Summary of Operations and Basis of Presentation
Summary of Operations and Basis of Presentation	1. Summary of Operations and Basis of Presentation Summary of Operations Palomar Holdings, Inc. (“the Company”) is a Delaware incorporated insurance holding company that was founded in 2014. The Company has several wholly owned subsidiaries including an Oregon domiciled insurance company, Palomar Specialty Insurance Company (“PSIC”), a Bermuda based reinsurance company, Palomar Specialty Reinsurance Company Bermuda Ltd. (“PSRE”), an Arizona domiciled surplus lines insurance company, Palomar Excess and Surplus Insurance Company (“PESIC”), and a California domiciled property and casualty insurance agency, Palomar Insurance Agency, DBA Palomar General Insurance Agency (“PGIA”). PSIC is a property and casualty insurance company domiciled in the state of Oregon. The Company’s core focus is on the residential and commercial earthquake markets in earthquake‑exposed states such as California, Oregon, Washington, and states with exposure to the New Madrid Seismic Zone. The Company also offers products tailored to broader geographic regions and perils, including Hawaii residential hurricane, Specialty Homeowners, Inland Marine, and Flood products. PSIC is licensed to underwrite insurance on an admitted basis in 32 states in the United States, as of December 31, 2020, mainly through managing general insurance agencies, wholesale brokers, and independent agents. PSRE is a Bermuda captive reinsurance company that has historically been used to reinsure certain premiums on a quota share basis exclusively for PSIC. PESIC is an Arizona domiciled surplus lines insurance company. PESIC is licensed in Arizona to write surplus lines policies across all the Company’s lines of business and was formed and began writing policies in 2020. PGIA is a property and casualty general insurance agency for PSIC, PESIC, and unaffiliated insurance carriers. As a general insurance agency, PGIA assists in developing insurance products, underwriting insurance policies, and receiving and disbursing funds from premium and loss transactions under contracts on behalf of insurance companies. PGIA earns commissions from the product development, marketing, and servicing of the insurance companies’ programs. PGIA also earns fee income from policyholder transactions. The Company operates as an insurance holding company system and is subject to the insurance holding company laws of the States of Oregon and Arizona, the states in which PSIC and PESIC are domiciled. The Company is also commercially domiciled in California, making it subject to California insurance holding company laws. These statutes require that each insurance company in the system register with the insurance department of its state of domicile and furnish information concerning the operations of companies within the holding company system that may materially affect the operations, management or financial condition of the insurers within the system and domiciled in that state. The Company has a single operating segment, the property and casualty insurance business. While the Company’s chief operating decision‑maker reviews the revenue streams attributable to individual products, operations are managed, resources are allocated, and financial performance is evaluated on a consolidated basis. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of the Company and its wholly‑owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Stock Split On March 15, 2019, the Company effected a 17,000,000 for one forward stock split in conjunction with domestication in the United States. All share and per share information included in the accompanying consolidated financial statements and notes to the consolidated financial statements have been retroactively adjusted to reflect the stock split for the Company’s common stock for all periods presented. Initial Public Offering (“IPO”) On April 22, 2019, the Company completed its IPO with the sale of 6,468,750 shares of common stock at a price to the public of $15.00 per share, including 843,750 shares sold upon the exercise in full of the underwriter’s option to purchase additional shares. After underwriter discounts and commissions and offering expenses, net proceeds from the IPO were approximately $87.4 million. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein. All revisions to accounting estimates are recognized in the period in which the estimates are revised. Significant estimates reflected in the Company’s consolidated financial statements include, but are not limited to, reserves for losses and loss adjustment expenses, reinsurance recoverables on unpaid losses, and the fair values of investments.

