as allowed under the Accounting Standard Codification, or ASC, 740, Income Taxes , to support the recoverability of those deferred tax assets. We establish a valuation allowance to the extent that there is insufficient evidence to support the recoverability of the deferred tax asset under ASC 740. In making such a determination, management considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and results of recent operations. If it is determined that the deferred tax assets would be realizable in the future in excess of their net recorded amount, an adjustment would be made to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. A valuation allowance of $255.0 million and $137.3 million was established as of December 31, 2021 and 2020, respectively. Further details are discussed in Note 9, "Income Taxes." We recognize the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained under examination by the appropriate taxing authority. Interest and penalties on our reserve for uncertain tax positions are recognized as a component of tax expense. As of December 31, 2021 and 2020, we did not have any unrecognized tax benefits for uncertain tax positions and had no accrued interest or penalties related to uncertain tax positions. Internally Developed Software —We review our software development activity and capitalize costs during the application development phase under ASC 350-40, Internal-Use Software. These costs are amortized on a straight-line basis over a five-year period. Internally developed software costs are assessed for impairment at least quarterly, which also ensures that the assets are still in service. If there are assets identified as no longer in use, the remaining unamortized costs will be fully amortized. We amortized internally developed software of $3.7 million, $2.4 million and $1.4 million for the years ended December 31, 2021, 2020 and 2019, respectively. The capitalized cost and accumulated amortization of internally developed software at December 31, 2021 and 2020 are as follows: 2021 2020 (dollars in millions) Internally developed software $ 20.5 $ 13.9 Accumulated amortization (8.0) (4.3) Internally developed software, net $ 12.5 $ 9.6 Fixed Assets —Fixed Assets are carried at cost, net of accumulated depreciation. We capitalize purchases of fixed assets with costs greater than $1,000, including computers, furniture, and leasehold improvements. Depreciation on computers and furniture is recognized on a straight-line basis over a useful life of three years and five years, respectively. Depreciation on leasehold improvements is recognized on a straight-line basis over the shorter of their useful life or the life of the lease. When certain events or changes in operating conditions occur, an impairment assessment may be performed on the recoverability of the carrying amounts. For the years ended December 31, 2021, 2020 and 2019, depreciation expense was $4.6 million, $3.1 million and $1.7 million, respectively. The capitalized cost and accumulated depreciation of fixed assets at December 31, 2021 and 2020 are as follows: 2021 2020 (dollars in millions) Computers $ 7.0 $ 4.5 Furniture 3.4 3.4 Leasehold improvements 9.8 6.3 Total fixed assets, at cost $ 20.2 $ 14.2 Accumulated depreciation (9.9) (5.3) Fixed assets, net $ 10.3 $ 8.9 Employee Share-Based Compensation —We award share-based compensation, including stock options with only a service condition, stock options with service and performance conditions, restricted stock units, or RSUs, and restricted stock, to our officers, directors, employees, and certain advisors through approval from the Compensation Committee of the Board of Directors. We have also granted warrants to purchase shares of the Company’s Class A common stock to Carvana, which vest based upon achievement of certain performance conditions. Share-based compensation expense is recognized based on the grant date fair value of the awards, which is determined using the Black-Scholes Merton, or BSM, option-pricing model. The BSM option pricing model requires inputs based on certain subjective assumptions, including the expected stock price volatility, the expected term of the options, the risk-free interest rate for a period that approximates the expected term of the option, and our expected dividend yield. The fair value of common stock underlying the stock options, restricted stock and RSUs granted before our initial public offering, or IPO, had historically been determined by our Board of Directors, with input from management, and considering third-party valuations of our common stock. Because there had been no public market for our common stock, our Board of Directors had determined its fair value at the time of grant of the pre-IPO option by considering a number of objective and subjective factors, including financing investment rounds, operating and financial performance, the lack of liquidity of share capital and general and industry specific economic outlook, among other factors. Our Board of Directors determined the fair value of common stock based on valuations performed using the Option Pricing Method and the Probability Weighted Expected Return Method subject to relevant facts and circumstances. In connection with our IPO, our common stock became listed on the Nasdaq Global Select Market and we use these market prices for the fair value of our common shares. Stock options are generally exercisable for a period up to ten years from the grant date. We recognize forfeitures as they occur, which generally results in the reversal of previously recognized expense for nonvested awards. In the event of |