Significant Accounting Policies

Significant Accounting Policies	12 Months Ended
	Dec. 31, 2020
Significant Accounting Policies
Significant Accounting Policies	2. Significant Accounting Policies Cash and Cash Equivalents Cash and cash equivalents include time deposits and marketable securities with original maturities of three months or less at acquisition and are stated at cost, which approximates fair value. The Company maintains cash balances in federally insured financial institutions. Restricted Cash Restricted cash includes cash on deposit with reinsurance carriers. Restricted cash also includes cash held in a fiduciary capacity for the benefit of third-party insurance carriers. Investments All of the Company’s investments in fixed maturity securities are classified as available‑for‑sale and are carried at fair value. Investment income consists primarily of interest and dividends. Interest income is recognized on an accrual basis. Premiums and discounts on mortgage‑backed securities and asset‑backed securities are amortized or accrued using the prospective method which considers anticipated prepayments at the date of purchase. To the extent that the estimated lives of such securities change as a result of changes in estimated prepayment rates, the adjustments are included in net investment income using the prospective method. Dividend income is recognized on the ex‑dividend date. Net investment income represents investment income, net of expenses. Unrealized gains and losses related to fixed maturity securities are included in accumulated other comprehensive income as a separate component of stockholders’ equity. Equity securities are carried at fair value with unrealized gains and losses included as a component of net income on the Company’s consolidated statement of income and comprehensive income. The Company uses the specific‑identification method to determine the cost of fixed maturity securities sold and the first‑in, first‑out method for lots of equity securities sold. The Company reviews all securities with unrealized losses on a quarterly basis to assess whether the decline in the securities fair value necessitates the recognition of an allowance for credit losses. Factors considered in the review include the extent to which the fair value has been less than amortized cost, and current market interest rates and whether the unrealized loss is credit‑driven or a result of changes in market interest rates. The Company also considers factors specific to the issuer including the general financial condition of the issuer, the issuers industry and future business prospects, any past failure of issuer to make scheduled interest or principal payments, and the payment structure of the investment and the issuers ability to make contractual payments on the investment. The Company also considers whether it intends to sell the security or if it is more likely than not that it will be required to sell the security before recovery of its amortized cost. When assessing whether it intends to sell a fixed-maturity security or if it is likely to be required to sell a fixed-maturity security before recovery of its amortized cost, the Company evaluates facts and circumstances including, but not limited to, decisions to reposition the investment portfolio, potential sales of investments to meet cash flow needs, and potential sales of investments to capitalize on favorable pricing. For fixed-maturity securities where a decline in fair value is below the amortized cost basis and the Company intends to sell the security, or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, a credit-loss charge is recognized in net income based on the fair value of the security at the time of assessment. For fixed-maturity securities that the Company has the intent and ability to hold, the Company compares the estimated present value of the cash flows expected to be collected to the amortized cost of the security. The extent to which the estimated present value of the cash flows expected to be collected is less than the amortized cost of the security represents the credit-related portion of the impairment, which is recognized in net income through an allowance for credit losses. Any remaining decline in fair value represents the noncredit portion of the impairment, which is recognized in other comprehensive income. The Company reports accrued interest receivable as a component of accrued investment income on its consolidated balance sheet which is presented separately from available-for-sale securities. The Company does not measure an allowance for credit losses on accrued interest receivable and instead would write off accrued interest receivable at the time an issuer defaults or is expected to default on payments. Prior to the adoption of ASU 2016-13, the Company evaluated fixed maturity securities for credit losses and any losses were bifurcated into the credit‑related loss and the loss related to all other factors. The credit‑related impairment loss would have been recognized as a realized loss in the statement of income and comprehensive income and the cost basis of the security would have been reduced. The impairment related to other factors would have remained in accumulated other comprehensive income. The Company did not recognize any credit losses during the years ended December 31, 2020 and 2019 related to its available-for-sale securities. Fair Value Fair value is defined as the price that the Company would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. The three‑tier hierarchy of inputs is summarized in the three broad levels listed below: Level 1—Unadjusted quoted prices are available in active markets for identical investments as of the reporting date. Level 2—Pricing inputs are quoted prices for similar investments in active markets; quoted prices for identical or similar investments in inactive markets; or valuation based on models where the significant inputs are observable or can be corroborated by observable market data. Level 3—Pricing inputs into models are unobservable for the investment. The unobservable inputs require significant management judgment or estimation. To measure fair value, the Company obtains quoted market prices for its investment securities from its outside investment managers. If a quoted market price is not available, the Company uses prices of similar securities. The fair values obtained from the outside investment managers are reviewed for reasonableness and any discrepancies are investigated for final valuation. The fair value of the Company’s investments in fixed maturity securities is estimated using relevant inputs, including available market information, benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. An Option Adjusted Spread model is also used to develop prepayment and interest rate scenarios. Industry standard models are used to analyze and value securities with embedded options or prepayment sensitivities. These fair value measurements are estimated based on observable, objectively verifiable market information rather than market quotes; therefore, these investments are classified and disclosed in Level 2 of the hierarchy. The fair value of the Company’s investments in equity securities is based on quoted prices available in active markets and classified and disclosed in Level 1 of the hierarchy. Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, fixed maturity securities and reinsurance recoverables. The Company places its cash and cash equivalents with high credit quality financial institutions and its fixed maturity securities in securities of the U.S. government, U.S. government agencies, and high credit quality issuers of debt securities. The Company evaluates the financial condition of its reinsurers and reinsures its business with highly rated reinsurers and sometimes requires letters of credit or retains funds from reinsurers (see Note 10). Premiums Receivable Premiums receivable represent amounts due from policyholders, insurance agents, or program administrators for policies written. Generally, premiums are collected prior to providing risk coverage, minimizing the Company’s exposure to credit risk. Premiums receivable are short-term in nature and due within a year. The Company has established an allowance for uncollectable premiums related to its credit risk, which it reviews on a quarterly basis and adjusts as appropriate. The company considers the current economic environment, specific regulatory developments, and historic payment and cancelation trends by line of business and location when determining whether to record an allowance for uncollectable premiums. Prior to December 31, 2019, the Company did not have an allowance for uncollectable premiums. An initial allowance for uncollectable premiums of $0.2 million was established upon adoption of ASC 2016-13 on January 1, 2020 and the company recognized an immaterial amount of credit losses relating to uncollectable premiums during the year ended December 31, 2020. Deferred Policy Acquisition Costs The costs of successfully acquiring new business, principally commission expense and premium taxes, are deferred and amortized over the terms of the policies in force, net of any ceding commissions. Premiums Earned Gross premiums written are recorded at policy inception and are earned as revenue ratably over the term of the respective policies. Premiums written not yet recognized as revenue are reflected as unearned premiums on the balance sheet, or as advanced premiums if received prior to the policy effective date. Premiums written where cash is not yet received are recognized as premiums receivable. A premium deficiency is recognized if the sum of expected losses and loss adjustment expenses, unamortized acquisition costs, and policy maintenance costs exceeds the remaining unearned premiums. A premium deficiency would first be recognized by charging any unamortized acquisition costs to expense to the extent required to eliminate the deficiency. If the premium deficiency were greater than unamortized acquisition costs, a liability would be accrued for the excess deficiency. The Company does not consider anticipated investment income when determining if a premium deficiency exists. There was no premium deficiency at December 31, 2020 or 2019. Commission and Other Income Commission and other income is comprised of commissions earned on policies where the Company has no exposure to underlying risk and fees earned in conjunction with underwriting policies. Commission and fee income is earned at the time the policy is written. Property and Equipment Property and equipment are capitalized and carried at cost less accumulated depreciation. Depreciation for property and equipment is calculated on a straight‑line basis using useful lives of 3 to 5 years. Leasehold improvements and other fixed assets are capitalized and depreciated over the useful lives of the properties and equipment. Expenditures for maintenance and repairs are charged to operations as incurred. Upon disposition, the asset cost and related depreciation are removed from the accounts and the resulting gain or loss is included in the Company’s results of operations. Capitalized Software Costs associated with the implementation of certain internal systems are capitalized and carried at capitalized cost less accumulated amortization and are included as a component of prepaid expenses and other assets on the Company’s consolidated balance sheet. Costs capitalized include internal personnel costs, external developer costs, and interest. The implementation costs relate to systems built on software which the Company purchases under a cloud computing arrangement and accounts for as a service contract. As such, capitalized costs are amortized over the term of the service contract, which currently ends in December 2024. Intangible Assets Intangible assets consist of both finite and indefinite lived assets. Finite lived intangible assets consist of customer relationships acquired from another insurer during 2020. Indefinite lived intangible assets consist of state licenses acquired upon formation of the Company. Intangible assets are initially recognized and measured at fair value and are subsequently evaluated for impairment annually or more frequently if circumstances warrant it. No impairments of intangible assets were recognized for the years ended December 31, 2020, 2019 or 2018. Impairment of Long‑Lived Assets Long‑lived assets with finite lives are tested for impairment whenever recognized events or changes in circumstances indicate the carrying value of these assets may not be recoverable. If indicators of impairment are present, the fair value is calculated using estimated future cash flows expected to be generated from the use of those assets. An impairment loss is recognized only if the carrying amount of a long‑lived asset or asset group is not recoverable and exceeds its fair value. The carrying amount of a long‑lived asset or asset group is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group. This assessment is based on the carrying amount of the asset or asset group at the date it is tested for recoverability. An impairment loss is measured as the amount by which the carrying amount of a long‑lived asset or asset group exceeds its fair value. No impairments of long‑lived assets were recognized for the years ended December 31, 2020, 2019 and 2018. Reserve for Losses and Loss Adjustment Expenses The reserve for unpaid losses and loss adjustment expenses includes estimates for unpaid claims and claim adjustment expenses on reported losses and estimates of losses incurred but not reported (“IBNR”), net of salvage and subrogation recoveries. The liability is based on individual claims, case reserves and other estimates reported by policyholders, as well as management estimates of ultimate losses and loss adjustment expenses. Inherent in the estimates of ultimate losses and loss adjustment expenses are expected trends in claims severity and frequency and other factors that could vary significantly as claims are settled. The Company’s estimates of ultimate losses and loss adjustment expenses are based in part upon the estimation of claims resulting from natural disasters such as hurricanes and earthquakes. Estimation by management of the ultimate losses and loss adjustment expenses resulting from catastrophic events is inherently difficult because of the potential severity of property catastrophe claims. Therefore, the Company uses both proprietary and commercially available models, as well as historic claims experience, for purposes of providing an estimate of ultimate losses and loss adjustment expenses. Reserves for IBNR are established in accordance with industry practice to provide for (i) the estimated amount of future loss payments on incurred claims not yet reported, and (ii) potential development on reported claims. IBNR reserves are estimated based on generally accepted actuarial reserving techniques that consider quantitative loss experience data and, where appropriate, qualitative factors. Ultimate losses and loss adjustment expenses may vary materially from the amounts provided in the consolidated financial statements. Estimates of unpaid losses and loss adjustment expenses are reviewed regularly and, as experience develops and new information becomes known, the liabilities are adjusted as necessary. Such adjustments, if any, are reflected in operations in the period in which they become known and are accounted for as changes in estimates. The Company does not discount its liability for unpaid losses and loss adjustment expenses. The Company does not write insurance policies covering toxic clean‑up, asbestos‑related illness or other environmental remediation exposures. Reinsurance The Company purchases excess of loss and quota share reinsurance to protect it against the impact of losses. Reinsurance premiums, commissions, ceded unearned premiums are accounted for on bases consistent with the underlying terms of the reinsurance contracts and in proportion to the amount of insurance protection provided. The Company receives ceding commissions in connection with quota share reinsurance. The ceding commissions are capitalized and amortized as a reduction of acquisition expenses. Amounts applicable to ceded unearned premiums are reported as assets in the accompanying consolidated balance sheets. Premiums earned and losses and loss adjustment expenses incurred are stated in the accompanying consolidated statements of income and comprehensive income net of amounts ceded to reinsurers. Reinsurance recoverables represent balances due to the Company from its reinsurers for paid and unpaid losses and loss adjustment expenses. The Company is exposed to credit losses from reinsurers being unable to meet their obligations. The Company evaluates the financial condition of potential reinsurers and reinsures its business only with highly rated reinsurers with a rating of “A-“ (Excellent) (Outlook Stable) or better from A.M. Best. Reinsurers who do not meet the Company’s rating criteria are required to post collateral. The Company reviews credit quality of its reinsurers on a quarterly basis. The Company’s reinsurance contracts also include special termination provisions that allow the Company to cancel and replace any participating reinsurer that is downgraded below a rating of “A−” from A.M. Best, or whose surplus drops by more than 20%. Historically, the Company has not experienced any credit losses from reinsurance recoverables and did not have an allowance for uncollectable reinsurance recoverables as of December 31, 2020 or December 31, 2019. Stock Based Compensation Expense Stock-based compensation expense is recognized on a straight-line basis over the vesting period of awards. The Company does not apply a forfeiture rate to unvested awards and accounts for forfeitures as they occur. For stock option grants, the fair value of awards is estimated using the Black Scholes Model. The fair value of restricted stock units is determined using the closing price of the Company's common stock on the grant date. All stock-based compensation is included in other underwriting expenses in the Company’s consolidated statements of income and comprehensive income. Income Taxes The Company is taxed as a property/casualty insurer for federal income tax purposes. Deferred income tax assets and liabilities are determined based on the difference between the financial statement and the tax bases of assets and liabilities, using enacted tax rates expected to be in effect during the year in which the basis differences reverse. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. The Company recognizes the tax benefit of uncertain tax positions where the position is more likely than not to be sustained assuming examination by taxing authorities. Based on its evaluation for the tax years ended December 31, 2020 and 2019, the Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. The Company recognizes interest and penalties related to uncertain tax positions, if any, as a component of income tax expense. The Company has not been assessed interest or penalties by any major tax jurisdictions for the respective tax years ended December 31, 2020, 2019, and 2018. Earnings Per Share Basic earnings per share is calculated by dividing net income by the weighted‑average common shares outstanding for the period. Diluted earnings per share reflects the dilution which could occur if equity-based awards are converted into common share equivalents as calculated using the treasury stock method. When inclusion of additional common share equivalents increases the earnings per share or reduces the loss per share, the effect on earnings per share is anti-dilutive, and the diluted net earnings or net loss per share is computed excluding these common share equivalents. Recently adopted accounting pronouncements Clarification on change in filing status and prior quarterly information Prior to December 31, 2020, the Company qualified as an emerging growth company (“EGC”) under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. The Company was previously electing to adopt new or revised accounting guidance within the same time periods as private companies as permitted by its status as an EGC. The Company became a large accelerated filed on December 31, 2020 and must now adopt new accounting guidance within the same time periods as public companies, beginning with this 2020 Annual Report on Form 10-K. Prior to this annual report, the Company’s 2020 quarterly filings did not reflect adoption of the below guidance as the Company was not required to have adopted it. Upon adoption of the below guidance, the Company updated its financials as if the below guidance was adopted on January 1, 2020, however, this adoption had a negligible impact on previously filed quarterly information. Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued new guidance for accounting for leases, ASU 2016‑02, Leases (Topic 842) and subsequently issued multiple clarifying updates to the guidance. This updated guidance requires the recognition of a right‑of‑use (“ROU”) asset and a corresponding lease liability, discounted to the present value, for all leases that extend beyond 12 months. Under the previous guidance, leases were only included on the balance sheet if the criteria to classify the agreement as a capital lease were met. The Company adopted this new guidance as of January 1, 2020. The Company adopted this guidance using the modified retrospective transition method, applying the transition provisions on the date of adoption and not restating prior periods. The Company elected to use a number of practical expedients permitted under the transition guidance, but did not elect to use hindsight in determining the lease term. Upon adoption, the Company recognized a ROU asset of $2.9 million and lease liabilities of $3.8 million, with the difference representing the reclassification of deferred rent and lease incentive liabilities (the difference between the straight-line rent expenses and cash paid for rent under the leases) to operating lease ROU assets from other liabilities. The ROU asset and corresponding liability recognized pertained to various operating leases for office space. The Company did not have any cumulative-effect adjustment because of the adoption. Measurement of credit losses In June 2016, the FASB issued ASU 2016‑13, Financial Instruments-Credit Losses (Topic 326) and subsequently issued multiple clarifying updates to the guidance. This updated guidance requires financial assets measured at amortized cost to be presented at the net amount expected to be collected by means of an allowance for credit losses that is included in net income. Credit losses relating to available-for-sale debt securities are also required to be recorded through a reversible allowance for credit losses, but the allowance is limited to the amount by which fair value is less than amortized cost. The previous accounting guidance delayed the recognition of credit losses until it was probable a loss had been incurred. The Company adopted this guidance on January 1, 2020 using the modified retrospective approach and recorded a $0.2 million cumulative effect adjustment to beginning retained earnings upon adoption relating to an allowance for credit losses on the Company’s premium receivables. The adoption of this accounting guidance did not have an impact on value of the Company’s fixed maturity securities or its reinsurance recoverables. Recently issued accounting pronouncements not yet adopted Income Taxes In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. Among other things, ASU 2019-12 eliminates certain exceptions for recognizing deferred taxes for investments, performing intra-period tax allocation and calculating income taxes in interim periods. ASU 2019-12 also clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company will adopt this guidance in the first fiscal quarter of 2021 and does not expect adoption to have a material impact on its consolidated financial statements.

None of the fixed maturity securities with unrealized losses has ever missed, or been delinquent on, a scheduled principal or interest payment. As of December 31, 2019, the Company held 51 fixed maturity securities in an unrealized loss position with a total estimated fair value of $20.9 million and total gross unrealized losses of $0.1 million. None of the fixed maturity securities with unrealized losses has ever missed, or been delinquent on, a scheduled principal or interest payment. The aggregate fair value and gross unrealized losses of the Company’s investments aggregated by investment category and the length of time these individual securities have been in a continuous unrealized loss position as of December 31, 2020 and 2019, are as follows: Less Than 12 Months More Than 12 Months Total Fair Unrealized Fair Unrealized Fair Unrealized December 31, 2020 Value Losses Value Losses Value Losses (in thousands) Fixed maturity securities: U.S. Governments $ 1,496 $ (5) $ — $ — $ 1,496 $ (5) States, territories, and possessions — — — — — — Political subdivisions — — — — — — Special revenue excluding mortgage/asset-backed securities 520 (2) — — 520 (2) Industrial and miscellaneous 22,718 (234) 203 (57) 22,921 (291) Mortgage/asset-backed securities 16,092 (211) 496 (4) 16,588 (215) Total $ 40,826 $ (452) $ 699 $ (61) $ 41,525 $ (513) Less Than 12 Months More Than 12 Months Total Fair Unrealized Fair Unrealized Fair Unrealized December 31, 2019 Value Losses Value Losses Value Losses (in thousands) Fixed maturity securities: U.S. Governments $ 1,235 $ (11) $ 1,827 $ (2) $ 3,062 $ (13) States, territories, and possessions — — — — — — Political subdivisions — — — — — — Special revenue excluding mortgage/asset-backed securities 3,548 (46) — — 3,548 (46) Industrial and miscellaneous 6,929 (38) 188 (1) 7,117 (39) Mortgage/asset-backed securities 7,035 (19) 182 — 7,217 (19) Total $ 18,747 $ (114) $ 2,197 $ (3) $ 20,944 $ (117) The Company reviewed the above securities at each balance sheet date to consider whether it was necessary to recognize a credit loss or other-than-temporary impairment (OTTI) related to any of these securities. Based on the reviews, the company determined that the fixed maturity securities’ unrealized losses were primarily the result of the interest rate environment and not the credit quality of the issuers for both periods. The Company does not intend to sell the investments and it is not more likely than not that that the Company will be required to sell the investments before the recovery of their amortized cost basis. Therefore, the Company did not recognize an allowance for credit losses related to any of these securities for the year ended December 31, 2020 and did not recognize any OTTI charges for the year ended December 31, 2019. Contractual maturities of available‑for‑sale fixed maturity securities The amortized cost and fair value of fixed maturity securities at December 31, 2020, by contractual maturity, are shown below.

These securities are included in available‑for‑sale investments on the consolidated balance sheets. At December 31, 2020 and 2019, the carrying value of securities on deposit with state regulatory authorities was $7.5 million and $5.1 million, respectively.

Leases	8. Leases The Company has operating leases for office space used to conduct its insurance operations and administration activities. Operating lease ROU assets are a component of prepaid expenses and other assets and operating lease liabilities are included in accounts payable and other accrued liabilities in the Company's consolidated balance sheets. The Company determines whether an arrangement is a lease at its inception. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. To determine the present value of lease payments, the Company uses its incremental borrowing rate, which it calculates based on information available at the lease commencement date. For certain leases that contain options to extend, the options are included in lease liabilities only if the company is reasonably certain the option will be exercised. Variable lease costs such as parking are expensed in the period the obligation is incurred and are not included in the Company’s operating lease liability. The Company's lease agreements do not contain any residual value guarantees. Operating lease costs for the years ended December 31, 2020, 2019 and 2018 were $0.7 million, $0.6 million and $0.6 million, respectively. Operating lease costs are comprised of rental expense for operating leases. Lease expense is recognized on a straight-line basis over the lease term and is included as a component of other underwriting expenses in the Company’s consolidated statements of income and comprehensive income. The following tables provide supplementary information about the Company’s leases: Year ended December 31, 2020 (in thousands) Operating cash outflows from operating leases $ 842 Right of use assets obtained in exchange for new operating lease liabilities — December 31, 2020 ($ in thousands) Operating lease ROU assets $ 2,274 Operating lease liabilities $ 3,012 Weighted-average remaining lease term-operating leases years Weighted-average discount rate-operating leases % Future minimum lease payments as of December 31, 2020 are as follows: Years ending December 31, (in thousands) 2021 $ 2022 2023 2024 2025 — Total future minimum lease payments $ 3,123 Less: imputed interest (111) Total operating lease liability $ 3,012

Reserve for Losses and Loss Adjustment Expenses
Reserve for Losses and Loss Adjustment Expenses	9 . Reserve for Losses and Loss Adjustment Expenses Loss and loss adjustment expenses reserves represent management’s best estimate of the ultimate cost of all reported and unreported losses incurred for the years ended December 31, 2020, 2019, and 2018. The Company does not discount loss and loss adjustment expense reserves. The reserves for unpaid losses and loss adjustment expenses are estimated using individual case‑basis valuations and statistical analyses. Those estimates are subject to the effects of trends in loss severity and frequency. In addition to case reserves, which are generally based on reported claims, the Company establishes reserves for incurred but not reported claims (“IBNR”). IBNR reserves are developed to provide for (i) the estimated amount of future loss payments on incurred claims not yet reported, and (ii) potential development on reported claims. IBNR reserves are estimated based on generally accepted actuarial reserving techniques that consider quantitative loss experience data and, where appropriate, qualitative factors. With the assistance of an independent, actuarial firm, the Company uses statistical analysis to estimate the cost of losses and loss adjustment expenses related to IBNR. Those estimates are based on historical information, industry information and practices, and estimates of trends that may affect the ultimate frequency of incurred but not reported claims and changes in ultimate claims severity. The Company regularly reviews its reserve estimates and adjusts them as necessary as experience develops or as new information becomes known. Such adjustments are included in current operations. During the loss settlement period, if there are indications that claims frequency or severity exceeds initial expectations, the Company generally increases its reserves for losses and loss adjustment expenses. Conversely, when claims frequency and severity trends are more favorable than initially anticipated, the Company generally reduces its reserves for losses and loss adjustment expenses once it has sufficient data to confirm the validity of the favorable trends. Even after such adjustments, the ultimate liability may exceed or be less than the revised estimates. Accordingly, the ultimate settlement of losses and the related loss adjustment expenses may vary significantly from the estimate included in the Company’s consolidated financial statements. Although considerable variability is inherent in such estimates, management believes the reserves for losses and loss adjustment expenses are adequate. The estimates are continually reviewed and adjusted as necessary as experience develops or new information becomes known. Any adjustments to estimates are recorded in the current period. The following table provides a reconciliation of the beginning and ending reserve balances for losses and LAE on a net of reinsurance basis to the gross amounts reported in the accompanying consolidated balance sheets: Year Ended December 31, 2020 2019 2018 (in thousands) Reserve for losses and loss adjustment expenses net of reinsurance recoverables at beginning of period $ 3,869 $ 4,165 $ 4,432 Add: Incurred losses and loss adjustment expenses, net of reinsurance, related to: Current year 64,179 5,774 8,165 Prior years (64) (181) (1,891) Total incurred 64,115 5,593 6,274 Deduct: Loss and loss adjustment expense payments, net of reinsurance, related to: Current year 31,879 2,179 4,409 Prior years 1,635 3,710 2,132 Total payments 33,514 5,889 6,541 Reserve for losses and loss adjustment expense net of reinsurance recoverables at end of period 34,470 3,869 4,165 Add: Reinsurance recoverables on unpaid losses and loss adjustment expenses at end of period 94,566 12,952 11,896 Reserve for losses and loss adjustment expenses gross of reinsurance recoverables on unpaid losses and loss adjustment expenses at end of period $ 129,036 $ 16,821 $ 16,061 The foregoing reconciliation shows loss and loss adjustment expense reserve redundancies of $0.1 million, $0.2 million, and $1.9 million developed in 2020, 2019 and 2018, respectively. During 2020, this favorable reserve development related to lower than anticipated frequency and severity of claims in our homeowners and special property lines of business offset by higher than anticipated frequency and severity of claims in our assumed reinsurance line. During 2019, this favorable reserve development was primarily related to lower than originally anticipated frequency and severity of claims in our homeowners lines of business, offset by higher than originally anticipated frequency and severity of claims in our special property lines of business. During 2018, this favorable reserve development was primarily due to favorable development in our homeowners lines of business due to lower than originally anticipated frequency and severity of claims. The Company compiles and aggregates its claims data by grouping the claims according to the year in which the claim occurred (“Accident Year”) when analyzing claim payment and emergence patterns and trends over time. For the purpose of defining claims frequency, the number of reported claims is by loss occurrence and includes claims that do not result in a liability or payment associated with them. The Company analyzed the usefulness of disaggregation of its results and determined the characteristics associated with the policies and the related unpaid loss reserves, incurred losses, and payment patterns are similar in nature. The Company separates its special property and other claim experience from its homeowner claim experience when analyzing losses and allocated loss adjustment expenses incurred and paid development and claim count triangles, as there are distinct differences in the development and claim count emergence patterns as well as methods of IBNR projection. The Special Property classification includes fire, allied lines, inland marine, and earthquake claims. As such, the following tables show the Company’s historical homeowner and special property incurred and cumulative paid losses and LAE development, net of reinsurance, as well as IBNR loss reserves and the number of reported claims on an aggregate basis as of December 31, 2020 for each of the previous two accident years. The information provided herein about incurred and paid accident year claims development for the years ended December 31, 2018 and prior is presented as unaudited supplementary information.

This amount reflects gross and net reserves related to this treaty and the ultimate incurred amount reflects IBNR only. The Company does not have direct access to individual claim information underlying the assumed quota arrangement. The Company does not use claim frequency information in the determination of loss reserves or for other internal purposes. Based on these considerations, the Company does not believe providing claims frequency information is practicable as it relates to this line of business .

Reinsurance

Reinsurance
Reinsurance	10. Reinsurance The Company utilizes reinsurance in order to limit its exposure to losses and enable it to underwrite policies with sufficient limits to meet policyholder needs. The Company utilizes both excess of loss (XOL) and quota share reinsurance. In an XOL treaty, the Company retains losses for any occurrence up to a specified amount (its “retention”) and reinsurers assume any losses above that amount. Historically, the Company has had a retention of between $5 million and $15 million for hurricane and earthquake events. As of December 31, 2020, the Company’s catastrophe event retention is $10 million for all perils and $1 million as a vertical co-participation in selected layers. As of December 31, 2020, the Company’s XOL reinsurance structure provides protection up to $1.4 billion for earthquake events and $600 million for hurricane events. In a quota share agreement, the Company transfers, or cedes, part or all of its exposure to a reinsurer who receives a portion of the associated premium in exchange. The reinsurer also must share an agreed upon portion of losses and agreed upon portion of the associated commission expense. The Company has quota share reinsurance agreements on several of its lines with the Commercial All Risk and Specialty Homeowners lines currently accounting for the largest amount of ceded written premiums. For Texas Homeowners, a component of Specialty Homeowners, the Company ceded substantially all exposure between June 2018 and June 2019 and ceded a significant portion of exposure thereafter. Ceded written premium related to the Texas Homeowners line was $14.6 million, $20.4 million and $24.9 million for the years ended December 31, 2020, 2019 and 2018, respectively. Ceded written premium related to the Commercial All Risk line was $19.2 million, $19.0 million and $7.2 million for the years ended December 31, 2020, 2019 and 2018, respectively. The Company also began ceding a small portion of its Commercial Earthquake premiums in November 2020, which accounted for approximately $7.1 million in ceded written premiums for the year ended December 31, 2020. No other quota share program accounted for more than 10% of total ceded written premiums for those years. The Company recognizes ceded unearned premiums related to quota share agreements as an asset on its consolidated balance sheets. As of December 31, 2020 and 2019, ceded unearned premiums totaled $35.0 million and $26.1 million, respectively. The increase was driven primarily by premium growth in lines subject to quota shares and the timing at which the Company entered quota share arrangements. As part of its reinsurance program, in May 2017, the Company obtained catastrophe protection through a reinsurance agreement with Torrey Pines Re Ltd. (“TPRe”). In connection with the reinsurance agreement, TPRe issued notes to unrelated investors in an amount equal to the full $166 million of coverage provided under the reinsurance agreement covering a three-year period, ending May 31, 2020. At the time of the agreement, the Company performed an evaluation of TPRe to determine if it meets the definition of a variable interest entity (“VIE”). The Company concluded that TPRe is a VIE but it does not have a variable interest in the entity, as the variability in results is expected to be absorbed entirely by the investors in TPRe. Accordingly, TPRe is not consolidated in the Company’s financial statements. The premium ceded to TPRe for the year ended December 31, 2020 was approximately $5.0 million. The effect of reinsurance on premiums written and earned and on losses and LAE incurred for the years ended December 31, 2020, 2019 and 2018, is as follows: 2020 2019 2018 Written Earned Written Earned Written Earned (in thousands) Premiums Written and Earned: Direct $ 324,253 $ 271,887 $ 220,568 $ 178,536 $ 144,821 $ 129,071 Assumed 30,107 29,569 31,393 21,985 10,070 8,688 Ceded (155,102) (146,388) (108,332) (100,314) (82,949) (67,862) Net $ 199,258 $ 155,068 $ 143,629 $ 100,207 $ 71,942 $ 69,897 2020 Losses LAE Total (in thousands) Losses and LAE Incurred: Direct $ 145,774 $ 18,777 $ 164,551 Assumed 3,485 159 3,644 Ceded (91,969) (12,111) (104,080) Net $ 57,290 $ 6,825 $ 64,115 2019 Losses LAE Total (in thousands) Losses and LAE Incurred: Direct $ 20,105 $ 2,837 $ 22,942 Assumed 1,201 34 1,235 Ceded (16,564) (2,020) (18,584) Net $ 4,742 $ 851 $ 5,593 2018 Losses LAE Total (in thousands) Losses and LAE Incurred: Direct $ 12,153 $ 2,113 $ 14,266 Assumed 46 6 52 Ceded (6,580) (1,464) (8,044) Net $ 5,619 $ 655 $ 6,274 The ceding of insurance does not legally discharge the Company from its primary liability for the full amount of the policy coverage, and therefore the Company will be required to pay the loss and bear collection risk if the reinsurer fails to meet its obligations under the reinsurance agreement. To minimize exposure to significant losses from reinsurance insolvencies, the Company evaluates the financial condition of its reinsurers and monitors concentrations of credit risk. To reduce credit exposure to reinsurance recoverable balances, the Company obtains letters of credit from certain reinsurers that are not authorized as reinsurers under U.S. state insurance regulations. In addition, under the terms of its reinsurance contracts, the Company may retain funds due from reinsurers as security for those recoverable balances. As of December 31, 2020 and 2019, the Company had retained $4.5 million and $1.7 million in funds from reinsurers, respectively. The Company is able to use the funds in the ordinary course of its business. The funds are held in cash and cash equivalents and investments with an offsetting liability on the accompanying consolidated balance sheets. For the year ended December 31, 2020, reinsurance premiums ceded to the Company’s three largest reinsurers totaled $9.7 million, $8.6 million, and $6.0 million, representing 22.4% of the total balance. For the year ended December 31, 2019, reinsurance premiums ceded to the Company’s three largest reinsurers totaled $21.7 million, $7.5 million, and $4.9 million, representing 31.5% of the total balance. For the year ended December 31, 2018, reinsurance premiums ceded to the Company’s three largest reinsurers totaled $7.5 million, $7.2 million, and $5.2 million, representing 24.0% of the total balance. At December 31, 2020 reinsurance recoverable on unpaid losses by the Company’s three largest reinsurers were $36.0 million, $5.8 million, and $3.1 million representing 42.8% of the total balance. At December 31, 2019 reinsurance recoverables on paid and unpaid losses by the Company’s three largest reinsurers were $2.7 million, $1.9 million, and $1.9 million representing 38.2% of the total balance. All of the Company’s reinsurers post collateral or have an A.M. best rating of A− (excellent) or better.

Long-term Debt
Long-term Debt	11. Long‑term Debt Prior to September 2018, the Company had $17.5 million in outstanding surplus notes which had been issued by PSIC on February 3, 2015 for a term of seven years. The surplus notes bore interest at the rate of LIBOR plus 8.00% and had restrictions as to payments of interest and principal and any such payment required the prior approval of the Oregon Insurance Commissioners before such payment could be made. Such payments could only be made from surplus. In September 2018, the Company completed a private placement financing of $20.0 million floating rate senior secured notes (the “Floating Rate Notes”), bearing interest at the three-month treasury rate plus 6.50% per annum. As part of the financing agreement, the Company immediately used surplus funds to pay down the existing $17.5 million in surplus notes. As part of this pre‑payment, the Company incurred a penalty of $0.1 million which, along with unamortized debt issuance costs of $0.4 million, was charged to income in 2018. The Floating Rate Notes were redeemed pursuant to their terms on May 23, 2019, at a redemption price equal to 102% of the principal amount of the Floating Rate Notes, or $20.4 million (plus $0.3 million of accrued and unpaid interest thereon). The Company recognized a charge of $1.3 million upon redemption with $0.4 million due to the redemption premium and $0.9 million due to the write‑off of unamortized debt issuance costs. The $0.4 million redemption premium was recognized as a component of interest expense and the $0.9 million issuance cost write‑off was recognized as a component of other underwriting expenses in the Company’s consolidated statements of income and comprehensive income. The Company incurred $1.1 million in interest expense related to the Floating Rate Notes for the year ended December 31, 2019 (inclusive of the $0.4 million redemption premium) and $0.6 million for the year ended December 31, 2018 and paid $1.2 million and $0.5 million for each period, respectively. The Company incurred and paid $1.2 million in interest expense related to the surplus notes for the year ended December 31, 2018.

Stockholders’ Equity As of December 31, 2020 and December 31, 2019, the Company has 5,000,000 preferred shares authorized with a par value of $0.0001 and no preferred shares issued and outstanding. As of December 31, 2020 and December 31, 2019, the Company has 500,000,000 common shares authorized and 25,525,796 and 23,468,750 common shares issued and outstanding, respectively, with a par value of $0.0001. Additional paid in capital is $310.5 million as of December 31, 2020 and $180.0 million as of December 31, 2019. In March 2019, the Company made a one-time cash distribution totaling approximately $5.1 million to its then-sole stockholder, GC Palomar Investor LP, enabling it to distribute funds to its partners in order to allow such partners to satisfy tax obligations incurred as a result of the Domestication transactions. On April 22, 2019, the Company completed its IPO with the sale of 6,468,750 shares of common stock at a price to the public of $15.00 per share. The Company received net proceeds of approximately $87.4 million, after deducting underwriting discounts and commissions and offering costs. On January 9, 2020, the Company sold 750,000 shares of common stock to the public at a price of $49.00 per share (along with 5,000,000 shares sold by existing stockholders) in an underwritten public offering. The Company received net proceeds of approximately $35.5 million, after deducting underwriting discounts and commissions and offering costs. On June 26, 2020, the Company sold 1,150,000 shares of common stock to the public at a price of $82.00 per share in an underwritten public offering. The Company received net proceeds of approximately $90.1 million, after deducting underwriting discounts and commissions and offering costs. Common stock reserved for future issuance consists of the following as of December 31, 2020: Stock options outstanding under 2019 Equity Incentive Plan 1,008,648 Restricted stock units outstanding under 2019 Equity Incentive Plan 14,734 Shares authorized for future issuance under 2019 Equity Incentive Plan 1,952,001 Shares authorized for future issuance under 2019 Employee Stock Purchase Plan 451,633 Total 3,427,016 The below table summarizes the Company’s stock-based compensation expense for each period presented: Year ended December 31, 2020 2019 2018 (in thousands) Stock-Based Compensation Expense $ 2,167 $ 24,103 $ — Stock-based compensation expense is recognized on a straight-line basis over the vesting period of awards. The Company does not apply a forfeiture rate to unvested awards and accounts for forfeitures as they occur. All stock-based compensation is included in other underwriting expenses in the Company’s consolidated statements of income and comprehensive income. The Company recognized approximately $23.0 million of stock-based compensation expense in March 2019 relating to the modification of its 2014 Management Incentive Plan. The Company began recognizing stock-based compensation expense relating to its 2019 Equity Incentive Plan and the 2019 Employee Stock Purchase Plan upon their inception and initial equity grants in April 2019. Aside from the aforementioned $23.0 million charge, all stock-based compensation expense recognized during the years ended December 31, 2020 and December 31, 2019 relates to the 2019 Equity Incentive Plan and 2019 Employee Stock Purchase Plan. Management Incentive Plan prior to IPO The Company’s former parent, GC Palomar Investor LP, adopted a 2014 Management Incentive Plan (in the form of profits interests) on February 12, 2014 under which certain officers and employees of PSIC and its affiliates were entitled to Class P Units in GC Palomar Investor LP. Class P unit holders were expected to realize value only upon the occurrence of liquidity events meeting requisite financial thresholds after the Class A unit holders recovered their investment. The Class P unit holders had no voting rights. The Company did not record stock-based compensation expense related to this plan prior to 2019 because no liquidity events were probable of occurring. On March 15, 2019, the Company modified its 2014 Management Incentive Plan by eliminating the requirement of a liquidity event to occur for the holders of its Class P units to realize value. The 12,552,825 Class P units outstanding were modified such that the vesting of each Class P unit holder’s awards was accelerated and their Class P distribution percentages were determined and distributed based on these percentages. This modification resulted in a stock compensation charge and corresponding increase to additional paid in capital of $23.0 million during the quarter ending March 31, 2019. The stock compensation charge is included in other underwriting expenses in the Company’s consolidated statements of income and comprehensive income. 2019 Equity Incentive Plan On April 16, 2019, the Company’s 2019 Equity Incentive Plan (“the 2019 Plan”) became effective. The 2019 Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”), performance shares and units, and other cash-based or share-based awards. In addition, the 2019 Plan contains a mechanism through which the Company may adopt a deferred compensation arrangement in the future. A total of 2,400,000 shares of common stock are initially authorized and reserved for issuance under the 2019 Plan. This reserve increases on January 1 of each year through 2029 , by an amount equal to the smaller of: 3% of the number of shares of common stock issued and outstanding on the immediately preceding December 31, or an amount determined by the board of directors. Stock Options Recipients of stock options can purchase shares of the Company’s common stock at a price equal to the stock’s fair market value on the grant date, determined by the closing price of the Company's common stock on the grant date. Stock options vest over a two or four year period with 25% or 50% vesting on the first anniversary of the grant date and the remainder vesting monthly over the remaining period, subject to continued service to the Company. Stock options expire ten years after the grant date. The following table summarizes stock option transactions for the year ended December 31, 2020: Weighted average remaining Aggregate Number of Weighted-average contractual term intrinsic value shares exercise price (in years) (in thousands) Outstanding at January 1, 2020 1,046,373 $ 17.05 $ 35,039 Options granted 109,374 80.90 Options exercised (122,613) 16.65 Options canceled (24,486) 21.46 Outstanding at December 31, 2020 1,008,648 $ 23.92 $ 66,028 Vested and Exercisable at December 31, 2020 522,464 $ 15.78 8.29 $ 38,170 The total intrinsic value of stock options exercised during the year ended December 31, 2020 was $7.7 million. No options were exercised prior to 2020. As of December 31, 2020, the Company had approximately $3.7 million of total unrecognized stock-based compensation expense related to stock options expected to be recognized over a weighted-average period of 2.27 years. The fair value of each option granted was estimated on the grant date using the Black-Scholes option pricing model with the following assumptions in each year presented: Year ended December 31, 2020 2019 2018 (in thousands) Risk free rate of return (1) 0.32% - 1.52% 1.59% - 2.45% — Expected share price volatility (2) 18.13% - 25.67% 18.12% - 18.45% — Expected life in years (3) 5.63-6.08 5.64-6.08 — Dividend yield (4) — (1) Determined based on the U.S. Treasury yield in effect at the time of the grant for zero-coupon U.S. Treasury notes with remaining terms similar to the expected term of the options. (2) Determined based on analysis of the historical volatility of a peer group of publicly traded companies. (3) Determined using the “simplified method” for estimating the expected option life, which is the average of the weighted-average vesting period and contractual term of the option as the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term due to the limited period of time its common stock has been publicly traded. (4) Determined to be zero as the Company does not currently plan to issue dividends. Restricted Stock Units Restricted stock units are valued on their grant date and generally vest either on the first anniversary of the grant date or over a three-year period with one third vesting on each anniversary date, subject to continued service with the Company. The fair value of RSUs is determined using the closing price of the Company's common stock on the grant date. The following table summarizes RSU transactions for the year ended December 31, 2020: Weighted-average Number of grant date shares fair value Non vested outstanding at January 1, 2020 6,066 $ 16.49 Granted 14,734 95.86 Vested (6,066) 16.49 Forfeited — — Non vested outstanding at December 31, 2020 14,734 $ 95.86 As of December 31, 2020, the Company had approximately $1.2 million of total unrecognized stock-based compensation expense related to RSUs expected to be recognized over a weighted-average period of 2.41 years. 2019 Employee Stock Purchase Plan On April 16, 2019, the Company's 2019 Employee Stock Purchase Plan (“the 2019 ESPP”) became effective. A total of 240,000 shares of common stock are initially authorized and reserved for issuance under the 2019 ESPP. In addition, the 2019 ESPP provides for annual increases in the number of shares available for issuance on January 1 of each year through 2029, equal to the smaller of 240,000 shares of the Company’s common stock or such other amount as may be determined by the board of directors. Under the 2019 ESPP, employees can purchase Company stock at a discount via payroll withholdings. The 2019 ESPP is administered through employee participation in discrete offering periods. During each discrete offering period employee funds are withheld, and the stock purchase occurs upon the conclusion of the offering period. The Company issued 28,367 shares pursuant to the ESPP during the year ended December 31, 2020.

Income Taxes
Income Taxes	16. Income Taxes Prior to March 2019, the Company was a Cayman Islands incorporated holding company with U.K. tax residency. On March 14, 2019, the Company implemented a domestication (“the Domestication”) pursuant to Section 388 of the Delaware General Corporation Law and Section 206 of the Companies Law (2018 Revision), as amended, of the Cayman Islands pursuant to which it became a Delaware corporation and no longer subject to the laws of the Cayman Islands. Historically, the Company’s Bermuda based subsidiary, PSRE, was not required to pay any taxes on its income or capital gains but was subject to a 1% U.S. federal excise tax on reinsurance premiums assumed. The Company has elected for PSRE to be taxed as a U.S. domestic corporation under Section 953(d) of the Code effective January 1, 2019. The components of the Company’s federal income tax expense (benefit) are as follows: December 31, 2020 2019 2018 (in thousands) Current $ (1,128) $ 6,810 $ (6) Deferred 1,094 646 — Income tax expense (benefit) $ (34) $ 7,456 $ (6) As of December 31, 2020 and 2019, significant components of the Company’s deferred tax assets and liabilities were as follows: December 31, 2020 2019 (in thousands) Deferred tax assets: Losses and LAE reserve discount $ 238 $ 10 Net operating losses 680 74 Investment amortization — 85 Unearned premiums 6,272 3,748 Capitalized organizational costs 244 274 Deferred compensation 511 — Other 652 390 Total deferred tax assets $ 8,597 $ 4,581 Deferred tax liabilities: Deferred acquisition costs $ (7,454) $ (4,468) Unrealized gains on investments (3,884) (1,396) Internally developed software (1,283) (640) Other (672) (2) Total deferred tax liabilities (13,293) (6,506) Net deferred tax liability before valuation allowance (4,696) (1,925) Valuation allowance (680) (74) Total net deferred tax liabilities $ (5,376) $ (1,999) The valuation allowance shown above relates to deferred tax assets associated with state net operating loss carryforwards. These carryforwards do not meet the “more likely than not” criteria under ASC 740, Income Taxes due to the limited carryforward period. The amount of the deferred tax assets considered realizable could be adjusted if estimates of future taxable income during the carryforward period change or if objective negative evidence in the form of cumulative losses is no longer present. The following is a reconciliation of the statutory federal income tax rate to the Company’s effective tax rate for the tax years ended December 31, 2020, 2019 and 2018: Years Ended December 31, 2020 2019 2018 ($ in thousands) Expense computed at federal tax rate $ 1,321 21.00 % $ 3,802 21.00 % $ 3,825 21.00 % Non‑U.S. group member income — — % — — % (4,409) (24.21) % Stock-based compensation (1,538) (24.44) % 4,822 26.63 % — — % Dividend received deduction and tax‑exempt interest (67) (1.06) % (36) (0.20) % (144) (0.79) % Valuation allowance 606 9.63 % (1,677) (9.27) % 678 3.72 % Other (356) (5.67) % 545 3.01 % 44 0.24 % Income tax expense (benefit) $ (34) (0.54) % $ 7,456 41.17 % $ (6) (0.04) % The stock-based compensation difference shown above relates primarily to the permanent component of employee stock option exercises for the year ended December 31, 2020. For the year ended December 31, 2019, this difference relates primarily to a non-deductible stock compensation charge of $23.1 million incurred by the Company in March 2019. For the year ended December 31, 2020, the Company increased its valuation allowance relating to deferred tax assets associated with state net operating losses. The Company reversed the valuation allowance on its U.S. tax attributes during the year ended December 31, 2019 because of Domestication in the United States and projected future operating income in the U.S. As of December 31, 2020 and 2019, the Company had no uncertain tax positions that required either recognition or disclosure in the consolidated financial statements. This is not expected to change significantly during the next twelve months. The Company classifies interest and penalties, if any, related to the liability for unrecognized tax benefits as a component of the provision for income taxes. The Company’s income tax returns for 2015 through 2019 remain subject to examination by the tax authorities.

Statutory financial information
Statutory financial information	18. Statutory financial information U.S. U.S. state insurance laws and regulations prescribe accounting practices for determining statutory net income and capital and surplus for insurance companies. In addition, state regulators may permit statutory accounting practices that differ from prescribed practices. Statutory accounting practices (“SAP”) prescribed or permitted by regulatory authorities for the Company’s insurance subsidiaries differ from U.S. GAAP. The principal differences between SAP and GAAP as they relate to the financial statements of the Company’s insurance subsidiaries are (a) policy acquisition costs are expensed as incurred under SAP, whereas they are deferred and amortized under GAAP, (b) certain assets are not admitted for purposes of determining surplus under SAP, (c) investments in fixed income securities are carried at fair value under GAAP whereas such securities are carried at amortized cost under SAP, and (d) the criteria for recognizing net DTAs and the methodologies used to determine such amounts are different under SAP and GAAP. Combined statutory net income and statutory capital surplus for the U.S. insurance subsidiaries, PSIC and PESIC as of December 31, 2020, 2019 and 2018 and for the years then ended are summarized as follows: December 31, 2020 2019 2018 (in thousands) Statutory net income (loss) $ 1,753 $ (17,911) $ 9,609 Statutory capital and surplus 213,721 116,296 63,731 Risk‑Based Capital (“RBC”) requirements promulgated by the NAIC require property/casualty insurers to maintain minimum capitalization levels determined based on formulas incorporating various business risks of the insurance subsidiaries. As of December 31, 2020 and 2019, the company’s capital and surplus exceeds its authorized control level. Bermuda Under the Bermuda Insurance Act, 1978 and related regulations, PSRE is required to maintain certain solvency and liquidity levels. The minimum statutory solvency margin required at December 31, 2020 and 2019 was approximately $1.2 million and $1.2 million, respectively. Actual statutory capital and surplus at December 31, 2020 and 2019 was $39.2 million and $38.3 million, respectively. PSRE had statutory net income of $0.9 million, $18.5 million and $17.3 million for 2020, 2019 and 2018, respectively. PSRE had stockholder’s equity of $41.9 million and $39.7 million on a GAAP basis at December 31, 2020 and 2019, respectively. The principal difference between statutory capital and surplus and stockholder’s equity presented in accordance with GAAP are prepaid expenses, which are non‑admitted assets for Bermuda statutory purposes. PSRE maintains a Class 3A license and thus must maintain a minimum liquidity ratio in which the value of its relevant assets is not less than 75.0% of the amount of its relevant liabilities for general business. Relevant assets include cash and cash equivalents, fixed maturity securities, accrued interest income, premiums receivable, losses recoverable from reinsurers, and funds withheld. The relevant liabilities include total general business insurance reserves and total other liabilities, less sundry liabilities. As of December 31, 2020 and 2019, the Company met the minimum liquidity ratio requirement.

Dividend Restrictions
Dividend Restrictions	19. Dividend Restrictions U.S. The Company’s U.S. insurance company subsidiaries, PSIC and PESIC are restricted by the statutes as to the amount of dividends that they may pay without prior approval by state insurance commissioners. Under California and Oregon statute which govern PSIC, dividends paid in a consecutive twelve month period cannot exceed the greater of (i) 10% of an insurance company’s statutory policyholders’ surplus as of December 31 of the preceding year or (ii) 100% of its statutory net income for the preceding calendar year. Any dividends or distributions in excess of these amounts would require regulatory approval. In addition, under Oregon statute, PSIC may only declare a dividend from earned surplus, which does not include contributed capital. Surplus arising from unrealized capital gains or revaluation of assets is not considered part of earned surplus. Based on the above restrictions, PSIC may pay a dividend or distribution of no greater than $11.3 million in 2021 without approval by the California and Oregon Insurance Commissioners. Under Arizona statute with governs PESIC, dividends paid in a consecutive twelve month period cannot exceed the lesser of (i) 10% of an insurance company’s statutory policyholders’ surplus as of December 31 of the preceding year or (ii) 100% of its statutory net income for the preceding calendar year. As such, PESIC is unable to pay a dividend or distribution in 2021 without the approval of the Arizona Insurance Commissioner as it had a statutory net loss in 2020. In addition to the above limitations, any dividend or distribution declared is also subject to state regulatory approval prior to payment. In the future, state insurance regulatory authorities may adopt statutory provisions and dividend limitations more restrictive than those currently in effect. Bermuda Bermuda regulations limit the amount of dividends and return of capital paid by a regulated entity. A Class 3A insurer is prohibited from declaring or paying a dividend if it is in breach of its minimum solvency margin, its enhanced capital requirement, or its minimum liquidity ratio, or if the declaration or payment of such dividend would cause such a breach, or if there are reasonable grounds for believing there has been such a breach. Pursuant to Bermuda regulations, the maximum amount of dividends and return of capital available to be paid by a reinsurer is determined pursuant to a formula. Under this formula, the maximum amount of dividends and return of capital available to the Company from PSRE during 2021 is calculated to be approximately $10.5 million. However, this dividend amount is subject to annual enhanced solvency requirement calculations.

The bank letters of credit amount to $1.5 million, $0.5 million and $0.4 million. The $1.5 million and $0.4 million letters of credit expire December 31, 2021 with no renewal terms. The $0.4 million letter of credit auto renews each year.

All intercompany balances and transactions have been eliminated in consolidation.
Stock Split	Stock Split On March 15, 2019, the Company effected a 17,000,000 for one forward stock split in conjunction with domestication in the United States. All share and per share information included in the accompanying consolidated financial statements and notes to the consolidated financial statements have been retroactively adjusted to reflect the stock split for the Company’s common stock for all periods presented.
Initial Public Offering (IPO)	Initial Public Offering (“IPO”) On April 22, 2019, the Company completed its IPO with the sale of 6,468,750 shares of common stock at a price to the public of $15.00 per share, including 843,750 shares sold upon the exercise in full of the underwriter’s option to purchase additional shares. After underwriter discounts and commissions and offering expenses, net proceeds from the IPO were approximately $87.4 million.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein. All revisions to accounting estimates are recognized in the period in which the estimates are revised. Significant estimates reflected in the Company’s consolidated financial statements include, but are not limited to, reserves for losses and loss adjustment expenses, reinsurance recoverables on unpaid losses, and the fair values of investments.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include time deposits and marketable securities with original maturities of three months or less at acquisition and are stated at cost, which approximates fair value. The Company maintains cash balances in federally insured financial institutions.
Restricted Cash	Restricted Cash Restricted cash includes cash on deposit with reinsurance carriers. Restricted cash also includes cash held in a fiduciary capacity for the benefit of third-party insurance carriers.
Investments	Investments All of the Company’s investments in fixed maturity securities are classified as available‑for‑sale and are carried at fair value. Investment income consists primarily of interest and dividends. Interest income is recognized on an accrual basis. Premiums and discounts on mortgage‑backed securities and asset‑backed securities are amortized or accrued using the prospective method which considers anticipated prepayments at the date of purchase. To the extent that the estimated lives of such securities change as a result of changes in estimated prepayment rates, the adjustments are included in net investment income using the prospective method. Dividend income is recognized on the ex‑dividend date. Net investment income represents investment income, net of expenses. Unrealized gains and losses related to fixed maturity securities are included in accumulated other comprehensive income as a separate component of stockholders’ equity. Equity securities are carried at fair value with unrealized gains and losses included as a component of net income on the Company’s consolidated statement of income and comprehensive income. The Company uses the specific‑identification method to determine the cost of fixed maturity securities sold and the first‑in, first‑out method for lots of equity securities sold. The Company reviews all securities with unrealized losses on a quarterly basis to assess whether the decline in the securities fair value necessitates the recognition of an allowance for credit losses. Factors considered in the review include the extent to which the fair value has been less than amortized cost, and current market interest rates and whether the unrealized loss is credit‑driven or a result of changes in market interest rates. The Company also considers factors specific to the issuer including the general financial condition of the issuer, the issuers industry and future business prospects, any past failure of issuer to make scheduled interest or principal payments, and the payment structure of the investment and the issuers ability to make contractual payments on the investment. The Company also considers whether it intends to sell the security or if it is more likely than not that it will be required to sell the security before recovery of its amortized cost. When assessing whether it intends to sell a fixed-maturity security or if it is likely to be required to sell a fixed-maturity security before recovery of its amortized cost, the Company evaluates facts and circumstances including, but not limited to, decisions to reposition the investment portfolio, potential sales of investments to meet cash flow needs, and potential sales of investments to capitalize on favorable pricing. For fixed-maturity securities where a decline in fair value is below the amortized cost basis and the Company intends to sell the security, or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, a credit-loss charge is recognized in net income based on the fair value of the security at the time of assessment. For fixed-maturity securities that the Company has the intent and ability to hold, the Company compares the estimated present value of the cash flows expected to be collected to the amortized cost of the security. The extent to which the estimated present value of the cash flows expected to be collected is less than the amortized cost of the security represents the credit-related portion of the impairment, which is recognized in net income through an allowance for credit losses. Any remaining decline in fair value represents the noncredit portion of the impairment, which is recognized in other comprehensive income. The Company reports accrued interest receivable as a component of accrued investment income on its consolidated balance sheet which is presented separately from available-for-sale securities. The Company does not measure an allowance for credit losses on accrued interest receivable and instead would write off accrued interest receivable at the time an issuer defaults or is expected to default on payments. Prior to the adoption of ASU 2016-13, the Company evaluated fixed maturity securities for credit losses and any losses were bifurcated into the credit‑related loss and the loss related to all other factors. The credit‑related impairment loss would have been recognized as a realized loss in the statement of income and comprehensive income and the cost basis of the security would have been reduced. The impairment related to other factors would have remained in accumulated other comprehensive income. The Company did not recognize any credit losses during the years ended December 31, 2020 and 2019 related to its available-for-sale securities.
Fair Value	Fair Value Fair value is defined as the price that the Company would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. The three‑tier hierarchy of inputs is summarized in the three broad levels listed below: Level 1—Unadjusted quoted prices are available in active markets for identical investments as of the reporting date. Level 2—Pricing inputs are quoted prices for similar investments in active markets; quoted prices for identical or similar investments in inactive markets; or valuation based on models where the significant inputs are observable or can be corroborated by observable market data. Level 3—Pricing inputs into models are unobservable for the investment. The unobservable inputs require significant management judgment or estimation. To measure fair value, the Company obtains quoted market prices for its investment securities from its outside investment managers. If a quoted market price is not available, the Company uses prices of similar securities. The fair values obtained from the outside investment managers are reviewed for reasonableness and any discrepancies are investigated for final valuation. The fair value of the Company’s investments in fixed maturity securities is estimated using relevant inputs, including available market information, benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. An Option Adjusted Spread model is also used to develop prepayment and interest rate scenarios. Industry standard models are used to analyze and value securities with embedded options or prepayment sensitivities. These fair value measurements are estimated based on observable, objectively verifiable market information rather than market quotes; therefore, these investments are classified and disclosed in Level 2 of the hierarchy. The fair value of the Company’s investments in equity securities is based on quoted prices available in active markets and classified and disclosed in Level 1 of the hierarchy.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, fixed maturity securities and reinsurance recoverables. The Company places its cash and cash equivalents with high credit quality financial institutions and its fixed maturity securities in securities of the U.S. government, U.S. government agencies, and high credit quality issuers of debt securities. The Company evaluates the financial condition of its reinsurers and reinsures its business with highly rated reinsurers and sometimes requires letters of credit or retains funds from reinsurers (see Note 10).
Premiums Receivable	Premiums Receivable Premiums receivable represent amounts due from policyholders, insurance agents, or program administrators for policies written. Generally, premiums are collected prior to providing risk coverage, minimizing the Company’s exposure to credit risk. Premiums receivable are short-term in nature and due within a year. The Company has established an allowance for uncollectable premiums related to its credit risk, which it reviews on a quarterly basis and adjusts as appropriate. The company considers the current economic environment, specific regulatory developments, and historic payment and cancelation trends by line of business and location when determining whether to record an allowance for uncollectable premiums. Prior to December 31, 2019, the Company did not have an allowance for uncollectable premiums. An initial allowance for uncollectable premiums of $0.2 million was established upon adoption of ASC 2016-13 on January 1, 2020 and the company recognized an immaterial amount of credit losses relating to uncollectable premiums during the year ended December 31, 2020.
Deferred Policy Acquisition Costs	Deferred Policy Acquisition Costs The costs of successfully acquiring new business, principally commission expense and premium taxes, are deferred and amortized over the terms of the policies in force, net of any ceding commissions.
Premiums Earned	Premiums Earned Gross premiums written are recorded at policy inception and are earned as revenue ratably over the term of the respective policies. Premiums written not yet recognized as revenue are reflected as unearned premiums on the balance sheet, or as advanced premiums if received prior to the policy effective date. Premiums written where cash is not yet received are recognized as premiums receivable. A premium deficiency is recognized if the sum of expected losses and loss adjustment expenses, unamortized acquisition costs, and policy maintenance costs exceeds the remaining unearned premiums. A premium deficiency would first be recognized by charging any unamortized acquisition costs to expense to the extent required to eliminate the deficiency. If the premium deficiency were greater than unamortized acquisition costs, a liability would be accrued for the excess deficiency. The Company does not consider anticipated investment income when determining if a premium deficiency exists. There was no premium deficiency at December 31, 2020 or 2019.
Commission and Other Income	Commission and Other Income Commission and other income is comprised of commissions earned on policies where the Company has no exposure to underlying risk and fees earned in conjunction with underwriting policies. Commission and fee income is earned at the time the policy is written.
Property and Equipment	Property and Equipment Property and equipment are capitalized and carried at cost less accumulated depreciation. Depreciation for property and equipment is calculated on a straight‑line basis using useful lives of 3 to 5 years. Leasehold improvements and other fixed assets are capitalized and depreciated over the useful lives of the properties and equipment. Expenditures for maintenance and repairs are charged to operations as incurred. Upon disposition, the asset cost and related depreciation are removed from the accounts and the resulting gain or loss is included in the Company’s results of operations.
Capitalized Software	Capitalized Software Costs associated with the implementation of certain internal systems are capitalized and carried at capitalized cost less accumulated amortization and are included as a component of prepaid expenses and other assets on the Company’s consolidated balance sheet. Costs capitalized include internal personnel costs, external developer costs, and interest. The implementation costs relate to systems built on software which the Company purchases under a cloud computing arrangement and accounts for as a service contract. As such, capitalized costs are amortized over the term of the service contract, which currently ends in December 2024.
Intangible Assets	Intangible Assets Intangible assets consist of both finite and indefinite lived assets. Finite lived intangible assets consist of customer relationships acquired from another insurer during 2020. Indefinite lived intangible assets consist of state licenses acquired upon formation of the Company. Intangible assets are initially recognized and measured at fair value and are subsequently evaluated for impairment annually or more frequently if circumstances warrant it. No impairments of intangible assets were recognized for the years ended December 31, 2020, 2019 or 2018.
Impairment of Long-Lived Assets	Impairment of Long‑Lived Assets Long‑lived assets with finite lives are tested for impairment whenever recognized events or changes in circumstances indicate the carrying value of these assets may not be recoverable. If indicators of impairment are present, the fair value is calculated using estimated future cash flows expected to be generated from the use of those assets. An impairment loss is recognized only if the carrying amount of a long‑lived asset or asset group is not recoverable and exceeds its fair value. The carrying amount of a long‑lived asset or asset group is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group. This assessment is based on the carrying amount of the asset or asset group at the date it is tested for recoverability. An impairment loss is measured as the amount by which the carrying amount of a long‑lived asset or asset group exceeds its fair value. No impairments of long‑lived assets were recognized for the years ended December 31, 2020, 2019 and 2018.
Reserve for Losses and Loss Adjustment Expenses	Reserve for Losses and Loss Adjustment Expenses The reserve for unpaid losses and loss adjustment expenses includes estimates for unpaid claims and claim adjustment expenses on reported losses and estimates of losses incurred but not reported (“IBNR”), net of salvage and subrogation recoveries. The liability is based on individual claims, case reserves and other estimates reported by policyholders, as well as management estimates of ultimate losses and loss adjustment expenses. Inherent in the estimates of ultimate losses and loss adjustment expenses are expected trends in claims severity and frequency and other factors that could vary significantly as claims are settled. The Company’s estimates of ultimate losses and loss adjustment expenses are based in part upon the estimation of claims resulting from natural disasters such as hurricanes and earthquakes. Estimation by management of the ultimate losses and loss adjustment expenses resulting from catastrophic events is inherently difficult because of the potential severity of property catastrophe claims. Therefore, the Company uses both proprietary and commercially available models, as well as historic claims experience, for purposes of providing an estimate of ultimate losses and loss adjustment expenses. Reserves for IBNR are established in accordance with industry practice to provide for (i) the estimated amount of future loss payments on incurred claims not yet reported, and (ii) potential development on reported claims. IBNR reserves are estimated based on generally accepted actuarial reserving techniques that consider quantitative loss experience data and, where appropriate, qualitative factors. Ultimate losses and loss adjustment expenses may vary materially from the amounts provided in the consolidated financial statements. Estimates of unpaid losses and loss adjustment expenses are reviewed regularly and, as experience develops and new information becomes known, the liabilities are adjusted as necessary. Such adjustments, if any, are reflected in operations in the period in which they become known and are accounted for as changes in estimates. The Company does not discount its liability for unpaid losses and loss adjustment expenses. The Company does not write insurance policies covering toxic clean‑up, asbestos‑related illness or other environmental remediation exposures.
Reinsurance	Reinsurance The Company purchases excess of loss and quota share reinsurance to protect it against the impact of losses. Reinsurance premiums, commissions, ceded unearned premiums are accounted for on bases consistent with the underlying terms of the reinsurance contracts and in proportion to the amount of insurance protection provided. The Company receives ceding commissions in connection with quota share reinsurance. The ceding commissions are capitalized and amortized as a reduction of acquisition expenses. Amounts applicable to ceded unearned premiums are reported as assets in the accompanying consolidated balance sheets. Premiums earned and losses and loss adjustment expenses incurred are stated in the accompanying consolidated statements of income and comprehensive income net of amounts ceded to reinsurers. Reinsurance recoverables represent balances due to the Company from its reinsurers for paid and unpaid losses and loss adjustment expenses. The Company is exposed to credit losses from reinsurers being unable to meet their obligations. The Company evaluates the financial condition of potential reinsurers and reinsures its business only with highly rated reinsurers with a rating of “A-“ (Excellent) (Outlook Stable) or better from A.M. Best. Reinsurers who do not meet the Company’s rating criteria are required to post collateral. The Company reviews credit quality of its reinsurers on a quarterly basis. The Company’s reinsurance contracts also include special termination provisions that allow the Company to cancel and replace any participating reinsurer that is downgraded below a rating of “A−” from A.M. Best, or whose surplus drops by more than 20%. Historically, the Company has not experienced any credit losses from reinsurance recoverables and did not have an allowance for uncollectable reinsurance recoverables as of December 31, 2020 or December 31, 2019.
Stock Based Compensation Expense	Stock Based Compensation Expense Stock-based compensation expense is recognized on a straight-line basis over the vesting period of awards. The Company does not apply a forfeiture rate to unvested awards and accounts for forfeitures as they occur. For stock option grants, the fair value of awards is estimated using the Black Scholes Model. The fair value of restricted stock units is determined using the closing price of the Company's common stock on the grant date. All stock-based compensation is included in other underwriting expenses in the Company’s consolidated statements of income and comprehensive income.
Income Taxes	Income Taxes The Company is taxed as a property/casualty insurer for federal income tax purposes. Deferred income tax assets and liabilities are determined based on the difference between the financial statement and the tax bases of assets and liabilities, using enacted tax rates expected to be in effect during the year in which the basis differences reverse. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized. The Company recognizes the tax benefit of uncertain tax positions where the position is more likely than not to be sustained assuming examination by taxing authorities. Based on its evaluation for the tax years ended December 31, 2020 and 2019, the Company has concluded that there are no significant uncertain tax positions requiring recognition in its financial statements. The Company recognizes interest and penalties related to uncertain tax positions, if any, as a component of income tax expense. The Company has not been assessed interest or penalties by any major tax jurisdictions for the respective tax years ended December 31, 2020, 2019, and 2018.
Earnings Per Share	Earnings Per Share Basic earnings per share is calculated by dividing net income by the weighted‑average common shares outstanding for the period. Diluted earnings per share reflects the dilution which could occur if equity-based awards are converted into common share equivalents as calculated using the treasury stock method. When inclusion of additional common share equivalents increases the earnings per share or reduces the loss per share, the effect on earnings per share is anti-dilutive, and the diluted net earnings or net loss per share is computed excluding these common share equivalents.
Recent Accounting Pronouncements	Recently adopted accounting pronouncements Clarification on change in filing status and prior quarterly information Prior to December 31, 2020, the Company qualified as an emerging growth company (“EGC”) under the Jumpstart Our Business Startups Act of 2012, or the JOBS Act. The Company was previously electing to adopt new or revised accounting guidance within the same time periods as private companies as permitted by its status as an EGC. The Company became a large accelerated filed on December 31, 2020 and must now adopt new accounting guidance within the same time periods as public companies, beginning with this 2020 Annual Report on Form 10-K. Prior to this annual report, the Company’s 2020 quarterly filings did not reflect adoption of the below guidance as the Company was not required to have adopted it. Upon adoption of the below guidance, the Company updated its financials as if the below guidance was adopted on January 1, 2020, however, this adoption had a negligible impact on previously filed quarterly information. Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued new guidance for accounting for leases, ASU 2016‑02, Leases (Topic 842) and subsequently issued multiple clarifying updates to the guidance. This updated guidance requires the recognition of a right‑of‑use (“ROU”) asset and a corresponding lease liability, discounted to the present value, for all leases that extend beyond 12 months. Under the previous guidance, leases were only included on the balance sheet if the criteria to classify the agreement as a capital lease were met. The Company adopted this new guidance as of January 1, 2020. The Company adopted this guidance using the modified retrospective transition method, applying the transition provisions on the date of adoption and not restating prior periods. The Company elected to use a number of practical expedients permitted under the transition guidance, but did not elect to use hindsight in determining the lease term. Upon adoption, the Company recognized a ROU asset of $2.9 million and lease liabilities of $3.8 million, with the difference representing the reclassification of deferred rent and lease incentive liabilities (the difference between the straight-line rent expenses and cash paid for rent under the leases) to operating lease ROU assets from other liabilities. The ROU asset and corresponding liability recognized pertained to various operating leases for office space. The Company did not have any cumulative-effect adjustment because of the adoption. Measurement of credit losses In June 2016, the FASB issued ASU 2016‑13, Financial Instruments-Credit Losses (Topic 326) and subsequently issued multiple clarifying updates to the guidance. This updated guidance requires financial assets measured at amortized cost to be presented at the net amount expected to be collected by means of an allowance for credit losses that is included in net income. Credit losses relating to available-for-sale debt securities are also required to be recorded through a reversible allowance for credit losses, but the allowance is limited to the amount by which fair value is less than amortized cost. The previous accounting guidance delayed the recognition of credit losses until it was probable a loss had been incurred. The Company adopted this guidance on January 1, 2020 using the modified retrospective approach and recorded a $0.2 million cumulative effect adjustment to beginning retained earnings upon adoption relating to an allowance for credit losses on the Company’s premium receivables. The adoption of this accounting guidance did not have an impact on value of the Company’s fixed maturity securities or its reinsurance recoverables. Recently issued accounting pronouncements not yet adopted Income Taxes In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. Among other things, ASU 2019-12 eliminates certain exceptions for recognizing deferred taxes for investments, performing intra-period tax allocation and calculating income taxes in interim periods. ASU 2019-12 also clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 is effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company will adopt this guidance in the first fiscal quarter of 2021 and does not expect adoption to have a material impact on its consolidated financial statements.
